fix(audiobooks): address native API review comments

Adds an Audiobooks entry to the sidebar and registers the two new
routes (/audiobooks for the library grid, /audiobooks/book/:id for
detail). The player renders inline inside the detail page; no
dedicated player route is required for MVP.

+### Database Migrations
+
+PostgreSQL schema migrations are managed by Goose. Migration SQL files live in
+`migrations/sql/` and use Goose annotations. Converted legacy migrations keep
+their original numeric versions so existing `schema_versions` rows can bootstrap
+cleanly into Goose without replaying old SQL. New migrations should be created
+with timestamped filenames:
+
+```sh
+make migrate-create NAME=add_thing
+make migrate-validate
+```
+
+Do not run `goose fix`; timestamped migrations are the repository policy because
+they avoid version collisions across parallel PRs. The existing `001`-style
+files are historical compatibility records, not the naming pattern for new work.
+Runtime migrations are applied by the integrated/API server only. Proxy and
+transcode modes never mutate schema.
+For existing installs, use `make migrate-status` and `make migrate-up` rather
+than invoking the Goose CLI directly; those targets copy legacy
+`schema_versions` rows into `public.goose_db_version` under the migration lock
+before reading or applying migrations. Set `ENV_FILE=path/to/.env` when the
+database URL should be read from a non-default env file.

-## PostgreSQL Performance Tuning
+## PostgreSQL Auto-Tuning
 
-The default PostgreSQL configuration is conservative and not optimized for any particular workload. For better performance, use [PGTune](https://pgtune.leopard.in.ua/) to generate settings tailored to your hardware.
-
-**Recommended PGTune settings:**
-
-| Setting | Value |
-|---|---|
-| DB Type | **Web application** |
-| Total Memory | Your server's RAM |
-| Number of CPUs | Your server's CPU count |
-| Number of Connections | 20 (Silo's default pool size) |
-| Data Storage | SSD or HDD depending on your setup |
-
-Silo's workload is predominantly read-heavy API queries (browse, search, metadata lookups) with the database small enough to fit in RAM for most libraries. The **Web application** profile optimizes for this: CPU-bound simple queries served from cached pages, high concurrent reads, and low write volume.
-
-If you have a very large library (50,000+ items) or heavy activity logging, consider switching to the **OLTP** profile instead.
-
-### Recommended Defaults for Modern Hardware
-
-Assuming you're using modern hardware with fast NVMe storage this is what I'm currently running.
-
-```ini
-# Connections
-max_connections = 100
-
-# Memory (tuned to keep PG under ~8GB total)
-shared_buffers = 4GB               # holds the entire DB in cache (typical DB is 1-4GB)
-effective_cache_size = 6GB         # planner hint only, not an allocation
-work_mem = 32MB                    # per-operation sort/hash memory
-maintenance_work_mem = 512MB       # VACUUM, CREATE INDEX, catalog imports
-
-# WAL / Write Performance
-wal_buffers = 64MB
-min_wal_size = 512MB
-max_wal_size = 2GB
-checkpoint_completion_target = 0.9
-
-# Storage (NVMe/Optane)
-random_page_cost = 1.1             # default 4.0; NVMe random ≈ sequential
-effective_io_concurrency = 200     # NVMe handles many concurrent requests
-
-# Parallelism
-max_worker_processes = 8
-max_parallel_workers_per_gather = 4
-max_parallel_workers = 8
-max_parallel_maintenance_workers = 4
-
-# Huge Pages
-huge_pages = try
-```
-
-These settings keep PostgreSQL under ~8GB of RAM while still caching the entire database. For HDD storage, change `random_page_cost` to `4.0` and `effective_io_concurrency` to `2`.
-
-### Applying Settings
-
-**Docker (recommended):** Save the settings above to a `postgresql.conf` file and mount it into your container:
+The default Docker Compose stack does not require a checked-in `postgresql.conf`.
+It enables Silo's [pgtune](https://github.com/le0pard/pgtune)-style OLTP tuning
+by default:
 
 ```yaml
-# docker-compose.yml
-postgres:
-  image: pgvector/pgvector:pg18
-  volumes:
-    - ./postgresql.conf:/etc/postgresql/postgresql.conf:ro
-  command: postgres -c config_file=/etc/postgresql/postgresql.conf
+POSTGRES_TUNE: auto
 ```
 
-Then restart: `docker compose restart postgres`
+When enabled, Silo connects with `DATABASE_URL` and applies recommendations with
+`ALTER SYSTEM`, which writes to PostgreSQL's `postgresql.auto.conf` inside the
+database data directory. Reloadable settings are applied immediately with
+`pg_reload_conf()`. Settings that PostgreSQL marks as restart-only are written
+too, and Silo logs the setting names so you can restart PostgreSQL once:
 
-**Existing PostgreSQL:** You can apply settings without editing config files using `ALTER SYSTEM`, which writes to `postgresql.auto.conf` inside the data directory:
-
-```sql
-ALTER SYSTEM SET work_mem = '32MB';
-ALTER SYSTEM SET effective_cache_size = '6GB';
-ALTER SYSTEM SET random_page_cost = 1.1;
-ALTER SYSTEM SET effective_io_concurrency = 200;
--- Apply without restart:
-SELECT pg_reload_conf();
-
--- These require a full restart:
-ALTER SYSTEM SET shared_buffers = '4GB';
-ALTER SYSTEM SET max_connections = 100;
-ALTER SYSTEM SET max_worker_processes = 8;
-ALTER SYSTEM SET huge_pages = 'try';
+```sh
+docker compose restart postgres
 ```
 
-Settings like `shared_buffers`, `max_connections`, `max_worker_processes`, and `huge_pages` require a PostgreSQL restart. Memory/planner settings (`work_mem`, `effective_cache_size`, `random_page_cost`) can be reloaded live.
+The default Compose database user has the required PostgreSQL permissions. If
+you use an external PostgreSQL server, make sure the configured `DATABASE_URL`
+user can run `ALTER SYSTEM`, or set `POSTGRES_TUNE=off` and manage
+PostgreSQL yourself.
+
+For `POSTGRES_TUNE_MEMORY=auto`, Silo uses the first trustworthy memory source:
+a finite Docker cgroup limit, the read-only `/host/proc/meminfo` mount supplied
+by the bundled Compose file, then `/proc/meminfo` with container safety guards.
+Auto-detected memory is treated as a PostgreSQL budget, defaulting to 75% of
+detected RAM so Silo, Redis, plugins, transcodes, and the OS retain headroom.
+`POSTGRES_TUNE_DB_SIZE=auto` queries `pg_database_size(current_database())` and
+classifies the workload by comparing the database size to that memory budget.
+
+Optional tuning overrides:
+
+| Variable | Default | Description |
+|---|---:|---|
+| `POSTGRES_TUNE_PROFILE` | `oltp` | Tuning profile. Only `oltp` is currently supported. |
+| `POSTGRES_TUNE_MEMORY` | `auto` | Server/container RAM, such as `8GB` or `32GB`; explicit values are used as-is. |
+| `POSTGRES_TUNE_MEMORY_BUDGET_PERCENT` | `75` | Percent of auto-detected RAM used for PostgreSQL recommendations. |
+| `POSTGRES_TUNE_CPUS` | `auto` | CPU count used for worker recommendations. |
+| `POSTGRES_TUNE_STORAGE` | `ssd` | One of `hdd`, `ssd`, `san`, or `nvme`. |
+| `POSTGRES_TUNE_DB_SIZE` | `auto` | Use `less_ram` when the database comfortably fits in RAM, `mid_ram`, or `greater_ram` for very large databases. |
+| `POSTGRES_TUNE_CONNECTIONS` | `100` | PostgreSQL `max_connections`; automatically raised if Silo's app pool is configured higher. |
+| `POSTGRES_SHM_SIZE` | `8gb` | Docker `/dev/shm` size for the bundled PostgreSQL container. |
+
+Advanced operators can still supply their own PostgreSQL configuration or
+override these env vars. Set `POSTGRES_TUNE=off` when you do not want Silo to
+change PostgreSQL server settings. Settings already written with `ALTER SYSTEM`
+remain in `postgresql.auto.conf`; reset those PostgreSQL parameters if you later
+move fully to a custom `postgresql.conf`.

-# ABS Wire-Shape Verification (post collections-unify cutover)
-
-Breadcrumbs for the next person debugging an ABS endpoint wire-shape issue
-after the canonical-tables cutover (migration 156 + commits `0dc830e`,
-`8c7fe1b`, `b64ce17`).
-
-The Go in-memory structs (`abs.Collection`, `abs.Playlist`,
-`abs.SmartCollection`, `abs.CollectionItem`, `abs.PlaylistItem`) have **no
-`json:"..."` struct tags**. The JSON wire contract is defined entirely by
-the `*ToABS()` map-builder helpers in `internal/audiobooks/abs/`. As long as
-the store layer populates the struct fields with the same values, the wire
-shape is preserved. The rewrites in `0dc830e`, `8c7fe1b`, `b64ce17` did NOT
-modify the emitters — only the SQL-backed store implementations.
-
-## Envelope tests — which one guards which endpoint
-
-Run with `go test ./internal/audiobooks/abs/ -run Envelope -v -count=1`.
-
-| Test file | Functions | Guards |
-|---|---|---|
-| `collections_envelope_test.go` | `TestCollectionEnvelope_HasRequiredKeys`, `TestCollectionListShape_OmitsBooks` | `collectionToABS` keys; list-shape (no `books`) vs detail-shape (with `books`) for `GET /api/collections`, `GET /api/collections/{id}`, `GET /api/libraries/{id}/collections`, and all POST/PATCH/DELETE collection endpoints |
-| `playlists_envelope_test.go` | `TestPlaylistEnvelope_HasRequiredKeys`, `TestPlaylistEnvelope_OmitsCoverPathWhenEmpty`, `TestPlaylistListShape_OmitsItems` | `playlistToABS` keys; list-shape (no `items`) vs detail-shape (with `items`); `coverPath` is omitted when `CoverItem == ""` — covers `GET /api/playlists`, `GET /api/playlists/{id}`, `GET /api/libraries/{id}/playlists`, batch and item-add/remove endpoints |
-| `smart_collections_envelope_test.go` | `TestSmartCollectionEnvelope_HasRequiredKeys`, `TestSmartCollectionEnvelope_EmptyQueryDef` | `smartCollectionToABS` keys; `queryDef` decoded from raw JSONB bytes into nested object, empty bytes → `{}` — covers `GET /api/me/smart-collections`, `GET /api/me/smart-collections/{id}`, POST/PATCH equivalents |
-| `bookmarks_envelope_test.go` | `TestBookmarkEnvelope_HasRequiredKeys` | Bookmarks emitter (separate from this cutover, not affected by migration 156) |
-| `login_envelope_test.go` | `TestLoginEnvelope_HasRequiredKeys` and three xReturnTokens / displayName variants | Login envelope (not affected by migration 156) |
-
-In addition, handler-level round-trip tests live in
-`playlists_handler_test.go` and `bookmarks_handler_test.go`. There is NO
-snapshot/goldenfile harness in the repo today — these envelope tests are
-the primary regression guard.
-
-## Manual live-DB diff procedure
-
-For a pre/post-deploy wire-shape verification against a live silo, see the
-plan's Task 5 "manual verification" section at
-`docs/superpowers/plans/2026-05-27-collections-unify-3-abs-adapters.md`
-(§ `Task 5: Wire-shape regression test`). Summary:
-
-1. Pre-cutover, seed one of each (collection, playlist with item,
-   smart collection) via the old `abs_*` tables, then capture each list
-   endpoint's response to `/tmp/wire_before_<kind>.json` using a curl
-   against the running silo with a valid ABS bearer token (HS256 JWT —
-   minted by the login flow, NOT the raw `abs_sessions.token` value).
-2. Apply migration 156. Seed equivalent rows in `user_personal_collections`
-   with the same IDs and content. Capture again to
-   `/tmp/wire_after_<kind>.json`.
-3. `diff /tmp/wire_before_<kind>.json /tmp/wire_after_<kind>.json` for each
-   `kind in {collections,playlists,smart_collections}`. Expected: empty
-   diff.
-
-This is an MR-description-level manual step, not a committed test.
-
-## Intentionally-zero fields after the rewrite
-
-These wire keys are still emitted, but the store always populates the
-in-memory field with the zero value because the canonical
-`user_personal_collections` schema has no analog column (per spec §6 of the
-collections-unify plan). They are NOT bugs — do not "fix" them by reaching
-for some other column.
-
-| In-memory field | Wire key | Zero value | Spec ref | Disposition |
-|---|---|---|---|---|
-| `abs.Playlist.CoverItem` | `coverPath` | `""` (key omitted entirely when empty — see `playlistToABS`) | spec §6.1 | Dropped. PATCH `coverPath` body field is silently ignored by the store. Cover regeneration from first-item poster is the chosen long-term path. |
-| `abs.SmartCollection.Color` | `color` | `""` (key always emitted as empty string) | spec §6.3 | Deferred. No column on `user_personal_collections`. Wire key stays present for client compatibility. |
-| `abs.SmartCollection.IsPinned` | `isPinned` | `false` (key always emitted) | spec §6.2 | Deferred. Same rationale. |
-
-If you're adding a "Pin this smart collection" feature later, the column
-needs to land in a new migration on `user_personal_collections` first;
-don't try to thread it through some adjacent column.
-
-## Canonical mapping — struct field → source column
-
-The full pre-cutover wire contract was captured in a working note that does
-not persist (`/tmp/abs_wire_contract.md`). The essentials are reproduced
-here so the next maintainer doesn't have to re-derive them.
-
-All three struct families now read from `user_personal_collections`
-(and `user_personal_collection_items` for collections + playlists),
-discriminated by `collection_type IN ('manual','playlist','smart')`.
-
-### `abs.Collection` (`collection_type = 'manual'`)
-
-| Field | Source column |
-|---|---|
-| ID | `user_personal_collections.id` |
-| UserID | `user_personal_collections.user_id::text` (column is `integer`) |
-| ProfileID | `user_personal_collections.profile_id` |
-| Name | `user_personal_collections.name` |
-| Description | `user_personal_collections.description` |
-| IsPublic | `user_personal_collections.is_shared` |
-| CreatedAt | `user_personal_collections.created_at` |
-| UpdatedAt | `user_personal_collections.updated_at` |
-
-`abs.CollectionItem` reads `user_personal_collection_items` with
-`sub_item_id = ''` filter (the manual-collection sentinel established in
-migration 156 step 1). LibraryItemID ← `media_item_id`. ORDER BY
-`added_at ASC`.
-
-### `abs.Playlist` (`collection_type = 'playlist'`)
-
-Same column mapping as `abs.Collection` (modulo `collection_type` filter)
-EXCEPT `CoverItem` which is always `""` — see "Intentionally-zero fields"
-above.
-
-`abs.PlaylistItem` reads `user_personal_collection_items` with NO
-`sub_item_id` filter (playlists can carry episode entries). Mapping:
-LibraryItemID ← `media_item_id`, EpisodeID ← `sub_item_id`,
-Position ← `position`. ORDER BY `position ASC, added_at ASC`.
-
-### `abs.SmartCollection` (`collection_type = 'smart'`)
-
-Same column mapping as `abs.Collection` EXCEPT:
-
-- `Color`, `IsPinned` → always zero (see above).
-- `QueryDef` ← `user_personal_collections.query_definition` (JSONB → `[]byte`
-  round-trip; column is `NOT NULL DEFAULT '{}'::jsonb` per migration 016).
-
-No items table — smart-collection membership is evaluated at request time
-via the `smartcoll` package.
-
-### Wire-shape quirks worth remembering
-
-- Collection/Playlist emit `lastUpdate` (NOT `updatedAt`). SmartCollection
-  emits `updatedAt`. Cross-struct inconsistency, carry forward verbatim.
-- All timestamps are `UnixMilli()` int64, NOT RFC3339 strings.
-- `ProfileID` is carried in memory but NEVER emitted on the wire — it's
-  scope/auth only.
-- The list vs detail shape distinction is implicit: list responses pass
-  `nil` for the items/books slice; the emitter then omits the key
-  entirely. Clients differentiate on key presence.
-
-## Verification status (2026-05-27)
-
-- All 13 envelope tests pass (run: `go test ./internal/audiobooks/abs/
-  -run Envelope -v -count=1`).
-- Full audiobooks test suite passes (`go test ./internal/audiobooks/...
-  -short -count=1 -timeout 120s`).
-- Live-DB diff was NOT executed in CI — see manual procedure above.

-# Audiobooks Absorption — Sub-plan 4: ABS-compat REST + Socket.io
-
-> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development. Steps use checkbox (`- [ ]`) syntax.
-
-**Goal:** Port the audiobookshelf-compatible REST + Socket.io surface from `silo-plugin-audiobooks/internal/abs/` and `silo-plugin-audiobooks/internal/abssocket/` into `internal/audiobooks/abs/` and `internal/audiobooks/abssocket/`. **Preserve the plugin's file layout** but **rewrite every SQL query** against silo's existing tables (`media_items`, `media_files`, `episodes`, `user_watch_progress`, `user_playback_sessions`, `abs_sessions`, `people`, `item_people`). No new tables.
-
-**Architecture:** Stage-based port. Support files first, then auth, then file serving, then progress, then author/series, then Socket.io, then router wiring. Out-of-scope features (bookmarks, smart collections, share links, playlists, podcasts/RSS in this sub-plan) are dropped — files containing them are not copied, or are copied with the unsupported handlers stubbed to 501 Not Implemented.
-
-**Source plugin:** `/opt/silo_plugins/silo-plugin-audiobooks/internal/{abs,abssocket}/`
-
----
-
-## Stage 1: Support files
-
-**Files to copy and adapt:**
-- `mount.go` — package mount + route registration shape
-- `handler.go` — top-level handler type + dependency wiring
-- `filter.go` — generic helpers
-- `access_log.go` — request-log helper
-- `minified.go` — generic helpers (likely small)
-
-**Adapt steps:**
-1. Replace import paths: `github.com/RXWatcher/silo-plugin-audiobooks/...` → `github.com/Silo-Server/silo-server/internal/audiobooks/...`
-2. Replace plugin SDK references with direct silo equivalents:
-   - Plugin's `*pgx.Pool` field on Handler → silo's `*pgxpool.Pool` (same type via different import alias)
-   - Plugin's `Logger` → silo's `log/slog` package-level functions
-   - Plugin's config types → struct fields on `audiobooks.Service` (extended)
-3. Remove any code that talks to the plugin SDK runtime (plugin proxy callbacks etc.)
-4. Get `go build ./internal/audiobooks/abs/...` to compile cleanly even if no routes are wired yet.
-
-Commit: `feat(audiobooks): port ABS handler scaffolding (mount/handler/filter)`.

-## Stage 2: Auth + JWT
-
-**Files:**
-- `jwt.go` — token generation + validation
-- `login_internal_test.go` (keep as test) + `login_ratelimit.go`
-- Whatever the actual `login.go` file is called (look for the login handler — likely inside `handler.go` or a dedicated file)
-
-**Adapt:**
-- The plugin's login handler posts credentials to silo's `/api/v1/auth/login` over HTTP. **In silo's in-process port, replace this HTTP round-trip with a direct call to silo's auth service** (find via `grep -nE 'auth.*Authenticate|auth.*Login' /opt/silo-server/internal/auth/*.go`). The plugin's network call is no longer needed because the code is now in-process.
-- ABS sessions are stored in `abs_sessions` (migration 139 from sub-plan 1).
-- JWT signing secret: store in `server_settings` under key `audiobooks.abs.jwt_secret` (auto-generated on first request if missing).
-
-Commit: `feat(audiobooks): port ABS auth (JWT + login bridge)`.
-
----
-
-## Stage 3: File serving + play session
-
-**Files:**
-- `file_handler.go` — handles ABS GET requests for audio file streams
-- `play_response.go` — issues a play session to the client (URL + token)
-
-**Adapt:**
-- Plugin's `bookref` lookup table (linking ABS-style IDs to backend file IDs) → use silo's `media_files.id` directly. ABS-side item ID = silo's `content_id`; ABS-side file ID = silo's `media_files.id`.
-- The stream URL ABS clients expect must point back at silo. Issue them a `/api/v1/direct-download?file_id={id}` URL signed with silo's existing media-token signer (grep `mediatoken` in `internal/`).
-
-Commit: `feat(audiobooks): port ABS file handler + play session`.
-
----
-
-## Stage 4: Progress tracking
-
-**Files:**
-- `progress_internal_test.go` (test, port)
-- Whatever file owns the `/api/me/progress` ABS endpoint family — look in `handler.go` or grep ABS progress route paths
-- `continue_listening.go`
-
-**Adapt:**
-- All progress reads/writes hit silo's `user_watch_progress` keyed on `(user_id, profile_id, content_id)`. Sub-plan 3's progress handler did this already — copy the patterns.
-
-Commit: `feat(audiobooks): port ABS progress + continue listening`.
-
----
-
-## Stage 5: Author / Series / Browse
-
-**Files:**
-- `author_series_handler.go`
-- `collapse.go`
-
-**Adapt:**
-- Author rows come from silo's `people` + `item_people` (kind=7).
-- Series grouping: if silo doesn't have an explicit "audiobook series" concept, use `media_items.title` prefix matching (e.g., books named "Foundation #1", "Foundation #2") for MVP. Document the heuristic.
-
-Commit: `feat(audiobooks): port ABS author/series browse`.
-
----
-
-## Stage 6: Socket.io
-
-**Files:**
-- `abssocket/server.go` + `abssocket/server_test.go`
-
-**Adapt:**
-- Reuse silo's `gorilla/websocket` upgrader. The plugin's standalone-listener escape hatch is no longer needed — mount under `/abs/socket.io/` on silo's main listener.
-- Redis adapter behavior preserved if `REDIS_URL` is set (silo always has one in the docker setup).
-
-Commit: `feat(audiobooks): port ABS Socket.io endpoint`.
-
----
-
-## Stage 7: Router wiring
-
-**Files:**
-- Modify `internal/api/router.go` — mount `audiobookABSHandler` under `/abs/*` and the small set of `/api/*` legacy paths ABS clients hardcode
-- Modify `internal/audiobooks/service.go` — add `ABSHandler` field, wire it from `audiobooks.New(...)`
-- Modify `cmd/silo/main.go` — construct the ABS handler and pass it into the audiobooks service
-
-**Routes to expose** (the minimum ABS-required set):
-- `POST /abs/login` (login flow)
-- `GET /abs/api/me` (profile)
-- `GET /abs/api/libraries` (library list)
-- `GET /abs/api/libraries/{id}/items` (browse)
-- `GET /abs/api/items/{id}` (item detail)
-- `GET /abs/api/items/{id}/file/{ino}` (stream)
-- `POST /abs/api/me/progress/{libraryItemId}` (progress)
-- `GET /abs/socket.io/` (Socket.io)

-For ABS-legacy hard-coded paths that don't fit under `/abs/`: register them explicitly with the ABS auth middleware so they don't collide with silo's existing `/api/v1/*`.

-- The plugin's code expects a specific database schema. Some plugin queries may have no clean silo-table equivalent (e.g., the plugin's `bookref` mapping table). In that case, stub the handler to return 501 + log + flag in PR notes — don't add new tables.
-- ABS clients have undocumented expectations (CORS headers, specific error shapes, etc.). Smoke testing against a real ABS client is the only way to find these. Defer to sub-plan 6's manual verification.
-- Each stage commits independently and produces partial functionality (e.g., after stage 2 you can log in but can't list libraries). That's intentional — clients won't connect end-to-end until stage 7.

-# Audiobook-native catalog filter fields
-
-**Status:** Draft — not yet approved or executed.
-
-**Context.** The audiobooks library page currently inherits the catalog's
-movie/TV filter set. We've already (a) wired `libraryType="audiobook[s]"`
-into the sort-relevance scope so video-only sorts (resolution, IMDb/RT
-ratings, content rating) drop out, and (b) gated the obviously-irrelevant
-video-only filter sections (Director, Writer, Producer, Studio, Network,
-Video Quality) in `CollectionGuidedRulesEditor`. What remains is
-**affirmative** support for audiobook-native filter dimensions: **author**,
-**narrator**, **series**.
-
-Commands assume the repository root is the cwd.
-
-## Goal
-
-Surface three new filter dimensions on the audiobook library page:
-
-1. **Author** — `item_people.kind = PersonKindAuthor` (7).
-2. **Narrator** — `item_people.kind = PersonKindNarrator` (8).
-3. **Series** — `audiobook_series.series_name` (free-text or distinct list).
-
-The user should be able to:
-- See per-dimension counts/options in the filter sheet (populated from the
-  current scope, like Genres/Studios already do).
-- Add a rule via the guided editor that filters items by exact author /
-  narrator / series.
-
-## Non-goals
-
-- Series **ordering** (we already have `audiobook_series.series_index`).
-  Sort by series is a separate piece of work; this plan focuses on
-  filtering only.
-- Author/narrator typeahead UI improvements beyond the existing
-  `PersonSearchSelect` (reuse it with kind-scoped lookups).
-
-## Backend
-
-### `internal/catalog/catalog_resolver.go`
-
-`CatalogFiltersResult` currently has `Genres`, `Studios`, `Networks`,
-`Countries`, `OriginalLanguages`, `ContentRatings`, `Resolutions`,
-`AudioLanguages`, `SubtitleLanguages`. Add:
-
-```go
-Authors   []string `json:"authors,omitempty"`
-Narrators []string `json:"narrators,omitempty"`
-Series    []string `json:"series,omitempty"`
-```
-
-In `listFiltersForSource`, add three parallel facet queries:
-
-- `listDistinctPeopleByKind(ctx, scope, models.PersonKindAuthor)` — joins
-  `item_people` + `people` on the result set defined by the current
-  request scope (library_ids, media_scope=audiobook, etc.) and returns
-  distinct `people.name`.
-- Same for `PersonKindNarrator`.
-- `listDistinctAudiobookSeriesNames(ctx, scope)` — distinct
-  `audiobook_series.series_name` for the scope, joined via
-  `audiobook_series.content_id = media_items.content_id`.
-
-All three need to respect the access filter the caller passes in (mirror
-how Genres/Studios already gate by access).
-
-### `internal/api/handlers/catalog.go`
-
-Extend `catalogFiltersResponse` and `HandleGetCatalogFilters` to emit the
-new fields. Mirror the pattern used for the existing ones — no flag
-gating, audiobook filters should always be included when present.
-
-### `internal/catalog/query_builder.go`
-
-Three new field names: `author`, `narrator`, `series`. The first two
-reuse `buildPersonClause` with the appropriate `PersonKind`. `series`
-needs a small new clause:
-
-```go
-case "series":
-    // EXISTS (SELECT 1 FROM audiobook_series s
-    //         WHERE s.content_id = media_items.content_id
-    //           AND lower(s.series_name) = lower($N))
-```
-
-Register the three field names in `catalogQueryRuleFields` so the parser
-accepts them. None of them are personalized — they don't go into
-`catalogPersonalRuleFields`.
-
-### Tests
-
-- `internal/catalog/catalog_resolver_test.go` — extend with audiobook
-  scope: assert authors/narrators/series come back, scoped to libraries
-  the test user has access to.
-- `internal/catalog/query_builder_test.go` — add cases for `author`,
-  `narrator`, `series` rules; verify the emitted SQL clauses match the
-  expected shape.
-
-## Frontend
-
-### `web/src/api/types.ts`
-
-Extend `CatalogFiltersResponse` (and any `ItemFiltersResponse` base, if
-shared) with optional `authors?: string[]`, `narrators?: string[]`,
-`series?: string[]`.
-
-Extend `QueryRule['field']` to include `'author' | 'narrator' | 'series'`
-if it's a literal union (or no-op if it's `string`).
-
-### `web/src/components/collections/CollectionGuidedRulesEditor.tsx`
-
-Add to `GuidedFormState`:
-- `author: string`
-- `narrator: string`
-- `series: string`
-
-Update `queryDefinitionToGuidedState` / `guidedStateToQueryDefinition` to
-round-trip the three rules (mirror how `actor` / `director` are wired).
-
-In the audiobook-only render path (already gated via `isAudiobookLibrary`),
-add a new section *above* the country row:
-
-```tsx
-<div className="grid gap-4 md:grid-cols-2">
-  <Author picker />        {/* PersonSearchSelect with kind="author" */}
-  <Narrator picker />      {/* PersonSearchSelect with kind="narrator" */}
-</div>
-<div className="grid gap-4 md:grid-cols-2">
-  <Series picker />        {/* SearchableSelect over filters.series */}
-</div>
-```
-
-`PersonSearchSelect` likely needs a new `kind` prop so it can scope its
-backend lookup to authors or narrators. If today it queries all kinds,
-we'll add a query param + handler-side filter.
-
-### `ActiveFilterBadges` + `catalogFilterBadges`
-
-Add badge rendering for the three new fields so they appear in the
-selected-filters chip row above the editor.
-
-### Tests
-
-- `web/src/components/collections/CollectionGuidedRulesEditor.test.tsx`
-  — render with `libraryType="audiobooks"` and a filters payload
-  containing authors/narrators/series; assert all three sections appear
-  and update the query definition correctly.
-
-## Migration / data
-
-No schema changes required. `PersonKindAuthor=7` and `PersonKindNarrator=8`
-already exist in `internal/models/media.go`. `audiobook_series` already
-holds series names (migration 145). The scanner is already writing both.
-
-## Risk
-
-- **Filter facet performance.** Three new distinct-value queries per
-  `/catalog/filters` request. The existing facet queries use the same
-  `facetFetcher` infrastructure, so they'll inherit the same query-time
-  budget. For an audiobook library on the order of a few thousand items
-  this should be fine; if it's not, we can cache author/narrator lookups
-  more aggressively (they change rarely).
-- **PersonSearchSelect kind scoping.** If the component today emits a
-  single combined kind=any search, we need to add kind-filtered variants
-  without breaking the existing actor/director/writer/producer pickers.
-- **Series name normalization.** Backfill at migration 145 used regex
-  parsing; some items may have inconsistent casing or whitespace.
-  Distinct facet query should `TRIM(series_name)` and present `LOWER`
-  for matching; otherwise duplicates show up in the picker.
-
-## Rollout
-
-This is gated entirely behind `libraryType === "audiobook[s]"` on the
-frontend, and the new filter fields are additive on the backend. No
-feature flag needed. Ship in two PRs if reviewer prefers:
-
-1. **Backend** — filter response fields + query-builder clauses + tests.
-2. **Frontend** — types + GuidedFormState + editor sections + tests.
-
-Or a single PR if the diff stays reviewable (~600 lines including tests).
-
-## Verification
-
-- Add new tests as above; `make lint` and `cd web && pnpm vitest run`
-  should pass.
-- Manually: open the audiobook library filter sheet, pick an author and
-  a narrator, confirm the result set narrows. Pick a series, confirm
-  same.

-# `audiobook_series` data cleanup
-
-**Status:** Draft. Findings + options; no implementation yet.
-
-## Problem
-
-Migration `145_audiobook_series.up.sql` (which created the
-`audiobook_series` table) shipped with a regex backfill that
-over-matched. On this server's 220k-book audiobook library it produced
-**162,322 distinct series names**, of which **141,591 (87%) are
-singletons** — books that are the only "member" of their named series.
-
-Spot checks make the failure mode obvious: rows like
-
-- `series_name = "Computer Programming: This Book Includes: SQL, …"` for a standalone book whose subtitle happened to contain `"#2022 Version"`
-- `series_name = "Reparación de crédito [Credit Repair]"` (the title verbatim)
-- `series_name = "Cómo Atraer a las Mujeres … [How to Attract Women …]"` (the title verbatim)
-
-The regex (`'^.+[^\s-]\s+\d+(?:\.\d+)?\s*-\s*.+$'`) treats any numeric
-chapter / edition / part token followed by ` - ` as series-N-of-book
-syntax. The real series (Star Wars, Warhammer 40k, Animorphs, Redwall,
-*In Death*, etc.) live in the 733-row "large series" bucket; the
-9,075 pairs and 10,923 small clusters mix real and false-positive.
-
-The cap added in `b95494c` keeps the user-facing dropdown manageable
-(top 1000 alphabetically), but the underlying data is still polluted —
-sorting by series, the Series filter dropdown, and any future
-"recommended" surfacing of series will all surface noise until the
-backfill is repaired.
-
-Commands assume the repository root is the cwd.
-
-## Options
-
-### A — delete singletons (destructive)
-
-```sql
-DELETE FROM audiobook_series
-WHERE series_name IN (
-  SELECT series_name FROM audiobook_series GROUP BY series_name HAVING COUNT(*) = 1
-);
-```
-
-- **Pros:** simple, removes the bulk of the noise in one shot, no
-  schema change.
-- **Cons:** also deletes legitimate "first book of a not-yet-complete
-  series" rows. Reversal requires a re-scan.
-
-### B — filter singletons at query time, leave data alone
-
-In `listDistinctAudiobookSeriesWithSource`, group by series name and
-`HAVING COUNT(*) >= 2`.
-
-- **Pros:** non-destructive; the table keeps full information for
-  detail-page lookups and series-detail surfaces.
-- **Cons:** hides legitimate one-book-only series from the filter
-  dropdown. Series-detail and sort behaviour unchanged (still surface
-  singletons). The 11.7 MB payload was already capped to 1000 in
-  `b95494c`, so the size win from this option is small.
-
-### C — mark backfill provenance, delete only backfilled singletons
-
-Add a `source` column to `audiobook_series` (`'scanner' | 'backfill'`)
-in a new migration. Migration 145's backfill rows get `source =
-'backfill'`; scanner-written rows get `'scanner'`. Then delete only the
-backfilled singletons.
-
-- **Pros:** distinguishes legitimate from spurious without guessing.
-- **Cons:** retroactive — we'd have to assume all current rows are
-  backfill (which they mostly aren't anymore — the scanner has been
-  writing too). Without a marker added at backfill time, can't tell
-  what's what.
-
-### D — wipe + re-scan (clean slate)
-
-```sql
-TRUNCATE audiobook_series;
-```
-
-Then trigger a full library re-scan so the scanner writes only the
-real series_name values it extracts from tags.
-
-- **Pros:** the cleanest end state; the scanner is authoritative.
-- **Cons:** long re-scan window (the user already noticed 219k books
-  is slow to scan); any books not currently scannable lose their
-  series info entirely. Destructive.
-
-## Recommendation
-
-**Option B as a quick win** — non-destructive, ships as a one-line SQL
-change in the facet helper, makes the Series filter dropdown useful
-immediately. The dropdown stops showing 87% noise.
-
-**Option D as the eventual fix** — once the scanner has been verified
-to write series_name authoritatively (including the series_index from
-real tags), `TRUNCATE audiobook_series` + re-scan is the right end
-state. Need to confirm scanner behaviour before pulling the trigger.
-
-Option A is too blunt (drops real first-books-of-series). Option C is
-over-engineered without a marker added at backfill time.
-
-## What this plan does not cover
-
-- Whether the scanner currently writes `audiobook_series` rows
-  authoritatively for every audiobook it touches, or only when tags
-  contain explicit series metadata. Need to check
-  `internal/scanner/audiobook.go` (or wherever the audiobook_series
-  upsert lives) before proposing option D as the long-term path.
-- Whether *Search Series* (the user-facing series-detail page, if
-  any) would also benefit from the same cleanup.
-- Sort-by-series on the library page — even with option B in place,
-  the sort still groups by every series_name including singletons,
-  so books in fake "series" appear under their fake series name.
-  Acceptable for now; revisit alongside option D.
-
-## Verification (once an option is picked)
-
-- Re-run the data sanity query in this doc's intro and confirm the
-  singleton count dropped where expected.
-- Open the Series filter dropdown on the audiobook library page and
-  confirm only multi-book series show up.
-- `go test ./internal/catalog/...` + `cd web && pnpm vitest run` still
-  pass.

-# Server-side typeahead for catalog facets
-
-**Status:** Draft. Architecture sketch; no implementation yet.
-
-## Why
-
-`b95494c` capped `/api/v1/catalog/filters` facet responses to 1000
-distinct values each, which fixed an 11.7 MB payload on the audiobook
-library (88k authors, 92k narrators, 161k series). The cap is a
-stopgap — a user looking for an author past the first 1000
-alphabetically can't find them through the dropdown.
-
-Parallel context: a separate investigation (transcript in the
-2026-05-27 sessions) compared how `librarymanagerre`, `booklore-ng`,
-and `audiobookshelf` paginate large libraries. The cursor +
-virtual-scroll camp (librarymanagerre, booklore-ng's
-`@tanstack/react-virtual`) scales to 250k+ items by never sending the
-client a full list; the eager-shelves camp (audiobookshelf web +
-mobile) renders one DOM div per item and falls over above ~30–50k.
-The 11.7 MB facet issue here is the same shape on a different surface
-— "too much data shipped to the client at once."
-
-The cleanest fix is **server-side typeahead**: the client sends a
-search prefix as the user types, the server returns the top N matches
-for that prefix.
-
-Commands assume the repository root is the cwd.
-
-## Surface
-
-### `/api/v1/catalog/filters/search`
-
-New endpoint, scoped per facet, query parameters mirror
-`/api/v1/catalog/filters` (`source`, `library_id`, etc.) plus:
-
-- `facet=author|narrator|series|studio|network|country|genre|original_language|content_rating`
-- `q=<prefix>` — the user's typed prefix (1-64 chars, trimmed)
-- `limit=<N>` — capped at e.g. 50
-
-Response:
-
-```json
-{ "matches": ["Brandon Sanderson", "Brandon Sanderson & Steven Erikson", ...], "has_more": false }
-```
-
-Returns up to `limit` matches sorted by:
-1. exact-prefix match first (`q` matches the start of the value)
-2. then case-insensitive substring match
-3. then alphabetical
-
-`has_more` is true when the underlying result set was truncated.
-
-### `/api/v1/catalog/filters` keeps the current shape
-
-No change to the existing endpoint — it still returns the capped top
-1000 per facet for the initial dropdown render. The typeahead surface
-takes over once the user starts typing.
-
-## Backend changes
-
-### `internal/catalog/catalog_resolver.go`
-
-New method `SearchFacetWithOptions(ctx, req, access, facet, prefix,
-limit)` that:
-1. Resolves the same access/scope as `ListFiltersWithOptions`.
-2. Dispatches to a facet-specific helper based on `facet`.
-3. Returns the matches + has_more flag.
-
-Add to `facetFetcher` interface:
-
-```go
-SearchPeopleByKind(ctx, kind models.PersonKind, filters BrowseFilters, baseRelation, mediaScope, prefix string, limit int) ([]string, bool, error)
-SearchAudiobookSeries(ctx, filters BrowseFilters, baseRelation, mediaScope, prefix string, limit int) ([]string, bool, error)
-SearchDistinctArrayColumn(ctx, column string, filters BrowseFilters, baseRelation, mediaScope, prefix string, limit int) ([]string, bool, error)
-SearchDistinctScalarColumn(ctx, column string, filters BrowseFilters, baseRelation, mediaScope, prefix string, limit int) ([]string, bool, error)
-```
-
-Each helper runs the existing facet SQL with an added
-`WHERE LOWER(<value>) LIKE LOWER($N || '%')` (prefix match) and
-`LIMIT N+1` (so we can detect has_more by checking if the result set
-exceeds N).
-
-### `internal/api/handlers/catalog.go`
-
-New handler `HandleCatalogFacetSearch` mounted at
-`/api/v1/catalog/filters/search`.
-
-## Frontend changes
-
-### `web/src/components/ui/searchable-select.tsx` (or a new variant)
-
-`SearchableSelect` today does client-side filtering over the full
-`options` array. Replace it for the high-cardinality facets with a
-debounced server search:
-
-- Type `<= 100ms` of inactivity → fire `/catalog/filters/search?facet=author&q=...`
-- Reset focus + cancel in-flight when the user keeps typing
-- Show the first 50 matches; "show more" disabled (the user types more
-  to narrow further)
-
-The existing `SearchableSelect` stays for low-cardinality facets
-(genres, content_ratings, etc.) where the initial 1000 is plenty.
-
-### `web/src/components/collections/CollectionGuidedRulesEditor.tsx`
-
-Author / Narrator / Series sections switch to the new typeahead-backed
-select. Studio / Network / Country can stay on `SearchableSelect`
-(low-cardinality) or migrate later for consistency.
-
-## Tests
-
-- Backend: search SQL emits the LIKE prefix + LIMIT N+1, has_more
-  semantics, access filter still gates the result set.
-- Frontend: typeahead component debounces, cancels stale requests,
-  renders empty / loading / no-results states.
-
-## Migration
-
-None — additive endpoint. Frontend can be rolled out incrementally:
-audiobook-only sections first (since they're the worst offenders),
-others later.
-
-## What this plan does not cover
-
-- The audiobookshelf-app pagination question from the separate
-  transcript. That's a different surface (the ABS-compat
-  `/abs/api/libraries/{id}/items` endpoint on `:13378`), not the silo
-  native catalog. Same architectural family but the patch lives in
-  `internal/audiobooks/abs/libraries_handler.go`, not catalog.
-- A general client-side virtual scroll for the library grid itself.
-  That's the cousin problem ("250k books rendered as 125k shelf
-  divs"); cross-applies but is its own work.
-
-## Risk / rollout
-
-- New endpoint is opt-in for the frontend — existing callers keep
-  using the bulk `/filters` response.
-- Typeahead latency budget: each keystroke fires one DB query against
-  the same indexes the bulk facets already use. Should be fast
-  (`item_people(content_id, kind)` covers people lookups,
-  `audiobook_series(content_id)` covers series, and a `LOWER()`
-  functional index already exists on
-  `audiobook_series_name_lower`). Verify with EXPLAIN before shipping.

-Run: `go build ./...`
-Expected: clean (the embed package compiles fine even if a new file is added).
-
-- [ ] **Step 3: Commit (up only — down comes next task)**
-
-Don't commit yet. Commit happens after Task 2's down-migration so the up/down pair lands atomically.
-
----
-
-## Task 2: Down-migration body
-
-**Files:**
-- Create: `migrations/156_unify_user_collections.down.sql`
-
-The down migration is intentionally lossy in reverse: rolling back loses any `'playlist'`/`'smart'` collections that were created after the up. With the up bringing in 1 row, lossy reverse is acceptable.
-
-- [ ] **Step 1: Find the abs_* CREATE TABLE statements to inline**
-
-Read these files and copy their `CREATE TABLE` bodies (and `CREATE INDEX` statements; **omit** any `DROP TABLE IF EXISTS` boilerplate at the top — the down migration creates from clean state):
-
-```bash
-cat migrations/149_abs_user_collections.up.sql
-cat migrations/150_abs_collection_items.up.sql
-cat migrations/151_abs_playlists.up.sql
-cat migrations/152_abs_playlist_items.up.sql
-cat migrations/153_abs_smart_collections.up.sql
-```
-
-- [ ] **Step 2: Write the down migration**
-
-```sql
--- Reverse migration 156. Lossy in reverse — playlist/smart rows
--- created after the up migration are deleted, not migrated back.
-
--- 1. Remove the page_sections column.
-ALTER TABLE page_sections DROP COLUMN media_types;
-
--- 2. Recreate the abs_* tables empty. Schemas are inlined from the
---    original up migrations 149–153 — keep identical (column types,
---    constraint names, index names) so any tool keyed off those names
---    sees the same shape.
---
--- BEGIN inlined from migrations/149_abs_user_collections.up.sql
---   <PASTE EXACT CREATE TABLE + CREATE INDEX statements>
--- END inlined
-
--- BEGIN inlined from migrations/150_abs_collection_items.up.sql
---   <PASTE EXACT CREATE TABLE + CREATE INDEX statements>
--- END inlined
-
--- BEGIN inlined from migrations/151_abs_playlists.up.sql
---   <PASTE EXACT CREATE TABLE + CREATE INDEX + FK statements>
--- END inlined
-
--- BEGIN inlined from migrations/152_abs_playlist_items.up.sql
---   <PASTE EXACT CREATE TABLE + CREATE INDEX + FK statements>
--- END inlined
-
--- BEGIN inlined from migrations/153_abs_smart_collections.up.sql
---   <PASTE EXACT CREATE TABLE + CREATE INDEX statements>
--- END inlined
-
--- 3. Remove rows we promoted from abs_playlists during the up.
-DELETE FROM user_personal_collection_items
-    WHERE collection_id IN (
-        SELECT id FROM user_personal_collections
-        WHERE collection_type IN ('playlist', 'smart')
-    );
-DELETE FROM user_personal_collections
-    WHERE collection_type IN ('playlist', 'smart');
-
--- 4. Restore the narrow CHECK constraint.
-ALTER TABLE user_personal_collections
-    DROP CONSTRAINT IF EXISTS user_personal_collections_type_check;
-ALTER TABLE user_personal_collections
-    ADD CONSTRAINT user_personal_collections_type_check
-    CHECK (collection_type IN ('manual', 'synced'));
-
--- 5. Drop the sub_item_id column.
-ALTER TABLE user_personal_collection_items DROP COLUMN sub_item_id;
-```
-
-Replace each `<PASTE EXACT ... statements>` block with the actual SQL from the corresponding `migrations/14X_abs_*.up.sql` file. Do NOT skip any constraint or index — the round-trip test below verifies parity.
-
-- [ ] **Step 3: Verify SQL syntactic validity**
-
-Run: `go build ./...`
-Expected: clean.
-
-- [ ] **Step 4: Commit the up+down pair**
-
-```bash
-git add migrations/156_unify_user_collections.up.sql migrations/156_unify_user_collections.down.sql
-git commit -m "feat(migrations): 156 unify user collections
-
-Adds sub_item_id to user_personal_collection_items, widens
-collection_type to include 'playlist' and 'smart', adds media_types
-filter to page_sections, moves the existing abs_playlists row into
-the canonical store, and drops the abs_* collection tables.
-
-Lays the storage foundation for sub-projects 2-4 to wire the
-application against."
-```
-
----
-
-## Task 3: Migration round-trip test
-
-**Files:**
-- Create: `migrations/156_unify_user_collections_test.go` (only if a similar pattern exists in the repo)
-
-The repo doesn't have a standard "migration round-trip test" harness today (verify with `find . -name "migration*_test.go" -o -name "*round_trip*_test.go" | head`). If no harness exists, this task is **best-effort manual verification**:
-
-- [ ] **Step 1: Verify a harness pattern exists, or skip to manual verification**
-
-Run:
-```bash
-find . -name "migration*_test.go" -not -path "*/node_modules/*" 2>/dev/null | head
-grep -rln "migrate.Up\|migrate.Down\|migrate.Steps" --include="*_test.go" 2>/dev/null | head
-```
-
-If no harness emerges, fall through to Step 2 (manual). Otherwise add a Go test following the existing harness pattern that:
-1. Migrates to 155.
-2. Inserts a fake `abs_playlists` row (id `test-pl-1`, user 1, name `test`).
-3. Inserts a fake `abs_playlist_items` row referencing it.
-4. Migrates up to 156.
-5. Asserts `user_personal_collections WHERE collection_type='playlist' AND id='test-pl-1'` exists and `user_personal_collection_items WHERE collection_id='test-pl-1'` exists.
-6. Migrates down to 155.
-7. Asserts the `abs_playlists` table exists and is empty (the row is GONE — down is lossy by design).
-
-- [ ] **Step 2: Manual verification against a throwaway DB**
-
-If no harness, do the following manually once and capture the output in the MR description:
-
-```bash
-# 1. Spin up an empty postgres
-docker run --rm -d --name pgcheck -e POSTGRES_PASSWORD=x -p 5443:5432 pgvector/pgvector:pg18
-sleep 5
-
-# 2. Apply migrations up to 155 (use the existing migrate binary or schema dump)
-#    Adapt this to whatever the repo uses to run migrations against an arbitrary DB.
-
-# 3. Insert a fake abs_playlists + items row.
-PGPASSWORD=x psql -h localhost -p 5443 -U postgres -d postgres -c "
-    INSERT INTO abs_playlists(id, user_id, name) VALUES ('test-pl-1', 1, 'test');
-    INSERT INTO abs_playlist_items(playlist_id, library_item_id, position) VALUES ('test-pl-1', 'foo', 0);
-"
-
-# 4. Apply migration 156.
-# 5. Verify the row landed in user_personal_collections.
-PGPASSWORD=x psql -h localhost -p 5443 -U postgres -d postgres -c "
-    SELECT collection_type, name FROM user_personal_collections WHERE id='test-pl-1';
-    SELECT collection_id, media_item_id, sub_item_id FROM user_personal_collection_items WHERE collection_id='test-pl-1';
-"
-# Expected: collection_type='playlist', name='test'; one item row with sub_item_id=''
-
-# 6. Apply down migration.
-# 7. Verify abs_playlists exists (empty) and user_personal_collections has no playlist rows.
-
-# Cleanup
-docker rm -f pgcheck
-```
-
-- [ ] **Step 3: If you added a Go test, commit it**
-
-```bash
-git add migrations/156_unify_user_collections_test.go
-git commit -m "test(migrations): 156 round-trip verifies abs_playlists migrate to canonical"
-```
-
-If only manual verification was done, capture the output in the MR description instead — no commit needed.
-
----
-
-## Verification (after merge)
-
-1. **Dev DB** — run `make dev-backend` against a fresh DB. Migration 156 applies cleanly. `\d user_personal_collection_items` shows the `sub_item_id` column. `\d page_sections` shows `media_types`.
-
-2. **Existing data migration** — on a copy of the production DB (or staging if available), run migration 156 and verify the single existing `abs_playlists` row is now in `user_personal_collections` with `collection_type='playlist'`:
-
-   ```sql
-   SELECT id, name, collection_type FROM user_personal_collections WHERE collection_type='playlist';
-   ```
-
-3. **abs_* tables gone** — confirm:
-
-   ```sql
-   SELECT table_name FROM information_schema.tables WHERE table_schema='public' AND table_name LIKE 'abs_%collection%';
-   -- Should return 0 rows.
-   ```
-
-   `abs_sessions`, `abs_bookmarks`, `abs_playback_sessions`, `abs_rss_feeds` remain — those aren't in scope here.
-
-4. **Silo binary builds against the new schema** — `go build ./...` is green even though the ABS store adapters still reference the dropped tables. They reference them via SQL strings, so compile-time is fine; runtime will fail until sub-project 3 rewrites them. **Do NOT** deploy without sub-project 3, or stash this migration behind a feature flag.
-
----
-
-## Self-Review
-
-**Spec coverage:**
-- `sub_item_id` column ✓ (Task 1)
-- `collection_type` widened to playlist/smart ✓ (Task 1)
-- Move existing abs_playlists row ✓ (Task 1)
-- Drop abs_* tables ✓ (Task 1)
-- `page_sections.media_types` ✓ (Task 1)
-- Down migration ✓ (Task 2)
-- Round-trip test ✓ (Task 3, best-effort)
-
-**Placeholder scan:** The `<PASTE EXACT ... statements>` blocks in Task 2 Step 2 are template placeholders that the implementer must fill in by copying from the existing migration files. Each is bounded by explicit BEGIN/END comment markers naming the source file. The instructions in Step 1 say to read those files first; Step 2's block then becomes literal SQL. Not a "TBD" in the bad sense — it's a deliberate copy-from-source step.
-
-**Type consistency:** `sub_item_id` (text, NOT NULL DEFAULT '') consistent in up + down + verification queries. `collection_type` enum values consistent across the spec, up, down, and CHECK constraint.
-
-**Risk:** All schema-level, no application changes. The biggest risk is forgetting to ship sub-project 3 in the same release — runtime will start erroring on ABS endpoints the moment migration 156 applies, because the adapters still query the dropped tables.

-# Collections Unification — Sub-project 2: Smartcoll Engine Lift
-
-> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
-
-**Goal:** Move the smart-collection rule engine from `internal/audiobooks/smartcoll/` to `internal/smartcoll/` so all media types (movie, series, audiobook) share one evaluator. Pure code move + import update; no logic changes.
-
-**Architecture:** The 4-file package (~1060 LOC) currently lives in `internal/audiobooks/smartcoll/`. We relocate it verbatim and rewire its imports. The existing in-place audiobook caller (`internal/audiobooks/abs_smart_collection_store.go`) updates its import path. Sub-projects 3 and 4 will later call the engine from new sites (ABS adapter rewrites, section recipes); those plans cover their own wiring.
-
-**Tech Stack:** Go. Standard `gopls`-style refactor: move, fix imports, run tests.
-
-**Commands assume the repository root is the cwd.**
-
-**Source spec:** `docs/superpowers/specs/2026-05-27-unified-audiobook-collections-design.md` §4.2, §4.6.
-
-**Predecessor sub-project:** None — this lands independent of sub-project 1. Order doesn't matter.
-
----
-
-## File map
-
-**Move (4 files):**
-- `internal/audiobooks/smartcoll/evaluator.go` → `internal/smartcoll/evaluator.go`
-- `internal/audiobooks/smartcoll/evaluator_test.go` → `internal/smartcoll/evaluator_test.go`
-- `internal/audiobooks/smartcoll/query.go` → `internal/smartcoll/query.go`
-- `internal/audiobooks/smartcoll/query_test.go` → `internal/smartcoll/query_test.go`
-
-**Modify (import path):**
-- Every file that imports `github.com/Silo-Server/silo-server/internal/audiobooks/smartcoll` — change to `github.com/Silo-Server/silo-server/internal/smartcoll`.
-
-**Add (new test, cross-type coverage):**
-- `internal/smartcoll/cross_type_test.go` — three tests verifying audiobook-specific rules no-op against non-audiobook items.
-
----
-
-## Task 1: Move the package directory
-
-**Files:** see "Move" list above.
-
-- [ ] **Step 1: Pre-check current contents**
-
-```bash
-ls internal/audiobooks/smartcoll/
-wc -l internal/audiobooks/smartcoll/*.go
-```
-
-Expected: 4 files (evaluator.go, evaluator_test.go, query.go, query_test.go). If the contents differ, pause and report — the plan assumes this exact set.
-
-- [ ] **Step 2: Verify nothing outside the package references it (yet) besides the known caller**
-
-```bash
-grep -rln '"github.com/Silo-Server/silo-server/internal/audiobooks/smartcoll"' --include="*.go" .
-```
-
-Expected: `internal/audiobooks/abs_smart_collection_store.go` and possibly its test, plus the package's own test files. If you find any other importer, pause and add it to the import-update list in Task 2.
-
-- [ ] **Step 3: Create the new directory and move the files**
-
-```bash
-mkdir -p internal/smartcoll
-git mv internal/audiobooks/smartcoll/evaluator.go      internal/smartcoll/evaluator.go
-git mv internal/audiobooks/smartcoll/evaluator_test.go internal/smartcoll/evaluator_test.go
-git mv internal/audiobooks/smartcoll/query.go          internal/smartcoll/query.go
-git mv internal/audiobooks/smartcoll/query_test.go     internal/smartcoll/query_test.go
-rmdir internal/audiobooks/smartcoll
-```
-
-`git mv` preserves blame history.
-
-- [ ] **Step 4: Update the package declaration in each moved file**
-
-The package name was `smartcoll`; it stays `smartcoll`. Open each moved file and **verify** the `package smartcoll` line is unchanged. If any file declares `package audiobooks_smartcoll` or similar, fix it to `package smartcoll`.
-
-```bash
-head -1 internal/smartcoll/*.go
-```
-
-Expected: every line reads `package smartcoll`. If any differ, fix with sed:
-
-```bash
-sed -i '1s/^package .*/package smartcoll/' internal/smartcoll/<filename>.go
-```
-
-- [ ] **Step 5: Build — this WILL fail until Task 2 runs**
-
-```bash
-go build ./...
-```
-
-Expected: compilation error in `internal/audiobooks/abs_smart_collection_store.go` because its import path now points at a non-existent directory. That's expected — Task 2 fixes it. **Do not commit yet.**
-
----
-
-## Task 2: Update all imports
-
-**Files:**
-- Modify: every file from Task 1 Step 2's grep result.
-
-- [ ] **Step 1: Update each importer**
-
-The typical pattern in the existing caller is:
-
-```go
-import (
-    // ...
-    "github.com/Silo-Server/silo-server/internal/audiobooks/smartcoll"
-)
-```
-
-Becomes:
-
-```go
-import (
-    // ...
-    "github.com/Silo-Server/silo-server/internal/smartcoll"
-)
-```
-
-For each file in the Task 1 Step 2 grep result, run:
-
-```bash
-sed -i 's|"github.com/Silo-Server/silo-server/internal/audiobooks/smartcoll"|"github.com/Silo-Server/silo-server/internal/smartcoll"|' <file>
-```
-
-Or edit by hand using your editor's find-and-replace.
-
-- [ ] **Step 2: Verify no stale import remains**
-
-```bash
-grep -rln '"github.com/Silo-Server/silo-server/internal/audiobooks/smartcoll"' --include="*.go" . || echo "clean"
-```
-
-Expected: `clean` (no matches).
-
-- [ ] **Step 3: Build + test**
-
-```bash
-go build ./...
-go test ./internal/smartcoll/ ./internal/audiobooks/... -short -timeout 60s
-go vet ./internal/smartcoll/ ./internal/audiobooks/...
-```
-
-Expected: all green. The moved tests still pass because the engine logic is unchanged; the package path changed but the test code itself is package-local.
-
-- [ ] **Step 4: Commit the move + import fix**
-
-```bash
-git add internal/smartcoll/ internal/audiobooks/
-git commit -m "refactor(smartcoll): lift engine to internal/smartcoll
-
-Moves the smart-collection rule engine out of internal/audiobooks/
-so movie/TV smart collections can share the same evaluator.
-
-No logic changes. Tests move with their package and continue to pass."
-```
-
-`git log --follow internal/smartcoll/evaluator.go` should show the prior history at the old path.
-
----
-
-## Task 3: Cross-type smoke tests
-
-**Files:**
-- Create: `internal/smartcoll/cross_type_test.go`
-
-The existing tests cover audiobook-specific rule evaluation. Sub-project 4 will start asking the engine to evaluate against movies + TV, so we add three small tests that nail down the no-op contract for audiobook-specific predicates against non-audiobook items.
-
-- [ ] **Step 1: Find the audiobook-specific rule kinds**
-
-```bash
-grep -nE 'narrator|series_position|"type":"audiobook"' internal/smartcoll/query.go | head -10
-```
-
-Expected: rule-kind constants named like `RuleKindNarrator`, `RuleKindSeriesPosition`, or similar. Note the exact names — the test below references them. **If the rule kinds are not actually present (rule registration happens elsewhere), pause and report — the spec assumed they exist.**
-
-- [ ] **Step 2: Read the existing query/evaluator test fixtures**
-
-```bash
-sed -n '/func Test/,/^func /p' internal/smartcoll/evaluator_test.go | head -60
-```
-
-Note the harness pattern used (how an evaluator is constructed in tests, how it's given items, how match-results are asserted). Mirror that pattern in the new tests.
-
-- [ ] **Step 3: Write the failing tests**
-
-Create `internal/smartcoll/cross_type_test.go`:
-
-```go
-package smartcoll
-
-import (
-	"testing"
-
-	"github.com/Silo-Server/silo-server/internal/models"
-)
-
-// TestNarratorRuleNoopOnMovie verifies that an audiobook-specific narrator
-// rule treats movie items as a no-op (matches everything, since the rule
-// can't apply). This is the cross-type contract that lets the engine
-// evaluate against mixed-type item sets without errors.
-func TestNarratorRuleNoopOnMovie(t *testing.T) {
-	// Adapt to the actual evaluator-construction API discovered in Step 2.
-	// Expected: build an evaluator with a narrator-name predicate, evaluate
-	// it against a movie item, assert no error AND the item is matched
-	// (or excluded — pick whichever the existing audiobook tests treat as
-	// "no-op" and document it).
-	t.Skip("Implement once the evaluator API is read from existing tests")
-}
-
-// TestSeriesPositionRuleNoopOnSeries verifies the audiobook series_position
-// rule has no effect on a TV series item (which has its own series concept,
-// distinct from book series).
-func TestSeriesPositionRuleNoopOnSeries(t *testing.T) {
-	t.Skip("Implement once the evaluator API is read from existing tests")
-}
-
-// TestLibraryIdFilterAppliesToAllTypes verifies that the simple library_id
-// predicate (the silo-native query_definition subset) evaluates correctly
-// against any media type. This locks in compat with existing
-// user_personal_collections rows after migration 156.
-func TestLibraryIdFilterAppliesToAllTypes(t *testing.T) {
-	t.Skip("Implement once the evaluator API is read from existing tests")
-}
-
-var _ = models.MediaItem{} // import-stability marker; remove once tests are real
-```
-
-- [ ] **Step 4: Fill in the test bodies**
-
-Replace each `t.Skip(...)` with a real test using the harness pattern from the existing tests. The exact code depends on the evaluator's public surface (constructor, evaluate method, predicate registration). **Read `internal/smartcoll/evaluator.go` and the existing test file once before writing the bodies** — don't guess at the API.
-
-If the evaluator's no-op behavior for type-mismatched rules turns out to be "exclude the item" rather than "match the item", adjust the assertions to reflect that — but document the chosen semantic in a comment above each test so future readers know which it is.
-
-- [ ] **Step 5: Run the new tests**
-
-```bash
-go test ./internal/smartcoll/ -run "Cross|Noop|LibraryIdFilter" -v
-```
-
-Expected: all three PASS, and the existing tests in the package continue to pass.
-
-- [ ] **Step 6: Commit**
-
-```bash
-git add internal/smartcoll/cross_type_test.go
-git commit -m "test(smartcoll): cross-type evaluator contract
-
-Locks in the no-op semantics for audiobook-specific rules evaluated
-against non-audiobook items, plus library_id filter compat across
-all types."
-```
-
----
-
-## Verification (after merge)
-
-1. `git log --follow internal/smartcoll/evaluator.go` shows the prior history at `internal/audiobooks/smartcoll/evaluator.go` — confirms blame preserved.
-2. `go test ./internal/smartcoll/ -v` runs both the moved tests and the three new cross-type tests, all passing.
-3. `grep -rln 'internal/audiobooks/smartcoll' --include="*.go" .` returns empty.
-4. No production behavior change. Smart collections in the ABS API still resolve via the engine; the engine just lives at a new path.
-
----
-
-## Self-Review
-
-**Spec coverage:**
-- Move package to `internal/smartcoll/` ✓ (Task 1)
-- Update import paths ✓ (Task 2)
-- Cross-type evaluator tests ✓ (Task 3)
-
-**Placeholder scan:** Task 3's `t.Skip(...)` lines are explicit failing-test stubs that Step 4 fills in. The instructions in Step 4 say to read the existing tests first rather than guess. Not a TBD — it's a "read-existing, then write" workflow with explicit guidance.
-
-**Type consistency:** Package name `smartcoll` consistent. Import path `github.com/Silo-Server/silo-server/internal/smartcoll` consistent. Rule-kind names depend on what Step 1 of Task 3 discovers — the plan flags this explicitly.
-
-**Risk:** Pure refactor. The chance of breakage is low (Go's import system catches missed renames at compile time). The cross-type tests are new functionality, but they assert behavior that already exists in the engine (no-op on type-mismatch) so they should pass without code changes.

-# Collections Unification — Sub-project 3: ABS Store Adapter Rewrites
-
-> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
-
-**Goal:** Rewrite the three ABS store adapters (`abs_collection_store.go`, `abs_playlist_store.go`, `abs_smart_collection_store.go`) to query the canonical `user_personal_collections` tables instead of the dropped `abs_*` tables. The wire shape returned by ABS HTTP endpoints must remain byte-identical so the ABS Android/iOS apps don't notice anything changed.
-
-**Architecture:** The three adapter files expose a struct + ~6 methods each (List, Get, Create, Update, Delete, ListItems, AddItem, RemoveItem) consumed by `internal/audiobooks/abs/` HTTP handlers. We keep every public method signature unchanged and replace each SQL body with one that maps to `user_personal_collections` filtered by `collection_type`. Granular podcast-episode entries map to the new `sub_item_id` column. Library scoping (which library this list "belongs to" in ABS UI) is stored in `query_definition.library_ids`.
-
-**Tech Stack:** Go, `pgx/v5`, `database/sql`-style query patterns from the existing adapters.
-
-**Commands assume the repository root is the cwd.**
-
-**Source spec:** `docs/superpowers/specs/2026-05-27-unified-audiobook-collections-design.md` §4.3, §4.5.
-
-**Predecessor sub-projects:**
-- Sub-project 1 (migration 156) **must** land before this. The new tables/columns are required.
-- Sub-project 2 (smartcoll lift) needed only for the smart-collection adapter — if 2 hasn't landed, Task 3 below can either wait for it or temporarily keep the old import path.
-
----
-
-## File map
-
-**Modify (rewrite bodies, keep method signatures):**
-- `internal/audiobooks/abs_collection_store.go` (193 lines today; ~8 methods)
-- `internal/audiobooks/abs_playlist_store.go` (210 lines today; ~9 methods including `coverArg`)
-- `internal/audiobooks/abs_smart_collection_store.go` (~140 lines today; ~6 methods)
-
-**Add (snapshot tests for wire-shape preservation):**
-- `internal/audiobooks/abs_collection_store_test.go` (if not already present — check first)
-- `internal/audiobooks/abs_playlist_store_test.go`
-- `internal/audiobooks/abs_smart_collection_store_test.go`
-
-**No new files** beyond those three test files. No new exported types.
-
----
-
-## Task 1: Capture pre-cutover wire shapes (snapshots)
-
-This task runs against the **pre-migration** ABS endpoints. Capture JSON now so we can diff after.
-
-**Files:** none modified; output captured to `/tmp/abs_wire_*.json`.
-
-- [ ] **Step 1: Identify the wire-shape contract**
-
-The ABS HTTP handlers live in `internal/audiobooks/abs/`. They call the store adapters, which return Go structs. The structs (`abs.Collection`, `abs.Playlist`, `abs.SmartCollection`, etc.) marshal to JSON via standard struct tags. The wire shape is fixed by those struct tag declarations.
-
-Read them:
-
-```bash
-grep -n "type Collection struct\|type Playlist struct\|type SmartCollection struct\|type CollectionItem struct\|type PlaylistItem struct" internal/audiobooks/abs/*.go
-```
-
-For each struct, note every field's JSON tag. **This is your reference contract.** The rewritten store must populate every field with the same semantic content as today.
-
-- [ ] **Step 2: Capture sample JSON from existing endpoints (if any data exists)**
-
-The DB today has 1 abs_playlists row, 0 collections, 0 smart collections. Even one sample helps. Hit each endpoint via `curl` against the running silo and save the output:
-
-```bash
-# Adapt to your env's auth / port
-PORT=8090   # silo's API port from .env
-TOKEN=...   # admin or user JWT
-
-curl -sH "Authorization: Bearer $TOKEN" http://localhost:$PORT/api/libraries/9/collections \
-    > /tmp/abs_wire_collections.json

-If you don't have a token or the data is uninteresting (empty arrays), skip this step — the field-by-field reference from Step 1 is enough to write correct code.
-
-- [ ] **Step 3: Note any non-obvious mappings**
-
-For each adapter, write out the mapping between abs.* struct fields and `user_personal_collections` columns. Sample for Collection:
-
-| `abs.Collection` field | Source column |
-|---|---|
-| `Id` | `user_personal_collections.id` |
-| `Name` | `user_personal_collections.name` |
-| `Description` | `user_personal_collections.description` |
-| `UserId` | `user_personal_collections.user_id` |
-| `LibraryId` | derived from `query_definition.library_ids[0]` (single library scope per collection) |
-| `IsPublic` | `user_personal_collections.is_shared` |
-| `CreatedAt` / `UpdatedAt` | timestamps as-is |
-
-Similar table for Playlist and SmartCollection. **Write this out in a working note** — you'll reference it in Task 2.
-
-No commit for this task.

-## Task 2: Rewrite `ABSCollectionStore`
-
-**Files:**
-- Modify: `internal/audiobooks/abs_collection_store.go`
-- Test: `internal/audiobooks/abs_collection_store_test.go` (create if missing)
-
-The current 8 methods are: `ListUserCollections`, `GetCollection`, `CreateCollection`, `UpdateCollection`, `DeleteCollection`, `ListCollectionItems`, `AddCollectionItem`, `RemoveCollectionItem`.
-
-For each, the rewrite swaps `FROM abs_user_collections` / `FROM abs_collection_items` for the canonical equivalents.
-
-- [ ] **Step 1: Write a failing test for `ListUserCollections`**
-
-Append to `internal/audiobooks/abs_collection_store_test.go` (create the file if absent, declaring `package audiobooks`):
-
-```go
-package audiobooks
-
-import (
-	"context"
-	"testing"
-	// ...add the test DB harness import discovered by the next step
-)
-
-func TestABSCollectionStoreListUserCollections(t *testing.T) {
-	if testing.Short() {
-		t.Skip("requires test DB")
-	}
-	ctx := context.Background()
-	// Set up a test pool against migration head (>= 156).
-	pool := newTestPool(t)
-	defer pool.Close()
-
-	// Insert one user_personal_collections row with collection_type='manual',
-	// is_shared=true, library_ids=[9] in query_definition.
-	_, err := pool.Exec(ctx, `
-		INSERT INTO user_personal_collections
-			(id, user_id, profile_id, name, description, collection_type,
-			 is_shared, created_at, updated_at, creator_profile_id, query_definition)
-		VALUES
-			('test-c-1', 1, '', 'TestColl', 'desc', 'manual',
-			 true, NOW(), NOW(), '', '{"library_ids":[9]}'::jsonb)
-	`)
-	if err != nil {
-		t.Fatalf("seed: %v", err)
-	}
-
-	store := &ABSCollectionStore{pool: pool}
-	got, err := store.ListUserCollections(ctx, "1", "")
-	if err != nil {
-		t.Fatalf("ListUserCollections: %v", err)
-	}
-	if len(got) != 1 {
-		t.Fatalf("got %d collections, want 1", len(got))
-	}
-	if got[0].Id != "test-c-1" || got[0].Name != "TestColl" || !got[0].IsPublic {
-		t.Errorf("unexpected fields: %+v", got[0])
-	}
-}
-```
-
-**Verify the test-pool harness:** `grep -rln "func newTestPool\|func testPool" --include="*_test.go" .` finds the project's convention. If none exists, this test stays gated by `testing.Short()` and is best-effort — flag in the PR.
-
-- [ ] **Step 2: Run the test to verify it fails**
-
-```bash
-go test ./internal/audiobooks/ -run TestABSCollectionStoreListUserCollections -v
-```
-
-Expected: FAIL because `ListUserCollections` still queries the dropped `abs_user_collections` table.
-
-- [ ] **Step 3: Rewrite `ListUserCollections`**
-
-Replace the existing function body with:
-
-```go
-func (s *ABSCollectionStore) ListUserCollections(ctx context.Context, userID, profileID string) ([]abs.Collection, error) {
-	const q = `
-		SELECT
-			id, name, description, COALESCE(query_definition->'library_ids'->>0, '0')::int AS library_id,
-			user_id, is_shared, created_at, updated_at
-		FROM user_personal_collections
-		WHERE collection_type = 'manual'
-		  AND user_id = $1::int
-		  AND (profile_id = $2 OR ($2 = '' AND profile_id = ''))
-		ORDER BY created_at DESC
-	`
-	rows, err := s.pool.Query(ctx, q, userID, profileID)
-	if err != nil {
-		return nil, fmt.Errorf("abs collection list: %w", err)
-	}
-	defer rows.Close()
-
-	var out []abs.Collection
-	for rows.Next() {
-		var c abs.Collection
-		if err := rows.Scan(&c.Id, &c.Name, &c.Description, &c.LibraryId, &c.UserId, &c.IsPublic, &c.CreatedAt, &c.UpdatedAt); err != nil {
-			return nil, fmt.Errorf("scan abs collection: %w", err)
-		}
-		out = append(out, c)
-	}
-	return out, rows.Err()
-}
-```
-
-Adjust the `Scan` order to match `abs.Collection`'s actual field types — read the struct from `internal/audiobooks/abs/` to confirm. If `Id` is named `ID` per Go convention, fix accordingly.
-
-- [ ] **Step 4: Run the test, verify it passes**
-
-```bash
-go test ./internal/audiobooks/ -run TestABSCollectionStoreListUserCollections -v
-```
-
-Expected: PASS.
-
-- [ ] **Step 5: Rewrite the remaining 7 methods using the same pattern**
-
-For each method, apply this template:
-
-| Method | Canonical operation |
-|---|---|
-| `GetCollection(id)` | `SELECT … WHERE id=$1 AND collection_type='manual'` |
-| `CreateCollection(c)` | `INSERT INTO user_personal_collections (...) VALUES (..., 'manual', ..., jsonb_build_object('library_ids', jsonb_build_array(c.LibraryId)))` |
-| `UpdateCollection(c)` | `UPDATE user_personal_collections SET name=$2, description=$3, is_shared=$4, query_definition=$5, updated_at=NOW() WHERE id=$1 AND collection_type='manual'` |
-| `DeleteCollection(id)` | `DELETE FROM user_personal_collections WHERE id=$1 AND collection_type='manual'` (cascades to items via the existing FK) |
-| `ListCollectionItems(collectionID)` | `SELECT media_item_id, sub_item_id, position FROM user_personal_collection_items WHERE collection_id=$1 ORDER BY position, added_at` — map `media_item_id`→`abs.CollectionItem.LibraryItemId`, `sub_item_id`→`abs.CollectionItem.EpisodeId` |
-| `AddCollectionItem(collectionID, libraryItemID)` | `INSERT INTO user_personal_collection_items (user_id, collection_id, media_item_id, sub_item_id, position, added_at) SELECT user_id, $1, $2, '', COALESCE(MAX(position)+1, 0), NOW() FROM user_personal_collections c LEFT JOIN user_personal_collection_items i ON i.collection_id = c.id WHERE c.id=$1 GROUP BY user_id` |
-| `RemoveCollectionItem(collectionID, libraryItemID)` | `DELETE FROM user_personal_collection_items WHERE collection_id=$1 AND media_item_id=$2 AND sub_item_id=''` |
-
-Each gets its own targeted test mirroring Step 1's structure: insert seed data, call the method, assert the canonical-table side-effect (`SELECT … FROM user_personal_collection_items …`).
-
-For brevity, the plan shows the SQL above as a table; the actual implementation has each method as a complete function. Reuse the connection-error-wrapping style and the `fmt.Errorf("...: %w", err)` pattern already in the file.
-
-- [ ] **Step 6: Run all tests for the file**
-
-```bash
-go test ./internal/audiobooks/ -run TestABSCollectionStore -v
-```
-
-Expected: all PASS.
-
-- [ ] **Step 7: Commit**
-
-```bash
-git add internal/audiobooks/abs_collection_store.go internal/audiobooks/abs_collection_store_test.go
-git commit -m "refactor(audiobooks): ABS collection store queries canonical tables
-
-Rewrites ABSCollectionStore's 8 methods to read/write
-user_personal_collections (collection_type='manual') instead of the
-dropped abs_user_collections / abs_collection_items tables. Library
-scope is now encoded in query_definition.library_ids.
-
-ABS HTTP handlers consume the same method signatures; wire shape
-is unchanged."

-## Task 3: Rewrite `ABSPlaylistStore`
-
-**Files:**
-- Modify: `internal/audiobooks/abs_playlist_store.go`
-- Test: `internal/audiobooks/abs_playlist_store_test.go` (create if missing)
-
-Same pattern as Task 2. Methods: `ListUserPlaylists`, `GetPlaylist`, `coverArg`, `CreatePlaylist`, `UpdatePlaylist`, `DeletePlaylist`, `ListPlaylistItems`, `AddPlaylistItem`, `RemovePlaylistItem`.
-
-Filter on `collection_type='playlist'` instead of `'manual'`.
-
-**Special handling for `coverArg`:** `abs_playlists` has a `cover_item` foreign key to `media_items`; the canonical `user_personal_collections` has only `poster_url` (text). Per spec §6 open question, the design recommends dropping `cover_item` and regenerating poster URLs from the first item. For this rewrite:
-
-- `coverArg` becomes a noop / removed: the new CreatePlaylist doesn't accept a cover_item field on insert.
-- The wire-shape struct can keep its `CoverItem` field; the rewrite always serializes it as `""` (empty). If the ABS app surfaces a cover, it falls back to the first item's poster — same as the audiobook UI does today.
-
-- [ ] **Step 1: Write a failing test for `ListUserPlaylists`**
-
-```go
-func TestABSPlaylistStoreListUserPlaylists(t *testing.T) {

-```
-
-- [ ] **Step 2: Run the test, fail, then rewrite**
-
-```bash
-go test ./internal/audiobooks/ -run TestABSPlaylistStoreListUserPlaylists -v
-```
-
-Expected: FAIL until rewrite lands.
-
-- [ ] **Step 3: Rewrite `ListUserPlaylists`**
-
-```go
-func (s *ABSPlaylistStore) ListUserPlaylists(ctx context.Context, userID, profileID string) ([]abs.Playlist, error) {
-	const q = `
-		SELECT id, name, description, user_id, is_shared, created_at, updated_at

-		}
-		// CoverItem deliberately left as zero value; see plan + spec §6.
-		out = append(out, p)
-	}
-	return out, rows.Err()
-}
-```
-
-- [ ] **Step 4: Rewrite the remaining methods**
-
-| Method | Canonical operation |
-|---|---|
-| `GetPlaylist(id)` | `SELECT … WHERE id=$1 AND collection_type='playlist'` |
-| `CreatePlaylist(p)` | `INSERT … VALUES (..., 'playlist', ...)` — drop cover_item handling |
-| `UpdatePlaylist(p)` | `UPDATE … SET name=$2, description=$3, is_shared=$4, updated_at=NOW() WHERE id=$1 AND collection_type='playlist'` |
-| `DeletePlaylist(id)` | `DELETE FROM user_personal_collections WHERE id=$1 AND collection_type='playlist'` |
-| `ListPlaylistItems(playlistID)` | `SELECT media_item_id, sub_item_id, position FROM user_personal_collection_items WHERE collection_id=$1 ORDER BY position, added_at` — map `sub_item_id`→`abs.PlaylistItem.EpisodeId` (empty string when no episode) |
-| `AddPlaylistItem(playlistID, libraryItemID, episodeID)` | `INSERT INTO user_personal_collection_items (user_id, collection_id, media_item_id, sub_item_id, position, added_at) SELECT user_id, $1, $2, $3, COALESCE(MAX(i.position)+1, 0), NOW() FROM user_personal_collections c LEFT JOIN user_personal_collection_items i ON i.collection_id = c.id WHERE c.id=$1 GROUP BY user_id` |
-| `RemovePlaylistItem(playlistID, libraryItemID, episodeID)` | `DELETE FROM user_personal_collection_items WHERE collection_id=$1 AND media_item_id=$2 AND sub_item_id=$3` |
-| `coverArg(cover string)` | Delete entirely — no longer used. |
-
-- [ ] **Step 5: Run all playlist tests**
-
-```bash
-go test ./internal/audiobooks/ -run TestABSPlaylistStore -v
-```
-
-Expected: PASS.
-
-- [ ] **Step 6: Commit**
-
-```bash

-## Task 4: Rewrite `ABSSmartCollectionStore`
-
-**Files:**
-- Modify: `internal/audiobooks/abs_smart_collection_store.go`
-- Test: `internal/audiobooks/abs_smart_collection_store_test.go` (create if missing)
-
-Filter on `collection_type='smart'`. The rule DSL stored in `query_definition` (jsonb) — same column the silo-native query_definition uses. Note: the source column on `abs_smart_collections` was named `query_def` (not `query_definition`); the canonical column is `query_definition`. **Read+write target the canonical name.**
-
-`color` and `is_pinned` from `abs_smart_collections` have no canonical equivalent (spec §6 defers them). The rewrite emits empty/false for those fields in the JSON output. If the ABS app silently relies on either, ship a follow-up to add the columns.
-
-- [ ] **Step 1: Write a failing test**
-
-```go
-func TestABSSmartCollectionStoreListUserSmart(t *testing.T) {
-	if testing.Short() { t.Skip("requires test DB") }
-	ctx := context.Background()
-	pool := newTestPool(t)

-	if len(got) != 1 || got[0].Id != "test-sc-1" {
-		t.Errorf("unexpected: %+v", got)
-	}
-}
-```
-
-- [ ] **Step 2: Rewrite the 6 methods**
-
-| Method | Canonical operation |
-|---|---|
-| `ListUserSmartCollections` | `SELECT id, name, description, query_definition, user_id, is_shared FROM user_personal_collections WHERE collection_type='smart' AND user_id=$1::int AND (profile_id=$2 OR ...) ORDER BY created_at DESC` |
-| `GetSmartCollection(id)` | same with `WHERE id=$1 AND collection_type='smart'` |
-| `CreateSmartCollection(c)` | `INSERT … 'smart' … query_definition=$N::jsonb` |
-| `UpdateSmartCollection(c)` | `UPDATE … SET name=$2, description=$3, query_definition=$4, is_shared=$5, updated_at=NOW() WHERE id=$1 AND collection_type='smart'` |
-| `DeleteSmartCollection(id)` | `DELETE FROM user_personal_collections WHERE id=$1 AND collection_type='smart'` |
-| Materializer (if present) | Calls `internal/smartcoll.Evaluate(...)` against `media_items` filtered by `query_definition.library_ids` |
-
-For `color` and `is_pinned`: read from `abs.SmartCollection` zero-value on read paths; ignore on write paths. If the wire shape unconditionally includes them, leave the zero values in place — clients receive `"color":"", "is_pinned":false`.
-
-- [ ] **Step 3: Tests + commit**
-
-Same shape as Tasks 2 and 3. Commit message:
-
-```
-refactor(audiobooks): ABS smart collection store queries canonical tables
-
-Rewrites ABSSmartCollectionStore methods to read/write user_personal_collections
-(collection_type='smart'). Rule DSL goes into query_definition (formerly
-the abs_smart_collections.query_def column).
-
-color and is_pinned have no canonical analog; emitted as zero values.
-See spec §6 for the deferred decision on those columns.

-## Task 5: Wire-shape regression test (snapshot diff)
-
-**Files:**
-- Add or extend: an integration test that drives the ABS handlers and asserts the JSON output for each endpoint hasn't changed.
-
-If a snapshot/golden-file test framework already exists in the repo, use it (`grep -rln 'goldenfile\|snapshot' --include="*_test.go" internal/audiobooks/`). Otherwise this task is **manual verification** captured in the MR description:
-
-- [ ] **Step 1: Seed identical fixtures pre- and post-rewrite**
-
-Before the rewrite commits, seed one of each:
-- An `abs_user_collections` row (pre-migration) with name "FixtureColl", 1 item.
-- An `abs_playlists` row (pre-migration) with name "FixturePL", 1 item with sub_item.
-- An `abs_smart_collections` row (pre-migration) with name "FixtureSmart", rules `{"any":[…]}`.
-
-Capture the JSON response from each list endpoint. Save to `/tmp/wire_before_*.json`.
-
-- [ ] **Step 2: Run migration 156, then seed equivalent rows in canonical tables**
-
-Insert one of each `user_personal_collections` row with the same Id, Name, etc.
-
-Capture the JSON response. Save to `/tmp/wire_after_*.json`.
-
-- [ ] **Step 3: Diff**
-
-```bash
-for kind in collections playlists smart_collections; do
-    diff /tmp/wire_before_${kind}.json /tmp/wire_after_${kind}.json
-done
-```
-
-Expected: empty diff for each. If anything differs, note the field and either patch the rewrite to match or flag it as a wire-shape regression in the PR description so the ABS team is aware.
-
-- [ ] **Step 4: Commit the test (if framework supports it) or paste the diff into the PR description**
-
-```bash
-git add internal/audiobooks/abs_wireshape_test.go  # if applicable
-git commit -m "test(audiobooks): wire-shape snapshot for ABS adapters
-
-Locks in JSON parity for /api/libraries/{id}/collections|playlists|
-smart-collections after the canonical-table cutover."
-```
-
----
-
-## Verification (after merge)
-
-1. Silo binary starts cleanly against a migration-156 DB.
-2. ABS endpoints respond:
-   - `GET /api/libraries/9/collections` — returns the 0 manual collections, no errors.
-   - `GET /api/libraries/9/playlists` — returns the 1 promoted playlist with `Id` preserved.
-   - `GET /api/libraries/9/smart-collections` — returns 0 smart collections, no errors.
-3. ABS Android app (or whatever client is in use) opens the library, sees the same content it saw pre-migration.
-4. Creating a new collection from the ABS app inserts into `user_personal_collections`, not anywhere else:
-
-   ```sql
-   SELECT collection_type, COUNT(*) FROM user_personal_collections GROUP BY 1;
-   ```
-
-   Expected: counts increase for the relevant `collection_type` as the user creates content.
-

-## Self-Review
-
-**Spec coverage:**
-- Collection store rewrite ✓ (Task 2)
-- Playlist store rewrite ✓ (Task 3)
-- Smart collection store rewrite ✓ (Task 4)
-- Wire-shape preservation ✓ (Tasks 1, 5)
-- Drop cover_item ✓ (Task 3, per spec §6)
-- color / is_pinned deferred ✓ (Task 4, per spec §6)
-
-**Placeholder scan:** Task 2 Step 5 lists 7 remaining methods as a table rather than spelling out the full Go body of each. The table gives the exact SQL semantics, the column mappings, and a pointer at the existing file's error-wrap style — sufficient for a competent implementer to write the bodies. The full code for each method would balloon this plan from ~700 to ~2000 lines; the table form is the right granularity. Same applies to Task 3 Step 4 and Task 4 Step 2. Each table entry could equally be a TDD task on its own; the implementer is free to expand any row into a write-test-fail-implement-pass-commit cycle.
-
-**Type consistency:** `abs.Collection`, `abs.Playlist`, `abs.SmartCollection`, `abs.CollectionItem`, `abs.PlaylistItem` referenced consistently. `collection_type` enum values `'manual'`, `'playlist'`, `'smart'` consistent. `sub_item_id` column name consistent.
-
-**Risk:** Largest sub-project of the four. Three files rewritten end-to-end. The biggest risk is wire-shape regressions where a struct field's serialized name differs subtly between adapters — Task 5 mitigates with the diff approach, but it's manual unless a snapshot harness exists. Sub-project 1 must land first; sub-project 2 must land first if Task 4 imports the new `internal/smartcoll` path.

-# Collections Unification — Sub-project 4: Section Recipes for Audiobooks
-
-> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
-
-**Goal:** Make `page_sections` media-type-parameterized so existing recipes can include audiobooks, and add two new audiobook-flavored recipes (`continue_listening`, `by_audiobook_series`).
-
-**Architecture:** Each recipe declaration in `internal/sections/recipes/` exposes a `SupportedMediaTypes` field. `PageSection` rows carry a `media_types text[]` column (added by migration 156 — sub-project 1). The fetchers add `WHERE mi.type = ANY($media_types)` to their queries. Existing recipes default to `['movie','series']` so current behavior is preserved.
-
-**Tech Stack:** Go, PostgreSQL, existing `internal/sections/` + `internal/sections/recipes/` packages.
-
-**Commands assume the repository root is the cwd.**
-
-**Source spec:** `docs/superpowers/specs/2026-05-27-unified-audiobook-collections-design.md` §4.4.
-
-**Predecessor sub-project:** Sub-project 1 (migration 156) must land first — `page_sections.media_types` is required.
-
----
-
-## File map
-
-**Modify:**
-- `internal/sections/types.go` — add `media_types []string` to the `PageSection` Go struct
-- `internal/sections/registry.go` (or wherever recipes are registered — verify via grep) — surface `SupportedMediaTypes()` on the Recipe interface
-- `internal/sections/recipes/*.go` — every recipe file declares its supported types
-- `internal/sections/recipes/registry.go` — recipe registry exposes the supported-types info to the admin API
-- Section fetchers (likely `internal/sections/fetcher.go` or similar) — wire `media_types` into the SQL `WHERE` clause
-
-**Create:**
-- `internal/sections/recipes/continue_listening.go` + test
-- `internal/sections/recipes/by_audiobook_series.go` + test
-
-**Add to admin API:**
-- `internal/api/handlers/recipes.go` — the `GET /api/sections/recipes` endpoint surfaces the per-recipe supported-media-types in its response
-
----
-
-## Task 1: Audit current recipe shape
-
-This task is read-only — produces a working note for the rest of the plan.
-
-- [ ] **Step 1: Map the current recipe interface**
-
-```bash
-grep -nE "type Recipe interface|type RecipeDefinition|func.*Type\(\) string|func.*Definition\(\)|SupportedMediaTypes" internal/sections/recipes/*.go internal/sections/types.go internal/sections/registry.go 2>/dev/null
-```
-
-Read the `Recipe` interface and any current registration code. Note:
-- The exact method signatures recipes already implement.
-- How a recipe is registered (`init()` calls? explicit `Register`? slice literal?).
-- Whether `RecipeDefinition` carries metadata returned to the admin UI; that's where `SupportedMediaTypes` will surface.
-
-- [ ] **Step 2: Map the fetcher's current SQL**
-
-```bash
-grep -nE "FetchOne|FetchSection|SELECT.*FROM media_items|type Fetcher" internal/sections/*.go 2>/dev/null | head -20
-```
-
-Find the function that turns a `ResolvedSection` into a list of `media_items`. Note its query shape — where the `WHERE` clause lives, what parameters it already takes.
-
-- [ ] **Step 3: Note the section persistence shape**
-
-```bash
-grep -nE "INSERT INTO page_sections|UPDATE page_sections|SELECT.*FROM page_sections" internal/sections/*.go internal/api/handlers/sections*.go 2>/dev/null | head -10
-```
-
-Find where `page_sections` rows are read and written. The `media_types` column needs to be read/written there too.
-
-No commit for this task — it produces a mental map you'll reference in Tasks 2–5.

-**Files:**
-- Modify: `internal/sections/types.go` (`PageSection` struct)
-- Modify: wherever `page_sections` rows are scanned and written (from Task 1 Step 3)
-
-- [ ] **Step 1: Write failing test for `media_types` round-trip**
-
-The test goes in whichever package owns the `PageSection` repository — likely `internal/sections/` itself. If a repository test file exists, append; otherwise create one:
-
-```go
-func TestPageSectionMediaTypesRoundTrip(t *testing.T) {
-	if testing.Short() { t.Skip("requires test DB") }
-	ctx := context.Background()
-	pool := newTestPool(t) // adapt to project's test pool harness
-
-	repo := NewSectionRepository(pool)
-
-	sec := &PageSection{
-		Name:        "Audiobook test",
-		RecipeType:  "library_staples",
-		MediaTypes:  []string{"audiobook"},
-		// ...fill in other required fields from the struct definition
-	}
-	if err := repo.Create(ctx, sec); err != nil {
-		t.Fatalf("Create: %v", err)
-	}
-	got, err := repo.GetByID(ctx, sec.ID)
-	if err != nil {
-		t.Fatalf("GetByID: %v", err)
-	}
-	if !reflect.DeepEqual(got.MediaTypes, []string{"audiobook"}) {
-		t.Errorf("MediaTypes = %v, want [audiobook]", got.MediaTypes)
-	}
-}
-```
-
-Adapt the constructor name, struct fields, and DB harness to actual project shape (found in Task 1).
-
-- [ ] **Step 2: Run the test to confirm failure**
-
-Run: `go test ./internal/sections/ -run TestPageSectionMediaTypesRoundTrip -v`
-Expected: FAIL — the `MediaTypes` field doesn't exist yet.
-
-- [ ] **Step 3: Add the field to `PageSection`**
-
-In `internal/sections/types.go`, find the `PageSection` struct (or whatever it's called per Task 1's audit) and add:
-
-```go
-type PageSection struct {
-    // ...existing fields
-    MediaTypes []string `json:"media_types" db:"media_types"`
-}
-```
-
-If the project's struct tagging convention differs, follow that convention. The DB column is `text[]`; the Go type is `[]string`. pgx's default decoder handles this directly.
-
-- [ ] **Step 4: Update the repository's read/write SQL**
-
-For each `INSERT`/`UPDATE` against `page_sections`, add `media_types` to the column list and bind parameter list. For each `SELECT`, add it to the projection and scan into the new field.
-
-Example pattern (adapt to actual code):
-
-```go
-const insertSQL = `
-    INSERT INTO page_sections (id, name, recipe_type, ..., media_types)
-    VALUES ($1, $2, $3, ..., $N::text[])
-`
-// ...
-_, err := pool.Exec(ctx, insertSQL, sec.ID, sec.Name, sec.RecipeType, ..., sec.MediaTypes)
-```
-
-For SELECTs, add `media_types` to the projection and `&sec.MediaTypes` to the scan list.
-
-- [ ] **Step 5: Run the test, verify pass**
-
-Run: `go test ./internal/sections/ -run TestPageSectionMediaTypesRoundTrip -v`
-Expected: PASS.
-
-- [ ] **Step 6: Build + broader test**
-
-```bash
-go build ./...
-go test ./internal/sections/ ./internal/api/handlers/ -short -timeout 90s
-```
-
-Expected: clean.
-
-- [ ] **Step 7: Commit**
-
-```bash
-git add internal/sections/types.go internal/sections/*.go internal/api/handlers/sections*.go
-git commit -m "feat(sections): expose page_sections.media_types in Go
-
-Adds MediaTypes []string to PageSection + repo read/write paths.
-Migration 156 (sub-project 1) added the underlying column with
-DEFAULT ARRAY['movie','series']; existing rows retain that default,
-preserving today's behavior."
-```
-
-Only stage the files you actually modified. Verify with `git diff --cached --stat` before commit.

-## Task 3: Recipe interface — `SupportedMediaTypes`
-
-**Files:**
-- Modify: `internal/sections/recipes/registry.go` (interface declaration)
-- Modify: every `*.go` recipe file in `internal/sections/recipes/` (each gains a one-line method)
-
-- [ ] **Step 1: Find the Recipe interface**
-
-```bash
-grep -n "type Recipe " internal/sections/recipes/*.go internal/sections/*.go
-```
-
-Note the file + line of the interface declaration.
-
-- [ ] **Step 2: Add a `SupportedMediaTypes()` method to the interface**
-
-In whichever file declares the interface:
-
-```go
-type Recipe interface {
-    // ...existing methods
-    SupportedMediaTypes() []string
-}
-```
-
-- [ ] **Step 3: Implement on every existing recipe**
-
-For each `*Recipe` struct in `internal/sections/recipes/`, add the method. Existing recipes default to movies+series to preserve behavior:
-
-```go
-func (libStaple) SupportedMediaTypes() []string         { return []string{"movie", "series"} }
-func (moodRecipe) SupportedMediaTypes() []string        { return []string{"movie", "series"} }
-func (handPickedRecipe) SupportedMediaTypes() []string  { return []string{"movie", "series"} }
-// ...and so on for every recipe in the directory
-```
-
-Use this enumeration as a checklist (from `ls internal/sections/recipes/*.go`, excluding tests):
-
-- admin_curated_list
-- custom
-- discovery
-- editorial
-- hand_picked
-- library_staples
-- mood
-- personalized
-
-Each gets one method. Audiobook-eligible recipes — `library_staples`, `discovery`, `hand_picked`, `mood`, `personalized` — extend to include `"audiobook"` if their underlying query already handles all `media_items.type` values transparently. Conservative call: only `library_staples` extends to all three on this pass. The rest stay movies+series until each one's recipe-specific query is audited. **Bias toward the conservative default.**
-
-Specifically:
-
-```go
-func (libStaple) SupportedMediaTypes() []string { return []string{"movie", "series", "audiobook"} }
-```
-
-- [ ] **Step 4: Build**
-
-```bash
-go build ./...
-```
-
-Expected: clean. If any recipe is missed, the Go compiler will complain that the type doesn't satisfy the interface.
-
-- [ ] **Step 5: Commit**
-
-```bash
-git add internal/sections/recipes/
-git commit -m "feat(recipes): SupportedMediaTypes per recipe
-
-Adds the SupportedMediaTypes() method to the Recipe interface and
-implements it on each existing recipe. Conservative defaults preserve
-today's behavior: only library_staples opens to audiobooks; others
-stay movies+series until their underlying queries are audited."
-```

-## Task 4: Fetcher applies the `media_types` filter
-
-**Files:**
-- Modify: the section fetcher implementation file (found in Task 1 Step 2)
-
-- [ ] **Step 1: Write a failing test**
-
-Append to (or create) the fetcher's test file. Pattern:
-
-```go
-func TestFetcherFiltersByMediaTypes(t *testing.T) {
-	if testing.Short() { t.Skip("requires test DB") }
-	ctx := context.Background()
-	pool := newTestPool(t)
-
-	// Seed: one movie, one audiobook, both eligible for the same recipe.
-	seedTestMediaItem(t, pool, "mov-1", "movie", "Test Movie")
-	seedTestMediaItem(t, pool, "ab-1", "audiobook", "Test Book")
-
-	fetcher := NewFetcher(pool)
-
-	t.Run("media_types movies only", func(t *testing.T) {
-		got, _ := fetcher.FetchOne(ctx, ResolvedSection{
-			SectionType: "library_staples",
-			MediaTypes:  []string{"movie"},
-		}, nil, nil, 1, "", catalog.AccessFilter{})
-		assertContains(t, got.Items, "mov-1")
-		assertExcludes(t, got.Items, "ab-1")
-	})
-
-	t.Run("media_types audiobook only", func(t *testing.T) {
-		got, _ := fetcher.FetchOne(ctx, ResolvedSection{
-			SectionType: "library_staples",
-			MediaTypes:  []string{"audiobook"},
-		}, nil, nil, 1, "", catalog.AccessFilter{})
-		assertContains(t, got.Items, "ab-1")
-		assertExcludes(t, got.Items, "mov-1")
-	})
-
-	t.Run("media_types both", func(t *testing.T) {
-		got, _ := fetcher.FetchOne(ctx, ResolvedSection{
-			SectionType: "library_staples",
-			MediaTypes:  []string{"movie", "audiobook"},
-		}, nil, nil, 1, "", catalog.AccessFilter{})
-		assertContains(t, got.Items, "mov-1", "ab-1")
-	})
-}
-```
-
-Adapt `ResolvedSection`, `FetchOne` signature, `seedTestMediaItem`, `assertContains` / `assertExcludes` to the project's actual shapes. The exact assertions depend on what `SectionWithItems` exposes — likely a `.Items []SectionItem` slice.
-
-- [ ] **Step 2: Run the test, verify fail**
-
-```bash
-go test ./internal/sections/ -run TestFetcherFiltersByMediaTypes -v
-```
-
-Expected: FAIL — `ResolvedSection.MediaTypes` field doesn't exist yet OR the fetcher SQL doesn't filter.
-
-- [ ] **Step 3: Add `MediaTypes` to `ResolvedSection`**
-
-In `internal/sections/types.go` (or wherever `ResolvedSection` lives):
-
-```go
-type ResolvedSection struct {
-    // ...existing fields
-    MediaTypes []string
-}
-```
-
-The resolver code that builds `ResolvedSection` from a `PageSection` row needs one more line to pass `MediaTypes` through. Find it:
-
-```bash
-grep -n "ResolvedSection{" internal/sections/*.go internal/api/handlers/*.go
-```
-
-For each instance that builds one from a `PageSection`, add `MediaTypes: section.MediaTypes,`.
-
-- [ ] **Step 4: Wire the filter into the fetcher SQL**
-
-In the fetcher implementation, find the query that pulls `media_items`. Add to its `WHERE` clause:
-
-```go
-const query = `
-    SELECT ...
-    FROM media_items mi
-    WHERE ...
-      AND mi.type = ANY($N::text[])
-    ...
-`
-// ...
-rows, err := pool.Query(ctx, query, ..., mediaTypes)
-```
-
-If the fetcher dispatches to per-recipe resolvers, the filter goes inside each resolver's query. Most likely there's a shared query-building helper — find it via `grep -n "type = ANY\|recipe.*Resolve" internal/sections/`.
-
-If the fetcher receives a `ResolvedSection` and dispatches to recipe resolvers based on `SectionType`, the resolvers each accept the `MediaTypes` slice as part of their `ResolverContext` (or whatever the recipe-side context type is). Add a field to that context type and thread it through.
-
-**Validation rule**: the fetcher must reject a request where `ResolvedSection.MediaTypes` contains a type not in the recipe's `SupportedMediaTypes()`. Add this guard in the dispatch path:
-
-```go
-recipe, ok := registry.Get(resolved.SectionType)
-if !ok { return result, fmt.Errorf("unknown recipe %q", resolved.SectionType) }
-supported := setOf(recipe.SupportedMediaTypes())
-for _, mt := range resolved.MediaTypes {
-    if _, ok := supported[mt]; !ok {
-        return result, fmt.Errorf("recipe %q does not support media type %q", resolved.SectionType, mt)
-    }
-}
-```
-
-`setOf` is a 3-line helper that returns `map[string]struct{}` from a slice.
-
-- [ ] **Step 5: Run the test, verify pass**
-
-```bash
-go test ./internal/sections/ -run TestFetcherFiltersByMediaTypes -v
-```
-
-Expected: PASS for all three subtests.
-
-- [ ] **Step 6: Commit**
-
-```bash
-git add internal/sections/
-git commit -m "feat(sections): fetcher honors media_types filter
-
-ResolvedSection carries a MediaTypes slice. Fetcher dispatch validates
-the slice against the recipe's SupportedMediaTypes() and forwards it
-into the underlying SQL (WHERE mi.type = ANY(\$N::text[]))."
-```

-## Task 5: New recipe — `continue_listening`
-
-**Files:**
-- Create: `internal/sections/recipes/continue_listening.go`
-- Create: `internal/sections/recipes/continue_listening_test.go`
-
-The audiobook analog of `continue_watching`. Surfaces audiobook items the user has progress on but hasn't finished.
-
-- [ ] **Step 1: Read the existing `continue_watching` recipe (if present)**
-
-```bash
-ls internal/sections/recipes/ | grep -i continue
-grep -rln "continue_watching\|user_watch_progress" internal/sections/recipes/ internal/sections/
-```
-
-Identify the closest analog. Copy its overall structure (registration, params struct, Resolve method shape). The audiobook version differs only in `type = 'audiobook'` filter and possibly which progress columns it inspects (audiobook progress may live in the same `user_watch_progress` table — verify with `\d user_watch_progress` against the DB).
-
-- [ ] **Step 2: Write a failing test**
-
-```go
-package recipes

-**Adapt the field names** (`PosterPath`, `Pool`, `UserID`, `Ctx`, `Params`, etc.) to whatever the existing recipes use. **Adapt the SQL** to the actual `user_watch_progress` column names — verify with `\d user_watch_progress` against the DB.

-## Task 7: Surface `SupportedMediaTypes` in admin API response
-
-**Files:**
-- Modify: `internal/api/handlers/recipes.go` (`GET /api/sections/recipes` handler)
-
-The admin section-builder UI needs to know which recipes support audiobooks so it can offer the media-types multi-select to the operator. The handler's response shape adds one field per recipe.
-
-- [ ] **Step 1: Read the current handler**
-
-```bash
-cat internal/api/handlers/recipes.go
-```
-
-Note the response struct shape — probably `[]RecipeInfo` or similar with `Type`, `Name`, `Description`.
-
-- [ ] **Step 2: Add `SupportedMediaTypes` to the response**
-
-In the response struct definition, add:
-
-```go
-type recipeInfo struct {
-    Type                string   `json:"type"`
-    Name                string   `json:"name"`
-    Description         string   `json:"description"`
-    SupportedMediaTypes []string `json:"supported_media_types"`
-}
-```
-
-In the handler body, set `SupportedMediaTypes: recipe.SupportedMediaTypes()`.
-
-- [ ] **Step 3: Test**
-
-If the project has a handler test for `GET /api/sections/recipes`, extend it. Otherwise the manual verification step covers this:
-
-```bash
-curl -sH "Authorization: Bearer $TOKEN" http://localhost:8090/api/sections/recipes | jq '.[] | select(.type=="continue_listening")'
-# Expected: { "type":"continue_listening", "name":"Continue Listening", ..., "supported_media_types":["audiobook"] }
-```
-
-- [ ] **Step 4: Commit**
-
-```bash
-git add internal/api/handlers/recipes.go
-git commit -m "feat(api): expose supported_media_types in /api/sections/recipes
-
-Admin UI section-builder uses this to gate the media-types
-multi-select per recipe."
-```
-
----
-
-## Verification (after merge)
-
-1. Existing sections continue to work — their `media_types` defaults to `['movie','series']` so query results are unchanged.
-2. Creating a section with `media_types=['audiobook']` and `recipe_type='library_staples'` returns audiobook items.
-3. Two new recipes registered:
-   ```bash
-   curl -sH "Authorization: Bearer $TOKEN" http://localhost:8090/api/sections/recipes | jq '[.[] | .type] | sort'
-   ```
-   Expected: includes `"continue_listening"` and `"by_audiobook_series"` along with the existing types.
-4. A user with active audiobook progress sees the `continue_listening` rail return their in-progress books.
-5. The admin section-builder UI (if updated) lets the operator pick `media_types` for any recipe whose `SupportedMediaTypes` includes that type.
-

-
-## Self-Review
-
-**Spec coverage:**
-- `page_sections.media_types` Go-side serde ✓ (Task 2)
-- `Recipe.SupportedMediaTypes()` on every recipe ✓ (Task 3)
-- Fetcher filter by `media_types` ✓ (Task 4)
-- `continue_listening` recipe ✓ (Task 5)
-- `by_audiobook_series` recipe ✓ (Task 6)
-- Admin API exposes per-recipe types ✓ (Task 7)
-
-**Placeholder scan:** Test bodies in Tasks 5 and 6 are partly stubbed with `t.Skip(...)` to be filled in by reading the existing `continue_watching` test pattern. That's a deliberate "read-existing-then-write" instruction, not a TBD. The other stubs (test pool harness lookups, schema verification queries) are explicit grep commands the implementer runs at start of the task. No abstract "implement appropriately."
-
-**Type consistency:** `SupportedMediaTypes`, `MediaTypes`, `ResolverContext`, `ResolvedItems`, recipe `Type()` string values all consistent across tasks.
-
-**Risk:** Lowest-risk of the 4 sub-projects. The fetcher change has an explicit failing-test guard (Task 4 Step 1) so regression is unlikely. The two new recipes are additive; even if one's SQL is mis-specified, existing recipes are unaffected. The main risk is the audit decision in Task 3 Step 3 — being too aggressive (extending too many recipes to audiobooks) could surface bad audiobook rails on existing sections; being too conservative wastes the parameterization. Conservative is the safer default.

+# Resilient Library Deletion Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Rewrite `delete_library` so it deletes a library in small, autocommitted, deadlock-retrying batches instead of one multi-minute transaction that deadlocks and rolls back on large libraries.
+
+**Architecture:** `FolderRepository.DeleteWithStats` becomes a phased, batched operation (orphan items → folder media_files → remaining shared junctions → folder row). Each batch is one autocommit statement wrapped in a `retryOnDeadlock` helper, so locks are held briefly and the job is resumable. Two small helpers (`retryOnDeadlock`, `deleteInBatches`) are unit-tested in pure Go; the full path is verified against the live dev database.

+**Tech Stack:** Go, pgx v5 (`pgxpool`, `pgconn`), PostgreSQL. Spec: `docs/superpowers/specs/2026-05-28-library-delete-resilience-design.md`.
+
+All commands assume the repository root is the cwd.
+

+
+## File Structure
+
+- **Modify** `internal/catalog/folder_repo.go`
+  - Add constants `orphanDeleteBatch`, `folderChildDeleteBatch`.
+  - Add package vars `deadlockMaxAttempts`, `deadlockBaseBackoff` and func `retryOnDeadlock`.
+  - Add func `deleteInBatches`.
+  - Add interface `rowQuerier`; change `collectImageDirs` and `filterUnreferencedImageDirs` to take `rowQuerier` instead of `pgx.Tx`; extract `collectRawImageDirs`.
+  - Rewrite `DeleteWithStats`; add helpers `collectOrphanBatch`, `dirSetToSlice`.
+  - Leave `collectOrphanIDs` and `Delete` unchanged.
+- **Create** `internal/catalog/folder_delete_test.go` — pure-Go unit tests for `retryOnDeadlock` and `deleteInBatches`.
+- **Do not modify** `internal/catalog/library_repo.go` — its `collectImageDirs`/`collectOrphanIDs` calls keep compiling because `pgx.Tx` satisfies `rowQuerier`. (Verified by build.)
+- **Unchanged behavior** in `internal/adminjob/library_delete.go` (executor), `internal/adminjob/runner.go` (heartbeat).

+## Task 3: Generalize image-dir helpers to a querier interface
+
+This lets the image-dir helpers run on either a `*pgxpool.Pool` (new batched path) or a `pgx.Tx` (existing `library_repo.go` path), and splits raw collection from filtering so the batched path can collect cheaply per batch and filter once.
+
+**Files:**
+- Modify: `internal/catalog/folder_repo.go:547-635` (the `collectImageDirs` / `filterUnreferencedImageDirs` block)
+
+- [ ] **Step 1: Add the `rowQuerier` interface**
+
+In `internal/catalog/folder_repo.go`, add (near the other type declarations, e.g. just above `collectOrphanIDs`):
+
+```go
+// rowQuerier is satisfied by both *pgxpool.Pool and pgx.Tx, letting read
+// helpers run inside or outside an explicit transaction.
+type rowQuerier interface {
+	Query(ctx context.Context, sql string, args ...any) (pgx.Rows, error)
+}
+```
+
+- [ ] **Step 2: Split `collectImageDirs` into raw collection + filtering**
+
+Replace the existing `collectImageDirs` function (currently `internal/catalog/folder_repo.go:549-584`) with these two functions:
+
+```go
+// collectImageDirs returns S3 directory prefixes for images belonging to the
+// given content IDs that are not still referenced by other surviving content.
+func collectImageDirs(ctx context.Context, q rowQuerier, contentIDs []string) ([]string, error) {
+	dirs, err := collectRawImageDirs(ctx, q, contentIDs)
+	if err != nil {
+		return nil, err
+	}
+	return filterUnreferencedImageDirs(ctx, q, dirs, contentIDs)
+}
+
+// collectRawImageDirs returns the deduped S3 directory prefixes referenced by
+// the given content IDs (items, their seasons, and their episodes), without
+// filtering out dirs still used by other content.
+func collectRawImageDirs(ctx context.Context, q rowQuerier, contentIDs []string) ([]string, error) {
+	imgRows, err := q.Query(ctx, `
+		SELECT poster_path, backdrop_path, logo_path FROM media_items WHERE content_id = ANY($1)
+		UNION ALL
+		SELECT poster_path, '', '' FROM seasons WHERE series_id = ANY($1)
+		UNION ALL
+		SELECT still_path, '', '' FROM episodes WHERE series_id = ANY($1)
+	`, contentIDs)
+	if err != nil {
+		return nil, fmt.Errorf("collecting image paths: %w", err)
+	}
+	defer imgRows.Close()
+	dirSet := make(map[string]struct{})
+	for imgRows.Next() {
+		var p1, p2, p3 string
+		if err := imgRows.Scan(&p1, &p2, &p3); err != nil {
+			return nil, fmt.Errorf("scanning image path: %w", err)
+		}
+		for _, p := range []string{p1, p2, p3} {
+			if p != "" && !strings.Contains(p, "://") {
+				if dir := pathDir(p); dir != "" {
+					dirSet[dir] = struct{}{}
+				}
+			}
+		}
+	}
+	if err := imgRows.Err(); err != nil {
+		return nil, fmt.Errorf("iterating image paths: %w", err)
+	}
+	dirs := make([]string, 0, len(dirSet))
+	for dir := range dirSet {
+		dirs = append(dirs, dir)
+	}
+	return dirs, nil
+}
+```
+
+- [ ] **Step 3: Change `filterUnreferencedImageDirs` to take `rowQuerier`**
+
+In `internal/catalog/folder_repo.go`, change the signature (currently `internal/catalog/folder_repo.go:586`) from:
+
+```go
+func filterUnreferencedImageDirs(ctx context.Context, tx pgx.Tx, dirs, deletingContentIDs []string) ([]string, error) {
+```
+
+to:
+
+```go
+func filterUnreferencedImageDirs(ctx context.Context, q rowQuerier, dirs, deletingContentIDs []string) ([]string, error) {
+```
+
+and change the single `tx.Query(ctx, ...)` call inside it to `q.Query(ctx, ...)`. Leave the SQL and the rest of the body unchanged.
+
+- [ ] **Step 4: Verify the build (proves `library_repo.go` still compiles with `pgx.Tx`)**
+
+Run: `go build ./... && go vet ./internal/catalog/`
+Expected: no errors. (`library_repo.go` passes a `pgx.Tx` to `collectImageDirs`, which now accepts `rowQuerier`; `pgx.Tx` satisfies it.)
+
+- [ ] **Step 5: Run the catalog tests**
+
+Run: `go test ./internal/catalog/...`
+Expected: PASS (existing tests plus Tasks 1–2 helpers).
+
+- [ ] **Step 6: Format and commit**
+
+```bash
+gofmt -w internal/catalog/folder_repo.go
+git add internal/catalog/folder_repo.go
+git commit -m "refactor(catalog): make image-dir helpers querier-agnostic"
+```

+
+## Task 4: Rewrite `DeleteWithStats` as a batched, phased operation
+
+**Files:**
+- Modify: `internal/catalog/folder_repo.go:415-511` (the `DeleteWithStats` body) and add two helpers + two constants.
+
+- [ ] **Step 1: Add the batch-size constants**
+
+In `internal/catalog/folder_repo.go`, add near the retry vars from Task 1:
+
+```go
+const (
+	// orphanDeleteBatch is small because each media_items row cascades across
+	// ~15 child tables.
+	orphanDeleteBatch = 1000
+	// folderChildDeleteBatch covers the lighter folder-scoped media_files and
+	// junction deletes.
+	folderChildDeleteBatch = 5000
+)
+```
+
+- [ ] **Step 2: Replace the `DeleteWithStats` body**
+
+Replace the entire existing `DeleteWithStats` function (`internal/catalog/folder_repo.go:415-511`) with:
+
+```go
+func (r *FolderRepository) DeleteWithStats(
+	ctx context.Context,
+	id int,
+	progress func(current, total int, message string),
+) (*DeleteFolderStats, error) {

+	// Phase 0: preflight reads (no long-lived transaction).
+	if err := r.pool.QueryRow(ctx, `SELECT name FROM media_folders WHERE id = $1`, id).Scan(&stats.LibraryName); err != nil {

+Note: this removes the old single-transaction body (`tx, err := r.pool.Begin(...)`, the inline orphan-collection loop, the `collectImageDirs` call, the CASCADE folder drop, and `tx.Commit`). `collectOrphanIDs` and `Delete` are untouched. `collectImageDirs` remains (still used by `library_repo.go`).
+
+- [ ] **Step 3: Verify the build and vet**
+
+Run: `go build ./... && go vet ./internal/catalog/`
+Expected: no errors. If `go vet` flags an unused function, confirm it is genuinely unused before removing — `collectImageDirs`, `collectOrphanIDs`, and `pathDir` must all remain (still referenced).
+
+- [ ] **Step 4: Run the full catalog + adminjob test suites**
+
+Run: `go test ./internal/catalog/... ./internal/adminjob/...`
+Expected: PASS. (No DB-backed test exercises `DeleteWithStats`; the helper unit tests and existing tests must stay green.)
+
+- [ ] **Step 5: Lint**
+
+Run: `golangci-lint run ./internal/catalog/...`
+Expected: no findings. (If `golangci-lint` is unavailable, run `gofmt -l internal/catalog/` and ensure it prints nothing.)
+
+- [ ] **Step 6: Format and commit**
+
+```bash
+gofmt -w internal/catalog/folder_repo.go
+git add internal/catalog/folder_repo.go
+git commit -m "fix(catalog): delete libraries in deadlock-retrying batches
+
+Replaces the single multi-minute delete transaction with phased, batched
+autocommit deletes (orphan items, media files, memberships, folder row),
+each retried on deadlock. Holds only short locks, survives concurrent
+writers, and is resumable on failure."
+```
+
+---
+
+## Task 5: Verify on the dev server
+
+This is the integration test (no catalog DB harness exists). Follow the deployment-debugging runbook. The Audiobooks library (folder id 8) is currently stuck with ~249K items / ~339K files.
+
+- [ ] **Step 1: Deploy the branch to dev**
+
+Run: `make dev-deploy`
+Expected: builds `silo:dev-local`, recreates the `silo` service. Then confirm health:
+`ssh "$DEV_HOST" 'curl -s http://localhost:8090/api/v1/ready'`
+
+- [ ] **Step 2: Capture the starting counts**
+
+Run (psql via the dev compose `postgres` service, user/db `continuum`):
+
+```sql
+SELECT
+  (SELECT COUNT(*) FROM media_files WHERE media_folder_id = 8) AS files,
+  (SELECT COUNT(*) FROM media_item_libraries WHERE media_folder_id = 8) AS links,
+  (SELECT EXISTS (SELECT 1 FROM media_folders WHERE id = 8)) AS folder_exists;
+```
+
+Expected: non-zero files/links, `folder_exists = t`.
+
+- [ ] **Step 3: Trigger the deletion**
+
+Re-trigger the library deletion through the normal path (admin UI "delete library" for Audiobooks, or the admin delete endpoint). Confirm a new job is queued:
+
+```sql
+SELECT id, job_type, status, requested_at
+FROM admin_jobs WHERE job_type = 'delete_library'
+ORDER BY requested_at DESC LIMIT 3;
+```
+
+- [ ] **Step 4: Monitor to completion**
+
+Watch the job and the draining counts (re-run periodically):
+
+```sql
+SELECT id, status, progress_current, progress_total, error_message, heartbeat_at
+FROM admin_jobs WHERE job_type = 'delete_library'
+ORDER BY requested_at DESC LIMIT 1;
+```
+
+```sql
+SELECT COUNT(*) FROM media_item_libraries WHERE media_folder_id = 8;
+```
+
+Also confirm deadlock retries (if any) are recovered rather than fatal:
+`ssh "$DEV_HOST" "$DEV_COMPOSE_CMD logs postgres 2>&1 | grep -i deadlock | tail -20"`
+Expected: the job reaches `status = completed`; counts trend to 0; any deadlocks are transient (the job does not fail).
+
+- [ ] **Step 5: Confirm full removal**
+
+```sql
+SELECT
+  (SELECT COUNT(*) FROM media_files WHERE media_folder_id = 8) AS files,
+  (SELECT COUNT(*) FROM media_item_libraries WHERE media_folder_id = 8) AS links,
+  (SELECT EXISTS (SELECT 1 FROM media_folders WHERE id = 8)) AS folder_exists;
+```
+
+Expected: `files = 0`, `links = 0`, `folder_exists = f`.
+
+- [ ] **Step 6: Report**
+
+Summarize: starting counts, time to completion, number of batches/retries observed, and final state. No commit (verification only).

+## Self-Review
+
+**Spec coverage:**
+- Phased batched deletion (Phases 0–4) → Task 4. ✔
+- `retryOnDeadlock` (40P01/40001, 5 attempts, backoff, ctx-aware) → Task 1. ✔
+- Batch sizes `orphanDeleteBatch=1000`, `folderChildDeleteBatch=5000` → Task 4 Step 1. ✔
+- Autocommit per batch / no long transaction → Task 4 Step 2 (uses `r.pool.Exec`, no `Begin`). ✔
+- Stats + progress + heartbeat reliance → Task 4 Step 2; runner heartbeat unchanged. ✔
+- Resumability (folder row last, tolerate 0 rows) → Task 4 Phase 4. ✔
+- Unit tests for retry + batch loop → Tasks 1–2. ✔
+- `collectImageDirs` shared with `library_repo.go` preserved → Task 3 (interface widening), Task 4 Step 3 build check. ✔
+- Dev integration verification → Task 5. ✔
+- Out of scope (writer coordination, runner/executor changes, schema changes) → not present in any task. ✔
+
+**Placeholder scan:** No TBD/TODO; every code step has complete code; every command has expected output. ✔
+
+**Type consistency:** `retryOnDeadlock(ctx, func() error) error`, `deleteInBatches(ctx, int, func(ctx) (int64,error)) (int64,error)`, `rowQuerier{ Query(ctx,string,...any)(pgx.Rows,error) }`, `collectRawImageDirs`/`collectImageDirs`/`filterUnreferencedImageDirs(ctx, rowQuerier, ...)`, `collectOrphanBatch(ctx,int,int)([]string,error)`, `dirSetToSlice(map[string]struct{})[]string`, consts `orphanDeleteBatch`/`folderChildDeleteBatch`, vars `deadlockMaxAttempts`/`deadlockBaseBackoff` — names used consistently across tasks. ✔

+# Autoscan Host Backend Implementation Plan (Part 1 of 2)
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Build the silo-server backend for the standalone Autoscan category: poll `scan_source.v1` plugins on a timer, resolve their Silo-native paths to library folders, and enqueue rescans — with connections decoupled from Requests.
+
+**Architecture:** Mirror the existing `scheduled_task.v1` host dispatch (`pluginhost.Client` capability wrapper + `plugins.Service` resolver + a `taskmanager` task). Generalize the closed PR #43 autoscan engine (resolve → suppress → enqueue) so its input is "Silo-native paths from a scan-source plugin" instead of "arr history." Replace the old `request_integrations`-coupled schema with `autoscan_connections` + `autoscan_sources`.
+
+**Tech Stack:** Go, pgx/v5, the `internal/plugins`/`internal/pluginhost` runtime, `internal/scantrigger`/`internal/scanqueue`, `internal/taskmanager`, numbered SQL migrations, `github.com/Silo-Server/silo-plugin-sdk` (the new `scan_source.v1` capability).
+
+Commands assume the silo-server repository root is the cwd. This is **Part 1 (backend)**; the Autoscan admin UI is Part 2.
+
+---
+
+## Prerequisites
+
+1. **SDK dependency.** This plan needs the SDK's `scan_source.v1` symbols (`runtime.Client.ScanSource()`, `pluginv1.ScanSourceClient`, `pluginv1.PollChangesRequest/Response`, `capability.ScanSource`). They are in `silo-plugin-sdk` PR #2 but **not yet released**. Until `v0.5.0` is tagged, add a local replace directive so the host builds against the working checkout:
+
+   ```bash
+   # from the repository root (cwd)
+   go mod edit -replace github.com/Silo-Server/silo-plugin-sdk=../silo-plugin-sdk
+   go mod tidy
+   ```
+
+   This points the replace at the `silo-plugin-sdk` checkout (a sibling of this repo).
+
+   The final task removes the replace and bumps to the tagged version.
+
+2. **Closed PR #43 is on `main`.** The in-process arr autoscan (`internal/autoscan/*`, `internal/api/handlers/autoscan.go`, `internal/taskmanager/tasks/autoscan_poll.go`, router routes, migration `171_autoscan`, the `AdminRequests.tsx` tab) is the salvage source. This plan **generalizes the engine and replaces the schema/wiring**; it does not preserve the arr-specific history client (that moves to the arr plugin in a separate plan).
+
+3. **Tests that touch `internal/api/handlers` or `internal/api` link libvips via CGO.** Run the suite in the libvips-equipped container (see project memory `silo-test-libvips-gotcha`), not the bare host, or those packages report `[build failed]` and skip silently.
+
+---
+
+## Pattern references (read before starting)
+
+- Host capability client wrapper: `internal/pluginhost/client.go` — `ScheduledTaskClient` type (l.42), `Client.ScheduledTask` accessor (l.111), `requireCapability` (l.157), `Run` (l.226).
+- Host resolver: `internal/plugins/service.go:413` `ScheduledTaskClient(ctx, installationID, capabilityID)` → `ensureClient` → `client.ScheduledTask(capabilityID)`.
+- Timer task over plugin capabilities: `internal/plugins/task_registry.go` (iterate enabled installations, filter capability type, build a `taskmanager.Task`).
+- Salvageable engine (generalize, don't rewrite): `internal/autoscan/service.go` (resolve/suppress/enqueue loop), `dedupe.go` (`uniqueParentDirs`), `suppress.go` (`Suppressor`). Discard `history.go`, `rewrite.go`, `suggest*.go` (arr-specific → arr plugin).
+- Migration mechanics: paired `migrations/NNN_*.up.sql`/`.down.sql`, embedded via `migrations/embed.go`, auto-applied on boot.
+- Credential decryption for the reuse-from-Requests case: `internal/requests/repository.go` (`integrationColumns` has `base_url, api_key_ref`); Fernet resolution via `catalog.ServerSettingsRepo.Get` (the same path PR #43's `SecretResolver` used).

+## Task 1: Host `pluginhost` client wrapper for `scan_source.v1`
+
+**Files:**
+- Modify: `internal/pluginhost/client.go`
+- Modify: `internal/pluginhost/client_test.go`
+
+- [ ] **Step 1: Write the failing test**
+
+In `internal/pluginhost/client_test.go`, add a test mirroring the existing `scheduled_task` capability-gate test (find it first; it constructs a `Client` with a manifest declaring a capability and asserts the accessor errors when the capability is absent and succeeds when present):
+
+```go
+func TestClientScanSourceRequiresCapability(t *testing.T) {
+	// Client whose manifest does NOT declare scan_source.v1
+	c := newTestClientWithCapabilities(t, "metadata_provider.v1")
+	if _, err := c.ScanSource("missing"); err == nil {
+		t.Fatal("ScanSource: expected error when capability absent")
+	}
+	// Client WHOSE manifest declares scan_source.v1 with id "arr"
+	c2 := newTestClientWithCapabilities(t, "scan_source.v1:arr")
+	if _, err := c2.ScanSource("arr"); err != nil {
+		t.Fatalf("ScanSource: unexpected error when capability present: %v", err)
+	}
+}
+```
+
+Use whatever helper the sibling `scheduled_task` test uses to construct a `Client` with declared capabilities; mirror it exactly (do not invent a helper that does not exist — read `client_test.go` and copy the construction).
+
+- [ ] **Step 2: Run test to verify it fails**
+
+Run: `go test ./internal/pluginhost/ -run TestClientScanSourceRequiresCapability`
+Expected: FAIL — `c.ScanSource undefined`.
+
+- [ ] **Step 3: Add the wrapper type and accessor**
+
+In `internal/pluginhost/client.go`, after the `ScheduledTaskClient` type (l.42), add:
+
+```go
+type ScanSourceClient struct {
+	client  pluginv1.ScanSourceClient
+	timeout time.Duration
+}
+```
+
+After the `Client.ScheduledTask` accessor (l.117), add:
+
+```go
+func (c *Client) ScanSource(capabilityID string) (*ScanSourceClient, error) {
+	if err := c.requireCapability("scan_source.v1", capabilityID); err != nil {
+		return nil, err
+	}
+	return &ScanSourceClient{
+		client:  c.rpc.ScanSource(),
+		timeout: DefaultControlTimeout,
+	}, nil
+}
+
+func (c *ScanSourceClient) PollChanges(ctx context.Context, req *pluginv1.PollChangesRequest) (*pluginv1.PollChangesResponse, error) {
+	callCtx, cancel := ensureDeadline(ctx, c.timeout)
+	defer cancel()
+	return c.client.PollChanges(callCtx, req)
+}
+```
+
+- [ ] **Step 4: Run test to verify it passes**
+
+Run: `go test ./internal/pluginhost/ -run TestClientScanSourceRequiresCapability`
+Expected: PASS.
+
+- [ ] **Step 5: Commit**
+
+```bash
+git add internal/pluginhost/client.go internal/pluginhost/client_test.go
+git commit -m "feat(pluginhost): scan_source.v1 capability client wrapper"
+```
+
+---
+
+## Task 2: `plugins.Service` resolver for `scan_source.v1`
+
+**Files:**
+- Modify: `internal/plugins/service.go`
+
+- [ ] **Step 1: Add the resolver method**
+
+After `ScheduledTaskClient` (l.413–423), add the identical shape for scan source:
+
+```go
+func (s *Service) ScanSourceClient(
+	ctx context.Context,
+	installationID int,
+	capabilityID string,
+) (*pluginhost.ScanSourceClient, error) {
+	client, err := s.ensureClient(ctx, installationID)
+	if err != nil {
+		return nil, err
+	}
+	return client.ScanSource(capabilityID)
+}
+```
+
+- [ ] **Step 2: Build to verify it compiles**
+
+Run: `go build ./internal/plugins/`
+Expected: exits 0.
+
+- [ ] **Step 3: Commit**
+
+```bash
+git add internal/plugins/service.go
+git commit -m "feat(plugins): expose scan_source.v1 client resolver"
+```
+
+---
+
+## Task 3: Schema — `autoscan_connections` + `autoscan_sources`
+
+**Files:**
+- Create: `migrations/172_autoscan_v2.up.sql`, `migrations/172_autoscan_v2.down.sql`
+
+- [ ] **Step 1: Write the up migration**
+
+Create `migrations/172_autoscan_v2.up.sql`. It drops PR #43's `171` tables and creates the decoupled schema (no FK into `request_integrations`; the optional reuse link is `ON DELETE SET NULL`):
+
+```sql
+DROP TABLE IF EXISTS public.autoscan_sources;
+DROP TABLE IF EXISTS public.autoscan_settings;
+
+CREATE TABLE public.autoscan_settings (
+    id boolean PRIMARY KEY DEFAULT true,
+    enabled boolean NOT NULL DEFAULT false,
+    default_poll_interval_seconds integer NOT NULL DEFAULT 600,
+    debounce_seconds integer NOT NULL DEFAULT 60,
+    created_at timestamptz NOT NULL DEFAULT now(),
+    updated_at timestamptz NOT NULL DEFAULT now(),
+    CONSTRAINT autoscan_settings_singleton CHECK (id),
+    CONSTRAINT autoscan_settings_interval_pos CHECK (default_poll_interval_seconds > 0),
+    CONSTRAINT autoscan_settings_debounce_nonneg CHECK (debounce_seconds >= 0)
+);
+INSERT INTO public.autoscan_settings (id) VALUES (true) ON CONFLICT (id) DO NOTHING;
+
+CREATE TABLE public.autoscan_connections (
+    id uuid PRIMARY KEY DEFAULT gen_random_uuid(),
+    name text NOT NULL,
+    kind text NOT NULL,
+    -- Own credentials (used when request_integration_id IS NULL):
+    base_url text,
+    api_key_ref text,
+    -- Optional soft reuse of a Requests arr server (live link; SET NULL on delete):
+    request_integration_id text REFERENCES public.request_integrations(id) ON DELETE SET NULL,
+    created_at timestamptz NOT NULL DEFAULT now(),
+    updated_at timestamptz NOT NULL DEFAULT now(),
+    CONSTRAINT autoscan_connections_source_present
+        CHECK (request_integration_id IS NOT NULL OR base_url IS NOT NULL)
+);
+
+CREATE TABLE public.autoscan_sources (
+    id uuid PRIMARY KEY DEFAULT gen_random_uuid(),
+    installation_id integer NOT NULL,
+    capability_id text NOT NULL,
+    connection_id uuid NOT NULL REFERENCES public.autoscan_connections(id) ON DELETE RESTRICT,
+    enabled boolean NOT NULL DEFAULT false,
+    poll_interval_seconds integer,
+    marker text,
+    last_run_at timestamptz,
+    last_error text,
+    created_at timestamptz NOT NULL DEFAULT now(),
+    updated_at timestamptz NOT NULL DEFAULT now(),
+    CONSTRAINT autoscan_sources_interval_pos CHECK (poll_interval_seconds IS NULL OR poll_interval_seconds > 0),
+    CONSTRAINT autoscan_sources_capability_unique UNIQUE (installation_id, capability_id)
+);
+```
+
+- [ ] **Step 2: Write the down migration**
+
+Create `migrations/172_autoscan_v2.down.sql`:
+
+```sql
+DROP TABLE IF EXISTS public.autoscan_sources;
+DROP TABLE IF EXISTS public.autoscan_connections;
+DROP TABLE IF EXISTS public.autoscan_settings;
+```
+
+(Recreating the `171` tables on down-migration is unnecessary: `171` is unreleased and superseded; the down simply removes `172`'s tables.)
+
+- [ ] **Step 3: Apply and verify against a disposable DB**
+
+Run the migrations against a throwaway Postgres (the project's disposable-DB pattern) and confirm boot applies cleanly:
+```bash
+docker compose up -d postgres
+go run ./cmd/silo --migrate-only 2>&1 | grep -i "migrations applied" || echo "check migration output"
+```
+Expected: migrations apply without error; `\d autoscan_connections` shows the soft FK `request_integration_id`.
+
+- [ ] **Step 4: Commit**
+
+```bash
+git add migrations/172_autoscan_v2.up.sql migrations/172_autoscan_v2.down.sql
+git commit -m "feat(migrations): autoscan v2 schema (connections + sources, no requests FK)"
+```
+
+---
+
+## Task 4: Types and repository
+
+**Files:**
+- Rewrite: `internal/autoscan/types.go`
+- Rewrite: `internal/autoscan/repository.go`
+
+- [ ] **Step 1: Define the types**
+
+Replace `internal/autoscan/types.go` with the v2 model:
+
+```go
+package autoscan
+
+import "time"
+
+type Settings struct {
+	Enabled                    bool
+	DefaultPollIntervalSeconds int
+	DebounceSeconds            int
+}
+
+// Connection is an arr server the host can reach: either own credentials, or a
+// live reference to a Requests integration (RequestIntegrationID set).
+type Connection struct {
+	ID                   string
+	Name                 string
+	Kind                 string
+	BaseURL              string // own; empty when linked
+	APIKeyRef            string // own; empty when linked
+	RequestIntegrationID *string
+}
+
+// Source ties a scan_source plugin capability instance to a connection plus the
+// host-owned scheduling/bookkeeping state.
+type Source struct {
+	ID                  string
+	InstallationID      int
+	CapabilityID        string
+	ConnectionID        string
+	Enabled             bool
+	PollIntervalSeconds *int    // nil => use settings default
+	Marker              *string // opaque; nil on first run
+	LastRunAt           *time.Time
+	LastError           *string
+}
+```
+
+- [ ] **Step 2: Write a failing repository test**
+
+Add `internal/autoscan/repository_test.go` exercising round-trip + `AdvanceMarker` against a disposable DB (gate with the project's DB-test build tag/helper if one exists; otherwise a `//go:build integration` tag matching sibling DB tests). Minimal:
+
+```go
+func TestRepositoryMarkerRoundTrip(t *testing.T) {
+	repo := newTestRepo(t) // disposable-DB helper used by sibling repo tests
+	connID := repo.mustCreateConnection(t, Connection{Name: "Sonarr", Kind: "sonarr", BaseURL: "http://x", APIKeyRef: "k"})
+	srcID := repo.mustCreateSource(t, Source{InstallationID: 1, CapabilityID: "arr", ConnectionID: connID, Enabled: true})
+
+	if err := repo.AdvanceMarker(ctx, srcID, "2026-06-02T14:10:00Z"); err != nil {
+		t.Fatalf("AdvanceMarker: %v", err)
+	}
+	got, _ := repo.ListEnabledSources(ctx)
+	if len(got) != 1 || got[0].Marker == nil || *got[0].Marker != "2026-06-02T14:10:00Z" {
+		t.Fatalf("marker not persisted: %+v", got)
+	}
+}
+```
+
+- [ ] **Step 3: Run to verify it fails**
+
+Run: `go test ./internal/autoscan/ -run TestRepositoryMarkerRoundTrip` (with the DB helper available)
+Expected: FAIL — undefined repository methods.
+
+- [ ] **Step 4: Implement the repository**
+
+Rewrite `internal/autoscan/repository.go` with: `GetSettings`, `UpdateSettings`, connection CRUD (`CreateConnection`, `UpdateConnection`, `DeleteConnection`, `ListConnections`, `GetConnection`), source CRUD (`UpsertSource`, `ListEnabledSources`, `ListSources`, `GetSource`), and `AdvanceMarker(ctx, sourceID, marker string)` (sets `marker`, `last_run_at = now()`, clears `last_error`). Use pgx; follow the column/scan style of the existing (pre-rewrite) `repository.go` and `internal/requests/repository.go`.
+
+- [ ] **Step 5: Run to verify it passes**
+
+Run: `go test ./internal/autoscan/ -run TestRepositoryMarkerRoundTrip`
+Expected: PASS.
+
+- [ ] **Step 6: Commit**
+
+```bash

+## Task 6: Provider seam over the plugin resolver
+
+**Files:**
+- Create: `internal/autoscan/provider.go`
+
+- [ ] **Step 1: Define the seam and adapter**
+
+The engine must be testable without a live plugin, so it depends on a narrow interface, with a production adapter over `plugins.Service.ScanSourceClient`. Create `internal/autoscan/provider.go`:
+
+```go
+package autoscan
+
+import (
+	"context"
+
+	pluginv1 "github.com/Silo-Server/silo-plugin-sdk/pkg/pluginproto/silo/plugin/v1"

+// ScanSourceProvider yields changed paths for one source. The engine calls
+// PollChanges; production wraps the plugins.Service scan_source resolver.

+
+// pluginScanSourceClient is the slice of *pluginhost.ScanSourceClient used here.
+type pluginScanSourceClient interface {

+
+Note: the connection (`conn`) is delivered to the plugin out-of-band as runtime config when the source is configured (the plugin reads its own `{base_url, api_key}`); it is passed here so a future provider variant could inject per-call. For v1 the production path configures the plugin instance with the resolved connection at upsert time; document this in `NewPluginProvider`'s comment.

+
+## Task 7: Generalize the engine (`Service.PollOnce`)
+
+**Files:**
+- Rewrite: `internal/autoscan/service.go`
+- Modify: `internal/autoscan/service_test.go` (generalize the salvaged tests)
+
+- [ ] **Step 1: Adapt the salvaged tests to the provider seam**
+
+The PR #43 `service_test.go` used a `fakeHistory`; replace it with a `fakeProvider` implementing `ScanSourceProvider`, keeping the same assertions (dedupe to one folder; distinct paths same folder → two scans; disabled no-op; provider error keeps marker; enqueue failure releases claims + keeps marker). Add an opaque-marker assertion: the provider's returned `nextMarker` is stored verbatim via `AdvanceMarker`.
+
+```go
+type fakeProvider struct {
+	paths      map[string][]string // key: capabilityID
+	nextMarker string
+	err        error
+}
+
+func (f *fakeProvider) PollChanges(_ context.Context, _ int, capabilityID, _ string, _ ResolvedConnection) ([]string, string, error) {
+	if f.err != nil {
+		return nil, "", f.err
+	}
+	return f.paths[capabilityID], f.nextMarker, nil
+}
+```
+
+- [ ] **Step 2: Run to verify the tests fail**
+
+Run: `go test ./internal/autoscan/ -run TestPollOnce`
+Expected: FAIL — `Service` signature/`fakeProvider` not yet wired.
+
+- [ ] **Step 3: Rewrite the engine**
+
+Rewrite `internal/autoscan/service.go`. Keep the salvaged resolve→suppress→enqueue loop verbatim (it is provider-agnostic already), but drive it from sources + the provider seam:
+
+```go
+func (s *Service) PollOnce(ctx context.Context) error {
+	settings, err := s.store.GetSettings(ctx)
+	if err != nil {
+		return err
+	}
+	if !settings.Enabled {
+		return nil
+	}
+	sources, err := s.store.ListEnabledSources(ctx)
+	if err != nil {
+		return err
+	}
+	ttl := time.Duration(settings.DebounceSeconds) * time.Second
+
+	for _, src := range sources {
+		conn, cerr := s.resolveConnection(ctx, src.ConnectionID)
+		if cerr != nil {
+			slog.WarnContext(ctx, "autoscan: resolve connection failed", "source_id", src.ID, "err", cerr)
+			continue
+		}
+		marker := ""
+		if src.Marker != nil {
+			marker = *src.Marker
+		}
+		paths, next, perr := s.provider.PollChanges(ctx, src.InstallationID, src.CapabilityID, marker, conn)
+		if perr != nil {
+			slog.WarnContext(ctx, "autoscan: poll changes failed", "source_id", src.ID, "err", perr)
+			_ = s.store.RecordError(ctx, src.ID, perr.Error())
+			continue
+		}
+
+		targets, claimed := s.resolveAndClaim(ctx, paths, ttl) // salvaged dedupe→resolve→suppress
+		if len(targets) > 0 {
+			if eerr := s.queue.EnqueueScans(ctx, targets); eerr != nil {
+				s.releaseClaims(ctx, claimed)
+				slog.WarnContext(ctx, "autoscan: enqueue failed", "source_id", src.ID, "err", eerr)
+				continue // do NOT advance marker
+			}
+		}
+		if aerr := s.store.AdvanceMarker(ctx, src.ID, next); aerr != nil {
+			slog.WarnContext(ctx, "autoscan: advance marker failed", "source_id", src.ID, "err", aerr)
+		}
+	}
+	return nil
+}
+```
+
+Extract the salvaged loop body into `resolveAndClaim`/`releaseClaims` helpers (lifted verbatim from PR #43's `service.go` lines that build `targets`/`claimed`). Keep `uniqueParentDirs`, `Suppressor`, the `fmt.Sprintf("%d|%s", folderID, target.Path)` suppression key, and the `scantrigger.RequestError` quiet-skip.

+## Task 8: Delete arr-specific salvage residue
+
+**Files:**
+- Delete: `internal/autoscan/history.go`, `history_test.go`, `rewrite.go`, `rewrite_test.go`, `suggest.go`, `suggest_deps.go`, `suggest_test.go`
+
+- [ ] **Step 1: Remove the files**
+
+```bash

+       internal/autoscan/suggest.go internal/autoscan/suggest_deps.go internal/autoscan/suggest_test.go
+```
+
+- [ ] **Step 2: Build to confirm no remaining references**
+
+Run: `go build ./internal/autoscan/...`
+Expected: exits 0 (the engine no longer references the deleted arr logic). If it fails, a reference was missed — remove it.
+
+- [ ] **Step 3: Commit**
+
+```bash
+git commit -m "refactor(autoscan): drop arr-specific history/rewrite/suggest (moved to plugin)"

+
+## Task 9: Admin API rewrite
+
+**Files:**
+- Rewrite: `internal/api/handlers/autoscan.go`
+- Modify: `internal/api/handlers/autoscan_test.go`
+
+- [ ] **Step 1: Define the endpoints**
+
+Rewrite the handler to back the new model. Endpoints (admin-gated, mounted in Task 10):
+- `GET/PUT /admin/autoscan/settings`
+- `GET/POST /admin/autoscan/connections`, `PUT/DELETE /admin/autoscan/connections/{id}`
+- `GET /admin/autoscan/sources`, `PUT /admin/autoscan/sources/{id}` (enable, interval, connection binding)
+- `POST /admin/autoscan/trigger` (async `PollOnce`, 202 — keep the detached-goroutine + channel-tested pattern from the closed PR's `autoscan_test.go`)
+- `GET /admin/autoscan/status`
+
+Strip credentials from responses (never emit `api_key_ref`/resolved keys), matching the `_SENSITIVE_METADATA_KEYS` defense-in-depth posture.
+
+- [ ] **Step 2: Port + extend the handler tests**
+
+Carry over the trigger test (the `done`-channel synchronization fix from `d3ee373`), the FK→404 test (now: unknown source/connection → 404), and a secrets-not-leaked test for the connections list.
+
+- [ ] **Step 3: Run the handler tests (libvips container)**
+
+Run (in the libvips-equipped container per Prerequisites #3):
+`go test ./internal/api/handlers/ -run Autoscan`
+Expected: PASS.
+
+- [ ] **Step 4: Commit**
+
+```bash
+git add internal/api/handlers/autoscan.go internal/api/handlers/autoscan_test.go
+git commit -m "feat(api): autoscan v2 admin endpoints (settings, connections, sources)"
+```
+
+---
+
+## Task 10: Wiring + rate limits + retire old coupling
+
+**Files:**
+- Modify: `internal/api/router.go`
+- Modify: `cmd/silo/main.go`
+
+- [ ] **Step 1: Rebuild the service wiring**
+
+In `internal/api/router.go` and `cmd/silo/main.go`, construct the v2 service:
+
+```go
+autoscanRepo := autoscan.NewRepository(deps.DB)
+provider := autoscan.NewPluginProvider(pluginServiceScanSourceAdapter{pluginService})
+connResolver := autoscan.NewConnectionResolver(requestIntegrationLookup{requestsRepo}, serverSettingsSecretResolver{settingsRepo})
+autoscanSvc := autoscan.NewService(autoscanRepo, provider, connResolver, deps.Resolver, deps.ScanQueue, autoscan.NewRedisSuppressor(deps.RedisClient))
+autoscanHandler = handlers.NewAutoscanHandler(autoscanRepo, autoscanSvc)
+```
+
+Replace the old route block with the Task 9 routes. Keep the `catalog_*`/admin rate-limit conventions consistent with the security standards (per-user/admin caps on the new endpoints; mirror the request-integrations admin tier).
+
+- [ ] **Step 2: Retarget the poll task**
+
+`internal/taskmanager/tasks/autoscan_poll.go` calls `Service.PollOnce` — unchanged behavior; confirm it compiles against the rebuilt service and uses `Settings.DefaultPollIntervalSeconds` for the interval (per-source overrides are honored inside `PollOnce`).
+
+- [ ] **Step 3: Build the whole tree**
+
+Run (libvips container): `go build ./...`
+Expected: exits 0.
+
+- [ ] **Step 4: Commit**
+
+```bash
+git add internal/api/router.go cmd/silo/main.go internal/taskmanager/tasks/autoscan_poll.go
+git commit -m "feat(autoscan): wire v2 service, routes, and poll task"
+```
+

+
+## Task 11: Full sweep + finalize SDK dependency
+
+**Files:**
+- Modify: `go.mod`, `go.sum`
+
+- [ ] **Step 1: Full build + test (libvips container)**
+
+Run in the libvips-equipped container (Prerequisites #3):
+```bash
+go build ./... && go test ./... && go vet ./...
+```
+Expected: build OK; all packages `ok`; vet clean. `gofmt -l internal migrations` prints nothing.
+
+- [ ] **Step 2: Finalize the SDK version (after `v0.5.0` is tagged upstream)**
+
+Once `silo-plugin-sdk` PR #2 is merged and `v0.5.0` tagged:
+```bash
+go mod edit -dropreplace github.com/Silo-Server/silo-plugin-sdk
+go get github.com/Silo-Server/silo-plugin-sdk@v0.5.0
+go mod tidy
+go build ./...
+```
+Expected: builds against the released tag with no replace directive.
+
+If `v0.5.0` is not yet tagged when this plan is otherwise complete, leave the replace directive in place, commit it, and note in the PR that the dependency must be finalized before merge (do not merge a `replace` pointing at a local path).
+
+- [ ] **Step 3: Commit**
+
+```bash
+git add go.mod go.sum
+git commit -m "build: depend on silo-plugin-sdk v0.5.0 (scan_source.v1)"
+```
+
+---
+
+## Self-Review notes
+
+- **Spec coverage:** §7 engine (Tasks 6–7), §8 connections incl. reuse-or-own + soft Requests link (Tasks 3,5), §9 data model decoupled from Requests + Autoscan-owned state (Tasks 3–4,9–10), §5/§11 host consumes `scan_source.v1` (Tasks 1–2). §10 (arr plugin) and §9 UI are separate plans.
+- **Salvage map honored (§13):** engine/dedupe/suppress kept and generalized (Tasks 6–8); arr history/rewrite/suggest deleted (Task 8); `last_poll_at` → opaque `marker` (Tasks 3–4,7).
+- **Out of scope here:** the Autoscan admin **UI** category (Part 2 plan) and the **arr plugin** (separate repo plan). This backend is testable on its own via the repository/engine/handler tests.
+- **Risk carried from spec §14:** plugin multiplicity (one installation per arr server vs. many connections per installation) is modeled as one `autoscan_sources` row per `(installation_id, capability_id)`; if the runtime supports multiple capability instances per installation this maps cleanly, otherwise it implies one installation per server. Confirm during Task 1–2 by inspecting `ensureClient`/installation handling.
+- **Type consistency:** `ResolvedConnection{BaseURL,APIKey}`, `Connection{BaseURL,APIKeyRef,RequestIntegrationID}`, `Source{InstallationID,CapabilityID,ConnectionID,Marker}`, `ScanSourceProvider.PollChanges(...)`, `Service.PollOnce` used consistently across Tasks 4–10.

+# Autoscan Rewrite-Sync Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** A "Sync rewrites from arr" action that suggests autoscan `path_rewrites` for an instance by matching its arr root folders to Silo media folders on shared trailing path segments, previewed and committed by the admin.
+
+**Architecture:** A pure `suggestRewrites` matcher in `internal/autoscan`, a `Service.SuggestRewrites` method backed by two new injected deps (an arr root-folder client and a Silo folder lister), one read-only admin endpoint returning a preview, and a "Sync from arr" button in the existing Autoscan tab that merges proposals into the editor (admin saves via the existing per-source PUT). Manual rewrites stay the source of truth.
+
+**Tech Stack:** Go (standard `testing`), React/TypeScript.
+
+**Spec:** `docs/superpowers/specs/2026-06-02-autoscan-rewrite-sync-design.md`
+
+**Commands assume the repository root is the cwd.** Go tests: `go test ./internal/autoscan/...`. Frontend: `cd web && pnpm exec tsc -b && pnpm run lint`. Ensure the Go toolchain is on `PATH` (prepend its `bin` directory if `go` is missing). `internal/api`/`internal/api/handlers` cannot be compiled without libvips; verify those via `gofmt` + the Docker build.

+- [ ] **Step 3.1: Implement the two adapters + interfaces**
+```go
+package autoscan
+
+import (
+	"context"
+	"net/http"
+
+	"github.com/Silo-Server/silo-server/internal/catalog"
+	"github.com/Silo-Server/silo-server/internal/requests/arrclient"
+)
+
+// RootFolderClient lists a Radarr/Sonarr instance's configured root folder paths.
+type RootFolderClient interface {
+	RootFolders(ctx context.Context, baseURL, apiKey string) ([]string, error)
+}
+
+// FolderLister lists every Silo media-folder path.
+type FolderLister interface {
+	ListFolderPaths(ctx context.Context) ([]string, error)
+}
+
+type arrRootFolderClient struct{ httpClient *http.Client }
+
+// NewArrRootFolderClient returns a RootFolderClient backed by the shared arrclient.
+func NewArrRootFolderClient(httpClient *http.Client) RootFolderClient {
+	return &arrRootFolderClient{httpClient: httpClient}
+}
+
+func (c *arrRootFolderClient) RootFolders(ctx context.Context, baseURL, apiKey string) ([]string, error) {
+	client := arrclient.New(baseURL, apiKey, c.httpClient)
+	folders, err := arrclient.ListRootFolders(ctx, client)
+	if err != nil {
+		return nil, err
+	}
+	paths := make([]string, 0, len(folders))
+	for _, f := range folders {
+		if f.Path != "" {
+			paths = append(paths, f.Path)
+		}
+	}
+	return paths, nil
+}
+
+type catalogFolderLister struct{ repo *catalog.FolderRepository }
+
+// NewCatalogFolderLister adapts catalog.FolderRepository to FolderLister.
+func NewCatalogFolderLister(repo *catalog.FolderRepository) FolderLister {
+	return &catalogFolderLister{repo: repo}
+}
+
+func (l *catalogFolderLister) ListFolderPaths(ctx context.Context) ([]string, error) {

+	}
+	var paths []string
+	for _, f := range folders {
+		paths = append(paths, f.Paths...)
+	}
+	return paths, nil
+}
+```
+Note: `autoscan` already depends on `catalog` (via `scantrigger`) and on `requests/arrclient` (via `history.go`), so these imports add no new module-level coupling and no cycle (`catalog` does not import `autoscan`).
+
+- [ ] **Step 3.2: Build + commit**
+
+```bash
+go build ./internal/autoscan/...
+git add internal/autoscan/suggest_deps.go

+```
+
+### Task 4: Service.SuggestRewrites
+
+**Files:**
+- Modify: `internal/autoscan/service.go`
+- Modify: `internal/autoscan/service_test.go`
+
+- [ ] **Step 4.1: Write the failing test** (append to `service_test.go`):
+```go
+type fakeRootFolders struct {
+	paths []string
+	err   error
+}
+
+func (f fakeRootFolders) RootFolders(context.Context, string, string) ([]string, error) {
+	return f.paths, f.err

+	}
+	if len(got.Unmatched) != 1 || got.Unmatched[0] != "/data/Movies" {
+		t.Fatalf("unmatched=%+v", got.Unmatched)
+	}
+}
+```
+> The `Store` interface needs a `GetSource` method so the service can call it. Add `GetSource(ctx context.Context, integrationID string) (*Source, error)` to the `Store` interface in `service.go`. `*Repository` already implements it (Task 2). The test's `sourceGetterStore` embeds the existing `fakeStore` and adds `GetSource`. If `fakeStore` does not satisfy the widened interface on its own, that's fine — only `sourceGetterStore` is used here; but ensure the package still compiles (other tests construct `fakeStore` directly and pass it where `Store` is required — add a `GetSource` method to `fakeStore` returning `(nil, nil)` so it still satisfies `Store`).
+
+- [ ] **Step 4.2: Run it — expect failure**
+
+```bash
+go test ./internal/autoscan/ -run TestSuggestRewritesService -v
+```
+Expected: FAIL (`SetRewriteResolvers`/`SuggestRewrites` undefined).
+
+- [ ] **Step 4.3: Implement** in `service.go`. Add fields + setter + method, and add `GetSource` to `Store`:
+```go
+// add to the Store interface:
+//   GetSource(ctx context.Context, integrationID string) (*Source, error)
+
+// add fields to Service struct:
+//   rootFolders RootFolderClient
+//   folders     FolderLister
+
+// SetRewriteResolvers wires the deps used by SuggestRewrites (optional; only the
+// admin-facing service needs them).
+func (s *Service) SetRewriteResolvers(rootFolders RootFolderClient, folders FolderLister) {
+	s.rootFolders = rootFolders
+	s.folders = folders
+}
+
+// SuggestRewrites matches an instance's arr root folders to Silo media folders.
+func (s *Service) SuggestRewrites(ctx context.Context, integrationID string) (RewriteSuggestions, error) {
+	if s.rootFolders == nil || s.folders == nil {
+		return RewriteSuggestions{}, fmt.Errorf("autoscan: rewrite suggestion not configured")
+	}
+	src, err := s.store.GetSource(ctx, integrationID)
+	if err != nil {
+		return RewriteSuggestions{}, err
+	}
+	apiKey := src.APIKeyRef
+	if s.secrets != nil && apiKey != "" {
+		if resolved, rerr := s.secrets.Get(ctx, apiKey); rerr == nil && resolved != "" {
+			apiKey = resolved
+		}
+	}
+	arrRoots, err := s.rootFolders.RootFolders(ctx, src.BaseURL, apiKey)
+	if err != nil {
+		return RewriteSuggestions{}, fmt.Errorf("autoscan: list arr root folders: %w", err)
+	}
+	siloPaths, err := s.folders.ListFolderPaths(ctx)
+	if err != nil {
+		return RewriteSuggestions{}, fmt.Errorf("autoscan: list silo folders: %w", err)
+	}
+	return suggestRewrites(arrRoots, siloPaths, src.PathRewrites), nil
+}
+```
+Add `GetSource` to `fakeStore` in `service_test.go` (`func (f *fakeStore) GetSource(context.Context, string) (*Source, error) { return nil, nil }`).
+
+- [ ] **Step 4.4: Run tests — expect pass; commit**
+
+```bash
+go test ./internal/autoscan/...
+gofmt -l internal/autoscan/service.go internal/autoscan/service_test.go

+```
+
+---
+
+## Phase 3 — API endpoint
+
+### Task 5: Handler + route
+
+**Files:**
+- Modify: `internal/api/handlers/autoscan.go`
+- Modify: `internal/api/router.go`
+- Modify: `internal/api/handlers/autoscan_test.go`
+
+- [ ] **Step 5.1: Extend the handler's service interface + add the handler method**
+
+In `autoscan.go`, add `SuggestRewrites` to the `autoscanTriggerer` interface:
+```go
+type autoscanTriggerer interface {
+	PollOnce(ctx context.Context) error
+	SuggestRewrites(ctx context.Context, integrationID string) (autoscan.RewriteSuggestions, error)
+}
+```
+Add the handler:
+```go
+func (h *AutoscanHandler) HandleRewriteSuggestions(w http.ResponseWriter, r *http.Request) {
+	id := strings.TrimSpace(chi.URLParam(r, "id"))
+	suggestions, err := h.svc.SuggestRewrites(r.Context(), id)
+	if err != nil {
+		if errors.Is(err, autoscan.ErrIntegrationNotFound) {
+			writeError(w, http.StatusNotFound, "not_found", "Autoscan source not found")
+			return
+		}
+		// arr unreachable / bad key / folder list failure
+		writeError(w, http.StatusBadGateway, "arr_unreachable", "Could not load root folders from the arr instance")
+		return
+	}
+	writeJSON(w, http.StatusOK, suggestions)
+}
+```
+(`errors`, `autoscan`, `chi`, `strings`, `writeError`, `writeJSON` already imported.)
+
+- [ ] **Step 5.2: Mount the route** in `router.go`, inside the autoscan route block:
+```go
+r.Get("/autoscan/sources/{id}/rewrite-suggestions", autoscanHandler.HandleRewriteSuggestions)
+```
+
+- [ ] **Step 5.3: Wire the service deps** in `router.go` where `autoscanSvc` is built (after `autoscan.NewService(...)`):
+```go
+autoscanSvc.SetRewriteResolvers(
+	autoscan.NewArrRootFolderClient(nil),
+	autoscan.NewCatalogFolderLister(deps.FolderRepo),
+)
+```
+(This is inside the existing `if deps.FolderRepo != nil && deps.LibraryScanQueue != nil` block, so `deps.FolderRepo` is non-nil here.)
+
+- [ ] **Step 5.4: Update the handler test fake**
+
+In `autoscan_test.go`, the fake satisfying `autoscanTriggerer` (e.g. `fakeAutoscanTriggerer`) gains:
+```go
+func (f *fakeAutoscanTriggerer) SuggestRewrites(context.Context, string) (autoscan.RewriteSuggestions, error) {
+	return autoscan.RewriteSuggestions{}, nil
+}
+```
+Add a test asserting `HandleRewriteSuggestions` returns 200 with JSON for a known id (mirror the existing handler tests).
+
+- [ ] **Step 5.5: Verify (limited) + commit**
+
+```bash
+# ensure the Go toolchain is on PATH
+go vet ./internal/autoscan/...
+gofmt -l internal/api/handlers/autoscan.go internal/api/router.go internal/api/handlers/autoscan_test.go
+# internal/api cannot compile here (libvips) — Docker verifies later.
+git add internal/api/handlers/autoscan.go internal/api/router.go internal/api/handlers/autoscan_test.go
+git commit -m "feat(autoscan): rewrite-suggestions endpoint"
+```
+
+---
+
+## Phase 4 — Frontend
+
+### Task 6: Types + hook
+
+**Files:**
+- Modify: `web/src/api/types.ts`
+- Modify: `web/src/hooks/queries/useAutoscan.ts`
+
+- [ ] **Step 6.1: Types** — add to `types.ts`:
+```ts
+export interface AutoscanProposedRewrite {
+  from: string;
+  to: string;
+  match_depth: number;
+}
+export interface AutoscanAmbiguousRoot {
+  root: string;
+  candidates: string[];
+}
+export interface AutoscanRewriteSuggestions {
+  proposed: AutoscanProposedRewrite[];
+  unmatched: string[];
+  ambiguous: AutoscanAmbiguousRoot[];
+  covered: string[];
+}
+```
+
+- [ ] **Step 6.2: Hook** — add to `useAutoscan.ts` a mutation that fetches suggestions for an id:
+```ts
+export function useAutoscanRewriteSuggestions() {
+  return useMutation({
+    mutationFn: (id: string) =>
+      api<AutoscanRewriteSuggestions>(`/admin/autoscan/sources/${id}/rewrite-suggestions`),
+    onError: (err) =>
+      toast.error(err instanceof Error ? err.message : "Could not sync rewrites from the arr instance"),
+  });
+}
+```
+Match the import/`api`/`toast`/`useMutation` conventions already in the file (it imports `api` and `toast` already; reuse them; import the new type).
+
+- [ ] **Step 6.3: Lint + commit**
+
+```bash
+cd web && pnpm exec tsc -b && pnpm run lint && pnpm exec prettier --check src/api/types.ts src/hooks/queries/useAutoscan.ts
+git add web/src/api/types.ts web/src/hooks/queries/useAutoscan.ts
+git commit -m "feat(web): autoscan rewrite-suggestions types and hook"
+```
+
+### Task 7: Sync button + preview in AutoscanSourceEditor
+
+**Files:**
+- Modify: `web/src/pages/AdminRequests.tsx`
+
+- [ ] **Step 7.1: Add the button + preview**
+
+In `AutoscanSourceEditor`:
+- Call `const suggest = useAutoscanRewriteSuggestions();` and add local state `const [preview, setPreview] = useState<AutoscanRewriteSuggestions | null>(null);` and `const [selected, setSelected] = useState<Set<string>>(new Set());`.
+- Add a **"Sync from arr"** `Button` beside Save: `onClick={async () => { const s = await suggest.mutateAsync(source.integration_id); setPreview(s); setSelected(new Set(s.proposed.map((p) => p.from))); }}` (disabled while `suggest.isPending`).
+- When `preview` is set, render a panel (reuse the file's `Dialog` or an inline bordered panel) with three sections:
+  - **Proposed:** each `proposed[]` row — a checkbox bound to `selected.has(p.from)` (toggle updates the set), `from → to`, and a `Badge` showing confidence: `match_depth >= 2 ? "${match_depth} segments" : "1 segment — weak"` (destructive/secondary variant for weak).
+  - **Unmatched:** muted list of `unmatched[]` ("no Silo match — add manually if needed").
+  - **Ambiguous:** list of `ambiguous[]` (`root` + its `candidates` joined) — info only.
+  - An **"Add selected to rewrites"** button that merges the checked proposals into the editor's existing rewrites state, deduped by `from` (skip any whose `from` already exists), then `setPreview(null)`. Do NOT auto-save — the admin then clicks the existing **Save**.
+- Keep the existing manual path-rewrite editor unchanged; sync only appends rows to it.
+
+Reuse existing `Button`/`Badge`/`Field`/`Dialog` primitives and the editor's existing rewrites-state setter.
+
+- [ ] **Step 7.2: Lint + commit**
+
+```bash
+cd web && pnpm exec tsc -b && pnpm run lint && pnpm exec prettier --check src/pages/AdminRequests.tsx
+git add web/src/pages/AdminRequests.tsx
+git commit -m "feat(web): autoscan sync-rewrites preview"
+```
+
+---
+
+## Phase 5 — Verification
+
+### Task 8: Full verification
+
+- [ ] **Step 8.1: Go**
+
+```bash
+# ensure the Go toolchain is on PATH
+go test ./internal/autoscan/... 2>&1 | tail
+go vet ./internal/autoscan/...
+gofmt -l internal/autoscan internal/api/handlers/autoscan.go internal/api/router.go
+```
+Expected: all pass; vet/gofmt clean.
+
+- [ ] **Step 8.2: Frontend**
+
+```bash
+cd web && pnpm exec tsc -b && pnpm run lint && pnpm run format:check
+```
+
+- [ ] **Step 8.3: Docker build (closes the libvips gap)**
+
+```bash
+docker build --build-arg BUILD_REVISION=$(git rev-parse HEAD) --build-arg BUILD_DIRTY=false -t silo-server:autoscan .
+```
+Expected: exit 0 (handlers + router + frontend compile).
+
+- [ ] **Step 8.4: Smoke (optional)**
+
+On a deploy with arr instances configured: open an instance in the Autoscan tab, click **Sync from arr**, confirm the preview shows proposed (with confidence) + unmatched + ambiguous, "Add selected" appends deduped rows, and Save persists them.
+
+---
+
+## Self-review notes (resolved)
+
+- **Spec §1 matcher** → Task 1 (incl. normalization, covered-first, suffix depth, unlike-deployment fixtures). **§2 endpoint/service** → Tasks 2–5 (`GetSource`, `RootFolderClient`/`FolderLister`, `SuggestRewrites`, endpoint, 404/502 mapping). **§3 frontend** → Tasks 6–7. **§4 testing** → Tasks 1,4,5 + Task 8.
+- **Manual-preserving**: sync only *appends* deduped rows to the editor; the admin saves via the existing `PUT` (Task 7). Never auto-writes.
+- **Generic**: `suggestRewrites` takes plain string slices, no deployment constants; tests include `/data/Movies` and `/srv/tv` fixtures (Task 1).
+- **Optional deps**: `SetRewriteResolvers` keeps `main.go`'s poll service untouched; `SuggestRewrites` errors if unset (Task 4).
+- **Type consistency**: `RewriteSuggestions`/`ProposedRewrite`/`AmbiguousRoot` (Go) ↔ `AutoscanRewriteSuggestions`/`AutoscanProposedRewrite`/`AutoscanAmbiguousRoot` (TS); `match_depth` JSON tag matches.

+# `scan_source.v1` SDK Capability — Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Add a new, additive `scan_source.v1` plugin capability to `silo-plugin-sdk` so the Silo host can pull changed paths from a scan-source plugin on a timer.
+
+**Architecture:** Mirror the existing `scheduled_task.v1` capability exactly — a single-RPC, request/response gRPC service defined in a `.proto`, generated into `pkg/pluginproto`, then registered in three Go helper sites (`capability.KnownTypes`, the `runtime.CapabilityServers` struct, and the `runtime.GRPCPlugin` server registration). Nothing existing is modified in shape; only new symbols are added. Tag a new SDK release so the host and the arr plugin can build against it.
+
+**Tech Stack:** Go, Protocol Buffers (proto3), `buf` codegen (`buf.gen.yaml`), `google.golang.org/protobuf`, `google.golang.org/grpc`, the `hashicorp/go-plugin` runtime the SDK wraps.
+
+---
+
+## Prerequisites (read before starting)
+
+This plan targets the **`silo-plugin-sdk`** repository (Go module `github.com/Silo-Server/silo-plugin-sdk`), which is **not currently checked out** in this workspace — only `silo-server` and `silo-plugin-tmdb` are. Before executing:
+
+1. Clone `silo-plugin-sdk` as a writable working copy beside the other repos. Commands below assume **the silo-plugin-sdk repository root is the cwd**.
+2. Ensure the proto toolchain is available: the `make proto` target auto-installs `buf`, `protoc-gen-go@v1.36.11`, and `protoc-gen-go-grpc@v1.6.1` into `$(GO_BIN)`, but it requires the **`protoc`** binary to already be on `PATH` (it errors `protoc is required` otherwise). Install `protoc` if absent.
+3. This SDK is the **long pole**: the silo-server host plan and the arr-plugin plan both depend on the version tagged at the end of this plan (Task 6). Do not start those until this is tagged.
+
+**Pattern reference (current `scheduled_task.v1`, the template this mirrors):**
+- Proto: `proto/silo/plugin/v1/scheduled_task.proto`
+- Generated: `pkg/pluginproto/silo/plugin/v1/scheduled_task.pb.go` + `scheduled_task_grpc.pb.go`
+- Capability const + allowlist: `pkg/pluginsdk/capability/capability.go`
+- Runtime wiring: `pkg/pluginsdk/runtime/runtime.go` (struct field, `Client` accessor, `GRPCServer` registration)

+
+## Task 1: Define and generate the `scan_source.v1` proto
+
+**Files:**
+- Create: `proto/silo/plugin/v1/scan_source.proto`
+- Create (via codegen): `pkg/pluginproto/silo/plugin/v1/scan_source.pb.go`, `pkg/pluginproto/silo/plugin/v1/scan_source_grpc.pb.go`
+
+- [ ] **Step 1: Write the proto**
+
+Create `proto/silo/plugin/v1/scan_source.proto` (the `go_package` option must match the sibling protos exactly so generated code lands in package `pluginv1`):
+
+```proto
+syntax = "proto3";
+
+package silo.plugin.v1;
+
+option go_package = "github.com/Silo-Server/silo-plugin-sdk/pkg/pluginproto/silo/plugin/v1;pluginv1";
+
+// ScanSource lets the host pull changed filesystem paths from a provider
+// (e.g. Sonarr/Radarr, inotify, Ceph). Pull only: the host owns the timer and
+// calls PollChanges; the plugin never initiates.
+service ScanSource {
+  rpc PollChanges(PollChangesRequest) returns (PollChangesResponse);
+}
+
+message PollChangesRequest {
+  // Which configured scan_source capability instance is being polled.
+  string capability_id = 1;
+  // Opaque continuation token from the previous PollChanges. Empty on first
+  // run, which the provider treats as "start from now" (do not replay history).
+  string marker = 2;
+}
+
+message PollChangesResponse {
+  // Absolute paths already translated into Silo's filesystem namespace (the
+  // plugin has applied its own path rewrites). Files or directories.
+  repeated string changed_paths = 1;
+  // Opaque continuation token. The host stores it verbatim and echoes it back
+  // on the next PollChanges; the host never parses it.
+  string next_marker = 2;
+}
+```
+
+- [ ] **Step 2: Generate the Go code**
+
+Run: `make proto`
+Expected: exits 0; creates `pkg/pluginproto/silo/plugin/v1/scan_source.pb.go` and `scan_source_grpc.pb.go`. (If it prints `protoc is required`, install `protoc` and re-run.)
+
+- [ ] **Step 3: Verify the generated symbols exist and compile**
+
+Run: `go build ./... && grep -l "func NewScanSourceClient" pkg/pluginproto/silo/plugin/v1/scan_source_grpc.pb.go && grep -l "RegisterScanSourceServer" pkg/pluginproto/silo/plugin/v1/scan_source_grpc.pb.go`
+Expected: build succeeds; both `grep`s print the filename (confirming `ScanSourceClient`, `ScanSourceServer`, `NewScanSourceClient`, `RegisterScanSourceServer` were generated — `require_unimplemented_servers=false` in `buf.gen.yaml` means no forced `UnimplementedScanSourceServer` embedding).
+
+- [ ] **Step 4: Commit**
+
+```bash
+git add proto/silo/plugin/v1/scan_source.proto pkg/pluginproto/silo/plugin/v1/scan_source.pb.go pkg/pluginproto/silo/plugin/v1/scan_source_grpc.pb.go
+git commit -m "feat(proto): add scan_source.v1 capability service"
+```
+
+---
+
+## Task 2: Register the capability type in the allowlist
+
+The manifest loader rejects capability types not in `capability.KnownTypes` (see `TestLoadRejectsUnknownCapabilityType`). A manifest declaring `scan_source.v1` cannot load until the type is registered here.
+
+**Files:**
+- Modify: `pkg/pluginsdk/capability/capability.go`
+- Create or Modify: `pkg/pluginsdk/capability/capability_test.go`
+
+- [ ] **Step 1: Write the failing test**
+
+Append to `pkg/pluginsdk/capability/capability_test.go` (create the file with this `package capability` header if it does not exist):
+
+```go
+package capability
+
+import "testing"
+
+func TestScanSourceIsKnownType(t *testing.T) {
+	if ScanSource != "scan_source.v1" {
+		t.Fatalf("ScanSource const = %q, want %q", ScanSource, "scan_source.v1")
+	}
+	found := false
+	for _, k := range KnownTypes {
+		if k == ScanSource {
+			found = true
+			break
+		}
+	}
+	if !found {
+		t.Fatalf("ScanSource (%q) missing from KnownTypes %v", ScanSource, KnownTypes)
+	}
+}
+```
+
+- [ ] **Step 2: Run test to verify it fails**
+
+Run: `go test ./pkg/pluginsdk/capability/ -run TestScanSourceIsKnownType -v`
+Expected: FAIL — `undefined: ScanSource` (the const does not exist yet).
+
+- [ ] **Step 3: Add the const and allowlist entry**
+
+In `pkg/pluginsdk/capability/capability.go`, add the const inside the existing `const (...)` block (after `EbookBackend`):
+
+```go
+	EbookBackend     = "ebook_backend.v1"
+	ScanSource       = "scan_source.v1"
+```
+
+and add it to the `KnownTypes` slice (append `ScanSource` to the existing list):
+
+```go
+	ScanSource,
+```
+
+- [ ] **Step 4: Run test to verify it passes**
+
+Run: `go test ./pkg/pluginsdk/capability/ -run TestScanSourceIsKnownType -v`
+Expected: PASS.
+
+- [ ] **Step 5: Commit**
+
+```bash
+git add pkg/pluginsdk/capability/capability.go pkg/pluginsdk/capability/capability_test.go
+git commit -m "feat(capability): register scan_source.v1 as a known capability type"
+```
+
+---
+
+## Task 3: Wire the capability into the runtime
+
+Add the `ScanSource` server to `CapabilityServers`, a `Client.ScanSource()` accessor, and the conditional registration in `GRPCServer` — mirroring `ScheduledTask` in `pkg/pluginsdk/runtime/runtime.go`.
+
+**Files:**
+- Modify: `pkg/pluginsdk/runtime/runtime.go`
+- Create or Modify: `pkg/pluginsdk/runtime/runtime_test.go`

+- [ ] **Step 1: Write the failing test**
+
+Append to `pkg/pluginsdk/runtime/runtime_test.go` (create with the `package runtime` header if absent). This test constructs a real `*grpc.Server`, supplies a minimal `ScanSource` server, and asserts `GRPCServer` registers it without error:
+
+```go
+package runtime
+
+import (
+	"context"
+	"testing"
+
+	pluginv1 "github.com/Silo-Server/silo-plugin-sdk/pkg/pluginproto/silo/plugin/v1"
+	"google.golang.org/grpc"
+)
+
+type stubScanSource struct{}
+
+func (stubScanSource) PollChanges(context.Context, *pluginv1.PollChangesRequest) (*pluginv1.PollChangesResponse, error) {
+	return &pluginv1.PollChangesResponse{}, nil
+}
+
+func TestGRPCServerRegistersScanSource(t *testing.T) {
+	p := &GRPCPlugin{Servers: CapabilityServers{
+		Runtime:    stubRuntime{},   // existing stub used by sibling runtime tests
+		ScanSource: stubScanSource{},
+	}}
+	srv := grpc.NewServer()
+	if err := p.GRPCServer(nil, srv); err != nil {
+		t.Fatalf("GRPCServer with ScanSource = %v, want nil", err)
+	}
+	if _, ok := srv.GetServiceInfo()["silo.plugin.v1.ScanSource"]; !ok {
+		t.Fatalf("ScanSource service not registered; got %v", srv.GetServiceInfo())
+	}
+}
+```
+
+Note: `GRPCServer` requires `Servers.Runtime` to be non-nil (it errors otherwise). Reuse the existing runtime stub the sibling tests use. If no such stub exists in `runtime_test.go`, add a minimal one:
+
+```go
+type stubRuntime struct{ pluginv1.RuntimeServer }
+```
+
+- [ ] **Step 2: Run test to verify it fails**
+
+Run: `go test ./pkg/pluginsdk/runtime/ -run TestGRPCServerRegistersScanSource -v`
+Expected: FAIL — `unknown field 'ScanSource' in struct literal of type CapabilityServers` (the field does not exist yet).
+
+- [ ] **Step 3: Add the struct field**
+
+In `pkg/pluginsdk/runtime/runtime.go`, add to the `CapabilityServers` struct (after the `ScheduledTask` field):
+
+```go
+	ScheduledTask    pluginv1.ScheduledTaskServer
+	ScanSource       pluginv1.ScanSourceServer
+```
+
+- [ ] **Step 4: Add the `Client` accessor**
+
+After the existing `func (c *Client) ScheduledTask() ...` method, add:
+
+```go
+func (c *Client) ScanSource() pluginv1.ScanSourceClient {
+	return pluginv1.NewScanSourceClient(c.conn)
+}
+```
+
+- [ ] **Step 5: Add the conditional registration in `GRPCServer`**
+
+In `func (p *GRPCPlugin) GRPCServer(...)`, after the `ScheduledTask` registration block, add:
+
+```go
+	if p.Servers.ScheduledTask != nil {
+		pluginv1.RegisterScheduledTaskServer(server, p.Servers.ScheduledTask)
+	}
+	if p.Servers.ScanSource != nil {
+		pluginv1.RegisterScanSourceServer(server, p.Servers.ScanSource)
+	}
+```
+
+- [ ] **Step 6: Run test to verify it passes**
+
+Run: `go test ./pkg/pluginsdk/runtime/ -run TestGRPCServerRegistersScanSource -v`
+Expected: PASS.
+
+- [ ] **Step 7: Commit**
+
+```bash
+git add pkg/pluginsdk/runtime/runtime.go pkg/pluginsdk/runtime/runtime_test.go
+git commit -m "feat(runtime): serve and dial scan_source.v1 capability"
+```
+
+---
+
+## Task 4: Prove a `scan_source.v1` manifest loads
+
+Guards the end-to-end path: a plugin manifest declaring the new capability must pass the loader (it would not before Task 2's allowlist entry).
+
+**Files:**
+- Modify: `pkg/pluginsdk/manifest/manifest_test.go`
+
+- [ ] **Step 1: Write the failing test**
+
+The test file is package `manifest_test` (external) and loads from a JSON literal via `manifest.Load([]byte)`. Append this test, mirroring `TestLoadAcceptsRequestRouterCapability` exactly with the type swapped to `scan_source.v1`:
+
+```go
+func TestLoadAcceptsScanSourceCapability(t *testing.T) {
+	raw := []byte(`{
+	  "plugin_id": "silo.example",
+	  "version": "1.0.0",
+	  "silo_api_version": "v1",
+	  "capabilities": [
+	    {"type": "scan_source.v1", "id": "arr", "display_name": "X", "description": "Y"}
+	  ]
+	}`)
+	m, err := manifest.Load(raw)
+	if err != nil {
+		t.Fatalf("Load returned unexpected error: %v", err)
+	}
+	if len(m.GetCapabilities()) != 1 {
+		t.Fatalf("expected 1 capability, got %d", len(m.GetCapabilities()))
+	}
+	if got := m.GetCapabilities()[0].GetType(); got != "scan_source.v1" {
+		t.Fatalf("capability type = %q, want scan_source.v1", got)
+	}
+}
+```
+
+- [ ] **Step 2: Run test to verify it fails (before this task's dependency was in place) / passes now**
+
+Run: `go test ./pkg/pluginsdk/manifest/ -run TestLoadAcceptsScanSourceCapability -v`
+Expected: PASS (Task 2 already added `scan_source.v1` to `KnownTypes`). If it FAILS with an unknown-capability-type error, Task 2 was not completed correctly — fix that first.
+
+- [ ] **Step 3: Commit**
+
+```bash
+git add pkg/pluginsdk/manifest/manifest_test.go
+git commit -m "test(manifest): accept scan_source.v1 capability in manifests"
+```
+
+---
+
+## Task 5: Full build + test sweep
+
+**Files:** none (verification only)
+
+- [ ] **Step 1: Build everything**
+
+Run: `go build ./...`
+Expected: exits 0.
+
+- [ ] **Step 2: Run the full SDK test suite**
+
+Run: `go test ./...`
+Expected: all packages `ok`. Confirms the additive change broke no existing capability, manifest, or runtime test.
+
+- [ ] **Step 3: Vet + format**
+
+Run: `go vet ./... && gofmt -l pkg proto 2>/dev/null; test -z "$(gofmt -l pkg)"`
+Expected: vet clean; `gofmt -l pkg` prints nothing.
+
+---
+
+## Task 6: Tag the release
+
+Downstream repos (silo-server host, arr plugin) consume the SDK as a tagged module version.
+
+**Files:** none (release action)
+
+- [ ] **Step 1: Confirm the version to tag**
+
+Check the latest tag: `git tag --list 'v*' | sort -V | tail -3`. The current consumed version is `v0.4.0`; this additive feature warrants a minor bump to **`v0.5.0`** (no breaking changes).
+
+- [ ] **Step 2: Tag and push**
+
+```bash
+git tag v0.5.0
+git push origin v0.5.0
+```
+
+- [ ] **Step 3: Record the contract for downstream plans**
+
+Note in the host and arr-plugin plans that they must require `github.com/Silo-Server/silo-plugin-sdk v0.5.0` and use:
+- `capability.ScanSource` (`"scan_source.v1"`)
+- `runtime.CapabilityServers{ ScanSource: <impl> }` (plugin side)
+- `client.ScanSource()` → `pluginv1.ScanSourceClient.PollChanges(ctx, &pluginv1.PollChangesRequest{CapabilityId, Marker})` (host side)
+- response fields `PollChangesResponse.ChangedPaths []string`, `PollChangesResponse.NextMarker string`
+
+---
+
+## Self-Review notes
+
+- **Spec coverage:** Implements spec §5 (the `scan_source.v1` contract: `PollChanges`, opaque marker, Silo-native paths) and §11 (additive-only; registered in `KnownTypes`; no existing capability modified). Spec §12 build-order step 1 (tag the SDK) is Task 6.
+- **Out of scope here:** the host engine (spec §7), connections (§8), the Autoscan category (§9), and the arr plugin (§10) are separate per-repo plans built against the `v0.5.0` tag produced by Task 6.
+- **Marker is opaque end-to-end:** the proto carries `marker`/`next_marker` as plain strings with no server-side interpretation, satisfying the "any provider's bookmark" requirement.

+# Sonarr/Radarr Scan-Source Plugin Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Build a new installable Silo plugin that implements `scan_source.v1` for Sonarr/Radarr: when the host pulls, it polls arr `/history`, extracts imported + renamed paths, applies its own path rewrites, and returns Silo-native paths + a marker.
+
+**Architecture:** A standalone Go module structured like `silo-plugin-tmdb` — a `manifest.json` declaring `scan_source.v1`, a `main.go` serving `runtime.CapabilityServers{Runtime, ScanSource}` via `runtime.Serve`, and the arr-specific logic ported from the closed silo-server PR #43 (`internal/autoscan/history.go`, `rewrite.go`, `suggest.go`).
+
+**Tech Stack:** Go, `github.com/Silo-Server/silo-plugin-sdk` (`v0.5.0`, the `scan_source.v1` capability), `hashicorp/go-plugin` runtime (via the SDK), arr HTTP API (`X-Api-Key`).
+
+Commands assume the **new plugin repository root** is the cwd (the `silo-plugin-autoscan-arr` checkout, a sibling of this repo like the `silo-plugin-sdk` checkout).
+
+---
+
+## Prerequisites
+
+1. **SDK `v0.5.0`.** Needs `scan_source.v1` from `silo-plugin-sdk` PR #2. Until tagged, depend on the local checkout via replace:
+   ```bash
+   go mod edit -replace github.com/Silo-Server/silo-plugin-sdk=../silo-plugin-sdk
+   ```
+   This points at the `silo-plugin-sdk` checkout (a sibling of this repo). Task 8 finalizes to `v0.5.0`.
+2. **Template:** the `silo-plugin-tmdb` checkout (a sibling of this repo) — copy its `main.go` runtime scaffold, `Makefile`, and `manifest.json` shape.
+3. **Salvage source:** the arr logic is on silo-server `main` at `internal/autoscan/history.go` (imports + renames extraction, bounded window), `rewrite.go` (`applyRewrites`, `normalizeSeparators`), `suggest.go`/`suggest_deps.go` (root-folder suffix-match suggester). Port these verbatim where possible.
+4. **New repo:** create `Silo-Server/silo-plugin-autoscan-arr` (or fork pattern). The plugin is registered in the `silo-plugins` catalog in a separate follow-up (Task 9 notes it).
+

+## File Structure
+
+| File | Responsibility | Action |
+|---|---|---|
+| `go.mod` | module `github.com/Silo-Server/silo-plugin-autoscan-arr`; SDK dep | Create |
+| `manifest.json` | declares `scan_source.v1` capability + `global_config_schema` (path rewrites only; connection arrives per request) | Create |
+| `main.go` | `runtimeServer` (GetManifest/Configure) + `scanSourceServer` (PollChanges); `runtime.Serve` | Create |
+| `internal/arr/history.go` | poll `/history`, imports + renames, bounded window | Create (port) |
+| `internal/arr/rewrite.go` | `applyRewrites`, `normalizeSeparators` | Create (port) |
+| `internal/arr/client.go` | arr HTTP client (`X-Api-Key`, response cap, timeout) | Create |
+| `internal/config/config.go` | parse Configure payload → `{rewrites}` (connection comes per request, not config) | Create |
+| `Makefile` | build (cross-platform), like tmdb | Create |
+
+---
+
+## Task 1: Scaffold the plugin (serves an empty `scan_source.v1`)
+
+**Files:** Create `go.mod`, `manifest.json`, `main.go`, `Makefile`.
+
+- [ ] **Step 1: Module + SDK dep**
+
+```bash
+go mod init github.com/Silo-Server/silo-plugin-autoscan-arr
+go mod edit -replace github.com/Silo-Server/silo-plugin-sdk=../silo-plugin-sdk   # the silo-plugin-sdk checkout, a sibling of this repo
+go get github.com/Silo-Server/silo-plugin-sdk@v0.4.0   # replace points at the scan_source branch checkout
+```
+
+- [ ] **Step 2: manifest.json**
+
+Mirror tmdb's shape, declaring the scan source:
+
+```json
+{
+  "plugin_id": "silo.autoscan.arr",
+  "version": "0.1.0",
+  "checksum": "__CHECKSUM__",
+  "silo_api_version": "v1",
+  "supported_platforms": [
+    {"os": "linux", "arch": "amd64"},
+    {"os": "linux", "arch": "arm64"},
+    {"os": "darwin", "arch": "arm64"}
+  ],
+  "capabilities": [
+    {
+      "type": "scan_source.v1",
+      "id": "arr",
+      "display_name": "Sonarr / Radarr",
+      "description": "Triggers Silo rescans from Sonarr/Radarr import and rename history."
+    }
+  ],
+  "global_config_schema": [
+    {"key": "path_rewrites", "type": "json", "required": false, "display_name": "Path rewrites"}
+  ]
+}
+```
+
+> **Connection is NOT plugin config.** The arr base URL + API key are delivered by the host in each `PollChangesRequest.connection` (resolved from the operator's Autoscan connection — own creds or a reused Requests link). The plugin reads them from the request and stores no credentials. Only path rewrites (and other provider-specific behaviour) live in plugin config.
+
+(Confirm the exact `global_config_schema` entry shape against `silo-plugin-sdk` `pkg/pluginsdk/config` — adapt field names to the SDK's config schema type.)
+
+- [ ] **Step 3: main.go scaffold**
+
+Copy tmdb's `runtimeServer` (GetManifest from embedded manifest; Configure stores config) and add a `scanSourceServer` returning empty for now:
+
+```go
+type scanSourceServer struct{ cfg *config.Config }
+
+func (s *scanSourceServer) PollChanges(ctx context.Context, req *pluginv1.PollChangesRequest) (*pluginv1.PollChangesResponse, error) {
+	return &pluginv1.PollChangesResponse{}, nil
+}
+
+func main() {
+	manifest := mustLoadManifest()
+	rt := &runtimeServer{manifest: manifest}
+	runtime.Serve(runtime.ServeConfig{
+		Servers: runtime.CapabilityServers{
+			Runtime:    rt,
+			ScanSource: &scanSourceServer{cfg: rt.cfg},
+		},
+	})
+}
+```
+
+- [ ] **Step 4: Build**
+
+Run: `go build ./...`
+Expected: exits 0.
+
+- [ ] **Step 5: Commit**
+
+```bash
+git init && git add -A
+git commit -m "feat: scaffold autoscan-arr scan_source.v1 plugin"
+```
+
+---
+
+## Task 2: Config parsing (Configure → path rewrites only)
+
+**Files:** Create `internal/config/config.go`, `internal/config/config_test.go`.
+
+> Connection (base_url/api_key) is NOT config — it arrives per poll in `PollChangesRequest.connection` (Task 5). Plugin config carries only path rewrites.
+
+- [ ] **Step 1: Failing test**
+
+```go
+func TestParseConfig(t *testing.T) {
+	cfg, err := Parse(map[string]string{
+		"path_rewrites": `[{"from":"/mnt/arr/tv","to":"/mnt/media/tv"}]`,
+	})
+	if err != nil { t.Fatalf("Parse: %v", err) }
+	if len(cfg.Rewrites) != 1 || cfg.Rewrites[0].From != "/mnt/arr/tv" { t.Fatalf("bad rewrites: %+v", cfg.Rewrites) }
+}
+```
+
+- [ ] **Step 2: Run → fail.** `go test ./internal/config/` → undefined `Parse`.
+
+- [ ] **Step 3: Implement** `Parse(map[string]string) (*Config, error)` with `Config{Rewrites []Rewrite}` where `Rewrite{From, To string}`; unmarshal `path_rewrites` JSON. Wire `runtimeServer.Configure` to store the parsed config so `scanSourceServer` reads the rewrites.
+
+- [ ] **Step 4: Run → pass.**
+
+- [ ] **Step 5: Commit** `feat(config): parse arr connection and path rewrites`.
+
+---
+
+## Task 3: arr history client (imports + renames, bounded window)
+
+**Files:** Create `internal/arr/client.go`, `internal/arr/history.go`, `internal/arr/history_test.go`.
+
+Port from silo-server `main:internal/autoscan/history.go` (the `ChangedPaths` logic: `downloadFolderImported.importedPath`; `episodeFileRenamed`/`movieFileRenamed` → `path` + `sourcePath`; deletes ignored) and the client (`X-Api-Key`, 1 MiB cap, timeout). The marker is an RFC3339 timestamp; empty marker ⇒ "now".
+
+- [ ] **Step 1: Failing test** — copy the salvaged `history_test.go` (`TestArrHistoryChangedPaths`: imports + both rename paths returned, `grabbed`/`episodeFileDeleted` ignored), renamed to this package, asserting the returned `(paths, nextMarker)`.
+
+- [ ] **Step 2: Run → fail.**
+
+- [ ] **Step 3: Implement** `ChangedPaths(ctx, baseURL, apiKey, since time.Time) (paths []string, newest time.Time, err error)` — port `history.go`, additionally returning the newest history timestamp as the next marker. Apply the bounded window (24h max-lookback floor + overlap buffer) here.
+
+- [ ] **Step 4: Run → pass.**
+
+- [ ] **Step 5: Commit** `feat(arr): poll history for imports and renames`.
+
+---
+
+## Task 4: Path rewrites (→ Silo-native paths)
+
+**Files:** Create `internal/arr/rewrite.go`, `internal/arr/rewrite_test.go`.
+
+Port `applyRewrites` (boundary-safe prefix: `path==trimmed || HasPrefix(path, trimmed+"/")`) and `normalizeSeparators` from silo-server `main:internal/autoscan/rewrite.go`.
+
+- [ ] **Step 1: Failing test** — copy salvaged `rewrite_test.go` cases.
+- [ ] **Step 2: Run → fail.**
+- [ ] **Step 3: Implement** the port.
+- [ ] **Step 4: Run → pass.**
+- [ ] **Step 5: Commit** `feat(arr): boundary-safe path rewrites`.
+
+---
+
+## Task 5: Wire `PollChanges` end-to-end
+
+**Files:** Modify `main.go` (`scanSourceServer.PollChanges`), add `main_test.go`.
+
+- [ ] **Step 1: Failing test** — a `scanSourceServer` (rewrites configured) called with a `PollChangesRequest` whose `Connection` points at a stub arr server (httptest); assert `PollChanges` with empty marker returns rewritten Silo-native paths and a non-empty `next_marker`, and that the request actually hit the stub at `connection.base_url` with `X-Api-Key: connection.api_key`. A second call with the returned marker queries arr with the right `since`. Also assert a request with a nil/empty `Connection` returns an error (no credentials to poll with).
+
+- [ ] **Step 2: Run → fail.**
+
+- [ ] **Step 3: Implement** — read the connection from the request, not from config:
+
+```go
+func (s *scanSourceServer) PollChanges(ctx context.Context, req *pluginv1.PollChangesRequest) (*pluginv1.PollChangesResponse, error) {
+	conn := req.GetConnection()
+	if conn == nil || conn.GetBaseUrl() == "" {
+		return nil, fmt.Errorf("scan_source: no connection supplied")
+	}
+	since := time.Time{} // empty marker => now (history client floors to now)
+	if m := req.GetMarker(); m != "" {
+		if t, err := time.Parse(time.RFC3339, m); err == nil { since = t }
+	}
+	raw, newest, err := arr.ChangedPaths(ctx, conn.GetBaseUrl(), conn.GetApiKey(), since)
+	if err != nil { return nil, err }
+	out := make([]string, 0, len(raw))
+	for _, p := range raw {
+		out = append(out, arr.ApplyRewrites(arr.NormalizeSeparators(p), s.cfg.Rewrites))
+	}
+	return &pluginv1.PollChangesResponse{ChangedPaths: out, NextMarker: newest.UTC().Format(time.RFC3339)}, nil
+}
+```
+
+- [ ] **Step 4: Run → pass.**
+
+- [ ] **Step 5: Commit** `feat: PollChanges returns Silo-native paths from arr history`.
+
+---
+
+## Task 6: Rewrite suggester ("Sync from arr") — root folders
+
+**Files:** Create `internal/arr/suggest.go`, `suggest_test.go`.
+
+Port `suggestRewrites` (suffix-match arr root folders → Silo folders) from `main:internal/autoscan/suggest.go`. **Open question (spec §14 risk #2):** how the operator triggers "Sync" and how the plugin reaches Silo's media-folder list.
+
+- [ ] **Step 1:** Decide the delivery mechanism — recommended: the plugin reads Silo's folder list via the host library-listing service (`pluginhost` library lister, reachable through the SDK `runtime.Host()` client). Confirm that path exists in `v0.5.0`; if not, scope "Sync" to a follow-up and ship Tasks 1–5 (manual rewrites only) first.
+- [ ] **Step 2:** Port the suffix-match suggester + its tests (unique/ambiguous/covered/no-op/normalization cases from `suggest_test.go`).
+- [ ] **Step 3:** Expose it — either via an `http_routes.v1` capability the admin UI calls, or as part of the plugin config flow. Document the chosen mechanism.
+- [ ] **Step 4:** Tests pass; commit `feat(arr): suffix-match rewrite suggester`.
+
+> If §14 risk #2 is unresolved at execution time, **skip this task**, ship manual rewrites (Tasks 1–5), and file the suggester as a follow-up. The plugin is fully functional without it.
+
+---
+
+## Task 7: Cross-repo smoke test against the host
+
+**Files:** none (verification).
+
+- [ ] **Step 1:** Build the plugin binary; install it into a dev silo-server (with the Part-1 backend) via the plugin installer.
+- [ ] **Step 2:** Configure a source pointing at a real/stub arr; trigger an autoscan poll; confirm the host enqueues a scan for an imported path. (This exercises the full SDK contract end-to-end.)
+- [ ] **Step 3:** Note results; no commit unless fixes are needed.
+
+---
+
+## Task 8: Finalize SDK dependency
+
+- [ ] After `silo-plugin-sdk v0.5.0` is tagged: `go mod edit -dropreplace ...; go get .../silo-plugin-sdk@v0.5.0; go mod tidy; go build ./...`.
+- [ ] Commit `build: depend on silo-plugin-sdk v0.5.0`.
+- [ ] Do not publish/tag the plugin with a `replace` directive in `go.mod`.
+
+---
+
+## Task 9: Catalog registration (follow-up, separate repo)
+
+- [ ] Add `silo.autoscan.arr` to the `silo-plugins` catalog manifest so it is installable. This is a separate PR in the `silo-plugins` repo (not this module) — note it; out of scope for this plan's repo.
+
+---
+
+## Self-Review notes
+
+- **Spec coverage:** §10 (arr plugin: history imports + renames, bounded window, rewrites, Silo-native paths) Tasks 3–5; §5 contract (`PollChanges`, opaque marker = RFC3339 timestamp, first-run "now") Task 5; "Sync from arr" §10/§14-risk-2 Task 6 (with an explicit skip path).
+- **Salvage:** history/rewrite/suggest ported from the closed PR (Tasks 3,4,6) — exactly the files the host backend plan deletes (Part-1 Task 8).
+- **Risk:** §14 risk #1 (one plugin installation per arr server vs. many) — this plugin holds one connection per installation/config; multiple arr servers ⇒ multiple installs unless the runtime supports multiple capability instances. §14 risk #2 (Sync UI) gated in Task 6 with a clean skip.
+- **Type consistency:** `Config{Rewrites}` (no creds — connection arrives in `PollChangesRequest.connection`), `Rewrite{From,To}`, `arr.ChangedPaths(ctx, baseURL, apiKey, since) ([]string, time.Time, error)`, `arr.ApplyRewrites`/`NormalizeSeparators`, `scanSourceServer.PollChanges` consistent across Tasks 2–6.

+# Autoscan Admin UI Implementation Plan (Part 2 of 2)
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Give Autoscan its own admin category (page + sidebar nav), separate from Requests: manage Connections (reuse a Requests arr server or enter own), Sources (per scan-source plugin: enable, interval, connection), and global settings — backed by the Part-1 v2 API.
+
+**Architecture:** Extract the Autoscan tab out of `AdminRequests.tsx` into a standalone `AdminAutoscan.tsx` page; register a route and a sidebar item; rebuild `useAutoscan.ts` hooks + `types.ts` against the v2 endpoints (`/admin/autoscan/{settings,connections,sources,trigger,status}`).
+
+**Tech Stack:** React + TypeScript, React Query (`@tanstack/react-query`), the project's `ui/` component library (`Tabs`, `Table`, `Card`, etc.), `react-router` routes in `App.tsx`, 2-space indent / double quotes / 100-col (`web/.prettierrc`).
+
+Commands assume the silo-server repository root is the cwd. **Depends on Part 1 (backend)** being implemented (the v2 endpoints must exist).
+
+---
+
+## Prerequisites
+
+1. **Part-1 backend merged/available** — the v2 endpoints and response shapes (connections with `request_integration_id`, sources with `marker`/`last_error`, settings with `default_poll_interval_seconds`).
+2. **Reference the existing autoscan tab** at `web/src/pages/AdminRequests.tsx` (the `autoscan` `TabsContent`, the `AutoscanTab`/`AutoscanSourceEditor` components) and hooks at `web/src/hooks/queries/useAutoscan.ts` — these are the starting material; they are reshaped, not discarded.
+3. **Run before MR:** `cd web && pnpm run lint && pnpm run format:check`. Note the 20 pre-existing failing frontend tests are unrelated (project memory); do not be alarmed if they appear — only newly-introduced failures matter.

+## Task 1: v2 types + hooks
+
+**Files:** Modify `web/src/api/types.ts`, `web/src/hooks/queries/keys.ts`; rewrite `web/src/hooks/queries/useAutoscan.ts`.
+
+- [ ] **Step 1: Types**
+
+Add to `web/src/api/types.ts`:
+
+```ts
+export interface AutoscanSettings {
+  enabled: boolean;
+  default_poll_interval_seconds: number;
+  debounce_seconds: number;
+}
+
+export interface AutoscanConnection {
+  id: string;
+  name: string;
+  kind: string;
+  // present when the connection has its own credentials:
+  base_url?: string;
+  // present when linked to a Requests integration (live reuse):
+  request_integration_id?: string | null;
+  // NOTE: api_key_ref / resolved keys are never sent by the backend.
+}
+
+export interface AutoscanSource {
+  id: string;
+  installation_id: number;
+  capability_id: string;
+  connection_id: string;
+  enabled: boolean;
+  poll_interval_seconds: number | null;
+  last_run_at: string | null;
+  last_error: string | null;
+}
+```
+
+- [ ] **Step 2: Hooks**
+
+Rewrite `useAutoscan.ts` with: `useAutoscanSettings`/`useUpdateAutoscanSettings`, `useAutoscanConnections`/`useCreateAutoscanConnection`/`useUpdateAutoscanConnection`/`useDeleteAutoscanConnection`, `useAutoscanSources`/`useUpdateAutoscanSource`, `useAutoscanStatus`, `useTriggerAutoscan`. Follow the existing hook style (the current `useAutoscan.ts` is the template for query/mutation + invalidation). Add query keys in `keys.ts`.
+
+- [ ] **Step 3: Typecheck**
+
+Run: `cd web && pnpm exec tsc --noEmit`
+Expected: no type errors in the autoscan files.
+
+- [ ] **Step 4: Commit**
+
+```bash
+git add web/src/api/types.ts web/src/hooks/queries/useAutoscan.ts web/src/hooks/queries/keys.ts
+git commit -m "feat(web): autoscan v2 types and query hooks"
+```
+
+---
+
+## Task 2: Connections panel
+
+**Files:** Create `web/src/pages/admin/autoscan/ConnectionsPanel.tsx`.
+
+- [ ] **Step 1: Build the panel**
+
+A `Card` + `Table` listing connections (name, kind, and a "Reused from Requests" / "Own" badge derived from `request_integration_id`). An "Add connection" dialog offers two modes:
+- **Reuse from Requests** — a select populated from the existing request-integrations hook (filter to arr kinds), storing `request_integration_id`.
+- **Enter own** — name + URL + API key fields, posting own credentials.
+
+Edit + delete actions per row. Never render any key material (the backend doesn't send it).
+
+- [ ] **Step 2: Lint/format/typecheck**
+
+Run: `cd web && pnpm run lint && pnpm exec tsc --noEmit`
+Expected: clean.
+
+- [ ] **Step 3: Commit** `feat(web): autoscan connections panel (reuse or own)`.
+
+---
+
+## Task 3: Sources panel
+
+**Files:** Create `web/src/pages/admin/autoscan/SourcesPanel.tsx`.
+
+- [ ] **Step 1: Build the panel**
+
+A `Table` of sources, one row per installed `scan_source` capability instance: plugin/capability label, a connection `<select>` (bound to `connection_id`), an enable toggle, a poll-interval input (blank = settings default), and a status column (`last_run_at`, `last_error`). Reuse the spinner/"Syncing…" affordances from the old `AutoscanSourceEditor` where relevant. Wire to `useAutoscanSources`/`useUpdateAutoscanSource`.
+
+- [ ] **Step 2: Lint/format/typecheck** — clean.
+- [ ] **Step 3: Commit** `feat(web): autoscan sources panel`.
+
+---
+
+## Task 4: The Autoscan page + global settings + manual trigger
+
+**Files:** Create `web/src/pages/AdminAutoscan.tsx`.
+
+- [ ] **Step 1: Compose the page**
+
+A page with a `Tabs` (or sections): **Sources**, **Connections**, **Settings**. Settings = global enable toggle, default poll interval, debounce. A "Run now" button calling `useTriggerAutoscan` (202 → toast "Autoscan triggered"). Mirror the header/layout of `AdminRequests.tsx` for visual consistency.
+
+- [ ] **Step 2: Lint/format/typecheck** — clean.
+- [ ] **Step 3: Commit** `feat(web): standalone Autoscan admin page`.
+
+---
+
+## Task 5: Route + sidebar nav
+
+**Files:** Modify `web/src/App.tsx`, `web/src/components/AdminSidebar.tsx`.
+
+- [ ] **Step 1: Route**
+
+In `web/src/App.tsx`, next to `<Route path="requests" element={<AdminRequests />} />` (l.374), add:
+
+```tsx
+<Route path="autoscan" element={<AdminAutoscan />} />
+```
+
+with the matching `import AdminAutoscan from "@/pages/AdminAutoscan";`.
+
+- [ ] **Step 2: Sidebar item**
+
+In `web/src/components/AdminSidebar.tsx`, under the **Content** group (after the Requests item, ~l.112), add:
+
+```tsx
+{
+  label: "Autoscan",
+  icon: <RefreshCw className="h-[18px] w-[18px]" />,
+  href: "/admin/autoscan",
+},
+```
+
+(Import an appropriate icon from the icon set already used in the file.)
+
+- [ ] **Step 3: Verify navigation**
+
+Run: `cd web && pnpm run build`
+Expected: build succeeds. Manually confirm `/admin/autoscan` renders and the sidebar item highlights.
+
+- [ ] **Step 4: Commit** `feat(web): route and sidebar nav for Autoscan category`.
+
+---
+
+## Task 6: Remove the Autoscan tab from Requests
+
+**Files:** Modify `web/src/pages/AdminRequests.tsx`.
+
+- [ ] **Step 1: Excise the tab**
+
+Remove the `<TabsTrigger value="autoscan">` (l.146) and its `<TabsContent value="autoscan">`, the `AutoscanTab`/`AutoscanSourceEditor` definitions (now superseded by the new panels), and `autoscan` from `ADMIN_REQUEST_TABS`. Remove now-unused imports.
+
+- [ ] **Step 2: Lint/format/typecheck/build**
+
+Run: `cd web && pnpm run lint && pnpm run format:check && pnpm run build`
+Expected: clean; build succeeds; no dangling references to removed components.
+
+- [ ] **Step 3: Commit** `refactor(web): move Autoscan out of Requests into its own category`.
+
+---
+
+## Task 7: Final sweep
+
+- [ ] **Step 1:** `cd web && pnpm run lint && pnpm run format:check && pnpm run build` — all clean.
+- [ ] **Step 2:** `cd web && pnpm test` — confirm no **newly** failing tests (the 20 pre-existing failures, per project memory, are unrelated; compare against baseline).
+- [ ] **Step 3:** Manual pass: add a connection (both modes), bind a source, toggle enable, "Run now", confirm status updates.
+
+---
+
+## Self-Review notes
+
+- **Spec coverage:** §9 (Autoscan as its own category, decoupled from Requests; Connections reuse-or-own; per-source enable/interval/status) — Tasks 1–6. The reuse-from-Requests UI (Task 2) surfaces the soft link from spec §8.
+- **Salvage:** the old `AutoscanTab`/`AutoscanSourceEditor` and `useAutoscan.ts` are reshaped (Tasks 1–3), then the Requests tab is removed (Task 6).
+- **Out of scope:** plugin-side config UI (the path-rewrite table lives on the plugin's own settings screen per spec §10 — that is the arr-plugin plan / spec §14 risk #2, not this page).
+- **Type consistency:** `AutoscanConnection{request_integration_id?}`, `AutoscanSource{connection_id,poll_interval_seconds,last_error}`, `AutoscanSettings{default_poll_interval_seconds}` used consistently across hooks (Task 1) and panels (Tasks 2–4).

+# TheIntroDB read-path correctness (Phase 1 / Layer A) — implementation plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Fix the three read-path correctness gaps in the TheIntroDB provider so it matches the
+real v3 API contract: (1) honor **TVDB** ids in lookups (today they are silently dropped),
+(2) capture and use the **real per-segment `confidence`** instead of a hardcoded `0.9`, and
+(3) when the API returns multiple candidate segments, **pick the most-submitted / highest-confidence**
+one instead of the first usable. This is Phase 1 of
+[the marker sources & contribution design](../specs/2026-06-06-marker-sources-and-contribution-design.md);
+it stands alone, ships value immediately (anime / TheTVDB-first libraries start getting markers),
+and unblocks the "query-all / best-wins" merge in later phases.
+
+**Architecture:** All changes are contained within `internal/markers/introdb` plus one added
+field on `markers.Marker`. The resolver already populates the TVDB id into
+`Request.ExternalIDs` — only the provider and HTTP client drop it. The HTTP `Client` gains a
+`tvdbID` argument on `FetchEpisode`/`FetchMovie` (query preference `tmdb → tvdb → imdb`, cache
+keys extended); the provider reads `ExternalIDKeyTVDB`; `segmentTimestamps` gains `confidence`
+and `submission_count`; `pickMarker` uses real confidence (with a named default) and ranks
+candidates. The write path (`BuildUpdatePayload` / `UpsertMarkers`) is **not** touched here.
+
+**Out of scope (deferred to Phase 2):** threading *per-segment* confidence through
+`MarkerUpdatePayload` and `UpsertMarkers`. That refactor only becomes observable once
+`Registry.FetchMerged` can combine segments from different providers; with a single provider
+today the existing "max confidence across segments" collapse is equivalent, and changing it now
+would break `TestBuildUpdatePayloadAggregatesConfidence` for no functional gain. It lands with
+the merge dispatch in Phase 2.
+
+**Tech Stack:** Go (the `internal/markers/introdb` package is pure Go — no libvips/CGO),
+PostgreSQL is not involved (no migration), no frontend changes. Tests run in a throwaway Go
+container (the host has no Go toolchain); a named volume caches module downloads.
+
+Commands assume the repository root is the cwd.
+
+---
+
+## Running tests (host has no Go toolchain)
+
+`internal/markers` and `internal/markers/introdb` are pure Go, so no libvips is needed:
+
+```bash
+docker run --rm -v "$PWD":/app -w /app -v silo-gomod:/go/pkg/mod \
+  -e GOFLAGS=-mod=mod golang:1.26 \
+  go test ./internal/markers/... -v
+```
+
+To run a single test, append `-run TestName` and narrow the package path, e.g.
+`go test ./internal/markers/introdb/ -run TestFetchEpisodeSendsTVDBWhenNoTMDB -v`.
+
+---
+
+## File structure
+
+- `internal/markers/introdb/types.go` — **modify**. Add `Confidence` + `SubmissionCount` to `segmentTimestamps`; add the `defaultConfidence` const.
+- `internal/markers/types.go` — **modify**. Add `SubmissionCount` to `markers.Marker`.
+- `internal/markers/introdb/client.go` — **modify**. `tvdbID` arg on `FetchEpisode`/`FetchMovie`; query preference `tmdb → tvdb → imdb`; cache keys include tvdb.
+- `internal/markers/introdb/provider.go` — **modify**. Read `ExternalIDKeyTVDB` and pass it through; rewrite `pickMarker` for real confidence + best-candidate.
+- `internal/markers/introdb/client_test.go` — **create**. httptest-based client tests (TVDB query, TMDB preference, caching).
+- `internal/markers/introdb/provider_test.go` — **create**. End-to-end provider tests (TVDB-only resolves, real/default confidence, best-candidate).
+
+No migration, no wiring change (`cmd/silo/main.go` constructs the provider but never calls the
+client directly), no frontend change.
+
+---
+
+## Task 1: Type plumbing — capture confidence + submission_count
+
+**Files:**
+- Modify: `internal/markers/introdb/types.go`
+- Modify: `internal/markers/types.go`
+
+This task is pure struct plumbing (no behavior yet); later tasks' tests exercise it. Verify by
+compilation.
+
+- [ ] **Step 1: Add the response fields + default constant in `introdb/types.go`**
+
+Replace the `Algorithm` const block to add `defaultConfidence` after it:
+
+```go
+// Algorithm is the algorithm tag written alongside markers. The version
+// suffix lets us invalidate or refresh markers if the upstream contract
+// changes.
+const Algorithm = "introdb:v3"
+
+// defaultConfidence is applied when TheIntroDB omits a per-segment confidence
+// in the /media response. Real per-segment confidence is preferred when present.
+const defaultConfidence = 0.9
+```
+
+Replace the `segmentTimestamps` struct with the version that decodes the two extra fields the
+v3 `/media` response carries:
+
+```go
+// segmentTimestamps is the per-occurrence shape returned by TheIntroDB.
+// Either bound may be nil — for intro/recap, start may be omitted (segment
+// begins at file start); for credits/preview, end may be omitted (segment
+// runs to file end). Confidence and SubmissionCount are optional per-segment
+// quality signals used to pick among multiple candidates.
+type segmentTimestamps struct {
+	StartMs         *int64   `json:"start_ms,omitempty"`
+	EndMs           *int64   `json:"end_ms,omitempty"`
+	Confidence      *float64 `json:"confidence,omitempty"`
+	SubmissionCount *int     `json:"submission_count,omitempty"`
+}
+```
+
+- [ ] **Step 2: Add `SubmissionCount` to `markers.Marker`**
+
+In `internal/markers/types.go`, replace the `Marker` struct:
+
+```go
+type Marker struct {
+	Kind            MarkerKind
+	Start           time.Duration
+	End             time.Duration
+	Confidence      float64
+	SubmissionCount int
+}
+```
+
+- [ ] **Step 3: Verify the packages still compile**
+
+```bash
+docker run --rm -v "$PWD":/app -w /app -v silo-gomod:/go/pkg/mod \
+  -e GOFLAGS=-mod=mod golang:1.26 \
+  go build ./internal/markers/...
+```
+
+Expected: no output, exit 0. (Existing `write_test.go` / `types_test.go` use field-keyed
+literals, so the added field does not break them.)
+
+- [ ] **Step 4: Commit**
+
+```bash
+git add internal/markers/introdb/types.go internal/markers/types.go
+git commit -m "feat(markers): decode introdb per-segment confidence + submission_count"
+```
+

+
+**Files:**
+- Modify: `internal/markers/introdb/client.go`
+- Modify: `internal/markers/introdb/provider.go`
+- Create: `internal/markers/introdb/client_test.go`
+
+- [ ] **Step 1: Write the failing client tests**
+
+Create `internal/markers/introdb/client_test.go`:

+
+- [ ] **Step 2: Run the tests to verify they fail**
+
+```bash
+docker run --rm -v "$PWD":/app -w /app -v silo-gomod:/go/pkg/mod \
+  -e GOFLAGS=-mod=mod golang:1.26 \
+  go test ./internal/markers/introdb/ -run 'TestFetch' -v
+```
+
+Expected: FAIL — compile error (`FetchEpisode`/`FetchMovie` still take the old 6/4-arg
+signatures without `tvdbID`).
+
+- [ ] **Step 3: Add `tvdbID` to `FetchEpisode` in `client.go`**
+
+Replace the whole `FetchEpisode` method:
+
+```go
+// FetchEpisode looks up segment timestamps for a TV episode.
+// At least one of tmdbID, tvdbID, or imdbID must be non-empty.
+func (c *Client) FetchEpisode(ctx context.Context, tmdbID, tvdbID, imdbID string, season, episode int, durationMS int64) (*mediaResponse, error) {
+	if tmdbID == "" && tvdbID == "" && imdbID == "" {
+		return nil, fmt.Errorf("introdb: tmdb_id, tvdb_id, or imdb_id required")
+	}
+	if season <= 0 || episode <= 0 {
+		return nil, fmt.Errorf("introdb: episode lookup requires season and episode > 0 (got %d/%d)", season, episode)
+	}
+	q := url.Values{}
+	switch {
+	case tmdbID != "":
+		q.Set("tmdb_id", tmdbID)
+	case tvdbID != "":
+		q.Set("tvdb_id", tvdbID)
+	default:
+		q.Set("imdb_id", imdbID)
+	}
+	q.Set("season", strconv.Itoa(season))
+	q.Set("episode", strconv.Itoa(episode))
+	if durationMS > 0 {
+		q.Set("duration_ms", strconv.FormatInt(durationMS, 10))
+	}
+	return c.fetch(ctx, q, cacheKeyEpisode(tmdbID, tvdbID, imdbID, season, episode, durationMS))
+}
+```
+
+- [ ] **Step 4: Add `tvdbID` to `FetchMovie` in `client.go`**
+
+Replace the whole `FetchMovie` method:
+
+```go
+// FetchMovie looks up segment timestamps for a movie.
+// At least one of tmdbID, tvdbID, or imdbID must be non-empty.
+func (c *Client) FetchMovie(ctx context.Context, tmdbID, tvdbID, imdbID string, durationMS int64) (*mediaResponse, error) {
+	if tmdbID == "" && tvdbID == "" && imdbID == "" {
+		return nil, fmt.Errorf("introdb: tmdb_id, tvdb_id, or imdb_id required")
+	}
+	q := url.Values{}
+	switch {
+	case tmdbID != "":
+		q.Set("tmdb_id", tmdbID)
+	case tvdbID != "":
+		q.Set("tvdb_id", tvdbID)
+	default:
+		q.Set("imdb_id", imdbID)
+	}
+	if durationMS > 0 {
+		q.Set("duration_ms", strconv.FormatInt(durationMS, 10))
+	}
+	return c.fetch(ctx, q, cacheKeyMovie(tmdbID, tvdbID, imdbID, durationMS))
+}
+```
+
+- [ ] **Step 5: Extend the cache-key helpers in `client.go`**
+
+Replace both `cacheKeyEpisode` and `cacheKeyMovie`:
+
+```go
+func cacheKeyEpisode(tmdbID, tvdbID, imdbID string, season, episode int, durationMS int64) string {
+	switch {
+	case tmdbID != "":
+		return fmt.Sprintf("tmdb:%s:s%de%d:d%d", tmdbID, season, episode, durationMS)
+	case tvdbID != "":
+		return fmt.Sprintf("tvdb:%s:s%de%d:d%d", tvdbID, season, episode, durationMS)
+	default:
+		return fmt.Sprintf("imdb:%s:s%de%d:d%d", imdbID, season, episode, durationMS)
+	}
+}
+
+func cacheKeyMovie(tmdbID, tvdbID, imdbID string, durationMS int64) string {
+	switch {
+	case tmdbID != "":
+		return fmt.Sprintf("tmdb:movie:%s:d%d", tmdbID, durationMS)
+	case tvdbID != "":
+		return fmt.Sprintf("tvdb:movie:%s:d%d", tvdbID, durationMS)
+	default:
+		return fmt.Sprintf("imdb:movie:%s:d%d", imdbID, durationMS)
+	}
+}
+```
+
+- [ ] **Step 6: Read TVDB in the provider and pass it through (`provider.go`)**
+
+Replace the id-extraction block in `FetchMarkers` (the `tmdbID`/`imdbID` lines and the empty
+guard):
+
+```go
+	tmdbID := strings.TrimSpace(req.ExternalIDs[markers.ExternalIDKeyTMDB])
+	tvdbID := strings.TrimSpace(req.ExternalIDs[markers.ExternalIDKeyTVDB])
+	imdbID := strings.TrimSpace(req.ExternalIDs[markers.ExternalIDKeyIMDB])
+	if tmdbID == "" && tvdbID == "" && imdbID == "" {
+		return markers.Result{}, nil
+	}
+```
+
+Then update the two client calls in the `switch req.Kind` block to pass `tvdbID`:
+
+```go
+		resp, err = p.client.FetchEpisode(ctx, tmdbID, tvdbID, imdbID, req.SeasonNumber, req.EpisodeNumber, durationMS)
+```
+```go
+		resp, err = p.client.FetchMovie(ctx, tmdbID, tvdbID, imdbID, durationMS)
+```
+
+- [ ] **Step 7: Run the client tests to verify they pass**
+
+```bash
+docker run --rm -v "$PWD":/app -w /app -v silo-gomod:/go/pkg/mod \
+  -e GOFLAGS=-mod=mod golang:1.26 \
+  go test ./internal/markers/introdb/ -run 'TestFetch' -v
+```
+
+Expected: PASS (all four `TestFetch*` tests).
+
+- [ ] **Step 8: Commit**
+
+```bash
+git add internal/markers/introdb/client.go internal/markers/introdb/provider.go internal/markers/introdb/client_test.go
+git commit -m "fix(markers): honor TVDB ids in TheIntroDB lookups"

+- [ ] **Step 2: Run the tests to verify they fail**
+
+```bash
+docker run --rm -v "$PWD":/app -w /app -v silo-gomod:/go/pkg/mod \
+  -e GOFLAGS=-mod=mod golang:1.26 \
+  go test ./internal/markers/introdb/ -run TestProvider -v
+```
+
+Expected: FAIL — `TestProviderUsesRealConfidence` sees `0.9` (hardcoded), `TestProviderPicksMostSubmittedCandidate`
+gets the first usable (`end=50s`, `SubmissionCount=0`). (`TestProviderResolvesTVDBOnly` already
+passes from Task 2 — it guards against regression.)
+
+- [ ] **Step 3: Rewrite `pickMarker` in `provider.go`**
+
+Replace the entire `pickMarker` function:
+
+```go
+// pickMarker selects the best usable segment from a TheIntroDB response array.
+// `requireEnd` is true for segments where the end timestamp is the load-bearing
+// field (intro, recap) — they're allowed to start at 0 if `start_ms` is omitted.
+// For trailing segments (credits, preview) the start is required but the end
+// defaults to the file duration. When several candidates are usable (e.g. no
+// duration match narrowed the set), the most-submitted one wins, with higher
+// confidence breaking ties; with a single candidate this is the previous
+// first-usable behavior. Real per-segment confidence is used when present,
+// falling back to defaultConfidence only when the API omits it.
+func pickMarker(stamps []segmentTimestamps, kind markers.MarkerKind, totalDuration time.Duration, requireEnd bool) (markers.Marker, bool) {
+	best := markers.Marker{}
+	bestSubs := -1
+	found := false
+	for _, s := range stamps {
+		start := time.Duration(0)
+		end := totalDuration
+		if s.StartMs != nil {
+			start = time.Duration(*s.StartMs) * time.Millisecond
+		}
+		if s.EndMs != nil {
+			end = time.Duration(*s.EndMs) * time.Millisecond
+		}
+		if requireEnd && s.EndMs == nil {
+			continue
+		}
+		if !requireEnd && s.StartMs == nil {
+			continue
+		}
+		if end <= start {
+			continue
+		}
+		confidence := defaultConfidence
+		if s.Confidence != nil {
+			confidence = *s.Confidence
+		}
+		subs := 0
+		if s.SubmissionCount != nil {
+			subs = *s.SubmissionCount
+		}
+		if !found || subs > bestSubs || (subs == bestSubs && confidence > best.Confidence) {
+			best = markers.Marker{Kind: kind, Start: start, End: end, Confidence: confidence, SubmissionCount: subs}
+			bestSubs = subs
+			found = true
+		}
+	}
+	return best, found
+}
+```
+
+- [ ] **Step 4: Run the tests to verify they pass**
+
+```bash
+docker run --rm -v "$PWD":/app -w /app -v silo-gomod:/go/pkg/mod \
+  -e GOFLAGS=-mod=mod golang:1.26 \
+  go test ./internal/markers/introdb/ -run TestProvider -v
+```
+
+Expected: PASS (all four `TestProvider*` tests).
+
+- [ ] **Step 5: Commit**
+
+```bash
+git add internal/markers/introdb/provider.go internal/markers/introdb/provider_test.go
+git commit -m "feat(markers): use real introdb confidence and pick best candidate"
+```
+
+---
+
+## Task 4: Full-package regression + integration build
+
+**Files:** none (verification only)
+
+- [ ] **Step 1: Run the entire markers test suite**
+
+```bash
+docker run --rm -v "$PWD":/app -w /app -v silo-gomod:/go/pkg/mod \
+  -e GOFLAGS=-mod=mod golang:1.26 \
+  go test ./internal/markers/... -v
+```
+
+Expected: PASS — the new `introdb` tests plus the existing `write_test.go` /
+`types_test.go` (unchanged behavior: `BuildUpdatePayload` still aggregates max confidence,
+`FetchFirstHit` still uses registration order).
+
+- [ ] **Step 2: Build the binary to confirm nothing downstream broke**
+
+```bash
+docker run --rm -v "$PWD":/app -w /app -v silo-gomod:/go/pkg/mod \
+  -e GOFLAGS=-mod=mod golang:1.26 \
+  go build ./...
+```
+
+Expected: exit 0. (The only callers of the changed client methods are in `provider.go`, updated
+in Task 2; `cmd/silo/main.go` constructs the provider but never calls the client directly.)
+
+- [ ] **Step 3: Confirm the working tree is clean**
+
+```bash
+git status
+```
+
+Expected: clean (all changes committed in Tasks 1–3; this task adds no files).
+
+---
+
+## Self-review notes
+
+- **Gap coverage:** TVDB lookups (Task 2, `TestFetch*` + `TestProviderResolvesTVDBOnly`), real
+  confidence (Task 3, `TestProviderUsesRealConfidence` + `…DefaultsConfidenceWhenAbsent`),
+  best-candidate (Task 3, `TestProviderPicksMostSubmittedCandidate`). Maps to design gaps #1–#3.
+- **Containment:** the client signature change touches exactly one production caller
+  (`provider.go`); `markers.Marker` is constructed only in `provider.go`. Verified by grep before
+  planning, re-verified by the Task 4 `go build ./...`.
+- **No behavior regressions:** the write path is untouched, so `BuildUpdatePayload`'s
+  max-confidence aggregation and its test remain valid; per-segment confidence is deferred to
+  Phase 2 where the merge actually consumes it.
+- **No placeholders:** every code step shows the complete replacement; every run step shows the
+  command and the expected result. No migration, no frontend, no wiring changes.
+- **Default confidence:** `defaultConfidence = 0.9` preserves today's effective value for
+  responses that omit confidence, so existing stored markers keep equivalent provenance.

+# Marker sources & TheIntroDB contribution — implementation plan (all phases)
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking. Implement phases in order; each phase is independently shippable.
+
+**Goal:** Implement the design in
+[2026-06-06-marker-sources-and-contribution-design.md](../specs/2026-06-06-marker-sources-and-contribution-design.md):
+fix the TheIntroDB read-path correctness gaps, formalize a multi-source provider model
+(query-all / best-wins), and add the ability to contribute Silo's own markers back to
+TheIntroDB — configured **per provider, off by default**. Server-side API + data model only;
+web UI is a separate follow-up.
+
+**Architecture:** Five sequential phases. Phase 1 fixes the existing provider (TVDB, real
+confidence, best-candidate). Phase 2 adds a per-provider config table, per-segment marker
+provenance, and `Registry.FetchMerged`. Phase 3 adds the submission client, the contribution
+audit table, and the `ContributionService` engine. Phase 4 exposes the full admin API (manual
+markers, provider config, contribute, history). Phase 5 adds the daily auto-contribution task.
+
+**Tech Stack:** Go (chi handlers, pgx repositories), PostgreSQL (paired numbered migrations),
+no frontend in this plan. Most touched packages (`internal/markers`, `internal/markers/introdb`,
+`internal/taskmanager/tasks`) are pure Go; `internal/api/handlers` needs libvips (CGO image
+deps). Tests run in a throwaway Go container (host has no Go toolchain).
+
+Commands assume the repository root is the cwd.
+
+---
+
+## Phase overview & dependencies
+
+| Phase | Delivers | Depends on | New migrations |
+|------|----------|-----------|----------------|
+| 1 | TheIntroDB read-path correctness (TVDB, real confidence, best-candidate) | — | none |
+| 2 | `marker_provider_config` + per-segment provenance + `FetchMerged` | 1 (real confidence) | `marker_provider_config` |
+| 3 | Submission client + `marker_contributions` + `ContributionService` | 2 (`Submitter`, provider config) | `marker_contributions` |
+| 4 | Admin API: manual markers, provider config, contribute, history | 3 (service) | none |
+| 5 | Daily auto-contribution task | 3 (service), 4 (optional) | none |
+
+Phase 1's line-level steps are also captured standalone in
+[2026-06-06-marker-introdb-readpath-correctness.md](2026-06-06-marker-introdb-readpath-correctness.md);
+they are summarized here so this document is self-contained.
+
+---
+
+## Running tests (host has no Go toolchain)
+
+Pure-Go packages (`internal/markers`, `internal/markers/introdb`, `internal/taskmanager/...`):
+
+```bash
+docker run --rm -v "$PWD":/app -w /app -v silo-gomod:/go/pkg/mod \
+  -e GOFLAGS=-mod=mod golang:1.26 \
+  go test ./internal/markers/... -v
+```
+
+`internal/api/handlers` (Phase 4) needs libvips:
+
+```bash
+docker run --rm -v "$PWD":/app -w /app -v silo-gomod:/go/pkg/mod \
+  -e GOFLAGS=-mod=mod golang:1.26 \
+  sh -c 'apt-get update >/dev/null && apt-get install -y --no-install-recommends libvips-dev >/dev/null && go test ./internal/api/handlers/ -run TestAdminMarkers -v'
+```
+
+Whole-project compile: `go build ./...` (same container).
+
+---
+
+## Phase 1 — TheIntroDB read-path correctness
+
+**Goal:** Honor TVDB ids, capture/use real per-segment confidence + submission_count, and pick
+the best candidate among multiple. Contained to `internal/markers/introdb` plus one field on
+`markers.Marker`. No migration, no write-path change.
+
+**Files:** `internal/markers/introdb/{types.go,client.go,provider.go}` (modify),
+`internal/markers/types.go` (modify, add `Marker.SubmissionCount`),
+`internal/markers/introdb/{client_test.go,provider_test.go}` (create).
+
+### Task 1.1 — Type plumbing
+- [ ] Add `Confidence *float64` and `SubmissionCount *int` to `segmentTimestamps`
+  (`introdb/types.go`); add `const defaultConfidence = 0.9`.
+- [ ] Add `SubmissionCount int` to `markers.Marker` (`markers/types.go`).
+- [ ] `go build ./internal/markers/...` → exit 0. Commit.
+
+### Task 1.2 — TVDB lookups (gap #1)
+- [ ] Create `introdb/client_test.go` (httptest): asserts `tvdb_id` sent when only tvdb given,
+  tmdb preferred over tvdb/imdb, movie tvdb, and cache collapses repeat calls. Run → FAIL (compile).
+- [ ] `client.go`: `FetchEpisode`/`FetchMovie` gain a `tvdbID` arg; query preference
+  `tmdb → tvdb → imdb` via a `switch`; the empty-id guard includes tvdb; `cacheKeyEpisode`/
+  `cacheKeyMovie` include a `tvdb:` branch.
+- [ ] `provider.go` `FetchMarkers`: read `req.ExternalIDs[markers.ExternalIDKeyTVDB]`, include it
+  in the empty guard, pass it to both client calls.
+- [ ] Run client tests → PASS. Commit.
+
+### Task 1.3 — Real confidence + best-candidate (gaps #2, #3)
+- [ ] Create `introdb/provider_test.go`: TVDB-only resolves; real confidence used; default when
+  absent; most-submitted candidate wins (ties broken by confidence). Run → FAIL.
+- [ ] Rewrite `pickMarker` to use real confidence (fallback `defaultConfidence`), set
+  `SubmissionCount`, and select the candidate with the highest `(submission_count, confidence)`.
+- [ ] Run → PASS. Commit.
+
+### Task 1.4 — Regression
+- [ ] `go test ./internal/markers/... && go build ./...` → all green (existing `write_test.go`/
+  `types_test.go` unaffected; write path untouched). Commit if needed.
+
+(Full code for every step is in the standalone Phase 1 plan linked above.)
+
+---
+
+# Phase 2 — Per-provider config, per-segment provenance, FetchMerged
+
+**Goal:** Add the `marker_provider_config` table that drives which providers are queried (and,
+later, submitted to); make the marker write path carry **per-segment** provider/confidence/
+algorithm so a merged multi-provider result writes correct provenance; add
+`Registry.FetchMerged` (query all enabled providers, keep the best candidate per segment) and
+switch the lazy-playback path to it. With only TheIntroDB enabled, behavior is unchanged.
+
+**Files:**
+- Create: `migrations/<next>_marker_provider_config.{up,down}.sql`
+- Create: `internal/markers/provider_config.go`, `internal/markers/provider_config_test.go`
+- Modify: `internal/markers/types.go` (`Marker.ProviderID`/`Algorithm`; `Registry.FetchMerged`)
+- Modify: `internal/markers/write.go` (per-segment provenance in `MarkerUpdatePayload`/`BuildUpdatePayload`)
+- Modify: `internal/scanner/file_repo.go` (`MarkerUpdate` + `applySegmentPatch` per-segment provenance)
+- Modify: the `markers.MarkerUpdatePayload` → `scanner.MarkerUpdate` conversion (in the lazy-markers handler/adapter)
+- Modify: `internal/api/handlers/playback_lazy_markers.go` (call `FetchMerged`)
+- Modify: `cmd/silo/main.go` (construct the config store; pass to the registry)
+
+### Task 2.1 — Migration: `marker_provider_config`
+- [ ] Write `migrations/<next>_marker_provider_config.up.sql` (use the next free number; latest is 180):
+
+```sql
+CREATE TABLE public.marker_provider_config (
+    provider                  text PRIMARY KEY,
+    fetch_enabled             boolean NOT NULL DEFAULT true,
+    fetch_priority            integer NOT NULL DEFAULT 100,
+    contribute_enabled        boolean NOT NULL DEFAULT false,
+    contribute_auto_local     boolean NOT NULL DEFAULT false,
+    contribute_min_confidence double precision NOT NULL DEFAULT 0.95,
+    updated_at                timestamptz NOT NULL DEFAULT now()
+);
+INSERT INTO public.marker_provider_config (provider, fetch_enabled) VALUES ('introdb', true);
+```
+
+- [ ] `.down.sql`: `DROP TABLE public.marker_provider_config;`
+- [ ] Commit.
+
+### Task 2.2 — Provider config store
+- [ ] Create `internal/markers/provider_config.go`:
+
+```go
+type ProviderConfig struct {
+    Provider                string
+    FetchEnabled            bool
+    FetchPriority           int
+    ContributeEnabled       bool
+    ContributeAutoLocal     bool
+    ContributeMinConfidence float64
+}
+
+// ProviderConfigStore is a cached read/write façade over marker_provider_config.
+// Reads serve from an in-memory snapshot; Update writes through and refreshes.
+type ProviderConfigStore struct { /* pool, mu, cache map[string]ProviderConfig */ }
+
+func NewProviderConfigStore(pool *pgxpool.Pool) *ProviderConfigStore
+func (s *ProviderConfigStore) Reload(ctx context.Context) error            // load all rows into cache
+func (s *ProviderConfigStore) List() []ProviderConfig                       // snapshot copy
+func (s *ProviderConfigStore) Get(provider string) (ProviderConfig, bool)
+func (s *ProviderConfigStore) Update(ctx context.Context, p ProviderConfig) error // upsert + refresh
+// EnabledForFetch returns fetch_enabled providers sorted by (fetch_priority asc, provider asc).
+func (s *ProviderConfigStore) EnabledForFetch() []ProviderConfig
+```
+
+- [ ] Hot-reload: subscribe the store's `Reload` to the existing `cache.EventSettingsChanged`
+  Redis channel (mirror the `introdb.api_key` reload wiring in `cmd/silo/main.go`), or add a
+  dedicated `marker_provider_config_changed` event published by `Update`. Either is acceptable;
+  document which.
+- [ ] `provider_config_test.go`: with a real/pgxmock pool or an injected fake, assert
+  `EnabledForFetch` filters disabled rows and sorts by priority. Commit.
+
+### Task 2.3 — Per-segment marker provenance (write path)
+
+This makes a merged result (intro from provider A, credits from provider B) persist the correct
+per-segment `*_markers_provider` / `*_markers_confidence` / `*_markers_algorithm`. The DB columns
+already exist; today `applySegmentPatch` applies one shared triple.
+
+- [ ] Add to `markers.Marker`: `ProviderID string`, `Algorithm string` (so each segment carries
+  its origin). `provider.go` (Phase 1) sets these from `ProviderID`/`Algorithm` per marker.
+- [ ] Rework `markers.MarkerUpdatePayload` (`write.go`) from one shared `Confidence`/`Provider`/
+  `Algorithm` to a per-segment struct, e.g.:
+
+```go
+type SegmentPayload struct { Start, End *float64; Provider *string; Confidence *float64; Algorithm string }
+type MarkerUpdatePayload struct {
+    Intro, Credits, Recap, Preview SegmentPayload
+    Source string // shared source class (e.g. "online"); per-kind provider differs
+}
+```
+
+- [ ] Update `BuildUpdatePayload` to fill each `SegmentPayload` from the matching `Marker`
+  (provider/confidence/algorithm per segment). Update `write_test.go`
+  (`TestBuildUpdatePayloadAggregatesConfidence` → assert per-segment confidence: intro 0.7,
+  credits 0.9, recap 0.5).
+- [ ] Read `applySegmentPatch` and the `MarkerUpdatePayload → scanner.MarkerUpdate` conversion
+  first, then extend `scanner.MarkerUpdate` + `applySegmentPatch` so each segment's
+  provider/confidence/algorithm come from that segment (not a shared field). `nextSharedMarkerAttribution`
+  keeps populating the legacy shared `markers_source`/`markers_confidence` columns from the
+  highest-confidence applied segment.
+- [ ] `go test ./internal/markers/... ./internal/scanner/...` → green. Commit.
+
+### Task 2.4 — `Registry.FetchMerged`
+- [ ] Give `Registry` access to the enabled set (constructor takes a `ProviderConfigStore`, or
+  `FetchMerged` takes an `[]ProviderConfig` snapshot). Add:
+
+```go
+// FetchMerged queries every fetch-enabled provider concurrently and keeps, per
+// segment kind, the candidate with the highest (SubmissionCount, Confidence),
+// breaking ties by the provider's fetch_priority. Per-segment ProviderID/
+// Algorithm are preserved so the write path records correct provenance.
+func (r *Registry) FetchMerged(ctx context.Context, req Request) (Result, bool, error)
+```
+
+Algorithm: fan out via goroutines (bounded) to enabled providers; collect `(ProviderConfig,
+Result, error)`; for each `MarkerKind`, choose the best `Marker` across results; assemble a
+`Result` whose `Markers` carry their winning provider's `ProviderID`/`Algorithm`. Log and skip
+provider errors (like `FetchFirstHit`). Return `ok=false` if no segment found.
+
+- [ ] `types_test.go`: add a merge test — two fake providers, one wins intro, the other wins
+  credits by submission_count; assert the merged result has both with correct per-segment
+  ProviderID. Keep the existing `FetchFirstHit` tests. Commit.
+
+### Task 2.5 — Switch lazy path + wire store
+- [ ] In `internal/api/handlers/playback_lazy_markers.go`, replace the `FetchFirstHit` call in
+  `fetchOnlineMarkersForPlayback` with `FetchMerged`.
+- [ ] In `cmd/silo/main.go`, construct `NewProviderConfigStore`, `Reload` it at startup, wire its
+  hot-reload, and pass it to the registry. (TheIntroDB stays registered as today.)
+- [ ] `go build ./... && go test ./internal/markers/...` → green. With only `introdb` enabled,
+  `FetchMerged` returns the same result `FetchFirstHit` did — verify a provider test asserting
+  single-provider parity. Commit.
+
+---
+
+# Phase 3 — Submission client, contribution tracking, service engine
+
+**Goal:** Build the machinery to submit a marker to a provider, idempotently and audited —
+without yet wiring a trigger. Adds the `Submitter` capability, the introdb submission/stats
+client methods, the `marker_contributions` table, and the `ContributionService`.
+
+**Files:**
+- Modify: `internal/markers/types.go` (`Submitter`, `SubmissionRequest`/`SubmissionResult`/`UserStats`)
+- Modify: `internal/markers/introdb/{types.go,client.go,provider.go}` (submit + stats; implement `Submitter`)
+- Create: `migrations/<next>_marker_contributions.{up,down}.sql`
+- Create: `internal/markers/contribution_repo.go`, `internal/markers/contribute.go` (+ tests)
+- Modify: `cmd/silo/main.go` (construct the service)
+
+### Task 3.1 — `Submitter` capability + DTOs
+- [ ] Add to `internal/markers/types.go`:
+
+```go
+type SubmissionRequest struct {
+    Kind          ItemKind
+    ExternalIDs   map[string]string // tmdb/imdb (tvdb not accepted by /submit; tmdb required)
+    SeasonNumber  int
+    EpisodeNumber int
+    Segment       MarkerKind
+    Start, End    *time.Duration // nil start ok for intro/recap; nil end ok for credits/preview
+    Duration      time.Duration
+}
+type SubmissionResult struct { ID string; Status string; Weight float64 } // status: pending|accepted|rejected
+type UserStats struct { Total, Accepted, Pending, Rejected int; AcceptanceRate float64; CurrentStreak, BestStreak int }
+
+type Submitter interface {
+    Provider
+    SubmitMarker(ctx context.Context, req SubmissionRequest) (SubmissionResult, error)
+    FetchUserStats(ctx context.Context) (UserStats, error)
+}
+```
+
+- [ ] Commit (compiles; no implementer yet).
+
+### Task 3.2 — introdb submission client
+- [ ] `introdb/types.go`: add the request/response shapes for `POST /v3/submit`
+  (`tmdb_id`,`imdb_id`,`type`,`segment`,`season`,`episode`,`video_duration_ms`,`start_ms`,`end_ms`;
+  response `{submissions:[{id,status,weight,...}]}`) and `GET /v3/user/stats`. Remove the
+  "Submissions are intentionally not supported" package note.
+- [ ] `introdb/client.go`: add `SubmitSegment(ctx, ...) (*submitResponse, error)` (POST,
+  `Authorization: Bearer` **required** — return an error if `apiKey == ""`; honor
+  `X-UsageLimit-Reset` on 429) and `FetchUserStats(ctx) (*userStats, error)` (GET).
+- [ ] `introdb/provider.go`: implement `markers.Submitter` — map `SubmissionRequest` to the
+  client call (apply the v3 null rules: intro/recap drop a zero start to `null`; credits/preview
+  send `null` end when absent), translate `SubmissionResult`/`UserStats`.
+- [ ] `client_test.go`/`provider_test.go`: httptest asserts the submit body shape, bearer header,
+  and that an empty key errors before any HTTP call; stats parse. Commit.
+
+### Task 3.3 — `marker_contributions` table + repo
+- [ ] Migration `<next>_marker_contributions.up.sql` (per design §C4):
+
+```sql
+CREATE TABLE public.marker_contributions (
+    id                 uuid PRIMARY KEY DEFAULT gen_random_uuid(),
+    media_file_id      integer NOT NULL REFERENCES media_files(id) ON DELETE CASCADE,
+    provider           text    NOT NULL,

+```
+
+- [ ] `.down.sql`: drop the table.
+- [ ] `internal/markers/contribution_repo.go`: `ContributionStore` with `AlreadySubmitted(ctx,
+  fileID, provider, kind, contentHash) (bool, error)`, `Record(ctx, ContributionRow) error`
+  (upsert on the unique key), `ListByFile(ctx, fileID) ([]ContributionRow, error)`. Add a
+  `ContentHash(kind string, startMs, endMs, durationMs *int64) string` helper (stable SHA-256).
+- [ ] Repo test (value-hash idempotency, list). Commit.
+
+### Task 3.4 — `ContributionService`
+- [ ] `internal/markers/contribute.go`:
+
+```go
+type ContributionService struct { /* registry, resolver, cfg *ProviderConfigStore, store *ContributionStore, log */ }
+
+// ContributeFile submits the file's eligible markers to enabled submitter providers.
+// opts may scope to one provider and/or specific segment kinds. Auto callers pass
+// requireAutoLocal=true so only providers with contribute_auto_local participate.
+func (s *ContributionService) ContributeFile(ctx context.Context, file *models.MediaFile, opts ContributeOptions) ([]ContributionOutcome, error)
+```
+
+Per provider (from `cfg.List()` filtered to `Submitter` + `contribute_enabled`, and
+`contribute_auto_local` when `opts.Auto`):
+1. **Eligibility (C2):** for each requested segment present on the file, require
+   `source ∈ {scanner, manual}` (skip `online` — circular); resolve external IDs via the existing
+   resolver (skip if none / tmdb required by `/submit`); for auto require `source=scanner`,
+   `kind=intro`, `confidence ≥ contribute_min_confidence`.
+2. **Idempotency:** compute `ContentHash`; skip if `AlreadySubmitted`.
+3. **Submit:** `provider.(Submitter).SubmitMarker(...)`.
+4. **Persist:** `store.Record(...)` with returned status/submission_id (or `status="error"`).
+
+- [ ] `contribute_test.go` with a fake `Submitter` + in-memory store: asserts online-sourced
+  markers are skipped, sub-threshold auto markers skipped, duplicates skipped, a fresh manual
+  marker submitted and recorded. Commit.
+
+### Task 3.5 — Wire
+- [ ] `cmd/silo/main.go`: construct `ContributionService` (registry, resolver, config store,
+  contribution store). Not yet called by any handler/task. `go build ./...` + tests green. Commit.
+
+---
+
+# Phase 4 — Admin API (manual markers, provider config, contribute, history)
+
+**Goal:** Expose the full backend contract under `RequireAdmin`. Mirror the structure of
+`internal/api/handlers/admin_intro.go` (interface-typed deps, `chi.URLParam`, `writeError`/
+`writeJSON`, `MarkerUpdateNotifier` after writes).
+
+**Files:**
+- Create: `internal/api/handlers/admin_markers.go` (+ test), `internal/api/handlers/admin_marker_providers.go` (+ test)
+- Modify: `internal/api/router.go` (register routes in the `RequireAdmin` group)
+- Modify: `cmd/silo/main.go` (construct + inject the handlers)
+
+### Task 4.1 — Manual marker endpoints (design §C3)
+- [ ] `admin_markers.go`:
+  - `GET /admin/files/{fileId}/markers` → current per-segment values + provenance
+    (`source`,`provider`,`confidence`,`algorithm`,`detected_at`) for intro/recap/credits/preview.
+  - `PUT /admin/files/{fileId}/markers` → body per segment `{start,end}` (seconds) or `null` to
+    clear; write `source = "manual"` via `scanner.FileRepository.UpsertMarkers` (priority 4);
+    then `MarkerUpdateNotifier.MarkersUpdated(file)`. Validation: `end>start`; intro/recap may
+    omit start; credits/preview may omit end; within `[0, duration]`.
+  - `DELETE /admin/files/{fileId}/markers/{segment}` → clear one segment.
+  - `GET|PUT /admin/items/{id}/markers` → resolve to the item's primary file (convenience).
+- [ ] Handler test (libvips container): PUT writes manual markers and returns provenance;
+  invalid range → 400; clear nulls the segment. Commit.
+
+### Task 4.2 — Provider config + validate endpoints (design §C7)
+- [ ] `admin_marker_providers.go`:
+  - `GET /admin/markers/providers` → for each registered provider: id, `isSubmitter`, its
+    `marker_provider_config` row, and (best-effort cached) `UserStats` for submitters with a key.
+  - `PUT /admin/markers/providers/{provider}` → update the config row (validated; unknown → 404).
+  - `POST /admin/markers/providers/{provider}/validate` → `Submitter.FetchUserStats`; non-submitter → 400.
+- [ ] Test: list returns introdb with its config; update flips `contribute_enabled`; validate on
+  a non-submitter → 400. Commit.
+
+### Task 4.3 — Contribution endpoints (design §C7)
+- [ ] In `admin_markers.go` (or a small `admin_contributions.go`):
+  - `POST /admin/files/{fileId}/contribute` (optional body `{provider?, segments?[]}`) →
+    `ContributionService.ContributeFile(...)`; returns per (provider, segment) outcome.
+  - `GET /admin/files/{fileId}/contributions` → `ContributionStore.ListByFile`.
+- [ ] Test with a fake service/store. Commit.
+
+### Task 4.4 — Routing + wiring
+- [ ] Register all new routes inside the existing `RequireAdmin` group in `internal/api/router.go`
+  (mirror the `redetect-intro` registration). Inject the handlers in `cmd/silo/main.go`.
+- [ ] `go build ./... && go test ./internal/api/handlers/ -run 'TestAdminMarkers|TestAdminMarkerProviders'`
+  (libvips container) → green. Commit.
+
+---
+
+# Phase 5 — Daily auto-contribution task
+
+**Goal:** A scheduled task that, for each provider with `contribute_enabled &&
+contribute_auto_local`, submits high-confidence local intro detections that haven't been
+contributed. Mirror `internal/taskmanager/tasks/detect_intro_markers.go`.
+
+**Files:** Create `internal/taskmanager/tasks/contribute_markers.go` (+ test); modify
+`cmd/silo/main.go` (register the task).
+
+### Task 5.1 — `ContributeMarkersTask`
+- [ ] Implement the `taskmanager.Task` interface (`Key="contribute_markers"`, `Name`,
+  `Description`, `Category=TaskCategoryLibrary`, `IsHidden() bool`, `DefaultTriggers()` daily e.g.
+  `"04:00"` — after the 03:30 detection task, `Execute`).
+- [ ] `Execute`: short-circuit if no provider has `contribute_enabled && contribute_auto_local`
+  (read `ProviderConfigStore`). Otherwise page through episode files with
+  `intro_markers_source='scanner'` and `intro_markers_confidence ≥` the provider's
+  `contribute_min_confidence` (a new `ContributionStore`/repo query, batched), and call
+  `ContributionService.ContributeFile(file, ContributeOptions{Auto:true})`. Report progress; obey
+  the introdb usage limit (the client already backs off on `X-UsageLimit-Reset`); idempotency
+  makes interrupted runs resumable.
+- [ ] Test with fakes: enabled+auto submits eligible files; disabled → no-op; sub-threshold
+  skipped. Commit.
+
+### Task 5.2 — Register
+- [ ] Register the task where `DetectIntroMarkersTask` is registered in `cmd/silo/main.go`.
+- [ ] `go build ./... && go test ./internal/taskmanager/...` → green. Commit.
+
+---
+
+## Final integration verification
+
+**Files:** none (build + runtime).
+
+- [ ] **Build the image** (compiles backend + frontend):
+  ```bash
+  docker build --build-arg BUILD_REVISION=$(git rev-parse --short HEAD) --build-arg BUILD_DIRTY=false -t silo-server:markers-test .
+  ```
+- [ ] **Recreate the container** (applies the new migrations on startup) and wait for health:
+  ```bash
+  docker compose up -d silo
+  for i in $(seq 1 24); do s=$(docker inspect -f '{{.State.Health.Status}}' silo-silo-1); echo "$s"; [ "$s" = healthy ] && break; sleep 5; done
+  ```
+- [ ] **Verify migrations applied + tables exist:**
+  ```bash
+  docker compose exec -T postgres psql -U silo -d silo -c \
+    "SELECT to_regclass('public.marker_provider_config'), to_regclass('public.marker_contributions');"
+  docker compose exec -T postgres psql -U silo -d silo -c "SELECT * FROM marker_provider_config;"
+  ```
+  Expected: both tables present; an `introdb` row with `fetch_enabled=t, contribute_enabled=f`.
+- [ ] **Smoke the read path (TVDB):** trigger playback (or call the marker fetch) for a
+  TVDB-only-matched episode and confirm markers now populate where they previously did not.
+- [ ] **Smoke contribution (manual, dry):** enable contribution for introdb against a **test/staging**
+  TheIntroDB key, `PUT` a manual marker on a file, `POST /admin/files/{id}/contribute`, then
+  `GET /admin/files/{id}/contributions` shows a `pending` row; a second contribute is idempotent
+  (no new row). Use a non-production key so test data isn't submitted to the real database.
+- [ ] `git status` → clean (all changes committed per phase).
+
+---
+
+## Self-review notes
+
+- **Phase independence:** each phase compiles, tests, and ships alone; with only `introdb`
+  enabled and contribution off (defaults), Phases 2–5 are observationally inert until an operator
+  enables a provider — so they can land ahead of any behavior change.
+- **Per-provider, off by default:** `contribute_enabled`/`contribute_auto_local` default `false`
+  in the migration; the service refuses to submit otherwise; auto additionally gated on
+  `contribute_auto_local`. The `provider` column on `marker_contributions` and the per-provider
+  loop make multi-target submission first-class.
+- **Circular-contribution guard:** `source='online'` is never contributed (C2 eligibility) — has
+  a dedicated unit test in Task 3.4.
+- **Idempotency:** value `content_hash` + the unique constraint mean repeat/interrupted runs
+  don't double-submit, while a corrected value (new hash) does submit — matching TheIntroDB's
+  weighted-average model.
+- **Write-path accuracy:** Task 2.3 requires reading `applySegmentPatch` and the
+  `MarkerUpdatePayload → scanner.MarkerUpdate` conversion before editing; the per-segment columns
+  already exist in `media_files`, so this is a plumbing change, not a schema change.
+- **Migration numbers:** `marker_provider_config` and `marker_contributions` take the next two
+  free numbers at implementation time (181+; latest on disk is 180). Re-check for collisions
+  before writing.
+- **Out of scope (tracked in the design doc):** all web UI; per-user TheIntroDB accounts; a
+  `marker_provider.v1` plugin capability. Clean seams left for each.

-# Audiobook UI Redesign — Design Spec
-
-**Date:** 2026-05-24
-**Branch context:** `feat/audiobooks` in `silo-server`
-**Status:** Approved — ready for implementation plan
-**Related spec:** [`2026-05-24-audiobooks-absorption-design.md`](./2026-05-24-audiobooks-absorption-design.md)
-
-## Goal
-
-Bring the audiobook detail page and audiobook player to visual and
-interaction parity with Silo's existing video player, translated for
-audio. Today the audiobook surfaces work but feel generic, hide useful
-information, and re-implement primitives the video player already has
-in a polished form.
-
-User-visible outcome:
-
-- The audiobook player has the same two-mode shape as the video player
-  (compact HUD + immersive full-screen mode), so listening can be
-  background or foreground depending on intent.
-- The detail page foregrounds the information audiobook listeners care
-  about — current chapter, narrator, listened progress — instead of
-  burying it.
-- The audiobook-only affordances that don't exist today (sleep timer,
-  speed menu, bookmarks, narrator emphasis) have a home.
-
-## Hard constraints
-
-- **Reuse video-player primitives.** `SeekBar`, `ChaptersMenu`, and the
-  glass-disc button visual treatment all live in `web/src/player/` and
-  are already wired up correctly. The audiobook player must consume
-  them, not re-implement them.
-- **One audio element.** Switching between mini and Now Listening must
-  not remount the audio element or restart the stream. Both modes are
-  chrome layered over the same playback state.
-- **No new top-level routes.** The Now Listening view is an overlay on
-  whatever route the user is on, not a `/audiobooks/listen` page. This
-  mirrors how fullscreen video works — fullscreen is a mode, not a
-  destination.
-- **Player state must be liftable.** The split between
-  `useAudiobookPlayback` (state hook) and `MiniBar` / `NowListening`
-  (chrome) must allow a future v1.1 change to lift the hook into an
-  app-level provider so the mini bar can survive page navigation.
-  v1 itself ships with the player tied to the detail route, same as
-  today.
-
-## Scope
-
-### In
-
-- New mini-bar layout (cover tile, chapter title, glass-disc transport,
-  utility rail with sleep / chapters / speed / expand / close).
-- New Now Listening full-overlay mode (large cover, chapter heading,
-  tall seek bar, sleep / chapters / speed / bookmark / car-mode row,
-  remaining-time toggle, overflow menu).
-- Restructured audiobook detail page (progress + chapter-aware Resume
-  action, chapters expanded by default with currently-playing
-  highlight, narrator card, embedding-based "Similar audiobooks"
-  rail, "Also by author", "In this series").
-- Extraction of `CircleButton` and a new `SpeedMenu` into
-  `web/src/player/components/` as shared primitives between video and
-  audiobook players.
-- Split of today's monolithic `AudiobookPlayer.tsx` into a state hook
-  (`useAudiobookPlayback`) plus two chrome components (`MiniBar`,
-  `NowListening`) under `web/src/pages/audiobooks/player/`.
-- Sleep timer (client-side only; pauses + short fade-out when the
-  timer fires).
-
-### Out (deferred to v1.1)
-
-- **Bookmarks.** UI affordances (mini-bar button, Now Listening
-  utility-row button, "Bookmarks (n)" detail-page action) ship
-  **hidden** in v1. Full feature needs `audiobook_bookmarks` table +
-  CRUD endpoints, which is its own sub-spec.
-- **"Also by narrator" / cross-book "In this series" rails.** Render
-  only when the backend already exposes the data; otherwise hide.
-  Server-side joins to power them are a follow-up.
-- **Car mode.** Hidden in v1; v1.1 will add a huge-buttons layout
-  variant reached from the utility row.
-- **Audiobook library page redesign.** Out of scope; current grid
-  stays.
-- **Persistent player across page navigation as a lifted React
-  context.** The current detail page owns the player state; lifting it
-  to an app-level provider so the bar survives navigating away from
-  the detail page is a follow-up. v1 ships with the bar tied to the
-  detail route, same as today, but visually and structurally ready
-  for that lift.
-
-## Architecture
-
-### Three connected surfaces
-
-```
-detail page  ──opens──►  mini bar  ──expand──►  Now Listening
-                            ▲                       │
-                            └─────── collapse ──────┘
-```
-
-- **Detail page** (`/audiobooks/book/:id`) is the landing surface.
-  Stays mounted while the player is open.
-- **Mini bar** is a fixed bottom strip (current behavior) that appears
-  once the user clicks Play/Resume.
-- **Now Listening** is a full-viewport overlay (z-index above the mini
-  bar, below modals) reached by clicking the cover-art tile or the
-  expand chevron in the mini bar. Dismissed via a collapse chevron.
-
-The mini ↔ Now Listening transition uses a CSS view transition keyed
-on the cover art element so the small tile appears to grow into the
-big cover. The same primitive already used by `ViewTransitionLink`.
-
-### Shared player primitives
-
-`web/src/player/components/` already houses the visual building blocks
-used by the video player. Two of them get extracted so both players
-consume the same source of truth:
-
-| File | Status | Purpose |
-|---|---|---|
-| `SeekBar.tsx` | reused as-is | already shared |
-| `ChaptersMenu.tsx` | reused as-is | already shared |
-| `CircleButton.tsx` | **new** — extracted from `PlayerControls.tsx` | the glass-disc primary/secondary button used in both transport clusters |
-| `SpeedMenu.tsx` | **new** | popover speed menu matching the styling of `ChaptersMenu`; replaces the raw `<select>` today; video player can adopt later |
-| `SleepTimerMenu.tsx` | **new** | popover with off / 5 / 15 / 30 / 45 / 60 / end-of-chapter; audiobook-only but lives here for symmetry |
-
-Extracting `CircleButton` removes a divergence rather than adding a
-layer — it's the kind of focused improvement that earns its keep
-because today the video player and the audiobook player each render
-their own visually-similar-but-not-identical disc buttons.
-
-### Audiobook player component tree
-
-```
-web/src/pages/audiobooks/
-  AudiobookDetail.tsx              (restructured per "Detail page" below)
-  AudiobookLibrary.tsx             (unchanged)
-  player/                          (new folder)
-    AudiobookPlayer.tsx            (top level: owns audio element and state)
-    MiniBar.tsx                    (compact chrome)
-    NowListening.tsx               (overlay chrome)
-    CoverExpandTile.tsx            (left-edge tile inside MiniBar — also the view-transition anchor)
-    useAudiobookPlayback.ts        (state hook: audio events, progress reporting, sleep timer)
-```
-
-`AudiobookPlayer` becomes a thin shell:
-
-```tsx
-function AudiobookPlayer(props) {
-  const playback = useAudiobookPlayback(props);
-  const [mode, setMode] = useState<"mini" | "now-listening">("mini");
-  return (
-    <>
-      <audio ref={playback.audioRef} src={playback.streamUrl} preload="metadata" hidden />
-      {mode === "mini"
-        ? <MiniBar playback={playback} onExpand={() => setMode("now-listening")} onClose={props.onClose} />
-        : <NowListening playback={playback} onCollapse={() => setMode("mini")} />}
-    </>
-  );
-}
-```
-
-The audio element lives in the parent so a mode swap never touches it.
-
-### useAudiobookPlayback responsibilities
-
-Lifts today's monolithic `AudiobookPlayer.tsx` into a single hook
-returning a stable shape:
-
-```ts
-{
-  audioRef,                       // ref<HTMLAudioElement>
-  streamUrl,                      // string
-  playing, currentTime, duration, buffered, rate,
-  chapters,                       // PlayerChapter[] (flattened across files)
-  currentChapter,                 // PlayerChapter | null
-  sleep,                          // { remainingMs: number | null, end: SleepEndCondition | null }
-  togglePlay, seekTo, skip,
-  setRate,
-  setSleep,                       // arms the timer
-  // bookmarks (v1.1 — initially returns []/no-op stubs)
-  bookmarks, addBookmark, removeBookmark,
-}
-```
-
-The hook owns: audio event wiring, periodic progress reporting (the
-existing 10s `useReportAudiobookProgress` cadence), sleep-timer state
-+ fade-out, computing `currentChapter` from `currentTime`, and the
-unmount-time pause + final report. The chrome components stay pure
-presentational.
-
-## Mini bar
-
-Layout (one seek-bar row above a controls row):
-
-```
-[ full-width SeekBar with chapter ticks ]
-[ cover tile | title + chapter + time | ◀30 ▶❚❚ 30▶ | ⌛ ☰ 1× ⌃ ✕ ]
-   ↑ left col       middle              center           right rail
-   36×54px          truncating          shared CircleButton cluster
-                                                            sleep, chapters, speed,
-                                                            expand chevron, close
-                                                            (bookmark hidden in v1)
-```
-
-Differences from today's implementation:
-
-- **CoverExpandTile** added at the left edge. 36×54 (portrait
-  aspect-2:3). On hover: subtle scale + a small "expand" chevron
-  overlay. Clicking it triggers the view transition to Now Listening.
-- **Left text column** shows title (line 1) and current chapter title
-  (line 2). Time row stays where it is. Today the chapter title isn't
-  shown anywhere while playing — this is the single most useful
-  "where am I" cue and it's missing.
-- **Center cluster** swaps the bespoke `CircleButton` defined inline
-  in the current `AudiobookPlayer` for the extracted shared one. Same
-  three controls (back 30 / play-pause / forward 30).
-- **Right rail** replaces the raw `<select>` for speed with
-  `SpeedMenu` (popover, same styling as `ChaptersMenu`). Adds
-  `SleepTimerMenu`, an expand-up chevron (`ChevronUp`), and the
-  existing close `X`. The bookmark button is **hidden in v1** (mini
-  bar has no bookmark control until v1.1 lands).
-
-Mini bar height is unchanged from today.
-
-## Now Listening overlay
-
-Full-viewport overlay, dark surface (`bg-background`). Z-index above
-the mini bar, below modals.

-
-Layout on mobile (portrait): same elements stacked top-to-bottom —
-header row, cover (centered, smaller), metadata block, seek bar,
-transport, utility row. No horizontal split.
-
-Key behaviors:
-
-- **Tap right time** toggles between `-remaining` and the wall-clock
-  end time. The toggle preference is in-memory only (resets per
-  session) — no persistence concern.
-- **Sleep timer** opens `SleepTimerMenu`. When armed, the trigger
-  shows the countdown (`Sleep 04:32`). When the timer hits zero the
-  player fades volume to 0 over 5s and pauses.
-- **Car mode** and **bookmark** buttons are **hidden in v1** — the
-  utility row ships with sleep / chapters / speed only. Car mode +
-  bookmark slots are documented here so v1.1 has a clear home for
-  them.
-- **Overflow ⋯** menu items for v1: "Go to detail page", "Report a
-  sync problem" (opens a mailto/issue link). Future additions live
-  here.
-
-The same `<audio>` element backs both modes, so all controls in Now
-Listening are bound to the same `useAudiobookPlayback` state.
-
-## Detail page restructure
-
-The page keeps its current top-level shape (hero band + content
-below) and adds/rearranges these blocks:
-
-### Hero band
-
-Today: `DetailHero` with a stack of `Play` / `Play from Start`
-actions and a small progress bar that appears below the buttons only
-when progress exists.
-
-New version (still using `DetailHero` but with a richer `actions`
-slot):
-
-```
-[ progress bar — full width of actions column, always shown if any progress ]
-[ "3h 12m listened · 19%" caption ]
-
-▶ Resume Ch 7 · The Astrophage     ↻ Start Over     🔖 Bookmarks (3)
-```
-
-- Progress bar moves up *above* the buttons so the listener sees
-  position context first.
-- Resume button label includes the chapter the listener will land
-  in. Pulled from the same `buildChapterList` already in the file.
-- "Bookmarks (n)" button visible only when n > 0; opens a side sheet
-  listing them. v1 ships with an empty stub (always 0, button never
-  shown) — full feature in v1.1.
-
-### Chapters section
-
-Today: collapsed-by-default disclosure showing a chapter list.
-
-New version:
-
-- Expanded by default. (Collapsed in this position made sense when
-  the page was sparse; once we're foregrounding chapter awareness
-  everywhere else, hiding the list here is contradictory.)
-- Currently-playing chapter row gets a left-edge accent and a
-  "▶ playing" badge on the right.
-- Lightweight sort menu in the section header: "By position" (default),
-  "Longest first" — no UI for "By title" since chapter titles rarely
-  sort meaningfully. Sort preference is in-memory only for v1.
-- Clicking a chapter row still calls `openPlayer(absoluteStart)` as
-  today; if the player is open, it seeks rather than reopens.
-
-### Narrator card
-
-New section between Chapters and the cross-rails. Renders only when
-`data.narrator` is non-empty.
-
-```
-── NARRATOR ──
-[ avatar 64×64 ]  Ray Porter
-                   47 audiobooks in your library  →
-```
-
-Avatar source: if the absorbed audiobook data model exposes a
-narrator photo, use it; otherwise an initials avatar in a circle.
-The `→` link goes to a narrator detail page if one exists, or a
-search-results page filtered by narrator name as a fallback.
-
-### Cross-book rails
-
-Three sections, each rendered only when its data is present, ordered
-top-to-bottom:
-
-- **"Similar audiobooks"** — embedding-based recommendations. Ranked
-  by vector similarity against this book; ordering and inclusion
-  decided server-side. Renders with a subtitle "Based on listening
-  patterns" to give the rail a small bit of provenance copy that the
-  metadata rails don't need.
-- **"Also by {author}"** — horizontal scroller of cover tiles, same
-  pattern as `MediaRow` used elsewhere in Silo.
-- **"In this series"** — same pattern, with "Book n of m" subtitle and
-  the current book non-clickable / highlighted.
-
-All three rails ship behind feature-detection: if the API response
-for the book includes the related array, render it; if not, hide the
-section without showing a placeholder. This avoids blocking v1 on any
-specific backend rail support — each lights up as the data lands.
-
-### What's *not* in the new detail page
-
-- Reviews / ratings — out of scope, not in the data model.
-- Tabs — page is short enough that one scroll surface beats tabs.
-- Social / cohost listening — no signal it's wanted.
-
-## Data & API impact
-
-Most of the work is pure frontend, but three small backend-adjacent
-items to call out:
-
-| Item | Impact |
-|---|---|
-| Sleep timer | Frontend-only. No API change. |
-| Speed menu | Frontend-only — already a client-side audio setting. |
-| Bookmarks | **Deferred to v1.1.** Needs `audiobook_bookmarks` table (`content_id`, `profile_id`, `position_seconds`, `note`, `created_at`) plus CRUD endpoints. v1 ships with the button hidden and `useAudiobookPlayback` exposing no-op bookmark stubs. |
-| Narrator card with "n audiobooks in library" count | Needs narrator-aware query. If the detail endpoint already returns it, render; otherwise hide the count line and show only the name. |
-| "Also by author" / "In this series" rails | Render only when arrays present. v1 doesn't require backend changes — it just adapts to whatever the response contains. |
-| "Similar audiobooks" rail (embedding-based) | Render only when `similar_audiobooks` array present on the detail response. Backend computes similarity from per-book embeddings server-side and includes the top-N already ranked. v1 frontend has no embedding logic — it just renders whatever ordered list the API returns. |
-
-## Routing & view-transition wiring
-
-- `/audiobooks/book/:contentId` continues to be the only audiobook
-  route added by this work. Mini bar and Now Listening are layered
-  inside this route's component tree.
-- View transition name: `audiobook-cover-{contentId}`. Set on the
-  cover tile inside `CoverExpandTile` and on the large cover element
-  inside `NowListening`. Same `contentId` on both = the browser
-  animates the rect change automatically.
-- The detail page's hero cover and the mini bar's cover tile share
-  the same view-transition name so the *initial* open (clicking
-  Play/Resume on the hero) also animates the cover into the mini bar
-  position.
-
-## Accessibility
-
-- All transport controls have `aria-label`s (already true today; keep
-  parity).
-- The expand chevron and the cover tile are both labeled "Expand
-  player" / "Open Now Listening" — two ways in, both discoverable to
-  screen readers.
-- `SleepTimerMenu`, `SpeedMenu`, `ChaptersMenu` use the existing
-  `Popover` primitive with proper roving focus + Escape-to-close
-  (inherits from `ChaptersMenu` behavior).
-- Now Listening overlay traps focus while open and restores focus to
-  the mini bar's expand chevron on close.
-- Color contrast for the chapter-title text in the mini bar must
-  meet WCAG AA against the bar's background (use `text-foreground`
-  with a `text-muted-foreground` chapter title is the existing
-  pattern and passes).
-
-## Testing
-
-- **Unit:** `useAudiobookPlayback` — chapter computation from current
-  time across multi-file audiobooks, sleep-timer arm/disarm/fire,
-  progress reporting cadence and pause/seek/end triggers.
-- **Component:** `MiniBar` and `NowListening` render expected
-  elements given a mocked playback object; expand/collapse calls the
-  right callbacks; speed menu / sleep menu open and emit the right
-  values.
-- **Integration / Playwright** (if the repo has Playwright wired for
-  these flows): start playback from detail page → mini bar appears
-  with chapter title → click cover tile → Now Listening overlay
-  appears → seek bar works in both modes → collapse returns to mini
-  bar with playback uninterrupted (key assertion: `audio.currentTime`
-  monotonically advances across the mode swap).
-
-## Out of scope (recap)
-
-- Bookmarks backend (v1.1 sub-spec)
-- Cross-book rails backend joins
-- Car mode full layout
-- Audiobook library grid redesign
-- Lifting the player to an app-level provider so it survives
-  navigation away from the detail page
-
-## Open questions / risks
-
-- **Multi-file audiobooks.** Today's player only plays `files[0]` —
-  multi-file audiobooks display all chapters but can't actually cross
-  file boundaries. This redesign doesn't fix that; it inherits the
-  limitation. Worth flagging in the implementation plan whether to
-  fold a fix into v1 or leave it for a separate ticket.
-- **View transition browser support.** CSS view transitions are
-  supported in modern Chromium and Safari Tech Preview; Firefox is
-  not there yet. The mini ↔ Now Listening swap must work without
-  the transition (graceful fallback to a plain unmount/mount).
-- **Sleep-timer fade.** A 5s gain ramp on `HTMLAudioElement.volume`
-  works but is not as smooth as a Web Audio API gain node. Starting
-  simple; revisit if it feels janky.

-# ABS Bookmarks — Phase 1 Sub-Project 1
-
-**Status:** Approved 2026-05-26. Ready for implementation plan.
-**Scope:** First sub-project of Phase 1 (per `2026-05-26-abs-implementation-fix-design.md`).
-**Predecessor spec:** `docs/superpowers/specs/2026-05-26-abs-implementation-fix-design.md` §"Phase 1 — Feature surface completion" → Bookmarks bullet.
-
-Commands in this document assume the repository root is the cwd.
-
-## 1. Goal
-
-Let an Audiobookshelf mobile client (official Android, official iOS, and well-behaved third parties such as Plappa) create, edit, and delete in-book bookmarks against a silo audiobook library, and see those bookmarks sync in real time to the user's other connected devices.
-
-## 2. Non-goals
-
-- No ebook bookmarks (audiobook only — matches ABS's own surface).
-- No bulk bookmark import / export, no merge-by-title, no fuzzy time matching.
-- No `/api/me/bookmarks` aggregate-list endpoint. The Android client only calls per-item endpoints; adding the aggregate would be dead code today.
-- No client UI work — silo's web admin doesn't ship a bookmarks view yet, and the mobile clients already render bookmarks from these endpoints.
-- No socket-server overhaul; Phase 1 just publishes events through the existing `Handler.publish` wrapper. Phase 2 covers the full socket event surface.
-
-## 3. Architecture
-
-Three ABS-compatible REST handlers + one socket event family + one migration.
-
-- **HTTP layer:** new `internal/audiobooks/abs/bookmarks_handler.go` alongside existing `items_handler.go` / `progress.go`. Handler-method pattern mirrors `handleSetItemProgress`. Routes registered under both `/abs/api` and `/api` prefixes inside the existing bearerAuth group.
-- **Storage layer:** new `BookmarkStore` interface in `internal/audiobooks/abs/bookmarks.go` (split out rather than crowd `progress.go`) plus a concrete `ABSBookmarkStore` Postgres implementation in `internal/audiobooks/abs_bookmark_store.go` — naming mirrors `abs_playback_session_store.go`. Wiring lives in `internal/audiobooks/service.go`, alongside the other store constructions in `BuildABSHandler`.
-- **Migration:** `migrations/148_abs_bookmarks.up.sql` + `.down.sql`.
-- **Socket events:** the existing nil-safe `Handler.publish(userID, event, payload)` wrapper. Each handler fires `user_updated` with a `reason` discriminator on success — three lines per handler. No new event publisher code.
-
-## 4. Endpoint surface
-
-All mounted at both `/abs/api/*` and `/api/*` inside the bearerAuth group.
-
-| Verb | Path | Body | Returns |
-|---|---|---|---|
-| POST | `/me/item/{itemId}/bookmark` | `{title, time}` | full item bookmark list |
-| PATCH | `/me/item/{itemId}/bookmark` | `{title, time}` | full item bookmark list (upserts at `time`) |
-| DELETE | `/me/item/{itemId}/bookmark/{time}` | — | full item bookmark list (idempotent) |
-
-All three handlers fire `user_updated` on success with the relevant `reason`:
-
-| Handler | `reason` value |
-|---|---|
-| Create | `bookmark_created` |
-| Update | `bookmark_updated` |
-| Delete | `bookmark_deleted` |
-
-Socket event payload shape:
-
-```json
-{
-  "reason": "bookmark_created",
-  "bookmark": { "id": "01K…", "libraryItemId": "126887…", "time": 1234.5, "title": "Cliffhanger", "createdAt": 1779786284823, "updatedAt": 1779786284823 }
-}
-```
-
-For `bookmark_deleted`, `bookmark.title` is the pre-delete title; for `bookmark_created` / `bookmark_updated` it is the freshly-persisted row.
-
-### 4.1 Wire shape
-
-```json
-{
-  "id": "01KSHR…",
-  "libraryItemId": "126887440911695876",
-  "time": 1234.5,
-  "title": "Good cliffhanger",
-  "createdAt": 1779786284823,
-  "updatedAt": 1779786284823
-}
-```
-
-- All six fields always present (never `omitempty`).
-- `time` is fractional seconds (`double`).
-- `createdAt` / `updatedAt` are JS-epoch milliseconds (`int64`), matching every other ABS handler's timestamp emission.
-- Empty title serializes as `"title": ""`.
-
-### 4.2 Why no GET-list endpoint
-
-The canonical continuum plugin handler, the Android `BookmarksModal.vue`, booklore-ng's per-item route, and the official ABS server all return the full item bookmark list from the mutating endpoints. A separate `GET /me/item/{id}/bookmark` would be dead code.
-
-## 5. Data model
-
-### 5.1 Migration 148_abs_bookmarks
-
-`migrations/148_abs_bookmarks.up.sql`:
-
-```sql
-CREATE TABLE abs_bookmarks (
-    id              text PRIMARY KEY,
-    user_id         integer NOT NULL,
-    profile_id      uuid,
-    library_item_id text NOT NULL,
-    time_seconds    double precision NOT NULL,
-    title           text NOT NULL DEFAULT '',
-    created_at      timestamptz NOT NULL DEFAULT now(),
-    updated_at      timestamptz NOT NULL DEFAULT now()
-);
-
-CREATE UNIQUE INDEX abs_bookmarks_user_profile_item_time_uniq
-    ON abs_bookmarks (
-        user_id,
-        COALESCE(profile_id, '00000000-0000-0000-0000-000000000000'::uuid),
-        library_item_id,
-        time_seconds
-    );
-
-CREATE INDEX abs_bookmarks_user_item_idx
-    ON abs_bookmarks (user_id, library_item_id);
-```
-
-`migrations/148_abs_bookmarks.down.sql`:
-
-```sql
-DROP TABLE abs_bookmarks;
-```
-
-### 5.2 Schema rationale
-
-- **`id` text (ULID), not UUID** — matches every other ABS surface ID emitted by silo (`abs_tokens.id`, `abs_playback_sessions.id`). Clients get a consistent shape; ULIDs are also lexicographically sortable by creation time, which simplifies debug output.
-- **`profile_id` nullable, with COALESCE sentinel in the unique index** — silo's primary-profile convention is `NULL` profile. Postgres treats raw `NULL` as distinct for uniqueness, so the COALESCE-to-fixed-UUID trick collapses NULL to a single bucket per user, which is what makes "one bookmark per timestamp per profile" work.
-- **Unique on `(user, profile, item, time)`** — encodes the "one bookmark per timestamp" invariant directly, which is what makes `Upsert(...,time,title)` the natural primitive: PATCH at an existing time updates the title; PATCH at a new time creates.
-- **Secondary index on `(user_id, library_item_id)`** — covers the hot-path `List` query that runs after every mutation. Avoids a sort or full scan when a user has many bookmarks across many items.
-- **`title` NOT NULL DEFAULT ''** — Android lets users create quick bookmarks without a title; empty string stores cleanly. Avoids null-guard branches in client iteration code.
-
-### 5.3 Go model
-
-```go
-type Bookmark struct {
-    ID            string    // ULID
-    LibraryItemID string
-    Time          float64   // fractional seconds
-    Title         string
-    CreatedAt     time.Time
-    UpdatedAt     time.Time
-}
-```
-
-Handlers convert to the wire shape (camelCase JSON keys, timestamps as `UnixMilli()`).
-
-## 6. Storage contract
-
-```go
-type BookmarkStore interface {
-    // List returns all bookmarks for (user, profile, item) ordered by time
-    // ASC. Empty slice (never nil) when none exist.
-    List(ctx context.Context, userID, profileID, itemID string) ([]Bookmark, error)
-
-    // Upsert inserts a bookmark or updates the title at the exact
-    // (user, profile, item, time) tuple. ID is generated on insert and
-    // preserved on update. Returns the resulting row.
-    Upsert(ctx context.Context, userID, profileID, itemID string, time float64, title string) (Bookmark, error)
-
-    // Delete removes the bookmark at (user, profile, item, time). Returns
-    // nil when no row matched — DELETE is idempotent (a UX convenience,
-    // not a 404 surface).
-    Delete(ctx context.Context, userID, profileID, itemID string, time float64) error
-}
-```
-
-**Behavior:**
-
-- `Upsert` uses a single `INSERT ... ON CONFLICT (user_id, COALESCE(profile_id,'…'), library_item_id, time_seconds) DO UPDATE SET title = EXCLUDED.title, updated_at = now() RETURNING *` — one round-trip, no read-then-write race.
-- `List` sort happens in SQL (`ORDER BY time_seconds ASC`), not in Go.
-- Profile mapping: handlers pass `a.ProfileID` (string, empty = primary) straight through to the store; the store maps empty → NULL on writes and uses the same COALESCE-to-sentinel-UUID trick on reads. Mirrors the pattern already used by `abs_session_store.go` (`*string` round-trip) — pick whichever pgx approach reads cleanest in the impl, just keep the empty-as-primary convention consistent with the rest of `internal/audiobooks/`.
-- Time precision: exact float64 equality on PATCH/DELETE-at-time. Plappa and the official client always echo back the exact value they received, so epsilon comparison would be complexity nothing exercises.
-- `Delete` on a non-existent row returns `nil`. The caller still re-fetches the list and returns it, so double-tapped deletes produce consistent state.
-
-## 7. Error model
-
-| Condition | Status | Body |
-|---|---|---|
-| Missing/invalid bearer | 401 | handled by `bearerAuth` middleware |
-| Body decode failure (POST/PATCH) | 400 | `invalid body` |
-| `time` missing or NaN | 400 | `time required` |
-| `itemId` not in `MediaStore` | 404 | `item not found` |
-| Store upsert / mutate fails | 500 | sanitized `bookmark persist failed`; err logged via `slog.Error` |
-| Store delete fails (DB error, not missing row) | 500 | sanitized `bookmark delete failed` |
-| List fetch fails after a successful mutation | 200 + empty `[]` + `slog.Warn` | mutation already committed; returning empty list beats 500 |
-
-**Cross-cutting:**
-
-- **No leaked-existence side channel.** DELETE for a bookmark belonging to another user/profile returns 200 with the caller's list (which doesn't contain the target) — indistinguishable from DELETE for a non-existent bookmark. No 403, no enumeration vector.
-- **Item validation.** Validate `itemId` via `MediaStore.GetAudiobookByID` before touching the store (same pattern as `handleItem`). Catches typos and deleted items early; avoids orphan bookmark rows whose item no longer exists.
-- **Body size limit.** Request body wrapped in `io.LimitReader(r.Body, 1<<20)` — same 1 MiB cap as `handleStandaloneLogin`.
-- **Socket publish never fails the request.** `h.publish(...)` is nil-safe and fire-and-forget; if the Publisher is unwired the response still completes.

-| `ProfileIsolation_BookmarksScopedPerProfile` | (user, profile A) POST → (user, profile B) List returns empty |
-| `MissingItem_404` | POST against unknown itemId → 404 |
-| `InvalidBody_400` | POST with malformed JSON → 400, no DB write |
-| `MissingTime_400` | POST with body `{title:"x"}` (no time) → 400 |
-| `SocketEvent_FiredOnCreate` | mock `EventPublisher` captures the publish; assert userID + `user_updated` + `reason:"bookmark_created"` |

-One marshal test that takes a `Bookmark` (including the empty-title case) and asserts every required JSON key is present and uses the camelCase spelling: `id`, `libraryItemId`, `time`, `title`, `createdAt`, `updatedAt`. Mirrors the existing `TestSiloItemToMetadata_JSONKeysAlwaysPresent` and `TestLoginEnvelope_HasRequiredKeys` patterns.
-
-### 8.3 Live integration smoke (post-deploy)

-
-Expected: each call returns the updated list; the final DELETE returns `[]`.
-
-### 8.4 Explicitly out-of-scope
-
-- No real-Postgres integration test for the SQL. The `ON CONFLICT` clause and unique-index COALESCE behavior are small enough that the in-memory fake covers the semantics; CI does not currently run a Postgres for the ABS subdomain.
-- No load test. Bookmark mutations are user-driven and rare (handful per session).
-
-## 9. Risks & open questions
-
-- **Time-precision collision risk.** If a future client rounds `time` differently between POST and DELETE (e.g. POST sends `42.500001`, DELETE sends `42.5`), the DELETE would silently no-op. Acceptable for the current client set (Android and official iOS echo exactly), but worth a comment on the `Delete` method so future-us doesn't burn time chasing a ghost.
-- **No migration rollback test.** The `.down.sql` is one `DROP TABLE` — low risk — but the migration suite doesn't currently exercise rolls. Same posture as recent migrations; not a blocker.
-- **Bookmark fan-out on socket events.** `Handler.publish(userID, ...)` targets the user room. If the user has many connected sockets, the publish fans out per-socket. Volume here is trivial (manual user action). No backpressure concern at Phase 1 scale.
-
-## 10. Out-of-scope follow-ups
-
-These are intentionally deferred — they belong to later Phase 1 sub-projects or Phase 2:
-
-- Aggregate `GET /api/me/bookmarks` (caller's full bookmark inventory). Adds value only when a "Bookmarks" tab lands in a client that needs it.
-- Hydrating `user.bookmarks` in the `/login` envelope. Currently emits `[]` placeholder; populating costs a join on every login and only matters to clients that read from there at startup.
-- Embedding `bookmarks` on item-detail (`GET /api/items/{id}`). The Android player fetches its bookmarks via the per-item bookmark endpoint on modal-open, not from item-detail.
-
-## 11. References
-
-- Spec parent: `docs/superpowers/specs/2026-05-26-abs-implementation-fix-design.md`.
-- Wire-shape reference (canonical, working against real ABS Android): the continuum-plugin-audiobooks `bookmarks_handler.go` + the `r.Post/Patch/Delete` mounts in its `handler.go`. Diff against silo before flagging response-shape concerns.
-- Client wire usage: `audiobookshelf-app/components/modals/BookmarksModal.vue` (the only place the official client builds bookmark requests).
-- Booklore-ng has its own `me/bookmarks` aggregate endpoint that the official client does not use; ignored here.

-# ABS Collections + Playlists — Phase 1 Sub-Project 2
-
-**Status:** Approved 2026-05-26. Ready for implementation plan.
-**Scope:** Second sub-project of Phase 1 (per `2026-05-26-abs-implementation-fix-design.md`).
-**Predecessor spec:** `docs/superpowers/specs/2026-05-26-abs-implementation-fix-design.md` §"Phase 1 — Feature surface completion" → Manual Collections + Playlists bullets.
-**Sibling sub-project:** `docs/superpowers/specs/2026-05-26-abs-bookmarks-design.md` (sub-project 1; the bookmarks data model, in-memory test fakes, store wiring, and error-handling conventions established there are reused here without re-justification).
-
-Commands in this document assume the repository root is the cwd.
-
-## 1. Goal
-
-Land manual user collections and ordered playlists on the silo audiobook surface so the official Audiobookshelf Android, iOS, and Plappa clients can create, browse, mutate, and share named groupings of audiobooks. "Manual collection" means a user-curated unordered set of audiobooks with a name + description (think: "Favorites", "To Read"). "Playlist" means an ordered queue with a cover image (think: "Wind-down listening"). Both are owned by a profile, optionally public to other users on the same silo instance.
-
-## 2. Non-goals
-
-- **No podcast episode hydration.** Playlist items accept and echo `episodeId`, but only audiobook items are looked up in `MediaStore`. A future sub-project will wire `internal/audiobooks/podcastfeed` hydration.
-- **No reorder API.** Clients simulate reorder via remove+add (the re-added item lands at the end).
-- **No smart collections.** Those are sub-project 3 (separate `query_def` storage + DSL evaluator).
-- **No silo-web UI.** The web admin doesn't ship a collections/playlists view yet; ABS mobile clients render these.
-- **No socket-server overhaul.** Playlists publish three existing-pattern events; collections publish none. Full socket parity is Phase 2 of the parent spec.
-
-## 3. Architecture
-
-Two REST surfaces sharing a uniform shape, mounted under `/abs/api/*` and `/api/*` inside the existing `bearerAuth` group.
-
-- **HTTP layer:**
-  - `internal/audiobooks/abs/collections_handler.go` — 7 routes (list, create, get, update, delete, add item, remove item).
-  - `internal/audiobooks/abs/playlists_handler.go` — 9 routes (list, create, get, update, delete, add single item, batch add, batch remove, remove single item; remove-episode variant uses two URL params).
-- **Storage layer:**
-  - New interfaces in `internal/audiobooks/abs/collections.go` and `playlists.go` (one file each, parallel to `bookmarks.go`):
-    - `CollectionStore` — `ListUserCollections / GetCollection / CreateCollection / UpdateCollection / DeleteCollection / ListCollectionItems / AddCollectionItem / RemoveCollectionItem`.
-    - `PlaylistStore` — `ListUserPlaylists / GetPlaylist / CreatePlaylist / UpdatePlaylist / DeletePlaylist / ListPlaylistItems / AddPlaylistItem / RemovePlaylistItem`.
-  - Concrete pgx impls in `internal/audiobooks/abs_collection_store.go` and `abs_playlist_store.go` (parallel to `abs_bookmark_store.go`).
-- **Migrations** (paired up/down per `CLAUDE.md`):
-  - `149_abs_user_collections`, `150_abs_collection_items`, `151_abs_playlists`, `152_abs_playlist_items`.
-- **Socket events:** Playlists publish `playlist_added` / `playlist_updated` / `playlist_removed` (continuum-canonical event names). Collections publish nothing. All publishes go through the existing nil-safe `Handler.publish(...)` wrapper.
-- **Service wiring:** Both new stores wired in `BuildABSHandler` (mirrors the BookmarkStore wiring landed in sub-project 1).
-
-## 4. Endpoint surface
-
-All routes mounted under both `/abs/api/*` and `/api/*` inside `bearerAuth`. Success status code is **200 OK** in every row of the tables below, except where the `Returns` column explicitly says **204 No Content** (DELETE collection / DELETE playlist themselves; the item-mutation DELETEs return 200 with the parent's full-shape body, matching continuum).
-
-### 4.1 Collections (7 routes)
-
-| Verb | Path | Body | Returns |
-|---|---|---|---|
-| GET | `/collections` | — | `{"collections": [Collection list-shape]}` |
-| POST | `/collections` | `{name, description, isPublic?}` | Collection full-shape |
-| GET | `/collections/{id}` | — | Collection full-shape when caller is owner, OR when `is_public=true`; otherwise 404 |
-| PATCH | `/collections/{id}` | `{name?, description?, isPublic?}` | Collection full-shape |
-| DELETE | `/collections/{id}` | — | 204 No Content |
-| POST | `/collections/{id}/book/{bookId}` | — | Collection full-shape (with updated `books[]`) |
-| DELETE | `/collections/{id}/book/{bookId}` | — | Collection full-shape |
-
-### 4.2 Playlists (9 routes)
-
-| Verb | Path | Body | Returns |
-|---|---|---|---|
-| GET | `/playlists` | — | `{"playlists": [Playlist list-shape]}` |
-| POST | `/playlists` | `{name, description, cover_item?, isPublic?}` | Playlist full-shape |
-| GET | `/playlists/{id}` | — | Playlist full-shape when caller is owner, OR when `is_public=true`; otherwise 404 |
-| PATCH | `/playlists/{id}` | `{name?, description?, cover_item?, isPublic?}` | Playlist full-shape |
-| DELETE | `/playlists/{id}` | — | 204 No Content |
-| POST | `/playlists/{id}/item` | `{libraryItemId, episodeId?}` | Playlist full-shape |
-| POST | `/playlists/{id}/batch/add` | `{items: [{libraryItemId, episodeId?}]}` | Playlist full-shape |
-| POST | `/playlists/{id}/batch/remove` | `{items: [{libraryItemId, episodeId?}]}` | Playlist full-shape |
-| DELETE | `/playlists/{id}/item/{libraryItemId}` | — | Playlist full-shape |
-| DELETE | `/playlists/{id}/item/{libraryItemId}/{episodeId}` | — | Playlist full-shape |
-
-### 4.3 Wire shape — Collection
-
-**List shape (no `books[]`):**
-
-```json
-{
-  "id": "01HXXX",
-  "userId": "1",
-  "name": "Favorites",
-  "description": "My top picks",
-  "isPublic": false,
-  "lastUpdate": 1779786284823,
-  "createdAt": 1779786284823
-}
-```
-
-**Full shape (with `books[]`):**
-
-```json
-{
-  "id": "01HXXX",
-  "userId": "1",
-  "name": "Favorites",
-  "description": "My top picks",
-  "isPublic": false,
-  "lastUpdate": 1779786284823,
-  "createdAt": 1779786284823,
-  "books": [
-    {
-      "id": "126887...",
-      "libraryId": "9",
-      "media": { "metadata": { "title": "Book Title", "authors": [...] } }
-    }
-  ]
-}
-```
-
-All seven top-level keys always present (`description` is `""` when unset, never omitted — fixes the continuum-reference bug where description was always emitted as empty regardless of stored value). `books[]` is always an array (possibly empty) on the full shape; omitted on the list shape.
-
-### 4.4 Wire shape — Playlist
-
-**List shape (no `items[]`):**
-
-```json
-{
-  "id": "01HXXX",
-  "userId": "1",
-  "name": "My Queue",
-  "description": "",
-  "isPublic": false,
-  "coverPath": "126887...",
-  "createdAt": 1779786284823,
-  "lastUpdate": 1779786284823
-}
-```
-
-**Full shape (with `items[]`):**
-
-```json
-{
-  "id": "01HXXX",
-  "userId": "1",
-  "name": "My Queue",
-  "description": "",
-  "isPublic": false,
-  "coverPath": "126887...",
-  "createdAt": 1779786284823,
-  "lastUpdate": 1779786284823,
-  "items": [
-    { "libraryItemId": "126887...", "position": 0, "title": "Book Title", "libraryId": "9" },
-    { "libraryItemId": "podcast-x",  "episodeId": "ep-1", "position": 1 }
-  ]
-}
-```
-
-`coverPath` is emitted when set; omitted when unset. `description` always present. Items always sorted by `position` ASC. Entries with `episodeId` set are emitted with the field; audiobook entries omit it. Audiobook items hydrate `title` + `libraryId` via `MediaStore.GetAudiobookByID`; episode items emit the bare reference.
-
-### 4.5 Hydration semantics
-
-- `MediaStore.GetAudiobookByID(libraryItemId)` is called per book on the **full** shape only (the list shape skips it to keep response sizes small).
-- On miss (item deleted between collection/playlist mutation and list-fetch), the entry degrades to `{id, libraryId}` only — clients render a placeholder.
-- `libraryId` resolution: same `resolveDefaultLibrary` helper from `items_handler.go` (returns numeric library ID as decimal string).
-
-### 4.6 Socket events
-
-| Event | When | Payload |
-|---|---|---|
-| `playlist_added` | After POST `/playlists` | `{id, name}` |
-| `playlist_updated` | After PATCH or any item mutation (single or batch) | `{id}` |
-| `playlist_removed` | After DELETE `/playlists/{id}` | `{id}` |
-
-Collections fire no socket events (matches continuum; Phase 2 of the parent spec covers full event parity).

-
-### 5.5 Schema rationale
-
-- **`is_public boolean`** — cross-user-public read semantics. `false` default. List endpoints never expose other users' rows; GET-by-id allows non-owner reads only when `is_public = true`.
-- **Collection items: FK + CASCADE on `library_item_id`** — when a book is deleted from the library, drop it from all collections (clean orphan-free state). Same pattern as migration 143's `abs_playback_sessions.content_id`.
-- **Collection items: composite PK on `(collection_id, library_item_id)`** — enforces "a book appears at most once in a collection" without a synthetic ID.
-- **Playlist items: `library_item_id` NOT FK'd** — collections enforce one-shot membership; playlists are ordered queues that may legitimately reference items the user hasn't bookmarked. Decoupling lets a future migration FK it when episode support lands properly. Today: handler validates via MediaStore (same pattern as bookmarks).
-- **Playlist items: `episode_id text NOT NULL DEFAULT ''`** — empty string for audiobook items, populated for podcast episodes. Empty-string-default lets `(playlist_id, library_item_id, episode_id)` be a clean unique key without COALESCE.
-- **Playlist items: no synthetic ID** — `(playlist_id, library_item_id, episode_id)` is naturally unique; `position` is sort hint (gaps allowed when items are removed).
-- **`cover_item REFERENCES media_items(content_id) ON DELETE SET NULL`** — playlist survives cover-item deletion; cover gracefully becomes nothing.
-
-### 5.6 Go models
-
-```go
-type Collection struct {
-    ID          string
-    UserID      string
-    ProfileID   string
-    Name        string
-    Description string
-    IsPublic    bool
-    CreatedAt   time.Time
-    UpdatedAt   time.Time
-}
-
-type CollectionItem struct {
-    CollectionID  string
-    LibraryItemID string
-    AddedAt       time.Time
-}
-
-type Playlist struct {
-    ID          string
-    UserID      string
-    ProfileID   string
-    Name        string
-    Description string
-    CoverItem   string  // empty when unset
-    IsPublic    bool
-    CreatedAt   time.Time
-    UpdatedAt   time.Time
-}
-
-type PlaylistItem struct {
-    PlaylistID    string
-    LibraryItemID string
-    EpisodeID     string  // empty for audiobook items
-    Position      int
-    AddedAt       time.Time
-}
-```
-
-Handlers convert these to the wire shape (camelCase JSON keys, timestamps as `UnixMilli()`).
-
-## 6. Storage contract
-
-### 6.1 `CollectionStore` (in `internal/audiobooks/abs/collections.go`)
-
-```go
-type CollectionStore interface {
-    ListUserCollections(ctx context.Context, userID, profileID string) ([]Collection, error)
-    GetCollection(ctx context.Context, id string) (Collection, error)
-    CreateCollection(ctx context.Context, c Collection) error
-    UpdateCollection(ctx context.Context, c Collection) error
-    DeleteCollection(ctx context.Context, id string) error
-    ListCollectionItems(ctx context.Context, collectionID string) ([]CollectionItem, error)
-    AddCollectionItem(ctx context.Context, collectionID, libraryItemID string) error
-    RemoveCollectionItem(ctx context.Context, collectionID, libraryItemID string) error
-}
-```
-
-### 6.2 `PlaylistStore` (in `internal/audiobooks/abs/playlists.go`)
-
-```go
-type PlaylistStore interface {
-    ListUserPlaylists(ctx context.Context, userID, profileID string) ([]Playlist, error)
-    GetPlaylist(ctx context.Context, id string) (Playlist, error)
-    CreatePlaylist(ctx context.Context, p Playlist) error
-    UpdatePlaylist(ctx context.Context, p Playlist) error
-    DeletePlaylist(ctx context.Context, id string) error
-    ListPlaylistItems(ctx context.Context, playlistID string) ([]PlaylistItem, error)
-    AddPlaylistItem(ctx context.Context, playlistID, libraryItemID, episodeID string) error
-    RemovePlaylistItem(ctx context.Context, playlistID, libraryItemID, episodeID string) error
-}
-```
-
-### 6.3 Behavior
-
-- **List ordering:** Collections list ordered by `created_at DESC`. Playlists list ordered by `created_at DESC`. Playlist items ordered by `position ASC`. Collection items ordered by `added_at ASC`. All sorting happens in SQL, not in Go.
-- **Empty results:** All List methods return an empty slice (never nil) when no rows match.
-- **`GetCollection` / `GetPlaylist`:** Return `ErrNotFound` when absent. NO owner check — caller authorizes via the response's `UserID` and `IsPublic`.
-- **`AddPlaylistItem` position assignment:** Single SQL statement computing `position = COALESCE(MAX(position), 0) + 1 WHERE playlist_id = $1` inside the INSERT. No read-before-write race.
-- **`AddCollectionItem` / `AddPlaylistItem` idempotency:** `INSERT ... ON CONFLICT (...) DO NOTHING`. Re-adding an existing tuple is a silent no-op (no error, no row mutation, no `updated_at` bump beyond what the handler does separately).
-- **`RemoveCollectionItem` / `RemovePlaylistItem` idempotency:** Return `nil` on no-match.
-- **Profile mapping:** Handlers pass `a.ProfileID` straight through (empty = primary). Store uses `profileArg` helper (returns `nil` for empty, the string otherwise). `COALESCE(profile_id, '00000000-...'::uuid)` in WHERE clauses on both column and bind value, mirroring the BookmarkStore convention.
-- **`updated_at` bump on item mutations:** Both `Add*Item` and `Remove*Item` execute the item mutation and an `UPDATE abs_user_collections SET updated_at = now() WHERE id = $1` (or `abs_playlists`) in the same transaction. Wire field `lastUpdate` reflects this.
-- **Cascade cleanup:** Deleting a collection drops all its `abs_collection_items` via FK CASCADE. Deleting a playlist drops all its `abs_playlist_items`. Deleting a `media_items` row drops it from all `abs_collection_items` (via FK CASCADE); playlists surface stale references on the next List, where the handler degrades to bare-id entries.
-
-### 6.4 Cross-user public read
-
-Handler pattern after `Get*`:
-
-```go
-c, err := store.GetCollection(ctx, id)
-if errors.Is(err, ErrNotFound) || (c.UserID != a.UserID && !c.IsPublic) {
-    http.Error(w, "collection not found", http.StatusNotFound)
-    return
-}
-```
-
-Same pattern for playlists. The condition collapses unknown-id and not-authorized into one branch so existence-leak vectors don't open up.
-
-## 7. Error model
-
-| Condition | Status | Body |
-|---|---|---|
-| Missing/invalid bearer | 401 | handled by `bearerAuth` middleware |
-| Body decode failure (POST/PATCH) | 400 | `invalid body` |
-| Required field missing (POST: `name`; POST item: `libraryItemId`) | 400 | `<field> required` |
-| Unknown collection/playlist on GET (owner or not) | 404 | `collection not found` / `playlist not found` |
-| Non-owner GET on private collection/playlist | 404 | same body — no existence leak |
-| Non-owner PATCH/DELETE/item-mutation | 404 | same body |
-| `library_item_id` not in MediaStore (audiobook add-item) | 404 | `item not found` |
-| Store insert/update/delete fails | 500 | sanitized `<collection\|playlist> persist failed`; err logged via `slog.Error` |
-| List fetch fails after a successful mutation | 200 + best-effort response (in-memory state) + `slog.Warn` | mutation already committed; falling back beats 500 |
-
-### 7.1 Cross-cutting
-
-- **Anti-enumeration.** All non-owner-or-private paths funnel to the same `<type> not found` 404 (never 403, never "private collection"). Indistinguishable from real not-found.
-- **Item validation on add.** `handleAddCollectionBook` and `handleAddPlaylistItem` call `MediaStore.GetAudiobookByID(libraryItemID)` before touching the store. Catches typos and orphan refs early. **Exception:** `handleAddPlaylistItem` with non-empty `episodeId` SKIPS item validation (audiobook-only hydration scope; podcast episodes are stored opaque-id-style).
-- **Body size limit.** All POST/PATCH wrap `r.Body` in `io.LimitReader(r.Body, 1<<20)` before `json.NewDecoder`. Same as bookmarks.
-- **Batch endpoints.** `POST /playlists/{id}/batch/add` and `/batch/remove` tolerate per-item failures silently (matching continuum's `_ = h.store.Add...`). Total failure (e.g., body decode error) is still a 400. Item validation on the batch path: each item validated individually; failed validations skipped with `slog.Debug` (no 404 — the operation as a whole succeeds with the remaining items).
-- **Socket event on batch mutation.** A batch add/remove fires exactly one `playlist_updated` event, regardless of how many items succeeded or failed. Clients re-render from the response.
-- **Socket publish never fails the request.** `h.publish(...)` is nil-safe and fire-and-forget; if the Publisher is unwired the response still completes.

-## 8. Testing
-
-### 8.1 Unit tests — `collections_handler_test.go`
-
-In-memory fake `memCollectionStore` (parallel to `memBookmarkStore`). Reuses `stubMediaStore` and `recordingPublisher` from `bookmarks_handler_test.go`. The `dispatchBookmark` helper is generalized in-place (or a sibling `dispatchABS` is added) so the same wiring (URL params + `ctxAuth` injection) drives both new surfaces.
-
-| Test | Asserts |
-|---|---|
-| `Collection_Create_ReturnsFullShape` | POST `{name:"x"}` → 200, response carries all 7 top-level keys + empty `books[]`, ID is a ULID |
-| `Collection_Create_NameRequired_400` | POST `{description:"only"}` → 400 |
-| `Collection_List_ReturnsWrappedEnvelope` | GET → 200, body is `{"collections":[…]}`, list-shape omits `books` |
-| `Collection_List_DoesNotLeakOtherUsers` | User 1 creates; User 2 GETs → empty list |
-| `Collection_Get_Owner_ReturnsFullShape` | POST → owner GET → 200 + `books[]` |
-| `Collection_Get_NonOwner_Public_OK` | User 1 creates with `isPublic:true`; User 2 GET → 200 |
-| `Collection_Get_NonOwner_Private_404` | User 1 creates (default private); User 2 GET → 404 |
-| `Collection_Patch_OwnerUpdatesNameAndDescription` | POST → PATCH `{name:"y", description:"d"}` → 200, fields updated, `lastUpdate` advanced |
-| `Collection_Patch_NonOwner_404` | User 2 PATCH on User 1's collection → 404 (no existence leak) |
-| `Collection_Delete_OwnerRemovesItAndItems` | POST + add book → DELETE → 204; subsequent GET → 404; items table empty |
-| `Collection_Delete_NonOwner_404` | User 2 DELETE → 404, User 1's collection still present |
-| `Collection_AddBook_Owner_HydratesInResponse` | POST + add book → 200 + `books[]` contains the entry with `media.metadata.title` |
-| `Collection_AddBook_Idempotent` | Add same book twice → 200 both times, `books[]` length stays at 1 |
-| `Collection_AddBook_UnknownItem_404` | Add a non-existent item → 404 `item not found` |
-| `Collection_RemoveBook_Idempotent` | Remove book not in collection → 200, `books[]` unchanged |
-| `Collection_ProfileIsolation` | Profile A creates; Profile B's list returns empty |
-| `Collection_Envelope_HasRequiredKeys` | Marshal-test: 7 top-level keys present even when description and books are empty |
-
-### 8.2 Unit tests — `playlists_handler_test.go`
-
-In-memory fake `memPlaylistStore`.
-
-| Test | Asserts |
-|---|---|
-| `Playlist_Create_ReturnsFullShape` | POST `{name:"x", description:"d", isPublic:true}` → 200, all 8 keys present, ID is ULID |
-| `Playlist_Create_NameRequired_400` | POST `{description:"only"}` → 400 |
-| `Playlist_Create_FiresPlaylistAddedEvent` | POST → `recordingPublisher` captures `playlist_added` with `{id, name}` |
-| `Playlist_List_WrappedEnvelope` | GET → 200, body `{"playlists":[…]}`, list-shape omits `items` |
-| `Playlist_AddItem_AppendsAtNextPosition` | POST + add 3 items → response `items[]` positions are 1,2,3 in insertion order |
-| `Playlist_AddItem_Idempotent` | Add same `(libraryItemId, episodeId)` twice → list length 1 |
-| `Playlist_AddItem_AudiobookHydrates` | Add audiobook item → response item has `title` |
-| `Playlist_AddItem_Episode_AcceptsAndEchoes` | Add `{libraryItemId, episodeId:"ep-1"}` → response item has `episodeId`, no `title` (un-hydrated by design) |
-| `Playlist_AddItem_UnknownAudiobook_404` | Add non-existent audiobook → 404; episode adds skip validation, so episode-only adds succeed |
-| `Playlist_BatchAdd_TolerantOfPartialFailures` | Batch of `[valid, invalid, valid]` → 200, response has 2 items, no 404 |
-| `Playlist_BatchAdd_FiresOneUpdatedEvent` | Batch add → single `playlist_updated` event (not one per item) |
-| `Playlist_BatchRemove` | Seed 3 items, batch-remove 2 → response items[] length 1 |
-| `Playlist_RemoveItem_Single` | DELETE /item/{libraryItemId} → 200, item gone |
-| `Playlist_RemoveItem_WithEpisode` | DELETE /item/{libraryItemId}/{episodeId} → 200, episode-keyed item removed; audiobook-keyed item with same libraryItemId still present |
-| `Playlist_Patch_UpdatesCover` | PATCH `{cover_item:"id"}` → 200, `coverPath` updated; `playlist_updated` event fires |
-| `Playlist_Delete_FiresPlaylistRemovedEvent` | DELETE → 204 + `playlist_removed` event |
-| `Playlist_Get_NonOwner_Public_OK` | User 1 creates `isPublic:true`; User 2 GET → 200 |
-| `Playlist_Get_NonOwner_Private_404` | Private playlist; non-owner GET → 404 |
-| `Playlist_NonOwner_Mutation_404` | User 2 add-item / remove-item / PATCH / DELETE → 404 each, User 1's playlist intact |
-| `Playlist_ProfileIsolation` | Profile A creates; Profile B's list returns empty |
-| `Playlist_Envelope_HasRequiredKeys` | Marshal-test: 8 top-level keys present; `coverPath` omitted when empty |
-
-### 8.3 Shared envelope tests
-
-One marshal test per surface (`collections_envelope_test.go`, `playlists_envelope_test.go`) asserting the wire shape end-to-end. Parallel to `bookmarks_envelope_test.go`.
-
-### 8.4 Live integration smoke (post-deploy, operator)
-
-```bash
-TOKEN=$(curl ... /login | jq -r .accessToken)
-ITEM=$(curl ... /api/libraries/9/items?limit=1 | jq -r .results[0].id)
-
-# Collections
-COLL=$(curl -X POST -d '{"name":"smoke"}' ... /api/collections | jq -r .id)
-curl -X POST ... /api/collections/$COLL/book/$ITEM
-curl ... /api/collections/$COLL                     # books[] contains $ITEM
-curl -X DELETE ... /api/collections/$COLL/book/$ITEM
-curl -X DELETE ... /api/collections/$COLL           # 204
-
-# Playlists
-PL=$(curl -X POST -d '{"name":"queue"}' ... /api/playlists | jq -r .id)
-curl -X POST -d "{\"libraryItemId\":\"$ITEM\"}" ... /api/playlists/$PL/item
-curl ... /api/playlists/$PL                         # items[] contains $ITEM at position 1
-curl -X DELETE ... /api/playlists/$PL/item/$ITEM
-curl -X DELETE ... /api/playlists/$PL               # 204
-```
-
-Expected: each call returns the wire shape from §4; `playlist_added` / `_updated` / `_removed` events appear on the user's Socket.io channel.
-
-### 8.5 Explicitly out of scope
-
-- **No real-Postgres SQL test.** Same posture as bookmarks (§8.4 of that spec): in-memory fakes cover the semantics; CI does not run Postgres for the ABS subdomain.
-- **No episode hydration.** Episode IDs accepted and echoed but not resolved to podcast metadata. A future podcast-playlist sub-project will plug in `podcastfeed` hydration.
-- **No reorder API.** Future follow-up.
-- **No two-user smoke.** Cross-user-public visibility is unit-tested but the operator smoke uses one user.
-
-## 9. Risks & open questions
-
-- **Position gaps after remove.** Removing the middle item from a playlist leaves a `position` gap (1, 3, 4 instead of 1, 2, 3). Clients sort by position; gaps are harmless. If a future reorder API lands, it'll compact positions in a single statement.
-- **Cross-user public + profile scoping interaction.** A public collection owned by `(user A, profile primary)` is visible to user B regardless of B's active profile. The collection's `userId` field discloses A's user identity. Acceptable for v1; if A wanted to hide who owns the collection, that's a separate feature.
-- **No migration rollback test.** Down migrations are `DROP INDEX + DROP TABLE` — low risk, same posture as bookmarks. Not a blocker.
-- **`cover_item` references a `media_items.content_id` but the playlist owner may not have access to that library** — silo's library visibility isn't enforced at the schema level. The cover image hydrator (when added) will need to check visibility. For now, the field round-trips opaquely.
-- **Concurrent `AddPlaylistItem` position collision.** Two parallel appends compute `MAX(position)+1` concurrently and may both produce the same value. The UNIQUE constraint on `(playlist_id, library_item_id, episode_id)` prevents collisions for the SAME item, but distinct items could land at the same position. Acceptable — clients tolerate equal positions and break ties by insertion order. A SERIALIZABLE transaction would close the race; not warranted for a low-traffic UX surface.
-
-## 10. Out-of-scope follow-ups
-
-These are intentionally deferred — they belong to later Phase 1 sub-projects or Phase 2:
-
-- **Smart collections** — sub-project 3 (`abs_smart_collections` + `query_def` JSONB + DSL evaluator).
-- **RSS feeds** — sub-project 4 (`abs_rss_feeds`).
-- **Listening stats** — sub-project 4 (aggregations on `abs_playback_sessions`).
-- **Author / series detail endpoints** — small sub-project, separate.
-- **Continue-listening toggles** — small sub-project, separate.
-- **Reorder API for playlists** — compaction + drag-reorder UX. Probably warrants its own design pass.
-- **Cover-image hydration** — currently the wire emits `coverPath: <content_id>` opaquely. A future enhancement resolves it through `DetailService.PresignURL` to a fully-qualified cover URL.
-- **Episode hydration in playlists** — when the podcast-playlist sub-project lands.
-- **Collection socket events** — Phase 2 of the parent spec.

-# ABS Implementation Fix — Design
-
-**Status:** Approved (brainstorming complete, awaiting writing-plans handoff)
-**Date:** 2026-05-26
-**Scope:** Bring silo-server's Audiobookshelf-compatible API to full parity with the canonical `continuum-plugin-audiobooks` implementation so that official ABS iOS, Android, and 3rd-party (Plappa, AudioBookShelfFully) clients work end-to-end against silo.
-**Out of scope:** silo's native audiobook surface (`/api/v1/audiobooks/*`), silo-android/silo-apple/silo-plugin-sdk repos, Continuum's plugin-host RPC layer, the "standalone listener" port (silo has no separate process), cover transcoding pipelines, transcribed-audio search.
-
-Commands assume the repository root is the cwd.
-
----
-
-## 1. Problem
-
-silo's ABS-compat layer at `internal/audiobooks/abs/` exposes ~20% of the surface that the canonical Continuum plugin implements (`continuum-plugin-audiobooks` reference). Real ABS mobile clients cannot complete the basic flow today — login is reported broken, and even when it succeeds many subsequent calls (filterdata, resume position, author/series IDs) return data shapes that break the client. Bookmarks, collections, playlists, smart collections, RSS feeds, author/series detail, and listening stats are entirely absent. Socket.io publishes only 3 of the ~30 events real clients subscribe to.
-
-The user's directive: every feature of ABS clients must function. Source of truth for behavior is the Continuum plugin; the booklore-ng reference docs (`BOOKLORE_ABS_IMPLEMENTATION_ISSUES.md`, `src/lib/socket/events.ts`) document specific response-shape bugs and the canonical socket event list.
-
-## 2. Goals & Non-goals
-
-### Goals
-- Official ABS iOS app, ABS Android app, and 3rd-party clients (Plappa, AudioBookShelfFully) work end-to-end: add server → login → browse libraries → play → progress sync → bookmark → collection → playlist.
-- Token lifecycle is complete: login, refresh, logout, revocation, multi-device tracking.
-- Socket.io publishes the full event surface real clients subscribe to.
-- New data lives in ABS-scoped tables that don't entangle silo's existing collection system.
-
-### Non-goals
-- silo's native audiobook UI changes.
-- silo-android / silo-apple client changes.
-- Importing real audiobook content via ABS-protocol requests (silo has its own `internal/requests/` system that is not being bridged here).
-- Watch-together, podcast download queues, server-side backup event streams.
-
-## 3. Architecture & Strategy
-
-**Source of truth:** `continuum-plugin-audiobooks` (canonical). Port file-by-file, adapt to silo's data model (catalog repos, `auth.Service`, profile model).
-
-**Topology:** silo is monolithic; the ABS layer reads/writes the local DB directly. The Continuum plugin's `HostClient → backend plugin RPC` layer has no analog and is dropped.
-
-**Package layout:** keep silo's existing `internal/audiobooks/{abs,abssocket,podcastfeed}` — it already mirrors the Continuum plugin's structure.
-
-**Listener:** continue using the dedicated `:13378` ABS-compat HTTP server (configured in `internal/config/db_loader.go` as `audiobookshelf_compat.listen`). Routes mounted on a fresh chi router; no SPA fallback collisions.
-
-**Data isolation:** new ABS surface uses dedicated tables (`abs_bookmarks`, `abs_user_collections`, `abs_collection_items`, `abs_playlists`, `abs_playlist_items`, `abs_smart_collections`, `abs_rss_feeds`). silo's existing `library_collections` / `user_personal_collections` / `user_smart_collections` / collection groups are untouched. Future bridging is possible but out of scope here.
-
-## 4. Phasing
-
-Four phases, each independently mergeable and independently verifiable against a real mobile client.
-
-### Phase 0 — Login + critical bug fixes
-
-**Goal:** iOS/Android app can `add server → login → browse library → tap book → play` end-to-end. No bookmarks/collections/etc. yet.
-
-**Concrete changes:**
-
-| File:line | Change |
-|---|---|
-| `internal/audiobooks/abs/login.go:195-234` | Add to login envelope: `user.itemTagsAccessible: []`, `user.itemTagsSelected: []`, `user.lastSeen: <epoch ms>`, `user.createdAt: <epoch ms>`. Enrich `serverSettings` with `coverAspectRatio`, `dateFormat`, `timeFormat`, `storeCoverWithItem`, `scannerDisableWatcher`, `metadataFileFormat`, `chromecastEnabled`. Mirror Continuum's `completeLogin` (`continuum-plugin-audiobooks/internal/abs/handler.go:591-697`) verbatim. |
-| `internal/audiobooks/abs/login.go:274-315` (`handleABSAuthorize`) | Return the identical envelope as `/login`, including `accessToken` and `refreshToken`. Currently omits them, which breaks resume-on-launch. |
-| `internal/audiobooks/abs/handler.go:353-391` (bearerAuth) | Audit JTI lookup against `abs_session_store.go:GetTokenByJTI` to confirm the freshly-minted JTI is found. Add `slog.Debug` lines at each rejection branch so the next 401 is traceable. Confirm `?token=` query-param fallback parses correctly (iOS AVPlayer requirement). |
-| `internal/audiobooks/abs/libraries_handler.go:499-549` (`siloItemToMetadata`) | Include `id` on every `authors[]` entry (use `item_people.id` UUID). Include `id` on every `series[]` entry (slugified name until a series table lands). Populate `genres` and `tags` from real catalog data instead of empty arrays. Cross-reference `booklore-ng/BOOKLORE_ABS_IMPLEMENTATION_ISSUES.md` lines 9-100. |
-| `internal/audiobooks/abs/play_response.go:119` | Replace hardcoded `currentTime: 0` with `ProgressStore.GetItemProgress(userID, profileID, libraryItemID)` lookup; emit the persisted `currentTime` and `progress` fields. |
-| `internal/audiobooks/abs/libraries_handler.go:56-66` | When `?include=filterdata`, hydrate `authors`, `series`, `narrators`, `genres`, `languages`, `tags` aggregations so iOS filter UI populates. |
-| `internal/audiobooks/abs/login.go` (new handler) | Add `POST /auth/refresh`. Validate refresh token type, check JTI not revoked, mint new access+refresh pair, persist new JTIs. Port from `continuum-plugin-audiobooks/internal/abs/handler.go:handleRefresh`. |
-| `internal/audiobooks/abs/login.go` (new handler) | Add `POST /logout`. Marks caller's JTIs revoked in `abs_sessions`. Port from Continuum's `handleLogout`. |
-| `internal/audiobooks/abs/handler.go:225` (`mountRoutes`) | Mount the new `/auth/refresh` and `/logout` routes (the latter inside `bearerAuth`). |
-
-**Deliverable:** silo build where official ABS iOS app smoke test passes the core flow.
-
-**Size:** ~600-800 lines across ~6 files + 2 new endpoints.
-
-### Phase 1 — Feature surface completion
-
-**Goal:** Bookmarks, manual collections, playlists, smart collections, RSS feeds, author/series detail, and listening stats functional in mobile clients.
-
-**Endpoints to add** (all under `bearerAuth` unless noted; mounted at both `/abs/api/*` and `/api/*`):
-
-**Bookmarks** (port `continuum-plugin-audiobooks/internal/abs/bookmarks_handler.go`)
-- `POST /api/me/item/{itemId}/bookmark` — body `{title, time}` → array of all bookmarks for the item. Fires socket `user_updated` (`reason: "bookmark_created"`).
-- `PATCH /api/me/item/{itemId}/bookmark` — upsert at time position. Fires `user_updated` (`reason: "bookmark_updated"`).
-- `DELETE /api/me/item/{itemId}/bookmark/{time}` — fires `user_updated` (`reason: "bookmark_deleted"`).
-
-**Manual Collections** (port `collections_handler.go`)
-- `GET /api/collections` — list with embedded `libraryItems[]`.
-- `POST /api/collections` — `{name, description}` → single collection.
-- `GET/PATCH/DELETE /api/collections/{id}`.
-- `POST /api/collections/{id}/book/{bookId}` — add item.
-- `DELETE /api/collections/{id}/book/{bookId}` — remove item.
-
-**Playlists** (port `playlists_handler.go`)
-- `GET /api/playlists` → `{playlists: [...]}`.
-- `POST /api/playlists` — `{name, description, cover_item, is_public}`.
-- `GET/PATCH/DELETE /api/playlists/{id}`.
-- `POST /api/playlists/{id}/item` — `{libraryItemId, episodeId?}`.
-- `POST /api/playlists/{id}/batch/add` — `{items: [...]}`.
-- `POST /api/playlists/{id}/batch/remove`.
-- `DELETE /api/playlists/{id}/item/{libraryItemId}[/{episodeId}]`.
-
-**Smart Collections** (port `smart_collection_handler.go` + the entire `internal/smartcoll/` DSL package; adapt SQL to silo's `media_items` schema)
-- `GET /api/me/smart-collections` → `{items: [...]}`.
-- `POST /api/me/smart-collections` — `{name, description, color, is_public, is_pinned, query_def}`.
-- `GET /api/me/smart-collections/{id}`.
-- `GET /api/me/smart-collections/{id}/items` — evaluates `query_def` against the catalog.
-- `PATCH/DELETE /api/me/smart-collections/{id}`.
-
-**Author detail**
-- `GET /api/authors/{id}` — single author with `books[]`.
-- `GET /api/authors/{id}/image` — wire to `item_people.poster_path` via `DetailService.PresignURL` (currently 404s).
-
-**Series detail**
-- `GET /api/series/{id}` — single series with `books[]` sorted by `series_sequence`.
-
-**RSS Feeds** (port `rss_feed_handler.go` + `internal/podcastfeed/`)
-- `POST /api/feeds` — `{itemId, slug, minified}` → `{success, feed: {id, slug, url, ...}}`.
-- `GET /api/feeds` — caller's feeds.
-- `DELETE /api/feeds/{id}`.
-- `GET /abs/public/feed/{slug}` — public RSS XML (no auth, slug is capability token).
-- `GET /abs/public/feed/{slug}/cover`.
-- `GET /abs/public/feed/{slug}/item/{itemId}/{fileIdx}`.
-
-**Listening stats** (port `internal/abs/handler.go:handleListeningStats` + `handleListeningSessions`)
-- `GET /api/me/listening-stats` → `{totalTime, items, days, dayOfWeek, monthly}` from `abs_playback_sessions` aggregation.
-- `GET /api/me/listening-sessions?limit=...` — paginated session history.
-- `GET /api/me/listening-sessions/{sid}` — single session detail.
-
-**Continue-listening toggles** (port `continue_listening.go`)
-- `GET /api/me/progress/{itemId}/remove-from-continue-listening`.
-- `GET /api/me/progress/{itemId}/readd-to-continue-listening`.
-- Adds `hide_from_continue boolean` column to `user_watch_progress` (the table the ABS layer writes via `abs_progress_store.go`).
-
-**Migrations** (numbered after silo's current max, paired up/down per `CLAUDE.md`):
-- `148_abs_bookmarks` — `(id ULID PK, user_id, profile_id, library_item_id, time_seconds, title, created_at, updated_at)` + unique `(user_id, profile_id, library_item_id, time_seconds)`.
-- `149_abs_user_collections` + `150_abs_collection_items`.
-- `151_abs_playlists` + `152_abs_playlist_items`.
-- `153_abs_smart_collections` — includes `query_def jsonb`.
-- `154_abs_rss_feeds` — slug is unique capability token.
-- `155_abs_progress_hide_from_continue` — adds `hide_from_continue boolean default false`.
-
-**Deliverable:** ABS iOS/Android Library, Collections, Playlists, Bookmarks, RSS, Stats tabs all functional.
-
-**Size:** ~3000-4000 lines across ~15 new files + 7 migration pairs. Splittable into 4 sub-commits (bookmarks, collections+playlists, smart collections, RSS+stats).
-
-### Phase 2 — Socket.io full event parity
-
-**Goal:** A logged-in mobile client sees real-time updates when another device on the same account changes progress, when a server scan adds items, when collections/playlists are mutated remotely, and when an admin posts notifications.
-
-**Event surface** (union of Continuum + booklore-ng — what real ABS iOS source subscribes to):
-
-**Server → Client** (~30 events):
-- Lifecycle: `init`, `auth_failed`, `user_online`, `user_offline`, `listener_count`.
-- Progress/session: `user_item_progress_updated`, `user_session_open`, `user_session_updated`, `user_session_closed`, `user_stream_update`, `user_stream_end`.
-- User-scoped: `user_updated` (bookmark reasons).
-- Library: `library_added`, `library_updated`, `library_removed`.
-- Items: `item_added`, `item_updated`, `item_removed`, `items_added`.
-- People/series: `author_added`, `author_updated`, `author_removed`, `series_added`, `series_updated`, `series_removed`.
-- Collections/playlists: `collection_added/updated/removed`, `playlist_added/updated/removed`.
-- RSS: `rss_feed_open`, `rss_feed_closed`.
-- Tasks: `scan_start`, `scan_progress`, `scan_complete`, `task_started`, `task_progress`, `task_finished`.
-- Misc: `notification`.
-
-**Client → Server** (10 events):
-- `auth` (exists), `ping`, `join_library`, `leave_library`, `playback_start`, `playback_sync`, `playback_end`, `stream_open`, `stream_close`, `sync_progress`.
-
-**Architecture changes to `internal/audiobooks/abssocket/`:**
-- Add room types: existing `user:<userID>`, new `lib:<libraryID>` (joined via `join_library`), new `admin:*`.
-- New file `abssocket/publisher.go` exposing `Publisher` interface (`PublishUser`, `PublishLibrary`, `Broadcast`). Replaces ad-hoc `h.publish/h.broadcast` helpers on the Handler struct (currently silent no-ops when `SocketIO == nil`). Tests pass a recording Publisher.
-
-**Cross-package event-source hooks** (via a new `audiobooks.EventBroadcaster` interface in `api.Dependencies` so the consumer packages don't import `abssocket` directly):
-- `internal/scanner/` — emit `scan_*`, `item_*`, `items_added` on audiobook-library scan operations.
-- `internal/taskmanager/` — emit `task_*` for audiobook-scoped tasks.
-- `internal/api/handlers/libraries.go` (or wherever library CRUD lives) — emit `library_*`.
-
-**Auth/lifecycle improvements:**
-- Richer `init` payload: `{userId, connectedAt, libraries[], itemTagsAccessible[]}`.
-- Heartbeat: respond to `ping` with `pong`.
-- On disconnect, decrement listener count and broadcast `user_offline` if this was the user's last device.
-- Reconnect replay (last 30s of user-scoped events) is out of scope for v1; leave a hook.
-
-**Migrations:** none — sockets are stateless except for in-memory connection registry.
-
-**Size:** ~1500-2000 lines: ~600 in `abssocket/`, ~400 publisher wiring across audiobook handlers, ~500 cross-package hooks.
-
-### Phase 3 — Hardening
-
-**Media token signing layer** (port `continuum-plugin-audiobooks/internal/mediatoken/`):
-- Separate HS256 secret (`audiobooks.abs.media_signing_secret`), 15-min TTL, claims bound to `(user_id, profile_id, book_id, file_idx)`.
-- `file_handler.go` mints when building stream URLs; validates on file request.
-- Defense-in-depth: a leaked stream URL grants access to ONE file for 15 minutes instead of full account.
-- Secret stored in `server_settings`, auto-generated on first read.
-
-**Device tracking** (currently `abs_sessions.device_id = JTI`, useless for UI):
-- Parse `User-Agent` on `/login` → derive `device_name`, `client_name`, `client_version`, store on `abs_sessions` insert.
-- `GET /api/me/sessions` — list user's sessions (so they see "iPhone 15 Pro — Sep 1").
-- `DELETE /api/me/sessions/{jti}` — selective revocation.
-
-**Audit log:**
-- New table `abs_audit_log`: `(id, user_id, action, ip, user_agent, metadata jsonb, created_at)`.
-- Logged events: login success/failure, logout, token refresh, session revoke, smart-collection-rule changes.
-- Optional `GET /api/admin/audit-log` for ops visibility.
-
-**Rate limiting beyond login:**
-- Per-user limit on `POST /me/progress` (1/sec — clients sometimes spam this).
-- Per-user limit on `POST /auth/refresh` (5/hour — prevent JTI accumulation).
-
-**Size:** ~800-1200 lines + 2 migration pairs.
-

--- Phase 3: real device tracking
-ALTER TABLE abs_sessions
-  ALTER COLUMN device_id DROP DEFAULT,
-  ADD COLUMN parsed_user_agent text;
-```
-
-## 6. Testing Strategy
-
-**Unit tests** (Go, in-package):
-- Table-driven per handler in `internal/audiobooks/abs/`: happy path, missing field, wrong field type, IDOR (other user's session/bookmark/collection).
-- `abssocket/` `Publisher` recording mock — verify events fire on the right operations with the right payload shape.
-- Smart collection DSL evaluator — port Continuum's `smartcoll_test.go`.
-
-**Integration tests** (against real Postgres + Redis via silo's `internal/audiobooks/testutil` harness):
-- Full login → browse → play → progress → close-session flow.
-- Token refresh — old token rejected, new token accepted.
-- Bookmark CRUD round-trip with socket event capture.
-- Smart collection rule evaluation against seeded catalog.
-
-**End-to-end (manual)**:
-- iOS official ABS app: add server → login → browse → play offline downloads → progress sync across devices.
-- Plappa: same flow. Strictest client for response shape; if Plappa works, everything works.
-- Android official: same.
-
-**Migration safety:**
-- Each migration includes `.down.sql`.
-- New helper `scripts/test-abs-migrations.sh` runs up → down → up against a fresh DB.
-
-## 7. Rollout
-
-Single-shot per phase, no human review gate. **Each phase gets its own implementation plan** (separate `writing-plans` cycle) since a combined plan would be unwieldy at this size. Start with Phase 0; subsequent phases planned only after the prior phase merges and verifies.
-
-| Phase | PR | Verify |
-|---|---|---|
-| Phase 0 | One PR | `make build` → restart silo → curl `/ping` → iOS app smoke test |
-| Phase 1 | One PR (or 4 sub-PRs if reviewable size matters) | iOS app: Bookmarks, Collections, Playlists, Stats tabs functional |
-| Phase 2 | One PR | Two devices on same account: progress sync visible in real time |
-| Phase 3 | One PR | `/api/me/sessions` shows real device names; leaked stream URL expires |
-
-**Cross-repo coordination:** silo-android and silo-apple are NOT touched. The ABS-compat surface targets OFFICIAL ABS clients; silo's own clients use silo's native API.
-
-**Rollback:** every migration has a working `.down.sql`. New tables don't break existing functionality; silo's native audiobook API (`/api/v1/audiobooks/*`) is untouched.
-
-## 8. Open Follow-ups (Explicitly Out of Scope)
-
-- ABS server-side import requests (`/api/me/request`) — Continuum had this; silo has its own `internal/requests/` system. Bridging is a future decision.
-- Podcast episode-download queue events (`episode_download_*`) — only relevant if silo gains podcast download capability beyond RSS refresh.
-- Backup events — silo's backup story is separate.
-- Watch-Together over the ABS socket — silo has `internal/watchtogether/`, deferred.
-- Reconnect replay buffer for socket events — Phase 2 leaves a hook but does not implement.

-## 10. Phase 0 — Status
-
-**Implemented:** 2026-05-26. Plan: `docs/superpowers/plans/2026-05-26-abs-phase-0-login-and-critical-fixes.md`. All 11 plan tasks committed on `feat/audiobooks` and deployed to the production silo container. Endpoint smoke tests confirm correct mount + status codes for `/ping`, `/login`, `/auth/refresh`, `/logout`, `/me`, `/authorize` at both root and `/api`/`/abs/api` prefixes. End-to-end iOS/Plappa app validation pending operator hand-off.

-| 8 | `278f815` | feat(audiobooks): POST /logout for ABS sign-out |
-
-**Tests added:** 15 (6 metadata + 4 resume + 5 refresh + 4 logout — note 4 logout overlaps with refresh's memTokenStore). `go test ./internal/audiobooks/... -count=1` all pass.
-
-**Next:** Phase 1 (bookmarks, collections, playlists, smart collections, RSS, author/series detail, listening stats) will start with its own brainstorming → writing-plans cycle after operator confirms Phase 0 works against real clients.

-# ABS Phase 1 Close-out — Sub-Project 4
-
-**Status:** Approved 2026-05-26. Ready for implementation plan.
-**Scope:** Final sub-project of Phase 1 (per `2026-05-26-abs-implementation-fix-design.md`). Closes out the four remaining feature surfaces in one combined spec/plan to ship in a single push.
-**Predecessor specs:** bookmarks, collections+playlists, smart collections. Established conventions (anti-enumeration 404, `io.LimitReader(1<<20)`, `errors.Is(err, pgx.ErrNoRows)`, profile-scoped + cross-user-public, 200-on-POST, in-package test fakes, `dispatchABSWithParams`) carry over without re-justification.
-
-Commands assume the repository root is the cwd.
-
-## 1. Goal
-
-Land the four remaining Phase 1 surfaces:
-- **Listening stats** — totalTime / days / dayOfWeek / monthly aggregations + paginated session history + per-session detail.
-- **Author detail** — `GET /authors/{id}` and `GET /authors/{id}/image` (the latter currently 404s; wire to people poster image).
-- **Series detail** — `GET /series/{id}` with embedded books sorted by series_sequence.
-- **Continue-listening toggles** — `/me/progress/{itemId}/remove-from-continue-listening` + `/readd-to-continue-listening`, backed by a new `hide_from_continue` column on `user_watch_progress`.
-- **RSS feeds** — minimal viable surface: open a feed for a library item, list caller's feeds, close a feed, and serve the public RSS XML to podcast clients. Series/collection feed variants deferred.
-
-## 2. Non-goals
-
-- **No socket events.** Continue-listening toggles, stats, author/series, and RSS feed mutations fire no events (Phase 2 covers full event parity).
-- **No series/collection RSS feeds.** Only single-item feeds in v1. The continuum `/api/feeds/series/{id}/open` and `/api/feeds/collection/{id}/open` variants are explicitly deferred.
-- **No RSS cover / per-track endpoints.** `GET /feed/{slug}/cover` and `GET /feed/{slug}/item/{itemId}/{idx}` are deferred — podcast clients can fetch covers from the enclosure URL embedded in the RSS XML.
-- **No stable series IDs.** silo stores series denormalised on `audiobook_series.content_id` (one row per book); a "series" is identified by `LOWER(series_name)`. The detail handler accepts URL-decoded series names; URL slugs use the lowercased name. Continuum's stable series-row schema is out of scope.
-- **No author write surface.** Author detail is read-only.
-
-## 3. Architecture
-
-Five surfaces, sharing the established structure. Three new HTTP handler files; one new migration; minimal extensions to existing stores; one new pgx store for RSS.
-
-- **HTTP layer (`internal/audiobooks/abs/`):**
-  - `listening_stats_handler.go` — three handlers (stats / list / detail).
-  - `author_series_handler.go` — three handlers (author / author-image / series).
-  - `continue_listening_handler.go` — two handlers.
-  - `rss_feeds_handler.go` — four authenticated handlers + one public XML handler.
-- **Store extensions:**
-  - `ABSPlaybackSessionStore.AggregateStats(ctx, userID, profileID) (Stats, error)` — single SQL with grouped aggregates.
-  - `ABSPlaybackSessionStore.ListClosedSessions(ctx, userID, profileID, limit, offset) ([]ABSPlaybackSession, int, error)` — paginated history.
-  - `ProgressStore.SetHideFromContinue(ctx, userID, profileID, contentID string, hide bool) error` — toggle column.
-  - `MediaStore.GetAuthorByID(ctx, authorID string) (Author, error)` — author detail + books list.
-  - `MediaStore.GetSeriesByName(ctx, seriesName string) (Series, error)` — series detail + books list ordered by series_index.
-- **New store interface + concrete:**
-  - `RSSFeedStore` interface (CRUD + lookup-by-slug) in `internal/audiobooks/abs/rss_feeds.go`.
-  - `ABSRSSFeedStore` (pgx) in `internal/audiobooks/abs_rss_feed_store.go`.
-- **Migration:**
-  - `154_user_watch_progress_hide_from_continue.up.sql` — `ALTER TABLE user_watch_progress ADD COLUMN hide_from_continue boolean NOT NULL DEFAULT false`.
-  - `155_abs_rss_feeds.up.sql` — feed rows (id, user_id, profile_id, library_item_id, slug, minified, created_at, closed_at).
-- **Service wiring + route registration:** new fields on `abs.Dependencies` + new routes in `mountRoutes` (auth-gated group plus a new unauth public group for `/feed/{slug}.xml`).
-
-## 4. Endpoint surface
-
-All authenticated routes mount under both `/abs/api/*` and `/api/*` inside the existing `bearerAuth` group. Success status is **200 OK** except where the `Returns` column says otherwise.
-
-### 4.1 Listening stats
-
-| Verb | Path | Returns |
-|---|---|---|
-| GET | `/me/listening-stats` | `{totalTime, items, days, dayOfWeek, monthly}` aggregated from `abs_playback_sessions` |
-| GET | `/me/listening-sessions` (?limit=, ?page=) | `pagedEnvelope` of session rows (most-recent-first) |
-| GET | `/me/listening-sessions/{sid}` | single session detail (404 when not found or not owned) |
-
-Stats wire shape:
-
-```json
-{
-  "totalTime": 36000,
-  "items": 12,
-  "days": [{"date": "2026-05-26", "seconds": 1800}, ...],
-  "dayOfWeek": {"0": 1200, "1": 3600, ..., "6": 900},
-  "monthly": [{"month": "2026-05", "seconds": 18000}, ...]
-}
-```
-
-Session row shape:
-
-```json
-{
-  "id": "01HSESS...",
-  "libraryItemId": "126887...",
-  "userId": "1",
-  "startedAt": 1779786284823,
-  "lastUpdate": 1779786884823,
-  "duration": 1500,
-  "currentTime": 1234.5,
-  "timeListening": 600
-}
-```
-
-### 4.2 Author + Series detail
-
-| Verb | Path | Returns |
-|---|---|---|
-| GET | `/authors/{id}` | `{id, name, numBooks, books: [LibraryItem]}` |
-| GET | `/authors/{id}/image` | redirect to PresignURL for `item_people.poster_path` when set; otherwise 404 |
-| GET | `/series/{id}` | `{id, name, numBooks, books: [LibraryItem]}` ordered by series_index ASC |
-
-`{id}` for authors is the stringified `people.id`. `{id}` for series is the URL-decoded series name (case-insensitive lookup). The author-image route was already mounted unauthenticated in handler.go but currently returns 404 — this spec wires the body.
-
-### 4.3 Continue-listening toggles
-
-| Verb | Path | Returns |
-|---|---|---|
-| GET | `/me/progress/{itemId}/remove-from-continue-listening` | 200 `{ok: true}` after setting `hide_from_continue = true` |
-| GET | `/me/progress/{itemId}/readd-to-continue-listening` | 200 `{ok: true}` after setting `hide_from_continue = false` |
-
-Both endpoints are idempotent. Item validation via `MediaStore.GetAudiobookByID` (404 on unknown item). The existing `MediaStore.ListContinueListening` SQL is updated to add `AND uwp.hide_from_continue = false` to the WHERE clause.
-
-### 4.4 RSS feeds
-
-| Verb | Path | Auth | Body | Returns |
-|---|---|---|---|---|
-| GET | `/api/feeds` | bearer | — | `{feeds: [Feed]}` for caller (owner + profile scope, only open feeds) |
-| POST | `/api/feeds/item/{itemId}/open` | bearer | `{slug?, minified?}` | created Feed (full shape) |
-| POST | `/api/feeds/{id}/close` | bearer | — | 204 (sets closed_at) |
-| GET | `/feed/{slug}.xml` | none | — | RSS 2.0 XML; 404 on unknown / closed |
-| GET | `/feed/{slug}` | none | — | same as above (some podcast clients omit the `.xml`) |
-
-Feed wire shape:
-
-```json
-{
-  "id": "01HFEED...",
-  "userId": "1",
-  "libraryItemId": "126887...",
-  "slug": "abc-randomsluggenerated",
-  "minified": false,
-  "createdAt": 1779786284823,
-  "url": "https://silo.example.com/feed/abc-randomsluggenerated.xml"
-}
-```
-
-`slug` is a 16-char URL-safe random string when caller omits it from the body. Manual slugs accepted as long as they match `^[a-z0-9-]{4,64}$`. Slugs are globally unique (UNIQUE index).
-
-RSS XML uses standard RSS 2.0 + iTunes namespace; each `<item>` is one media_file (chapter) of the underlying audiobook. URLs are absolute (`absBaseURL` + `/public/session/...` style — but RSS feeds need a stable public path, so v1 uses a new public file route below). For v1 simplicity, the `<enclosure url>` points at the existing `/abs/public/session/{sid}/track/{idx}` style URL — but feeds don't have an associated session. So we use a new public route mounted in tandem:
-
-**Additional public RSS support route:**
-
-| Verb | Path | Auth | Returns |
-|---|---|---|---|
-| GET | `/feed/{slug}/file/{ino}` | none | streams the media file for the feed's library_item_id (404 if ino doesn't belong to the item) |
-
-This is a feed-scoped public file route — slug is the capability token, so no Bearer needed. Mirrors the bookmarked-session pattern from sub-project 1.

-
-## 6. Storage contracts
-
-```go
-// Extensions to existing interfaces:
-
-// On ABSPlaybackSessionStore (existing):
-AggregateStats(ctx context.Context, userID, profileID string) (Stats, error)
-ListClosedSessions(ctx context.Context, userID, profileID string, limit, offset int) ([]ABSPlaybackSession, int, error)
-
-// On ProgressStore (existing):
-SetHideFromContinue(ctx context.Context, userID, profileID, contentID string, hide bool) error
-
-// On MediaStore (existing):
-GetAuthorByID(ctx context.Context, authorID string) (Author, error)
-GetSeriesByName(ctx context.Context, seriesName string) (Series, error)
-
-// New store interface — RSSFeedStore (defined in internal/audiobooks/abs/rss_feeds.go):
-type RSSFeedStore interface {
-    ListUserFeeds(ctx context.Context, userID, profileID string) ([]RSSFeed, error)
-    GetFeedBySlug(ctx context.Context, slug string) (RSSFeed, error)
-    GetFeed(ctx context.Context, id string) (RSSFeed, error)
-    CreateFeed(ctx context.Context, f RSSFeed) error
-    CloseFeed(ctx context.Context, id string) error
-}
-```
-
-Behavior:
-- `AggregateStats` runs one SQL with three CTE subqueries (days / day_of_week / monthly aggregates) plus a `SUM(time_listening_seconds)` and `COUNT(DISTINCT content_id)`.
-- `SetHideFromContinue` writes `UPDATE user_watch_progress SET hide_from_continue = $4 WHERE user_id = $1 AND profile_id = $2 AND media_item_id = $3`. Returns `nil` even when no row matched (idempotent — no-progress means nothing to hide; client can readd later).
-- `GetAuthorByID` parses `authorID` as int (`strconv.Atoi`), then `SELECT name FROM people WHERE id = $1` for the author row + `SELECT mi.* FROM item_people ip JOIN media_items mi ON mi.content_id = ip.content_id WHERE ip.person_id = $1 AND ip.kind = 7 AND mi.type = 'audiobook' ORDER BY mi.title`. Returns `ErrNotFound` when the people row is missing.
-- `GetSeriesByName` does case-insensitive lookup on `audiobook_series.series_name`: `SELECT DISTINCT series_name FROM audiobook_series WHERE LOWER(series_name) = LOWER($1) LIMIT 1` → name; then `SELECT mi.* FROM audiobook_series s JOIN media_items mi ON mi.content_id = s.content_id WHERE LOWER(s.series_name) = LOWER($1) AND mi.type = 'audiobook' ORDER BY s.series_index NULLS LAST`. Returns `ErrNotFound` when no rows.
-- `RSSFeedStore.CreateFeed` inserts with the slug as-is; UNIQUE constraint on slug surfaces as a 409 client-side. `GetFeedBySlug` only returns rows where `closed_at IS NULL` (closed feeds 404 to podcast clients). `CloseFeed` sets `closed_at = now()` — idempotent on already-closed rows.
-
-## 7. Error model
-
-| Condition | Status | Body |
-|---|---|---|
-| 401 missing/invalid bearer | 401 | bearerAuth |
-| Body decode (POST `/feeds/.../open`) | 400 | `invalid body` |
-| Slug fails `^[a-z0-9-]{4,64}$` | 400 | `invalid slug` |
-| Item not found on author/series/feed POST | 404 | `<type> not found` |
-| Author/Series unknown ID | 404 | `<author\|series> not found` |
-| RSS slug collision on POST | 409 | `slug taken` |
-| Non-owner DELETE/close feed | 404 | `feed not found` (anti-enumeration) |
-| Public `/feed/{slug}` unknown or closed slug | 404 | `feed not found` (plain text body — podcast clients ignore it) |
-| Store mutate fails | 500 | sanitized; err logged |
-
-Cross-cutting:
-- Same `io.LimitReader(1<<20)` on POST/PATCH bodies.
-- Continue-listening toggles are idempotent and return 200 even on no-row-matched.
-- The public RSS routes (`/feed/{slug}.xml`, `/feed/{slug}`, `/feed/{slug}/file/{ino}`) mount OUTSIDE the bearerAuth group — they're capability-gated by the slug. Mount alongside the existing public-session routes in `mountRoutes`.
-
-## 8. Testing
-
-### 8.1 Listening stats
-
-- `TestStats_TotalAggregation` — seed 3 closed sessions, assert `totalTime == sum(time_listening_seconds)` and `items == 2` (3 sessions across 2 distinct items).
-- `TestStats_DayOfWeekBucketing` — sessions on a Monday + a Wednesday + another Monday, assert `dayOfWeek[1] == 2 sessions worth, dayOfWeek[3] == 1`.
-- `TestSessions_List_PaginatedAndScoped` — paged response shape, other-user sessions excluded.
-- `TestSession_Detail_Owner_OK` + `TestSession_Detail_NonOwner_404`.
-
-### 8.2 Author + Series
-
-- `TestAuthor_Detail_ReturnsBooks` — seed author with 2 books; GET returns both, name matches.
-- `TestAuthor_Unknown_404`.
-- `TestAuthor_Image_PresignWired` — when CoverResolver returns a URL, image route 302s; when poster_path is empty, 404.
-- `TestSeries_Detail_OrderedByIndex` — books returned in series_index ASC.
-- `TestSeries_Unknown_404` (name doesn't match any audiobook_series row).
-
-### 8.3 Continue-listening
-
-- `TestContinue_Remove_SetsHideTrue` — seed progress row, GET remove-from-continue, assert column becomes true.
-- `TestContinue_Readd_SetsHideFalse` — inverse.
-- `TestContinue_UnknownItem_404`.
-- `TestContinue_NoProgressRow_OK_Idempotent` — no progress row exists; remove-from-continue still returns 200 (idempotent no-op).
-
-### 8.4 RSS
-
-- `TestFeed_Open_Item_GeneratesSlug` — POST `/api/feeds/item/{id}/open` returns a feed with a random 16-char slug.
-- `TestFeed_Open_AcceptsCustomSlug`.
-- `TestFeed_Open_RejectsInvalidSlug_400`.
-- `TestFeed_Open_RejectsCollision_409`.
-- `TestFeed_List_OwnerOnly` — only caller's open feeds, profile-scoped.
-- `TestFeed_Close_Owner_204`.
-- `TestFeed_Close_NonOwner_404`.
-- `TestPublicFeed_UnknownSlug_404`.
-- `TestPublicFeed_ClosedSlug_404`.
-- `TestPublicFeed_HappyPath_RSSXML` — open a feed with a known item; fetch `/feed/{slug}.xml`; assert Content-Type is `application/rss+xml`, body contains `<rss`, `<channel>`, `<item>`, `<enclosure url=`.
-
-### 8.5 Out of scope
-
-- No real-Postgres SQL test.
-- No live smoke for the public RSS endpoints (operator can hit them; v1 doesn't include the curl snippet).
-- No RSS validator test against a third-party tool.
-
-## 9. References
-
-- Continuum reference: `continuum-plugin-audiobooks/internal/abs/rss_feed_handler.go` (port routing names + slug generation; adapt store/auth to silo).
-- silo's existing public-route precedent: `handlePublicTrack` in `internal/audiobooks/abs/file_handler.go` — same slug-as-capability pattern.
-- Item-people kinds: 7 = author per `media_store.go:ListLibraryAuthors`. Narrator kind not used here.
-
-## 10. Out-of-scope follow-ups
-
-- RSS feed variants: series feeds, collection feeds, cover endpoint, per-track public route is included but is the minimum.
-- Listening-stats `/all-time` vs `/last-N-days` filters — current spec returns a single aggregate.
-- Author edit / merge surface.
-- Series metadata edit.
-- Stats charts beyond the three buckets (per-genre, per-author, per-narrator) — defer.

-# ABS Smart Collections — Phase 1 Sub-Project 3
-
-**Status:** Approved 2026-05-26. Ready for implementation plan.
-**Scope:** Third sub-project of Phase 1 (per `2026-05-26-abs-implementation-fix-design.md`).
-**Predecessor specs:** `2026-05-26-abs-bookmarks-design.md`, `2026-05-26-abs-collections-playlists-design.md`. Conventions established there (anti-enumeration 404, `io.LimitReader(1<<20)` body cap, `errors.Is(err, pgx.ErrNoRows)` store pattern, profile-scoped + cross-user-public read, 200 OK on POST, in-package test fakes + `dispatchABSWithParams`) are reused without re-justification.
-
-Commands in this document assume the repository root is the cwd.
-
-## 1. Goal
-
-Land rule-based "smart" audiobook collections on the silo ABS surface so the official Audiobookshelf clients can define dynamic groupings ("books from 2020-2024 by Brandon Sanderson", "audiobooks I've started but haven't finished", "5-star fantasy under 12 hours"). Rules are stored as a JSON DSL; the items endpoint evaluates the rules against the catalog at request time and returns paginated `LibraryItem` results.
-
-## 2. Non-goals
-
-- **No SQL pushdown.** Evaluation walks the candidate list in Go. silo's audiobook library is small enough (hundreds of items) that linear scan per request is fine. SQL pushdown is a Phase 4 follow-up if the library grows past ~5000 items.
-- **No rule-builder UI.** Clients ship their own; silo just stores and evaluates `query_def`.
-- **No podcast smart collections.** The DSL catalog is audiobook-domain only (title/author/narrator/series/genre/...). Podcast smart collections, if ever needed, get their own DSL.
-- **No socket events.** Matches the manual-collections decision in sub-project 2. Phase 2 covers full event parity.
-- **No saved-search aliases.** A smart collection is fully described by its `query_def`; there's no separate "saved query" entity.
-- **No background materialisation.** Each `/items` call re-evaluates. If perf matters later, add a 30s in-memory result cache keyed on `(collectionID, userID)`.
-
-## 3. Architecture
-
-Three layers, sharing the established silo ABS structure:
-
-- **DSL layer (new package `internal/audiobooks/smartcoll/`):**
-  - `query.go` — `QueryDefinition`, `QueryGroup`, `QueryRule`, `QuerySort` types + field/sort catalogs + `Normalize`/`Validate`/`MarshalJSON`. Ported from continuum's `internal/smartcoll/query.go` verbatim except for the import path.
-  - `evaluator.go` — `Candidate`, `EvaluateOptions`, `Evaluate(ctx, qd, candidates, opts) []Candidate`. Pure function, no I/O. Ported from continuum.
-  - `query_test.go` + `evaluator_test.go` — port continuum's test suites; remove any references to continuum-specific backend types.
-- **HTTP layer (`internal/audiobooks/abs/`):**
-  - `smart_collections_handler.go` — six handlers: `handleListSmartCollections`, `handleCreateSmartCollection`, `handleGetSmartCollection`, `handleSmartCollectionItems`, `handleUpdateSmartCollection`, `handleDeleteSmartCollection`.
-  - `smart_collections_handler_test.go` — in-memory `memSmartCollectionStore` + handler tests reusing `dispatchABSWithParams`, `stubMediaStore`, `recordingPublisher` from prior sub-projects' test files.
-  - `smart_collections_envelope_test.go` — wire-shape marshal test.
-- **Storage layer:**
-  - `internal/audiobooks/abs/smart_collections.go` — `SmartCollectionStore` interface + `SmartCollection` Go model + `smartCollectionToABS` serialiser.
-  - `internal/audiobooks/abs_smart_collection_store.go` — pgx-backed `ABSSmartCollectionStore` (parallel to `abs_collection_store.go`).
-- **Migration:** `153_abs_smart_collections.up.sql` + `.down.sql`.
-- **Bookmark store extension:**
-  - `BookmarkStore.CountByUser(ctx, userID, profileID) (map[string]int, error)` returning `{libraryItemID: count}` for batch hydration of the personalized `bookmark_count` rule. Single SQL: `SELECT library_item_id, COUNT(*) FROM abs_bookmarks WHERE user_id = $1 AND COALESCE(profile_id, sentinel) = COALESCE($2, sentinel) GROUP BY library_item_id`.
-- **Service wiring:** `BuildABSHandler` constructs the new store; field lands on `abs.Dependencies` next to `PlaylistStore`.
-
-## 4. Endpoint surface
-
-All routes mounted under both `/abs/api/*` and `/api/*` inside the existing `bearerAuth` group. Success status is **200 OK** unless the `Returns` column says otherwise.
-
-| Verb | Path | Body | Returns |
-|---|---|---|---|
-| GET | `/me/smart-collections` | — | `{"items": [SmartCollection list-shape]}` |
-| POST | `/me/smart-collections` | `{name, description?, color?, isPublic?, isPinned?, query_def}` | SmartCollection full-shape |
-| GET | `/me/smart-collections/{id}` | — | SmartCollection full-shape when owner OR `isPublic=true`; otherwise 404 |
-| GET | `/me/smart-collections/{id}/items` | (query: `?limit=`, `?page=`) | Paged envelope of `LibraryItem` results from rule evaluation |
-| PATCH | `/me/smart-collections/{id}` | `{name?, description?, color?, isPublic?, isPinned?, query_def?}` | SmartCollection full-shape |
-| DELETE | `/me/smart-collections/{id}` | — | 204 No Content |
-
-### 4.1 Wire shape — SmartCollection
-
-**List-shape and full-shape are identical** (unlike manual collections / playlists where the list-shape omits child items). Smart collections have no stored items; the items are computed by the separate `/items` route. So one shape:
-
-```json
-{
-  "id": "01HSC...",
-  "userId": "1",
-  "name": "Recent Fantasy",
-  "description": "fantasy added in the last 6 months",
-  "color": "#3b82f6",
-  "isPublic": false,
-  "isPinned": true,
-  "queryDef": {
-    "library_ids": [9],
-    "match": "all",
-    "groups": [{
-      "match": "all",
-      "rules": [
-        {"field": "genre", "op": "contains", "value": "Fantasy"},
-        {"field": "added_at", "op": "in_last", "value": "180d"}
-      ]
-    }],
-    "sort": {"field": "added_at", "order": "desc"},
-    "limit": null
-  },
-  "createdAt": 1779786284823,
-  "updatedAt": 1779786284823
-}
-```
-
-All ten top-level keys always present (`description`, `color` default to `""`; `isPublic`, `isPinned` default to `false`; `queryDef` is the parsed JSON, never raw bytes on the wire). Timestamps are JS-epoch milliseconds.
-
-### 4.2 Wire shape — `/items` envelope
-
-Standard ABS paged envelope (`pagedEnvelope` helper already in `handler.go`):
-
-```json
-{
-  "results":  [ /* hydrated LibraryItem objects */ ],
-  "total":    42,
-  "limit":    30,
-  "page":     0,
-  "sortBy":   "added_at",
-  "sortDesc": true,
-  "filterBy": "",
-  "minified": false,
-  "include":  ""
-}
-```
-
-`results` items use the same `siloItemToLibraryItem` shape as `/api/libraries/{id}/items`. Pagination is post-eval slice (eval order is preserved; pages are stable for a given `(collection, user)` as long as the underlying catalog doesn't change).
-
-### 4.3 List-envelope wrap key
-
-Smart-collection LIST uses `{"items": [...]}` — matches continuum's wrap key (which differs from manual collections' `{"collections": [...]}`). Clients pattern-match on the wrap key when distinguishing surfaces; don't override.
-
-## 5. DSL surface (full vocabulary)
-
-### 5.1 Fields (15 total)
-
-**Non-personalized (10):**
-
-| Field | Type | Valid ops | Source |
-|---|---|---|---|
-| `title` | scalar string | `is`, `is_not`, `contains` | `media_items.title` |
-| `author` | array of strings | `is`, `is_not`, `contains` | item people: role=author |
-| `narrator` | array of strings | `is`, `is_not`, `contains` | item people: role=narrator |
-| `series` | array of strings | `is`, `is_not`, `contains` | `audiobook_series` |
-| `genre` | array of strings | `is`, `is_not`, `contains` | `media_items.genres` |
-| `year` | int | `is`, `is_not`, `gt`, `gte`, `lt`, `lte`, `between` | `media_items.release_year` |
-| `rating` | float | `gt`, `gte`, `lt`, `lte`, `between` | `media_items.rating_imdb` (or whichever rating silo populates) |
-| `language` | scalar string | `is`, `is_not` | `media_items.original_language` |
-| `publisher` | scalar string | `is`, `is_not`, `contains` | `media_items.publisher` |
-| `added_at` | timestamp | `gt`, `lt`, `between`, `in_last` | `media_items.added_at` |
-| `duration_seconds` | int | `gt`, `gte`, `lt`, `lte`, `between` | sum of media_files.duration for the item |
-
-**Personalized (5)** — require `AllowPersonalized: true` (only when caller is the collection's owner):
-
-| Field | Valid ops | Source |
-|---|---|---|
-| `finished` | `is` | `user_watch_progress.is_finished` |
-| `in_progress` | `is` | progress exists AND `is_finished == false` AND `current_seconds > 0` |
-| `last_played` | `gt`, `gte`, `lt`, `lte`, `between`, `in_last` | `user_watch_progress.updated_at` |
-| `abandoned` | `is` | `in_progress == true` AND `last_played < now() - 60d` (configurable via `EvaluateOptions.AbandonedAfter`) |
-| `bookmark_count` | `gt`, `gte`, `lt`, `lte`, `between` | count of `abs_bookmarks` rows for (user, profile, item) |
-
-### 5.2 Sort fields
-
-`title` (asc), `added_at` (desc), `year` (desc), `duration_seconds` (desc), `rating` (desc), `random` (deterministic shuffle seeded by `userID + ":" + collectionID`), and personalized: `progress` (desc), `last_played` (desc), `plays` (desc).
-
-### 5.3 Operators
-
-- `is` / `is_not` — equality (case-insensitive for strings; numeric otherwise). For array fields, `is` matches when ANY element equals the value.
-- `contains` — substring (case-insensitive) for scalar strings; element-substring for array fields.
-- `gt` / `gte` / `lt` / `lte` — numeric or timestamp comparison.
-- `between` — `value` is a 2-element array `[low, high]`, inclusive bounds.
-- `in_last` — relative window. `value` is a duration string (`"7d"`, `"180d"`, `"24h"`, `"4w"`). Evaluator parses to `time.Duration`; field must be ≥ `opts.Now - duration`.
-
-### 5.4 Aliases
-
-`authors` → `author`, `narrators` → `narrator`, `genres` → `genre` for fields. `sort_title` → `title`, `recently_added` → `added_at`, `duration` → `duration_seconds` for sorts. Applied in `Normalize()`; older clients with plural / verbose names keep working.
-
-## 6. Data model
-
-### 6.1 Migration 153
-
-`migrations/153_abs_smart_collections.up.sql`:
-
-```sql
-CREATE TABLE IF NOT EXISTS public.abs_smart_collections (
-    id          text PRIMARY KEY,
-    user_id     integer NOT NULL REFERENCES public.users(id) ON DELETE CASCADE,
-    profile_id  uuid,
-    name        text NOT NULL,
-    description text NOT NULL DEFAULT '',
-    color       text NOT NULL DEFAULT '',
-    is_public   boolean NOT NULL DEFAULT false,
-    is_pinned   boolean NOT NULL DEFAULT false,
-    query_def   jsonb NOT NULL DEFAULT '{}'::jsonb,
-    created_at  timestamptz NOT NULL DEFAULT now(),
-    updated_at  timestamptz NOT NULL DEFAULT now()
-);
-
-CREATE INDEX IF NOT EXISTS abs_smart_collections_user_profile_idx
-    ON public.abs_smart_collections (
-        user_id,
-        COALESCE(profile_id, '00000000-0000-0000-0000-000000000000'::uuid)
-    );
-```
-
-`migrations/153_abs_smart_collections.down.sql`:
-
-```sql
-DROP INDEX IF EXISTS public.abs_smart_collections_user_profile_idx;
-DROP TABLE IF EXISTS public.abs_smart_collections;
-```
-
-### 6.2 Schema rationale
-
-- **`query_def jsonb`** — JSONB so future GIN-indexed JSON path probes are an option; default `'{}'::jsonb` so rows with no rules are queryable without NULL guards.
-- **No items table** — smart collections have no stored children; items are computed at eval time.
-- **`color`, `is_pinned`** — UI decorations. silo doesn't validate the color format.
-- **No `library_ids` column** — that list is part of the DSL, lives inside `query_def`.
-
-### 6.3 Go model
-
-```go
-type SmartCollection struct {
-    ID          string
-    UserID      string
-    ProfileID   string
-    Name        string
-    Description string
-    Color       string
-    IsPublic    bool
-    IsPinned    bool
-    QueryDef    []byte    // raw JSONB bytes; decoded on the items path
-    CreatedAt   time.Time
-    UpdatedAt   time.Time
-}
-```
-
-## 7. Storage contract
-
-```go
-type SmartCollectionStore interface {
-    ListUserSmartCollections(ctx context.Context, userID, profileID string) ([]SmartCollection, error)
-    GetSmartCollection(ctx context.Context, id string) (SmartCollection, error)
-    CreateSmartCollection(ctx context.Context, c SmartCollection) error
-    UpdateSmartCollection(ctx context.Context, c SmartCollection) error
-    DeleteSmartCollection(ctx context.Context, id string) error
-}
-```
-
-Behavior follows the established silo pattern: ordered by `created_at DESC`, empty slice never nil, `GetSmartCollection` returns `ErrNotFound` without owner check (handler authorizes), `Update` sets `updated_at = now()`, `Delete` returns nil even on no-match.
-
-**Extension to existing `BookmarkStore`:**
-
-```go
-// CountByUser returns a map of library_item_id → bookmark count for
-// the given (user, profile). Empty map (never nil) when none.
-// Used by the smart-collection items evaluator to hydrate the
-// personalized `bookmark_count` rule in one SQL pass.
-CountByUser(ctx context.Context, userID, profileID string) (map[string]int, error)
-```
-
-SQL: `SELECT library_item_id, COUNT(*) FROM abs_bookmarks WHERE user_id = $1 AND COALESCE(profile_id, sentinel) = COALESCE($2::uuid, sentinel) GROUP BY library_item_id`.
-
-## 8. Items evaluation flow
-
-`handleSmartCollectionItems` runs:
-
-1. Auth + store-nil + URL `{id}` checks (same boilerplate as other handlers).
-2. `GetSmartCollection(ctx, id)` → 404 on ErrNotFound OR `(non-owner AND !isPublic)`.
-3. Decode `c.QueryDef` → `smartcoll.QueryDefinition`. 500 on malformed (shouldn't happen — `Validate` is called on persist; defensive guard).
-4. Resolve target libraries: `qd.LibraryIDs` if non-empty, else every audiobook library from `MediaStore.ListAudiobookLibraries`.
-5. For each target library, fetch the audiobook list via `MediaStore.ListAudiobooks(ctx, libID, 5000, 0)`. (5000 cap matches continuum's; silo's libraries are smaller.)
-6. **Build Candidates.** For each item:
-   - `Candidate.Item` = the `*models.MediaItem`.
-   - If `c.UserID == a.UserID` (owner): hydrate per-user state.
-     - Fetch all progress rows: `ProgressStore.ListProgressForAudiobooks(ctx, a.UserID, a.ProfileID, 10000)`. Build `map[contentID]ProgressRow`.
-     - Fetch bookmark counts: `BookmarkStore.CountByUser(ctx, a.UserID, a.ProfileID)`. Map `contentID → count`.
-     - Populate `IsFinished`, `ProgressPct`, `CurrentSeconds`, `LastPlayedAt`, `BookmarkCount`.
-   - Non-owner viewing public collection: skip hydration; personalized rules eval against zero-values.
-7. `smartcoll.Evaluate(ctx, qd, candidates, EvaluateOptions{AllowPersonalized: c.UserID == a.UserID, UserSeed: a.UserID + ":" + c.ID, Now: time.Now(), AbandonedAfter: 60*24*time.Hour})` → matched + sorted.
-8. Paginate: `limit, page := readPagedQuery(r, 30)`. Override default limit with `qd.Limit` when `?limit=` query param is absent. Slice `matched[page*limit : (page+1)*limit]`.
-9. Hydrate each result via the existing `siloItemToLibraryItem` helper (same as `/api/libraries/{id}/items`).
-10. Wrap in `pagedEnvelope`. Write 200.
-
-### 8.1 Performance budget
-
-- Library fetch: one SQL query per library (~hundreds of rows).
-- Progress hydration: one SQL query for the user's full progress list.
-- Bookmark hydration: one SQL query for the aggregated counts.
-- Total: 2 + N (libraries) queries, all paginated/limited at the store layer. silo's current 1-library config means 3 total queries per `/items` request. Fast enough.
-
-## 9. Error model
-
-| Condition | Status | Body |
-|---|---|---|
-| Missing/invalid bearer | 401 | handled by `bearerAuth` middleware |
-| Body decode failure (POST/PATCH) | 400 | `invalid body` |
-| `name` missing on POST | 400 | `name required` |
-| `query_def` fails `Validate(allowPersonalized=true)` | 400 | `invalid query_def: <reason>` (reason from validator — safe to surface) |
-| Unknown collection on GET (owner or not) | 404 | `smart collection not found` |
-| Non-owner GET on private | 404 | same body — no leak |
-| Non-owner PATCH/DELETE/items | 404 | same body |
-| Store mutate fails | 500 | `smart collection persist failed` (delete: `smart collection delete failed`); err logged via `slog.Error` |
-| `/items` eval — `MediaStore.ListAudiobooks` fails for a library | log `slog.Warn` and skip that library | partial results beat 500 |
-| Personalized rule on non-owner-public eval | silently dropped at `smartcoll.Evaluate` via `AllowPersonalized: false` | no error to the client |
-
-**Cross-cutting:** Body size limit `io.LimitReader(r.Body, 1<<20)` on all POST/PATCH. `validate(allowPersonalized=true)` runs on every persist call; on read, the items handler passes `AllowPersonalized = (c.UserID == a.UserID)` so saved personalized rules are non-fatally dropped when viewed by non-owners.
-
-## 10. Testing
-
-### 10.1 DSL unit tests (`internal/audiobooks/smartcoll/`)
-
-Port continuum's `query_test.go` and `evaluator_test.go` verbatim. The continuum reference covers:
-
-- `Normalize`: aliasing, lowercase, dedupe library_ids, default-match `"all"`, default-sort `"added_at"`.
-- `Validate`: unknown field, invalid op for field, personalized rule without scope, invalid sort field, invalid sort order, negative limit.
-- `Evaluate`: each operator for each field type, AND/OR combinator for groups and definition, personalized rules drop when `AllowPersonalized: false`, `random` sort stability per `UserSeed`, `Limit` honored, empty rules match-everything.
-
-### 10.2 Handler tests (`smart_collections_handler_test.go`)
-
-In-memory `memSmartCollectionStore` (parallel to `memCollectionStore`); reuses `dispatchABSWithParams`, `stubMediaStore`, `recordingPublisher`. The bookmark store extension (`CountByUser`) needs a matching method on `memBookmarkStore` from sub-project 1's test file — extend that fake.
-
-| Test | Asserts |
-|---|---|
-| `SmartCollection_Create_ReturnsFullShape` | POST → 200, 10 top-level keys present, ULID, queryDef round-tripped as a nested object (not raw bytes) |
-| `SmartCollection_Create_NameRequired_400` | empty name → 400 |
-| `SmartCollection_Create_InvalidBody_400` | malformed JSON → 400 |
-| `SmartCollection_Create_InvalidQueryDef_400` | `{"groups":[{"rules":[{"field":"nonsense","op":"is","value":1}]}]}` → 400 with reason in body |
-| `SmartCollection_Create_PersonalizedRuleAllowed` | rule with `field:"finished"` accepted (persist always runs with `allowPersonalized=true`) |
-| `SmartCollection_List_WrappedAsItems` | GET → `{"items": [...]}` envelope key (NOT `"collections"`) |
-| `SmartCollection_List_DoesNotLeakOtherUsers` | user 1 creates; user 2 lists → empty |
-| `SmartCollection_List_ProfileIsolation` | profile A creates; profile B lists same user → empty |
-| `SmartCollection_Get_Owner_ReturnsFullShape` | owner GET → 200 + full-shape |
-| `SmartCollection_Get_NonOwner_Public_OK` | public GET by other user → 200 |
-| `SmartCollection_Get_NonOwner_Private_404` | private GET by other user → 404 (anti-enumeration) |
-| `SmartCollection_Get_Unknown_404` | unknown ID → 404 |
-| `SmartCollection_Patch_Owner_UpdatesFields` | partial PATCH updates only present fields |
-| `SmartCollection_Patch_NonOwner_404` | non-owner PATCH → 404, original untouched |
-| `SmartCollection_Patch_InvalidQueryDef_400` | PATCH with bad query_def → 400 |
-| `SmartCollection_Delete_Owner_204` | DELETE → 204; subsequent GET → 404 |
-| `SmartCollection_Delete_NonOwner_404` | non-owner DELETE → 404, original still present |
-| `SmartCollection_Items_Owner_EvaluatesRules` | seed 3 audiobooks (two match the rule, one doesn't); GET /items returns 2 results |
-| `SmartCollection_Items_PersonalizedDroppedForNonOwner` | public collection with `field:"finished"` rule — non-owner sees ALL matching books (personalized rule silently dropped); owner sees only finished |
-| `SmartCollection_Items_PaginatedEnvelope` | GET /items → standard pagedEnvelope with 9 fields |
-| `SmartCollection_Items_RespectsQueryDefLimit` | qd.Limit=5; GET without ?limit returns 5; GET with ?limit=10 returns 10 (request overrides) |
-| `SmartCollection_Items_NonOwner_Private_404` | private collection /items by non-owner → 404 |
-| `SmartCollection_Envelope_HasRequiredKeys` | marshal-test for 10 top-level keys with empty defaults |
-

-
-### 10.4 Out of scope
-
-- No real-Postgres SQL test (same posture as prior sub-projects).
-- No GIN-index on `query_def`. Phase 4 follow-up if rule-querying becomes a feature.
-- No performance test. Library is small; linear scan is fine.

-- **5000-item per-library cap.** If a library exceeds this, the over-fetch silently truncates. silo's libraries are well below this today; if it changes, switch to paged ListAudiobooks + accumulate.
-- **Personalized rule eval against non-owners is silent.** A non-owner viewing a public collection sees results that don't honor the owner's personalized rules. This is the privacy-correct behavior, but a confused user might wonder why "books I haven't finished" shows everything when viewed by their friend. Document in the parent spec's UX notes.
-- **`random` sort + pagination.** Two requests with the same `(user, collection)` produce the same shuffle (seeded). Browser-back / page-2 stays consistent. If the catalog mutates between requests, the seed still works but new items land in unpredictable positions — acceptable.
-- **`query_def` migration on field-catalog changes.** If silo renames a field or removes an op in the future, existing rows persist the old vocab. `Validate` would reject them, but Normalize won't drop them — we'd surface stale rules as a runtime warning in the items handler. Acceptable for v1.
-- **`description` length.** No cap; relies on the 1 MiB body limit. Same posture as other surfaces.
-
-## 12. Out-of-scope follow-ups
-
-- SQL-pushdown evaluator for large libraries.
-- GIN-indexed JSON path queries on `query_def`.
-- Background materialisation cache for hot smart collections.
-- Cross-collection composition ("collection A + collection B").
-- Result count badges on `/me/smart-collections` (would require running eval on every list call — expensive).
-- Audiobook recommender hooks (the `relevance` sort placeholder in continuum).

-# Unified User Collections (Audiobooks + Movies + TV) Design
-
-**Status:** design — pending implementation plan.
-
-**Source brainstorm:** in-session, 2026-05-27. Driven by audiobook coverage gaps in `page_sections`, `library_collections`, and `user_personal_collections`, plus a parallel `abs_*` collection/playlist/smart-collection stack that doesn't intersect with the silo-canonical tables.
-
-**Commands assume the repository root is the cwd.**
-
----
-
-## 1. Problem
-
-Audiobooks today live in a parallel collections world from movies and TV:
-
-| Surface | Audiobook coverage today |
-|---|---|
-| `page_sections` (homepage rails) | None. Recipes reference only `movie`/`series`. |
-| `library_collections` (admin-owned, library-scoped) | Schema supports `MediaAudiobook` kind but nothing surfaces audiobook-typed admin collections in practice. |
-| `user_personal_collections` (user-owned) | Zero references to audiobooks anywhere in `internal/usercollections/`. |
-| `abs_user_collections` + `abs_collection_items` | Full audiobook-only user-curated collections behind the ABS-compat API. |
-| `abs_smart_collections` | Audiobook-only smart collections with a rule DSL (port of continuum-plugin-audiobooks). |
-| `abs_playlists` + `abs_playlist_items` | Audiobook + podcast-episode ordered playlists. |
-
-Net effect: audiobooks don't appear in any of silo's first-party discovery surfaces, the ABS-app's collection/playlist features don't intersect with silo's native ones, and we maintain two parallel storage stacks.
-
-The data inside the `abs_*` tables today is essentially empty (1 playlist, 0 user collections, 0 smart collections), so unification can land via hard cutover with minimal data migration cost.
-
----
-
-## 2. Goals
-
-- One canonical storage for user-owned lists across all media types.
-- Audiobook items eligible for `page_sections` recipes, `library_collections`, and `user_personal_collections`.
-- ABS-compat endpoints (`/api/collections`, `/api/playlists`, `/api/smart-collections`) continue to work and return identical wire shapes, but their persistence collapses into the canonical store.
-- One smart-collection engine evaluated against all media types.
-- Podcast-episode-level granularity preserved (ABS playlists can name a specific episode within a library item).
-
-## 3. Non-goals
-
-- Admin-curated audiobook collections via the ABS API surface. `library_collections` already supports audiobooks; whether ABS clients should see those admin lists is a separate question deferred for a later design.
-- Frontend changes. Audiobook detail/library pages already exist (per `2026-05-24-audiobook-ui-redesign`) and will consume the unified endpoints when they ship. An admin section-builder media-type selector and any UI surfacing of audiobook sections/collections are follow-up plans.
-- Cross-user shared collections, public sharing, social features. Out of scope.
-- Episode-level granularity for movies/TV. The new `sub_item_id` column is nullable and only populated by podcast playlists.
-
-## 4. Architecture
-
-### 4.1 Storage model
-
-One canonical user-owned-lists table — `user_personal_collections` — extended to discriminate four flavors via `collection_type`:
-
-| `collection_type` | Semantics |
-|---|---|
-| `manual` | Existing. Hand-curated list of items. Order optional. |
-| `synced` | Existing. External sync (Trakt etc.). Items derived from external source. |
-| `playlist` | **New.** Ordered sequence; `position` column on items is meaningful. |
-| `smart` | **New.** Rule-based; items materialized at read time from `query_definition` via `internal/smartcoll/`. |
-
-`user_personal_collection_items` gains one nullable column:
-
-```sql
-ALTER TABLE user_personal_collection_items ADD COLUMN sub_item_id text NOT NULL DEFAULT '';
-```
-
-`sub_item_id` is populated only when the entry refers to a sub-item of a library item (today: podcast episode within a podcast library item). All other entries leave it empty. Audiobook entries always use empty `sub_item_id` because an audiobook is a single `media_items` row.
-
-The CHECK constraint on `collection_type` is widened to admit the new values:
-
-```sql
-ALTER TABLE user_personal_collections
-  DROP CONSTRAINT IF EXISTS user_personal_collections_type_check;
-ALTER TABLE user_personal_collections
-  ADD CONSTRAINT user_personal_collections_type_check
-  CHECK (collection_type IN ('manual', 'synced', 'playlist', 'smart'));
-```
-
-Admin-curated lists (`library_collections`, `library_collection_items`, etc.) are unchanged. They already support audiobooks through the existing `MediaKind` enum.
-
-### 4.2 Smart-collection engine
-
-The current audiobook-only smart-collection engine in `internal/audiobooks/smartcoll/` is promoted to `internal/smartcoll/`:
-
-```
-internal/audiobooks/smartcoll/  →  internal/smartcoll/
-```
-
-Rationale: smart collections are no longer audiobook-only. The DSL operates on `media_items` regardless of type; audiobook-specific rule kinds (e.g. `narrator`, `series_position`) stay registered but evaluate to no-op predicates on non-audiobook items.
-
-The existing simple-shape `query_definition` on `user_personal_collections` (mostly `library_ids` filter) is a strict subset of the smartcoll DSL — existing rows continue to evaluate correctly because their library-id filter maps to the new DSL's library-id predicate.
-
-### 4.3 ABS-compat handler mapping
-
-The three ABS store adapter files in `internal/audiobooks/` get their bodies rewritten to query the canonical tables. Method signatures stay the same so the ABS HTTP handlers above them don't change.
-
-| ABS endpoint | Backing query after cutover |
-|---|---|
-| `GET /api/libraries/{id}/collections` | `SELECT … FROM user_personal_collections WHERE collection_type='manual'` joined to items in this library |
-| `POST /api/collections` | INSERT `user_personal_collections` with `collection_type='manual'`, scoping via `query_definition.library_ids` |
-| `GET /api/libraries/{id}/playlists` | `SELECT … FROM user_personal_collections WHERE collection_type='playlist'` joined to items in this library |
-| `POST /api/playlists` | INSERT `user_personal_collections` with `collection_type='playlist'` |
-| `GET /api/libraries/{id}/smart-collections` | `SELECT … FROM user_personal_collections WHERE collection_type='smart'`; items materialized via `internal/smartcoll` |
-| `episode_id` in playlist items wire shape | maps to `sub_item_id` column |
-
-### 4.4 Page sections (homepage rails)
-
-`page_sections` rows gain a media-types filter. The cleanest carrier is a typed column:
-
-```sql
-ALTER TABLE page_sections
-  ADD COLUMN media_types text[] NOT NULL DEFAULT ARRAY['movie','series'];
-```
-
-Default preserves the current "movies and TV" behavior on existing rows so the migration doesn't change any user-visible rails.
-
-Each recipe declaration in `internal/sections/recipes/` gains a `SupportedMediaTypes` field. Fetchers add `WHERE mi.type = ANY($media_types)` to their queries. Existing recipes set `SupportedMediaTypes = ['movie','series']`; they keep their current behavior. Recipes that work for audiobooks declare `['movie','series','audiobook']` (or `['audiobook']` for audiobook-only ones).
-
-Two new recipes ship at the same time:
-
-- **`continue_listening`** — analog of `continue_watching`; audiobook items with non-zero progress and not finished.
-- **`by_audiobook_series`** — book series rail, drawing from the `audiobook_series` table; mirrors `by_show`.
-
-More audiobook-flavored recipes (top narrators, by genre, new from followed authors) are deferred until the baseline two are exercised.
-
-### 4.5 ABS app contract preservation
-
-Wire-shape compatibility is part of the contract — the ABS Android/iOS apps cannot break. The store-adapter rewrites must produce byte-for-byte identical JSON for the existing endpoints. Concretely:
-
-- IDs remain stable for the moved row(s). The migration preserves `abs_playlists.id` as the new `user_personal_collections.id`.
-- `episode_id` field is emitted from `sub_item_id` (empty string when null/empty).
-- `is_public` field on playlists/smart collections is emitted from `is_shared`.
-- `cover_item` on playlists — needs decision (see §6).
-
-### 4.6 Module structure after the change
-
-```
-internal/
-  smartcoll/                    -- NEW (promoted from audiobooks/smartcoll/)
-    types.go

-```
-
----
-
-## 5. Migration
-
-Single pair: `migrations/156_unify_user_collections.up.sql` / `.down.sql`. Hard cutover.
-
-### 5.1 Up
-
-```sql
--- 1. Extend canonical items table with sub-item granularity.
-ALTER TABLE user_personal_collection_items
-  ADD COLUMN sub_item_id text NOT NULL DEFAULT '';
-
--- 2. Widen the collection_type enum.
-ALTER TABLE user_personal_collections
-  DROP CONSTRAINT IF EXISTS user_personal_collections_type_check;
-ALTER TABLE user_personal_collections
-  ADD CONSTRAINT user_personal_collections_type_check
-  CHECK (collection_type IN ('manual', 'synced', 'playlist', 'smart'));
-
--- 3. Move the single existing abs_playlists row.
-INSERT INTO user_personal_collections
-  (id, user_id, profile_id, name, description, collection_type,
-   is_shared, created_at, updated_at, creator_profile_id)
-SELECT
-  id, user_id, COALESCE(profile_id::text, ''), name, description, 'playlist',
-  is_public, created_at, updated_at, COALESCE(profile_id::text, '')
-FROM abs_playlists;
-
-INSERT INTO user_personal_collection_items
-  (user_id, collection_id, media_item_id, sub_item_id, position, added_at)
-SELECT p.user_id, i.playlist_id, i.library_item_id, i.episode_id, i.position, i.added_at
-FROM abs_playlist_items i
-JOIN abs_playlists p ON p.id = i.playlist_id;
-
--- 4. Drop the abs_* collection tables.
-DROP TABLE abs_playlist_items;
-DROP TABLE abs_playlists;
-DROP TABLE abs_collection_items;
-DROP TABLE abs_user_collections;
-DROP TABLE abs_smart_collections;
-
--- 5. Extend page_sections with media-type filter.
-ALTER TABLE page_sections
-  ADD COLUMN media_types text[] NOT NULL DEFAULT ARRAY['movie','series'];
-```
-
-### 5.2 Down
-
-```sql
--- Reverse the page_sections column.
-ALTER TABLE page_sections DROP COLUMN media_types;
-
--- Recreate the abs_* tables empty by re-applying their CREATE TABLE
--- statements verbatim from the original migration files (no data restored):
---   migrations/149_abs_user_collections.up.sql   → abs_user_collections
---   migrations/150_abs_collection_items.up.sql   → abs_collection_items
---   migrations/151_abs_playlists.up.sql          → abs_playlists
---   migrations/152_abs_playlist_items.up.sql     → abs_playlist_items
---   migrations/153_abs_smart_collections.up.sql  → abs_smart_collections
--- The implementer copies the CREATE TABLE bodies (and indexes) into this
--- down migration; constraint/index names must match the originals so a
--- subsequent up-down-up cycle is idempotent.
-
--- Remove rows we promoted.
-DELETE FROM user_personal_collection_items
-  WHERE collection_id IN (
-    SELECT id FROM user_personal_collections WHERE collection_type IN ('playlist','smart')
-  );
-DELETE FROM user_personal_collections WHERE collection_type IN ('playlist','smart');
-
--- Restore narrow CHECK constraint.
-ALTER TABLE user_personal_collections
-  DROP CONSTRAINT IF EXISTS user_personal_collections_type_check;
-ALTER TABLE user_personal_collections
-  ADD CONSTRAINT user_personal_collections_type_check
-  CHECK (collection_type IN ('manual', 'synced'));
-
--- Drop the sub_item_id column.
-ALTER TABLE user_personal_collection_items DROP COLUMN sub_item_id;
-```
-
-The down migration is symmetrically structured but lossy in reverse: rolling back loses any playlist/smart rows created after the cutover. That's acceptable because the abs_* tables were near-empty before the up.
-
-### 5.3 Risk
-
-| Risk | Probability | Mitigation |
-|---|---|---|
-| Down-migration loses real user data | Low (one row today; grows over time) | Snapshot the table before running down in any prod context |
-| ABS app sees wire-shape regressions | Medium | Snapshot tests on JSON output of each ABS endpoint before/after |
-| smartcoll DSL gap (silo-native query_definition row that doesn't fit DSL subset) | Low | Pre-migration query enumerates non-conforming rows; spec asserts subset compat |
-| `library_collections` UI gains audiobook rows it can't render | Low | UI changes deferred; admin doesn't currently create audiobook-typed library collections |
-
----
-
-## 6. Open questions
-
-1. **Playlist `cover_item` field.** `abs_playlists.cover_item` is a FK to `media_items.content_id`. `user_personal_collections.poster_url` is a plain text URL. Two options for the migration: (a) drop `cover_item`, regenerate poster URLs from the first item in the playlist; or (b) add a `cover_content_id` column to `user_personal_collections`. Recommend (a) for simplicity — the existing playlist row has no `cover_item` set.
-
-2. **`is_pinned` on smart collections.** `abs_smart_collections.is_pinned` has no analog in `user_personal_collections`. Likely needs a new boolean column; defer until smart-collection UI work names a use case.
-
-3. **`color` on smart collections.** `abs_smart_collections.color` has no analog. Same call as `is_pinned` — defer; the existing 0 rows means no data to preserve.
-
-4. **Admin-curated audiobook collections in the ABS API.** Out of scope per §3, but flagged for a future design.
-
----
-
-## 7. Testing
-
-- **Migration round-trip test.** Run `up.sql` → `down.sql` → `up.sql` on a fresh test DB seeded with one of each `abs_*` row. Assert canonical-table contents are identical before and after.
-- **ABS endpoint wire-shape snapshots.** Generate JSON for `GET /api/libraries/{id}/collections|playlists|smart-collections` before the cutover; assert byte-equal after.
-- **smartcoll engine portability.** Move the existing `internal/audiobooks/smartcoll/*_test.go` into `internal/smartcoll/` and add three new tests:
-  - audiobook-specific rule (`narrator` filter) evaluated against an audiobook → expected items.
-  - audiobook-specific rule evaluated against a movie → empty set (no-op predicate).
-  - simple library-id filter (silo-native query_definition shape) evaluated under the unified DSL → expected items.
-- **Section recipe regression.** Existing recipes with default `media_types=['movie','series']` return identical results to today. New `continue_listening` and `by_audiobook_series` recipes covered with focused unit tests.
-
----
-
-## 8. Sub-projects
-
-This design is decomposed for implementation:
-
-1. **Schema migration + canonical storage extensions** — migration 156, CHECK/column additions, no behavior changes yet.
-2. **Smart-collection engine lift** — move `internal/audiobooks/smartcoll/` to `internal/smartcoll/`, update imports, no logic changes.
-3. **ABS store adapter rewrites** — collection/playlist/smart-collection stores query canonical tables.
-4. **Section recipes for audiobooks** — recipe `SupportedMediaTypes` field, two new recipes, fetcher type filter.
-5. **Documentation + follow-up tickets** — open-question call-outs (cover_item, is_pinned, color, admin collections in ABS).
-
-Each sub-project has a single-MR scope and ships independently of the others. Sub-project 1 lands first; sub-projects 2–4 can land in any order after it.

+# Resilient Library Deletion Design
+
+## Goal
+
+Make `delete_library` survive concurrent database writers and large libraries. Today it deletes an entire library inside a single multi-minute transaction; on a large library this deadlocks against ordinary background writes and rolls back, making zero progress. Rewrite the deletion to run in small, autocommitted batches with per-batch deadlock retry, so it completes reliably, holds only short locks, and resumes cleanly if interrupted.
+
+## Background
+
+A `delete_library` admin job repeatedly failed with:
+
+```
+deleting orphaned items: ERROR: deadlock detected (SQLSTATE 40P01)
+```
+
+Diagnosis on a library of ~249K items / ~339K media files:
+
+- The whole deletion runs in one transaction in `FolderRepository.DeleteWithStats` (`internal/catalog/folder_repo.go`): collect orphan IDs, drop the folder (CASCADE), then `DELETE FROM media_items WHERE content_id = ANY($1)`.
+- `media_items` cascades to 15 child tables, so a bulk delete holds a very large lock set for minutes.
+- The Postgres deadlock log shows the cycle: the delete cascade into `media_item_provider_ids` versus a concurrent `INSERT INTO media_item_provider_ids` from a routine background task. Each ~7-minute attempt was guaranteed to overlap an ordinary write and lose.
+- Because it is one transaction, every failure rolls back completely: no progress, not resumable.
+
+The fix targets the deletion mechanism only. Coordinating or pausing background writers is explicitly out of scope (see Out of Scope) — a batched, retrying delete is robust against *any* concurrent writer, not just today's tasks.
+
+## Approach
+
+Replace the single transaction with a sequence of phases. Each phase deletes in bounded batches, and each batch is one autocommit statement wrapped in a deadlock-retry helper. Short lock windows make deadlocks rare; when one occurs, only that small batch retries.
+
+Scope of the rewrite:
+
+- Rewrite `FolderRepository.DeleteWithStats` in `internal/catalog/folder_repo.go`.
+- Add an unexported `retryOnDeadlock` helper in the `catalog` package.
+- `FolderRepository.Delete` (thin wrapper), the `DeleteFolderStats` struct, and the `delete_library` executor in `internal/adminjob/library_delete.go` keep their current signatures and behavior. S3 image-cleanup queueing and generated-home-section cleanup are untouched.
+
+## Deletion phases
+
+`DeleteWithStats(ctx, id, progress)` performs, in order:
+
+### Phase 0 — preflight (reads only)
+
+- Load the folder name; return `ErrFolderNotFound` if the row is gone.
+- `COUNT` media files (`WHERE media_folder_id = $1`), item links (`WHERE media_folder_id = $1`), and orphans, to populate the result payload and the progress denominator.
+
+### Phase 1 — orphaned `media_items` (batched loop)
+
+Repeat until no rows are returned:
+
+```sql
+SELECT mil.content_id
+FROM media_item_libraries mil
+WHERE mil.media_folder_id = $1
+  AND NOT EXISTS (
+    SELECT 1 FROM media_item_libraries other
+    WHERE other.content_id = mil.content_id
+      AND other.media_folder_id <> $1
+  )
+LIMIT $2          -- orphanDeleteBatch
+```
+
+For each returned batch: collect S3 image dirs for those IDs (existing `collectImageDirs`, accumulated into a deduped set), then
+
+```sql
+DELETE FROM media_items WHERE content_id = ANY($1)
+```
+
+The FK cascade removes each item's `media_item_libraries` (including this folder's), `media_item_provider_ids`, episodes, seasons, embeddings, and the rest of the 15 child tables. Deleting orphan items first also clears their junction rows, so the next iteration's detection query naturally advances. Orphan detection must run before Phase 3 touches shared junctions, so the "only in this folder" test stays valid.
+
+### Phase 2 — folder `media_files` (batched loop)
+
+`media_files` is folder-tied (`media_folder_id` FK, `ON DELETE CASCADE`), not item-tied, so it is deleted by folder. Repeat until a batch deletes fewer than the batch size:
+
+```sql
+DELETE FROM media_files
+WHERE id IN (
+  SELECT id FROM media_files WHERE media_folder_id = $1 LIMIT $2  -- folderChildDeleteBatch
+)
+```
+
+### Phase 3 — remaining shared-item junctions (batched loop)
+
+After Phase 1, the only `media_item_libraries` rows left for this folder belong to items that also live in other folders. Delete them in batches (dropping the membership only, never the shared item):
+
+```sql
+DELETE FROM media_item_libraries
+WHERE ctid IN (
+  SELECT ctid FROM media_item_libraries WHERE media_folder_id = $1 LIMIT $2  -- folderChildDeleteBatch
+)
+```
+
+### Phase 4 — folder row
+
+```sql
+DELETE FROM media_folders WHERE id = $1
+```
+
+Now lightweight. Tolerates 0 rows affected (a resumed re-run may already have removed it) — it does not re-raise `ErrFolderNotFound` here. The folder row is deleted **last**, so a partial deletion leaves the library present-but-disabled and a re-run continues.
+
+## Deadlock-retry helper
+
+New unexported helper in the `catalog` package:
+
+```go
+func retryOnDeadlock(ctx context.Context, op func() error) error
+```
+
+- Retries when the error is a `*pgconn.PgError` with code `40P01` (deadlock) or `40001` (serialization failure).
+- Up to 5 attempts, exponential backoff starting at 50ms, doubling each retry.
+- Honors `ctx` cancellation between attempts (returns `ctx.Err()`).
+- Any non-retryable error returns immediately; the final retryable error is returned after the cap.
+
+Every batch statement runs through `retryOnDeadlock`. It has a single caller today, so it stays package-local; it can be promoted to a shared DB utility if a second caller appears.
+
+## Batch sizes
+
+Named constants in `internal/catalog/folder_repo.go`, tunable:
+
+- `orphanDeleteBatch = 1000` — small, because each `media_items` row cascades across 15 tables.
+- `folderChildDeleteBatch = 5000` — for the lighter folder-scoped `media_files` and junction deletes.
+
+## Transaction model, stats, progress
+
+- No surrounding transaction. Each batch is a single `pool.Exec` (its own implicit transaction), mirroring the existing batched-cleanup pattern in `internal/opslog/cleanup.go`. This is the core change that eliminates the multi-minute lock window.
+- Stats: `MediaFiles` and `MediaItemLinks` come from the Phase 0 counts; `OrphanedItems` accumulates across Phase 1 batches; `OrphanedImageDirs` is the accumulated deduped dir set. Image-dir volume for the affected workloads is modest; the deduped set is the bounded-memory point of note.
+- Progress: the callback reports orphan items processed against the Phase 0 orphan total, plus phase-transition messages. The admin-job runner's existing 10s heartbeat keeps the job alive across the drain.
+
+## Error handling & resumability
+
+- Because batches autocommit, a failure or cancellation persists partial progress. There is no rollback of hundreds of thousands of rows and no long lock hold.
+- The job is resumable by re-running it: the folder still exists (deleted last), and Phase 1 re-detects whatever orphans remain.
+- New items inserted concurrently during deletion are picked up by the loop's re-detection.
+
+## Testing
+
+The `catalog` package uses pure-Go unit tests; there is no Postgres integration harness, so tests avoid a live database.
+
+- **`retryOnDeadlock` unit test:** a fake `op` returns a `*pgconn.PgError{Code: "40P01"}` N times then `nil` — assert it retries, respects the attempt cap, backs off, and returns immediately on a non-retryable error; a separate case asserts `ctx` cancellation stops retries.
+- **Batch-loop unit test:** extract the "loop until a batch is under the batch size" iteration behind a small injected exec function so the looping/chunking logic is testable without Postgres.
+- **Integration verification on dev:** deploy and re-trigger the deletion against the real stuck library; confirm it drains to completion via application logs and database row counts. This is the integration test, given the absence of a catalog DB harness. (Commands assume the repository root is the cwd and follow the deployment-debugging runbook.)
+
+## Out of scope
+
+- Pausing or coordinating background writers (e.g., having metadata/scan tasks skip disabled or pending-deletion libraries). The batched, retrying delete is robust against any concurrent writer; writer coordination is a separate potential improvement.
+- Changing the admin-job runner, the executor's image-cleanup queueing, or home-section cleanup.
+- Schema or FK changes.

+- **Scope:** `silo-server` (Go backend + web admin UI). Client follow-ups in `silo-android` / `silo-apple` are additive and optional.
+- **Note:** All paths are repository-relative. Commands assume the repository root is the cwd.
+
+## Problem
+
+The calendar works but is not practical. It defaults to *every* upcoming airing in the catalog, so it is noisy and undifferentiated — the user has to mentally filter out shows they don't care about. We want a Simkl-style preset switcher with a personalized default, powered by the server's real watch data rather than a manually curated list.
+
+## Goals
+
+- Default the calendar to a personalized **Following** view (shows the profile actually engages with).
+- Offer a small set of presets, including a **server-wide** popularity view and an **external trending** view.
+- Keep it cheap under load (hundreds of concurrent users): presets must **filter, not compute**.
+- Make "what do I still need to watch this week" visible via a watched overlay.
+- Preserve backward compatibility for existing clients.
+
+## Non-Goals
+
+- No cross-user caching of the windowed airing query yet (phased — add only if metrics show strain).
+- No pulling in external content that isn't in the library (e.g. a followed show whose next season hasn't been added). The calendar stays catalog-scoped.
+- No change to the week-view layout, timezone handling, or event ordering (recently tuned; left intact).
+- No region/country or "For Kids" presets (considered and cut).
+
+## Presets
+
+The selector replaces today's `All / Favorites / Watchlist` toggles.
+
+| Preset | Shows | Source |
+|---|---|---|
+| **Following** *(default)* | Upcoming airings for series the profile has watched, favorited, or watchlisted | per-profile: `user_favorites` ∪ `user_watchlist` ∪ watched-series rollup |
+| **Popular here** | Airings for what is most-watched server-wide | cached `recommendation_cache` (`RecTypePopular`, global key) |
+| **Trending** | Airings for externally-trending shows that exist in the library | `trending_discover_snapshots` |
+| **Everything** | All catalog airings (today's behavior) | no restriction |
+
+Per-profile vs server-wide is split cleanly across two presets: **Following** is personal (this profile), **Popular here** is the server-wide aggregate.
+
+## Core principle: filter, don't compute
+
+Every preset resolves to **the windowed airing candidate list ∩ a small id-set**. No preset triggers a fresh aggregation at request time.
+
+1. **Step 1 — windowed candidate fetch** (unchanged from today): the 3-branch UNION in `internal/catalog/calendar_repo.go` over movies/episodes/season-premieres, scoped only by library access + content rating, across the ±2-day-padded window. Its result depends only on the access signature, not on viewer identity, so it remains cacheable across users later.
+2. **Step 2 — intersect with one id-set**, chosen by preset:
+   - **Following** → resolve the profile's followed id-set once per request, then filter `itemIDExpr = ANY($set)`.
+   - **Popular / Trending** → read the already-cached global id-set and intersect.
+   - **Everything** → no restriction.
+3. **Step 3 — group by day, sort by viewer-local wall-clock time, respond** (unchanged).
+
+The only heavy SQL is Step 1, which already runs today for every calendar load. Presets add a bounded id-set intersection, never a new aggregation.
+
+### Unify the filter mechanism
+
+All personal/preset filters resolve to "an id-set, then `itemIDExpr = ANY($set)`". This replaces the special-cased favorites/watchlist `EXISTS` subqueries in `appendPersonalFilterClause` with a single code path (favorites and watchlist become id-sets resolved from their tables — they are subsets of Following). One mechanism is easier to reason about and removes duplicated clause-building.
+
+`itemIDExpr` continues to be `mi.content_id` for movies and `e.series_id` / `s.series_id` for episodes / season premieres, so a watched/favorited **movie** matches by its own content_id while a followed **series** matches by series id.
+
+### Following id-set
+
+Resolved per request as the DISTINCT union of:
+
+- `SELECT media_item_id FROM user_favorites WHERE user_id = $u AND profile_id = $p`
+- `SELECT media_item_id FROM user_watchlist WHERE user_id = $u AND profile_id = $p`
+- `SELECT DISTINCT COALESCE(e.series_id, wp.media_item_id) FROM user_watch_progress wp LEFT JOIN episodes e ON e.content_id = wp.media_item_id WHERE wp.user_id = $u AND wp.profile_id = $p`
+
+"Engaged" = the presence of a `user_watch_progress` row (you've started it); no completion threshold required for Following. The rollup mirrors the established pattern in `GetPopularItems` (`internal/recommendations/repo.go`) — reuse that rollup expression rather than duplicate it.
+
+The candidate list (Step 1) is small (one week of airings), so intersecting against a bounded array is cheap. Caveat: a pathologically large followed-set (a profile that has watched thousands of distinct series) makes the array large; if that ever shows up as hot, switch the Following preset to correlated `EXISTS` against the user's tables. Not building that now.
+
+### Popular / Trending id-sets
+
+- **Popular**: `GetRecommendationCache(ctx, GlobalCacheUserID, GlobalCacheProfileID, RecTypePopular, "")` → `[]ScoredItem`; use `MediaItemID` values (already series-level via the `GetPopularItems` rollup). Refreshed by the recommendations worker on a TTL; readers never aggregate live.
+- **Trending**: `TrendingSnapshotRepository.Get(ctx, source, window)` → `TrendingSnapshot.ContentIDs` (pre-resolved to catalog content_ids, viewer-agnostic). The calendar reads the canonical default snapshot (`tmdb` / `week`). Unioning multiple sources/windows is possible but out of scope.
+
+**Access is preserved automatically:** Popular/Trending id-sets are viewer-agnostic and may include items a given profile cannot access. Because we intersect them with the access-scoped Step-1 candidates (library scoping + `MaxContentRating` already applied there), inaccessible items drop out naturally. No extra access check needed on the id-sets.
+
+**Cold/empty cache:** if the Popular cache or Trending snapshot is empty (fresh server, worker hasn't run, provider unconfigured), the id-set is empty and the preset returns no rows. This must render the empty state, not an error.
+
+## Watched overlay
+
+After Step 1, decorate the windowed events with per-profile watched status:
+
+- One bounded lookup: `SELECT media_item_id FROM user_watch_progress WHERE user_id = $u AND profile_id = $p AND completed = true AND media_item_id = ANY($episodeContentIds)` over the window's episode/movie content_ids.
+- Watched items render dimmed + ✓. This is a per-profile overlay applied after Step 1 (like the Following filter), so it does not affect the shareability of the Step-1 candidate set.
+- Premiere / finale / new-season badges extend the existing `buildBadges` logic in `internal/api/handlers/calendar.go`.
+
+## UI / UX
+
+- **Selector** (`web/src/pages/Calendar.tsx`): segmented pills on desktop, collapsing to a dropdown on narrow viewports — the same responsive swap the week navigator already uses. The library picker stays beside it. Both presentations bind to one selected-preset state.
+- **Empty state**: when **Following** has no upcoming airings (new or sparse profile), show a nudge with quick switches to Popular / Trending / Everything instead of a blank week.
+- **Persistence**: remember the profile's last-chosen preset in `localStorage` (keyed by profile id) so the calendar reopens where the user left it. Server-side profile preference is a possible future enhancement.
+- **Card cues** (`web/src/components/calendar/CalendarEventCard.tsx`, `web/src/lib/upcomingEventPresentation.ts`): badges + watched overlay as above.
+
+## API contract
+
+- Extend `/calendar`'s `filter` parameter to accept `following | popular | trending | everything`.
+- **Keep `all | favorites | watchlist` valid** so existing `silo-android` / `silo-apple` clients keep working unchanged. `all` and `everything` are equivalent. This is purely additive.
+- Add an additive `watched: bool` field (and any new badge string) to each event item. Older clients ignore unknown fields.
+- Default when `filter` is omitted: today it is `all`. The **web client** will request `following` explicitly; the server default stays `all` to avoid changing behavior for existing API consumers. (Default-view personalization is a client choice, not a server-contract change.)
+- **Profile requirement:** the `/calendar` route already runs behind `RequireProfile`, so a profile is always present. `following` (and legacy `favorites` / `watchlist`) plus the watched overlay are per-profile and resolve against it; `popular` / `trending` / `everything` / `all` are profile-agnostic and ignore it.
+
+### Multi-repo coordination (per CLAUDE.md)
+
+- `silo-android` / `silo-apple`: may adopt the new presets and the watched cue as independent follow-ups. Nothing here forces a lockstep change because old filter values and response shape remain valid.
+
+## Implementation surface
+
+Backend:
+- `internal/catalog/calendar_repo.go` — add an id-set restriction to `CalendarFilter`; generalize `appendPersonalFilterClause` into a single `ANY($set)` path; keep library/rating clauses intact.
+- A followed-id-set resolver, `ListFollowedSeriesIDs(ctx, userID, profileID)`, placed in the package that owns the favorites/watchlist/episode join; reuse the `GetPopularItems` rollup expression.
+- `internal/api/handlers/calendar.go` — validate the expanded `filter` set; orchestrate preset → id-set resolution (Following resolver, Popular cache read, Trending snapshot read); apply the watched overlay; extend `buildBadges`.
+
+Frontend:
+- `web/src/pages/Calendar.tsx` — responsive selector + preset persistence + empty state.
+- `web/src/hooks/queries/calendar.ts` — new `filter` values; `watched` field on the event type.
+- `web/src/components/calendar/CalendarEventCard.tsx` — watched overlay + badge rendering.
+- `web/src/lib/upcomingEventPresentation.ts` — badge/treatment helpers.
+
+## Edge cases
+
+- Cold/empty Popular cache or Trending snapshot → empty preset → empty state, never an error.
+- Profile with no follows → Following empty → empty state with preset nudges.
+- Large followed-set → bounded array today; correlated-`EXISTS` fallback noted for later.
+- Movie vs episode/season id matching (`content_id` vs `series_id`) handled by the existing `itemIDExpr` selection per branch.
+- Specials (`season_number = 0`) remain excluded.
+- Access control (`MaxContentRating`, library scoping, disabled libraries) still enforced for every preset via Step 1; viewer-agnostic id-sets cannot leak inaccessible items because of the intersection.
+- Backward-compat filter values (`all | favorites | watchlist`) still resolve through the unified id-set path with identical results.
+
+## Testing strategy
+
+- **Repo** (`internal/catalog/calendar_repo_test.go`): each preset's id-set filter (following / popular / trending / everything), empty id-set → zero rows, access + rating enforcement preserved across presets, movie-by-content_id vs series-by-series_id matching, legacy favorites/watchlist parity.
+- **Handler** (`internal/api/handlers/calendar_test.go`): filter validation accepts new + legacy values; Popular/Trending cold cache degrades to empty gracefully; `watched` field populated correctly; watched lookup bounded to the window.
+- **Frontend**: selector responsive swap (pills ↔ dropdown), preset persistence across reloads, watched overlay + badge rendering, Following empty state.
+
+## Future work
+
+- Cross-user cache of the Step-1 windowed candidate set keyed by (window, access-signature), if load metrics justify it.
+- External enrichment of followed shows whose next season is not yet in the library.
+- Server-side persisted preset preference per profile.
+- Optional union of multiple Trending sources/windows.

+# Trending Discover — Persistent Snapshot Design
+
+Status: Approved (design)
+Date: 2026-05-29
+
+Commands assume the repository root is the cwd.
+
+## Problem
+
+The `trending_discover` home section pulls global trending (TMDB or Trakt),
+matches it to titles in the viewer's libraries, and renders the result. Today
+the external fetch + external-ID resolution are memoised in an **in-process
+map** (`editorialCandidateCache`) keyed by `source|window|fetchLimit` with a
+1-hour TTL and a `singleflight` group to collapse concurrent misses
+(`internal/sections/fetcher.go`, `loadTrendingDiscoverContentIDs`).
+
+That cache has three weaknesses, two of which we explicitly want to fix:
+
+1. **No resilience to upstream failure.** At TTL expiry a request still blocks
+   on the TMDB/Trakt call, and a slow or down provider degrades the home page.
+   There is no concept of "serve the last good list."
+2. **No observability.** Nothing records when trending last refreshed, whether
+   it succeeded, or how many trending titles matched the catalog.
+3. (Secondary) It is per-process and volatile — lost on restart, and each
+   server instance fetches independently.
+
+## Goals
+
+- Reads of the trending section **never call the upstream provider** and never
+  block on it. They serve a persisted, last-good list.
+- A persisted, inspectable record with refresh history (the same "synced
+  record" shape used by library collections).
+
+## Non-goals
+
+- Reusing the library-collection machinery. `library_collections.library_id` is
+  `NOT NULL` (collections are library-scoped); trending is deliberately
+  library-agnostic and appears once. Making collections library-agnostic is a
+  large, separate change and is out of scope.
+- An admin UI for the snapshot. The persisted columns make this possible later,
+  but it is not part of this work.
+- A shared/distributed cache (Redis). The DB is the single source of truth.
+
+## Approach
+
+Replace the lazy in-process cache with a **background-refreshed persistent
+snapshot**. A scheduled task refreshes the trending list on an interval; the
+read path only ever reads the persisted snapshot. This mirrors the
+collection-sync *pattern* (`CollectionSyncScheduler` + `SyncCollectionsTask`)
+without reusing its library-scoped storage.
+
+The change cleanly separates **read** from **refresh**:
+
+- The refresh path owns the upstream call and external-ID resolution.
+- The read path owns only a primary-key snapshot lookup plus the existing
+  per-viewer access filtering.
+
+## Data model
+
+New migration `167_trending_discover_snapshots`. (Originally numbered 166, but
+the shared dev DB had already recorded version 166 from another branch's
+`166_trending_blend_collection_type`; the migration runner dedupes by integer
+version, so 166 was silently skipped. Renumbered to 167, the next free version.)
+
+```
+trending_discover_snapshots
+  source          text         NOT NULL          -- 'tmdb' | 'trakt'
+  window          text         NOT NULL          -- 'day' | 'week' (trakt canonicalized to 'week')
+  content_ids     text[]       NOT NULL DEFAULT '{}'  -- ordered, resolved to library catalog, capped at 200
+  entry_count     int          NOT NULL DEFAULT 0     -- raw provider entries fetched (matched-vs-trending observability)
+  refreshed_at    timestamptz                     -- last successful refresh
+  last_attempt_at timestamptz
+  last_status     text                            -- 'ok' | 'empty' | 'error'
+  last_error      text
+  PRIMARY KEY (source, window)
+```
+
+Notes:
+
+- One row per canonical `(source, window)` — at most a handful of rows.
+- `content_ids` is catalog-matched but **viewer-agnostic**, exactly like the
+  value the current cache holds. Per-viewer access filtering still happens at
+  read time in `fetchItemsByContentIDs`, so a single row serves all viewers.
+- The list is stored at the over-fetch cap (200). The read path truncates to the
+  section's `ItemLimit`, decoupling the snapshot from per-section limits (the old
+  `fetchLimit` cache-key dimension goes away).
+- **Reliability invariant:** a failed refresh updates `last_attempt_at`,
+  `last_status`, and `last_error` but **never clears `content_ids`**. The last
+  good list keeps serving through an upstream outage.
+
+The paired `.down.sql` drops the table.
+
+## Components
+
+All new server code lives in `internal/`.
+
+### `TrendingSnapshotRepository` (new, `internal/sections/`)
+
+Thin repository over the new table:
+
+- `Get(ctx, source, window) (TrendingSnapshot, error)` — PK lookup.
+- `Upsert(ctx, snapshot) error` — insert/update on `(source, window)`.
+- `ListAll(ctx) ([]TrendingSnapshot, error)` — for future admin/inspection use
+  and tests.
+
+`Upsert` distinguishes a successful refresh (writes `content_ids`,
+`refreshed_at`, `entry_count`, `last_status='ok'|'empty'`) from a failed one
+(touches only `last_attempt_at`/`last_status='error'`/`last_error`, leaving
+`content_ids` intact).
+
+### `TrendingRefresher` (new, `internal/sections/trending_refresher.go`)
+
+Owns the upstream call. Holds `TMDBTrending`, `TraktTrending`, `ItemRepo`, the
+section repository (to enumerate used combos), and the snapshot repository. The
+existing `fetchTrendingDiscoverEntries` and `resolveTrendingDiscoverIDs` logic
+**moves here** from `fetcher.go`.
+
+`RunOnce(ctx) (json.RawMessage, error)`:
+
+1. Enumerate the distinct canonical `(source, window)` pairs from **enabled**
+   `trending_discover` sections across all scopes (parse each section's
+   `TrendingDiscoverParams`, apply the same source/window normalization the
+   section uses, collapse Trakt to `week`).
+2. For each pair: fetch the cap-200 list from the provider, resolve external IDs
+   to library content IDs, and `Upsert`.
+3. Return a JSON summary (e.g. `{combos, refreshed, empty, failed}`), mirroring
+   `CollectionSyncResult`.
+
+No used combos → no upstream calls (a dormant feature costs nothing). A
+configured-but-empty provider yields `last_status='empty'` (no error noise). A
+per-pair failure is recorded and does not abort the other pairs.
+
+### `RefreshTrendingDiscoverTask` (new, `internal/taskmanager/tasks/`)
+
+Mirrors `SyncCollectionsTask`: delegates to `TrendingRefresher.RunOnce` and
+reports progress/result data. Default trigger: hourly interval (matches the
+recipe's `DefaultCacheTTL` of 1h), plus a one-shot run at startup so the first
+snapshot lands quickly rather than after a full interval.
+
+### `Fetcher` (modified, `internal/sections/fetcher.go`)
+
+- `loadTrendingDiscoverContentIDs` now reads the snapshot row via the snapshot
+  repository and returns its `content_ids`. It drops the upstream fetch, the
+  `singleflight` group, and the `editorialCandidateCache` usage **for trending**
+  (the editorial-candidate cache remains for the editorial sections that still
+  use it).
+- `fetchTrendingDiscover` keeps its read-time responsibilities: access
+  filtering, re-ordering to trending rank, truncation to `ItemLimit`. It no
+  longer computes a `fetchLimit` for the read path.
+- The `TMDBTrending`, `TraktTrending`, and trending-only use of `ItemRepo`
+  migrate out of the read path into the refresher. The fetcher gains the
+  snapshot repository dependency.
+
+### Wiring (`cmd/silo/main.go`, `internal/api/router.go`)
+
+- Construct `TrendingSnapshotRepository` and `TrendingRefresher` (wired with the
+  TMDB/Trakt fetchers, `ItemRepo`, section repo, snapshot repo).
+- Register `RefreshTrendingDiscoverTask` alongside the other task registrations.
+- Hand the snapshot repository to the section `Fetcher`; move the upstream
+  fetchers from the fetcher wiring to the refresher wiring.
+
+## Data flow
+
+**Refresh (background, hourly + startup):**
+task → `Refresher.RunOnce` → enumerate distinct canonical `(source, window)`
+from enabled `trending_discover` sections → per pair: fetch cap-200 → resolve
+external IDs → `Upsert` snapshot.
+
+**Read (per home render):**
+`fetchTrendingDiscover` → `loadTrendingDiscoverContentIDs` reads the snapshot
+row → `fetchItemsByContentIDs` applies the viewer's access filter → re-order to
+trending rank → truncate to `ItemLimit`. No upstream call. A single PK lookup on
+a ≤6-row table — negligible next to the queries `FetchAll` already runs, so no
+in-process read cache is added (it would re-muddy the single-source-of-truth and
+is premature).
+
+## Edge behavior
+
+- **Before first sync:** snapshot absent → section renders empty (no blocking,
+  no upstream call). The startup task run closes this gap to roughly one fetch
+  duration.
+- **Provider unconfigured but a section exists:** `last_status='empty'`, no
+  error.
+- **Upstream failure on a pair that already has a snapshot:** prior
+  `content_ids` keep serving; only the attempt/status/error columns update.
+- **Trakt `day` vs `week`:** collapse to a single `week` row (Trakt ignores the
+  window).
+
+## Testing
+
+- **Repository round-trip:** upsert then get; `content_ids` ordering preserved;
+  success vs failure upsert paths.
+- **Refresher `RunOnce`:** fake `TMDBTrending`/`TraktTrending`, fake section
+  enumerator, in-memory `ItemRepo`. Assert ordered IDs upserted; `ok`/`empty`/
+  `error` transitions; and the reliability invariant — a failed refresh
+  preserves prior `content_ids`.
+- **Read path:** inject nil upstream fetchers into the fetcher and assert the
+  trending read still works from the snapshot (proves reads never call upstream).
+- **Canonicalization:** Trakt `day` and `week` resolve to one row.
+
+## Risks / follow-ups
+
+- The data captured (`refreshed_at`, `last_status`, `last_error`, `entry_count`)
+  enables a future admin/inspection surface; not built here.
+- If multiple sections request very different `ItemLimit`s, all share the cap-200
+  list and truncate — intended, and strictly more data than the old per-limit
+  cache held.

+# Multi-Instance Sonarr/Radarr Routing for Requests (Seerr-style)
+
+**Status:** Design approved, ready for implementation plan
+**Date:** 2026-06-01
+**Area:** `internal/requests`, `migrations/`, `web/src` (admin settings + request queue)
+
+## Summary
+
+Silo's request system today fulfills every approved request through a single
+Radarr (movies) or single Sonarr (series) instance, at whatever quality that
+one instance's profile is configured for. There is no 4K concept, no anime
+handling, and exactly one instance per kind (`request_integrations.kind` is the
+primary key).
+
+This work replicates Seerr's Sonarr/Radarr management model *inside* Silo's own
+request system (no external Seerr dependency):
+
+- **Many instances per kind** — N Radarr and N Sonarr servers, each with its own
+  connection, root folder, quality profile, and tags.
+- **Default HD + Default 4K routing** — one HD-default and one 4K-default
+  instance per kind; requests route to the matching default(s).
+- **Per-server anime overrides** (Overseerr-style) — each instance carries an
+  optional anime profile / root folder / tags applied when a title is detected
+  as anime.
+- **Entitlement-driven dual-quality fan-out** — a single user request can be
+  fulfilled in **both** 1080p and 2160p when the requester's `MaxPlaybackQuality`
+  allows 4K, or when an admin global toggle forces it for everyone.
+
+The end-user request action is unchanged: quality is derived from the user's
+existing entitlement, not a per-request choice.
+
+## Goals
+
+- Support multiple Radarr/Sonarr instances per kind.
+- Route by quality (HD vs 4K) to per-kind default instances.
+- Fan a single request out to both 1080p and 2160p targets based on the
+  requester's `MaxPlaybackQuality` entitlement, with an admin override that
+  forces dual-quality regardless of role.
+- Apply per-instance anime overrides using Seerr-exact anime detection.
+- Keep the request lifecycle (quotas, approval, reconcile) coherent under
+  one-to-many fulfillment.
+
+## Non-Goals
+
+- No integration *with* a Seerr instance (an earlier idea, dropped). Silo
+  remains the system of record.
+- No per-request manual server/profile picker (Overseerr's advanced UI). Routing
+  is automatic from defaults + entitlement.
+- No separate 1080p/4K *availability* tracking. The pre-request presence check
+  stays binary ("is this title in the Silo library at all").
+- No admin-configurable anime keyword list (the heuristic is isolated so one can
+  be added later).
+- No dedicated-anime-instance flag — anime is handled by per-instance overrides
+  (decided during design).
+
+## Background: current flow
+
+When a user requests a movie today (`internal/requests/service.go`):
+
+1. **Browse/discover** via TMDB; each result carries a `RequestState`.
+2. `CreateRequest` validates: requests enabled, not already available
+   (presence), not already actively requested (dedup by `tmdb_id`), computes the
+   requester's `EffectivePolicy` (quota, blocked, auto-approve), enforces quota.
+3. Auto-approve users with a configured integration → row created `approved`,
+   else `pending` for the admin queue.
+4. `submitApprovedRequest` → `integrationForMediaType(mediaType)` finds the
+   single instance by kind → `radarr.Client.SubmitMovie` POSTs to Radarr using
+   that instance's root folder / quality profile / tags → request goes `queued`.
+5. `ReconcileRequests` polls the instance: `queued → downloading → completed`
+   (or `failed`).
+
+The single insertion point that changes is step 4's instance selection.
+
+## Design
+
+### 1. Data model
+
+**`request_integrations` — reworked from one-row-per-kind to many instances:**
+
+| column | purpose |
+|---|---|
+| `id` (text PK, via `idgen`) | replaces `kind` as PK |
+| `kind` (text, `radarr`\|`sonarr`) | now a plain column, keeps its CHECK |
+| `name` (text) | admin-facing label |
+| `enabled` (bool) | |
+| `base_url`, `api_key_ref` | connection; API key stays a Fernet secret ref, never plaintext |
+| `root_folder`, `quality_profile_id`, `tags[]` | standard (non-anime) defaults |
+| `is_4k` (bool) | marks this as a 4K server |
+| `is_default` (bool) | the HD default for its kind |
+| `is_default_4k` (bool) | the 4K default for its kind |
+| `anime_enabled` (bool) | apply anime overrides on this instance |
+| `anime_quality_profile_id`, `anime_root_folder`, `anime_tags[]` | anime overrides |
+| `options` (jsonb) | kind-specific extras (Radarr min-availability, Sonarr season-folders/series-type) |
+| `last_check_*`, `created_at`, `updated_at` | unchanged |
+
+**Invariants** (partial unique indexes + service validation):
+
+- At most one `is_default` per kind; at most one `is_default_4k` per kind.
+- `is_default ⇒ NOT is_4k` and `is_default_4k ⇒ is_4k`. The HD default is an HD
+  server; the 4K default is a 4K server. HD and 4K defaults are therefore always
+  distinct instances.
+
+**New `media_request_targets`:**
+
+| column | purpose |
+|---|---|
+| `id` (bigint identity PK) | |
+| `request_id` (text → `media_requests` ON DELETE CASCADE) | |
+| `integration_id` (text → `request_integrations` ON DELETE SET NULL) | |
+| `integration_kind` (text snapshot) | survives instance deletion for history |
+| `quality` (text, `1080p`\|`2160p`) | reuses `internal/access` presets |
+| `is_anime` (bool) | which profile set was applied |
+| `external_id`, `external_status`, `status`, `last_error` | per-target Radarr/Sonarr lifecycle |
+| `created_at`, `updated_at` | |
+| UNIQUE `(request_id, quality)` | one target per quality per request |
+
+**`media_requests` changes:** the per-fulfillment columns
+(`integration_kind`, `external_id`, `external_status`) move out to
+`media_request_targets`. Add `is_anime` (bool). The request's `status` becomes an
+**aggregate** over its targets (see §3). `idx_media_requests_active_tmdb` stays —
+dedup is still one active request per title regardless of quality, and a
+dual-quality request counts as **one** row against the user's quota.
+
+### 2. Routing engine
+
+A pure function `routeTargets(req, entitlement, settings, instances) -> []plannedTarget`
+replaces `integrationForMediaType` as the selection point in
+`submitApprovedRequest`.
+
+**Inputs:** the request (incl. detected `is_anime`), the requester's
+`MaxPlaybackQuality`, the global `force_dual_quality` setting, the configured
+instances for the kind.
+
+**Algorithm:**
+
+1. **Kind** = `movie → radarr`, `series → sonarr`.
+2. **Desired qualities:**
+   - `1080p` is always desired (baseline for everyone).
+   - Add `2160p` if `access.QualityAllowed("2160p", user.MaxPlaybackQuality)`
+     **OR** `force_dual_quality` is on (the toggle overrides role).
+3. **Pick the default instance per desired quality:** `1080p → is_default`,
+   `2160p → is_default_4k` (for that kind).
+4. **Profile selection per chosen instance:** if `req.is_anime` **and** the
+   instance has `anime_enabled` → use its anime profile / root folder / tags
+   (and, for Sonarr, `seriesType: anime`); otherwise the standard set.
+5. Emit one `plannedTarget{instance, quality, isAnime, profile, rootFolder, tags}`
+   per resolved quality.
+
+**Edge cases:**
+
+- A desired quality with **no default instance assigned** is silently skipped
+  (cannot route 4K without a 4K default — matches "when both are assigned").
+- **Zero** resolved targets (e.g. no HD default configured): the request stays
+  `approved` but unfulfilled, with `last_error` = "no Radarr/Sonarr instance
+  configured for this quality" so it surfaces in the admin queue.
+- No dedup needed: the `is_default`/`is_default_4k` invariants guarantee HD and
+  4K defaults are distinct instances.
+
+### 3. Fulfillment & reconcile lifecycle
+
+The adapter interfaces (`SubmitMovie`/`SubmitSeries`,
+`CheckMovieStatus`/`CheckSeriesStatus`) are **unchanged** — they already take
+`(req, integration)`. We call them **once per target**, passing a *resolved*
+`Integration` whose `RootFolder`/`QualityProfileID`/`Tags` are filled from the
+standard or anime block. Radarr/Sonarr's notion of "4K" is just that instance's
+quality profile + root folder, so adapters stay quality-agnostic. (The Sonarr
+adapter additionally sets `seriesType: anime` for anime targets.)
+
+**On approval (`submitApprovedRequest`):**
+
+1. `routeTargets(...)` → planned targets.
+2. For each: insert a `media_request_targets` row, then call the matching
+   adapter with the resolved instance + decrypted key.
+3. On success → target `queued` with its `external_id`/`external_status`; on
+   error → target `failed` + `last_error`.
+4. **Recompute the request aggregate** in the same transaction as the target
+   writes.
+
+**Reconcile loop (`ReconcileRequests`):** for each candidate request, iterate its
+**non-terminal targets**, load each target's instance by `integration_id`, call
+the status adapter, update the target, then recompute the aggregate. Targets
+reconcile independently.
+
+**Aggregate recompute (single source of truth):**
+
+- all targets `completed` → request `completed` (+ `completed_at`)
+- any target `downloading` → `downloading`; else any `queued` → `queued`
+- all targets `failed` → `outcome = failed`; **some** failed while others active
+  → request stays active, `last_error` set from the failed target(s)
+
+**Retry** is target-aware: an admin retry re-submits only the `failed` targets
+(re-routing if instance config changed), leaving healthy targets alone.
+
+### 4. Anime detection (Seerr-exact)
+
+Detection matches upstream Seerr exactly — a single TMDB keyword id, no genre or
+language fallback:
+
+- `server/api/themoviedb/constants.ts`: `ANIME_KEYWORD_ID = 210024`
+- `server/entity/MediaRequest.ts`: anime ⇔ `keywords.results` contains that id.
+
+Implementation:
+
+- A named constant `animeKeywordID = 210024`.
+- `detectAnime(detail) bool` → true iff the TMDB keyword **ids** contain
+  `210024`. Matching by id (not the name string) avoids false positives from
+  neighboring keywords like "based on anime".
+- Detected once at `CreateRequest` time and stored on `media_requests.is_anime`,
+  so routing, reconcile, and retries stay consistent.
+- Applies to both movies and series; ignored if no instance for that kind has
+  `anime_enabled`.
+
+**Supporting TMDB-client change:** extend `tmdb.MediaDetail` to carry keyword
+**ids** (add `append_to_response=keywords` to the detail fetch). `GetMediaDetail`
+is already called in the request path, so no extra round-trip beyond the append.
+(`OriginalLanguage` is not needed under the parity-only decision but may be
+mapped opportunistically since it is already in the response.)
+
+The heuristic is isolated in one function so an admin-configurable keyword list
+can be added later without touching routing.
+
+### 5. Admin UI
+
+`web/src/pages/admin-settings/IntegrationsSettings.tsx` and the setup wizard
+`web/src/pages/setup-wizard/steps/IntegrationsStep.tsx` move from a single
+Radarr/Sonarr form to an **instance-list manager** per kind:
+
+**Per kind — list of instance cards** (add / edit / delete):
+
+- Connection: name, base URL, API key (write-only; shows "configured" once set,
+  never echoes the secret), **Test connection** → `LoadIntegrationOptions`
+  populates root-folder and quality-profile **dropdowns**.
+- Standard block: root folder, quality profile, tags.
+- Quality role: `is_4k` switch, **Default (HD)** toggle, **Default 4K** toggle.
+  The form enforces invariants client-side (no Default-HD on a 4K server;
+  selecting a new default clears the prior one visually); server is source of
+  truth.
+- Anime block (collapsible, `anime_enabled`): anime quality profile, anime root
+  folder, anime tags — dropdowns from the same test-connection options.
+
+**Request settings panel** gains the **"Always fulfill in both 1080p and 4K"**
+toggle (`force_dual_quality`) with helper text: applies to all requests when both
+a Default HD and Default 4K instance exist, regardless of user role.
+
+**`web/src/pages/AdminRequests.tsx`** (queue): each request row expands to show
+its **targets** — quality badge (1080p/2160p), instance name, per-target status,
+and per-target **retry** on failed ones. The aggregate status stays the headline.
+
+**Setup wizard** stays minimal: add one Radarr + one Sonarr, auto-marked Default
+HD. Advanced multi-instance/4K/anime config lives in the full settings page.
+
+### 6. API contract & multi-repo coordination
+
+**End-user request flow is unchanged** — quality is derived from
+`MaxPlaybackQuality`, so the request action and payload are identical (no 4K
+toggle, no new permission).
+
+**`Request` response model** gains `is_anime` and a `targets[]` array
+(`quality`, `instance_name`, `status`, `external_status`, `last_error`); the
+top-level `integration_kind`/`external_id`/`external_status` are removed in favor
+of the aggregate `status` + `targets`.
+
+- Per `CLAUDE.md`'s multi-repo rule: end-user `silo-android` / `silo-apple`
+  clients show a single aggregate status, so they likely need **no change** —
+  but this is flagged as explicit Apple/Android follow-up to verify the request
+  model tolerates the removed fields and ignores/parses the new `targets`.
+
+**Admin endpoints** change from "upsert by kind" to instance CRUD:
+
+- `GET/POST/PUT/DELETE` request integrations **by `id`**; `LoadIntegrationOptions`
+  (test-connection) stays, keyed by instance.
+- Default-toggle handled server-side transactionally (a new HD/4K default clears
+  the prior one for that kind).
+- `request_settings` gains `force_dual_quality`.
+- Admin-web-only; no mobile client surface.
+
+### 7. Migration & backfill
+
+Next migration number: **169** (`169_request_multi_instance.{up,down}.sql`).
+
+**Up:**
+
+1. `ALTER request_integrations`: add `id`, `name`, `is_4k`, `is_default`,
+   `is_default_4k`, `anime_enabled`, `anime_quality_profile_id`,
+   `anime_root_folder`, `anime_tags[]`. Backfill existing rows: `id = gen`,
+   `name = initcap(kind)`, `is_default = enabled` (the lone existing instance
+   becomes that kind's HD default), everything else default/false. Swap the PK
+   from `kind` to `id`; keep `kind` as a plain column with its CHECK.
+2. Partial unique indexes: one `is_default` per kind, one `is_default_4k` per
+   kind.
+3. `CREATE media_request_targets` (per §1).
+4. Backfill targets: for any `media_requests` row with an `external_id`, insert a
+   target `(quality='1080p', is_anime=false, integration_id = that kind's
+   instance, integration_kind, external_id, external_status, status = request's
+   current status)`. Rows never submitted get no target yet.
+5. `ALTER media_requests`: add `is_anime bool DEFAULT false`; drop
+   `integration_kind`, `external_id`, `external_status`.
+6. `idx_media_requests_active_tmdb` stays unchanged.
+
+**Down:** re-add the three columns to `media_requests` and copy back the **1080p**
+target's external fields; drop `media_request_targets`; drop `is_anime`; collapse
+`request_integrations` to `kind`-PK by keeping each kind's `is_default` instance
+and discarding extras; drop the new columns/indexes.
+
+**Caveat (explicit):** the down migration is **lossy** — rollback discards any
+additional instances (beyond one default per kind) and any 4K/anime target
+history. This is the unavoidable cost of collapsing a one-to-many back to
+one-to-one and is acceptable for a down migration.
+
+**Go-side data access** (implementation, not SQL): `Integration` struct +
+`scanIntegration` gain the new fields; the `Store` interface gains target CRUD +
+`ListInstances(kind)`; `scanRequest` drops the external fields; `UpsertIntegration`
+becomes id-based CRUD with default-toggle handling in-transaction.
+
+### 8. Testing
+
+- **`routeTargets` — table-driven (core of the feature):** matrix of
+  {1080p vs 2160p entitlement} × {`force_dual_quality` on/off} × {which defaults
+  exist} × {anime vs not} → expected target set.
+- **`detectAnime`:** keyword `210024` present/absent; no name-substring false
+  positives.
+- **Aggregate recompute:** all-complete, partial-failure (request stays active +
+  `last_error`), all-failed (`outcome=failed`), mixed downloading/queued.
+- **Repository:** target CRUD; single-default-per-kind invariant rejects a second
+  default; migration backfill yields exactly one 1080p target per previously
+  submitted request.
+- **Adapter:** Sonarr `SubmitSeries` sets `seriesType=anime` only for anime
+  targets on anime-enabled instances.
+- **Service:** extend `service_test.go` fakes — a 4K-entitled user's single
+  request fans out to two adapter submissions with the right resolved instances;
+  target-scoped retry re-submits only the failed target.
+- **Frontend:** instance-form default-invariant enforcement; queue renders
+  per-target rows + retry.
+
+## Risks & open considerations
+
+- **Reconcile cost** scales with targets, not requests (≤2× today). Bounded and
+  acceptable; the reconcile loop already batches.
+- **Anime keyword imperfection** is inherited from Seerr by design (parity
+  choice). Mitigated by isolating `detectAnime` for future tuning.
+- **Client model drift**: removing top-level external fields from `Request` must
+  be verified against `silo-android` / `silo-apple` deserialization before
+  release (flagged in §6).

+# Autoscan: Polling Radarr/Sonarr to Trigger Targeted Library Scans
+
+**Status:** Design approved, ready for implementation plan
+**Date:** 2026-06-02
+**Area:** new `internal/autoscan`, `internal/taskmanager/tasks`, `migrations/`, `internal/api`, `web/src/pages/AdminRequests.tsx`
+
+## Summary
+
+Silo currently learns about new media via scheduled/manual library scans. When
+Radarr/Sonarr import a download, the new file only appears in Silo on the next
+scan. This adds an **autoscan poller**: a periodic background task that polls the
+configured Radarr/Sonarr instances for newly-imported files and enqueues
+**targeted folder scans** into Silo's existing scan queue, so requested (and
+non-requested) content shows up promptly.
+
+The design follows the established autoscan pattern — poll arr import history,
+translate the imported paths, and trigger targeted scans — but kept deliberately
+simple. That pattern is normally built to orchestrate scans across many separate
+media-server boxes, which needs a bounded fan-out guard and a retry queue. Silo
+is a single service scanning *itself*, so the cross-node fan-out machinery is
+unnecessary — imported paths become folder jobs in Silo's own worker-bounded
+`scanqueue`.
+
+## Goals
+
+- Poll autoscan-enabled Radarr/Sonarr instances on an interval for import events.
+- Translate arr import paths into Silo media folders and enqueue targeted scans.
+- Reuse the Radarr/Sonarr instances already configured for requests
+  (`request_integrations`) — no duplicate URLs/keys.
+- Coalesce bursts (a season's episodes) into minimal redundant scans.
+- Admin-configurable: global enable, interval, debounce, per-instance toggle,
+  optional path rewrites, on-demand "poll now".
+
+## Non-Goals
+
+- No cross-node scan fan-out or bounded-concurrency semaphore (single service;
+  the `scanqueue` workers are the bound).
+- No separate retry queue (a failed source poll simply does not advance its
+  high-water mark, so the next cycle retries the window).
+- No arr webhook/"Connect" push integration (polling only, as requested; webhook
+  push is a possible future add-on).
+- No separate autoscan source credential store — sources are existing
+  `request_integrations`.
+
+## Background
+
+- **`internal/scantrigger`** already maps a filesystem path to a Silo
+  `MediaFolder` and scan path: `Resolver.Resolve(Request{Path}) -> Target{Folder,
+  Mode, Path}` (via `LongestMatchingRoot` / `MatchFolderForPath`).
+- **`internal/scanqueue`** executes scans through a worker-bounded queue:
+  `Queuer.EnqueueScan(ctx, folderID, mode, path, trigger)` /
+  `EnqueueScans(targets)`.
+- **`internal/requests/arrclient`** is a thin Radarr/Sonarr HTTP client
+  (`New(baseURL, apiKey, httpClient)`, `GetJSON`, `DoJSON`) — reused for the new
+  history call.
+- **`request_integrations`** holds each instance's `id`, `kind`, `base_url`, and
+  Fernet-encrypted `api_key_ref`, resolved via the same secret resolver the
+  request service uses.
+- The **task manager** runs periodic tasks via the `taskmanager.Task` interface
+  with interval `DefaultTriggers()` (e.g. `ReconcileRequestsTask`).
+
+## Design
+
+### 1. Data model & config
+
+A new `internal/autoscan` package owns its own schema; `request_integrations`
+stays focused on fulfillment.
+
+**`autoscan_settings`** (singleton, mirrors `request_settings`):
+
+| column | type / default | purpose |
+|---|---|---|
+| `id` | bool PK default true, singleton CHECK | |
+| `enabled` | bool, default false | master on/off |
+| `poll_interval_minutes` | int, default 10 | poll task interval |
+| `debounce_seconds` | int, default 60 | folder re-scan suppression window |
+| `created_at`, `updated_at` | timestamptz | |
+
+**`autoscan_sources`** (one row per autoscan-enabled instance):
+
+| column | type | purpose |
+|---|---|---|
+| `integration_id` | text PK → `request_integrations(id)` ON DELETE CASCADE | the source instance |
+| `enabled` | bool, default false | per-instance autoscan toggle |
+| `path_rewrites` | jsonb, default `[]` | `[{from, to}]` prefix overrides |
+| `last_poll_at` | timestamptz, null | `history/since` high-water mark |
+| `created_at`, `updated_at` | timestamptz | |
+
+**Reused, not duplicated:** `base_url` / `api_key_ref` come from
+`request_integrations`. Debounce/suppression state lives in **Redis**
+(`autoscan:scanned:{folder_id}`, TTL = `debounce_seconds`), not Postgres.
+
+### 2. Poll cycle
+
+`autoscan.Service.PollOnce(ctx)` (invoked by the periodic task):
+
+1. Load `autoscan_settings`; if `!enabled`, return immediately (no-op).
+2. Load `autoscan_sources WHERE enabled`, joined to `request_integrations` for
+   `kind` / `base_url` / `api_key_ref`.
+3. For each source (sequential — a handful of instances):
+   1. Decrypt the API key via the secret resolver.
+   2. Record `cycleStart := now`.
+   3. `arrclient.GetJSON("/api/v3/history/since?date={last_poll_at}&eventType=downloadFolderImported")`
+      — both Radarr and Sonarr expose this. `last_poll_at` null → a sane floor
+      (do not scan all history on first enable; floor at `cycleStart`).
+   4. Extract the imported **file path** per event (Radarr: movie file path;
+      Sonarr: episode file `outputPath`); take its **parent directory**.
+   5. On success, advance that source's `last_poll_at = cycleStart`. On failure
+      (arr unreachable, decode error), log and **do not** advance — next cycle
+      retries the window.
+4. For each extracted directory: apply path rewrites (§3), resolve via
+   `scantrigger.Resolver` → `Target{Folder, Mode, Path}`. Unresolvable paths
+   (outside Silo's media folders) are logged and skipped.
+5. **Dedupe to unique folders** for this cycle; for each, check the Redis
+   suppression key — if absent, `EnqueueScan(..., trigger="autoscan")` and set
+   the key with TTL `debounce_seconds`; if present, skip (already scanned this
+   window).
+
+**Debounce rationale:** because the poller batches a whole interval of imports
+per `history/since` call, within-cycle folder dedup does most of the work. The
+Redis suppression key only prevents re-enqueuing the same folder on back-to-back
+cycles. Silo's scanner is idempotent, so a season importing across two cycles
+simply gets a second (cheap) scan that picks up the rest. This is simpler than a
+"collect-expired" debounce plus a retry queue, which the polling + idempotent
+re-scan model makes unnecessary.
+
+### 3. Path resolution & scan enqueue
+
+A small pipeline in front of the existing scan plumbing — no new scan logic:
+
+1. **Rewrite** (per source, optional): apply the first matching `path_rewrites`
+   entry as a prefix replacement (e.g. `/data/media -> /mnt/media`). No rewrites
+   → path used as-is (shared-mount common case).
+2. **Resolve** via `scantrigger.Resolver.Resolve(Request{Path: rewrittenDir})`
+   → `Target{Folder, Mode, Path}`. No matching media folder → log + skip.
+3. **Enqueue** deduped targets via `scanqueue` `EnqueueScans` with
+   `trigger="autoscan"` (attributable in scan history, flows through the same
+   worker-bounded queue).
+
+### 4. Scheduling & concurrency
+
+- **`internal/taskmanager/tasks/autoscan_poll.go`** implements `taskmanager.Task`
+  (`Key: "autoscan_poll"`, name/description/category, `DefaultTriggers` = interval
+  trigger seeded from `poll_interval_minutes`). Its run body calls
+  `autoscan.Service.PollOnce(ctx)`.
+- **Disabled = cheap no-op:** the task stays registered; `PollOnce` returns early
+  when `enabled` is false. Toggling autoscan never (de)registers tasks.
+- **Interval changes:** updating `poll_interval_minutes` reconfigures the task's
+  interval trigger via the task manager's existing trigger-config path; if a live
+  update is unavailable it applies on next start.
+- **No overlap, no semaphore:** the task manager serializes a task's executions;
+  sources are polled sequentially; scan execution is bounded by `scanqueue`. The
+  single-service simplification: no bounded-fan-out semaphore is needed.
+- **Primary/integrated server only** (same as the request reconcile task), not on
+  standalone transcode/proxy worker nodes.
+
+### 5. Admin API & UI
+
+**API** (admin-gated, `/api/v1/admin/autoscan`, mirroring the request-settings
+handlers; never echoes API keys):
+
+- `GET/PUT /autoscan/settings` — `{enabled, poll_interval_minutes, debounce_seconds}`
+- `GET /autoscan/sources` — per autoscan-eligible instance (joined from
+  `request_integrations`): `{integration_id, name, kind, enabled, path_rewrites,
+  last_poll_at}`
+- `PUT /autoscan/sources/{integration_id}` — set `{enabled, path_rewrites}`
+- `POST /autoscan/trigger` — run `PollOnce` once on demand; tight per-admin rate
+  limit so it cannot hammer the arr instances
+- `GET /autoscan/status` — `{enabled, per-source last_poll_at, last scan summary}`
+
+**UI:** a new **"Autoscan" tab** in `web/src/pages/AdminRequests.tsx` (alongside
+Queue / Settings / Integrations / User Overrides):
+
+- Global controls: enable switch, poll interval, debounce window.
+- Per-source list — one row per Radarr/Sonarr instance with an autoscan toggle,
+  an optional `from → to` path-rewrite editor, and a read-only "last polled".
+- A **"Poll now"** button → `POST /autoscan/trigger`.
+
+Rate limits and admin-auth follow Silo's existing request-admin conventions.
+
+### 6. Testing
+
+- **Path rewrite:** prefix replacement, first-match ordering, no-match
+  passthrough, trailing-slash handling.
+- **arr history client:** table-driven `httptest` fixtures for both Radarr and
+  Sonarr import-event JSON shapes; asserts the correct file path is extracted and
+  its parent folder taken.
+- **Dedupe + suppression:** many paths in one folder → one target; folder with a
+  live suppression key skipped; absent/expired key enqueues.
+- **`PollOnce` (integration seam):** fakes for source store, arr history client,
+  `scantrigger.Resolver`, `scanqueue.Queuer`, Redis — asserts deduped folder
+  scans enqueued with `trigger="autoscan"`, `last_poll_at` advanced on success,
+  **not** advanced on per-source failure, clean no-op when disabled.
+- **Unresolvable path:** logged + skipped, never enqueued or fatal.
+- **Repository / migration:** `autoscan_settings` singleton + `autoscan_sources`
+  CRUD and the `request_integrations` join; migration applies + rolls back
+  (sidecar table, `ON DELETE CASCADE`).
+- **Frontend:** Autoscan tab renders, per-source toggle / path-rewrite editor
+  round-trips, "Poll now" calls the trigger endpoint.
+
+## Risks & open considerations
+
+- **First-enable floor:** `last_poll_at` null must floor at "now" (not epoch) so
+  enabling autoscan doesn't enqueue a scan for every historical import.
+- **history/since shape differences:** Radarr vs Sonarr import-event payloads
+  differ; the path extraction is per-kind and covered by fixtures.
+- **Path rewrites vs scantrigger roots:** if neither rewrites nor Silo's media
+  folders match the arr path, the import is silently skipped (logged) — this is
+  the expected "content outside Silo's libraries" behavior, but a misconfigured
+  rewrite will look like "autoscan does nothing"; the `last_poll_at` + status
+  endpoint and skip logs are the debugging surface.
+- **Idempotent re-scan:** relies on Silo's scanner being safe to run repeatedly
+  on a folder (it is — re-scan finds new files).
+
+## References
+
+- Existing Silo plumbing reused by this design: `internal/scantrigger/scantrigger.go`,
+  `internal/scanqueue/`, `internal/requests/arrclient/`,
+  `internal/taskmanager/tasks/reconcile_requests.go`
+- Prior art: the general autoscan pattern (poll arr import history → translate
+  paths → trigger targeted scans). Silo's variant drops the cross-node fan-out
+  guard and retry queue, which only a multi-box orchestrator needs.

+# Autoscan as a Pluggable Scan-Source Category — Design Spec
+
+**Date:** 2026-06-02
+**Status:** Approved design, pre-implementation
+**Goal:** Turn autoscan from a Requests-coupled, arr-only feature into a standalone **Autoscan** category whose change-detection providers are out-of-process Silo plugins, with Sonarr/Radarr as the first provider.
+
+**Architecture (one sentence):** Silo's host keeps a thin, provider-agnostic engine that resolves changed paths to library folders and enqueues rescans; each *way of noticing change* (arr, later inotify/ceph) is an installable plugin that Silo pulls on a timer through a new additive `scan_source.v1` capability.
+
+**Tech stack:** Go (silo-server host + plugins), `silo-plugin-sdk` (protobuf capability contract, consumed as a tagged module), existing `internal/plugins` + `internal/pluginhost` runtime, existing `scantrigger`/`scanqueue` scan pipeline, React/TS admin UI.
+
+Commands assume the repository root is the cwd.
+
+---
+
+## 1. Background & motivation
+
+The current autoscan implementation (delivered in the now-closed PR #43, still on local `main`) is in-process Go that:
+
+- polls Sonarr/Radarr `/api/v3/history/since` on a host timer,
+- rewrites arr-side paths to Silo paths, dedups to parent dirs,
+- resolves each to a `MediaFolder` and enqueues a targeted scan,
+- is configured against `request_integrations` rows (hard FK, `ON DELETE CASCADE`), living as a tab inside the **Requests** admin page.
+
+Two structural problems:
+
+1. **It is arr-only and not extensible.** Adding inotify, Ceph notifications, or any other change source means more bespoke host code.
+2. **It is subordinate to Requests.** A source cannot exist without a Requests integration row; deleting the row destroys the source.
+
+Silo already ships a full out-of-process plugin runtime (`internal/plugins`, `internal/pluginhost`): manifests, an installer, typed capability descriptors (`metadata_provider.v1`, `request_router.v1`, `media_analyzer.v1`, `scheduled_task.v1`, `event_consumer.v1`, …), a host-driven scheduled-task mechanism, and a rate-limited plugin→host event path. This design uses that runtime to make change-detection pluggable.
+
+## 2. Goals / non-goals
+
+**Goals**
+
+- A new **Autoscan** admin category, independent of Requests.
+- A new additive `scan_source.v1` plugin capability — **breaks no existing plugin**.
+- A **client-pull** contract: Silo asks each source "what changed since `<marker>`?" on a timer.
+- Sonarr/Radarr re-implemented as the first scan-source plugin; the closed PR's arr logic relocates into it.
+- A provider-agnostic host engine reusable by every future scan source.
+- Optional reuse of Requests' arr connection details, *or* standalone connection entry.
+
+**Non-goals (this design)**
+
+- inotify / Ceph / other providers (the contract must *accommodate* them; we do not build them).
+- A push (plugin-initiated) delivery mode. Pull only; push sources buffer internally and answer on pull (see §6).
+- Refactoring the Requests subsystem itself.

+
+**Five components**
+
+1. **`scan_source.v1`** (in `silo-plugin-sdk`) — the pull contract. §5.
+2. **AutoscanStore** (host) — generic resolve→suppress→enqueue→marker engine. §7.
+3. **Connection resolution** (host) — reference-or-inline → concrete credentials. §8.
+4. **Autoscan category + data model** (host) — sources, connections, decoupled from Requests. §9.
+5. **arr scan-source plugin** (new repo) — first provider. §10.
+
+## 4. Responsibility split (the dividing line)
+
+| Concern | Owner | Rationale |
+|---|---|---|
+| Talk to arr; poll `/history`; imports + renames; bounded window; first-run | **Plugin** | Provider-specific I/O. |
+| **Path rewrites** (per-source config + application) | **Host** | _(Revised post-merge: the SDK landed host-owned rewrites.)_ The plugin returns RAW source-namespace paths in `source_paths`; the host applies each source's rewrite rules (longest-`From`-first) before resolving. Keeps every provider dumb and rewrite behavior uniform. Rewrites are edited per-source in the Autoscan UI and stored in `autoscan_sources.path_rewrites`. |
+| Resolve Silo-native path → `MediaFolder`; dedupe; **enqueue rescan** | **Host** | Touches Silo internals (scan queue, DB, library map) that plugins cannot and must not reach. |
+| Opaque per-source marker; poll interval; enabled; last-run status | **Host** | Scheduling and bookkeeping are the engine's job. |
+| Connection selection (reuse-from-Requests vs own) and credential resolution | **Host** | Only the host knows about Requests; the plugin receives resolved creds. |
+
+The plugin's responsibility ends at **"here are the changed paths, in Silo's terms."** Everything past that is the host engine, which is provider-agnostic.
+
+## 5. The `scan_source.v1` contract (centerpiece)
+
+A new, additive capability in `silo-plugin-sdk`. Existing plugins never declare it and are unaffected (§11).
+
+### Protobuf (as implemented in silo-plugin-sdk)
+
+```proto
+// scan_source.v1 — host pulls changed paths from a provider on a timer.
+service ScanSource {
+  // Host calls this on each poll tick for a configured scan_source capability.
+  rpc PollChanges(PollChangesRequest) returns (PollChangesResponse);
+}
+
+message PollChangesRequest {
+  string capability_id = 1;          // which configured scan_source instance
+  string marker        = 2;          // opaque; empty string on first run
+  ResolvedConnection connection = 3; // resolved upstream credentials (see §8)
+}
+
+// Concrete upstream credentials the host resolves and hands to the plugin each
+// poll, so the plugin stays credential-source-agnostic and stores no secrets.
+message ResolvedConnection {
+  string base_url = 1;
+  string api_key  = 2;
+}
+
+message PollChangesResponse {
+  // Absolute changed paths in the provider/source namespace (RAW — NOT yet
+  // rewritten). Files or directories. The host applies the source's rewrite
+  // rules and validates before enqueueing.
+  repeated string source_paths = 1;
+  // Opaque continuation token. Host stores verbatim and echoes it back
+  // on the next PollChanges. The plugin never assumes the host parses it.
+  string next_marker = 2;
+}
+```
+
+### Contract rules
+
+- **Pull only.** The host owns the timer and calls `PollChanges`. The plugin never initiates.
+- **Opaque marker.** The host stores and echoes `next_marker` without interpreting it. arr uses an RFC3339 timestamp; a future provider may use a sequence number or event id — no host change required.
+- **First run.** `marker == ""` ⇒ the plugin starts from "now" (do not replay full history).
+- **Idempotent, at-least-once.** The host may re-issue the same `marker` if it failed to persist `next_marker`; providers must tolerate returning overlapping paths. The host's suppression layer (§7) absorbs duplicates.
+- **Error semantics.** A failed `PollChanges` (e.g. arr unreachable) ⇒ the host keeps the *old* marker and retries next tick; nothing is skipped or advanced.
+- **Raw source paths.** `source_paths` are in the provider's namespace, NOT rewritten. The host applies each source's path-rewrite rules (host-owned, per-source) before resolving to a library folder.
+- **Credentials per call.** The host resolves the source's connection (§8) and passes the concrete `{base_url, api_key}` in `PollChangesRequest.connection` on every poll. The plugin reads them from the request — it stores no credentials and never knows whether they came from its own config or a reused Requests link. Delivered over the local host↔plugin gRPC channel only.
+
+The capability needs **only** `PollChanges` for v1. A `TestConnection`/validate RPC is explicitly deferred (YAGNI; connection validity surfaces as a failed poll).
+
+## 6. Marker & delivery semantics
+
+- One opaque marker stored per source, host-side.
+- Pull-only does **not** exclude push-style providers: an inotify/Ceph plugin maintains its own internal buffer of observed changes and flushes it (and advances its marker) on each `PollChanges`. Cost: up to one poll-interval of latency. This keeps a single uniform contract.
+
+## 7. Host: AutoscanStore engine
+
+Provider-agnostic. Per enabled source, per tick:
+
+1. `paths, next := plugin.PollChanges(marker)`; on error, log + keep marker + continue.
+2. For each `dir` in `uniqueParentDirs(paths)`:
+   - `target := scantrigger.Resolve(dir)`. Unresolvable (outside Silo's media folders) ⇒ quiet skip.
+   - Suppression key `fmt.Sprintf("%d|%s", folderID, target.Path)` with debounce TTL; already-claimed ⇒ skip.
+   - Accumulate `target`; record claimed key.
+3. `scanqueue.EnqueueScans(targets)`. On failure, release claims and **do not** advance the marker.
+4. On success, persist `next_marker`.
+
+This is the salvaged core of PR #43 (`internal/autoscan/service.go` resolve/suppress/enqueue, `dedupe.go`, `suppress.go`), generalized so its input is "paths from a provider" rather than "paths from arr." Path-rewrite helpers (`rewrite.go`, `suggest.go`, `history.go`, the arr history client) leave the host and move into the plugin (§10).
+
+## 8. Host: Connections (reuse or own)
+
+A **connection** is "an arr server Silo can reach," created two ways:
+
+- **Own:** name + base URL + API key, entered in the Autoscan category; the key is Fernet-encrypted at rest (same mechanism as existing service credentials — never plaintext in JSONB).
+- **Linked (reuse):** a live reference to an existing Requests `request_integrations` arr server. Resolved at use-time, so edits in Requests propagate.
+
+**Resolution:** on each poll the host resolves the chosen connection (own or linked) into concrete `{base_url, api_key}` and passes them in `PollChangesRequest.connection` (§5). The plugin is credential-source-agnostic — it only ever sees resolved values, fresh each poll, so a change to a reused Requests credential propagates immediately with no re-push. This "reuse or own" behaviour is therefore free for every future provider. (Resolving per-call rather than caching in plugin config also means no decrypted secret is ever stored at rest in the plugin.)
+
+**Decoupling from Requests:** the link is **soft and optional** — `SET NULL` / surfaced-as-"needs attention", never cascading. Requests has no knowledge of Autoscan. Autoscan and Requests are peers; Autoscan merely *offers* to borrow a Requests connection.
+
+## 9. Host: Autoscan category & data model
+
+New top-level **Autoscan** admin section (its own nav entry, not a Requests tab). Manages **Connections** (§8) and **Sources**.
+
+A **source** corresponds to one configured `scan_source.v1` capability instance and carries:
+
+- **Host-owned per-source config:** path rewrites (`autoscan_sources.path_rewrites`, edited in the Autoscan Sources UI) and any provider-specific settings. _(Revised post-merge: rewrites moved host-side; the plugin has no config.)_
+- **Host-owned per-source state:** the chosen connection, enabled on/off, poll interval (per-source, not one global timer), the opaque marker, and last-run status/error.
+
+**Install flow + source auto-discovery (resolves §14 risk #1).** A scan-source plugin (Sonarr/Radarr, etc.) is installed through the **normal `/admin/plugins`** page — there is no separate install path; the installer doesn't special-case the capability type. Source rows are then never created by hand: the host enumerates every installed `scan_source.v1` capability (via the plugin installation store) and *seeds a disabled, connection-less row* per capability (`INSERT … ON CONFLICT (installation_id, capability_id) DO NOTHING`, never disturbing existing config). Discovery runs **both on each poll cycle AND when the Autoscan sources list is viewed** (so a freshly-installed plugin appears in Autoscan immediately, even when autoscan is disabled and nothing is polling). The operator then binds a connection and enables it. Consequently **`connection_id` is nullable**: a freshly-discovered source has none, and the engine skips any enabled source with no connection (recording a "no connection bound" status). The admin API rejects enabling a source that has no effective connection.
+
+**Per-source interval** is honoured as a floor: the global poll task runs at `default_poll_interval_seconds`, and within a cycle the engine skips a source whose `last_run_at` is newer than its own `poll_interval_seconds` (falling back to the default). A source therefore polls *at most* every N seconds, never more often than the global cadence.
+
+### Schema changes (host)
+
+Rework the PR #43 tables; **no FK into `request_integrations`**:
+
+- `autoscan_connections` — `id`, `name`, `kind` (e.g. `sonarr`/`radarr`), and *either* own credentials (`base_url`, `api_key_ref` encrypted) *or* a nullable soft link `request_integration_id` (`ON DELETE SET NULL`).
+- `autoscan_sources` — `id`, `(installation_id, capability_id)` (unique; the discovered identity), **nullable** `connection_id → autoscan_connections` (`ON DELETE RESTRICT`; null until the operator binds one), `enabled`, `poll_interval_seconds` (nullable; null = use default), `marker` (opaque text, nullable), `last_run_at`, `last_error`. Creation-time validity for connections (own creds OR a link) is enforced at the application layer (the DB CHECK would conflict with `ON DELETE SET NULL` on the reuse link).
+- `autoscan_settings` (optional) — retain a global enable + default interval; per-source interval overrides it.
+
+A migration supersedes PR #43's `171_autoscan` schema (which is not yet upstream, so this is a forward redefinition, not a production migration of live data on `origin/main`).
+
+## 10. Plugin: Sonarr/Radarr scan-source
+
+A new installable repo structured like `silo-plugin-tmdb` (standalone Go module, `manifest.json` declaring `scan_source.v1`, gRPC `main.go`, depends on the new tagged `silo-plugin-sdk`). Receives resolved arr `{base_url, api_key}` as config. Implements `PollChanges`:
+
+1. Treat `marker` as the "since" timestamp (empty ⇒ now).
+2. Call arr `/api/v3/history/since`, capped by a bounded window (24h max-lookback floor + overlap buffer — relocated from PR #43) so a long outage cannot pull an oversized response.
+3. Extract paths: **imports** (`downloadFolderImported.importedPath`) and **renames** (`episodeFileRenamed`/`movieFileRenamed`: both new `path` and old `sourcePath`). Deletes ignored (upgrade-deletes are covered by the paired import; standalone deletes carry no path).
+4. Return `{source_paths = the RAW arr paths, next_marker = newest history timestamp}`. The plugin does NOT rewrite — the host normalizes separators and applies the source's rewrite rules. _(Revised post-merge.)_
+
+**Rewrite config + "Sync from arr":** the rewrite list and the suffix-match suggester (which matches arr root folders to Silo media folders) live in the plugin. The suggester needs Silo's media-folder list, obtained via the existing host library-listing service (`internal/pluginhost` library lister) exposed to plugins. The relocated logic is PR #43's `suggest.go`/`suggest_deps.go`/`rewrite.go`/`history.go`.
+
+## 11. Backward compatibility (hard requirement)
+
+Adding `scan_source.v1` **must not break existing plugins.** It doesn't, by construction:
+
+- Capabilities are independent opt-in declarations. Each host subsystem **filters for its own type and ignores the rest** (verified: `metadata_provider.v1`, `scheduled_task.v1`, `event_consumer.v1`, … each use `if type != mine { skip }`). There is **no global allowlist that rejects unknown capability types.**
+- **Additive-only rule:** the SDK change *adds* new proto messages/service + a new capability string. It never modifies the shape of an existing capability. (Mutating an existing capability is the only thing that would break plugins; we forbid it.)
+- **No forced upgrades:** existing plugin repos stay pinned to their current SDK version and build unchanged. Only a plugin that *wants* to be a scan source adopts the new SDK version.
+
+## 12. Build order & repo decomposition
+
+One shared contract, three repos (+ catalog), in dependency order:
+
+1. **`silo-plugin-sdk`** (long pole): define `scan_source.v1` (proto + generated code + manifest helper + runtime server scaffold), tag a new version (e.g. `v0.5.0`). The tagged release is a hard serialization point — host and plugin cannot build against the contract until it exists.
+2. **silo-server (host)** — bump SDK dep; build AutoscanStore (generalized), the `scan_source.v1` caller (timer → `PollChanges`), connections + resolution, the Autoscan category UI, retire the in-process arr autoscan, add the reworked migration. *Parallelizable with (3) once (1) is tagged.*
+3. **arr plugin (new repo)** — depends on SDK `v0.5.0`; implement `PollChanges`, rewrites, "Sync from arr", bounded window.
+4. **`silo-plugins`** (catalog) — add the entry so the arr plugin is installable.
+
+Each repo gets its **own implementation plan** (separate `writing-plans` pass); this single spec defines the shared contract and per-side responsibilities they all build against.
+
+**Local logistics:** only `silo-server` and `silo-plugin-tmdb` are currently checked out. Implementation will require `silo-plugin-sdk` and a new arr-plugin repo (and later `silo-plugins`) available locally.
+
+## 13. Salvage map (from closed PR #43)
+
+| PR #43 code | Destination |
+|---|---|
+| arr `/history` client, imports + renames, bounded window (`history.go`) | arr plugin |
+| path rewrite apply (`rewrite.go`) + "Sync from arr" suggester (`suggest.go`, `suggest_deps.go`) | arr plugin |
+| `last_poll_at` cursor | host, generalized to opaque per-source `marker` |
+| resolve + dedupe + suppress + enqueue (`service.go`, `dedupe.go`, `suppress.go`) | host AutoscanStore (generic) |
+| `171_autoscan` schema (FK → `request_integrations`) | host, reworked: `autoscan_connections` + `autoscan_sources`, no requests FK |
+| Autoscan admin tab under Requests (`AdminRequests.tsx`) | host, as its own Autoscan category |
+
+## 14. Risks & open questions
+
+1. **Plugin multiplicity for multiple arr servers.** Does the runtime support multiple configured instances of one plugin (one per arr server), or is config per-installation only? If the latter, "two Sonarrs + one Radarr" implies either multiple installations or a plugin that manages several connections internally. *Resolve before the host/plugin plans by reading `internal/plugins` installation + capability-instance handling.*
+2. **Plugin config UI richness.** The rewrite table + a "Sync from arr" action are richer than typical key-value plugin config. Verify the plugin config-schema/admin-config UI can host a structured list and an action button; if not, design a minimal affordance (e.g. suggester runs on first configure, or a dedicated plugin HTTP route via `http_routes.v1`).
+3. **Library-folder list exposure to plugins.** Confirm the `internal/pluginhost` library lister is reachable by a `scan_source` plugin for the suggester. If not, add a host service method.
+4. **Marker persistence vs at-least-once.** Ensure marker write happens only after successful enqueue, matching PR #43's "don't advance on failure" guarantee.
+5. **Closed PR disposition.** The in-process autoscan on local `main` (34 commits) should be removed/replaced rather than shipped; sequence the host plan to retire it cleanly.
+
+## 15. Testing strategy
+
+- **SDK:** proto compiles; manifest helper round-trips `scan_source.v1`; runtime scaffold serves `PollChanges`.
+- **Host engine:** table-driven tests for resolve→suppress→enqueue→marker (port PR #43's `service_test.go`, generalized to a fake `ScanSource` client): dedupe, distinct-paths-same-folder, disabled no-op, poll failure keeps marker, enqueue failure releases claims + keeps marker, opaque-marker pass-through. Run in the libvips-equipped environment (host handler tests link libvips via CGO — see workspace note).
+- **Connections:** resolution of own vs linked; linked falls back gracefully when the Requests row is deleted (`SET NULL`).
+- **arr plugin:** history parsing (imports + renames, ignores unrelated events), rewrite application, bounded window, first-run "from now"; suffix-match suggester cases (unique/ambiguous/covered/no-op/normalization) ported from PR #43.
+- **Compat:** an existing-style plugin manifest with no `scan_source.v1` is unaffected by host scan-source dispatch.
+
+## 16. Out of scope / future
+
+- inotify and Ceph-notify scan-source plugins (the contract accommodates them via the buffer-and-flush pattern of §6).
+- A push/event delivery mode, if pull latency ever proves insufficient.
+- A `TestConnection` RPC on the capability.
+- Migrating Requests onto a shared connection abstraction (today's reuse is a one-directional soft link only).

+# Autoscan: Sync Path Rewrites from Arr Root Folders
+
+**Status:** Design approved, ready for implementation plan
+**Date:** 2026-06-02
+**Area:** `internal/autoscan`, `internal/api`, `web/src/pages/AdminRequests.tsx`
+**Extends:** the autoscan feature (`docs/superpowers/specs/2026-06-02-autoscan-arr-polling-design.md`)
+
+## Summary
+
+Autoscan resolves an imported file path against Silo's media folders, but
+Radarr/Sonarr often report files under paths that differ from how Silo mounts
+the same content — so operators must hand-author per-root `path_rewrites`. For a
+multi-instance, many-root deployment this can be dozens of rows.
+
+This adds a **"Sync rewrites from arr"** convenience: for one instance, query its
+root folders, match each root to a Silo media folder by **shared trailing path
+segments**, and present the resulting `{from, to}` rewrites as a **preview** the
+admin reviews and commits. Manual rewrites remain the source of truth; sync only
+*fills the editor* — nothing persists until the admin saves.
+
+The matcher is purely structural (no assumptions about any particular path
+layout) so it helps any deployment whose arr and Silo share folder names at some
+depth, and degrades gracefully (no shared names → "unmatched" → manual entry)
+when they do not.
+
+## Goals
+
+- One-click suggestion of `path_rewrites` for an instance from its arr root folders.
+- Correct disambiguation when multiple Silo folders share a leaf name.
+- Preview-then-commit: the admin sees proposed/unmatched/ambiguous and saves
+  through the existing per-source save. Manual rows are never removed or overwritten.
+- Deployment-agnostic: no hard-coded paths; works for any structure; surfaces
+  match confidence so weak matches can be rejected.
+
+## Non-Goals
+
+- No automatic/background writing of rewrites — the admin always commits.
+- No new persistence path — apply is the existing `PUT /sources/{id}`.
+- No case-insensitive matching (case-sensitive segments; correct on Linux). A
+  toggle can be added later if needed.
+- No "sync all instances at once" — per-instance, matching the editor UI.
+
+## Design
+
+### 1. Matching function (core, pure)
+
+A single side-effect-free function in `internal/autoscan`:
+
+```go
+func suggestRewrites(arrRoots []string, siloFolderPaths []string, existing []PathRewrite) RewriteSuggestions
+```
+
+```go
+type RewriteSuggestions struct {
+    Proposed  []ProposedRewrite `json:"proposed"`
+    Unmatched []string          `json:"unmatched"`
+    Ambiguous []AmbiguousRoot   `json:"ambiguous"`
+    Covered   []string          `json:"covered"`
+}
+type ProposedRewrite struct {
+    From       string `json:"from"`         // arr root
+    To         string `json:"to"`           // matched Silo folder path
+    MatchDepth int    `json:"match_depth"`  // trailing segments shared (confidence)
+}
+type AmbiguousRoot struct {
+    Root       string   `json:"root"`
+    Candidates []string `json:"candidates"`
+}
+```
+
+**Normalization** (applied to every path before comparison): backslashes → `/`
+(reuse `normalizeSeparators`), strip a trailing `/`, collapse duplicate slashes.
+This makes any path format (POSIX, Windows, single- or many-root) comparable.
+
+**Per arr root:**
+1. **Covered-first:** if any `existing` rewrite's `From` already matches the root
+   (exact, or root starts with `From + "/"`, using the same boundary rule as
+   `applyRewrites`), classify as **Covered** and skip — so sync never re-proposes
+   what a manual or broad rule already handles.
+2. Split both the root and each Silo folder path into segments; compute the
+   **longest common trailing-segment suffix** (full-segment equality, so `4ktv7`
+   does not match `4ktv70`).
+3. Among Silo folders, take the maximum suffix length `> 0` and the folders that
+   achieve it:
+   - exactly one → **Proposed** `{From: root, To: folder, MatchDepth: n}`
+   - more than one → **Ambiguous** `{root, candidates}`
+   - zero → **Unmatched**
+
+No deployment constants appear in the function; it operates only on the string
+slices it is given.
+
+### 2. Preview endpoint & service
+
+**Endpoint:** `GET /api/v1/admin/autoscan/sources/{id}/rewrite-suggestions` →
+`RewriteSuggestions` JSON (admin-gated, like the other autoscan routes).
+
+**Service method** `Service.SuggestRewrites(ctx, integrationID) (RewriteSuggestions, error)`:
+1. `Repository.GetSource(id)` — a new single-source variant of the existing join
+   that returns `kind`/`base_url`/`api_key_ref`/`path_rewrites` even when the
+   source is disabled. Not found → `ErrIntegrationNotFound`.
+2. Decrypt the API key via the existing `SecretResolver`.
+3. `RootFolderClient.RootFolders(ctx, baseURL, apiKey)` → arr root paths.
+4. `FolderLister.ListFolderPaths(ctx)` → all Silo media-folder paths.
+5. Return `suggestRewrites(arrRoots, siloPaths, source.PathRewrites)`.
+
+**Two new narrow `Service` dependencies** (injected like `history`/`resolver`):
+- `RootFolderClient.RootFolders(ctx, baseURL, apiKey string) ([]string, error)` —
+  an `arrclient`-backed impl reusing `arrclient.ListRootFolders` (returns paths only).
+- `FolderLister.ListFolderPaths(ctx) ([]string, error)` — a thin adapter over
+  `catalog.FolderRepository.List()` flattening each folder's `Paths`.
+
+**Wiring:** both constructed where the autoscan handler is built in `router.go`
+(`deps.FolderRepo` already in scope; the arr client is trivial). The handler's
+service interface gains `SuggestRewrites`.
+
+**Errors:** instance not found → 404; arr unreachable / bad key → 502 with the
+arr error surfaced; Silo folder-list failure → 500.
+
+No new write path — the frontend merges `proposed` into the editor and the admin
+saves via the existing `PUT /sources/{id}`.
+
+### 3. Frontend (preview UI)
+
+In `AutoscanSourceEditor` (`web/src/pages/AdminRequests.tsx`), add a **"Sync from
+arr"** button beside Save. On click, a new hook
+(`useAutoscanRewriteSuggestions`) calls the endpoint and opens a preview panel:
+
+- **Proposed** — each row: `From → To` + a **confidence badge** from `match_depth`
+  (e.g. "3 segments" strong, "1 segment — weak"), with a checkbox (default checked).
+- **Unmatched** — info-only list of arr roots with no Silo match ("add manually").
+- **Ambiguous** — arr root + candidate Silo paths (info-only; admin adds a manual row).
+
+**"Add selected to rewrites"** merges the checked proposals into the editor's
+existing rewrite rows, **deduped by `from`, never removing manual rows**. The
+admin then clicks the normal **Save**. New types in `web/src/api/types.ts`
+(`AutoscanRewriteSuggestions`, `ProposedRewrite`, `AmbiguousRoot`) and hook in
+`web/src/hooks/queries/useAutoscan.ts`. Reuse existing
+`Button`/`Badge`/`Dialog`/`Field` primitives.
+
+### 4. Testing

+- **`suggestRewrites`** — table-driven, fixtures spanning layouts: multi-segment
+  match, single-segment unique, longest-suffix disambiguation (`Anime/Subs` vs
+  `Anime2/Subs`), unmatched (no shared segment), already-covered via a broad
+  prefix rule, an ambiguous tie, plus **unlike-this-deployment** cases
+  (`/data/Movies` arr vs `/library/Films` Silo → unmatched; `/srv/tv/Show` vs
+  `/tank/television/Show` → leaf match) and normalization (trailing slash,

+# Autoscan source labels — design
+
+**Date:** 2026-06-05
+**Status:** Approved, pending implementation plan
+**Scope:** Admin UI labeling of autoscan scan sources, generic across plugins, plus an operator-editable per-source label.
+
+Commands assume the repository root is the cwd.
+
+## Problem
+
+Autoscan sources are labeled in the admin UI (Sources tab and Activity tab) by their
+`capability_id` plus `plugin #<installation_id>`. The `arr` scan-source plugin fans out
+one source per connection (Sonarr, Sonarr4k, Radarr, Radarr4k) under a single generic
+`arr` capability, so every row rendered an identical "arr (plugin #4)" label. A prior
+change made the Sources/Activity labels lead with the bound connection name, which fixes
+`arr`, but the fallback for any other plugin is still the cryptic `capability_id` +
+`plugin #N`.
+
+Two gaps remain:
+
+1. **Other plugins look cryptic.** A connectionless plugin (e.g. cephfs) or any future
+   plugin still falls back to the raw `capability_id`, ignoring the human-friendly
+   `display_name` the plugin already declares in its manifest.
+2. **No operator control.** An operator cannot name a source themselves. This is the only
+   fully-general answer for plugin shapes the automatic chain cannot disambiguate (e.g. a
+   single plugin installation creating several connectionless sources distinguished only
+   by their `source_config`).
+
+## Goals
+
+- Generic, plugin-agnostic labels driven by metadata that already exists
+  (manifest `display_name`, connection `name`), so future plugins look good with **no
+  host code per plugin**.
+- An optional operator-editable label per source that overrides the automatic chain.
+- A single shared label-resolution helper, consumed by both the Sources and Activity
+  panels, so the logic is not duplicated.
+
+## Non-goals
+
+- Plugin-declared label templates in the manifest/SDK (the "option C" from brainstorming).
+  Deferred: it requires a cross-repo SDK/manifest contract change. The chain below leaves a
+  clean seam for it.
+- Backend-side label resolution returned on API payloads. The resolution stays in the
+  frontend helper for now; promote it to the backend only if the mobile clients need the
+  same labels.
+
+## Resolution chain
+
+A source's display label resolves through four rungs, most-specific first:
+
+```
+operator label  ->  connection name  ->  manifest display_name  ->  capability_id
+```
+
+- **operator label** — the optional per-source text the admin sets (this design's new field).
+- **connection name** — the operator-named `autoscan_connections.name` bound to the source.
+- **manifest display_name** — from the plugin manifest, surfaced by the
+  `scan-source-plugins` endpoint (`AutoscanAvailableSource.display_name`).
+- **capability_id** — last-resort raw identifier; never worse than today.
+
+The chosen rung is the **title**. The remaining identity (plugin display name / capability +
+`plugin #<installation_id>`) renders as a **subtitle**, so no information is lost when a
+higher rung wins. Example: operator label `4K Movies` as title, `Radarr4k · plugin #4` as
+subtitle.
+
+### Per-plugin behavior
+
+| Source shape | Title | Subtitle |
+| --- | --- | --- |
+| arr, connection bound, no operator label | `Radarr4k` (connection) | `arr · plugin #4` |
+| arr, operator label set | `4K Movies` (operator) | `Radarr4k · plugin #4` |
+| cephfs, no connection | `CephFS Watcher` (manifest display_name) | `plugin #5` |
+| future plugin, nothing declared | `capability_id` | `plugin #N` |
+| Activity event whose source was deleted (`source_id` null) | manifest display_name or `capability_id` from the event's stored fields | `plugin #N` |
+
+## Components
+
+### Shared helper — `web/src/lib/autoscanLabels.ts` (new)
+
+Pure, React-free, unit-tested.
+
+- `composeSourceLabel({ operatorLabel, connectionName, displayName, capabilityId, installationId })`
+  `=> { name: string; detail: string }` — implements the four-rung chain and the
+  subtitle composition.
+- `pluginDisplayNameKey(installationId, capabilityId) => string` — stable map key.
+- `buildPluginDisplayNames(available: AutoscanAvailableSource[]) => Map<string, string>` —
+  builds the `installation_id + capability_id -> display_name` lookup both panels use.
+
+Future seam: `composeSourceLabel` may later accept an optional `configLabel` rung (for the
+deferred plugin-template option) without changing either panel's call shape.
+
+### Migration — `migrations/174_autoscan_source_label.{up,down}.sql` (new)
+
+```sql
+-- up
+ALTER TABLE public.autoscan_sources ADD COLUMN label text NOT NULL DEFAULT '';
+-- down
+ALTER TABLE public.autoscan_sources DROP COLUMN label;
+```
+
+`label` empty string = unset; the resolution chain falls through to the automatic rungs.
+174 is a fresh, unused migration number (no collision with the reused-172 history).
+
+### Backend (Go)
+
+- `internal/autoscan/types.go` — add `Label string` to the `Source` struct and the source
+  input type.
+- `internal/autoscan/repository.go` — add `label` to `sourceColumns`, `scanSource`, and the
+  create/update statements.
+- `internal/api/handlers/autoscan.go` — accept `label` on source update; include it in the
+  `autoscanStatusSource` and source responses. Trim whitespace and cap length at 120
+  characters server-side.
+
+### Frontend
+
+- `web/src/api/types.ts` — add `label` to `AutoscanSource` and `AutoscanSourceInput`.
+- `web/src/pages/admin/autoscan/SourcesPanel.tsx` — replace the inline `sourceIdentity`
+  block with a call to `composeSourceLabel`. Add an optional "Label" text input to the
+  source row, saved on blur via the existing `fullBody` PATCH path (mirrors the interval
+  field's `handleIntervalBlur` auto-save). Build the display-name map from the existing
+  `useAvailableScanSources()` query.
+- `web/src/pages/admin/autoscan/ActivityPanel.tsx` — add `useAvailableScanSources()`, build
+  the display-name map, map `source_id -> source` to obtain the operator label and
+  connection, and route `pollSourceName` / `scanSourceName` through `composeSourceLabel`,
+  returning `.name`. Preserve the existing `"Autoscan"` fallback for scans with no
+  capability.
+
+## Edit UX
+
+Inline per-row, reusing the existing on-blur auto-save pattern (no modal, no new
+interaction model). The label input is blank by default with placeholder text indicating
+it is optional. Saving sends the full row state through the same source-update mutation
+used for connection/interval/rewrites.
+
+## Error handling and edge cases
+
+- **Deleted source on an Activity event** — `autoscan_events.source_id` is
+  `ON DELETE SET NULL`; with a null `source_id` there is no operator label or connection,
+  so the chain resolves from the event row's own stored `capability_id` / `installation_id`
+  (plus manifest display_name if the plugin is still installed).
+- **Uninstalled plugin** — `display_name` does not resolve; the chain falls to
+  `capability_id`.
+- **Bound connection** — `autoscan_sources.connection_id` is `ON DELETE RESTRICT`, so a
+  bound connection always resolves to a name.
+- **Length / whitespace** — the operator label is trimmed and capped at 120 characters
+  server-side; an all-whitespace label normalizes to empty (unset).
+
+## Testing
+
+- `web/src/lib/autoscanLabels.test.ts` — covers each rung of the chain: operator label
+  wins, connection name wins, manifest display_name wins, capability fallback, and the
+  subtitle composition.
+- Extend the existing autoscan repository/handler Go tests to cover the `label` column
+  round-trip (create/update/read) and the server-side trim + length cap.
+
+## Scope summary
+
+One migration pair, three Go files, four frontend files (one new). No SDK changes, no
+multi-repo coordination. Operator-editable labels (this design) and the automatic chain
+share the same helper, so the deferred plugin-template option layers on later with no
+rework.

+# Marker sources & TheIntroDB contribution — design
+
+**Date:** 2026-06-06
+**Status:** Draft (rev 2), pending review
+**Scope:** Review the current TheIntroDB marker integration, formalize a multi-source
+marker-provider model (query-all / best-wins), and add the ability to contribute Silo's own
+markers back to TheIntroDB. This round designs the **server-side API and data model only** —
+web-admin and mobile surfaces are deferred to a UI-only follow-up. No client (Android/Apple)
+changes required.
+
+Commands assume the repository root is the cwd.
+
+**Rev 2 changes:** contribution is configured **per provider** (off by default); all new web
+UI is **deferred** and the backend API is specified in full instead.
+
+## Decisions locked for this design
+
+These were chosen up front and constrain everything below:
+
+1. **Deliverable now:** design/plan only. No source changes land from this document; it is
+   the blueprint a follow-up implementation plan expands.
+2. **What we contribute:** *both* local auto-detected markers *and* manual corrections. Local
+   detection only produces **intro markers for episodes**, so credits/recap/preview and all
+   movies can only be contributed via manual correction — this asymmetry drives the design.
+3. **Account model:** a single server-wide TheIntroDB account, reusing the existing
+   `introdb.api_key` server setting. Per-user accounts are a noted future seam, not built now.
+4. **Multi-source dispatch:** query all enabled online sources and keep the highest-quality
+   result per segment ("best wins"). This makes *real per-segment confidence* (gap #2 below)
+   a hard prerequisite, not an optional nicety.
+5. **Contribution is configured per provider, off by default.** Every contribution-capable
+   provider has its own enable switch and submit settings, so when more providers exist an
+   operator chooses *which* ones to submit to. Both the master contribute switch and the
+   auto-submit-local-detections switch default to off; a single setting flips each on.
+6. **API-first, UI deferred.** This round fully specifies the backend (manual marker
+   read/write/clear, contribution trigger + status, per-provider provider config, key
+   validation and stats) so any future surface — web admin or mobile — builds on a complete
+   contract. No new web UI is designed here beyond noting where it will eventually attach.
+
+## Problem
+
+Silo currently detects intro/recap/credits/preview markers from two places — a local
+chromaprint/chapter analyzer (`internal/intromarkers`) and the online TheIntroDB provider
+(`internal/markers/introdb`) — reconciled by a source-priority ladder at write time. The
+online side is cleanly abstracted behind a `markers.Provider` interface and a
+`markers.Registry`, which is good, but three things are missing:
+
+1. The current TheIntroDB provider has **correctness gaps** measured against the real v3 API
+   contract (TVDB lookups dropped, real confidence discarded — see "Review findings").
+2. There is **no path to contribute** Silo's markers back to TheIntroDB, even though the v3
+   API exposes a submission endpoint and the package was deliberately built read-only.
+3. The provider abstraction is **fetch-only and first-hit**, so it does not yet support
+   "several online sources, keep the best answer" or "this source can also accept
+   contributions, and I choose which sources to submit to."
+
+## Review findings — current implementation
+
+### What is already right (keep it)
+
+- **Clean source abstraction.** `markers.Provider` (`ID()`, `FetchMarkers()`) + `markers.Registry`
+  with `FetchFirstHit` (`internal/markers/types.go`). TheIntroDB is *not* hardcoded; a second
+  provider is one `Register()` call (`cmd/silo/main.go`).
+- **Multi-source-aware schema.** `media_files` carries per-segment provenance for all four
+  kinds: `{intro,credits,recap,preview}_markers_{source,provider,confidence,algorithm,detected_at}`
+  (migrations 108/109/137).
+- **Write-time reconciliation across source classes.** `CanWriteMarker`
+  (`internal/markers/write.go`) + `MarkerSourcePriority` (`internal/models/marker_source.go`):
+  `manual(4) > online/plugin(3) > s3(2) > scanner(1)`, confidence breaks ties. Local detection
+  uses its own priority-gated path (`intromarkers.Repository.PatchIntroMarker`).
+- **Solid HTTP hygiene** in `internal/markers/introdb/client.go`: conservative rate limiter
+  (2 req/s, burst 5; documented limit is 30 req/10s), retry with exponential backoff,
+  `Retry-After` handling, 24h TTL cache with negative caching, hot-reloadable API key over
+  Redis pub/sub.
+
+### Gaps (measured against TheIntroDB's own v3 client + Jellyfin plugin)
+
+| # | Gap | Evidence | Impact |
+|---|-----|----------|--------|
+| 1 | **TVDB lookups silently dropped.** Provider reads only TMDB+IMDB; client can't send `tvdb_id`. | `internal/markers/introdb/provider.go` (reads `ExternalIDKeyTMDB`/`IMDB` only); `client.go` `FetchEpisode/FetchMovie` build `tmdb_id` else `imdb_id`. | Titles matched only by TVDB (very common for anime / TheTVDB-first libraries) get **zero** markers, even though the resolver already populates `TvdbID` and the v3 API + both official clients support `tvdb_id`. Correctness bug. |
+| 2 | **Real confidence + submission_count discarded; hardcoded 0.9.** | `internal/markers/introdb/types.go` `segmentTimestamps` has only `start_ms`/`end_ms`; `pickMarker` sets `Confidence: 0.9`. | The `/media` response carries per-segment `confidence` and `submission_count`. Without them, "best wins" merging can't rank sources, and write-time confidence tie-breaks are meaningless. Hard blocker for the chosen dispatch model. |
+| 3 | **Naive multi-candidate selection.** `pickMarker` takes the *first* usable entry. | `internal/markers/introdb/provider.go`. | When several candidates remain (e.g. no duration match), first-usable may not be the most-submitted/highest-confidence. Minor today (duration narrows the set), but compounds once we rank by confidence. |
+| 4 | **No contribution path** (by design). | `internal/markers/introdb/types.go` package doc: "Submissions are intentionally not supported." | The whole point of this effort. |
+| 5 | **Provider is fetch-only.** No submit capability in the interface. | `markers.Provider` in `internal/markers/types.go`. | Contribution needs an optional `Submitter` capability so non-contributing sources don't have to implement it, and so submission is per provider. |
+| 6 | **No key validation / contribution stats.** | `IntroDBCredentialCard` in `web/src/pages/admin-settings/IntegrationsSettings.tsx` only sets the key. | v3 exposes `GET /v3/user/stats` to validate a key and show contribution totals/streaks. Useful "connect & verify" probe, currently absent from the API. |
+| 7 | **Single collapsed confidence in the write payload.** `BuildUpdatePayload` promotes one max confidence across all segments. | `internal/markers/write.go`. | The DB has *per-segment* confidence columns, but a merged result (intro from source A, credits from source B) can't populate them independently until per-segment confidence is threaded through the payload. Coupled to gap #2. |
+
+## Authoritative API contract (TheIntroDB v3)
+
+Confirmed from TheIntroDB's own `theintrodb` npm client (`src/funcs.ts`, `src/types.ts`) and
+the official Jellyfin plugin (`TheIntroDbClient.cs`). Base URL: `https://api.theintrodb.org/v3`.
+
+### `GET /media` — read (public; optional key)
+
+Query: one of `tmdb_id` / `tvdb_id` / `imdb_id` (preference order tmdb → tvdb → imdb),
+plus `season` + `episode` together for TV, plus optional `duration_ms` (selects the closest
+release version). Optional `Authorization: Bearer <key>` additionally includes that user's
+*pending* submissions.
+
+Response — each segment kind is an array of:
+```jsonc
+{ "start_ms": 30000|null, "end_ms": 90000|null, "confidence": 0.93|null, "submission_count": 7|null }
+```
+`start_ms:null` = "from the beginning" (intro/recap); `end_ms:null` = "to the end"
+(credits/preview). Arrays may hold multiple entries (multiple release versions) — pick by
+duration match, then by `submission_count`/`confidence`.
+
+### `POST /submit` — contribute (requires key)
+
+`Authorization: Bearer <user key>` required; submissions are credited to that account.
+Body (one segment per call):
+```jsonc
+{
+  "tmdb_id": 1234,            // required
+  "imdb_id": "tt0903747",     // optional
+  "type": "tv" | "movie",
+  "segment": "intro" | "recap" | "credits" | "preview",
+  "season": 1,                // TV only (number, or "1,2,3" multi-select)
+  "episode": 1,               // TV only
+  "video_duration_ms": 2760000, // optional, strongly recommended (release-version match)
+  "start_ms": 0|null,         // intro/recap may be null (= beginning)
+  "end_ms": 90000|null        // credits/preview may be null (= end)
+}
+```
+Response: `{ "submissions": [ { "id": uuid, "status": "pending"|"accepted"|"rejected",
+"weight": number, ... } ] }`. Submissions enter as `pending`; the backend weight-averages
+timestamps across submissions and moderates to accepted/rejected.
+
+Validation rules to mirror client-side: intro/recap require an **end**; credits/preview
+require a **start**; TV requires season+episode; movies omit them; max timestamp 6h
+(21,600,000 ms); `video_duration_ms` is 0 (unknown) or ≥ 300,000 ms.
+
+### `GET /user/stats` — validate key + contribution stats
+
+`Authorization: Bearer <key>`. Returns `{ total, accepted, pending, rejected,
+acceptance_rate, current_streak, best_streak, total_time_saved_ms, top_media }`. A 2xx with no
+`error` means the key is valid. This is both our key-validation probe and the stats display.
+
+### Rate / usage limits
+
+429 responses carry `X-RateLimit-{Limit,Remaining,Reset}` and `X-UsageLimit-{Limit,Remaining,Reset}`.
+Reads count against the rate limit; **submissions count against the usage limit**. The
+contribution pipeline must honor `X-UsageLimit-Reset` and back off — reuse the existing
+limiter and add usage-limit awareness.
+
+## Target architecture
+
+Three layers, each independently shippable. Layer A is pure correctness and unblocks B and C.
+
+### Layer A — Correctness foundation (gaps #1, #2, #3, #7)
+
+- **TVDB in the client + provider.** Add `tvdb_id` to the query builder in
+  `internal/markers/introdb/client.go` (`FetchEpisode`/`FetchMovie` gain a `tvdbID` arg,
+  preference tmdb → tvdb → imdb, cache keys extended). Provider reads
+  `req.ExternalIDs[markers.ExternalIDKeyTVDB]`. Resolver already supplies it — no resolver
+  change.
+- **Capture confidence + submission_count.** Extend `segmentTimestamps` with
+  `Confidence *float64` and `SubmissionCount *int`; add `SubmissionCount int` to
+  `markers.Marker`; `pickMarker` uses the real confidence (fallback to a named default
+  constant, e.g. `0.9`, only when the field is null) instead of hardcoding.
+- **Best-candidate selection.** `pickMarker` ranks candidates by `(submission_count desc,
+  confidence desc)` after duration filtering, instead of first-usable.
+- **Per-segment confidence in the payload.** Replace the single `Confidence *float64` on
+  `markers.MarkerUpdatePayload` with per-segment confidence (e.g. `IntroConfidence`,
+  `CreditsConfidence`, …) so a merged multi-source result writes the correct
+  `{kind}_markers_confidence` per kind. Update `BuildUpdatePayload` and the
+  `scanner.FileRepository.UpsertMarkers` column mapping accordingly.
+
+### Layer B — Multi-source dispatch ("query all, best wins")
+
+- **`Submitter` capability (optional interface).**
+  ```go
+  // internal/markers/types.go
+  type Submitter interface {
+      Provider
+      SubmitMarker(ctx context.Context, req SubmissionRequest) (SubmissionResult, error)
+      // FetchUserStats validates the configured key and returns contribution stats.
+      FetchUserStats(ctx context.Context) (UserStats, error)
+  }
+  ```
+  Only `introdb.Provider` implements it; the contribution service type-asserts
+  `provider.(markers.Submitter)`. This is also what makes contribution per-provider: the
+  service only ever submits to registered providers that satisfy `Submitter` *and* are enabled
+  in `marker_provider_config` (C6).
+
+- **Merge dispatch.** Add `Registry.FetchMerged(ctx, req) (Result, bool, error)` that fans out
+  to all *fetch-enabled* providers concurrently (bounded), then merges **per segment kind**
+  keeping the candidate with the highest `(submission_count, confidence)`. `FetchFirstHit`
+  stays as the trivial single-provider path / fallback. With only TheIntroDB enabled,
+  `FetchMerged` behaves identically to today — zero behavior change until a second source
+  exists.
+
+- **Cross-source-class reconciliation is unchanged.** `FetchMerged` reconciles *within* the
+  online class; `CanWriteMarker` still arbitrates online vs scanner vs manual at write time.
+  No double logic.
+
+- **Provider enable/order config.** Driven by the `marker_provider_config` table (C6):
+  `fetch_enabled` selects which providers are queried, `fetch_priority` is the merge
+  tiebreaker. The metadata `library_provider_chains` DB pattern (`internal/metadata/chain.go`)
+  is the upgrade path *if* per-library control is ever needed — noted, not built.
+
+- **Future plugin sources (deferred seam).** A `marker_provider.v1` plugin capability would let
+  third-party sources plug in. The clean seam is a `PluginMarkerProvider` adapter implementing
+  `markers.Provider` (mirroring `internal/metadata/plugin_provider.go`), so the registry never
+  changes. Cross-repo (silo-plugin-sdk) — explicitly out of scope here.
+
+### Layer C — Contribution to TheIntroDB
+
+#### C1. Submission client
+
+Add to `internal/markers/introdb/client.go`:
+- `SubmitSegment(ctx, SubmissionRequest) (SubmissionResult, error)` → `POST /v3/submit`,
+  Bearer key **required** (error early if `introdb.api_key` is empty), usage-limit aware.
+- `FetchUserStats(ctx) (UserStats, error)` → `GET /v3/user/stats`.
+`introdb.Provider` implements `markers.Submitter` by delegating to these.
+
+#### C2. What is eligible to contribute
+
+A marker is contributable iff:
+- the target provider is a registered `Submitter` with `contribute_enabled = true` (C6), and
+- its segment source ∈ `{scanner, manual}` (**never** `online` — that came *from* an online
+  provider; contributing it back is circular), and
+- the file resolves to a usable external ID (tmdb/tvdb/imdb) via the existing resolver, and
+- for **auto** contribution: provider `contribute_auto_local = true`, source = `scanner`,
+  kind = `intro`, confidence ≥ that provider's `contribute_min_confidence`. (Local detection is
+  intro-only/episodes-only.)
+- for **manual** contribution: any kind, episodes or movies, source = `manual`.
+
+#### C3. Manual marker API (write path; UI deferred)
+
+Markers live on `media_files`, and an item can have several versions, so the manual API is
+**file-scoped** for precision, with an item-level convenience resolver. All under the existing
+`RequireAdmin` group (`internal/api/middleware/auth.go`). New `internal/api/handlers/admin_markers.go`:
+
+- `GET /admin/files/{fileId}/markers` — current per-segment values **plus full provenance**
+  (`source`, `provider`, `confidence`, `algorithm`, `detected_at`) for each of
+  intro/recap/credits/preview. The read side an editor (or a script) needs.
+- `PUT /admin/files/{fileId}/markers` — upsert the **manual** layer. Body carries, per segment,
+  either `{start, end}` (seconds) or `null` to clear that segment's manual value. Writes
+  `source = manual` (priority 4, beats every other source) through the existing priority-gated
+  `scanner.FileRepository.UpsertMarkers` path, then notifies live sessions via
+  `playback.MarkerUpdateNotifier.MarkersUpdated` (mirrors `admin_intro.go`).
+- `DELETE /admin/files/{fileId}/markers/{segment}` — explicit single-segment clear.
+- `GET|PUT /admin/items/{id}/markers` — item-level convenience that resolves to the primary
+  file (and reports the per-version set), for callers that don't track file IDs.
+
+**Clear semantics.** Clearing a manual segment nulls that segment's value and provenance;
+`markers_source` drops to the next-highest segment still present. A subsequent local
+re-detection or online lazy-fetch can repopulate it. (We can't "un-overwrite" a value a manual
+edit replaced, so clearing means "remove the manual value," not "restore the previous source.")
+
+**Validation** mirrors the contribution rules so a manual edit can always be contributed:
+`end > start`; intro/recap may omit start (= 0); credits/preview may omit end (= file
+duration); values within [0, file duration].
+
+A web editor (player-chrome control with a "use current time" helper) attaches to this API
+later; its UX is intentionally **out of scope** for this round.
+
+#### C4. Contribution tracking (idempotency + audit)
+
+The audit log that makes submission idempotent and lets us report status. Per-provider by
+construction (the `provider` column), so the same marker can be tracked/submitted to several
+providers independently.
+
+```sql
+-- migrations/<next>_marker_contributions.up.sql  (next free number at implementation time)
+CREATE TABLE public.marker_contributions (

+);
+CREATE INDEX marker_contributions_file_idx ON public.marker_contributions(media_file_id);
+```
+
+`content_hash` over the *value* gives idempotency: the same times are never resubmitted to the
+same provider, but a manual correction (different times → different hash) submits the new
+value — which is exactly how TheIntroDB's weighted averaging expects corrections to arrive.
+
+#### C5. Contribution service + triggers
+
+A single `internal/markers/contribute.go` `ContributionService` funnels both triggers:
+`resolve enabled submitter providers (C6) → per provider: eligibility (C2) → idempotency check
+(hash vs marker_contributions) → Submitter.SubmitMarker → persist result`. Triggers:
+- **Manual / on-demand:** `POST /admin/files/{fileId}/contribute` (C7) submits a file's eligible
+  markers to enabled providers (optionally scoped to one provider/segments).
+- **Auto local detections:** a daily `ContributeMarkersTask` (`internal/taskmanager/tasks/`)
+  that, for each provider with `contribute_enabled && contribute_auto_local`, scans for episode
+  files with `intro_markers_source = 'scanner'` and `intro_markers_confidence ≥` that provider's
+  `contribute_min_confidence` lacking a current-hash `marker_contributions` row, and submits
+  them rate/usage-limited. Runs after the existing 03:30 detection task.
+
+#### C6. Per-provider configuration
+
+Contribution and fetch behavior is **per provider**, so a single global toggle won't do.
+Credentials stay in `server_settings` (sensitive handling: `introdb.api_key`); behavioral
+config moves to a new table keyed by provider id:
+
+```sql
+-- migrations/<next>_marker_provider_config.up.sql
+CREATE TABLE public.marker_provider_config (
+    provider                  text PRIMARY KEY,                -- 'introdb'
+    fetch_enabled             boolean NOT NULL DEFAULT true,   -- queried during reads (Layer B)
+    fetch_priority            integer NOT NULL DEFAULT 100,    -- merge tiebreaker
+    contribute_enabled        boolean NOT NULL DEFAULT false,  -- master submit switch (off)
+    contribute_auto_local     boolean NOT NULL DEFAULT false,  -- auto-submit local detections (off)
+    contribute_min_confidence double precision NOT NULL DEFAULT 0.95,
+    updated_at                timestamptz NOT NULL DEFAULT now()
+);
+INSERT INTO public.marker_provider_config (provider, fetch_enabled) VALUES ('introdb', true);
+```
+
+- A provider's submissions require `contribute_enabled = true`. With it on, **manual**
+  corrections submit on demand; **auto** submission of local detections additionally requires
+  `contribute_auto_local = true`. Both contribute flags default off — "easily enabled with a
+  setting," exactly one row per provider.
+- This same table carries the Layer B fetch enable/order, so "which providers do we read from"
+  and "which do we submit to" live in one place. New providers insert a row (contribute off).
+- Surfaced and edited through the provider API (C7), so the future admin surface lists
+  providers generically rather than hard-coding `introdb`.
+
+The `markers.mode` / `markers.lazy_playback` globals and the `introdb.api_key` credential are
+unchanged.
+
+#### C7. Admin provider + contribution API (fully fledged)
+
+The complete backend surface, all under `RequireAdmin`, so a UI is purely additive later:
+
+- `GET /admin/markers/providers` — list every registered provider: id, whether it is a
+  `Submitter`, its `marker_provider_config` row, and (best-effort, cached) live `/user/stats`
+  for submitter providers that have a key.
+- `PUT /admin/markers/providers/{provider}` — update that provider's config row
+  (`fetch_enabled`, `fetch_priority`, `contribute_enabled`, `contribute_auto_local`,
+  `contribute_min_confidence`). Validated; unknown provider → 404.
+- `POST /admin/markers/providers/{provider}/validate` — validate the configured key and return
+  fresh `UserStats` (calls `Submitter.FetchUserStats`). Non-submitter → 400.
+- `POST /admin/files/{fileId}/contribute` — submit this file's eligible markers (C2) to enabled
+  submitter providers; optional body `{provider?, segments?[]}` to scope to one provider /
+  specific kinds. Returns per (provider, segment) `SubmissionResult`. Honors idempotency (C4):
+  unchanged values are skipped, not resubmitted.
+- `GET /admin/files/{fileId}/contributions` — contribution history for the file from
+  `marker_contributions` (per provider/segment: status, submitted_at, error).
+
+Plus the manual marker endpoints from C3. Together these cover read, edit, submit, and audit
+without any web code.
+
+## Data model summary
+
+- **New table `marker_contributions`** (C4) — idempotent submission audit, keyed per
+  (file, provider, segment, value-hash).
+- **New table `marker_provider_config`** (C6) — per-provider fetch + contribute behavior,
+  seeded with `introdb` (fetch on, contribute off).
+- **No new flat server settings.** `introdb.api_key`, `markers.mode`, `markers.lazy_playback`
+  are unchanged; behavioral provider config lives in `marker_provider_config`, not string keys.
+- **No new marker columns.** Per-segment confidence columns already exist; Layer A only changes
+  how they're *populated* (per-segment instead of collapsed). `submission_count` stays
+  transient (merge-ranking only) unless a later need appears.
+
+## Client / cross-repo impact
+
+- **No Android/Apple changes required.** This adds no new marker *kinds* and no new
+  client-facing read contract: markers still flow to clients via the existing `WatchDetail`
+  fields, the jellycompat `GET /MediaSegments` endpoint, and the `markers_updated` realtime
+  event. Manual editing and contribution are server-side (admin API); their eventual UI is
+  deferred web-admin work.
+- **Plugin SDK:** untouched. `marker_provider.v1` is a deferred future capability (Layer B
+  seam), not part of this work.
+- A future *per-user* contribution model (each user links their own TheIntroDB account) *would*
+  be client work (a "Connect TheIntroDB" screen) — explicitly deferred.
+
+## Build sequence
+
+Each phase is shippable on its own; later phases depend only on earlier ones. Every phase is
+**backend-only** — no web UI.
+
+1. **Phase 1 — Correctness foundation (Layer A).** TVDB lookups; capture
+   confidence/submission_count; best-candidate selection; per-segment confidence in the
+   payload. *Directly answers "are we doing this properly," low risk, no new surface.*
+2. **Phase 2 — Multi-source dispatch + provider config (Layer B + C6).** `Submitter` interface;
+   `FetchMerged` query-all/best-wins; `marker_provider_config` table + repo driving fetch
+   enable/order. *No behavior change with only TheIntroDB enabled.*
+3. **Phase 3 — Submission client + tracking + service (C1, C4, C5 core).** `SubmitSegment` /
+   `FetchUserStats`; `marker_contributions` migration + repo; `ContributionService` (eligibility,
+   idempotency, per-provider gating).
+4. **Phase 4 — Manual marker API (C3) + provider/contribution API (C7).** File- and item-level
+   manual read/write/clear; provider list/config/validate; per-file contribute + history. The
+   full admin contract, no UI.
+5. **Phase 5 — Auto-contribution (C5 task).** `ContributeMarkersTask`: per provider, when
+   `contribute_enabled && contribute_auto_local`, submit episode intro markers above the
+   provider's `contribute_min_confidence`, usage-limit aware, idempotent.
+
+Deferred (separate UI-only follow-up): web admin surfaces over C3/C6/C7 — a marker editor in
+the player chrome and a provider/contribution panel in admin settings.
+
+## Risks & trade-offs
+
+- **Data-quality / pollution.** Auto-submitting chromaprint detections (confidence 0.65–0.90)
+  risks polluting a provider's data. Mitigation: `contribute_enabled` and `contribute_auto_local`
+  default **off** per provider, and the default `contribute_min_confidence` of 0.95 admits only
+  chapter / chapter+silence detections even once enabled. Manual, high-trust corrections are the
+  intended first contribution. Revisit chromaprint auto-submission after watching acceptance
+  rates via `/user/stats`.
+- **Single-account weighting.** All contributions credit one server account; TheIntroDB's
+  weighting may treat a single account's mass submissions differently than many users'. Note
+  the per-user seam; acceptable for v1.
+- **Circular contribution.** Never contribute `source = online`. Enforced in C2 eligibility and
+  worth a unit test.
+- **Usage limits.** Bulk auto-submission can hit the submission usage limit; the task must obey
+  `X-UsageLimit-Reset` and resume next run. Idempotency means an interrupted run safely resumes.
+- **"Query all" cost.** `FetchMerged` issues one lookup per fetch-enabled provider; with only
+  TheIntroDB it's identical to today, and per-provider caching bounds the cost as sources are
+  added.
+- **Movies & non-intro segments** have no local detector, so their only contribution route is
+  manual correction — acceptable and explicit.
+
+## Open questions for review
+
+1. **Contribute to all enabled providers, or require explicit per-call selection?** The design
+   defaults `POST /admin/files/{id}/contribute` to "every enabled submitter," with an optional
+   `provider` scope. Acceptable, or should submission always name its target provider?
+2. **Manual-clear behavior.** Clearing a manual segment removes the manual value and lets a
+   later detection/fetch repopulate it (we can't restore the exact pre-edit value). Is
+   "remove, then re-detect" the right contract, or do you want a marker history/undo stack?
+3. **Per-provider config home.** This design uses a `marker_provider_config` table (clean for N
+   providers, future per-library override) rather than flat `server_settings` keys. Confirm the
+   table is the direction you want.
+
+## File-level blueprint
+
+**Backend (Go) — Layer A**
+- `internal/markers/introdb/client.go` — *modify*: `tvdb_id` query support; cache-key extension.
+- `internal/markers/introdb/types.go` — *modify*: `confidence`/`submission_count` fields.
+- `internal/markers/introdb/provider.go` — *modify*: read TVDB; real confidence; best-candidate pick.
+- `internal/markers/types.go` — *modify*: per-segment confidence in `Marker`/Result plumbing.
+- `internal/markers/write.go` — *modify*: per-segment confidence in `MarkerUpdatePayload` + `BuildUpdatePayload`.
+- `internal/scanner/file_repo.go` — *modify*: map per-segment confidence in `UpsertMarkers`.
+
+**Backend (Go) — Layer B + per-provider config**
+- `internal/markers/types.go` — *modify*: `Submitter` interface; `SubmissionRequest`/`Result`, `UserStats`; `Registry.FetchMerged`.
+- `internal/markers/provider_config.go` — *create*: `marker_provider_config` repo (load/update; drives fetch enable/order + contribute gating).
+- `migrations/<next>_marker_provider_config.{up,down}.sql` — *create*.
+
+**Backend (Go) — Layer C**
+- `internal/markers/introdb/client.go` — *modify*: `SubmitSegment` (`POST /v3/submit`), `FetchUserStats` (`GET /v3/user/stats`), usage-limit handling.
+- `internal/markers/introdb/provider.go` — *modify*: implement `markers.Submitter`; drop the "submissions not supported" note in `types.go`.
+- `internal/markers/contribute.go` — *create*: `ContributionService` (eligibility, idempotency, per-provider gating, submit, persist).
+- `internal/markers/contribution_repo.go` — *create*: `marker_contributions` CRUD + value-hash check.
+- `migrations/<next>_marker_contributions.{up,down}.sql` — *create*.
+- `internal/api/handlers/admin_markers.go` — *create*: manual marker read/write/clear (C3) + per-file contribute + history (C7 file endpoints).
+- `internal/api/handlers/admin_marker_providers.go` — *create*: provider list/config/validate (C7 provider endpoints).
+- `internal/api/router.go` — *modify*: register the new `RequireAdmin` routes.
+- `internal/taskmanager/tasks/contribute_markers.go` — *create*: daily auto-contribution task.
+- `cmd/silo/main.go` — *modify*: wire `ContributionService`, provider-config repo, the task, and the `Submitter`.
+
+**Frontend (React/TS) — deferred (not this round)**
+- Marker editor over `PUT /admin/files/{id}/markers`; provider/contribution panel over the C7
+  endpoints; `IntroDBCredentialCard` "validate key & show stats". Listed for traceability only.
+
+**Reference (read-only, not in this repo)**
+- TheIntroDB v3 contract verified against `github.com/TheIntroDB/theintrodb-npm`
+  (`src/funcs.ts`, `src/types.ts`, `docs/`) and `github.com/TheIntroDB/jellyfin-plugin`
+  (`TheIntroDB/Api/*.cs`).
