54507d236a fix(watchstate): make series mark-watched atomic and unload-proof (#645)
Marking a large series as watched only marked some episodes when the user
navigated away or closed the tab. POST /watched/{id} expanded a series to
every episode and then did four sequential DB round-trips per episode — a
duration lookup, a progress upsert, a stable-identity resolution (itself an
episode lookup plus a series provider-ID lookup), and a history insert — all
on the request context with no transaction. A 200-episode series was ~800
sequential queries, each committing on its own, so a disconnect mid-loop left
everything already committed in place.

Server:
- episodeTargets now resolves durations through the existing batched
  listEpisodeFiles helper instead of one file query per episode. The shared
  mediaFileDurationSeconds keeps the batched and single-item paths in step.
- ResolveHistoryIdentities resolves a whole series in one episode query plus
  one provider-ID query per distinct series, behind optional-capability
  interfaces with per-ID fallbacks.
- New userstore.WatchedBatchWriter capability, implemented transactionally in
  both Postgres and SQLite, with a per-target fallback for stores that lack
  it. recordMarkWatched and jellycompat's recordMarkWatchedBatch share it.

A cancelled request now rolls back to "nothing marked" rather than stranding
a half-watched series, which is the correct all-or-nothing semantic and needs
no detached context.

Client: the watched mutation sends keepalive so the request survives
navigation and tab close, plus an optimistic played flip with rollback,
following the existing favorites.ts pattern.

Routing jellycompat through the shared path would have clobbered known
durations with 0, since that caller supplies none; the batch upsert only ever
advances a duration, matching what MarkProgressBatch did before.

4e03f4b807 fix(playback): last-write-wins progress and DV P7 RPU strip on remux (#334)
* fix(playback): last-write-wins progress and DV P7 RPU strip on remux

Progress: UpdateProgress (the live playback-session path) clamped
position_seconds to GREATEST(new, old), so a deliberate backward seek
could never persist — "rewind and stop" resumed at the stale later
position on every client. Position is now last-write-wins, matching the
/sync/progress path that was always unconditional. The completed latch
and rewatch re-entry semantics are unchanged.

Remux: profile 7 Dolby Vision remuxes drop the enhancement-layer track
(-map 0:v:0 keeps only the base layer) but previously left the dangling
dual-layer RPUs on the BL — broken metadata that a DV-honoring display
can mis-render. Remuxes of P7 files now strip DV RPUs via the dovi_rpu
bitstream filter, yielding a clean HDR10 stream (the same fallback
presentation the Apple client's P7 HDR10 toggle produces). Profile 8
RPUs are kept: the BL is self-contained and DV clients render it.
Adds MediaFile.PrimaryDVProfile() and threads the profile through
ServeRemux callers; the proxy path (no track metadata in claims) keeps
prior behavior.

True P7->8.1 DV conversion needs dovi_tool alongside FFmpeg (the
dovi_rpu bsf only strips/recompresses); the remux plumbing now carries
the DV profile so that can slot in later.

* fix(userdb): apply last-write-wins progress to the SQLite backend too

Review follow-up (P2): the LWW change only covered pgstore; the SQLite
userdb UpdateProgress kept the MAX clamp, so rewind-and-stop still
resumed at the stale later position for sqlite-backed installs. The
conflict clause now matches Postgres (position last-write-wins,
completed latch and rewatch re-entry unchanged), with a backward-seek
regression test.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* fix(playback): harden LWW progress and DV RPU strip from review

- Probe ffmpeg for the dovi_rpu bitstream filter once per process and fall
  back to a no-strip remux (the pre-existing behavior) when it is missing:
  on pre-7.1 ffmpeg the unknown filter aborted the process, turning every
  Dolby Vision profile 7 remux into a hard playback failure.
- Skip zero-position heartbeats in persistProgress, mirroring the stop path
  and the jellycompat report path. Under last-write-wins an early zero
  heartbeat (e.g. before the client seeks to its resume point) would wipe
  the stored resume position; GREATEST previously masked this.
- Carry the DV profile in stream token claims (dvp, omitempty) so standalone
  proxy nodes strip profile 7 RPUs the same way integrated mode does. Old
  tokens decode as 0 and keep prior behavior.

9cae868a27 feat(downloads): offline sync for mobile — downloads v2 (#258)
* feat(downloads): offline sync for mobile (downloads v2)

Replace internal/download with a unified internal/downloads package and add
fully-offline download + watch-sync support for mobile clients, across five
independently-shippable phases:

- Phase 0: reshape the downloads table and the /downloads contract to be
  device- and format-aware; add GET /downloads/capability; extend
  DownloadConfig (default-off keys); update the web download hooks/components in
  lockstep. This is the one approved pre-lock exception to the additive-only
  /api/v1 rule (the web app is the only consumer and is updated together).
- Phase 1: managed device-library entries (create/list/PATCH/delete/serve),
  keyed on the X-Silo-Device-Id header.
- Phase 2: offline playback manifest plus artwork/subtitle proxy endpoints that
  strip every presigned URL (inline thumbhashes + authenticated proxies).
- Phase 3: prepare-to-file (remux + transcode-to-single-file) as a durable,
  leased artifact queue with startup recovery, hosted on the task manager;
  playback.PrepareFile emits one +faststart MP4. Adds the admin transcode
  toggle and per-artifact LRU cleanup.
- Phase 4: offline progress reconciliation -- a clamped event_at LWW key plus a
  server-assigned synced_seq cursor on watch_progress; an optional clamped
  updated_at on POST /sync/progress and an opaque ?since= cursor on
  GET /progress (additive; existing callers unaffected).

Security & reliability invariants, each with an acceptance test:
1. Server-owned sync ordering: ?since= delta delivery is driven only by the
   server-assigned synced_seq; the client clock is bounded (event_at, clamped
   to now+skew) and used only for last-write-wins on the caller's own profile.
2. Full profile+device authorization on every managed endpoint, with a
   per-profile content/library access re-check before serving any bytes/assets.
3. Durable artifact recovery: a transactionally-claimed (FOR UPDATE SKIP
   LOCKED), lease-heartbeat, attempt-counted queue with a startup sweep, so no
   crash strands a download in preparing and concurrent workers never
   double-encode.

Migrations are timestamped Goose files: reshape downloads (device/format);
download_artifacts (durable queue); watch_progress event_at/synced_seq.

DB-backed acceptance tests skip without SILO_TEST_DATABASE_URL and run in CI;
the invariant-1 progress test also runs against the real SQLite backend locally.

Client repos (silo-android, silo-apple) consume the reshaped /downloads/*
contract and the updated_at/?since= progress fields and require coordinated
follow-up.

Implements the maintainer-approved v1 capability proposal for offline sync
(downloads v2).

AI-use disclosure: implemented by Claude (Claude Code) from the approved design
doc under docs/superpowers/specs, with human review.

* feat(downloads): series & season downloads + client-pull monitoring

Build season downloads and a "monitor a series" capability on top of the
downloads v2 (offline sync for mobile) work.

Season downloads:
- POST /downloads accepts season_number (with series:true) to download one
  season. CreateSeries/CreateSeason share one body via a listEpisodes closure
  and register managed entries under a shared batch_id (original-only). Episode
  files are resolved in a single batched query.

Series monitoring (auto-download), client-driven:
- New device-scoped download_subscriptions table with a Sonarr-style mode
  (all | future | latest_season | specific_seasons), a client-enforced
  delete_watched flag, and a max_storage_bytes cap. The server never deletes
  on-device files; retention and the hard cap are the client's, the server
  only soft-gates registration.
- The client calls POST /downloads/subscriptions/sync on open / background
  refresh; the server registers the in-scope, not-yet-downloaded episodes
  (idempotent via the managed-entry unique index) and the device pulls them on
  its own schedule. No background worker and no dependency on the notifications
  subsystem. latest_season follows new seasons (>= subscribe-time season);
  future excludes the back catalog via air date.
- Subscription CRUD + sync are profile+device authorized (device id from the
  X-Silo-Device-Id header only) with a per-request content-access re-check. The
  capability endpoint advertises season_download / series_monitoring /
  monitoring_modes.

Also lands the downloads-v2 work already present in the tree: durable artifact
(remux/transcode) preparation and offline watch-progress reconciliation, plus
the design-spec updates.

* WIP: epitaxy pre-switch from feat/downloads-v2-offline-sync

* test(downloads): fix deterministic ID collision in reconcile test

Artifact IDs are time-sortable, so two artifacts created in the same
moment share their first 8 chars; combined with a captured timestamp the
two preparing-download IDs collided on downloads_pkey. Use the full
artifact ID, which is unique per row.

* fix(downloads): support sqlite userdb backend for managed downloads

With the sqlite userdb backend, profiles live only in per-user SQLite
stores and public.user_profiles stays empty, so user_devices'
profile FK made every managed create/subscription/offline-sync request
fail with an FK violation. Drop the FK (shared Postgres tables must not
FK profile tables — same rule as notifications) and replace the lost
cascade with an app-level purge on profile deletion, wired through
ProfileHandler for both backends. DB-backed regression tests cover the
no-Postgres-profile-row path and the purge cascade.

* fix(downloads): dispatch encode kick asynchronously

triggerDrain invoked the kick inline, and the kick (taskmanager RunTask)
executes the encode task on the caller's goroutine — so a POST
/api/v1/downloads with a bitrate quality blocked the HTTP request on the
entire queue drain, ffmpeg encodes included, delaying the 202 by minutes
on an idle queue. Dispatch the kick on a goroutine; the task manager
already serializes concurrent runs.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* fix(downloads): enforce per-user quota on the encode pipeline

Two gaps let a user bypass MaxConcurrentPerUser entirely for prepared
downloads: artifact-backed rows are created in 'preparing' (never
'queued'/'downloading'), which CountActiveByUser didn't count, and
createArtifactDownload enqueued the encode job before limiter.Check, so
even a 429-rejected request left a job the worker would transcode.
Count 'preparing' as active and check the limiter before Ensure; managed
replacements stay quota-exempt since they don't add a row.

* fix(downloads): protect ephemeral artifact links from LRU eviction

HasActiveLink only counted managed (device_id IS NOT NULL) rows, so
under a byte budget Cleanup could delete an artifact still referenced by
a ready-but-unfetched ephemeral web download — permanently 404ing a row
the API kept listing as ready (the artifact row is gone, so recovery
can't re-queue it). Any non-terminal link now protects the artifact;
only artifacts whose links are all cancelled/failed/revoked are
evictable.

* fix(downloads): batch manifests skip bad entries instead of failing whole batch

One deleted or access-filtered episode made GET
/downloads/batches/{id}/manifests 404 for the entire season, so a
client could no longer fetch manifests for the still-valid entries.
Report unbuildable entries in a skipped[] array (revoked | not_found |
error) alongside the delivered manifests, mirroring the create path's
skip idiom. Also cut the batch cost: the shared series detail is
resolved once per batch instead of once per episode, and buildSubtitles
reuses the already-loaded media file instead of re-querying it per
manifest.

* fix(migrations): wrap DO block in StatementBegin/End markers

Under NO TRANSACTION goose splits statements on semicolons, so the
dollar-quoted DO block failed every fresh install with 'unterminated
dollar-quoted string' (SQLSTATE 42601). Already-applied databases are
unaffected. Same fix is being applied to main; identical content merges
cleanly.

* fix(api): allow season 0 (Specials) in season downloads

season_number was a plain int dispatched with '> 0', so requesting the
Specials season was indistinguishable from omitting the field and
silently broadened to a full-series download. Dispatch on pointer
presence, treat 0 as the Specials season, and reject negatives with 400.

* fix(downloads): capability quality_presets is never JSON null

PresetsFor returned a nil slice when downloads are disabled or the user
lacks the permission, and Capability's []string{} initialization was
immediately overwritten by it — so GET /downloads/capability serialized
"quality_presets": null where the contract documents an array.
Normalize at the source so every caller inherits the guarantee.

* fix(downloads): subscription sync correctness + batched registration

Three subscription fixes:

- A paused subscription no longer syncs: PATCHing scope (or pausing and
  changing scope in one request) registered episodes for a monitor the
  user had just stopped, inconsistently with SyncSubscriptions' guard.
- SubModeFuture compares calendar days (UTC): air_date is date-only, so
  the strict instant comparison permanently excluded episodes airing the
  same day the user subscribed; episodes with no air date now fall back
  to their ingest time instead of never registering.
- Registration is one batched fetch (GetManagedEntriesByKeys) plus one
  batched INSERT ... ON CONFLICT DO NOTHING RETURNING
  (CreateManagedEntriesBatch) instead of a SELECT+INSERT per episode —
  a 300-episode series cost ~600 sequential round trips per request and
  every no-op sync re-walked the full set. RETURNING yields exactly the
  new rows, so the sync response's 'registered' count now honestly
  reports 0 in the steady state instead of the full in-scope count on
  every app open. The now-unused InsertManagedEntryIfAbsent is removed.

* fix(userstore): stamp triggers own the event_at LWW key

MarkProgressBatch (jellycompat series mark-played) advanced updated_at
but never event_at, and both stamp triggers only defaulted event_at when
NULL — so a queued offline event with a client time between the row's
old event_at and the mark could win SetProgressIfNewer and resurrect a
stale resume position that then re-synced to every device.

Make the triggers authoritative instead of adding a tenth hand-written
SET clause: whenever an UPDATE changes updated_at without explicitly
changing event_at, the trigger advances the LWW key; writes that do set
event_at (offline sync's clamped client event time) keep their value.
Postgres gets a CREATE OR REPLACE migration; SQLite gets a v12 userdb
migration that drops and reinstalls the trigger bodies (CREATE TRIGGER
IF NOT EXISTS never replaces). Conformance tests cover both batch paths,
the preserved-client-time invariant, and the v11→v12 upgrade.

* fix(downloads): lifecycle hygiene — squash migrations, dead status, stale-row sweeps

Migrations: fold the 20260621 corrective migration back into the base
Downloads V2 migrations (its columns/constraints already exist there)
and fix the reshape Down, which re-added the narrow status CHECK without
collapsing managed-lifecycle rows first — rollback aborted on any DB
with preparing/ready/revoked rows; validated against a live row. Branch
databases that applied the corrective migration need its version row
removed: DELETE FROM goose_db_version WHERE version_id = 20260621020459.

Code: drop the dead 'registered' status (nothing ever wrote it; the
lifecycle is preparing -> ready; 'revoked' stays reserved for the
planned admin revoke flow) along with unused KindDirect and
ErrInvalidFormat.

Sweeps: Cleanup now runs an age-based hygiene pass independent of the
byte budget — cold terminally-failed artifacts (with .part leftovers),
orphaned ready artifacts no download row references, and ephemeral web
rows older than their convenience-record lifetime (also unpinning their
artifacts and bounding GET /downloads growth). The byte budget remains
the disk quota per the limits & restrictions design.

* docs(downloads): sync API doc with v2 fixes; HEAD on file route; Android handoff

Document the contract changes from the review fixes: batch-manifest
skipped[] shape, honest subscription 'registered' semantics, season 0 =
Specials, always-array quality_presets, bytes_sent actual behavior,
ephemeral 7-day retention, header-pairing requirement, progress-delta
deletion caveat, and the ready/failed push event schema (new §9.4).
Add an Android client handoff section (§11) mirroring the Apple one,
register HEAD on /downloads/{id}/file for download stacks that probe
before ranged GETs, and add season_number to the web create-request
type. Flag the /direct-download session-token-in-URL tradeoff; a
short-lived download-scoped URL is a follow-up.

* refactor: consolidate download/progress helpers, prune dead code, gate sweeps

Behavior-preserving consolidation from the Downloads V2 review:

- appendVideoFilterArgs: one home for the burn-in/hwaccel -vf selection,
  shared by the HLS builder and the single-file prepare builder (the
  drift pattern that already bit tone-mapping once).
- userstore.ResolveProgressState: one home for the min-resume/watched
  threshold rule, replacing five identical copies across both store
  backends and the offline-sync ingest.
- Download file selection ranks resolutions via access.CompareQuality
  (adds 4320p, agrees with playback) instead of a private switch.
- writeSubtitle uses the shared subtitles.SubtitleContentType mapping.
- config.DefaultTranscodeDir replaces three '/tmp/silo-transcode'
  literals.
- Read-side quality/revision defaulting helpers removed: insertArgs plus
  the NOT NULL/CHECK schema already guarantee the invariant.
- Dead code removed: Repository.ListByUser, SubscriptionRepository.
  ListActiveBySeries, and the stale auto-register-worker comments (the
  design is client-pull; no worker exists).
- Redundant left-prefix indexes dropped from the base migrations (their
  unique indexes serve the same prefixes).
- recover()'s disk-presence sweep and the stale-row hygiene sweep run on
  startup then hourly instead of every 30s tick (both are O(cache
  size)).
- gofmt/prettier fixes for pre-existing drift in handlers/playback.go
  and pages/Profiles.tsx.

Deferred (noted for follow-ups): quality-ladder preset table collides
with the drafted download limits & restrictions design, which specifies
its own ladder helper; Download-literal construction consolidation and
the managed-identity value object remain open.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* docs(downloads): draft download limits & restrictions design

Design input for the follow-up v1 capability proposal (quality ceiling,
batch size cap, per-user quantity/bandwidth overrides). Committed with
downloads v2 because the remediation work explicitly defers the quality
ladder refactor and revocation wiring to this spec.

* fix(progress): reject malformed updated_at; clamp negative progress inputs

Review findings on #258:

- A malformed (non-RFC3339) updated_at in POST /sync/progress previously
  parsed to the zero time, which clampEventAt treated as "now" — letting a
  stale offline event win LWW as a fresh server-time write. The item is now
  rejected with a per-item error instead.
- ResolveProgressState now clamps negative position/duration before
  classification so no backend can persist negative progress through
  UpdateProgress/SetProgress.
- The online-write event_at invariant test is table-driven over both
  SetProgress and UpdateProgress, which share the same contract.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* fix(downloads): close review gaps — permission gates, file-access recheck, artifact-true manifests

Review findings on #258:

- UpdateSubscription now applies the same feature/DownloadAllowed gate as
  CreateSubscription and SyncSubscriptions; a PATCH could previously
  re-activate or widen a monitor and register managed rows after an admin
  disabled downloads or revoked the user.
- Serving download bytes (managed and ephemeral) and /direct-download now
  mirror playback's per-file authorization via catalog.FileAllowedByAccess:
  library scope and the profile's max playback quality are re-checked at
  serve time, with artifact-backed rows checked against the artifact's
  resolution (a 720p transcode of a 4K source stays servable under a 1080p
  ceiling).
- Offline manifests for remux/transcode entries now describe the prepared
  artifact (container, codecs, resolution, single selected audio track)
  instead of the catalog source file the client never receives.
- ArtifactRepository.Requeue reports ErrNotFound when the row was
  concurrently swept; ArtifactManager.Ensure recreates the job in that case
  instead of linking downloads to a dead artifact id.
- "No downloadable episodes" is a sentinel (mapped to 404
  no_downloadable_episodes) rather than a bare error that surfaced as 500.
- Subscription season_numbers are bounds-checked (0–9999) before the int32
  narrowing in the repo could silently wrap them.
- HandlePatchDownload reuses requireManaged instead of hand-rolling the
  same managed-identity checks.

QuickandGitHub cac435c4b9 Fix watch-state unwatch sync across user data and Jellyfin mappings (#179)
* Refine playback session handling and API responses

* fix(watchstate): harden completed-history visibility
2026-06-18 19:17:22 -04:00
46540dfec3 fix(progress): track resume points independently of watched state (#117)
* fix(progress): track resume points independently of watched state

Re-watching a finished item never re-entered Continue Watching: completion
latched completed = TRUE one-way, pinned position_seconds to the duration,
and the resume query filtered on completed = FALSE — so a rewatch heartbeat
could never surface the item again (and releasing the latch would have
erased the watched state clients display).

Adopt the Jellyfin invariant instead of guard heuristics:

- Completion resets position_seconds to 0 (UpdateProgress, SetProgress,
  SetProgressAt, SetProgressIfNewer, MarkWatched, MarkProgressBatch), so
  position_seconds > 0 now means "live resume point".
- completed stays a pure one-way watched latch; rewatch heartbeats re-enter
  Continue Watching through plain GREATEST/MAX while the watched flag and
  PlayCount survive (matching Plex and Jellyfin master).
- ListProgress("in_progress") keys on position_seconds > 0 in both stores;
  the SQLite store also gains the min-resume floor the Postgres store had.
- jellycompat reports Played=true with live PositionTicks during a rewatch
  (resumePositionTicks no longer zeroes played items) — the DTO shape real
  Jellyfin emits since jellyfin/jellyfin#15762.
- Web mirrors the latch (playbackProgressCache), resumes rewatches at their
  stored position, and shows progress bars on rewatched episodes.
- ABS audiobook surfaces keep today's behavior: finished books report 100%
  via the completed flag and Continue Listening still excludes them.
- Migrations reset legacy completed rows (position pinned to duration) to
  0: a Goose migration for Postgres and a user_version-gated one-time fix
  for the per-user SQLite DBs.

Replaces the guard-based approach of #109, whose restart detection
(50% fraction + 60s time gap) could never release the latch for immediate
rewatches (blocked heartbeats refreshed updated_at, re-arming the gap) and
un-watched items on position-0 heartbeats.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* fix(progress): address review — migration gate, one-way latch, missed writers/readers

Review fixes for the position-based watch-progress model:

- The per-user SQLite data fix is now migrateToV11 in the existing
  versioned runMigrations chain (schemaVersion 11). The previous
  standalone PRAGMA gate compared against 1, but existing DBs already
  sit at user_version 10, so the reset never ran for them — and the
  gate would have rewound the version. Fresh DBs short-circuit to the
  current version as before.
- `completed` is now one-way across every playback/sync writer:
  SetProgress (the RecordPlaybackStop path — stopping a rewatch below
  the watched threshold no longer clears the watched state),
  SetProgressAt, SetProgressIfNewer (both stores), and the history
  import upsert, which also stops pinning completed imports to
  position = duration. Mark-unwatched still releases the latch via
  ClearProgress/ClearProgressBatch.
- MarkProgressBatch regains its freshness guard: a delayed batch mark
  carrying an old timestamp can no longer zero a newer rewatch resume
  point (the position-reset now rides the original updated_at check).
- Catalog read paths align with the new in-progress definition
  (position_seconds > 0, completed-agnostic): smart-collection
  in_progress filter, progress sort ratio, episode progress CTE, and
  both next-up predicates.
- jellycompat derives PlayedPercentage and PlaybackPositionTicks from
  the same clamped position; a played item at rest reports 100 (as the
  old model did) while a rewatch reports its live fraction.
- ABS audiobook UpsertProgress stores position 0 on finish so finished
  books can't surface as phantom resume entries; re-listens still move
  position forward from 0 with the latch intact.
- The web optimistic cache zeroes the resume point on completion,
  mirroring the server invariant until the refetch lands.
