881c96864b feat(playback): finalize platform-neutral protocol v3 (#567)
* docs(playback): add v3 neutral-contract finalization plan

Supersedes the wire-contract sections of the 2026-07-12 v3 plan: server-owned
attempt keys, delivery-keyed negotiation without Media3 engine names, tiered
capability evidence, neutral device/output context, track/quality replan
operations, audio-only planning, and coordinated no-back-compat rollout
across server, Android, Apple, and web.

* feat(playback): make v3 attempt keys server-owned and replace engines with deliveries

Contract core of the platform-neutral v3 finalization (plan sections 3.1
and 3.2), breaking on purpose — v3 is dark and all clients move together:

- Every PlanV3 now carries plan_attempt_key, an opaque server-computed
  token clients store and echo in attempted_plan_keys; ReplanRequestV3
  gains bounded local_mutations that the replan handler folds into the
  failed plan's key. Clients never hash anything.
- KotlinName() is deleted from DeliveryV3, StreamProtocolV3 and
  SubtitleModeV3; the attempt-key canonical string now uses lowercase
  wire tokens, and PlanRecipeVersionV3 bumps to v3.3 so no key or plan
  ID computed under the old canonicalization can collide.
- EngineV3 leaves the wire: ClientPlaybackContextV3.Engines (media3_*)
  becomes Deliveries keyed original_http|progressive|hls, with
  EngineCapabilityV3 renamed DeliveryCapabilityV3. PlanV3.Engine is
  removed; the planner, subtitle policy and quirk registry re-key on
  delivery class, and the media3_only feature token is deleted.
- Validated-claim strings drop the prefix: media3_h264_decode ->
  h264_decode, media3_audio_decode -> audio_decode.
- Golden fixtures in testdata/protocol_v3 are regenerated by Go and are
  now the cross-repo source of truth.

docs/superpowers/plans/2026-07-30-playback-protocol-v3-neutral-contract.md).

* feat(playback): add v3 evidence tiers and neutral device/output context

Implement plan sections 3.3 and 3.4 of the v3 neutral-contract pass:

- ClientCodecCapabilitiesV3 gains required video_evidence and
  audio_evidence closed enums (exact | platform_attested | declared).
  Planner strictness follows the tier: exact keeps the strict decode-entry
  validation, platform_attested validates codec/resolution/bit-depth/
  frame-rate but skips profile/level matching, declared grants copy routes
  from the flat codec lists. Only exact audio evidence earns passthrough
  claims. The detailed_decode_capabilities feature token is deleted
  (subsumed by video_evidence=exact), and evidence-blocked direct routes
  carry the new evidence_insufficient_for_direct reason/warning.

- DeviceContextV3 is now platform/os_version/manufacturer/model plus a
  bounded platform_details map (<=16 entries, <=128 chars); the Android
  Build dump fields are gone. Fire TV quirks keep matching on
  manufacturer/model (brand fallback removed with the field).

- output_route_generation (int64, dual-location) becomes an optional
  opaque output_context_id string on the output context; the dual-location
  consistency validation is deleted. Attempt keys, plan invalidation,
  route events, and the planstore column follow (new Goose migration).

- Feature advertisement collapses to the top-level client_features list
  only; ClientPlaybackContextV3.Features is deleted and ReplanRequestV3
  gains an optional client_features refresh.

- PlanRecipeVersionV3 bumped v3.3 -> v3.4; fixtures re-keyed.

* feat(playback): add v3 intent replans, quality menu, and audio-only routes

Protocol v3 could only replan after a failure, so changing the audio track
or the quality still required the legacy audio PATCH and the client-recipe
transcode start — the two endpoints v3 is meant to replace. Clients also had
to own a resolution ladder to render a quality menu, and a source with no
video track was terminaled by the video/HDR gates, keeping audiobooks on the
legacy path.

Add track_change and quality_change replan operations. They carry no failure
classification and route through the existing replan transaction, so they
inherit its idempotency, capacity reservation, and staged-successor commit
for free. Because nothing failed, the previous route stays eligible: neither
the attempted-key history nor the failed-plan exclusion applies to them.

Publish the server ladder on the plan as available_qualities so the quality
menu is server-owned; the rungs come from the same resolutionLabelV3 and
ladderBitrateKbpsV3 helpers the planner itself uses, not a parallel table.

Plan audio-only sources through their own reduced route family: original_http
when the client decodes the codec, otherwise a progressive AAC conversion.
The plan advertises audio/mp4 for that remux and the transport now serves the
same value, because a declared-tier client probes the advertised MIME with
isTypeSupported before attaching a source buffer, and "video/mp4" on a stream
with no video track is exactly the mismatch that makes the probe lie.

Name the protocol's string vocabulary (dynamic ranges, transformations,
executors, validated claims, terminal reasons) as constants while touching
these lines, so the wire values have one definition.

Part of #135

* docs(playback): publish the v3 protocol contract and fix subtitle ordinals

Protocol v3 exists only as Go code today, so the Android and Apple ports have
no authority to implement against other than reading this repository. Publish
the contract as a normative document, machine-checkable schemas, and generated
golden fixtures, and fix the one place where the server's own wire output
disagreed with the ordinal space it publishes.

- docs/architecture/playback-protocol-v3.md is self-contained enough for a
  third-party client: endpoints and status codes, evidence tiers and their
  bound-matching rules, delivery classes, the timeline model, replan
  semantics, registries, track identity, plan identity, quality, and
  transformations.
- docs/design/schemas/playback-v3/ carries JSON Schemas for the five wire
  shapes plus valid and invalid fixtures, following the client-diagnostics
  layout. internal/playback/contract validates every fixture against its
  schema, so a schema that drifts from the Go types fails the Go suite.
- cmd/playbackfixtures generates internal/playback/testdata/protocol_v3 from
  the production planner. `make playback-fixtures` writes them and
  `make verify-playback-fixtures` (wired into CI) fails when they are stale.
  These files are what the client ports consume, so drift would otherwise
  surface as a playback bug on three platforms at once.

The subtitle fix: combined ordinals are one dense space over externals, then
embedded tracks, then downloaded ones, but the legacy URL builder skipped
burn-in-only tracks while assigning indices, so every track after a DVD/DVB
track was numbered one too low and resolved to its neighbour. Ordinal
assignment now lives in playback.BuildSubtitleInventoryV3 and both the plan
inventory and the legacy `subtitle_urls` shape project from it; the legacy
shape still filters burn-in-only entries but keeps each track's real index.

Part of #135

* feat(web): migrate the players to the neutral playback v3 contract

The web player was the last client still speaking the legacy start
protocol: it picked its own file version from a codec probe, posted an
ffmpeg recipe to start a transcode, PATCHed an endpoint to change audio
tracks, and derived its own quality ladder. None of that survives a
server-owned plan, and none of it produced telemetry the apps could be
compared against.

Video player: starts with a v3 request that advertises `declared`
evidence from `isTypeSupported` probes and the three delivery classes,
then consumes the returned plan for its URL, timeline, tracks and
warnings. Quality and track changes become replans (`quality_change`,
`track_change`), the quality menu renders `available_qualities` instead
of computing rungs, and playback failures emit `route-events` so web
failures land in the same diagnostics as Android and Apple. The
duration comes from `source.duration_seconds` rather than the playback
engine, and the "how was this delivered" overlay reads the plan's
delivery and server transformations instead of comparing codec strings.

Audiobook player: starts against the audio-only planner path with a
single `original` rung, and takes its seek anchor from
`timeline.player_start_seconds` so the progressive-remux route (which
anchors the stream and restarts the player clock at zero) does not seek
twice.

Server side, `disable_progress_persistence` left the wire, so the rule
it encoded is now derived. Resume state is keyed on the item, but every
part of a multipart presentation shares that key while carrying its own
file-local clock — persisting part 4's position would store "12 minutes
in" as the book's resume point. `PresentationPartTotal > 1` expresses
that directly and generalizes to multipart movies and split episodes,
and a client can no longer forget to ask or lie about it.

`useTranscodeQuality` and the legacy response types are deleted, and
`WEBTEST_KNOWN_FAILURES` loses the audiobook entry along with its fix.

Part of #135

* feat(playback)!: make v3 the only playback protocol

Protocol v3 shipped behind a flag, alongside the legacy start path it was
designed to replace. Running both meant every planner change had to be made
twice, in two shapes that disagree about who decides the route: the legacy
body carried a decision the client had already made, while v3 asks the server
to make it. This deletes the legacy half.

Removed:

- `handleStartPlaybackLegacy` and its request/response bodies. The
  `POST /playback/start` route stays, but the protocol-version dispatch
  envelope is now a strict v3 decode — a body that does not declare
  `protocol_version: 3` gets `426 client_upgrade_required` so an outdated app
  can render a clear "update required" state instead of misreading a plan.
  Deliberately not a `400`: the request may be well-formed for the protocol it
  was written against.
- `POST /playback/transcode/start`, superseded by the `quality_change` replan
  operation, and `PATCH /playback/{session_id}/audio`, superseded by
  `track_change`. Both mutated a session without re-planning.
- The shadow planner and both rollout settings rows. With v3 the only
  protocol, `playback.protocol_v3_enabled` would mean "no playback at all";
  `playback.protocol_v3_shadow_enabled` gated a comparison against a path that
  no longer exists. `409 protocol_disabled` on route-events goes with them, and
  capability `enabled` is now constant `true` (the field stays — clients
  feature-detect against it).
- Version-selection helpers in `internal/playback/resolver.go` that only legacy
  start reached. `Resolve`/`ClientCapabilities`/`PlayDecision` stay: downloads
  consumes them. `internal/jellycompat` has its own resolution surface and is
  untouched.

Behaviour the legacy handlers owned and v3 now owns explicitly: series version
and audio-track preferences are persisted on start and on a `track_change`
replan (not on failure recovery, whose forced route is not a user choice); an
omitted `start_position` resolves to the profile's saved resume point; and an
omitted audio track resolves through the series preference, the profile audio
language, then the library override. Both are settled before planning, because
the plan's timeline is cut at the start position. Spec §2.2 documents this as
"omission is a request, not a default".

The encode-target clamp that lived in the deleted transcode handler is already
enforced in the planner, twice — `availableQualitiesV3` omits rungs at or above
the source height, and the encode path clamps `targetHeight` to it.

Unchanged: progress, stop, HLS manifest and segment delivery, the realtime
control socket, stream tokens and restart reconstruction, watch together,
downloads, jellycompat.

Every removal is recorded in the pre-lock removals table in
docs/architecture/v1-scope.md.

Part of #135

* fix(scanner): stop recording embedded cover art as a video track

ffprobe reports embedded cover art as a video stream carrying
disposition.attached_pic. convertProbeData appended every "video" stream
to VideoTracks without consulting isMainVideoStream, the predicate that
already existed for duration decisions, so the picture was persisted as a
playable track. That misreports the file twice:

  - An audio file with a cover picks up a video track, so it no longer
    satisfies MediaFile.IsAudioOnly and the v3 planner routes an
    audiobook through the video path instead of planAudioOnlyV3.
  - When the picture is ordered ahead of the real stream, the flat
    codec_video/resolution/hdr columns describe the poster: a 954x720
    h264 episode was stored as mjpeg 480x480.

Filter attached_pic streams out of the track loop. The guard is the
disposition flag, not the codec name, so a genuine MJPEG video is still
probed as video — the library has one.

Already-probed rows self-heal on the next playback: NeedsCriticalProbeRepair
already reprobes tracks missing color_range, which covers 21 of the 23
affected rows, and applyProbeData overwrites VideoTracks wholesale. The
remaining two need a rescan; nothing persisted records attached_pic, and
keying repair off still-image codec names would reprobe the genuine MJPEG
file on every playback forever.

Part of the playback v3 neutral-contract work: it is what lets Android
drop AUDIOBOOK_COVER_ART_CODECS, which fabricated decode support the
client cannot honestly claim under video_evidence: "exact".

* fix(playback): publish subtitle URLs even when playback starts with subtitles off

The v3 plan's subtitle inventory is the authoritative track list a client builds
its subtitle menu from, but the handler only rewrote it with session-scoped URLs
when a track was actually selected. A start or replan that resolved to
`subtitle.mode: "off"` therefore returned the planner's URL-less inventory, so a
client whose picker reads the inventory had a menu it could not fetch anything
from. The Cast path hits this every time: it starts with subtitles off and needs
the receiver's text tracks up front.

attachSubtitleArtifactV3 now scopes and publishes the inventory unconditionally
and gates only the artifact stamping on the selection. Spec §8 records that the
`url` on a sidecar entry does not depend on the current selection.

* fix(playback): harden v3 replan, transcode, and quality-ladder edge cases

Review remediation for the neutral v3 cutover, server side:

- A failed replan no longer overwrites the durable StartResponse with a
  terminal or advances the replan request ID; an idempotent start replay
  of a still-healthy session returns the original plan.
- SoftwareVideoDecode is now derived inside the transcode layer from
  source facts (codec/profile/bit depth) carried on TranscodeOpts, so
  jellycompat, downloads, recipe-card reconstruction, and transcode
  nodes get the High10 software-decode fix, not just the v3 handler.
  video_to_h264 recipe version bumps to 2 so mixed-version node pools
  that would silently drop the flag fail validation instead.
- Local transport startup shares the 30s ManifestStartupTimeout; a
  timeout with the process still running stays retryable and is no
  longer persisted as a durable terminal against the attempt.
- Sparse replan bodies (failure_recovery et al) no longer reset a
  user-selected quality preference to auto; the empty-value guard now
  covers every operation.
- availableQualitiesV3 publishes no fixed rungs when the source height
  is unknown, keeping the no-upscaling ladder contract.
- The proxy remux path serves audio-only fMP4 as audio/mp4 via a new
  additive AudioOnly token claim, matching the integrated path.
- Plain text subtitle sidecars accept any requested extension again
  (served as VTT), restoring the permissive v1 behavior; ASS and bitmap
  handling is unchanged.
- The 4K-disallowed terminal message discloses when a lower-resolution
  alternate exists but was pinned away by quality "original".

* fix(web): keep playback alive through failed replans and honest audio claims

Review remediation for the neutral v3 cutover, web player:

- A failed or refused replan no longer unmounts the player: the fatal
  error screen is reserved for loads with no adopted plan, and replan
  failures surface through the existing non-fatal replanError path.
- changeQuality rolls its optimistic preference back when the replan is
  refused or errors, so a failed switch is not silently applied by the
  next unrelated replan and the menu shows the real active rung.
- The capability probe now tests mp3/vorbis codecs and mp3/flac/ogg
  containers (MediaSource with a canPlayType fallback), restoring
  direct play for mp3 audiobooks instead of per-part AAC re-encodes.
- Reanchor seeks issued while a replan is in flight coalesce and run
  when it settles instead of being silently dropped with the scrubber
  pinned to a phantom position.
- Subtitle refresh/translation replans use the resume anchor while the
  media element has no metadata, so a subtitle_ready broadcast during
  startup no longer restarts a resumed stream at 0:00.
- An exhausted failure-recovery chain sets a visible error instead of
  returning silently.

Part of #135.

* fix(playback): accept video-only and VP9 probe metadata

Treat audio and video probe completeness independently so legitimate video-only assets converge without repeated ffprobe repair. Allow unknown codec profile/level metadata to fall through to server adaptation while preserving exact direct-decode constraints.

Fixes #574

* fix(playback): address protocol v3 review findings

* fix(playback): harden lease and probe repair decisions

* fix(playback): close remaining v3 review gaps

* fix(playback): recover failed transcode starts

* fix(playback): address remaining review-bot findings on v3 replan and audio planning

Server:
- The deferred replan lease release is bounded by a 3s timeout so a
  saturated pool or DB outage cannot wedge a handler goroutine that
  holds the per-session store lock on an uncancellable context.
- planAudioOnlyV3 honors the request bandwidth cap: an over-cap source
  skips the original_http direct route and converts to AAC with the
  same bandwidth_cap_applied warning and decision reason the video
  ladder uses. Unknown source bitrate never triggers the cap.
- A copy-audio progressive plan rejected only by a per-delivery
  audio_decode_codecs subset retries as an AAC conversion instead of
  returning adaptation_unavailable, and the AAC recipe respects the
  delivery's max_channels.

Web:
- failure_recovery replans issued while another replan is in flight
  queue (superseding a pending seek reanchor) instead of being
  silently dropped with the fatal overlay already suppressed.
- A terminal response to a fresh non-preserving start clears the
  previous plan and stops its session, so episode navigation cannot
  keep rendering the prior item under the new title.
- A refused recovery replan for a transport-dead plan surfaces the
  error and re-arms the plan failure key, so transient recovery
  failures no longer strand an endless spinner; the audiobook player
  gets the same guard reset.
- A track-less subtitle_translation_completed hands off to the
  refreshed persisted track once the inventory settles, clearing the
  live overlay, instead of pinning the synthetic live track forever.

203a18ae83 feat(observability): OpenTelemetry logs+traces with secret redaction and slog standardization (#290)
* feat(observability): OpenTelemetry logs+traces with secret redaction

Part of #265. Adds opt-in OpenTelemetry (logs + traces) alongside the existing
stderr + opslog pipeline, plus secret redaction on all sinks. Default-off: with
no OTEL_* / SILO_OTEL_ENABLED config, behavior is unchanged.

Bootstrap (internal/telemetry):
- Setup() builds one shared resource, a TracerProvider (parent-based trace-id
  ratio sampler), a LoggerProvider, and the W3C TraceContext+Baggage propagator
  from env. It installs NO MeterProvider — metrics stay on Prometheus, and the
  built-in no-op global MeterProvider keeps the trace instrumentation libs from
  double-emitting. Shutdown is deferred with a flush timeout.
- Logs are bridged via otelslog fan-out (slog.MultiHandler), level-gated by the
  shared LevelVar and best-effort so a failing collector can't break the console
  or DB branches. stderr + opslog stay untouched.

Secret redaction (internal/logredact):
- A slog.Handler masks secret-keyed attributes (password, token, api_key,
  authorization, cookie, ...) — including .With-bound attrs, nested groups,
  secret-keyed group subtrees, and values behind a LogValuer — on the console
  and OTLP sinks, with a no-op fast path when a record has no secret keys.
  opslog.shouldRedact delegates to logredact.SecretKey so all sinks share one
  marker list.

Rotation is infra-managed (no custom file sink): container runtime for stderr,
collector/backend for OTLP, opslog partition-pruning for the DB. Documented in
docs/architecture/observability.md.

Verification: go build ./..., go vet, gofmt -l — clean; go test
./internal/telemetry/ ./internal/logredact/ -race pass.

AI-use disclosure: implemented with AI assistance (Claude Code), including
adversarial reviews that hardened the bootstrap and fixed two redaction leak
paths; reviewed by the author.

* refactor(observability): slog context+component sweep, sloglint gate (phase 3)

Part of #265. Builds on the OTel bootstrap + redaction commit.

Standardizes every log call site onto the context-carrying slog variants so
records correlate with the active OpenTelemetry trace, and locks the standard
in with a machine gate so future code (human- or AI-authored) can't drift back.

- Call-site sweep: converted the remaining slog.<Level>(...) calls to the
  slog.<Level>Context(ctx, ...) form wherever a context.Context is in scope
  (background/init calls with no ctx are left as-is), across 183 files. Applied
  via a type-aware AST codemod. Log levels and message strings are preserved
  verbatim; a component attr (canonical per-package name) is added to direct
  package-level slog calls. Bound-logger calls keep their existing .With
  bindings. The main.go and telemetry package conversions rode with their file
  in the previous commit to keep each file within a single commit.
- Enforcement (.golangci.yml): enable sloglint with context=scope, static-msg,
  key-naming-case=snake, no-mixed-args. After the sweep all four report zero
  violations repo-wide (tests included), so make lint / CI now blocks any
  regression to the non-context form. The gate ships with the sweep because it
  cannot be green until the legacy sites are converted.

Metrics remain on Prometheus; no behavior change to /metrics or Grafana.

Verification: go build ./..., go vet ./..., gofmt -l — clean; sloglint (all 4
rules) 0 violations repo-wide; log levels verified unchanged.

AI-use disclosure: implemented with AI assistance (Claude Code), including the
codemod; reviewed by the author.

* fix(observability): honor per-signal OTLP protocol and secret WithGroup names

Two Codex review findings on PR #290:

- telemetry: OTEL_EXPORTER_OTLP_{TRACES,LOGS}_PROTOCOL now override the
  generic OTEL_EXPORTER_OTLP_PROTOCOL per signal, so mixed collector
  setups (e.g. HTTP logs + gRPC traces) build the right exporter.
- logredact: entering a group whose name is secret-bearing (e.g.
  WithGroup("authorization")) now masks every leaf in that subtree,
  matching how slog.Group("authorization", ...) is masked as a whole.

* fix(observability): address review feedback on telemetry bootstrap

- Telemetry setup failure no longer kills boot: Setup returns usable
  no-op providers alongside the error and main logs and continues with
  telemetry disabled, honoring the best-effort contract.
- Honor OTEL_TRACES_SAMPLER (always_on/off, traceidratio, parentbased_*
  variants); unsupported values fall back to parentbased_traceidratio.
- Attach node identity as semconv service.instance.id instead of the
  non-semconv node.name.
- Rename opslog retention-scope log attrs to target_component/target_level
  so they no longer collide with the canonical component routing key, and
  tag those lines with component=opslog.
- Fix stale levelGated comment casing; use WarnContext in the telemetry
  shutdown defer; document the LogValuer double-resolve on the redaction
  slow path.

* build(deps): add OPA v1.18.2 SDK for the policy engine

Pulls github.com/open-policy-agent/opa v1.18.2 (policy engine core for
the upcoming internal/policy subsystem) and the transitive upgrades go
mod tidy applied (otel 1.44, grpc 1.81.1, prometheus/common 0.67.5).
Full build verified.

* feat(policy): add OPA engine core, vendor scope policy, and parity suite

New internal/policy package (dead code — nothing wires into request paths
yet): prepared-query Engine with 25ms eval timeout and fail-closed decode,
typed PDP.ResolveViewerScope, go:embed vendor bundle, capabilities lockdown
for future admin-authored Rego, and vendor scope.rego reproducing
access.Resolver.Resolve (library intersection, disabled-library handling,
quality/rating ceilings) with a narrowing-only silo_custom.scope.override
extension hook.

Parity proven by 1368 dual-execution subtests against the real
access.Resolver, including the nil-vs-empty AllowedLibraryIDs battery and
quality/rating variation; rank tables are test-pinned to internal/access.
Rego unit tests run via opa/v1/tester inside go test. Bench:
~106µs/op per scope decision incl. input marshaling.

Also restores the OPA requirement to go.mod (the earlier deps commit ran
go mod tidy before any import existed, so tidy dropped it).

Implementation drafted by Codex (GPT-5.5) via codex exec; reviewed,
corrected (quality.allowed raw-file-rank divergence), and verified here.

* feat(policy): add policy document store, foundation schema, and compile-check

policy_foundation migration: policy_documents (one enabled doc per domain
via partial unique index — two enabled docs would define override twice
and conflict at eval), immutable policy_document_versions, single-row
policy_generation counter, and the partitioned policy_decisions log table
(daily range partitions, no FK, denial partial index).

PolicyStore: transactional version numbering (FOR UPDATE), activation
that verifies compiled_ok and bumps the generation in the same tx,
enable/disable with typed ErrDomainAlreadyEnabled, and a delete guard for
documents with an active version. CompileCheck sandboxes admin Rego:
locked capabilities (no http.send/net.*/opa.runtime), enforced
silo_custom.<domain> package path, vendor+stub layering, 2s budget,
structured row/col errors. Engine gains NewEngineWithCustom /
NewEngineFromStore with WARN-and-skip for invalid custom rows.

DB-backed tests verified against a migrated Postgres (concurrent version
numbering, atomic generation bumps, activation guards).

Implementation drafted by Codex (GPT-5.5) via codex exec; reviewed and
verified here (domain constants extracted).

* feat(policy): add policy System lifecycle with hot reload and cross-node invalidation

policy.System owns one long-lived Engine and reloads it in place when
policy documents change: EventPolicyChanged on the existing ChannelAdmin
bus (new cache event constant) plus a 60s generation-poll fallback for
Redis-less deployments, with a generation-consistent snapshot read.
Vendor compile failure is startup-fatal; store/custom failures degrade
to vendor-only and the poll loop heals them; runtime reload failures
keep the last known-good engine. NotifyChanged gives the future admin
handlers synchronous local reload + cross-node publish.

Wiring: constructed in integrated/api modes only, PolicySystem field on
api.Dependencies (unused by routes yet), policy.eval_timeout_ms setting
(hot-reloaded via configWatcher.OnChange; default 25ms). Verified by a
full server boot smoke and DB-backed convergence tests (event + poll
paths, degraded boot, last-known-good).

* feat(policy): add async decision logging with sampling, retention, and query repo

DecisionLogger batch-inserts each node's policy decisions straight to
the partitioned policy_decisions table via a non-blocking buffered
channel (drop-and-count on overflow — logging never adds latency to or
fails a decision). Scope decisions sample 1-in-N (default 50, setting
policy.decision_log_scope_sample_rate); denials and eval errors always
log; input/result JSON samples only at policy.decision_log_verbosity=

* feat(api): add admin policy management API and capability endpoint

/api/v1/policy/capability (authenticated feature detection) plus the
acting-admin /api/v1/admin/policy surface: vendor Rego viewer, document
CRUD with the one-enabled-per-domain conflict mapped to 409, immutable
version creation (compile-checked; failed versions persist as audit
history with structured row/col errors and can never activate),
activate/rollback with synchronous reload + cross-node invalidation via
System.NotifyChanged, stateless validate, throwaway-bundle simulate
(never touches the live engine, never logs decisions), and
cursor-paginated decision-log queries. Routes mount only when the
policy system is wired, keeping proxy/transcode modes untouched.

Implementation drafted by Codex (GPT-5.5) via codex exec; reviewed and

fmt.Sscanf with strconv).

* feat(web): add /admin/policy workspace with Rego editor, simulate, and decision log

New Policy admin page (System nav group): documents list with
one-enabled-per-domain conflict handling, CodeMirror 6 Rego editor
(hand-rolled StreamLanguage mode) with server compile issues rendered as
inline lint diagnostics, explicit Save-version vs Activate flow with
confirm, read-only vendor module viewer, simulate panel with seeded
example inputs, version history with rollback, and a cursor-paginated
decision-log browser. Capability-gated via /policy/capability. Adds the
three decision-log settings to Log Retention. First code-editor
dependency in web/ (@uiw/react-codemirror + @codemirror/*), decided in
the design spec.

* feat(policy): make OPA authoritative for viewer scope resolution

policy.ViewerResolver implements the ViewerResolver interface backed by
PDP.ResolveViewerScope and replaces access.Resolver at all five
construction sites: router viewer middleware, notifications scopes, the
reconciler, jellycompat's scope filter, and the ABS resolver (which now
accepts a pre-built resolver, preserving its PIN-at-login semantics).
PIN/profile-token verification and disabled-library loading are
extracted into shared exported helpers used by both implementations, so
the legacy resolver stays compiled as the parity reference with
identical behavior. The adapter lives in internal/policy (which already
depends on internal/access transitively) — direct typed PDP calls, no
new import cycle. Sites without a policy system (proxy modes, bare test
routers) keep the legacy resolver until the cleanup phase.

Verified: full test suite green (jellycompat TestBeginWebOperation* and
one playback GPU test are pre-existing failures, confirmed identical on
main), 1368-case parity suite, dedicated ViewerResolver parity/PIN/
nil-vs-empty/fail-closed tests, and a full server boot smoke.

Implementation drafted by Codex (GPT-5.5) via codex exec; a first-pass
reflection-based adapter was rejected and reworked into the typed
in-policy adapter; reviewed line-by-line and verified here.

* feat(policy): make OPA authoritative for acting-admin and permission gates

vendor/permission.rego reproduces the acting-admin rule (admin role +
primary-profile-or-none), HasEffectivePermission semantics for
marker_edit, and the metadata-curation rule including the subtle
admin-past-refused-bypass case that requires the explicitly ASSIGNED
permission. Policy-backed middleware in policy_gates.go keeps all Go-side
lookups (declared-profile primary check, item->library resolution, the
404-on-unknown-item path) and preserves the legacy status/body taxonomy
exactly — proven by dual-execution middleware tests that run every
scenario through both implementations and assert byte-equal responses.
Permission decisions always log (allowed flag populated); simulate and
the capability endpoint gain the permission domain automatically via the
domain registry. Router swaps behind single constructor choice points
with the legacy gates retained for policy-less wiring.

* feat(policy): make OPA authoritative for download and playback admission decisions

vendor/action.rego decides download eligibility (downloads enabled +
user allowed), download-transcode eligibility (transcode enabled + user
allowed + artifacts available), and playback admission (stream/transcode
counts vs limits, zero = unlimited), with a tightening-only
silo_custom.action override that can also clamp a quality ceiling (never
widen — merged via quality.min). Go keeps everything stateful: config
loading, preset-ladder enumeration, and live session counting.

Downloads consult an optional ActionDecider (nil = legacy logic) mapped
back to the existing sentinel errors and capability response. Playback
gains a minimal AdmissionDecider hook at the exact point of the legacy
limit comparison: counts snapshot under the session mutex, PDP evaluated
OUTSIDE the lock, then revalidated under lock before insert (retry on
count drift) — no admission ever decided on stale counts and no eval
under the mutex. Deny reasons map to the legacy ErrTooManyStreams /
ErrTooManyTranscodes sentinels, pinned by tests.

Parity: combination tables driven against the real PresetsFor /
ensureTranscodeAllowed / SessionLimits math; full suite green (known
pre-existing jellycompat flakes only).

Vendor policies index required input fields directly, so a hand-written

* refactor(web): redesign the policy workspace around the decision pipeline

The first-pass UI was structurally generic: a five-column document table
squeezed beside the editor, three equal-weight action buttons with
hidden preconditions, raw version IDs, and jargon copy — nothing taught
the model. The page now teaches it:

- A pipeline strip states the mental model up front: Silo decides the
  baseline -> your overrides narrow it -> every decision is logged. Tabs
  renamed to Overrides / Baseline / Decision Log (ids stay stable for
  bookmarked URLs).
- The document table becomes one card per domain (Library visibility /
  Admin & permissions / Downloads & playback) with plain-language
  descriptions, example rules, status pills (Live vN / Draft / Disabled),
  inline creation, and the enable kill-switch in place.
- Selecting an override drills into a full-width editor with a visible
  lifecycle rail (Draft -> Validated -> Saved -> Live) and one contextual
  primary action per step; the unedited live source shows no actions
  until edited. Version comments appear only at the save step.
- Simulate is reframed as 'Test before going live' with a human verdict
  chip (Allowed / Denied — reason / ceiling summary) above the raw JSON;
  internal generation counters no longer surface.
- History uses 'Make live' with plain go-live copy; authors read
  'User N'; the baseline tab explains that upgrades never touch
  overrides.

Hand-written redesign (no Codex); verified via vitest, tsc, eslint,
prettier, and a production build.

* refactor(web): present the policy baseline as readable rules, not raw Rego

The Baseline tab dumped five Rego modules into read-only editors. It now
leads with what the rules actually do: one card per domain with
plain-language statements of the shipped behavior and a note on what an
override may change, plus content-rating and playback-quality tier
ladders parsed live from the lib module sources (so the tiers shown are
the ones the server enforces, not a hardcoded copy). The Rego source
stays one click away behind a per-module accordion and remains the
stated source of truth; unrecognized modules fall back to source-only.

* docs(policy): add access-groups design addendum

Groups with permission toggles become the everyday admin surface; the
Rego editor is demoted behind policy.editor_enabled (default off).
Restriction-only composition: group grants are an upper bound, per-user
settings tighten further — same rule as the existing account/profile
merge, one layer up.

* feat(access): add access groups — group defaults with restriction-only composition

New access_groups table + users.access_group_id (one group per user, NULL
= today's behavior). Group grants are an upper bound composed with the
user's own settings by strictest-wins rules — library intersection,
MinQuality, AND'd booleans, strictest positive stream/transcode limits,
permission-mask intersection, and a requests toggle gating CreateRequest.
The merge happens in Go (access.ApplyGroupPolicy /
EffectivePolicyForUser) before policy inputs are built, so vendor Rego,
the parity suites, and the decision log are untouched; every enforcement
surface (viewer scope in both resolvers, permission gates, downloads,
playback admission, requests) consumes the effective policy and fails
closed on provider errors. Changing a group's quality ceiling bumps its
members' access_policy_revision, mirroring the per-user rule.

Additive admin API: /admin/access-groups CRUD with member counts;
PUT /admin/users/{id} + user DTOs gain access_group_id.

Also demotes the Rego editor: policy.editor_enabled (default off,
hot-reloaded) drives the capability endpoint's editor_available and
403-gates editor endpoints while the engine and decision logging keep
running.

* feat(web): add Access Groups admin page and gate the policy editor

New /admin/access-groups: a card grid summarizing each group (member
count + key restrictions), drilling into an editor that reuses the same
LibraryAccessSelector and quality presets as the user editor, with
toggles for downloads/transcoded-downloads/requests, concurrent-stream
and transcode limits, and a permissions mask (all-assignable by default,
narrowable to specific permissions). Delete warns how many members fall
back to the built-in defaults. Copy states the composition rule up front:
a group grants the most a member can do; their own restrictions still
apply on top.

The user editor gains a Group picker and read-only row; the Policy nav
entry is now hidden unless the capability reports the editor enabled.
Plumbing (types, hooks, user-editor picker, nav gating) drafted by Codex
(GPT-5.5); the Groups page hand-built. Verified: 25 tests across the
touched suites, tsc, eslint, prettier, and a production build.

* feat(access): seed a Default Group and auto-assign newly created users

Adds access_groups.is_default with a partial unique index (one default
at most — the profiles is_primary pattern) and seeds a permissive
'Default Group' whose ceiling is a no-op, so assignment never changes
anyone's effective access until an admin edits it. The seed is guarded
against pre-existing defaults and name collisions; the Down migration
only removes the row if it is still untouched.

Assignment happens at the single INSERT INTO users choke point
(UserRepository.Create): when no explicit group is given, access_group_id
is filled by a scalar subquery on the default flag — NULL when no default
exists. Every creation path (setup, signup, invites, OAuth, admin create)
is covered by construction. Setting a new default via the API atomically
clears the previous one in the same transaction.

Deleting or unsetting the default is legal: new users then start with no
group, which is pre-feature behavior.

choke-point subquery reviewed line-by-line here.

* feat(access): ship the Default Group with house-rule ceilings

Seed values per product decision: 5 concurrent streams, 5 transcodes,
transcoded downloads off, and a permission mask of marker_edit only

Down guard matches the new values so it still only removes an untouched
seed row. Only newly created users are affected; existing users are
never assigned.

* feat(access): retire per-user defaults — the Default Group is the sole default policy

Removes both legacy 'user defaults' mechanisms now that the seeded
Default Group owns new-user policy:

- users.max_streams / max_transcodes column defaults drop from 6/2 to 0
  (= unrestricted at the user layer), so group ceilings apply to new
  signups/invites/OAuth users instead of fighting stale per-user
  numbers. Existing rows keep their stored values — nobody is silently
  uncapped on upgrade.
- The dead defaults.max_playback_quality / defaults.max_profiles
  settings validation goes away with its only writer (the User Defaults
  dialog, removed on the web side).

* feat(web): replace the User Defaults dialog with group-governed creation

The Users page's 'User Defaults' dialog (defaults.* server settings)
duplicated what access groups now do properly, and its values were only
ever form prefill — no backend path applied them. The button now links
to Access Groups, and the create-user form seeds unrestricted user-layer
values (0 streams/transcodes, any quality, downloads allowed) so the
member's group governs; per-user fields remain for tightening individual
users.

* feat(access): migrate existing non-admin users into the Default Group

Existing users join the seeded Default Group on upgrade so one policy
source governs the whole instance. Their per-user limits still holding
the retired 6/2 column defaults are normalized to 0 in the same
statement so the group's ceilings actually apply; deliberately
customized values are preserved. Admin accounts stay ungrouped —
scope/action decisions are role-blind, so grouping an admin would cap
the server owner on upgrade.

* fix(access): keep admins out of the Default Group and treat group moves as policy changes

New-user creation now mirrors the migration's admin exclusion: the
default access group is only auto-assigned to non-admin roles, so a
fresh server owner no longer inherits the starter group's transcode
denial and stream caps.

Changing a user's access group now bumps access_policy_revision (the
group carries permissions, quality, and limits, exactly like the
per-user fields that already bump it) and triggers admin session
revocation when the group actually changes.

* fix(policy): enforce marker_edit through the PDP on marker write routes

The Rego permission policy owned marker_edit but no Go caller ever
consulted it: PUT/DELETE /markers went through a handler-local check
that short-circuited admins and read only the user's own permissions,
so group permission masks and custom policy overrides were ignored.

Marker writes are now gated by router middleware like the other
permission surfaces: a PDP-backed RequireMarkerEdit that evaluates the
group-merged effective permissions (plus the legacy variant for
proxy/test wiring without a policy system). The handler-local check and
its user loader are gone.

* fix(downloads): assert device/quality policy facts and honor the quality ceiling

The download_transcode action check hard-coded an empty device ID and
never asserted the requested quality, and no caller consumed
ActionDecision.QualityCeiling — custom download policies keyed on those
inputs were silently ineffective.

Resolve now threads the request's device ID and requested quality into
the action input, and a returned quality ceiling downscales the
prepared transcode target (the ceiling applies to what is served,
matching the serve-time rule in serveDownloadBytes). FileQuality and
the content-rating pair stay intentionally empty for downloads —
documented on downloadActionInput: those ceilings are enforced against
the served artifact by the scope-derived access filter, and asserting
the source's quality would wrongly deny capped transcodes.

* test(access): align the default-group seed assertions with the migration

The DB test still asserted the earlier no-op seed (transcode allowed,
unlimited streams/transcodes, null permissions); the shipped migration
seeds transcode denied, 5/5 limits, and marker_edit-only permissions,
so the test failed on any database with the migration applied.

* fix(policy): lock the Rego sandbox by builtin purity and bound compile work

Exclude every nondeterministic builtin from the admin sandbox instead of
denylisting names, so OPA upgrades cannot silently expose impure builtins
while pure helpers like net.cidr_contains stay usable. Apply the same
capabilities to the runtime engine, cap concurrent compile checks, and
reject oversized sources before they reach the uncancelable compiler.

* fix(policy): require literal booleans in vendor override and input checks

Bare object.get truthiness treated any non-false value as satisfied, so a
malformed override 'allowed' value could fail to tighten a base grant and
hand-crafted simulate input could flip flag predicates. Compare against
literal true so anything else denies.

CleanupDecisionLogsOnce now returns the first error alongside the deleted

* fix(access): nil-guard the downloads user and restore the ABS legacy resolver

effectiveDownloadUser dereferenced policy state before its nil-user check,

The policy write endpoints (create document/version, set enabled,
validate, simulate) decoded JSON bodies without a size limit, so an
oversized payload buffered fully in memory before CompileCheck's

decodePolicyRequest helper that wraps the body in http.MaxBytesReader
and returns 413 with the repo's standard too_large error shape.

* fix(access): forbid deleting or demoting the default access group

Deleting the default group (or unsetting its is_default flag) left the
server with no default: new non-admin users were then created ungrouped
with max_streams/max_transcodes of 0 — unlimited — because the legacy
per-user column defaults were retired in favor of the group's ceilings.

The store now rejects both operations with ErrDefaultGroupRequired
(mapped to 409); promoting another group remains the supported way to
move the default, and atomically clears the previous one. The admin UI
disables the delete button and the default toggle on the default group
and explains the promote-another-group flow.

* fix(web): keep unsaved policy drafts when a newer version activates elsewhere

The editor state was keyed on the active version's id/sha, so a
background refetch after another admin (or another tab) activated a
version remounted the editor and silently discarded the dirty draft.

PolicyEditorPanel now pins the seed it is editing against and only
adopts an incoming seed when nothing can be lost: the editor is clean,
the draft already equals the incoming source (the same-admin activate
flow), or the selection moved to a different document. Otherwise the
pinned editor stays mounted and an inline notice offers an explicit
"Load live version" action.

* fix(policy): fail reloads on invalid custom sources and surface degraded/apply state

A stored custom source that stops compiling used to be silently skipped on
reload: the bundle widened to vendor-only for that domain while the generation
reported fully applied. Reload is now strict — a bad enabled source fails the
reload and the last known-good engine keeps serving. Boot keeps its vendor
fallback for availability, but skips are recorded on the engine and exposed
(with store-outage reasons) through System.DegradedState and additive
degraded fields on GET /policy/capability. Activate/SetEnabled re-run
CompileCheck instead of trusting the stored compiled_ok flag.

Mutation endpoints also no longer conflate persistence with live apply:
activation/enable responses carry additive applied/failed_step/
loaded_generation fields and return 202 when the store change persisted but
the local reload failed.

Addresses review findings C1, C2, and the degraded-signal gap (6.1).

* fix(policy): type deny reasons across the contract and enforce profile_verified

Deny handling used to branch on exact free-text reason strings in three Go
consumers, and playback reported ANY unrecognized reason — including custom
override free text and engine failures — as a stream-limit error. Decisions
now carry a stable reason_code (custom overrides always get custom_denial);
downloads, the metadata-curation gate, and playback admission switch on codes,
with a new ErrPlaybackNotAllowed -> 403 playback_not_allowed mapping for
non-limit denials. Rego tests pin every vendor code.

The scope contract's tighten-only profile_verified output was also emitted but
never consumed; a policy revocation now surfaces as ErrProfileUnverified (403
profile_unverified) instead of silently proceeding.

* fix(catalog): close the dual-library disabled-scope bypass in direct item authorization

EnsureAccessible, EnsureAccessibleIDs, and FilterAccessibleContentIDs gated
library access with allow/deny predicates over a single joined
media_item_libraries row, so an item linked to BOTH a passing library and a
disabled one satisfied the disabled check via the passing row — a direct-ID
bypass of disabled-library scope on the detail, media-file, playback, and
download paths. All library access predicates now share one helper
(libraryAccessConditions) emitting independent EXISTS / NOT EXISTS subqueries,
the semantics GetByIDsWithAccess already used, including the orphan-item
membership guard for disabled-only scopes. SQL-shape tests pin every builder
and a DB-gated regression test covers the dual-library item end to end.

buildFilterAccessibleContentIDsSQL, which the review did not flag).

* fix(downloads): serialize quota check and row creation under a per-user advisory lock

The concurrent-download quota was check-then-insert with nothing serializing
the pair: parallel creates could all observe free quota before any row
existed, bypassing the cap and stacking artifact encode jobs. All four
check->insert spans (ephemeral original, artifact-backed, series batch,
managed batch) now run inside Repository.WithUserQuotaLock — a
pg_advisory_xact_lock keyed by user, so the serialization holds across nodes.
The artifact path keeps the limiter-before-Ensure ordering (a rejected request
must not leave an encode job behind) by holding the lock across Ensure.
Managed-entry replacement stays quota-exempt and lock-free. A DB-gated
barrier test races 8 creates against a cap of 1.

* fix(downloads): assert served quality at create time for original and remux downloads

Direct-original and remux downloads serve the source resolution unchanged, but
create-time policy checks left file_quality empty — an over-ceiling source
registered a row serveDownloadBytes could never satisfy. Resolve now runs a
final download action check with FileQuality populated on those two paths
(capped transcodes keep the ceiling-on-artifact behavior), a custom override
ceiling below the served resolution denies, and quality_ceiling_exceeded maps
to ErrQualityUnavailable. The ActionInput contract now documents exactly when
file_quality and the rating facts are supplied so custom policy authors are
not misled.

A custom scope override that exceeds the 25ms eval budget compiled fine,
activated fine, and then converted to 500s on every authenticated request —
server-wide lockout authored in the admin editor. Activation and enable now
run GuardEvalCost: the candidate source is evaluated on a throwaway engine
against a canned representative input under the live budget, and a source
that cannot complete is rejected 422 with ErrPolicySlowEval before it goes
live. Runtime timeouts keep failing closed but now carry a distinct
ErrPolicyEvalTimeout sentinel, an Error log, and a per-engine counter exposed
as eval_timeouts on GET /policy/capability so intermittent near-budget
policies are attributable.

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.

* 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.

* 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.

* 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.
