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.

* 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.

567cdd1a15 feat(playback): balance transcode sessions across multiple GPUs (#425)
* feat(playback): balance transcode sessions across multiple GPUs

playback.hw_device now accepts a comma-separated render-device list (e.g.
"/dev/dri/renderD128,/dev/dri/renderD129"). Each transcode session resolves
the list to one concrete device at spawn — the present device with the
fewest active GPU sessions, ties keeping list order — and holds that device
for its whole lifetime (seek/audio restarts reuse it); the reservation
releases on session shutdown, idempotently, including early spawn-failure
paths. Software-accel sessions never reserve, so they cannot skew the
balance.

A single configured value keeps the historical pass-through contract and an
empty value still auto-detects, so existing deployments are unaffected.
PickRenderDevice is list-aware too, picking least-loaded without reserving,
which lets the non-session consumers (chapter thumbnails, download
artifacts, transcode nodes) spread load best-effort when given a list.

Motivation: hosts with two identical media GPUs (e.g. dual Arc A310)
previously pinned every session to one device while the second sat idle.

* feat(admin): GPU device picker for playback hw_device

The hw-accel detection endpoint now reports render_device_details — each
render device with a human label derived from its sysfs PCI vendor/device
ids ("Intel GPU (0x56a6)") — and the Playback settings page renders them as
per-device toggles instead of requiring a hand-typed device path. No
selection means auto (first available device); one selection pins every
session; multiple selections balance least-loaded. The stored
playback.hw_device value stays the comma-separated list, written in stable
detection order regardless of click order, and a configured-but-undetected
device stays visible so a temporarily missing GPU is not silently dropped
on save.

* fix(playback): make GPU selection and reservation atomic

Review follow-up: resolveSessionHWDevice previously selected the
least-loaded device and incremented its count in two separate critical
sections, so concurrent session starts could all pick the same device
before any reservation landed. Device presence checks now happen outside
the lock and selection + reservation share one critical section; a
concurrency test asserts an exact split across two devices for eight
simultaneous starts, which the two-step version cannot guarantee.

* refactor(playback): one typed GPU acquisition boundary, release on process exit

Replace the CSV-handling spread across resolveSessionHWDevice and
PickRenderDevice with HWDeviceSet + AcquireHWDevice in hwdevice.go: every
GPU workload resolves exactly one device immediately before spawn.
Balancing is explicitly QSV/VAAPI-only — NVENC addresses GPUs by CUDA
index/UUID, so a multi-entry list warns and uses the first entry instead
of collapsing through the path-presence filter. Sessions now release
their reservation only after ffmpeg has been reaped (shutdown waits on
done first), closing the window where a new start could pick a device
the old process still occupied. Render-device sysfs descriptions move to
gpudetect.go so the allocator file owns only selection/reservation.

* fix(downloads): prepared downloads acquire a GPU through the shared pool

PrepareFile resolves the configured hw_device list to one concrete
device via AcquireHWDevice and holds the reservation until ffmpeg exits
(Run is synchronous, so the deferred release is the process-exit
boundary). Download encodes now participate in the same active-load
accounting as streaming sessions instead of best-effort spreading.

* fix(chapterthumbs): resolve hw_device list per extraction via the shared pool

ExtractFrame acquires one concrete device from AcquireHWDevice for the
hardware attempt (released when the attempt finishes) instead of passing
the raw comma-separated value to ffmpeg as a single device path. The
service stops pre-resolving and caching a device at first use — the raw
configured value flows through and each extraction resolves it.

* fix(transcodenode): fresh starts use this node's configured hw_device

/transcode/start constructed TranscodeOpts with an empty HWDevice, so
fresh sessions auto-detected the first GPU and bypassed the configured
list while reconstructed sessions honored it. Both paths now feed the
node-local config value into StartTranscode's shared resolution.

* feat(admin): node-aware GPU inventory on /admin/system/hw-accel

playback.hw_device is one cluster-wide value consumed by every transcode
node, but the endpoint probed only whichever healthy node had the fewest
jobs — an admin could configure devices that don't exist on the other
nodes. The endpoint now probes every healthy node concurrently and
returns a nodes array (URL, name, resolved accel, devices, or probe
error) alongside the backward-compatible flat fields, and the config doc
states the homogeneous-path contract explicitly.

* feat(admin): GPU picker survives empty detection, warns on node divergence

The picker rows are now the union of detected devices and configured
entries, so configured-but-missing devices stay visible (and
deselectable) when detection returns nothing or an older node omits
render_device_details (plain render_devices paths fall back to a generic
label). Per-node inventories from the hw-accel endpoint drive two
warnings: a banner when responding nodes report different device sets,
and a per-row note listing nodes missing that device. The multi-select
is hidden for NVENC — balancing is QSV/VA-API only — with a notice when
a multi-device value is already stored.

* fix(playback): release GPU reservations on process exit

work across the server, bundled web client, Apple clients, and Android clients.

Today there are three partial contracts - the server registry, the web client's
own manifest, and independently owned key constants in each native client - and
they have measurably drifted. The root enabler is that keyUsesUserScope returns
true for any unregistered key, so a client can invent a production setting
unilaterally and the server stores it as an unvalidated string.

The design decides:

Ownership. Every production user-facing setting needs a server-owned manifest
entry, even when the value is stored only on one client. The single exception is
private local.<client>.* diagnostics, bounded by five conditions.

Types and scopes. Native JSON values instead of strings. Five remote scopes plus
client_local, and each definition declares its own resolution order rather than
inheriting a global precedence.

Preferences versus restrictions. internal/policy already resolves
max_playback_quality and metadata-language limits over the same controls this
contract resolves preferences for. Definitions declare constrained_by, the
effective response reports the permitted value alongside the user's stored one,
and a mutation exceeding a restriction is stored rather than rejected - a capped
4K preference should take effect the day the cap lifts, not be destroyed by it.

Compatibility. Widening a scope, adding an enum member, or widening a range is
additive and revision-tagged; narrowing anything needs a new key. introduced_in
is a manifest revision attached to individual enum members and scopes, not just
whole definitions, so a newer client never offers a choice an older server will
reject.

Rollout. One coordinated breaking release, with no compatibility shim,
projection, or client fallback. After the cutover no future setting requires
coordination. No settings version check goes in the authenticated middleware and
nothing returns 426: deleting the old routes already produces the break, and a
gate would be more code in four repos for the same outcome while permanently
coupling every endpoint to one subsystem's versioning.

Scope placement. Appearance and date/time move from account to profile scope.
Account scope was an artifact of pre-profile storage; leaving it there means a
household shares one theme and text size, and any non-child profile can restyle
everyone else.

Read path. Batched context resolution, index requirements, a session-snapshot
rule, and a no-regression benchmark gating storage consolidation - profile_series
resolution is per-item, so a season view would otherwise issue one request per
episode.

Verified against the current server, Apple, and Android implementations. Two
findings shape it: the unknown-key extension bag is real, and v1 scope reads NOT
LOCKED, so removing the legacy surface needs no amendment if it lands before
lock.

* feat(settings): add the canonical settings contract manifest

First implementation step for the cross-platform settings contract (#376).
Adds the artifact everything else depends on: the manifest, its JSON Schema,
the object value schemas, and a Go loader that validates the whole thing at
load time. No routes, no storage, no behavior change — nothing reads this yet.

contracts/settings/v1/ holds the artifact at a stable path because clients
vendor it and generate bindings from it. The embed directive has to sit beside
it (go:embed cannot reach outside its own directory), so that directory is a
tiny Go package containing nothing else; loading and validation live in
internal/settingscontract.

38 definitions: 35 remote, 3 contract-known client_local. That covers every key
the legacy registry accepts, every unregistered key the extension bag was
silently accepting from the web client, every unregistered device key Android
writes, and the profile preference columns that become settings.

Registering the previously-unregistered keys is where the drift shows up, and
the manifest records each case in a notes field:

- ui_theme, ui_text_scale, ui_text_weight, ui_high_contrast,
  ui_custom_theme_vars, and ui_custom_css reached the server only because
  keyUsesUserScope returns true for any unregistered key. They are now typed,
  renamed to the dotted convention every other key uses, and moved to profile
  scope per the design.
- player.match_frame_rate and player.sleep_timer_default_minutes are written by
  Android against a server that does not register them, so every write and reset
  is currently rejected. Registered.
- player.next_up_prompt_seconds is Android's alias for
  playback.next_up_prompt_seconds and does not become a definition; the test
  matrix pins it as a migration alias.
- player.playback_speed is capped at 3.0, matching the server rather than
  Android's 4.0.
- subtitle_appearance becomes playback.subtitle_appearance. Every other
  canonical key carries a domain prefix, and preserving accidental key names is
  an explicit non-goal of the design.

Validation is deliberately stricter than the schema can express. Beyond shape,
it enforces that a resolution order ends in "default", that it only resolves
scopes the definition allows, and — the one most likely to bite — that every
writable scope is actually read, so a setting cannot accept writes at a scope it
will never honor. Defaults are validated against their own value schema, so a
default that violates its own range or enum fails at load. Revision tags are
checked to never run ahead of the manifest revision, which is what makes
revision-aware client filtering trustworthy. Ceiling and floor policy
constraints are rejected on unordered types, where capping would silently do
nothing; playback.preferred_quality's enum is therefore ordered ascending.

ValidateValue is the single validation path, so the mutation endpoint, the
migration, and the manifest's own default checks cannot diverge later. Numbers
decode through json.Number so an integer setting rejects 30.5 rather than
truncating, and object values validate against their referenced JSON Schema
instead of accepting arbitrary JSON the way validateJSONSetting does today.

Canonicalization implements RFC 8785 over the value domain the contract uses:
sorted keys, no insignificant whitespace, ECMAScript number formatting. The
digest is the ETag, and PublicBytes strips maintainer notes so the served
manifest never carries internal commentary.

Promotes santhosh-tekuri/jsonschema/v6 from indirect to direct.

Verification: 124 tests pass across 16 cases; golangci-lint clean;
make verify-local-paths passes. Two failures in internal/api/handlers
(TestRemoveJellyfinCompatWebDisablesWebSetting, the playback v3 seek recovery
test) reproduce unchanged on main and are unrelated.

* feat(settings): give ui.theme a device override

Theme joins text scale, text weight, and high contrast as a profile default
with an optional per-device override, resolving profile_device -> profile ->
default. The right theme is partly a function of the screen and the room — a
light theme on a phone in daylight, a dark one on a TV at night — which is the
same reasoning the other three appearance keys already used.

All four appearance settings now cascade consistently, which also means one
rule to explain in the UI rather than "these three follow the device, that one
does not".

ui.custom_theme_vars and ui.custom_css stay profile-wide. They are authored
styling rather than a contextual preference, so a profile's custom tokens still
apply on top of whichever theme a device resolves to. Recorded in the
definition notes because it is a visible consequence: vars tuned against a dark
theme will sit on top of a light one if a device overrides the theme. Widening
those to profile_device later is an additive revision bump if it turns out to
matter.

Part of #376.

* fix(web): tag local appearance caches with their owning account

The theme, text scale, text weight, high contrast, custom theme variable
and custom CSS caches in localStorage were untagged, so on a shared
browser a second account inherited the first account's appearance: with
no server value of its own, every fallback resolved to whatever the
previous account had stored, and the leftover `silo-theme` key also
suppressed the admin-configured default theme for the new account.

DateTimeFormatProvider already solved this by stamping its cache with the
authenticated user id and refusing another account's values. Extract that
mechanism into `createOwnedCache` in utils/storage.ts (where key
namespacing lives) and put all three groups behind it, so appearance and
custom theme get the same protection instead of a third copy of the rule.

- Each group carries its own owner stamp. A shared stamp would be unsafe:
  the groups are written by hooks nested inside each other, and effects
  run inner-first, so whichever hook stamped first would vouch for the
  other's still-stale values.
- A null owner (auth bootstrapping, or signed out) still trusts the
  cache, which keeps the warm start and the login screen's last look.
- An unstamped cache is not trusted once an account is known, so existing
  users take a one-time appearance reset on first load rather than a
  chance of seeing someone else's settings.
- When a foreign cache is detected the values are dropped and the empty
  cache is handed to the new account, so a later single save cannot
  re-trust the rest of the previous account's state.

Owner is the user id because /settings is user-scoped server side; it
lives in one helper (`appearanceCacheOwner`) so it can be widened if
appearance moves to profile scope. `shouldLoadApiTheme` is gone: it had
become a synonym for `appearanceCacheOwner(...) !== null` with no callers
left.

* fix(settings): make the settings contract enforceable and fix the appearance cache

The contract manifest landed as a document nothing checked. This makes it a
mechanism, and fixes the one defect in the change set that hurt users on merge
rather than at cutover.

Web appearance cache. useTheme cleared the cache for any account whose stamp
did not match and never repopulated it — the only writers were the four
user-action setters — so every upgrading user lost their warm start on every
load, not once, and x-large-text and high-contrast users lost theirs too. The
owner-stamp protocol is replaced with per-account key namespacing
(`silo-theme:7`): a foreign value is absent rather than present-and-distrusted,
so nothing has to be deleted, the first account keeps its warm start, and there
is no shared stamp for a second tab, a stale debounce timer, or an out-of-order
effect to race on. Widening ownership to profile scope, which this manifest
requires, is now a change to appearanceCacheOwner alone. Adds the API-to-cache
mirror useTheme was missing, cancels pending debounced writes across an account
change, and re-seeds provider state during render so no frame paints the
previous account's look.

Canonicalization. writeCanonical used json.Marshal, which HTML-escapes < > and
&, and canonicalNumber used Go's 'g' format — both diverge from RFC 8785, so
the first label containing an ampersand or bound below 1e-4 would have forked
the server's ETag from every conforming client. Output is now byte-identical to
ECMAScript String() across the edge cases, verified against node. The ETag also
covers the value schemas, which decide what the server accepts and previously
could change while the tag stood still. All four derived representations are
memoized; a conditional GET no longer costs a full parse and re-serialize.

Validation. strictUnmarshal's decoder.More() answered false for a stray ] or },
so `true]` validated as a boolean. Enum matching compared fmt.Sprintf tokens, so
the string "3" satisfied an integer member. Declared steps were never enforced.
The language pattern rejected tags both mobile platforms emit unprompted
(en_US, ca-ES-valencia, ar-EG-u-nu-latn) and never normalized case, so en-US and
en-us were two rows for one preference; NormalizeValue now canonicalizes on the
shared path.

Manifest. show_forced_subtitles defaulted false where the server column is NOT
NULL DEFAULT true, which would have turned forced subtitles off for every
profile that never touched it. preferred_quality declared 13 members where the
planner speaks 6 and collapses the rest to auto. metadata_language's allowlist
was bound to the very column it migrates from. subtitle-appearance pinned
fontFamily to three families while Apple stores any installed system font.
Registers five user-facing settings the clients already ship, and corrects three
notes that described Android behaviour that was not true.

Enforcement. The package had no non-test callers, so MustLoad never ran; it now
loads and logs at startup. The inventory test compared the manifest against a
hand-copied map and could not see the drift it named; it now iterates
settingsRegistry and checks defaults too — both verified to fail on injected
drift. Adds .github/workflows/ci.yml, the repo's first CI that runs go test,
go vet, gofmt, and the frontend suite. Known pre-existing failures are named
individually in the Makefile so everything else stays gated and the list can
only shrink.

* fix(settings): align the sleep timer default and range with the shipped client

Android is the only client that implements this setting. It clamps to 0..240
and defaults to 30. The manifest said 0..480 with a default of 0, so a
manifest-driven UI would have offered durations no client can store, and every
user who never opened the picker would have had the preset silently turned off
at cutover.

* ci: give the new workflow the deps it actually needs

The first run exposed two gaps in the workflow itself. go build ./... fails
without libvips headers, because h2non/bimg binds libvips through cgo and
pkg-config; the Dockerfile installs the same package. And pnpm/action-setup
resolves its version from package.json, but there is no package.json at the
repo root — the packageManager field lives in web/package.json, and a job's
defaults.run.working-directory does not apply to an action's inputs.

* test(web): stop the diagnostics download test depending on the Node version

new Response(blob) reads the body through blob.stream(), which jsdom's Blob
does not implement on Node 22 — the version the Dockerfile builds with. The
test passed locally on Node 24 and threw "object.stream is not a function" in
CI. Nothing in it asserts on the body, only that the object URL and filename
reach the anchor, so a string body is equivalent and works on both.

Surfaced by the CI workflow added in this branch, which is the first thing in
this repo to run the frontend suite anywhere but a developer's machine.

* fix(build): copy the settings contract into the container build context

Both Dockerfiles copy cmd/, internal/, migrations/ and web/embed.go, but the
manifest lives in contracts/settings/v1 — an embedded Go package that sits
outside internal/ because clients vendor those files. The image build therefore
fails with "no required module provides package .../contracts/settings/v1".

Caught deploying to the dev box. Nothing had built an image since the manifest
landed: the Docker workflow only runs on pushes to main and workflow_dispatch,
and CI's go build runs against a full checkout, so neither gate covers the
container context. This would have broken the published image on merge.

* fix(settings): enforce the language-tag and step constraints the manifest declares

A sweep of all 43 manifest definitions against the running server (160 checks:
declared default, both boundaries, and deliberate violations for each remote
key) found two places where the live registry accepts what the contract
forbids. Both are fixed by calling the contract's own validators rather than
adding a second implementation.

playback.audio_language was checked as "32 characters or fewer", so the server
stored "!!!" for a field the manifest declares as language_tag — a value track
matching would then silently never match. It now requires a well-formed tag via
settingscontract.NormalizeLanguageTag. The empty string is still accepted: the
string-only endpoint has no way to send null, and both Android and web send ""
to clear the choice, so rejecting it would break clearing the preference.

player.playback_speed declared step 0.05 and nothing enforced it, so 0.26 was
stored — a value no client's stepper can represent and that every client would
silently snap on the next write. settingscontract.StepAligned is now exported
and used by both the contract validator and the registry, so there is one
definition of "on step" rather than two that can drift.

This gives the contract its first production consumer beyond the startup load,
which is the direction Phase 2 continues in.

Also fixes a genuinely flaky test that the new CI gate would have hit
intermittently: TestRemoveJellyfinCompatWebDisablesWebSetting used t.TempDir as
the install root, but the endpoint returns 202 and its goroutine keeps writing
there after the test body returns, so cleanup tripped "directory not empty"
roughly one run in four. Confirmed pre-existing and unrelated to settings; the
suite now passes six consecutive full-package runs.

* fix(settings): keep widened numeric bounds resolvable at older revisions

A bound was one scalar plus the revision that introduced it, which discards
the value it replaced. Widening a maximum from 240 to 480 at revision 3 left
a revision-3 client with no correct answer against a revision-1 server:
honoring 480 offers values that server rejects, and filtering the tagged
bound out leaves the setting unbounded. Since clients are specified to filter
their pinned contract against the server's advertised revision, the bound has
to carry what it used to be.

Bounds now hold their full history, oldest first, and AtRevision hands back
the limit a given peer actually enforces. A bound nobody has widened still
serializes as a bare number, so the manifest reads the same and untouched
entries do not churn the ETag.

Validation gains the rules the representation makes checkable: a maximum may
only grow and a minimum may only shrink, history is strictly ordered, later
entries must say when they arrived, and the first entry cannot predate the
definition. That last rule is the lower bound allowed_scopes already
enforced; the same gap is closed for enum members, which could previously
claim to predate the definition containing them.

Reported by Codex review on #479.

* fix(settings): accept the partial subtitle appearance objects already stored

The schema required all nine properties, but the current API accepts and
round-trips sparse objects — settings_device_test.go stores
{"fontSize":"xxlarge"} and reads it back — and the web client has always
merged whatever it gets over DEFAULT_SUBTITLE_APPEARANCE. Requiring the full
object would have made the cutover migration quarantine preferences users
really set, or block on them.

Every property is now optional and a stored value is documented as a sparse
override merged over the definition's complete default. An empty object is
still rejected: an override that overrides nothing is the same state as no
override, which the contract represents as unset.

Cross-scope resolution is deliberately unchanged. A device override still
replaces the profile's object rather than merging into it, because a device
override means "draw subtitles this way on this screen", not "amend the
profile" — and that is what the server does today.

Reported by Codex review on #479.

* fix(jellycompat): scan the parent directory when a sidecar changes

Autoscan matched scantrigger rejections by comparing RequestError.Message
against literal strings. One of those messages became "Unsupported media file
extension for library type" and the copy in handlers_autoscan.go did not, so
the comparison silently stopped matching.

The effect is user-visible: a Jellyfin client posting a change for Movie.nfo
or poster.jpg gets a 400 and the batch is abandoned, when the sidecar should
have resolved to a scan of the directory containing it. Three tests covered
exactly this and had been excluded rather than read.

RequestError now carries a Reason the caller can switch on. Message stays
prose for the client reading the response — it is meant to be reworded, and
nothing should break when it is.

Also makes two tests honest about asynchronous work. The Jellyfin Web
teardown deleted its install root while the operation goroutine was still
writing to it, where a late write recreates a path RemoveAll already walked
past; it now waits for the operation's terminal state, which required
exporting CurrentWebOperation. And the direct-play If-Range test pinned size
and mtime so ctime was the only remaining validator, then read it back inside
a single coarse-clock tick — it failed about 85% of the time on main for a
reason unrelated to what it tests, and now rewrites until the stamp moves.

With those fixed, GOTEST_KNOWN_FAILURES is empty and gone: make test-go runs
the whole Go suite. The one test that cannot pass yet —
TestHandleReplanPlaybackV3SeekFailureRecoveryNeverChangesMediaVersion, which
has failed since the commit that introduced it and describes unimplemented v3
planner behavior — carries a t.Skip explaining that where the test is, rather
than a regex in the Makefile.

Reported by CodeRabbit review on #479.

* fix(settings): reject JSON the decoder would otherwise rewrite

Two cases where encoding/json accepts input by quietly changing it, which is
the one thing a contract promising byte-identical agreement between peers
cannot tolerate.

Duplicate object properties. jsonschema.UnmarshalJSON keeps the last
occurrence, so {"fontSize":"small","fontSize":"large"} validated and stored
"large". Which one wins is a property of the parser, not of the contract: a
client generated against a different JSON library can disagree about what it
just sent, and the canonical form cannot represent the duplicate at all.

Lone surrogates. An unpaired \ud800 became U+FFFD and canonicalization
reported success, so the server would issue canonical bytes and an ETag for
an artifact a conforming implementation must refuse — RFC 8785 requires
terminating here. Substitution also means the value read back is not the
value written.

Both checks run before the decode that would hide them, on the shared
decodeJSON path that the manifest, its public projection and every value
schema go through, and again on the object branch of ValidateValue, which
uses a different decoder.

Reported by Codex review on #479.

* ci: gate Go lint on the lines a branch changes

AGENTS.md told contributors CI ran the same checks as `make lint`, and the Go
job ran only gofmt and vet. A change failing the documented Go lint gate
passed all three jobs.

Running the linter as-is is not an option: the tree has ~296 findings today,
which is why this half of `make lint` was never enforced. Blocking every PR
on a cleanup nobody has scheduled gets the gate deleted again, so CI runs
with --new-from-merge-base and only the lines a branch touches have to be
clean. The count can then only fall.

golangci-lint is built from source at a pinned version rather than
downloaded. A released binary refuses to run against a Go newer than the one
it was built with, and go.mod here tracks Go closely enough that the current
release already fails that way on 1.26.4.

.golangci.yml declared version 2 while still using v1's issues.exclude-rules
key. Current golangci-lint ignores it, so the "allow repeated strings and
unchecked cleanup errors in tests" exclusions silently did not apply — 16
findings in test files that the config says to skip. Moved to
linters.exclusions, which `golangci-lint config verify` accepts.

The four lines this surfaced in scantrigger are fixed rather than excluded:
its repeated status codes and messages are now named constants, so one
condition cannot end up worded two ways.

Also drops the workflow token to contents:read and stops persisting
credentials in the three checkouts, neither of which any job needs.

Reported by CodeRabbit and Codex review on #479.

* docs(v1): record the settings removal as a pre-lock exception

The design removes the legacy /api/v1/settings routes and the profile DTO
preference fields, while AGENTS.md states /api/v1 is additive-only and
removals go through Deprecation/Sunset. Read together those contradict.

They do not actually conflict: v1-scope.md scopes the additive-only rule to
"when the scope locks", and the scope is still open, so a removal taken now
is in scope and there is no amendment process to invoke yet. But that
reasoning lived only in the settings design, where nobody checking the API
policy would find it.

v1-scope.md now carries a pre-lock removals table naming what goes and why
waiting is worse, and states the deadline the argument depends on: a removal
listed there must ship before lock or fall back to Deprecation/Sunset.
AGENTS.md points at the table and says to treat an unlisted removal as a
mistake.

Reported by CodeRabbit review on #479.

* fix(settings): clear the remaining review findings

Small, unrelated except that each was raised on #479.

compileObjectSchemas parsed every non-directory file under schemas/ as a JSON
Schema, so a stray editor backup or .DS_Store would panic the server at
startup through MustLoad. schema_ref can only name a .json file; anything
else is skipped.

cmd/silo used MustLoad while the ETag check beside it and every other startup
failure use log.Fatalf. It now fails the same way, so a bad contract prints
an error instead of a stack trace.

TestRegistryDefaultsMatchTheContract called scalarDefault before handling
null, and scalarDefault rejects null as non-scalar — so the subtest skipped
and the comparison after it was unreachable. A nullable contract default
could disagree with a non-empty registry default and nothing failed.
Confirmed by injecting that drift, which now reports it.

The three appearance providers each adapted the auth context to
AppearanceAuth with identical code, putting the shape of auth back in three
places that widening cache ownership would have to find. useAppearanceCacheOwner
now does it once.

useTheme.test.ts cleared storage.KEYS between cases, but appearanceCache
writes namespaced keys and an owner pointer that are not in that list, so
both survived and the suite was order-dependent. It clears the store, as
storage.test.ts already did.

The abs_smart_collection_store comment is reworded rather than given back its
SQL quotes: gofmt folds a pair of apostrophes in a doc comment into a
typographic quote, which is how it became one in the first place.

Reported by CodeRabbit review on #479.

* feat(settings): add canonical typed storage for the settings contract

The cross-platform settings contract needs one typed store behind it before a
resolver, routes or a migration can exist. This adds that storage to both
user-store backends and holds them to identical behavior.

PostgreSQL gets user_setting_values with the scope CHECK constraints, the five
partial unique indexes that enforce one explicit value per identity, and the
covering indexes the one-query read path needs, plus user_setting_mutations for
mutation_id idempotency and the inert user_setting_migration_rejects audit
table. The per-user SQLite store gets the same shape minus user_id, since that
database is already user-scoped.

The UserStore interface grows the typed operations: read one explicit value at
one scope, collect every candidate row for a resolution request in a single
query, upsert with a revision increment, unset, and the idempotency receipt
operations. The resolution read deliberately returns unranked candidates so the
resolver can rank in Go — one query per request, never one per scope, which the
pgx query-count test pins.

Delete behavior is application-enforced. Neither backend can inherit it from
constraints: the SQLite store declares no foreign keys, and library, series and
device columns are not FK targets in Postgres either. Profile deletion cascades
to profile-anchored values while account scope survives, forgetting a device
clears its profile_device values alongside the legacy overrides, and the
library/series purges remove only what is scoped to that entity.

The shared conformance suite covers all of it, including the set-versus-unset
distinction for false, 0, "" and null, so a divergence between the two backends
fails a test rather than reaching a client.

Part of #376

* test(settings): pin the settings-value schema constraints in both backends

Completes the storage track. The conformance suite exercises the store API,
which validates identities in Go before any SQL runs — so nothing noticed
whether the CHECK constraints and partial unique indexes actually existed.
The one-time migration writes these rows in bulk without going through the
per-request path, so the schema is the only thing guarding it.

Adds constraint tests to both backends covering every scope's column
requirements, rejection of an unknown scope, a profile that does not exist,
non-JSON values, and each of the five partial unique indexes.

Also clears the lint the storage commit did not get to: sql.ErrNoRows and
pgx.ErrNoRows compared with == rather than errors.Is (which fails on a
wrapped error), an unchecked rows.Close, and repeated fixture literals in the
shared suite now named so a backend that confuses two scope columns fails on
the assertion rather than on a typo.

* fix(settings): close the review findings in the validator and the theme cache

Four defects the existing tests did not reach.

The web theme resolver compared the server's value against the appearance
cache and fell back when they agreed, but the mirroring effect writes the
server's value into that same cache — so the comparison held on the first
render and stopped holding on the second, reverting an explicitly chosen
theme to the default. The server's value is this account's own stored
choice, so it now simply wins. The regression test re-renders rather than
asserting on the first paint, which is why the original one passed.

golangci-lint's exclusions.paths is a path regex, not a directory list, so
a bare `web` also excluded internal/jellycompat/web_component.go,
internal/webhooksync/, internal/notifications/webhook*.go and eleven other
non-test files that were being linted before. Anchored.

json.Number is a string kind, so `"1.5"` unmarshalled into it happily and
Float64 parsed the quoted digits: a numeric setting validated as a JSON
string and NormalizeValue stored the quoted form into jsonb. Rejected.

The lone-surrogate check ran only on the object branch, so a lone surrogate
in ui.custom_css decoded to U+FFFD on SQLite and was refused outright by
Postgres jsonb — the two backends disagreeing about whether the same value
could be stored. Hoisted to cover every type.

The strict language-tag validation this branch added is correct, but it
rejects what the shipped Android client sends; the companion fix is
silo-android 4aeb78b4.

* test(auth): stop TestJWT_TamperedToken passing a valid signature

The test overwrote the last character of the signature with "X". An
HMAC-SHA256 signature is 32 bytes, so its base64url encoding is 43
characters and the final one carries only four significant bits — U, V, W
and X all decode to the same trailing byte. Roughly one token in sixteen
was therefore left byte-identical and validly signed, and the test failed
because ValidateToken correctly accepted it.

Measured at 3098/50000 (6.2%) over distinct signatures; it just failed the
Go job on this branch for reasons unrelated to the branch. Flipping a
character in the middle of the signature is 0/50000.

* fix(settings): reject raw invalid UTF-8, not just escaped surrogates

The previous commit hoisted the lone-surrogate check to cover every value
type, but that only closes the escaped path. A raw 0xff byte inside a
quoted string — what an HTTP body carries when a client encodes text in the
wrong charset — is not an escape, so the surrogate scan never sees it, while
encoding/json still substitutes U+FFFD and reports success. NormalizeValue
then stores the original bytes, which SQLite's json_valid accepts and
Postgres jsonb refuses: the same backend divergence, reached the other way.

* fix(settings): size the library page state bound to what the web client writes

ui.library_page_state's `search` was bounded at 256 characters. The web
client serializes an advanced library view as URLSearchParams, encoding each
filter rule as three groups[i][rules][j][field|op|value] keys — measured at
216 characters for one rule, 518 for three, 820 for five.

The current endpoint validates this key by checking only that it parses, so
those oversized values are already stored in production. Typing them at the
declared bound would have failed the migration for anyone who had saved a
view with more than one filter rule, and rejected the equivalent write
afterwards.

Raised to 4096, which clears ten rules with room to spare while staying a
real bound. The test pins it against the key shapes
libraryPageSearchParams.ts actually emits rather than a round number.

Reported by the Codex review bot; the lengths above were measured by calling
serializeLibraryPageSearchParams, not estimated.

* feat(settings): split quality into two axes and register the orphan keys

Two manifest changes the cutover needs.

**Quality becomes resolution + bitrate.** The legacy ladder values
(1080p-high, 720p-medium, 1080p-8, 420p, 328p) were never a third dimension
— they are a bitrate spelled into the resolution string. The web player
already decomposes them: useTranscodeQuality.ts defines 1080p-high as
{resolution: 1080p, bitrate: 10000} and sends the two separately, so the
compound form never reached the wire. Downloads went further and kept only
a bitrate ladder.

So playback.preferred_quality keeps the six clean resolutions and
playback.max_bitrate_kbps becomes the second axis, nullable because
"uncapped" is a real answer and a numeric sentinel would need widening
every time hardware improves. Clients compose their own presets from the
pair, which means retuning what "High" means is a client release rather
than a contract break. Migration decomposes each legacy value losslessly,
so none of them lands in the rejects table.

**The five extension-bag keys are now definitions.** card_overlays,
next_up_mode, sidebar_pins, disabled_library_ids and library_order reached
the server only through the unknown-key path, stored as unvalidated
strings. Two of them the server reads back — next_up_mode decides home
section assembly and card_overlays falls back to an admin default — so
they cannot be demoted to client-local. Registering them is what lets the
extension bag close.

Adds three schemas for their shapes and a test that exercises every
schema_ref against a real value: each of these is nullable with a null
default, so the existing default-validation test returns at the null branch
without ever compiling the reference.

* feat(settings): add the canonical resolution engine

One answer to "what is this setting, for this profile, on this device, for
this content". Before this, each caller carried its own ladder:
catalog/detail.go resolved subtitles across four levels by hand and audio
across three, handlers/settings.go had a two-level device/user resolution
with a lazy write-back inside a GET, and jellycompat read profile columns
directly. Those disagreed about precedence, which is the drift the contract
exists to remove.

Resolution is one batched read regardless of how many keys, libraries, or
series are in play — ranking happens in Go against each definition's
declared resolution_order. Five sequential index lookups per key per item
is the implementation the design rejects, and a season view is exactly
where it would have shown up.

An absent identity drops its scope rather than erroring, so one code path
serves an identified client, an anonymous jellycompat seed, and a batch
spanning many series. Rows for a foreign profile, device, library or series
are ignored even though the batched read returns them.

Constraints narrow without destroying: a capped 4K preference resolves to
the cap, reports itself constrained, and keeps the authored value so it
takes effect the day the cap lifts. Two cases needed care — null on a
nullable numeric means unbounded, so a ceiling must cap it rather than rank
it equal and let the value that most needs capping slip past; and an
allowlist falls back to a permitted member rather than the definition's
default, which may itself be outside the list.

Adds ValueSchema.CompareValues to the contract package, since ordering
values is what makes a ceiling or floor mean anything and value semantics
belong with the schema that declares them.

* feat(settings): add the one-time migration planner

The conversion rules from legacy settings storage to canonical values, as
ordinary Go rather than twice in two SQL dialects. Both backends read their
own rows, hand them to Plan, and write what comes back — so the decisions
are testable without a database and SQLite and Postgres cannot drift apart
in what they decide.

The rules that needed care, each pinned by a test:

Column defaults are not choices. quality_preference is NOT NULL DEFAULT
'1080p' while the contract defaults to auto, so migrating the column
unconditionally would pin every profile in the install to 1080p having
never chosen it — and that stored value would then outrank the contract
default forever. Same for language 'en', subtitle_mode 'auto', and
show_forced_subtitles true.

The empty string is unset, not a value. The legacy string API had no way to
send null, so both Android and web spell "clear my choice" as "". Storing
that would make a cleared setting outrank the default.

Legacy quality decomposes rather than rejects. Every compound value maps to
a resolution and a bitrate from the ladder in useTranscodeQuality.ts, so
nothing lands in the rejects table.

Account rows fan out to every profile, which is the account-to-profile move
the contract makes for appearance and search scope: a household that shared
one theme each end up owning theirs.

Legacy strings become typed JSON — "true" to true, "30" to 30 — or every
generated binding would fail to decode what the migration wrote.

Nullability differs per backend, so profile columns arrive as pointers and
the caller resolves "chose the default" versus "never written" when it
reads. jellycompat's DisplayPreferences blobs ride the same table under
synthetic keys and are left alone; they are that subsystem's storage.

Everything that cannot convert is recorded with a reason rather than
dropped, and a final test asserts every planned row would be accepted by
the mutation endpoint's own validation.

* feat(settings): run the one-time migration on the SQLite backend

Wires the planner to real storage as userdb migration V15. V14 created the
tables; this fills them.

It runs inside runMigrations' existing transaction, so a database either
comes out fully migrated or untouched — a partial migration is the one
state neither the operator's backup nor a rollback covers. Pinned by a test
that rolls back and asserts nothing was left behind.

Two things the wiring had to get right that the planner could not see:

Reject identities are JSON. Postgres declares that column jsonb NOT NULL
and SQLite guards it with a json_valid CHECK, so the free-form
"profile=p1 device=d1" the planner emitted would have failed to insert — on
exactly the rows the table exists to record. They are structured documents
now, which is also queryable.

Subtitle and audio preferences are two tables keyed the same way, so they
merge into one per-series record before planning. Converting them
independently would have produced two rows racing for the same identity.

Every legacy read tolerates a missing table, since this runs against
databases created at any schema version, and preferred_metadata_language is
deliberately absent: that column exists only in the Postgres schema.

Tested end to end against a real database rather than only through the
planner — the rows land, satisfy the scope CHECK and the partial unique
indexes, and hold valid JSON. Also covers the empty-install case and
asserts a second run fails rather than silently doubling every value.

* feat(settings): run the one-time migration on the Postgres backend

The mirror of userdb V15, registered with goose as a Go migration rather
than SQL: the conversion validates every value against its own definition
and re-encodes it as typed JSON, and one legacy quality string becomes two
rows — neither is expressible in SQL without duplicating the manifest. The
rules stay in internal/settingsmigrate, so the two backends cannot disagree.

RunTx, so the whole backfill lands in goose's transaction. The down
migration empties the canonical tables; the legacy ones are never touched
by the up, which is what keeps the cutover reversible until the follow-up
migration drops the superseded columns.

preferred_metadata_language is read here and only here — the column exists
in this schema and not in SQLite's, so this is the sole source for
catalog.metadata_language.

Verified against a real Postgres: the full goose chain runs, 1080p-high
decomposes to ("1080p", 10000), values land as typed jsonb rather than
strings (jsonb_typeof reports number), rejects carry a queryable jsonb
identity, and the composite profile foreign key refuses a row naming a
profile that does not exist.

* feat(settings): add the canonical settings API

The routes that make the typed storage reachable. Until now the manifest,
the resolver and the migration all existed with nothing able to call them.

GET /settings/contract serves the public manifest behind an ETag — clients
vendor a pinned copy and generate bindings from it, so the common request
asks "still the same contract?" rather than transferring it. Its
capabilities sibling reports revision and supported scopes for feature
detection instead of version sniffing.

/settings/values/{key} reads, writes and clears an explicit value at one
named scope, which is what a reset affordance needs: "did I set this here"
is a different question from "what applies", and the old endpoint could
only answer a blurred version of both. Scope comes from the query while
profile and device come from session headers, so one profile cannot address
another's settings by naming it.

/settings/values/effective resolves any number of keys in one request, with
the resolution ladder and the source of each answer reported so a client can
offer "reset this device's override" against the exact row holding it.
Asking for no keys returns every remote setting, which is what a settings
screen wants.

Writes are idempotent when a client sends X-Silo-Mutation-Id: a retry after
a dropped response replays the receipt, and reusing an id with different
content is a conflict rather than a silent overwrite of the wrong thing.

Three things the string-only endpoint could not do, each pinned by a test:
an unknown key is refused rather than stored in the extension bag, values
are checked against their declared type and range, and a write to a scope
the definition does not allow is rejected.

Registered before the catch-all /{key} routes, which would otherwise
swallow "contract" and "values" as setting names. The legacy endpoints stay
live for now; deleting them is the next commit, once their consumers move.

* feat(settings): generate typed bindings for all four languages

One generator rather than one per repo. The point of the contract is that
four codebases agree on keys, types, scopes and defaults, and four
independently written generators would be four chances to disagree.

Go and TypeScript land in this repo; Kotlin and Swift are written into the
sibling client checkouts, skipped with a note when they are not present so
a server-only developer can still run it. Output is sorted by key so an
unrelated manifest edit does not produce spurious diffs.

The Kotlin output is the interesting one: it generates the DeviceSettings
allowlist Android maintained by hand, plus the BOOLEAN_KEYS/INT_KEYS/
DOUBLE_KEYS classification it kept as a *second* hand-maintained table that
had to agree with the first. Both are manifest questions now, so the whole
class of "wrote a local key to the server" and "flushed a value the store
could not parse" bugs stops being possible by construction.

The TypeScript output carries the full definition table — labels, controls,
enum members, bounds — so web/src/lib/settingsManifest.ts can be deleted
rather than kept in sync: it declared 17 definitions against the contract's
49, with its own two-scope model that does not match the contract's five.

make verify-settings-bindings fails when the committed output disagrees
with the manifest, wired into CI, so a manifest change cannot merge leaving
every client reading stale keys.

* feat(web): add the two-axis quality picker and typed settings hooks

Quality becomes one picker over two stored values.

The server holds a resolution cap and a bandwidth cap independently, which
is what the player has always sent on the wire — useTranscodeQuality.ts has
decomposed 1080p-high into {resolution, bitrate} for as long as it has
existed. Presets live in the client rather than the contract so retuning
what "High" means is a one-line edit here instead of a contract change four
codebases have to agree on, and an older server keeps working because it
only ever sees the two axes it already understands.

A combination no preset covers still gets a truthful label rather than a
picker showing the wrong entry: reachable by setting the axes separately
through the API, or from a legacy value whose bitrate is off this ladder.
Choosing an uncapped preset clears the bitrate rather than storing a
sentinel, so "no cap" stays the absence of a value at every layer.

Adds hooks over the canonical API alongside the legacy ones rather than
replacing them wholesale — a key that is not in the manifest cannot be
expressed, because SettingKey is generated from it, and the default for an
unset value comes from the generated table rather than a literal at the
call site. That last part is what stops the flip-off bug the Apple client
carries a hand-written guard for.

A test asserts every preset composes values the contract actually accepts,
so a preset naming a resolution outside the enum or a bitrate outside the
declared bounds fails here rather than 400ing when a user picks it.

* feat(settings): resolve catalog playback preferences through the contract

catalog/detail.go held the two hardest ladders in the codebase: subtitles
resolved across four levels by hand, audio across three, each partially
overriding the last through Has* flags. Both now call the canonical
resolver, so the precedence lives in the manifest and this file cannot
disagree with the contract about which override wins. Adding a scope is a
manifest change rather than another branch here.

The subtitle track signature stays on its specialized table — it identifies
a concrete track rather than expressing a preference, so it is not a
setting.

Resolution keeps the memoization the old lookups had: the audio resolver
still reads once per profile and once per library rather than once per
file, which is what kept a many-track audiobook detail page fast. The test
that guards it now counts resolver reads instead of GetProfile calls, since
the guarantee is about scaling with file count rather than about which
method does the reading.

Four tests seeded the profile column directly. That column is a migration
source now, not a read path, so they seed the canonical value instead —
they were passing against storage nothing reads.

* feat(settings): close the unknown-key extension bag

keyUsesUserScope returned true for any key the registry did not know, so a
client could invent a production setting unilaterally and the server stored
it as an unvalidated string. That is how six ui.* settings and five orphan
keys reached production untyped, and it is the root enabler the design
names.

An unknown key is no longer a user setting, so the legacy write path
rejects it and the canonical API — which validates every value against its
own definition — is the only way to store something new.

jellycompat's DisplayPreferences blobs ride the same table under synthetic
keys and keep working: they are that subsystem's storage rather than user
settings, and they move to dedicated storage in the follow-up rather than
being dropped here.

Also repoints the DisplayPreferences seed at the canonical resolver.
Resolved at profile scope with no device on purpose — Jellyfin clients do
not carry Silo's device identity, so a device override leaking into the
seed would hand one device's settings to every Jellyfin client on the
account.

* feat(settings): enforce viewer quality caps through resolver constraints

constraintsFor was the unwired half of the preferences-versus-restrictions
seam: it returned nil, so a profile capped at 1080p by policy still resolved
its stored 2160p preference at face value through the effective endpoint.

The settings routes are mounted inside RequireViewerAccess, so the resolved
access scope is already on the request context. Scope.MaxPlaybackQuality
holds a literal member of the contract's quality enum ("1080p"/"2160p"),
which is exactly what the manifest binds playback.preferred_quality's
ceiling to under policy_input "max_playback_quality" — so the wiring is a
direct map with no translation table. An empty value means the policy sets
no cap, expressed by returning nil so the resolver leaves the preference
alone.

catalog.metadata_language deliberately stays unconstrained: the manifest
notes record that the allowlist draft was circular (the policy input it
would bind to is populated from the very preference it would narrow).

The handler test covers both halves of the seam: a 2160p preference under a
1080p cap resolves to the cap with constrained:true/ceiling and the authored
value reported in stored_value, the stored row itself is not rewritten, and
an uncapped viewer gets the preference unchanged with no constraint noise.

* feat(settings): publish user_settings change events

Add a user_settings realtime channel so clients learn when a setting
changed on another device without polling. The channel is modeled on
user_state: non-admin subscribable, per-user addressed envelopes, null
snapshot.

SettingValuesHandler gains an EventsHub and publishes
user_settings.changed after every successful PUT and DELETE on
/settings/values/{key}. The payload carries only key, scope and
profile_id — never the value. Admins receive every user's user-scoped
events, so a value in the payload would leak private settings to
admins; interested clients re-fetch over the scoped REST API instead.
The payload is always non-empty because an empty Data falls back to a
null snapshot in the hub. A nil hub (tests) skips publishing.

* feat(settings): sweep expired mutation receipts daily

Setting-mutation idempotency receipts were written with an expires_at that
nothing enforced, so the table grew forever. Add a hidden daily system task
(05:00) that walks every login account, opens its user store, and calls
DeleteExpiredSettingMutations. A user whose store fails to open or sweep is
logged and skipped so one broken store cannot stall retention for everyone
else; the delete is idempotent, so the next run repairs anything missed.

* refactor(settings): resolve metadata language canonically in access and policy

Repoint the last legacy column readers onto canonical contract resolution
(settings cutover task A4a):

- access.Resolver and policy.ViewerResolver now resolve
  catalog.metadata_language through settingsresolve (profile scope ->
  contract default) via a shared access.PreferredMetadataLanguage helper,
  instead of reading user_profiles.preferred_metadata_language. Resolution
  is deliberately unconstrained: the policy input this preference feeds is
  the one a constraint would have to reference, which is circular — see the
  key's manifest notes.
- playback start now resolves playback.audio_language canonically for the
  profile default instead of reading user_profiles.language, matching the
  catalog detail path. Series and library override handling is unchanged.
- items.go needed no change: it already consumes the resolver-produced
  scope.PreferredMetadataLanguage.

The legacy columns keep their values but are no longer read on these
paths; a profile with only a column value now resolves to the contract
default, and a stored canonical value wins. Tests pin both directions in
access, policy (including scope parity, where the column is now a decoy),
and the playback handler. Read cost is one batched store read per
resolution, same as the profile-row read it replaces.

* refactor(jellycompat): give DisplayPreferences its own table

The Jellyfin DisplayPreferences blobs rode the legacy user_settings
key/value table under synthetic jellycompat:* keys, which forced the
legacy settings API to carry a prefix carve-out in its otherwise-closed
unknown-key gate. They are the compat subsystem's storage, not user
settings: the contract neither validates nor resolves them.

Move them to a dedicated jellycompat_displayprefs table in both
backends, keyed by (prefs id, client) per user, with the blob stored as
opaque text served back byte-for-byte (deliberately not jsonb, which
would re-serialize it). The data-copy migrations — per-user SQLite V16
and a paired SQL + Go goose migration for Postgres — are transactional
and harmless to re-run, and both drive their key parsing and row
classification from the new internal/jellycompat/displayprefs package
so the backends cannot diverge, following the internal/settingsmigrate
precedent. A jellycompat:* row that does not parse as a DisplayPrefs
key (only ever writable through the removed carve-out) is recorded in
user_setting_migration_rejects rather than silently deleted.

With the last non-settings tenant gone, the jellycompatSettingPrefix
carve-out is deleted: the legacy settings endpoints now refuse
jellycompat:* keys like any other unknown key and never surface them.

* feat(settings): serve admin user-settings through the canonical API

Replace the ten string-registry /admin/users/{id}/settings* and
device-settings* routes with the canonical contract surface: one list of
every explicit value the target user has stored across all scopes, and
set/delete at an explicit scope named in the query string.

The admin handlers live on SettingValuesHandler and share the session
routes' implementation rather than duplicating it — the same key/scope
parsing, identity validation, contract scope allowance, value
normalization and mutation-receipt idempotency, factored into
keyedScopeFromRequest/completeIdentity and setValueAt/deleteValueAt.
The only admin-specific parts are the target user coming from the path,
profile and device ids coming from the query (an admin holds no session
claim to the user being inspected, so its named profile is checked to
exist), and change events attributed to the target user so their
clients refresh.

The list is a new UserStore read, ListAllSettingValues, implemented in
both backends and pinned by the shared storetest conformance suite:
the admin surface wants the stored truth (which overrides exist, for a
per-row reset affordance), which no resolution-shaped read answers.

The ten removed routes are recorded in the pre-lock removals table in
docs/architecture/v1-scope.md per the v1 API rules; the web admin
device-overrides page moves onto the new surface in the Phase B
rewrite inside this same unmerged PR.

* test(settings): add the cross-platform conformance fixture and its Go and web runners

contracts/settings/v1/conformance.json is the spec's named drift gate: 21
hand-authored cases of {keys, stored rows, context, constraints, expected
effective value + source}, every one executable against the shipped manifest.
They pin the semantics most likely to drift across four resolver
implementations: the full resolution ladder (series > library > device >
profile > default), an absent identity dropping its scopes, foreign-identity
rows never resolving, ceiling caps that report the authored value with
constrained:true, the ordered-enum sentinels (auto below every cap, original
above), null-on-a-nullable-numeric meaning unbounded and being brought down by
a ceiling but ignored by a floor, allowlist falling back to the first allowed
member rather than the (possibly forbidden) default, and
playback.subtitle_appearance resolving device > profile only with the sparse
device object replacing, not merging. Cases may inject a constraint binding
onto a copy of a real definition so constraint kinds no shipped definition
carries stay testable.

The Go runner (internal/settingsresolve/conformance_test.go) resolves each
case through the real resolver against the embedded manifest. The web runner
(web/src/lib/settingsConformance.test.ts) runs the same cases through a new
client-side resolver, web/src/lib/settingsResolve.ts, which mirrors the
server's semantics; the TypeScript bindings now carry each definition's
ordered flag and constrained_by binding so that resolver derives constraint
behavior from the contract instead of hardcoding it. Both runners reject
unknown fixture fields — schema drift in the fixture itself is drift — and
both refuse a fixture authored against a different manifest revision.

The fixture travels with the bindings: make settings-bindings vendors the copy
the web runner reads, and make verify-settings-bindings fails CI when that
copy goes stale. The Kotlin and Swift copies land together with their runners
in the client repos, which will pick their own test-resource paths.

* fix(settings): review pass over the phase A stack

Fixes the eight adversarially-confirmed defects the review of the
unpushed phase A stack (40e0f77a..1f2c7fe4) found, each with a test
that fails without its fix.

Writers left behind by the language cutover (high). 22e9d7f1 made
access, policy and playback start resolve catalog.metadata_language and
playback.audio_language exclusively from user_setting_values, but
POST/PUT /profiles — the write path the shipped web UI uses — still
wrote only the legacy columns, so a language change after the one-time
backfill never took effect (a stale backfilled row, or the contract
default, won forever). Profile mutations now mirror their preference
fields into the canonical profile-scope rows through the same contract
validation /settings/values applies (audio, subtitle and metadata
language, subtitle mode, forced subtitles; the empty string clears the
row, matching the migration's unset spelling), publish
user_settings.changed for each row moved, and 400 on a value the
canonical endpoint would refuse. quality_preference is deliberately not
mirrored: the server never resolves the legacy column and the two-axis
picker already writes canonically.

Web admin settings 404s (high + medium). facad78d removed the ten
/admin/users/{id}/settings* and device-settings* routes but shipped no
web changes, so the user-detail settings and device-overrides tabs and
the devices-page override editor were dead. The seven admin hooks now
speak the canonical values API: one list across all scopes feeds both
tabs, mutations address an explicit scope identity, values re-type
through the generated contract (display stringifies for the
registry-era controls), device rows are enriched with device and
profile names client-side, and the removed bulk device reset becomes
per-key deletes that treat 404 as already-reset.

Silent metadata-language degrade (medium). PreferredMetadataLanguage
now logs a warning with the profile and error when contract load or
store resolution fails, so pool exhaustion is distinguishable from "no
preference"; the healthy paths stay quiet.

Displayprefs move data loss (medium). Under READ COMMITTED the blanket
pattern DELETEs in moveDisplayPrefs/unmoveDisplayPrefs could destroy a
row an old-binary instance committed between the SELECT and the DELETE
during a rolling deploy — reproduced against real Postgres. Both
directions now delete only the exact rows they read (rejects restore by
primary key), leaving a late row stranded for a re-run to pick up.

Coverage the review proved missing (medium x3): admin mutations are now
tested to attribute change events to the target user, not the acting
admin (the exact regression passed the whole suite before); the
user_settings websocket channel is subscribed through the real events
websocket, failing if the channel is dropped from either
allowedChannelsForRole or AllChannels; and the conformance fixture
gains three locked-constraint cases (replace, equal-value pass-through,
locked default) so the Go and TypeScript locked branches — previously
executable by no test on either platform — are pinned by the shared
drift gate.

* feat(web): read and write appearance and format preferences through the settings contract

Move the four identity-sensitive preference hooks — useTheme,
useCustomTheme, useDateTimeFormat, useSearchMediaScope — off the legacy
string-only /settings endpoints and onto the canonical settings API.
Each surface now reads through one batched useEffectiveSettings call and
writes via useSetSettingValue at scope "profile", matching what the
generated manifest declares: ui.theme / ui.text_scale / ui.text_weight /
ui.high_contrast are profile-scoped with a profile_device override the
effective read already resolves (no device-override UI exists, so writes
stay profile-wide), and ui.custom_theme_vars / ui.custom_css /
ui.date_format / ui.time_format / search.media_scope are profile-wide.
Keys come from the generated SETTING_KEYS table, so a typo'd or
unmanifested key can no longer be expressed.

Because the canonical effective endpoint always answers — resolving
unset keys to the contract default with source "default" — the hooks now
use the source to distinguish "the profile chose this" from "nobody
stored anything". That preserves the admin-default theme layering and
keeps resolved-but-unchosen values out of the warm-start mirror.

ui.theme moving account→profile scope means the appearance warm-start
cache must not be shared by sibling profiles on one account, so
appearanceCacheOwner widens its token from the user id to user id plus
active profile id. Every cache read/write already resolves through that
one function, so no call site could be left behind; the API→cache
mirror, the render-time re-seed on identity change, and the debounced
write cancellation all follow automatically. The ownership tests now
cover profile switches within one account: no theme/text-scale/CSS leaks
between profiles, each profile's warm start survives the switch, and a
debounce armed by one profile never persists under its sibling.

Part of the Phase B settings-contract cutover; the legacy hooks in
queries/settings.ts keep their remaining callers until B4 deletes them.

* feat(web): store library, sidebar, and overlay preferences through the settings contract

Phase B2 of the settings-contract cutover: the query-layer preference
stores — sidebar pins, library page state, disabled libraries, library
order, and card overlay prefs — move off the legacy string-valued
/settings endpoints onto the canonical values API, using generated
SETTING_KEYS and each definition's declared scope (profile for pins,
visibility, order, and overlays; profile_device for page state and the
remember toggle).

Values are now written as typed JSON matching the contract schemas
(sidebar-pins.json, library-page-state.json, library-id-list.json,
card-overlays.json) instead of JSON-encoded strings, so the encoding the
migration produced keeps validating. Every parser accepts both the
canonical object value and the legacy string encoding, so nothing breaks
while caches or older rows still hold strings.

Semantics preserved deliberately:
- Sidebar pin toggles keep their optimistic update with the
  revision-guarded rollback, now layered on the effective-settings cache
  entry (effectiveSettingsQueryKey is exported for exactly this).
- The remember-library-pages toggle clears the device override to
  inherit again rather than storing the default, via
  useClearSettingValue; the canonical DELETE's 404 for "nothing stored"
  is treated as already-done, matching the legacy delete's idempotency.
- Overlay prefs keep the admin default / kill-switch layering: the
  contract default null means "no preference expressed", which is what
  lets /settings/overlay-config defaults apply, and only a stored value
  overrides them.
- Library visibility/order keep their optimistic local state with
  rollback on error; ids are normalized client-side with the same rules
  library-id-list.json enforces.

parseDisabledLibraryIDs/parseLibraryOrder collapse into one
parseLibraryIDList (they were byte-identical), and the serialize helpers
disappear with the string encoding. Legacy hooks in queries/settings.ts
stay for the remaining consumers until B4.

* feat(web): write playback, subtitle, and library preferences at canonical scopes

The settings screens and the player panels were the last web surfaces still
speaking the legacy string API, and each carried its own idea of where a
preference lives. Playback and subtitle behavior wrote profile columns through
PUT /profiles; auto-play and next-up wrote untyped strings; subtitle appearance
went through three bespoke routes that existed only because the string API had
no way to express an object-valued setting per device. All of them now read one
batched effective resolution and write typed JSON at an explicit scope.

Where each preference lands follows the manifest rather than the endpoint that
happened to hold it:

  - Playback and subtitle defaults, and next-up mode, write at profile.
  - Subtitle appearance writes playback.subtitle_appearance at profile_device,
    replacing /settings/subtitle_appearance/effective and the PUT/DELETE pair on
    /settings/device/subtitle_appearance. One hook now owns that value for the
    settings screen, the in-player panel, and the cue renderer, which before
    each parsed the effective response separately.
  - Per-library edits write at profile_library with the library identity, one
    key at a time. The legacy endpoint replaced a composite row, so clearing one
    field meant re-sending the other three and losing any concurrent change to
    them; independent per-key writes have no such coupling, and "inherit" is a
    delete rather than a sentinel.
  - The in-player series choice splits along the line the contract draws:
    language and mode are preferences and move to profile_series, while the
    track index and signature stay on /subtitle-prefs because they identify a
    concrete track rather than expressing a preference.

Controls render from the generated SETTING_DEFINITIONS. The hand-written
registry beside it had drifted — it declared several profile-only keys as device
overrides, and disagreed with the manifest about the bounds of two sliders — so
the display helpers now derive control shape, options, bounds, and the
device-overridable key list from the contract. (Deleting settingsManifest.ts
itself is B4; nothing outside its own test imports it any more.)

Two follow-on fixes fell out of reading the contract rather than the registry.
playback.auto_skip_recap and playback.auto_play_next_preview are declared at
profile_device but only the intro override was ever consulted, so a device
override on either silently did nothing; the player resolves all three now.
And per-library "Original Language" is gone: the contract types these as BCP 47
tags, and the phase-A migration already rejects "original" at profile_library,
so offering it would have written a value the server refuses.

Risk worth naming: LibrarySettings decides "overrides" from the resolved source
rather than by comparing values, which is what keeps three distinct cases apart
— a library row holding the same value as the profile is still an override, and
a library row holding null is an explicit "no subtitles" rather than an absent
choice. A screen that compared values would collapse the first into "inherits"
and the second into "unset".

* feat(web): refresh settings from the user_settings channel

A canonical settings write reached only the tab that made it. The server
already publishes user_settings.changed on every write and delete, but no
web client subscribed, so a preference changed on a phone or by an admin
sat stale here until a manual reload or the 5-minute staleTime expired.

Subscribe the channel and treat the frame purely as an invalidation
signal. The payload carries the key, the scope and the profile — never a
value, because admins receive other accounts' user-scoped events and a
value there would leak private settings. Marking the value queries stale
lets react-query refetch only what a mounted screen is reading, and a
burst of writes coalesces into one fetch per key rather than one per
event.

A profile-addressed change to a profile other than the signed-in one is
dropped: it cannot alter what this tab resolves. Account-scoped changes
carry no profile and always invalidate.

* refactor(web): render settings from the generated contract

web/src/lib/settingsManifest.ts was a hand-written table of labels,
controls, defaults and bounds sitting beside the generated contract, and
it had already drifted: it declared profile-scoped keys as device
overrides, disagreed with the server on the type and range of several
keys, and enumerated a language subset narrower than the one the player
speaks. lib/settingsDisplay.ts has derived all of that from
SETTING_DEFINITIONS since the contract landed, and nothing but the
manifest's own test still imported it.

Delete the manifest and its test. The one piece it owned that the
contract cannot express is the language list — language settings are
typed as BCP 47 rather than as an enum, so there is no member list to
render — which moves to lib/languageOptions.ts and is now derived from
the shared player language list. Two shapes ship: NAMED_LANGUAGE_OPTIONS
for a control that spells its own unset entry, and LANGUAGE_OPTIONS with
the leading "no preference" row for a nullable setting.

The per-library editor's LANGUAGE_OPTIONS re-export goes with it, so
every language dropdown in settings now iterates one list in one shape.

* fix(web): show canonical device overrides in admin devices

The device detail panel read its override rows from
GET /admin/devices/{user}/{device}, whose `settings` array still comes
out of the legacy user_device_settings table. The settings-contract
migration folded that table into user_setting_values and nothing writes
to it any more, so an override created since the cutover — including one
the admin had just saved through this very panel — was invisible here,
while the migrated rows stayed visible. The panel's own writes go to the
canonical route, which made the list look like it silently dropped
edits.

Read the overrides from the canonical values API instead, filtered to
device scope and to this device. Both storage generations show, because
the migration moved the legacy rows into the same table. The detail
endpoint is still the source for registration metadata — device name,
owner, which profiles have used it — which is not a setting and has no
canonical equivalent.

The override count and last-updated readouts move to the canonical rows
for the same reason: override_count is computed over the legacy table and
would disagree with the rows rendered underneath it. "Reset all for
device" has no bulk canonical route, so it keeps issuing one delete per
key, now over the keys that actually exist. The reset button also takes
the profile id from the tab rather than from its first row, which a
profile registered on the device with no override yet does not have.

* refactor(web): delete the legacy settings hooks

hooks/queries/settings.ts spoke the string-only registry API: every
value a string, scope implied by which function you called, and an
unknown key silently accepted. Phase B moved every consumer onto the
canonical value hooks, and the last importer left was the file's own
test — so both go together, along with the client functions they were
the only callers of.

hooks/queries/libraryPlaybackPreferences.ts goes with them. It wrapped
GET/PUT/DELETE /library-playback-prefs, which LibrarySettings replaced
with profile_library-scoped canonical writes; nothing in web has called
it since. The server route stays for now — the Android and Apple clients
may still use it — but the web type and query keys have no reason to
linger.

settingsKeys keeps only `all` (the prefix the canonical invalidation
targets) and the plugin entries, which are a different system. The
list/detail/deviceDetail/effective builders described the registry's
cache layout and had no remaining callers; effectiveSettingsQueryKey in
settingValues.ts owns the canonical shape.

hooks/useSettingsForm.ts is deliberately untouched: it edits admin
server_settings through /admin/settings, which is a separate surface
from the per-user contract, and has more than twenty live consumers.

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

* fix(web): review pass over the phase B adoption

Phase B moved the web client onto the canonical settings surface. Three
scope mistakes slipped in, all of the same shape: a value written at a
scope no UI can reach, shadowing the one the user can edit.

Auto-play next. The post-roll toggle wrote profile_device while Settings →
Playback wrote profile, and the contract resolves the device row above the
profile row. Turning auto-play off in the player therefore made the
settings switch permanently inert — it saved a profile value the device row
kept shadowing and snapped straight back, with no web affordance able to
clear the device row. Both surfaces now share useAutoPlayNextSetting, which
writes the profile and clears any device row (also the only way a migrated
per-device override becomes reachable). Before Phase B both writers used
useSetDeviceSetting, so they could not disagree; this restores that
invariant at the scope the rest of the Playback screen edits.

In-player subtitle picks. handleSubtitleChanged wrote three canonical keys
at profile_series, the top of the resolution ladder, while "Auto" on the
item page still deleted only the legacy /subtitle-prefs row — so the reset
silently stopped working and the abandoned language kept resolving for
every episode of the series, forever. One of the three,
show_forced_subtitles, was worse: the player has no forced-subtitle
control, so the value it wrote back was the *resolved* one, which for a
viewer who never expressed a preference is the contract default. That
pinned the default above the profile-scope toggle on the Subtitles screen.
The written set now comes from SERIES_SUBTITLE_SETTING_KEYS — language and
mode only, both derived from the user's actual choice — and
useDeleteSubtitlePreference clears exactly that list, so the writer and the
reset cannot drift. show_forced_subtitles still rides the legacy composite
row, which is keyed to a concrete track selection and is not part of the
canonical ladder.

Admin user settings. The tab now lists every non-device canonical row,
which includes the object-valued profile settings (sidebar pins, card
overlays, disabled libraries, library order, custom theme vars). It gated
only on `definition`, and controlKindFor has no `object` branch, so those
fell through to RegistrySettingControl's select — rendering a user's pins
as a one-entry "Unset" dropdown whose only option nulls them. It now uses
the same isStructuredSetting guard the device tab got, routing them to a
raw JSON editor.

Tests: each fix has a test that fails without it, verified by reverting the
fix in place. The auto-play and subtitle tests resolve through
lib/settingsResolve rather than a canned answer, so the scope-precedence
assertions exercise the real ladder.

* fix(settings): serve profile preference fields from canonical resolution

PUT /settings/values?scope=profile writes only user_setting_values, but
GET /profiles still served the legacy user_profiles columns. A preference
saved through the canonical API was therefore invisible in every profile
DTO reader on every platform — Apple's shipped build reads exactly those
fields — while profiles_settings_sync.go mirrored one way only, legacy
column write to canonical row.

Serve those five fields (language, preferred_metadata_language,
subtitle_language, subtitle_mode, show_forced_subtitles) by resolving
their canonical keys through the settingsresolve seam at profile scope,
falling back to the contract default rather than to the stale column.
This matches the cutover direction taken everywhere else: the legacy
columns stay written but stop being read, so "clear this preference"
cannot resurface a pre-cutover value the one-time backfill already
converted. The write paths that accept these fields and mirror them are
unchanged; this is read-side only, and the DTO's field names and types
are untouched.

Resolution is batched. A profile list serves the whole household, so
SettingResolutionQuery.ProfileID becomes ProfileIDs and the new
Resolver.ResolveProfiles ranks every profile against one candidate set —
one store read per list request instead of one per profile. Both backends
carry the widened predicate and the shared storetest conformance suite
gains a household case, so they cannot drift on it.

quality_preference stays column-backed: the legacy column is one compound
value while the contract splits it across playback.preferred_quality and
playback.max_bitrate_kbps, so there is no lossless read. The auto_skip_*
and auto_play_next_preview fields stay column-backed too — the sync path
never mirrored them, so their canonical rows can lag the columns.

* fix(web): repair CI findings after the main merge

CI runs checks the local loop does not: golangci-lint (not installed
here) flagged two unchecked Close errors in the new websocket test, and
tsc -b (the tests were only vitest-run locally) rejected strict
indexed-access in four test files touched by the review passes. The
merge also brought main's onboarding tour, whose SettingControl wrote
through the legacy useSetSetting hook this branch deletes — it now
writes the canonical scoped mutation, re-typing the tour's string values
through the generated contract like the admin surface does.

* style(settings): satisfy the incremental lint pass

golangci-lint reports findings incrementally, so these three surfaced
only after the previous fix: errors.Is for the pgx.ErrNoRows compare
(wrapped errors), and named constants for the repeated "values"
response key and the "usersettings" prefs id goconst flagged.

* fix(database): pin the read value when deleting moved displayprefs rows

Under READ COMMITTED the move's DELETE takes its own snapshot, so during
a rolling deploy an old-binary instance could update a jellycompat row
between the migration's SELECT and its delete — and the (user_id, key)
predicate would destroy the newer value after copying only the older
one. Naming the value the transaction actually read makes such a row
survive as a stranded legacy row instead, the same disposition a
late-inserted row already had.

Extends the concurrent-write migration test to commit an update to an
already-read row during the stall and assert the newer value survives.

* fix(api): make canonical mutation writes honest under failure

Three review findings on the canonical settings endpoints:

- Idempotency receipts were recorded via defer, so a failed upsert
  still left a receipt and the client's retry replayed a success for a
  write that never happened. The receipt is now written only after the
  upsert lands, and it stores the actual response — revision and
  updated_at included — so a replay is byte-identical instead of a
  reconstruction of the input with revision 0.

- The mutation envelope accepted trailing JSON after the first
  document, leaving the interpreted mutation parser-dependent. The
  decoder now requires EOF after the envelope.

- Resolving a device-aware key without X-Silo-Device-Id silently
  skipped every stored device override and passed the profile fallback
  off as the effective value. The effective endpoint now fails closed
  with 400, matching the write path's existing requirement.

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

* fix(settings): stop the contract rejecting values shipped clients store

Four bounds in the contract were narrower than what a shipped client
already produces, so real stored preferences would fail validation or
be quarantined at migration:

- The BCP 47 grammar rejected extlang tags (zh-cmn) and private-use-only
  tags (x-private) the legacy length-only validator accepted, turning an
  existing 204 into a 400. The pattern now covers both, and
  NormalizeLanguageTag cases a script correctly after an extlang and
  leaves private-use content lowercase.

- subtitle_appearance.fontFamily allowlisted ASCII, contradicting its
  own description: Apple clients store CTFontManager family names
  verbatim and those are routinely CJK. The pattern now excludes unsafe
  characters instead of allowlisting ASCII.

- theme-var-overrides capped CSS values at 128 characters, which real
  multi-stop gradients exceed; the web importer stores them unchecked.
  Raised to 1024.

Plus one tightening the review asked for: card-overlays.order now
declares uniqueItems, matching library-id-list, so an overlay cannot be
rendered twice.

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

* fix(userstore): reject non-canonical identities and bound resolution batches

Three review findings on the canonical settings storage layer:

- SettingIdentity.Validate trimmed ids only to check emptiness, so a
  padded id like " p1 " validated, persisted verbatim, and was then
  invisible to resolution queries, which bind trimmed forms — a
  silently orphaned row. Validation now rejects any id that is not in
  canonical trimmed form, pinned in the shared conformance suite so
  both backends hold the line.

- The effective-values endpoint accepted unbounded library_ids and
  series_ids lists; the SQLite backend expands each id into a bound
  parameter, so a crafted batch could exhaust the host-parameter budget
  and fail the whole resolution. The request boundary now caps the
  combined content ids at 200.

- pickForScope's doc comment promised ties broken "by the most
  specific id in the request order" while the implementation sorts by
  ascending library then series id; the comment now describes the
  actual (deliberately deterministic-only) behavior.

Plus: the pgstore conformance cleanups now assert the ON DELETE CASCADE
they rely on instead of discarding the delete error, so a dropped FK
can no longer leak seeded rows into the shared test database silently.

* fix(settings): close the discovery gaps around the canonical API

Three review findings:

- Canonical profile_device writes never touched the device registry, so
  a device that only ever wrote through /settings/values was invisible
  to ListDevices and the admin device surfaces — undiscoverable and
  unforgettable. Device-scope writes now refresh the registry from the
  request's device headers, throttled the same way the legacy route is.

- The contract spec tells clients to probe GET /settings/manifest (and
  /settings/capability), and to read a 404 as "pre-contract server";
  the router only exposed /settings/contract*. The documented paths now
  alias the same handlers.

- The plugin proxy's X-Silo-Theme header came from the legacy
  account-level user_settings.ui_theme row, so a profile's theme change
  through the canonical API never reached plugins and profiles sharing
  an account were indistinguishable. The lookup now resolves the
  canonical profile-scoped ui.theme row (falling back to the legacy row
  for stores the backfill has not covered) using the request's active
  profile.

* feat(settings): emit revision metadata in generated bindings and verify the TS one

Two review findings on the generator surface:

- The bindings dropped every introduced_in tag, so a client generated
  from revision N could not filter its pinned contract down to an older
  server's advertised revision — the promised negotiation had no data.
  The TypeScript definitions now carry introducedIn per definition,
  per scope, per enum member, and the full history of any widened
  numeric bound. (Go/Kotlin/Swift emit keys, not definition tables, so
  they only need the Revision constant they already have.)

- make verify-settings-bindings compared only the generated Go file and
  the conformance fixture, so a manifest change could merge with a
  stale web/src/lib/settingsContract.ts. The target now regenerates and
  diffs the TypeScript binding too, through the same prettier config
  the bindings target applies.

* chore: drop the accidentally committed settingsgen binary

24ee9952 checked in a 5.5 MB compiled settingsgen alongside its source.

truth and make settings-bindings runs it with go run.

* fix(settings): close the migration planner's data-loss and crash findings

Four review findings on the one-time legacy-to-canonical migration:

- A device holding both player.next_up_prompt_seconds and its
  playback.* rename canonicalized to one identity, and both backends
  insert bare — a unique violation that failed NewUserDB (SQLite) or
  aborted the goose migration (Postgres). Plan now ends with a
  deterministic dedup keyed on the canonical identity; a canonically
  keyed row beats a renamed alias, since the runtime writes the
  canonical spelling first and only best-effort-deletes the alias.

- The four auto-skip profile columns (auto_skip_intro/credits/recap,
  auto_play_next_preview) were never read, so an explicit true silently
  became the contract default false. They now migrate — explicit true
  only, so an untouched false column does not become a choice.

- Profiles with language 'en' emitted no playback.audio_language row
  because the column default was suppressed, but that default WAS the
  effective behavior: the old playback path preferred English, while
  the canonical null default skips language matching entirely. English
  now migrates as an explicit row. The other suppressed defaults stay
  suppressed — their empty-string defaults already meant unset.

- Stored v1 card_overlays documents were quarantined because the
  planner validated them against the v2-only schema; the web parser has
  upgraded v1 at read time all along. The planner now applies the same
  v1-to-v2 upgrade before validation.

* fix(settings): delete canonical library-scoped values with the library

The canonical settings schema deliberately has no FK on library_id or
series_id, and the migration comment promised the owning delete paths
would clean these rows up — but nothing called
DeleteSettingValuesForLibrary/-Series outside stores and tests, so a
deleted library left orphaned profile_library preferences in every
user's store forever.

Adds userstore.SettingValuesCleaner, a per-user best-effort sweep in the
mutation-sweeper's mold, and wires it into the library delete job. The
series-side cleanup is exposed on the same cleaner for the scanner's
orphan pruning to adopt; series have no single delete executor today.

* fix(settings): keep off-step playback speeds working until cutover

The legacy device endpoint gained step enforcement mid-branch, turning
an existing in-range PUT of 0.26 from 204 into 400 — a behavior change
on a live /api/v1 endpoint before the coordinated break, which the v1
rules forbid. The legacy validator is back to range-only; the typed
mutation endpoint keeps enforcing the manifest's step.

The migration planner now snaps stored off-step numbers onto their
definition's step grid instead of quarantining them: a stored 0.26 is a
real preference, and every client's stepper was going to snap it on the
next write anyway.

* fix(settings): serve canonical values to the readers the cutover stranded

Four P1 review findings where the web writes canonical rows the server
never reads — and the legacy keys those readers use are now unwritable,
so the values are frozen and user edits silently do nothing:

- access.DisabledLibraryIDs and the policy viewer resolver read the
  legacy account key while the library screen writes profile-scoped
  ui.disabled_library_ids. Both now resolve the canonical profile row,
  falling back to the legacy key only when no canonical row exists.

- The sections fetcher and handler read the legacy next_up_mode account
  key while the playback screen writes ui.next_up_mode. Same ladder,
  behind one shared sections.NextUpMode helper.

- Profile creation committed the profile and then synced settings
  non-atomically, so a mid-sync failure left a profile the retry could
  not recreate (name conflict) with preferences that read as contract
  defaults forever. The create path now compensates by deleting the
  profile it created.

- The mounted legacy PUT /subtitle-prefs/{series_id} wrote only
  user_subtitle_preferences, but item detail resolves those three keys
  canonically, so a post-upgrade client's "subtitles off" returned 204
  and was ignored. The legacy handler now dual-writes the canonical
  profile_series rows, and its delete clears them.

Plus the migration's disposition for stranded Apple device-scope audio
language rows: nothing read them before the contract, so promoting them
to real overrides would change track selection at upgrade. They are
recorded in the rejects table instead of copied.

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

* fix(web): make canonical settings writes take effect

Three P1 review findings on the web half of the cutover:

- Every profile-default editor reads the resolved value but writes the
  profile row, so a device override — left by the migration converting
  legacy user_device_settings, or written by another client — kept
  shadowing the save and snapped the control back with no affordance to
  remove it. useAutoPlayNextSetting already solved this for one key;
  that logic is now a shared useProfileDefaultWriter used by the
  playback screen, the quality picker, subtitle behavior, and the four
  appearance setters. It only clears when the key is device-scopable
  and the resolved value actually came from a device row.

- The appearance cache only ever grew: when the effective response
  resolved a key to "default" — because another client deleted it —
  the namespaced entry and local state survived and kept winning the
  fallback, so a removal never reached this browser. The mirror now
  runs both ways, clearing only on an explicit default answer (silence
  is not a deletion) and only within the current identity's namespace.
  Custom theme vars and CSS do the same, except while a local draft is
  unsaved.

- The quality picker wrote the canonical two-axis keys while playback
  still derived its cap from currentProfile.quality_preference, a
  legacy compound column the canonical write deliberately does not
  mirror — so choosing a quality changed nothing about what played. The
  watch route and both item-detail pages now read
  playback.preferred_quality, falling back to the profile column until
  the settings read resolves so playback never blocks on it.

* fix(ci): repair the type error and the bindings gate's job placement

Two breaks from the previous commits:

- useTheme referenced storage.StorageKey, but storage is a value, not a
  namespace — the Web job's tsc caught what the local incremental
  typecheck had already cached past. Imported the type properly.

- verify-settings-bindings gained a prettier step, and the Go job that
  runs it has no pnpm, so the check failed on its own tooling rather
  than on a stale binding. Split the web half into
  verify-settings-bindings-web and moved it to the Web job, which has
  pnpm; verify-settings-bindings-all runs both locally.

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

* fix(settings): close the second-round review findings

Three from the review of the pushed work:

- The live profile sync omitted auto_skip_intro/credits/recap and
  auto_play_next_preview, which my own change made load-bearing: the
  player now resolves those keys canonically, so a legacy PUT /profiles
  moved the columns, returned 200, and changed nothing about playback.
  All four now mirror on write. The DTO read block keeps its shape —
  clients pin it — and its columns are what the sync keeps current.

- The effective endpoint dropped unknown keys silently, letting a
  client fill the gap with its own vendored default and present a value
  this server would refuse to store. Unknown keys now 404 by name.

- Two sidebar-pin toggles in flight at once could commit in either
  order, and the server upsert is last-write-wins, so the first request
  landing second restored the pre-toggle document. The writes are now
  chained, and each link reads the document when it runs, so a queued
  toggle sends the newest state rather than the one it was queued with.

* feat(database): make the settings-contract deploy reversible

Rolling back this release meant restoring a backup, for a reason that
was not obvious: the DisplayPreferences move deletes the jellycompat
rows from user_settings once it has copied them, and the previous
binary reads exactly those rows. An older server therefore starts
cleanly and silently serves defaults, so every Jellyfin client's saved
view preferences look reset.

The down functions were already written and correct — nothing could
invoke them. The backfill and the DisplayPreferences move are Go
migrations registered in-process, so the standalone goose CLI in the
Makefile cannot see them, and the server exposed only --migrate-only
and --migrate-status.

Adds MigrateDownTo, the --migrate-down-to flag, and a make target, plus
a rehearsal test that seeds a legacy row the way the old binary wrote
it, applies the move, rolls back, and asserts the row returns
byte-for-byte.

Documents the ordering in the spec's cutover section, including the two
caveats an operator needs beforehand: take a backup, and the per-user
SQLite backend cannot be rolled back at all — its migrations have no
down path and an older binary refuses to open a newer database, so
those installs restore from backup rather than degrade.

* fix(settings): skip legacy rows whose profile was deleted

The dev-server migration aborted on real data:

  writing playback.subtitle_appearance at profile_device for user 1:
  violates foreign key constraint user_setting_values_profile_fkey

user_device_settings carries an ON DELETE CASCADE on (user_id,
profile_id) today, but rows written before that constraint outlived the
profiles they belonged to — that install had 46 such rows across 14
deleted profiles. The planner copied them faithfully and the canonical
table, which declares the same foreign key, refused them; because the
backfill runs in one transaction, the whole migration failed and the
server could not start.

An override belonging to a profile nobody can select is not a preference
anyone can be shown or reset, so Plan now drops those rows rather than
repairing them, recording each in user_setting_migration_rejects so an
operator can see what was left behind. Account-scope rows carry no
profile and pass through untouched.

Verified by replaying that install's 514 device rows through the
planner: 9 rows would have hit the constraint before, 0 after.

Quick a7601028d9 fix(playback): fail closed on inconclusive PPS scans 2026-07-29 09:49:34 -04:00
CoffeeKnyteandQuick 9281ae61d9 fix(playback): transcode H.264 sources with conflicting in-band PPS
H.264 streams that redefine the same pic_parameter_set_id in-band with
different content cannot be safely stream-copied into an avc1/fMP4 HLS
segment: the avcC advertises a single parameter set, so VideoToolbox
(Safari/Chrome on macOS) decodes with the wrong PPS and desyncs mid-GOP,
surfacing as PIPELINE_ERROR_DECODE / kVTVideoDecoderBadDataErr (-12909).

At playback start, a bitstream scan (DetectMultiplePPSH264) runs for H.264
files on the probe-ensure path, grouping in-band PPS by id and flagging any
id carrying more than one distinct definition. The result is a runtime-only
flag (VideoTrack.MultiplePPS, json:"-") memoized per process — never written
to the database, no schema change, recomputed on the first play after a
restart.

The v3 planner and legacy resolver disqualify a copy-unsafe source from the
video stream-copy / remux ladder, routing it to a real transcode. Direct
play of the original container is left intact: decoders that reparse in-band
parameter sets (ExoPlayer, VLC, native) handle the source fine.

Part of #135.

CoffeeKnyteandQuick 7907e0c28c fix(playback): composite bitmap subtitle burn-in on the GPU for QSV/VAAPI
Bitmap subtitle burn-in (PGS/VOBSUB/DVB) ran the whole video through a
GPU->CPU->GPU roundtrip: every decoded frame was hwdownload'd to system
memory, the subtitle bitmap composited with the software overlay filter,
then hwupload'd back for the encoder. On a 1080p source that pins the
encode below realtime (~0.68x measured), so the client can never build a
buffer and rides the produced-head edge indefinitely; the same roundtrip
also intermittently crashes the QSV buffer path with SIGBUS.

Composite on the GPU instead via overlay_vaapi for QSV and VAAPI: the
decoded video never leaves its VAAPI surface and only the small,
low-frequency subtitle bitmap is uploaded. Measured ~7x realtime and
crash-free on the same file. The libass text path is unchanged (it must
stay on CPU), and NVENC/CPU keep the software overlay because overlay_cuda
is unverified on the bundled ffmpeg.

Adds QSV and NVENC bitmap burn-in tests and updates the VAAPI test to the
GPU graph.

c52ca7dd7a feat(admin): identify compat sessions and Android devices in the live session view (#495)
* feat(admin): identify Android devices by model in live session view

Android clients that send a bare default User-Agent (e.g.
"Dalvik/2.1.0 (Linux; U; Android 11; AFTKRT Build/RS8180.3729N)")
showed up as "Dalvik" in the admin live-session view, which tells an
operator nothing about the device.

Parse the model code out of the UA (the token between the last ';' and
"Build/") and map the Amazon Fire TV family and NVIDIA Shield to product
names. Unknown but parseable models fall back to "Android · <MODEL>"
instead of "Dalvik"; multi-word models like "Pixel 7" are preserved
whole. This is display-only: the session still stores the raw model code
in its user agent, and no response field or contract changes.

* feat(admin): mark Jellyfin-compat sessions with the JF pill by origin

The admin "JF" pill was derived at read time by substring-matching a
token list against the client name / user agent. A real Jellyfin
client that authenticates through the compat surface but sends a bare
User-Agent and no MediaBrowser client name (e.g. a Fire TV app) got no
pill, even though it plainly came through the Jellyfin API.

Stamp compat origin as immutable identity at session creation and carry
it through to the admin view:

- ClientInfo.IsCompat is set true in the jellycompat auth path; newSession
  copies it onto Session.IsJellyfinCompat.
- The flag rides the durable RecipeCard (next to the client metadata that
  already exists so the pill survives reconstruction) and is restored in
  ReconstructSession, so a server restart keeps the pill.
- buildLiveSessionSync -> worker.SessionSync -> a new compat_origin column
  on playback_sessions_sync (added migration); the reconciler upserts,
  reloads, and compares it so origin changes still publish and unchanged
  rows do not churn.
- The handler ORs the stored origin with the existing name/UA heuristic,
  which stays as a fallback for rows written before this column existed.

is_jellyfin_client keeps the same name and type on the wire; it is only
sourced more accurately.

8dea4b9056 fix(playback): stop a broken Dolby Vision RPU from hanging playback (#485)
* fix(playback): stop a broken Dolby Vision RPU from hanging playback

A Profile 7 source whose RPU ffmpeg cannot parse took the whole session
down. The dovi_rpu bitstream filter does not fail cleanly — it rejects
every packet while ffmpeg runs on, so one observed session emitted
376,316 stderr lines before the process was killed, no manifest was ever
built, and the client got a 503 after ~10 seconds that it showed as an
endless spinner:

  [dovi_rpu] Failed to read unit 1 (type 39).
  [vost#0:0/copy] Error applying bitstream filters to a packet:
      Invalid data found ... Invalid SEI message: payload_size too large

Whether the strip works is a property of the file, not of ffmpeg, so
SupportsDoviRPUFilter cannot answer it — but asking ffmpeg to strip two
seconds to the null muxer can, in about a second. Profile 7 sources are
probed once each on the start path and the result is cached; a source
that fails is copied without the filter, which leaves the base layer and
plays. Refusing to play at all does not.

The probe reads stderr rather than trusting the exit code: ffmpeg treats
a per-packet bitstream-filter error as non-fatal and exits 0, which is
exactly how a stream that could never start reached a live session.

Cache is keyed on path plus size so a replaced file is re-probed, and
bounded like the letterbox cache. A nil probe keeps stripping, since most
Profile 7 sources need it.

* chore(playback): use InfoContext in the rpu probe

* fix(playback): decide the DV RPU strip in the plan, not at the transport

The probe answered the right question in the wrong place. Suppressing the
bitstream filter as the transport was being built left the plan still
promising DynamicRange "hdr10", Claims.Video.HDR10 and the
dolby_vision_metadata_removed / hdr10_base_layer_preserved validated
claims, and left session.RemuxDVMode persisted as strip_to_hdr10 — so the
client was told it was getting clean HDR10 while receiving Profile 7 with
dangling RPUs, and every path that re-derives the filter from the durable
session put the hanging filter straight back:

  - HandleStartTranscode (quality change, seek, burn-in restart), which
    also re-derives it from file.PrimaryDVProfile() == 7 with no plan at all
  - the remote audio-switch restart, from updatedSession.RemuxDVMode
  - the progressive-remux transport, which plan_v3 evaluates *before* the
    HLS branches, so for many clients the broken file never reached the
    probe in the first place

The verdict is now a planner input alongside the transformation
registries: the registries answer whether the executor carries the
transformation, this answers whether the file does. A source that fails it
is never planned onto a strip route, so the plan's claims, RemuxDVMode and
every restart derived from them agree with what the pipeline can produce.
With no tone-map recipe in this tree an HDR10-only client has no route
left, so it gets a dv_conversion_unsupported terminal naming the real
cause rather than a generic HDR message; a client that can run its own DV
transformation still gets that route, with a degradation warning
explaining why the server route was dropped.

The two paths that bypass the plan entirely are gated at the executor:
legacy/auto remux neutralizes the profile exactly as it already does for a
missing dovi_rpu filter, and the explicit v3 strip recipe fails loudly
rather than emit dangling RPUs under an HDR10 claim.

The probe itself:

  - Tri-state verdict. Only a stderr-confirmed rejection is cached. A
    timeout, a cancelled request or an ffmpeg that will not start is
    inconclusive: the strip is kept and nothing is written, so one client
    disconnecting can no longer disable the strip for a file permanently.
  - Singleflight, so concurrent or retried starts of a title share one run.
  - Timeout cut to 6s, inside the budget a client waits on the manifest,
    and off the session lifecycle lock now that it runs at planning time.
  - Keyed on size and mtime as well as path and binary, so a file replaced
    in place with the same length is re-probed.
  - stderr capture bounded at 64 KiB; the markers are in the first lines
    and a rejecting filter emits a pair per frame.
  - The head-only coverage is stated rather than asserted: this catches a
    source that rejects from the first access unit, not one that breaks an
    hour in.

* fix(playback): keep the RPU probe alive when its caller leaves

The probe rode the caller's context, so a leader whose client disconnected
returned dvRPUUnknown — and CanStrip then handed that fail-open to every
follower already blocked on the shared call, even though their own requests
were still alive. One client walking away was enough to give a live session
the strip the source cannot survive, which is the hang this whole change
exists to prevent. The work was also thrown away, so the next start paid for
the probe again.

Run it under context.WithoutCancel instead. dvRPUProbeTimeout still bounds
it, so nothing is left running; a verdict reached after the leader has gone
is still correct and still worth caching. Follower behaviour is unchanged:
a follower whose own request is cancelled still leaves immediately rather
than waiting on someone else's probe.

02203d9e40 fix(playback): trust the server's media runtime end to end (#482)
* fix(scanner): reject durations that imply an impossible bitrate

The duration-plausibility rule only rejected videos of 10 seconds or less,
so a feature film that probed as 61 seconds passed untouched and persisted.
Clients then had nothing trustworthy to anchor on: Android's grow-only
duration ratchet has no floor to hold when the catalog value is wrong, so
the playback engine's growing-HLS-window duration won and a 90-minute movie
displayed as ~1 minute.

Size and duration together pin an implied bitrate, which separates the two
cases the absolute floor conflates. A genuine short clip has an ordinary
bitrate; a 100 GB file claiming 61 seconds implies ~13 Gbps. The ceiling
sits far above any real medium, so legitimate content cannot trip it — and
unlike the absolute floor, it does not false-positive on a genuine
high-bitrate short.

Also bump the repair-rule revision marker so rows judged by the previous,
weaker rule are re-checked once under this one. Without that bump an
improved rule never reaches the rows it was written for.

* fix(playback): publish source runtime in v3 plans and stop faking the copy seek window

Two defects with one root: a v3 plan described where playback sits without
ever stating how long the media is.

Add source.duration_seconds. It is the file's full runtime, never
`total - source_start` and never adjusted by timeline_offset_seconds, and it
is omitted rather than null when unknown — clients that coerce null to a
numeric default would read it as zero, the exact value this field exists to
stop them inventing. It is set in SourceDescriptorFromFileV3, the single
place every delivery already flows through, so direct play, progressive
remux, HLS remux and HLS transcode all carry it.

Until now the v3 plan omitted duration entirely, so clients fell back to the
playback engine. On an HLS copy remux the server intentionally serves
FFmpeg's still-growing playlist, so the engine reports the length produced
so far. With no server-supplied runtime to anchor on, a feature film played
back as a couple of minutes. The legacy protocol already answered this
correctly via fileDurationSeconds; this restores parity.

Separately, the copy branch published seek_window_end_seconds as the media
runtime. That made the window look *complete*, which clients read as proof
that any target inside it is locally seekable, so they native-seek past the
produced head of a growing playlist instead of asking for a reanchor. Leave
the end open: an incomplete window plus can_seek_anywhere=false routes every
seek through the server, which is what legacy did before v3 added the bound.

Advertise plan_source_duration_v1 so a client can distinguish "this server
does not populate the field" from "this server knows the runtime is
genuinely unknown" — without it, both look like an absent field and a client
cannot tell whether its own catalog fallback is still required.

* fix(web): pair the exit position with the media runtime, not the element duration

The player's exit state converts its position to media time but took the
duration from the video element, which is player-local. On a remux or
transcode stream the element only covers the window produced so far, so the
two values live in different coordinate systems.

Resuming a movie 50 minutes in makes that concrete: the exit position is
~3060s of media time while the element reports ~120s. The progress cache
then evaluates `position >= duration`, marks the item completed, latches the
watched badge, and — because completion clears the resume point — resets
position to 0. Exiting a resumed movie destroyed the resume point and
claimed it had been watched.

The server's runtime is authoritative and already expressed in media time,
so prefer it and fall back to the element only when no server value exists.
The rule moves into mediaTimeline.ts next to the coordinate conversions it
depends on, which is also what makes it testable — VideoPlayer itself has no
test harness.

8044eb84dd feat(activity): refine play-method tags and add a Jellyfin-client pill (#387)
* feat(activity): refine play-method tags and add a Jellyfin-client pill

Two related tagging improvements to the admin activity views, squashed:

Split audio transcodes into their own tag. The Play Method summary and
Server Activity popover bucketed every session by its raw play_method,
lumping real video transcodes together with video-copy HLS repackages and
having no separate tag for audio-only transcodes. Classify each session by
the per-stream decisions the backend already reports:
  - video re-encoded        -> "transcode" (yellow)
  - only audio re-encoded   -> "audio"     (red)
  - streams only repackaged -> "remux"     (blue, incl. video-copy HLS)
  - nothing touched         -> "direct"    (green)
ordered direct -> remux -> transcode -> audio across the distribution bar,
legend, method filter/sort, the per-row badge, and the Server Activity
stream counts.

Add a Jellyfin-client "JF" pill. Sessions from a Jellyfin-ecosystem client
(Jellyfin Web, Findroid, Swiftfin, Infuse, etc.) get a purple "JF" pill
next to the play-method tag. Detection is UI-only: isJellyfinSession()
positively matches client_name (set from the Jellyfin MediaBrowser auth
header) and then the raw user agent against the known Jellyfin client
tokens, mirroring the server's client-labeling list. The pill is orthogonal
to the method classification — a session can be both "transcode" and JF.

Pure UI/presentation change; no backend behavior changes.

AI-use disclosure: implemented with AI assistance (Claude Code).

* fix(web): cache-control on SPA shell so deploys bust stale UI

The frontend handler served index.html with no cache directives, leaving
freshness to browser/CDN heuristics. A stale index.html at a CDN edge kept
serving old content-hashed bundles, so a client-side hard refresh couldn't
recover — one browser would show the new UI while another showed the old.

Apply the standard SPA cache policy:
  - index.html (and SPA-route fallbacks): no-cache + a truncated-SHA-256
    ETag, so the shell is cached but revalidated on every load and answers
    an unchanged request with a cheap 304.
  - /assets/* (Vite content-hashed bundles): public, max-age=31536000,
    immutable — cached indefinitely; a new build changes the filename hash,
    which busts them automatically.
  - other stable-named bundled files (sw.js, icons, fonts): no-cache, so a
    changed service worker or icon can't stay stuck in a cache.

Caching is preserved (no no-store anywhere); only the tiny HTML shell is
revalidated, which is what busts a stale UI on deploy.

* fix(activity): compute the method bucket server-side and unify every session surface

Review follow-ups for the play-method tags (PR #387):

- The server now emits effective_play_method (additive field) from the same
  per-stream decisions that drive the badges, so all consumers — web, realtime
  popover, and the Android/Apple admin views later — agree on the bucket
  instead of each client re-reducing raw play_method. Rows with an unknown
  play_method (stale rows from older nodes) stay unbucketed rather than being
  misreported as audio transcodes off the bare transcode_audio flag; the web
  fallback classifier mirrors that and reports "unknown".
- Jellyfin-ecosystem detection moved server-side as is_jellyfin_client, owned
  next to the client-labeling rules so the two lists cannot drift; the web
  token list is gone. Adds kodi/mpv/delfin/finamp, which reach Silo only
  through the Jellyfin compat surface.
- The dashboard stream cards, stats session table, and household streams panel
  now use the same classification as the activity page and popover — they
  previously showed contradictory tags for the same live session.
- One shared method->label/color table in adminActivityPresentation.ts
  replaces the four independent copies (METHOD_META + three switches); the
  method column sort now uses the shared cost-order comparator instead of
  alphabetical; dead "copy"/"hls" order entries removed and the reachable
  "unknown" bucket is styled.

* fix(server): make SPA revalidation RFC-compliant and stop rebuilding the shell per request

Review follow-ups for the SPA cache policy (PR #387):

- Stable-URL bundled files (sw.js, icons, vendor bundles) now carry a content
  ETag. The embedded FS has no modtimes, so http.FileServer emits no validator
  of its own — no-cache alone forced a full re-download of multi-megabyte
  vendor trees on every use because there was nothing to revalidate against.
- Shell and favicon conditional requests go through http.ServeContent, which
  implements RFC 9110 If-None-Match semantics (weak comparison, ETag lists).
  The previous exact string compare never matched once a fronting proxy
  compressed the response and weakened the ETag to W/"...", silently killing
  the 304 path in the most common deployment topology.
- The rendered shell (index read + branding render + SHA-256) is cached per
  branding snapshot via the new Snapshot.RenderKey instead of being rebuilt on
  every request — the 304 revalidation that no-cache makes the common case now
  costs two header writes. The misnamed weakContentETag (it emits a strong
  validator) is renamed contentETag.

* fix(activity): show the JF pill on every session surface, not just the mobile row

Review comments on PR #387: the JF pill only rendered inside Admin
Activity's sm:hidden mobile row, so the desktop table — and the other
session surfaces that now share the method classification — never
identified Jellyfin-compat sessions.

Extract the pill into a shared JellyfinSessionPill component (renders
nothing for native sessions) and drop it into the Admin Activity desktop
client line, the dashboard stream cards, the household streams panel,
and the stats active-session table.

* fix(playback): sync real encode decisions and client identity for compat transcodes

Review comments on PR #387:

- Jellyfin HLS sessions that copy video and re-encode only audio synced as
  full video transcodes: ensureUpstreamPlayback resets transcodeAudio for the
  transcode transport method, and the TargetCodecVideo "copy" decision lived
  only in TranscodeOpts. A new SessionManager.SetTranscodeStreamDetails
  mirrors the actual decisions onto the upstream session when the transcode
  starts (local and remote-node paths, via an optional interface so test
  fakes are unaffected), so these sessions now bucket as "audio"/"remux".
- Transcode recipe cards now record TranscodeAudio derived from the opts
  (only an explicit "copy" leaves audio untouched — empty runs ffmpeg's aac
  default), so a session rebuilt after a restart keeps the same bucket.
- Recipe cards carry client name/version/user-agent, and reconstruction
  restores them, so the admin client label and the JF pill survive server
  restarts; the compat fallback card populates them from the live
  MediaBrowser request. Deliberately not projected into stream-token claims,
  where a user agent would bloat every stream URL.

* feat(api): capability endpoint for the live-session activity fields

Review comment on PR #387: effective_play_method and is_jellyfin_client are
omitempty, so an independently deployed client cannot distinguish an older
server from a supported one reporting an unknown method or a non-Jellyfin
session. GET /admin/sessions/capabilities advertises both fields plus the
closed bucket vocabulary, following the additive capability-endpoint rule
(same pattern as /collections/capabilities).

* fix(playback): treat empty target audio codec as an AAC re-encode in live state

ffmpeg defaults an empty target audio codec to AAC (appendAudioArgs), and the
new recipe logic already records that as an audio transcode — but the live
native path computed transcodeAudio=false for an empty codec, so the running
stream reported remux until a restart flipped it to audio. Extract the
predicate into playback.TranscodesAudio, share it across the live path, the
recipe card, and the compat mirror, and make appendAudioArgs case-insensitive
so the ffmpeg switch agrees with the predicate for any spelling.

Part of #387 review follow-up.

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

* fix(jellycompat): re-sync sessions after recording compat encode decisions

ensureUpstreamPlayback flushes the session (compat_start) before
ensureTranscodeSession / startRemoteTranscode record the actual codec
decisions, and that later mutation triggered no sync — so the admin view
showed a video-copy stream as a full video transcode until the periodic
reconciler ran. Trigger syncSessionsNow after the details are recorded
successfully; the helper is shared, so both the local and remote-node
paths are covered.

CoffeeKnyteandGitHub b3722dac58 fix(playback): open the listener before sweeping stale transcode dirs (#413)
* fix(playback): run orphaned-transcode cleanup in the background at startup

The native and Jellyfin-compat routers swept stale per-session transcode
dirs synchronously during NewRouter, before the listener bound. On a slow
network filesystem this blocked startup for 80+s (64 leftover dirs on the
last deploy), so restart-reconnect clients were turned away and the health
check reported the server unhealthy the whole time.

Move both sweeps into a background goroutine (StartBackgroundOrphanCleanup)
so the listener comes up immediately and the cleanup runs concurrently. The
delete logic is unchanged: same active-session snapshot and MaxTokenTTL
age-sparing, only later. A package-level mutex serializes concurrent sweeps
of the shared transcode root so the two background sweeps can't race on
os.RemoveAll.

Part of #412

* fix(transcode): background the node boot-time transcode-dir sweep

A dedicated transcode node swept leftover transcode dirs synchronously in
NewServer, before startStandaloneServer bound its listener. On a slow
network filesystem that delete blocked the node from coming online at boot,
the same startup-stall class as the main server.

Move the sweep into the shared StartBackgroundOrphanCleanup goroutine so the
node's listener binds immediately. Backgrounding required an age guard: the
sweep previously ran as a full wipe (minAge=0) with an empty active-set,
which was only safe because it completed before any request could arrive.
Run concurrently that would race a token-carried reconstruct writing into
TranscodeDir/<sessionID>, deleting segments a fresh ffmpeg is producing.
Passing MaxTokenTTL spares any dir younger than the max token lifetime —
exactly the ones a still-valid reconnect could reconstruct — while dirs
older than any surviving token (never reconstructable) are still reclaimed.

Part of #412

* feat(playback): reclaim orphaned transcode dirs periodically, not just at boot

The orphaned-transcode sweep only ran at startup on both the central server
and transcode nodes, so it only ever reclaimed dirs left by an ungraceful
prior shutdown. During a long uptime the in-memory session reapers delete the
dirs of sessions they still track, but a dir whose owning session was dropped
without its RemoveAll succeeding becomes an "untracked orphan" with no runtime
GC — on a box that runs for weeks these accumulate until the next restart.

Add StartPeriodicOrphanCleanup: an immediate background sweep followed by an
hourly re-run bound to a lifecycle context. Wire it on all three surfaces —
native API and Jellyfin-compat (via deps.AppContext) and the transcode node
(via a new Server.StartOrphanSweeper(appCtx), replacing its boot-only sweep).
When no context is supplied (tests) it degrades to a single boot-time sweep so
no ticker goroutine outlives the caller. The sweep stays age-guarded at
MaxTokenTTL, so nothing reconstructable is ever reaped.

Because the node sweep now runs during live traffic, it snapshots the live
job set (Server.activeSessionIDs) and spares those dirs by id rather than by
age alone — a long-lived session that only re-serves already-written segments
stops advancing its dir mtime, which age could otherwise misclassify. In
integrated mode the native and compat sweeps share one TranscodeDir but each
snapshots only its own manager's live set; the resulting cross-manager reap of
a >24h idle dir is bounded (rebuilds from token/recipe) and documented at both
call sites.

Jeremy SmithandGitHub 6ece120f77 fix(playback): stop orphan cleanup deleting the subtitle cache (#379)
The orphaned session sweep in CleanupOrphanedTranscodeDirs treats every
subdirectory of the transcode dir as a dead session, but the subtitle
cache lives in there too. Cache hits only bump the entry file mtimes,
never the directory's, so an active cache that had not seen a new
extraction in 24 hours looked stale and got wiped in one go. That forces
a full ffmpeg demux on the next PGS subtitle selection, which is the
exact cost the cache exists to avoid, and the transcode node's boot wipe
removed it unconditionally.

Skip the cache directory in the sweep. It validates entries on lookup
and runs its own LRU eviction, so leaving it alone is safe.

Two audio fixes on the V3 planner and transcode pipeline:

- Copied DTS in an HLS route drags Media3's audio clock (device stall
  corrections, ~0.3x pacing, frozen position reports). DTS/TrueHD/PCM
  are not HLS-native codecs regardless of the client's progressive
  decode claims, so HLS remux routes now convert them to AAC. Validated
  on the Shield: the copy-remux fallback went from ~0.3x pacing to
  exactly real time.

- Transcodes no longer hard-downmix to stereo: multichannel sources
  keep 5.1 through the AAC re-encode (384k, -ac 6), plumbed through
  TranscodeOpts, the planner result, and the transcode-node protocol
  (new optional target_audio_channels field, ignored by older nodes).

Also logs one "playback plan decided" line per V3 start (decision
reason, delivery, play method, DV profile, quality inputs) so route
selection is reconstructible from server logs alone.

075e217477 feat(playback): plan v3 routes from pooled node capabilities (#408)
* feat(playback): plan v3 routes from pooled node capabilities

Protocol v3 planning previously gated every server transformation on the
API host's local ffmpeg probe, so deployments whose toolchain lives on
transcode nodes (libx264/aac/dovi_rpu on nodes, minimal binary locally)
received conversion terminals before transport preparation ever consulted
the selected node's capabilities.

Planning now draws on two registries split by executor pool:

- Registry stays the local probe and keeps gating progressive remux
  routes, which execute in this process and can never offload.
- HLSRegistry widens availability for HLS deliveries with the pooled
  transcode nodes' advertised transformations (name and recipe version
  pinned to the local specs), fetched concurrently under a short planning
  deadline through the existing TTL cache. Failures are now negatively
  cached so an unreachable node costs one timeout per window rather than
  one per start.

The remux family picks the executor per branch: a recipe needing
transformations only nodes carry skips the progressive remux and ships
the same recipe on the HLS remux delivery instead. The local-fallback
path in prepareTransportV3 now validates plans against the local
registry's advertised set — mirroring the per-node validation — and
returns the existing retryable transcode_node_capability_unavailable
terminal when no executor can run the recipe, instead of spawning an
ffmpeg that would fail at runtime.

Deferred from PR #398 review (comment 3579105380).

* fix(playback): harden union capability planning from review

Addresses all four review findings on the capability-union feature:

- Select capability-matching nodes: plans carrying server transformations
  now restrict node selection to nodes whose advertised capabilities
  validate against the plan (nodepool.PlanSessionWith with a set-lookup
  predicate), so heterogeneous pools cannot load-balance a recipe onto a
  node that would reject it while a capable sibling exists.
  Transformation-free plans keep pure load-based selection.
- Split the capability cache by consumer: planning honors negatively
  cached fetch failures (one timeout per window), while the transport
  path fetches through them — a memoized 3s planning deadline must not
  reject an already-selected node that the 10s transport budget could
  still validate.
- Gate node-widened availability on the HLS engine: a progressive-only
  client that needs audio conversion keeps its specific retryable
  audio_conversion_unsupported terminal instead of falling through to a
  non-retryable adaptation_unavailable for routes it can never run; the
  DV strip union flag is gated identically.
- Make HLSRegistry a lazy, memoized producer: the planner only builds
  the widened registry when a route decision depends on node
  capabilities, so direct-play and other source-preserving starts never
  wait on node capability fetches (or their dead-node deadlines).

854d07cf8f feat(playback): add protocol v3 planning and recovery (#398)
* docs(playback): plan protocol v3 server implementation

* docs(playback): incorporate protocol v3 review

* feat(playback): implement protocol v3 server

* fix(playback): persist empty route diagnostics

* feat(playback): harden protocol v3 HDR routing

* feat(playback): complete protocol v3 client contract

* fix(playback): harden protocol v3 recovery

* fix(playback): restore dovi_rpu strip filter for DV remuxes

The v3 work renamed the Dolby Vision strip recipe to a dovi_split=mode=bl
bitstream filter that does not exist in stock FFmpeg or jellyfin-ffmpeg;
the probe failed closed on every deployment, disabling the new validated
DV7-to-HDR10 route and regressing the previously working dovi_rpu=strip=1
remux path from main. Restore dovi_rpu across the probe, remux and HLS
copy arguments, and the recipe-card constant.

Also from review: validate the remux DV mode for every profile (garbage
modes on non-P7 sources silently no-opped), reject preserve mode for P7
outright (a base-layer-only remux cannot preserve dual-layer DV), tag
dvhe sample entries only for the explicit v3 preserve recipe so legacy
web/jellycompat remuxes keep their pre-v3 hev1 labeling, and honor the
token-frozen DV mode in the proxy remux path instead of legacy-auto.

* fix(playback): correct v3 planner policy and contract validation

Review fixes to the v3 planner and wire contracts:

- Bar Profile 7 sources from the non-strip progressive remux route: a
  base-layer-only remux can never deliver native dual-layer DV, so the
  planner no longer emits plans claiming validated Dolby Vision while
  the executed remux drops the enhancement layer.
- Accept the device-quirks feature flag from either capability location,
  matching every other dual-location feature check.
- Treat legacy hdr_unknown rows as HDR10 for HDR10-capable clients with
  a degradation warning instead of leaving them unplayable under v3.
- Honor bandwidth_cap_kbps as a hard ceiling in every quality mode and
  wire the previously dead Metered signal into conservative auto rungs.
- Degrade to the validated source-quality route instead of a terminal
  when only an implicit quality reduction demanded an unsupported
  transcode; explicit user-selected rungs keep terminal behavior.
- Bound inner capability lists and strings; compare attempt keys exactly
  instead of case-folded; make ParseTrackIDV3 strict about canonical
  numerics; accept dvdsub/pgssub/dvbsub aliases and stop promising
  burn-in for unknown subtitle codecs; probe every h264 encoder rather
  than requiring libx264; normalize the file-level bitrate fallback.
- Evaluate subtitle renderability against the engine each candidate
  route executes on, not always media3_direct.
- Pin the with-quirks attempt-key preimage arity in the cross-language
  fixture so the Kotlin client stays in lockstep.

* fix(playback): harden v3 control-plane reliability

Review fixes to the v3 session, store, and handler layer:

- Bound concurrent replans with a slot semaphore: each replan pins a
  pooled connection for its advisory lock while issuing further store
  queries from the same pool, so an unbounded recovery storm could turn
  every connection into a lock holder and deadlock the server.
- Make CompleteReplan a real compare-and-swap (base-revision predicate,
  ErrReplanSupersededV3) and map BeginReplan insert races to a replay
  instead of a raw unique violation.
- Fingerprint start requests (request_digest column): an attempt ID
  reused with different input is now a 409-style conflict rather than a
  silent replay, and both replay paths check session liveness so dead
  sessions surface as retryable terminals.
- Pre-delete expired attempt rows on SaveAttempt so a retry during the
  cleanup window cannot wedge on an unreachable conflict.
- Align the in-memory store's semantics with Postgres and add DB-backed
  planstore tests (SILO_TEST_DATABASE_URL), including a regression test
  inserting every route-event name against the real CHECK constraint.
- Session manager: v3 route-set updates own RemuxDVMode outright so a
  replan onto an SDR source clears a stale strip mode; replacement
  reservations survive unrelated legacy stream updates; replacement
  admission excludes the replaced session explicitly instead of
  decrementing totals it may no longer be part of; the admission CAS
  loop is bounded and decider errors are logged.
- Map transient store failures to 500s instead of terminal 404/403s;
  authorize route events via identity-only projections after the rate
  limiter; keep sanitized diagnostics deterministic.
- Merge the server-computed durable plan key into replan exclusions so
  unreproducible client history cannot re-select the failed route.
- Remap tracks only when the effective edition changes (a same-file
  replan no longer switches audio to a lookalike track) and remap
  ID-only subtitle selections on edition fallback.
- Cache the v3/shadow feature flags for five seconds instead of one
  settings SELECT per playback request; stop remote transports
  best-effort when the start call times out; carry dvm/tid claims and
  the transport-scoped job identity through the legacy audio-change
  re-mint; index playback_route_events(received_at) for the retention
  delete; run store maintenance for DB-less deployments too.

* fix(transcode): reap idle node jobs and gate WebVTT conversion

- Add an idle reaper to the transcode node: a job untouched by manifest
  or segment requests for ten minutes is closed and unregistered. After
  a v3 replan retires a transport ID, a stale in-flight stream token
  could resurrect the old job via reconstruct and encode to end-of-file
  for nobody; jobs waiting on readiness count registration as access
  and are never reaped mid-wait, and reaping keeps the recipe so a
  still-valid token reconstructs on the next hit.
- Reject bitmap subtitle tracks (PGS) on the .vtt conversion path with
  415 before headers are written instead of spawning an ffmpeg command
  that always fails mid-response, and make the extract-format override
  fall back to source-driven mapping for bitmap codecs.
- Drain error bodies on non-202 node responses so the HTTP transport
  can reuse connections.
- Pin the transcode-dir cleanup separator-boundary semantics with a
  regression test (a session ID sharing another's prefix must not
  retain foreign directories).

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

* fix(playback): close v3 planner policy gaps from review

- Clamp the final transcode bitrate to bandwidth_cap_kbps: the ladder has
  no rung below 480p/1500kbps, so lower caps were silently exceeded even
  though the cap is documented as a hard delivery ceiling.
- Treat video-only media as audio-compatible instead of forcing an AAC
  conversion (or an audio_conversion_unsupported terminal) onto a file
  with no audio stream. Tracks whose codec failed to probe keep the gate.
- Only promise a bitmap subtitle sidecar for embedded PGS with an engine
  that renders embedded bitmap: external/downloaded bitmap and embedded
  DVD/DVB published artifact URLs that always failed at fetch. They now
  fall through to burn-in or its terminal.
- Accept client_video_transformations_v1 from either client_features or
  the nested context when validating client-executor transformations,
  matching the planner's dual-source reads.

* fix(playback): probe and execute DV remuxes with one ffmpeg binary

The v3 transformation registry probed the configured playback.ffmpeg_path
while progressive remux execution resolved the process-global discovery
path, so a deployment where only one binary carries dovi_rpu could plan a
server_dv7_to_hdr10 route and then fail it at stream time. Resolution now
goes through a shared ResolveFFmpegPath (configured path first, discovery
fallback — the same rule the transcode pipeline already used), the
dovi_rpu probe is cached per binary path, and the stream handler and proxy
worker pass their configured path into ServeRemuxWithDVMode.

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

* fix(playback): harden v3 replan identity and control-plane limits

- Seed failure-replan track selections from the durable current plan
  before overlaying the request: after an alternate-version fallback the
  normalized request still carries requested-edition track IDs, so a
  replan omitting unchanged tracks was rejected as a track/file mismatch.
- Remap ID-only audio selections across edition changes (parse the ID to
  an index like the subtitle remap already does) instead of leaving a
  stale file-bound ID to fail validation.
- Release the node planner reservation when a prepared remote transport
  rolls back after the node accepted the job; repeated failed starts
  could otherwise pin max-job/bandwidth budgets for the full reservation
  age.
- Size the replan semaphore below the PostgreSQL pool via a store
  capacity advisor: with max_connections at or below the fixed bound,
  advisory-lock holders could starve the inner store queries they need
  to finish.
- Contain shadow-planner panics with a recover boundary; it runs on a
  bare goroutine where an escaped panic kills the process for what is
  telemetry-only work. Document why the memory store's session lock is
  deliberately a no-op.

* fix(transcode): serialize node job teardown against reconstructs

- Look up and touch manifest/segment sessions in one critical section so
  the idle reaper cannot unregister a job between the lookup and its
  liveness refresh.
- Re-validate each reap candidate under the per-session lifecycle lock
  before closing it: Close removes the output directory, and without the
  lock it could race a token reconstruct and wipe the segments the fresh
  ffmpeg is writing.
- Take the lifecycle lock in handleStop so a stop racing a RequireReady
  start's readiness wait blocks until registration and tears the job
  down, instead of 404ing and orphaning the ffmpeg until the reaper.

c1c110e3d2 feat(playback): improve web subtitles and track selection (#362)
* fix(player): keep text subtitles in sync across copy-mode restarts and sparse cue windows

- Rebase already-loaded cues in place when streamOriginSeconds changes
  (copy-mode session restart) instead of leaving them offset by the delta.
- Stop inferring end-of-input from where a window's cues stop; only the
  known media duration marks EOF, so a dialogue gap no longer silently
  ends prefetching for the rest of playback.
- Anchor the first window fetch to the intended start position (resume
  target or pending seek) while the element still reports currentTime=0,
  and reset coverage on forward seeks past the fetched window.

* fix(playback): align encoded transcode start with the declared segment boundary

A mid-segment start (resume, seek restart, audio switch) spawned ffmpeg at
the raw seek position while labeling its first segment with the grid number,
whose synthetic-manifest start is up to one segment earlier. hls.js aligns
the first fragment's content to that declared position, shifting the whole
session's timeline late by seek mod segment_duration (0-2s): subtitles
trail dialogue by a constant per-session offset and progress/resume
positions drift by the same amount.

Snap the ffmpeg start position down to the segment boundary for encoded
sessions so declared and produced timelines match exactly; the player
still seeks to the precise requested position. Copy-mode sessions serve
ffmpeg's real manifest and keep the raw seek.

* fix(api): forward http.Flusher through response-writer middleware wrappers

Streamed subtitle extracts (and any progressive response) flush per chunk
via an http.Flusher assertion, but none of the status-capturing middleware
wrappers implemented Flush, so the assertion failed and cues sat in Go's
response buffer until ffmpeg finished. On large remuxes where a 600s window
takes 20s+ to demux, captions appeared only when the whole window completed
instead of within the first seconds.

Give every wrapper a Flush() (satisfies plain assertions, including chi's
Compress) and Unwrap() (satisfies http.ResponseController). The jellycompat
image-proxy tag rewriter flushes only in passthrough mode since it buffers
JSON bodies for rewriting. Regression test asserts the API chain forwards
Flush end to end.

* feat(player): PGS subtitles honor size, position, and background settings

Port the tvOS/iOS bitmap-cue styling to the web player. libpgs now decodes
in worker mode but draws to a hidden source canvas on the main thread; a
compositor detects cue regions from the frame's alpha channel and re-places
them on a visible overlay canvas per the shared subtitle appearance
settings: size scale (with the 0.85 authored-size compensation), vertical
position preset (dialogue-band cues only — floating signs keep authored
placement, matching the Apple implementation), and the background box.
Font family, text color, and outline are baked into the source pixels and
remain inapplicable.

* fix(player): anchor PGS position presets to the text overlay's reference frame

The initial port used silo-apple's 30/1080 bottom margin and video-relative
lower-third/top anchors; the web text overlay anchors to a 16:9 reference
frame with 7%/18% offsets that extends into the letterbox for wide content.
Use the same anchors so PGS dialogue lands exactly where SRT text does.

* feat(player): size PGS cues to match the text subtitle line height

Replace the authored-size ladder (0.85 × font-size ratio) with per-cue
text-line matching: the region detector reports the tallest text line inside
each cue, and the compositor scales the cue so one line of bitmap text
renders at the same pixel height as the SRT overlay's font at the current
preset. Authored size differences between discs no longer leak through;
upscaling is capped at 2.5× to keep small bitmaps from going blurry.

* feat(subtitles): opt-in windowed PGS extraction to cut mid-file load latency

PGS extracts always demuxed the source from byte 0, so starting a large
remux mid-file meant minutes before the first bitmap cue. The web player
now opts in to windowed extraction (?windowed=1&position=&duration=) and
re-points libpgs at a fresh window on seeks and near coverage end; ffmpeg
input-side -ss with -copyts keeps absolute source timestamps. Without the
explicit opt-in the endpoint behaves byte-identically, so Apple/Android
and other single-fetch consumers are unaffected. ASS remains
unconditionally non-windowed (its header only exists at offset 0).

* feat(playback): cache extracted PGS subtitle tracks

Every selection of an embedded PGS track re-ran a full ffmpeg extract
that demuxes the entire source file from byte 0 — minutes for a large
remux — and responses were Cache-Control: no-store, so repeat
selections, re-watches, and multiple viewers all paid full price.

Add a disk cache for full-track .sup extracts under
<transcode_dir>/subtitle-cache, created lazily:

- Keyed by source path hash + subtitle stream ordinal + source
  mtime+size (encoded in the filename), so a replaced source file
  implicitly invalidates its entries; the source is stat'ed on every
  lookup.
- Cache miss: ffmpeg stdout is teed to the response (first viewer
  still streams progressively, first-byte latency unchanged) and into
  a temp file that is fsynced and atomically renamed into the cache
  on clean ffmpeg exit. Any error — ffmpeg failure, client disconnect,
  tee write failure, or the source changing mid-extract — discards
  the temp file, so a partial entry is never served.
- Cache hit: served via http.ServeContent (Range support,
  Content-Length, Last-Modified from the source mtime) with a
  revalidatable Cache-Control instead of no-store.
- Concurrent requests for the same in-flight track run their own
  uncached extract (mutex + in-flight key set) rather than blocking
  on another client's connection.
- Scan-on-commit LRU eviction under a 2 GiB cap (recency tracked by
  bumping entry mtime on hit; atime is unreliable under relatime),
  plus sweep of crash-orphaned .part temp files.
- Windowed PGS requests (?windowed=) bypass the cache in both
  directions: their output covers only a slice of the track.

Both the integrated API handler and the standalone proxy subtitle
path share the same playback.SubtitleCache.ServeSUPExtract helper.
VTT (already windowed and fast) and ASS (small) stay uncached. No
API surface change.

AI-use disclosure: implemented with Claude Code.

* fix(playback): check Close error returns in subtitle cache paths

Silence errcheck on the cache-hit defer and the test's simulated
disk-full Close.

AI-use disclosure: implemented with Claude Code.

* feat(playback): warm PGS cache in background and window from cached track

Windowed PGS requests bypassed the cache entirely, so every window fetch
re-demuxed the multi-GB original file. Now a windowed miss kicks off a
detached background warm (full-track extract into the cache, at most 2
concurrent server-wide, coalesced with client-driven fills), and once the
entry exists windowed extracts read the 15-80MB cached .sup instead —
seeks and re-enables become near-instant after the first load. Verified
empirically that ffmpeg preserves absolute PTS when windowing a sup input.

* feat(player): hold playback while PGS subtitle cues load

When a PGS track is enabled (or a seek lands outside the fetched window),
extraction takes seconds and dialogue could play unsubtitled. The player
now pauses until the renderer's parsed data covers the playhead — tracked
via libpgs' parsed-timestamp watermark, the exact predicate it renders
by — showing a "Loading subtitles…" indicator after 500ms. User
play/pause always wins over the hold, a 20s safety timeout prevents
stranding playback, and background prefetch never pauses. If future
libpgs versions reshape the observed internals the hook degrades to the
old play-through behavior.

* perf(player): shrink uncached PGS window to 600s

Draining a windowed extract from the source reads the full interleaved
container across the window (~1GB per 100s of remux on measured
hardware); a 3600s window cost ~12GB of reads per fetch while cold. Once
the server cache is warm a window costs milliseconds regardless of size,
so smaller windows only add trivially cheap re-fetches.

* feat(subtitles): burn in PGS/bitmap subtitles for the web player

The web player rendered PGS client-side via libpgs, which required
extracting the .sup track — a cold ffmpeg demux that took seconds even
windowed, since c:s copy still reads the whole interleaved container up
to the playhead. Every other server (Plex, Jellyfin default, Emby) burns
image subtitles into the video instead, and that is the only path with
no per-seek extraction cost.

Selecting a bitmap subtitle (PGS/DVD/DVB) now restarts the transcode
with subtitle_burn_in at the current aligned position, reusing the same
restart machinery as an audio/quality switch so the segment-boundary
timeline alignment holds. The server composites the decoded subtitle
onto the video with an overlay filter_complex graph (libass's subtitles=
filter is text-only); overlay runs at native resolution before any
target scaling, and hardware pipelines round-trip through CPU like the
text path. Burn-in forces a video encode, so copy-video recipes are
upgraded to h264 both client- and server-side.

Text subtitles keep the instant, styled, client-side path. The .sup
streaming endpoints, cache, and windowing are retained for the Apple
client, which renders PGS natively. The now-dead web PGS stack
(usePGSSubtitles, pgsPlacement, libpgs dep) is removed.

Tradeoff: bitmap subtitles no longer honor web appearance settings
(baked into the video) and toggling one restarts the transcode
(~1-2s buffering), matching Plex behavior.

* fix(player): rebuild text subtitle track when turning off PGS burn-in

Selecting an SRT track that turned off bitmap burn-in restarted the
transcode, and the client TextTrack built in that same moment was
orphaned when the <video> element reloaded, so the subtitles never
rendered (and a seek could not recover the dead track). Rebuild the
text track once the new stream settles, gated on the burn-in-off
transition so quality/audio switches and copy-mode seek restarts keep
their subtitles without a needless re-extract.

* fix(player): render web subtitles behind the control HUD

The text subtitle overlay sat at z-20, above the controls layer (z-10),
so cues painted over the bottom HUD and cluttered the control bar. Drop
it to z-[5] — above the video, below the controls — so the HUD paints
over the cues while it is visible. When controls are hidden the whole
controls layer is opacity-0, so cues remain fully visible.

* feat(player): lift web subtitles above the control bar while it's visible

Rather than hiding bottom-anchored cues behind the HUD, raise them just
above the control bar (measured height + a small gap) whenever the bar
is visible in the foreground player, then settle them back when it
hides. The bar is a roughly fixed pixel height while the cue offset
scales with the player, so the bar is measured via ResizeObserver
rather than hardcoded. Top-anchored cues never collide with the bottom
HUD, so they stay put. z-[5] is retained as a safety so any residual
overlap tucks behind the bar.

* fix(player): coalesce same-tick transcode restarts into one dispatch

Starting playback with a persisted bitmap subtitle fired transcode/start
twice within milliseconds: the auto-start effect dispatched before
subtitle auto-selection restored the burn-in, whose effect then forced a
second start. The first request was already on the wire (no abort signal
was passed to fetch), so the server spawned an ffmpeg only to kill it
for the second start — visible in production as an ffmpeg exit error
~1ms after every such session start, and slowing time to first frame.

Defer the network dispatch by one macrotask so back-to-back restart
calls in a tick collapse into a single request carrying the final
parameters; state updates stay synchronous. Pass the abort signal into
playerFetch so a superseded in-flight request is actually cancelled,
and drop any deferred dispatch on unmount so a stray transcode/start
cannot land after the session's exit DELETE.

* fix(catalog): resolve effective subtitle defaults for movie item details

Movie pre-play subtitle selectors were missing the effective defaults
(including per-item overrides saved from a previous play) that episodes
and watch payloads already resolve. Extract applyToItemDetail/
applyToWatchDetail helpers and apply defaults for movies in
buildMediaItemDetail. The SubtitlesPopover now also eagerly loads
downloaded subtitles when the saved preference points at one so the
closed trigger's Auto summary reflects the override.

* feat(player): scale subtitle font size with the rendered video

Replace fixed rem font sizes with px values defined at a 720px 16:9
reference height, scaled proportionally with the actually-rendered
video (object-fit: contain) so subtitles keep the same relative size
as the window grows or shrinks, with a 12px legibility floor. Rename
useSubtitlePositionStyle to useSubtitleLayout, returning both the
position style and the font scale, and add unit tests for the
appearance helpers.

* fix(player): satisfy strict index checks in transcode quality test

* feat(player): let the pre-play Auto option clear the saved subtitle override

A manual in-player subtitle selection persists as an 'always' override
for that movie/series, but nothing in the UI could undo it — auto
selection stayed pinned to the chosen track forever. Choosing 'Auto' in
the pre-play subtitles popover now also deletes the stored preference
(movie content ID / episode series ID) and invalidates item details so
profile-level auto selection applies again.

* feat(player): persist pre-play subtitle selections as the item override

Choosing a track (or Off) in the pre-play subtitles popover only lived
in component state: it applied to that playback session but vanished on
returning to the detail page. Persist it through PUT /subtitle-prefs —
the same 'always'/'off' override a manual in-player selection saves —
keyed by movie content ID or episode series ID, and invalidate item
details so the effective defaults reflect it immediately.

* feat(ui): show the saved subtitle override and richer pre-play pill summaries

A stored per-item override displayed as 'Auto: <language>', hiding both
that an override exists and which track it is. The pre-play subtitle
pill now shows the resolved track directly (name with (SDH)/(Forced)
markers plus format, skipping markers the name already carries), the
matching list row gets the checkmark instead of Auto, and the Auto row
reads 'Reset to profile defaults'. Subtitle, audio, edition, and
version pill summaries also truncate much later (max-w-44/sm:max-w-64).

* fix(player): recover text subtitles from stream reloads and failed window fetches

Three failure modes could silently freeze or stop web text subtitles:

- A stream restart (seek-triggered transcode restart, quality/audio
  switch) reloads the <video> element and can orphan the programmatic
  TextTrack — cuechange stops firing and the last cue freezes on screen.
  Only the PGS-burn-in-off transition rebuilt the track. Now every
  settled stream URL change bumps the generation, and the rebuild
  carries loaded cues (converted back to source time) and window
  coverage over so it costs no refetch.
- The sliding-window fetcher committed windowEnd before the fetch ran,
  so a failed or hung window counted as covered and was never retried —
  subtitles silently stopped for up to 10 minutes. Coverage now commits
  only after the window streams in fully; failures leave the range
  uncovered and retry after a 5s backoff.
- A hung extraction (one fetch in flight at a time, no deadline) blocked
  every future window for the session. Reads now arm a 30s stall timer
  that aborts a response which stops delivering chunks; slow-but-
  progressing streams keep resetting it.

Diagnosed from a session where ffmpeg took 69s to stream one subtitle
window and a transcode restart landed mid-fetch, freezing the active cue.

b7292a9473 fix(streaming): stop killing healthy streams at the server WriteTimeout (#361)
The main API server's WriteTimeout (120s) is an absolute deadline from
request start, so every streaming response still being written at T+120s
was cut mid-body with a clean close. Clients saw multi-GB direct streams
truncate every two minutes; the Apple client's cursor-resume reconnect
absorbed most kills silently, but one landing during backpressure or a
demuxer resync exhausted its retry budget and forced a full player
teardown (visible stop + historical audio desync seeding).

Fix: internal/httpstream.RollingDeadlineWriter pushes the connection's
write deadline forward with progress via http.ResponseController — a
response that keeps moving lives indefinitely, a stalled one is still
reaped within the window (180s default, SILO_STREAM_WRITE_STALL_TIMEOUT
to override). ReadFrom delegates in bounded slices so http.ServeContent
keeps its sendfile fast path. Wired into direct play, remux, downloads,
the transcode-node proxy, and ebook serving; the server-level 120s guard
stays for every other route.

The metrics and request-logger response writers now implement Unwrap —
without it http.ResponseController cannot traverse to the connection and
SetWriteDeadline fails, silently disabling the fix (exactly what the
first dev deploy showed). A middleware-chain integration test locks the
whole path down against future wrappers missing Unwrap.

Validated on dev: 200s/512MB direct and 300s/768MB via CDN sustained
range-GETs (previously dying at 120s), zero duration_ms=120000 stream
entries since deploy.

CoffeeKnyteandGitHub a2ef26bece perf: root-cause fixes for endpoints still slow after #292 (NextUp, series badges, resume tail, subtitle fonts) (#350)
* docs(plans): root-cause analysis for endpoints still slow after PR #292

Five endpoint groups stayed slow after the home/Continue Watching/Latest
latency work shipped: Resume (110s p95), NextUp (17s p95), Latest (17s),
/Items, and the home sections routes. The caps and caches from PR #292 are
live in the deployed binary; they bounded how many rows the loops touch but
not what each underlying query costs. Documents the four confirmed root
causes (4.3M stale completed-with-position progress rows + missing resume
index, unbounded next-up anchor scan, per-episode series rollup fanout, two
index-starved history/scanner paths) with live EXPLAIN ANALYZE measurements
and the fix plan implemented by the follow-up commits.

AI-use disclosure: analysis and doc produced with AI (Claude) assistance.

* perf(catalog): bound the global next-up anchor scan to recent completions

The completed_episodes CTE in buildListNextUpQuery derived per-series
anchors from the profile's ENTIRE completed history — DISTINCT ON over 233k
rows joined to episodes for the worst bulk-import profile, then a per-series
LATERAL that scans every episode of a fully-watched series before yielding
nothing. 648 slow executions in a 19h window, 44.7s worst; this drove
/Shows/NextUp (17.1s p95) and the next-up injection on the native home
sections aggregate.

Global queries now derive anchors from the profile's nextUpAnchorMaxRows
(500) most recent completed rows — an ordered index walk on
idx_uwp_profile_completed, with the hidden-items exclusion and date cutoff
applied inside the bounded scan so hidden/old rows never consume the anchor
budget. A next-up rail surfaces ~24 series; the 500 most recent completions
cover every series that can realistically rank on it. Series-scoped calls
(the show-detail tile) keep the unbounded shape: they must anchor on the
series' last completed episode no matter how long ago it was watched, and
are naturally bounded by one series.

Measured on the live worst-case profile with the exact generated SQL:
44.7s worst / ~2.6s avg before; 10ms after (together with the one-time
stale-resume-point data repair applied directly to the deployment DB — see
docs/superpowers/plans/2026-07-06-slow-endpoint-root-causes.md).

AI-use disclosure: implemented with AI (Claude) assistance.

* perf(jellycompat,userstore): aggregate series watch-state rollup in SQL

The series Played/UnplayedItemCount badge on list rails (per-library Latest,
library browse, search results) and series detail pages was computed by
materializing EVERY episode of every series on the page
(episodeRepo.ListBySeriesIDs) and then batching per-episode progress+history
lookups in 500-id chunks. A 50-series page of an episode-heavy library
(Sports) expanded to 32,467 episode rows and ~65 sequential queries —
measured 17-18s per /Items/Latest request, and PR #292's cached Latest fast
path pays it on every response for series libraries. The same fanout made
/Items?searchTerm=... slow whenever the result set was mostly series
(Meilisearch itself answers in milliseconds).

New optional store capability userstore.SeriesEpisodeRollupStore, implemented
by PostgresUserStore as one GROUP BY e.series_id aggregate with semantics
identical to the chunked path (episode availability via episode_libraries,
hidden-items visibility on progress rows, completed-history fold, in-progress
= not watched with position > 0 — verified value-for-value against the old
semantics on a real 1,586-episode series). enrichSeriesListUserData and
enrichDetailUserData use it when present; SQLite-backed stores and rollup
query failures keep the existing chunked path as fallback.
catalog.SeasonUserDataFromCounts pins the counts-to-DTO mapping to
EpisodeRollupUserData.

Measured on the live worst-case profile against the real 50-series Sports
Latest page: ~17s of chunked round-trips before, 119ms in one query after.

* perf(catalog): bound superseded-episode completed walk to recent history

The Resume / Continue Watching superseded-episode filter loaded a
profile's *entire* completed history into memory on every request that
contained an in-progress episode: CompletedProgressSnapshots paged
user_watch_progress WHERE completed=TRUE with no upper bound. The
2026-07-06 slow-query comparison showed this surviving as a 60-116s
Resume tail even after the in-progress index landed live, because the
4.3M zeroed Plex-import rows are still completed=TRUE and were re-walked
every load.

A completed episode can only supersede an in-progress one it was
finished more recently than (the query gates on
done_progress.updated_at > ip_progress.updated_at), so only completed
rows newer than the oldest in-progress entry can matter. Compute that
cutoff in SupersededEpisodeProgressIDs and pass it to
CompletedProgressSnapshots, which — since the completed listing is
ordered updated_at DESC — stops paging as soon as it crosses the cutoff.
Import-heavy profiles whose back-catalogue predates their current
in-progress items now stop on the first page instead of paging hundreds
of thousands of irrelevant rows. Correctness is unchanged: no relevant
superseding row is excluded.

* perf(catalog): hard-cap superseded-episode completed walk at 5 pages

The updated_at cutoff added in the previous commit bounds the completed
walk on the relevance axis, but a very old in-progress entry sitting
behind a large volume of newer completions could still page deep. Add a
5-page (2,500-row) hard backstop on top of the cutoff: normal profiles
still stop on page one via the cutoff, and only the adversarial tail hits
the cap. When it engages the tail of the completed set goes unscanned, so
a superseded episode could momentarily survive on Continue Watching — we
log a warning when that happens (with profile_id + rows scanned) rather
than mis-filter silently, and it self-corrects once the stale in-progress
entry ages out of the scanned window.

* perf(playback): extract subtitle fonts in a single ffmpeg pass

Embedded ASS/SSA font extraction spawned one ffmpeg process per font
attachment, each re-opening the (usually CephFS-backed) media file. Anime
releases carry 15-47 fonts, so the per-spawn file-open cost dominated and
pushed GET /api/v1/stream/{sid}/subtitles/{track}/fonts to a 17-60 s plateau
(p95 ~33 s in the live logs).

Collapse the N spawns into one ffmpeg invocation that dumps every attachment
to a temp dir (-dump_attachment:idx path ... -i file -map 0:t? -c copy), then
read the files back. The file is opened once instead of N times, taking p95
from ~30 s to ~1-2 s with no change to output.

Safety is preserved. The 32-attachment / 32 MiB caps still apply: attachment
size is stat'd before read so an over-limit font never enters memory, and a
watchdog polls the dump dir and kills ffmpeg if its on-disk output crosses the
cap -- restoring the hard bound the old pipe-per-attachment reader enforced by
killing at maxBytes+1, so a container with oversized "font" attachments can't
fill the disk.

Part of the slow-endpoint follow-up; see
slow-query-analysis/subtitle-fonts-extraction-findings.md.

* fix(review): report enforced font-byte cap; correct doc subtitle scope

Address PR #350 review:
- dumpFontAttachments reported the maxSubtitleFontBytes package constant in
  both over-limit errors instead of the maxBytes argument the caller passed,
  so the message misstated the enforced bound whenever a different cap was in
  effect (as the tests use). Interpolate maxBytes in both messages.
- The root-cause plan claimed subtitle extraction was 'out of scope' while the
  branch actually optimizes /subtitles/{track}/fonts. Scope the out-of-scope
  note to subtitle *track* conversion and record the fonts single-pass work as
  deliverable 5.

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.

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.

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

* 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.

42602b7896 feat(policy): access groups + embedded OPA policy engine with decision audit log (#282)
* docs(policy): add OPA policy engine design spec and implementation plan

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

* 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.

Part of #272

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

* 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).

* 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=
verbose. Cursor-paginated DecisionRepository backs the upcoming admin
log viewer. Retention via partman (daily partitions) and a
PolicyDecisionLogCleanupTask honoring policy.decision_log_retention_days
(default 14). PDP emits entries per evaluation; the System owns the
logger lifecycle and settings hot-reload.

Implementation drafted by Codex (GPT-5.5) via codex exec; reviewed and
verified here (removed an unused, unsynchronized PDP setter).

* 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
verified here (seeded the FK'd test user; replaced an unchecked
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.

Part of #272

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

* 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).

(locking design verified line-by-line) and verified here.

* fix(web): satisfy tsc -b strict return typing in the Rego stream tokenizer

* fix(policy): clearer error when a decision is undefined for partial input

Vendor policies index required input fields directly, so a hand-written
simulate payload missing fields yields an undefined decision. Surface
that as 'decision X is undefined for this input (missing required input
fields?)' instead of 'empty result' — found while exercising the
simulate API against a live server.

* chore(web): set changeOrigin automatically when the API proxy target is remote

* 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.

Part of #272

* 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.

Design: docs/superpowers/specs/2026-07-02-access-groups-design.md.
Implementation drafted by Codex (GPT-5.5) via codex exec; reviewed
(composition core + fail-closed call-site audit) and verified here.

* 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.

Implementation drafted by Codex (GPT-5.5); migration guards and the
choke-point subquery reviewed line-by-line here.

* feat(web): surface the default access group

Cards show a Default badge; the group editor gains a 'Default for new
users' toggle (with copy noting existing users are never moved); the
delete dialog warns when removing the default that new accounts will
start with no group.

* 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
(metadata curation excluded). Plain downloads and requests stay on. The
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.

Part of #272

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

* 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.

Part of #272

* 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.

* fix(policy): surface decision log cleanup failures to the task manager

CleanupDecisionLogsOnce now returns the first error alongside the deleted
count so a broken partition manager or DB outage marks the scheduled task
failed instead of reporting 100% success while policy_decisions grows.

* fix(playback): log admission decider errors before failing closed

A policy-evaluation failure was silently mapped to the too-many-streams
denial, making an engine outage indistinguishable from a real limit hit.

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

effectiveDownloadUser dereferenced policy state before its nil-user check,

system was unavailable because no legacy access.NewResolver fallback was
wired like the other resolver paths.

* fix(web): address admin policy review feedback

- invalidate the version query by version_number, the key usePolicyVersion
  actually caches under
- keep the goPrevious cursor-stack updater pure (Strict Mode double-invoke)

- clamp download_transcode_allowed when downloads are disabled so groups
  cannot save a contradictory record

* fix(api): cap policy endpoint request bodies at 1 MiB

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
256 KiB source cap could reject it. Route all five through a shared
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.

Addresses review findings 6.2 and C4.

* 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.

Addresses review finding C3 (plus the same shape in
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.

Addresses review finding C5.

* 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.

Addresses review finding C6.

* fix(policy): guard activation against slow overrides and make eval timeouts observable

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.

Addresses review finding C7.

604bbf1a0f feat(playback): unified restart-resilient playback (native + jellycompat) (#174)
* feat(playback): unified restart-resilient playback via shared TranscodeManager

Make direct, remux, and native HLS transcode sessions survive a server
restart through one shared flow instead of per-method paths. A missing
in-memory session becomes a reconstruct trigger, not a 404: the server
rebuilds the session from a tiny durable recipe card plus the position the
client re-supplies on its next request.

- internal/playback/transcode_manager.go: shared TranscodeManager owning the
  transcodes map, recipe-card lifecycle, reconstruct single-flight +
  concurrency cap, LoadOrReconstructSession front door, ReconstructSession /
  ReconstructTranscode, and orphan cleanup. ~90% is logic moved out of the
  native handler (no behavior change), not new surface.
- internal/playback/recipecard.go + recipecard_postgres.go: RecipeCard with a
  PlayMethod discriminator (direct/remux/transcode; empty decodes as transcode
  for back-compat) behind a swappable, nil-safe RecipeStore interface backed by
  transcode_recipes.
- internal/playback/session.go: RegisterReconstructed inserts a rebuilt Session
  under its existing id (no UUID mint, no limit double-count, race-yielding).
- internal/playback/transcode.go: CloseProcess keeps the output dir so a
  reconstruct winner keeps serving; Close removes it.
- internal/api/handlers: drain the transcode lifecycle into the manager; wire
  reconstruct into the stream/segment serve paths; re-bind ownership to the live
  caller (refuse userID==0/mismatch); card-aware orphan cleanup.
- migrations: add transcode_recipes (expires_at TTL, filter-on-read, indexed).

Ownership stays two-factor: an authenticated caller AND a session.UserID that
matches; the card stores no secrets and identity is re-resolved per request.

Tests: recipe-card round-trip/legacy-decode/disabled-noop, RegisterReconstructed
insert/race/concurrency, close-vs-close-process dir semantics, the
LoadOrReconstructSession status matrix, and the reconstruct concurrency cap.

AI-use: implemented with AI assistance (design, implementation, adversarial review).

* feat(jellycompat): reconstruct transcodes across restart via shared manager

Bring Jellyfin (jellycompat) HLS playback onto the same restart-resilient flow
as the native path. Previously jellycompat owned a separate PlaybackHandler with
a private transcodes map and a duplicated transcode lifecycle that never grew the
reconstruct half, so an in-flight Jellyfin transcode died on restart and the next
segment request 404'd.

- Embed the shared playback.TranscodeManager and delete the duplicate lifecycle,
  so jellycompat gets reconstruct, the concurrency cap, the node-affinity rule,
  and the card lifecycle for free.
- internal/jellycompat/playback_sessions_postgres.go: DurableCompatPlaybackStore,
  a write-through cache over jellycompat_playback_sessions behind the new
  CompatPlaybackStore interface (nil pool degrades to cache-only). This persists
  the load-bearing PlaySessionId -> UpstreamSessionID mapping (plus media sources,
  route item id, seek) so it survives a restart instead of vanishing with the map.
- Write a recipe card on compat transcode start keyed by the upstream session id,
  using the native StreamAppUserID so the ownership re-bind matches; reconstruct
  the upstream session and the transcode seeked to the requested seg_NNNNN.
- migrations: add jellycompat_playback_sessions (expires_at TTL + compat_token
  index, full PlaybackSession in data JSONB).

Auth is mapped to the native user id before reconstruct so the same two-factor
ownership check and userID==0/mismatch refusal apply unchanged.

Tests: DB-gated (SILO_TEST_DATABASE_URL) durable-store round-trip proving a
session written by one instance reloads in a fresh one (the restart case), plus
a nil-pool cache-only path; existing handler tests updated to the manager.

AI-use: implemented with AI assistance (design, implementation, adversarial review).

* docs(playback): consolidate unified playback reconstruction design

Replace the three overlapping playback docs (the native Postgres
restart-resilience spec, the jellycompat plan, and the unification spec) with a
single self-contained design at
docs/superpowers/specs/unified-playback-reconstruct.md.

The doc leads with the unified design — the one-idea reconstruct model, a strong
visual flow of a restart mid-playback, the shared TranscodeManager + recipe card,
the two swappable durable stores, security, the concurrency cap and node-affinity
constraint, preconditions, and verification. The design history and rationale
(reconstruct-not-rehydrate, phased delivery, Redis-vs-Postgres, token-as-
descriptor, failure analysis) move to an appendix. It references no other md file.

AI-use: written with AI assistance.

* fix(playback): address review on restart-resilient playback

Four fixes from PR review of the unified reconstruction work:

- Rewrite the recipe card on audio-track change. HandleChangeAudioTrack only
  updated the in-memory session/transcode, so after a restart reconstruct
  resumed with the stale AudioTrackIndex/TranscodeAudio (and stale play method)
  from the start-time card. Re-save the card (direct/remux/transcode) with the
  switched state, mirroring the start-card pattern.
- Guard nil TranscodeManager in LoadOrReconstructSession and ReconstructSession.
  StreamHandler.TM is documented optional (tests/minimal setups); a missing
  session previously panicked in recipeEnabled instead of returning
  SessionMissing. ReconstructTranscode already guarded nil; make the two
  siblings consistent.
- Reject direct/remux cards in doReconstructTranscode before spawning ffmpeg, so
  a non-transcode card id can never enter the HLS reconstruction path.
- Log a non-success status from the remote transcode-node DELETE in
  CloseTranscodeSession; a 401/404/500 was previously silent.

AI-use: implemented with AI assistance.

* fix(playback): harden restart-resilient compat sessions

* feat(playback): token-carried reconstruction across restarts

Build on the shared TranscodeManager (introduced earlier in this branch) so a
playback session survives an API-server or transcode-node restart without the
client re-negotiating, and retire the Postgres transcode_recipes store in favor
of a recipe carried inside the signed stream token.

- RecipeCard encodes the byte-affecting encode parameters and rides inside the
  stream token; LoadOrReconstructSession rebuilds the in-memory Session (and,
  for integrated transcodes, the ffmpeg process) on a cold miss, single-flighted
  per session and paced by a spawn semaphore. Removes recipecard_postgres.go and
  the 20260617233705_add_transcode_recipes migration.
- transcodenode reconstructs a lost ffmpeg node-side from the forwarded token.
- TR-lease: proxy/streamauth enforce a revocation deny-marker on every served
  segment, with a 500ms Redis timeout, a bounded per-session "allowed" cache
  (3s TTL, expiry-first graceful eviction), and a degraded-fail-open counter.

Review hardening folded in:
- Manifest/segment handlers do the in-memory session lookup first and only
  verify the stream token on a reconstruct miss (token HMAC was per-segment).
- Copy-mode reconstruct never applies the encoded-only seg*dur seek, at spawn
  time or via the recovery path: RestartSeekTarget reports "unresolved" for a
  copy session whose manifest cannot yet map the segment, so the client retries
  instead of seeking to a fabricated source time.
- Crash teardown is a compare-and-delete (CloseTranscodeSessionIf returns
  whether it matched); the crash closure tears down the playback session only
  when it matched, so a session reconstructed under the same id is not killed.
- Reconstruct enforces the same per-user stream/transcode caps as a fresh start
  (RegisterReconstructedWithLimits), closing a token-replay slot bypass.

AI-use disclosure: implemented with AI assistance (Claude Code), including a
two-round multi-agent adversarial review whose findings drove the hardening.

* feat(jellycompat): node-side transcode reconstruct via shared recipe store

Make Jellyfin-compat playback sessions survive a server or transcode-node
restart by reusing the shared TranscodeManager reconstruct path and a durable
recipe store, on top of the durable compat session store added earlier in this
branch.

- Node-side transcode reconstruct goes through the shared recipe store; the
  recipe is persisted to the control-plane store (Redis) when a dedicated
  transcode node is used so the node can rebuild ffmpeg after its own restart.
- Adopt the shared manager's API (3-arg OnFFmpegCrash carrying the dead session,
  guarded CloseTranscodeSessionIf, RegisterReconstructedWithLimits).

Review hardening folded in:
- Recipe lifecycle: noderecipe.Store gains Delete, called on deliberate
  teardown (stop, method-switch discard, node stop/force-reload) so a stopped
  session cannot be resurrected by a buffered request after a node restart;
  crash paths intentionally keep the recipe so a resume can reconstruct.
- Crash closure tears down the upstream session only when the guarded transcode
  close matched, so a reconstructed successor is never left orphaned.
- Copy-mode segment recovery surfaces a retryable not-found instead of a
  wrong-position restart, matching the native and node paths.
- Durable Update is now a SELECT ... FOR UPDATE transaction, removing the
  lost-update clobber that could silently drop a transcode recipe.
- Empty-token route resolution no longer falls back to an unbounded full-table
  scan; DB expiry filters bind the injected clock; the redundant re-Get is gone.

AI-use disclosure: implemented with AI assistance (Claude Code), including a
two-round multi-agent adversarial review whose findings drove the hardening.

* docs(playback): consolidate restart-resilient playback design

Replace the superpowers spec with a single architecture record describing the
token-carried recipe card, the shared TranscodeManager reconstruct path for
direct/remux/transcode, the jellycompat durable session + node recipe store, and
the revocation-lease model with its fail-open tradeoff.

AI-use disclosure: written with AI assistance (Claude Code).

* docs(playback): correct jellycompat node-recipe rationale in comments

The noderecipe / transcode-node / jellycompat comments justified the Redis
recipe store with "a Jellyfin client cannot round-trip a token". The real
reason: the node-hop token is server-minted and could carry the recipe, but the
recipe is mutated in place under a stable session id (a /Sessions/Playing/Progress
audio switch restarts ffmpeg without re-minting the client's token) and a
third-party Jellyfin client cannot be driven to refresh a stale token, so the
node must reconstruct from a server-authoritative, node-reachable store.

Aligns the comments with docs/architecture/restart-resilient-playback.md §10.
Comment-only; no behavior change.

* refactor(playback): remove deny-lease revocation, defer to future PR

The deny-lease stream-revocation mechanism (the internal/streamauth
package, its silo:streamauth:<sid> Redis markers, the proxy Allowed()
enforcement, and the admin Stop/Terminate deny write) only ever enforced
on the offload-proxy topology and was a silent no-op on the integrated
single box and the dedicated transcode node. Rather than ship a partial
revocation feature that looks complete but isn't, remove it wholesale and
defer a uniform cross-topology revocation design to a dedicated follow-up.

Removed: internal/streamauth (package + tests); the LeaseDenier field,
StreamLeaseDenier interface, and denyStreamLease helper in playback.go;
the admin deny write; the router/main wiring; and the proxy verifyToken
Allowed() gate. The unified-reconstruct core (recipe-token,
LoadOrReconstructSession) is orthogonal and untouched.

Known limitation (now on every topology): admin Terminate and user Stop
tear down the live in-memory session and ffmpeg producer, but a still-valid
stream token can reconstruct the session until its 24h TTL expires. No
node-side byte-withholding ships in this PR.

docs/architecture/restart-resilient-playback.md is updated to mark the
revocation/deny-lease sections as deferred and to drop the overstated
"instant revocation on admin kill" claim.

* fix(playback): allow zero-caller bearer on transcode reconstruct

The authless HLS transcode delivery routes (master.m3u8 / segment) treat
the session UUID as the bearer credential, so a real request carries
requestUserID == 0. The live serve path already allows this, but
ReconstructSession hard-rejected a zero caller, so a request that worked
before a restart became SessionMissing -> 404 after the in-memory session
was gone, breaking the restart resilience these routes advertise.

Match the live-path contract in LoadOrReconstructSession: allow a zero
caller (UUID-as-bearer) and refuse only a non-zero caller that mismatches
the card owner. The reconstructed session is bound to card.UserID either
way. Adds TestReconstructSession_Ownership covering both cases.

* fix(jellycompat): re-persist recipe on local audio switch

A Jellyfin client switching audio on an integrated/local compat transcode
restarted live ffmpeg with the new track but did not re-persist
PlaybackSession.Recipe. The remote branch already re-persists via
startRemoteTranscode -> persistTranscodeRecipe. After a central restart,
reconstruct rebuilt ffmpeg from the stale Recipe.AudioTrackIndex, so the
integrated session resumed on the original audio track.

Persist the updated recipe (best-effort) after a successful Restart in the
local branch, mirroring the remote branch, so the durable
Recipe.AudioTrackIndex tracks live ffmpeg. Adds a regression test.

* fix(playback): strip stream token from proxied transcode-node URL

proxyToTranscodeNode appended the client's raw query string to the internal
transcode-node URL and logged that URL on transport failure. When a remote
transcode runs without a separate proxy node, that query carries
?st=<signed JWT> — a 24h bearer reconstruction descriptor exposing the
media path and recipe claims — placing the token into internal requests and
error logs.

Strip the "st" param before building targetURL, preserving any other query
params. The token is neither forwarded to the node nor present in the
logged URL. Header-forwarding of the token (so the node can reconstruct) is
a separate follow-up (#6).

* fix(playback): fail open on transient limit-provider error in reconstruct

During the reconstruct wave right after a restart (Postgres under peak
load), a transient limit-provider DB error was collapsed into a hard 404,
permanently stopping playback for a user within their limits. limitsForUser
wrapped any provider error, RegisterReconstructedWithLimits propagated it,
and ReconstructSession mapped every error to SessionMissing -> 404 -
indistinguishable from a genuine over-cap rejection.

Distinguish the two: tag provider errors with a new ErrLimitProviderUnavailable
sentinel and, during reconstruct, fail OPEN on a provider error (admit via
RegisterReconstructed + log a degraded warning) rather than refuse - mirroring
the reliability-first fail-open-on-dependency-error philosophy. A genuine
ErrTooManyStreams / ErrTooManyTranscodes over-cap still refuses. Adds tests
for both the fail-open and still-refused paths.

* fix(playback): forward stream token to transcode node as header

The dedicated transcode node's reconstruct path reads the stream token only
from the X-Silo-Stream-Token header, but proxyToTranscodeNode forwarded only
the node-API bearer token (and #5 now strips st from the URL). So when the
central API proxied to the node and the node self-restarted, it could not
reconstruct from the recipe-complete native token -> 404.

Capture st before stripping it from the URL, verify it at the API boundary
(streamtoken.Verify + SessionID match, mirroring the node's own check), and
forward it as X-Silo-Stream-Token. Best-effort: a missing/invalid token never
blocks the live proxy, and the token is still kept out of the forwarded URL
and logs.

* fix(playback): restart node ffmpeg on native remote audio switch

A native audio-track switch on an offloaded/remote transcode was a no-op at
the node yet returned 200 with a fresh URL: HandleChangeAudioTrack restarted
ffmpeg only when the API owned a LOCAL TranscodeSession, so for an offloaded
transcode the node kept serving the OLD audio (the node consults the token
only on a session miss). The replacement URL was also minted from identity-
only claims, so a later node restart 404'd.

For the offloaded transcode case (detected via session.TranscodeNodeURL),
POST a fresh /transcode/start to the node with the new AudioTrackIndex
(handleStart tears down and restarts ffmpeg) and mint the replacement proxy
URL from a full RecipeCard so reconstruct survives a node restart. The encode
recipe is derived from the durable session target fields plus the file,
mirroring HandleStartTranscode. A concrete SegmentDuration
(playback.DefaultSegmentDuration) is embedded rather than 0: the node's token
completeness gate treats SegmentDuration<=0 as incomplete and falls back to a
recipe store the native path never populates, which would 404 on a node
restart - the exact resilience this path provides. A failed node POST now
surfaces 502 rather than a false 200. Remux and non-offloaded (local)
transcode paths keep their prior identity-claim URLs unchanged.

Known limitation: Session does not persist the original SegmentDuration or
SubtitleTrackIndex/SubtitleBurnIn, so a remote audio switch resets subtitle
selection to none and assumes the default segment length; a client that
started with a non-default segment length will resegment on switch. Making
that state durable on the session is a follow-up.

* docs(playback): scrub stale deny-lease/revalidator comments

The deny-lease revocation mechanism and its "central revalidator" were removed
earlier in this branch, but four comments still described them as live
(transcode_manager.go, noderecipe/store.go, streamtoken/token.go,
proxy/server.go). Reword them to match the shipped behavior: ownership claims
are re-resolved at reconstruct, the noderecipe store shares Redis only with the
node-session tracker, and a sub-TTL hard cut depends on a node-side revocation
mechanism that is deferred to a future PR.

* fix(jellycompat): surface durable playback-session write failures

DurableCompatPlaybackStore.Update applied the in-memory mutation and then
swallowed every Postgres commit-failure path, returning nil. Callers that
promise restart resilience (persistTranscodeRecipe's recipe write, the
upstream-session binds in streams.go) were told the session was durably
persisted when only the cache held it, so a transient DB hiccup could leave
the next restart reloading a stale row (wrong audio track) or 404ing.

updateDB now returns the genuine DB round-trip error (begin/query/unmarshal/
marshal/exec/commit); Update propagates it while still applying the in-memory
mutation so live state stays correct. A nil pool and a genuinely absent/expired
row remain best-effort (return nil) — only real infrastructure failures
propagate, so existing rollback paths fire exactly when durability is lost.

Part of #174

* fix(playback): re-inject stream token into proxied transcode manifests

API-proxied remote transcode manifests dropped the reconstruct token from
their segment URLs, so playback died after a node or API restart. When a
remote transcode has no separate proxy node, the client loads its manifest via
the API-local path; proxyToTranscodeNode strips the signed token ("st") from
the forwarded URL (keeping it off node URLs and logs, forwarded only as the
X-Silo-Stream-Token header), and the node builds relative segment URIs from
that token-less query. The segment URLs the client received carried no token,
and the proxy only re-attached the header when an incoming segment request
already had "st" — which it never did — so a restart made those segments
non-reconstructable and they 404'd.

proxyToTranscodeNode now rewrites the manifest body at the boundary: every
segment and #EXT-X-MAP init URI gets the client-facing, API-verified token
re-appended (new playback.AppendManifestQueryParam helper), so the client's
later segment fetches carry "st" again and reconstruct after a restart. The
token still never reaches the node URL or its logs. Only 200 .m3u8 responses
are rewritten (Content-Length corrected); segments stream through untouched.

Part of #174

* fix(playback): preserve subtitle/cadence recipe across offloaded audio switch

Switching audio on a remote (offloaded) transcode with burned-in subtitles
silently dropped them, and reset a non-default segment cadence. The offloaded
audio-switch restart rebuilt the node start request from Session state, but
Session/SessionStreamState retained no subtitle or segment-duration state
(only the live local ts.Opts() and the RecipeCard did), so the branch
hard-coded SubtitleTrackIndex:-1, SubtitleBurnIn:false and
SegmentDuration:Default — signing that altered recipe into the replacement
stream token. An audio switch then changed bytes beyond audio selection, and
any later reconstruct kept the wrong no-subtitle/wrong-cadence recipe.

Persist the byte-affecting recipe on the session: SubtitleTrackIndex,
SubtitleBurnIn and SegmentDuration are added to Session/SessionStreamState,
populated at start (finalizeTranscodeStart) and on post-restart reconstruct
(ReconstructSession from the card), carried forward on every audio-switch
state update, and read back when rebuilding the offloaded node request and its
recipe card. The restart now reproduces the exact live stream. Also resolves
the M-4b non-default segment_duration reset.

Part of #174

* fix(playback): serialize transcode spawn paths with a per-session lock

Reconstruct was single-flighted only against other reconstructs, so a
restart-driven segment reconstruct racing a quality/seek/audio fresh start
could spawn two ffmpeg processes writing the same output directory at once —
segment corruption, partial-write closes, orphaned processes, and skewed
active-job accounting. The atomic register-after-spawn (GetOrRegister / the
reconstruct compare-on-register) prevented a map leak but not the concurrent
disk writers, because the losing path had already spawned. The dedicated
transcode node had the same split between handleStart and spawnReconstruct.

Add a refcounted per-session lifecycle lock to both TranscodeManager and the
node Server, held across "check existing -> spawn -> register":
- reconstruct (doReconstructTranscode / spawnReconstruct) re-checks under the
  lock and yields to any live session instead of spawning a duplicate;
- the native and jellycompat fresh-start paths take the lock around their
  spawn+register (the native path also closes any session a reconstruct rebuilt
  in the meantime so its fresh ffmpeg is the sole writer);
- the node handleStart holds it across teardown+spawn+register.
The refcount drops the map entry once no path holds/waits, keeping it bounded.
GetOrRegisterTranscodeSession is removed — the lock supersedes it and keeping a
register-after-spawn primitive would invite reintroducing the race.

Part of #174

* fix(playback): serialize restart re-spawn under the session lifecycle lock

TranscodeSession.Restart() releases s.mu across cancel -> wait-for-done ->
re-exec and spawns ffmpeg into opts.OutputDir without holding the per-session
lifecycle lock. LockSessionLifecycle's contract (fresh start, restart,
reconstruct) requires restart to hold it too, but all five callers invoked
Restart unlocked: native audio-switch and segment-recovery, compat
audio-switch and segment-recovery, and the transcode-node segment-recovery.

A restart racing another restart (audio-switch vs segment-recovery) or a
fresh-start/reconstruct could land two ffmpeg processes writing the same
segment directory -- mixed timelines, init.mp4/segment mismatch, and an
orphaned-but-still-writing ffmpeg -- the exact concurrent-writer corruption
the lifecycle lock exists to prevent.

Add RestartSessionLocked (TranscodeManager) and restartSessionLocked (node
Server) that hold LockSessionLifecycle only across the cancel->respawn
transition, re-check that the handle is still the live mapped session under
the lock, and return ErrSessionSuperseded rather than re-spawning a stale
handle. Route all five call sites through them. The lock is released before
callers wait on segments so recovery latency is unchanged.

Tests: gating (restart blocks until the lifecycle lock frees, then spawns),
concurrent-restart serialization, and superseded re-check on both the manager
(covers native + compat) and node lock owners.

a4402d4621 fix(playback): stop seek-restart churn and premature paused-session reaping (#279)
* fix(playback): stop seek-restart churn and premature paused-session reaping

Two latent defects (present since the initial migration) explain the
cross-client freezes on resume-after-pause, intro-skip, and manual seek
reported in #243:

1. Dueling transcode restarts. TranscodeSession.Restart had no
   concurrency guard, and SegmentRecoveryDecision told concurrent
   segment requests to restart again while a restart was already in
   flight (the restart window runs with running=false, so requests hit
   the restart-happy transcode_not_running branch before the Restarting
   check). Pipelined HLS segment requests therefore spawned restarts
   that kept killing the ffmpeg the player was waiting on — a 30s stall
   and another restart, surfacing as buffer-then-freeze. Restart is now
   single-flight and the recovery decision waits out an in-flight
   restart (WaitForSegment already polls politely through one).

2. Paused sessions were reaped after 2 minutes, killing the transcode
   with no revival path — every resume request then 404s. Clients that
   stop progress reporting while paused (tvOS; backgrounded web tabs)
   froze on play after a >5 minute pause. Paused grace is now 30
   minutes in both the in-memory session manager and the DB session
   cleaner.

Also unifies post-restart re-arming: the throttler and exit monitor are
re-armed via a restart hook installed at session creation and fired by
Restart itself, so the jellycompat seek path (which previously re-armed
nothing) and the audio-switch path (which re-armed only the throttler)
now behave identically to web segment recovery.

Follow-up (not in this PR): lazily revive a reaped session's transcode
on resume instead of 404ing, so even multi-hour pauses recover.

Fixes #243

* docs(playback): scope the restart-hook comment to handler-created sessions

The comment above SetRestartHook claimed the hook covers restarts from
'jellycompat seek', but jellycompat creates its own TranscodeSessions via
playback.StartTranscode in a separate registry and calls Restart directly;
those sessions never get the hook and never had throttler/exit-monitor
wiring to re-arm. Reword the comment (and the matching test comment) to
scope the guarantee to handler-created sessions.

Also fix TestRestartInvokesRestartHook to resolve `true` via PATH instead
of hardcoding /bin/true, which does not exist on macOS.

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

two preparing-download IDs collided on downloads_pkey. Use the full

* 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.

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

* 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.

fadd8ff456 feat(player): native PGS subtitle rendering via libpgs (#129)
* feat(playback): add IsPGS helper and sup streaming extract path

PGS (Blu-ray bitmap) subtitle tracks can be copied losslessly into a .sup
elementary stream for client-side rendering, so they no longer have to be
burned in. streamExtractOutput maps PGS to (copy, sup), and the seek/-t
windowing now skips PGS like ASS: both formats are fetched once and
consumed whole by their client-side renderers.

This also fixes a pre-existing truncation bug: the -t duration cap was
applied unconditionally, cutting embedded ASS extracts off at the default
600s window even though the ASS client fetches the full track.

Extract the ffmpeg argument construction into streamExtractArgs for
testability, following the buildFFmpegArgs pattern.

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

* feat(api): expose PGS subtitle tracks as .sup stream URLs

PGS tracks were filtered out of /playback/start subtitle_urls entirely,
so the web player showed no subtitles for PGS-only files (#34). Include
them with a .sup URL extension; DVD/DVB bitmap tracks stay hidden since
they still have no non-burn-in delivery path.

HandleSubtitle streams the full PGS track as application/octet-stream.
The seek/duration window is forced to zero for sup: subtitleSeekPosition
falls back to the session's last reported position even without a
?position= query, which would otherwise start the extract mid-file. The
proxy-node subtitle handler gets the same sup branch, streaming ffmpeg
output directly instead of buffering like its text paths.

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

* refactor(player): consolidate subtitle codec helpers into subtitleCodecs.ts

Rename assSubtitles.ts to subtitleCodecs.ts — the module already labeled
every codec, not just ASS — and add isPGSCodec/isBitmapCodec. Replace the
duplicated BITMAP_CODECS set in SubtitleTranslateModal with the shared
helper so codec lists live in one place.

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

* feat(player): native PGS subtitle rendering via libpgs

Render PGS subtitle tracks client-side instead of leaving them
unavailable (#34). usePGSSubtitles mirrors the JASSUB hook: when a PGS
track is active it lazy-loads libpgs, which fetches the .sup stream in a
worker, decodes display sets progressively as bytes arrive, and draws
them onto a canvas positioned over the video.

The renderer looks up the display set at currentTime + timeOffset, so
the HLS stream origin adds and the user-facing delay subtracts — a
positive delay shows subtitles later, matching VTT semantics. Offset
changes apply through the timeOffset setter without recreating the
renderer; track switches, PiP detach, and unmount dispose it.

* feat(player): prefer text over bitmap tracks in subtitle auto-select

With PGS tracks now listed, an earlier PGS track would win auto-select
over a later same-language SRT/ASS track. Deprioritize bitmap codecs
within the same source tier — text is lighter to render and styleable —
while a PGS track still wins when it is the only language match, and
forced-PGS auto-select now works.

a17529fd6f feat(config): live admin settings + truthful restart-required banner (#128)
* feat(nodeconfig): harden config watcher for integrated-mode use

- RequestReload(): non-blocking, coalescing reload nudge that runs on the
  poll goroutine, so concurrent requests can never swap a stale snapshot
  over a newer one (unlike ForceReload from request handlers)
- Skip OnChange callbacks when the reloaded config is deep-equal to the
  previous one, so the 60s poll doesn't fire rebuild/log callbacks on
  no-op reloads
- Add RedisURL to BootstrapOverrides; previously a reload clobbered an
  env-provided Redis URL in the live config
- Split reload into fetchSettings/applySettings and add unit tests

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

* feat(config): hot-reload config watcher in integrated mode

Start nodeconfig.Watcher in integrated/api mode (previously only proxy/
transcode worker modes hot-reloaded). Expose the live config to the API
and jellycompat routers via func-typed LiveConfig/OnConfigChange fields
with nil fallbacks to the startup snapshot, and wire the admin settings
update hook to RequestReload so same-process changes apply immediately
even without Redis.

No consumer reads the live config yet — conversions land separately.

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

* feat(admin): truthful restart-required banner for settings saves

The settings UI showed 'restart required' after every save regardless of
the key. The backend now classifies each key via a central registry
(internal/config/restart_keys.go) and PUT /admin/settings/{key} reports
restart_required per key; useSettingsForm only raises the banner when a
saved key actually needs a restart (and keeps it raised until restart).

The registry is conservative: every currently startup-frozen key is
marked restart-required; subsequent hot-reload conversions shrink it.
Settings read live from the settings repo (branding, overlays, markers,
download.*, ...) default to no-restart. DownloadSettings/OverlaySettings
drop their hardcoded restartRequired={false} special-casing.

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

* feat(logging): hot-reload server.log_level and server.log_quiet

Share one slog.LevelVar across the handler chain and make
logfilter.Handler's quiet-prefix list an atomic pointer shared with
WithAttrs/WithGroup clones (New previously returned the inner handler
unwrapped when the quiet list was empty, leaving nothing to update).
The integrated-mode config watcher now applies both settings live;
their keys leave the restart-required registry.

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

* feat(auth): hot-reload access/refresh token expiries

JWTService stores expiries as atomics with a SetExpiries hook; all three
instances (main API, ABS compat, jellycompat) re-apply them on config
reload. Applies to newly issued tokens; outstanding tokens keep their
original expiry. The JWT secret stays fixed for the process lifetime.

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

* feat(playback): read transcode config live at session start

The playback and stream handlers pull ffmpeg path / hwaccel / transcode
dir from the live config when starting a transcode or extracting
subtitles, instead of values frozen at router construction. Each session
snapshots the config once so its output dir and binary stay consistent.

Also fixes a real bug: playback.hw_device was parsed into the config but
never wired into the integrated-mode handler, so local transcodes always
ran with an empty HWDevice while transcode nodes honored it.

playback.transcode_dir leaves the restart-required registry (the handler
is its only consumer); ffmpeg_path/hw_accel stay restart-required until
scanner/chapterthumbs/audiobook consumers convert.

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

* feat(jellycompat): read compat identity settings live per request

System/Auth handlers take a config provider instead of the startup
snapshot, so jellyfin_compat.public_url, .server_name, and
.emulated_server_version apply without restart. server_id stays
restart-required (generate-once, baked into the resource mapper), as do
the session-store TTLs.

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

* feat(scanner,metadata,mdblist): hot-reload worker pools and API key

scanner.workers, matcher.workers/batch_size, metadata.cache_images, and
mdblist.api_key convert to atomic fields with setters wired to the
config watcher. Worker counts apply on the next scan/match cycle (the
loops read them per cycle); the MDBList key applies to the next request.

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

* feat(ai): hot-reload AI connection, models, toggles, and quotas

The shared llm.Client holds its config behind an atomic pointer
(UpdateConfig; each request snapshots once), and the subtitle/metadata
AI services gain UpdateConfig plus setters on the translator (batching)
and Whisper transcriber (ffmpeg path, chunk seconds). The router derives
their configs from shared helpers used both at construction and in
OnConfigChange callbacks, re-evaluating the chat-only-gateway transcribe
guard on each reload and warning only when it newly fires.

Everything on the AI Services page now applies without restart except
ai.max_concurrent_jobs (fixed-capacity dispatch semaphore).

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

* fix(playback): wire transcode_enabled; remove dead playback/scanner knobs

playback.transcode_enabled was parsed into the config but the resolver
always received a hardcoded true — the admin toggle did nothing. It now
reads the live config per playback start, so disabling transcodes
applies without restart.

Remove settings that were wired to nothing so 'save + restart' stops
pretending: playback.allow_hevc_encoding (resolver field never
assigned), playback.transcode_ahead_segments and
playback.segment_duration (parsed, never consumed — segment duration is
per-session from the client), scanner.file_removal_grace (DeleteMissing
is never called). UI fields removed and the config struct fields pruned
so they don't resurrect; YAML import still tolerates the legacy keys.

39ba284c9d feat(ai): shared AI core — metadata translation, Whisper ASR, per-profile language, on-view translation (#127)
* docs: design + plan for shared AI core, metadata translation, Whisper ASR

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

* refactor(ai): shared LLM client, segment translator, and job runner packages

internal/ai/llm: OpenAI-compatible chat client moved out of subtitles/ai,
plus /v1/audio/transcriptions (verbose_json) for the ASR work; one shared
retry/backoff loop for both. internal/ai/translate: the batched indexed-JSON
translation protocol generalized to text segments. internal/ai/jobrunner:
dispatch/heartbeat/reaper/cancel lifecycle extracted behind a minimal store
interface, with a semaphore shareable across job services.

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

* refactor(subtitles): consume shared AI core

LLMTranslator becomes a thin cue<->segment adapter over aitranslate; the
service delegates dispatch/heartbeat/reaper/cancel to jobrunner; the local
OpenAI client is gone in favor of internal/ai/llm. Behavior (prompts, wire
protocol, job rows, recovery semantics) is unchanged. NewService now takes
the dispatch semaphore so all AI job services can share one bound.

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

* feat(config): shared ai.* settings, metadata translation job table, localization provenance columns

ai.* connection keys (chat + optional separate ASR endpoint) load with a
fallback to the legacy subtitle_ai.* rows — those are never renamed in SQL
because encrypted values are GCM-bound to their setting key. New toggles:
subtitle_ai.transcribe_enabled, metadata_ai.enabled. Migration adds
metadata_translation_jobs, per-field provenance (provider|ai|manual) on the
localization tables, and media_folders.auto_translate_metadata.

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

* feat(catalog): localization field provenance with provider/ai/manual precedence

Provider upserts keep manual values and never blank a field with an empty
incoming value; new UpsertAITranslation/UpsertAIOverview methods write AI
fields only over empty or ai-sourced values (force adds provider, never
manual) — all enforced in single-statement SQL. Serving now merges only
non-empty localized fields onto the base item, since localization rows are
legitimately partial (AI rows carry no titles/artwork).

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

* feat(metadata): AI translation service, refresh auto-fallback, and admin API

internal/metadata/translation: job service over the shared AI core that
expands an item to its season/episode overviews, skips already-localized
fields (zero model calls on repeat runs), batches paragraphs through the
generic translator, and persists per batch with provenance-aware upserts.
MetadataService gains an AutoTranslator seam invoked after each refresh for
libraries with auto_translate_metadata. Admin endpoints under the metadata
curation guard: enqueue, list (poll), cancel; plus a status probe.

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

* feat(subtitles): Whisper ASR transcribe and transcribe_translate jobs

New WhisperTranscriber: one ffmpeg pass extracts the audio track to 10-min
16kHz mono WAV chunks (temp dir cleaned on every exit path), each chunk goes
to the OpenAI-compatible /v1/audio/transcriptions endpoint (verbose_json,
per-request timeout sized to 3x chunk duration), segment timestamps are
offset and built into wrapped cues. Chunks process playhead-first and stream
live to the requesting session. The transcript is stored as an ordinary
downloaded subtitle (provider 'transcribed'); transcribe_translate chains
the existing translator and stores the translated track as the job result.
Enqueue accepts an optional kind; status reports transcribe_enabled.

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

* feat(web): AI services settings, metadata translate action, library auto-translate, generate-from-audio

New AI Services admin page hosts the shared endpoint config (reads fall back
to legacy subtitle_ai.* values, writes target ai.*) and the three feature
toggles; the AI card moves out of Subtitles settings. The metadata editor
gains a Translate-with-AI panel with job polling and force/re-translate. The
library form gains the auto-translate toggle (threaded through the libraries
API). The player translate modal gains a From-audio mode that lists audio
tracks and submits transcribe / transcribe_translate jobs.

* style: gofmt import grouping in router and translation tests

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

* feat(catalog): per-profile metadata language and viewer-triggered description translation

user_profiles.preferred_metadata_language threads through the access scope
into catalog serving: presentation language now resolves explicit param ->
profile preference -> library metadata language (native API and jellycompat).
ItemDetail gains pending_translation_language when the viewer's language is
missing a localized overview. New metadata_ai.on_view setting (off|button|
auto) gates POST /items/{id}/translate-description: any profile with item
access may request its language, with in-flight dedup and a 15-minute
failure cooldown so page views never hammer a broken endpoint.

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

* feat(web): on-view description translation with per-profile metadata language

Profile playback settings gain a Metadata language picker (library default
inherit). Detail pages: when the server reports pending_translation_language
and metadata_ai.on_view is 'auto', the description translates on view with a
pulse animation until the refetched detail comes back localized (45s
timeout); in 'button' mode a small Translate chip triggers the same flow.

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

* fix(web): expose metadata_ai.on_view in AI Services settings

The on-view translation mode had no UI control, so it could only ever be
'off' — viewers got neither the auto translation nor the fallback button.
Adds the off/button/auto selector to the Features card, and the config
loader now warns and falls back to 'off' on a bad row instead of refusing
to start.

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

* fix(ai): clear configuration hint when the transcription endpoint is chat-only

A blank Transcription base URL falls back to the chat endpoint; chat-only
gateways reject the multipart upload with an opaque 400 that reads like a
pipeline bug. 400/404/405 transcription failures now carry a hint to set a
Whisper-compatible endpoint in AI Services.

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

* fix(subtitles): wrap ASR cue text by rune count, not bytes

Arabic/Cyrillic/Greek text is 2+ bytes per character in UTF-8, so byte-based
wrapping broke lines at roughly half the intended visual width.

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

* docs(web): steer transcription base URL hint away from chat-only gateways

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

* feat(ai): block chat-only gateways for transcription, add endpoint presets

llm.IsChatOnlyGateway (OpenRouter et al — no timestamped transcription API)
is enforced in three layers: the settings API rejects ai.asr_base_url values
pointing at one, the router disables ASR with a warning when the blank-URL
fallback would land on one, and llm.Transcribe refuses outright. The AI
Services page gains one-click transcription presets (Groq turbo/accurate,
OpenAI, self-hosted speaches) plus the mirrored client-side check, and the
settings API now also validates metadata_ai.on_view.

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

* fix(subtitles): tighten ASR subtitle sync

Three systematic timing-error sources addressed: cue offsets now use the
segment muxer's exact per-chunk start times (segment_list CSV) instead of
assuming index*chunk_seconds; the audio stream's start delay relative to the
container timeline (common in TS remuxes) is probed via ffprobe and added to
every cue; and the chunk length is now operator-tunable via
subtitle_ai.asr_chunk_seconds (60-600s, default 600) since shorter chunks
bound Whisper's within-chunk timestamp drift. Playhead-first ordering now
pivots on real chunk starts, and a beyond-end playhead starts at the final
chunk instead of restarting from zero.

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

* fix(ai): tolerate base URLs that already include the /v1 segment

Providers like DeepInfra expose their OpenAI-compatible API under a base
that contains the version segment (api.deepinfra.com/v1/openai); always
appending /v1/... mangled those. endpointURL now appends bare paths when
the base already carries /v1.

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

* feat(web): prefer self-hosted transcription in presets and hints

Preset order becomes self-hosted (recommended) -> Groq turbo -> Groq
large-v3 -> OpenAI, and the settings hint plus the job-error hint lead with
the self-hosted option. The self-hosted preset now fills the turbo CT2 model
to match the recommended speaches setup.

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

* fix(subtitles): request VAD and word timestamps for ASR cue accuracy

Without vad_filter, faster-whisper servers report wall-to-wall segment
times: cues linger on screen through silence (verified up to 91s) and
paragraph-length segments become single 400+ char cues. Request
vad_filter=true (skipped for hosted providers that reject non-OpenAI
fields and run VAD server-side) plus timestamp_granularities word+segment,
and rebuild cues from word timings: split at speech pauses, sentence ends,
text capacity, and a 7s max duration; cap word-less segments instead of
trusting their reported end; stretch sub-second cues to a readable minimum.
