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. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * 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. Part of the playback protocol v3 neutral-contract train (steps 2-3 of docs/superpowers/plans/2026-07-30-playback-protocol-v3-neutral-contract.md). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * 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. Part of the playback protocol v3 neutral-contract finalization plan (docs/superpowers/plans/2026-07-30-playback-protocol-v3-neutral-contract.md). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * 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". Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * 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. Part of the v3 neutral-contract finalization. * chore(playback): reconcile neutral v3 with main * fix(playback): preserve subtitle intent across replans * fix(playback): retain subtitle inventory on adapted routes * fix(playback): software-decode High10 AVC for QSV * fix(playback): scale High10 frames before QSV upload * fix(playback): preserve empty subtitle inventories * fix(playback): freeze terminal attempt contract * chore(playback): name fixture contract tokens * fix(playback): close v3 conformance review gaps * chore(playback): name conformance category * fix(playback): complete v3 conformance contract * fix(playback): keep schema fixtures generated * fix(playback): emit schema-valid conformance arrays * fix(playback): omit empty replan failures * fix(web): omit empty replan failures * fix(playback): close neutral v3 contract gaps * 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". Part of #135. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(web): keep playback alive through failed replans and honest audio claims Review remediation for the neutral v3 cutover, web player: - A failed or refused replan no longer unmounts the player: the fatal error screen is reserved for loads with no adopted plan, and replan failures surface through the existing non-fatal replanError path. - changeQuality rolls its optimistic preference back when the replan is refused or errors, so a failed switch is not silently applied by the next unrelated replan and the menu shows the real active rung. - The capability probe now tests mp3/vorbis codecs and mp3/flac/ogg containers (MediaSource with a canPlayType fallback), restoring direct play for mp3 audiobooks instead of per-part AAC re-encodes. - Reanchor seeks issued while a replan is in flight coalesce and run when it settles instead of being silently dropped with the scrubber pinned to a phantom position. - Subtitle refresh/translation replans use the resume anchor while the media element has no metadata, so a subtitle_ready broadcast during startup no longer restarts a resumed stream at 0:00. - An exhausted failure-recovery chain sets a visible error instead of returning silently. Part of #135. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * 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.

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. * fix(admin): correct Android device labels --------- Co-authored-by: Quick <31828688+Quick104@users.noreply.github.com> |

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.
Part of #387 review follow-up.

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

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.

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. --------- Co-authored-by: Quick <31828688+Quick104@users.noreply.github.com> |
