Diagnosed on a device. The likeliest explanation for "audio keeps playing after I leave the player", which is the report this line of work started from. enter_background_audio and exit_background_audio are pure bookkeeping: a boolean and a base offset. Neither confirms the audio stream opened, nor that the webview <video> came back. exit_background_audio's own comment says the element "becomes the player again once it reloads" — a future event nothing waits for, while the flag calls the swap done the moment it is invoked. Foreground the app, then leave the player before the element has reloaded, and the stop is aimed at something that does not exist yet while the audio stream keeps running. The mini player then adopts a live audio session, which is why a movie reappears as an audio track and why it is intermittent. Same defect class as DR-238 … DR-241: state asserted rather than confirmed. It is what Phase::Opening and the open generation exist for — a handoff is an open in flight, and a close during one must cancel it. Today the handoff never reaches an engine as an open at all, which is why close_during_open_never_plays passes on all four engines while the bug survives. Credit where due: the sequence came from the user reproducing it deliberately, not from the logs.
Specs index
Feature specs for JellyTau. Start a new one from SPEC-TEMPLATE.md and run it past SPEC-REVIEW-CHECKLIST.md before accepting it.
What lives here
Only work that has not shipped. Once a spec is fully implemented its design is folded into the architecture docs — which are the maintained description of the build — and the spec file is deleted. Git history keeps the original, including its rejected alternatives and acceptance criteria; the architecture docs keep the reasoning that a future change still needs.
So: a file in this directory is a promise, not a description. If you want to know how something works, read docs/architecture/. If you want to know what is planned, read here.
Status vocabulary
| Status | Meaning |
|---|---|
| Proposed | Written, not accepted. Nothing built. |
| Accepted | Agreed as the design; implementation not started or not finished. |
| Partially implemented | Some parts shipped; the spec names what is left. |
| Design authority | No code of its own — it records a decision later specs act on. |
Next free requirement ids (always re-check requirements.md before allocating): UR-079, IR-033, DR-232. Three specs below suggested ids that have since been taken by other work; each carries a ⚠️ note at the top.
Partially implemented
| Spec | What landed | What is left |
|---|---|---|
| frontend-domain-model.md | Catalog surface: MediaKind, from_jellyfin isolated, ticks → ms |
primaryImageTag → imageId (~30 sites); player/session/reporting tick math; stream.type |
| libmpv2-migration.md | LICENSE |
The libmpv → libmpv2 crate swap |
| read-through-media-cache.md | DR-126…128, DR-133…138 — cache entries are download rows; local playback of downloads | DR-122/124/125 — the read-through capture. DR-121 shipped as backend-owned stream selection and left this spec |
| scoped-search-boundary-implementation.md | Stage 1: SearchScope owned by Rust (DR-063…067) |
Stage 2: result-side grouping (GROUP_ITEM_TYPES still in searchScope.ts) |
Not started
| Spec | Blocked on / note |
|---|---|
| desktop-native-video.md | mpv draws video on every desktop platform, then the webview <video> path and hls.js are deleted. Converts a measured 7% direct-play rate toward Android's 85%. Stacked on backend-owned stream selection. |
| build-provenance.md | build.rs is still bare. ⚠️ suggested id DR-093 is taken. |
| player-facade-enforcement.md | ~60 commands.player* sites still outside the facade; no lint rule. ⚠️ suggested id DR-095 is taken. |
| windows-native-audio-backend.md | Blocked on the libmpv2 swap. ⚠️ suggested id IR-030 is taken. |
| linux-native-video-spike.md | Spike run 2026-08-21: compositing works on Linux, X11 and Wayland. G1-G6 green bar the Tauri default_vbox() half of G1. The adaptive-bitrate question it was waiting on is answered: the server publishes one EXT-X-STREAM-INF, so there is no ladder for mpv to lose (DR-229). StreamSelection (DR-225) is the contract to consume. |
Design authority
| Spec | Role |
|---|---|
| playback-backend-unification.md | Why video cannot unify onto one native engine and audio can. The audio half has since shipped on Android; Windows has not. |
| scoped-search-boundary.md | The boundary design the check:boundary rule came from. Stage 1 built. |
| scoped-search.md | Superseded in part — its "frontend only, no Rust changes" decision is the leak the boundary spec reversed. UX still current. |
