The sixteen specs folded in last commit were folded because someone noticed they had gone stale, not because anything said they should be. Without the rule written down the directory drifts straight back to a mix of promises and descriptions, and neither can be trusted: you cannot tell from a file whether it describes the build or proposes a change to it. So: docs/specs/ holds only unshipped work, there is no "Implemented" resting state, and the fold-in and the deletion happen in the same commit. The template now asks for the destination architecture doc **up front**, which is a design check rather than bookkeeping — a feature that fits no existing doc usually has an unclear layer assignment, and it is cheaper to find that out at spec time. It also tells the author which half of what they are writing is durable (invariants, rejected alternatives, the defect a decision prevents) and which half dies with the file (phases, migration steps, acceptance criteria). The review checklist gains a Lifecycle section, including the case that gets lost otherwise: out-of-scope work worth doing has to be written where it will still be found after the spec is gone.
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-077, IR-033, DR-215. 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-121/122/124/125 — the player quality selector and the read-through capture |
| 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 |
|---|---|
| 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. |
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. |
