User-level state for the music app, served by the platform from Postgres (not
the sidecar, which is stateless about users) under the same /api/music prefix
so the music-app account gate permits it:
- music_favorites (userId, kind, key) — kind ∈ track|album|artist, opaque path
key the server never interprets; unique per (user,kind,key), newest-first.
GET /favorites (grouped), POST /favorites (idempotent), DELETE /favorites.
- music_now_playing (one row/user) — current track + position snapshot for
resume-across-launch/device, with a light title/artist/album cache so the
resume card renders before the library index syncs.
GET/PUT/DELETE /now-playing (upsert).
Routes registered before the catch-all proxy. Tables created via direct DDL;
query layer smoke-tested against the live DB. MUSIC_API.md documents the
contract for the app. App-side wiring (heart toggles, Favorites view, player
persistence) follows next.

Each Albums/<Artist>/_discography.md (author-maintained source of truth, never
modified) is compiled into a per-artist discography.json in the cache = album
folder → normalized release type (Studio/Live/Compilation/Single/EP/…), so the
player can split an artist's album list into sections.
- indexer.ts: parse the md table, normalize the Type (EP?→EP, Compilation (VA)→
Compilation, …), write discography.json. The artist folder's `v` now includes
_discography.md so regenerating it re-syncs just that small JSON (isolated from
the albums' meta/cover). Manifest gains `disco: true` on such entries. Also
fixed the skip check to require all expected outputs to exist, so artist/
cover-only folders no longer rebuild every run. New `discographies` counter.
- sidecar: GET /discography?path=<artist rel> (ETag/304), documented in the
contract header.
- MUSIC_API.md: §2.4 + manifest disco flag + resync algorithm updated.

Standalone reference for the mobile team: auth, streaming (/stream +
X-Audio-Duration), the synced library index (manifest/meta/cover + per-album v
diffing, ETag/304), building/refreshing (reindex + SSE progress), the
recommended resync algorithm, and the data shapes (IndexMeta/Manifest/
IndexStatus/IndexReport).
