// Music — the library, the player, and the phone and tablet apps that stream from it.
//
// The second plugin extracted from the platform, on 2026-08-15. Bigger than offscale and, unlike it, not
// a clean cut. It took two passes: the first left three pieces in the platform, and the second moved two
// of them here after the owner read the code and asked why the platform still had files named for music.
// He was right — one of the three "seams" turned out to be dead code holding the door open.
//
//   api/router.ts     the sidecar proxy, built here — thin, and it must never grow music knowledge
//   cliamp/           the second playback path, parked
//   widgets/          the dashboard widget, parked
//   assets/icon.png   the dock tile, published to /plugins/music/ on install
//   sidecar/          the whole /api/music contract: indexing, streaming, per-user state
//   db/               music_favorites, _playlists, _playlist_items, _now_playing
//   web/              the library panels; the shell renders the Workspace
//
// ── What stayed in the platform, and why ── (nothing. All three moved here.)
//
// 1. ~~cliamp~~ — MOVED HERE, all of it, into `./cliamp/`. The sidecar halves, the relay, the file
//    browser's panel and its `Play` action. `src/servers/sidecar/music/`, `src/servers/api/cliamp/` and
//    `src/servers/api/music/` no longer exist, and `server.tsx` has no cliamp anything. It is PARKED, not
//    working: bringing it back needs a plugin to own a websocket, which is a platform gap.
//
// 2. ~~The dashboard widget~~ — MOVED HERE, to `./widgets/`, and unregistered from WidgetRegistry.
//    Parked: plugins cannot contribute widgets and that mechanism is not built.
//
// 3. ~~The global player overlay~~ — MOVED HERE, to `./web/`. It stayed while the widget pinned
//    `useMusicPlayer` in `officerdev`; once the widget left, the only platform dependency was one line
//    in DashboardLayout. `MusicPlayerHost` now mounts inside the MusicDetail panel, where it owns the
//    audio engine and renders nothing — which is what it already did on /music.
//
//    `[phase 2]` Leaving /music stops playback. Giving audio a life outside the route needs a shell slot
//    a plugin can contribute to, or the engine hoisted to module scope. Deferred deliberately; nothing
//    breaks meanwhile.
//
// ── Host dependencies ──
//
// Music is the plugin that made `osDependencies` exist. Offscale was self-sufficient, so until this one
// there was nothing to declare and no reason to build the field — see ./PLUGIN.md.

  // The key is `music` and that is not incidental: it is the key the platform's own registry used until
  // this extraction, so every existing `role_capabilities` grant keeps meaning what it meant, and the
  // overlay's `can('music')` keeps resolving. Renaming it would have been a silent data change.
  //
  // `[open]` What a member's grant MEANS here is this plugin's own job and is not finished. Favourites,
  // playlists and now-playing are already per-caller — the sidecar scopes every one of them by the
  // `X-Officer-User` header the proxy injects — while the library itself is one shared index for the
  // household. So "whose row is this" already has a real, non-uniform answer, which is why the platform's
  // side of it is a uniform read/write and nothing more. Designing the rest belongs in these queries.

      // them safe at read level. The manifest deliberately has no `personal` field, and adding one would
      // be designing the per-user visibility model that is explicitly not this extraction's work. It
      // costs nothing to go without: `isRequestAllowedAtLevel` concatenates `personal` and
      // `readOnlyWrites` into a single allow-list, so the two are the same mechanism under two names and
      // a read grant permits exactly the same four paths it permitted yesterday.

  // Both come from one package everywhere, which is luck rather than a rule — hence a name per manager
  // rather than one canonical name. `packages.sh` records why that indirection was rejected.
  //
  // They are declared SEPARATELY even so, because the platform probes binaries and these two fail
  // differently. Losing `ffprobe` is the quiet one: the indexer catches the spawn error and returns a
  // track carrying its filename and nothing else — no title, artist, album, duration or embedded
  // lyrics — then reports success. Losing `ffmpeg` costs cover art and video poster frames, which is at
  // least visible. Naming both means the owner is told which of the two they are missing.
