@@ -57,9 +57,9 @@ and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0
 - **Audio-monitoring control plane** — makes `audio-monitoring` the shared live-monitoring coordinator. Core now exposes provider registration/list/selection, explicit user-action `start`, requester-counted `stop`, prompt-free `inspect`/`monitoring.status`, and `set-direct-monitor` through the capability runtime. Monitoring starts integrate with selected `audio-input` readiness, background requesters can only attach to active compatible sessions, active sessions survive song/playback stops without auto-resuming after reload, native providers suppress compatibility-backed legacy monitor paths, and diagnostics/Capability Inspector now show providers, sessions, requesters, direct-monitor state, bridge hits, and distinct safe outcomes (`provider-selection-required`, `user-action-required`, `incompatible`, `unavailable`, `stopped`, etc.) without exposing raw audio/device data.
 - **Playback control plane** — promotes `playback` to an active core capability domain for song transport, timing, loop, route, requester/observer, bridge, and diagnostics state. Core now exposes `inspect`, user-authorized `start`, `pause`, `resume`, `stop`, `seek`, `set-loop`, and `clear-loop` through the capability runtime while `static/app.js` keeps raw `<audio>`/JUCE handles private behind a redaction-safe adapter. Playback diagnostics use pseudonymous targets in exported bundles, local display labels only in the Capability Inspector, bounded recent outcomes/events, and bridge accounting for `window.playSong`, legacy `song:*` events, `window.slopsmith` transport helpers, loop helpers, and browser/native route handoff.
 - **3D highway — Tone HUD, fret dividers, chord-diagram toggle, FPS counter.** The bundled `plugins/highway_3d` gains an amber **Tone-change HUD** (shows the active tone and the next scheduled tone change; position / size / visibility configurable in settings), a **fret-dividers** toggle (vertical dividers on the highway, on by default, via `h3dBgSetFretDividersVisible`), a **chord-diagram visibility** toggle (`h3dBgSetChordDiagramVisible`), and an **FPS counter** setting migrated to `BG_DEFAULTS.fpsVisible` (drops the legacy `h3d_showFps` localStorage key). Chord-diagram position is restricted to `tl`/`tr`; legacy `bl`/`br` values are coerced on load. Perf: accent-halo shell descriptors are pre-built per string in `initScene()` and the chord-verdict cache key is encoded as a number, eliminating per-frame allocations in the `drawNote()` and chord hot paths.
-- **Sloppak assembly preserves a short preview clip.** When a source chart carries a separate short browser-preview audio clip alongside the full song, the sloppak assembler now decodes it to `preview.ogg` at the sloppak root and records it under a new top-level `preview:` manifest key (POSIX relpath, same shape as `lyrics`/`cover`). A failed preview decode is logged at debug and skipped without aborting the overall build. Sources with no separate preview are unaffected. Older sloppak readers ignore the unknown `preview` key, so the change is purely additive (sloppak-spec.md §5.5 backward-compat). Documented in `docs/sloppak-spec.md` §2 alongside the other optional top-level keys. Enables [`slopsmith-plugin-song-preview`](https://github.com/byrongamatos/slopsmith-plugin-song-preview) to render hover-to-listen previews for sloppaks without seeking into the full audio.

 - **Generic plugin asset route** — `GET /api/plugins/{plugin_id}/assets/{path}` serves arbitrary static files a plugin bundles under its own `assets/` directory (AudioWorklet modules, WASM, images, etc.), so plugins can self-host browser-fetchable assets without a CDN (Principle II). Containment is enforced by `lib/safepath.safe_join` against `<plugin>/assets/`, so `..` traversal, absolute paths, and NUL bytes cannot escape `assets/` to reach a plugin's Python modules. `.js` is served as `application/javascript`. First consumer: the stems plugin's pitch-preserving time-stretch worklet.
-- **Minigames framework — bundled as a core plugin (`plugins/minigames/`).** Promotes the upstream [`slopsmith-plugin-minigames`](https://github.com/byrongamatos/slopsmith-plugin-minigames) repo into the core bundle so every Slopsmith install gets the framework out of the box (same promotion path used for `highway_3d`). The plugin adds a top-level **Minigames** nav link (alongside Library / Favorites / Upload — not buried in the Plugins dropdown), a library-style card grid of installed minigame plugins, and a shared profile layer (XP, level, per-game leaderboards, cross-minigame unlocks) persisted under `CONFIG_DIR/minigames/` and opted into the settings export. Other plugins that want to ship a minigame add a `minigame` block to their `plugin.json` and call `window.slopsmithMinigames.register(spec)`; the SDK exposes scoring (`createContinuous` runs a self-contained YIN tracker; `createDiscrete` / `createChord` wrap `note_detect`'s `createNoteDetector`), HUD primitives, run persistence, and a scheduler so individual minigames don't need their own DSP or backend. Backend endpoints live under `/api/plugins/minigames/{runs,profile,registry}`. The framework is plugin-shaped (not core code) per Principle III, but bundled so it ships with every install. First consumer: [`slopsmith-plugin-flappy-bend`](https://github.com/byrongamatos/slopsmith-plugin-flappy-bend), shipped separately.

 - **Alpha-build heads-up banner** — when `/api/version` reports a version string containing "alpha" (case-insensitive), an amber banner appears at the top of the library section warning users that the build is in active development and may have bugs or breaking changes. The banner stays hidden on stable / beta / RC builds. No persistence or dismiss state — it's a passive notice, not a modal.
 - **Drum vocabulary expanded to 18 pieces** — adds `stack` (MIDI 30, from GM's extended-percussion range, unused by real drum-kit MIDIs) and `bell` (MIDI 80 "Mute Triangle", also unused in real drum-kit MIDIs) to `lib/drums.py` PIECES. Inserted in the iteration order so the editor / highway lane ordering is *hi-hat → stack → crash → … → ride bell → bell*. Both are cymbals; default shape `circle_jagged` (stack) / `circle_dot` (bell). Old drum tabs round-trip unchanged — the schema is permissive and existing piece-ids are untouched.
 - **GP / MIDI drum import surfaces unmapped notes** — `convert_drum_track_to_drumtab` (`lib/gp2rs.py`) and `convert_drum_track_from_midi` (`lib/midi_import.py`) gain an optional keyword-only `out_unmapped` parameter. Callers that pass an empty dict receive a per-MIDI record of every silently-skipped percussion note (`{midi: {"count": int, "times": [float, ...]}}`, times capped at 100 samples per note). This lets the editor plugin show a warning + manual-mapping UI on import instead of silently dropping unmapped notes. Default behavior unchanged for callers that don't opt in.
