Lane F R11: wire interior audio beds + audio smokes + gate scope
Interior audio (interior_mode): enter -> PROCITY.audio.playInterior(room.audio) with Lane C's
{musicKey,toneKey} (fade in), exit -> stopInterior() (0.7s fade). Guarded/no-op when
muted/noassets/pre-gesture -- silent-and-happy.
New smoke_audio gate (flags harness, fresh Chromium per the R10 standing law): pre-gesture silence
(ctx not unlocked), 0 boot errors, ?mute=1 muted, ?noassets=1 zero audio fetches, enter/exit
AudioNode leak-free (12 cycles, 8 shops with a music bed, live sources bounded at 5). Gesture via
keyboard -- a mouse-click gesture tripped PointerLockControls in headless.
scaffold_check: scoped the Math.random generation-ban to exempt runtime FX PLAYBACK
(web/js/world/audio.js) -- Lane B's footstep SFX variant/gain jitter is transient, not world
generation (which shop plays which bed is seeded upstream in interiors.js). Noted to B.
Soak with audio on PASS (heap 48MB stable, 0 errors, no drift). qa.sh --strict GREEN 6/6.

## Round 11 (the audio round) — DONE ✅ (v2.1)
|
||||
|
||||
John greenlit "generate freely". E generated the pack (23 assets, `web/assets/audio/`, 8.7 MB ≤ 25),
|
||||
B built the WebAudio engine (`audio.js`, self-unlocking, self-ticking), C added `room.audio =
|
||||
{musicKey,toneKey}` to buildInterior. **Lane F wired + verified + tagged v2.1:**
|
||||
|
||||
| task | result |
|
||||
|---|---|
|
||||
| **F1 — interior beds** | ✅ `interior_mode` enter → `PROCITY.audio.playInterior(current.audio)` (fade in), exit → `stopInterior()` (0.7 s fade). Guarded/no-op when muted/noassets/pre-gesture. 2 lines, the seam B/C designed for. |
|
||||
| **F2 — audio smokes** | ✅ new `smoke_audio` in the flags harness (fresh Chromium): **pre-gesture silence** (ctx not unlocked), **0 boot errors**, **?mute=1** muted, **?noassets=1 zero audio fetches**, **enter/exit leak-free** (12 cycles, 8 shops with a music bed, live AudioNodes bounded at 5, made 42). Caught + fixed my own gesture-via-mouse-click tripping PointerLockControls in headless → gesture via keyboard. |
|
||||
| **F3 — soak + tag** | ✅ soak with audio on **PASS** (heap 48 MB stable, 0 errors, no drift). `qa.sh --strict` **GREEN 6/6**. **v2.1 tagged + pushed.** |
|
||||
|
||||
**Cross-lane (F's own gate, noted to B):** B's `audio.js:143,145` use `Math.random()` for footstep SFX
|
||||
variant + gain jitter — legitimate transient runtime FX (which shop plays which bed is seeded upstream
|
||||
in `interiors.js`), but it tripped F's generation-determinism `Math.random` ban. F **scoped the ban
|
||||
correctly**: `web/js/world/audio.js` is runtime *playback*, not generation → exempted in
|
||||
`scaffold_check.mjs` (B may instead add a `// cosmetic` marker; either is fine).
