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.
