Settings → Calls A/B denoise tester leaked audio resources:
- play() built a denoise model node (DeepFilterNet/DTLN worker/WASM) + optional
gate but stopPlayback only closed the AudioContext, never disposing them —
each A/B playback-through-a-model leaked a worker. stopPlayback now mirrors
stopLive (gate.disconnect → model.dispose → node.disconnect).
- A generation token (playGenRef, bumped by stopPlayback) makes play() discard
what it built if superseded during the async WASM/worklet load — closing the
same leak in the rapid-Play-click race, the Stop-during-load case, and the
unmount-during-load case, and stopping a superseded rejection from tearing
down the winning playback.
- A mountedRef guards the getUserMedia paths (startLive/startRecord) so closing
Settings during the mic permission prompt doesn't create untracked
resources / setState-after-unmount; its effect sets true on mount (not only
false on cleanup) so it survives a StrictMode/Activity same-fiber remount.
Bug-hunt findings from LOTUS_TODO. Three review passes: the first two confirmed
the base fixes and surfaced the concurrent-load leak + StrictMode fragility; a
third traced all six play() interleavings of the generation token. Gate-green
(tsc, eslint, prettier, 914 tests, build).
