Round-1 Lane E audio + the two remaining UI surfaces, consolidated from the JING5
clone onto main and made determinism-clean:
- audio/synth.js — procedural voice bank (primary path; audible with an empty manifest)
- audio/engine.js — WebAudio graph, cue router, bed, heartbeat; now the listener for the
11 gameplay bus events that were previously firing into the void
- ui/feedback.js — feed-corruption damage overlay (an ART_BIBLE law previously unmet)
- ui/cards.js — title / medal / pause cards; boot now honours ui:pause
- boot.js — mounts all five modules with per-module failure isolation and a
frame() tick (never step(), so stepped sims stay deterministic)
Determinism gate: threaded engine's seeded rnd (mulberry32 off ?seed=) into createSynth,
replacing every Math.random in synth.js. Audio texture is now reproducible per-seed and
qa.sh is green.
Verified: QA green; runtime smoke on ?seed=7 scheduled 182 osc + 91 buffer voices + 268
envelope ramps during play, zero console errors.
