The deepest audio lever: a score carries no recording, only note events.
A deterministic trig-free reference synth (phase-accumulator oscillator +
linear ADSR, all in the Fx floor) reconstructs a canonical i16 PCM
mixdown; conformance is mixdown-equivalence, the music counterpart of
spatial audio. A soundfont/neural instrument is the sink's presentation.
- wai-rs `score` feature: WSCR container + reference synth + mixdown/
score hashes; corpus (scale/chord/arp) via wai_score_vectors; registered
+ tiered Lossless.
- wai-web ScoreSink + the /score browser sink (in-tab verify + Web Audio).
- extensions/score.md, SPEC §5 row, content-taxonomy music → ✅.
Green: wai-rs all features (68 lib + integration) + clippy, wai-web wasm.
