Audio-truth audit: per-voice expected-vs-actual, painted red + downloadable

"Track when a node is expected to produce sound and doesn't" (Paul) — the renderer now measures each voice's ACTUAL contribution RMS per bar as it bakes (sampler + faust units, additive meters, mix bytes untouched

• Hunting the "random mutes": the strip-fuzz gate found a real NaN landmine — the per-note chorus delay read could wrap negative (undefined → NaN poisoning the whole bar's dry bus, silencing every voice).

Verified: strip-fuzz, audit-gate (new), segment-parity byte-equal, resilience, wavout, live, genre-viz, explorer-ui, engine, matrix 93/93.
