vadimwit	4727645bb9	fix(piano): dedupe duplicate absolute notes in pianoVoicing (task L-13) ... A forced rootless sus2 collided the suspended-2nd and synthesized 9th onto one key (notes [26,26,31]). Dedupe at the single funnel point ([...new Set(placed)]); pcs/bass derived from the deduped array. No-op on default/chain path (L-11 render unaffected). Critic: Set merges only identical absolute integers (same key) so no needed note is lost. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>	2026-06-16 11:00:43 +01:00
vadimwit	e2a1552843	feat(piano): pure piano voicing resolver src/lib/piano.js (task L-10) ... pianoVoicing({rootPc,quality},opts?) -> {notes,pcs,bass,style,label}: shells (1-3-7), rootless A/B (3-5-7-9 / 7-9-3-5), root-position; opts.prev / pianoVoicingChain thread a loop with octave voice-leading optimization. Helpers: hasTrueSeventh, voicingToneSet. Pure, imports only theory.js. Critic PASS: 56 voicings (14 qualities x 4 styles), 0 wrong notes, deterministic. New unimported module (no frontend impact yet) — D-10 renders it, L-11 wires the piano tab. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>	2026-06-15 19:05:44 +01:00
