MUSICALITY: the second verifier — genres proven good, not just distinct

Paul: "You've got it with the diagonal. Look at the class of issues we're facing and make it possible to improve and balance genres for true musicality." docs/MUSICALITY.md is the design: today's taste complaints, formalized as per-genre laws with NAMED failures.

• engine/musicality.js ships the symbolic half: BLOOM (per-part time-to-first-onset against per-FORM bounds

• Reggae's kick-on-three promise measured FALSE at the state level — its kit pool has no one-drop (kick lands on 1); the transition fix was necessary but the card still lies.

• The worst-10 is SYSTEMIC, not individual: pop/drop form intros hold drums out ~2 sections (beat 62 vs bound 32) across ten genres

• chalkvespers asks its choir 20 semitones above its natural ceiling. Baseline: 19 OK / 209 WARN / 0 FAIL; no never-sounding parts; all three seed promises hold.
