Some checks failed
check / check (push) Has been cancelled
- genome(seed, salts) now has three parts with their own RNG streams: shared (steps, form, swing, arc, layback, fill odds, phase offset), kit (density, frame, accent cycle, free snare) and keys (scale/root, progression, motif, hocket, bass tone, note lengths, range). ROLL KEYS now renews the harmony too; ROLL KIT leaves the keys alone. - Keys generators share one signature and can fix note lengths: MOTIF (the old line), 303 (acid bass, answers in the rests, drone or silent pad), TURING (8/16-bit shift register, DRIFT flips bits, 16-bar window), ARP (triad/7th arpeggio, roots on kicks). - Pages: KIT GEN, KEYS GEN; ROLL shows KIT / KEYS; slots keep both gens. - Flash record v3 (old settings ignored). Bring-up golden checksums updated. - C port matches; host test and ASan/UBSan pass. Intended music change: every seed sounds different (genome split, new generators). Vectors regenerated with npm run vectors; the case grid now crosses all kit and keys generators, with TURING runs past its window. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
