Every track: tuple-unpacked scale degrees, small local helpers (rest_bars, chord_bars, play_phrase), data-driven drum patterns and phrase tuples, sparse-event dicts, explicit velocity lists for fades, dead code removed. Net -1,415 lines across 25 files. Adds .fingerprint.py, a verification harness that hashes every audible parameter of a score (notes, voicings, velocities, bends, drum hits, LFO automation, part settings). All 25 tracks fingerprint identical to their pre-refactor baselines, stored in .fingerprints/. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
