The Bachian layer now travels: each Fibonacci chapter walks its OWN functional progression (calm tonic → ii–V–I → richer turns → modal Eb in the strange REM → plagal homecoming) instead of one loop transposed. The arpeggio figuration is drawn from an 8-pattern library walked bar to bar, with its range widening (5→7 tones) into the dream — so it keeps reshaping instead of repeating. Spectrum + per-minute loudness re-verified (arch holds, texture now travels). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
