Deep pass: live song structure, glitch fix, sonic fingerprints, EVALUATION

Glitch/static fix: live engine recompiled instruments EVERY bar (glided numerics changed the signature) — now recompiles only on model swaps or an 8-bar numeric refresh; lookahead 2.2s -> 4.5s.

• Song structure LIVE: exploreLive walks the form's real sections (cycles, fills on final cycle, sweeps on entry/exit) instead of looping one groove

• Sonic fingerprints: brass + strings models (pad/lead), master grit drive (per-genre + live channel + slider), generative "melodic" bass (walks chord tones with approach notes, never repeats a bar), bass…

• Samples: 78rpm shellac via George Blood collection (Armstrong horns, After You've Gone) wired into blues/jazz/triphop hits; recipe url-encodes and is fault-tolerant.

• EVALUATION.md: honest model assessment vs the actual purpose + roadmap (scale-aware melodies, perc lanes, fill intelligence, form-quantized journeys, audio-verifier in the generation loop).
