A new top-level section building the metabolism concept: the track
supplies the food field, event impulses and per-section laws; the seed
picks the species (a rule set, not a parameter vector). Same song + seed
=> bit-identical frames; different songs => different worlds.
- analysis: single FFT pass -> per-frame feature table; score (onsets
folded into world geometry via voice ring + pitch-class sector), wells
(food placed by the harmony), graph (band correlations -> interaction
matrix), laws (per-section regimes)
- sim: typed-array world, 3 castes (builder/orbit, forager/commute,
spark/orbit-wide) with causality rings, persistence trails,
consequence field; fully deterministic
- lens: software framebuffer renderer (PNG in node, ImageData in
browser) + event-reactive camera (cuts on activity change, alternating
shot sizes, drift-and-push)
- metrics: coupling x residual fitness (not per-frame descriptors) plus
a grown-structure fingerprint; report + strip tools; 15 tests green
- DESIGN.md captures the concept, invariants and build order
3 reference test signals (drone/runner/dusk) grow measurably distinct
worlds while seeds of one song stay in the same biome.
