Fusion DJ Deck
Crossfade between two Pfaffian cost classes. Pick a voice for deck A and a voice for deck B, hit start, and slide the crossfader between them. Distance in cost-class space is audible: same class sounds the same, distant classes sound very different.
Each voice's pitch, timbre, and chord voicing come from the Lane 5 Pfaffian → audio mapping. The crossfader is the cheap and honest version of "interpolating between cost classes" — continuous in volume, discrete in structure.
amp · cos(ω · t)The universal canonical-oscillator class. After proper N=5000 null control: 29/403 bio (7.2%) vs 135/5000 random (2.7%) = 2.7x enrichment, q < 0.0001 after BH-FDR. 18 distinct domains. Real, statistically significant, modest — not the 'binary 0/50' the smaller controls suggested.
Residual after FFN (full block)What a full Transformer block decomposes to in cost-class space. Above any biological corpus reaches.
