Classic Wave, Silk Ribbon, Kaleido Tunnel and Slow Orb all declared the `style` trait and honoured it with `col += sigGrain(uv)` and nothing else. A declared trait is a contract — the disqualification rule in Personality.js is the only thing keeping off-design scenes out of a track — so honouring it with dirt meant these four could not take the `texture: 0` opt-out the grain work introduced. Phase 9 measured their style response at exactly 0. They sat at texture: 0.35 as a stopgap, which kept speckle on the library's cleanest scenes purely to keep a gate green. Each already had the knob; it just was not wired to the track: - Classic Wave contrasts its wave through a bare smoothstep(0.2, 0.8). The transition width now comes from u_sigSoft and u_sigLine, centred on 0.5 so changing the hand does not change the exposure. Crest concentration is driven separately by u_sigLine, because a track is free to sample the scene's own u_softness at zero and the art direction must still show. - Silk Ribbon's strand width is u_sigLine and its falloff exponent u_sigSoft: a sharp track gets a filament with a defined edge, a soft one a haze. - Kaleido Tunnel drew its grid against a bare 0.42 — a line weight with no name. It is now a weight and a feather, both from the track. - Slow Orb's body edge multiplies the scene's softness by the video's, and gains a sigEdge rim so a sharp-handed track gets a defined limb. All four are now texture: 0. Style response measured against a maximally soft-handed versus maximally sharp-handed personality: Classic Wave 111, Silk Ribbon 216, Kaleido Tunnel 206, Slow Orb 102, out of 255 — previously 0. 104/104 checks pass including the slow set.
