Edge-to-edge textures have no composition to vary. Two songs of Voronoi Shatter
measured 0.004 apart in the layout block, and that was honest rather than a
metric failure — the cells changed and the arrangement did not, because there
was no arrangement.
So the identity now decides a FOCUS: one to three points, a reach, and a pull
that either draws the field in and densifies it or opens a void. The points come
off the same lattice everything else is placed on, so a scene using them is
composing in the song's terms rather than inventing a centre of its own.
focusField and focusWarp are in the contract, available to any field scene that
wants somewhere to be about.
Voronoi Shatter is the pilot. It tiles in the warped coordinate, so cells crowd
toward the focus or pull away from it, and its seams tighten where the field
gathers so the effect reads as a change in the shatter rather than a brightness
blob laid over one. 0.0463 to 0.0588, comfortably clear of the bar.
It did NOT work the way the hypothesis said. The gain is in orientation, 0.140
to 0.194, and in texture; the layout block moved from 0.004 to 0.007, which is
still nothing. Warping where the cells sit changes what they look like without
changing where the energy is, because the field still covers the frame corner to
corner. Layout stays blind to this family until a field is allowed to actually
fall away from its focus and stop being full-frame — which is a bigger change to
what these scenes are, and worth deciding rather than sliding into.
