pub const SKELETON_FLOOR: f32 = 0.05;Expand description
Floor on the fixed-point set’s diameter (ADR-0088).
Required rather than defensive. Two drawn maps’ fixed points genuinely
approach each other as a morph interpolates between two tables, and a
diameter of zero makes skeleton_scale’s reciprocal diverge — every
particle’s stored distance would come back inf or NaN and the whole
figure would sample one end of the palette.
It is a constant somebody picked, in the same position ADR-0075’s 0.97
and ADR-0087’s 180 occupy, but it is bounded by measurement rather than by
taste: the_skeleton_never_collapses_across_the_morph sweeps every ordered
figure pair, every position of the 33-point morph sweep and all three lever
settings, and asserts the observed minimum diameter sits above this while
printing the margin and where it occurred. A thin margin there does not mean
“tune the floor” — it means the channel degenerates somewhere in the morph
and the figure pair the assertion names is where to look.
