pub const ROOM_SURF_WARP_SUBDIVIDED_COUNT: u16 = 242;Expand description
Warp probe (read-only diagnostic, room-surface-profile only).
Room surfaces bucketed by the closed-form predicted affine texture
error from docs/texture-warping-2026-07-27.md, cross-tabbed against
what the depth-band subdivision rule actually decided. Buckets are
<1, 1..2, 2..4 and >=4 calibrated texels.
Error is reported as count / sum / max in 1/16 texel units rather than
as buckets: a first run bucketed it and put 99% of surfaces in the
top bin, which answers nothing. Sum and count give the mean; max gives
the worst case. ..._UNDER_1TX is the one bucket worth keeping, since
“subdivided a surface that could not warp” is wasted primitives.
