Two compounding mistakes in 1.37.0's derivation, reported as a hole much larger
than the head with the new head generated floating inside it:
- the upward slack was scaled by the mask's HEIGHT (hh * delta / tilt). Height
swings with how much neck the mask took, and a portrait-shaped identity image
(tilt < 1) multiplied it further: a 300x400 head with a 0.6 reference asked
for 136 px above. Every slack is now a fraction of the head's WIDTH, the
stable dimension, capped at 25% sideways and 30% up.
- latent_mask_dilate was derived from mask_grow and forced to at least one
cell, which added a whole 32 px on EVERY side -- including down, which the
pixel grow deliberately holds at the base -- on top of a grow that already
carried the slack. It is 0 now: _mask_to_latent reduces with MAX, so any cell
the mask touches is fully editable already. The same head asked for 4 cells,
128 px, before this.
Also undo the guider injections in reverse: with several chunks each injection
captured the state the previous one left, so undoing forwards restored chunk
1's specs onto the guider instead of clearing them.
Tests pin both: growth stays under 45% of the head's width across every
reference aspect and headroom, the latent dilation stays 0, and the crop box
always holds the grow plus the feather.
