- The magpie's white, restated exactly. The wing-bar occlusion claim is the strong one and it now
carries its footprint proof: the bar's (x 0.174-0.316, z 0.005-0.055) lies ENTIRELY inside the
wing's (x 0-0.34, z -0.085-0.065) with the bar 3 mm above it, so from below the wing hides it.
The nape box tops out at 0.067 against a head surface at 0.0728 (I had written 0.065, and had
the sliver on the wrong side). And the flank argument is now the honest one: nape and rump are
14 mm and 20 mm slabs on a 166 mm bird = 1.3 px and 2 px of white at 64 px.
- THE CLASSIC ARGUMENT FOR THE ARCADE IS INVERTED relative to R38 and I nearly carried the wrong
one over. R38's ground palette is classic-safe BY ABSENCE (character.js returns frozen literals
for a null town key; classic has none). The arcade district exists ONLY on the synthetic, and the
synthetic IS the classic boot — so the kit lands squarely on the covenanted town and needs an
EXPLICIT flag test, ground.js's VERGE shape, not the by-absence one.
- arcade_measure.mjs now also counts chunks: arcade lots span exactly 2 (0,0 and 0,1) on all five
seeds, so a per-chunk arcade class is +1 draw in 2 chunks and +0 in the other 23.
