Fr0zkaandClaude Opus 5.5 41a9265ebd measure(step2a): candidate bins alone are slower -- the per-sample GetDensityAt call must go ...

Editor-only ablation (explore commandlet, -regioneval, default off): 8^3 bins for rooms,
room-floor joins and tunnel chains, but every point still goes through GetDensityAt.
259^3 ring, seed 1337, six workers:
  live  : 6.776 s wall, 29.16 s worker CPU, 1.679 us/sample, 21.2 candidate visits/sample
  binned: 19.54 s wall, 50.02 s worker CPU, 2.879 us/sample, 16.4 candidate visits/sample
Correctness: zero Q16 (x16, ties away from zero) disagreements on the full ring and ~284k probes
on 4 more seeds (composer recipes, warped rooms, passages, landings, strate edges, edits);
shrinking room reach to 0.5 -> 18,107 Q16 / 735 sign differences (the check bites).
Not the planned region program: the step-2 question is still open. Baseline for the next attempt:
1.68 us CPU per sample on the live path.
