Fr0zkaandClaude Opus 5 0208e93606 measure(perf): re-rank component costs on the current build -- the tunnel core is now the largest
Measurement only (Codex): the same remove-one ablation method and command line as 6ccf371, all 14
voxel.TunnelAblate* bits static x2 and the top five moving x2, on the committed tip after the
landing-post, cave-warp, gap-floor and option B changes.

Static leaders now: tunnel core 20.84%, tunnel SDF 12.64%, passage carving 9.08%, cave warp 6.68%;
27.62% remains unattributed/shared. The tunnel core could not be measured at 6ccf371 because of the
ablation gate bug fixed in 7a972f5. The two tunnel evaluations together are now about a third of
worker time. Next targets as proposed: tunnel SDF/core merge (field-changing), passage carving
reuse (exact), cave warp result reuse (exact). Full tables and the launch ledger are in
PERF-SAMPLED.md.
