- Wall relief noise is skipped when its hard-bounded contribution cannot change the final max; mouth surface/tread noise only on paths that use it. - Exact active BVH-node masks cached per tile/passage/segment range; no per-sample lower_bound. - Full-view audit imports the exported Core plan (not the stale 26-point root route): 21,425/21,425 walkability samples pass. Cold (L80 protocol, medians) LOD0-2: SW 1.16->1.11, FI 2.86->2.51, TN 2.88->2.54, VS 1.23->1.22 s. Passage share FI 64.6->58.7%, TN 65.4->58.4%. Hashes identical (v214). TN "slowdown" from L81 not reproduced (5 pairs, 3.08 -> 2.75 s). Fast tier PASS; Linux UE host builds.
