Two targets, both hit, and the second is the biggest in-game win since the interval work. 1. THE FLOOR IS NO LONGER PATCHED IN The audit proved the backstop was doing the work: TunnelAuthoredFloorProtectionClamps fired on EVERY authored floor sample while the named fallbacks fired zero. The cause, in its own words, was that the stack composed the floor before the common disturbance/passage writers, so every sample looked like a post-hoc clamp. The floor is now composed ONCE, after those writers, at the final MC boundary. The clamp inside the operator stack is deleted; the metadata stays on the sample for the hand-off and for diagnostics but may no longer modify density. clamp fires 29,634 / 29,634 -> 0 player-fit cells 20,804 (unchanged) walk reachable 10,884 (unchanged) connectivity arrival -> departure, Connected geometry SHA-256 b3e5f4c3..9b377 IDENTICAL to8e42d6dexport, my 3 runs 1.320 / 1.424 / 1.439 s (8e42d6d: 1.357 / 1.365 / 1.420) ⭐ Byte-identical output with the patch removed entirely. That is the proof the clamp was never adding anything -- it was compensating for its own position in the pipeline. Three days of "is the floor native yet" answered by moving where it is composed. Remaining, and deliberately: the final support backstop still fires (6,509 export / 9,700 walk). Removing it is not capability-safe and it was not removed. 2. THE 551 ms EMPTY TILE IS GONE An EMPTY LOD0 tile cost 551.7 ms: it returned verdict=Mixed, ran the full mesher, and produced no triangles. Pure waste -- work done to discover there was nothing to do. The cause is precise and worth recording: `AnyPassageModifierNearLattice` fed `FPassageCarveOp::EffectOverBox` with a SPATIAL candidate test. Returning true killed the AllSolid hypothesis even when every exact MC sample had a zero carve factor. A "maybe something is near here" answer was being used where "does it actually change anything at these samples" was required. It now takes the cheap domain test as a reject, then consults the exact cached lattice carve factor the fold already computes. Unknown or non-finite geometry stays conservative. empty Mixed fallbacks 86 -> 0 no empty tile enters the mesher at all empty tile p50 48.7 ms -> 7.14 ms empty tile p95 451.3 ms -> 11.54 ms empty tile max 551.7 ms -> 27.86 ms ⚠️ Not fully at the "few ms" target: the remaining 27.86 ms tail is conservative tunnel-tail proof work, not the old fallback. Honest, and a different problem. Build 0 errors, three source files, no RMC or external paths touched. The shared walkable-volume descriptor was not started.
