- Clipmap: finer rings snap to child-pair boundaries, so no two desired tiles of different
levels overlap. Owner config 635 overlapping pairs -> 0; LOD0 ring 343 -> 512 tiles.
New test sweeps 6,174 cases; fails on 7486c29 as intended, passes here.
- Shared room-graph cache: Entry->Cache read/written only under the mutex (race fix).
- ReconcileReadyTransitionVisibility indexed: moving p95 32.0 ms -> 0.31 ms.
- Block-vs-scalar density equivalence test: 5.1M samples bit-identical; catches an injected
optimistic EffectOverBox (5,612 mismatches).
UNVALIDATED for merge: collision-gate stress passed 1 of 4 runs on this code (fails at 4.56 m,
support collision unready at start); it passed on 7486c29. No control run yet.
