Correctness round on AUDIT-COLD-2026-09-14.md (Codex; key fixes reviewed by me). #7 (determinism, introduced by the tile-cache work): the refetch guard in GetDensityAt now rebuilds on `bTileCacheContext != CP_UsesTileCacheWindow` or when the worker-local stack/core were moved into a cache entry (`CP_ActiveTunnelDensityCache != nullptr`). A cache miss can no longer evaluate a moved-from, empty operator stack. Test (VoxelForgeCorrectnessRoundTest): the pre-fix binary CRASHED in the context-switch case (negative control); the fixed binary passes with 0/5 coarse and fine mismatches, and warm vs fresh origin-tile meshes are identical. Also fixed, each with a focused test that passes: - #3/#8: worker diff/surface/biome caches carry owner/layer identity (no cross-world reuse); #9: the shaft key gains LedgeSpacing/LedgeDepth and the island key BoundarySealThickness; #14: clearing passages bumps PassagesVersion; #21: HasAnyModInChunkRange is proportional to the queried range (the sealed-rock proof calls it per candidate). - #1: the density-volume fill thread is paused/drained with generation; #2: each content manager joins its own decoration tasks before destruction; #15: non-finite/invalid modification geometry is rejected; #20: zero-width transition blend is guarded at runtime. - Also #4-#6, #10-#13, #16-#18, #22. #19 is valid C++20 and unchanged. Verified: canonical export b3e5f4c3..9b377; capability 20,830 / 10,909; fresh trace 841/841 identical, 0 origin-column mismatches; static mesher calls 18,078,130. Performance: two pairs disagree in sign, and the means are final -2.5% static / -0.8% moving; no repeatable regression. Known and NOT caused by this round: ClassifyTileSoundness and PassageLandsInOpenSpace were already failing (15/17 in the grouped suite). Queued for investigation. Ledger: first determinism launch hit the DDC fatal (crash folder 57DB6ADC, 23:21); the retry exited 1 on the two known failures; one malformed multi-test launch was inconclusive; one malformed trace launch was stopped; one launch with an unquoted project path found no test and its retry passed. Everything else passed. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01TaFdXhTdYMkW1xrV6ApT6Y
