The build passed and six tests ran; five green. Details in OPSTACK-PROGRESS.md.
1. DiffLayerContention's failure was the test, not the plugin.
GetTotalModificationCount() sums STORED ENTRIES, not operations -- a stroke is
filed under every chunk its AABB overlaps, so 400 radius-6 spheres straddling
chunk corners store 3200 entries. The assertion now compares the stored count
against the chunk fan-out ApplyModification itself returned, which also checks
that the re-mesh list handed to the caller describes what was actually written.
Everything the test exists for had already passed: 7 readers, 28.7M read
rounds against 760 writes and 6 Clear()s, no crash, monotonic version.
2. MazeEquivalence: 454/20000 samples differed by at most 1.907e-06 -- exactly
one ULP at magnitude 16 -- with ZERO crossing the isosurface, i.e. not one
triangle would move. Leading hypothesis: the original routes noise coords
through an FVector (double in UE5) and back to float, rounding twice, while
the op passed floats straight through; under /fp:fast those round differently.
The op now reproduces the detour on purpose, with a comment against
"simplifying" it. Unverified -- it predicts 0 differences next run. If drift
remains, next candidate is FMA contraction across translation units.
Also recorded, because it is the perf half of the whole refactor: the Maze op
stack proved 23 of 60 tiles uniform. ClassifyTile proves ZERO for any cave
archetype today.

CODEMAP gains 3.2c (VoxelDensityPrimitives), 3.2d (the operator stack and its
factories), FVoxelOpSample under 3.2b, and the two new tests under 3.12.

The "starting Phase 0.5" entry said the ClassifyTile test self-skips when the
fixture fails to build. It does not -- all four tests fail loudly with a message
identifying it as a fixture failure. Corrected by appending, since the log is
append-only.

Phase 0.5 and the Phase 1 skeleton marked WRITTEN / NOT COMPILED (not "done" --
the gates are not met until the tests actually run). Section 8 independent fixes
2, 5 and 6 ticked. Section 9 "Resume here" now says BUILD.

AUDIT P1: every markdown design doc except CODEMAP.md was untracked, so
ARCHITECTURE / AUDIT / OPSTACK-PLAN / fable-idea / REVIEW_FINDINGS lived
only on disk. Replaces the single !CODEMAP.md exception with !*.md.
Also makes OPSTACK-PROGRESS.md commits actually record something, which
the unattended crash-safety discipline depends on.
