The window excluded a whole chunk (32 voxels) at each end to avoid a 4-voxel seal band -- 8x too much. On 4-chunk strates that discarded half of every strate, floor included, so the pass was measuring the open air above the ground and calling it the strate. The margin now derives from the seal that actually exists: ceil(2 x BoundarySealThickness), clamped to [1, height/4], overridable via InteriorMarginVoxels. The fixture resolves to 8 voxels. FlatPlain/CrystalChamber walkable fraction: 0.00044 -> 0.0578, ~132x. The "99.95% empty void" reading was the window, not the world. Metrics now carry ResolvedMarginVoxels, SampledMinZ and SampledMaxZ, and the test prints them. A measurement that does not state the volume it measured is exactly how the previous defect survived review. VerticalShafts largest-component share rose only 0.074 -> 0.119 across 57 components: the window explained part of the swiss-cheese signal, not all of it. That one is at least partly real. Coarse-lie guard still load-bearing: 24 routes checked, 3 refuted at full resolution (was 21 / 2). Build clean, 18 succeeded / 0 warnings / 0 failed, confirmed in Saved/Logs/VoxelM.log rather than from the agent's summary.
