The margin is exonerated. Every earlier run excluded 8 voxels at each strate boundary, and voxels 4-8 of those are ordinary interior, not seal -- the same window mistake that produced "FlatPlain is 99.95% void" at margin 32. So the query was re-run at margin 0, 2, 4 and 8. All four stay negative; margin 0 includes the seal itself and still reports negative. (The implementation had clamped explicit margins to >= 1, which made the margin-0 check impossible; Codex found and fixed that.) Diagnosis -- this is not a near-miss wall: arrival LowerPoint (65.8, 95.8, -1047.25) departure UpperPoint (88.4, -104.6, -991.58) XY separation 201.7 voxels (~50 m), Z delta 55.7 arrival component 22,531 cells (22.0% of air) departure component 21,621 cells (21.1% of air) nearest approach between the two components: 135-179 voxels Two large, healthy, entirely separate shaft networks half a strate apart. Nothing to breach; the archetype has no lateral connection at all. 16-seed sweep: 1 pass, 15 fail. Not one unlucky world -- structural. So: descend into a VerticalShafts strate and you probably cannot reach its exit. This is the "live hole in the shipping game" COMPOSER-NOTES Tier 1 predicted, now measured instead of assumed. Stated precisely, because it names the fix: VF_SuggestLandingPoint makes each mouth land in open space, but NOTHING makes the two mouths of one strate land in the SAME open space. New: VF_DiagnoseConnectivity returns component sizes and the spatial separation between the two mouths' components, so a near-miss and a never-meant-to-connect read differently instead of both being "false". No generation change, no threshold tuning. The fix is a design decision. Build clean, 19 succeeded / 0 warnings / 0 failed. Sweeps 3.4 s + 6.9 s.
