A route-only floor profile cannot reproduce current support semantics: support is gated per sample by native density < 0, player-capsule clearance, later-bore deferral and neighbouring- passage capsule checks (the overlapping-coil tile exercises all of them). The exact per-tile boundary-band XY column cache matched all 24 hashes but showed no consistent readiness gain, so it is kept as a patch only (patches/band-column-cache-not-merged.patch), not merged.

Decision
Floor/support ribbon: stopped at the falsifier. A route-only floor profile cannot replace the current support decisions. Support is gated by pointwise native density (density < 0), player-capsule clearance, later-bore deferral, and neighboring-passage capsule checks. Mouth support also blends back the native field and its relief under another capsule check. The overlapping-coil tile exercises the later-bore and neighboring-capsule paths.
At W1, the ordinary FI tile (2,-2,-93,lod0) had 81,816 support-segment visits and 33,422 capsule checks, with no later-bore or other-capsule checks. The overlapping-coil tile (1,-2,-92,lod0) had 181,956 visits, 93,034 capsule checks, 3,219 later-bore checks, and 2,442 other-capsule checks. These counts matched L105. Both tiles also had identical L105/L106 density, mesh, payload, and topology hashes.
No local floor candidate was emitted, so candidate-specific crossing and capsule-clearance deltas are not measured. For a minimal hybrid, precompute route-floor geometry in the tile field while retaining the native-density gate, both capsule checks, later-bore deferral, and mouth restoration. This can remove route projection work without changing those support rules.
Boundary bands: added a per-tile XY-column cache for active transition pairs. It serves exact lattice XY only; off-grid queries still call the original exact calculation. The FI profile measured 681,651 column/pair evaluations, 4,530,549 lattice cache hits, and 75,758 exact off-grid fallbacks. A seam-centered profile measured 623,891 evaluations, 2,578,260 hits, and 21,328 fallbacks.
Verification
- Exact hashes: 24/24 Clang/GCC × W1/W8/W12 × SW/FI/TN/VS runs matched L105 tile and whole-view hashes; zero mismatches. Source stamp:
a033e6b53537f3550549a7a77f93f5a5d6594263c208cbbffc5d403f6d7ad7b5. - Fast tier: PASS, 274 checks, 269 PASS, 5 historical diagnostics, 0 failures. Walkability, capsule clearance, support, floor/mouth profiles, route binding, and headroom gates passed.
- L80 readiness: the required 3-pair medians are below. Near and whole sets completed in every cell.
| Stratum | Near W8 | Near W12 | Whole W8 | Whole W12 |
|---|---|---|---|---|
| SW | +4.8% | −0.6% | +8.7% | −1.1% |
| FI | −4.2% | +0.1% | −1.5% | +0.6% |
| TN | −3.4% | −2.4% | −2.0% | −1.5% |
| VS | −2.3% | −2.4% | −1.2% | −1.1% |
Readiness was noisy. A second full 3-pair set produced FI W12 deltas of +11.9% near and +7.6% whole; a focused 3-pair FI W12 retest measured −0.9% and −0.5%. All three result sets are under Saved/Linux/l106/readiness-paired*; I do not claim a consistent readiness speedup.
- Captures: visually checked all nine L105/L106 pairs; every pair had 0 changed pixels. Listed views:
passage/0-1/0,passage/1-2/0, andpassage/2-3/0, each at upper mouth, lower mouth, and mid-50. The contact sheet shows every pair; exact PNG paths are inSaved/Linux/l106/captures/summary.json. - Unreal Linux Development build: PASS, 27/27 actions,
-NoUBA -MaxParallelActions=4, after timing and withoutprlimit. - FI Unreal arrivals: 3/3 PASS, each settled 1,216 near tiles in 1.543–1.550 s from first admission. They ran with
taskset, withoutprlimit.
No world behavior changed, so the evaluator version remains 216. No commit, push, or stash was made.
