L99 treated a missing exact-grid sweep sample as "no route here", so off-grid queries exposed the
FI/TN boundary band inside passage 1-2 (flat ceiling/floor). In-bound misses now evaluate the
exact route; a conservative route-feature bound still skips out-of-extent misses. Composition
order unchanged (graph -> bands -> passage -> stamps -> floor caps).
Comparison now counts added/removed crossings and triangles: 0/0 crossings on all four strates
(FI +56 triangles). 1-2 mid-tunnel: L98->L100 changes 32k px (L99 changed 1.14M).
Near-ready @W12 (L98/L99/L100): FI 2.62/1.78/2.05, TN 2.36/1.55/1.80, SW 1.17/0.95/1.04,
VS 1.16/1.03/1.08 s. All walk audits pass; 24/24 Clang/GCC W1/W8/W12 determinism; fast tier PASS.

Route plan unchanged. Per tile, route segments whose bounded influence (tube + 4 m) touches the
tile write min-combined tube distance (base sweep); relief/floor/mouth shaping only in the shell
(detail sweep); 0.5 m edge blend into the strate field. Near-ready @W12: SW 1.01->0.80,
FI 2.23->1.43, TN 2.18->1.37, VS 1.09->0.98 s; whole view FI 3.38->2.37 s. All passage walk
audits pass (21,425/21,425 canonical, 3/3 interfaces); 24-run Clang/GCC W1/W8/W12 determinism;
0 sign flips. Change: mean 0.02 cm / 0.05 deg; max 25.9 cm (passage walls/roofs ~3.5 m from
route, LOD2) and 49.8 deg (rock walls 13-25 m from routes, LOD2). Captures with diffs in
Linux99/captures. Fast tier PASS (v215 pins).

L74's passage bound omitted the 0.21 m wall relief and 0.20 m floor relief, so its whole-tile
proof was unsound in principle (no tested view hit it). Passage support is now bounded per route
segment by four parameter-subinterval boxes using Catmull-Rom derivative extrema, local max
radius and relief padding. Stratum slicing only at LOD0-2 in FI/VS. Legacy sub-tile block
certificates are audit-only (runtime version was slower). TN regression (-80,-20,-3218) kept.
Exact full-grid vs skip hashes on every tile, 4 views, Clang/GCC, W1/W8/W12; control caught;
80-camera sweep 0 violations. Whole view vs c67b200: SW -1.3%, FI -7.6%, TN -2.3%, VS +0.2%.
Compiles in the Linux UE host (VFHostEditor, 27/27 actions).

The compiled-analytic stratum interval now certifies a legacy tile uniform only when it stays
beyond the detail envelope (and smooth-min slack for solid) with no intersecting primitive,
edit, native field, composer candidate, passage or active transition; everything else fails
closed. The stream layer uses the proof for whole-tile skips; legacy sub-tile skips stay off
(two block proofs failed the falsifier in TN).
Falsifier: full-grid reference vs skip-enabled run, identical mesh/payload/topology hashes on
every tile of all four owner views, Clang and GCC, W1/W8/W12; 20-camera sweep per strate,
0 violations; a too-tight control changed 3/184/233/238 tiles and was caught.
Whole view (8 workers): SW 2.61->2.48, FI 7.18->5.05, TN 5.97->4.63, VS 2.70->2.40 s.

The L70 "2x SurfaceWorld GenerateTile in Unreal" was the instrument: the trace enabled
bCaptureVoxelForgeCoreHashesForValidation, which disables the native heightfield-band
shortcut and whole-tile skips (W1 same keys: 9.00 s hash-off vs 28.46 s hash-on). With
hashing off, Unreal and headless match at W8 within 1.2-2.5% (Core 14.42 s vs 14.26 s) on
identical tile keys. LOD0 p95 tail = real cost of non-empty passage tiles near the spawn mouth
(p50/p95 18.8/105 ms); most LOD0 tiles are empty.
verify.py reads its baselines from Standalone/Tools/verify/baselines/ instead of untracked
Saved/Linux. The 11 .vfmesh control meshes (~78 MB) are not committed yet (to be stored
compressed). Fast tier green.
