Investigation of the two tests that had been failing for days (Codex; the fix reviewed and its
field claims re-run by me).
Real bug, introduced by adb34df: gap chunks take the compact bedrock path in GetDensityAt, which
applied the passage modifier but never the build-authored native D-floor. So the walkable passage
floor vanished exactly at the gap/strate seam, in the passages the player uses to cross strates.
Now gap chunks set Result = -Density, then ApplyPassageNativeFloorMC, then VF_ApplyXYEdgeSealMC.
The seal runs on the MC value, in the same order as before.
Stale tests, not code bugs:
- PassageLandsInOpenSpace: since d97373c production passes the cached world/warp seed to
VF_SuggestLandingPoint, while the test still queried with the default seed. Both queries are
fixed; the test now allows only exact graph-owned support-floor samples (the production
bProtectAuthoredTunnelFloor contract), and anything else still fails. 14/14 landing ends,
5,774/5,774 floor and capsule samples.
- ClassifyTileSoundness: since d38d4ca ClassifyTile covers the cell vertices g=0..CPA, but the test
still sampled the mesher's outer normal halo. Both "holes" were halo-only (g = CPA+1). The test now
asserts the current contract. TryProveSealedSolidTile already uses the exact core lattice, so it
is not affected.
Verified: crossing test PASS (max gate 0.129 s); sealed-proof test 22/22; both classifier variants
pass (600 tiles each). Re-run by the orchestrator against this build: export OBJ SHA-256
b3e5f4c3..9b377 unchanged; capability 20,830 / 10,909 / walk-only 10,909.
Ledger: one DDC startup fatal (crash folder 43101DC8, 04:38) and a set of expected diagnostic
failures while locating the gap-branch omission; one malformed ablation argument (not a valid
ablation).
