Support under chambers and 9 m approaches either refilled the bore or left the same 5 Surface World route + 2 upper chamber probes unsupported in all three variants (identical counts with or without support), so those probes are likely not under the support footprint. Also exposed an FI chamber content-band validation failure. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_016dhxM43dnWvUu2B5Ph1iG1

L153 — landing support did not pass
The third support shape still fails seed 2: five Surface World route probes and two upper chamber probes remain unsupported. The work stopped after three failed implementations, as required by the round instructions. L153 is not ready to promote.
Captures are at eye height for all six chambers. L151 and L153 camera positions match; the upper passage/0-1/0 pitch differs by 3.10° because its planned floor tangent changed. L153 capture quality passed 6/6. The manifest and reproducible capture command are in captures and RunL153Captures.py.
Change
WorldAssemblyEvaluatorVersion is now 240. The candidate adds a tapered support SDF under chamber floors and the first/last 9 m of route approaches. Surface landings anchor to native ground within a 2 m depth budget; cave and shaft landings use a 0.75 m budget. The support footprint tapers over 1 m and embeds 0.20 m. Bounds were expanded for the support depth.
The three seed 2 attempts used the same W8 Surface World command and differed only in support composition:
| Attempt | Source stamp | Change | Seed 2 result |
|---|---|---|---|
| 1 | 4c83a0a143d44b7b1f44758408fafa8d220390825a9a15cd48b5484e22c35a0c |
Add the support body after passage composition | Chamber support passed, but 99 route capsule samples became solid; interior_air=FAIL. Five Surface World route probes remained unsupported. |
| 2 | 663ab4fff5e4605a19d2a6242b1ba23fff230c143f5ae5e9d7ebc00a2b3cf5df |
Clip support by the full passage/chamber air union | Interior air passed with zero solid capsule samples, but the upper chamber had 2 unsupported probes and Surface World route support still had 5. |
| 3 | 4599aacdabb2940f223570a9a537723727989dd5236dfc084524e6dff55bc1dc |
Clip support by the bore field only, leaving chamber air out of the clip | Same 2 upper chamber and 5 route probes remained unsupported. This is the current working tree. |
Attempt 3’s final seed 2 summary is interfaces=3 passed=2, strate_routes=3, route_walkable=2, route_bindings=3, route_binding_failures=0, status=FAIL. The upper passage/0-1/0 chamber reports unsupported=2; the Surface World route reports unsupported=5. Tunnel Network and Vertical Shafts route support pass. The passage interior capsule audit passes with 0 solid samples out of 320,355 and all 3 interior negative controls detected. Shell, naturalness (3/3), mouth profile (3/3), ripple (3/3), and blocked-route controls pass.
The seam audit did not emit a result: the headless audit exits with code 10 after the failed passage summary. Seam status is unverified.
Checks
- Clang 19 build passed with
-ffp-contract=off, 4 jobs. Final source stamp:4599aacdabb2940f223570a9a537723727989dd5236dfc084524e6dff55bc1dc. git diff --checkpassed.- Focused seed 2 audit: failed the support gate as described above. Log:
Saved/Linux/l153/seed2-focused.log. - Fast tier: failed after 0.5 s on the first Floating Islands owner fixture. Its resolved-layout snapshot rejects
passage/0-1/0because the lower landing chamber does not fit inside its host content band. Log:Saved/Linux/l153/fast-tier.log. - Capture quality: 6/6 passed. Existing L151 before images were reused; the after images were rendered from the L153 candidate.
The 16-seed Tunnel Network and Vertical Shafts sweeps were not run after the seed 2 gate failed and the three support attempts were exhausted. The tile seam result is absent for the same early audit exit. GCC W1/W8/W12, Clang W1/W8/W12 determinism, L80 timing across four layers, and the Linux UE start plus 30 m/s run were not run. No v240 canonical baselines were promoted because the candidate fails seed 2 and the fast tier. No Unreal Source/ files changed.
Remaining risk
The support body can either preserve the passage interior or provide the required support at the Surface World upper landing in this seed, but the three tested compositions did not do both. The v240 evaluator change also exposes a Floating Islands chamber content-band validation failure in the fast tier. The implementation and baselines need a new premise before this round can pass.
