Luna, round 5 goal 1 only (stopped by owner decision before the SurfaceWorld port):
- Worm and Cascading passages now pass walkability; the wide floor stays clipped while the
narrow route core stays open.
- Hidden third failure found and fixed: long VerticalShafts diagonal legs were dropped from
Core's spatial bins by a 100,000-bin safety cutoff (invisible to density queries);
conservative bins restore them (18,570/18,570).
- All 15 saved probes pass a walkability-only gate; build-time walkability gate added.
NOT re-verified before the stop: W1/W8/W16 hashes, BuildHost UBT/actor run.
