From 7661fe9d24e2af6e7c8d777bb70084d86ba7562b Mon Sep 17 00:00:00 2001 From: Fr0zka Date: Thu, 8 Oct 2026 22:50:54 +0200 Subject: [PATCH] wip(unreal): round 5 (stopped early) -- all 15 passage/strate probes walkable 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.
