From 44984780d472fe227981ec60ebddd3dccb26c810 Mon Sep 17 00:00:00 2001 From: VinPropane Date: Sun, 12 Apr 2026 00:59:40 -0400 Subject: [PATCH] NEON-29: Widen TerracePlatformA approach treads past capsule width. Tread run was 0.45 m vs 0.8 m capsule diameter, causing straddle stuck on stairs and blocked motion toward edges when exiting. Use 1.0 m depth (NS/WE boxes), recenter PAS_* transforms flush to the lip. Tighten NavigationAgent path/target desired distance 0.35 to 0.22. --- client/README.md | 2 +- client/scenes/main.tscn | 36 +++++++++++------------ docs/plans/NEON-29-implementation-plan.md | 2 +- 3
