+## Bite-Sized spawn floor regression (2026-09-26)
+
+- Fresh offline Dungeon Race practice entries in Wailing Caverns and Utgarde
+  Pinnacle previously settled about 0.5 m below the visible floor. During the
+  race start gate, Rapier physics was paused while PlayerRig accumulated
+  downward movement. Holding the player controller for that gate removed the
+  stored fall. Wailing keeps its original entrance; Utgarde now starts on the
+  connected Skadi wave corridor with three source first-wave guards.
+- `scripts/playtest-bite-sized-spawns.cjs` entered both dungeons through the
+  menu, waited for content, intro, and race gate completion, then sampled five
+  seconds of play. Wailing was grounded at y=-31.016 from a -30.92 spawn;
+  Utgarde was grounded at y=104.812 from a 104.8 spawn. Both kept their entry
+  X/Z position, and there were no browser page errors. Before/after screenshots
+  and `result.json` are in `playtest-artifacts/bite-sized-spawns/`. The player
+  stands visibly on the floor in both after screenshots. Utgarde corridor samples
+  at z=370, 390, 410, 430, 445, and 460 also stood on collision in the live
+  client; the source guard points and boss position have collision and
+  navigation surfaces.
