+## Dungeon Race exit regression (2026-09-26)
+
+- `src/app/dungeonRaceStore.test.ts` covers immediate cleanup of active and
+  practice races, cancellation during an in-flight queue request, ordered
+  server leave before requeue, and an old preparation response after start.
+- `scripts/playtest-dungeon-race-exit.cjs` used headless Edge with a fresh
+  online account. It left an NPC race through the pause menu, entered an
+  ordinary Bite-Sized dungeon without a race HUD, and requeued into a new
+  online match without an “already in a race” error. Screenshots are in
+  `playtest-artifacts/dungeon-race-exit/`. The offline practice playtest also
+  left after a modeled loss, confirmed the local race state cleared, and
+  started practice again. Browser page errors were absent in both passes.
