+## Handplant bail and delayed revert crash (8 September)
+
+The supplied run entered HandPlant at tick745 and WipeoutGround at746, then
+stopped at tick1318 on the missing PhysicsGround -> RevertGround adapter.
+HandPlant incorrectly used FootPlant collision checks with unconditional trick
+impact limits (stock XZ0.1/Y0.6). It now dispatches the native Air(false) checks,
+including their contact, difficulty, cooldown and actual danger-state gates.
+The original bail reason was not recorded, so the causal gameplay result still
+requires a user retest. PLANT_BAIL now records reason indices and collision/pose
+observations when either plant requests a bail.
+
+RevertGround102 now owns Enter82D43488, Update82D43518, empty Exit, Ground
+Post82D4C070 and Fill82D43B10. It loads the five fields from stock class
+018E8A2E5028AB3F, captures approach velocity after the authored delay, applies
+the directed rotation-speed curve, manual/anti-flip corrections and pumping,
+and publishes active State66 for the existing selector's normal exit.
+No gameplay execution was performed during this repair.
+
+Validation for this repair: six core wipeout tests and two revert numerical
+tests passed. Two pre-existing game test fixtures were updated for their current
+map-menu and render-material API signatures so these tests could compile.
