+# Stage 6 character state machine
+
+Date: 19 August 2026
+
+Beads task: `goon-game-character-states`
+
+## Contract
+
+`CharacterStateMachine` is a deterministic public model driven by the physics
+facts already owned by `GameView`: alive, grounded, velocity and facing. It
+publishes:
+
+- `IDLE`, `RUN`, `JUMP`, `FALL`, `DEATH` base states;
+- configured transient `TURN` and `LAND` states;
+- configured command states `INTERACT` and `STUNNED`;
+- priority `DEATH > STUNNED > INTERACT > locomotion`.
+
+The model does not own collision or movement and therefore does not change the
+accepted Stage 5 physics. Switch contact drives the production `INTERACT`
+transition. `STUNNED` has a public command and a tested animation contract; its
+production hazard source belongs to the Stage 6 hazards work.
+
+`PhysicsConfig` remains the single source for movement, coyote/input buffer,
+respawn and the new turn/land/interact/stunned durations. The config/level
+physics version remains `1` because no movement or collision constant changed.
+
+## Visual contract
+
+Every living state maps explicitly to a `VolunteerRig.Motion`. `TURN`, `LAND`,
+`INTERACT` and `STUNNED` change skeleton joints, so the states remain distinct
+without relying on color. Collision dimensions stay `62 x 100`.
+
+## TDD evidence
+
+Separate RED cycles covered the missing state model, airborne/death states,
+configured turn, configured land, interaction, stun priority, visual mapping,
+GameView automation integration and the regression where interaction could
+downgrade an active stun. Each RED was followed by its focused GREEN before the
+next behavior was introduced.
+
+## Final gates
+
+- JSON validator: `10/10`, format `1`, physics `1`.
+- JVM: `81`, failures `0`, errors `0`.
+- `lintDebug`, `assembleDebug`, `assembleDebugAndroidTest`: GREEN.
+- focused Android 16 state integration: `1/1` GREEN.
+- final unfiltered Android 16 matrix: `36/36`, failures `0`, errors `0`,
+  `720.578 s`, on the exact final APK/test APK.
+- debug APK ZIP integrity: `unzip -t` GREEN.
+- debug APK SHA-256:
+  `d25b7dd0a06cead0d514539773acd0a84ed92bf7c2510b9b880ded2f66508581`.
+
+The AVD was stopped after the final gate.
