+# Stage 6 event-driven PuzzleSystem
+
+Date: 19 August 2026
+
+Beads task: `goon-game-puzzle-events`
+
+## Contract
+
+`PuzzleSystem` is the deterministic owner of puzzle signal channels. Each frame,
+`GameView` submits data-bound source facts and consumes published transitions:
+
+- pressure and conductive-relay sources aggregate by channel;
+- toggle and timed sources react only to their own rising contact edge;
+- timed channels expire deterministically and can be rearmed;
+- `DoorController` has an explicit `CLOSED` or `OPEN` state and ANDs its required
+  channels;
+- controlled platforms read the same channel state as doors and rendering;
+- signal and door open/close transitions are immutable frame events;
+- diagnostics expose update and transition counts without mutating gameplay.
+
+`GameView` remains the geometry adapter: it detects player/body contact and
+conductive-body overlap, but it no longer owns toggle/timer maps or calculates a
+door's required signals. Door audio and camera focus consume `DOOR_OPENED` rather
+than comparing an ad-hoc previous aggregate.
+
+The existing JSON `signalId`, `requiredSignals`, `controlId`, duration, and mass
+bindings remain unchanged. Existing content validation still rejects missing
+sources before packaging.
+
+## Lifecycle
+
+Puzzle state has an immutable snapshot containing toggle and timed channels.
+Reset clears channels, source edges, door states, events, and diagnostics. Restore
+also seeds held-source edge activity, so recreating an Activity while standing on
+a toggle or timer does not activate it a second time. Pressure and relay state is
+recomputed from restored bodies and geometry without user feedback side effects.
+
+## TDD evidence
+
+Separate RED cycles covered the missing base contract, pressure aggregation,
+timed expiry/rearm, relay plus explicit AND-door transitions, immutable
+reset/save/restore, restored held-source edges, diagnostics, and the missing
+`GameView` integration hook. Every RED was followed by its focused GREEN before
+the next behavior was added.
+
+The focused Android test completes the level-3 production-input route, leaves the
+saw body on its pressure plate, and verifies an activated signal, a published
+door-open transition, and one open `DoorController` through read-only diagnostics.
+
+## Final gates
+
+- JSON validator: `10/10`, format `1`, physics `1`.
+- JVM: `89`, failures `0`, errors `0`, skipped `0`.
+- `lintDebug`, `assembleDebug`, `assembleDebugAndroidTest`: GREEN.
+- focused Android 16 pressure/door integration: `1/1` GREEN.
+- final unfiltered Android 16 matrix: `38/38`, failures `0`, errors `0`,
+  skipped `0`, `433.599 s`, on the exact final APK/test APK.
+- debug APK ZIP integrity: `unzip -t` GREEN.
+- debug APK SHA-256:
+  `adeed8b3959e2192e15917136e754e626cf06248bbba0dcd7596d55b2685e011`.
+
+The dedicated AVD was stopped after the final gate. No movement, collision,
+physics version, level geometry, or accepted solution signature changed.
