-## Target-State GameManager
-
-`GameManager` does not exist in the current implementation. The following pattern is target-state guidance only and should not be applied until the manager exists in code.
-
-```ts
-export class GameManager {
-  cinematic!: CinematicManager;
-  audio!: AudioManager;
-  zone!: ZoneManager;
-
-  private constructor() {
-    this.cinematic = CinematicManager.getInstance();
-    this.audio = AudioManager.getInstance();
-    this.zone = ZoneManager.getInstance();
-  }
-}
-```
-
-When a `GameManager` exists, components and hooks should access other managers through it:
-
-```ts
-// Correct
-GameManager.getInstance().cinematic.play("intro");
-
-// Wrong — never import sub-managers directly in components
-CinematicManager.getInstance().play("intro");
-```

-In that target-state manager, every `set*()` method calls `this.emit()` to notify subscribers.
+Managers that expose state to React call `this.emit()` from every `set*()` method that changes subscribed state.

-  const [state, setState] = useState(game.getState());

 ## Rules
 
 - Do not add a `GameManager` unless the feature requires a real shared gameplay state owner.
-- Current managers may be imported directly until the target-state orchestrator exists.
+- Current managers may be imported directly.
 - Keep singleton managers limited to side-effect services or shared interaction state.
 - Always call `destroy()` on cleanup when a manager owns external resources.
 - Never create manager instances with `new` — always use `.getInstance()`.

-- **Player Position** : Position X, Y, Z du joueur en temps réel
-- **Zone Visualization** : Anneaux visuels au sol pour les zones + cylindres transparents
-
----
-
-## Notes techniques
-
-- Le mouvement du joueur est bloqué tant que `canMove` est `false`
-- Le store Zustand (`useGameStore`) est la source principale de vérité
-- `GameStepManager` synchronise automatiquement avec le store Zustand lors des transitions
-- Les transitions via les zones utilisent `GameStepManager.transitionTo()` qui met à jour le store
-- L'audio utilise un callback `onEnded` pour déclencher les transitions automatiques

 - This is still a prototype, not a complete game runtime.
-- The repair-runtime toggle is stored in settings and displayed in the UI, but the repair game currently still runs locally in React/Three.
-- `useRepairMovementLocked()` currently returns `false`, so the movement-lock rule and indicator are present but disabled on `develop`.
+- `useRepairMovementLocked()` locks player movement during focused repair steps and drives the repair movement indicator.
 - Production editor persistence does not exist. Save endpoints in `vite.config.ts` are local Vite dev-server helpers.
 - The player uses octree collision while gameplay objects use Rapier. Keep that boundary deliberate unless the whole player controller is migrated.

 In `fragmented`, the repair object is rendered with `ExplodableModel`, then automatically advances to `scanning`. In `scanning`, the exploded model remains visible, a blue scan visual moves from part to part, and a red halo/wire marker plus the configured broken UI video stay attached to configured broken parts after the scanner reaches them. The scan matches configured broken parts by `nodeName` and reports diagnostics when a configured node is missing. In `repairing`, the case opens in a larger focused transform, `RepairCaseModel` traverses the case GLTF for empty nodes named `placeholder_*`, several grabbable replacement parts appear on those slot positions, and releasing a part near a slot snaps it into place with a short GSAP animation. Scanned broken parts are also rendered as grabbable objects and must be deposited into a compatible slot before the final install target validates. If `brokenParts[].caseSlotName` is configured, that broken part snaps only to the matching slot; otherwise it can use any available slot. If the current case asset has no slot nodes, the flow keeps using fallback focus positions and logs the fallback. Replacement parts show green or red placement feedback after snapping, broken parts show stored feedback after deposit, and the install target gives a short blocked feedback if the player tries to validate too early. The install target only validates when the configured correct replacement part is placed and all scanned broken parts have been deposited. In `reassembling`, the exploded model animates back into its assembled position with green completion particles before the flow moves to `done`. In `done`, the repaired object remains visible with a completion target; validating closes the repair case first, then plays the case exit animation before advancing the global mission progression.
