fix(pylon): start post-ebike delay in tampon state

Update repair-game.md to reflect the recent flow refactor:
- single ExplodableModel mounted across fragmented -> done
- splitSpeed for slower, more deliberate explosion
- ebike repairing simplified to a single 'Changez le refroidisseur' trigger
- ebike done auto-completes on narrateur_ebikerepare's ended event
- narrator ownership table clarified (narrator vs scan sequence vs repair game)

+The mission object is shown split apart. `RepairGame` mounts a **single** `ExplodableModel` instance for the entire repair flow (`fragmented` -> `done`) so the model loads once, animates from its real authored positions, and is never re-instantiated when the player advances to scanning, repairing, reassembling or done. This eliminates the visible position/rotation jumps and re-explosion that occurred when each step instantiated its own model.
 
 `ExplodedModel.createParts` walks the GLTF tree recursively, descending through any single mesh-bearing wrapper node (e.g. `Scene > Moto > Eclatement` for the Ebike) until it reaches a node with multiple mesh-bearing children. Those children are the natural "explosion groups" authored by the modeler. This avoids exploding raw leaf meshes in local space when the model has extra empty wrapper nodes above the intended group.
 
-When mounted, `RepairGame` applies `RepairMissionConfig.modelRotation` and `modelScale` to the fragmented model so it lines up with the source inspection model in world space (e.g. the parked Ebike using `EBIKE_WORLD_ROTATION_Y` / `EBIKE_WORLD_SCALE`).
+When mounted, `RepairGame` applies `RepairMissionConfig.modelRotation` and `modelScale` to the shared model so it lines up with the source inspection model in world space (e.g. the parked Ebike using `EBIKE_WORLD_ROTATION_Y` / `EBIKE_WORLD_SCALE`). The explode/reassemble lerp speed is configurable via `splitSpeed` (default `REPAIR_FRAGMENT_SPLIT_SPEED = 1.8`, ~1.5s) so each node is clearly seen leaving its origin.
 
-The default delay comes from:
+Transition out is event-driven: the model fires `onSplitSettled(1)` when the lerp converges and `RepairGame` advances to `scanning`. A `REPAIR_FRAGMENTATION_SEQUENCE_SECONDS + 2` fallback timer guards against load failures.

-The scan sequence:
+The scan sequence is now stateless w.r.t. the model: it receives `parts: ExplodedPart[]` from the upstream shared `ExplodableModel` and:
 
-- keeps the exploded model visible
-- receives model parts from `ExplodableModel`
 - advances an active part index over time
 - renders `RepairScanVisual` on the active part
-- reveals broken-part highlights when configured broken parts have been reached
+- reveals broken-part highlights cumulatively as scan progresses
+- when the active part has a `voiceLineId`, gates the advance on the audio's `ended` event (with a 15s ceiling fallback) so the diagnostic line plays in full
 - returns `RepairScannedBrokenPart[]` when done
 
-Broken-part lookup first tries `brokenParts[].nodeName`. If no configured node matches, it falls back to the first available exploded parts. This fallback is useful while GLTF node names are still unstable, but precise `nodeName` config is safer for production.
+Broken-part lookup uses `brokenParts[].nodeName` against the exploded parts (deep traverse). When a configured node can't be matched, the available part names are logged so config drift is visible in the console.

+## Narrator Audio (Ebike Mission)
+
+`EbikeRepairNarrator` (`src/components/game/EbikeRepairNarrator.tsx`) is a headless component mounted in `src/pages/page.tsx` next to `EbikeIntroSequence`. It subscribes to `useGameStore` and plays one-shot narrator cues at specific repair-step transitions for the `ebike` mission only:
+
+| Step entered | Dialogue ID                          | Audio file                         | Subtitle | Owner                  |
+| ------------ | ------------------------------------ | ---------------------------------- | -------- | ---------------------- |
+| `fragmented` | `narrateur_galetscan`                | `narrateur_galetscan.mp3`          | cue 6    | `EbikeRepairNarrator`  |
+| `scanning`   | `narrateur_refroidisseur_diagnostic` | `narrateur_refroidisseurcassé.mp3` | cue 24   | `RepairScanSequence`\* |
+| `done`       | `narrateur_ebikerepare`              | `narrateur_ebikeréparé.mp3`        | cue 7    | `RepairGame`\*\*       |
+
+\* The diagnostic line is triggered by the scan sequence when it lands on the broken part configured with `voiceLineId` (refroidisseur for ebike). The advance to `repairing` is gated on the audio's `ended` event so the line plays in full with the red highlight on screen.
+
+\*\* `RepairGame` plays the success line directly on entering `done` so the audio's `ended` event can drive `completeMission` and hand off to pylon. A `REPAIR_DONE_DIALOGUE_FALLBACK_MS` timer guards against load failures. `EbikeRepairNarrator` no longer owns this cue.
+
+A `useRef<Set<MissionStep>>` guards against double-fires (StrictMode, re-renders) and is cleared when the mission rolls back to `locked` or `waiting`, so debug-panel replays still trigger the narration.
+
+Cue 7 was previously a single subtitle covering both the diagnostic line and the "Eeeet voilà!" completion line. It was split into cue 7 (completion only) and a new cue 24 (diagnostic) so the two sentences can be triggered at independent moments — they correspond to two distinct `.mp3` files.
+
+The breakdown line (`narrateur_ebikecasse`, cue 5) is still triggered by `EbikeIntroSequence` at distance threshold, not by this component. Pylon and farm narrator cues are not yet wired through `EbikeRepairNarrator`; the same per-mission lookup pattern can be extended when those flows need narration.
