```ts
dispose(): void;

Terminal and immediate. Parts wearing it fall back to the scene model's material. A rule or item that wears it keeps `{ materialId }` in its state, so an undo still moves; a new write that wears it resolves 'refused' with reason 'disposed' (spec section 3.4).

## Generic-API test (spec 3.1)

| Rule | Result |
| --- | --- |
| 1. Neutral name | pass: `dispose` names no product |
| 2. A precedent | not recorded: no ledger row (coverage.json) names this member or its owner |
| 3. Two apps, or labs | not recorded: no ledger row names this member or its owner |
| 4. The cheaper fix first | not recorded per member (Appendix B decides it per need) |
