| Field | Value |

| **Why chosen** | Needed the first failing acceptance coverage to pin the v1 `format-ranges` contract across Core and MCP before the feature could be implemented confidently. |
| **Mode** | `sync` |
| **Why this mode** | The coordinator needed the acceptance shape and no-partial-apply assertions fixed before implementation and review. |
