| `RUSTFS_HEAL_OVERLAP_POLICY` | `merge` (`DEFAULT_HEAL_OVERLAP_POLICY`) | `merge` dedups an admin heal start that overlaps a running or queued heal; `minio_error` returns a typed already-running / overlapping-paths rejection like madmin. |
| `RUSTFS_HEAL_OVERLAP_POLICY` | `merge` (`DEFAULT_HEAL_OVERLAP_POLICY`) | `merge` reuses the token of an equivalent active, queued, or retrying admin heal; incompatible same-target starts and intersecting admin scopes return `already_running` / `overlapping_paths`. Durable-only owners reject until recovered or replaced with `forceStart`. `minio_error` also rejects equivalent starts and preserves overlap rejection against background tasks. |
