| 1 | """Tests for ``muse count-objects`` — object store diagnostics. |
| 2 | |
| 3 | Coverage tiers: |
| 4 | - Unit: _count_loose_objects, _collect_reachable_ids helpers |
| 5 | - Integration: empty store, single object, multi-shard, verbose breakdown, |
| 6 | --unreachable counts GC candidates, JSON schema, text format, |
| 7 | objects match expected after N commits |
| 8 | - End-to-end: full CLI via CliRunner |
| 9 | - Security: read-only — no mutations; no content reads (stat only) |
| 10 | - Stress: store with many objects; --unreachable on multi-commit repo |
