| 1 | """Tests for ``maestro.muse_cli.artifact_resolver``. |
| 2 | |
| 3 | Covers: |
| 4 | - ``test_resolve_artifact_working_tree`` — existing file path resolves directly. |
| 5 | - ``test_resolve_artifact_from_commit`` — commit-ID prefix resolution via DB. |
| 6 | - ``test_resolve_artifact_file_not_found_exits_1`` — non-existent path exits 1. |
| 7 | - ``test_resolve_artifact_ambiguous_prefix_exits_1`` — multiple commit matches. |
