| 1 | """Supercharged tests for ``muse rebase`` — TDD for all gaps. |
| 2 | |
| 3 | Covers every JSON output path for: |
| 4 | - ``duration_ms`` (float, milliseconds) |
| 5 | - ``exit_code`` (int, 0/1/3) |
| 6 | - ``replayed_commit_ids`` (list[str], sha256:-prefixed) |
| 7 | |
| 8 | Covers sha256:-prefix correctness: |
| 9 | - ``_resolve_ref_to_id`` with sha256:-prefixed content in ref files |
| 10 | - ``_short_id`` keeps the sha256: prefix and truncates only the hex portion |
| 11 | - ``new_head``/``onto`` in JSON are sha256:-prefixed |
| 12 | |
| 13 | Covers all integration and lifecycle paths: |
| 14 | - completed (normal), aborted, up_to_date, conflict, dry_run, status, squash |
| 15 | |
| 16 | Security, performance, and stress: |
| 17 | - symlink guard on REBASE_STATE.json (load, save, clear) |
| 18 | - size cap on REBASE_STATE.json |
| 19 | - 50-commit dry-run, concurrent status reads |
