| 1 | """Stress tests for CommitRecord, SnapshotRecord, TagRecord, and provenance fields. |
| 2 | |
| 3 | Covers: |
| 4 | - CommitRecord round-trip through to_dict/from_dict for all format versions. |
| 5 | - format_version evolution: missing fields default correctly when reading old records. |
| 6 | - reviewed_by (ORSet semantics): list preserved, sorted, deduplicated via overwrite_commit. |
| 7 | - test_runs (GCounter semantics): monotonically increases via overwrite_commit. |
| 8 | - agent_id / model_id / toolchain_id / prompt_hash / signature fields. |
| 9 | - SnapshotRecord round-trip with large manifests. |
| 10 | - TagRecord round-trip. |
| 11 | - get_head_commit_id on empty branch returns None. |
| 12 | - write_commit is idempotent (won't overwrite). |
| 13 | - overwrite_commit updates the persisted record correctly. |
| 14 | - read_commit for absent commit returns None. |
| 15 | - list_commits and list_branches. |
| 16 | - list_tags returns all tags. |
