| 1 | """End-to-end bidirectional roundtrip tests for ``muse bridge``. |
| 2 | |
| 3 | This module creates a realistic, *complex* git repository from scratch — |
| 4 | multiple branches, realistic file trees, multiple authors, conventional commit |
| 5 | messages, semver tags — then exercises the full bridge cycle: |
| 6 | |
| 7 | Git → (git-import) → Muse → (git-export) → Git |
| 8 | |
| 9 | Each direction is verified for content fidelity, commit count, and bridge |
| 10 | state consistency. A second pass adds new commits in git and re-imports |
| 11 | (incremental), then adds Muse-native commits and re-exports, confirming that |
| 12 | the bridge correctly accumulates history on both sides without duplication. |
| 13 | |
| 14 | Test organisation (eight tiers): |
| 15 | |
| 16 | Tier 1 — Fixture Sanity the git repo we build is what we think it is |
| 17 | Tier 2 — Full Import git→muse, all content arrives correctly |
| 18 | Tier 3 — Full Export muse→git, Muse commits visible in git |
| 19 | Tier 4 — Bidirectional import then export then re-import cycle |
| 20 | Tier 5 — Incremental new git commits → incremental import |
| 21 | Tier 6 — Muse-Native Round Muse-only commits survive git-export |
| 22 | Tier 7 — Data Integrity file content SHA-256 match end-to-end |
| 23 | Tier 8 — Drift Tracking bridge status drift counters are accurate |
| 24 | |
| 25 | NOTE: ``git`` subprocess calls in this file are INTENTIONAL and necessary — the |
| 26 | bridge command translates *from* git repos. All other Muse code paths are |
| 27 | git-free. See ``docs/bridge-ci.md`` for CI requirements. |
