| 1 | """Cross-command integration tests for the Muse plumbing layer. |
| 2 | |
| 3 | These tests chain multiple plumbing commands together the way real agent |
| 4 | pipelines and scripts would, verifying that the output of one command is |
| 5 | correctly consumed by the next and that the whole chain is self-consistent. |
| 6 | |
| 7 | Pipelines tested: |
| 8 | - hash-object → cat-object → verify-object (object write/read/integrity) |
| 9 | - commit-tree → update-ref → rev-parse (commit creation end-to-end) |
| 10 | - pack-objects → unpack-objects round-trip (transport) |
| 11 | - snapshot-diff → ls-files cross-check (diff vs. manifest consistency) |
| 12 | - show-ref → for-each-ref consistency (ref listing cross-check) |
| 13 | - symbolic-ref → rev-parse → read-commit (HEAD dereference chain) |
| 14 | - merge-base → snapshot-diff (divergence analysis) |
| 15 | - commit-graph → name-rev (graph walk + naming) |
