python-cli-install-init-contract-consistency
I diagnosed the bug, reproduced all four failures against the pre-fix baseline, verified the fix on the fixed tree, and wrote the deliverable to ~/solution.md.
The repo is totalwindupflightsystems/gitreins at 482526bb (fix commit 449282ee). Four independent defects produced the reported inconsistency:
install wrote guards.test_command: "pytest -x --tb=short". init detected uv run pytest -x --tb=short and printed it, but _fill_missing_guards() only fills missing keys, so the YAML kept the old value.
