# Code Review: parametrize-base-branch

## SPEC coverage

| Req | Status |
|-----|--------|
| R1 — _gate_worktree_drift reads base_branch | ✓ `_base_branch(cfg)` in git diff argv |
| R2 — Helper: None→main, empty→main+WARN, non-str→str+WARN, explicit→explicit | ✓ |
| R3 — Bad-revision still WARNING-skip | ✓ unchanged |
| R4 — Template includes base_branch | ✓ |
| R5 — No new deps | ✓ |

## Cross-script impact

No impact on loop-runner.py. Only status.py and the template.

## Verdict

PASS.
