# Referee Verdict: parametrize-base-branch

## Status: PASS

## Artifacts

SPEC, IMPLEMENTATION, CODE_REVIEW, BUG_REPORT, ADVERSARIAL_BUG_REPORT, DOC_REVIEW — all present.

## Acceptance

- R1-R5 satisfied. `_base_branch` handles None, empty, non-string types correctly.
- Bad-revision → WARNING skip (preserved from v1).
- Template ships `base_branch: "main"` by default.
- 495 passed (482 + 13, 0 regressions).
- Adversarial probes confirm no injection vector (list-mode subprocess.run) and no crash for non-string types.

## Verdict

PASS. Approve complete.
