"""pass_review requires a matched, evidenced verification per acceptance
criterion — not just a count of arbitrary strings.

Live failure this closes: QA passed a rendered video shipping 3 of the
brief's 4 named scenes because nothing forced the reviewer to walk each
acceptance criterion individually. Mirrors the test idiom in
test_qa_ac_coverage.py, one level stricter: criteria_verified entries must
each match a real AC (by id or exact text) and carry substantive evidence.
