lib/tests/run-review-guards.sh — 5 whole-surface guards that RED if a banned
pattern subsists anywhere, auto-run by make test (run-*.sh glob):
G1 trailer (A1), G2 false CLAUDE.md attribution (A5), G3 strict-YAML frontmatter
(A4), G4 reconcile hermeticity (job3 B1), G5 hook-drift installed==emit (A2).
This is the check that would have caught A1/A4/A5/A2 at make-test time instead of
an adversarial review — the series' recurring failure was fixing one instance and
leaving twins. G3/G5 degrade to SKIP if pyyaml/emit-hook absent (portability).
Teeth verified: a planted trailer in a real agent REDs G1. Review fil rouge.
