18 scenarios that verify the security script's rules still
trip on every tripwire — PATs, AWS keys, PEM headers, env
files, allowlist exempts, confidentiality terms, marketing
phrases, .security-allow exclusion, plus message-mode
(Conventional Commits, DCO, Claude trailer, banned phrases).
Wired into the security workflow as a second-line gate after
the diff-based check. Catches the refactor-weakens-a-rule
class of regression: the diff scan can be green while a rule
silently no-ops; the harness fails loudly when that happens.
