Cross-family review (High + Medium + Low), all three reproduced before fixing:
High -- on a pull_request event actions/checkout lands on a synthetic merge commit whose
body the forge composes from the PR description, so a description ending in an example
marker armed a guard no author armed. Excluded merge commits from the range; merging main
into a PR branch is separately forbidden, so no author-written commit is skipped.
Medium -- a folded value (`no` + continuation ` yes`) was split into independent lines and
the continuation armed on its own, inverting the value the author wrote. Read with `unfold`
so the value is judged whole.
Low -- the module docstring promised fail-open while marker resolution deliberately fails
closed. The posture is right; the docstring was wrong. Documented as the one exception.
Both new negative controls verified red against the unfixed matcher. Decision record
amended to state the residual honestly rather than overclaim: a quoted example that is the
FINAL paragraph of an ordinary commit is a trailer by git's own grammar and does arm. What
the change buys is that discussing the marker can no longer disable anything.
