The merge surfaced what main's new script-flags gate was written for: two
gospel-resources entries advertised --poison inside an inline # comment, where
the shell drops it — a self-test that never runs is a gate certifying itself.
Each flag now has a runnable sibling entry (check:snapshot-guard:poison,
check:coverage-consistent:poison) and the prose points at the entry instead of
the raw flag. Both siblings executed: the injected defects are caught (12/12
clauses). capability-exemplars regenerated; full build green, 34/34 post gates.
