The placer probe in RS001's stale-branch diagnosis (scripts/check-issue-resolution.sh) names the last base-side commit that touched the record's terminal path after divergence, as evidence that the base placed the record there after the branch forked. Any touch qualifies, so a body edit of a record that was already terminal at the merge base reports 'placed there on main's side by <sha> … rebase' when the honest verdict is 'terminal before this branch diverged; drop the trailer'. The probe should key on the commit that ADDED or renamed the path into the terminal folder (--diff-filter=AR) or compare the merge base's tree, not on any touch. Separately, the base-side commit subject is interpolated into the stderr message unsanitised; a subject carrying terminal control sequences would reach the terminal through the gate's output. Found by the ruthless review of the hygiene branch; left open as a follow-up.

Grounds

• pursued: a trailer naming a record terminal before the branch diverged is told to drop the trailer and a truly stale branch is still told to rebase naming the placing commit; the existing stale-branch and terminal-before-divergence cases going red would show it wrong
