Deleting a group's primary (delete_annotation, lift_annotation) or clearing a redaction mark with a group member (redact::clear_marks) now removes /IRT from each subordinate that stays and keeps its /RT /Group, as Acrobat desktop does. The kept member no longer refers to the deleted annotation, so a full save leaves the deleted one's content out. It is part of the same edit: one undo restores the group, /IRT included. lift_annotation's copy-only uses (the page beneath a dragged stamp or signature) only render the copy, so the change there is harmless. Each /IRT walk this PR relies on gets a test past its bound and a loop: group_primaries on an unsettled loop (render), comment_summary under a 100-deep chain of subordinates and a self-listed loop (engine), and deletion over a 200-deep thread and reply and group loops (annot). Review on #4358. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01Pq7HyCfwzyRXj4VfQAVVdv
