Per upstream review on #8235: no future-fix runbook, no line-number inventory, no 'new rows always carry a thread scope' claim (STRICT comment_thread_root_id leaves assignment-level handoff rows NULL by design), and #8229's real rejection reason recorded (unsafe at production data volume, nothing to gain). Supersedes #8235.
Docs-only, zero behavioral change. HYP-1760 / HYP-1750.
