The graphlemon-node planner workflow completed. It produced a single-file, single-line SDD: add one boundary comment directly above `_LOOP_LIMIT = 3` in `src/org_loop_route.py`, explaining that `loop_round >= _LOOP_LIMIT` forces `blocked_pending_human` (tying it to REQ-05/REQ-09 in docs/sdd/06-验收与测试锚点.md). No logic, interface, or schema changes — 7 git-diff-verifiable acceptance criteria were defined, and rollback is a single `git checkout`. The SDD is ready to hand off to a Coder node (DU-01); let me know if you'd like me to proceed with that edit.
