The "graphlemon-node-816ae6b60f11493b8d329c118a3756e1" workflow (planner) completed. It produced a Benchmark/Acceptance Test spec for Development Unit DU-01 — a comment-only change to src/org_loop_route.py adding a REQ-05/REQ-09 boundary note above `_LOOP_LIMIT = 3`.

Spec contents:
- Scope guard (G1–G4): diff must touch exactly one file, add exactly one comment line directly above `_LOOP_LIMIT = 3`, nothing else changes (docstring, other constants, function bodies).
- Scenario 1 (happy path): comment must reference REQ-05, REQ-09, the docs/sdd/06-验收与测试锚点.md anchor doc, and state the rule `loop_round >= _LOOP_LIMIT` → `blocked_pending_human`.
- Scenario 2 (boundary): comment must attach unambiguously to `_LOOP_LIMIT`, not neighboring constants.
- Scenario 3 (regression): `python3 -m unittest src.test_org_loop_route` must stay fully green before/after — no new tests needed since it's doc-only.
- Scenario 4 (over-scope check): confirms nothing outside the single comment line changed.

I did not persist this as a committed artifact — src/artifact_write.py requires a DB connection, task_id, and produced_by_run_id that weren't supplied to this session, so I avoided fabricating them. Next step, if desired: proceed to the coder step for DU-01, or wire this into the artifact pipeline with real IDs.
