The graphlemon Work Node (planner) workflow completed. Result: the requested "loop_round off-by-one bug" does not exist in the current codebase.

- `src/org_loop_route.py:102` already uses `loop_round >= _LOOP_LIMIT` (correct), matching spec `docs/sdd/04-P-流程与状态流转.md:20` and existing unit tests `src/test_org_loop_route.py:95-111` (loop_round=3 blocks immediately, per REQ-05/REQ-09).
- The described bug is a known synthetic demo scenario documented in `docs/self-development-feasibility.md:48-62`, reused verbatim as the gated `goal_text` in `supervisor/test_self_hosting_e2e.py:206-269` (the PH5 self-hosting closed-loop E2E test) — not an independently observed defect. The workflow's own prompt matched that text verbatim.

The Planner declined to fabricate a fix or produce an SDD/Unit breakdown against a false premise, and instead returned a BRD (full text captured in the task notification) documenting the mismatch with three options for human decision:
1. Close as already-correct, no code change needed.
2. Treat as a PH5 self-hosting regression drill — run `python3 -m unittest src.test_org_loop_route` as evidence; separately, and only with explicit user approval, decide whether to trigger the real gated `RUN_REAL_SELF_HOSTING_E2E=1` closed-loop run.
3. Treat as an intentional test of the Planner's fact-checking — in which case producing this BRD (rather than a fake implementation plan) was the correct outcome.

No code was changed. Awaiting the user's choice among these paths before any further action.
