The graphlemon planner workflow (task w14ck9zm3) completed. It produced a BRD scoping a single, low-risk change: add one clarifying comment above `_LOOP_LIMIT = 3` in `src/org_loop_route.py`, explaining it's the loop_round boundary required by REQ-05/REQ-09 (docs/sdd/06-验收与测试锚点.md) that triggers `blocked_pending_human`.

Scope: one file, one new comment line, no logic changes, no other files touched, no new tests needed (existing regression tests already cover the behavior). Acceptance: `git diff` shows exactly that one added line, and `src/test_org_loop_route.py` still passes.

The PL self-review concluded this is unitary and low-risk enough to hand directly to the Coder agent without further breakdown. No code has been changed yet — this was the Planner stage only; awaiting direction on whether to proceed to implementation.
