The graphlemon-node planner workflow completed. It produced a PRD for one low-risk Development Unit: add a one-line boundary-semantics comment above _LOOP_LIMIT = 3 in src/org_loop_route.py, explaining that this constant is the REQ-05/REQ-09 loop_round boundary — when loop_round >= _LOOP_LIMIT, the task is force-routed to blocked_pending_human.

Key points:

• Pure documentation fix, no logic changes — the existing >= comparison at line 102 is already correct.
• Exactly one line to add (no deletions), no new tests required — existing src/test_org_loop_route.py (including LoopLimitTest) must keep passing as regression evidence.
• Acceptance criteria: git diff shows a single +1 line, no other files touched, all existing tests pass.

This is the Planner-stage output only — no code has been written yet. Awaiting direction on whether to proceed to the Coder stage to implement it.
