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.
