+The planner work node finished investigating the suspected `loop_round > 3` off-by-one bug. Summary:
+
+**Conclusion: the bug doesn't exist.** `src/org_loop_route.py:102` already uses `>= _LOOP_LIMIT` (limit=3), matching the spec text in `docs/sdd/04-P-流程与状态流转.md:20`. The `> 3` wording only appears in `docs/self-development-feasibility.md:50`, an explicitly-labeled hypothetical illustration for PH5 self-hosting feasibility — not a real bug report or the spec itself.
+
+It produced a Benchmark-style verification document (scenario groups A/B/C — boundary tests at `loop_round=2/3`, cross-task isolation, `manual_resume`, and a doc/code consistency check), all backed by existing passing tests in `src/test_org_loop_route.py`. It flagged two minor, non-blocking coverage gaps (an explicit test at `loop_round=2`, and repeating the boundary check on the `full_replan` branch) as optional follow-ups, not new Development Units.
+
+It also raised two open questions it deliberately left for a human decision rather than deciding unilaterally:
+1. Should the gated real self-hosting E2E (`RUN_REAL_SELF_HOSTING_E2E=1`) be run? Its default recommendation: no — PH5 isn't in scope yet per CLAUDE.md, and there's no real bug to exercise it against.
+2. Was "verified no bug exists" the desired outcome, or was the intent to hand it a real bug for a full fix-and-close loop? If the latter, this task shouldn't be considered closed — a new task with an actual defect description would be needed.
+
+No code changes were made and no new Development Unit was created, since no real defect was found. Next step is up to the user: resolve the two open questions, or ask to fold the suggested test additions (A3/A4) into `src/test_org_loop_route.py` anyway.
