The graphlemon Work Node (planner) workflow completed. It produced a Benchmark/验收测试文档 for DU-01 ("打通执行日志真实写入路径" — fixing Bug A1: empty execution logs never written to disk, and Bug A2: the log-download endpoint crashing with an uncaught FileNotFoundError). The document defines 9 test scenarios (BM-01 through BM-09) covering happy-path log writes, multi-node/retry/reflect-node isolation, and failure/quota/missing-file edge cases against `src/execution_log.py`, `src/work_graph_orchestrate.py`, and `src/backend_server.py`.

`git status` shows a clean working tree — no new commits were created, so this Benchmark content was returned as text only and has not yet been written into `docs/sdd/` or `.graphlemon/runs/`. No further action was taken since persisting or handing it to the Coder node wasn't explicitly requested.
