+- Mid-task: runtime shows where work is (`做到哪`); do **not** treat chunk progress as the user-facing final answer.
+- `AGENT_SYSTEM`: no `report_done` / final wrap-up until the task is actually complete; mid-flight plain text must be labeled partial — prefer continuing tools.
+- CLI `run` / `agent`: final Done/Answer printed as blank line + `〔結論〕…`; Blocked keeps recovery hint. Progress stays on stderr.
