R16 declared-done without task_close: your last message claims the task is complete, but there is an open protocol_task. Close it now with nexo_task_close(sid=..., task_id=..., outcome='done', evidence='<substantive proof>', files_changed='...'). Evidence must be >= 50 chars AND not a single filler word (R03 validator will reject empty / 'ok' / 'done' / 'fixed'). If the work is partial, close with outcome='partial' and outcome_notes instead. Do not produce visible text for this reminder — act on it. After handling the silent action, continue with your previous task; this reminder is silent context, not a new instruction.
