Then call next_task with types: ["EVIDENCE_VERIFICATION"] and domains: ["environment"] until you are handed this task id, read the packet's own sources yourself, and answer with submit_task. Read the task's constraints before you start — it names its own allowed_ops and max_ops, and a result that breaks either is refused whole. If the finding is an absence, say what you covered in searched.
