Execute a bounded Research Relay Task Packet in an isolated, evidence-first workflow. Use when the user provides or explicitly asks to execute a `research-task/v1` packet: validate the packet, research only the assigned questions, prefer direct and current sources, record conflicts and missing evidence, create a detailed Evidence Artifact, and return only a compact `research-result/v1` envelope to the Master. Do not use as a second project manager, do not redefine the Master's goals, and do not treat prior Worker chats or unstated project memory as task facts.
