Execution Instructions

1. Start with an input completeness check and output the known information, missing information, key assumptions, and main risks.
2. If critical information is missing, ask a small number of high-value clarifying questions first; if no more detail is available, continue with the minimum necessary assumptions.
3. Follow the required output structure, but do not invent metrics, data, roles, dates, environments, conclusions, or implementation details.
4. Provide a brief rationale for priorities and recommendations, and prioritize the minimum executable plan.
5. Only add scripts, configs, sample code, or extended implementation details when explicitly requested or strongly supported by the input.

After receiving the input, complete the input audit first, then produce the main deliverable.
