MECE

Make the whole visible: readers should know the distinct matters and where each detail goes.

Choose mode from the request:

• Review. If sibling boundaries already answer the document's question, report the basis, evidence, and bounded gaps, then stop.
• Proposal. For an existing document that needs restructuring, return the new outline, a source mapping, and a structural check; request approval and stop before rewriting.
• Decomposition. For a new problem, return a two-level structure, known-item mapping, assumptions, and pending gaps with reasons.
