1. State the proposal and the decision it would change.
2. Identify at least one plausible alternative or rival explanation, then test
   which evidence would distinguish it from the preferred view.
3. Separate verified evidence, assumptions, unknowns, and claims that need a
   source. Check that terminology, scope, and success criteria mean the same
   thing throughout the proposal.
4. Review from adversarial, deep, and implementation perspectives: identify
   neglected stakeholders, boundary conditions, failure modes, dependencies,
   and whether the proposed mechanism actually produces the claimed outcome.
5. Name the highest-impact risk, including privacy, security, cost, quality, or
   reversal risk when relevant.
6. Define what observation would falsify the preferred conclusion and the
   smallest useful next check.
7. Give a calibrated recommendation: proceed, revise, defer, or reject. Do not
   present a confidence level higher than the evidence supports.
