Criteria before conclusions
Define the decision, authority, mandatory constraints, evidence threshold and evaluation criteria before models see the preferred answer.

Define the decision, authority, mandatory constraints, evidence threshold and evaluation criteria before models see the preferred answer.
Test alternatives, counterfactuals, missing communities, sensitivity to weights and evidence that could reverse the ordering.
Preserve sources, assumptions, unresolved questions, minority positions and the named human approval boundary.

Review the Trust Center and Accessibility statement before treating the service as procurement-ready.
The responsible agency, official or board remains accountable for data quality, statutory duties, consultation, equity analysis, professional review and the final decision. 3Dogs output is decision support and may be wrong, incomplete or unsuitable for a particular jurisdiction.
