Purpose

Derive explicit evaluation criteria from the research objective and candidate set.

Input contract

required: [research_objective, candidate_set, decision_context]
optional: [stakeholder_priorities, measurement_constraints, candidate_domains]
constraints: [criteria must be mutually interpretable across candidates]

Procedure

1. Extract desired outcomes and constraints from the objective.
2. Translate them into candidate-discriminating criteria with definitions and units.
3. Check completeness, overlap, direction, and measurability.
4. Return the criterion schema and unresolved measurement questions.
