The system evaluates the teacher and the model.
Most AI evaluation infrastructure measures what the model produces. FieldRules starts earlier: what quality of human reasoning is the model being conditioned by? Every rule has an IF/THEN trigger and a reasoning field that holds the practitioner's judgment in her own words at the moment the rule is made. That domain expert reasoning is treated as first-class semantic material: scored, elicited, and governed differently from the structural clauses, even where it sits next to them in the schema.
