Principlev1
Validate schemas at progressively larger scales, holding
Validate schemas at progressively larger scales, holding constant what has already been tested while introducing one new variable or context at a time.
Why This Is a Principle
Grounds to Mental Models Are Singular by Default (single mental model construction), The behavior of a system arises from its structure, not from (system behavior arises from structure), and Learning occurs when outcomes differ from predictions, (learning occurs when outcomes differ from predictions). The principle prescribes incremental validation where each test isolates one change, enabling attribution of results. This counters the single-model bias while producing higher-resolution diagnostic information when schemas fail.
