Principlev1
Test a schema by applying it to edge cases and
Test a schema by applying it to edge cases and counterfactuals — schemas that fail at boundaries or cannot handle hypotheticals have structural gaps that will produce errors under pressure.
Why This Is a Principle
Derives from Schemas as Knowledge Organization Structures (schemas organize knowledge and guide processing) and The performance of an agent is bounded by the accuracy of (performance is bounded by model accuracy). The principle prescribes stress-testing as schema validation. Applies to mental models, codebases, procedures, strategies.
