Principlev1
Document the schema that generated a failed prediction along
Document the schema that generated a failed prediction along with the prediction itself, so you can identify which specific assumptions or variables were wrong rather than just noting the error.
Why This Is a Principle
Derives from Generative Externalization (externalization is generative), Externalization Exposes Hidden Structure (externalization exposes gaps), and Knowledge that exists only in tacit form degrades without (tacit knowledge degrades). This principle prescribes documentation structure that enables diagnostic analysis rather than just outcome tracking.
