The Knowledge Layer is a governed semantic knowledge base that maintains approved claims, brand constraints, verified features, and documented proofs. Unlike a traditional content database, the Knowledge Layer is not a passive archive but an active layer that powers AI generation and validates its output.
Each knowledge item in the layer has a reliability tier (1-4, where 1 is official/primary and 4 is user-generated), an approval status for generation (approved_for_generation: true/false), and a human review required flag (requires_human_review).
This approach ensures that AI does not invent arbitrary claims, but only draws from a verified and traceable semantic perimeter.
