ccd-case-systems

name	ccd-case-systems
description	Linguistic case formally typed as an analytic category — CaseRole, Morphism, AlignmentFunctor, MonoidalFunctor, Natural Transformations. Crucial for §2 core topology, downstream §7c DAIF alignment, and §9b adversarial injection formal verification.

When to use

• Defining, comparing, or mathematically grading case inventories and cross-linguistic functors.
• Evaluating DAIF Surprisal (N400/P600) using CaseCategory.assess_daif_surprisal().
• Validating adversarial NLP topological bindings (ACC -> NOM) via src.security.cognitive_security.CaseFrameValidator.validate_assignment().
• Checking Fibrational F(A⊗B) tensor preservation with MonoidalFunctor against multi-turn chain-of-thought hijacking.
• Verifying a natural transformation with NaturalTransformation.naturality_holds().
