# Framework Layer

The static, universal component of the TLCTC JSON architecture containing threat cluster definitions, generic vulnerabilities, data risk events, bow-tie model principles, attack path notation rules, and framework axioms. Defined in `tlctc-framework.json`. Changes rarely (only during framework evolution) and serves as the common language that all organizations reference. Contrasts with the Intelligence Layer which contains dynamic, incident-specific data.
