This document specifies the behavioral security primitive Status-Selection Against Function (SSAF) and establishes normative requirements for its identification, evaluation, and control implementation across AI systems including large language models, agentic systems, and distilled or fine-tuned variants. It consolidates the findings of the nine prior publications in the SSAF Research Series into a single authoritative specification document, incorporating normative definitions, control requirements structured after NIST SP 800-53, an evaluation methodology, conformance criteria, a MITRE ATT&CK-style technique entry, and multi-framework reference definitions.
