OMP Domain Profile: Cross-Sector High-Risk AI Accountability Under the Colorado Artificial Intelligence Act (SB 24-205) and Alignment with NIST AI RMF 1.0

This document defines a domain profile of the Operating Model Protocol (OMP) for high-risk AI systems subject to the Colorado Artificial Intelligence Act (SB 24-205, effective June 1, 2026), which requires deployers of high-risk AI systems in consequential decisions affecting Colorado consumers to implement risk management programmes, provide consumer disclosures, conduct impact assessments, and implement discrimination mitigation measures. The profile -- designated ColoradoMark -- specifies how OMP's deterministic routing invariant, Watchtower enforcement framework, and three-layer cryptographic integrity architecture satisfy the Colorado AI Act's per-decision accountability obligations and align with the NIST AI RMF 1.0, providing a unified cross-sector accountability evidence architecture for the six Colorado AI Act consequential decision domains. The OMP core specification is defined in the Operating Model Protocol Internet-Draft (draft-veridom-omp).
