OMP Domain Profile: AI Governance Evidence Under Singapore's Model AI Governance Framework, MAS FEAT Principles, and the ASEAN Guide on AI Governance and Ethics

This document defines a domain profile of the Operating Model Protocol (OMP) for AI systems deployed in Singapore and the ASEAN region subject to the Singapore Model AI Governance Framework (Second Edition, 2020), the Monetary Authority of Singapore (MAS) FEAT Principles for financial services AI, and the ASEAN Guide on AI Governance and Ethics (2024). The profile -- designated SingapureMark -- specifies how OMP's deterministic routing invariant, Watchtower enforcement framework, and three-layer cryptographic integrity architecture generate the per-decision accountability evidence required by Singapore's model AI governance framework, satisfy the MAS FEAT Principles' named accountability and explainability requirements, and align with the ASEAN Guide's human oversight and consumer protection governance standards. The OMP core specification is defined in the Operating Model Protocol Internet-Draft (draft-veridom-omp).
