Project Navi LLC Response to "Accelerating the Adoption of Software and AI Agent Identity and Authorization"

This document is Project Navi LLC’s response to the NIST National Cybersecurity Center of Excellence (NCCoE) concept paper “Accelerating the Adoption of Software and AI Agent Identity and Authorization” (February 2026). The response focuses on Sections 4 (Authorization), 5 (Auditing and Non-Repudiation), and 6 (Prompt Injection Prevention and Mitigation) for autonomous software-development agents. It proposes the IronClaw architecture: a three-container trust model (untrusted agent, hardened broker, privileged runner), a capability-lease data model, and an informed consent flow for human-in-the-loop authorization. The design is intended to align with OAuth 2.0/2.1, NIST SP 800-207 Zero Trust Architecture, and the Model Context Protocol (MCP), and is based on implementation experience within the navi-os platform.
