L5 Development, Deployment & Runtime Governance CTO + Head AI Platform 1st Line
L6 Compute & Infrastructure Governance Head Compute Gov + CISO 1st + 2nd Line

2. Three Lines of Defense + Key Roles

  • CAIGO: $2.8M annual budget, 12 direct reports, deployment halt authority

  • Compute Governance Office: 8-15 FTE

3. 11-Component Governance Stack

GS-01 through GS-11: AI Inventory Registry, Risk Classification Engine (12-dimension ARS v2.0), Policy-as-Code (482+ OPA rules), Model Validation Platform (SR 11-7), Runtime Monitoring, Tamper-Evident Audit Logging (Kafka WORM), KPI/SLA Panel (42 metrics), Incident Response, CI/CD HITL Gates (7-stage, 4 human), Runtime Escalation Engine (5 triggers), Data Governance Fields (14 mandatory)

4. Regulatory Crosswalk

  • 186 controls mapped across 6 frameworks with 847 total mappings

    • Timeline roadmap with workstreams
    • API Explorer (42 endpoints, 8 domain groups)
  • Registered in whitepaper suite + dashboard navigation

Testing
