  1. Foundation
    • Project registry and boundaries
    • Shared standards, security controls, and reusable patterns
  2. Execution
    • Implementation rules and controlled AI-assisted workflows
    • Verification gates and testing requirements
  3. Continuity
    • Decision records, evidence, reports, and clean handoffs
    • Project-specific context kept separate across systems

Output: Individual applications and systems built on top
