Summary
GitBook is your architectural and conceptual home — explaining how Q402, Governance, and RWA integrate into the AI Autonomy Stack. GitHub is your engineering workspace — hosting the live code, SDKs, facilitator logic, and deployment scripts.
Together, they provide a full-stack environment for developers, institutions, and autonomous agents to build intelligent, verifiable, and frictionless systems on-chain.
