Digital Biosphere Architecture is organized as a five-layer stack for increasingly autonomous AI systems.
POP defines portable persona objects and identity-facing attachment across runtimes.
Agent Intent Protocol defines machine-readable intent, action, and result objects for coordination.
Token Governor defines runtime control surfaces such as policy, budget, fallback, and pre-execution checks.
MVK focuses on execution integrity and verification-relevant runtime truth.
ARO-Audit packages bounded evidence and receipts for later review, replay, and audit workflows.
- Persona says who is acting.
- Interaction says what is being requested or attempted.
- Governance says what is allowed.
- Execution integrity says what actually happened.
- Audit evidence says what can be reviewed and exported.
