System Architecture

LIVRE OS is a layered system.

Each layer has a clear responsibility, minimal surface area, and a defined way to talk to the others.

This section answers:

• What are the main layers of LIVRE OS?
• Where does each component live (device, backend, chain)?
• How does data flow from identity → vault → proof → verifier?
• What are the allowed state transitions for an identity?
