Concepts
Janus is a governance core for systems where humans, software, and AI participate in decision processes. It governs how system evolution is evaluated, recorded, and reconstructed (not business logic execution).

Architecture
Janus is structured as a layered architecture: Core defines canonical terms, log types, and event identifiers; runtimes execute governance evaluation without redefining Core meanings.

Governance Model
Janus Core Lite defines a deterministic pipeline separating domain activity from governance evaluation and accountable audit writing. The scope model ensures evaluation remains deterministic, traceable, and reproducible.
