Sigma Runtime is governed runtime infrastructure for long-horizon AI systems.

Rather than treating AI as isolated model inference or stateless orchestration, Sigma Runtime provides the runtime layer that preserves continuity across extended operation.

The architecture focuses on behavioral stability, memory provenance, governed interaction with external systems, deterministic action validation, multi-agent exchange boundaries, contradiction handling, and trajectory safety.

Sigma Runtime can operate through its own interface or integrate into existing AI systems through runtime APIs, allowing organizations to build long-running AI workflows without coupling governance to a specific model, provider, or orchestration framework.
