Executive core
Prefrontal Node is the orchestration authority behind the SENTINEL direction. Its role is to coordinate planning, routing, policy checks, contracts, traces, provider use, and recovery signals.
Core responsibilities
- Route work across models, tools, providers, and workers.
- Preserve contracts between the operator surface and execution layer.
- Record useful traces for audit, diagnosis, and learning.
- Support policy gates around what a run can do.
- Help the system recover when work fails or drifts.
Public value
The Prefrontal Node story gives SENTINEL its control-plane identity: AI work is not just prompted; it is governed through a visible execution system.
