Control Planes

Autonomous systems need a control plane above individual agents and workflows. Without that layer, each actor may execute valid local actions while the larger system loses coherence.

A control plane observes, coordinates, constrains, and intervenes. It does not replace the execution layer. It regulates it.

Why Individual Agents Are Not Enough

An individual agent may know its task, tools, and local context. It may not know the full authority model, system state, cost envelope, policy boundary, or downstream impact of its action.

A multi-agent system adds more complexity. Agents can delegate, interpret, retry, compensate, and modify shared state. Without a higher-level control plane, the system may lack a stable place to evaluate coherence.

Control Plane Responsibilities

A control plane may provide:

• System-wide observability.
• Policy checkpoints.
• Authority resolution.
• Delegation tracking.
• Veto and hold mechanisms.
• Escalation routing.
• Rollback and containment triggers.
• Audit trail consolidation.
• Federation health signals.

Control Plane And Governance Plane

The governance plane is the part of the control plane that handles policy, authority, accountability, auditability, escalation, and constraint management.

The distinction matters because not every control-plane function is governance. Some functions coordinate execution, route work, or manage state. Governance is the portion that asks whether the action should proceed, under what authority, with which constraints, and with what record.
