10.7 Acknowledge Control Command

Go To Top

The Acknowledge Control Command pattern allows a Logical Node to report receipt, acceptance, rejection, completion, failure, or outcome of a Logical Command.

A command-consuming Logical Node produces a Logical Acknowledgement. The acknowledgement identifies the original command, the acknowledging Logical Node, the acknowledgement status, timestamp, reason, resulting lifecycle state, and provenance or Evidence reference.

The interaction belongs primarily to the Logical Control Plane. It also supports the Logical Health and Observability Plane when the acknowledgement reports operational state, and the Logical Audit and Provenance Plane when the architecture records command outcome.

Table 10-6: Acknowledge Control Command logical interaction pattern

Element	Logical treatment
Primary Runtime Plane	Logical Control Plane
Producing Logical Node Role	Command Consumer, Managed Node, Worker Node, or Controlled Node
Consuming Logical Node Role	Command Producer, Control Node, Coordinator, or Operator-facing Node
Primary information	Logical Acknowledgement
Supporting information	Command identifier, acknowledgement status, reason, timestamp, resulting lifecycle state
Traceability expectation	Acknowledgement traces to the original command, acknowledging Logical Node, outcome, and related lifecycle state.
Evidence expectation	Acknowledgement record supports review of command handling and operational accountability.
