| The Financial Systems Archetype separates [[dido:99_annexes:annex-b-terms-and-definitions:r:runtime_plane|Runtime Plane]]s to preserve architectural clarity. That separation does not mean the planes operate in isolation. A [[dido:99_annexes:annex-b-terms-and-definitions:f:financial_system|Financial System]] often requires interactions across planes, but those interactions need to remain explicit, [[dido:99_annexes:annex-b-terms-and-definitions:t:traceability|Traceable]], and governed. | The Financial Systems Archetype separates [[dido:99_annexes:annex-b-terms-and-definitions:r:runtime_plane|Runtime Plane]]s to preserve architectural clarity.

| For example, a health event in the [[dido:99_annexes:annex-b-terms-and-definitions:h:health_and_observability_plane|Health and Observability Plane]] may trigger a recovery command in the [[dido:99_annexes:annex-b-terms-and-definitions:c:control_plane|Control Plane]].
