====== 5.7 Runtime Plane Discipline in Implementation ======

[[fxdemo:04-part:05-phase-0-implementation-principles:start | Go To Phase 0 Implementation Principles ]]

Phase 0 implementation work must preserve [[dido:99_annexes:annex-b-terms-and-definitions:r:runtime_plane|Runtime Plane]] discipline.

Implementation artifacts must distinguish Control Plane, Data Plane, Health and Observability Plane, Policy and Release Plane, and Audit and Provenance Plane concerns. A single implementation mechanism may address concerns from more than one plane, but it must still preserve the purpose, [[dido:99_annexes:annex-b-terms-and-definitions:t:traceability|traceability]], and review expectations associated with each plane.

This principle prevents implementation convenience from collapsing architectural concerns. A status report, control command, transaction record, policy decision, audit record, and provenance record may all move through implementation mechanisms, but each retains its Runtime Plane meaning.
