====== FX Logical Change Control ======

[[dido:99_annexes:annex-b-terms-and-definitions:start|Return to Terms and Definitions]]

===== Discussion =====

FX Logical Change Control governs changes to FX logical definitions, relationships, responsibilities, constraints, lifecycle states, and interaction patterns.

FX Logical Change Control supports review before a change affects inherited Part 2 logical elements, FX-specific specialisations, implementation profiles, deployment profiles, testability plans, or [[dido:99_annexes:annex-b-terms-and-definitions:e:evidence|Evidence]] expectations. It identifies the changed element, the reason for the change, the affected FX logical relationships, the compatibility impact, the [[dido:99_annexes:annex-b-terms-and-definitions:t:traceability|Traceability]] impact, the governance impact, and the [[dido:99_annexes:annex-b-terms-and-definitions:e:evidence|Evidence]] impact.

FX Logical Change Control helps prevent local changes from silently altering inherited meaning. A change to an FX logical information structure, [[dido:99_annexes:annex-b-terms-and-definitions:l:logical_communication_endpoint|Communication Endpoint]], lifecycle state, [[dido:99_annexes:annex-b-terms-and-definitions:l:logical_node_role|Node Role]], [[dido:99_annexes:annex-b-terms-and-definitions:r:runtime_plane|Runtime Plane]] classification, policy constraint, or interaction pattern affects producers, consumers, governance relationships, [[dido:99_annexes:annex-b-terms-and-definitions:t:traceability|Traceability]], and [[dido:99_annexes:annex-b-terms-and-definitions:e:evidence|Evidence]] expectations.

===== Definition =====

//Governance of changes to FX logical definitions, relationships, responsibilities, constraints, lifecycle states, and interaction patterns.//

===== Source =====

Specialization of [[dido:99_annexes:annex-b-terms-and-definitions:l:logical_change_control|Logical Change Control]] from Part 2, Section 11.5, and [[dido:99_annexes:annex-b-terms-and-definitions:g:governance_and_authority|Governance and Authority]] from Part 1, Section 9.6; generalised from FX governance and change-control concerns in the original FX Demo Reference Architecture.

===== Note =====

FX Logical Change Control protects the FX logical meaning before implementation or deployment details change.

===== Example =====

A change to the [[dido:99_annexes:annex-b-terms-and-definitions:f:fx_validation_result|FX Validation Result]] definition triggers review of affected validation logic, semantic interpretation, contract state processing, audit records, provenance records, replay expectations, and [[dido:99_annexes:annex-b-terms-and-definitions:e:evidence|Evidence]] expectations.
