 ===== Statement ===== ===== Statement =====
  
-[[dido:99_annexes:annex-b-terms-and-definitions:c:crucible|Crucible]] SHALL represent the desired state of each [[dido:99_annexes:annex-b-terms-and-definitions:i:infrastructure_environment|Infrastructure Environment]] through declarative configuration without prescribing the sequence used to create the environment.+[[dido:99_annexes:annex-b-terms-and-definitions:c:crucible|Crucible]] SHALL define [[dido:99_annexes:annex-b-terms-and-definitions:i:infrastructure|infrastructure]] through [[dido:99_annexes:annex-b-terms-and-definitions:d:declarative_configuration|Declarative Configuration]].
  
-===== Source Statement =====+===== Derived From =====
  
-> The system SHALL define infrastructure through declarative configuration.+This requirement derives from:
  
-===== Source =====+  * Crucible System Requirements Specification, Version 1.1 Draft, Functional Requirements, Configuration Management, FR-CFG-001
  
-Crucible System Requirements Specification, Version 1.1 Draft, Functional Requirements, Configuration Management, FR-CFG-001.+The Original Requirement states:
  
-===== Assessment =====+> //The system SHALL define infrastructure through declarative configuration.//[[dido:02-crusible:99-annexes:annex-b:cr-001|[C1]]]
  
-The source statement expresses the approved functional intent but does not provide all information required for deterministic verification.+FR-CFG-001 replaces **The system** with the defined system name [[dido:99_annexes:annex-b-terms-and-definitions:c:crucible|Crucible]].
  
-The following Specification Discipline and Authoring findings apply: +No other substantive normalization is required.
- +
-  * **The system** does not use the defined system name +
-  * **Define infrastructure** does not identify the infrastructure representation or required result +
-  * **Infrastructure** does not identify the infrastructure object represented by the declarative configuration +
-  * **Declarative configuration** does not explicitly distinguish desired state from an execution procedure +
-  * The source statement does not identify the observable result used to verify compliance +
- +
-The normalized Statement: +
- +
-  * Replaces **The system** with the defined system name +
-  * Identifies the [[dido:99_annexes:annex-b-terms-and-definitions:i:infrastructure_environment|Infrastructure Environment]] as the represented object +
-  * Identifies desired state as the required content +
-  * Distinguishes declarative representation from the execution sequence used to create the environment +
- +
-The normalized Statement does not introduce configuration validation, approval, application, versioning, deployment, or history obligations. Separate requirements govern those behaviors when required.+
  
 ===== Rationale ===== ===== Rationale =====
  
-Declarative configuration describes the required state of an [[dido:99_annexes:annex-b-terms-and-definitions:i:infrastructure_environment|Infrastructure Environment]] rather than a sequence of commands or procedural actions. +[[dido:99_annexes:annex-b-terms-and-definitions:d:declarative_configuration|Declarative Configuration]] defines the required [[dido:99_annexes:annex-b-terms-and-definitions:i:infrastructure|infrastructure]] without requiring the configuration to prescribe the procedural steps used to realize it.
- +
-A declarative representation identifies what the resulting environment should contain or satisfy while allowing an implementation or deployment tool to determine how to realize that state. +
- +
-This separation allows different implementation technologies to process the same infrastructure intent without embedding a technology-specific execution procedure in the configuration. +
- +
-Declarative infrastructure configuration contributes to: +
- +
-  * Platform independence +
-  * Configuration reuse +
-  * Consistent environment representation +
-  * Desired-state comparison +
-  * Reduced dependence on manual procedures +
-  * [[dido:99_annexes:annex-b-terms-and-definitions:r:reproducibility|Reproducibility]]+
  
-Other requirements establish machine-readable representation, version control, reusable blueprints, inheritance, and configuration history.+This separation allows infrastructure definitions to remain independent of the implementation tools and execution mechanisms used to create or modify the infrastructure.

 ===== Verification ===== ===== Verification =====

 ===== Referenced By ===== ===== Referenced By =====
  
-The wiki Backlinks function provides the current list of pages that reference ''FR-CFG-001''.+The following pages reference this requirement:
  
-Incoming traceability should be derived dynamically from backlinks rather than maintained as a duplicate manual list. +{{backlinks>.#dido:02-crusible}}
- +
-Backlinks identify incoming references but do not define the semantics of each relationship. Referencing pages should identify whether the relationship represents realization, refinement, verification, dependency, or another defined traceability relationship. +
- +
-===== ConOps Relationship ===== +
- +
-The Crucible Concept of Operations describes Phase 1 as a command-line utility invoked through [[dido:99_annexes:annex-b-terms-and-definitions:c:ci_cd_pipeline|CI/CD Pipeline]] steps. +
- +
-Declarative configuration provides the desired-state representation consumed by the workflow while allowing provider implementations and external deployment tools to determine the execution sequence required for each target platform. +
- +
-This separation preserves infrastructure intent independently from the implementation procedure used to create an Infrastructure Environment.+

 ===== Notes for Editors ===== ===== Notes for Editors =====
  
-This requirement page should retain the stable requirement identifier ''FR-CFG-001''.+This requirement page retains the stable requirement identifier ''FR-CFG-001''.
  
-Changes to the Statement SHALL preserve the approved intent of the source requirement.+This page is a leaf requirement page and omits a trailing '':start'' from its namespace.
  
-Material changes should receive review and should update the related outbound traceability, verification criteria, and source records.+The Statement preserves the approved source intent and changes only the actor from **The system** to the defined system name [[dido:99_annexes:annex-b-terms-and-definitions:c:crucible|Crucible]].
  
-The Source Statement should preserve the original wording from the controlling System Requirements Specification. +Do not add desired-state representation, Infrastructure Environment identification, execution-sequence constraints, validation, approval, versioning, deployment, or history obligations to the Statement unless the controlling requirement changes through an approved requirements process.
- +
-Verification criteria should test only the declarative representation behavior defined by the Statement. +
- +
-Configuration validation, approval, application, version control, revision history, deployment, and evidence preservation should not be introduced as normative behavior on this page unless the Statement changes through an approved requirements process. +
- +
-Incoming traceability should use the wiki Backlinks function rather than a manually maintained list.+
