FR-CFG-004 — Environment Inheritance

Go to Crucible Configuration Management Requirements

Crucible SHALL derive an Infrastructure Configuration from an identified parent Infrastructure Configuration.

This requirement derives from:

• Crucible System Requirements Specification, Version 1.1 Draft, Functional Requirements, Configuration Management, FR-CFG-004

The Original Requirement states:

The system SHALL support environment inheritance models.[C1]

FR-CFG-004:

• Replaces The system with the defined system name Crucible
• Replaces the weak phrase support environment inheritance models with the observable behavior derive
• Identifies an Infrastructure Configuration as the subject of inheritance
• Identifies a parent Infrastructure Configuration as the source of inherited configuration content

Environment inheritance allows related Infrastructure Environments to share common configuration content.

A derived Infrastructure Configuration uses configuration content from an identified parent Infrastructure Configuration rather than duplicating the complete configuration.

This approach reduces configuration duplication and promotes consistency among related Infrastructure Environments.

This requirement applies to:

• Crucible
• Infrastructure Configurations
• Parent Infrastructure Configurations
• Derived Infrastructure Configurations
• Infrastructure Environments

Verification confirms that:

1. A tested Infrastructure Configuration identifies a parent Infrastructure Configuration
2. Crucible derives the tested Infrastructure Configuration from the identified parent Infrastructure Configuration
3. The derived Infrastructure Configuration contains configuration content obtained from the identified parent Infrastructure Configuration
4. The relationship between the derived Infrastructure Configuration and its identified parent can be determined

Implemented and Verified

Review and approve FR-CFG-004 as a leaf requirement.

Determine whether Environment Inheritance requires a controlled definition in the shared Terms and Definitions corpus.

Determine whether separate requirements define overrides, inheritance depth, conflict resolution, or inheritance from multiple parent Infrastructure Configurations.

This requirement page retains the stable requirement identifier FR-CFG-004.

This page is a leaf requirement page and omits a trailing :start from its namespace.

The Statement preserves the approved source intent by requiring Crucible to derive an Infrastructure Configuration from an identified parent Infrastructure Configuration.

Do not add explicit override behavior, conflict resolution, inheritance depth, multiple-parent inheritance, validation, approval, deployment, revision history, provenance, or traceability obligations to the Statement unless the controlling requirement changes through an approved requirements process.
