• Common usage in software development emphasizes lifecycle model with iterative risk loops.

Capabilities

• Capabilities reflect repeated functions the artifact can perform in practice.
• Selections remain provisional and tied to current corpus evidence.

Composition

• Reasoning structure is not primary in the current characterization.
