Method — Capability Boundary

Scope Framing

This domain defines capability boundary as a structural concept. It describes the formal limit at which a system’s declared or operational capability ends.

The focus is conceptual demarcation. No evaluation of safety, regulatory status, contractual duty, or compliance posture is performed.

Conceptual Discipline

• Descriptive structural language only
• No prescriptive or implementation guidance
• No liability allocation statements
• No jurisdiction-specific interpretation
• No product or system assessment

Boundary Integrity

Capability boundary is treated as a transition concept between:

• Declared scope of functionality
• Operational reality under defined conditions
• Out-of-scope or undefined behavior

It is not a certification criterion, a risk grading tool, or a regulatory classification instrument.

Update Rules

Changes are permitted only when:

• The definitional boundary materially evolves
• Structural clarification is required
• Primary institutional frameworks materially affect terminology

Minor editorial corrections are not logged. Material updates require a version increment in /changelog/.
