Abstraction Governance

Purpose

Prevent infinite abstraction ladders.

New Abstraction Test

A proposed abstraction may be introduced only if it satisfies at least two of:

• explains disagreement that lower-level representations cannot explain
• improves prediction
• improves measurement reliability
• reduces complexity
• produces clearer kill conditions
• improves Clarity or EDF product design without acting as product validation

Examples

• Primitive
• Functional role
• Constraint
• AST
• Canonical grammar

Abstraction Retirement Rule

If an abstraction does not improve measurement, explanation, prediction, or product relevance after two evidence runs, it should be suspended.
