ECR-000002 Analysis Plan

Within Artifact Family

Compare:

• canonical versus paraphrased versus structural
• graph_only where available
• recognition rate
• structural stability
• primitive stability
• constraint stability
• AST stability
• canonical summary stability

For P001, compare P001C structural against P001D graph_only specifically to isolate topology-level recognition sensitivity.

Across Artifact Type

Compare:

• reasoning versus execution versus static
• control-flow shape
• loop and branch richness
• termination conditions
• product relevance patterns

Across Models

Compare:

• GPT versus Claude versus Gemini
• literal agreement
• dimensional agreement
• recognition differences

H016-Focused Check

For P001D, record whether recognition persists after lexical reduction has been pushed below the P001C level.

Comparator Guidance

Use the existing ECR-000001 comparator v3 approach if practical.

This ECP does not require new comparator tooling.

Interpretation Boundary

No hypothesis confidence updates should occur without human review.
