# Analogy Extraction

Extract transferable structural principles from source domains.

## Stages

### Stage 1: Source Identification

Identify candidate source domains using domain-scanning SOP. Evaluate each for structural similarity depth (surface/structural/systemic).

### Stage 2: Abstraction

For each promising source, extract the abstract principle using abstraction-extraction or biological-strategy-extraction SOP. Strip domain-specific details to reveal the transferable mechanism.

### Stage 3: Structural Mapping

Map source structure to target domain. Identify: corresponding elements, missing elements (gaps), extra elements (opportunities). Use structural-mapping SOP.

### Stage 4: Transfer Validation

Assess mapping quality: Is the analogy surface-level (shared labels) or deep (shared relational structure)? Use analogy-quality-assessment SOP. Only deep analogies warrant transfer.

## Minimum Yield

| Metric | Floor |
|--------|-------|
| Source domains scanned | ≥5 |
| Abstractions extracted | ≥3 |
| Structural mappings completed | ≥3 |
| Validated deep analogies | ≥2 |
