Extraction is a two-phase process of chunking followed by parallel lens extraction, and it uses lenses for facts, definitions, procedures, requirements, and specifications plus profiles such as general and pharma-manufacturing so that extraction can be specialized by lens and domain.

**Extraction:** Two-phase (chunking → parallel lens extraction), lenses (facts, definitions, procedures, requirements, specifications), profiles (general, pharma-manufacturing)
