## Corpus Check
- Large corpus: 230 files · ~285,449 words. Semantic extraction will be expensive (many Claude tokens). Consider running on a subfolder, or use --no-semantic to run AST-only.

## Summary
- 4867 nodes · 26935 edges · 39 communities detected
- Extraction: 31% EXTRACTED · 69% INFERRED · 0% AMBIGUOUS · INFERRED: 18500 edges (avg confidence: 0.6)
- Token cost: 0 input · 0 output
