duckdb /Users/bob/ies/hatchery.duckdb -c "SHOW TABLES;"

# Query GitHub interactome
duckdb /Users/bob/ies/music-topos/gh_interactome.duckdb -c "SELECT * FROM repos LIMIT 10;"

# Check interaction entropy
duckdb /Users/bob/ies/music-topos/interaction_entropy.duckdb -c "SELECT COUNT(*) FROM interactions;"

## Scientific Skill Interleaving

This skill connects to the K-Dense-AI/claude-scientific-skills ecosystem:

### Graph Theory
- **networkx** [○] via bicomodule
  - Universal graph hub

### Bibliography References

- `general`: 734 citations in bib.duckdb

## Cat# Integration

This skill maps to **Cat# = Comod(P)** as a bicomodule in the equipment structure:

```
Trit: 0 (ERGODIC)
Home: Prof
Poly Op: ⊗
Kan Role: Adj
Color: #26D826
```

### GF(3) Naturality

The skill participates in triads satisfying:
```
(-1) + (0) + (+1) ≡ 0 (mod 3)
```

This ensures compositional coherence in the Cat# equipment structure.
