# Profile Communities
Community structure of the corpus co-author graph.
## How to run
```bash
aiwg corpus profile-communities
aiwg corpus profile-communities --out indices/communities.md
```
Uses **label propagation** (deterministic variant — no `python-louvain`
dependency; the graceful fallback the corpus tooling specifies), reports
**modularity Q** (warns when Q < 0.3 = weak structure on a sparse graph), and
lists **bridge authors** (highest betweenness, spanning communities).
## Triggers
- "detect research communities"
- "co-author clusters / modularity"
- "bridge authors"
- `/profile-communities`
