Module cross_source_edges 

Cross-source graph edges — connects external data to code via the graph index.

When provider data (issues, PRs, DB schemas) references code files, this module creates IndexEdge entries that the graph index uses for related-file discovery.

Edge kinds:

• mentions — issue/PR body references a code file
• queries — code file queries a DB table
• documents — wiki page documents a code module
• resolves — PR resolves/fixes an issue

Scientific basis: Scale-free networks (Barabasi-Albert) — cross-source edges follow preferential attachment: files mentioned in many issues become graph hubs.
