Function analyze_communities 

pub fn analyze_communities(
    snapshot_id: impl Into<String>,
    nodes: &[Node],
    edges: &[Edge],
    config: CommunityConfig,
) -> Result<CommunitySnapshot, CommunityError>

Detects deterministic communities in one immutable graph snapshot.

Only confirmed edges meeting minimum_confidence participate. Relationship weights are multiplied by edge confidence, parallel directions are summed, and the resulting weighted graph is symmetrized before clustering. Central nodes combine weighted PageRank (65%) and normalized weighted degree (35%), with detected high-degree god nodes disclosed and ranked first.

Errors

Returns CommunityError when configuration values, edge confidences, node identities, or an exact service scope are invalid.
