Function traverse 

pub fn traverse(
    nodes: &[Node],
    edges: &[Edge],
    request: &TraversalRequest,
) -> Result<TraversalReport, QueryError>

Finds confirmed paths using the requested bounded traversal strategy.

Non-confirmed edges are never traversed. Encountered inferred, ambiguous, stale, or incomplete edges are returned separately as unresolved candidates.

Errors

Returns QueryError for invalid graph identities, dangling endpoints, missing anchors, invalid confidence values, invalid costs, or unsupported limits.
