1//! Identity-graph extraction: which service-to-service RBAC edges does this
2//! workspace's configuration require? (spec §8.2)
3//!
4//! Edges are derived from the actual resource files — data source connection
5//! strings, knowledge-base model wiring, agent→knowledge-base grounding, and
6//! encryption key references. `rigg auth doctor` verifies and repairs them.
