//! Read-only diagnostic tooling: consistency checking, revision
//! differencing, node history, and node search.
//!
//! These build on the reader and never modify the store. Each returns a
//! structured result so a caller — the `froe` command line or another
//! program — can render or process it. Traversal is bounded against
//! cyclic corrupt records, matching the rest of the crate.
