KeiSeiKit-1.0/_primitives/_rust/kei-registry/tests/index_substrate_smoke.rs

//! Integration smoke test for `index-substrate`.
//!
//! Creates a synthetic mini-kit, runs `handle_index_substrate`, verifies row
//! counts, then verifies idempotency (second run → 0 new) and supersede (one
//! file modified → 1 superseded, rest unchanged).
