//! Regression harness for repeated reconcile over sqlitegraph-core.
//!
//! This exercises the same large Rust tree that exposed daemon-side reconcile
//! failures in local service runs. The test is ignored by default because it
//! depends on the developer workspace layout and performs a full scan + replay.
