 //! 5. Monitor sync events on both cores
 //! 6. Validate data appears correctly in Core B's database
 //!
+//! ## Running Tests
+//!
+//! For most reliable results, run tests serially to avoid resource contention:
+//! ```bash
+//! cargo test -p sd-core --test sync_integration_test -- --test-threads=1
+//! ```
+//!
+//! Tests should pass when run in parallel, but may occasionally timeout under heavy load
+//! due to competing background tasks from 20+ concurrent Core instances.
