//! Integration tests for LMDB storage backends using the storage test harness.
//!
//! # Requirements
//!
//! - Feature flag `lmdb` must be enabled
//! - No external services needed (LMDB is an embedded database)
//!
//! # Running
//!
//! ```sh
//! cargo test --features lmdb --test lmdb_tests -- --test-threads=1
//! ```
//!
//! # Notes
//!
//! Each test gets a fresh temporary directory via `tempfile::TempDir`.
//! The LMDB environment is opened within that directory so tests are
//! fully isolated. `--test-threads=1` is required because LMDB only
//! allows one write transaction at a time per environment, and the
//! shared environment pattern (for `DataService` and `LinkService`
//! using the same env) needs sequential test execution.
