 The LK sample data is fetched on demand into `data/ofmx_lk/` via `scripts/fetch_ofmx.sh` and is ignored by git.
 
 Airspace records in the LK sample reuse `AseUid/@mid`, so `ofmx.airspaces.ofmx_id` is not unique. The schema uses a composite uniqueness constraint on `(ofmx_id, region, code_id, code_type, name)` to preserve distinct entries while keeping imports idempotent.
+
+## Roadmap
+- Expand parser coverage for additional OFMX features (procedures, routes, obstacles).
+- Add integration tests that validate full imports against a disposable PostGIS instance.
