   - `.env.test` exports `TEST_DATABASE_URL`, `RUST_LOG`, `RUST_BACKTRACE`, and `RUST_TEST_THREADS=1` for integration tests.
 - Recommended: keep shared defaults in `.env`, copy overrides to `.env.local`, and rely on startup loading both files.

 - **Stations** – `GetStationById`, `GetStationByIdList`, `GetStationsByGroupId`, `GetStationsByCoordinates`, `GetStationsByLineId`, `GetStationsByName`, `GetStationsByLineGroupId`. `QueryInteractor` enriches stations with lines, companies, station numbers, and train types.
 - **Lines** – `GetLineById`, `GetLinesByIdList`, `GetLinesByName`. Results include company data and computed line symbols based on repository helpers.
 - **Routes** – `GetRoutes`, `GetRoutesMinimal`. The minimal variant returns `RouteMinimalResponse` with deduplicated `LineMinimal` data; paging tokens are currently empty (pagination not implemented).
-- **Train types** – `GetTrainTypesByStationId`, `GetRouteTypes`. Train types aggregate by line group and include related lines plus optional train type metadata. Rail variants use `TrainTypeKind::{Default, Branch, Rapid, Express, LimitedExpress, HighSpeedRapid, CommuterRapid}` (0-6); bus variants use `BusRoute` (7), which represents a `(route_id, shape_id)` operation pattern (e.g. 循環 / 短ターン / 支線) generated automatically from the Toei Bus GTFS feed.
-- **GTFS bus integration** – At startup, `src/import.rs::integrate_gtfs_to_stations()` ingests GTFS feeds into `gtfs_*` tables and then projects them onto the shared `stations` / `lines` / `types` / `station_station_types` tables. Every configured feed is imported, including Seibu Bus (downloaded from ODPT with `ODPT_ACCESS_TOKEN`). `transport_type` (0: rail, 1: bus) on both `stations` and `lines` keeps the two worlds queryable side by side. GTFS IDs are namespaced per feed before import to avoid cross-operator collisions. `line_cd` (100,000,000+), `station_cd` / `station_g_cd` (200,000,000+), and bus `type_cd` / `line_group_cd` (100,000,000+) are all deterministic fnv1a hashes that stay clear of the rail data ranges. Disable the entire bus pipeline with `DISABLE_BUS_FEATURE=true`.

Disable the entire bus pipeline with `DISABLE_BUS_FEATURE=true`.
 - **TTS metadata** – `Station`, `StationMinimal`, `Line`, and `TrainType` expose `name_ipa` / `name_roman_ipa` plus `name_tts_segments` for multi-segment pronunciation output. Use `name_tts_segments` when clients need per-token SSML construction for mixed-language names such as `Kasai-Rinkai Park`.
 - **Connected routes** – `GetConnectedRoutes`. `QueryInteractor::get_connected_stations` is not implemented yet and returns an empty vector; update the use-case and infrastructure layers together when adding real logic.
 - Changes to the service contract require coordinated updates to `proto/stationapi.proto`, regenerated code via `tonic-build`, and corresponding adjustments in both presentation and use-case layers.
