 - Recommended: keep shared defaults in `.env`, copy overrides to `.env.local`, and rely on startup loading both files.

 ## Data Management
 - CSV import order depends on the numeric prefix (`1!`, `2!`, ...). When adding datasets, choose a prefix that preserves foreign-key dependencies.
 - `data/create_table.sql` drops and recreates tables, indexes, and foreign keys. Update this script alongside any schema or CSV column changes.
-- `data_validator` currently verifies that `5!station_station_types.csv` references valid station and type IDs. Extend the validator when new cross-references are introduced and keep the process fail-fast (panic on invalid data).
+- `data_validator` currently verifies that `5!station_station_types.csv` references valid station and type IDs, and that order-sensitive station sequences in `3!stations.csv` stay intact under `ORDER BY e_sort, station_cd` (e.g. the Toei Oedo Line's Tochomae rows, whose misordering silently drops the station from ETA estimation). Extend the validator when new cross-references or order-sensitive spots are introduced and keep the process fail-fast (panic on invalid data).
 
 ## Testing and Quality
 - **Unit tests** – `cargo test --lib --package stationapi` or `make test-unit`; focus on entities and repository mocks without a database.

 - **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. By default only the stable Toei Bus feed is imported; set `ENABLE_EXPERIMENTAL_BUS_FEATURE=true` to import every configured feed, 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`.

 - **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.
