| Variable | Description | Default |
|---------------------------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|---------------------|
| `IDEMPOTENCY_TTL_SECONDS` | How long (in seconds) stored idempotency keys are kept before garbage collection. The offline client replays queued mutations with their `X-Idempotency-Key` on reconnect, so this must exceed the longest expected offline window or a replay could create a duplicate. Invalid values abort startup. | `2592000` (30 days) |
| `NOMINATIM_URL` | Custom HTTP(S) Nominatim base URL for maps and Atlas geocoding. Unset or blank uses the default. | `https://nominatim.openstreetmap.org` |
| `OVERPASS_URL` | Custom [Overpass API](https://wiki.openstreetmap.org/wiki/Overpass_API) endpoint(s) used by the map's POI "explore" search, comma-separated. When set it **replaces** the bundled public mirrors — point it at an internal or self-hosted Overpass instance when the public mirrors are unreachable from your network (e.g. firewalled/locked-down egress in a Kubernetes cluster). Entries that aren't valid `http(s)` URLs are ignored. If you don't run your own Overpass but the public mirrors throttle TREK, first make sure `APP_URL` (or `ALLOWED_ORIGINS`) is set: that alone gives outbound Overpass/Nominatim requests a unique User-Agent, which the public mirrors rate-limit far less. | bundled public mirrors |
| `OVERPASS_TIMEOUT_MS` | Per-endpoint timeout (in milliseconds) for Overpass POI requests. Endpoints race in parallel and one that hasn't answered within this window is abandoned so a faster mirror can win. Raise it if you run a slow self-hosted Overpass instance. Invalid values abort startup. | `12000` |
| `LLM_TIMEOUT_MS` | How long (in milliseconds) one AI-parsing call may take before it is abandoned. One ceiling for every provider, applied to the abort signal and to the underlying HTTP client alike. The default is generous so heavier parsing work fits without a code change; lower it if you use a cloud provider and would rather fail fast. Invalid values abort startup. | `900000` (15 min) |
