Real LVGMC FTP credentials arrived today; real DMI HARMONIE credentials haven't. The combined flag would have enabled both the moment FTP's were ready, crash-looping the app on HARMONIE's still- placeholder values via parMapN — caught this before it happened (the Grib job was ~15 min from its first scheduled run). Split into ENABLE_LVGMC_FTP_JOBS and ENABLE_HARMONIE_JOBS so each provider can be enabled independently as its own credentials become real.
Weather Tool
Tool for downloading historical and real-time data from weather stations in Latvia. It aggregates and displays data for different time periods, cities, and weather parameters.
Setup
Rename .env-sample to .env and fill in credentials
Environment boundary
- Windows: source editing, review, and Git operations only. Do not compile, build, run containers, install project dependencies, or test the application here.
- Rocky Linux: the only development runtime; compile, build, run, seed, and test WeatherTool here.
- Ubuntu VPS: deployment target only. It receives the reviewed release artifact built and verified on Rocky; it is not a development or build host.
