 | 2026-08-23 | `39fcb3e` | Remove the dead `METEO_*` fetch path (`fetch/csv/FetchService.scala`, its empty test, and its env vars everywhere) — confirmed via git history it's the same underlying LVĢMC data as the FTP/open-data paths, just an earlier, superseded delivery mechanism that was never wired into anything running | Yes — Scala tests (2 suites now, down from 3, the deleted one was empty); VPS deployment pending |
 | 2026-08-23 | `4036d24`–`4b92272` | Add `fetch.lvgmc.WaterTemperatureService`: real, free, keyless water temperatures for all 6 Ūdens zones (2 coastal `SEDUT` stations for Jūra/Līcis, 4 inland `WTEMD` stations for Kurzeme/Zemgale/Vidzeme/Latgale), fetch-on-demand with a 15-minute in-memory cache mirroring `WarningService` rather than the persisted station-observation path, since Ūdens has never stored history | Yes — Scala tests, Rocky rebuild, direct API curl confirming real values for all 6 zones; caught and fixed one station-selection error (Daugavpils only reports water level, not temperature — swapped for Ludza) via direct verification before committing; VPS deployment pending |
 | 2026-08-23 | `5a92465` | Auto-populate Ūdens's min/max fields from `/api/water-temperatures` on load, mirroring Faktiskā's fetch/override/reset pattern, with per-zone manual-override tracking and an "Atiestatīt" reset button | Yes — Rocky typecheck, build, and headless-browser verification (Playwright in Docker, since `chromium-cli` wasn't available in this environment) confirming auto-populated values match the API, manual edit correctly flips a zone to "Manuāli" and enables its reset button, and reset correctly restores the fetched value; noted along the way that `/udens-temperatura` 404s on a direct hit (no SPA fallback yet, consistent with the known limitation already listed) but works via client-side nav; VPS deployment pending |
+| 2026-08-23 | `9eca9eb` | Fix the one-station-per-zone design catching a real problem after deploy: every zone showed the same value duplicated as both min and max ("19...19"). Classified all 65 LVĢMC stations that report water temperature (56 inland WTEMD, 9 coastal SEDUT) into the 6 zones by geography and report the real min/max across each zone's currently-reporting stations, dropping readings over 12h stale so one stuck sensor can't skew a range | Yes — Scala tests, Rocky rebuild, direct API curl confirming a genuine spread per zone (e.g. Vidzeme 11.4–18.7°C, traced the low point to a real fresh reading from a colder headwater station near Cēsis, not a stale-sensor artifact), and headless-browser screenshot confirming the UI renders the real spread (e.g. "11...19") with no console errors; VPS deployment pending |
