Slovenia coverage is live at 4 km

Soča Valley, Tolmin, Lijak, Kobarid, Kobala, Vogel, Stol, Krvavec - the Slovenian soaring map at 4 km, four cycles a day, every field as JSON.

Tolmin is one of those places where, on the right week in July, every pilot you meet in the campsite is from a different country. The Soča Valley pulls thousands of pilot-days a summer from across Europe and well beyond, and most of those pilots have been making do with a global model averaged over a 13 km grid cell that completely fails to see the convergence between the Julian Alps and the Adriatic that makes the place fly the way it does.

As of today, Slovenia is on the Convek API at 4 km. Tolmin, Lijak, Kobarid, Kobala, Kovk, Vogel, Stol, Krvavec, and every coordinate across the Soča Valley, the Julian Alps, the Karavanke, and the Kamnik-Savinja Alps. Same fields as the UK and Switzerland, four cycles a day, all as JSON.

The country is small enough that running it is cheap. End-to-end about 9 minutes per cycle, by far the smallest country in the European batch. That is partly why it ships second: the compute is so trivial that there was no reason to wait, and it lets the worker prove out the multi-country scheduling rhythm before the bigger Austria and Spain cycles land.

Every field that exists for Switzerland exists for Slovenia, and the one worth highlighting is the day rating. The internal score that produces `poor` / `marginal` / `fair` / `good` / `excellent` is the same scoring function across every country Convek covers, so 'good over Tolmin' and 'good over the Long Mynd' mean the same thing meteorologically - even though one might be a 3000 m base day and the other a 1500 ft one. That consistency is the whole point of having a single API rather than five regional sites with five different colour scales.

Corridor sampling in time-aware mode is genuinely useful in the Soča. A long valley XC down to the Adriatic can take six hours to fly, and the forecast that matters is not the one at the launch waypoint but the one that walks ahead of you through time. `/v1/corridor` does that without you having to stitch dozens of point requests together.

The domain rectangle runs 12.7 E to 17.3 E and 44.9 N to 47.4 N, buffered into Italy, Austria and Croatia so the outer-cell GFS contamination sits outside the actual flying areas. Day-window and sounding labels use `Europe/Ljubljana` - the kind of detail that is invisible when right and grating when wrong.

Cadence is the standard four cycles a day at 00z / 06z / 12z / 18z UTC, 49 hour horizon, hourly. The 06z forecast lands well before mid-morning local time, in time for the Tolmin breakfast briefing.

Austria follows next week. Then Czechia. Same launch gate each time: a benchmark cycle, a manual check against known sites, eight clean scheduled cycles in a row, then the announcement. No country goes live just because the rectangle exists.

Free tier is 25 queries a day, no card. `region=si` plus any `lat` / `lon` in the box to `/v1/site` and you have a forecast. The Slovenia coverage page has the full coordinate box and field list, and the API docs have everything else. If you fly the Soča, guide there, or build pilot tools that need a real Slovenian feed, plug it in.
