SK: the block code is not an id

 - ES-CL: the ITACyL server is https-only, the 2025 shapefiles sit in province subfolders, and C_REFREC is the identifier
 - A test refuses a fixture above 5 MB, committed or merely lying in the fixture folder, because a failing convert test downloads the real source there
 - ES-MD: find RECINTO.shp wherever the archive puts it
+- SK: KODKD is the LPIS block code (non-unique, sometimes empty), so it is kept as block_id and the row index identifies the field
 - EC-LT: nothing in the release identifies a parcel, so the row index does
 - ES-CM: read the year-named SIGPAC service, whose id field is OBJECTID_1, with the determination date from the variant
 - ES-CN: the seven island files each kept their own row index, and the region was declared as Cantabria
