PPLR renamed the aCountry fields upstream (GENCalpha3 -> GENCAlpha3, CtryNm -> Name,
ctryNmDisp -> DisplayName, ISOalpha2 -> ISOAlpha2). The query asked for the old
names, ArcGIS answered HTTP 200 with { error }, and the loop read that as "no
features". Every view that draws country polygons silently lost them. The
query now asks for the new names and gives each feature the old ones back, and an
{ error } body throws.
Paging also stopped after one page: f=geojson carries exceededTransferLimit under
data.properties, so only 200 of 251 countries loaded. A full page now means ask
for more.
Coverage: the status no longer claims a 6,000-row sample, and a __pplrCoverage()
handle reports how many polygons matched a coverage row.
