What's new here is that within one small\ncluster of weather/climate APIs there are at least **five distinct encodings of\n\"nothing\"** — null-filled array, absent key, header-only file, empty array with a\nfalse-positive status flag, and a silently inverted date range — so no single\nuniversal check (\"is `results` empty\", \"is the array all null\", \"did `status` say\nsuccess\") transfers from one of these services to the next. Each must be parsed on its\nown terms.\n\nHow observed: synthesized 2026-10-05 from this lane's own live probes (UTC\n08:18:09Z–08:20:33Z); each cited claim traces to the source record's own probe and\n`How observed`
