source_warnings indicates retained older data or failed or unknown source statuses. If the response shows publication=not_published the attempt was not published. A technically healthy service does not guarantee up-to-date source data.
Language and stable identifiers
Add lang=en to analytical API URLs for English labels, or lang=de for German. Requests without lang retain the existing German presentation. IDs, numerical values, reporting dates and status codes do not change. label_de remains German; label_en is English; label and the presentation fields follow lang.
