What this does not say

Quoted verbatim from the section’s warnings field, exactly as the API returns it. They are not translated: a translation would show something other than what your response actually contains.

Describes an attempt to read this address from the live Matrikkel API, not the address. No record means no lookup was requested — usually because the cache already held the address. status=queued means nobody has asked the source yet; the buildings section being empty at that moment establishes nothing.
outcome='answered' with building_count=0 is the source stating there is no registered building at this address. A null building_count is the opposite: we do not know. outcome='authorization_rejected' means Matrikkel refused our credentials, which is a fact about us and says nothing whatsoever about the address. source_environment='test' marks an answer from prodtest, which is never written into the cache.

Fields

4 of 11 fields are value fields — the ones that decide whether a record actually says anything. The rest are context: identifiers, codes and timestamps.

Why it cannot be tried here

This section is not part of the public demo projection. That is a licensing and privacy decision, not a sign the data is missing: it is served to customers granted the section.
