Every failure class a question can carry. A closed vocabulary, because the
status route serves it to a reader of the derived scope: it never carries a
scope name, the question or provider detail.
inference_unavailable — the provider or relay failed. The only
transient class: the Personal Server retries it on its own.
source_missing — a source scope is deleted or holds no local data.
grant_invalid — the registering builder's grant no longer covers what
the question reads.
internal — anything else, including a permanent provider 4xx.
