  note: Rewritten into hosts[] -> documents[], the only shape well_known_docs() in score.rb reads. A served
    .well-known surface recorded in any other shape scores as absent. Promoted ONLY the 2xx rows out of
    the probe log; non-2xx probes are real negative results and were left in place, not converted into
    documents.
