note: Claiming and shipping are counted separately, and neither is inferred. Publishers were found by
  fetching /.well-known/ai-catalog.json on every absolute host advertised in the catalog plus each host's
  derived apex; registries were exercised over their own documented endpoints. A manifest cannot be derived
  on a publisher's behalf — it is served from their domain or it does not exist.
