actorkind describes the actor category and
does not identify the transaction purchaser.
A buyer_ref permits correlation within the intended Studio or guest
transaction scope. It exposes no global guardian ID or Clerk ID. Names and
email are available only through the separately permissioned
purchaser context endpoint. The universal event
ledger stays unchanged when an integration opts in.
The shipping topic has a narrow exception for known carrier, service level,
tracking number, and tracking URL facts. Other events do not acquire shipping
fields. Recipient and address details remain excluded.
A missing event capability prevents delivery of that topic. It does not turn
the frozen shared event into a different payload. Guardian connection topics
require their own explicit capability and privacy opt-in; that grant does not
authorize purchaser details.
