Package curation records who curates the Launchpad marketplace and what they decided about a collection: applications, feature slots, temporary holds, verification and appeals. It holds no coins and no tokens, never changes a collection's terms and never blocks a transfer, sale, refund or claim: a client reads these records and decides what to show.
ApplicationJSON returns null for a collection nobody applied for.
