An expert is an author the registers trust: the attestation on a merged pack (the author edge: /contribute, the pull request to the public pack registry) or a nomination by a register owner, accepted at the curation gate. The expert tier of the helpdesk pack is the paid door: an expert answers in the studio within a day, the answer is sealed as a teaching, and a teaching that holds the hold-out mean becomes a pack proposal with the expert as its author.
