The seat verb try gains members (ADR 0637 section 6); the try's group name and the missing-preview reason are one definition of mesh-delivery-sdk (ADR 0637 section 8).

The checker says try.started (members at their commits) and try.ended for a whole try; the indexer writes and
deletes the candidate from them and finds the open tries again at its start through checker_tries, never reading
the checker's state. The try's digests are judged inside the one pass that takes the seats; the definitions of every
contracts module of each member are read; the config declarations leave a try's candidate alone.
