Signup registers/binds a Verae central user and stores veraeUserId. Public access stays the zappier API key. Chain JWTs stay server-side behind tokenRef. Authz, billing, and jobs.watch carry veraeUserId.
In-process trace console validates hops, faults, recoveries, and
suggested changes before zapier-platform push. User guide covers
signup through central-chain and bulk-summary tree-node hash lookup.
