Persist account-balance books; edge caches prepaid from books. Add zappier-identity, verae-nats-accounts, verae-jobs-events, verae-access-staff, zapier-decisions. Edge binds loopback; lan-134 stays off; HTTP services prefer local spawn.
Unify loopback ops, hop testing, and reading order. Overview lists high-level docs first, then architecture, then the rest. Credits: Scott Lindsey, George Lambert, NATS.IO, Grok-Code by Grok.com.
