NATS — verae-zapier-simulator

The simulator does not subscribe to live NATS. It replays the same addresses in-process so a trace console can validate messaging before the Zapier app is pushed.

Simulated address	Publisher (in trace)	Subscriber (in trace)
HTTPS Zapier → zappier-edge → middleware	zapier-platform-app	zappier-edge
verae.zapier.jobs.watch	middleware-http	job-poller
verae.zapier.jobs.events	job-poller	middleware wait, webhook-deliver
verae.zapier.webhooks.deliver	middleware	webhook-deliver → HTTPS Zapier hook
verae.archive.put	splitter / merkle builder	archive-* / tree-node-*
verae.archive.query	archive-aggregator (broadcast)	every WORM and tree node
verae.archive.reply.<id>	node on bloom hit only	aggregator

Live NATS stays on NS1 loopback. Do not point this UI at a public NATS URL.
