This example is the whole of TicketOps Live in one page — the status strip, the background import monitor, the live ticket board fed by the global TicketHub, the cadence controls, the session diagnostics — plus what this module adds: the real-time health panel, the effective configuration and the production checklist.

What to try

Action	What you should see
▶ Start heartbeat	the clock and load bar move once per second with no click
Start Import / Cancel Import / Fail at 87	progress every 10 records while the heartbeat keeps running; a cancelled and a failed run both re-enable Start
Publish Event / New ticket events (10) / Escalate selected	the rows and notifications appear in every session of the same tenant; escalation also pops a toast
Tenant / Escalated only	this session's board changes; other sessions are unaffected
Unsubscribe / Subscribe	this session stops (and resumes) receiving hub events
Live mode, Cadence	events received grow faster than updates applied; the cadence changes the tick rate
Counter +1 / Background update	a per-session counter; a pushed log line 1.5 s later with no click
Health · config	Push expected / Polling off, active subscriptions, measured updates/min, the effective Default.json and HealthCheck.json, the ten-point checklist

Polling fallback. Add "enableWebSocket": false to Default.json and restart: connectionLabel shows No WebSocket, the Health tab reads Fallback mode / Polling enabled while work runs, and pushes arrive on the polls.
