Live & Realtime
Server-calling surfaces for automation: SSE stream, long-poll, background jobs, a webhook receiver, plus dynamic autocomplete & cascade backends.
Server-Sent Events
Emits 10 ticks then an event: done.
Long-poll
Each call holds ~1s then returns the next event; cursor advances to 10.
Background job
POST returns 202 + id; polling drives the bar from running → done (~3.0s).
Webhook receiver
POST arbitrary JSON → 202; payload is stored to the audit log.
