Use case
Activity and event feeds
Audit trails, order flows and incident timelines are one shape: an append-only list somebody is watching. Loaded over HTTP, kept current by events.

How it works
- 01Load, then subscribeFetch the page over HTTP, then subscribe — in that order, so nothing falls in the gap.
- 02Append on publishNew entries carry the same shape as the HTTP payload, so one renderer handles both.
- 03Scope by channelOne channel per account keeps authorisation simple — the subscription is the check.
Worth knowing
A client that reconnects has a gap. Re-fetch the head of the feed rather than assuming the socket caught everything.
