Revision
Cache check
The revision moves when the upstream changes. Clients compare it with the copy they stored.
The public page names the upstream, the revision, and whether the feed is live. Quote rows stay on the trading side.
Feed card
GET /api/sourceGET /api/source is the feed card for this host. It names the upstream being quoted, the revision a client last saw, and whether that feed is live. The route does not return quote rows. On Bram House that source id is src_318b2ed8.

Upstream
Each host quotes one upstream. The card is how a client learns which one.
Status
A paused feed stays on the card so a client can tell a quiet market from a stopped source.
