Sources

The board that makes the whole service trustworthy: every upstream feed the Grid polls, reporting its own health out loud. For each source you get the poll interval, the last successful fetch, how close it is to going STALE, the staleness thresholds, and the last error verbatim — the honest-freshness contract, exposed. A feed that fails says so; absence of data is never shown as an all-clear. This whole page is one live fetch of /api/v1/sources — replay it yourself.
