Every connection this city node holds.

Every connection this city node holds, in one list: live feeds (APIs), webhooks, file imports, and manual entries, each shown with the cells it feeds (the parts of city life the Index reads), when it last pulled data, and any error still open. The error column matters. An unresolved error here means a part of the matrix has no working source behind it. The list below is the v0 sample set. The endpoints are the real targets, but the connection states and pull times are illustrative.
