Verification console

Every line below is read live. Nothing here is remembered from a document, and nothing is reported as proved that this page did not just observe. An endpoint that is not deployed reads as not deployed, which is a fact rather than a failure.

Configuration, read as text

The backend, read by GET

Each of these is a health line. A build stamp on it answers which deployment is live by a GET rather than by a table somebody has to remember to update.

What this page will not tell you

Whether a row STORED. Only a count per table says that, read a couple of minutes after the send, and read per table rather than in aggregate.
Whether a message was DELIVERED. An outcome code reports acceptance.
Whether a segment matched. That number moves in the panel, which is the point.
