This seal is live. Wherever it is placed, it reads the record each time it is shown, says exactly what this receipt says, and links back to this page. When the record changes, the seal changes with it. Nobody can buy it and it costs nothing: it is the same instrument for every business on the record.

Today it reads NOT YET CHECKED · ON THE RECORD · 0 OF 3 FACTS VERIFIED. When the register check verifies this business, the same address starts reading VERIFIED, with no change to the embed.

What assistants named this edition

Probe battery input, never a score. The same questions, the same edition, who was named.

ChatGPT · never Gemini Perplexity

Named by a subset of assistants. Only Gemini and Perplexity name them this edition; ChatGPT never does. If either changes its mind, the other still names them — or does not. That is an input on the receipt, not a score.
