Models

Nobody sells the history of this market. The gateways publish what is true today and replace it tomorrow, so the only way to have a series is to have been recording. This instrument records: one sweep a day, every model with traffic, every provider serving it, every price they ask.

Outside sources sit alongside that sweep — a second gateway that does publish its history, the public model hub where weights either are or are not, and a curated registry of notable models. Where they disagree, they are kept apart and the disagreement is the finding.
