1 monitored endpoint (0 actively tracked, 1 no longer) across 1 provider, monitored 2025-06-26 – 2025-10-21. 1 of them shows at least one detected change (1 changes total). All 1 catalog endpoints by status: 1 retired.

## Drift by provider

The same model, served by every provider. A model version is nominally fixed — so a change here is the provider's serving stack moving. Each endpoint's full drift series (LT `drift`, B3IT `tv`) and detected changes are in the JSON above.
