Drift by provider
The same model, served by every provider, on one timeline. Each strip is that provider's drift from its own reference period; dots mark detected changes, placed at the drift level they reached. A model version is nominally fixed — so a change here is the provider's serving stack moving, and it should stand out against providers that stay flat. Shared y-scale within each method, so strip heights are comparable.
