list_models requires the client to advertise a modelCatalog capability.

What

A new control message, list_models, lets a client running against a remote worker fetch the list of selectable models rather than computing one locally, because the worker's provider and settings decide what is available. It is gated on the client advertising a modelCatalog capability.

Details
  • Only reachable in remote thin-client sessions; a normal local session picks models the usual way.
Evidence

Requests the worker's selectable model catalog.

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
