What probably matters to youSection of the release

A model-capability fetch is written and saved to disk, but a guard stops the network call entirely in this build.

What

A new routine asks the API for the list of models, records a capability entry for each and saves them. Two guard checks run before any network call and one of them short-circuits it entirely in this build, so no fetch happens. Failures log a single line.

Details
  • The request can optionally carry a beta header.
  • The failure line is prefixed [modelCapabilities] fetch failed: .
Evidence

[modelCapabilities] fetch failed:

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