What's Wrong or Missing?

The documentation does not make it clear whether or not Claude Code proxies any data through Anthropic when configured with a third party model provider such as Google Vertex.

I'm guessing a lot of enterprises require specific documentation clearly stating that nothing is being proxied by a tool even when configured to use otherwise approved model providers to avoid obvious privacy concerns.

Suggested Improvement

The documentation should state clearly whether or not Claude Code sends any traffic back to Anthropic when configured to use a model other than any of the Anthropic-provided ones.
