What
The function that determines the active authentication type now returns both the auth type and whether the API key came from an apiKeyHelper, and treats a key sourced this way as present even if its actual value is empty or falsy.
A new api_key_helper case was added to the logic that decides model-catalog access policy, so it now goes through the same allow_model_catalog policy check that was previously only applied to not_claude_ai_auth. The no-auth-method case also gained API-key-specific served-catalog handling.
Why
This ensures that when an organization supplies API keys via an apiKeyHelper script rather than a static key, Claude Code correctly recognizes that an API key is in use and applies the same model-catalog access policy as it does for other authentication methods.
