Unclear What permissionContext and querySource actually affect in the client's behavior is not described in this finding.
What
The internal function that builds the Anthropic API client, handling headers, authentication, and provider routing for Bedrock, Vertex, Foundry, gateway, and similar setups, now accepts a new querySource parameter, which defaults to the existing source value, and a new permissionContext parameter. Some existing fields were also renamed to agentContext, credentials, and storageV5.
Why
This finding shows the API client builder gaining new inputs but does not describe what they change in the client's behavior.
