Summary of Changes

Hello, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request implements a model mapping mechanism to allow for flexible redirection of AI model requests. By introducing a new decorator pattern for content generators, the system can now intercept and transform model identifiers before they reach the underlying API client. This change ensures that specific authentication flows can route requests to the appropriate model versions as required by the updated configuration.

Highlights

• Model Mapping Implementation: Introduced ModelMappingContentGenerator to dynamically map AI model identifiers based on defined configurations.
• Configuration Updates: Updated default Gemini flash model settings to gemini-3.5-flash and added CCPA_AI_MODEL_MAPPINGS to manage model routing.
• Code Assist Integration: Updated getCodeAssistServer to recursively unwrap ModelMappingContentGenerator and LoggingContentGenerator wrappers.
• Content Generator Refactoring: Integrated ModelMappingContentGenerator into the createContentGenerator flow to apply mappings for specific authentication types.

Code Review

This pull request introduces the ModelMappingContentGenerator class to dynamically map model identifiers based on the authentication type, specifically mapping gemini-3.5-flash to gemini-3-flash for Google Login and Compute ADC. It also updates getCodeAssistServer to recursively unwrap both logging and model mapping generators, updates flash model configurations, and adds comprehensive unit tests. No review comments were provided, so there is no feedback to address.
