- Added support for preserving native response.compaction payloads when compact serialization is requested in `serializeResponsesFinalPayload`.
- Implemented serialization of compact mode as `response.compaction` instead of an ordinary response object.
- Introduced a new type `ResponsesFinalSerializationMode` to manage serialization modes.
- Refactored `serializeResponsesFinalPayload` to handle different serialization modes and usage payloads.
- Added tests to ensure correct behavior for compact serialization and preservation of upstream payloads.
- Updated favicon assets and documentation configuration for VitePress.
- Added `routeCompatibility.ts` to handle response compatibility for different endpoints.
- Introduced `chatEndpointStrategy.ts` to manage chat endpoint recovery and downgrading logic.
- Created tests for chat formats and input file handling in `chatFormatsCore.test.ts` and `inputFile.test.ts`.
- Developed `endpointCompatibility.ts` to define compatibility checks and header building for various endpoints.
- Implemented protocol lifecycle management in `protocolLifecycle.ts` and corresponding tests in `protocolModel.test.ts`.
- Enhanced tooltip functionality with a new `TooltipLayer` component and associated tests.
- Refactored existing components to improve tooltip handling and ensure proper rendering in the application.
- Updated modelTesterSession tests to serialize assistant history as output_text and removed mime_type from input_file.
- Introduced new tests for stats proxy logs routes, covering paginated log retrieval and detailed log views with parsed billing details.
- Added server-driven tests for ProxyLogs component to validate API interactions and UI rendering based on server data.
- Updated chat stream tests to clarify reasoning behavior and ensure correct handling of include lists.
- Enhanced responses proxy route to normalize include lists and apply default reasoning includes based on request context.
- Improved transformer metadata handling, ensuring proper serialization and deserialization of metadata records.
- Added tests for preserving reasoning signatures and managing citations in OpenAI-compatible responses.
- Refined the logic for injecting default includes in responses and ensured compatibility with codex surface defaults.
- Added `inputFiles.ts` for handling input file resolution, including validation and normalization of file types.
- Introduced `proxyFileStore.ts` for managing file storage, retrieval, and deletion with owner-based isolation.
- Created tests for proxy file storage functionality in `proxyFileStore.test.ts`.
- Developed `proxyInputFileResolver.ts` to resolve input files in OpenAI and response formats.
- Added utility functions for handling reasoning signatures in `reasoningTransport.ts` and corresponding tests.
- Enhanced shared input file transformers in `inputFile.ts` for better file handling and type inference.
