- Introduced `xaiChatBaseURL` helper to normalize base URLs for non-media chat requests.
- Added `applyXAIChatHeaders` to handle CLI chat-proxy-specific headers.
- Updated logic to differentiate between default, chat-proxy, and custom gateway base URLs.
- Extended test coverage to validate behavior of headers and base URL handling across scenarios.
Closes: #4182
- Refined tool normalization logic to pass namespace context (`namespaceName`) to `normalizeXAITool`.
- Limited schema simplification to `codex_app.automation_update` to avoid unintended modifications to unrelated tools or namespaces.
- Updated `xaiFunctionParametersNeedSimplification` to match tools by exact namespace and name.
- Enhanced tests to validate correct schema simplification for `codex_app.automation_update` while preserving unrelated tool definitions.
Add Grok-native reasoning replay for Claude-sourced xAI Responses requests. Replay state is scoped by model and session, normalized to reasoning/function_call/custom_tool_call items, and injected with the same tool-call alignment semantics used by Codex.
Include the minimal Grok encrypted_content validator needed on upstream/dev so replay cache entries cannot accept Codex/GPT, Gemini, or Claude signature shapes. Cache completed output items from HTTP, streaming, and WebSocket xAI responses.
Cover two-turn Claude replay, tool_result continuity, valid Grok cache storage, and rejection of Codex-shaped encrypted_content.
- Introduced `xaiNormalizeReasoningSummaryData` and related functions to normalize `reasoning_text` events into `reasoning_summary` shapes for standardization.
- Updated WebSocket and streaming logic to process normalized reasoning summary events correctly.
- Enhanced tests to validate normalization, order of events, and output structure in both stream and non-stream scenarios.
- Added methods for managing and tracking WebSocket transcript state, including recording, prepending, and replacing transcript inputs.
- Implemented `executeCompactionTriggerFromWebsocketContext` to support compaction triggers using recorded transcript context.
- Enhanced upstream-downstream ID mapping with additional utilities and state synchronization.
- Expanded test coverage to validate transcript state management, compaction payload generation, and WebSocket response handling.
- Developed `XAIWebsocketsExecutor` for handling xAI Responses via WebSocket transport.
- Introduced session and state management with `codexWebsocketSessionStore` and `xaiWebsocketIDStateStore`.
- Added robust ID mapping for upstream and downstream request/response sequences.
- Enhanced error propagation and handling of WebSocket terminal events.
- Included utility methods for WebSocket request preparation, connection management, and state tracking.
- Added foundational support for compact and streamed responses via enhanced session tracking.
