## [Unreleased]

### Fixed
- **Critical Bug:** Corrected the MiniMax API call in `opus_orchestrator/utils/llm.py`. The `system` prompt is now correctly passed as a top-level field, resolving the issue where the model would ignore instructions and respond in Chinese.
- **Language Consistency:** Added a universal and explicit instruction to all agent system prompts (`BaseAgent`, `PydanticAI`, `AutoGen`) to respond ONLY in English. This provides multiple layers of defense against language drift.
- **AutoGen Revision Loop:** Fixed the chapter iteration logic in `opus_orchestrator/autogen_critique.py`. The `Writer` agent is now correctly prompted to revise the chapter text, and the `iterate_chapter` function properly extracts and applies the revised content.

### Added
- `CODE_REVIEW.md`: A detailed document outlining the findings from the code review, including the root cause analysis of the language drift issue.
- `CHANGELOG.md`: This file, to track changes to the project.
