openai/gpt-5.2-chat → A (3:1)

Commit A improves the production codebase by fixing workspace-wide clippy warnings, tightening patterns, simplifying code, adding a missing test annotation, introducing a type alias for readability, and cleaning up multiple modules and tests. These changes enhance code quality, maintainability, and CI hygiene across many files. Commit B adds planning and notes documents with substantial text, but no executable code or functional changes. While useful for future direction, it does not directly impact the running system. Therefore, Commit A contributes significantly more to the project.
