openai/gpt-5.3-chat → A (3:1)

Commit A bootstraps a substantial portion of the project: core parser architecture (~1800 lines), ranking algorithms, reducer state management, UI actions, frontend JS plumbing, and extensive tests. It establishes foundational systems across multiple layers (backend logic, UI interaction, testing). Commit B introduces a sophisticated and well-engineered git discovery and attribution system with strong testing, but it is a focused feature within an existing system. While complex and impactful, it is narrower in scope compared to the broad foundational groundwork laid in A.
