openai/gpt-5.2-chat → B (1:25)

Commit B introduces a substantial new feature (pairwise vote compare UI), adds multiple new modules (pair.rs, vote.rs), extends existing core types (ItemId normalization), updates reducers, API handlers, JS/CSS, and includes both unit and integration tests. It meaningfully expands functionality and refactors behavior across the stack. Commit A only removes a single test function, a minimal change with negligible impact. Therefore, B contributes far more overall.
