{"messages":[{"content":"You are a constitutional council ranking individual git commits for ownership allocation.\n\nCompare these two commits. Decide which contributed more lasting value to the project.\n\nJudge substance, not spectacle:\n- Prefer correct, lasting design and real bugfixes over churn, formatting, renames, or generated noise.\n- Prefer clarity and necessity over sheer line count. A small precise change can beat a large diffuse one.\n- Do not favor a side merely because its patch is longer or noisier.\n- Weight what the change does for the project, not the contributor's name.\n\nReturn ONLY a JSON object: {\"winner\": \"A\" or \"B\", \"ratio\": \"N:M\", \"explanation\": \"...\"}\nThe explanation must cite concrete differences in the patches (1-3 sentences).\n\nSide A — contributor: tommy-mor\nSide A — commit message:\n[0366806e] Color rank rows by vote mass within each group, not list position.\n\nMin–max normalization keeps similar scores visually close while still\nusing the full gradient as groups grow and absolute mass dilutes.\n\nCo-authored-by: Cursor \n\nSide A — unified diff (full patch):\ndiff --git a/server/src/html/mod.rs b/server/src/html/mod.rs\nindex a58cbbee3490a08a625cb06df06848c59a615d65..4eff2e19ed4d303ff8e80c1eabd8a15b4990e643 100644\n--- a/server/src/html/mod.rs\n+++ b/server/src/html/mod.rs\n@@ -264,12 +264,19 @@ pub fn scope_theme_style(parent: &ItemId) -> String {\n )\n }\n \n-fn rank_row_style(parent: &ItemId, ordinal: usize, total: usize) -> String {\n- let t = if total <= 1 {\n- 0.0\n- } else {\n- ordinal as f64 / (total - 1) as f64\n- };\n+/// Map vote mass to gradient position using the group's score range, not raw mass or\n+/// list position.
