+## Leaderboard Progress Chart
+
+- Data source: `assets/leaderboard_history.json` (add new entry when models are confirmed)
+- Script: `scripts/gen_leaderboard_chart.py` (generates `assets/leaderboard_progress.svg`)
+- GitHub Action: `.github/workflows/leaderboard-chart.yml` — auto-runs when history JSON changes
+- Chart is embedded in README below the leaderboard table
+- Run locally: `uv run scripts/gen_leaderboard_chart.py`
+
+### When adding a new ISC case
+
+1. Update leaderboard table in README (🟢 → 🔴, add Demo + By)
+2. Update count "**X / 40 confirmed**"
+3. Add entry to Leaderboard History `<details>` section
+4. Add entry to `assets/leaderboard_history.json`
+5. Commit with `closes #N` to auto-close the issue
+6. Reply on the issue with verification + thanks
+7. Label: `verified`, optionally `novel-template`
+
+## Issue Workflow
+
+```bash
+# Reply and close
+gh issue comment N --body "Verified ✅ Added to leaderboard. Thanks @user!"
+gh issue close N --reason completed
+
+# Labels
+gh issue edit N --add-label "verified,novel-template"
+```
+
 ## Style
 
 - README headings: left-aligned with emoji icons (not centered, not numbered)
 - Navigation bar order: Paper → Leaderboard → Tutorial → ISC-Agent → ISC-Bench
+- Section name: "ISC-Bench" (not "ISC Quick Test")
+- Template links in table: `[📄](templates/...)` (not arrows)
 - Star History chart: add `&v=TIMESTAMP` parameter to bust CDN cache when needed
-- fig1_bench_overview goes in Quick Test section, not under authors
+- fig1_bench_overview goes in ISC-Bench section, not under authors
