+### CI‑generated graph
+
+This repository includes a workflow that scans git history to count the number of non‑comment lines in `banned.txt` at each change and generates:
+
+- A CSV at `metrics/banlist_counts.csv`
+- A chart at `assets/banlist_history.svg` (embedded above)
+
+The workflow runs on pushes to `main` that modify `banned.txt` and nightly on a schedule. Commits from the workflow are marked with `[skip ci]` to avoid loops.
