+## Trends Dashboard
+
+Each nightly run is posted as a GitHub issue labeled `vibe-test`, with a scoreboard
+table in the body. `trends-collect` reads every such issue, parses the scoreboard
+across the historical table layouts, and writes a normalized `trends.json`.
+`trends-report` injects that data into a single self-contained HTML dashboard —
+overall-score trend, Astryx-vs-Baseline gap with a moving average, per-dimension
+small multiples, and a sortable table linking back to each issue. No build step,
+no external chart deps (inline SVG).
+
+```bash
+# One shot: refresh data + rebuild the dashboard
+pnpm -F @astryxdesign/lns trends              # → trends-dashboard.html
+
+# Or run the stages separately
+pnpm -F @astryxdesign/lns trends:collect      # → trends.json
+pnpm -F @astryxdesign/lns trends:report       # trends.json → trends-dashboard.html
+
+# Point at a different repo/label
+pnpm -F @astryxdesign/lns trends -- --repo facebook/astryx --label vibe-test
+```
+
+Both `trends.json` and `trends-dashboard.html` are generated (gitignored). Runs that
+carry the label but aren't score reports — experiments, audits, failed runs — are
+excluded automatically; runs scored on the old 0–10 rubric are rescaled to 0–100 so
+the trend line stays consistent.
+
 ## Known Accepted Asymmetries
 
 These are intentional and documented; they slightly favor baseline, making Astryx wins more credible:
