+# Adversarial Bug Report: Artifact Badges on Task Cards
+
+## Deep Review
+ARTIFACT_LABELS mapping is static and matches COLUMNS. Badge rendering depends on review status, which is fetched from the API.
+
+## Potential Issues
+1. **XSS in artifact label**: ARTIFACT_LABELS values are hardcoded — no injection vector. Safe.
+
+## Verdict: PASS
