+# Adversarial Bug Report: Inline Comment Textarea for Review
+
+## Deep Review
+Textarea value is read with `.value`, sent as JSON, and stored directly in REVIEW.md.
+
+## Potential Issues
+1. **No input sanitization**: Comment text is stored raw. If REVIEW.md is later parsed by markdown renderer, injection possible. Acceptable risk — REVIEW.md is a structured data file, not a rendered document.
+
+## Verdict: PASS
