+# Cloudflare DNS Mirror Notes
+
+This skill treats Cloudflare as a **mirror**, not the source of truth.
+
+## Mirror Records File
+Create: outputs/mirror_records.json
+
+Example:
+[
+  {"type":"A","name":"app","content":"1.2.3.4","ttl":120},
+  {"type":"CNAME","name":"git","content":"app.example.com","ttl":120}
+]
+
+## Rollback
+When mirroring, record IDs are saved in outputs/cloudflare_record_ids.txt.
+undo_cloudflare.sh will delete those IDs (best effort).
