+## Important Notes
+
+- ✅ Edit preserves vector if only metadata changes
+- ✅ Edit re-embeds if content changes
+- ✅ Create generates proper embeddings automatically
+- ✅ Search is case-insensitive
+- ✅ User ID is optional (for user-specific facts)
+- ⚠️ Deleting is permanent (no undo)
+- ⚠️ Container must restart after API changes
