+**Breaking Change:** AlertDialog API cancel button behavior changed
+
+The `cancel` button in AlertDialog now rejects the promise instead of resolving with `'cancel'` status, aligning it with the dismiss (Escape key) behavior.
+
+**Migration Guide:**
+
+**Before:**
+```typescript
+alertDialogAPI.open({...})
+  .then((status) => {
+    if (status === 'cancel') {
+      // Handle cancel
+    } else if (status === 'confirm') {
+      // Handle confirm
+    }
+  })
+```
+
+**After:**
+```typescript
+alertDialogAPI.open({...})
+  .then((status) => {
+    if (status === 'confirm') {
+      // Handle confirm
+    } else if (status === 'secondary') {
+      // Handle secondary action
+    }
+  })
+  .catch(() => {
+    // Handle cancel or dismiss
+  })
+```
+
+**Note:** `AlertDialogResolveStatus` type no longer includes `'cancel'` - it now only contains `'confirm' | 'secondary'`.
