+## Reusable Multi-Pair Dialog
+
+```
+Tags, Aliases, and Triggers all share a reusable multi-pair dialog for adding multiple
+key-value pairs at once.
+
+Dialog layout (dialog_add_multi_pair.xml):
+- ScrollView containing a vertical LinearLayout (rows_container) for dynamic rows
+- "+ ADD ROW" button below the scroll area (borderless, primary color text)
+
+Row layout (item_dialog_pair_row.xml):
+- Horizontal LinearLayout with:
+  - Key EditText (weight 1, empty hint for Appium)
+  - Value EditText (weight 1, empty hint for Appium)
+  - Remove row ImageButton (hidden when only one row exists)
+
+Behavior:
+- Dialog opens with one empty key-value row
+- "+ ADD ROW" adds another row to the container
+- Remove button uses ic_close drawable with colorPrimary tint (same as list item remove buttons)
+- Remove button appears on all rows when more than one row exists
+- Remove button is hidden when only one row remains (cannot remove the last row)
+- ADD button is disabled until ALL key and value fields in every row are filled (both required)
+- Validation runs on every text change and after row add/remove
+- On "ADD" press, all rows are collected and submitted as a batch
+- Batch operations use SDK bulk APIs (addAliases, addTags, addTriggers)
+
+Used by:
+- ADD ALIASES button (Aliases section) → calls viewModel.addAliases(pairs)
+- ADD TAGS button (Tags section) → calls viewModel.addTags(pairs)
+- ADD TRIGGERS button (Triggers section) → calls viewModel.addTriggers(pairs)
