+Platform constraints that affect automation behavior.
+
+## iOS: "Allow Paste" dialog suppressed under XCUITest
+
+iOS 16+ shows an "Allow Paste" system prompt when an app reads `UIPasteboard.general` in the foreground. When an app is launched or activated through the XCUITest runner (which `agent-device` uses for iOS), the iOS runtime detects the testing context and silently grants pasteboard access — the prompt never appears.
+
+This is an Apple platform constraint that affects all XCUITest-based automation tools.
+
+**Workarounds:**
+
+- **Pre-fill the pasteboard via simctl** — set clipboard content without triggering the dialog:
+  ```bash
+  echo "some text" | xcrun simctl pbcopy booted
+  ```
+- **Test the dialog manually** — the "Allow Paste" UX cannot be exercised through XCUITest-based automation.
