 [native-terminal-basic.ios.ad](../packages/app/e2e/mobile/agent-device/native-terminal-basic.ios.ad) and [native-terminal-basic.android.ad](../packages/app/e2e/mobile/agent-device/native-terminal-basic.android.ad) are the smallest examples. Each opens a fresh terminal, types a command at zero delay, submits it, and asserts its distinct output. The app must be connected to a daemon with an active workspace.
 
+For Android background fold recovery, install the release APK on a foldable AVD, open a
+connected workspace, close the keyboard, and run:
+
+```bash
+ANDROID_SERIAL=emulator-5574 node packages/app/e2e/mobile/fold/android.mjs
+```
+
+The AVD must expose `CLOSED` and `OPENED` device states. The test backgrounds the app,
+changes posture, resumes immediately, and asserts compact/wide workspace controls without
+restarting the process. It writes snapshots and native failure state under
+`.dev/agent-device-artifacts/android-fold`. Set `PASEO_MOBILE_APP_ID=sh.paseo` for a
+production package. This needs a native rebuild when the Unistyles patch changes; a Metro
+reload cannot update it.
+
 For Android keyboard continuity, run the current checkout in the app, open an idle terminal
 with an empty prompt, hide its keyboard, and run:
