Real Codex execution of the returned AgentDevice launcher after recovery:
agent-device screenshot /tmp/pr-agent-device.png -> SESSION_NOT_FOUND before opening an app
agent-device open com.google.android.apps.nexuslauncher -> exit 1, Android unable to resolve DEFAULT/LAUNCHER intent (package is installed)
agent-device open com.android.settings -> exit 0, Opened: com.android.settings
agent-device screenshot /tmp/pr-agent-device.png -> exit 0, /tmp/pr-agent-device.png (1080x2400)
Screenshot independently inspected: actual Android Settings screen.
Unrelated launcher intent failure is not attributed to this PR.

Runtime limits: Linux local Android emulator only. Native T3 mobile clients, macOS/iOS, Windows, SSH/remote device hosts not exercised.
Recovery stop failure/timeout preservation covered by existing tests, not injected into the real CLI.
