Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🟡 Moderate · up to Configured remote devices are not connected automatically at startup, so the advertised workflow may remain unavailable until an extra RPC is made; unreachable devices can also cause connection operations to hang and failures lose useful ADB diagnostics. These bounded correctness and reliability issues should be addressed before merging. Suggested reviewers: Sequence Diagram(s)sequenceDiagram

Add a timeout for ADB connection commands.
subprocess.run has no timeout and can block exporter initialization or connect_device/disconnect_device if adb hangs. Add a finite timeout to the ADB commands around Lines 116-123 and 141-148, handle subprocess.TimeoutExpired, and add coverage for the timeout path in driver_test.py.

Clear side_effect before setting return_value.
reset_mock() does not clear side_effect, so the call for 10.0.0.2:6520 uses the remaining 10.0.0.1:6520 response instead of the response configured on the next line. Clear side_effect before assigning return_value, and assert the exact stripped response for the new address.

Implement the required startup auto-connect.
AdbServer.__post_init__ starts the ADB server but never calls _connect_device. The new method is only reachable through an explicit RPC call. The initialization test also requires exactly two subprocess calls. A configured remote device will not connect at startup.

Preserve ADB diagnostics when a command fails.
Both handlers capture stdout and stderr, but str(e) omits them. Return the captured diagnostics, with str(e) as a fallback, and add regression coverage. Apply the same pattern to disconnect_device.
