airport-express-tools: rebuilding AirPort Express configuration and Wi-Fi client mode

airport-express-tools reconstructs configuration and Wi-Fi client functions for the second-generation AirPort Express A1392 from firmware and ACP protocol research. Its Python CLI configures Wi-Fi, connection sharing and device settings; a local web UI provides Wi-Fi and device controls. A replacement supplicant joins WPA2 networks. Reference pages map ACP properties, RPCs, firmware contents and client-mode behavior, with Ghidra and unpacking helpers.

How evidence classes are assigned

Requirements & limits

Prerequisites: The CLI requires Python 3.8 or newer; installing the replacement Wi-Fi client requires the device's debug SSH login.
Scope: A1392 on firmware 7.8.1 is the documented fully tested model; other models have limited or untested write support.
Limits: The firmware's own wpa_supplicant crashes in client mode on 7.8.1; the replacement supports WPA2-PSK on 2.4 GHz.
