A payload that runs the Tailscale client (tsnet, userspace networking) on a jailbroken PS5: a C launcher built with ps5-payload-sdk that loads a Go program in-process, an installer that registers it with the console's payload autoloader and adds a home screen icon, and the patch that makes Go 1.27.1 speak the PS5's FreeBSD 9 era syscall interface.
