- Start: WinSW's NetX.out.log/err.log in data\runtime are the same files as start_netx.ps1's netx.out.log (case-insensitive) and stay open, so NetX could not truncate its log and every start failed. WinSW logs now go to data\runtime\service. - Stop: nothing told the service_run.ps1 supervisor to exit, so it kept restarting NetX and WinSW waited forever. stop_netx_app.ps1 writes the service.stop flag (-KeepSupervisor for the supervisor's own restarts), service_run checks it every second, and runtime_ctl / service_lifecycle write it before stopping the service. - WinSW launched powershell.exe as stop hook never reached the script (stuck on inherited std handles); run it via cmd with NUL stdin and output to data\runtime\service\stopexec.log. stop_netx_app.ps1 keeps a timestamped trace there. Offline Windows Sandbox: service install -> healthy in 28s, stop in 20s. Existing service installs need "install service" re-run to pick this up.
