The console-window class (the project lead, 5 October 2026: "Windows Command Processor" windows on PC 1 whenever a remote job runs).
Measured on PC 1 (ae432dc7, Windows 11 Pro 26200, default terminal "Let Windows decide" = Windows Terminal 1.24) with
tools/windows/console-watch.ps1 (job run-20261005-182528): no child a job script starts from the app's headless
console opens a window (powershell, cmd, query, curl, nvidia-smi, wsl --status, a distro, interop cmd and powershell,
powershell -WindowStyle Hidden: 0 windows each); Start-Process in a new console opens a Terminal window (the known-failed
case: 2 windows), the same with -WindowStyle Hidden opens none (the known-finished case). The elevated path
(Start-Process -Verb RunAs -WindowStyle Hidden through the AppInfo service) is the one road left; its watcher
(console-watch-elevated.ps1, job run-20261005-184610) was cancelled at the UAC prompt.
- platform.rs: elevated_ps_line + elevated_command build the one PowerShell line every elevated launch uses (the NVIDIA
power cap, the sweep helper, the clock sync, an elevated remote job), -WindowStyle Hidden by construction; unit
tests on the line, the quoting and the Command.
- jobrun.rs: the elevated job path uses it; the relaunch helper's Start-Process carries the reason it has no
-WindowStyle Hidden (igneum-app.exe is a windows-subsystem program).
- tools/ci/windows-spawn-check.mjs (+ ci.yml): fails when a Command::new in app/igneum-app/src is not quieted,
a creation_flags is not CREATE_NO_WINDOW alone, a Start-Process the Rust code writes lacks -WindowStyle Hidden or
-NoNewWindow, or host.cpp spawns without CREATE_NO_WINDOW / SW_HIDE; self-test on known-good and known-bad samples.
- tools/windows/console-watch.ps1, console-watch-bg.ps1, console-watch-elevated.ps1: the watchers (run jobs).
