The ancestor walk only exempted the unsloth.exe shims and stopped at the redirector, so the installer flagged its own launcher and every Windows install failed with "The managed Studio environment is in use by unsloth.exe". Carry one redirector as pending and exempt it only when a shim sits directly above it, so a managed backend that spawns an update still blocks. Also stop gating the protected shim paths on exists(), so a shim renamed out of the way mid-update is still recognised. Drop "Studio" from the two runtime-lock messages so process.rs satisfies the desktop branding contract. * Close the redirector exemption when the updater is the managed image Only a base interpreter runs under a venv redirector. If our own executable is inside the managed root there is no redirector above us, so a managed parent is a real consumer and must keep blocking. Adds the regression to the redirector test. * Key the redirector exemption on sys.executable, not on a shim above it The Tauri updater runs `<venv>\Scripts\python.exe -I -c ... studio update` directly, so its chain is tauri.exe -> redirector -> base Python with no unsloth.exe in it. Requiring a shim above the redirector made every desktop update block on its own launcher. A venv redirector starts base Python as a child and waits, so when we are the base image and sys.executable still names the managed interpreter, our direct parent is that launcher. Exempt exactly that hop; ancestors above it must still be shims, and a managed image at depth two or more keeps blocking. * Stop the x86 guard test racing its own probe The 32-bit leg fired one scan against a probe that lives about five seconds, while a WOW64 shell start plus the Add-Type compile regularly costs more than that, so it read an empty list on a Windows runner. Give the probe a long life and retry like the 64-bit sibling already does. The assertion is unchanged. * Tighten comments in the Studio runtime gate changes --------- Co-authored-by: pre-commit-ci[bot] <66853113+pre-commit-ci[bot]@users.noreply.github.com> Co-authored-by: danielhanchen <michaelhan2050@gmail.com>	2026-08-07 05:24:40 -07:00
