Verification tooling for the Windows freeze assessment (T-424). provision-vm.sh stands up a Windows KVM guest (dry-run unless --go); bootstrap-windows.ps1 installs Flutter + VS C++ Build Tools and checks out the branch; soak-conpty.ps1 runs the pty suite in a fresh dart.exe per iteration and measures the orphaned conhost/cmd count that survives each exit (the leak signature), with a per-iteration timeout so a wedged test can't stall the run. Verifies the ConPTY leak (#1-#4); the GPU/TDR hypothesis (#5) needs passthrough/bare metal (README appendix). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

# Provision a Windows VM on a Fedora/KVM host (this is "danoontje") for the
|
|
# ConPTY soak verification. REVIEW BEFORE RUNNING — by default this is a
|
|
# DRY RUN that only prints what it would do. Pass --go to actually execute.
|
|
#
|
|
# Scope: this VM verifies the ConPTY *resource leak* (culprits #1-#4). It does
|
|
# NOT verify the GPU/TDR hypothesis (#5): a stock VM renders through a software
|
|
# (WARP) adapter, so `make run` cannot exhibit a real display-driver TDR here.
|
|
# Chasing #5 needs GPU passthrough (vfio) or bare metal — see README appendix.

# Prereqs you must supply:

# WIN_ISO path to a Windows 10/11 or Server 2022 install ISO

# VIRTIO_ISO path to the virtio-win ISO (storage/net drivers)
