powershell.exe does not exist on Linux — child process launch failed
instantly (ExitCode null, Elapsed 00:00). Now selects powershell.exe
on Windows and pwsh on Linux via $IsWindows automatic variable.

PROBLEM: Invoke-RemoteBuild.ps1 was creating a placeholder artifact when the build
produced no dist/ directory. In production this hides build defects (build exits 0
but produces nothing = silent failure treated as success).
SOLUTION: Add explicit -SkipArtifact switch to the call chain:
Invoke-RemoteBuild.ps1:
- Add -SkipArtifact switch. When set: skips packaging entirely (no zip created).
- When absent (production default): missing GuestArtifactSource is a hard error
with a clear message pointing to -SkipArtifact as the opt-in for no-output builds.
Invoke-CIJob.ps1:
- Add -SkipArtifact switch. Passes it to Invoke-RemoteBuild.ps1.
- Phase 6 (Get-BuildArtifacts) is entirely skipped when set; logs 'skipped' event.
Test-CapacityBurnIn.ps1:
- Add -SkipArtifact switch. Adds '-SkipArtifact' flag to each child job argList.
Start-BurnInTest.ps1:
- Always passes -SkipArtifact by default (burn-in uses delay commands, no output).
- Add -NoSkipArtifact override switch for runs that do produce real artifacts.
- Remove -NoSkipArtifact escape from wrapper: default burn-in never needs artifacts.
scripts/Test-CapacityBurnIn.ps1 (new): N-way parallel burn-in harness using Start-Job
to launch N concurrent Invoke-CIJob.ps1 child processes for R rounds. After each round
asserts: all VMs destroyed, all jobs got distinct IPs, vm-start.lock gone, ip-leases
empty, wall time recorded. Params: -RepoUrl (mandatory), -IPList = @() (optional,
auto-detects via VMware Tools when empty), -GiteaCredentialTarget = 'GiteaPAT',
-Parallelism = 4, -Rounds = 3, -RoundTimeoutMinutes = 60, plus all Invoke-CIJob params.
scripts/Start-BurnInTest.ps1 (new): lab wrapper with all default params hardcoded
(template F:\CI\Templates\WinBuild2025, credentials BuildVMGuest/GiteaPAT, etc.)
for daily use. Exposes -Rounds, -Parallelism, -BuildCommand, -RoundTimeoutMinutes.
