All shims defaulted to F:\CI\python\venv\Scripts\python.exe when
CI_VENV_PYTHON was not set. On Linux host this caused instant failure.
Now uses $IsWindows (PS 6+ automatic var; absent on PS 5.1 = Windows)
to select /opt/ci/venv/bin/python on Linux. Windows paths unchanged.
Affects: Invoke-CIJob, Get-BuildArtifacts, Cleanup-OrphanedBuildVMs,
New-BuildVM, Remove-BuildVM, Wait-VMReady, Get-CIJobSummary,
Invoke-RemoteBuild, Watch-DiskSpace, Watch-RunnerHealth,
Set-CIGuestCredential, Test-CIGuestWinRM.

The blind -X -> --x shims forwarded PowerShell common parameters
(-ErrorAction, -Verbose, ...) to the Python CLI, e.g.
Measure-CIBenchmark.ps1 -> Remove-BuildVM.ps1 -ErrorAction
SilentlyContinue produced `ci_orchestrator vm remove --error-action`
-> "No such option" -> destroy failed (orphan VM left). Skip
common switches and consume value-taking ones. Applied to all 7
blind-loop shims; param-style shims (New-BuildVM, Invoke-RemoteBuild,
Get-BuildArtifacts) are not affected. PSSA clean.

§4.1 — Structured JSONL log (Invoke-CIJob.ps1)
Each job now emits a parallel invoke-ci.jsonl alongside the transcript.
Write-JobEvent appends one JSON line per phase transition (ts, jobId,
phase, status, data). Events emitted at: job.start, phase1.clone-repo
start/success, phase2-3b.vm-start start/success, phase4.wait-ready
start/success, phase5.build start/success, phase6.artifacts start/success,
job.success/failure (with elapsedSec and error string).
Silent no-op if $jsonLog is null (log dir setup failed). Errors in
Write-JobEvent are swallowed — logging never breaks the build.
Enables post-hoc per-phase duration analysis with jq or ConvertFrom-Json.
§4.3 — Disk space alert (scripts/Watch-DiskSpace.ps1)
Checks drive free space every 15 min (scheduled by Register-CIScheduledTasks).
Below MinFreeGB (default 50 GB): writes Warning to Windows Application Event Log
(source CI-DiskAlert, EventId 1001) and exits 1 so Task Scheduler flags the run.
Optional -WebhookUrl for Discord/Gitea webhook notification.
Register-CIScheduledTasks.ps1 updated with Task 3: CI-DiskSpaceAlert (every 15 min).
§4.4 — Incident runbook (docs/RUNBOOK.md)
Four scenarios with symptom / triage commands / fix / escalation:
1. Runner offline in Gitea UI
2. All builds fail in Phase 2 (clone/start/IP)
3. Builds are slow (per-phase JSONL analysis, disk/CPU/NAT checks)
4. Template VMX corrupt after host crash (lock removal + backup restore)
Quick-reference table at the end.
