Faster lab runs

Replaying the runs of 16 and 19 October through the old and the new scheduler (offline, from their console.log) shows the Server VMs bound a full run: their own files plus the time Console files hold them. Reordering alone gains nothing; a third lane and the quick build check do:

Run	2 lanes	3 lanes
Full (16 Oct / 19 Oct)	8.3 h / 6.1 h	5.6 h / 4.0 h
-Quick	5.4 h / 3.4 h	3.7 h / 2.3 h

• Scheduler (Invoke-LabTests.ps1, Select-LabNextRun): the longest files start first; a file that uses another VM (Get-LabDevice) takes a free one of any lane (RHLAB_DEVICES); a file's time limit is twice the longest it took before (at least 20 min, never above its own).
• Start-LabRun.ps1 -Quick: device files on the W11 VMs only; files with Server-only parts say # LabQuick: every kind (S-SHARE, S-SHARE2, J-JUMP, W-SETUP2).
• -FailFast: Pester SkipRemainingOnFailure = Block; no more files start once 4 in a row passed nothing.
• Options reach the run through results\<run>\options.json (the queue passes only -Vm / -Tag, so the watcher needs no restart); it also records the commit, repeated in run.json.
• Timing: each file run writes pester-<file>.xml.timing.json (minutes in the module's slow helpers, outermost call only, and the file's own time); Get-LabTimings.ps1 sums a run up – where to start making tests faster.

RemoteHub Lab app

lab\LabConsole (WPF-UI, links RemoteHub's AppChrome / AppIcon), built into one file lab\RemoteHubLab.exe (git-ignored) by build\build-lab-tool.ps1.

• Tests as group › file › case with status pills (passed, failed, skipped, not run, pending, running), progress bar and time left, file runs, failures, output.
• Quick build check, Fail fast, Run again when it ends, until stopped (new cases picked up when everything is selected), Changed since full run (git's changes since the last full run's commit, mapped to test files by area).
• Always on main: it keeps its own detached worktree of origin/main (C:\rh-lab-main) and brings it up to date when it opens and before every run; it copies the newest agent build of any worktree (and the one before it) into that checkout's artifacts\, plus the git-ignored lab.local.json / lab-signing.cer from the checkout it was started from.
• Unit tests in lab\LabConsole.Tests (catalog, change detection, run log, estimate, quick-run plan, changed areas).

Cases

• C-NOTE-01..12 (C-NOTES.Tests.ps1) in section 10.8 next to UI-NOTE; POL-14 / POL-15 automated in POL-CLIENT; D-BAN-11 in D-MORE; case tags on D-SHELL and D-CADHIDE. New module helpers Invoke-LabInSessionJson, Invoke-LabClientSql.
• Notes fix (separate commit): a page deleted before its section (or a section before its notebook) dropped out of Recently deleted and was purged with the parent – Deleted() / PurgeDeleted() now LEFT JOIN the parent. Found by C-NOTE-09; unit test added.

Tested

• dotnet build RemoteHub.sln: 0 warnings; Notes unit tests 25/25; lab\LabConsole.Tests 6/6.
• Lab scripts parse, ASCII-only, Windows PowerShell 5.1; scheduler checked against sample lab states, timing wrappers checked without a VM.
• Not yet run in the lab: the new scheduler, -Quick / -FailFast and the C-NOTE / POL-14 / POL-15 cases after their fixes (D-BAN-11 passed in run 20261019-190129).
