Root cause found via decompiling UDC_Setup.exe: it never writes
udc_settings.json from CLI args. Instead it pulls
Settings_Backups\udc_settings_<num>.json from \\tsgwp00525\shared\SPC\UDC
-- which is unreachable at imaging time (no SFLD creds yet). Silent
File.Exists() false, settings never copy, UDC lands on Evendale defaults.
Fix: stage 80 udc_settings_*.json backups under
shopfloor-setup/Standard/udc-backups/ (same tree as ntlars-backups,
xcopy'd to C:\Enrollment\ by existing startnet.cmd). 00-PreInstall
pre-creates C:\ProgramData\UDC\udc_settings.json from the matching
backup BEFORE UDC_Setup.exe runs. Installer's server-side copy silently
fails (unreachable), our pre-staged file survives.
Also:
- preinstall.json UDC InstallArgs corrected: "West Jefferson" -9999
(quoted spaced site + dash-prefixed number, confirmed via decompile)
- Update-MachineNumber.ps1 UDC.exe relaunch: quoted site + dash number
- Monitor-IntuneProgress: action prompts (Select Device Category after
Phase 1; Initiate ARTS Lockdown after Phase 5/creds), Display flow
(3-phase: Registration -> Config -> Lockdown), Phase 6 IME-based
lockdown detection
