Standard-Machine: UDC data backup + restore scripts for PC swap workflow
Backup-UDCData.bat / Backup-UDCData.ps1: tech-runnable, UAC-self-elevating. Run on the OLD PC before retirement; reads bay number from udc_settings.json, copies CurrentData.json + ArchiveData/ to \\tsgwp00525\...\backup\udc\<bay>\, drops backup.manifest.json. Refuses the 9999 placeholder so backups never collide across PCs. Restore-UDCData.ps1: idempotent, designed for the manifest engine. 99% of cycles silent no-op (sub-second, zero side effects); 1% (cycle after a backup lands at this PC's bay) restores files locally, moves consumed backup to <bay>\migrated\<timestamp>\, writes restore.manifest.json, relaunches UDC. Round-trip + no-op fast path verified end-to-end on the win11 analyzer VM. Already wired into the Standard-Machine GE-Enforce manifest at standard-machine\manifest.json on the v2 share. Complementary to the placeholder-to-real branch in Update-MachineNumber.ps1: that branch covers the 9999 -> real flow, this one covers the pre-imaged-then-swapped flow where Update-MachineNumber already ran before any backup existed. Both safely no-op if the other consumed. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

REM Backup-UDCData.bat - Tech-runnable wrapper for Backup-UDCData.ps1.
|

REM
|

REM Self-elevates via UAC so the script can read C:\ProgramData\UDC\* and
|
||||
REM write to the SFLD share with the right cached creds. Forwards any
|
||||
REM extra args verbatim (e.g. -KeepPriorBackup, -MachineNumber 7605).
|

REM
|

REM Usage on the OLD PC, before retirement:
|
||||
REM 1. Double-click Backup-UDCData.bat (or right-click -> Run as admin)
|
||||
REM 2. Approve the UAC prompt
|
||||
REM 3. Watch the elevated PS window for the success summary
|
||||
REM 4. Confirm \\tsgwp00525.wjs.geaerospace.net\shared\dt\shopfloor\backup\udc\<machine>\
|

REM now contains CurrentData.json + ArchiveData\ + backup.manifest.json

# Restore-UDCData.ps1 - Idempotent UDC data restore for the manifest engine.
|

#
|

# Triggered by the GE Shopfloor Enforce scheduled task (runs as SYSTEM, every
|
||||
# user logon + every 5 min). Standard-machine manifest entry uses
|
||||
# DetectionMethod=Always so this fires every cycle; the script self-decides
|

# whether there's actually any work to do.
|

#
|

# CONTRACT:
|
||||
# - 99% of cycles: no backup waiting -> exit 0 in ~1 second, no side effects
|
||||
# - 1 cycle (the one after Backup-UDCData lands a backup for this PC's bay):
|
||||
# stop UDC, copy CurrentData.json + ArchiveData/ to C:\ProgramData\UDC,
|
||||
# move consumed backup to <bay>\migrated\<timestamp>\, write
|
||||
# restore.manifest.json, restart UDC. After this, root is empty so the
|
||||
# check returns "no backup waiting" again on subsequent cycles.
|
||||
#
|
||||
# DESIGNED FOR THE SWAP WORKFLOW:
|
||||
# New PC gets pre-imaged with real machine number + locked down, sits in
|
||||
# storage. Days/weeks later, tech runs Backup-UDCData on old PC -> backup
|
||||
# lands on share. Tech swaps PCs. New PC powers on at the bay -> ShopFloor
|
||||
# autologon -> manifest engine fires this script -> backup detected ->
|
||||
# restored -> UDC opens with prior history intact.
|
||||
#
|
||||
# Replaces the placeholder->real trigger in Update-MachineNumber.ps1 for the
|
||||
# pre-imaged-then-swapped case (where the trigger fired at imaging time, before
|
||||
# the backup existed). Update-MachineNumber.ps1's branch still handles the
