# wait-for-internet.ps1 - Invoked by FlatUnattendW10-shopfloor.xml as Order 4
# during first logon, right before GCCH enrollment. Previously the logic was
# inline in the unattend's CommandLine attribute but the string exceeded
# Microsoft's SynchronousCommand CommandLine length limit and Windows rejected
# the whole answer file with "the answer file is invalid". Moved here to keep
# the unattend CommandLine short.
#
# Behaviour:
#   1. Print a 60-second prompt asking the tech to connect to production
#      network. Gives tower users a window to unplug PXE cable and re-cable
#      to a production port; laptop users are already on WiFi and can
#      press any key to skip.
#   2. Poll TCP 443 to login.microsoftonline.us for up to 10 minutes using
#      Test-NetConnection (NOT Test-Connection / ICMP - Microsoft 365 edges
#      do not reliably respond to ICMP, which previously caused infinite
#      "Waiting for internet connectivity..." loops on towers).
#   3. Always exit 0 so the unattend chain proceeds even if detection times
#      out - enrollment will retry on its own if the network is still broken.
