# resolve-cmm-bay-config.ps1 - Resolve CMM bay config from cmm-bay-config.csv.
#
# Called by startnet.cmd after the bay picker. Reads the CSV from the PXE
# enrollment share, looks up the selected CMM ID, and writes:
#   W:\Enrollment\cmm\version.txt   (e.g. "2019")
#   W:\Enrollment\cmm\doda.txt      (e.g. "yes" or "no")
#
# 09-Setup-CMM.ps1 reads these at install time to gate which PC-DMIS
# version gets installed and whether DODA is deployed.
