# resolve-bay-config.ps1 - WinPE-runnable bay-config resolver.
#
# Reads bay-config.csv (per-asset ftpak_version + model + user_id) and
# writes the matched row into per-field text files under $OutDir, so the
# rest of startnet.cmd + the post-imaging 09-Setup-WaxAndTrace.ps1 can
# read them as single-line files (cheaper than re-parsing CSV in batch).
#
# Outputs (under $OutDir, default W:\Enrollment\waxtrace\):
#   version.txt   - exact FormTracePak version (matches an installer ISO label)
#   model.txt     - sub-version (AVANT / CV-4500 / CV-3200)
#   userid.txt    - per-bay license USER ID
#   bay-info.txt  - human-readable audit dump (timestamped)
#
# Exit codes:
#   0 - row found + files written
#   1 - asset_tag not in bay-config.csv (Wax/Trace install will abort cleanly)
#   2 - bay-config.csv missing or unparseable
