# Report-AssetToShopDB.ps1
#
# Reports a PC's identity to ShopDB (Flask) so the computers/machines record
# stays current with whatever the PC actually is right now: hostname, BIOS
# serial, pc-type, logged-in user, DNC machine number (2001, 2002, ... when
# present) and its corp/AESFMA IPv4 address.
#
# TARGET: the ADR-006 collector API.
#     POST <shopdb>/api/collector/computers
# The server is NOT baked in. It comes from HKLM:\SOFTWARE\GE\ShopDB BaseUrl,
# which Install-GEEnforce.ps1 provisions and the enforcement client already
# needs, or from -ApiUrl in the manifest entry's Args. ADR-015: a site name in
# product code is a defect, and this script ships to every site.
# The computers plugin's apply_collector_payload upserts idempotently by
# hostname (create if missing, patch-style update if present - only the fields
# posted here change, so it never clobbers model/VNC/WinRM). Machine number maps
# to Asset.assetnumber; the placeholder 9999 is skipped server-side.
#
# AUTH: the collector API does NOT honor the GE-Enforce IP allowlist (that only
# covers the geenforce fetch/report endpoints). It needs a collector.ingest key,
# sent as the X-API-Key header. The key is read from HKLM:\SOFTWARE\GE\ShopDB
# CollectorKey (same secret store the GE-Enforce client uses; provisioned at
# imaging), or overridden via the manifest entry's Args -ApiKey. Never bake the
# key into the manifest JSON on the share.
#
# Deployed in common\ (runs on EVERY shopfloor pc-type). Non-DNC bays report
# identity with no machineNo, so no PC-to-machine link is built - by design.
# Runs every GE-Enforce cycle as a Type=PS1 / DetectionMethod=Always entry under
# the SYSTEM task. Always exits 0 so "last run result" stays clean; failures are
# logged, never thrown.
#
# WHY ONE NIC ONLY:
#   Some bays carry two NICs - a private controller NIC and the routable
#   corporate NIC. Only the routable one belongs in ShopDB. A site may name its
#   corporate ranges (-AllowedRanges, or the CollectorRanges registry value); with
#   none configured the NIC carrying the DEFAULT ROUTE is used, which expresses
#   the same intent without knowing any site's addressing.
