# gps-rmm-progress-check.sh — daily GPS->GuruRMM enrollment progress check.
#
# Reads projects/gps-rmm-audit/targets.json (GPS device target per client),
# pulls live GuruRMM /api/agents, computes per-client enrollment gaps, and DMs
# Howard a one-message summary. When every tracked client has met its target it
# reports "COMPLETE" so the scheduled task can be retired.
#
# Usage:
#   bash gps-rmm-progress-check.sh            # check + DM Howard
#   bash gps-rmm-progress-check.sh --dry-run  # check + print, no Discord
#
# Registered as a daily Windows scheduled task. Read-only against RMM.
