# SQL templates
#
# All device sections use unified DB column names so the JSON output
# has consistent field names across new_devices, down_devices,
# down_reconnected, and events.
#
# Placeholders:
#   {condition}          — optional WHERE clause appended by condition builder
#   {alert_down_minutes} — runtime value, only used by down_devices
