[Unit]
Description=HAPX-UI auto-update check (every ~15 min, jittered across the fleet)
Documentation=https://gitea.itm-technologies.de/ITMGmbH/HAPX-UI

[Timer]
# First check shortly after boot, then every 15 min. RandomizedDelaySec spreads
# the fleet over a 10-min window so a bad release never hits every box in the
# same second (each box also independently backs up + health-gates + rolls back).
OnBootSec=5min
OnUnitActiveSec=15min
RandomizedDelaySec=10min
# Catch up one missed run after downtime, but don't stampede.
