HA: add binary_sensor.vault1_cifs_mounted (grep /proc/mounts every 5 min),
rest_command.vault1_push_heartbeat, and two automations — heartbeat push to
Uptime Kuma push monitor (id=45, 10-min timeout) and direct ntfy alert if
CIFS drops for >3 min. Catches the sda8-fallthrough scenario in <8 min.
Runbooks: root cause of credential file loss is NOT unclean shutdown but
the HAOS 17.3 supervisor (2026.05.x) deleting the cred file during mount
reload cycles. Exact moment: 2026-05-22 00:53:31 UTC, 13 min after the
HAOS 17.3 first-boot successful mount. NUT gap documented (HAOS not a NUT
slave); recommended to add Community NUT addon targeting cyberpower1@.200.
