The tile shows Home Assistant's own used figure beside the total, so it matches Home Assistant's storage page. An OS update doesn't reboot the machine: Supervisor writes the image, reports the new version and raises a repair asking for a reboot. The confirmation, schedule warning, MCP docs and plugin docs now say so. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

"""Installing what's waiting at a weekly slot: one at a time through the same path

the OS last, as it waits on a reboot. The first failure ends the slot, leaving the

rest for someone to look at. Everything is on the rows, so a restart of Steward or
