A VPS resized from 1 vCPU/1 GB to 4 vCPU/8 GB with a 60 GB volume attached,
and the panel never mentioned any of it. Not a stale cache: a resize forces a
power-off, so the process and its in-memory spec cache die and the next boot
reads the truth. The gap is that nothing ever persisted the PREVIOUS numbers,
so there was nothing to compare against — and the reboot that causes the
change is what destroys the only copy of the baseline.
Adds host_snapshots: capture specs + per-filesystem inventory at boot, diff
against the last row, and emit host.specs_changed / host.storage_advisory on a
real delta. Advisories fire on state transitions only, so an unfixed fstab
entry does not nag on every restart.
Repairs a divergence this exposed: resource_tier_service measured the first of
/var/lib/serverkit,/var/lib/docker,/ while capacity_service hardcoded /. Both
now use host_inventory_service.data_path(), and local headroom reports which
mountpoint it measured.
Notifications render in the existing bell UI, so no frontend change is needed.
