The panel could not show the storage ring or the transfer trend because nothing
measured them. instance_traffic keeps one row per billing period — right for an
allowance, useless as a series — and storage consumption was never sampled at
all, so the card could only ever state what was sold rather than what is used.
instance_metrics holds one row per instance per day, written by the traffic
collector on the visit it already makes. A second scheduler entry against the
same Proxmox API would have doubled the load and the failure modes for no gain.
Disk usage comes from `df` inside the guest rather than from Proxmox's own disk
figure, which reports the allocated image: that would show every customer a full
500 GB from their first day.
The rule the whole thing is built on: a reading that could not be taken is not a
reading of zero. The disk columns are nullable and left untouched when the guest
agent does not answer, so yesterday's figure stands instead of the ring dropping
to empty — which would tell a customer their data had vanished. Missing days
stay missing in the series rather than being filled with zeroes, which would
draw an outage that never happened. Both are covered by tests.

The dashboard was built to my own idea of the layout rather than to the
template that was signed off: a coloured pill where the template has a stamped
mono line, bare figures where it has a label with a chevron, a unit on its own
line instead of beside the number, and no ring at all. There is no point
agreeing a design and then building something adjacent to it. The metric card
is now a component that draws the template's form, and the pages use it.
Two more places were still showing data that does not exist:
- Support listed three tickets to every customer, complete with reference
numbers and dates. There is no ticket model; it was fixture text. A request
list also belongs in the console, where an operator can see who filed what.
Removed until there is something real behind it.
- The datacentre name reached the customer through the cloud tab's copy as
well. Customer surfaces name the jurisdiction; the building is operator
information.
And the actions column rendered an empty cell for the owner, who can be neither
re-invited nor revoked. An empty cell reads as a missing feature; it now says
so with a dash and a title.
