A booked storage pack was a row in `subscription_addons` and nothing else:
priced, frozen, charged every month, and delivered nowhere. Nextcloud's
quota came from `instances.quota_gb`, which is the package alone; the disk
was sized for the package alone; and on the one occasion a disk did grow —
a plan upgrade — the guest never saw it, because nothing stretched the
partition or the filesystem over the new space.
One authority for the allowance. StorageAllowance adds the package and the
booked packs, and everything that needs the figure asks it: the quota step,
the downgrade check, the portal, the console, the repair command. It is
DERIVED rather than stored — a column would have to be rewritten by booking,
cancelling, granting, a grant expiring and a plan change, and the day one of
those paths forgot it would be silently wrong in whichever direction costs
somebody money. `quota_applied_gb` keeps its own meaning: what the guest was
last actually told, which is how a machine with the allowance enforced is
told from one where the figure has only ever been a row in our database.
Buying it delivers it. BookAddon asks ApplyStorageAllowance for a run on
booking AND on cancellation; the new `storage` pipeline grows the virtual
disk to the allowance plus the package's own overhead (read off the package
— 20/40/50/100 GB on the four catalogue packages — never a ratio invented
here), then GrowGuestFilesystem makes the guest see it, then the quota is
applied. No cold boot is involved: the data disk is scsi0 and Proxmox's
resize on a running guest is a qemu block_resize, so the capacity reaches
the guest while it runs. The new step rescans, growparts and grows the
filesystem with the tool its type actually needs — ext2/3/4, xfs, btrfs —
and fails loudly on one it does not know rather than handing it to resize2fs
and hoping. Idempotent end to end: NOCHANGE from growpart is not a failure,
and every tool here exits 0 when there is nothing left to grow.
The same step now runs in the plan-change pipeline, where an upgrade used to
stop one step short of the customer.
A downgrade blocked by data gets a way out. The block stays — it is correct
— but the check now measures against the target package PLUS the packs the
customer already owns, and reports the numbers behind the refusal: what is
stored, what would be allowed, how much has to go, and how many packs would
cover it instead. The portal offers both routes: book exactly those packs
(confirmed in a modal, R23), or delete data and have the fill level measured
on demand rather than waiting for the nightly sampler. That reading is taken
by DiskUsageProbe, which CollectInstanceTraffic now uses too, so there is one
notion of "how full is it" and not two.
A plan change keeps booked packs. They were paid for separately and have
nothing to do with which package the customer is on; the new package's disk
and quota are sized with them included.

Three places where the product said one thing and did another.
**Nothing could restart a virtual machine.** ProxmoxClient had startVm and no
way to stop anything, so `restart_required_since` — set by every plan change
that grows a running guest — could only ever be cleared by a resize step that
happened to find the machine stopped, which nothing in the product could
arrange. A paid upgrade's cores and RAM could stay unreached for the life of the
contract, and the cloud page's "Neu starten" was a toast.
There is now a `restart` pipeline: shutdown, start, wait for the agent, confirm.
A shutdown and a start rather than a reboot, because only a cold boot makes qemu
read the VM definition again — a reset would take the machine round and bring it
back exactly as small as it was. The shutdown is a REQUEST, bounded at ten
minutes, and there is no escalation: ProxmoxClient deliberately does not expose
Proxmox's forceStop, because the guest is a Nextcloud and cutting power to a
database mid-write to apply a CPU change trades an inconvenience for a restore
from backup. A guest that ignores ACPI for ten minutes fails the run instead, and
a person decides what happens to it.
`restart_required_since` is cleared by the last step, from what the RUNNING guest
reports (`cpus`/`maxmem`) — not by the button, and not by the run merely
finishing. A machine that comes back smaller than it was sold fails the run.
Started by App\Actions\RestartInstance, which re-checks authorisation itself
rather than trusting a hidden button: an operator holding the new
`instances.restart` may restart anything, a portal user their own machine and
nothing else. Refused while another run is in flight against the same order.
Confirmed in a modal on both sides (R23), addressed by uuid (R11).
**Existing instances had no storage quota.** ApplyStorageQuota reaches new and
changed machines; everything built before it kept the whole disk whatever it had
paid for, and nothing recorded which was which. `instances.quota_applied_gb` is
now what the guest was actually told, written by the step only after the occ call
succeeds — so "sold" and "enforced" are separate facts and can be compared.
`clupilot:apply-quotas` sweeps the estate: one `quota` run per instance through
the same step the pipelines use, skipping what it should and saying why, a no-op
once an allowance is enforced, and inert under --dry-run. Deliberately NOT
scheduled — a nightly sweep would quietly cover for the pipeline step the day it
stopped working, which is how the original hole survived this long.
**A Traefik router was never torn down.** TraefikWriter::remove() had no caller
anywhere. What was missing was the moment: ConfirmCancelPackage wrote a date into
`service_ends_at` and nothing ever went back to it, so every route this platform
ever wrote was written for good — pointing at a guest address the host is free to
reassign. `clupilot:end-due-services` (hourly) keeps that appointment through
App\Actions\EndInstanceService. "Ended" means cancellation_scheduled AND
`service_ends_at` passed, never the day a cancellation is scheduled: that
customer has paid to the end of the term and is working in it. The DNS record
goes with the route — it is in our zone, pointing at a host that serves other
people, which is the shape of every subdomain takeover there has ever been. The
customer's own domain is in their zone and is not ours to touch; the virtual
machine is left alone, because the cancellation flow promises a data export first
and destroying disks is not this change's decision.
