PlanChange could say what a move would cost and whether it was allowed, and
that was all it could do. Billing::purchase() wrote an upgrade order and
nothing ever consumed it: same snapshot, same machine, same quota. A customer
could pay for a bigger package and receive nothing.
ApplyPlanChange is now the single place a change lands — it moves the contract
onto the target's current version, writes one register row, settles the custom
domain, and starts a run that resizes the machine. Applying the same order
twice is a no-op, enforced by a unique event key rather than by a check two
callers could both pass.
Two things a plan change must not do, and now does not. A disk is never shrunk
— Proxmox cannot, so the QUOTA shrinks instead, which is what was sold anyway.
And a live machine is never rebooted as a side effect: cores and RAM are
written, and where they need a restart the instance says so where an operator
and the customer can both see it.
The storage allowance also joins the build pipeline. ApplyStorageQuota was
written for plan changes and ran only there, so a brand-new customer still got
no quota at all — quota_gb reached the instance row and stopped, and every
package delivered the whole disk. The test guarding that pipeline only counted
its steps, which is how a list missing the one step that makes a package's
storage real stayed green for its whole life. It now names the step.

A verified custom domain was reported as the customer's address by
Instance::address(), by the portal and by the credentials mail while
nothing on the platform routed it: the Traefik router's rule was
hard-coded to {subdomain}.{zone}. The address a customer was handed
answered nothing, and a withdrawn domain stayed in Nextcloud's
trusted_domains forever, because the only thing that ever wrote either
was the initial provisioning run.
- TraefikWriter::write() takes a LIST of hostnames under one stable
router name — the platform address always, the verified domain as
well when there is one. One file per instance, so a withdrawal is a
rewrite rather than a second thing somebody has to remember.
- ConfigureDnsAndTls records the custom domain's certificate instead of
waiting on it: it depends on an A record in the customer's own zone,
which may never appear, and must never fail a run. The platform
address keeps its 840s deadline. instances.domain_cert_ok tells
"proven" apart from "answering", and the portal now says which.
- ConfigureNextcloud deletes trusted_domains 2 when there is no verified
domain, so a withdrawn one stops being trusted.
- New `address` pipeline (those two steps) plus ReapplyInstanceAddress,
which starts one against the order and refuses to start a second while
any run is in flight. The route is rewritten when the hostname list
differs from what the router carries — not on route_written, which
would short-circuit exactly the case a re-apply exists for.
- Triggered where the address changes: verification flipping either way
in clupilot:verify-domains, the customer's own domain page, and
CustomDomainAccess::deactivate() on a package downgrade.
- A maintenance run no longer condemns its subject: an address run that
failed used to mark the order failed and release the live instance
with it.
