nexxo	8f2252e81b	Book a downgrade for a date that cannot move, and sell a module once ... Two ways of charging a customer for something they did not get. A downgrade was due when `subscriptions.current_period_end` said so, and Stripe pushes that column forward on every renewal. So a downgrade booked in March was deferred to the end of April by April's renewal, and to the end of May by May's — each time by a whole term, and each time the customer was billed again for the package they had asked to leave. The due date was being re-derived from a moving target on every scheduler tick. It is decided once now, at the moment the customer decides, and stamped onto the contract: `pending_plan` and `pending_effective_at`, the two columns that have been in the schema since the first migration and were written by nothing at all. The shop stamps them, PlanChange reads them instead of the period end when a move is already booked, and clupilot:apply-due-plan-changes finds contracts by the stamped date rather than orders by a date it recomputes. The order stays what it always was — the customer's own record of the request, what the cart shows them and what they remove to change their mind — so it is still consumed with the change, and removing it unbooks the change. What it no longer does is decide when. A second downgrade replaces the first rather than queueing behind it; an upgrade clears one, or it would come due months later and undo the bigger package; a contract cancelled before the date takes the booking with it; and a customer with no contract can no longer place a downgrade at all, which was accepted before and could never be carried out. A booked change is now visible where the contract is read: on the plan card in the portal, because the cart entry disappears when it is paid for and the booking does not, and on the customer row in the console, because that is where an operator answers "what is this customer on". The second defect is the same money in one step: BookAddon guarded duplicates per ORDER — the unique index on (order_id, addon_key) — so two orders for the same module on one contract both went through. A stale tab or a double click bought priority support twice. But storage is deliberately sold in packs, and AddonCatalogue sums the quantities for exactly that reason, so "refuse the second" is only right for some of them. Which is which is declared beside each price in config/provisioning.php (`sold_as`), because it is a commercial decision about each module and not something to infer from a key: storage is a quantity; off-site backups are on or off, support is prioritised or it is not, Collabora Pro is one licence, and a machine answers to one own domain. An undeclared module counts as an entitlement — the cheaper of the two mistakes — and a test refuses to let one ship undeclared. Enforced in the action, where the portal, the console's grant screen and a webhook all pass, with the sentence the customer is shown rather than a developer's. A retried webhook for the SAME order still gets its one booking back; that is one purchase arriving twice, not two purchases. The portal stops offering what would be refused — booked, or already waiting in the cart — and goes on offering the pack. What is missing is on the Stripe side and is not invented here: nothing moves the subscription's item onto the new Price, so the renewal after a plan change still bills the old plan at Stripe. StripeClient only creates and archives catalogue objects, and swapping a price also needs the subscription ITEM id, which nothing stores.

nexxo	34874adec3	Apply a bought plan change instead of only pricing it ... 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.
