nexxo 8440266ed3 Stop charging for a service that has ended
Nothing in this application could cancel a Stripe subscription — there was
no such method on the client at all. So a customer who cancelled and a
consumer who withdrew both stayed subscribed, the card went on being
charged every month, and every one of those payments arrived as
invoice.paid, drew a real number out of the gapless Austrian series and
mailed the PDF, for a machine that had been switched off. Indefinitely.

StripeClient::cancelSubscription() closes the first half, with the timing
passed explicitly at the call site — CANCEL_AT_PERIOD_END for a
cancellation, because the customer keeps the term they paid for, and
CANCEL_IMMEDIATELY for a withdrawal, because that unwinds the contract and
the whole amount has just gone back. The immediate form states prorate and
invoice_now as false rather than inheriting them: a credit note of Stripe's
beside our own Storno would be the same money twice.

The second half is ApplyStripeBillingEvent::owesADocument(). Refusing every
invoice on a cancelled contract would lose the legitimate final one — the
cycle for a term the customer really did use, unpaid, dunned for three
weeks and settled after the contract ended. So the question is not when the
payment landed but what it is for: an invoice whose billed period STARTED
before the contract ended is documented, one whose period begins at or
after that moment is not. Neither is a contract marked cancelled with no
date, nor an invoice with no period, because a number handed out in error
can never be withdrawn while a missing document can still be issued. The
register entry is written either way — the money moved, and that is where an
operator finds what has to go back.

A cancellation also took its date from the order date plus MONTHS, whatever
the term said, so a yearly customer who cancelled in March lost the nine
months they had already paid for. It reads current_period_end now, which
Stripe keeps current for both terms; the month-walk survives only for a
machine with no contract behind it, where nothing records a term at all.
Stripe is asked first and our rows are written only if it agreed: a
cancellation we could not make effective is the defect above wearing a
"gekündigt" label on the settings page, and a cancellation has no deadline,
so being asked to try again costs nobody anything.

A withdrawal cancelled the OPENING invoice only, found by invoices.order_id
— which a renewal and a module document leave null on purpose. A storage
pack booked on day three and withdrawn from on day ten was therefore
neither cancelled nor refunded. Every charge inside the window is covered
now, one Storno per document and one refund per payment, each against the
payment that actually took it: a single refund of the total against the
opening PaymentIntent is what Stripe would have refused for exceeding it,
and one idempotency key for the whole withdrawal would have had Stripe
replay the first refund's answer for the second.

StartCustomerProvisioning::resume() opened a missing contract and returned,
and the only production call to IssueInvoice::forOrders() is after the order
commits — so a worker killed in between cost that customer their invoice for
good, silently, with nothing anywhere sweeping for it. resume() finishes that
work too, guarded by the invoice already filed against the order and by
invoices.sent_at, so however often Stripe redelivers it comes out as one
invoice, one number, one mail. The order confirmation stays on the first
pass alone: it has nothing to stamp.

subscriptions.cancel_requested_at is new because the billing half of the
application had no way to tell a cancelled contract from an untouched one.
Deliberately not a status: until the term runs out this is a paying
customer, which is the distinction EndInstanceService is built around, and
`cancelled_at` beside it still means the day it genuinely ended.

clupilot:verify-vat-ids is scheduled monthly on the first, and its docblock
no longer points at a note in routes/console.php that never existed. Reverse
charge rested on a one-off VIES answer, a withdrawn registration keeps
earning rate 0 for ever, and the unpaid VAT on those invoices is the
seller's — so the cadence is the width of that window, and the first of the
month is the rhythm the return is filed on.

Two tests that proved nothing are now about behaviour. SettingsTest asserted
service_ends_at was not null, a column the code had just written and which
the broken monthly arithmetic satisfied exactly as well as the right answer;
it states the yearly date, the contract's own record and the order to Stripe.
EndInstanceServiceTest travelled to whatever value the implementation had
computed, so it recomputed the code instead of checking it, and never looked
at billing at all; the boundary is a literal date now and the money stopping
is asserted beside the address coming down.

nexxo 20329b176b Refuse a portal login for an address that already belongs to an operator
Customer::ensureUser() enforced uniqueness only within users, so a
customer provisioned (or registering publicly) with an operator's email
got a second, colliding identity for the same address — the exact thing
R21 exists to prevent. Checks Operator by address now, not by session
(the deleted assertNotAdmin() checked who was signed in, which could
never be the right question).

Public registration gets the same guard via a plain unique() validation
rule, reusing Laravel's stock "already taken" message rather than a
dedicated one — naming the collision specifically would tell a public
visitor an address belongs to staff, a worse leak than the generic
refusal every other collision here already gives them.

Impersonation answers 409 instead of crashing into it. The Stripe
webhook keeps recording the paid order (same principle as
openContract()'s own comment: the order is proof money changed hands)
and withholds only the colliding login, logged for an operator to
resolve by hand.

Verified the reverse direction Codex flagged as already covered: two
Admin\Settings actions and the clupilot:create-operator command all
already refuse an operator email that collides with a customer's, and
that check is sound today because every users row is created in
lockstep with a customers row of the same email (CreateNewUser and
ensureUser are the only two creation sites, both confirmed by grep) and
nothing in this app can change a user's email afterwards (Fortify's
updateProfileInformation feature is disabled, and no other code calls
that action).

nexxo 0560ae743d feat(billing): Stripe owns the billing cycle, we own capability
A Product per plan family and a Price per priced row of a published version,
plus the four subscribed webhook events that were arriving and being ignored.

`stripe:sync-catalogue` mirrors the catalogue. Idempotent twice over: a stored
id is skipped, and each call carries an idempotency key derived from our own
row, so a crash between Stripe creating a Price and us recording its id gives
back the same object rather than a second one. That matters more here than
usual — a Stripe Price cannot be edited or deleted, so a duplicate is
permanent. Drafts are not synced at all: a version that has promised nothing
has no business in a price list. --dry-run shows what would be created.

The webhook now handles invoice.paid, invoice.payment_failed,
customer.subscription.updated and customer.subscription.deleted. It never
re-derives an amount: the invoice is the authority for what was charged, and
recomputing it from our catalogue would produce a second, disagreeing answer.
A failed payment is recorded and nothing else — Stripe runs the dunning
schedule, and cutting a customer off on the first failure would punish an
expired card as though it were a refusal to pay.

Only a cycle renewal moves the term on. Stripe also sends paid invoices for
prorations and manual charges, and the checkout's own invoice — which is
already in the register as the purchase, and would otherwise double every
customer's first payment.

Stripe does not guarantee delivery order, which is the source of most of the
care here:
- state changes are judged and written in one transaction with the row held,
  so two deliveries cannot both pass a check made on a stale copy;
- an older event never overwrites a newer one, with a rank breaking ties
  between events sharing a second — their timestamps have one-second
  resolution, and a failed attempt and its successful retry routinely do;
- a term is never shortened, and an ended contract is never revived;
- an event for a contract that does not exist yet is HELD and replayed the
  moment it appears, rather than acknowledged and forgotten. A cancellation
  dropped that way would leave us serving someone who had already left. Held
  rows that never match are pruned after a week.

Register entries are keyed by what they are about — the invoice, the attempt,
the subscription — with a unique index doing the work, because a check two
concurrent deliveries can both pass is not idempotency.

PlanChange is now documented as the preview shown before someone confirms, not
the invoice: Stripe's proration accounts for tax, existing credit and the exact
second the change lands, and ours cannot.

Not run against the live account — `stripe:sync-catalogue` creates objects that
cannot be deleted, so that is the owner's call. The dry run lists 12.

457 tests green. Codex review clean after seven rounds.

nexxo 64e3ca421d fix(engine-b): async stripe payments, capacity honesty, durable credential mail
- Accept checkout.session.async_payment_succeeded (async methods) and dedupe on
  the checkout session id, not the event id.
- committedGb still counts a failed instance while its VM exists (has vmid);
  releases quota only when no VM was created — no overcommit vs no leak.
- CloudReady is queued (durable). Credential delivery is documented at-least-once
  (a rare duplicate welcome email beats a lost credential; exactly-once = v1.1 outbox).

nexxo fffcecb152 fix(engine-b): address Codex round 3 (webhook email/replay/rotation, db secret)
- Require a real customer email (no unknown@ fallback merging customers).
- Stripe signature: enforce 5-min replay tolerance + accept any rotating v1.
- DeployApplicationStack no longer persists the DB password in the run context.

nexxo 42fa92cf20 fix(engine-b): address Codex (paid-only stripe, guest routing, absolute disk)
- Stripe: only checkout.session.completed with payment_status=paid (dedupes the
  paired payment_intent event and blocks unpaid async sessions).
- Capture the guest IP (ConfigureNetwork) and point Traefik at the VM, not the
  Proxmox host, so ACME/HTTP-01 can reach Nextcloud.
- Resize the disk to an absolute target (not '+…') so a retry can't double it.
(Codex #4 timeout was a false positive — started_at resets per step.)

nexxo 65ba3d6588 feat(engine-b): Stripe webhook -> idempotent customer provisioning intake
Signed webhook (HMAC verify when secret set), CSRF-exempt route. Paid checkout
creates customer+order+run (stripe_event_id unique => duplicate webhooks start
one run) and dispatches. 5 tests.
