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.

Customers can now see what they have used and what is left, and the service
slows down rather than stopping when the allowance is gone — a slow Nextcloud
gets a top-up, a dead one gets a cancellation.
- instance_traffic keeps one row per instance per month. Proxmox counters are
cumulative since the VM last started, so usage is the difference between two
samples, and a counter that went backwards means a restart, not a refund.
- Outbound is what counts: inbound is free at our providers and egress is what
Hetzner's 20 TB per server applies to.
- CollectInstanceTraffic samples every 15 minutes, warns once per threshold
(80/95 %) rather than on every run, and at 100 % limits the VM's NIC via
Proxmox — released again as soon as the customer tops up or the month rolls
over.
- The dashboard gets a full-width band (it throttles the service, so it is not
a tile among tiles) with the top-up offer right next to the warning.
- Bytes are formatted in SI units now: allowances are computed in SI, so
dividing by 1024 made a 1000 GB plan read as "931 GB".

The console can now create, block and remove VPN accesses, and shows who is
actually connected — traffic counters, source endpoint and last handshake.
Design notes:
- The web container has no wg0, so the page never talks to WireGuard. Live
state is copied in by SyncVpnPeers on the provisioning queue (the only worker
whose container owns the interface); the page polls the database and merely
nudges that job, throttled so many open tabs cannot flood the queue.
- enabled (operator intent) and present (observed on the hub) are stored
separately, so a sync can never quietly undo a block and drift stays visible
as "wird angewendet".
- The sync adopts peers the host pipeline registered, naming them after their
host — otherwise "who is on the VPN" would have blind spots.
- Keypairs are generated in PHP via libsodium rather than shelling out to
wg genkey (no interface in this container, and it keeps generation testable).
The private key is shown once and never stored.
- allocateIp() now also considers vpn_peers, which would otherwise be handed a
tunnel address a host already holds.
- vpn.manage is a new capability held by Owner/Admin only, and it hides the nav
entry too — a VPN access reaches the management network.
Verified end to end against the real hub, not just mocks: created an access in
the browser, connected with the generated config, watched the console flip to
"Verbunden" with real counters, then blocked it and confirmed the peer was
gone from wg0 and the client could no longer handshake.
