nexxo	865fd16f58	Put the price recognition back, all 3526 lines of it ... 2321854 removed it. That commit's own work — discarding an unconfirmed registration and sweeping abandoned ones — is untouched and correct; what went with it was every file of the Stripe price adoption merged an hour earlier: AdoptStripePrice, IdempotencyKey, the unique-index migration, both test files, the spec, the plan, and the edits in six more. Nothing was lost. The commits stayed in history and the files stayed on disk, untracked, which is what a staged deletion from a stale tree leaves behind. Restored from 4eb90c8, the reviewed head, by explicit path — the fourteen paths 2321854 damaged and not one more, so the ten files that commit legitimately added or changed keep exactly what it gave them. This is the failure the repo's own rule exists to prevent: stage by path, never `git add -A`, because a second session's index does not know what a first one merged.

nexxo	2321854967	Discard an unconfirmed registration, and sweep the abandoned ones ... "Abmelden und neu registrieren" was advice that could not work. Signing out frees nothing: the address is still held by the unique index, so registering again with the address somebody meant fails — and every abandoned attempt stayed in `users` for ever. Reported exactly that way, and it was right. The button discards the account instead. Only an UNCONFIRMED one, and only one with nothing behind it: the webhook creates a customer's login from a paid checkout, so a user can sit on this page unconfirmed while already having a contract, and deleting that is data loss dressed up as a convenience. It refuses and says where to go. A confirmed account is closed, not discarded — that is ConfirmCloseAccount, with an invoice history behind it. R23: confirmed in a modal. The modal mutates nothing; it dispatches the event the page listens for, so the checks stay in the one place they already are rather than being duplicated where they could drift. And nothing has to be discarded by hand. clupilot:prune-unverified removes registrations nobody confirmed after five days — long enough for somebody who signed up on a Friday and found the mail in a spam folder on Monday, short enough that a typo does not hold the correct address for a month. It skips a confirmed account whatever its age, and any account with a customer record behind it, matched on user_id AND on the address, because either link means somebody is a customer. Every removal is logged with the address: a line that disappears is what somebody asks about later, and a count answers nothing. The deadline is said on the page as well as in the mail. Somebody who never received the mail is looking at the page, and the deadline is the reason they do not have to do anything about an attempt they abandon.

nexxo	3cf16ecd63	Name every property that decides what a price charges ... The money gate compared amount, currency and interval and left the rest to a filter that excluded two fields. A recurring, licensed, monthly price with transform_quantity divide_by 10, at our exact figure, on our product, carrying our addon key passed all five conditions. Modules bill BY quantity — a pack is one item at quantity n — so a customer holding three would have been charged one. A tiered price was excluded only by accident: Stripe reports unit_amount null for it and we read that as 0, which fails the amount match unless the caller's own figure is 0, and PlanPrices::ensure() has no zero guard. activePricesFor() now also skips a non-empty transform_quantity and any billing_scheme other than per_unit. Absent keys stay Stripe's defaults, which is the direction that matters: read the other way round the filter would refuse every legitimate price and turn recognition into a permanent no-op. The contract docblock names the four properties instead of claiming to cover all of them, and says the list is not everything Stripe can put on a price — only what is known to change what one charges. And a comment that says a gap is covered is worse than the gap. The sync said a crash between Stripe creating a product and us storing its id gives back the same product next run: true for twenty-four hours, false afterwards, and the exact claim this branch was written to refute. There is no recognition step for products at all, so an interrupted run leaves an orphan and the next run past the expiry mints a second one — worse than a duplicate price, because activePricesFor() then looks at the wrong product and recognition goes blind for the whole family. Written down as a known gap at both createProduct call sites, with the trade this branch chose: folding name and metadata into the key means a renamed family now mints a second product where it used to answer 400, and a blockade reaches a paying customer while a duplicate product does not. The sweep no longer reports "created" for what it adopted — the count is taken before ensure() runs, and telling those two apart is the whole point. The test named after 2026-07-29 could not reproduce it: the fake's key ledger was empty, so createPrice() could not have thrown and the test could not tell "adoption prevented the 400" from "no 400 was possible". Seeded now with the key today's call sends and a fingerprint over the metadata the pre-9da1358 call sent. Remove the adopt() call from AddonPrices::ensure() and the test dies with Stripe's own sentence instead of an assertion. Also: the plan document still instructed migrate:fresh --env=testing. There is no .env.testing here, so it targets the live development database; struck through with the reason, not deleted, and a Korrekturen section records the five defects the plan's own reviews found in it. Four comments corrected — "below" that meant above, a counter claimed unable to tie that ties with a planted price, the unique index's second meaning for remember()'s catch, and that MariaDB DDL is not transactional so the dedupe commits before the index.

nexxo	9da1358802	Stop charging VAT to the customers who owe us none ... A verified EU business outside Austria gets reverse charge — rate 0, no VAT line, the note on the invoice — and was still charged 214,80 € for a 179,00 € package, because one Stripe Price carried the domestic gross for everybody. There is no VAT line on their document to reclaim, so it was a flat 20 % surcharge on exactly the customers who read their invoices, and the document then stated the whole 214,80 € as net at 0 %, so they self-accounted their own VAT on a base a fifth too large. A Stripe Price can ask who is buying after all: there are two per sellable thing now, the domestic gross and the bare net, both live on one Product, and the checkout picks by TaxTreatment. The rule is Austria B2B 20 %, other EU B2B without VAT — a domestic business still pays the gross, reclaims it as input tax, and the price on the website is still the price charged for them. - stripe:sync-catalogue mints and archives both halves of every pair, per plan and per module; `reverse_charge` on stripe_plan_prices/stripe_addon_prices says which is which, and joining it on subscriptions.stripe_price_id says which one a running contract is billed on. A rate change moves the gross Price and leaves the net one alone, because the net owes nothing to the rate. - A status that changes after the sale converges: a verification (or a lapse) makes stripe:reprice-subscriptions move the contract onto the other Price with PRORATE_NONE, because the term is already paid for. The module items follow the same way. - Downstream follows: the invoice total equals what was taken, the proof register expects the figure this customer is actually charged (so a correct reverse-charge sale is no longer flagged as a mismatch, and an overcharged one is), the setup fee obeys the same rule, and the booking page quotes what it will charge. - StripeClient gained activatePrice(). Archived Prices were brought back in our own table and left inactive at Stripe, so a rate that moved and moved back pointed the catalogue at a Price no checkout could be opened for. An unverified number is still charged the gross — an unchecked string must never be a discount — and where the net Price is missing the checkout refuses rather than reaching for the domestic one.

nexxo	f02e86769b	Charge the price the website shows, and hand a withdrawal back in full ... Stripe was charging the catalogue's NET figure while the document added the domestic rate on top: a customer quoted 214,80 paid 179,00 and was then invoiced for VAT nobody had collected. Under para 11(12) UStG that VAT is owed to the tax office whether or not it ever arrived, so every document issued created a liability against revenue that did not contain it. The Stripe Price now carries the GROSS figure. price_cents stays net - it is frozen onto every contract and PlanChange prorates against it, so redefining it would corrupt every pro-rata sum ever computed. Only the amount at the till moved, and it is formed by the one call TaxTreatment already answers for the price sheet and for the invoice, so displayed, charged and invoiced cannot drift apart. Stripe's automatic_tax is deliberately not used. TaxTreatment is the single tax authority here, and a second rate computed by Stripe would take 19 % from a German consumer while our document said 20 %. A Stripe Price cannot be edited, so a changed figure means a new Price and the old one archived - which stops it being SOLD and leaves every subscription already on it billing the old amount for ever. stripe:reprice-subscriptions is the second half, and a command of its own because it touches live money. A withdrawing consumer is refunded in full, as the owner decided. That is more generous than FAGG para 16 requires, and it makes the express-request consent the statute hinges on irrelevant - so the gate is gone rather than left looking load-bearing.

nexxo	8f1630ba91	Bill a booked module every month, and put it on the invoice ... A module was never an item on the Stripe subscription, so it was charged in the month it was booked and never again. And the renewal document was written from our own contract snapshot, so it would not have said so even if the money had been taken. Two halves of one fault, closed together. Modules are items now. stripe:sync-catalogue mirrors a Product and a Price per module on both terms — a Stripe Price carries its own interval, and a booking frozen at an older figure needs its own Price, so they are keyed by module, amount, currency and interval in stripe_addon_prices. Booking adds an item with always_invoice: prorated by days AND charged there and then, which is the invoice the owner wants for a module booked mid-term. A second storage pack is a quantity on one item, not a second item. Cancelling takes the item off with no proration — no credit, and the next cycle is simply smaller — while the module itself is kept until the period end on subscription_addons.cancels_at and ended by clupilot:end-cancelled-addons. Documents are built from Stripe's own invoice lines. Stripe is what charged the customer; a document assembled from our figures would state a sum that is not the one taken. So every paid Stripe invoice gets one document with one number, idempotent on stripe_invoice_id — a cycle carrying package and every module together, a mid-period booking carrying just its prorated line, an upgrade carrying its proration. Only the wording is ours: each line is named from the catalogue rather than printed as a Price id, and a line nobody can name stays on the document under Stripe's own description and is logged. The checkout's own invoice is still the one exception; that purchase already has a document. Stripe being away never undoes a booking that has already reached the machine. The failure is parked on the contract in stripe_addon_sync and swept by the same clupilot:sync-stripe-subscriptions that retries a plan change, which finds its work from the bookings themselves rather than from the marker. A granted contract has no Stripe subscription and is not touched at all. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>	2026-07-29 20:22:02 +02:00
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. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>	2026-07-26 13:36:28 +02:00
