nexxo	ab4b0311d4	Copy every invoice to the archive when it is issued, and notice when that fails ... The application knows nothing about NFS and should not. It writes to a directory; whether that is a local disk, a bind mount or a NAS over NFS 4.1 belongs to the mount. No protocol library, the target changes without code changing with it, and the whole thing is testable against a temp directory. The finding that shaped it: mkdir -p on a path whose mount is NOT there succeeds. It creates the empty directory beneath the mountpoint, writes the invoice onto the container's own disk and reports success — so an unmounted NAS would quietly collect invoices locally while every check said it worked. An archive that silently is not the archive is worse than none. The root is therefore never created, only used: a missing root means a missing mount, and that is a failure. Only the year subdirectory is created, inside a root already proven to exist. Written to a .part and renamed. A rename within one filesystem is atomic, so whatever watches that folder never sees a truncated PDF and takes it for a finished invoice. The size is read back afterwards rather than the write being trusted: over a network mount a short write can report success, and an archive of truncated files looks exactly like one that worked. Queued, not done during the request. A network mount can block for its whole timeout, and an invoice must not fail to be issued because a NAS is rebooting. Dispatched after the commit, or a worker could look for an invoice that has not landed yet. And copy-on-issue is not enough on its own: an invoice issued while the office connection was down never arrives, the queue eventually gives up, and nobody opens an archive to check whether last Tuesday is in it. An hourly sweep re-queues whatever is still missing, the failure is recorded on the invoice rather than only in a log, and the Finance page says how many are outstanding.

nexxo	735daf46a4	Lay the foundation for self-issued invoices: series, numbers, frozen documents ... An invoice is a tax document, so two things drive the shape of this. It is frozen at issue. Everything the finished document says — issuer address, VAT number, bank details, customer address, every line, the rate, the totals — is copied into the invoice row when the number is assigned. The PDF is rendered from that and never stored, which is what was asked for; rendering it from today's settings instead would have been simpler and wrong, because an address changed in 2028 would rewrite an invoice from 2026. The width of this table IS the feature. Numbers are gapless and ascending, which is a legal requirement rather than a preference, and that is why none of it is derived from the invoices table. "Highest number plus one" hands the same number to two sales that land together and hands a used number back out after a row is removed — a number already printed on a document somebody holds. The counter is a column, read and advanced under a row lock inside the caller's transaction, and taking one outside a transaction throws rather than quietly working. Four Rechnungskreise seeded — Rechnung, Gutschrift, Storno, Anzahlung — each with its own prefix and its own counter, because a credit note is not an invoice with a minus sign in front of it. Seeded rather than left to the operator: an installation with no series cannot issue anything, and discovering that at the first sale is the worst possible moment. TCPDF added, for the renderer that comes next. There is deliberately no test for the outside-a-transaction guard, and a note where it would have been: RefreshDatabase opens a transaction around every test, so the guard cannot fire and a green test for it would be green for a reason that has nothing to do with the guard.
