fix(payments): refuse to book a bank row that unlinked vouchers already explain (#2300)
* fix(payments): refuse to book a bank row that unlinked vouchers already explain A bank feed can deliver several affarshandelser as one row (a Bankgirot daily aggregate: two customers' invoices, one "BGGIRERING" row with no payer). When each invoice was already marked paid by hand, nothing on the account equals the row, the 1:1 duplicate check passes, and "Dela betalning" books the money a second time against whatever open invoices the user picks (the next period's identical ones, in the reported case). - lib/reconciliation/covering-set.ts: exact ore subset sum over a capped candidate list, smallest set first, closest in date second. - detectExplainingVoucherSet(+ForTransaction): the vouchers whose bank legs on the row's settlement account, in the row's direction, within 7 days, add up exactly to the row; linked through any of the three anchors drops a voucher, a payment row without a bank transaction keeps it. - POST match-batch refuses with BATCH_TX_POSSIBLE_DUPLICATE and returns the set; force=true must echo expected_journal_entry_ids (same binding as the single door). Fails open on a detection error. - GET duplicate-payment-check returns candidate_set next to candidate. - MatchAllocationDialog: pre-flight panel with the vouchers, one click links the row to them through the existing 1:1 or 1:N bank link (no new voucher), "Bokfor anda" acknowledges the set; confirm is disabled until then. Invoices dated after the bank row get a hint badge. - Mark-paid guard: aggregate sweep (row = this invoice + an exact subset of other open invoices, 7 days, kronor) when the name sweeps found nothing; PaymentBookingDialog shows the covered invoice numbers and points to the split under Transaktioner. Follow-ups: #2293 (1:N proposals in the auto-matcher), #2294 (MCP staging guard), #2299 (supplier-side text guard). Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01NyjeEi1U8vnuPT4QXgayXu * test(invoices): account for the aggregate sweep in the mark-paid route queue The sweep issues one more transactions query whenever the name probes come back empty, so every queued-mock sequence that reaches it gains a slot. The sweep itself now fails open on odd client shapes (a single object for a list query) and on errors: an advisory guard must never block "Markera som betald". Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01NyjeEi1U8vnuPT4QXgayXu * fix(payments): fail open on resolved query errors; aggregate sweep without a payer name Review follow-ups on #2300. A PostgREST failure resolves with { data: null, error } instead of throwing, so the set detector read a failed link lookup as "no links" and a failed cash-account lookup as "scan every 19xx account"; both now return null (the booking RPC keeps the last word). The aggregate sweep never needed a customer name (a Bankgirot row names nobody), so a nameless invoice goes straight to it instead of skipping the guard. The already-booked panel is announced as a live region, and the "also covers" string is plural-aware.

[2026-09-04] company_settings.pays_salaries (and a never-attested employer_registered) now follow the ledger: trigger salary_runs_booked_marks_employer (20260904191000) sets them when a salary run is booked, with a backfill for the 12 companies already booking payroll with the flag at its default. Support case 2026-09-04: the assistant told a payroll-running aktiebolag in every answer that it "betalar inte löner" because lib/agent/ask/snapshot.ts asserted the column default (NOT NULL DEFAULT false, only written by the Skatt settings form) as a fact. The snapshot and the composer's KÄNDA FAKTA now apply the employee-facts doctrine (positive evidence or an attested negative, never the default) and the snapshot names Inställningar > Skatt / > Bokföring so the model can point at the page. Chose a trigger over calling a helper from the booking code because there are three booking writers (lib/salary/book-run.ts, the v1 route's own copy, seeders) and 20260717151000 already treated in-app payroll as employer evidence once as a one-off backfill; the trigger makes that rule continuous. An explicit employer_registered = false stays the user's answer.

[2026-09-04] Supplier credit notes rest at 'credited' from creation (one row builder in lib/supplier-invoices/credit-note.ts for the dashboard route, the MCP executor and the v1 API) and a CHECK (supplier_invoices_credit_note_not_payable, 20260904190000) keeps every writer out of the payable states; the worklist attest count also excludes is_credit_note. Support case 2026-09-04: a credit note was inserted at 'registered' (the attest entry state) while the detail page rightly had no attest button for it, so Att göra showed "1 leverantörsfaktura att attestera" that nobody could clear; 14 such rows on prod plus one MCP-approved credit note, all backfilled by the migration (one immutable reset-source row skipped, hence NOT VALID). Chose the DB CHECK over fixing only the three insert literals because the invariant is "a credit note is never a payable", not "this literal says registered"; chose 'credited' over 'approved'+approved_at (would surface Markera betald and the Att betala tab) and over 'paid' (the customer side forbids paid credit notes by CHECK); the provider importers already used 'credited'. Also: the GET route now hydrates credited_original with a second scoped query because PostgREST cannot pick a direction for a self-referencing embed hint and returned the one-to-many side (an empty array), rendered as "Krediterar: Ankomst #" with no number.

[2026-09-04] Underlag attach on a folder-picked Fortnox export (Loftux, 50 of 50 files refused with UNDERLAG_REF_MISMATCH): the multipart filename is reduced to its basename at the route boundary (lib/documents/upload-file-name.ts), rather than teaching the voucher-ref parser to strip directories or adding a client-supplied file_name field. Chrome writes webkitRelativePath as the multipart filename for folder selections, so the attach check saw "2026/06/Leverantörsfakturor/A166_x.pdf" while the preview had resolved File.name "A166_x.pdf"; the two endpoints received the same file under two names and the guard compared them. Stripping inside the parser would turn a typed manual ref "2024/01/31" into voucher 31 (the manual box shares the parser), and a second client-supplied name is no more trustworthy than the first, so the boundary is the only level that fixes the class.
|
||||
[2026-09-04] Bankgirot aggregate double booking (Discord, gecko): the fix generalises the existing 1:1 "already booked" check to a SET of unlinked vouchers (exact öre sum, same account, same direction, ±7 days) and runs it at the two doors that could book the money a second time, instead of blocking "Markera som betald" for bank-connected companies or teaching the batch RPC about vouchers. Rejected: a bank-feed gate on mark-paid (payments outside the feed are legitimate and Fortnox keeps both doors), a name-tokenised text guard (the rows this exists for, "BGGIRERING 03447786", carry no payer at all), and storno-then-rebook as the remedy (the mark-paid vouchers are correct bookkeeping; the truthful representation is one bank row linked to two vouchers, which linkTransactionToVouchers already supports). match-batch now refuses with BATCH_TX_POSSIBLE_DUPLICATE unless force=true echoes the detected ids (same binding as the single door); the dialog links the row to the vouchers through the existing 1:N link. The invoice-side guard gained an aggregate sweep (row = this invoice + an exact subset of other open invoices, ±7 days, kronor only) that runs only when the name sweeps found nothing, so one warning is enough and no extra queries hit the common path. Not folded in: 1:N proposals in the reconciliation auto-matcher and the MCP batch staging (follow-up issues).

[2026-09-04] Sandbox seed recovery (#2292) uses a per-anonymous-user database claim and a completion marker written last. A failed or expired attempt archives its exclusively owned demo company and starts a fresh one, preserving partial posted history for normal sandbox expiry instead of reseeding into it. Legacy demos are adopted only when the final payroll links prove completion. All demo vouchers now use the bookkeeping engine; the posting-integrity guards stay unchanged.

[2026-09-04] Migrated sales invoices without rows (Profilio 384/384, Loftux 311/672, Damac 182/542, Clearstoq 1 125/1 125): completed by an hourly re-runnable pass (extensions/general/arcim-migration/lib/complete-invoice-lines.ts, cron /api/extensions/arcim-migration/complete-invoice-lines/cron) that starts from OUR row-less invoices, joins them to the provider register on number + date, hydrates only that subset and writes rows once the detail total matches the stored total to the öre; the header VAT split is rewritten only when the stored one holds no evidence (null rate, or 0 kr VAT beside subtotal = total). Why not a bigger in-run budget: the largest register (1 911 invoices at Fortnox's platform-wide 4 req/s) does not fit one 300 s function whatever the split, and a budget-bounded one-shot pass leaves whatever it misses missing forever, silently (the wizard never showed the hydration report; it does now). Why not re-running fetchSalesInvoicesHydrated: it sorts the whole register open-first every time, so a second run re-spends its budget on the same invoices and never reaches the rest. Why not reset + re-import or an arithmetic backfill: reset deletes rows that payments and vouchers already point at, and total/1,25 asserts a rate the source never stated (DECISIONS 2026-08-22). The pass reuses mapSalesInvoice, so a row it writes is indistinguishable from a fully hydrated import; it never touches totals, status, payments or any journal entry (momsdeklaration and every report read the ledger).
|
||||
[2026-09-04] Connector-hop failures (timeout, error envelope, wire-contract mismatch) are transient in every sync path: the row keeps its status and the user message says no renewal is needed, same as AspspUnavailableError (#2202), and the cron now treats AspspUnavailableError the same way instead of parking it in 'error'. Why: on 2026-09-04 the Connect service answered a shape the client rejects and the cron flipped four canary companies to 'error' with SYNC_FAILED_MESSAGE, so users re-authorized consents that were fine. The Zod issues are logged (field paths) because a bare 'unexpected shape' left the failure undiagnosable. Rejected: a new 'degraded' connection status (one more state every filter and the probe would have to learn; the health probe already catches a dead session on the same run) and removing the canary companies from the env (hides the contract bug instead of exposing its field paths).

|

*
|

* Why this exists: a bank feed can deliver several affärshändelser as ONE row
|
||||
* (a Bankgirot daily aggregate, a lump payout), and each of them may already
|
||||
* be booked on its own (an invoice marked paid by hand, a salary voucher per
|
||||
* employee). The 1:1 duplicate check then sees no voucher of the row's amount
|
||||
* and stays silent, while the row is fully explained by two or three vouchers
|
||||
* that carry no bank link. The exact sum is a deterministic signal that needs
|
||||
* no counterparty text, which is what bank rows like "BGGIRERING 03447786"
|
||||
* never carry.
|
||||
*
|
||||
* Pure and client-safe on purpose: the same search can rank a suggestion in
|
||||
* the reconciliation view or guard a booking route without dragging server
|
||||
* dependencies into a component.
|
||||
*
|
||||
* Search order is smallest set first (one voucher beats two), and within one
|
||||
* size the set closest in date to the bank row. The candidate list is capped
|
||||
* before the search so a busy account cannot make the combinatorics
|
||||
* unbounded: with 40 candidates and sets of at most 4 the worst case is under
|
||||
* a hundred thousand partial sums, which is well below a millisecond of work.
