* feat(mcp): already-explained voucher guard at stage and commit for match_batch_allocate

The dashboard match-batch route refused BATCH_TX_POSSIBLE_DUPLICATE when
posted, unlinked vouchers already summed to the bank row (PR #2300), but the
MCP door (gnubok_match_batch_allocate staging + commitMatchBatchAllocate)
called the RPC with no guard, so an agent could book a Bankgirot aggregate a
second time. The detector existed once; the guard lived in one door.

One shared decision helper, lib/invoices/already-explained-guard.ts, now
sits on top of the existing detectors (no fork) and is called by the
dashboard route, the MCP staging tools and the commit executors:

- gnubok_match_batch_allocate refuses to stage, coded
  BATCH_TX_POSSIBLE_DUPLICATE, naming the vouchers, the reconcile_match /
  link_transaction_to_journal_entry call that resolves the row, and the
  exact force + expected_journal_entry_ids binding.
- commitMatchBatchAllocate runs the same guard before the RPC and
  re-validates a staged force binding against the set detected at commit,
  so a stale approval cannot book a duplicate; 409 auto-rejects with the
  vouchers in result_data.
- force + expected_journal_entry_ids on the tool mirror MatchBatchSchema;
  an honoured override stages with a compliance_warning and, after the
  booking succeeds, writes BankTransactionDuplicateDismissed to
  behandlingshistorik (dashboard route included; it only logged before).
- gnubok_match_transaction_to_invoice and commitMatchTransactionInvoice get
  the dashboard's 1:1 soft-duplicate guard (MATCH_INVOICE_POSSIBLE_DUPLICATE
  / MATCH_INVOICE_FORCE_CANDIDATE_MISMATCH) with force +
  expected_journal_entry_id; at commit it runs before the storno.
- Registry: both duplicate codes gain retryable: false and a remediation.

Catalog payload held under the 60K ceiling by trimming the two tools' own
descriptions (59 988 measured, ledger entry in payload-size.bench.test.ts).

* fix(mcp): refuse an unverifiable forced override, surface a failed duplicate check, validate the binding (#2294 review)

Review round on PR #2346 (CodeRabbit + compliance):

- guardAlreadyExplained returned 'clear' when the detector threw even with
  force=true, so a forced 1:N override could book without re-validating
  expected_journal_entry_ids and left no behandlingshistorik record. It now
  returns a distinct 'unverifiable' outcome under force (mirrors
  guardDuplicatePaymentVoucher); the dashboard route, the MCP staging tool
  and the commit executor all refuse it with the new registry code
  BATCH_TX_EXPLAINED_CHECK_FAILED (409, retryable, remediation). Regression
  tests on every caller.
- A detector failure without force still fails open at stage time, but no
  longer silently: the tools track onDetectError and stage a
  complianceNote, so preview_data.compliance_warning is set on both
  match_batch_allocate (GenericPreview renders it) and
  match_transaction_invoice (MatchTransactionInvoicePreview now renders
  data.compliance_warning through AttnLine).
- expected_journal_entry_ids / expected_journal_entry_id are validated at
  the MCP boundary (array of 1 to 10 non-empty strings / non-empty string)
  and refused with VALIDATION_ERROR instead of being silently filtered.
  No schema description text added: catalog payload unchanged.
- RoPA: .compliance/ropa.yaml gains bookkeeping.duplicate_dismissal_history
  for the BankTransactionDuplicateDismissed record (Art. 6(1)(c), BFNAR
  2013:2 p. 9.16, retention per BFL 7 kap, stored in processing_history).

287828a850 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).

* 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".

* 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.

MattssonandClaude Fable 5.1 1c82baf553 feat(invoices): offert (quote) document type with own OF-series, decisions, conversion, MCP and v1 (#2163)
* fix(invoices): reminders, AR ledger, AR reconciliation and deadlines only read fakturor

The overdue-reminder run, the kundreskontra, the 1510 reconciliation and the
deadlines page selected invoices by status alone. A sent proforma past its
due date was chased with a betalningspaminnelse and flipped to 'overdue',
and it appeared as a receivable. All four now filter document_type =
'invoice', which is also the precondition for adding quotes (offert): a
quote carries a date but never a receivable.

Claude-Session: https://claude.ai/code/session_01W45yD8NfQ97JhyYaXpzN56

* feat(invoices): offert (quote) document type with its own OF-series, decisions and conversion

Adds document_type 'quote' with valid_until, quote_status (open / accepted /
declined; expired is derived from valid_until, never stored) and
quote_decided_at. Quotes are numbered OF-nnn at insert from
company_settings.next_quote_number via generate_quote_number(), the same
pattern as delivery notes, so a declined quote never leaves a hole in the
F-series the way a proforma does. The column next_quote_number already
existed on prod and staging without a migration; the migration adopts it.

Engine: build-invoice-write writes the quote columns and keeps
remaining_amount at 0; the draft editor refuses accepted or declined
quotes; PATCH refuses changing a quote's or delivery note's document type
since the number belongs to the series; mark-paid refuses quotes.

New POST /api/invoices/[id]/quote-status records the decision and locks
once an invoice exists. Conversion is extracted into
lib/invoices/convert-to-invoice.ts (one implementation for the route and
the MCP staged commit, which had drifted): a converted quote stays and
flips to accepted, the invoice links back via converted_from_id and gets
its due date from the customer's payment terms; a declined or already
invoiced quote is refused. next-number previews the OF-series for quotes.

Migration applied to the staging branch and registered as 20260902140000;
the pg test runs in CI (pg-real).

* feat(invoices): quote PDF, email and filename surfaces

The customer-facing surfaces get a quote sibling for every proforma branch:
PDF title OFFERT / QUOTE with Offertdatum and Giltig till instead of the
due date, a notice that the document is not an invoice or a payment
request, and no payment box, OCR, bankgiro, Swish, QR or payment link.
The email says the quote is attached and valid until the expiry, drops
the payment details and pay-online button, and asks about the quote
rather than the invoice. Filenames read "Offert nr OF-001". Seller VAT
number and payment accounts are skipped for quotes as for proformas:
a quote is not a faktura under ML 17 kap.

Claude-Session: https://claude.ai/code/session_01W45yD8NfQ97JhyYaXpzN56

* feat(invoices): offert in the editor, list and detail pages

Editor: "Offert" document type with a required "Giltig till" field
(default today + 30 days) in place of the due date; the wire body mirrors
it into due_date so the shared schema is satisfied. Payment link, ROT/RUT,
periodisering and the bank box are already gated on real invoices. The
type cannot be switched on an existing quote (its OF-number belongs to
the series).

List: an Offerter tab beside Proforma, "Ny offert" in the split button,
and a status column that shows the decision or the derived expiry:
Utgången and Avböjd are exception chips, Öppen and Accepterad muted text.

Detail: Acceptera and Skapa faktura in the header, Avböj in the overflow
menu; an expired quote asks before accepting or invoicing (bypassable);
once an invoice exists the page links to it as Fakturerad and hides the
decision actions. Strings in both sv and en.

* feat(mcp,v1): expose offert on the MCP tools and the v1 REST surface

MCP: create_invoice takes document_type quote with a required valid_until
and allocates the OF-number at insert; the convert tool keeps its id and
accepts quotes with the registry refusal codes; new set_quote_status;
list_invoices and get_invoice expose valid_until and the effective quote
status, including a derived expired filter. The tools/list payload stays
under its ceiling without a ledger change. The MCP staged convert now
uses the shared converter.

v1: POST /invoices/{id}/quote-status (registered in the endpoint registry,
scope map and route loader), valid_until and quote_status in the list,
create and detail shapes, and a quote_status list filter. Skill atoms
mention offert. Decision log lines for the own number series, derived
expiry, accepted-not-cancelled conversion and the header action layout.

* fix(invoices): close the quote review findings in one pass

Skeptics (correctness, compliance, regression) and CodeRabbit on #2163:

- quote_status is no longer a write-builder output, so a v1 PATCH or MCP
  update_invoice can never reset a recorded accept/decline; new quotes are
  opened by the invoices_quote_defaults trigger (20260902141000), which
  also keeps due_date and valid_until equal. v1 PATCH and the MCP update
  executor now use the shared editable-draft predicate.
- One live invoice per converted source, enforced by a partial unique
  index; the converter maps 23505 to INVOICE_QUOTE_ALREADY_INVOICED and
  both quote-status routes compare-and-set on the decision they read.
- MCP-created quotes carry remaining_amount 0; mark-paid, transaction
  match and voucher link refuse non-invoices on the MCP staging tools,
  the executors and the dashboard link route.
- Conversion of a foreign-currency source refetches the rate for the
  conversion day (ML 8 kap 21-23 paragraphs) and fails closed without one;
  0-day payment terms mean due on receipt.
- bulk-create refuses quotes per item; list_invoices rejects a
  quote_status filter combined with another document_type; an omitted
  document_type on PATCH means unchanged.
- attention, push notifications, open-AR count, FX revaluation, year-end
  and accrual auto-detect and bank-match suggestions only read fakturor.
- Quote PDF and email print Summa / Total instead of Att betala.
- Regenerated skills/accounted-api for the new v1 endpoint.

Declined with reasons in DECISIONS.md: NOT VALID + VALIDATE and CONCURRENTLY
on the migrations (repo precedent, 13.8k rows, transactional apply);
re-validating VAT treatment at conversion (the converted invoice is a
draft the user reviews; follow-up).

* fix(invoices): second review round: migration versions, order links, batch allocation, races

- Migrations renamed to 20260902220000 / 20260902221000: #2166 shipped its
  own 20260902141000 to prod while this PR was in review and prod's head
  moved past both files; below-head versions are skipped by branching,
  which would have left the quote trigger off prod. Staging rows renamed.
- Quote lines never carry sales_order_item_id (an offer must not count as
  invoiced kundorder quantity); the converter carries a proforma line's
  order link onto the invoice.
- Converter compare-and-sets the source (proforma cancel, quote accept):
  a concurrent cancel, proforma-to-order conversion or decision removes
  the orphan invoice with INVOICE_CONVERT_SOURCE_CHANGED instead of a
  second document for the same sale.
- MCP set_quote_status gets the same compare-and-set as the HTTP routes;
  0-row updates report INVOICE_QUOTE_CHANGED_CONCURRENTLY everywhere.
  quote-status (dashboard, v1, MCP) accepts valid_until so an expired
  sent quote can be reopened, as the docs promised.
- MCP mark-paid refuses only quotes, parity with the dashboard route
  (a sent proforma marked paid is a supported prepayment record).
- Batch allocation (dashboard route and MCP tool) refuses non-invoices
  before the RPC, which gates on status alone.
- Customer AR drill-down, v1 customer open invoices and archive guard,
  and the calendar feed read fakturor only.
- Draft quote PDF says "UTKAST" instead of "not a valid invoice"; the
  editor locks the document type on existing quotes and delivery notes.

Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
Claude-Session: https://claude.ai/code/session_0111fYAUxKtpxU1BHiBioqzs

* fix(invoices): third review round: atomic decision lock, viewer gate, lookup errors, quote payment terms

- 20260902222000: BEFORE UPDATE trigger locks an accepted quote while a
  live converted invoice exists (the compare-and-set in the three decision
  writers could still be beaten by a conversion landing in between); the
  routes and the MCP tool map the raise to 409 INVOICE_QUOTE_ALREADY_INVOICED.
  generate_quote_number now also requires a non-viewer membership so a
  viewer's session token cannot burn OF-numbers through PostgREST.
- Converter checks quote eligibility before the Riksbanken call and treats
  a failed company_settings read as a failure instead of a 30-day default.
- Re-sending the same decision keeps quote_decided_at (idempotent).
- gnubok_find_voucher_candidates_for_invoice refuses non-invoices like its
  write sibling; the dashboard link route surfaces a failed lookup.
- Late-fee and credit-term texts never print on a quote.
Applied and registered on staging; pg tests added.

* fix(invoices): review nits: fail-closed batch lookup, dry-run expiry, quote heading, quote-date CHECK

- match-batch surfaces a failed document lookup instead of allocating.
- v1 quote-status dry-run preview carries the new valid_until.
- Quote PDF heading reads Offertinformation / Quote information.
- 20260902222000 also pins the date invariants the trigger maintains as a
  CHECK: a quote always has valid_until = due_date, nothing else has one.
  Applied on staging.

Jakob WennbergandClaude Opus 5 27ae59040e fix(transactions): retire stale invoice match pointers when an invoice settles (#1313)
* fix(transactions): retire stale invoice match pointers when an invoice settles

potential_invoice_id / potential_supplier_invoice_id are write-once import
suggestions: nothing revisited them once written. With recurring same-amount
invoices, an earlier suggestion pointed transaction A at invoice X, X was then
paid off by transaction B, and A kept pointing at a fully paid invoice. The
match dialog computed its amount diff against that invoice's 0 kr
remaining_amount and reported a bogus partial payment, and the dead pointer
also blocked a fresh suggestion: both re-suggestion scans require the column
to be NULL.

Add one shared helper, clearSettledInvoiceSuggestions(), that nulls a settled
invoice's own suggestion column on every other transaction of the same
company, scoped by company_id and by that invoice id only, never widening to
the confirmed invoice_id / supplier_invoice_id links. It is best effort by
construction: every caller has already booked a payment verifikat, so a failed
cleanup logs and returns instead of failing the settle.

Wired into every path where an invoice reaches paid through a payment:
the dashboard and v1 match-invoice / match-supplier-invoice routes, the
dashboard and v1 mark-paid routes, settleInvoicePayment, the batch allocation
route (per fully settled allocation), linkInvoiceToVoucher and
linkSupplierInvoiceToVoucher, linkTransactionToJournalEntry, and the MCP
staged-operation executors for mark_invoice_paid and
match_transaction_invoice. Partial payments are deliberately left alone: a
partially paid invoice is still matchable. The v1 supplier match route also
clears its own row's hint, which it was missing next to its dashboard twin.

Read-time revalidation stays as the backstop for the paths not wired up here.
countSuggestedMatches now delegates to listSuggestedMatches, which already
revalidates candidates, so the worklist badge can no longer claim a number the
list refuses to render.

A data-only backfill migration retires the pointers already stranded in the
database. It touches no journal entry, verifikat or period-locked data, is
idempotent, and its status lists mirror lib/invoices/matchable-statuses.ts.

Fixes #1259

Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

* fix(transactions): wire the MCP batch allocation into the settled-pointer cleanup

Review follow-up on the #1259 fix.

commitMatchBatchAllocate calls the same match_batch_allocate RPC as the
dashboard route, and gnubok_match_batch_allocate is a live staged MCP tool, so
an agent settling a samlingsbetalning reproduced the issue exactly: the RPC
nulls potential_invoice_id / potential_supplier_invoice_id only on the source
transaction, leaving every other transaction of the company pointing at an
invoice the batch just closed. The per-allocation loop moves into
clearSettledBatchAllocationSuggestions() so the HTTP route and the MCP executor
run the same code and cannot drift again, with a commit-path test pinning that
only the fully settled allocation is retired.

The enlarged badge scan is made safe. countSuggestedMatches now feeds up to 200
ids into listSuggestedMatches, past the 150 per .in() that countInboxDocuments
already chunks for, so the candidate lookups are chunked at IN_CLAUSE_CHUNK too
and their ids deduped. Both lookups now check .error: previously a 414, a 500 or
an RLS change produced empty maps, an empty list and a zero badge with nothing
logged. Every failure branch here logs companyId, matching the logAndZero
convention.

Also: restore the anchorSupplierInvoiceDocument doc comment above its own call
in the dashboard supplier-invoice mark-paid route (the #1259 block had been
inserted between them), and assert the transaction update payload in the v1
match-supplier-invoice test, which now covers the potential_supplier_invoice_id
null that the route was missing next to its dashboard twin.

Fixes #1259

Jakob WennbergandClaude Sonnet 5 ec27228a8e style: remove em/en dashes repo-wide, add CLAUDE.md rule against them (#890)
Em dashes (—) and en dashes (–) had spread across comments, docs, tests,
and a few UI strings, reading as AI-generated boilerplate rather than
house style. Replaced each with punctuation matching its context: colon
for explanatory clauses, comma for asides, plain hyphen for numeric/legal
ranges (e.g. "21-23§"), "to"/"till" for date ranges, parentheses for
paired-dash asides. messages/en.json and messages/sv.json were fixed by
hand together to keep sv/en in sync.

Left untouched where the dash is the functional subject rather than
decorative punctuation: date-range-parser.ts's separator regex,
charset-repair.ts's CP1252 byte-mapping table (and its test), the SIE
encoding mojibake docs, generic-csv.ts's minus-sign normalizer, the
agent system-prompt files that already instruct against em dashes, and
a golden iXBRL test fixture compared byte-for-byte.

Also fixes two bugs surfaced along the way: an off-by-one in
ApiKeysPanel's scope-label split (a leftover from an earlier partial
pass), and a charset-repair test that had lost the literal en-dash it
exists to verify.

Regenerated the agent atom seed migration (skills:generate) since 27
SKILL.md files changed. Added a CLAUDE.md rule against em/en dashes,
with an explicit carve-out for the functional-dash cases above.

Jakob WennbergandClaude Opus 4.7 fc7a46c3f2 fix(match-batch): cross-currency allocations + widened tolerance (#607)
* fix(match-batch): cross-currency allocations + widened tolerance

Reported by jakob testing PR #603's MatchAllocationDialog with a SEK
bank tx + a mix of SEK and USD invoices:

1. Tally rendered "1 USD + 1 SEK = 2 kr" — summing different currencies
   as if they were the same.
2. The 0.005 SEK tolerance blocked confirm on any FX rounding delta.

## What changed

**UI (MatchAllocationDialog.tsx)**
- Per-row amount input is explicitly in TRANSACTION currency (SEK for a
  Swedish bank import). Cross-currency rows show an "≈ X.XX (invoice
  currency)" hint under the input so the user can verify the FX result.
- Default amount for a cross-currency allocation is
  `invoice.remaining × invoice.exchange_rate` (booked SEK), so the user
  doesn't have to mental-math the FX.
- Overshoot tolerance widened from 0.005 SEK to `max(1 SEK, 0.5% × tx)`
  so bank-side FX rounding doesn't block confirm. A 2 400 kr tx now
  accepts ~12 kr of tolerance, a 100 kkr transfer accepts 500 kr.

**RPC (match_batch_allocate cross_currency migration)**
- BATCH_CURRENCY_MISMATCH dropped per-allocation. Mixed currencies now
  accepted with the convention that the cross-currency row pays the
  FULL invoice remaining (matches the single-tx match-supplier-invoice
  behavior). Partial cross-currency is out of scope for v1.
- AR/AP line is booked at `invoice.remaining × invoice.exchange_rate`
  (the SEK that was originally on 1510/2440). FX residual is posted
  to 7960 (Valutakursförluster) or 3960 (Valutakursvinster) per BAS.
- Sign conventions per direction documented inline:
    Customer: bank > booked → Cr 3960 (gain); bank < booked → Dr 7960
    Supplier: bank < booked → Cr 3960 (gain); bank > booked → Dr 7960
- New BATCH_FX_RATE_MISSING when the cross-currency invoice has no
  exchange_rate on file (would otherwise silently book at 0).
- New BATCH_FX_DEVIATION_TOO_LARGE when the user-entered amount
  deviates more than 10% from booked SEK — catches typos like "140"
  (USD invoice currency) when they meant "1390" (SEK equivalent)
  without rejecting genuine rate-day FX movement.

RPC patched on remote via Supabase MCP. Same-currency path is
byte-identical to the previous behavior.

* fix(match-batch): PR review — strict sum, bank line = tx_abs, FX validation

Round-1 review fixes on the cross-currency batch allocation flow:

UI (MatchAllocationDialog):
- Tighten tolerance to 0.005 SEK so the "balanced ✓" indicator matches
  what the server will accept. The previous widened tolerance (max 1 SEK
  or 0.5% × tx) created a reconciliation gap where the JE's bank line
  could legitimately disagree with the actual bank receipt.
- Require balanced before confirm — undershoot is now a blocking state
  with an explicit warning, not a silent "leave unallocated".
- Cross-currency default no longer caps at remainingTxBudget. Capping a
  USD invoice's default to the leftover SEK budget could silently
  trigger BATCH_FX_DEVIATION_TOO_LARGE on submit. The user re-balances
  the other rows to fit.
- Add explicit FX-rate validation (bound check 0 < rate < 100000).
- When a cross-currency invoice has no usable exchange_rate on file,
  leave the amount blank and surface a warning instead of guessing.

RPC (match_batch_allocate):
- New code BATCH_AMOUNT_BELOW_TX. Strict sum check on both sides means
  the server can't be coaxed by a direct API caller into the same
  broken state the UI now blocks.
- Bank line credit/debit = v_tx_abs (the actual bank movement) instead
  of sum-of-allocations. Same value within rounding under the strict
  sum check, but it makes intent legible and lets per-row FX diff lines
  absorb rounding.
- Defense-in-depth company_id filter on all re-queries / UPDATEs in
  the line-build + payment-row passes.
- Drop the v_booked_sek-aliasing-for-invoice.total foot-gun. Use a
  dedicated v_inv_total var.
- Truncate invoice_number to 32 chars in line_description.

Tests:
- pg-real: cross-currency happy path (USD invoice paid by SEK tx with
  FX loss to 7960, bank line = tx_abs).
- pg-real: BATCH_AMOUNT_BELOW_TX rejection on undershoot.

* fix(match-batch): PR review round 2 - caller user_id verification + FX bound

Compliance-swarm + swedish-compliance findings on round 1:

- CC6.3 (HIGH): p_user_id was caller-supplied and written into
  journal_entries.user_id / payment-row user_id without verifying it
  equals auth.uid(). Membership covered the company; nothing covered
  the user attribution. Two-layer fix: explicit guard rejects when
  p_user_id <> auth.uid(), and all writes now resolve v_caller =
  auth.uid() directly so the guard cant be silently bypassed.
- A.8.28 (MED): server-side FX upper-bound (0 < rate < 100000) matches
  the UI. Previously RPC only checked > 0, allowing the UI guard to
  diverge.
- V1.2.5 (LOW): truncate v_tx.date when concatenated into
  line_description (defense alongside round 1s invoice_number trunc).
- Symmetry: populate supplier_invoice_payments.exchange_rate (column
  existed, INSERT omitted it). Customer side already populated. Matches
  swedish-compliances traceability note on AP rorelseskulder.

* fix(match-batch): PR review round 3 - drop p_user_id, CHECK constraints, payment-day rate

Genuine round-2 review findings (compliance-swarm + swedish-compliance):

- V4.5: p_user_id dropped from RPC signature entirely. Round-2 added a
  guard; this removes the attack surface at the API boundary. Caller is
  resolved via auth.uid() inside the function. Route updated.
- V2.2: CHECK constraint on invoices.exchange_rate and
  supplier_invoices.exchange_rate (0 < rate < 100000). Three layers now
  enforce the bound: schema, RPC, UI.
- swedish-compliance traceability gap: payment_exchange_rate column on
  both invoice_payments and supplier_invoice_payments. Populated as
  v_alloc_amount / v_inv_remaining for cross-currency rows so FX diffs
  are reconstructible from the payment record alone (BFL 7 kap
  behandlingshistorik). NULL for same-currency. The existing
  exchange_rate column continues to store the invoicing rate.
- CC6.1: extract isValidExchangeRate() to lib/utils.ts. UI's three
  inline bound checks now share one validator.
- Dead code: drop unused leftover_note i18n key (sv + en).

Tests:
- pg-real signature updated (4-arg -> 3-arg) across all 9 call sites.
- Added payment_exchange_rate assertion to cross-currency happy path
  (invoicing rate 10.0 stays, payment-day rate stored as 10.5).

Migration applied to remote.

* fix(test): missed 4th arg in BATCH_UNAUTHORIZED pg-real test

Round-3 dropped p_user_id from match_batch_allocate. The replace_all
caught the userId/companyId pattern but missed the BATCH_UNAUTHORIZED
test which uses outsiderId instead of userId. CI failed with
"bind message supplies 4 parameters, but prepared statement requires 3".

Jakob WennbergandClaude Opus 4.7 7eb8715417 feat(transactions): split-payment allocator — 1 tx → N invoices (#603)
* fix(category-mapping): use leaf BAS accounts instead of group codes

3900, 5800, 6200 are BAS gruppkonton (header codes) and shouldn't carry
postings. Switched the default mappings to the matching leaf accounts:

  - income_other:     3900 -> 3999 (Övriga rörelseintäkter)
  - expense_travel:   5800 -> 5890 (Övriga resekostnader)
  - expense_telecom:  6200 -> 6230 (Datakommunikation)

The fallback for income_other inside getCategoryAccountMapping was also
hardcoded to '3900'; updated to '3999' for consistency.

* feat(transactions): split-payment allocator — 1 tx → N invoices

Closes one of the two flows that motivated PR #602's foundation:
allocating a single bank transaction across multiple customer OR
multiple supplier invoices, with one combined verifikat
(samlingsverifikation per BFL 5 kap 6§ st 3).

## Backend (Phase 3a)

- **PL/pgSQL RPC** match_batch_allocate (~400 lines): locks the tx +
  each target invoice with SELECT … FOR UPDATE in id order, validates
  status/currency/remaining/direction before any write, builds the
  combined verifikat via commit_journal_entry (atomically assigns
  voucher_number + flips draft→posted), inserts N rows in
  invoice_payments or supplier_invoice_payments pointing at the same
  JE, advances paid_amount/remaining_amount/status per invoice. Returns
  { ok, journal_entry_id, voucher_number, allocations: [...] } on
  success or { ok: false, code, details } on guard failure. Mixed
  customer+supplier kinds are rejected (v1 scope).

- **Endpoint** POST /api/transactions/[id]/match-batch — thin wrapper
  around the RPC. Validates body via MatchBatchSchema (zod
  discriminatedUnion + superRefine to catch mixed-kinds at the schema
  layer). On RPC success, emits one invoice.match_confirmed or
  supplier_invoice.match_confirmed event per allocation so existing
  subscribers (reminders, automations, processing-history) keep
  working. Maps the structured RPC error envelope to
  errorResponseFromCode.

- **16 new BATCH_* error codes** (sv+en): BATCH_TX_NOT_FOUND,
  BATCH_TX_ALREADY_BOOKED, BATCH_OVERSHOOT, BATCH_AMOUNT_EXCEEDS_TX,
  BATCH_MIXED_KINDS_UNSUPPORTED, BATCH_DIRECTION_MISMATCH,
  BATCH_CURRENCY_MISMATCH, BATCH_PERIOD_LOCKED, BATCH_RPC_FAILED, etc.

## UI (Phase 5a)

- **MatchAllocationDialog** (components/transactions/) — direction-
  aware (positive tx → customer invoices, negative → supplier). Search
  + selectable list of open invoices. Per-row amount input with default
  = min(invoice.remaining, tx_remaining_budget). Live tally with
  green-check balanced state, red overshoot warning, gray leftover
  note. Confirm button disabled on overshoot. POSTs to /match-batch
  and on 200 triggers the same exit animation as single-tx match.

- **Inbox row** gains a second outline icon button (Split icon) next
  to the existing 1:1 match button, gated by the same
  showInvoiceMatchButton predicate. Tooltip explains the direction-
  aware split. Opens MatchAllocationDialog.

- **i18n** strings under tx_match_allocation namespace in sv.json
  and en.json (32 keys each).

## Tests

- tests/pg/match-batch-allocate.pg.test.ts — 5 pg-real tests covering
  combined verifikat shape, overshoot guard, already-booked tx,
  direction mismatch, mixed-kinds rejection.
- app/api/transactions/[id]/match-batch/__tests__/route.test.ts — 5
  unit tests covering schema validation, mixed-kinds, happy path,
  structured-error mapping, raw-error → BATCH_RPC_FAILED.

63 unit tests pass across the touched paths. The RPC migration was
already applied to remote in an earlier Phase 3a session (idempotent
CREATE OR REPLACE FUNCTION; the next replay is a no-op).

* fix(match-batch): PR #603 review round 1 + CI fixes

Closes both CI failures and the three real review findings.

## CI fixes

- **pg-real failure**: the RPC declared
  `v_journal_entry_id uuid := uuid_generate_v4()` which fails in the CI
  Postgres image (uuid-ossp extension is off). Switched to
  `gen_random_uuid()` — the codebase standard already used by
  supplier_invoices, invoice_inbox, etc.
- **core-only failure**: my earlier BAS leaf-account commit
  (3900→3999, 5800→5890, 6200→6230) didn't update the matching
  `lib/bookkeeping/__tests__/category-mapping.test.ts` expectations,
  and `getDefaultAccountForCategory`'s fallback for `income_*` was
  still hardcoded to '3900'. Updated both.

## Review findings (greptile)

- **P1 deadlock-stable locking** (`match_batch_allocate.sql:11`): the
  validation `FOR UPDATE` loop ran in caller-supplied array order. Two
  concurrent calls with overlapping invoice sets in opposite orders
  could deadlock and one would abort with `BATCH_RPC_FAILED`. Now
  all three loops (validate, build lines, advance invoices) iterate
  via `SELECT … FROM jsonb_array_elements(…) ORDER BY
  COALESCE(invoice_id, supplier_invoice_id)`, giving a stable global
  lock order regardless of how the caller ordered the JSON array.

- **P1 duplicate-allocation detection** (`match_batch_allocate.sql:163`):
  the same invoice_id listed twice would pass the per-row overshoot
  guard (both iterations read the original `remaining_amount`) and
  the write loop would insert two `invoice_payments` rows for the
  same invoice. Added a `v_seen_ids text[]` check in the validation
  loop and a new `BATCH_DUPLICATE_ALLOCATION` error code (sv + en).
  The dialog already prevents this UI-side via `if (prev[candidate.id]
  return prev` — the RPC guard is the defense-in-depth layer.

- **P2 zod `.positive()`** (`schemas.ts:544`): allocation amount was
  `nonNegativeAmount` (allowing 0), passing schema validation only to
  be rejected by the RPC with `BATCH_INVALID_AMOUNT`. Now
  `z.number().positive(…)` so 0-amount entries fail at the schema
  layer with a per-field path, cleaner 400.

- **P2 strict `> 0` direction check** (`MatchAllocationDialog.tsx:82`):
  used `amount >= 0` to pick customer-side, but a zero-amount tx would
  load customer candidates only to hit `BATCH_TX_ZERO_AMOUNT` at
  submit time after the user has filled in allocations. Switched to
  `> 0` so 0-amount tx never reaches the dialog at all (it's rejected
  by the RPC immediately).

The fourth Greptile comment (the schema P2 about amount validation)
overlaps with the third; addressed in the same edit.

## Verification

- 112 unit tests pass across touched paths
- ESLint clean
- New pg-real test `tests/pg/match-batch-allocate.pg.test.ts` covers
  the dedupe scenario (same supplier invoice listed twice with summing
  amounts that individually pass per-row overshoot)
- RPC patch applied to remote via Supabase MCP

* fix(match-batch): PR #603 review round 2 — compliance hardening

Addresses the actionable findings from compliance-swarm and
Swedish-accounting-compliance reviews. Six small RPC changes + two
TS-side guards, all bundled in one follow-up migration.

## Security

- **(GDPR Art.5(1)(f) / ISO A.8.2) Caller verification**: SECURITY
  DEFINER bypasses RLS, and the prior RPC accepted any
  (p_user_id, p_company_id) pair from the route. Now the function
  rejects with new `BATCH_UNAUTHORIZED` (sv+en, HTTP 403) if
  `auth.uid()` is not a member of `p_company_id`. Pattern lifted from
  `harden_invoice_number_rpcs` (#20260510140000).
- **(OWASP V4.2) Allocation cap**: `MatchBatchSchema.allocations` now
  carries `.max(100)` to prevent DoS via unbounded FOR UPDATE locks.

## Swedish accounting correctness

- **source_type per direction**: was hardcoded to `'invoice_paid'` for
  both customer + supplier batches, mis-routing behandlingshistorik
  filters. Customer batches keep `'invoice_paid'`, supplier batches now
  write `'supplier_invoice_paid'`.
- **Fiscal-period determinism**: `LIMIT 1` on the period lookup was
  non-deterministic on overlap (e.g. corrected broken year). Added
  `ORDER BY period_start DESC` so the most recent matching period
  wins.
- **Tolerance harmonisation**: cross-allocation sum used `+0.01`
  tolerance while per-row used `+0.005`. Both now `+0.005` so a
  multi-row batch can't drift ~0.01 SEK while each row passes
  individually.
- **`transactions.category` no longer overwritten**: was forced to
  `'income_services'` (→ BAS 3001 at 25% VAT) for any customer batch,
  misrepresenting reduced-rate / export / EU-service invoices. The
  category is only meaningful 1:1 with a single invoice; batches now
  leave it as-is, mirroring the supplier-side `ELSE category` branch.

## Tests

- `tests/pg/match-batch-allocate.pg.test.ts` now wraps every RPC call
  in `withUserContext(userId)` so `auth.uid()` resolves to the seeded
  owner. Without this the new membership check would have failed all
  existing tests.
- New pg-real test: `rejects with BATCH_UNAUTHORIZED when caller is
  not a member of the company` — outsider user gets explicit refusal.
- New happy-path assertion: `source_type = 'supplier_invoice_paid'`
  on the combined verifikat for supplier batches.

15 unit tests pass on the touched paths. RPC patch applied to remote
via Supabase MCP. Out-of-scope mcp-server changes still parked locally.

Skipped findings (documented in PR comment thread):
  - V8.2.1 ownership pre-check at route layer (RPC enforces it)
  - V4.5 / Art.5(1)(b) narrower API response and event payload —
    typed contracts require the full shapes
  - V2.4 rate-limiting — system-level, applies to all match endpoints
  - A.8.28 client-side RLS reliance — documented architectural choice
  - Direction pre-check at API layer (RPC catches with cleaner code)
  - V16 + Art.32 + Art.5(1)(b) low-severity logging nits
