* 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).

* docs(decisions): record the 2026-09-06 ten-issue batch's first-principles choices

Carries the DECISIONS.md lines for PRs #2337 #2339 #2340 #2341 #2342 #2343 #2344 #2345 #2346 #2347 in one place so the ten branches do not conflict on this file.

* 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).

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

* 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
