 [2026-09-08] #2391 skeptic pass: orgNumberKey only strips hyphens and spaces and only unprefixes 12-digit values behind 16/18/19/20. Reason: 26 prod supplier rows hold a VAT number (orgnr + 01, prefixes 55/52/87) in org_number, and 'last 10 of any 12 digits' would have rewritten them to another company's identity; letters stay because BE0123456789 is not the Swedish 0123456789. The matcher scans live suppliers only (archived_at IS NULL), the list and v1 search compare without separators, the CSV import and the provider migration orchestrator key and write through the same rule.
 [2026-09-08] correctEntry re-points the original entry's transaction_voucher_links rows to the corrected entry (lib/core/bookkeeping/storno-service.ts relinkTransactionsToEntry) instead of deleting them as issue #2364 proposed. Why: for a samlingsverifikat (bulk-book N>1) the junction is the row's only anchor, so deleting it would push rows the corrected verifikat still explains back into Att bokföra; the pointer column already follows the correction and the junction now follows it the same way, so every reader (is_transaction_booked, fetchJunctionLinkedTxIds, the bulk_book RPC) sees one live anchor. Rejected: a relink_entry_anchors RPC moving pointer and junction atomically (a migration plus pg test for a path that is already best-effort across five other statements; revisit if a partial failure ever shows up in the surfaced transactionRelinkError). Prod repair (planned, runs after merge on the founder's go; completion gets its own dated entry): the 7 stale links (3 companies) all sit on rows whose pointer names a posted entry (4 on a correction chain, 3 from a June 2026 samlingsverifikat storno that predates the junction cleanup and were re-booked 1:1); they will be re-pointed to the pointer's entry, the same rule the fix applies, rather than deleted.
 [2026-09-08] delete_last_voucher returns a correction's bank anchors (transactions.journal_entry_id and transaction_voucher_links rows) to correction_of_id before the row is deleted (migration 20260908095907). Why: the #2364 skeptic showed that once the junction follows the correction, the two-step undo (delete the correction, then the storno) cascaded the links away and restored an original that explains bank rows nobody points at, so the rows surfaced as bookable again; before, the links had stayed on the original by accident. Chosen over releasing the rows (the restored original would still explain them, same trap) and over a TS pre-step in the DELETE route (not atomic with the RPC's own guards: a refused delete would leave anchors on a reversed entry). A duplicate of a link the original already holds is dropped, not re-pointed (UNIQUE (transaction_id, journal_entry_id)).
+[2026-09-08] Medelantal anställda (Not 2, ÅRL 5:20 §) gets a whole-number override on arsredovisning_narratives (migration 20260908130127) instead of the free-text note override the support request asked for. Why: the number keeps the statutory sentence and the iXBRL MedelantaletAnstallda fact correct; free text would let a non-compliant note through and could not be tagged. One resolver (lib/salary/medelantal.ts resolveMedelantalAnstallda: override, else FTE average over employees) feeds the K2 and K3 note builders and the iXBRL input, which also reads the previous period's override so the jämförelseår column shows the same figure the previous year's document did. Rejected: rounding 0.5 up globally (silently changes every company's note and does nothing for the 148 of 195 aktiebolag with salary but no employees rows); asking the user to backdate employment_start (fixes one company, misstates the hire date).
 [2026-09-08] Issue #2413 BAS 2026 kontogrupp 12: kept 1249/1259/1269 in the catalog renamed after their free heads and dropped only 1241/1242/1251/1261, instead of removing all seven retired sub-accounts and moving the asset module's vehicle/computer defaults to BAS 2026 (1226/1224 on 1229): the asset module's DEFAULT_ACCOUNTS_BY_CATEGORY still books vehicles on 1240/1249 and computers on 1250/1259 (31 live assets in prod, guard test requires the triple in BAS_REFERENCE), so dropping the contra accounts would have forced a depreciation-default change into a label fix; that change is the founder's call and lives in #2414. The prod backfill renames only the exact catalog literal next to a free-labelled head, so old-BAS imports (1240 Bilar + 1249 Ack. avskr. bilar) and user renames stay untouched.
