 [2026-09-01] Skeptic BLOCK on woo failed-order removal fixed by: freeze guards repeated on the DELETE statement (TOCTOU), is_paid=false + legacy_transaction_id null guards, orderRemoves gated on !orderIsPaid. No BEFORE DELETE trigger/RPC: the is_paid guard makes the cascade race unreachable (refund children only exist under paid parents).
 [2026-09-01] EB claim guard, skeptic round (PR #2116): active-company standing state (enabled cash_accounts + enabled accounts on its live-ish rows) outranks sibling claims COMPANY-wide, not row-wide: a bank-list renewal arrives on a fresh row and must not switch a working feed off. pending_selection rows neither claim nor remember deselections (unconfirmed callback output; also stops fail-closed writes from poisoning later connects). Guard-disabled accounts are never mirrored from the callback (mirroring enabled:false can promote the seeded primary 1930 manual row and disable it under a foreign identity) and the selection save skips allocation+mirror for disabled never-mirrored accounts, so the no-slot-burned invariant holds end to end. Deselection carry got a picker note; enabling an account clears the guard flags. Legacy both-companies-enabled overlaps stay untouched (Swedish review advisory: prod sweep is a follow-up, not this PR).
 [2026-09-01] EB claim guard round 2 (skeptic re-verify): pending_selection rows are asymmetric, not excluded: their ENABLED accounts still claim (attach-created rows hold offered accounts with no cash rows until saved; excluding them reopened the attach-window double-booking), while their disabled flags stay out of deselection memory (unconfirmed callback output). Both fetchAllRows claim queries order('id'): unordered .range() pagination can silently skip rows at page boundaries, and a skipped row is a missed claim (fail-open).
+[2026-09-01] Invoice-register coverage detection keys on pre-boundary AR lines (1510/1513), not source_type='import': the reporter's 2026 invoice history was backfilled as source_type='manual' verifikat, which an import-keyed marker (fetchMigrationCoverageEnd) would miss; widening to class-3 revenue would false-flag cash/webshop sales.
 [2026-09-01] F2 bank-data staleness: ship freshness reads only (last_synced_at/consent_expires/error_message on gnubok_connect_bank + new GET /api/v1/.../bank-connections, scope companies:read mirroring the MCP mapping): the daily cron already syncs server-side, so visibility is what the incident lacked; an agent-triggerable sync is a product bet (EB call cost, runaway agents) and was deferred by Emil.
 [2026-09-01] Verifikationsserie in the Ny verifikation modal is a closed dropdown instead of a one-letter free-text field: a typo there silently opens a brand-new series with its own number sequence, and the letters only mean anything if everyone uses the same ones. The letters are NOT prescribed by law (BFL 5 kap. 7 § requires only unbroken systematic numbering within each series), and the incumbents disagree: Björn Lundén uses A Huvudserie, F Kundfakturor, I Inbetalningar, L Leverantörsfakturor, N Löner, U Utbetalningar, J Bokslut. We ship FORTNOX's table verbatim (A Redovisning, B Kundfakturor, C Inbetalningar från kunder, D Leverantörsfakturor, E Utbetalningar till leverantörer, F Kassa, G Avskrivning, H Periodisering, I Bokslut, J Revisor, K Lön, L Kontantfaktura, M Momsrapport), from their own Systemdokumentation, because Fortnox is the system most companies migrate here from and an imported ledger should keep its meaning. REJECTED an earlier draft that labelled A as Kundfakturor: A is the general series manual entries land in (the one point Fortnox and BL agree on, and Fortnox allows manuell kontering ONLY in A), and migration 20260526120700 ships every source_type defaulting to 'A', so every existing company's A series already holds everything. Calling it Kundfakturor would mislabel their entire history and the modal's own default. The list is closed but any letter the company already configured, or that a draft was saved with, is appended so no existing value can fall out of the picker. Also: tabbing or clicking into an untouched amount field now proposes the outstanding difference (pre-selected, so typing replaces it) when the row already has an account and the difference belongs on that side. This deliberately reverses part of the note in updateLine that said a balancing amount must never auto-fill: that note was about filling on ACCOUNT selection, which stole the amount before the user had a chance to split it. Filling on focus keeps the split case intact because the proposal is selected text, and it fixes the common moms case where the last line is just the remainder.
 [2026-09-01] Settings PUT cross-field VAT validations scoped to touched field groups (vat-completeness, 40m-monthly, periodisk sammanstallning), not fixed at onboarding: partial saves from surfaces without VAT fields (invoice bank-details dialog) were hard-blocked by pre-existing vat_registered-without-number state (Marketio Lab case). The invariant still holds on every save that touches its group; explicit null now counts as a clear instead of falling back to the stored value during validation. Onboarding-side VAT number collection left as follow-up.

 - Ordering is by created_at (registration time), not invoice_date. Backdated invoices therefore appear where they were created, not where their date falls: filter on ?date_from / ?date_to when you care about the business date.
 - Cursor pagination: pass ?cursor=<next_cursor> from the previous response. A stale or tampered cursor is ignored and the first page is returned again.
 - Quotes (document_type=quote, offert) carry valid_until and quote_status (open | accepted | declined | expired). "expired" is derived: an open quote past valid_until; filter with ?quote_status=expired. Quotes never book and are never payable: convert an accepted quote to an invoice in the dashboard first.
+- The register only contains invoices created in Accounted. A company migrated or backfilled mid-year has real customer invoices that exist only as journal entries and are NOT in this list. Check meta.coverage: when has_pre_register_invoices is true, treat periods before covers_from as not answered by this endpoint (query journal entries instead).
