* fix(sie-import): reject overlap-but-not-contain fiscal periods ensureFiscalPeriod previously fell back silently to any partially-overlapping fiscal_period when no period fully contained the SIE file's #RAR range. That stamped every imported voucher with a fiscal_period_id whose date window didn't cover the voucher's own entry_date — breaking the SIE invariant that #VER dates fall inside #RAR and BFL 5 kap. (verifikationsnummer i obruten serie per räkenskapsår). Reproduced in production: a customer with a broken fiscal year (Mar–Feb) had their previous-year SIE collapse into a calendar 2026 period, mixing 116 prior-year vouchers into the current period's voucher sequence. Now: fully-contained → reuse; partial overlap → reject with a clear Swedish message pointing at the period dates that would need to be fixed; no overlap → create a new period as before. Adds a defense-in-depth pre-check in executeImport that rejects with a Swedish error if any individual #VER date falls outside the resolved fiscal period — catches multi-year SIE files (which gnubok does not yet support) without producing corrupted journal entries.

A transient network error or RLS failure returned null for data, the guard body skipped, and importVouchers ran with no date validation — the same data-corruption path the guard exists to close. Now: surface the fetch error to the user (Swedish) and abort the import. Also switches the date comparison from millisecond timestamps to YYYY-MM-DD string compare. SIE per spec is date-only and our parser normalizes to midnight, but string compare matches the underlying DATE columns exactly and removes a latent off-by-one risk on the period's last day if a future parser change ever attached a time component to v.date.

gnubok
Open-source Swedish accounting software for sole traders (enskild firma) and limited companies (aktiebolag).
What is gnubok?
gnubok implements double-entry bookkeeping compliant with Swedish accounting law (Bokforingslagen). It supports the BAS 2026 chart of accounts, handles VAT declarations (momsdeklaration), SIE import/export, and enforces 7-year document retention. Built for sole traders and limited companies operating in Sweden.
Features
- Double-entry bookkeeping -- BAS 2026 chart of accounts, draft/commit workflow, sequential voucher numbering
- Invoicing -- Create, send, and track invoices with mixed VAT rates and PDF generation
- Bank reconciliation -- PSD2 bank connection via Enable Banking, 4-pass automatic matching
- VAT declaration -- SKV 4700 form mapping, per-rate breakdown, EU/export handling
- Tax reports -- NE-bilaga, INK2, SRU export for Skatteverket
- Supplier invoices -- Registration, payment tracking, input VAT deduction
- Document archive -- SHA-256 integrity, 7-year retention enforcement, full archive ZIP export
- SIE import/export -- Standard Swedish accounting interchange format
- Extension system -- Opt-in plugins for AI categorization, receipt OCR, email, calendar, and more
