Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * fix: address PR review — map BAS 4500–4899, strip CRLF in SRU, document P3 - Map BAS accounts 4500–4599 (legoarbeten), 4700–4899 (diverse varuinköpskostnader) to SRU 7512 so they are not silently dropped from INK2R declarations - Strip \r\n in sanitizeString to prevent CRLF injection in SRU fields - Document P3 period suffix limitation for brutet räkenskapsår Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * fix: correct BAS 4500-4599, 4700-4899 mapping from 7512 to 7511 Per the official BAS-to-SRU mapping, these account ranges are cost of goods (legoarbeten, inkurans, svinn) and belong under 7511 (Råvaror och förnödenheter), not 7512 (Handelsvaror). 7512 remains 4600-4699. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * fix: Swedish VAT compliance — representation VAT, domestic RC, full BAS 26xx mapping, SIE encoding - Representation expenses now default to reduced_12 VAT (ML 13 kap 24-25 §§); income tax deduction was abolished 2017 but VAT deduction at 12% remains - Domestic reverse charge (byggtjänster etc.) uses 2647 instead of 2645, with distinct line descriptions for Swedish vs EU/non-EU RC - VAT declaration maps all BAS 26xx variant accounts (egna uttag 2612/2622/2632, uthyrning 2613/2623/2633, VMB 2616/2626/2636, import 2615/2625/2635, domestic RC 2647, frivillig skattskyldighet 2642) and revenue variants (3108/3105/3004/3100) to correct momsdeklaration rutor - SIE parser: remove unreliable #FORMAT PC8 encoding detection (most software exports UTF-8 with PC8 header), parse #FLAGGA for import-already-done warning, default SIE type to 1 when absent, fix RTRANS/BTRANS documentation - SIE export: add #RAR -1 (previous fiscal year), fix UB = IB + movements - Error messages: add pattern matching for locked period trigger errors Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * fix: address Greptile review — update ruta49 JSDoc, use null sentinel in error map Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * fix: harden storno CAS guard, document integrity, and BFNAR archive compliance - Storno: defer original→reversed until both entries succeed, add CAS guard for concurrent reversals, use cancelEntry() instead of delete - Document: add document.accessed event, enrich archive manifest with metadata, add BFNAR 2013:2 systemdokumentation to full archive export - Verify cron: run daily, configurable batch size, include company_id in audit - Migrations: integrity audit actions, document version chain, metadata immutability, audit deletions, fix immutability for posted/cancelled Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * fix: address Greptile review — allow is_current_version in immutability trigger, log cancelEntry errors - Remove is_current_version from blocked fields in enforce_document_metadata_immutability trigger so create_document_version RPC can supersede documents linked to posted entries - Add error logging to cancelEntry for observability on cleanup failures Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> --------- Co-authored-by: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
