* feat(mcp): article-aware invoice updates with gnubok_get_invoice round trip and rebooking preview gnubok_update_invoice items are a FULL REPLACE, had no article fields, and no MCP tool returned invoice lines, so a quantity fix rebuilt from memory wrote article_id/revenue_account null and reverted vat_rate to the customer default: revenue silently moved from the article account (3041) to the VAT-derived default, invisible in the approval preview. - gnubok_get_invoice (invoices:read, search-only): header plus every line with article_id, revenue_account, vat_rate, dimensions, editable_draft - gnubok_update_invoice lines accept article_id with the same prefill and default-set VAT adoption guard as create; permitted-set VAT gate at staging; preview carries the new lines' effective booking and a snapshot of the lines being replaced - commitUpdateInvoice scope-checks staged article ids like create does - OperationPreview: update_invoice preview (current vs new lines, header diffs, totals); create_invoice lines show VAT rate and posting account - invoicing skill points at the read-before-replace round trip Closes #1642 Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01FkUfWtuFCUkNtRAgMQCse2 * fix(mcp): use roundOre for update-invoice preview totals so the ore ratchet stays at baseline The preview-building code in gnubok_update_invoice introduced five naive Math.round(x * 100) / 100 occurrences, tripping check:guards (naive-ore-round 627 vs baseline 622) and failing Core Build on PR #1993. roundOre from @/lib/money is the sanctioned helper and was already imported in this file. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01FkUfWtuFCUkNtRAgMQCse2 * fix(mcp): make the invoice round trip lossless for text, ROT/RUT and accrual lines Skeptic review of #1993 found three round-trip breaks for web-created drafts edited via MCP (the exact silent-loss class issue #1642 reports): - Text rows: the update pre-gate and resolveInvoiceLineFromArticle rejected quantity <= 0 before looking at line_type, so any draft with a free-text spacer row could not be edited at all, and the natural agent recovery (drop the row and retry the FULL REPLACE) silently deleted invoice content. Text rows are now exempt from the quantity/description/unit/price gates (CreateInvoiceItemSchema parity), normalized to the zeroed stored shape, excluded from the staged totals and the VAT gate (commitCreateInvoice billableItems parity), and line_type is declared on both the create and update item schemas. - ROT/RUT: gnubok_get_invoice omitted housing_designation, apartment_number and brf_org_number, so an items replace on a ROT draft either failed AFTER approval ('Fastighetsbeteckning krävs för ROT-avdrag') or, for a schema-conformant agent, silently stripped the avdrag and the stored personnummer. The three property columns (property identifiers, never the personnummer ciphertext) are now returned per line, the deduction fields are declared on the update item schema, deduction_type rides on the current_items snapshot and the new-lines preview, and a staging-time completeness gate (arbetstyp/timmar via validateDeductionLines, fastighetsbeteckning for ROT, personnummer availability on the invoice or the individual's kundkort) surfaces the failure to the agent instead of the approver. - Declared-schema gap: revenue_account and the accrual fields were accepted on pass-through but undeclared, so a schema-conformant agent dropped a manual posting-account override or a periodisering on pass-back. They are now declared on the update item schema (revenue_account also on create; create deliberately does NOT declare deduction/accrual fields because commitCreateInvoice drops them), and the approval preview shows ROT/RUT-avdrag and the periodisering period per line. tools/list ceiling check after the two new create-schema properties: 63337 of 63400.

Accounted
Open-source Swedish accounting software for sole traders (enskild firma) and limited companies (aktiebolag). Double-entry bookkeeping that complies with Swedish accounting law, built to be operated by you or by your AI agent.
Website · Hosted app · Documentation
Why Accounted?
Compliant by construction. Accounted implements double-entry bookkeeping under Swedish accounting law (Bokföringslagen). Voucher immutability, sequential voucher numbering, period locks, and 7-year document retention are enforced by database triggers, not by convention. Corrections are made the legal way, with reversal entries (storno), never by editing history. See ARCHITECTURE.md for how.
Agent-native. The full bookkeeping engine is exposed as 150+ MCP (Model Context Protocol) tools with scoped API keys or OAuth, so an AI agent can do the books in Accounted: categorize transactions, draft vouchers, reconcile periods, and prepare declarations. Posting is staged for human approval, so the agent proposes and you decide.
Yours to run. AGPL-3.0 licensed and fully self-hostable with Docker and Supabase. Use the hosted version at app.gnubok.se or run your own.
