Raised by the Swedish compliance bot on #1395. The template called itself "Representation (avdragsgill, 25% moms)" and labelled its cost line "Representation avdragsgill", but booked to 6072, which BAS 2026 defines as Representation, EJ avdragsgill. The swedish-vat skill lists that exact confusion under Representation errors: "Not separating avdragsgill/ej avdragsgill on correct accounts (6071 vs 6072)". The account was right and the words were wrong. Meal representation stopped being income-tax deductible in 2017, so 6072 is where the cost belongs; only enklare fortaring (max 60 kr per person) is still deductible, on 6071. Renamed to "Representation, maltid (ej avdragsgill)" and relabelled to match. VAT moves from 25% to the 12% restaurang-och-catering rate our own static representation_external template in booking-templates.ts already used, so the two template systems stop contradicting each other, with the paired net ratio 1/1.12. A legal_note now carries the 300 kr per person VAT cap, which this format cannot compute because a template sees only a total and never a participant count, plus the reminder that the rate follows the underlag rather than the template. Correcting the record on one point: the seeded ratio 0.8 was NOT a phantom 80% deductibility rule, as the bot suggested and as I first repeated. 1/1.25 = 0.8, so it was the net-of-VAT fraction pairing with the 25% rate, and the arithmetic balanced. Only the naming and the missing cap were wrong. The ratio is now commented in the file so the next reader does not make the same misreading. Slug deliberately unchanged though it still reads "avdragsgill": a slug is an identifier, not a label (packs/README.md). Renaming it would retire this template and insert a new one, breaking every company's booking_template_usage history. The drift guard caught the rename, which exposed that the test joined packs to seeded rows by NAME. That is the same fragility that made pack_slug the sync's key, so INTENTIONAL_DIVERGENCES now records each entry's seededName explicitly.

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 100+ MCP (Model Context Protocol) tools with scoped API keys, 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.
