Since the #1385 squash-merge every production build failed with 'Two or
more assets with different content were emitted to the same output path'
on [root-of-the-server]__1ge0sz5._.js: two distinct server chunk groups
(an AWS smithy helper chunk and the withRouteContext auth chunk) hash to
the same chunk name. The graph change that tipped the chunk layout into
the colliding state was entity-mapper.ts (arcim-migration extension
entry graph) importing lib/vat/supplier-invoice-line-checks, which
drags lib/money into the extension root.
Move normalizeVatRateToFraction into an import-free leaf module
(lib/vat/vat-rate-unit.ts), re-export it from
supplier-invoice-line-checks for all existing callers, and point
entity-mapper at the leaf. Behavior is unchanged (511 targeted tests
pass); the server chunk graph returns to the pre-#1385 shape that
builds cleanly. Verified: npm run build fails on ff864ad3d and passes
with this change.

Closes the remaining #310 write paths: credit-note item copies (web, v1,
pending-operations) and arcim-migration supplier imports now normalize
vat_rate to the decimal-fraction unit before storage, and a NOT VALID
CHECK constraint guards every new supplier_invoice_items row. Customer
invoice items deliberately stay percent; legacy supplier rows are left
untouched so posted-entry reversals reuse the exact original values.
Fixes#310

* fix(supplier-invoices): flag foreign 0 % lines with reverse charge switched off
A foreign supplier charging no Swedish VAT is normally omvand
skattskyldighet. With the reverse-charge switch off,
createSupplierInvoiceRegistrationEntry emits neither the 26x4 output leg nor
the 44xx/45xx basis lines, so ruta 20-24, 30-32 and 48 all stay empty and the
momsdeklaration takes a shape Skatteverket rejects. For a fully deductible
purchase the net moms att betala is unchanged, which is exactly why this goes
unnoticed. The form already auto-ticks reverse charge for eu_business but not
for non_eu_business, so that path slips through silently.
Adds a pure helper plus a non-blocking banner cloned from the existing
rc_account_warning block. Deliberately silent for swedish_business, where 0 %
is a genuine exemption that belongs in no ruta at all, and phrased as a
question rather than an assertion: a non-EU goods purchase cleared at customs
is legitimately 0 % without reverse charge, and pushing that user into
ticking the switch would manufacture a new wrong verifikat.
Does not add the exempt/import/other picker the issue proposes:
supplier_invoices.vat_treatment is metadata that no booking or ruta mapping
reads, and the codebase cannot book import VAT at all, so an import option
would imply ruta 50/60 were handled when they are not.

* fix(supplier-invoices): name the local-VAT case in the foreign 0 % hint
Review flagged that the most common foreign document a Swedish small company
sees is an invoice carrying the supplier's OWN local VAT, booked at 0 %
Swedish VAT with reverse charge correctly off. The banner fires there, and
the previous copy only offered "momsfri av annat skal, till exempel en
varuimport" as the way out, which does not describe that invoice at all: it
is not VAT-free, it carries foreign VAT.
Names both legitimate cases explicitly and says 0 % is correct in them, so
the hint cannot read as an instruction to tick reverse charge on a purchase
where that would produce a wrong verifikat. Title also narrowed to "utan
svensk moms" for the same reason.

Supplier invoice items store vat_rate as a decimal fraction (0.25) while
customer invoices use integer percent (25). The shared Zod schema accepted
0-100, so a percent-shaped vat_rate silently booked 2500 % VAT via
line_total * vat_rate, and the MCP inbox-conversion path staged the AI
extraction's percent-integer vatRate straight into the decimal column with
per-line vat_amount 0. Part of #310.
- CreateSupplierInvoiceItemSchema.vat_rate is now a literal union of the
statutory decimal set (0, 0.06, 0.12, 0.25) with a unit-hint error,
covering the cookie route, the invoice-inbox convert route, and /api/v1
(whose runtime ALLOWED_SV_VAT_RATES guard stays as defense in depth).
- New shared normalizeVatRateToDecimal() in lib/vat: percent-shaped values
(25, 12, 6) divide by 100, results snap to the legal Swedish set, and
anything else (foreign 19/20, non-finite) maps to 0.
- gnubok_create_supplier_invoice_from_inbox normalizes vatRate at the
extraction boundary and derives per-line vat_amount when the extraction
carries none, so the staged header vat_amount is honest.
- The pending-operation executor normalizes staged vat_rate on insert, so
rows staged before this fix cannot book percent-scaled VAT.

* fix(supplier-invoices): warn on class 1/6 accounts for reverse charge lines (#863)
Item 2 of #863: when omvand skattskyldighet is on, lines booked on an
account starting with 1 (assets) or 6 draw a non-blocking warning banner
in the Kontering card naming the rows; reverse charge purchases normally
sit on 4xxx/5xxx cost accounts. Advisory only, since class 6 has
legitimate reverse charge uses (e.g. 6540 IT-tjanster for EU cloud
services), so submission is never blocked.
Item 1 (block VAT rates outside the legal set 25/12/6/0) already shipped
in PR #902; this change extracts that check plus the new one into a pure
tested helper, lib/vat/supplier-invoice-line-checks.ts, which is now also
the single source for the legal rate list used by the VAT rate preset
dropdown.
Item 3 (confirming the reason for a 0 % rate) is deferred: it is a UX
design question, not a validation gap.

* docs(vat): note food-rate transition dates above LEGAL_VAT_RATES
Compliance-bot finding on PR #1034: the allow-list comment now records
that livsmedel moved 12 % to 6 % on 1 April 2026 (Prop. 2025/26:55,
ML 2023:200) and that the reduction is legislated to revert after
31 December 2027, when 6 % stays legal for books/transport but stops
being the food rate. The static list cannot express per-category
temporal validity; revisit at the reversion. Comment-only change.
