Deterministic lookup over a version-pinned mandate table: given supplier/buyer country, transaction type, and transaction date, routes to the applicable e-invoicing regime, format, phase status, and transmission channel. France's B2B receive obligation is live from 2026-09-01 via the PDP channel; Germany's XRechnung B2G/B2B receive obligation is already live; Belgium's Peppol BIS 3.0 mandate has been live since 2026-01-01; Poland's KSeF FA(3) mandatory-use phase-in starts 2026-02-01; UAE PINT-AE and Malaysia MyInvois dates are DRAFT-PIN pending re-confirmation. Zero network.

Scope
Third node of the einvoice-validation-pipeline chain (art-293→294→295→296). A deterministic lookup, not a live regulatory feed; refresh the mandate table at each rebuild. See einvoice-validation-pipeline chain.
