E-Invoice VAT Calculation Verifier

Recompute an e-invoice's line VAT, per-category tax subtotals, tax total, and grand total from its line items under a supplied rounding convention, then compare against the document-asserted amounts. Reverse-charge and zero-rate categories are treated as zero VAT. Verifies arithmetic consistency only, not statutory rate correctness. Middle node of the einvoice-validation-pipeline chain. Zero network, zero PII.
