3.6.459September 6, 2026

Governed VAT Treatment Decisions

16 changes
Feature5 items
  • The calculation API can now return separate sales VAT, import VAT, customs duty and fee outcomes with explicit completeness and provenance.
  • Scheduled source processing prepares the latest treatment candidate for administrators to inspect, while historical preparation remains operator-triggered.
  • Administrators can inspect exact partial coverage, review shadow results, and keep approval separate from production activation.
  • Safe retries return the original stored decision, while unresolved treatment context remains visible instead of being guessed.
  • Missing legal applicability dates remain reviewable source evidence and cannot become active treatment coverage.
Security4 items
  • Treatment approval, cutover and rollback use sealed impact previews and fresh administrator MFA; automated source processing remains candidate-only.
  • Corrections cover every release still active in a staged rollout, and present-day profile defaults are never treated as historical legal evidence.
  • Correction revalidation is lease-fenced, waits for the reviewed replacement rollout, and creates at most one successor for an affected decision.
  • Both API versions now apply the same IP protection before API-key verification, in addition to authenticated per-key limits.
Fix7 items
  • Treatment evidence stays visible below the administrator header when opened, and roadmap previews now match the roadmap page.
  • Repeated treatment review selections refocus the correct card, and governance controls refresh after lifecycle changes.
  • Administrators can prepare a treatment candidate from retained source evidence without receiving permission to modify that evidence.
  • Equivalent source interpretations are combined without discarding their evidence, while genuine conflicts remain visible for review.
  • Catalog operations now distinguish configured synchronization from available processing, and enabled installations wait for fresh processing status.
  • Large treatment shadow reviews cover and seal the complete decision history, while staged rollout corrections continue independently for each ready scope.
  • Current rollout totals no longer include historical activations, so administrators see only the authority currently serving each rollout scope.
