SAFE OUTCOME

  • TRUSTED SPLIT VAT FACTS

    • 7% line • 19% line • Total VAT • Audit trail

  • NEEDS REVIEW

    • Evidence incomplete • Conflict preserved • No silent guess

Safe by design: explicit evidence beats naive fallback.

What this enables

  • DETERMINISTIC

    Arithmetic and rules are checked.

  • EXPLAINABLE

    Every outcome can be traced back.

  • REVIEWABLE

    Ambiguity becomes a task, not a hidden error.

  • TRUSTED

    Good evidence produces good facts.
