Evidence, not a trust badge

Calculator verification status

We maintain ten evidence scenarios for each jurisdiction. This page separates the source used to derive each expected result from whether that full fixture pack runs against its engine in CI.

Official calculator matches

Full outputs matched an official calculator or estimator.

Published example matches

Results matched worked examples published in an official rule or workbook.

156

Needs official cross-check

Formula interpretations or partial tables still need independent confirmation.

293

Document-derived

Expected results were derived from official rules, tables, charts, or worksheets.

Evidence scenarios executed as full engine regression fixtures

51 jurisdiction packs currently run all ten scenarios against their calculation engine on every code change with a one-dollar tolerance or an asserted fail-closed outcome.

How to read this status

Source-derived does not mean independently matched by a state calculator. It means the expected result was worked from the cited official formula and then used as a regression record. The needs-cross-check count identifies the subset with unresolved interpretation, partial-table, approximation, or independent-confirmation work still open. Some jurisdictions do not publish an interactive calculator. Others block automated access or require inputs outside the scope of a simplified estimator.

These tests reduce software errors, but they do not certify a result for court. The court or state agency calculation controls.
