Calculation validation

The live calculation library is run against the inputs of Orchard 14 (CLEMENPONS) and compared with the values the existing calculator produces for the same Orchard. This is the mathematical sign-off evidence: if these match, the engine reproduces the approved model.

All 8 values match the existing calculator within 1e-9 tolerance.

Notes for testing

  • The same chain is asserted in the automated suite (benchmark.integration.test.ts), so a regression fails the build rather than only this page.
  • This page covers Drip. Micro has no populated non-error example in the supplied workbook, and Centre Pivot has no legacy data at all — both need a client-supplied benchmark before they can be signed off the same way.
