Calculation Engines¶
This category covers reusable calculation patterns: audit trails that make
calculation logic traceable, sensitivity/what-if toggles, and scenario comparison
structures built without duplicating formula logic per scenario. Every component
here must remain implementation-agnostic in its specification — the business rule
comes first, the Excel mechanics are secondary, matching the discipline required of
individual products' calculation-specification.md.
This directory currently holds no individual component specifications. See the
Calculation Engines section of ../component-catalog.md
for the current proposed components in this category (e.g. Core Calculation Audit
Trail, Sensitivity Analysis Toggle, Scenario Comparison Table). Once a component in
this category is developed past a single catalog row, its full specification (using
the ../_template/ scaffold) would live in a subdirectory here.
This README establishes no policy of its own.
