# User Guide

The conceptual core of `numeraire`: the mental model behind the point-in-time views, the capability
layer, the walk-forward engine family, the evaluators and the result schema, the portfolio
simulator, the open registries, and the one dependency rule that keeps the whole thing honest — and
then the method-comparison workflow that scores competing pricing models on one shared panel of test
assets.
