Demo
The same items, ranked two ways: once by your criteria, once by purchased attention (exposure, how much advertising and visibility has been bought around each item). Switch domains, move the sliders, and watch which item comes out on top change.

What this is and is not
Item ratings, prices, and exposure numbers throughout this demo are illustrative archetypes, not measurements of real products or real advertising spend. What a fair criteria layer actually gives sellers is the ability to make price and product decisions against real, stated buyer preferences instead of chasing purchased exposure. This layer claims symmetric information as the fairness mechanism here, not a guarantee that these markets become fair on their own.
