Edge: the register, as data
Everything the site runs on is a verified register: specifications with their sources, prices with their dates and kinds, scores with the arithmetic shown, dealer networks, tyre fitment. Edge is that register turned into working intelligence for the businesses that need it in bulk.
The public pages already show live aggregates computed from the same data: how scores are distributed across the register, how dense each maker's network is, how many tyre sizes are mapped across how many fitments. What Edge adds is the full breakdowns, the series behind them and the exports.
It is the same record, not a second one. A figure an institution reads in Edge is the figure a buyer reads on the page, and it carries the same date and the same grade.
