The model all five render
Every prototype reads one file. The sections below are the questions, the weight column is what moves the price, and both are published here because a page that asks somebody twenty questions owes them the list before they start, and a weighting a reader cannot see is a price a reader cannot check.

The configurator does not compute a price. Weighted selections add up, the total lands in a band, and the band names one of the four tiers that already exist and its price. Nothing here invents a number — a price is the first thing the pack↗ says may not be invented, and a checkout that emitted "£347" would be inventing one with extra steps. A build check fails the release if a band names an offer that is not on the offer list↗. {{claim:lab-price-is-a-band}}
The prebaked starts are hypotheses. Nobody has counted how common any of those five shapes is. Each brief records which one it started from, so the team reading it can tell what was assumed from what was answered — which is the only thing that makes starting from a guess safe rather than fast. {{claim:lab-scenarios-are-hypotheses}}
