How this ranking works
Every candidate is inserted into the same complete reference build and evaluated by the production compatibility rule set. Any ERROR removes the product before price or quality can influence the result.
Among buildable products, headroom and quality use typed category specifications. Stable product IDs break ties. Affiliate status and commission are absent from the scoring input.
