Definition
The cookbook scores 450 candidate beer pairs from two catalogues with a three-level Score per pair: 40 assert sameAs, 50 go to a curator, and 360 stay unlinked. Companion Nouls about name, brewery, and style localize disagreements, while ABV stays in arithmetic.
There is no fitted threshold: route() rounds the score to the nearest level, so the middle level's wording drives behavior, and the middle is explicitly a curator path rather than an automatic merge.
