For V/E/S items the layers with a declared expectation are averaged with the weights V 2, E 1, S 1, normalized over the declared layers (v+e+s gives V 0.5 / E 0.25 / S 0.25; a value-only item is unchanged at 1.0). Each layer scores 1.0 for an exact hierarchy match, 0.5 for an adjacent code, 0 otherwise. When an expectation names both the prevailing and the deprioritized code, the prevailing side carries 0.7 of the layer score.","layerWeighting":"Value carries double weight because it is the layer that actually varies with the scenario. A pack maps evidence and source codes that are close to constant within a provision, so those two layers can largely be answered from the published pack without reading the scenario; leaving all three equal let two thirds of an item be decided by provision-constant lookup (calibration 2026-08-15).","adjacency":"Adjacency comes from the vocabulary itself. Value codes (19) sit on the Schwartz refined-theory circumplex, so adjacency is a distance of 1 on that circle. Evidence codes (10) are ordered by rigor and source codes (10) by authority, so adjacency there is a distance of 1 in the catalogue.","aggregation":"Total = sum(weight x conformance) / sum(weight) over every item in the published set.
