Each concept is read twice: whether the approach carries it, and whether the approach's own sources claim it. A concept that is absent and was never claimed is a gap in the field rather than a failure of the work, and is marked out of scope.
Segmental autonomy
PresentClaimed · deliveredDefinition · Arend Lijphart, Democracy in Plural Societies (1977)
In a deeply divided society, each group governs its own internal affairs — its schools, its family law — within its own sphere, instead of everyone living under one uniform rule.
Analysis
Each region's cultural norms and legal policies genuinely govern the answers given in it, across 50 countries and 493 regions, and the norms were human-verified rather than inferred. This is the only built system in the map where a user's sphere determines the rule applied to them.
Choice-of-law rule
PartialClaimed · partialDefinition · Friedrich Carl von Savigny, System of the Modern Roman Law (1849)
When several bodies of rules could govern the same case, an explicit rule decides which one actually does — and states the reason. Without such a rule, "different rules for different groups" has no answer for the cases in between.
Analysis
The system does state which norm it applied and cite it, which is half of Savigny's requirement and more than AP-09 manages. The half that is missing is the case in between: a query implicating two countries' norms has no allocation rule, because the geography is read off the query rather than reasoned about.
Mutual veto and proportionality
AbsentNot claimed · out of scopeDefinition · Arend Lijphart, Democracy in Plural Societies (1977)
Decisions that affect all groups require every group's consent, and representation is proportional to each group's size — so no segment can simply be outvoted on what matters most to it.
Analysis
Norms are collected from regions and compiled into training data; no region consents to the compilation, none can veto how it is represented, and representation follows the availability of documented norms rather than population.
