Each concept is read twice: whether the approach carries it over, and whether the approach's own sources claim it. A concept that the approach claims but does not carry over is a shortfall. A concept that it neither claims nor carries over is an omission, which marks a gap in the field rather than a failure of the work.
Segmental autonomy
PresentClaimed · preservedDefinition (Arend Lijphart, Democracy in Plural Societies, 1977)
In a deeply divided society, each group governs its own internal affairs (e.g., its schools and its family law) within its own sphere, instead of everyone living under one uniform rule.
Analysis
The segments here are national jurisdictions, and each keeps authority over its own internal affairs. Certification applies to the state's oversight system rather than to any firm or model within it. This is Lijphart's structure taken at face value. The segments govern themselves, and the international layer only certifies that they do.
Choice-of-law rule
AbsentOmissionDefinition (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" gives no answer for the cases that fall between groups.
Analysis
Certification says which states meet a standard, but it never says whose rules govern a given case. This arrangement gives no answer for a model deployed across borders, or for a user in one jurisdiction querying a system hosted in another. The in-between cases that Savigny's rule exists for are entirely outside its scope.
Mutual veto and proportionality
PartialShortfall · partially preservedDefinition (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. As a result, no segment can simply be outvoted on what matters most to it.
Analysis
Import and export restrictions give each certified state real leverage over the conduct of the others. This is closer to a mutual check than anything else in this regime. However, the leverage is proportional to market power, not a veto proportional to stake. A small state's objection carries the weight of its trade, and a large state can proceed despite it.
