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
PartialClaimed · partialDefinition · 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 releaser's own restriction set governs its own artifact and each data producer decides whether their content stays in the store, so there are genuinely many written regimes running side by side with no merging step. But the sphere is a piece of property, a set of weights or a document, rather than a community governing its internal affairs. Those living under a given license are whoever downloaded it, and they took the terms rather than making 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
This is the closest thing in the cell to a working allocation rule: the license attached to an artifact is what says which restriction set governs its use, and it is legally operative rather than descriptive. What is missing is the case Savigny built the rule for. A derivative work combining two differently restricted models, or a user bound at once by a license and by national law, gets no answer, and SILO makes the same gap plain by invoking two legal regimes at once without any rule saying which reaches a given query.
Mutual veto and proportionality
PartialClaimed · partialDefinition · 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
The opt-out gives a data producer a real check on somebody else's system: content comes out of the store and the model's behavior changes without retraining, because the store is only queried at inference. But it is exit rather than consent, exercised one contributor at a time over one's own material, so no body of data producers can withhold agreement from a decision that affects them all. Proportionality is absent altogether, nothing scales anyone's voice to their stake, and on the licensing side those the restrictions protect have no say of any kind.
