Each citation links to the sentence it supports in the citing article.
Mechanisms¶
- Overlap Detection Join
- Where the partition can instead be enforced declaratively — a uniqueness or exclusion constraint in the database — you don't need the join at all; the join is precisely what you run when membership is computed or imported rather than constrained, so exclusivity can't be guaranteed by construction.
This sourceExplains that uniqueness and exclusion constraints declaratively reject rows that violate configured equality or overlap rules.

Verification¶
Does it exist? Not checked yet. This entry carries no identifier to resolve. It was extracted from the citation as written in the article, normalized, and deduplicated against the rest of the registry.
Does it back the claim? Not recorded. The single citation of this work carries no recorded support check.
Support is checked per citation rather than per work — the same source can be cited soundly in one article and wrongly in another. Per-citation recording began recently, so a citation with no recorded check is a gap in the record rather than evidence it went unchecked.
