Local sections, overlaps, gluing status, and obstruction review. Paper-level causal claims remain local sections until population, intervention, mechanism, and limitation maps agree on an overlap.

Restriction And Gluing

Overlap	Contexts	Status	Decision Surface
article_claim	Source / Claim extraction	glues	evidence spans preserve article ids
claim_edge	Claim extraction / Causal structure	qualified	mechanism and dose fields need typed promotion
edge_gate	Causal structure / Admission gates	review	hypotheses are not settled intervention proof

Democritus preserves scoped causal claims while keeping unsupported mechanism and dose generalizations as visible obstructions.
