Relations survive an unexposed source · case 02

Relations survive an unexposed source.

Case contract

Input [nodes,requests] with nodes [document,id,exposed,defunct] and requests [source_doc,source_id,target_doc,target_id,kind]. Allowed kinds details, controls, describedby. Resolve in document-scoped ID space, reject missing/hidden/defunct sources or targets, self edges, cross-document edges and unsupported kinds. Dedupe identical edges preserving request order. Return [source_id,kind,target_id]. IDs may repeat in different documents. Source and target visibility are direct snapshot flags, not ancestry.

Why this case matters

Offline accessibility bridge model with explicit policy; useful for testing semantic API adapters independently of browser implementations.
