evidence-anchor

Selector creation, resolution, and the DocumentViewerAdapter contract that every document viewer in the workspace implements.

MVP status: INTENT only

During the citation-evidence MVP, code lives upstream in citation-evidence under src/anchor/. This repo currently holds INTENT.md describing what will move here. Contract changes belong in citation-evidence/wiki/SharedContracts.md, not here.

Per the dependency map, anchor depends on shared/ and engine/ only; nothing in binder/, source/, or work/ may flow back into it.
