-Evidence anchoring, selector, resolution for citations.
+# 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`](../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`](../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.
