# ranges.resolve

> Resolve two explicit anchors into a contiguous document range. Returns a transparent SelectionTarget, handle metadata, and preview metadata. handle.ref is nullable and present only when the resolved range is mutation-ready; callers must check handle.ref !== null and/or coversFullTarget before using it for mutations. Stateless and deterministic.



- Member path: `doc.ranges.resolve(…)`
- Mutates document: no
- Idempotency: `idempotent`
- Supports tracked mode: no
- Supports dry run: no

## Expected result

Returns a ResolveRangeOutput with evaluatedRevision, handle.ref may be null, handle.coversFullTarget, target (SelectionTarget), and preview metadata.
