ShapeView

One declared shape, as returned by the API and MCP surfaces.

This is the readback RetrievedShape projected onto a wire shape: HomeAnchor and KindOwner
are rendered as their (table, id) scalar pairs (the same split ArtifactView uses for
kind_owner_table/kind_owner_id) so a consumer that does not share the Rust types still gets a
self-describing response.
