+# Saved view
+
+A record exposed through `mdbase.view` stores shared query scope and one or more
+stable named views. Each named view resolves to the query model in Chapter 11.
+Optional `presentation` metadata is advisory and does not alter headless query
+results.
+
+Implementing this contract is how a collection declares which of its records
+are saved views. A tool that advertises `view_records` discovers and executes
+views through this contract's type implementations, not through a reserved type
+name, path, or frontmatter value.
+
+This artifact is passive. Implementing it grants no authority to read, execute,
+or modify any record.

+# View
+
+A view record stores shared query scope and one or more stable named views.
+Tools that support saved views discover these records through the `mdbase.view`
+contract and run each named view as an ordinary query.
+
+This type belongs to your collection once installed. You can rename fields or
+change how records are matched, as long as the `implements` mapping still
+points each contract field at the right frontmatter field.

+# View
+
+A view record stores shared query scope and one or more stable named views.
+Tools that support saved views discover these records through the `mdbase.view`
+contract and run each named view as an ordinary query.
+
+This type belongs to your collection once installed. You can rename fields or
+change how records are matched, as long as the `implements` mapping still
+points each contract field at the right frontmatter field.
