+/// <summary>
+/// Document filter that fixes security scheme references after document generation.
+/// </summary>
+/// <remarks>
+/// In Microsoft.OpenApi v2, <see cref="OpenApiSecuritySchemeReference"/> requires a resolved
+/// <c>Target</c> to serialize correctly. References created without a host document (as in
+/// operation filters) serialize as empty objects. This filter re-creates all security scheme
+/// references with the document context so they resolve properly during serialization.
