+/**
+ * [#25467 cut 22] Two view-container expansion members of
+ * `ObjectStackProtocolImplementation`, moved out of `protocol.ts` whole: the
+ * by-name read's answer for a view name no stored row holds but a stored
+ * container expands (`resolveRowlessExpandedView`, #21442/#21967: the list
+ * read's own rows, parse, expansion and selection), and the expansion of a
+ * container on another package's object under the container's own name
+ * (`expandUnderOwnName`, #21334).
+ *
+ * A MOVE, not a redesign. Each function below is the body of the
+ * `ObjectStackProtocolImplementation` method of the same name as it stood,
+ * re-indented one level and otherwise unedited: the same reads in the same
+ * order, the same `#5532` discrimination, the same selection, and the same
+ * names given to the expanded items.
+ *
+ * ## How the moved bodies reach the class
+ *
+ * The shape #23050 set for `rest-server.ts` (its `data-action-routes.ts`
+ * header carries the full reasoning), as `protocol-batch-data.ts` applies it.
+ * The class keeps both methods — the published `dist/*.d.ts` lists their
+ * names, docblocks and declared signatures — and each body is one literal of
+ * exactly the {@link ViewExpansionNamesHost} members it reads, each handed
+ * over as a closure, plus a `.call`. Every other reader of either method
+ * keeps calling the class method.
+ *
+ * What the bodies read of `protocol.ts`'s own module-level declarations they
+ * import from it; what they import from elsewhere, they import from where
+ * `protocol.ts` imported it. Nothing re-exports this module, so the published
+ * surface does not move.
