+
+The registered `object-view` renderer reads a named grid view's own grid members off the named view (objectui#10885).
+
+`object-view` is registered without a `renderListView`, so an authored node, and the Studio's view preview (which renders a stored view through `SchemaRenderer`), draws a grid view as the `object-grid` node `ObjectView` builds for `ObjectGrid`. That node read `columns`, `filter`, `sort`, `grouping` and `rowColor` off the active named view and nothing else, so a stored or authored grid view's `rowHeight`, `pagination` and the rest were accepted and not shown.
+
+It now also reads, off the active named view first, ten members the protocol declares under the same name on both a named view and `object-grid` and that `ObjectGrid` reads: `pagination`, `selection`, `rowHeight`, `resizable`, `searchableFields`, `conditionalFormatting`, `rowActions`, `bulkActions`, `bulkActionDefs` and `exportOptions`. `pagination` and `selection` still fall back to the node's `table` when the named view omits them; the others have no node fallback on this path, as before. Three other members declared on both, `label`, `data` and `navigation`, are still not read off the named view on this path.
+
+A named view's `hiddenFields` is applied the way the protocol composes it: the hidden fields are removed from the column projection the grid receives. Only a declared projection is narrowed; with no `columns` anywhere the grid still derives its own.
+
+What moves: only a grid view that authors one of these members. A named view that carries none of them renders exactly as before, and the host `renderListView` delegation is unchanged.
+
+`Clause-②: no` — no declared type, accepted key or published export moves. A renderer starts honouring members the spec already declares on a named view and the grid already reads.

+ * objectui#10885 member 1 — the Studio view preview shows a stored grid view's
+ * own grid members.
+ *
+ * `ViewPreview` injects the stored view body as a named `listViews` entry and
+ * renders it through `SchemaRenderer`, which resolves the REGISTERED
+ * `object-view` renderer: `ObjectView` with no `renderListView`, so a grid view
+ * lands on route 2, the `object-grid` node `ObjectView` hands `ObjectGrid`.
+ * Before this card that node read `columns`, `filter`, `sort`, `grouping` and
+ * `rowColor` off the named view and nothing else, so a stored view's
+ * `rowHeight` and `hiddenFields` were accepted and dropped from the preview.
+ *
+ * Everything here is the real stack: the real `ViewPreview`, the real
+ * `SchemaRenderer` and registry, the registered `object-view` renderer and the
+ * real `ObjectGrid`. The readings are the rendered DOM.
+ *
+ *   - `rowHeight` — `ObjectGrid` draws its row-height control only when its
+ *     node carries `rowHeight`, titled with the resolved mode.
+ *   - `hiddenFields` — the protocol's column composition: `columns` projects
+ *     and `hiddenFields` subtracts. The hidden column's header is not drawn.
+ *   - Lit control — `columns` off the SAME named view was already honoured on
+ *     route 2: a field the view does not project is not drawn, and a projected
+ *     one is.
