 - **FROM → TO.** `type: 'split'` → `type: 'tabbed'` (one tab per section) or delete the value for `simple`; delete each section's `pane` and the form's `splitSize` / `splitResizable`; declare `subforms` to edit child records beside the parent. `type: 'drawer'` or `type: 'modal'` → delete the value for `simple`, or write the layout you want. A list opens a clicked record as its `navigation.mode` says (the drawer by default), and the console's New and Edit entries open the record form themselves, sized by the form's `modalSize`.
 - **The one-line fix.** Delete the retired value and the three split-only keys. `os migrate meta --from 17` lists the edits for existing sources, and `--write` applies them. A stored `sys_metadata` row is converted when it is read (the `form-view-presentation-types-removed` conversion), so a form view saved with one of the three values keeps loading as a `simple` form.
 - **What the parse says.** Each retired value is refused by name with its prescription, for example "'modal' was removed from the form view `type` enum in @objectstack/spec 18.3.0 (ADR-0050) — …", at every form view door (a view's `form` and `formViews.*`, a form view item record, a flattened form overlay) and at `defineStack` as `STACK_SCHEMA_INVALID` / 422. `pane`, `splitSize` and `splitResizable` are refused on every layout. TypeScript rejects each at the authoring site. A misspelt value keeps zod's own message.
-- **Unchanged.** `drawerSide`, `drawerWidth` and `modalSize` stay declared: the console reads `modalSize` for its record dialog, and the `object-form` block's drawer container reads the other two. `splitDirection` left later in the same release, with the split renderer (#27159).
+- **Unchanged.** `splitDirection`, `drawerSide`, `drawerWidth` and `modalSize` stay declared: the console reads `modalSize` for its record dialog, and the React `ObjectForm` block contract still takes the other three from this schema until its renderer follows.
 
 The console (`@object-ui/app-shell`): Studio's New View form offers the three form layouts only. It offered all six, and a form view created with `split`, `drawer` or `modal` would now be refused when saved.

 - **`@object-ui/plugin-form`.** `ObjectForm` renders the `simple`, `tabbed` and `wizard` layouts only; a `formType` of `drawer` or `modal` on a node handed straight to `<ObjectForm>` now renders the inline form, and the host opens its own drawer or dialog around it (the console's New and Edit dialogs already mount `ModalForm` themselves). The registered `object-form` block routes `drawer` and `modal` through the new internal `ObjectFormContainer`, which hands the node to `DrawerForm` or `ModalForm` as before. `SplitForm`, `SplitFormProps` and `SplitFormSchema` are no longer exported, and the block no longer publishes the `splitDirection`, `splitSize` and `splitResizable` inputs. FROM `import { SplitForm } from '@object-ui/plugin-form'` → TO a `TabbedForm`, or the `form` renderer's `fieldPanes` for a host that composes panes itself.
 - **`@object-ui/types`.** `ObjectFormSchema.formType` is `'simple' | 'tabbed' | 'wizard' | 'drawer' | 'modal'`, and its `splitDirection` / `splitSize` / `splitResizable` are the spec's tombstones by reference; the section `pane` member is gone.
 - **Console.** Studio's page-block inspector no longer offers `Split` for an `object-form` (its `engine.inspector.pageBlock.option.formType.split` string is removed from `@object-ui/i18n`), the record page passes no split keys, and a view whose `type` is not one of the three form layouts is no longer taken for a form (`@object-ui/console`).
+- **Supersedes one line of the form view `type` entry (#27155).** That entry says `splitDirection` stays declared; in this release it leaves too.
 - **Unchanged.** `drawerSide`, `drawerWidth`, `modalSize` and `modalCloseButton` keep their readers: the block's drawer and modal containers. The enforce-or-remove question for `drawerSide` / `drawerWidth` on form views stays on #27153.
