+
+fix(types,layout): nav item type `component` joins `NavigationItemType` and its zod enum — objectui#2918
+
+The renderers have carried a full `type: 'component'` implementation (Phase 3b:
+`componentRef` colon-split to `/component/<ns>/<name>`, `params` serialised as
+querystring, `metadata:*` special-cases) — but the vocabulary never gained the
+member, and `@objectstack/spec` has had `ComponentNavItem` all along. The zod
+enum was the part that bit: `NavigationItemTypeSchema` rejected
+`type: 'component'` at validation time, so authors could not declare one and
+the renderer half was unreachable — dead on arrival rather than dead code.
+
+- `NavigationItemType` and `NavigationItemTypeSchema` gain `'component'`;
+  `NavigationItem` gains the fields the renderer consumes, `componentRef` and
+  `params` (also used by `type: 'page'`), mirroring spec's `ComponentNavItem` —
+  declared in zod too, so parse no longer strips them.
+- The `(item as any).componentRef` / `params` casts in `NavigationRenderer`
+  and `AppSchemaRenderer` become typed access.
+- `NavigationDesigner`'s exhaustive type-meta map gains a `component` badge
+  (new `appDesigner.navTypeComponent` key in all 10 locales).
+- `@object-ui/layout` gains `type-check` (src + tests) with the #2915 `paths`
+  override; its DEBT entry in `check-type-check-coverage.mjs` is deleted.
