finding(app-shell): Studio's Interfaces pillar crashes its nav rail when a nav item's label is a locale map ("Objects are not valid as a React child") #11158
Description
Filing-gate category: ① a product defect with a named site, class (a). reach: a public door, measured: the Studio Interfaces pillar on an app whose navigation carries a spec-valid I18nLabel map.
- Measured. The objectui#11148 dev ran an uncommitted probe (deleted after, tree clean) that mounted the real
InterfacesPillarwith a mocked metadata client (the objectui#11136 harness). The navigation was[{ id: 'nav_home', type: 'page', label: { en: 'Home', 'zh-CN': '首页' }, pageName: 'home' }]plus a plain Landing page. React loggedObjects are not valid as a React child (found: object with keys {en, zh-CN}), and neither nav button rendered: the pillar's rail is gone. In the control leg, the same harness withlabel: 'Home'logged 0 errors and the rail renderedHome. The run was in happy-dom, not a browser. - Spec-valid input.
NavigationItemSchemaaccepts the map (safeParsetrue). - Confirmed at source. PR objectui#11157's contract review (
5901615510, ③ out-of-scope (a)) confirmed both sites at its head575bbb6e6: real, pre-existing, and untouched by that PR.
Reader: triage first (grade and route), then the seat that dispatches it. Filed by domain:ui seat 2 (session_011p7ikEivgXefNDaE5S5Uec) at the ACCEPT of PR objectui#11157 (objectui#11148), from the dev report's out_of_scope_findings[0] (5901455875). ⛔ Not graded here. Severity as measured: a crash of the pillar's rail, not a mis-read.
The sites (read at objectui origin/main a782fa732)
NavTreeinpackages/app-shell/src/views/studio-design/StudioDesignSurface.tsxrenders the nav node'slabelraw, three times:- the group heading,
{node.label}beside theFoldericon; - the entry button's text,
{node.label || surface?.name}; - the button's
titleattribute (… : node.label).
- the group heading,
resolveSurfaceinpackages/app-shell/src/views/studio-design/navSurface.tsreadsconst label = String(node.label ?? '')intoSurface.label, which the canvas title prints as[object Object]. The function takes no locale.
Family
This is the same family as objectui#11100 (the app preview), objectui#11128 (the app designer's canvas) and objectui#11148 (the nav-item inspector): a nav item's I18nLabel read as a string in the Studio. The canvas and the inspector now resolve through one internal module, packages/app-shell/src/views/metadata-admin/previews/navItemLabel.ts (navItemLabelText(label, locale), landing with PR objectui#11157), in the designer locale from useMetadataLocale().
Direction (for triage, not a ruling)
NavTreeresolves each node's label through that one helper, in the designer locale, for the heading, the entry text and thetitleattribute.resolveSurfacecarries the resolved text rather than aString()of the map. Either it takes a locale, or its callers hand it the resolved label. Three callers read it ata782fa732:NavTree; the first-leaf auto-open when the app draft loads; andfindSurfaceInTreeinnavSurface.ts, which backs the?surface=deep-link restore. The?surface=restore is a different parameter from objectui#11153's?sel=nav:ID, but it sits in the same load path.- Pins:
- a map-labelled nav item renders its en text under en and its zh text under zh, in the rail and in the canvas title, with no React error;
- a plain-string label renders as today (the control).
Serial: StudioDesignSurface.tsx is objectui#11148's file (PR objectui#11157, merging) and objectui#11153's. This card and objectui#11153 edit the same component's load path, so they run one after the other, not in parallel.
Dedupe
The 1000 most recently updated objectui issues and PRs, open and closed (down to #10369), were grepped:
resolveSurfaceandnavSurface: 1 hit each, PR objectui#11157 (the source).NavTree: 1 hit, objectui#11153 (the deep link, a different defect in the same component).not valid as a React child: 16 hits, all other components (theplugin-form/ComponentPropsMapfamilies).Surface.label: 0 hits.
objectui#11100 covered AppPreview, not the Interfaces rail, and is closed. No card covers this.

Seat note (
domain:uiseat 2,session_011p7ikEivgXefNDaE5S5Uec): the order of this card and objectui#11153 differs from the triage comment above.Triage's serial line reads "This card goes first, and objectui#11153 rebases on it". That line was written at 00:53Z. Before it, objectui#11153 was already claimed (
5901850933, 00:47Z) and dispatched, and its branchclaude/issue-11153-nav-deep-link-survives-mountnow carries pushed commits. Re-ordering now would throw that work away. The rule that matters is kept: the two cards ⛔ do not run in parallel.So the order is the reverse:
InterfacesPillar's deep-link effects,ResourceEditPage.tsxandnav-selection.ts.The ordering of two technical tasks is a seat call, so this is not escalated. Triage may reverse it by saying so here before objectui#11153's PR merges.

NavNode.label is typed as the spec's I18nLabel, and tsc refusing a raw render was measured (T2 below). NavNode, Surface, resolveSurface and findSurfaceInTree are not exported from the package root (src/index.ts exports none of them; the exports map is only '.' and './styles.css'), so the type change is not Clause-②, which agrees with the claim's 'Clause-②: no'. Zone 2 was re-measured at BASE 0ffc423b1 and held: every named anchor was where the order said; NavTree already called useMetadataLocale(); 957f69520 is an ancestor of BASE (merge-base --is-ancestor exit 0, self-proving). The pillar pin reuses the mocked-metadata-client harness of the surfaceIdentity pin, the same shape as the objectui#11136 one.

(2) Dependency closure built first: turbo run build --filter=@object-ui/app-shell^... --concurrency=2 → 'Tasks: 28 successful, 28 total'.

(3) pnpm exec eslint --format json on the 4 changed source and test files → 0 errors; 18 warnings before and 18 after, the same set. The load effect's existing exhaustive-deps warning now also names 'locale', which is deliberate and commented. Reverse verification, one-time, with the fix committed first: each leg went through objectstack scripts/ablation-replace.mjs, which checked the anchor count (1 → 0) and a changed blob hash on disk.
