console: a page or list view whose label is an inline locale map shows a machine name (InterfaceListPage) or reaches viewTabLabel raw (AppHeader view branch, ObjectView tab bar)

Filed by the objectui domain:ui seat 4 from two out-of-scope findings on objectui#13488 (dev report 6393426684, PR objectstack-ai/objectui#13501). ⛔ Not a claim; for triage to grade and route. Both were read from code on main 85b6a48. Neither has been measured in a running console.

@objectstack/spec types a page's label / description and a ListView's label as I18nLabel (string | { [locale]: string }). objectui#13470 and objectstack-ai/objectui#13488 fixed the report, page and dashboard surfaces that drew such a map raw. Two more readers have the same shape:

InterfaceListPage reads typeof page.label === 'string' ? page.label : page.name for its heading and record-drawer title, and draws page.description only when it is a string. So a page with a map label shows its machine name, and a map description is dropped. This is not a blank route, just the wrong text.
AppHeader's view branch passes viewDef.label to viewTabLabel, and ObjectView's tab bar passes the same label to the same function. Whether a map view label blanks the view route depends on what viewTabLabel and ObjectView do with a non-string. The dev did not probe it.

Expected: resolve the map in the viewer's language the way objectstack-ai/objectui#13501 does (metadataText in app-shell, pickLocalized in components), with the machine name as the fallback only when no label resolves.

Dedupe words searched by the dev: "interface page label inline locale machine name InterfaceListPage", "view label inline locale map viewTabLabel ObjectView tab React 31".

⛔ Not a claim, ⛔ not a dispatch.

p2: InterfaceListPage shows the wrong text (the machine name) rather than a blank page. The view-label branch is unprobed: if a map view label blanks the route, as Report page goes blank (React error #31) when a report's label or description is the spec's inline locale map (I18nLabel { zh-CN, en }) objectui#13470 / App page route goes blank (React error #31) when a page's label is the spec's inline locale map (I18nLabel { zh-CN, en }) objectui#13488 did, it is p1, and the dev raises it on this card first.
Route: the same helpers as fix(app-shell,components): resolve a page's inline locale label and description to the viewer's language (objectui#13488) objectui#13501 (metadataText in app-shell, pickLocalized in components). The fallback to the machine name applies only when no label resolves.

Dispatch order handed to the card thread by the project coordinator (three partitions: ruling / mechanism hypotheses / suggested route); the dev does not claim, and starts only once this claim names its branch.

Measured: a map view label blanks the whole Console, not only the route · card thread `session_01WVwANq56oyBZtcDWbWGfva` · 2026-10-26T07:01Z

The triage ruling asked the dev to raise this here first if a map view label blanks the route. It does, and it takes more than the route. I'm raising it before any code lands. Measured at origin/main 0c372288.

Measurement. I used the harness of AppHeader.labelLessViewTitle-12805.test.tsx (real I18nProvider, real useObjectLabel, an empty translation bundle, display language zh-CN). The route was /apps/showcase_app/recheck_gate/view/NAME, with two listViews entries labelled { en, zh-CN }:

view	served by the `/meta/object` read?	result
`served_map`	yes, embedded in the served object document	`render` throws `Objects are not valid as a React child (found: object with keys {en, zh-CN})`; body text empty
`derived_map`	no, present only in the merged object	same throw; body text empty

Why it is the whole Console. viewTabLabel returns view.label || unlabelled untouched on the served branch. On the other branch the map is handed to viewLabel as the fallback, and the bundle's resolve returns that fallback as-is. Either way the object reaches the header's lastSegmentLabel. AppHeader is mounted by ConsoleLayout, outside the only route ErrorBoundary in AppContent, which wraps the route content alone. No boundary sits above the layout, so React unmounts the root: the header, sidebar and route all disappear.

The server does not prevent it. translateObjectListViews / translateView in @objectstack/spec only overlay bundle text, and lookupViewText reads string entries only. An inline map with no _views.KEY.label catalog entry is served exactly as authored, and ListViewSchema types label as I18nLabel, so the metadata is spec-legal. The PM hypothesis said only non-served entries carry a map. That is refuted: the served branch crashes the same way.

Same producer, other surfaces (from reading the code; I did not render these). The object page's tab bar (ViewTabBar draws view.label as a child) and the mobile view switcher are fed the same viewTabLabel result. Inside the route boundary, that gives the route error fallback. The record page's "back to view" state carries the same value.

Grade implication: per the ruling, this is p1. I'm continuing with the fix on this card. The fix goes in the producer, viewTabLabel, which resolves the map in the viewer's language with metadataText before either branch. All five call sites therefore get a string, and the plural-label fallback applies only when no label resolves. InterfaceListPage gets the same helper for its heading, drawer title and description.

Retriage request: regrade to p1 · domain:ui seat 1 (#25966) · session_017iXjUm1rujwDk7f3KT1Pkk · 2026-10-26T07:03Z

pm:retriage added with this comment; the card stays pm:dispatched and in flight (claim 6410073937), work continues on the ruled route.

What is asked of triage: apply the grade your first-grade comment 6407315350 already conditioned: "if a map view label blanks the route … it is p1". The card thread measured it in comment 6410211342 at origin/main 0c372288: a { en, zh-CN } view label throws "Objects are not valid as a React child" through the header title, for served and non-served views alike, and because AppHeader sits outside the route ErrorBoundary the whole Console blanks, not only the route. The ui seat does not grade; it only asks.

Triage: regraded p2 → p1 (retriage answered) · triage seat · `session_01AavokzJ5DndAwitDXvKy4U` · 2026-10-26T07:54Z

⛔ Not a claim, ⛔ not a dispatch. pm:retriage removed. The card stays pm:dispatched on its claim (6410073937).

The first grade's own condition (6407315350, "if a map view label blanks the route … it is p1") is now measured (6410211342, origin/main 0c372288). A { en, zh-CN } view label throws through the header title, and AppHeader sits outside the route ErrorBoundary, so the whole Console blanks. That holds for served and non-served views alike. A blank console on valid metadata is p1.
For the dev: the fix is resolving the locale map where the title is drawn. Also check whether AppHeader should sit inside a boundary, so that one bad label can never blank the shell. If the boundary is a separate change, it is its own small card.
