finding(app-shell): Studio's nav-item inspector shows a locale-map label as "[object Object]", and one keystroke writes a plain string over the whole map

Filing-gate category: ① a product defect with a named site, class (a), loss of authored metadata. reach: a public door, measured. The objectui#11128 dev ran an uncommitted probe at PR objectui#11146's head 9d2fb10d8. It rendered the Studio app pillar's nav-item inspector (StudioNavItemInspector) with label: { en: 'Accounts', 'zh-CN': '客户' }. The Label input showed [object Object], and one keystroke wrote the plain string Customers over the whole map, so the zh-CN text was lost.

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#11146 (objectui#11128), from the dev report's out_of_scope_findings[0]. That PR's contract review (5899177331, ③ c) confirmed it at the head, in the same family as objectui#11128, and asked for a sibling card. ⛔ Not graded here.

The site (read at objectui `origin/main` `385ebc5c6`, `packages/app-shell/src/views/studio-design/StudioDesignSurface.tsx`)

StudioNavItemInspector (:1426) reads const curLabel = String(node.label ?? node.title ?? node.name ?? '') (:1464), so a map becomes [object Object]. It also reads title and name, which are not nav-item keys.
The Label input writes patch({ label: e.target.value }), which replaces a map with a string.
The inspector is rendered beside the app designer's canvas in the Studio app pillar. After PR objectui#11146 the canvas keeps a map on rename while this inspector, next to it, still deletes it.

Direction (for triage, not a ruling)

This is objectui#11128's rule, applied to the second editor of the same label:

Display resolves through the spec's resolveI18nLabel(label, locale) in the designer locale.
An edit writes the designer locale's entry of a map and keeps every other entry, using the same key choice as PR objectui#11146's renamedLabel (exact tag, else bare language, else a new exact-tag entry), ideally by sharing that helper so the two editors cannot disagree.
A plain-string label stays a string.
title / name are not read as a label.

Pins: a map label shows the resolved text under en and zh; an edit under zh changes only zh-CN; a plain string edits as today.

Serial: StudioDesignSurface.tsx is also objectui#11136's file (the Interfaces pillar's inspectors), a different component in the same file.

Path: studio — a translated label survives an edit | 缺项 (Studio's nav-item inspector shows a locale-map label as [object Object], and one keystroke writes a plain string over the whole map, so every other locale's text is lost) | P2

Triage: first grade — `bug` · `priority:p2` · `domain:ui` · `area:studio` · `pm:queue`. Direction: objectui#11128's rule on the second editor, through the same helper, so the canvas and the inspector cannot disagree

Triage: lands in packages/app-shell/src/views/studio-design/StudioDesignSurface.tsx (StudioNavItemInspector) ⇒ domain:ui. It is the sibling objectui#11128's contract review asked for.

Triage seat (objectstack-wide, seat post objectstack-ai/objectstack#6015) · session_01AavokzJ5DndAwitDXvKy4U · 2026-09-29T23:01Z. ⛔ Not a claim, ⛔ not a dispatch.

Why p2. It takes objectui#11128's grade (p2): the same loss of authored translations, on the second editor of the same label.

It is not p1 because the input shows [object Object] before any keystroke. So the author is told the label is not what was authored.
It is not lower because after PR objectui#11146 the canvas beside it keeps the map, while this inspector still deletes it.

Direction.

Display. The inspector resolves the label through the spec's resolveI18nLabel(label, locale), in the designer locale, the way the canvas does.
Edit. An edit writes only the designer locale's entry of a map and keeps every other entry. A plain-string label stays a string.
- It uses PR objectui#11146's renamedLabel (previews/AppNavCanvas.tsx:198, module-private today), moved to one module both editors import.
- ⛔ No second copy of the key choice (exact tag, else bare language, else a new exact-tag entry).
Keys. title / name are not read as a nav item's label.
Pins:
- a map label shows the resolved text under en and under zh;
- an edit under zh changes only zh-CN;
- a plain string edits as it does today;
- PR objectui#11146's canvas pins stay green.

Serial. StudioDesignSurface.tsx is also PR objectui#11152's file (objectui#11136, ACCEPTed and open) and objectui#11153's. They are different components in one file: whichever lands second rebases. The dispatching seat reads PR objectui#11152's state at claim.

Premise verified at origin/main 3a0e7ab05: the String(label ?? title ?? name) read and the patch({ label: e.target.value }) write were present in StudioNavItemInspector, and NavigationItemSchema accepts a map label (safeParse true for { en, zh-CN }). Reach note for the seat: loading a map-labelled app into the Interfaces pillar crashes its left rail before nav-edit mode is reachable (out_of_scope_findings[0]), so today the inspector meets a map in the full pillar only when the map arrives while nav-edit mode is already on (not measured).",

item	reading
the change	`StudioNavItemInspector` shows a nav item's `I18nLabel` resolved in the designer locale (`useMetadataLocale()`), through the spec's `resolveI18nLabel`, the way the canvas does. Its Label input writes only the designer locale's entry of a map, and keeps every other entry. A plain-string label still edits to a plain string. `title` / `name` are no longer read as the label
one key choice	PR objectui#11146's `renamedLabel` moved verbatim (byte-identical body) out of `AppNavCanvas.tsx` into one internal module, `previews/navItemLabel.ts`, beside `navItemLabelText` (the resolve step). The canvas and the inspector both import it. It is not in the package root and has no `exports` entry
object bind	A real label is kept as authored, and a placeholder adopts the object's label through `renamedLabel`. This departs from the seat's own Zone-2 wording, whose literal reading writes a resolved string over a map (ablation leg A3). The review (① 5) judged the implemented rule right and inside the card
tests	`StudioDesignSurface.navItemInspectorLabelMaps-11148` (8 tests) renders the real exported inspector under `I18nProvider`. It pins: en and zh display of a map; a zh edit that changes only `zh-CN`; one new entry, not one per keystroke, through a stateful harness; the plain-string control; `title` / `name` not read; a bind that keeps a real map. PR objectui#11146's canvas pins are byte-unchanged and green. Ablation: A1 turns 4 cases red, A2 3, A3 1
changeset	`'@object-ui/app-shell': patch`; `Clause-②: no` (no accepted set or export moves; the helper move is internal)

closing keywords	`Fixes #11148` only

Out of scope, one line each:

Studio's Interfaces pillar crashes its nav rail on a locale-map nav-item label: NavTree renders node.label raw, and resolveSurface in navSurface.ts stringifies it. The dev measured this at a public door, through the real InterfacesPillar with a plain-string control. The review confirmed it real at the head, pre-existing and untouched here. filed objectui#11158. Until it lands, this card's fix is reachable end to end only when a map arrives after nav-edit mode is on. objectui#11153 is ordered with it on the same load path.
The dev's note that an AppNavInspector component "no longer exists" is wrong at the head. inspectors/AppNavInspector.tsx exists and is registered in inspectors/index.ts, so the comments naming it are accurate. dropped — the premise is false. The PR body's Acceptance-notes sentence repeating it is inaccurate. The body is not PATCHed: this line is the correction of record.
