finding(app-shell): Studio's app designer in design mode names a nav item whose label is a locale map "Item N" (AppNavCanvas navLabel reads the label only as a string), while the preview beside it shows the resolved text #11128
Description
Filing-gate category: ① a product defect with a named site, class (a). reach: measured. The objectui#11100 dev ran a probe at PR objectui#11127's head cbe37f8b2 (not committed): AppPreview in editing mode, locale zh-CN, one nav item labelled { en: 'Accounts', 'zh-CN': '客户' }. The design canvas row read Item 1, while the landing line above it read 客户 (PR objectui#11127's fix).
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#11127 (objectui#11100), from the dev report's out_of_scope_findings (5894787139). That PR's contract review (5895011457, ③ d) confirmed it at the head: pre-existing, and the file is byte-identical at base and head. ⛔ Not graded here.
The site (read at objectui origin/main 0ecaa7dbb)
packages/app-shell/src/views/metadata-admin/previews/AppNavCanvas.tsx:
navLabel(it, i)(:164–:169) keeps a label only whentypeof l === 'string', and otherwise answers the positionalItem ${i + 1}. The spec types a nav item'slabelasI18nLabel, a string or a per-locale map.- Read only, not measured:
renameItem(:260–:264) writes{ ...cur, label: nextLabel }, a plain string. Renaming a map-labelled item in the canvas would therefore replace the whole map, and every other locale's text would be lost. Triage should rule on this in the same card.
Direction (for triage, not a ruling)
- It is the same family as objectui#11100 (a locale-map nav label read as a string), which PR objectui#11127 closed for the preview. Resolve the canvas label through the spec's
resolveI18nLabel(label, locale)in the designer locale, asAppPreviewnow does, and keepItem Nonly for a label that is truly absent. - For the rename path: decide whether an inline rename edits the current locale's entry of a map, or refuses and routes the author to the map editor. ⛔ It must not silently replace a map with a string.
- Pins: a map-labelled item under en and zh in design mode shows the resolved text; a plain string is the control; and the rename rule chosen for a map-labelled item.
- Serial: objectui#10862 (
pm:queue) moves this preview family's chrome strings.

Display now resolves the `I18nLabel` in the designer locale through the spec's `resolveI18nLabel`, the resolver AppPreview uses. The locale is the canvas's own `useMetadataLocale()`, threaded as a prop into NavCardTree and NavCard, and NavCard no longer calls the hook itself. A new `renamedLabel` helper leaves a plain string (or an absent label) as a string; on a map it writes only the designer locale's entry (exact tag, else bare language, else a new exact-tag entry) and keeps every other entry. The truly-absent fallback reads the new `engine.appNav.item` row through `tFormat`: en `Item {n}` renders byte-equal to the old text, zh is `导航项 {n}`. Zone-2 assumption 2 is falsified in part: the designer locale is `en-US` or `zh-CN`, not `en`. The exact-then-base key choice is what makes an English rename of an `{ en, zh-CN }` map write `en` (the key display reads) instead of adding `en-US`, and the third ablation pins that.
