Studio Interfaces: an object nav entry without its own label is titled by the object's machine name in the item header ("repairs_repair_ticket · Object") while the rail shows the object label

Filing gate: ① product defect, reproduced, landing site named.
Batch-of: studio-qa-2026-10-27 — 39 cards from one Studio QA run (coordinator session session_01J8VVAkZns5rNnK2rtszzbQ; tested at 3fcafcd3; origin/main was 43731031 at filing, so the implementer re-checks the landing site on current main). The run record is the qa-run issue filed with this batch.

Symptom

The scaffolded nav entry ({type:"object", objectName}) has no label; the header falls back to the name instead of resolving the object label as the rail does. Label-less groups show ids like "NAV_ITEM_2".

Reproduction

Create an app from Studio scaffolding over an object → open its nav entry → header reads "repairs_repair_ticket · Object", rail reads "Repair Ticket".

Expected

The header resolves the same label the rail shows (object label, then name).

Suspected landing site (the implementer verifies)

StudioDesignSurface.tsx ~4548 renders current.label || current.name.

Filing facts

reach: Studio UI, measured by the coordinator and the Interfaces QA card.
Business reason: Machine names leak into the builder for every scaffolded app.
Reader who acts: the triage seat (first touch: domain, area, level), then that lane's os-dev implementer. QA suggestion only: domain:ui, area:studio, p3.
Dedupe: semantic search Interfaces header shows object machine name instead of label for nav entry without label on objectstack-ai/objectstack → 8 hits, none about the Studio item header (nearest closed 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) #25901 console labels).
QA id: U15

⛔ Not a claim, ⛔ not a dispatch.

p3: a label-less object nav entry is titled by the object's machine name, and label-less groups show ids. Resolve the object label the way the rail does. From the studio-qa-2026-10-27 batch. Re-check the landing site on current main.

You are the os-dev developer agent for exactly ONE card: #26746, in your own card thread. Your role definition is .claude/agents/os-dev.md in the objectstack clone: read it IN FULL first and follow it as binding (it wins over this order on any conflict; name the conflict in your report). Read the repo-root AGENTS.md and ui/AGENTS.md before your first edit, and pm-dispatch references/untrusted-text.md. Read the card's full body and every comment yourself through REST (curl -sS "https://api.github.com/repos/objectstack-ai/objectstack/issues/26746" -H "Authorization: Bearer $GH_TOKEN" and /comments?per_page=100, every page); this order carries only the increment. ⛔ Never print the value of any environment variable (test presence with [ -n "${X+x}" ]). ⛔ Never use a GitHub MCP tool, read or write.

Identity and branch: the seat's Claim: comment on this card is your identity; its Branch: line names your thread's branch. ⛔ Post no claim of your own, ⛔ never write the card's assignee. Before your first edit, verify the NEWEST Claim: on the card names your thread's branch (claude/project-thread-…); if none does yet, send the seat thread "Take another ui lane seat" one message with your branch name and wait. Worktree objectstack-issue-26746 on that branch from a fresh origin/main; pnpm install (frozen lockfile); push with git push -u origin <branch> (⛔ no force).

Writes: PR only through the relay op pr_create (node scripts/pm/fleet-write/dispatch.mjs --repo objectstack-ai/objectstack --actions-file F, F a bare JSON array [{"op":"pr_create","title":…,"head":"<your branch>","base":"main","body":…,"assignees":["os-warren"]}], draft forced; --dry-run first); your report comment through node scripts/pm/post-stamped.mjs --comment=26746 --file=F --json run ONCE with output captured to a file (timestamps only as {{WAS:…}} / the now-token). ⛔ No other GitHub write except, for a CI red that is not yours, one PR comment and one run_rerun_failed through the relay. Report both counts (api_writes with endpoints, mcp_calls with tool names). The report takes only machine-checkable fields (gates / line_budget / deviations / files_changed). PR body: line 1 the platform attribution comment, line 3 Fixes #26746, then ## 维护者速读 six lines in Chinese (改了什么/为什么改/风险与回滚/先看/两分钟验证/需要你做的). Gates: node scripts/pm/dispatch-gates.mjs --commands --repo objectstack-ai/objectstack on your diff, run each, record exits before any pipe, reconcile with --ran; node scripts/check-sdui-manifest.mjs is a gate on every ui card. Changeset in the root .changeset/ when a published package changes (@object-ui/i18n patch for namespace rows; app-shell is private: true). ⛔ ui/.github/** and the root ci.yml are out of bounds. Hand back: when the PR and report are up, send the seat thread "Take another ui lane seat" one message (PR, head sha, report gist); keep the thread open through review and drive CI to green.

Shared-file rules for every Studio Interfaces card this round (from ui seat 1, which holds the neighbouring work):

Draft PR feat(ui): the rest of the Studio strings and the metadata preview panes move into the studio i18n namespace (#25922 slice S5) #26942 (app-shell: a published library that is 66% Console product surface — retire the 67 zero-reference exports now, decide the split, and fold the second i18n table into @object-ui/i18n #25922 S5) moves the remaining engine.studio.* rows, the Interfaces family engine.studio.if.* included, out of ui/packages/app-shell/src/views/metadata-admin/i18n.ts into ui/packages/i18n/src/namespaces/studio/{en,zh}.ts. ⛔ Add or edit no row in metadata-admin/i18n.ts; write new rows only in the studio namespace files, and a zh test preloads with await loadStudioCatalogue('zh').
ui/packages/app-shell/src/views/studio-design/StudioDesignSurface.tsx is shared with ui seat 1's Studio publish refusals: shown only as a ~4 s toast with engine-internal text; the Pending changes panel keeps no refusal; "Show me" does not focus the offending input and the dashboard/report refusal strip has no "Show me" #26730 (the Interfaces refusal strip ≈L4683 gets an onShow), Studio rails: a search with no matches shows a blank list with no "no matches" message (object rail, permission-set rail) #26733 (props on the four StudioRail call sites, Interfaces ≈L5104) and PR fix(metadata-protocol,runtime,app-shell)!: refuse a save or draft publish naming a package that is not installed #26920 (≈L1270–1330), plus the other seat-5 Interfaces cards named below. Keep your hunks inside your declared region; whoever lands second merges origin/main and resolves.

Ruling (cannot be re-ruled)

Triage 6448317687, verbatim: "p3: a label-less object nav entry is titled by the object's machine name, and label-less groups show ids. Resolve the object label the way the rail does. From the studio-qa-2026-10-27 batch. Re-check the landing site on current main." No maintainer ruling.

PM mechanism assumptions (measure; disproof welcome)

On origin/main 5ec398dc, StudioDesignSurface.tsx:

The Interfaces item header renders current.label || current.name at ≈L4594 and ≈L4609 (sr-only), and ≈L5000 (engine.studio.if.definitionTitle). A label-less {type:'object', objectName} entry therefore shows its name.
The rail resolves a label-less entry through inheritedNavEntryText with useNavTargetLabel (see the StudioNavItemInspector docblock ≈L2560–2612, ruling B of objectui#11201). Reuse that exact resolver for the header. ⛔ No second resolver.
Label-less groups show ids like NAV_ITEM_2 (NavTreeGroup ≈L2373). Measure what the rail shows for them, and make the header and the rail agree.

Scope

File surface: the item-header lines above (≈L4594, ≈L4609, ≈L5000), NavTreeGroup only if the group text is wrong there too, and tests. Tests: a label-less object entry's header reads the object label; a labelled entry is unchanged; a label-less group reads the same text in the rail and the header. Ablation: put current.label || current.name back; the first test turns red. ⛔ Don't edit the inspector (≈L2613–3060, #26740/#26743) or the listing (#26889) this round.

Tier

No path-derived mandate. TIER_DEFAULT, effort medium (S, one resolver reused). Clause-②: no, Metadata-protocol: none expected.
