test(app-shell): StudioDesignSurface.flowCanvasChip-11665 reads the zh tooltip before the lazy studio catalogue lands, so Test UI goes red at random

Filed by the domain:ui#4 seat (session_01QsR2jTfvjNTaR29ehLk26T) from the #26579 dev's root-cause note. It is not a claim and carries no labels; it is left for triage.

Seen

CI run 40506346595 on PR #26685 at ac55d85e, Test UI (14/16) (job 122197139306). The one failure:

ui/packages/app-shell/src/views/studio-design/StudioDesignSurface.flowCanvasChip-11665.test.tsx:148, "zh: the header prints the flow label, no flow token, and the tooltip names the API name". It expected title="API 名称: nightly_digest" and received title="API name: nightly_digest".

The diff of #26685 touches no Studio, i18n or flow-canvas code. A single re-run turned the same job green (job 122202294554).

Cause (read, not instrumented)

The chip's title is t('designer.field.apiName', locale). That key lives in the studio i18n namespace, whose zh catalogue loads lazily (@object-ui/i18n namespaces/studio/index.ts, zh: () => import('./zh.js')). The test awaits only the caption testid and then reads title synchronously. If the zh chunk has not resolved, the title is still the en row. This is the ui/AGENTS.md test-discipline class: an unbounded module load inside a bounded window.

None of the 16 most recent failed CI runs (2026-10-27 02:45Z to 11:56Z) shows this test failing. It is intermittent; one plausible trigger is a shard-partition shift. That is unmeasured.

Wanted

Make the test deterministic. Either import the studio zh catalogue at module scope with the loader's own specifier, or await waitFor on the title. ⛔ Do not skip or quarantine it.

Dedupe searched: flowCanvasChip, studio catalogue, lazy zh, API 名称.

⛔ Not a claim, ⛔ not a dispatch.

p1: StudioDesignSurface.flowCanvasChip-11665.test.tsx:148 reads the zh tooltip before the lazy studio catalogue lands, so Test UI goes red at random (CI run 40506346595). A test suite that keeps going red gets fixed (「平台测试清单反复变红，肯定要修啊」). The test awaits the catalogue (findBy / a loaded signal). ⛔ No sleep, no retry wrapper, no quarantine.

You are the os-dev developer agent for exactly ONE card: #26692, 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/26692" -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 "Dispatch the ui lane" one message with your branch name and wait. Worktree objectstack-issue-26692 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=26692 --file=F --json run ONCE with output captured to a file (timestamps only as {{NOW}} / {{WAS:…}}). ⛔ 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, 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. Changeset in the root .changeset/ when a published package changes. ⛔ ui/.github/** and the root ci.yml are out of bounds. Hand back: when the PR and report are up, send the seat thread "Dispatch the ui lane" one message (PR, head sha, report gist); keep the thread open through review and drive CI to green.

Ruling (cannot be re-ruled)

Triage first grade 6444153925, verbatim: "The test awaits the catalogue (findBy / a loaded signal). ⛔ No sleep, no retry wrapper, no quarantine." The maintainer's word it cites: 「平台测试清单反复变红，肯定要修啊」.

Scope

File surface: ui/packages/app-shell/src/views/studio-design/StudioDesignSurface.flowCanvasChip-11665.test.tsx only (test-only fix; no source change). Then sweep: list every other test under ui/packages/app-shell/src/views/studio-design/** that asserts a zh string from the studio namespace synchronously after an await that does not wait on the catalogue; fix the same way in the same PR if ≤5 files, else report them as one finding.

PM mechanism assumptions (measure)

On origin/main d31329f1, the test awaits only findByTestId('auto-canvas-caption') (L134) and asserts title="API 名称: …" synchronously (L148). The established fix in this repo is a top-level await loadStudioCatalogue('zh') (used by feat(ui): lazy studio i18n namespace; designer.* and perm.* strings move into it (#25922 slice 1) #26593 and feat(ui): Studio inspector strings (page block, action, dataset, flow node, app nav, widget) move into the studio i18n namespace (#25922 slice S2) #26780); a findBy/waitFor on the title is the triage's other spelling. Pick one, say which.
Prove determinism: the card's red is intermittent, so show the test red when the zh chunk is withheld (ablation) and green with the fix.

Tier

No path-derived mandate. TIER_DEFAULT, effort medium (S, test-only). No changeset (test-only).

PR #26800 merged as 8eef9a8db4 (seat record: PR comment 6449821289). Two test files now preload the studio zh catalogue at module scope: StudioDesignSurface.flowCanvasChip-11665 (this card) and inspectorStrings.i18n-10804 (the same race, exposed by #25922 S2; Claim widened 6448012819). A 4000 ms loader delay keeps both green, and each goes red without its preload. pm:dispatched is removed with the close.
