   You are the os-dev developer agent for exactly ONE card: #27216, 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/27216" -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 a third ui lane seat" (cmsg_01U5RdnAAmkSQmZbqh6FtqZ8Uc2nCvWvLyYyaVYaUhakpJ) one message with your branch name and wait. Read-only measuring is fine meanwhile. Worktree objectstack-issue-27216 on that branch from a fresh origin/main (git checkout --detach the main checkout first, then git worktree add --no-track -B <branch> ../objectstack-issue-27216 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=27216 --file=F --json run ONCE with output captured to a file (no time-shaped stamp inside the fenced report JSON). ⛔ 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 #27216, 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 (merge origin/main first if it refuses as STALE TREE); node scripts/check-sdui-manifest.mjs is a gate on every ui card. Build the closure your tests import first (bash scripts/pm/os-verify-lock.sh -c "pnpm --workspace-concurrency=2 --filter '<pkg>^...' build"). Changeset in the root .changeset/ for each published package your diff changes (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 one message (PR, head sha, report gist); keep the thread open through review and drive CI to green. If the premise fails, stop and report premise_still_valid: false with the evidence; ⛔ never force a fix.

   Ruling (cannot be re-ruled)

   Main-red convention ①, triage 27216 body: p0 anchor. ⛔ Never skip, retry-wrap or quarantine the test, and never loosen the assertion to toContain. The product rule (only the apps /me/apps lists) stays exactly as strict. The test owns the data it asserts on (maintainer 「同意，搭在 #27116 上做」).

   PM mechanism assumptions (measure; disproof welcome)

   On origin/main (read-only, file ui/packages/app-shell/src/hooks/__tests__/useLauncherApps-26838.test.tsx, from PR #27021):

   • The red line is L100, expect(entries).toEqual([SETUP, CRM]), in the first case. entries is seen.mock.lastCall?.[0], recorded by a useEffect in Entries. The await waitFor just above waits on the DOM text of Probe (/^setup,crm$/), not on seen.
   • While the /me/apps read is pending the hook narrows nothing, and hidden drops account (see the "outside a provider" case: setup,crm,showcase_app). So the pre-answer apps is exactly [SETUP, CRM, SHOWCASE], three entries with Showcase, which is the red's shape.
   • Seat's reading: a race inside this test, not a cross-test leak. waitFor can resolve between the commit that paints setup,crm and the passive-effect flush that records it in seen, so lastCall is still the pending render's array. The triage body's "state shared across tests" guess is the alternative, and your measurement decides between them. Under the shard-load reds (Test UI 3/16 and 4/16), slower effect flushing makes the window wider.

   PM suggested route (optional; measurement wins)

   1. Reproduce first. Run the file repeatedly under load (for example --repeat or a loop with --maxWorkers constrained, or vi.useFakeTimers off), and record the red count before the fix.
   2. Fix in the test, for example by asserting on seen inside the waitFor (await waitFor(() => expect(seen.mock.lastCall?.[0]).toEqual([SETUP, CRM]))), keeping the identity toBe(SETUP) and the single fetch. Check the other cases in the file for the same DOM-then-effect read, and the sibling CommandPalette.launcherHiddenApps-26838.test.tsx.
   3. If the measurement shows a real leak instead (a module-level store in useLauncherApps.tsx surviving across tests), reset it in the test's afterEach, and say which test seeds it.

   Proof: the same repeat loop is green after the fix (record N runs, 0 red). Ablation: restore L99–100 as they were and the loop reds again.

   Scope

   File surface: ui/packages/app-shell/src/hooks/__tests__/useLauncherApps-26838.test.tsx, plus ui/packages/app-shell/src/chrome/CommandPalette.launcherHiddenApps-26838.test.tsx only if it carries the same race. ⛔ No product-source edit unless measurement proves a product defect; if it does, stop and report first. No changeset (tests only; app-shell is private).

   Serial: no open PR touches these files (open PR list read 2026-10-28T10:58Z).
