Team switching waited for the Stack Auth selection write before changing the dashboard scope, so a slow response made clicks appear ineffective for several seconds.

The switch now updates the shared catalog, legacy cookie, and ?team= request scope immediately, then reconciles with Stack Auth. Failed writes roll back the catalog, cookie, and URL. The menu also consumes rejected switch promises after rollback.

Validation:

  • bun test tests/dashboard-team-scope.test.tsx
  • bun test tests/dashboard-account-menu.test.tsx
  • bun run lint -- 'app/[locale]/dashboard/dashboard-team-scope.ts' 'app/[locale]/dashboard/dashboard-account-menu.tsx' 'tests/dashboard-team-scope.test.tsx'

Summary by cubic

The current description already accounts for the merge and the latest commits. The only new work since the baseline is a type-level fix in the test helper and a merge from main, so no behavior changed. Here the description remains accurate as-is.

Team switching now updates the dashboard scope immediately instead of waiting for the Stack Auth selection write, so slow responses no longer make clicks appear ineffective.

  • Updates the shared catalog, legacy cookie, and ?team= URL scope before the server responds, then reconciles with Stack Auth.
  • Snapshots the previous state so a failed write rolls back the catalog, cookie, and URL, and the account menu consumes the rejected promise so the error stays silent.
  • Tags each switch with an operation id and serializes persistence so a stale failure cannot roll back a newer switch.

Written for commit e52afbe. Summary will update on new commits.

Summary by CodeRabbit

  • New Features

    • Team switching updates the dashboard and team URL immediately while the change is saved.
    • Team-specific links stay synchronized during switching, and the temporary team parameter is removed after a successful change.
    • The dashboard refreshes after the latest team switch succeeds.
  • Bug Fixes

    • Failed or timed-out team changes restore the previous dashboard state, URL, and team scope.
    • Overlapping switches no longer let an older failure undo a newer selection.
    • Asynchronous team-selection actions are handled safely without unhandled errors.

📝 Walkthrough

Walkthrough

The dashboard team switch now supports asynchronous selection callbacks, optimistic cache, cookie-scope, and URL updates, rollback after failure, and coordination between concurrent switches. Tests cover successful switches, failures, and newer-switch precedence.

Changes

Dashboard team switching

Layer / File(s) Summary
Async team-selection callback
web/app/[locale]/dashboard/dashboard-account-menu.tsx
TeamSubmenu accepts void or Promise<void> callbacks. The radio-group handler catches returned promise rejections.
Optimistic switch and rollback
web/app/[locale]/dashboard/dashboard-team-scope.ts
switchTeam updates the catalog, legacy cookie scope, and URL before persistence. It restores prior state after failure and avoids overwriting a newer switch. Successful active switches remove the query parameter and refresh.
Switch flow tests
web/tests/dashboard-team-scope.test.tsx
Stateful cache, router, and cookie-scope mocks verify optimistic updates, successful cleanup, concurrent switches, and rollback.

Merge Risk: 🔵 Low · up to e52af

Team switching now updates the dashboard immediately and recovers correctly from failed or overlapping switches. One narrow issue remains: if the user moves to another dashboard page or changes filters while a switch is still saving, completing the switch can send them back to the earlier location. This is a small, fixable follow-up rather than a data or security risk.

Full details: Description check

Explanation

The description includes a clear summary and validation commands, but it omits the required Demo Video section and repository checklist. The change affects UI behavior, so the missing demo video is significant.

Full details: Cmux Cache Substitution Correctness

Explanation

The PR introduces a React Query cache read as the catalog source for the rollback snapshot: queryClient.getQueryData(queryKey) ?? data. The authoritative catalog comes from GET /api/subrouter/teams, which resolves the selected team from Stack Auth. The rollback path later restores this snapshot with setQueryData, so it is an undo consumer that can trust an older catalog. The fallback covers a cold query cache, but the code does not check dataUpdatedAt, await a fresh GET, or otherwise prevent a stale cache from being captured. staleTime: 0 only marks the query stale; it does not force a fresh read before switchTeam. No call-site rationale documents why stale catalog data is harmless.

Resolution

Before creating confirmedSwitchState, obtain a fresh catalog from /api/subrouter/teams (for example with a freshness-enforced queryClient.fetchQuery or a direct GET), or use query freshness metadata and fall back to that read when the cache is stale. Keep the existing cache fallback only for the never-loaded case. Alternatively, after a failed persistence, re-read the authoritative catalog before restoring the query cache instead of restoring the cached snapshot. Preserve the cookie and URL snapshot logic separately, and add tests for an older query-cache value and for a refetch that updates the server before rollback.

`renderReadyScope` assigns `probedScope = undefined` and then renders the
Probe, which reassigns it from inside a closure. Control flow analysis cannot
see that write, so it held the variable at `undefined` for the rest of the
function and `!scope` narrowed the union away entirely — every `scope.switchTeam`
in the suite failed `web-typecheck` with "does not exist on type 'never'".

Read the probe through a function so the declared type survives, and give
`renderReadyScope` an explicit ready-variant return type so the call sites do
not depend on inference through the same reset.

Types only; the 12 tests in this file passed before and after.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

A completed switch replaces the URL with a stale location.

switchTeam captures pathname and searchParams when the switch starts. Each switch now ends with router.replace(pathWithSearch(pathname, ...confirmed.search)), on both success and rollback. confirmed.search is also a snapshot from the first queued switch.

Suppose the user moves to another dashboard page or changes other query parameters while a PATCH is pending. The PATCH can take up to CATALOG_TIMEOUT_MS, and queued switches take longer. When the PATCH completes, the replace sends the user back to the old path and drops the newer query parameters.

The old code did not have this problem in the common case. It replaced the URL only when ?team= was already present. The optimistic ?team= write makes this replace run on every switch.

Before the replace:

  • Read the current location from a ref that is updated after each render.
  • Skip the replace if the current pathname differs from the pathname captured at switch start.
  • Otherwise, change only the team parameter of the current search: delete it on success, or restore the rolled-back value on failure.
🐛 Proposed approach
const latestLocation = useRef({ pathname, search: searchParams.toString() });
useEffect(() => {
  latestLocation.current = { pathname, search: searchParams.toString() };
});
-      router.replace(
-        pathWithSearch(pathname, new URLSearchParams(confirmed.search)),
-      );
+      if (latestLocation.current.pathname === pathname) {
+        const next = new URLSearchParams(latestLocation.current.search);
+        next.delete("team");
+        router.replace(pathWithSearch(pathname, next));
+      }

Apply the same pathname guard to the rollback replace. In that branch, restore the team value from rollback.search onto the current search.
