When the confirmed URL matches the current URL,
url.refresh()is the operation that refetches the active dashboard queries. If it rejects, this catch discards the failure. A route such as/dashboard/coderoutercan then continue rendering cached data for the previous server-selected team while the catalog, cookie, and URL represent the new team.RouteSectionErroronly provides recovery after a router error reaches the boundary, andTeamSubmenualso discards the rejectedonSelectpromise. Route refresh failures need a visible retry or reconciliation path instead of being swallowed. Do not roll back the already confirmed server switch.🤖 Prompt for AI Agents

- Around line 191-194: In the dashboard team-scope refresh flow, prevent stale
completions from changing the current error state: assign a monotonically
increasing sequence number to each team-switch refresh and retry, and update
refreshError only when the completing call still has the latest number. Add a
regression test that resolves overlapping refreshes in reverse order and
confirms the superseded result is ignored.

Test the generation guard through useDashboardTeamScope.
The current test calls only isCurrentRefreshGeneration. It does not exercise startRefresh, so incorrect generation arguments or missing guard logic would pass.
Add a hook-level test that starts two overlapping refreshes with deferred promises, rejects the newer refresh, then resolves the older refresh. Assert that refreshError remains true. Use promise completion signals instead of iteration-bounded waitFor.

Summary
Dashboard team switching updated the picker optimistically but awaited the full server-rendered dashboard refresh before resolving. A slow page dependency could leave the picker in a switching state for 10+ seconds.
The selection endpoint also reloaded the caller's complete, paginated team membership for every switch. That made the first cold switch especially slow, while later switches appeared faster after the auth/provider path warmed up.
After the server confirms the team selection, the switch now resolves immediately and the dashboard refresh runs in the background. Selection authorization now looks up only the requested team (and the current selected team when its details are needed), preserving membership checks without the full membership reload.
