Description

Fixes CORE-4131.

In the Mosaic UserProfile, if you opened Active Devices, closed it, and then signed out, your session list, including IP addresses, stayed in memory. The cleanup only ran while the section was on screen.

Now the section's data is cleared on sign-out whether the section is open or not. Nothing is cleared while Clerk is still loading. Only the Mosaic session list signs up for this cleanup, so nothing else in the cache is cleared on sign-out.

Nothing changes on screen. While signed in, closing and reopening Active Devices still reuses the cached list. The legacy UserProfile and billing's sign-out cleanup are unchanged.

Checklist

  • pnpm test runs as expected for the affected suites: all 1,370 shared tests, 2,959 legacy UI tests, 1,296 Clerk runtime tests, and 30 active-device browser tests pass.
  • pnpm build runs as expected. The shared and legacy UI production builds and affected typechecks pass; the full monorepo build was not run.
  • (If applicable) JSDoc comments have been added or updated for any package exports
  • (If applicable) Documentation has been updated

Walkthrough

The change adds persistent sign-out cleanup for registered authenticated query keys. When the Clerk user becomes null, matching queries are removed, including after the related section unmounts. The sessions query uses the new cleanup hook. Tests cover subscription lifecycle and cache behavior.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Severity of issue fixed: Low

Merge Risk: Low · previous review d6458

Apps using multiple Clerk instances can retain cached device data after sign-out. Address this before relying on cleanup in those apps.

Matches Sign-out after Active Devices closes clears cache

With the section unmounted, sign-out left the device query and both IPs in the cache before. After the change, the cache is empty.

Keep cleanup subscriptions for overlapping Clerk instances

If two roots use distinct Clerk instances, registering Active Devices in the second root unsubscribes the first instance. If the first instance then signs out after Active Devices unmounts, its authenticated session data can remain cached. Keep a cleanup subscription for each active Clerk instance.

Update registerQueryCleanupOnSignOut to track cleanup subscriptions and

sign-out from either Clerk removes its authenticated queries.
