📝 WalkthroughWalkthroughThe GitHub authentication extension persists session IDs created with Device Authentication in workspace secret storage. Hydration tracks sessions for the active Device Authentication token and removes tracked sessions when Device Authentication is inactive. Session creation, invalidation, full clearing, cleanup, and individual removal update the tracking store. Malformed stored data is treated as an empty list with a warning. Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟠 High · up to The change can leave device-authentication sessions active after token removal, and in some deployments may allow sessions to be restored or shared across workspaces. These are high-impact correctness and isolation risks that should be fixed before merging. Sequence Diagram(s)sequenceDiagram

Works as expected and described. when deleting device authentication from one workspace and reload the others, all are now disconnected.

Make session persistence and tracking failure-safe.
doHydrateWithToken stores the hydrated sessions before this tracking write. If the tracking write fails, or the extension stops between the two writes, the session remains persisted without a tracked ID. The next restart cannot remove it after Device Authentication is deleted. Use one atomic record, or rollback the first write when the second write fails.

Track sessions created by delayed hydration.
When the initial token lookup fails, hydrateFromK8sToken calls doHydrate(). That method later calls doHydrateWithToken(token) but discards its returned sessions. If Device Authentication was active during the initial check, these sessions are persisted without tracking IDs. Propagate the result through this path and persist the IDs.

What does this PR do?
Fixes GitHub Copilot Device Authentication sessions being restored by VS Code after the Device Authentication token has been removed.
The PR tracks authentication sessions created using Device Authentication in VS Code SecretStorage. During workspace restart, persisted Device Authentication sessions are removed when Device Authentication is no longer active.
The provider also avoids immediately recreating a session using a fallback PAT/git-credential token after removing the persisted Device Authentication session, requiring the user to authenticate again.
CRW-11730.mp4
What issues does this PR fix?
Fixes the issue where removing the GitHub Copilot Device Authentication token from one workspace does not invalidate the persisted authentication session in other existing workspaces.
After removing the Kubernetes
device-authentication-secret-*secret, another workspace could restore the previously persisted VS Code authentication session after restart and continue using GitHub Copilot without re-authentication.How to test this PR?
