Description

Keep the latest client token available when Electron cannot persist it securely, allowing the current authentication flow to continue without writing plaintext tokens to disk.

Successful writes continue using persisted storage as the source of truth. The in-memory fallback is removed when persistence recovers or the token is cleared.

Fixes the same issue as #9584 but handles it in the main process to avoid multiple renderer window collisions & IPC races

📝 Walkthrough

Walkthrough

The Electron storage adapter retains client tokens in memory when persistence is unavailable or fails. Reads check memory before electron-store. Per-key mutation versions prevent stale asynchronous writes and re-encryption from replacing newer values. Tests cover delayed encryption, removal, persistence recovery, and failure handling. A patch changeset documents the behavior.

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

Merge Risk: ⚪ Minimal · up to 3f6f5

This localized Electron storage fix is merge-ready after normal checks and review; no actionable merge-blocking risk remains.

133-138: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win

Add explicit return types to the mutation helpers.

Declare beginMutation as : number and isCurrentMutation as : boolean.

Proposed fix
-  const beginMutation = (key: string) => {
+  const beginMutation = (key: string): number => {
     const version = (mutationVersions.get(key) ?? 0) + 1;
     mutationVersions.set(key, version);
     return version;
   };
-  const isCurrentMutation = (key: string, version: number) => (mutationVersions.get(key) ?? 0) === version;
+  const isCurrentMutation = (key: string, version: number): boolean =>
+    (mutationVersions.get(key) ?? 0) === version;

As per coding guidelines: “Always define explicit return types for functions, especially public APIs.”
