Summary by CodeRabbit

• New Features

  • Improved sign-out synchronization across app windows, including automatic Settings window closure.
  • Added reliable magic-link authentication handling across the app and Settings.
  • Added cleanup for leftover authentication data and protection against stale sessions restoring after sign-out.
  • Redesigned the login screen backdrop with an animated letter-glitch visual, reduced-motion support, and accent colors.

• Bug Fixes

  • Local identity data is no longer incorrectly treated as an active session.
  • Sign-out now immediately clears authentication state and related stored tokens.

📝 Walkthrough

Walkthrough

The change makes sessions depend on JWT-backed tokens, synchronizes sign-out across windows, clears leftover renderer tokens, prevents stale session restoration, and replaces the login tunnel backdrop with an accent-based letter-glitch animation.

Changes

Authentication session lifecycle

Layer / File(s)	Summary
Token-based session resolution apps/desktop/src/main/services/session.ts, apps/desktop/src/main/handlers/authSyncHandlers.ts, apps/desktop/src/main/services/__tests__/session.test.ts	resolveSession no longer uses local identity fallback. Tests now require a token-backed session.
Renderer sign-out state and token cleanup apps/desktop/src/renderer/stores/authTokenKeys.ts, apps/desktop/src/renderer/stores/authStore.ts, apps/desktop/src/renderer/stores/__tests__/*	Sign-out clears auth storage, resets state immediately, and blocks stale asynchronous operations from restoring authentication.
Cross-window sign-out and magic-link events apps/desktop/src/main/windows/*, apps/desktop/src/main/index.ts, apps/desktop/src/main/handlers/authSyncHandlers.ts, apps/desktop/src/renderer/hooks/*, apps/desktop/src/renderer/App.tsx, apps/desktop/src/renderer/pages/settings/*	The main process broadcasts auth:signed-out, closes the settings window, and the main and settings renderers consume authentication events. Deep-link token handling moves to useAuthSessionEvents. Tests cover the sign-out wiring.

Login backdrop animation

Layer / File(s)	Summary
Letter-glitch rendering engine apps/desktop/src/renderer/components/auth/letterGlitch.ts	Adds accent color parsing, grid generation, glyph painting, letter mutation, smooth color transitions, and reduced-motion loop control.
Backdrop integration and validation apps/desktop/src/renderer/components/auth/LoginBackdrop.tsx, apps/desktop/src/renderer/components/auth/LoginBackdrop.module.css, apps/desktop/src/renderer/components/auth/__tests__/loginBackdrop.test.ts	LoginBackdrop uses the new grid, handles accent changes and debounced resizing, and keeps the veil non-interactive. Tests cover rendering and animation behavior.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🟠 High · up to 3daed

This release changes desktop authentication and sign-out behavior, but the current code can accept expired sessions during some failures, restore authentication after a concurrent sign-out, or leave other open windows signed in when cleanup fails. These are high-impact correctness and security risks that should be resolved or explicitly accepted before merging.

Prevent stale authentication work from restarting auto-sync.

Both methods check sessionEpoch before they authenticate. They then await startCloudSyncIfReady().

If sign-out occurs while startCloudSyncIfReady() waits for license and encryption state, logout() stops auto-sync first. The pending helper can then call startAutoSync() after sign-out completes.

Pass the captured epoch into startCloudSyncIfReady(). Check it again immediately before startAutoSync().

Proposed fix

-        await startCloudSyncIfReady();
+        await startCloudSyncIfReady(epoch);

-export async function startCloudSyncIfReady(): Promise<void> {
+export async function startCloudSyncIfReady(expectedEpoch = sessionEpoch): Promise<void> {
   try {
     const [licenseState, encryption] = await Promise.all([

     ]);

Propagate sign-out after cleanup attempts.

In auth:logout, storage.clearTokens() runs before localIdentity.clear(). If either cleanup rejects, the handler returns { success: false, error } before broadcastToWindows('auth:signed-out') and closeSettingsWindow?.(). Other renderer windows can retain authenticated state, and the settings window can remain open. Run both cleanup operations independently, then propagate sign-out and return the cleanup error. Add tests for both rejection paths.

Reject expired tokens before restoring an offline session.

When getCurrentUser() throws any non-401 error, resolveSession() accepts a JWT with valid sub and email without checking exp. TokenStorage.hasTokens() checks only file existence. Restrict fallback to transient API failures, reject expired tokens, and add a test for an expired JWT with a non-401 error.

Repaint the frozen backdrop after an accent change.

When reduceMotion is true, the loop schedules no frames. This observer only replaces grid.colors, so every visible letter keeps its old color until the component remounts. Recreate the grid or update each letter color and call paint() in the reduced-motion branch.

Proposed fix

     const observer = new MutationObserver(() => {
-      grid.colors = readGlitchColors();
+      const colors = readGlitchColors();
+      if (reduceMotion) {
+        grid = createLetterGrid(
+          Math.max(1, canvas.clientWidth),
+          Math.max(1, canvas.clientHeight),
+          colors

Exercise the logout flow instead of checking source text.

These tests read TSX and handler files as strings. They can pass even when handleSignOut is not connected to the button, IPC listeners are not registered, or auth:signed-out does not update runtime state.

Use mocked IPC and mounted components to assert the actual logout request, sign-out event handling, token cleanup, and settings-window closure.

Serialize concurrent session mutations.

Only applySignedOut() increments sessionEpoch. continueLocally(), verifyToken(), and loadSession() can therefore commit concurrently.

On cold start, loadSession() can return null after verifyToken() succeeds. Lines 215-220 then overwrite the verified user and return the user to AuthGate. The new useAuthSessionEvents listener makes this race reachable while startup session loading is pending.

Increment a session-operation generation when each operation starts. Allow only the latest operation to commit state.

Proposed fix

-const epoch = sessionEpoch;
+const epoch = ++sessionEpoch;

Apply this to continueLocally, verifyToken, and loadSession.
