📝 Walkthrough

Walkthrough

Electron storage configures token files with mode 0600 and attempts to apply that mode to the store path. Tests cover the configured mode and verify that an ENOENT error from chmodSync does not cause storage() to throw. A patch changeset describes the permission change and its update timing for existing files.

Priority: ⬇️ Low

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🟡 Moderate · up to 55c60

An existing token file may remain accessible to other local users after storage initializes. Handle permission failures before merging the owner-only access change.
