Improve Desktop App

Goal

Fix the selected desktop app boundary across UI/native layers, IPC, local storage/files, backend integration, tests, and packaging/release config when directly affected.

Scope selection

Use the selected desktop feature, OS integration, local data issue, auto-update problem, audit finding, failing test, or packaging failure. Do not rewrite the app shell or update system unless required by the selected fix.

Change targets

• Renderer/main/native process boundaries, IPC payload validation, OS permission requests, notifications, tray/menu/deep-link behavior.
• Local storage, secrets, file access, cache, logs, crash reports, offline/sync, migrations, and cleanup.
• Backend API integration, auth/session refresh, tests/manual scripts, packaging/signing/notarization config, docs/maps directly affected.

Implementation principles

• Validate all cross-process and external inputs.
• Protect tokens/secrets and avoid logging sensitive local data.
• Preserve platform compatibility and existing update/migration paths.
• Keep release and rollback gates explicit.

Validation

Run repository-native tests/builds and bounded manual/platform scenarios for the selected behavior, including offline/restart/update/permission states when relevant. Report unavailable signing/store/platform gates honestly.

Repair the owning IPC, native permission, local migration or lifecycle code and synchronize direct renderer/backend consumers. Replay the same operation and its denied control against synthetic files/state, then verify the affected restart/update path retains the correct identity and data. Feed this built/runtime evidence to the local-client check; fix remaining boundary failures before Patch Checking. Do not replace a missing platform test with a claim based on the development UI alone.
