Project description:
"I need a solid Windows desktop application, written in Python, that lets me queue and automatically send WhatsApp Web messages combining text and file attachments. A modern PySide6 interface should make it easy to create, edit and cancel tasks, while everything under the hood is handled by Windows Task Scheduler for absolute timing accuracy—even if the GUI is closed.

Core workflow
• The GUI stores each job in a local SQLite database and, on save, transparently registers it in Task Scheduler.
• When a task fires, an Undetected ChromeDriver instance loads WhatsApp Web with a persistent Chrome profile, runs in a “fake-headless” state (all visuals suppressed but still full-browser), and delivers the message + files.
• Multiple CSS/XPath fall-backs must be included so a minor WhatsApp update does not break the flow.
• Every run writes a detailed log (success, retries, selector used, timestamp) to disk for audit purposes.

Reliability matters more to me than raw speed, so please focus on graceful error handling, automatic retries, and clear logging. I also want a single-click installer or portable build—PyInstaller or similar is fine—plus concise setup notes covering required Python version, Chrome version alignment, and first-time QR login.

Deliverables
1. Full source code with clean structure and comments.
2. Packaged Windows build ready to run.
3. README / quick-start guide.
4. Short video or screenshots demonstrating a scheduled combined message (text + file) being sent in the background.
5. Optional: unit tests for the core automation functions.

I already have sample message templates and test numbers; once we agree on the architecture you can use those for validation. If something above is unclear, flag it early so we can lock the scope before you dive into coding." (client-provided description)
