JustinGamer191/Holo ? reverse-engineered prompt

Build me a native macOS app for MacBooks that lets me tap the desk around the laptop and use those taps like four customizable hot zones, left front, right front, left rear, and right rear.

I want it to listen through the built in microphone, walk me through a clear calibration flow with about 10 taps per zone, save desk profiles, and only run actions when it is confident enough about which zone was tapped. If the tap is weak, noisy, ambiguous, or seems like normal room sound, it should reject it instead of guessing. Please keep everything local and sandboxed, and do not keep raw audio unless I explicitly turn on debug recording.

Give me actions I can assign per zone like visual feedback, play a sound, copy or speak text, open a website, run a Shortcut, open an app or file, run a shell command, or take a screenshot.

I also want an evaluation mode that does a held out accuracy test and shows per zone results, latency, rejections, and a confusion matrix. Use current Apple docs if you need to.
