DEADMAN610716/wpair-app ? reverse-engineered prompt

Build me an Android app called WPair that helps security researchers check whether nearby Bluetooth audio devices are vulnerable to the Fast Pair issue described in the README.

I want a clean scanner screen that finds nearby Fast Pair devices, shows their status, and lets me run a non invasive vulnerability test on a selected device. If a device looks vulnerable, the app should clearly explain that, and offer a proof of concept flow for authorized testing only. After pairing, add a simple audio screen that can connect over hands free audio, play the live microphone stream through the phone speaker, and record it to an M4A file. Also include a recordings view so I can see saved clips.

Make the UI feel polished and easy to use, with the logo and screenshots style from the repo. Use the current Android and Kotlin docs online if you need to. Keep the app focused on Bluetooth scanning, testing, pairing, and audio handling, and make sure permissions and error states are handled nicely.
