AI Overlay for Proctortrack on Mac

Proctortrack is Verificient's proctoring product, used heavily in US higher education. It runs as a Chrome or Firefox extension paired with a "Proctortrack Setup" macOS app that performs the initial system check and biometric capture.

Proctortrack's setup app verifies your identity, captures a baseline of your environment, then closes; the actual exam runs through the browser extension. The extension uses Chrome's screen-capture API, which Apple wires to ScreenCaptureKit on Mac. Any window the OS has marked with the privacy flag is missing from frames returned to the extension. The behavior-analysis layer (eye tracking, audio for second voices, multiple-face detection) all reads from the webcam and microphone, never from the screen, so the overlay does not perturb those signals.

The setup app may enumerate running processes. Fracture uses a per-build randomized name (e.g. SystemDiagnostics, AudioConfig) so it does not appear as "Fracture" in the process list.

Proctortrack records ambient audio and runs voice-activity detection. The overlay makes no sound, so the audio signal is unchanged.

Proctortrack tries to detect VMs and will block the exam if it succeeds. Fracture does not require a VM and runs on bare-metal macOS.
