Equity Split and Title Advice - i will not promote

Hello all! I'm new to the startup world and would appreciate some advice on what a fair equity split and founder structure looks like. I’ll begin with a timeline: August 2025: Professor suggests idea that would solve a problem she personally faces along with others in her industry. Patrick (computer science) and I (mechanical engineering) start working on it when the semester begins, with him doing it for a capstone project and me for experience and the small possibility of turning it into a startup.
