Comprehensive Audit for AI Gym OS

I have a complete Gym OS that consists of a web app, a members-side mobile app, a staff-side mobile app and its public landing page. Every line of the codebase was generated with Claude AI and I need independent eyes on the whole stack before the product reaches paying gyms...
