Film fogging during darkroom processing destroys hours of photography work with no clear prevention method

Black and white film photographers experience unexpected fogging that ruins entire rolls of film during the critical window between stop bath and fixing stages, destroying hours of shooting and darkroom work. Photographers lack clear, reliable guidance on preventing this specific fogging issue, forcing them to waste expensive film and chemicals while troubleshooting through trial and error. Current darkroom practices and documentation don't adequately address this particular failure mode.
