I don’t need evidence to evaluate the known facts of this situation, such as UK law of succession. Obviously you would rather belief salacious gossip than use common sense to figure this out. The monarchy would be in danger collapse if they did not perserve bloodlines, because that is their primary claim to the throne. If Harry were not a biological son, some disgruntled hospital employee with a dirty mind who likes to stir the s*** would test his DNA against Charles’ and call the tabloids. Be logical.
Sounds like your resentment that Diana had affairs AFTER Charles resumed his ongoing affair with Camilla AFTER Harry was born has blinded you to common sense.
