What common mistake do developers make with Rules method, why does the mistake cause problems, and what is the safer approach? One recurring problem with rules method is applying it without understanding the boundary it protects. Returning true from authorize for every protected operation when authorization should depend on the current user and resource. In addition, The rules method defines the validation constraints for incoming fields. Safer engineering approach: keep the responsibility in the correct layer, use the framework's supported API, validate and authorize inputs, avoid hidden side effects, and verify the behavior with tests.
