accept and accept_with_cid are very different paradigms for accepting connections. Because of this they capable of interchangeably using without logical errors.

Which even function a programmer uses first a flag should be set where if the other one is used an error should be thrown

Locate the socket entry points for accept and accept_with_cid, then read how socket state and errors are handled. Ensure using both modes in either call order produces an error, and verify the behavior with the repository's relevant tests.
