I don’t see it, whether enemies can see you or not is situational. All the rules you need to decide that are there (even if they could be better), everything else is about the scenario you find yourself in or how strict / lenient the DM is, nothing in the DMG will help you there eitherIt's critically important for me as a player to know those two things before I pick a rogue to make a stealthy character.
