After the heist starts we receive: "The (else:) changer should be stored in a variable or attached to a hook", then when we enter the house we receive: "I need useable code to be right of '='", "There's no (if:) or something else before this to do (else-if:) with", and "There's nothing before this to do (else:) with".
Also, you say there's no way to win but:
"You crack the lock without much issue, but the door swings on by with an awfully loud creaking sound, causing the master of the house to begin to stir..."
followed by a black screen after resisting that consequence (going to 7/10 stress, 0/4 alert) sounds like winning to me.
