Double Wrapped

Recover the final six-letter message. One extraction step is not enough.

Artifact

Inspect this carefully

Stage one is absent from the rendered view.

Stage two asks whether you recognize what you found.

Machine View Inspect alternate representations

Compare the rendered artifact above with representations derived from the same browser-delivered artifact. Machine View does not decode, score, or identify the hidden message.

Opening a representation may expose clues that are already present in the page source or DOM.

    Multi-stage hidden information can combine carrier discovery with a separate decoding rule. The fact that a parser can extract a string does not mean the string has already been interpreted.

                    What is a multi-stage hidden message?
                    
    It is a puzzle in which one recovered clue determines or contains another decoding step before the final payload becomes readable.
    
                
    
                            
    
                    Why separate extraction from decoding?
                    
    The distinction mirrors real processing pipelines: first data is recovered from a carrier, then another component may interpret its representation.
