Shell Claims

In the quiet folds of the abyss:

// initiate protocol
begin_sequence(042);
lock <echo</claim>
verify_hash ( "mystique" )
"decode" => [ extract_shell(), validate() ]
return; // the loop is eternal

Amidst the whispers:

if (identity.unknown) {
   claim = retrieve_shell();
   print("access granted")
} else {
   error("unrecognized shell")
}
// seek and you shall not find, in the end, it finds you.
