Did you find out what I did wrong and why it didn't work?  Was the missing

  str = origin(str);

the only thing?

Two things here:
 - I think that maybe 4 bits for the cost is too much.  We don't need 16
   levels.  2 bits should be enough.
 - If you add 4 bits for cost, you should reduce the RESERVED part with
   the same amount.
