 > > Hm. I think CIRCUIT_PURPOSE_C_INTRODUCE_ACK_WAIT is the right purpose
 to start applying padding for the purposes of the prop302 machines ,
 because it's after receiving INTRODUCE_ACK is received that we should
 start  sending padding, and not after sending INTRODUCE1.

 > Wait, isn't C_INTRODUCING before ACK_WAIT? The original code listed
 C_INTRODUCING as well, which means we were firing up machines earlier,
 right?

 Hm. I don't think the original code listed `C_INTRODUCING`:
