 Within the conesus header it had the lines you wanted...

 shared-rand-current-value 9 vLbCqI2m02UXzOUYtSMPWxC/QUSXSw0mrOBNyBCGtcE=
 }}}

 d713b29]). :P

 One bug I *am* spotting is that the 'reveal_count' attributes are
 undocumented. Also, if you fetch those *before* the 'current_value' then
 you get None. This is because when lazily loading stem is missing the
 'reveal_count' handler. Fixing...
