How does a host CPID propagate through the projects?

Yes, I saw this. And it explains how an account CPID is propagated. However, how is a Host ID propagated? I dont see where a timestamp for the Host CPID is stored or used.

There is no host (computer) CPID as such. Host ID are assigned by and are unique to a project. The CPID is used to safely interlink accounts and hosts for stats purpose.

Boinc V 7.4.36
Win7 i5 3.33G 4GB NVidia 470

I believe this is wrong. Please see <host_cpid> in the <user>
section of a reply to "project/show_user.php" on
http://boinc.berkeley.edu/trac/wiki/WebRpc

Host CPID is stored in client_state.xml and is included in the sched_request_projectname.xml on contact to each project server.

Also, Jord linked to the correct page for you. It is under the section "Cross-project identification of hosts".

thats all good and well, but can you guys PLEASE do something about boinc changing this ID randomly on reboots, never had this problem until somewhere in the 6.10.xx era(can't remember exactly when it changed) and now it not only changes host cpid but then also generates a new boincstats BAM host id as well(I know that isn't really your area).

I long for the good old days.
