(Aside: Does anyone have a link to a diagram of the dance the master and agent do? I've been meaning to try to make one on websequencediagrams.com but not gotten around to it.)

There is a diagram and accompanying descriptive text that looks pretty comprehensive here: https://docs.puppetlabs.com/puppet/3/reference/subsystem_agent_master_comm.html.

And one for the agent/master communication which I haven't found a good place for on ask: https://dl.dropboxusercontent.com/u/18472980/puppet-agent-timeseq.png 

Those all look good for what they are intended, but I was thinking more about something that was simplified for newish users and included where the various Ruby extensions are used.

I considered including the agent->master communication about File resources using "source" but couldn't quite find a satisfactory way to represent it.

I realize now that I am unclear about whether the master submits the compiled catalog and facts to PuppetDB at the time that the report is submitted or earlier; its probably not a detail worth worrying about though.
