The agent appears to be posting it. What happens to it? Does it get compared to previous catalogs?

The client requests the catalog using a POST request; the actual catalog is sent from the master to the client in response to the POST. If I recall correctly, facts and other metadata are sent as part of this request, but I may be mistaken; it's been a long time since I did log or traffic analysis on the Puppet communication channel.

The client doesn't ever send the catalog back to the master. It does however submit it's facts and run report (assuming reporting is enabled.)

A client requests a catalog using POST? I see. I didn't expect that. Thanks a lot. Does the server behave differently when storeconfigs is enabled when the client submits the facts and report?

Storeconfigs happen on the back-end. It doesn't really have an impact on the client/server communication. Fact collection, reporting, etc will happen even if storeconfigs isn't enabled.
