TSA training requirements for CFIs

I've looked at government documents about the TSA recurrent
CFI training until my head hurts. Can anyone summarize what
I need as an independent CFI to show that I've followed
whatever rules there are?

I've taken an online quiz where every other answer is to ask
my non-existent supervisor. I printed out a form that said I
finished the TSA course. I read the
"recurrent_flight_school_module.pdf" document, which seems
to say I've done recurrent training by looking up stuff
about my airport. It seems to have a form that I sign
myself certifying that I've trained myself and a logbook
entry that I make to myself to verify what I just certified
to myself. Can that be right?

What records about my students do I need to keep for the
TSA? I know what the FAA wants.

Is there a good link that explains this that I couldn't
find? Help is gratefully appreciated from anyone who has
figured this out.
