What, if any, forensics have been done so far?

For example has anyone tried fault insertion testing on a ground mock-up to
see if what failures can be induced that mimic as closely as possible what was
observed on the ISS? Do we know at the time of failure things like pump motor
current draw? Component temperatures? Was there any flow of coolant at all?
Are we talking frozen pump? Bad electrical connections? Leaky lines?

Is Google my friend or maybe this is being kept current on a blog somewhere
that I'm missing? Links always appreciated.
