Wild day, enjoyed by all I'm sure.

Precision seems to be everything in these discussions.

Since SGX obviously does not mitigate micro-architectural state
probing it is not an effective general remediation against MELTDOWN.
Does your statement indicate there is solid documentation that
MELTDOWN can be used by a process of any privilege level to dump out
the unencrypted contents of an initialized enclave?

That would obviously be a big story as well.
