So you've said. However,
1) If you had, anything interesting you could say would be classified,
   you'd have a clearance, and you'd go to jail for mentioning it.

"control program" is, but Matt's work certainly has nothing to do with
any such thing...

Ahem. What the hell are you talking about? Tessera has no concept of
"crypto synchronization" or the detection thereof.
