The fact he references the Conduit, a backdoor to the Citadel created post-extinction, but doesn't even hint at the fact Protheans were building a superweapon during the war itself, or even suggest looking for any data on it. They weren't anihilated instantly - Liara even mentions it took the Reapers centuries to wipe out the galactic-spanning empire, so surely some information on that would be on Ilos before it went dark - the same way it was in the Mars archives, and those being a small data cache compared to Ilos facilities.

Also while I'm at the very selective Prothean memory - remember how Javik says he doesn't know squat about the Catalyst, never saw the Citadel, etc, because he was born in the final years of extinction? Yet he perfectly recalls all the Prothean meddling with the Asari, even though those events blatantly preceeded the Prothean war with the Reapers.
