The Shadow Broker intel network doesn't have any operatives in dark space, embedded in the Reaper fleet, as far as I'm aware. I never really understood how Liara having access to the intel network would do any good; at best, maybe she learns about some anti-Reaper superweapon, but she can't actively track the Reapers or eavesdrop on their plans.

And I don't think those are actual schematics of Harbinger in that datapad. Even if they were, knowing how a Reaper is structured isn't the same thing as being able to hurt it. If I have the schematics of a tank, I still need a weapon capable of taking it out.

I think you're underestimating the Reapers' capabilities. They've been around for millions of years, and they didn't succeed for that long by being stupid. It's obvious they had a contingency plan for the Citadel relay being closed to them, otherwise they wouldn't still be an imminent threat. And if the entire Reaper fleet can enter the galaxy, no way any defending force can withstand them. Where the galaxy has to worry about protecting habitation centers and supply lines and other infrastructure, all the Reapers have to do is reach the Citadel and shut down the mass relays. If the potentially thousands-strong Reaper fleet stays together, attacking them head-on would be suicide.
