: Something else ... we know that Garrick's party wasn't

Indeed, Dwarves have an affinity for magical devices; they knew just what to do with the Tain keys too.

We don't actually know that it was the Deceiver who figured them out, and not the Watcher. In Force 10 From Stoneheim, the Dark forces could have been coming through the Knot from anywhere. And they were exclusively mindless undead, which suggests that the Watcher rather than the Deceiver was commanding them.
I think the Dark just wasn't that *interested* in figuring them out. Sending small teams across the country into enemy territory is the Light's job; most Dark units aren't competent to fight except en masse, and World Knots don't transport them fast enough. A single Dwarf stationed at the exit knot could destroy an entire army of incoming Thrall.
Eventually they happened to work it out and sent, almost casually, a small force through to see what would happen. You stopped them, the Dark tabled that method of attack, and the war went on.
