Whether his plan should work is another question of course!
You are leaping to conclusions in the absence of evidence.
First, we don't know what the return of the Archangels means. It does not necessarily mean that the "returned Archangels" will be in a position to actually change things if the plan is going awry. For instance, if it is just a hologram recording, it won't be able to physically do anything (though it might change mental attitudes). For that matter, we don't even know that the return of the Archangels was intended to bolster Langhorne's plan--there have been suggestions on this forum that it was a backstop plan by doubters.
Second, we only know that the Archangels will return after 1000 years. What about in 2000? 3000? Will the Archangels be returning for the next 10,000 years? Eventually, innovation is certain to rise; Safehold will either reach space or die in one disaster or another.
Third, we don't know that the KEW is actually active. Merlin is acting on the assumption that it is active and under orders to act independently, but he (and we) does not know that for certain. We don't know what orders it has, if any.
Fourth, even if it is active and would strike down any detected high-technology, we don't know what its limits are. Will it survive another 1000 years? 10,000? Has it already broken down? Are there circumstances where technology could arise that it doesn't detect in time?
Fifth, you are assuming that the KEW can stop incipient technological revolutions before it gets out of control. What if innovation and technology spread so far and so fast that the KEW cannot stop it without destroying large portions of the population? Will it do that? The extinction of Safehold is just as much a failure of Langhorne's plan to save the human race as the rise of a space-going technology would be.
The return of the Archangels and the KEW are not the guarantees of the perpetual success of Langhorne's plan that you think they are.
The Rankora (KEW) system was active enough to destroy any probe/drone Merlin tried to send out to it to check up on it. So the defense aspect of the orbiting KEW is working. With that, there's good reason to assume that the rest of it is working too even though it hasn't been used in hundreds of years. Until Merlin sent out the probes, the defense part hadn't probably ever been used either except for shooting the occasional asteroid/meteorite. If the maintenance systems can keep that running, there's nothing to assume that they couldn't keep the bombardment part of it in functional order either.
What Merlin and the circle know is that there's something under the Temple and that something will be 'waking' to check on the world in a few decades/hundreds of years. It could be several PICAs or 'Archangels' in hibernation. The last one is the more likely option imo since the only PICA that was sent with the colony we knew of was the one that became Merlin. Unless Langhorne had a bunch listed and shipped in as something else, the odds of it being another PICA is kind of low I think. It's far more likely some of the surviving 'Archangels' set up several hibernation units for them so they could check up on their descendants, and play God without anyone else around.
