I don't believe it is. As I understand it, what you're saying is that the Traveler was actively searching for someone "special" and then consciously caused the "accident" to happen when he found Wesley.
I'm not
exactly saying that. That
is something of a leap. I initially said I like the idea, & drew some hypotheses around it, but it's entirely possible to not be the case too. What I do think is that he is self-defined as a lone traveler, who chooses to seek out & interact with others he finds, & what would be the point of that except to connect in some way with other's like himself, others like Wesley, with whom he has this commonality of special connection to the universe?
Also he's maybe examining creatures he finds who aren't quite yet there, but are on the path to it, like Humans, & kind of even helping them along a little bit in lesser ways, like their propulsion techniques etc.... So was he on a mission to find someone like Wes? Probably not. Was he generally looking for others who he is like? Very possibly, & did he find Wes to be one of them? I think so. Now as to the deliberateness of the event...
According to the script, the "Assistant" (aka the Traveler) was sharing his propulsion insights (while letting Kosinski take the credit) in exchange for just getting to wander and explore. When he happened across Wesley by chance, he noticed that the boy was a genius and encouraged him to tweak the warp equation, which had the unintended effect of making the improvements work even better than expected. You're reading premeditation and deceit into it, and I don't believe that was the scripted intent at all
It's not premeditation, & certainly not deceit I'm implying, but if the Traveler understands these permutations or whatever, then anything Wes would've done to them, he'd be more than likely to understand the consequences of. Whatever Wes did, if it had the effect of causing that event, then he certainly had foreknowledge that something like this would or could happen. I mean this is his natural state, doing things like this, & Wes is in the infancy of it.
What I think is there's reason to believe that when he saw Wes do it, at that point, he kind of knew they were in for a ride, & decided to let it play out. Maybe he didn't expect it to get as out of hand as it did, but it certainly isn't out of the realm of possibility that he'd known what was coming. Was that his mission statement, to go find people burgeoning on manipulation of the space/time continuum, & then give them a push? I highly doubt it.
He's just a traveler, out there looking to understand the people out there (Not unlike our crew) & he probably has gone a looooong time without encountering anyone like himself. So when Wes came along he let it happen because it
is something special, & maybe ought to be brought out. That's not really premeditation, but it certainly isn't all accident either. It's letting the chips fall where they may. The only accidental thing about it imho, is that it went a little too far, & Mr. Traveler had an unintended difficulty in returning this city sized vessel of panicked people back to where they started.
