I recently had some siding installed. This involved cutting into the wall's rigid foam weather barrier in order to install blocking between studs.

When they replaced the removed portions of foam weather barrier, they did not tape some of the seams from the cuts. I am concerned in particular about the long seam which is positioned directly behind the butt joint where the trim meets the siding, which I'm guessing will be especially vulnerable to water intrusion.

They also installed housewrap over the foam boards. They did a pretty good job of running it right up to the trim, but they also did not tape it along the edges.

I wish I had noticed this before they put the siding on. How bad does this look? Is it likely to lead to serious water damage? If so, is there anything I can do about it without tearing off siding?

Your first two questions are subjective and speculative. My subjective opinion is that there wasn't a practical alternative approach without removing the frieze board and running new membrane behind it. I'm not sure why that wasn't done, but there could be good reasons. My speculation is that because of its location, unless your region is prone to downpours with gale winds, it's unlikely to see enough water to get past a good caulk joint.

I suppose they could've slipped a Z-flashing behind the bottom of the frieze board, but that seems unnecessary. It would also look unappealing.

All you can (or should) do now is ensure that the caulk is done well. I really don't think it's much of a concern up there.
