Imagine something like this happening halfway to Mars and zero chance of escaping, getting any help or parts sent to you.

There is less debris around on the way to mars and this is a known and worsening for the ISS due to its age.

Seems like these structural integrity problems are always inside the Russian section. So if you're on a Russian mission to Mars, yes it would be reasonable to be worried. Otherwise this seems like a non-issue.

Recently started an embedded hardware/software job. Shipping firmware to the manufacturer feels like that for the device classes that have no internet.

Ah yes, the well traveled and highly tested human mission to Mars.

Maybe someone who knows more about the ISS than I do can answer this:

Naively, I would assume that there are airlocks between the different sections of the ISS. I would also assume that they would close these airlocks while doing the kind of work they are doing to repair the leaks.

So, assuming I'm right (and my assumptions might be wrong,) why do the astronauts need to shelter?

Debris from what? Satellite debris get in that orbit?

This is just not true. There have been leaks due to micrometers in just about every section of the ship at one point or another. A quick search pulls up examples of US modules having issues, especially around interfaces and seals. NASA had a whole investigation between 2018 and 2021 about the recurring issue.

The 10 non-Russian modules have been in vacuum for a quarter century and have done just fine despite facing more debris than in interplanetary space. So yes, this aspect is well tested. This stuff is literally part of the reason why the ISS exists in the first place.

Well, I won't claim to know the answer, but "please do not move between different airlocked sections while this work is underway" sounds a lot like the definition of "shelter" to me
