I thought substr_compare returned TRUE for matches.

If I remember correctly, since "bar" starts at position 3 in "foobar", it should return 0 because they match.

I feel like it could be -1 or 1 depending on the comparison, but I can't recall the exact details.

I remember practicing a similar question, and I think it returns 0 when the substrings match exactly.

I think the function compares substrings, but I'm not sure what the starting position affects.

Okay, let's see - placement, layering, and integration are the main stages, so I'll check those options.

Ah, I think I've seen this kind of issue before. Recreating the guestshell might be the way to go, but I'll double-check the other options just to be sure.

I'm not entirely sure about this one. The question mentions tracking the cost of equipment usage, so I'm wondering if Usages might be the right expenditure type class. I'll need to think this through a bit more.
