What should be expected from a guardian ad litem home inspection?

Yep, this goes along with the previous question.

This makes round 3 of bogus accusations. I keep a tidy house, I’m a little bit of a neat freak by nature, but I am in an absolute panic over an inspection tomorrow morning.
Can anyone tell me what it entails? What will it be like? Are they going to just wander around opening my cupboards, or will I just show them around?

I have no idea what to expect and not knowing is stressing me out more than anything.
