did the building inspector miss that the house's floor are flimsy boards?

Hello.

My house is on piers on a rock.
I stood underneath and took a photo of the bedroom floor, and mineral wool is peeking through gaps where it is coming loose.
help!!!...
shouldn't the floor be made of thick core wood?
these thin floorboards look wrong, bent like thin paper where mineral wool is freely exposed for moisture to penetrate.
a building inspector checked before the house was purchased without any remarks.

What you see is the insulation in your joist and the boards that protect the insulation from the wind and from falling down. So, it's not your floor you're seeing in the true sense

shouldn't the floor be core wood at the bottom towards the ground?

You have studs lying between the boards with insulation that is of solid wood, on top of them is possibly chipboard flooring and then your visible floor.

There's no requirement for that. What you see are, as mentioned, subfloor boards, maybe just made of masonite. Common in many simpler houses with pillar foundations.

You have joists lying between the boards with insulation that is made of solid timber, on them, in turn, for example, you have chipboard flooring and then your visible floor.

mineral wool should never be exposed to damp rainy air under the house due to mold risk?

The troax bottom plate doesn't protect much against it anyway; you should probably read up on outdoor air-ventilated constructions, as it will make it easier to understand how it all fits together. The insulation will generally maintain the same moisture level as the surrounding environment, so to change that, you need to study up to avoid making things worse mold won't grow unless the conditions are favorable, and if you don't see any mold, you don't need to worry in that regard.

There is no requirement for such things. What you see are, as mentioned, lower deck boards, maybe just made of masonite. Common in many simpler houses with a pier foundation.

thank you.
what do you recommend I do since the boards have bent like bananas and mineral wool is exposed to the wet, damp rock underneath due to rain now?

Screw boards across as well.

Looks like asfaboard. That's probably the most common construction in the last 30 years? The problem is that the boards bend over time, so you have to insert some planks between the existing ones to push up the stuff.
