Yes, you install something similar to:

Got it, I have got confused with "slab on ground" and what the freeboard was.
Still interesting why there are no piers.

My understanding that as long as the slab is built on top of a freeboard (similar to pods, used for flood protection), this is just another name for the waffle…

Yes.
The report should say: site classified as P due to ..., but soil class is ... (M/H1/H2, etc.)

P class simply means the site is problem site due to some reason (e.g. trees, fill, etc.).
Soil classification should be specified in your geotech report separately.

Why would anyone want flyscreen on the doors at all?
You generally do not use doors for ventilation.

Old wood in retained land fill

Like you said before, the wood with rot and can potentially structurally affect the soil behind the wall.
Gravel will be needed for the drainage.

you would need to remove the timber (and any organical material per se) and put low aggregate gravel such as blue metal behind the wall.

As warm air passed through the insulation and air gap formed by the buttons, it will cool down, so, in theory, there shouldn't be any condensation issues.
