hatch cut in the chipboard reveals a dwarf-wall with a piece of
damp-proof course on top of it, and a gap of about 3 to 5mm between
the dpc and the joists.

It would apear that the majority of posts on this group lately are not
seriously concerned with diy.

Anyway to business:

No-one has sugested why the wall no longer supports the floor.

Is there a chance you have missed the obvious and that the packing that
was supporting it has fallen off the wall?

Put a strip of exterior grade 1/4 ply on top of the wall. Put it on a
layer of damp proofing. Make it wide enough to put a few screws up into
the floor or screw down through the floor into the ply.
