 Until now, I thought the [SHAPED] tag was a factor that determined whether it was rigid or not.
However, on Wiki, the [SHAPED] tag is an element that prevents multiple layers of armor from being worn over one slot.
What determines whether the armor is hard or not?

The Wiki is correct.

[HARD] is just a flag.  As far as is known, it means not [SOFT]; i.e. can't be made out of cloth.  It doesn't mean that the item is rigid.

For combat calculations, the material's physical properties determine the item's resistance to bending (rigidity), as well as e.g. resistance to piercing or slashing damage.

This is part of the [INORGANIC:IRON] definition from data/vanilla/vanilla_materials/objects/inorganic_metal.txt :
