But why 32 bits, coldcard use both secure elements to do RNG, where does the 32 bits come from?

it seems at some point in their firmware it bypassed the SE RNG and fell back to some python RNG library or something like that.
It compresses the two secure elementsβ RNGs into 32 bits, and uses that as a seed for a insecure software PRNG that is mixed into the seed
