It alters `make_hard_case` to generate more realistic target and UTXO amounts while keeping search attempts at the 100,000 evaluation limit, and adds assertions verifying the evaluated count and solution properties.",

It also adds assertions to verify that a valid solution is produced. As an internal benchmark adjustment, it has marginal importance. One reviewer tested and verified the behavior before a minor follow-up parameter adjustment by the author."
