fx_exp_test.nx

fx_exp_test.nx -- KAT for the fixed-point base-2 exponential family (fx_exp2 / fx_exp10 / fx_expe / fx_pow), the inverse of fx_log2. Run via the sovereign native lane: _offc/nx_compile_x86_native.elf fx_exp_test.nx > t.s as t.s -o t.o && ld -o t.elf t.o && ./t.elf ; echo $? Exit 0 = all assertions PASS; exit N = assertion N failed. Powers of two are EXACT; irrationals/round-trips are bounded (the fixed-point algorithm is deterministic, so the band is a tight correctness window, not a fudge factor). Prints the key values first.
