ML-DSA-65 verification failure?

openssl genpkey -provider=oqsprovider -provider=default -algorithm mldsa65 -out mldsa65.key

where hello.txt contains "hello world" - 6865 6c6c 6f20 776f 726c 640a
Copy contents of PUB and SIG into python implementation from https://github.com/GiacomoPope/dilithium-py

from dilithium_py.ml_dsa import ML_DSA_65

pub_string="PUB"
sig_string="SIG"

pub=bytes.fromhex(pub_string);
sig=bytes.fromhex(sig_string);

print("PUB len=",len(pub))
print("SIG len=",len(sig))

print(ML_DSA_65.verify(pub, b"hello world\n", sig))

Verification fails. Why?

Verification fails. Why?

That's not surprising as final MLDSA is not yet integrated (see open-quantum-safe/liboqs#1891).

Sigh.. So why call it MLDSA if its not...

Point taken. My fault. I assumed we'd be able to do all in one go but didn't.
