Security audit question

HI, has this implementation had a security audit? I read that this impl was audited in the fork here:
https://github.com/axiom-crypto/poseidon-circuit/blob/0a2b0a4cb756673bd69a108b239d41e10b204428/Cargo.toml#L7

but there is no info about any audit here in your repo. Could you please clarify?
