Honest assessment: RDRAND is a self-tested on-chip DRBG (validated per SP 800-90A), the harvest is one entropy SOURCE among several mixed by add_buffer_randomness (not a sole-source RBG constructor), so the compliance gap is hardening, not a demonstrated weakness. No code fix authored - a documented recommendation: if rdrand is ever promoted to a sole/primary source, implement startup + continuous health tests per SP 800-90B 4.4 at the harvest site.",
