{
  "summary": "Reviewed the auto-derived AVX2 assembly in `polyvec_basemul_acc_montgomery_cached_asm_k4.S`, which implements a fixed-pattern polynomial vector multiply/accumulate using only register arithmetic plus bounded loads/stores between its three input pointers and output pointer. I found no concrete supply-chain indicators in this file: no install hooks, network or exfiltration paths, credential access, dynamic code loading, obfuscation, persistence, or hidden subprocess execution.",
