  "summary": "Reviewed the target file as auto-derived x86_64 AVX2 assembly for `mlkem_polyvec_basemul_acc_montgomery_cached_asm_k2`, which performs fixed arithmetic on input/output buffers. I found no concrete malicious or supply-chain indicators: there are no install hooks, network or exfiltration calls, credential or secret access, dynamic code loading, obfuscation/decoding pipelines, or persistence/tampering behavior in this file.\nReviewed `aws-lc/crypto/fipsmodule/ec/p521.c`, which implements P-521 elliptic-curve field and point arithmetic using either Fiat-crypto or s2n-bignum backends. I found no concrete malicious or supply-chain indicators in this file: no install hooks, network or exfiltration code, hidden downloads, credential access, obfuscation, persistence, or dynamic payload loading.",
