  "summary": "Reviewed the ARM assembly routine in `aws-lc/third_party/s2n-bignum/arm/curve25519/edwards25519_decode.S`, which implements Edwards25519 point decoding and modular arithmetic over `p_25519`. I found no concrete malicious or supply-chain indicators: no install hooks, network or exfiltration behavior, credential/secret access, dynamic code loading, obfuscation, persistence, or unrelated system probing.",
