  "summary": "Reviewed `aws-lc/crypto/hrss/hrss_test.cc`, a gtest file that exercises HRSS polynomial inversion/multiplication, key generation, encapsulation/decapsulation, and ABI scratch-space checks. I found no concrete indicators of install hooks, network or exfiltration, credential access, dynamic code loading, obfuscation, persistence, or other supply-chain compromise behavior in this file.\nReviewed the x86-64 assembly implementation of `edwards25519_pepadd_alt`, which performs elliptic-curve field arithmetic using local macros and register/stack bookkeeping only. I found no concrete malicious or supply-chain indicators in the target file: no install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, persistence, or hidden subprocess execution.",
