{
  "summary": "Reviewed this C++ unit test file, which only reads a local Mach-O test fixture and compares parsed sections, headers, and symbol indices against expected in-memory data. I found no concrete indicators of install hooks, network or exfiltration, credential access, dynamic code loading, obfuscation, or persistence in the target file.\nReviewed `aws-lc/crypto/kyber/pqcrystals_kyber_ref_common/symmetric.h`, a small Kyber symmetric-primitive interface header that only declares XOF/PRF/hash macro bindings for the AES-CTR/SHAKE backends. I checked for install-time execution, hidden subprocesses, network or exfiltration paths, credential access, dynamic code loading, obfuscation, and persistence behavior, and found no concrete malicious or supply-chain indicators in this file.\nReviewed `aws-lc/crypto/rand_extra/getentropy_test.cc`, which is a unit test for `getentropy()` behavior under `OPENSSL_RAND_GETENTROPY`. I found no concrete indicators of install hooks, network or exfiltration, credential access, dynamic code loading, obfuscation, persistence, or other supply-chain abuse in this file.\nReviewed this ARM64 assembly routine for `bignum_neg_p25519`, which performs a constant-time modular negation for Curve25519 field elements and returns the result via registers/memory only. I found no concrete indicators of install-time execution, network/exfiltration, credential access, dynamic code loading, obfuscation, persistence, or other hidden malicious behavior in the target file.\nReviewed `aws-lc/crypto/dilithium/pqcrystals_dilithium_ref_common/fips202.h`, which is a small C header declaring Keccak/SHAKE/SHA3 types, constants, and function prototypes with optional symbol-prefix macros. I checked for install-time hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation/packing, and persistence tampering, and found no concrete malicious or supply-chain indicators in this file.",
