{
  "summary": "Reviewed `aws-lc/crypto/base64/base64_test.cc`, which is a deterministic GoogleTest suite for base64 encode/decode behavior and edge cases. I checked for install hooks, network or exfiltration, credential access, dynamic code loading, obfuscation, persistence, and other payload-like behavior, and found no concrete malicious or supply-chain indicators in this file.\nReviewed `aws-lc/crypto/err/err_test.cc`, which contains unit tests for AWS-LC error-queue and error-string behavior. I checked for install hooks, hidden subprocess execution, network or exfiltration paths, credential or secret access, dynamic code loading, obfuscation, and persistence/tampering, and found no concrete malicious or supply-chain indicators.\nReviewed `aws-lc/crypto/poly1305/poly1305_arm.c`, which is a NEON Poly1305 implementation and buffer/state handling code for MAC computation. I checked for install-time hooks, network or exfiltration behavior, credential/secret access, dynamic code loading, obfuscation, and persistence tampering, and found no concrete malicious or supply-chain indicators in this file.\nReviewed this ARM assembly implementation of `sha3_keccak_f1600_alt2`, which is a self-contained Keccak-f1600 permutation routine for SHA3. I checked for install-time hooks, network/exfiltration, credential or secret access, dynamic code loading, obfuscation/packing, persistence, and hidden subprocess execution; none were present in this target file.",
