{
  "summary": "Reviewed `aws-lc/crypto/pool/internal.h`, a small C header that only declares `CRYPTO_BUFFER`/pool internals, mutex/hash fields, and C++ linkage guards. I found no concrete malicious or supply-chain indicators in the file: no install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, or persistence behavior.\nReviewed `aws-lc/crypto/rand_extra/forkunsafe.c`, which only gates an internal fork-unsafe buffering flag behind a mutex and returns a disabled default on Windows. I checked for install-time execution, network or exfiltration, credential access, dynamic code loading, obfuscation, and persistence behavior, and found no concrete malicious or supply-chain indicators in this file.\nReviewed this header-only API declaration file for fork-generation detection and a test-only helper. It contains no install hooks, network or exfiltration logic, credential access, dynamic code loading, obfuscation, persistence, or other supply-chain indicators.\nReviewed `aws-lc/crypto/rand_extra/pq_custom_randombytes.c`, which is a small test-only random-bytes wrapper that either uses `RAND_bytes` or a deterministic CTR-DRBG when explicitly enabled for testing. I checked for install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, and persistence behavior and found no concrete malicious or supply-chain indicators.\nReviewed `aws-lc/include/openssl/poly1305.h`, which is a small C header exposing the Poly1305 API declarations and comments only. I checked for install-time hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, and persistence tampering, and found no concrete malicious or supply-chain indicators in this file.",
