{
  "summary": "Reviewed `aws-lc/crypto/poly1305/internal.h`, which is a small C header exposing Poly1305 NEON function declarations behind platform macros. I checked for install-time execution, network/exfiltration, credential access, dynamic code loading, obfuscation, and persistence behaviors and found no concrete malicious or supply-chain indicators in this file.\nReviewed `aws-lc/crypto/fipsmodule/kdf/internal.h`, which is a small internal KDF header defining constants, context structs, and function prototypes for digest/HMAC-based KDF variants. I found no concrete indicators of supply-chain compromise or malicious behavior in this file: no install hooks, network or exfiltration code, credential access, dynamic code loading, obfuscation, or persistence logic.\nReviewed `aws-lc/third_party/jitterentropy/jitterentropy-noise.h`, which is a small C header that only declares jitterentropy-related functions and include guards. I found no concrete indicators of install hooks, network or exfiltration, credential access, dynamic code loading, obfuscation, or persistence in this target file.\nReviewed this header-only Dilithium packing API declaration file. It contains only function prototypes and namespace macros for key/signature pack and unpack routines, with no install hooks, network or exfiltration code, credential access, dynamic code loading, obfuscation, or persistence behavior present in the target file.\nReviewed the Fuchsia-specific RNG shim in `aws-lc/crypto/rand_extra/fuchsia.c`. It only defines `CRYPTO_sysrand` and `CRYPTO_sysrand_for_seed` to call the platform `zx_cprng_draw` syscall under `OPENSSL_RAND_FUCHSIA`, and I found no concrete indicators of install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, or persistence.",
