      "summary": "Reviewed the Fuchsia-specific RNG shim in aws-lc/crypto/rand_extra/fuchsia.c. It only forwards CRYPTO_sysrand and CRYPTO_sysrand_for_seed to zx_cprng_draw under OPENSSL_RAND_FUCHSIA, with no install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, or persistence behavior present in this file.",

      "summary": "Reviewed this gtest source for the getentropy implementation. It only exercises entropy generation, zero/nonzero comparisons, memcpy sanity, and the >256-byte error path; I found no concrete indicators of install-time execution, network/exfiltration, credential access, dynamic code loading, obfuscation, or persistence.",

I checked for install-time execution, network or exfiltration, credential access, dynamic code loading, obfuscation, and persistence, and found no concrete malicious or supply-chain indicators in this file.",
