  "summary": "Reviewed `aws-lc/crypto/fipsmodule/rand/entropy/tree_drbg_jitter_entropy_isolated_test.cc`, a GoogleTest C++ test file that exercises tree-DRBG jitter entropy initialization, reseeding, forking, and threading behavior. I found no concrete malicious or supply-chain indicators in this file: there are no install hooks, network or exfiltration calls, credential or secret access, dynamic code loading, obfuscation/deobfuscation, or persistence/environment-tampering behavior.\nReviewed the ARM assembly implementation of `p256_montjadd_alt`, which performs only P-256 Montgomery-Jacobian point addition and stack-local field arithmetic before storing the computed coordinates back to the output buffers. I found no concrete indicators of install-time hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, persistence, or other hidden payload behavior in this file.",
