  "summary": "Reviewed `aws-lc/crypto/stack/stack.c`, which implements the OpenSSL-compatible stack container API for allocation, insertion/deletion, sorting, copying, and freeing pointers. I checked for install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation/deobfuscation, and persistence tampering, and found no concrete malicious or supply-chain indicators in this file.\nI reviewed aws-lc/crypto/fipsmodule/ecdsa/ecdsa_test.cc, which is a C++ unit test for ECDSA signing and verification across built-in curves and file-driven test vectors. I found no concrete malicious or supply-chain indicators in the target file: no install hooks, network or exfiltration code, credential or secret access, dynamic code loading, obfuscation, persistence, or hidden subprocess execution.",
