      "summary": "`aws-lc/crypto/bio/socket_helper.c` is a small platform-specific socket utility that resolves host/port pairs, creates sockets, toggles nonblocking mode, and reads socket errors. I checked it for install-time hooks, credential access, hidden downloads, dynamic code loading, obfuscation, persistence, and exfiltration behavior and found no concrete malicious or supply-chain indicators.",
