      "summary": "`aws-lc/crypto/bio/connect.c` implements the socket-connect BIO: it parses host and port strings, opens and configures a TCP socket, and drives synchronous or nonblocking connect/read/write state. I checked this file for install-time hooks, network exfiltration beyond the expected connection, credential access, hidden dynamic code loading, obfuscation, persistence, and other supply-chain indicators, and found no concrete malicious behavior.",

      "summary": "Reviewed `aws-lc/crypto/bio/errno.c`, which only exposes `bio_errno_should_retry()` and checks a small set of local `errno` values to decide whether a BIO operation should be retried. I found no concrete malicious or supply-chain indicators in this file: no install-time hooks, network or exfiltration code, credential access, dynamic code loading, obfuscation, or persistence behavior.",

      "summary": "This file implements the fd-backed BIO adapter for AWS-LC/BoringSSL, wiring existing file descriptors into read, write, seek, tell, and close operations.
