      "summary": "Reviewed `aws-lc/crypto/bio/file.c`, which implements the BIO file backend for opening, reading, writing, seeking, flushing, and closing `FILE *` streams, including filename-to-mode mapping and Windows text/binary mode handling. I found no concrete indicators of install-time execution, network/exfiltration, credential access, dynamic code loading, obfuscation, persistence, or other supply-chain malicious behavior in this file.",
