  "summary": "Reviewed this x86-64 assembly implementation of `edwards25519_epdouble_alt`, which performs finite-field arithmetic for Curve25519 point doubling using local registers and stack temporaries. I checked for install-time hooks, network or exfiltration behavior, credential/secret access, dynamic code loading, obfuscation, persistence, and other hidden execution paths, and found no concrete malicious or supply-chain indicators in this target file.\nReviewed `aws-lc/crypto/fipsmodule/modes/internal.h`, which is a C header of crypto mode declarations and architecture-specific GCM/POLYVAL interfaces. I found no concrete malicious or supply-chain indicators in this file: there are no install hooks, network or exfiltration code, credential access, dynamic code loading, obfuscation/decoding pipelines, or persistence/tampering behavior here.",
