      "summary": "Reviewed this header-only Dilithium rounding interface, which only declares four namespaced function prototypes and preprocessor aliases. I checked for install-time execution, network or credential access, dynamic code loading, obfuscation, and persistence hooks in the target file and found no concrete malicious or supply-chain indicators.",

      "summary": "The target file implements the Dilithium signing API: key generation, detached signing, signature verification, and signed-message opening, using local randomness plus SHAKE-based hashing and pack/unpack helpers. I checked for install-time hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, and persistence mechanisms, and found no concrete malicious or supply-chain indicators.",
