      "summary": "Reviewed `src/ec/suite_b/curve.rs`, which defines the Suite B P-256/P-384 curve descriptors and thin wrappers for private-key validation, private-key generation, and public-key derivation. I found no concrete signs of install-time execution, network or credential access, dynamic code loading, obfuscation, persistence, or other supply-chain malicious behavior in this file.",

      "summary": "Reviewed the Suite B ECDH implementation for P-256/P-384 key agreement and its tests. I checked for install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, persistence, and other hidden subprocess execution, and found no concrete malicious or supply-chain indicators in this file.",
