      "summary": "Reviewed an x86-64 assembly implementation of modular square root over p25519, including the helper multiply and repeated-square routines it calls. I checked for install-time hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, persistence, and hidden subprocess execution; none were present in this file.",

      "summary": "Reviewed this x86-64 assembly routine that implements modular subtraction for Curve25519 field elements (`bignum_sub_p25519`). It contains only fixed arithmetic and ABI/setup macros; I found no concrete indicators of install-time execution, network or exfiltration, credential access, dynamic code loading, obfuscation, persistence, or other supply-chain abuse.",
