{
  "summary": "Reviewed this ARM64 assembly routine for SM2 triple-and-reduce arithmetic. It is a straight-line big-number implementation with only register math, loads, stores, and constant-time conditional masking; I found no install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, or persistence behavior in the target file.\nReviewed this Perl perlasm generator for AArch64 big-number add/sub assembly. It only resolves a local `arm-xlate.pl`, opens a pipe to the Perl interpreter for code generation, and emits straight-line assembly; I found no concrete indicators of install hooks, network or exfiltration behavior, credential access, hidden downloads, obfuscation, or persistence.\nReviewed `aws-lc/include/openssl/arm_arch.h`, which is a CPU-feature header defining ARM/AArch64 capability and MIDR helper macros for assembly and dispatch logic. I found no concrete supply-chain indicators in this file: no install-time hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, or persistence behavior.\nReviewed a small hand-written x86-64 assembly routine that conditionally negates a 521-bit field element modulo p_521. It is straight-line arithmetic only, with no install hooks, network or exfiltration, credential access, dynamic code loading, obfuscation, or persistence behavior present in the target file.\nReviewed a hand-written x86-64 assembly routine implementing `bignum_cmul_p256k1`, which performs modular multiplication for secp256k1 using register arithmetic and ABI shims only. I found no concrete indicators of install-time execution, network/exfiltration, credential access, dynamic code loading, obfuscation, or persistence in this target file.",
