{
  "summary": "Reviewed this ARM assembly source, which defines three read-only constants/arrays (`x`, `y`, `z`) and two small functions (`f`, `g`) that index the arrays and add the results. I checked for install-time hooks, network or exfiltration code, credential/secret access, dynamic code loading, obfuscation, persistence, and other hidden execution paths, and found no concrete malicious or supply-chain indicators in this file.\nReviewed this x86-64 assembly routine for secp256k1 Montgomery conversion; it appears to be a straight arithmetic implementation with ABI shims and no concrete indicators of install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, or persistence tampering.\nReviewed `builder/cc_builder/apple_x86_64.rs`, which is a static list of Apple x86_64 assembly source paths for the build system. I found no concrete indicators of install hooks, network or exfiltration, credential access, dynamic code loading, obfuscation, persistence, or other supply-chain compromise behavior in this file.\nReviewed `builder/cc_builder/linux_x86_64.rs`, which is a static Rust constant listing x86_64 assembly source paths for the crypto build. I checked for install hooks, hidden subprocess execution, network or exfiltration logic, credential access, dynamic code loading, obfuscation, and persistence, and found no concrete malicious or supply-chain indicators in this file.\nI reviewed `src/lib.rs`, which is a thin Rust FFI wrapper that conditionally includes pre-generated bindings, exposes a few error-bit helper functions, and calls `CRYPTO_library_init()` from `init()`. I found no concrete malicious or supply-chain indicators in this file: there are no install hooks, network or exfiltration paths, secret-access logic, dynamic remote code loading, obfuscation, or persistence behavior.",
