{
  "summary": "Reviewed src/probestack.rs, which contains platform-specific inline assembly for Rust's __rust_probestack stack-probe intrinsic on x86/x86_64, including ELF, Mach-O, and UEFI variants. I checked the file for install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, persistence, and hidden subprocess execution, and found no concrete malicious or supply-chain indicators.\nReviewed `src/mem/x86_64.rs`, which implements x86_64 memory primitives (`copy_forward`, `copy_backward`, `set_bytes`, `compare_bytes`, `c_string_length`, and `rep_param`) using inline assembly and SSE intrinsics for performance. I checked for install hooks, network or exfiltration behavior, credential/secret access, dynamic code loading, obfuscation, and persistence/tampering, and found no concrete malicious or supply-chain indicators in this file.\nReviewed `src/hexagon/dfmul.s`, a Hexagon assembly implementation of double-precision floating-point multiply with local branches for NaN, infinity, zero, overflow, and underflow handling. I found no concrete indicators of install-time execution, network/exfiltration, credential access, dynamic code loading, obfuscation, or persistence in this target file.",
