{
  "summary": "Reviewed `src/int/specialized_div_rem/delegate.rs`, which is a Rust macro plus a SPARC-specific `u128` division routine implemented with shift/subtract logic and delegated smaller-width division helpers. I checked for install hooks, network or exfiltration paths, credential or environment access, dynamic code loading, obfuscation, persistence, and other hidden execution behavior; none were present in this file.\nThe target file is a pure `f64` error-function implementation adapted from FreeBSD libm, using fixed polynomial approximations plus `exp`, `fabs`, and bit-level helpers for edge cases. I checked for install-time hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, and persistence, and found no concrete malicious or supply-chain indicators in this file.\nReviewed `src/int/big.rs`, which implements 256-bit signed and unsigned integer helpers plus widening/bitwise operations for `u128`/`i128`. I found no concrete malicious or supply-chain indicators in this file: there are no install hooks, network or exfiltration calls, credential access, dynamic code loading, obfuscation/deobfuscation pipelines, or persistence/environment tampering behavior.\n`src/arm_linux.rs` is a low-level ARM Linux `compiler_builtins` implementation of atomic intrinsics using kernel user-helper entry points and inline `ldr` for aligned loads. I reviewed it for install-time execution, hidden subprocesses, network/exfiltration, credential access, dynamic code loading, obfuscation, and persistence, and found no concrete malicious or supply-chain indicators in this file.",
