{
  "summary": "`src/cpu.rs` is a CPU feature-detection and caching module that uses compile-time `cfg` dispatch to select ARM/Intel/backstop featureflag implementations. I checked it for install-time hooks, network or exfiltration, credential access, dynamic code loading, obfuscation, persistence, and hidden subprocess execution, and found no concrete malicious or supply-chain indicators in this file.\nReviewed the generated x86 Montgomery multiplication routine in `pregenerated/x86-mont-win32n.asm`, including its stack setup, arithmetic loops, and trailing embedded bytes. I found no concrete indicators of install-time execution, network/exfiltration, credential access, dynamic code loading, obfuscation, or persistence; the file appears to be a normal crypto math implementation with a small embedded copyright string.\nReviewed `src/ec/suite_b/ecdh.rs`, which implements ECDH key agreement for P-256 and P-384 plus unit tests for key-generation edge cases. I found no concrete indicators of install-time execution, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, or persistence in this file.\nReviewed the generated x86 ELF assembly in pregenerated/x86-mont-elf.S, including the Montgomery multiplication routine and the trailing embedded ASCII metadata. I found no concrete malicious or supply-chain indicators: no install hooks, network or exfiltration logic, credential access, dynamic code loading, obfuscation/deobfuscation, or persistence behavior.\nReviewed `tests/agreement_tests.rs`, which contains ECDH agreement tests and helper routines for curve handling, key generation, and hex parsing. I checked for install hooks, network or exfiltration behavior, secret access, dynamic code loading, obfuscation/deobfuscation, persistence, and other hidden payload execution, and found no concrete malicious or supply-chain indicators.",
