      "summary": "Reviewed the ARMv4 Linux32 ChaCha20 assembly implementation in `pregenerated/chacha-armv4-linux32.S`. It is a standalone crypto routine with arithmetic/bytewise data movement only; I found no concrete indicators of install-time execution, network/exfiltration, credential access, dynamic code loading, obfuscation, persistence, or other hidden payload behavior.",
