  "summary": "Reviewed the ARM64 assembly implementation of `p521_jmixadd_alt`, which performs P-521 Jacobian mixed-point addition using fixed bignum arithmetic and conditional moves. I found no concrete indicators of install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation/deobfuscation, persistence tampering, or other hidden payload execution in this file.",
