      "summary": "Reviewed the ARM assembly implementation of `bignum_montsqr_p521_alt`, which performs a fixed Montgomery-style squaring and reduction for P-521 using only integer arithmetic and register/memory moves. I found no concrete indicators of install-time execution, network or exfiltration behavior, credential/secret access, dynamic code loading, obfuscation, or persistence tampering in this target file.",
