      "summary": "Reviewed the ARMv8 assembly implementation of P-521 Jacobian point addition in `p521_jadd_alt.S`, which performs only finite-field arithmetic and constant-time conditional selection for elliptic-curve coordinates. I found no install hooks, subprocesses, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, or persistence in this target file.",
