      "summary": "Reviewed the ARM64 assembly implementation of `bignum_sqr_p521_neon`, which performs p521 field squaring and modular reduction with register arithmetic plus ordinary save/restore prologue and epilogue. I found no install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, or persistence mechanisms in this file.",
