{
  "summary": "Reviewed the ARM assembly implementation of `bignum_sqr_p521_neon`, which performs a constant-time P-521 field squaring and stores the reduced result back to the output buffer. I checked for install-time hooks, subprocess or network activity, credential/secret access, dynamic code loading, obfuscation, persistence, and other supply-chain indicators, and found none.",
