{
  "summary": "Reviewed this ARM assembly implementation of `bignum_sqrt_p25519`, which performs fixed modular-arithmetic operations for Curve25519 square-root computation and return-value selection. I checked for install-time hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, and persistence, and found no concrete malicious or supply-chain indicators in the target file.",
