      "summary": "Reviewed the x86-64 assembly implementation of `bignum_invsqrt_p25519`, which performs modular inverse-square-root arithmetic for Curve25519 using only local register/stack operations and internal helper routines. I found no concrete malicious or supply-chain indicators in this file: no install hooks, no network or exfiltration, no credential/secret access, no dynamic code loading, no obfuscation, and no persistence behavior.",
