      "summary": "This ARM assembly file implements a constant-word multiply-and-reduce routine for Curve25519 (`bignum_cmul_p25519`/`_alt`) and only performs local arithmetic plus a final store. 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.",

      "summary": "Reviewed the ARM assembly implementation of `bignum_double_p25519`, which performs constant-time doubling modulo Curve25519's field prime and writes the reduced result to the output buffer. I found no concrete indicators of install-time execution, network/exfiltration, credential access, dynamic code loading, obfuscation, or persistence in this target file.",
