      "summary": "Reviewed the ARM assembly implementation of `bignum_kmul_16_32`, including its local 8x16 multiply helper. It is a deterministic big-number multiplication routine with register saves/restores and arithmetic only; I found no install hooks, network or exfiltration paths, credential access, dynamic code loading, obfuscation, persistence, or other supply-chain compromise indicators in this file.",
