      "summary": "`aws-lc/generated-src/linux-ppc64le/crypto/test/trampoline-ppc.S` is a generated PowerPC64 assembly trampoline used for ABI/register-clobber tests, with functions that save and restore CPU state and deliberately mutate registers. I checked it for install-time execution, network or secret access, dynamic code loading, obfuscation, persistence tampering, and other hidden payload behavior, and found no concrete malicious or supply-chain indicators.",
