  "summary": "Reviewed the AArch64 SHA-256 assembly implementation in `aws-lc/generated-src/win-aarch64/crypto/fipsmodule/sha256-armv8.S`, including the conditional dispatch-test path and the hand-written/generated code paths. I found no concrete malicious or supply-chain indicators: there are no install hooks, network or exfiltration calls, credential/secret access, dynamic code loading, obfuscation/deobfuscation pipelines, or persistence/tampering behavior in this file.",
