{
  "summary": "Reviewed the ARM assembly in `edwards25519_pdouble_alt.S`; it implements local edwards25519 point-doubling arithmetic with fixed macros and register/stack operations only. I found no concrete indicators of install hooks, network or secret access, dynamic code loading, obfuscation, persistence, or other supply-chain style payload behavior in this file.\nReviewed this ARM64 assembly routine implementing a 8-limb bignum square and its carry-propagating cross-term accumulation. I found no concrete malicious or supply-chain indicators in the target file: there are no install hooks, network or exfiltration paths, credential access, dynamic code loading, obfuscation/deobfuscation, or persistence mechanisms.\nReviewed `aws-lc/crypto/x509/x509name.c`, which implements X.509 name and name-entry helpers for lookup, insertion, deletion, and ASN.1/string conversion. I checked for install-time execution, network or exfiltration behavior, credential or environment access, dynamic code loading, obfuscation, and persistence, and found no concrete malicious or supply-chain indicators in this file.",
