  "summary": "Reviewed `aws-lc/crypto/x509/v3_alt.c`, which implements X509 subject/issuer alternate-name parsing, copying, and printing for certificate extensions. No concrete malicious or supply-chain indicators were found: I checked for install hooks, network or exfiltration behavior, credential or secret access, dynamic code loading, obfuscation/packing, and persistence or environment tampering, and none were present.\nReviewed the ARM assembly implementation of `sm2_montjdouble_alt`, which performs SM2 point doubling using local stack temporaries and fixed big-number arithmetic macros. I checked for install hooks, hidden subprocesses, network or exfiltration behavior, credential/env access, dynamic code loading, obfuscation, and persistence, and found no concrete malicious or supply-chain indicators in this file.",
