  "summary": "Reviewed aws-lc/crypto/x509/v3_ncons.c, which implements X.509 name-constraints parsing, printing, and matching for certificates. I checked this file for install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, and persistence behavior, and found no concrete malicious or supply-chain indicators.\nReviewed the AArch64 assembly implementation of `bignum_montmul_p521_alt`, which performs local 521-bit Montgomery-style modular multiplication and register save/restore only. I found no concrete indicators of install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, or persistence in this target file.",
