  "summary": "Reviewed the target file `secp256k1_jmixadd.S`, which is a hand-written x86-64 assembly routine for secp256k1 mixed Jacobian point addition using deterministic field-arithmetic macros and ABI prologue/epilogue handling. I found no concrete malicious or supply-chain indicators in this file: there are no install hooks, network or exfiltration code, credential access, dynamic code loading, obfuscation/deobfuscation, persistence changes, or hidden subprocess execution.\nReviewed `aws-lc/crypto/trust_token/internal.h`, which is an internal C/C++ header declaring Trust Token, PMBTokens, and VOPRF data structures and APIs. I found no concrete malicious or supply-chain indicators in this file: no install hooks, subprocess execution, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, or persistence logic.",
