  "summary": "Reviewed `aws-lc/third_party/jitterentropy/jitterentropy-library/jitterentropy-base-user.h`, which is a platform-specific entropy/timing helper for jitterentropy with conditional inline assembly, FIPS-state checks, cache-size probing, and secure-memory wrappers. 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, or persistence behavior.\nReviewed the target x86-64 assembly source for `secp256k1_jadd_alt`, which implements Jacobian point addition and final conditional multiplexing for secp256k1 field elements. I found no concrete malicious or supply-chain indicators in this file: there are no install hooks, network or exfiltration paths, credential access, dynamic code loading, obfuscation, or persistence behavior; the code is limited to arithmetic, register saving/restoring, and stack-local temporaries.",
