  "summary": "Reviewed aws-lc/crypto/fipsmodule/ec/simple.c, which contains low-level elliptic-curve field and point helpers for curve setup, point comparison, serialization, and constant-time curve checks. I found no concrete malicious or supply-chain indicators: no install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation/deobfuscation, persistence, or subprocess execution in the target file.\nReviewed the generated x86_64 assembly implementation of `beeu_mod_inverse_vartime` in `p256_beeu-x86_64-asm.S`. It appears to be a self-contained finite-field/P-256 routine with no concrete signs of install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, or persistence tampering.\nReviewed the generated AArch64 GHASH assembly in `aws-lc/generated-src/ios-aarch64/crypto/fipsmodule/ghash-neon-armv8.S`. It consists of straight-line cryptographic vector operations plus a static constant table; I found no concrete indicators of install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, persistence, or other hidden payload behavior in this target file.",
