      "summary": "Reviewed the ARM assembly in `aws-lc/third_party/s2n-bignum/arm/p521/p521_jdouble_alt.S`, which implements P-521 Jacobian point doubling and related field-arithmetic macros using only local register/stack operations. I found no concrete indicators of install-time execution, network or credential access, dynamic code loading, obfuscation, persistence, or other supply-chain compromise behavior.",
