      "summary": "Reviewed the SHA-3 implementation in `aws-lc/third_party/jitterentropy/jitterentropy-library/src/jitterentropy-sha3.c`, including the Keccak rounds, absorb/finalize logic, self-test, and context allocation/free paths. I found no concrete malicious or supply-chain indicators in this file: no install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, persistence, or unrelated system probing.",

      "summary": "Reviewed this ARM assembly implementation of `bignum_add_p25519`, which performs constant-time modular addition for Curve25519 field elements and only reads/writes its input/output buffers.
