      "summary": "`aws-lc/crypto/dsa/dsa_test.cc` is a DSA unit-test file that builds sample parameters, signs/verifies fixed digests, checks malformed signatures, and exercises edge cases like missing keys and infinite-loop guards. I reviewed it for install-time execution, network/exfiltration, credential access, dynamic code loading, obfuscation, and persistence, and found no concrete malicious or supply-chain indicators.",

      "summary": "Reviewed `aws-lc/crypto/dynamic_loading_test.c`, a small C test that exercises `dlopen`/`dlclose`, `dlsym`, and pthread cleanup around AWS-LC thread-local teardown. I found no concrete malicious or supply-chain indicators in the target file: there are no install hooks, network or exfiltration paths, credential access, obfuscation/deobfuscation, persistence changes, or dynamic code-loading behavior beyond the explicit local test load of a supplied shared library path.",
