      "summary": "Reviewed `src/deprecated_constant_time.rs`, which is a tiny deprecated wrapper that forwards `verify_slices_are_equal` to an internal constant-time comparison helper. I found no concrete malicious or supply-chain indicators in this file, and it contains no install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, or persistence behavior.",

      "summary": "Reviewed `src/deprecated_test.rs`, which only defines a `test_file!` helper macro that embeds local test fixtures with `include_str!` and reexports deprecated test utilities/types.

I checked this file for install-time execution, network or exfiltration, credential access, dynamic code loading, obfuscation, persistence, and other supply-chain indicators, and found no concrete malicious behavior.",
