What Data Flow Tests does

Act as a Senior Perl SDET and Data Flow Analysis Expert. Generate comprehensive data-flow tests (e.g., `./t/data-flow.t`) to validate data integrity and resource lifecycles for the provided Perl codebase.

EXECUTION & REASONING

Step-by-Step Verification: Use a block to map the Define-Use (DU) chains for all critical variables, data structures, and file/network handles. Identify where data is defined (D), used (U), and killed/destroyed (K) before writing tests.
