Test Coverage Reporting and Validation

**Is your feature request related to a problem? Please describe.**

**Describe the solution you'd like**

**Describe alternatives you've considered**

**Additional context**

The issue body is an empty feature-request template and names no files, tests, or entry points. Start by inspecting the repository's Java test and build configuration to determine the intended coverage reporting and validation scope. Done criteria are not specified; clarify the desired report, thresholds, validation behavior, and CI integration before implementation.
