AI Summary: This issue proposes refactoring existing tests for false positive validation in the `tests/test_validation_false_positives.py` file. The goal is to make these tests more lightweight and faster by simplifying fixtures, focusing on core normalization problems, reducing dependencies, and improving error reporting. This will help in better identifying and fixing validation issues related to multiline text, punctuation variations, and sentence ending differences.
