Subject: [PATCH 1/2] Fix: Remove duplicate test methods for coord/variable
name collision
Removes two unintentionally duplicated instances of the `test_name_conflict_variable_and_coord` test method from the `TestNested` class in `tests/model/test_core.py`.
This ensures the test suite is clean and avoids redundant test executions.
