"""Guard: the test suite must NEVER resolve the real database/music_library.db.
Tests exercise modules that call get_database() with no path. If that resolves
to the live DB, test writes can corrupt a real library (this happened, over a
WSL-mounted Windows drive). conftest.py sets DATABASE_PATH to a temp file before
anything imports; these tests prove it sticks for every default-path access.
