"""
ANAF denumire_override Regression Tests
========================================
When creating a new PJ partner, use the official ANAF name (denumire_anaf)
instead of the (potentially misspelled) GoMag company_name.

Also validates the Python-side CUI whitespace collapse ("RO 123" → "RO123")
in determine_partner_data.

Run:
    cd api && python -m pytest tests/test_anaf_name_override.py -v
