Tested BMW, Stadt Koeln, BfDI, Sparkasse, Caritas, TUEV Sued,
Spiegel, ETO Gruppe, EUIPO. Key findings:
- Stadt Koeln + ETO Gruppe best (95% correctness)
- BMW, Sparkasse, Spiegel genuinely deficient (verified)
- EUIPO uses EU Regulation 2018/1725, not GDPR — needs separate checklist
- ~0-2 false positives per website after LLM verification
7 regex fixes emerged from batch testing (soft hyphens, word
insertions, numbered headings, German section names, etc.)
