## Known Limitations

1. **BA fuer Arbeit adapter** — employment metrics (unemployment rate, job openings, BA-X) currently failing; adapter needs fixing
2. **ZEW adapter** — economic sentiment metrics currently failing
3. **Some Destatis tables** — RETAIL, PPI, IMPORT_PRICE, AVG_WAGE, GINI, MEDIAN_INC, POVERTY failing; table codes may need correction
4. **DE_MORTGAGE** — returns 13% (2003), series ID suspect; actual current rate ~3.5%
5. **Unit formatting** — DE_LABFORCE and DE_POP display raw values; format fields need correction
