Three things need attention before anything else: 1. **P003 is broken as-is** — active, no schedule, no upsert key. It will never run, and if it does it can't complete the load. 2. **GDPR exposure is real** — no data_classification field means CRM PII (P001, P004) has zero metadata-level governance hook. 3. **The 7am SLA is invisible to the estate** — no audit log, no SLA field, no dependency ordering between P001 and P002. A failure at 01:30 won't be detected until analysts arrive at 7. The DDL at the bottom is copy-paste ready. Priority 1–3 additions are the ones to ship first. الله يباركلك 🎯
