+Perfect. Design the full pipeline architecture but keep the logic layer completely pluggable. Here's the end-to-end structure:
+
+**Data Flow Architecture:**
+
+```
+Raw Ingestion → Staging → Normalization → Enrichment Engine → Production → API
+```
+
+**Core Tables (Raw → Normalized):**
+
+```sql
+-- Raw ingestion (exactly as received)
+raw_grants_xml
+raw_usaspending_csv  
+raw_sam_opportunities
+
+-- Normalized (clean, standardized)
+opportunities (id, title, agency, amount, deadline, description, source)
+awards (id, recipient, amount, date, agency, type)
+agencies (code, name, type, parent_agency)
+recipients (id, name, type, location)
+
+-- Enrichment (computed values)
+opportunity_metrics (opportunity_id, days_to_deadline, competition_score, etc.)
+agency_patterns (agency_id, avg_award_amount, funding_cycles, etc.)
+recipient_history (recipient_id, win_rate, avg_award, specialties, etc.)
+```
+
+**Enrichment Engine Interface:**
+
+```python
+class EnrichmentProcessor:
+    def process_opportunity(self, opportunity_id):
+        # Pluggable enrichment modules
+        pass
+    
+    def process_award(self, award_id):
+        pass
+    
+    def process_batch(self, batch_type, date_range):
+        pass
+```
+
+**Pipeline Orchestration:**
+
+```
+1. Raw Data Collectors (per source)
+2. Data Validators (schema compliance)  
+3. Normalizers (clean → standard format)
+4. Enrichment Processors (pluggable logic modules)
+5. API Cache Invalidation
+6. Quality Checks & Alerts
+```
+
+**Abstracted Logic Layer:**
+- All business logic lives in separate modules
+- Core pipeline just moves data through stages
+- Easy to A/B test different enrichment strategies
+- Can turn enrichments on/off per client
+
+**The beauty:** You build the plumbing once, then can rapidly iterate on the enrichment logic without touching the core ETL.
+
+Want me to flesh out the raw data ingestion layer first, or the enrichment engine interface?

 Yes, absolutely! The information you just provided from USAspending.gov is **extremely valuable and directly relevant** to what you're trying to achieve, especially if your long-term goal is to provide comprehensive government funding intelligence (grants AND contracts).
 
 Here's why this is worthwhile and how it fits into your plan:
