  │ Assertions: Result set correctness
  │ Time: <300ms
  └─ Result: Query correctness

// Graph Consistency (Critical)
test_graph_consistency_validation    [consistency]
  │ Coverage: Cycle detection in RDF
  │ Assertions: Cycle identification
  │ Time: <200ms
  └─ Result: Cycle detection correctness
```

**Why These Tests:**
- ✅ RDF is semantic foundation (correctness critical)
- ✅ Ontology defines all relationships
- ✅ SPARQL enables search & reasoning
- ✅ Consistency prevents data corruption
