## Integration Points

### Component Integration Matrix

| Component | Integrates With | Interface | Data Format |
|-----------|----------------|-----------|-------------|
| Semantic Parser | NL Mapper | Python API | SemanticGraph |
| NL Mapper | IR, Circuit Library | Python API | GateMapping |
| Circuit Library | Optimizer, Cache | Python API | CircuitTemplate |
| Optimizer | Compiler | Python API | QuantumCircuit |
| Compiler | Quantum Connector | Python API | Backend Circuit |
| Profiler | quantum(), Dashboard | Context Manager | ProfilerData |
| Batcher | quantum() | Python API | JobBatch |
| Cache | quantum(), Compiler | Python API | CacheEntry |
| Dashboard | Profiler | Python API | HTML String |
| Billing | quantum(), Profiler | Python API | CostMetrics |

### Critical Integration Points

#### 1. quantum() ↔ Profiler
```python
# Integration via decorator or explicit call
result, metrics = profiler.profile_quantum(
    program="...",
    shots=1000
)
```

#### 2. NL Mapper ↔ Circuit Library
```python
# Mapper checks library for templates
mapping = mapper.map_to_gates(query)
templates = catalog.search(query)
if templates and templates[0].confidence > 0.8:
    use_template(templates[0])
```

#### 3. Circuit ↔ Cache
```python
# Automatic caching in quantum()
cache_key = CacheKey.from_ir(ir_program, backend, opt_level)
cached = cache.get(cache_key)
if cached:
    return cached
# ... execute ...
cache.set(cache_key, result)
```

#### 4. Profiler ↔ Dashboard
```python
# Dashboard consumes profiler data
profiler_data = profiler.get_summary()
html = dashboard.generate_html(profiler_data)
```
