# Integration Guide

## Critical Fixes Applied

### 1. ✅ app.py - Entry Point Added
**Fixed**: Added `if __name__ == "__main__"` block to launch the Gradio interface
```python
if __name__ == "__main__":
    demo = create_mobile_optimized_interface()
    demo.launch(server_name="0.0.0.0", server_port=7860, share=False)
```

### 2. ✅ agent_stubs.py - Created
**Created**: Stub agent implementations for orchestrator dependencies
- `IntentRecognitionAgent`
- `ResponseSynthesisAgent`  
- `SafetyCheckAgent`

## Remaining Integration Tasks

### Priority 1: Connect Components
Create `main.py` to integrate all components:

```python
# main.py structure needed:

import gradio as gr
from app import create_mobile_optimized_interface
from llm_router import LLMRouter
from orchestrator_engine import MVPOrchestrator
from context_manager import EfficientContextManager
from agent_stubs import *
from config import settings

# Initialize components
llm_router = LLMRouter(settings.hf_token)
context_manager = EfficientContextManager()
agents = {
    'intent_recognition': IntentRecognitionAgent(llm_router),
    'response_synthesis': ResponseSynthesisAgent(),
    'safety_check': SafetyCheckAgent()
}

orchestrator = MVPOrchestrator(llm_router, context_manager, agents)

# Create and launch app
demo = create_mobile_optimized_interface()
demo.launch()
```

### Priority 2: Implement TODOs
Files with TODO markers that need implementation:

1. **llm_router.py**
   - Line 45: `_call_hf_endpoint()` - Implement actual HF API calls
   - Line 35: `_is_model_healthy()` - Implement health checks
   - Line 38: `_get_fallback_model()` - Implement fallback logic

2. **context_manager.py**
   - Line 47: `_get_from_memory_cache()` - Implement cache retrieval
   - Line 54: `_retrieve_from_db()` - Implement database access
   - Line 73: `_update_context()` - Implement context updates
   - Line 81: `_extract_entities()` - Implement NER
   - Line 87: `_generate_summary()` - Implement summarization

3. **agent_stubs.py**
   - All `execute()` methods are stubs - need full implementation
   - Intent recognition logic
   - Response synthesis logic  
   - Safety checking logic

4. **mobile_events.py**
   - Line 17-37: Event bindings commented out
   - Need proper integration with app.py

### Priority 3: Missing Implementations

#### Database Operations
- No SQLite connection handling
- No FAISS index initialization in context_manager
- No session persistence

#### LLM Endpoint Calls  
- No actual API calls to Hugging Face
- No error handling for API failures
- No token management

#### Agent Logic
- Intent recognition is placeholder
- Response synthesis not implemented
- Safety checking not implemented

## Safe Execution Path

To test the framework without errors:

### Minimal Working Setup
1. ✅ Create simplified `main.py` that:
   - Initializes only UI (app.py)
   - Skips orchestrator (returns mock responses)
   - Tests mobile interface rendering

2. ✅ Comment out orchestrator dependencies in app.py
3. ✅ Add mock response handler for testing

### Incremental Integration
1. **Phase 1**: UI Only - Launch Gradio interface
2. **Phase 2**: Add Context Manager - Test caching
3. **Phase 3**: Add LLM Router - Test model routing
4. **Phase 4**: Add Orchestrator - Test full flow

## Development Checklist

- [ ] Create `main.py` integration file
- [ ] Implement HF API calls in llm_router.py
- [ ] Implement database access in context_manager.py
- [ ] Implement agent logic in agent_stubs.py
- [ ] Add error handling throughout
- [ ] Add logging configuration
- [ ] Connect mobile_events.py properly
- [ ] Test each component independently
- [ ] Test integrated system
- [ ] Add unit tests
- [ ] Add integration tests

## Known Limitations

1. **Mock Data**: Currently returns placeholder data
2. **No Persistence**: Sessions not saved to database
3. **No LLM Calls**: No actual model inference
4. **No Safety**: Content moderation not functional
5. **Event Handlers**: Not connected to app.py

## Next Steps

1. Start with `app.py` - ensure it launches
2. Add simple mock handler for testing
3. Implement database layer
4. Add HF API integration
5. Implement agent logic
6. Add error handling and logging
7. Test end-to-end
