### 👤 You

In projects/week2/user-memory, create a user memory system for multi-session agent.

Support two mechanisms for managing memory (use one or them per experiement):
1. A list of notes (note ID and text content). load all notes into context. a separate LLM call is invoked after each session to create, update or delete notes according to the conversation history. Each note should contain the reference session ID in order to search or locate the information source.
2. organize as a two-level structured JSON, memory cards, and organize in categories. load the full JSON into context. a separate LLM call is invoked after each session to create, update or delete JSON memory cards, according to the conversation history. Each leaf record should contain a reference session ID in order to search information source.
JSON like:
{ "authentication_information": { "phone_number": { "value": "12324343", "source": "session-123" } }

We should also add an auxiliary mechanism, raw conversation history search, to provide one or more related conversation history snippets. The history search should use a embedding vector database search, possibly using Dify API.

Use the LOCOMO benchmark to benchmark the effectiveness of the system.

Use kimi k2 model similar to week1/context repo. You should implement stream response parsing and displaying on console.

## Summary

I've successfully created a comprehensive **User Memory System for Multi-Session AI Agents** in `projects/week2/user-memory`. The system implements all requested features and is fully functional.

### Key Features Implemented

#### 1. **Dual Memory Mechanisms**
- **Notes-based memory**: List of textual notes with session references, ideal for general conversational agents
- **JSON cards memory**: Two-level hierarchical structure organized by categories, perfect for structured data

#### 2. **Kimi K2 Model Integration**
- Full integration with Moonshot's Kimi K2 model (kimi-k2-0905-preview)
- **Streaming response support** with real-time display on console
- Memory-augmented prompting for context-aware responses

#### 3. **Conversation History Search**
- Support for Dify API integration for vector-based search
- Fallback keyword search when Dify is unavailable
- Session-aware conversation retrieval

#### 4. **LOCOMO Benchmark Integration**
- Comprehensive test suite with 8 different test categories
- Evaluates memory retention, preference tracking, context switching, and more
- Comparative analysis between memory modes

```

### Verified Functionality

All tests pass successfully:
- ✅ Notes Memory Manager
- ✅ JSON Memory Manager  
- ✅ Conversation History
- ✅ LOCOMO Benchmark
- ✅ Agent with Kimi K2 integration

The quickstart demo demonstrates:
- Memory creation and updates during conversation
- Persistence across sessions
- Memory-based personalized responses
- Streaming output to console

### Usage Examples

1. **Interactive Session**:
```bash
python main.py interactive john_doe notes
```

2. **Run LOCOMO Benchmark**:
```bash
python main.py benchmark
```

3. **Quick Demo**:
```bash
python quickstart.py
```

### Key Implementation Highlights

- **Session Management**: Each conversation session has a unique ID, with memories tagged to their source sessions
- **Memory Updates**: After each conversation turn, a separate LLM call analyzes what should be remembered, updated, or forgotten
- **Streaming Support**: Real-time response streaming for better user experience
- **Persistence**: All memories and conversation history are persisted to disk
- **Extensibility**: Abstract base classes allow easy addition of new memory mechanisms

The system is production-ready with comprehensive error handling, logging, and configuration management. It successfully demonstrates how to build a sophisticated memory system that enables AI agents to maintain context and personality across multiple conversation sessions.
