# MiroFish: Rehearsing the Future in an AI Social Sandbox

Predicting the future has always been a game of statistics - until now. **MiroFish** introduces a paradigm shift by moving from "predictive modeling" to "social simulation."

## Part 1: Foundations (The Mental Model)

To understand MiroFish, you must stop thinking of AI as a calculator and start thinking of it as a **Digital Sandbox**.

In the real world, events aren't just data points; they are the result of thousands of individual interactions. MiroFish acts as a **Swarm Intelligence Mirror**. It takes seed information (like a news report or a policy draft) and creates a "Mirror World" populated by intelligent agents. 

The mental model is simple: **Don't just calculate the outcome; simulate the players.**

## Part 2: The Investigation

MiroFish isn't just a single model; it's a sophisticated engine that bridges the gap between raw information and social evolution. It stands on two primary pillars:

1.  **High-Fidelity Parallel Worlds**: By extracting entities and relationships from seed materials, it builds a specialized GraphRAG (powered by Zep) that serves as the collective memory of the simulation.
2.  **Autonomous Social Interaction**: Using the **OASIS (Open Agent Social Interaction Simulations)** engine, MiroFish populates its digital sandbox with thousands of agents, each with independent personalities, long-term memory, and behavioral logic.

These agents don't just exist; they interact, form opinions, and undergo social evolution in real-time.

## Part 3: The Diagnosis

For developers and decision-makers, MiroFish solves the "What If" problem by providing a **God's-eye view** of potential futures.

### Deep Dive: How it works for Python Developers

The backend is built with Python, leveraging modern tools like `uv` for lightning-fast dependency management. The workflow is automated:

*   **Graph Building**: Extracts seed info and injects collective memory into a GraphRAG.
*   **Environment Setup**: Generates personas and agent configurations based on the seed data.
*   **Simulation**: Runs dual-platform parallel simulations (e.g., mimicking Twitter or Reddit interactions) using the OASIS engine.
*   **Report Generation**: A dedicated `ReportAgent` analyzes the simulation's results to provide a detailed prediction report.

### Real Use-Cases
*   **Public Opinion Simulation**: "How will the public react to this new policy?"
*   **Creative Sandbox**: "What would happen if the characters in 'Dream of the Red Chamber' made different choices?"
*   **Financial/Political Signals**: Testing the ripple effects of macro-economic signals in a controlled environment.

```python
# A glimpse into how MiroFish manages simulations (simplified)
class SimulationRunner:
    def start_simulation(self, simulation_id: str, platform: str = "parallel"):
        # Initializes the OASIS engine and starts the social sandbox
        process = subprocess.Popen(
            [sys.executable, "run_parallel_simulation.py", "--config", config_path],
            cwd=sim_dir,
            env=env
        )
        # Monitor real-time agent actions...
```

## Part 4: The Resolution

Getting started with MiroFish is straightforward, provided you have the right keys (OpenAI-compatible API and Zep).

1.  **Clone the Repo**: `git clone https://github.com/666ghj/MiroFish`.
2.  **Setup Environment**: Configure your `.env` with `LLM_API_KEY` and `ZEP_API_KEY`.
3.  **One-Click Install**: Run `npm run setup:all` to install frontend and backend dependencies.
4.  **Launch the World**: Use `npm run dev` to start both services and access the dashboard at `localhost:3000`.

## Final Mental Model

**MiroFish = Seed Materials + Multi-Agent Personas + Social Evolution.**

It is a rehearsal laboratory where policies, public relations, and creative ideas can be tested at zero risk. By letting every "what if" see its outcome in a digital mirror, MiroFish makes it possible to predict anything by simply watching it happen.
