# Concept: Architecture (The Trinity ΔΩΨ)

arifOS is built upon the **Trinity Architecture**, a three-layered governance model designed to ensure that AI agents operate within human-defined ethical, physical, and logical bounds.

## 🏛️ The Three Pillars (ΔΩΨ)

1.  **Δ Mind (AGI - Intelligence)**: Logic, reasoning, and multi-source synthesis. Focuses on clarity, uncertainty quantification, and hallucination prevention.
2.  **Ω Heart (ASI - Safety)**: Ethical critique, consequence simulation, and empathy. Acts as the adversarial layer to the Mind.
3.  **Ψ Soul (APEX - Governance)**: Sovereign judgment, final verification, and immutable auditing. Houses the Constitutional Kernel (CCC).

## 🛠️ The 11-Tool Sovereign Surface

The material interface of arifOS is the **11-Tool Canonical Surface**. These tools are mapped to execution stages (000-999) and the Trinity layers.

| # | Canonical Alias | Stage | Trinity | Layer |
| :--- | :--- | :--- | :--- | :--- |
| **1** | `arifos_init` | 000 | Ψ | GOVERNANCE |
| **2** | `arifos_sense` | 111 | Δ | MACHINE |
| **3** | `arifos_mind` | 333 | Δ | INTELLIGENCE |
| **4** | `arifos_kernel` | 444_KERNEL | Δ/Ψ | GOVERNANCE |
| **5** | `arifos_memory` | 555 | Ω | INTELLIGENCE |
| **6** | `arifos_heart` | 666 | Ω | INTELLIGENCE |
| **7** | `arifos_ops` | 777 | Δ | MACHINE |
| **8** | `arifos_judge` | 888 | Ψ | GOVERNANCE |
| **9** | `arifos_vault` | 999 | Ψ | GOVERNANCE |
| **10** | `arifos_forge` | 010 | Δ | EXECUTION |
| **11** | `arifos_vps_monitor` | 111 | Δ | MACHINE |

> [!NOTE]
> `arifos_route` is deprecated — use `arifos_kernel` (444_KERNEL) instead.

## 🌉 The Archi-Bridge (AAA/BBB/CCC)

The system enforces a physical and logical separation between the user-facing interface and the governing kernel.

-   **AAA (Application Layer)**: Mutable, user-facing interfaces (CLI, Web, MCP).
-   **BBB (Protocol Bridge)**: The audited channel through which intent travels.
-   **CCC (Constitutional Kernel)**: The immutable, rule-enforcing Metabolic Core.

> [!IMPORTANT]
> **Separation of Powers**: Tools like `arifos_forge` are strictly execution-only and require a **SEAL** verdict from `arifos_judge` to operate. This ensures that the kernel evaluates *risk* before the machine performs *work*.
