# IIAB-oA Controller

**IIAB-oA Controller** is a specialized infrastructure component for the **Internet-in-a-Box (IIAB)** ecosystem on Android. It acts as a "Walled Garden" and persistent "Watchdog" designed to keep the Termux environment alive and accessible, even on devices with aggressive power management (e.g., Oppo/ColorOS, MIUI).

## Core Capabilities

### 🛡️ Master Watchdog (Supervision Layer)
An independent foreground service dedicated to environment stability:

*   **CPU & Wi-Fi Shield**: Prevents the system from putting Termux into Doze mode or disabling the Wi-Fi radio.
*   **Heartbeat Pulse**: Sends a regulated API signal every 20 seconds to maintain process priority.
*   **Zero-Config Protection**: Works independently of the VPN tunnel.

### 🌐 Safe Pocket Web (Network Layer)
A high-performance VPN tunnel based on the tun2socks engine:

*   **Friendly URLs**: Routes traffic through internal IIAB services seamlessly.
*   **Walled Garden**: Ensures a secure, filtered browsing environment.
*   **Per-App Routing**: Granular control over which applications use the secure tunnel.

### 🔒 Built-in Security
*   **Biometric/PIN Lock**: Authentication is strictly required before the Watchdog or VPN can be disabled.
*   **Safety Check**: Prevents activation if the device lacks a secure lock method (PIN/Pattern/Fingerprint), ensuring the user is never "locked out" of their own settings.
