# ArduPilot Custom Firmware Builder (EqualMass Edition)

## 🛠EqualMass Customization Layer (Added Feb 2026)

This repository has been customized to support a persistent, automated **Patch Management System**. These modifications allow for custom source code injection and regional data integration while maintaining a production-grade infrastructure on Debian 13.

### 📁 Modified & New Files
* **`docker-compose.yml`**: Updated to include the `overlay-manager` sidecar service and shared volumes for persistent code injection.
* **`builder/builder.py`**: Modified to detect custom source files in the `/srv` directory. The engine now automatically merges these overlays into the ArduPilot source tree before the Waf compiler begins the build.
* **`web/templates/index.html`**: The main dashboard now features a stylized "Patch Manager" bridge button in the navigation bar to allow seamless switching between the builder and the sidecar.
* **`overlay_manager/` (New Service)**: 
    * `main.py`: A FastAPI-based engine designed to manage (Upload/Edit/Delete) custom source files within the Docker environment.
    * `templates/index.html`: A custom UI for managing patches, matching the ArduPilot ecosystem aesthetic.
    * `static/logo.png`: Localized branding assets for the sidecar interface.

### 🌐 Network & Routing Architecture
The system is unified behind an **Nginx Reverse Proxy** to provide a professional, single-domain experience:
* **Main Builder UI**: `https://ardupilot.equalmass.com/` (Proxied to port `11080`).
* **Patch Manager**: `https://ardupilot.equalmass.com/patch-manager/` (Proxied to port `11081`).
* **SSL Termination**: Managed via Nginx for the `equalmass.com` domain.
