Overview

Requirements define what the system should do. They are:

• Traceable - Each requirement has a unique ID

• Testable - Can be verified through testing

• Clear - Unambiguous and specific

• Linked - Connected to design and implementation

Requirement Hierarchy

Requirements are organized in two levels:

1. System Requirements (REQ_SYS_*) - High-level system capabilities

2. Component Requirements - Detailed component-level specifications

   • REQ_WEB_* - Web server and user interface

   • REQ_CFG_JSON_* - Configuration management (JSON-based system)

   • REQ_NETIF_TUNNEL_* - QEMU network tunnel driver

Component requirements are linked to their parent system requirements using Sphinx-Needs :links: attribute.

All requirements use Sphinx-Needs directives for automatic traceability and validation.
