Authority-Governed Assured Autonomy Rover Testbed: System Architecture, Governance Design, and Reproducible Artifact Package

This record contains a technical report and fully reproducible artifact package for the "Authority-Governed Assured Autonomy Rover Testbed," a research platform designed for autonomous systems operating under degraded and adversarial conditions.

The testbed integrates three governance architectures:

• SATA (Sensor Trust Assessment)
• HMAA (Hierarchical Multi-Level Authority Allocation)
• CARA (Context-Aware Recovery Architecture)

These components form a unified pipeline for trust-aware decision-making, authority computation, and adaptive recovery under uncertainty and attack scenarios.

The artifact package includes:

• Full system architecture and formal methodology (paper)
• Interactive governance simulator with fault injection scenarios
• Complete hardware design (blueprint, schematic, BOM)
• Electrical connection graph (76 connections with pins and voltages)
• System configuration (component-level specification)
• Assembly guide for physical platform construction
• Source repository (Python implementation, formal models, CI pipeline)

Validation status (v1.0):

• Technology Readiness Level (TRL): 3–4
• Governance architectures validated via simulation (350 structured runs across 7 fault-injection scenarios)
• Hardware design and build artifacts are complete
• Physical assembly is in progress
• Hardware experimental validation will be included in v2.0

This artifact is intended for reproducibility, system design inspection, and simulation-based validation. It does not represent a fully hardware-validated system at this stage.
