Bare-metal Rust on the Cortex-R5F. Sub-1ms O(1) reflex check. Hardware-tied eFUSE DNA licensing. The mathematical safety floor your AI stack cannot override.
The Problem
Autonomous systems running AI make probabilistic decisions. Every inference, every control output, every safety evaluation carries a confidence score rather than a mathematical proof. That is not a flaw in AI design -- it is a fundamental property of learned models. But it creates a structural problem when you build a safety layer on the same probabilistic stack.
When the AI is wrong, the software safety layer is wrong with it. Both layers share the same model weights, the same training distribution, the same failure modes. A safety layer that operates inside the AI stack does not provide independent verification -- it provides correlated confirmation. In the worst-case scenario, the scenario where you most need the safety layer to catch the AI, the AI and the safety layer fail together.
The architectural argument is straightforward: safety must be mathematically separate from the system it supervises. A safety system that depends on the correctness of the system it is protecting is not a safety system. It is a mirror.
The AetheriDrive DSK solves this by operating below the AI stack entirely, at the MPU level, with a formally-proven rule set that the AI cannot modify, cannot bypass, and cannot influence. It does not ask the AI whether a command is safe. It checks the command against a pre-proven constraint set and either passes it or severs it -- in constant time, with no probabilistic element.
Architecture
The DSK sits between the AI control output and the robot's actuators at the MPU level. On every command cycle, it performs an O(1) sub-1ms reflex check against a pre-proven safety rule set. Any command that violates a rule is physically severed before it reaches the motor. No exceptions. No retries. No fallback to a probabilistic override.
The safety check runs on the ARM Cortex-R5F RPU in bare-metal Rust -- no operating system, no runtime, no scheduler that can be preempted. Execution time is bounded by construction, not by profiling. The worst-case execution time (WCET) is deterministic because the code path is deterministic.
Licensing is hardware-tied via eFUSE DNA. The license binary is cryptographically bound to the physical silicon identity of the deployment target using air-gapped Ed25519 signing. The binary cannot execute on unauthorized hardware, cannot be cloned, and cannot be moved to a different unit without a new license issuance. Your IP stays yours. Our safety stays locked.
The C-ABI interface exposes exactly two entry points: aetheridos_safety_update() and aetheridos_submit_command(). There is no ROS dependency in the safety path. The DSK operates below any middleware layer and does not require ROS, ROS 2, or any robotics framework to function.
Technical Specifications
Required Precursor
Before deploying the DSK, the Reflex Gap on your production hardware must be measured. The Reflex Gap is the interval between AI decision output and confirmed machine response at the actuation layer -- a number that software-layer benchmarks cannot see, and that the DSK enforcement boundaries must be calibrated against.
The AetheriDrive Latency Lab uses optically isolated interceptors on CAN FD or EtherCAT to measure the Reflex Gap at the signal level. The measurement cannot be fabricated or obscured by the AI stack or motor firmware. The result is a ground-truth baseline and a formal ROI report documenting the latency tax the OEM is currently carrying.
10-day turnaround. Fixed-price audit. Fully remote. The deliverable satisfies ISO 26262, IEC 61508, EU AI Act, and TRAIGA documentation requirements for physical response time evidence.
