Override Mechanism

The override signal must operate on a non-negotiable, hardware-level interrupt that bypasses the AI's software stack. It cannot be queued, buffered, or subject to the model's current inference cycle.

• Preemption: Immediately halts the current cognitive process, not just the physical actuation.
• Atomicity: The cancel command is indivisible; there is no intermediate state where the system partially executes the override.
• Example: A physical emergency-stop circuit that cuts power to actuators independently of the main compute bus.

The human operator's override command must occupy the highest privilege level in the system's control architecture. No autonomous agent, sub-routine, or self-preservation logic can reject, delay, or veto the override.

• Root Access: The override is logically equivalent to a kernel-level signal, not an application request.
• No AI Veto: The model cannot be programmed to argue against or ignore the shutdown command.
• Example: A drone's flight controller where the 'Return-to-Home' failsafe has priority over all navigation objectives.

Upon activation, the system must transition to a defined, safe state without causing catastrophic failure. This is distinct from a 'kill switch' which may simply cut power.

• Safe Fallback: Executes a pre-computed minimal-risk trajectory (e.g., hover, slow stop, safe-mode loop).
• State Persistence: Logs the exact system state vector at the moment of override for forensic analysis.
• Example: An autonomous vehicle that safely pulls over to the shoulder and engages hazard lights rather than slamming on brakes in traffic.

The communication channel for the override must be physically or logically separate from the primary AI control loop to prevent a single point of failure from disabling both.

• Side-Channel: Uses a dedicated frequency, wired circuit, or separate network VLAN.
• No Shared Fate: A denial-of-service attack on the main AI API must not affect the override channel.
• Example: A submarine ROV using an acoustic dead-man switch independent of the fiber-optic tether.

Once triggered, the override state should require a deliberate, multi-step human re-engagement sequence to release. It must not automatically reset when the triggering condition clears.

• Latching Logic: Prevents the system from oscillating between autonomous and manual modes.
• Manual Reset: Requires a physical or cryptographic human confirmation to re-enable autonomy.
• Example: An industrial robot arm that requires a key-turn and a button press in a specific sequence to restart after a safety curtain breach.

The override should not just stop the AI, but transfer situational awareness to the human operator. The operator needs immediate visibility into what the AI was doing and why.

• State Snapshot: Displays the AI's current goal, confidence level, and recent sensor data.
• Deconfliction: Highlights any discrepancy between the AI's world model and raw sensor feeds.
• Example: A trading algorithm override that instantly populates a dashboard showing open positions, pending orders, and the specific risk limit that was breached.
