UST Safety Architecture • Phase 3

Safety functions are non-bypassable

Adaptive or AI optimization sits above deterministic safety logic. A learned profile never overrides hard acoustic, thermal, occupancy, access, fluid or airflow constraints.

Occupancy classification

Human-facing products and unoccupied appliances use different permissive logic.

Human / animal detection

STW, STD and STK are inhibited if a human or animal is detected inside.

Emergency stop

Immediate controlled removal of hazardous output.

Door / access

Protected access states inhibit unsafe operation.

Acoustic / impedance

Abnormal resonance, loading, field or generator conditions trigger derating or shutdown.

Thermal

Monitor user and hardware temperatures as applicable.

Fluid / leak

Prevent dry-fire, overflow, leaks and invalid coupling states.

Airflow / humidity

Dependent operating states require verified extraction / environment.

Sensor disagreement

Critical disagreement forces safe degradation or shutdown.

Experimental / advanced sensors

Any future quantum, research-grade, calibration or advanced sensing subsystem receives its own compatibility and safety validation. If a mode is not explicitly validated for people or animals, occupancy logic inhibits that mode.
