Safety & Redundancy / Human Factors, Supervision & Service Safety
HFE • PHASE 4 SAFETY
Human Factors, Supervision & Service Safety
Operator controls, alerts, permissions, maintenance workflows and residential safeguards designed for understandable and predictable behavior.
Maturity Architecture / verification required
Public-safe scope: this page defines safety architecture and engineering intent. It does not publish implementation thresholds, beam parameters, bypass logic, security credentials, or construction details.
Safety role
Automation reduces repetitive labor but does not remove the need for clear human authority, service discipline and understandable fault behavior.
Required controls
- Unambiguous status indication for autonomous, inhibited, faulted, charging and service states.
- Accessible emergency stop and pause controls appropriate to product scale.
- Residential supervision modes for children, pets and shared outdoor spaces.
- Maintenance procedures that require hazardous-energy isolation before access.
- Alerts that communicate what happened, what was inhibited and what action is required without exposing proprietary internals.
