Because LERA is strongest and most necessary where execution can create serious consequences. If a system only summarizes text or gives low-impact suggestions, the risk may be limited.
But once a system can operate tools, move capital, control infrastructure, affect legal processes, influence physical systems, or trigger irreversible outcomes, execution cannot be treated as ordinary output. LERA was created for precisely this shift.
The higher the consequence of execution, the more necessary LERA becomes.
A system becomes LERA-relevant when its outputs can participate in consequential action.
