Silencing the panel is mistaken for restoration

A fictional controller displays a detector alarm followed by a communication fault. A supplied instruction distinguishes local buzzer silence from field notification and reset. An operator silences the buzzer and signs the handover as fully normal, although the device cause, missing communication and linked-output feedback have not been investigated. A colleague assumes a command log proves every fan and door physically responded. No real controller is operated or reset in this exercise. Identify the states and evidence that remain unresolved, explain the difference between acknowledgement and restoration and describe why the actual authorized impairment and escalation process is needed rather than hiding the indication.
