Consistency policies

Consistency policies determine whether the combination of observing states reported by multiple subsystems represents a safe and meaningful system condition.

They are primarily used during critical operational phases, such as active scanning, where temporary inconsistencies or missing subsystems may indicate degraded behavior or fault conditions.

A policy evaluation produces a decision describing:

• the target observing state to be applied,

• whether a consistency fault should be raised,

• whether state publication should bypass debounce delays.

• Base observation consistency policy
• Scan consistency policy
• Scheduled scan policy
• Decision model
• Evaluation outcome
