After an agent indicates a conflict, it is that same agent's responsibility to figure out whether there is actually a conflict or not. Suppose there is a 0.01% difference in the values proposed for the value entity of a parameter by two different selectors. Unless that value is extremely sensitive, this small difference does not constitute a conflict. So the indication of a conflict does not necessarily mean that there is actually a conflict.
Conflict detection is a knowledge based task and it is not always trivial. How detection works in the SiFA paradigm depends on whether the conflict is a criticism conflict or an incompatibility conflict.
