How does an arahant know that ignorance won't return/re-arise after death?

The earlier aspects that now seem less relevant imo: > *---How can it be known that ignorance won't return/re-arise and why won't it return/re-arise if there is no consciousness after death? > ---From what I remember seeing according to the linear view of the links of dependent origination ignorance is the cause of fabrications > and fabrications are the cause of consciousness. > ---It seems to me that consciousness is required for this type of knowledge, so when an arahant dies how can there be knowing and thus > certainty that ignorance won't reform/re-arise after death if there > isn't even consciousness?* **The aspects below that I currently think are more relevant:** Is it considered as being abhiññā i.e "direct knowledge" that occurs before the arahant dies? How does one know that this abhiññā is completely true? It seems to me that omniscience is required. "Logically-speaking" doesn't truly knowing something like that require omniscience to verify that one isn't deceiving oneself?
