For the first time, people without the Sharingan were present together in the Uchiha Stone Tablet's secret chamber.
They could not see the deeper layers of the inscription.
But they could witness whether the stone's surface had been moved, inscribed, or replaced.
Fugaku divided the verification authority into four levels.
The clan's recorders were responsible for the text visible to the naked eye.
Two clan members with ordinary Sharingan would separately read the changes in the first layer, without communicating beforehand.
Shisui and Itachi were responsible for recording the deeper layers revealed by their Eye Power.
The Hyuga jonin, the Sealing Squad from the Hokage's Direct Subordinates, and the Land of Rivers Witness would only observe the physical tablet, chakra flows, and those entering and leaving.
No party could determine the final text alone.
Before entering, each reader also had to note the condition of their Eye Power, their hours of sleep, and any recent exposure to genjutsu in their medical record.
After each reading, the Hyuga jonin would check their chakra pathways again.
If abnormal chakra appeared between the two examinations, use of that written record had to be suspended.
Shisui and Itachi were not allowed to activate their eyes at the same time, either.
While one read, the other would remain in an isolation room and could enter only after his own results had been sealed.
This prevented anyone who saw his companion's reaction first from unconsciously reading the same meaning into the text.
