With the issuance of Order 66, 99% of the Jedi have died out. The surviving Obi-Wan and Yoda go to the Jedi Temple and change the message to "Return to the Jedi Temple because the war is over. The other surviving Jedi were caught in a trap and killed by the clone soldiers, for fear that they would be killed. Then they learn from the holocamera that Anakin has betrayed many Jedi and was praised by the Emperor. Yoda and Obi-Wan believed that the emperor would seize the entire Jedi heritage through Anakin, who became one of his council members. This includes archival books, holocrons, data maps, and surveillance cams. To stop this, Yoda challenged the Emperor and Obi-Wan challenged Vader to a fight. However, Yoda also had an idea for what would happen if the assassination failed. He tries to hide out on a remote planet far from Coruscant. He doesn't want the Empire to know about the planet's existence, so he erases the coordinates of the planet Dagobah from the Cathedral's holomap. Just as the disciples once erased information about the Camino.
As a result, the assassination fails and Yoda escapes to Dagobah. Only Obi Wan and Organa know about it.
Meanwhile, the emperor has seized everything: the Jedi heritage, political power, military might, and new apprenticeships. He uses all the evidence he can to convince the public of the "Jedi conspiracy" through bureaucratic explanations. This is where the recording files in the office and the surveillance cams of the Jedi Temple came in handy.
During the war, the few remaining Jedi in the temple and the surveillance cams of the council are viewed by the Emperor himself, using Vader. As expected by the Emperor, 99% of the Jedi confirm that the Jedi were desperate to bring the war to a quick end. The process will be sussed out from operational and communication records.
It turns out that the senators in the Senate had handed over their authority to the chancellor, in some cases at the advice of their friend the Jedi! When the Emperor learned of this from the correspondence records, he presented it to the bureaucrats as evidence of the Jedi's strong desire for centralization. Perhaps, when the council did not detect it, the Jedi, weary of the protracted war, wanted the Senate to act immediately, saving them the trouble of discussion.
To the surprise of even the emperor, it was the Jedi who had a senator present a bill that would make the chancellor the supreme commander and place the council under his supervision. The Emperor had expected that the Council members did not like the bill and were wary of the Chancellor manipulating the army without the interference of the Senate. But he did not expect that the initiator of the bill was a Jedi. The Jedi may have thought that in a successful coup d'état, in which the council members would arrest the supreme chancellor, the council would take over all the powers that the chancellor had. Then, naturally, the Council would have the power to control the army without the interference of the Senate. To prove this, the emperor would submit to the bureaucracy about the existence of its Jedi. Perhaps it was the Jedi of the 1% who were happy to see the Chancellor's power strengthened by the prolonged war.
The emperor will have the vaders and bureaucrats check the military database against the chancellor's database to see if there are any planets where Order 66 has not been carried out and if there are any surviving Jedi. Then have Vader erase the surveillance footage of Anakin killing the Jedi.
He does this in order to mislead the public into thinking that Skywalker (the Chosen One) also died in Order 66. Vader's identity cannot be exposed.
