In accounts of the Jain canon, who convened the council at Pataliputra to collect and coordinate the surviving scriptures?

Explanation

Sthulabhadra. Scholarly accounts of the Jain canon associate him with convening the Pataliputra council after a famine. The resulting canon was contested by monks associated with the Digambara tradition. Later councils at Mathura and Valabhi complicate a simple “first and second council” sequence.
