I'd write that first section differently to allow for the fact that The Eight Doctors doesn't explicitly say the Daleks put him on trial and killed him immediately after his arrival. Something like:

According to one account the Master was driven insane by his experience on the Cheetah Planet. Seeking revenge on the Doctor, he hatched a scheme to leave his corrupted body for the Doctor's own, which would also grant him the Doctor's remaining regenerations. He acquired a Deathworm Morphant and made his way to Skaro, where he intended to goad the Daleks into executing him. (PROSE: The Eight Doctors)

Although another account does state that an incarnation of the Master was put on trial by the Daleks on Skaro and executed, subsequently escaping in the form of the Deathworm Morphant, (TV: Doctor Who, PROSE: The Novel of the Film) many show that the Trakenite Master's adventures continued for a long time after his experience on the Cheetah World before his body was killed by the Daleks.
