Rav Yose

Rav Yose is usually counted among the earliest Savoraim, right after the end of the Amoraic period. He belongs to the generation after the main discussions of the Babylonian Talmud had already been completed, but before the text reached its final organized form.

For your timeline, Rav Yose represents the beginning of the post-Amoraic editing stage. His period marks the moment when the sages were no longer mainly creating new Talmudic debates, but were helping arrange, explain, and preserve the discussions of earlier Amoraim.
