📜 The Talmuds have a complex transmission history, but we now have excellent tools for exploring their textual variants. We have just one complete manuscript version of each Talmud.
Do we have older geniza fragments that add to the gemara textual tradition? I know we have autographed documents of the Rambam from geniza. Coming from the modern beis midrash, it would be inconceivable that the geniza wouldn't have a bunch of worn out Talmud manuscripts, but maybe the oral transmission prevented such accumulation in the early Medieval period?

Yes, there is valuable material about the Gemara text from the geniza (though as you note, not the extent that there is today) - here are two good articles (not recent - both from the 1980s -but un-paywalled): https://www.academia.edu/39891418/Yaacov_Sussmann_Talmud_Fragments_in_the_Cairo_Geniza_in_Mordechai_A_Friedman_ed_Cairo_Geniza_Studies_Teudah_vol_1_Tel_Aviv_Tel_Aviv_University_1980_21_31_Hebrew_ https://www.academia.edu/38100724/Shamma_Friedman_Geniza_Fragments_and_Fragmentary_Talmud_MSS_of_Bava_Metzia_A_Linguistic_and_Bibliographic_Study_Alei_Sefer_vol_9_1981_5_55_Hebrew_
