Is there a specific line below where the person at the end stops being yourself in a way that matters internally or externally?

A. you go to sleep and wake up in the morning

B. You lose all cognition in a coma then wake up from it.

C. A teleporter like Star trek reconstitutes your body seamlessly in another location without you losing consciousness during the process.

D. The same teleporter stores the state of your body and brain as static data for a few seconds before finishing the teleport, but you don't notice it.

E. The same process as D, except that the original copy of your body is not absorbed as part of the process, resulting in 2 of you existing.

Finally for E, does this demonstrate that the process of D is effectively killing the original , and should the technician then be tried for murder?
