This drone and the "kid", who disassembled other drones into important details, were killed by the same "dinosaurs", so it is unlikely that the core V (If it remains intact) will be in the oven where there were other cores in banks, most likely the absolute solver will activate the same program for collecting materials, but it can maybe she will be able to rebuild herself, so I don't think she died forever, although, as J said: "... - Utility models always have copies...", I think that V will return as a copy, with the same memories, even probably with those memories where she died
i kinda expected J to have a mental breakdown when seeing V's dead corpse, (i just remembered that murder drones have that meat thingy in them, and can revive themselves if the consume enough matter, so that's a theory that V might come back)
