The central claim of Biostasis is that identity survives if information survives. But you can't just assert this and move on. You need to grapple with what identity actually is at the physical level, then check a particular preservation technique can plausibly maintain those structures. This topic exists to bridge the gap between "freezing might work in principle" and "here's the actual chemistry and biology that makes it credible." The goal is to transform cryopreservation from a thought experiment into something with real mechanistic grounding.
