survivable

This term describes a threshold of endurance where a catastrophic event or a hostile environment does not lead to total destruction. It carries a clinical or technical tone, often appearing in safety reports, engineering assessments, or biological studies to determine the limit of what a human or system can withstand.

While similar to "bearable" or "tolerable," it specifically implies a binary outcome between life and death or operational success and total failure. It focuses on the possibility of persistence rather than the comfort of the experience.
