+## Survival Pressure Death
+
+The survival-pressure death gate proves the MVP does not merely display hunger,
+thirst, exposure, illness, or injury as cosmetic stats. Sustained pressure must
+be able to reduce health, mark the character dead, replicate the death state,
+and expose a clear respawn path.
+
+Required evidence:
+
+- Starvation, dehydration, cold exposure, sickness, and bleeding can reduce
+  `Survival.Health` on server authority.
+- `ClampSurvival` calls `UpdateDeathState`, clamps health to zero, clears
+  stamina, sets `bIsDead`, and records `LastDeathReason`.
+- The replicated survival snapshot includes the death state and last death
+  reason.
+- The critical survival HUD and death/respawn panel display the dead state and
+  cause.
+- The player controller exposes the MVP respawn path and revives the survival
+  component on the server.
+- Death/respawn behavior remains persistence-safe through the player stat
+  save/load path.
+
+This gate is gameplay/server-relevant and should be covered by the next server
+package deployment.
