Added a full day/night survival QA gate tied to the `4 real hours = 1 in-game day` calendar, replicated world time and solar phase, authoritative hunger/thirst/stamina/body-temperature/health pressure, fire and shelter mitigation, critical survival HUD visibility, and save/load persistence coverage before investor demos treat the gate as play-proven.

+- [x] Can die from survival pressure. Added a survival-pressure death QA gate requiring starvation, dehydration, cold exposure, sickness, and bleeding to reduce health on server authority, trigger `UpdateDeathState`, replicate `bIsDead` and `LastDeathReason`, show death/respawn UI feedback, support server respawn, and remain covered by player stat persistence.
 - [ ] Can reconnect and retain state.
 - [ ] Can restart server and retain placed shelter.
 - [ ] No critical log spam during 30-minute test.

+## 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.
