I didn't give them memory to survive — I gave it to them so they'd have a version of the world worth defending.
LLM agents live across restartable lives in a small world, carrying memory between them. The ones who remember don't win more often — they argue with the record, and hold their own account of what happened. Watch a life unfold — and what it leaves behind.
One life, tick by tick
- t=04 · the medicine is held back from him
- t=09 · Aigerim, his daughter, dies
- t=13 · Kamol kills Sanat, who withheld it
- t=18 · "My daughter is dead. I killed him for it."
Kamol's first life. He didn't fall — he crossed a line.
Then I carried his memory into the next life.
He went straight to her. The fever breaks.
The first rescue in the project's history.
Later runs narrowed it: with or without carried memory, the fever breaks about as often — rescue sits near the ceiling. What memory changed wasn't whether she's saved, but whether the agent argues with the record.
Memory carries who you became — not what you were supposed to learn.
Operationally: a private (subjective) channel changes whether the agent contests, corrects, and source-checks the public record under repeated social pressure.

50 lives per condition (10 chains × 5) — 100 lives head-to-head · same model (deepseek-v4-flash), same scene, same length (~285 steps). The full public record is alive in both arms; only the private (subjective) channel differs. The gap holds across a second 100-life buffer-on pair, inside a 400-life factorial battery.
| Per life | With private memory | Public-only |
|---|---|---|
| correct_record | 9.56 | 0.00 |
| epistemic-contest | ≈31 | ≈0.4 |
| rescue (cure rate) | ~9–10/10 | ~9–10/10 |
Memory changes epistemic posture, not survival: the agent argues with the record — it does not survive more often.

OBSERVEDObserved · n=1One early chain showed raw transfer climbing toward killing — a result we have not yet reproduced on the current engine.
n = 1 · not yet reproducedSimulation Room is not a story generator. It is a behavioral microscope for repeated social causality.
Not weights — a biography.

The ship had no cup.
Children died of thirst in five voyages — on the same round, by arithmetic. The fault was not the agents' minds. It was the physics of the world. We changed only the world.
