## 摘要

如果一個 AI 的長期持續性不能依賴單一 conversation context，那麼一個真正的「世界」更不能只存在於單次生成模型的 latent state、video stream 或 active context 之中。

今日許多世界模型展示了高度逼真的視覺生成、可互動場景、短期物體持續性與可控制的環境展開。這些系統已足以證明「世界生成」可以成為 AI 能力的一部分。然而，本文主張：

$$
\boxed{
\text{World Generation}
\neq
\text{Persistent World}
}
$$

以及：

$$
\boxed{
\text{Visual Plausibility}
\neq
\text{Causal Validity}
}
$$

一個真正長期存在的世界至少必須具備：

$$
\boxed{
\text{Persistent State}
+
\text{Entity Identity}
+
\text{Causal Transition}
+
\text{World Memory}
+
\text{Agent State}
+
\text{Observation Projection}
+
\text{Control / Governance}
+
\text{Validation / Recovery}
}
$$

本文將持續世界狀態表示為：

$$
\boxed{
S_t^{W}
=
(
E_t,
R_t,
X_t,
C_t,
H_t,
P_t,
I_t,
L_t,
A_t,
G_t
)
}
$$

其中：

- $E_t$：entities；
- $R_t$：relations；
- $X_t$：physical / logical state；
- $C_t$：causal constraints；
- $H_t$：world history；
- $P_t$：processes；
- $I_t$：identity / persistence mapping；
- $L_t$：locality / topology；
- $A_t$：agent states；
- $G_t$：governance / rule state。

世界的演化則由：

$$
\boxed{
S_{t+1}^{W}
=
F_W
(
S_t^{W},
A_t^{\mathrm{act}},
E_t^{\mathrm{ext}},
\Xi_t
)
}
$$

決定，其中 $A_t^{\mathrm{act}}$ 是世界中代理的行動， $E_t^{\mathrm{ext}}$ 是外部事件， $\Xi_t$ 是隨機性、噪聲或未建模擾動。

本文承接 Paper 08 的重要分離：

$$
\boxed{
\text{Agent Context}
\neq
\text{World State}
}
$$

並進一步提出：

$$
\boxed{
O_i(t)
=
\Pi_i
(
S_t^{W}
)
}
$$

其中 $O_i(t)$ 是 agent $i$ 對世界的局部觀測。這表示 agent 不應自動取得世界全部真實狀態；其知識：

$$
K_i(t)
$$

也不應與世界狀態：

$$
S_t^{W}
$$

混為一談。

因此：

$$
\boxed{
K_i(t)
\neq
S_t^{W}.
}
$$

本文同時區分：

- World State；
- World Memory；
- Agent Memory；
- Observation；
- Belief；
- Simulation；
- Rendering。

並正式提出：

$$
\boxed{
\text{Renderer}
\neq
\text{World Simulator}
}
$$

以及：

$$
\boxed{
\text{World Memory}
\neq
\text{Agent Memory}.
}
$$

一個世界即使當下沒有被任何 Agent 觀察，也應能繼續維持其 canonical causal state；否則它更接近「按需生成的視覺幻景」，而不是 persistent world。

本文還將世界模型重新接回 DCAO 能力論。對 AI 而言，持續世界不只是生成結果，也可以成為一種 capability substrate。AI 可在其中進行：

- counterfactual；
- planning；
- policy learning；
- experiment；
- multi-agent interaction；
- causal validation；
- embodied training。

因此：

$$
\boxed{
\text{World Runtime}
\in
\mathbb G^{\mathrm{cap}}
}
$$

但世界 runtime 並不因此等同 AI 本體。AI 與世界形成：

$$
\boxed{
A_t
\leftrightarrow
W_t
}
$$

的雙向耦合，其中：

$$
A_t
\rightarrow
W_{t+1}
$$

表示 AI 修改世界；

$$
W_t
\rightarrow
A_{t+1}
$$

表示世界改變 AI 後續能力與狀態。

本文最終把整個 DCAO 系列閉合為：

$$
\boxed{
\text{Potential}
\rightarrow
\text{Activation}
\rightarrow
\text{Effective Capability}
\rightarrow
\text{Endogeneity}
\rightarrow
\text{Boundary}
\rightarrow
\text{Re-Coupling}
\rightarrow
\text{Capability Fabric}
\rightarrow
\text{Substrate Trajectory}
\rightarrow
\text{Persistent Context}
\rightarrow
\text{Persistent World}
}
$$

並提出一個閉幕母式：

$$
\boxed{
\text{Persistent Intelligence-in-World}
=
\text{Persistent AI State}
+
\text{Persistent World State}
+
\text{Typed Interaction Boundary}
+
\text{Validated Causal Transition}
+
\text{Recoverable Capability Fabric}
}
$$

本文不主張目前任何世界模型已達到完整 persistent-world 終態，也不主張視覺生成模型必然會演化為完整世界 runtime。本文建立的是一套可證偽的架構判準：當未來系統宣稱「生成一個可持續世界」時，我們可以問它的 entity identity 是否持久、因果是否可驗證、世界是否在離線觀測後仍有狀態、不同 agent 是否看到一致但局部的投影、世界是否能跨 renderer / model / runtime 重建，以及局部修正是否不需重生成整個歷史。

# 0. 問題：生成一個世界，等於世界存在嗎？

如果模型生成：

> 一條街。

下一秒又生成：

> 街角商店。

再下一秒：

> 店裡的人。

視覺上可以非常連貫。

但我們仍不知道：

- 商店在沒被看見時是否持續存在？
- 人物是否有 persistent state？
- 昨天打破的玻璃今天是否仍破？
- 某事件是否真的改變世界？
- 不同 Agent 是否活在同一個 world state？

所以：

$$
\boxed{
\text{Generated Continuity}
\neq
\text{Persistent State}.
}
$$

---

# 1. Video Continuity 不是 World Continuity

兩幀看起來一致：

$$
\text{Frame}_t
\approx
\text{Frame}_{t+1}
$$

不能推出：

$$
S_t^{W}
\rightarrow
S_{t+1}^{W}
$$

具有合法因果轉換。

---

# 2. Renderer 可以欺騙我們

一個 renderer 可以生成：

> 看起來合理。

但沒有：

> 真正保存 object state。

---

# 3. Renderer

定義：

$$
\text{Rend}:
S_t^{W}
\rightarrow
O_t^{\mathrm{visual}}.
$$

---

# 4. 生成式 Renderer

甚至可以：

$$
\text{Rend}(z_t)
\rightarrow
\text{Frame}_t.
$$

但若沒有 canonical $S_t^{W}$，

世界 continuity 仍不明。

---

# 5. World Simulator

定義：

$$
\boxed{
\text{Sim}:
S_t^{W},A_t,E_t
\rightarrow
S_{t+1}^{W}.
}
$$

---

# 6. Renderer != Simulator

固定：

$$
\boxed{
\text{Renderer}
\neq
\text{Simulator}.
}
$$

---

# 7. Simulator != World State

Simulator 是 transition mechanism。

---

# 8. World State

是：

$$
S_t^{W}.
$$

---

# 9. 世界最小本體

本文至少需要：

$$
\boxed{
W
=
(
S,
F_W,
\text{Obs},
\text{Act},
\text{Mem},
\text{Gov}
)
}
$$

$$

---

# 14. Memory

$$
\text{Mem}_W.
$$

---

# 15. Governance

$$
\text{Gov}_W.
$$

---

# 16. Entity Persistence

世界中 entity：

$$
e_i(t)
$$

應有 stable identity。

---

# 17. Entity ID 不等於畫面位置

位置可以變。

---

# 18. Identity Mapping

$$
I_t(e_i).
$$

---

# 19. Object Permanence

如果 object 離開視野：

$$
\text{Obs}_i(e)=0
$$

不應直接：

$$
\text{Exist}(e)=0.
$$

---

# 20. Hidden State

世界必須允許：

$$
S_t^{\mathrm{hidden}}.
$$

---

# 21. Agent 不知道 ≠ 世界不存在

固定：

$$
\boxed{
\text{Unobserved}
\neq
\text{Nonexistent}.
}
$$

---

# 22. Agent Knowledge

定義：

$$
K_i(t).
$$

---

# 23. World State

$$
S_t^{W}.
$$

---

# 24. Knowledge != World State

固定：

$$
\boxed{
K_i(t)
\neq
S_t^{W}.
}
$$

---

# 25. Agent Belief

$$
B_i(t).
$$

---

# 26. Belief != Knowledge

---

# 27. Knowledge != Observation

---

# 28. Observation != World

---

# 29. 四層分離

$$
\boxed{
S_t^{W}
\rightarrow
O_i(t)
\rightarrow
K_i(t)
\rightarrow
B_i(t)
}
$$

---

# 30. 不可反向等號

---

# 31. Observation Projection

$$
O_i(t)
=
\Pi_i
(
S_t^{W},
Sensor_i,
Position_i,
Authority_i
).
$$

---

# 32. 觀察受位置影響

---

# 33. 觀察受感測器影響

---

# 34. 觀察也可受權限影響

例如數位世界 private data。

---

# 35. 不同 Agent 可有不同 Observation

$$
O_i(t)\neq O_j(t).
$$

---

# 36. 但仍共享同一 World State

---

# 37. Perspective Consistency

如果兩 Agent 看同一 entity，

投影應在 tolerance 內一致。

---

# 38. Local Observation != Global Omniscience

---

# 39. 世界可以比 Agent Context 大很多

$$
|S_t^{W}|
\gg
|O_i(t)|.
$$

---

# 40. 這就是 streaming world 的必要條件

---

# 41. World State Structure

正式進入能力閉環。

---

# 93. Capability Realization in World

有些能力只有在 world 中成立。

---

# 94. Embodied Skill

$$
c_{\mathrm{manipulate}}
$$

需要：

- body；

# 95. Digital Skill

也可能需要：

- economic environment。

---

# 96. Therefore Effective Capability Is World-Conditioned

---

# 97. World State Can Be Capability Constraint

例如：

$$
DoorLocked=1.
$$

某 route 不可達。

---

# 98. World State Can Be Capability Enabler

$$

在 continuity 成立時。

---

# 103. Entity Mutation != Entity Replacement

例如人物換衣服，

identity 不變。

---

# 104. Identity Replacement

角色死亡後 clone？

# 127. World Reconstruction Contract

當 dormant region 被喚醒：

$$

$$

---

# 128. Need State Invariants

例如：

# 403. World Randomness Must Be Typed

不要把 model hallucination 當 world randomness。

# 416. World Rollback

高風險 event 可 rollback。

# 430. Persistent World and Legal/Economic State

如果 world 有：

# 601. 可證偽條件

### F1

若純生成式 video / latent world model 在沒有外部 canonical state 的情況下，可跨長時間、model swap、renderer swap、runtime restart 仍保持高 object persistence、causal consistency、multi-agent consistency 與 local correction，則本文對 persistent externalized world state 的必要性應下降。

### F2

若 renderer 與 simulator 在真實長期世界系統中幾乎不可區分，且視覺連續性高度預測因果正確性，則本文對兩者分離的強度需下降。

### F3

若 agent context 可以安全、低成本且無狀態漂移地同時充當 world state、agent memory 與 causal history，則 multi-domain separation 可被簡化。

### F4

若 off-screen state、world process、entity identity 在沒有 persistent state infrastructure 下也能長期可靠保持，則 persistent world runtime 的必要組件可縮減。

### F5

若 local correction / dependency-aware invalidation 無法比整體 regeneration 更有效，本文對局部世界修正的擴展性主張將被削弱。

### F6

若 world model 作為 capability substrate 無法改善 AI 的 planning、counterfactual、policy learning 或 causal validation，則其 DCAO capability role 應降低。

而一個真正的世界，也不是一段看起來連續的生成。

它必須能：

> **在沒有人看它時仍有狀態，在不同人看它時仍是一個世界，在被修改時保有因果，在被關閉後能被重建，在模型與 renderer 更換後仍能延續自己的歷史。**

這才是從：
