实现基于 IndexedDB 的权威世界存储与运行时 chunk 流式装载架构：

- WorldStore: IndexedDB 权威数据源，WorldMeta/RegionRecord/ChunkRecord 三级存储
- RegionCache: 内存缓存层，按需从 IndexedDB 加载 region，降低主线程阻塞
- PersistenceWorker: 新增 clearWorld/WorldMeta/RegionRecord 操作，支持 DB 版本升级
- Chunk.loadFromRecord: 纯装载路径，跳过 BlockScatterManager.scatter，降低装载延迟
- WorldGenerationService: 预生成阶段跨 region overflow 方块回退机制，防止跨边界结构丢失
- Player.setWorld: runtime-streaming 阶段不再隐式调 gen()，由 World 显式控制装载
- index.html: 新世界创建时 forceReset: true，自动清除旧 IndexedDB 数据

+# WorldStore Runtime Streaming Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** 将主世界改造成“进入前阻塞预生成、运行期只读权威世界数据、玩家交互统一命中 runtime blockData、接近边界时后台扩图并启用硬边界”的新流式架构。
+
+**Architecture:** 第一版采用双层重构路线：新增 `WorldStore + WorldRuntime + WorldAccessLayer + WorldGenerationService`，保留现有 `Chunk` 作为运行时视图容器。世界生成和 chunk 装载彻底分离；玩家交互通过统一访问层收口；权威世界存储在 IndexedDB，活动 chunk 以内存 `blockData` 提供实时交互与渲染输入。
+
+**Tech Stack:** Vanilla JS、Three.js、IndexedDB（通过现有 Persistence Worker 扩展）、ES Modules、浏览器测试页 `src/tests/index.html`、ESLint。

+# WorldStore Runtime Streaming 设计
+
+## 目标
+
+把主世界改造成以 IndexedDB 为权威数据源的预生成世界：
+
+- 进入主世界前阻塞预生成一片初始大地图
+- 运行期 chunk 装载只读取权威世界数据，不再即时生成地形或结构
+- 玩家与世界交互只命中运行时 `blockData`，不直接参与 IndexedDB 读写
+- 玩家接近地图边缘时后台扩图；扩图未完成前使用硬边界阻挡
+
+## 第一版范围
+
+第一版只支持新档，不兼容旧存档迁移。
+
+第一版必须同时覆盖：
+
+- 预生成大地图
+- runtime 纯装载
+- 玩家交互统一入口
+- 边界扩图与硬边界
+- 跨 chunk 结构/实体方块在预生成阶段一次性固化
+
+第一版暂不追求：
+
+- 旧存档兼容
+- 最优压缩存储格式
+- 独立拆分多个 worker 文件
+
+## 现状问题
+
+当前世界流式链路仍然把“生成世界”和“装载世界”混在一起：
+
+1. `Chunk` 创建时立即进入 `gen()`
+2. `ChunkGenerator.gen()` 先读持久化快照，再走统一 `WorldWorker` 协议
+3. `skipTerrainGeneration` 只是 worker 内部分支，不是独立装载管线
+4. 玩家交互大量依赖已加载 chunk 的裸内存结构
+5. 跨 chunk 结构处理与 runtime chunk 生命周期仍然耦合
+
+这会导致：
+
+- 奔跑时远端 chunk 仍然混入世界生成语义
+- 交互实现与 chunk 内部结构过度耦合
+- 很难把 IndexedDB 提升为真正权威世界
+
+## 核心原则
+
+### 1. WorldStore 才是权威真相
+
+第一版中，IndexedDB 上的 `WorldStore` 是最终权威：
+
+- `WorldMeta`
+- `RegionRecord`
+- `ChunkRecord`
+- 静态实体
+- 世界边界
+
+runtime `blockData` 只是某个活动 chunk 的内存视图，不是世界真相。
+
+### 2. 玩家只和运行时世界交互
+
+玩家及业务系统不直接等待 IndexedDB。
+
+上层通过 `WorldAccessLayer` 访问世界：
+
+- `getBlock`
+- `isSolid`
+- `setBlock`
+- `removeBlock`
+- `applyBatchEdits`
+- `getCollisionAt`
+
+这些操作底层优先命中运行时 `blockData`，数据库同步由底层自动处理。
+
+### 3. 生成和装载彻底分离
+
+预生成/扩图属于 `WorldGenerationService`。
+
+runtime chunk 加载只做：
+
+- 读取权威数据
+- 展开 `blockData`
+- 计算 AO / visible face / render payload
+- 分帧挂载渲染结果
+
+不再做：
+
+- 噪声地形生成
+- 结构放置
+- 跨 chunk owner 修补
+
+### 4. 跨 chunk 结构必须在预生成阶段固化
+
+跨 chunk 的树、建筑、结构方块、静态实体碰撞占位必须在 region 预生成时完整落地。
+
+运行时 chunk 装载只读取最终结果，不允许再补丁。
+
+## 系统分层
+
+### WorldStore
+
+权威世界存储接口，底层基于 IndexedDB。
+
+职责：
+
+- 读取/保存 `WorldMeta`
+- 读取/保存 `RegionRecord`
+- 投影读取某个 `ChunkRecord`
+- 合并写回 chunk 编辑
+
+### WorldGenerationService
+
+世界生成服务。
+
+职责：
+
+- 新档初始大地图阻塞预生成
+- 接近边界时后台扩图
+- 使用 region 级生成缓冲区处理跨 chunk 结构
+- 把结果写入 `WorldStore`
+
+### WorldRuntime
+
+运行时工作集层。
+
+职责：
+
+- 管理 `RegionCache`
+- 创建/释放 runtime chunk 视图
+- 调度 chunk 纯装载 worker
+- 维护脏 chunk 写回队列
+- 协调扩图与边界状态
+
+### WorldAccessLayer
+
+统一世界访问层。
+
+职责：
+
+- 统一查询与编辑入口
+- 屏蔽 chunk/view/store 差异
+- 统一跨 chunk 编辑
+- 统一边界阻挡逻辑
+
+### ChunkRenderPipeline
+
+纯渲染装载层。
+
+职责：
+
+- 从 runtime `blockData` 派生可见面/AO/mesh payload
+- 主线程分帧挂载渲染结果
+
+## 数据模型
+
+### WorldMeta
+
+保存：
+
+- `schemaVersion`
+- `worldId`
+- `seed`
+- `chunkSize`
+- `regionSizeInChunks`
+- `generatedBounds`
+- `safeBounds`
+- `expandTargetBounds`
+- `generationState`
+- `generatorVersion`
+- `playerSpawn`
+
+其中：
+
+- `generatedBounds` 是已生成世界边界
+- `safeBounds` 是玩家可活动边界
+- `expandTargetBounds` 是后台扩图目标边界
+
+### RegionRecord
+
+IndexedDB 的物理存储单元，建议固定为 `8x8` chunk。
+
+保存：
+
+- `regionKey`
+- `rx`
+- `rz`
+- `chunkKeys`
+- `chunks`
+- `generatedAt`
+- `generatorVersion`
+
+### ChunkRecord
+
+某个 chunk 的最终权威成品。
+
+保存：
+
+- `chunkKey`
+- `cx`
+- `cz`
+- `blockData`
+- `staticEntities`
+- `runtimeSeedData`
+- `structureCenters`
+
+要求：
+
+- `blockData` 已完成 owner 固化
+- 不能包含属于邻居 chunk 的权威方块
+
+### StaticEntityRecord
+
+用于表达不适合纯 `blockData` 表达的静态对象，例如特殊模型与碰撞占位。
+
+### RegionGenerationBuffer
+
+只存在于生成阶段，不落盘。
+
+保存：
+
+- region 级 `blockMap`
+- `staticEntities`
+- `structureCenters`
+- `collisionOccupancy`
+- `touchedChunkKeys`
+
+所有地形、结构、跨 chunk 方块先写这里，再按坐标所属 chunk 切分为多个 `ChunkRecord`。
+
+## BlockData 与 IndexedDB 的关系
+
+第一版中：
+
+- IndexedDB / `WorldStore` 更权威
+- runtime `blockData` 是内存工作集视图
+
+### 什么时候从 IndexedDB 读到 blockData
+
+1. 进入主世界后首次加载活动 chunk
+2. 玩家奔跑时加载新的远端 chunk
+3. chunk 卸载后重新进入，且 region 不在内存缓存中
+
+### 什么时候回写 IndexedDB
+
+1. 玩家放置/破坏方块后异步写回
+2. 持久化实体状态变化后异步写回
+3. chunk 卸载前脏数据兜底 flush
+4. 世界扩图生成完成后由生成服务直接写入
+
+### 不回写的派生数据
+
+以下数据不视为权威状态：
+
+- `visibleKeys`
+- `solidBlocks`
+- `blockDataArray`
+- AO 结果
+- mesh 数据
+
+这些都应当由 runtime `blockData` 重建。
+
+## 关键时序
+
+### 进入主世界前
+
+1. 新档初始化 `WorldMeta`
+2. `WorldGenerationService` 阻塞预生成初始世界
+3. 把生成结果写入 `WorldStore`
+4. 更新 `generatedBounds` 和 `safeBounds`
+5. 允许玩家出生
+
+### runtime chunk 装载
+
+1. `WorldRuntime` 计算需要加载的 chunk
+2. 优先从 `RegionCache` 读取
+3. 不命中时从 `WorldStore` 读取整个 `RegionRecord`
+4. 切出目标 `ChunkRecord`
+5. 创建 runtime chunk 视图并展开 `blockData`
+6. 派生 `blockDataArray / solidBlocks`
+7. 送入 `ChunkRenderPipeline`
+8. worker 只计算 AO / visible face / render payload
+9. 主线程分帧挂载渲染结果
+
+### 玩家交互
+
+1. `PlayerInteraction` / `Physics` 通过 `WorldAccessLayer` 调用
+2. `WorldAccessLayer` 定位活动 chunk
+3. 直接修改 runtime `blockData`
+4. 更新派生缓存、AO 脏位、渲染 patch
+5. 登记写回队列
+6. 异步合并到 `WorldStore`
+
+### 边界扩图
+
+1. 玩家接近 `safeBounds`
+2. 触发后台扩图
+3. 新 region 生成并写入 `WorldStore`
+4. 更新 `generatedBounds / safeBounds`
+5. 扩图完成前，硬边界阻挡玩家继续外扩
+
+## 模块落点
+
+### 新增模块
+
+- `src/world/WorldStore.js`
+- `src/world/WorldGenerationService.js`
+- `src/world/WorldAccessLayer.js`
+- `src/world/WorldRuntime.js`
+- `src/world/RegionCache.js`
+- `src/world/WorldBoundsController.js`
+
+### 保留并迁移职责
+
+- `src/world/World.js`
+- `src/world/Chunk.js`
+- `src/services/PersistenceService.js`
+- `src/world/ChunkGenerator.js`
+
+### worker 职责拆分
+
+第一版在现有 `WorldWorker` 中区分两种消息模式：
+
+- `generate-region`
+- `build-chunk-mesh`
+
+验证通过后再考虑物理拆分成两个 worker 文件。
+
+## 第一版验收标准
+
+### 功能
+
+- 进入世界前完成初始大地图预生成
+- runtime 奔跑时不再触发地形生成
+- 玩家挖掘/放置/碰撞行为保持正确
+- 接近边界时触发后台扩图
+- 扩图未完成前存在明确硬边界
+
+### 性能
+
+- 远端 chunk 装载链路不再混入世界生成成本
+- 玩家交互热路径不等待 IndexedDB
+- runtime chunk 装载主要消耗集中在 AO / 可见面 / 渲染挂载
+
+## 风险
+
+1. `PersistenceService.cache` 当前是 chunk 级 `Map`，需要升级为 region 工作集
+2. 现有 `Chunk` 过于中心化，职责迁移过程中容易遗漏调用点
+3. 批量编辑、爆炸、跨 chunk 交互需要统一走 `WorldAccessLayer`
+4. 预生成世界与运行时实体状态需要严格区分
+
+## 最终建议
+
+第一版优先顺序应为：
+
+1. 抽出 `WorldAccessLayer`
+2. 新增 `WorldStore`
+3. 实现新档初始预生成
+4. 切 runtime chunk 装载到 `WorldStore`
+5. 接入边界扩图与硬边界
+
+这样可以先做对世界真相与交互边界，再逐步替换 runtime 装载主链路。

Subject: [PATCH 06/66] feat(world): region-level worker pre-generation to
 eliminate duplicate large structure generation
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Refactor pre-generation from chunk-level independent worker calls to
region-level unified worker calls. This eliminates duplicate large
structure generation caused by multiple chunk tasks executing the same
candidate (the original problem: spacing logic prevents structure A
and B from overlapping, but can't prevent the same structure A being
executed by chunk(1,1), chunk(1,2), chunk(2,1), chunk(2,2) separately).

Key changes:
- Extract generateChunkWithSharedState() in WorldWorker.js — reusable
  chunk generation function with injectable shared state (candidate
  index, large structure dedup set)
- Add handleRegionGeneration() — coordinates 8x8 chunk region generation
  with shared candidate index and cross-chunk dedup
- Add resolveOverflowWithinRegion() with O(1) Set-based dedup — routes
  overflow blocks between chunks within the same region, replacing the
  main thread's _mergeOverflowBlocks
- Simplify WorldGenerationService._generateRegion() — from 100+ loop
  iterations with halo routing to a single worker.postMessage call
- Remove unnecessary post-processing in region path (scatteredBlocks,
  meshData, AO/visibility checks) — only blockDataBlocks + routing
  needed for region-level generation

Backward compatible: runtime chunk loading path unchanged. Old methods
(_generateChunkWithRouting, _mergeOverflowBlocks) preserved.

+# Region 级 Worker 预生成设计
+
+日期：2026-04-26
+状态：待实施（第一期：仅预生成；第二期：运行时路径）
+
+## 问题陈述
+
+当前预生成实现为 **chunk 级独立生成 + 主线程后合并**：
+
+- `WorldGenerationService._generateRegion()` 循环 100+ 次 `_generateChunkWithRouting(cx, cz)`
+- 每次都是一次独立的 `worker.postMessage({ cx, cz, ... })`
+- 每个 worker 调用各自构建 `StructureCandidateIndex`、各自维护 `largeStructureTaskKeySet`（per-chunk 去重）
+- 同一个大结构候选被多个相邻 chunk 的 worker 调用各自执行，导致重复生成
+- `CityMap` 的间距逻辑防的是"不同结构中心太近"，防不了"同一结构被多次执行"
+- Overflow 方块路由在主线程 `_mergeOverflowBlocks()` 后处理，增加复杂性
+
+**一句话归纳**：间距逻辑防的是 A 结构和 B 结构重叠；现在的问题是同一个 A 结构被 chunk(1,1)、chunk(1,2)、chunk(2,1)、chunk(2,2) 各执行一次。
+
+## 目标
+
+- **第一期**（本设计范围）：将预生成改为 **region 级统一生成 + worker 内部完成 ownership/缓冲/补刷**
+- **第二期**（后续）：考虑运行时 chunk 加载是否也走 region 级路径
+
+## 架构变更
+
+### 现状
+
+```
+WorldGenerationService._generateRegion(rx, rz)
+  └─ 循环 100+ 次 _generateChunkWithRouting(cx, cz)
+      └─ 每次独立 worker.postMessage({ cx, cz, ... })
+          └─ Worker 内部各自构建 candidates，各自 per-chunk 去重
+              └─ 主线程 _mergeOverflowBlocks() 路由跨 chunk 方块
+```
+
+### 改造后
+
+```
+WorldGenerationService._generateRegion(rx, rz)
+  └─ 一次 worker.postMessage({ type: 'generateRegion', rx, rz, ... })
+      └─ Worker 内部：
+          1. 构建 region 级 candidate index（tile cache 天然覆盖整个 region）
+          2. 维护 region 级 largeStructureTaskKeySet（跨 chunk 共享）
+          3. 按 chunk 逐个同步生成，共享同一个候选池
+          4. 内部完成 overflow routing
+          5. 返回完整 region 结果
+  └─ 主线程直接写入 WorldStore.saveRegionRecord()
+```
+
+## 组件设计
+
+### 1. Worker 侧 `generateRegion` 消息处理
+
+**文件**：`src/workers/WorldWorker.js`
+
+在 `onmessage` 入口增加 `message.type` 判断：
+
+```javascript
+onmessage = async function(e) {
+  const { type = 'generateChunk', ... } = e.data;
+
+  if (type === 'generateRegion') {
+    await handleRegionGeneration(e.data);
+    return;
+  }
+
+  // 现有 chunk 级生成逻辑（保持不变）
+  ...
+};
+```
+
+`handleRegionGeneration` 核心流程：
+
+1. 创建 region 级 `StructureCandidateIndex`（tile cache 自动跨 chunk 复用）
+2. 初始化 `regionLargeStructureTaskKeySet`（跨 chunk 共享去重）
+3. 按 chunk 逐个同步循环生成，调用 `generateChunkWithSharedState`
+4. 内部执行 `resolveOverflowWithinRegion` 完成方块路由
+5. 返回 `{ type: 'regionGenerated', rx, rz, chunks, routingDiagnostics }`
+
+### 2. `generateChunkWithSharedState`
+
+**文件**：`src/workers/WorldWorker.js`
+
+从现有 `onmessage` 中提取 chunk 级生成逻辑为独立函数，关键改动：
+
+- 接收外部传入 `candidateIndex`（替代内部 `new StructureCandidateIndex()`）
+- 接收外部传入 `largeStructureTaskKeySet`（替代内部 `new Set()`）
+- 接收外部传入 `structureQueueWithCenters`（替代局部变量）
+- 其余逻辑（地形生成、结构放置、snapshot 应用等）完全不变
+
+保证向后兼容：运行时路径仍走现有的独立 chunk 生成。
+
+### 3. `resolveOverflowWithinRegion`
+
+**文件**：`src/workers/WorldWorker.js`
+
+替代主线程的 `_mergeOverflowBlocks`，在 worker 内部同步执行：
+
+- 遍历 region 内所有 chunk 的 `routing.overflowChunks`
+- 如果目标 chunk 在当前 region 内，直接路由到正确 chunk 的 `blockData`
+- 如果目标 chunk 超出 region 范围，标记为 unresolved 并记录统计
+- 返回 `{ resolved, unresolved, diagnostics }`
+
+### 4. `WorldGenerationService._generateRegion` 精简
+
+**文件**：`src/world/WorldGenerationService.js`
+
+从当前的循环 100+ 次 `_generateChunkWithRouting` + `_mergeOverflowBlocks` 简化为：
+
+- 一次 `worker.postMessage({ type: 'generateRegion', rx, rz, taskId, seed })`
+- 回调中直接构建 `RegionRecord` 并写入 `WorldStore`
+
+## 向后兼容
+
+| 路径 | 变更 |
+|------|------|
+| 预生成（新档初始 + 后台扩图） | 走 `generateRegion` 新路径 |
+| 运行时 chunk 加载 | 保持现有 `generateChunk` 路径不动 |
+| Consolidation | 保持现有 `isOptimization` 路径不动 |
+| WorldWorkerPool | busy/idle 机制不变，仅单个任务耗时变长 |
+| StructureCandidateIndex | tile cache 天然适配，无需改动 |
+
+## 关键收益
+
+| 问题 | 现状 | 改造后 |
+|------|------|--------|
+| 大结构重复生成 | 多个 chunk 各自执行同一 candidate | region 级去重集合，只执行一次 |
+| Overflow 路由 | 主线程后处理 | Worker 内部同步解决 |
+| 间距逻辑与生成解耦 | 布局确定后多任务各自执行 | 生成与布局在同一作用域 |
+
+## 风险与缓解
+
+| 风险 | 缓解措施 |
+|------|----------|
+| 单个 region 生成耗时较长，占用 worker | 预生成是阻塞流程，用户本身在等待界面；同步串行避免并发协调复杂度 |
+| Overflow 方块可能落到 region 外 | 记录 unresolved 统计，后续扩图时可覆盖（二期考虑） |
+| 现有 chunk 生成逻辑提取为共享函数可能遗漏细节 | 通过 `generateChunkWithSharedState` 提取时保留所有现有逻辑，只注入外部状态 |
+
+## 第二期考虑（不在本设计范围）
+
+- 运行时 chunk 加载是否改为 region 级路径
+- Region 级生成结果的缓存与复用
+- 跨 region 的 overflow 路由机制

+# Region 级 Worker 预生成实施计划
+
+> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
+
+**Goal:** 将预生成从 "chunk 级独立生成 + 主线程后合并" 改造为 "region 级统一生成 + worker 内部完成 ownership/缓冲/补刷"，解决同一大结构被多个 chunk 任务重复执行的问题。
+
+**架构:** 在 WorldWorker.js 新增 `generateRegion` 消息类型，在单个 worker 调用内同步循环生成整个 region（8x8=64 个 chunk）的所有 chunk，共享 region 级候选索引和去重集合，内部完成 overflow routing 后一次性返回完整 region 结果。WorldGenerationService 的 `_generateRegion` 简化为单次 worker 调用。
+
+**技术栈:** Web Workers (WorldWorker.js), JavaScript ES Modules, WorldGenerationService
+
+**关键文件:**
+- `src/workers/WorldWorker.js` — Worker 入口，新增 region 生成逻辑
+- `src/world/WorldGenerationService.js` — 预生成服务，简化 `_generateRegion`
+- `src/workers/structure-index/StructureCandidateIndex.js` — 候选索引（无需改动）
+- `src/workers/structure-index/LargeStaticCandidateCollector.js` — 候选收集（无需改动）
+
+---
+
+## 实施策略
+
+- **TDD 不适用**: 这是重构型任务，项目没有 CLI 测试框架，测试通过浏览器内测试完成
+- **DRY**: 提取 `generateChunkWithSharedState` 复用现有 chunk 生成逻辑
+- **YAGNI**: 只做预生成路径，运行时 chunk 加载不动
+- **频繁提交**: 每个 Task 完成后单独提交
+
+---
+
+### Task 1: Worker 侧 — 提取 `generateChunkWithSharedState` 函数
+
+**Files:**
+- Modify: `src/workers/WorldWorker.js`
+
+**目标:** 将 `onmessage` 中的 chunk 生成逻辑提取为可复用函数，支持注入外部状态。
+
+**Step 1: 分析现有逻辑边界**
+
+阅读 `WorldWorker.js` 的 `onmessage` handler（line 477-1937），识别需要参数化的部分：
+
+- `structureCandidateIndex` → 改为可注入参数
+- `largeStructureTaskKeySet` → 改为可注入参数
+- `structureQueueWithCenters` → 改为可注入参数
+- `blockMap`, `modGunMan`, `rovers`, `structureCenters` 等局部变量 → 保持内部创建
+- `fakeChunk` → 保持内部创建
+- `savedSnapshot` → region 生成时为 null
+- `isOptimization` → false
+- `skipTerrainGeneration` → false
+
+**Step 2: 创建 `generateChunkWithSharedState` 函数**
+
+在 `WorldWorker.js` 的 `onmessage` 之前（约 line 470 处）添加新函数：
+
+```javascript
+/**
+ * 生成单个 chunk，使用外部注入的共享状态。
+ * 用于 region 级生成路径，多个 chunk 共享同一个候选索引和去重集合。
+ *
+ * @param {Object} params
+ * @param {number} params.cx - Chunk X
+ * @param {number} params.cz - Chunk Z
+ * @param {number} params.seed - 世界种子
+ * @param {StructureCandidateIndex} params.candidateIndex - 共享的候选索引
+ * @param {Set} params.largeStructureTaskKeySet - 共享的大结构去重集合
+ * @param {Array} params.structureQueueWithCenters - 共享的结构生成队列
+ * @param {Array} params.structureCenters - 共享的结构中心列表
+ * @param {Array} params.modGunMan - 共享的 gun_man 实体列表
+ * @param {Array} params.rovers - 共享的 rover 实体列表
+ * @returns {Object} chunk 结果 { blockDataBlocks, scatteredBlocks, routing, meshData, ... }

+2. `largeStructureTaskKeySet`（原为局部变量）→ 使用参数
+3. `structureQueueWithCenters`（原为局部变量）→ 使用参数
+4. `pushStructureCenter` 内部操作 → push 到 `params.structureCenters`

+### Task 2: Worker 侧 — 实现 `handleRegionGeneration` 函数
+
+**Files:**
+- Modify: `src/workers/WorldWorker.js`
+
+**目标:** 实现 region 级生成入口函数，协调 chunk 循环、overflow 路由和结果返回。
+
+**Step 1: 创建 `handleRegionGeneration` 函数**
+
+在 `generateChunkWithSharedState` 之后添加：
+
+```javascript
+/**
+ * Region 级生成入口函数。
+ * 在单个 worker 调用内同步循环生成整个 region 的所有 chunk，
+ * 共享候选索引和去重集合，内部完成 overflow routing。
+ */

+    rx, rz,
+    chunks: regionChunks,
+    routingDiagnostics,
+    taskId
+  });
+}
+```
+
+**Step 2: 创建 `resolveOverflowWithinRegion` 函数**
+
+```javascript
+/**
+ * 在 Worker 内部完成 region 内的 overflow 方块路由。
+ * 替代主线程的 _mergeOverflowBlocks。
+ */
+function resolveOverflowWithinRegion(regionChunks, rx, rz, regionChunkSize) {

+  const regionMaxCx = regionMinCx + regionChunkSize - 1;
+  const regionMinCz = rz * regionChunkSize;
+  const regionMaxCz = regionMinCz + regionChunkSize - 1;
+
+  for (const [sourceKey, result] of Object.entries(regionChunks)) {
+    if (!result.routing?.overflowChunks) continue;
+

+      const [targetCx, targetCz] = overflowEntry.chunkKey.split(',').map(Number);
+      const isInRegion = (

+      );
+
+      if (!isInRegion) {

+          unresolvedCoords.add(encodeCoord(block.x, block.y, block.z));
+        }
+        continue;
+      }
+
+      const targetResult = regionChunks[overflowEntry.chunkKey];
+      if (!targetResult) continue;
+
+      for (const block of (overflowEntry.blockDataBlocks || [])) {
+        const code = encodeCoord(block.x, block.y, block.z);
+        if (targetResult.blockData[code] === undefined) {
+          // 将 overflow 方块追加到目标 chunk 的 routing.ownChunk.blockDataBlocks

+      .slice(0, 5)
+      .map(([offset, blocks]) => ({ offset, blocks }))
+  };
+}
+```
+
+**Step 3: 在 `onmessage` 入口添加 type 分发**
+
+修改 `WorldWorker.js` line 477 附近的 `onmessage` 入口：
+
+```javascript
+onmessage = async function(e) {
+  const { type = 'generateChunk', ... } = e.data;
+
+  if (type === 'generateRegion') {
+    await handleRegionGeneration(e.data);
+    return;
+  }
+
+  // ... 现有 generateChunk 逻辑保持不变 ...
+};
+```
+
+需要从 `e.data` 中解构时加上 `type`：
+
+```javascript
+// 原代码:
+const {
+  cx, cz, seed, snapshot, structureCenters: incomingStructureCenters,
+  callbackKey, taskId, isOptimization = false,
+  _consolidationRequestSentAt = 0, textureGroups = {},
+  skipTerrainGeneration = false
+} = e.data;
+
+// 改为:
+const {
+  type = 'generateChunk',
+  cx, cz, seed, snapshot, structureCenters: incomingStructureCenters,
+  callbackKey, taskId, isOptimization = false,
+  _consolidationRequestSentAt = 0, textureGroups = {},
+  skipTerrainGeneration = false
+} = e.data;
+```
+
+**Step 4: 验证**
+
+```bash
+npm run lint
+```
+

+
+### Task 3: 主线程 — 精简 `WorldGenerationService._generateRegion`
+
+**Files:**
+- Modify: `src/world/WorldGenerationService.js`
+
+**目标:** 将 `_generateRegion` 从循环 100+ 次 `_generateChunkWithRouting` + `_mergeOverflowBlocks` 简化为单次 worker 调用。
+
+**Step 1: 重写 `_generateRegion` 方法**
+
+替换 `WorldGenerationService.js` 中 `_generateRegion` 方法（约 line 213-270）：
+
+```javascript
+/**
+ * 生成单个 region（8x8 chunk）
+ *
+ * 策略：一次 worker 调用完成整个 region 的生成，
+ * worker 内部共享候选索引和去重集合，完成 overflow routing。
+ */
+async _generateRegion(rx, rz) {
+  const regionKey = this._regionKey(rx, rz);
+
+  return new Promise((resolve) => {
+    const taskId = `pregen-region:${rx},${rz}:${Date.now()}`;
+
+    workerCallbacks.set(taskId, (data) => {
+      // 构建 RegionRecord：直接使用 worker 返回的 chunks
+      const chunks = {};
+      const chunkKeys = [];
+
+      for (const [chunkKey, result] of Object.entries(data.chunks)) {
+        const [cx, cz] = chunkKey.split(',').map(Number);
+        if (!this._isChunkInRegion(cx, cz, rx, rz)) continue;
+
+        chunkKeys.push(chunkKey);
+        chunks[chunkKey] = {
+          blockData: this._buildBlockDataFromRouting(result),
+          staticEntities: this._buildStaticEntities(result),
+          runtimeSeedData: {
+            structureCenters: result.structureCenters || []
+          }
+        };
+      }
+
+      const regionRecord = {
+        regionKey,
+        rx,
+        rz,
+        chunkKeys,
+        chunks,
+        generatedAt: Date.now(),
+        generatorVersion: '1.0',
+        routingDiagnostics: data.routingDiagnostics
+      };
+
+      getWorldStore().saveRegionRecord(rx, rz, regionRecord);
+
+      if (data.routingDiagnostics?.unresolved > 0) {
+        console.warn('[WorldGenerationService] Region generation had unresolved overflow blocks', {
+          regionKey,
+          ...data.routingDiagnostics
+        });
+      }
+
+      resolve(regionRecord);
+    });
+
+    getWorldWorker().postMessage({
+      type: 'generateRegion',
+      rx,
+      rz,
+      taskId,
+      seed: this._seed
+    });
+  });
+}
+```
+
+**Step 2: 添加 `_buildBlockDataFromRouting` 辅助方法**
+
+```javascript
+/**
+ * 从 chunk 结果中提取 blockData（优先使用 routing.ownChunk + 已路由的 overflow）。
+ */
+_buildBlockDataFromRouting(result) {
+  const blockData = {};
+
+  // 优先使用 routing.ownChunk 的 blockDataBlocks
+  const blocks = result.routing?.ownChunk?.blockDataBlocks || result.blockDataBlocks || [];
+  for (const block of blocks) {
+    const code = encodeCoord(block.x, block.y, block.z);
+    const entry = block.orientation ? { type: block.type, orientation: block.orientation } : block.type;
+    blockData[code] = entry;
+  }
+
+  return blockData;
+}
+```
+
+**Step 3: 保留但不使用的旧方法**
+
+以下方法保留（未来扩图路径或运行时路径可能使用），但 `_generateRegion` 不再调用：
+- `_generateChunkWithRouting` — 保留注释标记 `@deprecated 仅用于兼容，预生成已改用 region 级路径`
+- `_mergeOverflowBlocks` — 同上
+
+**Step 4: 验证**
+
+```bash
+npm run lint
+```
+
+---
+
+### Task 4: 冒烟测试与提交
+
+**Files:**
+- 无文件变更
+
+**Step 1: 启动开发服务器**
+
+```bash
+npm run start
+```
+
+**Step 2: 浏览器内测试**
+
+1. 打开浏览器，访问 `http://localhost:8080`
+2. 创建一个新存档（触发预生成）
+3. 在浏览器控制台观察日志：
+   - 应该看到 `[WorldGenerationService] Region X,Y done` 格式的日志
+   - 不应该看到大结构重复生成的警告
+   - 检查 `routingDiagnostics.unresolved` 是否为 0 或接近 0
+4. 确认玩家出生在世界中心附近，周围地形正常生成
+5. 向各个方向移动，确认地形加载正常
+
+**Step 3: 提交**
+
+```bash
+git add src/workers/WorldWorker.js src/world/WorldGenerationService.js
+git commit -m "feat(world): region-level worker pre-generation
+
+Refactor pre-generation from chunk-level independent calls to
+region-level unified worker calls. This eliminates duplicate
+large structure generation caused by multiple chunk tasks
+executing the same candidate.
+
+- Extract generateChunkWithSharedState() in WorldWorker.js
+- Add handleRegionGeneration() with shared candidate index
+  and cross-chunk dedup set
+- Add resolveOverflowWithinRegion() for in-worker routing
+- Simplify WorldGenerationService._generateRegion() to
+  single worker.postMessage call
+- Backward compatible: runtime chunk loading path unchanged"
+```

+
+## 风险清单
+
+| 风险 | 应对 |
+|------|------|
+| `generateChunkWithSharedState` 提取时遗漏某些变量引用 | 仔细对比 onmessage 中所有被引用的局部变量 |
+| Region 生成耗时过长导致 worker pool 阻塞 | 第一期仅预生成（阻塞流程），不影响运行时 |
+| Overflow 方块落到 region 外 | 记录 diagnostics 统计，二期处理 |
+| `structureCandidateIndex` 在 region 生成时 tile cache 不够大 | tile 扫描范围是自动计算的，覆盖整个 region 没问题 |

Subject: [PATCH 09/66] fix(world): fix 4 P0 data-correctness defects in region
 pre-generation

- sync seed in region-level worker path (WorldWorker.js:1392)
  handleRegionGeneration now calls setSeed(seed) before generation,
  ensuring terrainGen/noise use the same seed as the runtime chunk path.

- await structure preload before region generation (WorldWorker.js:1393)
  handleRegionGeneration now awaits structuresPreload, preventing
  silent omission of JSON-driven buildings on cold worker starts.

- filter per-chunk entities to prevent 64x data bloat (WorldWorker.js:1279)
  generateChunkWithSharedState now filters modGunMan/rovers to only
  entities within the current chunk bounds before returning.

- await saveRegionRecord with proper error propagation (WorldGenerationService.js)
  _generateRegion now rejects on persistence failure so the caller
  knows the region was not saved. generateInitialWorld and
  expandWorldIfNeeded wrap per-region calls in try/catch to skip
  failed regions without blocking the entire pre-generation flow.

Closes #68

+# Fix P0 Region Generation Bugs - Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Fix 4 data-correctness defects in the region-level pre-generation pipeline: seed sync, missing structure preload, entity array bloat, and async persistence race condition.
+
+**Architecture:** Minimal surgical fixes in two files. `WorldWorker.js` gets seed sync, preload await, and per-chunk entity filtering. `WorldGenerationService.js` gets an `await` on `saveRegionRecord`. No refactors, no format changes.
+
+**Tech Stack:** Vanilla ES Modules, no bundler. Browser-based tests via `src/tests/index.html`. Lint via `npm run lint`.
+
+---
+
+## File Map
+
+| File | Responsibility | Change Type |
+|------|---------------|-------------|
+| `src/workers/WorldWorker.js` | Worker-side region generation and chunk generation | Modify 3 locations |
+| `src/world/WorldGenerationService.js` | Main-thread orchestration of region pre-generation | Modify 1 location |
+
+---
+
+### Task 1: Seed Sync in `handleRegionGeneration`
+
+**Files:**
+- Modify: `src/workers/WorldWorker.js:1376` (`handleRegionGeneration`)
+
+**Context:** The chunk-level path in `onmessage` calls `setSeed(seed)` before generation. The region-level path (`handleRegionGeneration`) does not. `terrainGen.getBiome()` and `noise()` rely on `WORLD_CONFIG.SEED` global state. If a custom seed is passed, pre-generated terrain will diverge from runtime terrain.
+
+- [ ] **Step 1: Add `setSeed(seed)` to `handleRegionGeneration`**
+
+  In `src/workers/WorldWorker.js`, at the very top of `handleRegionGeneration`, add the seed sync call right after destructuring `data`:
+
+  ```javascript
+  async function handleRegionGeneration(data) {
+    const { rx, rz, seed, taskId } = data;
+    const REGION_CHUNK_SIZE = 8;
+
+    // Sync seed so terrainGen and noise() use the same seed as the runtime path
+    setSeed(seed);
+
+    // 1. Region-level shared state
+    const regionCandidateIndex = new StructureCandidateIndex();
+    ...
+  ```
+
+- [ ] **Step 2: Verify `setSeed` is in scope**
+
+  `setSeed` is already imported/defined at the module level in `WorldWorker.js` (used by the chunk-level path at line 1450). No additional imports needed.
+
+- [ ] **Step 3: Run lint**
+
+  ```bash
+  npm run lint
+  ```
+
+  Expected: No new errors or warnings in `src/workers/WorldWorker.js`.
+
+---
+
+### Task 2: Await Structure Preload in `handleRegionGeneration`
+
+**Files:**
+- Modify: `src/workers/WorldWorker.js:1376` (`handleRegionGeneration`)
+
+**Context:** `structuresPreload` is a module-level Promise in `WorldWorker.js` (line 57). The chunk-level path awaits it before generation. The region-level path does not. On a cold worker start, `generateRegion` may run before JSON structures are loaded, causing silent omission of all JSON-driven buildings.
+
+- [ ] **Step 1: Add `await structuresPreload` to `handleRegionGeneration`**
+
+  Immediately after `setSeed(seed)` from Task 1, add:
+
+  ```javascript
+  async function handleRegionGeneration(data) {
+    const { rx, rz, seed, taskId } = data;
+    const REGION_CHUNK_SIZE = 8;
+
+    // Sync seed so terrainGen and noise() use the same seed as the runtime path
+    setSeed(seed);
+
+    // Wait for structure JSON data to be ready before generating
+    await structuresPreload;
+
+    // 1. Region-level shared state
+    const regionCandidateIndex = new StructureCandidateIndex();
+    ...
+  ```
+

+
+### Task 3: Per-Chunk Entity Filtering in `generateChunkWithSharedState`
+
+**Files:**
+- Modify: `src/workers/WorldWorker.js:1279` (`generateChunkWithSharedState` return statement)
+
+**Context:** `modGunMan` and `rovers` are region-level shared arrays that accumulate entities across all 64 chunks in a region. Currently `generateChunkWithSharedState` returns `[...modGunMan]` and `[...rovers]`, meaning later chunks persist the entire region's entity list. This causes ~64x data bloat in IndexedDB.
+
+**Fix:** Filter entities to only those whose coordinates fall within the current chunk's bounds before returning.
+
+- [ ] **Step 1: Add filtering logic before the return statement**
+
+  In `src/workers/WorldWorker.js`, inside `generateChunkWithSharedState`, replace the final `return` block (around line 1279) with:
+
+  ```javascript
+  // region 生成路径没有 snapshot，直接构建方块数据
+  const blockDataBlocks = buildBlockDataBlocks(blockMap);
+  const routing = buildChunkRouting(blockDataBlocks, [], cx, cz, []);
+
+  // 过滤实体：只保留坐标落在当前 chunk 边界内的实体
+  const chunkMinX = cx * CHUNK_SIZE_LOCAL;
+  const chunkMaxX = (cx + 1) * CHUNK_SIZE_LOCAL;
+  const chunkMinZ = cz * CHUNK_SIZE_LOCAL;
+  const chunkMaxZ = (cz + 1) * CHUNK_SIZE_LOCAL;
+
+  const isInChunkBounds = (e) => (
+    e.x >= chunkMinX && e.x < chunkMaxX &&
+    e.z >= chunkMinZ && e.z < chunkMaxZ
+  );
+
+  const chunkModGunMan = modGunMan.filter(isInChunkBounds);
+  const chunkRovers = rovers.filter(isInChunkBounds);
+
+  return {
+    blockDataBlocks,
+    routing,
+    modGunMan: chunkModGunMan,
+    rovers: chunkRovers,
+    structureCenters: [...structureCenters],
+    entities: { modGunMan: chunkModGunMan, rovers: chunkRovers }
+  };
+  ```
+
+  **Important:** `CHUNK_SIZE_LOCAL` is already defined as `16` at the top of `generateChunkWithSharedState` (line 503).
+
+- [ ] **Step 2: Confirm the old return statement is fully replaced**
+
+  The old code was:
+  ```javascript
+  return {
+    blockDataBlocks,
+    routing,
+    modGunMan: [...modGunMan],
+    rovers: [...rovers],
+    structureCenters: [...structureCenters],
+    entities: { modGunMan: [...modGunMan], rovers: [...rovers] }
+  };
+  ```
+
+  Ensure it is replaced by the filtered version above.
+
+- [ ] **Step 3: Run lint**
+
+  ```bash
+  npm run lint
+  ```
+
+  Expected: No new errors or warnings.
+
+---
+
+### Task 4: Await `saveRegionRecord` in `_generateRegion`
+
+**Files:**
+- Modify: `src/world/WorldGenerationService.js:247` (`_generateRegion` worker callback)
+
+**Context:** `_generateRegion` calls `getWorldStore().saveRegionRecord(...)` without `await`, then immediately `resolve(regionRecord)`. The caller (`generateInitialWorld`) may proceed while the IndexedDB write is still in flight. If the page crashes or reloads at this moment, the region data is lost.
+
+- [ ] **Step 1: Add `await` to `saveRegionRecord`**
+
+  In `src/world/WorldGenerationService.js`, inside the `workerCallbacks.set(taskId, (data) => { ... })` block, change:
+
+  ```javascript
+  // Before:
+  getWorldStore().saveRegionRecord(rx, rz, regionRecord);
+
+  // After:
+  await getWorldStore().saveRegionRecord(rx, rz, regionRecord);
+  ```
+
+  The surrounding callback function is already inside a `new Promise((resolve) => { ... })` block, so adding `await` is valid — the callback itself does not need to be marked `async` because the worker callback mechanism does not expect a return value; it just needs to delay the `resolve()` call.
+
+  Wait — the callback is `workerCallbacks.set(taskId, (data) => { ... })`. To use `await`, the callback must be `async`. Change the callback signature:
+
+  ```javascript
+  workerCallbacks.set(taskId, async (data) => {
+    // ... build regionRecord ...
+
+    await getWorldStore().saveRegionRecord(rx, rz, regionRecord);
+
+    resolve(regionRecord);
+  });
+  ```
+
+- [ ] **Step 2: Verify no other callers are broken**
+
+  Check how `workerCallbacks` invokes its stored callbacks. In `ChunkConsolidation.js` or wherever `workerCallbacks` fires, it should simply call `callback(data)` without awaiting the return value. An `async` callback returns a Promise that is safely ignored by synchronous callers.
+
+  Search for where worker callbacks are invoked:
+  ```bash
+  grep -n "workerCallbacks.get\|workerCallbacks.forEach" src/**/*.js
+  ```
+  Or inspect `src/world/ChunkConsolidation.js` for the callback dispatch logic. The typical pattern is:
+  ```javascript
+  const callback = workerCallbacks.get(taskId);
+  if (callback) callback(data);
+  ```
+  Calling an `async` function this way is safe — the Promise is fire-and-forget from the dispatcher's perspective, which is exactly what we want.
+
+- [ ] **Step 3: Run lint**
+
+  ```bash
+  npm run lint
+  ```
+
+  Expected: No new errors or warnings.
+
+---
+
+### Task 5: Verify Existing Cross-Region Tests Still Pass
+
+**Files:**
+- Test: `src/tests/test-world-generation-cross-region.js`
+
+**Context:** This test file mocks `_worldStore.saveRegionRecord` as an async function and validates region ownership rules. The Task 4 change makes `_generateRegion` actually await the mock, which should improve test reliability.
+
+- [ ] **Step 1: Start the dev server**
+
+  ```bash
+  npm run start
+  ```
+
+- [ ] **Step 2: Open the test page in a browser**
+
+  Navigate to `http://localhost:8080/src/tests/index.html`
+
+- [ ] **Step 3: Run the cross-region test**
+
+  Look for the test group labeled "WorldGenerationService 跨 region owner 归属测试" and run it.
+
+  Expected: All 3 tests pass.
+  - `_mergeOverflowBlocks - 应返回可诊断的 unresolved overflow 摘要`
+  - `generateRegion - 源 region 不应借用保存越界方块`
+  - `generateRegion - 目标 region 应通过 halo 生成拿到跨界方块`
+
+---
+
+### Task 6: Final Lint and Review
+
+- [ ] **Step 1: Run full lint**
+
+  ```bash
+  npm run lint
+  ```
+
+  Expected: No new errors or warnings across the two modified files.
+
+- [ ] **Step 2: Review diff**
+
+  ```bash
+  git diff
+  ```
+
+  Expected changes:
+  - `src/workers/WorldWorker.js`: 3 insertions (`setSeed`, `await structuresPreload`, entity filtering)
+  - `src/world/WorldGenerationService.js`: 1 insertion (`async` callback + `await saveRegionRecord`)
+
+- [ ] **Step 3: Do NOT commit**
+
+  Per user instruction, wait for explicit confirmation before committing. Stage the files if desired but do not run `git commit`.
+
+---

+# P0 Region Generation 缺陷修复设计
+
+## 背景
+在 `gen-big-map-first` 分支的 region 级预生成架构中，代码 review 识别出 4 个影响数据正确性的 P0 缺陷。本设计描述修复方案。
+
+## 缺陷清单与修复方案
+
+### 1. 种子同步（严重）
+
+**问题**：`WorldWorker.js` 的 `handleRegionGeneration` 没有调用 `setSeed(seed)`，而 chunk 级路径有。虽然 `generateChunkWithSharedState` 内部大量使用显式 `seed` 参数，但 `terrainGen.getBiome()` 等调用链最终会落到依赖 `WORLD_CONFIG.SEED` 全局状态的函数。一旦 `WorldGenerationService` 传入自定义种子，预生成结果将与运行时生成不一致。
+
+**修复**：在 `handleRegionGeneration` 开头加入 `setSeed(seed)`，与 chunk 级路径保持一致。
+
+**修改**：`src/workers/WorldWorker.js`，`handleRegionGeneration` 函数内第一行。
+
+---
+
+### 2. 缺失结构预加载（严重）
+
+**问题**：`handleRegionGeneration` 没有 `await structuresPreload`。Worker 启动后的第一条消息如果是 `generateRegion`，结构 JSON 尚未加载完成，所有 JSON 驱动的结构会静默缺失。
+
+**修复**：在 `handleRegionGeneration` 开头 `await structuresPreload`。
+
+**修改**：`src/workers/WorldWorker.js`，`handleRegionGeneration` 函数内。
+
+---
+
+### 3. 实体数据膨胀（高危）
+
+**问题**：`generateChunkWithSharedState` 返回的 `entities.modGunMan` 和 `entities.rovers` 是对 region 级共享数组的浅拷贝（spread）。在 8×8 region 的 64 个 chunk 生成过程中，这些数组持续累积。后生成的 chunk 会冗余保存整个 region 的所有实体，导致 IndexedDB 数据膨胀约 64 倍。
+
+**修复方案 A（采用）**：在 `generateChunkWithSharedState` 返回前，根据当前 chunk 的边界坐标 `[cx*16, (cx+1)*16) × [cz*16, (cz+1)*16)` 对 `modGunMan` 和 `rovers` 进行过滤，每个 chunk 只保存落入自己边界内的实体。
+
+**修改**：`src/workers/WorldWorker.js`，`generateChunkWithSharedState` 的 `return` 语句前增加过滤逻辑。
+
+**边界规则**：使用半开区间 `min <= coord < max`，与 chunk 坐标系统一致。
+
+---
+
+### 4. 异步状态竞态（中等）
+
+**问题**：`WorldGenerationService._generateRegion` 中调用 `getWorldStore().saveRegionRecord(...)` 后没有 `await` 就 `resolve(regionRecord)`。上层可能误判生成完成，而底层持久化仍在飞行中。若此时游戏崩溃或刷新，region 数据可能丢失。
+
+**修复**：将 `saveRegionRecord` 改为 `await`，确保持久化完成后再 `resolve`。
+
+**修改**：`src/world/WorldGenerationService.js`，`_generateRegion` 的 worker callback 内。
+
+---
+
+## 影响面分析
+
+| 修改文件 | 运行时路径是否受影响 | 旧存档兼容性 |
+|---------|-------------------|------------|
+| `WorldWorker.js` | 否（`handleRegionGeneration` / `generateChunkWithSharedState` 仅用于预生成路径） | 兼容（RegionRecord 格式不变） |
+| `WorldGenerationService.js` | 否（仅 `_generateRegion` 内部时序调整） | 兼容 |
+
+## 验证方式
+
+1. 重新预生成世界后，检查 `WorldStore` 中任意 region 的 chunk 实体数据，确认每个 chunk 的 `modGunMan`/`rovers` 数量合理（不再包含远超出 chunk 边界的坐标）。
+2. 在 `_generateRegion` 的 `resolve` 前加日志，确认 `saveRegionRecord` Promise 已 resolved。
+3. 冷启动（清空 IndexedDB 后）预生成包含 JSON 结构的区域（如 City），确认建筑正常出现。

Subject: [PATCH 12/66] feat(world-worker): return unresolved cross-region
 overflow blocks from region generation

Modify resolveOverflowWithinRegion to collect and return unresolved
cross-region overflow block data, so the main thread can distribute
them later.

Subject: [PATCH 13/66] feat(world-generation): collect, distribute, and
 persist cross-region overflow blocks

- Add _crossRegionOverflowMap in constructor to stage inter-region overflow blocks.
- Add _collectCrossRegionOverflow to gather unresolvedOverflowBlocks from worker results.
- Add _distributeCrossRegionOverflow to merge overflow into already-generated regions
  in the same batch, or persist leftovers to world_overflow store for future expansion.
- Add _consumeOverflowForRegion to merge previously persisted overflow blocks when
  a new region is generated during world expansion.
- Wire collection into _generateRegion callback after saving region record.
- Wire distribution into generateInitialWorld after all regions in the batch finish.
- Wire consumption + re-distribution into expandWorldIfNeeded after expansion regions
  are generated and before bounds are updated.

Subject: [PATCH 15/66] perf(world): cross-region overflow pure-memory routing
 to unblock main thread

- Remove IndexedDB persistence for cross-region overflow blocks.
  Overflow is now kept in _crossRegionOverflowMap and merged
  automatically when the target region is generated during expansion.
- Add _yieldIfNeeded helper to yield the main thread every 5000
  iterations in dense loops, preventing FPS drops after game entry.
- Remove _consumeOverflowForRegion and background overflow
  distribution from generateInitialWorld, eliminating the long
  loading-modal hang after pre-generation.
- _generateRegion now merges pending overflow before saving the
  region record.
- Update tests to match pure-memory semantics (DB_VERSION 3,
  async _collectCrossRegionOverflow, removed persistence tests).
- Add design doc and implementation plan for cross-region overflow.

+# 跨 Region Overflow Block 路由机制实现计划
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** 实现跨 region 的 overflow block 收集、分发与持久化机制，修复 region 级预生成时跨边界结构方块被静默丢弃的 P0 缺陷。
+
+**Architecture:** Worker 返回未解析的跨 region overflow 数据，主线程暂存到内存 Map，批次生成完成后分发给同批次目标 region，剩余部分持久化到 IndexedDB `world_overflow` store；扩图时自动消费已持久化的 overflow。
+
+**Tech Stack:** ES Modules, IndexedDB, Web Worker, 自定义浏览器测试 runner (`src/tests/runner.js`)

+### Task 1: PersistenceWorker.js — 新增 `world_overflow` IndexedDB store
+
+**Files:**
+- Modify: `src/constants/PersistenceConfig.js`
+- Modify: `src/workers/PersistenceWorker.js`
+
+- [ ] **Step 1: 升级 IndexedDB 版本号**
+
+修改 `src/constants/PersistenceConfig.js` 第 7 行：
+
+```javascript
+DB_VERSION: 3, // v3: 新增 world_overflow store（跨 region overflow 持久化）
+```
+
+- [ ] **Step 2: 在 PersistenceWorker.js 顶部新增 store 常量**
+
+在 `src/workers/PersistenceWorker.js` 第 9 行后添加：
+
+```javascript
+const WORLD_OVERFLOW_STORE = 'world_overflow';
+```
+
+- [ ] **Step 3: 在 init() 升级回调中创建 world_overflow store**
+
+在 `init()` 函数内（约第 27-35 行），在 `WORLD_REGION_STORE` 创建后添加：
+
+```javascript
+if (!dbInstance.objectStoreNames.contains(WORLD_OVERFLOW_STORE)) {
+  dbInstance.createObjectStore(WORLD_OVERFLOW_STORE, { keyPath: 'regionKey' });
+}
+```
+
+同时，在第 17 行的旧连接检测逻辑中，补充对 `WORLD_OVERFLOW_STORE` 的检测：
+
+```javascript
+if (db && !db.objectStoreNames.contains(WORLD_META_STORE)) {
+  db.close();
+  db = null;
+}
+if (db && !db.objectStoreNames.contains(WORLD_OVERFLOW_STORE)) {
+  db.close();
+  db = null;
+}
+```
+
+- [ ] **Step 4: 新增 save/get/remove overflow 函数**
+
+在 `clearWorld()` 函数之前（约第 163 行前）添加三个函数：
+
+```javascript
+/**
+ * 保存跨 region overflow blocks
+ * @param {string} regionKey - "rx,rz"
+ * @param {object} overflowData - { "cx,cz": [{x,y,z,type,orientation}, ...] }
+ */
+function saveOverflowBlocks(regionKey, overflowData) {
+  return performTransaction(db, WORLD_OVERFLOW_STORE, 'readwrite', (store) =>
+    store.put({ regionKey, data: overflowData, lastModified: Date.now() })
+  );
+}
+
+/**
+ * 读取跨 region overflow blocks
+ * @param {string} regionKey - "rx,rz"
+ * @returns {Promise<object|null>} { "cx,cz": [...] }
+ */
+function getOverflowBlocks(regionKey) {
+  return performTransaction(db, WORLD_OVERFLOW_STORE, 'readonly', (store) =>
+    store.get(regionKey)
+  ).then((result) => result ? result.data : null);
+}
+
+/**
+ * 删除跨 region overflow blocks
+ * @param {string} regionKey - "rx,rz"
+ */
+function removeOverflowBlocks(regionKey) {
+  return performTransaction(db, WORLD_OVERFLOW_STORE, 'readwrite', (store) =>
+    store.delete(regionKey)
+  );
+}
+```
+
+- [ ] **Step 5: 修改 onmessage switch 处理新 action**
+
+在 `switch (action)` 的 `case 'clearWorld'` 之前添加三个 case：
+
+```javascript
+case 'saveOverflowBlocks':
+  await saveOverflowBlocks(payload.regionKey, payload.overflowData);
+  result = true;
+  break;
+case 'getOverflowBlocks':
+  result = await getOverflowBlocks(payload.regionKey);
+  break;
+case 'removeOverflowBlocks':
+  await removeOverflowBlocks(payload.regionKey);
+  result = true;
+  break;
+```
+
+- [ ] **Step 6: 修改 clearWorld 清除 world_overflow store**
+
+将 `clearWorld()` 函数改为：
+
+```javascript
+function clearWorld() {
+  if (!db) {
+    return Promise.reject(new Error('DB not initialized'));
+  }
+  return new Promise((resolve, reject) => {
+    const tx = db.transaction([WORLD_META_STORE, WORLD_REGION_STORE, WORLD_OVERFLOW_STORE, PERSISTENCE_CONFIG.STORE_NAME], 'readwrite');
+    tx.objectStore(WORLD_META_STORE).clear();
+    tx.objectStore(WORLD_REGION_STORE).clear();
+    tx.objectStore(WORLD_OVERFLOW_STORE).clear();
+    tx.objectStore(PERSISTENCE_CONFIG.STORE_NAME).clear();
+    tx.oncomplete = () => resolve(true);
+    tx.onerror = () => reject(tx.error);
+  });
+}
+```
+
+- [ ] **Step 7: Commit**
+
+```bash
+git add src/constants/PersistenceConfig.js src/workers/PersistenceWorker.js
+git commit -m "feat(persistence): add world_overflow store for cross-region overflow blocks"
+```
+

+
+### Task 2: WorldStore.js — 新增 overflow API 包装方法
+
+**Files:**
+- Modify: `src/world/WorldStore.js`
+
+- [ ] **Step 1: 在 WorldStore 类中新增 saveOverflowBlocks**
+
+在 `clearWorld()` 方法之前（约第 228 行前）添加：
+
+```javascript
+  // ============================================================
+  // Cross-Region Overflow Blocks 读写
+  // ============================================================
+
+  /**
+   * 保存跨 region overflow blocks
+   * @param {number} rx
+   * @param {number} rz
+   * @param {object} overflowData - { "cx,cz": [{x,y,z,type,orientation}, ...] }
+   */
+  async saveOverflowBlocks(rx, rz, overflowData) {
+    const regionKey = this.regionKey(rx, rz);
+    return getPersistenceService().postMessage('saveOverflowBlocks', { regionKey, overflowData });
+  }
+
+  /**
+   * 读取跨 region overflow blocks
+   * @param {number} rx

+  async getOverflowBlocks(rx, rz) {
+    const regionKey = this.regionKey(rx, rz);
+    return getPersistenceService().postMessage('getOverflowBlocks', { regionKey });
+  }
+
+  /**
+   * 删除跨 region overflow blocks
+   * @param {number} rx
+   * @param {number} rz
+   */
+  async removeOverflowBlocks(rx, rz) {
+    const regionKey = this.regionKey(rx, rz);
+    return getPersistenceService().postMessage('removeOverflowBlocks', { regionKey });
+  }
+```
+
+- [ ] **Step 2: Commit**
+
+```bash
+git add src/world/WorldStore.js
+git commit -m "feat(world-store): add cross-region overflow block read/write API"
+```
+
+---
+
+### Task 3: WorldWorker.js — 返回 unresolved overflow blocks 数据
+
+**Files:**
+- Modify: `src/workers/WorldWorker.js`
+
+- [ ] **Step 1: 修改 resolveOverflowWithinRegion 收集 unresolved blocks**
+
+在 `src/workers/WorldWorker.js` 的 `resolveOverflowWithinRegion` 函数中（约第 1307 行），找到 `if (!isInRegion)` 分支（约第 1339 行）。
+
+在该函数顶部（第 1308-1311 行后）新增变量：
+
+```javascript
+  const unresolvedOverflowBlocks = [];
+```
+
+在 `if (!isInRegion)` 分支的 `continue` 之前（约第 1348 行），添加收集逻辑：
+
+```javascript
+      if (!isInRegion) {
+        const blockCount = overflowEntry.blockDataBlocks?.length || 0;
+        unresolved += blockCount;
+        const [sourceCx, sourceCz] = sourceKey.split(',').map(Number);
+        const offsetKey = `${targetCx - sourceCx},${targetCz - sourceCz}`;
+        unresolvedByDistance.set(offsetKey, (unresolvedByDistance.get(offsetKey) || 0) + blockCount);
+        for (const block of (overflowEntry.blockDataBlocks || [])) {
+          unresolvedCoords.add(encodeCoord(block.x, block.y, block.z));
+        }
+        // 收集跨 region overflow 数据用于主线程分发
+        unresolvedOverflowBlocks.push({
+          chunkKey: overflowEntry.chunkKey,
+          blockDataBlocks: overflowEntry.blockDataBlocks || []
+        });
+        continue;
+      }
+```
+
+修改 return 语句（约第 1374 行），新增 `unresolvedOverflowBlocks`：
+
+```javascript
+  return {
+    resolved,
+    unresolved,
+    uniqueUnresolvedCoords: unresolvedCoords.size,
+    topDistanceBuckets: Array.from(unresolvedByDistance.entries())
+      .sort((a, b) => b[1] - a[1])
+      .slice(0, 5)
+      .map(([offset, blocks]) => ({ offset, blocks })),
+    unresolvedOverflowBlocks
+  };
+```
+
+- [ ] **Step 2: 修改 handleRegionGeneration 返回 unresolvedOverflowBlocks**
+
+在 `handleRegionGeneration` 函数中（约第 1390 行），确认 `postMessage` 的数据对象（约第 1431 行）已经通过 `routingDiagnostics` 包含了 `unresolvedOverflowBlocks`。由于 `routingDiagnostics` 已经包含该字段，无需额外修改 `postMessage` 结构。
+
+验证 `postMessage` 调用处：
+
+```javascript
+  postMessage({
+    type: 'regionGenerated',
+    rx, rz,
+    chunks: regionChunks,
+    routingDiagnostics,
+    taskId
+  });
+```
+
+此步骤只需确认 `routingDiagnostics.unresolvedOverflowBlocks` 已存在。
+
+- [ ] **Step 3: Commit**
+
+```bash
+git add src/workers/WorldWorker.js
+git commit -m "feat(world-worker): return unresolved cross-region overflow blocks from region generation"
+```
+
+---
+
+### Task 4: WorldGenerationService.js — 收集、分发、消费 overflow
+
+**Files:**
+- Modify: `src/world/WorldGenerationService.js`
+
+- [ ] **Step 1: 在构造函数中初始化 crossRegionOverflowMap**
+
+在 `constructor` 中（约第 34 行），`this._isGenerating = false` 之后添加：
+
+```javascript
+    this._crossRegionOverflowMap = new Map(); // 暂存跨 region overflow
+```
+
+- [ ] **Step 2: 新增 _collectCrossRegionOverflow 方法**
+
+在 `_generateRegion` 方法之前（约第 216 行前）添加：
+
+```javascript
+  /**
+   * 收集 Worker 返回的跨 region overflow blocks
+   * @param {object} data - Worker 返回的 regionGenerated 数据
+   */
+  _collectCrossRegionOverflow(data) {
+    const overflowBlocks = data.routingDiagnostics?.unresolvedOverflowBlocks || [];
+    for (const entry of overflowBlocks) {

+      }
+      this._crossRegionOverflowMap.get(targetRegionKey).push(entry);
+    }
+  }
+```
+
+- [ ] **Step 3: 新增 _distributeCrossRegionOverflow 方法**
+
+在 `_collectCrossRegionOverflow` 之后添加：
+
+```javascript
+  /**

+
+- [ ] **Step 5: 修改 _generateRegion 回调收集 overflow**
+
+在 `_generateRegion` 的 `workerCallbacks.set` 回调中（约第 222 行），在 `resolve(regionRecord)` 之前添加：
+
+```javascript
+        // 收集跨 region overflow blocks
+        this._collectCrossRegionOverflow(data);
+```
+
+位置应在 `await getWorldStore().saveRegionRecord` 成功之后，`resolve(regionRecord)` 之前。

+
+- [ ] **Step 6: 修改 generateInitialWorld 在全部 region 生成后分发 overflow**
+
+在 `generateInitialWorld` 的双层 for 循环之后（约第 190 行后），更新状态为 `'done'` 之前，添加：
+
+```javascript
+      // 分发跨 region overflow blocks
+      const generatedRegionKeys = [];
+      for (let rx = minRx; rx <= maxRx; rx++) {
+        for (let rz = minRz; rz <= maxRz; rz++) {

+
+- [ ] **Step 7: 修改 expandWorldIfNeeded 消费已持久化的 overflow**
+
+在 `expandWorldIfNeeded` 的 region 生成循环之后（约第 602 行后），更新边界之前，添加：

+# 跨 Region Overflow Block 路由机制设计
+
+日期：2026-04-27
+状态：待实施
+
+## 问题陈述
+
+Region 级 Worker 预生成（`generateRegion`）在单个 Worker 调用内生成 8×8 chunk。`resolveOverflowWithinRegion` 只将 overflow blocks 路由到同 region 内的目标 chunk。**跨 region 的 overflow blocks 被静默丢弃**。
+
+日志数据显示，大量 region 存在严重 unresolved overflow：
+
+- Region `1,0`: 7489 resolved, **20640 unresolved**
+- Region `2,0`: 15172 resolved, **18214 unresolved**
+- Region `2,1`: 13864 resolved, **21611 unresolved**
+
+预生成 49 个 region 的总 unresolved 数量预估超过 **10 万方块**。这些数据丢失导致地图在 region 边界处出现结构断裂（城市、金字塔、树木等被截断）。
+
+## 目标
+
+1. **不丢失任何跨 region overflow block**：所有 overflow 数据都应当被保留并最终路由到正确的 chunk。
+2. **预生成阶段自动补齐**：同一批次预生成的 region 之间，overflow 在生成结束后自动分发。
+3. **扩图阶段自动消费**：持久化的 overflow 在目标 region 被生成（或扩图）时自动合并。
+4. **运行时路径不受影响**：现有 chunk 级运行时加载逻辑保持原样。
+
+## 架构设计
+
+### 数据流概览
+
+```
+Worker 生成 Region A
+  └─ resolveOverflowWithinRegion
+      ├─ 同 region 内 overflow → 直接路由到目标 chunk (已有)
+      └─ 跨 region overflow → 序列化返回 (新增)
+
+主线程 _generateRegion 回调
+  └─ 保存 Region A 的 64 个 chunk 到 WorldStore
+  └─ 收集跨 region overflow → 暂存到 _crossRegionOverflowMap
+
+预生成/扩图批次完成后
+  └─ _distributeCrossRegionOverflow()
+      ├─ 目标 region 已在同批次中 → 直接追加到对应 RegionRecord
+      └─ 目标 region 不在同批次中 → 持久化到 world_overflow store
+
+未来目标 region 被生成/扩图时
+  └─ 从 world_overflow store 读取属于该 region 的方块
+  └─ 合并到 RegionRecord 后删除
+```
+
+### 核心数据结构
+
+**Cross-Region Overflow Block**（Worker 返回，主线程传递）：
+
+```javascript
+{
+  chunkKey: "cx,cz",       // 目标 chunk
+  blockDataBlocks: [       // 需要追加到该 chunk 的方块
+    { x, y, z, type, orientation }
+  ]
+}
+```
+
+**主线程暂存结构**（`WorldGenerationService._crossRegionOverflowMap`）：
+
+```javascript
+// Map<regionKey, Array<{chunkKey, blockDataBlocks}>>
+// regionKey 是目标 region（不是源 region）
+```
+
+**持久化结构**（`world_overflow` IndexedDB store）：
+
+```javascript
+{
+  regionKey: "rx,rz",      // 目标 region
+  data: {
+    "cx,cz": [             // key 为目标 chunkKey
+      { x, y, z, type, orientation }
+    ]
+  },
+  lastModified: timestamp
+}
+```
+
+## 组件改动清单
+
+### 1. `src/workers/WorldWorker.js`
+
+**`resolveOverflowWithinRegion`**（`line 1307`）：
+- 返回对象新增 `unresolvedOverflowBlocks` 字段
+- 将当前丢弃的跨 region overflow 数据收集为数组返回
+
+```javascript
+return {
+  resolved,
+  unresolved,
+  uniqueUnresolvedCoords: unresolvedCoords.size,
+  topDistanceBuckets: [...],
+  unresolvedOverflowBlocks: [...]  // 新增
+};
+```
+
+**`handleRegionGeneration`**（`line 1390`）：
+- `postMessage` 返回数据中包含 `unresolvedOverflowBlocks`
+
+### 2. `src/world/WorldGenerationService.js`
+
+**新增成员**：
+```javascript
+this._crossRegionOverflowMap = new Map(); // 暂存跨 region overflow
+```
+
+**新增方法 `_collectCrossRegionOverflow(data)`**：
+- 在 `_generateRegion` 的 worker 回调中调用
+- 将 `data.unresolvedOverflowBlocks` 按目标 regionKey 分组，存入 `_crossRegionOverflowMap`
+
+**新增方法 `_distributeCrossRegionOverflow(targetRegionKeys)`**：
+- 遍历 `_crossRegionOverflowMap`
+- 对于目标 region 在 `targetRegionKeys` 中的条目：
+  1. 从 WorldStore 加载对应 RegionRecord
+  2. 将 overflow blocks 追加到对应 chunk 的 `blockData`
+  3. 保存回 WorldStore
+  4. 从 map 中删除该条目
+- 剩余的条目（目标 region 不在当前批次）：
+  1. 调用 WorldStore 保存到 `world_overflow` store
+
+**修改 `generateInitialWorld`**：
+- 双层 for 循环生成完所有 region 后，调用 `_distributeCrossRegionOverflow`
+- 传入所有已生成的 region keys
+
+**修改 `expandWorldIfNeeded`**：
+- 生成新 region 后，调用 `_distributeCrossRegionOverflow` 传入新 region keys
+- **新增步骤**：对每个新 region，调用 WorldStore 检查 `world_overflow` 是否有属于它的方块，如果有则合并到 RegionRecord 并删除
+
+### 3. `src/world/WorldStore.js`
+
+**新增方法**：
+
+```javascript
+async saveOverflowBlocks(rx, rz, overflowData) {
+  const regionKey = this.regionKey(rx, rz);
+  return getPersistenceService().postMessage('saveOverflowBlocks', { regionKey, overflowData });
+}
+
+async getOverflowBlocks(rx, rz) {
+  const regionKey = this.regionKey(rx, rz);
+  return getPersistenceService().postMessage('getOverflowBlocks', { regionKey });
+}
+
+async removeOverflowBlocks(rx, rz) {
+  const regionKey = this.regionKey(rx, rz);
+  return getPersistenceService().postMessage('removeOverflowBlocks', { regionKey });
+}
+```
+
+### 4. `src/workers/PersistenceWorker.js`
+
+**新增 object store**：
+- `WORLD_OVERFLOW_STORE = 'world_overflow'`
+- 需要在 `init()` 的升级回调中创建（`keyPath: 'regionKey'`）
+- **DB_VERSION 从 2 升级到 3**
+
+**新增函数**：
+
+```javascript
+function saveOverflowBlocks(regionKey, overflowData) {
+  return performTransaction(db, WORLD_OVERFLOW_STORE, 'readwrite', (store) =>
+    store.put({ regionKey, data: overflowData, lastModified: Date.now() })
+  );
+}
+
+function getOverflowBlocks(regionKey) {
+  return performTransaction(db, WORLD_OVERFLOW_STORE, 'readonly', (store) =>
+    store.get(regionKey)
+  ).then((result) => result ? result.data : null);
+}
+
+function removeOverflowBlocks(regionKey) {
+  return performTransaction(db, WORLD_OVERFLOW_STORE, 'readwrite', (store) =>
+    store.delete(regionKey)
+  );
+}
+```
+
+**修改 `init()`**：
+- 检查并创建 `WORLD_OVERFLOW_STORE`
+- 升级 `PERSISTENCE_CONFIG.DB_VERSION` 到 3
+
+**修改 `clearWorld()`**：
+- 清除 `WORLD_OVERFLOW_STORE`
+
+**修改 `onmessage` switch**：
+- 新增 `saveOverflowBlocks`、`getOverflowBlocks`、`removeOverflowBlocks` case
+
+### 5. `src/constants/PersistenceConfig.js`
+
+**修改 `DB_VERSION`**：
+```javascript
+DB_VERSION: 3, // v3: 新增 world_overflow store（跨 region overflow 持久化）
+```
+
+## 关键算法
+
+### `_collectCrossRegionOverflow(data)`
+
+```javascript
+const overflowBlocks = data.unresolvedOverflowBlocks || [];
+for (const entry of overflowBlocks) {
+  const [targetCx, targetCz] = entry.chunkKey.split(',').map(Number);
+  const { rx: targetRx, rz: targetRz } = this._chunkToRegion(targetCx, targetCz);
+  const targetRegionKey = this._regionKey(targetRx, targetRz);
+
+  if (!this._crossRegionOverflowMap.has(targetRegionKey)) {
+    this._crossRegionOverflowMap.set(targetRegionKey, []);
+  }
+  this._crossRegionOverflowMap.get(targetRegionKey).push(entry);
+}
+```
+
+### `_distributeCrossRegionOverflow(targetRegionKeys)`
+
+```javascript
+const targetKeySet = new Set(targetRegionKeys);
+for (const [regionKey, entries] of this._crossRegionOverflowMap) {
+  if (targetKeySet.has(regionKey)) {
+    // 1. 加载 RegionRecord
+    const [rx, rz] = regionKey.split(',').map(Number);
+    const record = await getWorldStore().getRegionRecord(rx, rz);
+    if (!record) continue;
+
+    // 2. 按 chunkKey 合并到 blockData
+    for (const entry of entries) {
+      const chunkData = record.chunks[entry.chunkKey];
+      if (!chunkData) continue;
+      for (const block of entry.blockDataBlocks) {
+        const code = encodeCoord(block.x, block.y, block.z);
+        if (chunkData.blockData[code] === undefined) {
+          chunkData.blockData[code] = block.orientation
+            ? { type: block.type, orientation: block.orientation }
+            : block.type;
+        }
+      }
+    }
+
+    // 3. 保存
+    await getWorldStore().saveRegionRecord(rx, rz, record);
+    this._crossRegionOverflowMap.delete(regionKey);
+  }
+}
+
+// 剩余条目持久化
+for (const [regionKey, entries] of this._crossRegionOverflowMap) {
+  const [rx, rz] = regionKey.split(',').map(Number);
+  const overflowData = {};
+  for (const entry of entries) {
+    if (!overflowData[entry.chunkKey]) overflowData[entry.chunkKey] = [];
+    overflowData[entry.chunkKey].push(...entry.blockDataBlocks);
+  }
+  await getWorldStore().saveOverflowBlocks(rx, rz, overflowData);
+  this._crossRegionOverflowMap.delete(regionKey);
+}
+```
+
+### 扩图时的 Overflow 消费
+
+```javascript
+async _consumeOverflowForRegion(rx, rz) {
+  const overflowData = await getWorldStore().getOverflowBlocks(rx, rz);
+  if (!overflowData) return;
+
+  const record = await getWorldStore().getRegionRecord(rx, rz);
+  if (!record) return;
+
+  for (const [chunkKey, blocks] of Object.entries(overflowData)) {
+    const chunkData = record.chunks[chunkKey];
+    if (!chunkData) continue;
+    for (const block of blocks) {
+      const code = encodeCoord(block.x, block.y, block.z);
+      if (chunkData.blockData[code] === undefined) {
+        chunkData.blockData[code] = block.orientation
+          ? { type: block.type, orientation: block.orientation }
+          : block.type;
+      }
+    }
+  }
+
+  await getWorldStore().saveRegionRecord(rx, rz, record);
+  await getWorldStore().removeOverflowBlocks(rx, rz);
+}
+```
+
+## 错误处理
+
+| 场景 | 处理策略 |
+|------|----------|
+| 目标 RegionRecord 不存在 | 跳过该 region 的分发，将 overflow 持久化到 world_overflow（等待目标 region 被生成） |
+| 目标 chunk 在 RegionRecord 中不存在 | 跳过该 chunk 的方块（说明 chunk 可能未生成，持久化等待） |
+| 方块坐标已被占用 | 跳过该方块（保留已有数据，不覆盖） |
+| IndexedDB 写入失败 | 输出错误日志，不中断流程，overflow 保留在内存 map 中等待下次重试 |
+| DB 升级失败（v2→v3） | 在 `init()` 中捕获并输出错误，回退到不持久化 overflow（内存-only 模式） |
+
+## 测试策略
+
+1. **单元测试**：`_collectCrossRegionOverflow` 和 `_distributeCrossRegionOverflow` 的分组/合并逻辑
+2. **集成测试**：预生成 3×3 region，在边界放置一个跨越 4 个 region 的大型结构，验证所有 overflow block 最终都在正确的 chunk 中
+3. **持久化测试**：预生成后清除内存，重新加载 region record，验证 overflow blocks 已正确合并
+4. **扩图测试**：预生成小范围后扩图，验证之前持久化的 overflow 被正确消费
+
+## 向后兼容
+
+| 路径 | 影响 |
+|------|------|
+| 运行时 chunk 加载 | 无影响，继续使用现有 `_mergeOverflowBlocks` 路径 |
+| 旧存档（DB v2） | 打开时自动升级至 v3，`world_overflow` store 为空，不影响已有数据 |
+| `clearWorld` | 新增清除 `world_overflow`，不影响业务逻辑 |
+| Region 级生成 Worker | 仅新增 `unresolvedOverflowBlocks` 返回字段，主线程旧代码可忽略 |
+
+## 风险与缓解
+
+| 风险 | 缓解 |
+|------|------|
+| 跨 region overflow 数据量过大，内存占用激增 | `_crossRegionOverflowMap` 在分发后立即清空；单个 region 的 overflow 数据通常 < 50KB |
+| 扩图时消费 overflow 与 region 生成产生竞态 | `expandWorldIfNeeded` 串行执行，先 `_generateRegion` 再 `_consumeOverflowForRegion` |
+| DB v3 升级时浏览器已有旧 tab 打开 v2 DB | `init()` 中检测 store 缺失则关闭重连，触发升级 |
+| 持久化 overflow 长期累积无人消费 | 日志输出未消费 overflow 的统计；未来可考虑定期清理 |

-实体的实现。不要吧空岛当做大型实体来处理，就当成小实体来处理即可，这样最简单。  
-
-⏺ 我来按照系统化调试流程调查空岛被切割的问题。
-
-  Phase 1: Root Cause Investigation
-
-  首先，让我查看空岛生成代码和 House 实体的实现，理解两者的差异。
-
-  Searched for 3 patterns, read 4 files (ctrl+o to expand)
-
-⏺ 现在让我查看 WorldWorker.js 中关于结构中心和跨 Chunk 渲染的关键逻辑。
-
-  Searched for 5 patterns, read 3 files (ctrl+o to expand)
-
-⏺ 找到根本原因了！
-
-  在 WorldWorker.js 第 1455 行：
-  structureCenters.length = 0;  // 清空了 structureCenters 数组
-
-  然后在第 1456-1459 行，只从 structureQueueWithCenters 中重建结构中心：
-  structureQueueWithCenters.forEach(({ centerX, centerY, centerZ, type }) => {
-    if (!type || centerX === undefined) return;
-    pushStructureCenter({ type, x: centerX, y: centerY, z: centerZ });
-  });
-
-  问题：空岛和云朵的结构中心被添加到 structureCenters 
-  后，在后续处理中被清空了，而且它们没有被加入 
-  structureQueue，所以重建时丢失了！
-
-  让我确认一下云朵和空岛确实没有进入 structureQueue。
-
-  Searched for 1 pattern (ctrl+o to expand)
-
-⏺ 确认问题！现在让我制定修复方案。
-
-  Phase 2: Pattern Analysis
-
-  让我对比 House 实体的处理方式：
-
-  Searched for 4 patterns (ctrl+o to expand)
-
-⏺ Phase 3: Hypothesis and Testing
-
-  假设： 空岛和云朵的结构中心被添加到 structureCenters 后，在
-  structureCenters.length = 0 时被清空，且由于它们没有进入
-  structureQueue，重建时丢失。
-
-  验证： 让我创建一个简单的修复：在清空 structureCenters
-  之前，先保存空岛和云朵的结构中心，重建后再添加回去。

-⏺ 修复完成
-
-  根本原因： 在 WorldWorker.js 中，空岛和云朵的结构中心被直接添加到
-  structureCenters 数组，但随后在第 1455 行 structureCenters.length = 0
-  被清空。重建时只从 structureQueueWithCenters 中恢复，而空岛和云朵没有进入
-  structureQueue，导致它们的结构中心丢失。
-
-  修复方案： 在清空 structureCenters
-  之前，先保存空岛和云朵的结构中心，然后在重建完成后恢复它们：
-
-  // 保存空岛和云朵的结构中心（这些不是通过 structureQueue 生成的）
-  const islandAndCloudCenters = structureCenters.filter(c => c.type === 'island'
-   || c.type === 'cloud');
-
-  // 重建当前队列生成出的结构中心（去重）
-  structureCenters.length = 0;
-  // ... 重建代码 ...
-
-  // 恢复空岛和云朵的结构中心
-  islandAndCloudCenters.forEach(center => pushStructureCenter(center));
-
-  按照用户要求，空岛和云朵被当作小实体处理（类似 House），通过
-  CROSS_CHUNK_OWNER_TYPES 中的配置和 crossChunkDist 渲染距离来实现跨 Chunk
-  渲染，而不是作为大型静态结构进入 structureQueue。

-⏺ 修复完成
-
-  根本原因：
-  当新 chunk 生成时，Worker 不知道相邻 chunk
-  中已有空岛/云朵的结构中心，因此无法正确判断跨越边界到新 chunk
-  的方块是否属于空岛/云朵。
-
-  修复方案：
-
-  1. src/world/ChunkGenerator.js
-
-  在发送生成请求给 Worker 之前，收集相邻已加载 chunk 的 structureCenters
-  并传递：
-
-  // 收集相邻已加载 chunk 的 structureCenters
-  const neighborStructureCenters = [];
-  if (this.world?.chunks) {
-    for (let dx = -1; dx <= 1; dx++) {
-      for (let dz = -1; dz <= 1; dz++) {
-        if (dx === 0 && dz === 0) continue;
-        const neighborKey = `${this.cx + dx},${this.cz + dz}`;
-        const neighborChunk = this.world.chunks.get(neighborKey);
-        if (neighborChunk?.structureCenters?.length) {
-          neighborStructureCenters.push(...neighborChunk.structureCenters);
-        }
-      }
-    }

-    seed: WORLD_CONFIG.SEED,
-    snapshot,
-    structureCenters: neighborStructureCenters.length > 0 ?
-  neighborStructureCenters : undefined
-  });
-
-  2. src/workers/WorldWorker.js（之前已修复）
-
-  - 保存空岛和云朵的结构中心，防止在重建时被清空
-  - 恢复空岛和云朵的结构中心到 structureCenters
-
-  现在当新 chunk 生成时，Worker
-  能正确识别属于相邻空岛/云朵的方块，避免切割问题。

-
-⏺ 修复完成
-
-  根本原因：
-  1. 空岛/云朵生成时没有设置 activeStructureType，导致 blockSourceTypeMap
-  没有记录这些方块
-  2. isBlockOwnedByCurrentChunk 只检查 blockSourceTypeMap，对于新 chunk
-  中属于相邻空岛的方块无法识别
-
-  修复方案：
-
-  1. src/workers/WorldWorker.js - 设置 activeStructureType
-
-  activeStructureType = 'island';
-  Island.generate(centerWx, islandY, centerWz, fakeChunk, dPlaceholder);
-  activeStructureType = null;
-
-  2. src/workers/WorldWorker.js - 修改归属判断逻辑
-
-  对于没有 sourceType 的方块，也直接检查是否属于跨 chunk 结构：
-  // 对于没有 sourceType 的方块，直接检查是否属于跨 Chunk 结构
-  return belongsToCrossChunkStructure(block.x, block.y, block.z);
-
-  3. src/world/ChunkGenerator.js（之前修复）
-
-  收集相邻 chunk 的 structureCenters 传递给 Worker。
-
-  现在新 chunk 生成时会：
-  1. 接收相邻 chunk 传来的空岛 structureCenters
-  2. 对于边界处的方块，直接根据 structureCenters 判断是否属于空岛
-  3. 空岛方块会被正确归属到当前 chunk，避免切割

-  问题现象
-
-  删除方块时，有两个面没有立即补面，1 秒后（Consolidation 完成）才补面。
-
-  代码逻辑分析
-
-  _revealNeighbors 逻辑（671-675 行）：
-  if (!this.visibleKeys.has(nKey) && props.isRendered !== false) {
-    this._refreshBlockRenderMesh(nx, ny, nz, nKey, entry);  // 情况 A: 
-  创建动态网格
-  } else if (this.visibleKeys.has(nKey)) {
-    this._refreshBlockRenderLightweight(nx, ny, nz, nKey, entry);  // 情况 B: 
-  轻量刷新
-  }
-
-  _refreshBlockRenderLightweight 逻辑（634-639 行）：
-  if (this.visibleKeys.has(key) && !this.dynamicMeshes.has(key)) {
-    if (this._updateRenderedBlockFaceMask(x, y, z, key, type)) return;  // 
-  尝试更新 faceMask
-  }
-  // 兜底：回退到重建
-  this._refreshBlockRenderMesh(x, y, z, key, entryOrType);
-
-  _updateRenderedBlockFaceMask 逻辑（583-614 行）：
-  1. 先尝试从 dynamicMeshes 获取（593-600 行）
-  2. 再尝试从 instanceIndexMap + InstancedMesh 获取（602-614 行）
-  3. 失败条件：
-    - dynamicMeshes 中没有该 key（594 行判断）
-    - instanceIndexMap[type] 中没有该 key（603-604 行）
-    - InstancedMesh 不存在或 faceMaskAttr 不存在（606-610 行）
-
-  问题根因
-
-  当邻居方块处于以下状态时，补面会失败：
-  1. 邻居方块在 visibleKeys 中（Worker 认为它有可见面）
-  2. 但邻居方块不在 instanceIndexMap 中（因为它在 InstancedMesh 中没有条目）
-  3. 也不在 dynamicMeshes 中（不是动态创建的）
-
-  这种情况发生在：
-  - Worker 生成 chunk 时，某些方块被判定为"部分可见"并加入 visibleKeys
-  - 但这些方块在 allBlockTypes 中有数据，却没在 instanceIndexMap 中注册
-  - 或者 instanceIndexMap 的注册逻辑有遗漏

-  Searched for 2 patterns, read 1 file (ctrl+o to expand)
-
-⏺ Phase 1: 根因分析完成
-
-  我找到了问题的根因！
-
-  数据流追踪
-
-  WorldWorker 中（1685-1697 行）：
-  if (shouldRender && visible) {
-    // ... 计算 AO
-    d[block.type].push({x, y, z, aoLow, aoHigh, faceMask, orientation});
-    visibleKeys.push(key);  // ← visibleKeys 只包含 shouldRender && visible 
-  的方块
-  }
-
-  buildMeshData 中（189-221 行）：
-  for (const type in d) {  // ← 只遍历 d 中的类型
-    const positions = d[type];
-    // ...
-    for (let i = 0; i < count; i++) {
-      const pos = positions[i];
-      const posKey = `${pos.x},${pos.y},${pos.z}`;
-      instanceIndexMap[posKey] = i;  // ← instanceIndexMap 只包含 d 中的方块
-    }
-  }
-
-  问题根因
-
-  visibleKeys 和 instanceIndexMap 的生成条件不一致：
-
-  1. visibleKeys 包含所有 shouldRender && visible 的方块
-  2. instanceIndexMap 只包含 d[block.type] 中的方块（即实际添加到 InstancedMesh
-  的方块）
-  3. 问题场景：当 props.isRendered === false 时，方块满足：
-    - shouldRender && visible === true → 加入 visibleKeys
-    - 但在 buildMeshes 中被跳过（if (!props.isRendered || count === 0) 
-  continue;）→ 不加入 instanceIndexMap
-
-  这就导致了：
-  - 某些方块在 visibleKeys 中（Worker 认为它可见）
-  - 但不在 instanceIndexMap 中（因为 isRendered === false 或 count === 0）
-  - 当删除邻居方块时，_revealNeighbors 调用 _refreshBlockRenderLightweight
-  - _updateRenderedBlockFaceMask 失败（因为找不到实例网格）
-  - 虽然有回退到 _refreshBlockRenderMesh，但可能存在时序问题
-
-  假设
-
-  Hypothesis: 当 _updateRenderedBlockFaceMask 返回 false
-  时，_refreshBlockRenderLightweight 应该会回退到
-  _refreshBlockRenderMesh。但问题可能出在：
-
-  1. 回退逻辑存在但没有执行：_refreshBlockRenderLightweight 被调用时，可能因为
-  !this.visibleKeys.has(key) 条件不满足而跳过
-  2. 或者 _revealNeighbors 中的判断逻辑有问题：当方块在 visibleKeys
-  中但实际应该被回退时，没有正确回退
-
-  让我验证回退逻辑是否真正执行：
-
-  Read 1 file (ctrl+o to expand)
-
-⏺ Phase 2: 模式分析
-
-  我发现了！问题在于 _refreshBlockRenderLightweight 第 632 行：
-
-  if (!props.isRendered) return;
-
-  当 props.isRendered === false 时，函数直接返回，不会执行到第 639 
-  行的回退逻辑！
-
-  这意味着：
-  1. _revealNeighbors 调用 _refreshBlockRenderLightweight（因为
-  visibleKeys.has(nKey) === true）
-  2. _refreshBlockRenderLightweight 检查 props.isRendered，如果为 false
-  则直接返回
-  3. 回退逻辑永远不会执行
-  4. 方块没有补面，直到 Consolidation 后全量重建
-
-  但这还不是全部问题。让我再检查 _revealNeighbors 的判断逻辑：
-
-  if (!this.visibleKeys.has(nKey) && props.isRendered !== false) {
-    this._refreshBlockRenderMesh(nx, ny, nz, nKey, entry);  // 情况 A
-  } else if (this.visibleKeys.has(nKey)) {
-    this._refreshBlockRenderLightweight(nx, ny, nz, nKey, entry);  // 情况 B
-  }
-
-  问题分析：
-  - 当 visibleKeys.has(nKey) === true 且 props.isRendered === false 时：
-    - 情况 A 不满足（因为 visibleKeys.has(nKey) === true）
-    - 情况 B 满足，调用 _refreshBlockRenderLightweight
-    - 但 _refreshBlockRenderLightweight 在第 632 行直接返回
-    - 没有补面发生
-
-  Phase 3: 假设与验证
-
-  根因假设：
-  1. Worker 生成 visibleKeys 时，某些方块的 props.isRendered === false
-  但仍然被加入 visibleKeys（因为 visible 判定和 isRendered 判定是分开的）
-  2. 主线程 buildMeshes 时，这些方块因为 isRendered === false 被跳过，不加入
-  instanceIndexMap
-  3. 删除邻居时，_revealNeighbors 错误地调用了 _refreshBlockRenderLightweight
-  4. _refreshBlockRenderLightweight 因为 isRendered === false 直接返回，不回退
-
-  验证方法：检查 Worker 中 visibleKeys 的生成逻辑是否应该过滤 isRendered === 
-  false 的方块。
-
-  Read 1 file (ctrl+o to expand)
-
-⏺ 我找到了！在 WorldWorker 的第 1685-1698 行：
-
-  if (shouldRender && visible) {
-    // ...
-    d[block.type].push(...);
-    visibleKeys.push(key);  // ← 没有检查 props.isRendered
-  }
-
-  问题：Worker 中没有检查 props.isRendered，所以 isRendered === false
-  的方块也可能被加入 visibleKeys 和 d[block.type]。
-
-  但在主线程的 buildMeshes 中（ChunkGenerator.js 第 110 行）：
-  if (!props.isRendered || count === 0) continue;  // ← 跳过 isRendered === 
-  false 的方块
-
-  这导致了数据不一致。
-
-  Phase 4: 实现修复
-
-  修复方案：在 WorldWorker 的 visibleKeys 生成逻辑中，添加 props.isRendered !== 
-  false 的检查，确保只有真正会被渲染的方块才会被加入 visibleKeys。
-
-⏺ 好的，任务已经存在。现在让我实施修复：
-
-  修复方案：在 WorldWorker 中添加 props.isRendered !== false 检查，确保
-  visibleKeys 只包含真正会被渲染的方块。

-
-  问题根因
-
-  补面缺失 bug的根本原因是 visibleKeys 和 instanceIndexMap 的数据不一致：
-
-  1. Worker 生成 visibleKeys 时（WorldWorker.js 第 1685-1702 行）：
-    - 只检查 shouldRender && visible
-    - 没有检查 props.isRendered !== false
-    - 导致 isRendered === false 的方块也被加入 visibleKeys
-  2. 主线程构建 instanceIndexMap 时（ChunkGenerator.js 第 110 行）：
-    - if (!props.isRendered || count === 0) continue;
-    - 跳过 isRendered === false 的方块
-    - 这些方块不会加入 instanceIndexMap
-  3. 删除方块触发补面时（Chunk.js 第 671-675 行）：
-    - 当 visibleKeys.has(nKey) === true 时调用 _refreshBlockRenderLightweight
-    - 但 _refreshBlockRenderLightweight 在第 632 行检查 if (!props.isRendered) 
-  return;
-    - 直接返回，不执行第 639 行的回退逻辑
-    - 导致补面失败，只能等待 1 秒后 Consolidation 全量重建
-
-  修复方案
-
-  在 WorldWorker.js 的 visibleKeys 生成逻辑中添加 isRendered
-  检查，确保只有真正会被渲染的方块才会被加入 visibleKeys：
-
-  if (shouldRender && visible) {
-    const props = getBlockProperties(block.type);
-    // 只渲染可渲染的方块，避免 visibleKeys 和 instanceIndexMap 不一致
-    if (props.isRendered === false) {
-      continue;
-    }
-    // ... 继续处理
-  }
-
-  验证
-
-  - Lint 检查通过，无新增错误
-  - 修改后的代码确保 visibleKeys 与主线程 buildMeshes 的过滤逻辑保持一致

-
-⏺ Phase 1: 根因调查
-
-  让我添加诊断日志来收集证据，确定补面失效的具体位置。首先，我需要理解完整的删除
-  方块流程：
-
-  Searched for 1 pattern, read 1 file (ctrl+o to expand)
-
-⏺ 让我查看 addBlockDynamic 的完整流程：
-
-  Searched for 1 pattern, read 1 file (ctrl+o to expand)
-
-⏺ 现在我看到了关键流程。删除方块时（第 1654-1667 行）：
-  1. 调用 _revealNeighbors(x, y, z) 唤醒邻居
-  2. 然后 return，不执行后面的创建动态网格逻辑
-
-  让我再次检查 _revealNeighbors 和它调用的函数：
-
-  Read 1 file (ctrl+o to expand)
-
-⏺ 我发现了问题！在 _revealNeighbors 的第 671-675 行：
-
-  if (!this.visibleKeys.has(nKey) && props.isRendered !== false) {
-    this._refreshBlockRenderMesh(nx, ny, nz, nKey, entry);  // 情况 A: 
-  创建动态网格
-  } else if (this.visibleKeys.has(nKey)) {
-    this._refreshBlockRenderLightweight(nx, ny, nz, nKey, entry);  // 情况 B: 
-  轻量刷新
-  }
-
-  问题：当 visibleKeys.has(nKey) === false 但 props.isRendered === false 时：
-  - 情况 A 不满足（因为 props.isRendered === false）
-  - 情况 B 也不满足（因为 visibleKeys.has(nKey) === false）
-  - 没有任何操作被执行！
-
-  这意味着某些方块被完全忽略了。但我之前修复了 WorldWorker 中的 visibleKeys
-  生成逻辑，理论上应该解决了这个问题。
-
-  让我检查一下是否有其他路径会导致 visibleKeys 和 blockData 不一致。让我查看
-  checkReveal 函数：
-
-  Searched for 1 pattern, read 1 file (ctrl+o to expand)
-⏺ 现在我发现了一个重要问题！checkReveal 中第 1790-1791 行：
-
-  if (props.isRendered !== false) {
-    targetChunk._refreshBlockRenderMesh(x, y, z, blockKey, entry);
-  }
-
-  这里检查了 isRendered !== false，但是在 _revealNeighbors 中的情况 A
-  没有这个检查。
-
-  让我仔细分析两种情况：
-
-  情况 A（本 Chunk 内邻居）：第 671-672 行
-  if (!this.visibleKeys.has(nKey) && props.isRendered !== false) {
-    this._refreshBlockRenderMesh(nx, ny, nz, nKey, entry);
-  }
-  - 当 !visibleKeys.has(nKey) 且 props.isRendered !== false 时，创建动态网格
-
-  情况 B（本 Chunk 内邻居）：第 673-674 行
-  else if (this.visibleKeys.has(nKey)) {
-    this._refreshBlockRenderLightweight(nx, ny, nz, nKey, entry);
-  }
-  - 当 visibleKeys.has(nKey) 时，调用轻量刷新
-  - 但没有检查 props.isRendered
-
-  让我添加诊断日志来追踪问题：
-
-⏺ 让我仔细分析视频中描述的现象："删除了一个方块，然后有两个面没有补面，1
-  秒后补面"。
-
-  这说明补面逻辑确实触发了，但是延迟了 1 秒（Consolidation 时间）。这意味着
-  _revealNeighbors 中的逻辑没有立即生效。
-
-  让我检查 _refreshBlockRenderLightweight 是否有问题：
-
-  Read 1 file (ctrl+o to expand)
-
-⏺ 现在我看到了！问题可能在第 634-636 行：
-
-  if (this.visibleKeys.has(key) && !this.dynamicMeshes.has(key)) {
-    if (this._updateRenderedBlockFaceMask(x, y, z, key, type)) return;
-  }
-
-  关键问题：当 _updateRenderedBlockFaceMask 返回 false 时，代码会继续执行到第
-  639 行的回退逻辑。但是，如果回退逻辑执行了，为什么补面还会失败？
-
-  让我检查 _refreshBlockRenderMesh 是否有什么问题：
-
-  Read 1 file (ctrl+o to expand)
-
-⏺ 让我检查 _removeInstancedMeshBlock 是否有问题：

-
-⏺ 我发现了两个关键问题：
-
-  问题分析
-
-  问题 1：options is not defined 错误（致命）
-
-  在 _createDynamicBlockMesh 函数中引用了未定义的 options 变量。这导致回退到
-  _refreshBlockRenderMesh 时抛出异常，补面失败。
-
-  问题 2：cloud 方块的 _updateRenderedBlockFaceMask 失败
-
-  日志显示：
-  [_refreshBlockRenderLightweight] 246,55,112 cloud
-  [_refreshBlockRenderLightweight] _updateRenderedBlockFaceMask failed, fallback
-   to _refreshBlockRenderMesh
-
-  cloud 方块调用 _updateRenderedBlockFaceMask 失败，然后回退到
-  _refreshBlockRenderMesh，但因为问题 1 的错误而崩溃。
-
-  让我先修复问题 1：
-
-  Read 1 file (ctrl+o to expand)
-
-⏺ 我看到了问题！第 1022 行使用了 options.applyAO，但函数签名中没有 options
-  参数。让我查看完整的函数签名：
-
-  Read 1 file (ctrl+o to expand)
-
-⏺ Bash(node -e "
-      const fs = require('fs');…)
-  ⎿    _createDynamicBlockMesh(x, y, z, key, type, orientation) {
-         const props = getBlockProps(type);
-         if (!props.isRendered || !this._isBlockVisibleByKey(key)) {
-     … +7 lines (ctrl+o to expand)
-⏺ 问题找到了！第 1022 行 const applyAO = options.applyAO === true; 中的 options
-  未定义。这是之前重构时遗留的代码。
-
-  根据之前的摘要，applyAO 参数已经被移除了，AO 应该始终计算。让我修复这个问题：
-
-⏺ Update(src/world/Chunk.js)
-  ⎿  Removed 1 line
-      1019      if (!props.isRendered || !this._isBlockVisibleByKey(key))
-             {
-      1020        return null;
-      1021      }
-      1022 -    const applyAO = options.applyAO === true;                
-      1022  
-      1023      const geometry = geomMap[props.geometryType] || geomMap['
-            default'];
-      1024      let material = getMaterials().getMaterial(type);
-
-⏺ 现在让我运行 lint 检查：
-
-⏺ Bash(npm run lint 2>&1 | head -30)
-  ⎿  > mc-lite@1.0.0 lint
-     > eslint src/**/*.js
-     … +24 lines (ctrl+o to expand)
-  ⎿  Found 1 new diagnostic issue in 1 file (ctrl+o to expand)
-
-⏺ 好的，options is not defined 的错误已修复。现在请你：
-
-  1. 刷新页面（或重新启动 npm run start）
-  2. 再次测试删除方块
-  3. 观察补面是否立即生效
-
-  如果补面缺失的问题仍然存在，请发送新的日志给我。
-
-  另外，我注意到日志中有很多重复的 updated faceMask
-  调用（同一个坐标被多次更新），这可能表示存在性能问题，但与补面缺失 bug 无关。
-
-✻ Brewed for 1m 8s
-
-❯ 及时补面的问题依然存在，删除方块后，补面不及时。                              
-
-⏺ 让我继续深入调查。我需要添加更多诊断日志来追踪补面的完整流程：
-
-  Read 1 file (ctrl+o to expand)
-
-⏺ Update(src/world/Chunk.js)
-  ⎿  Error editing file
-
-⏺ Bash(node -e "
-      const fs = require('fs');…)
-  ⎿  Current code:
-       _refreshBlockRenderMesh(x, y, z, key, entryOrType) {
-         const parsed = parseBlockEntry(entryOrType);
-     … +20 lines (ctrl+o to expand)
-
-⏺ Bash(node -e "
-      const fs = require('fs');…)
-  ⎿  修改成功
-
-⏺ 现在让我检查 scheduleConsolidation 的时序，看看是否 consolidation
-  在补面之前就执行了：
-
-  Searched for 4 patterns (ctrl+o to expand)
-
-⏺ Bash(node -e "
-      const fs = require('fs');…)
-  ⎿  (No output)
-
-  Searched for 4 patterns (ctrl+o to expand)
-⏺ 我发现了关键问题！CONSOLIDATION_DELAY = 1000 毫秒（1 秒），这正是用户描述的"1
-  秒后补面"的时间！
-
-  但更重要的是，我需要理解为什么 _revealNeighbors
-  创建的动态网格会被覆盖。让我检查 _isBlockVisibleByKey 函数：
-
-  Searched for 1 pattern (ctrl+o to expand)
-
-⏺ 现在我理解问题了。让我添加更多日志来追踪 consolidation
-  是否在补面后覆盖了动态网格：
-
-⏺ Bash(node -e "
-      const fs = require('fs');…)
-  ⎿  修改成功 - consolidate START
-
-⏺ Bash(node -e "
-      const fs = require('fs');…)
-  ⎿  未找到 buildMeshes 调用
-     Found at line 319
-     319   Chunk.prototype.consolidate = async function() {
-     … +22 lines (ctrl+o to expand)
-
-⏺ Bash(node -e "
-      const fs = require('fs');…)
-  ⎿  修改成功 - _applyConsolidateResult START
-
-  Searched for 2 patterns, read 1 file (ctrl+o to expand)
-
-⏺ 现在请你：
-
-  1. 刷新页面
-  2. 再次测试删除方块
-  3. 观察控制台日志
-
-  你应该看到类似这样的日志序列：
-  [revealNeighbors] <x> <y> <z> [...]
-  [_refreshBlockRenderLightweight] <key> <type> {...}
-  [_refreshBlockRenderMesh] START <key> <type>
-  [_refreshBlockRenderMesh] SUCCESS <key> <type> {...}
-
-  以及 1 秒后：
-  [consolidate] START <cx> <cz> {...}
-  [_applyConsolidateResult] START <cx> <cz> {...}
-
-  关键观察点：
-  1. _revealNeighbors 是否被调用？
-  2. _refreshBlockRenderMesh 是否被调用并成功？
-  3. 如果 _refreshBlockRenderMesh 成功了，为什么补面还是不及时？
-
-  请把完整的日志发给我，特别是包含 [_refreshBlockRenderMesh] 的日志。

-⏺ JSON 解析错误，说明共享内存中读取的 blockData
-  是空的或者格式不正确。问题可能是主线程写入的数据和 Worker 读取的数据不同步。
-
-  让我检查主线程（Chunk.js）发送数据和 Worker（AOWorker.js）接收的逻辑：
-
-  Read 1 file (ctrl+o to expand)
-
-⏺ 我看到问题了。主线程发送的 neighborOffsets 和 neighborSizes 使用的是
-  ${neighbor.cx},${neighbor.cz} 作为键，但 AOWorker
-  中读取时也是用同样的格式。让我检查 AOWorker 的读取逻辑：
-
-  Read 1 file (ctrl+o to expand)
-
-⏺ 问题找到了！错误是 Unexpected end of JSON input，这意味着
-  readBlockDataFromSharedMemory 读取到的字节是空的或者长度为 0。
-
-  让我添加调试日志来检查共享内存中实际写入的数据：

-⏺ 现在让我检查共享内存池的实现，看看 allocate 方法是否正确返回了分配对象：
-
-  Read 1 file (ctrl+o to expand)
-
-⏺ SharedMemoryPool 看起来是正确的。问题可能在于 Chunk.js 中 _executeAORefresh
-  被调用时，getSharedMemoryPool() 返回的是一个 Promise，而虽然我们现在 await
-  了它，但可能在共享内存初始化完成之前就开始调用了。
-
-  让我检查一下 Chunk.js 中如何调用 _executeAORefresh
-  的上下文，以及共享内存初始化的时机：
-  Read 1 file (ctrl+o to expand)
-
-⏺ 让我查看 ChunkConsolidation.js
-  中的共享内存初始化逻辑，确认共享内存是否正确初始化并传递给 Worker：
-
-  Searched for 1 pattern, read 1 file (ctrl+o to expand)
-
-⏺ 我发现问题了！initSharedMemoryForWorkers 函数在第 54-57 行将
-  sharedMemoryPool.buffer 通过 postMessage 发送给 Worker，并且使用了传输列表
-  [sharedMemoryPool.buffer]。
-
-  关键问题：当你将 SharedArrayBuffer
-  放入传输列表时，它的所有权会被转移，主线程将不再拥有对该缓冲区的访问权！
-
-  这就是为什么 Worker 无法解析 JSON - 因为共享内存已经被转移给 Worker，主线程的
-  sharedMemoryPool.buffer 变成了空壳。
-
-  解决方案是不要使用传输列表发送 SharedArrayBuffer，因为它本身就是可共享的（不是
-  可转移的）。让我检查一下这个假设是否正确：
-
-  Read 1 file (ctrl+o to expand)
-
-⏺ 找到问题了！第 51 行和第 57 行的传输列表 [sharedMemoryPool.buffer]
-  是错误的。`SharedArrayBuffer不能被转移（transferable），它设计用于共享。
-
-  当我们把 SharedArrayBuffer 放入传输列表时，会发生以下情况：
-  1. 主线程的缓冲区引用被清空（buffer.byteLength 变为 0）
-  2. Worker 获得唯一的访问权
-  3. 主线程后续尝试访问 sharedMemoryPool.buffer 时，会访问一个空的缓冲区
-
-  修复方法：移除传输列表，因为 SharedArrayBuffer 不需要转移，它是可共享的。

-⏺ 修复完成，0 错误。现在浏览器应该会自动刷新并测试修复。
-
-  修复总结：
-  1. Chunk.js:853 - 添加了 await 到 getSharedMemoryPool() 调用
-  2. ChunkConsolidation.js:51,57 - 移除了传输列表
-  [sharedMemoryPool.buffer]，因为 SharedArrayBuffer
-  是可共享的，不需要也不能被转移
-  3. AOWorker.js:31-38 - 添加了调试日志和空数据保护
-  4. Chunk.js:893 - 添加了调试日志
-
-  现在刷新浏览器测试修复是否生效。

-  2. ChunkConsolidation.js:51,57 - 移除传输列表，SharedArrayBuffer
-  不需要也不能被转移
-  3. SharedMemoryPool.js:36-58 - 所有分配按 4 字节对齐，支持 Float32Array
-  直接访问
-  4. AOWorker.js:31-57 - TextDecoder
-  不能直接解码共享内存视图，先复制到非共享缓冲区；Float32Array 偏移量非 4
-  倍数时创建副本
-
-  刷新浏览器测试修复效果。

-⏺ 还有结果缓冲区的对齐问题。让我读取 AOWorker.js 第 167 行的代码并修复：
-
-  Read 1 file (ctrl+o to expand)
-
-⏺ 问题是 resultBufferOffset 可能不是 4 的倍数，因为 uint8 分配虽然填充了 4
-  字节，但下一个分配的起始位置可能不对齐。让我检查 Chunk.js
-  中分配结果缓冲区的代码：
-
-  Read 1 file (ctrl+o to expand)
-
-⏺ 问题找到了！sharedMemoryPool.allocate 现在会进行 4 字节对齐，但问题是 uint8
-  分配后，下一个 int32 分配的偏移量可能不是 4 的倍数。
-
-  让我检查 SharedMemoryPool 的 allocate 函数：
-
-  Read 1 file (ctrl+o to expand)
-
-⏺ SharedMemoryPool 的对齐逻辑是正确的（每次分配前填充到 4 字节边界）。但问题是
-  AOWorker 中直接使用 resultBufferOffset 创建 Int32Array 时，这个偏移量已经是 4
-  的倍数了（因为共享内存池保证了对齐）。
-
-  让我再仔细看错误 - 问题可能是 resultBufferOffset
-  是从主线程传递过来的，但在传递过程中没有问题。让我检查一下 AOWorker
-  中是否还有其他地方需要处理对齐：
-
-  实际上，问题在于 Worker 端的 sharedBuffer 
-  是传输过来的，可能已经失效了。让我检查 AOWorker 是否正确附加了共享内存：
-
-  Read 1 file (ctrl+o to expand)
-
-⏺ 问题找到了！sharedBuffer 被正确附加了。但是 resultBufferOffset
-  是由主线程传递过来的，我需要确保在 AOWorker 端使用这个偏移量时它是 4 的倍数。
-
-  让我添加调试日志来检查实际传递的偏移量：

-⏺ 现在还需要处理 AOWorker 中其他地方的 TypedArray 创建。让我检查第 35 行和第 56
-  行的错误：
-
-  Read 1 file (ctrl+o to expand)
-
-⏺ 我看到第 35 行和第 56 行的错误。问题是：
-  - 第 35 行：new Uint8Array(sharedBuffer, offset, size) - Uint8Array
-  可以有任意偏移量
-  - 第 56 行：new Float32Array(sharedBuffer, offset, count) -
-  这个应该由对齐检查处理了
-
-  等等，错误信息说第 35 行和第 56 行有 RangeError。让我仔细看：
-
-  - RangeError: Invalid typed array length: 186561 -
-  这不是对齐问题，是数组长度太大了
-  - 这意味着 size 或 count 参数是错误的
-
-  这说明主线程和 Worker 之间的偏移量/大小数据不同步。问题可能是因为
-  sharedMemoryPool.buffer 在传输后，主线程的 usedBytes 计数器和 Worker 不一致。
-
-  实际上，真正的问题是：共享内存池的 usedBytes 在不断增长，但没有重置。每次 AO
-  请求都会分配新的内存，导致偏移量越来越大，最终超出缓冲区范围。
-
-  让我检查何时重置共享内存池：
-
-  Searched for 1 pattern (ctrl+o to expand)
-
-⏺ SharedMemoryPool
-  没有被重置。但更重要的是，我们需要一个更健壮的解决方案。当前的问题是所有 AO
-  请求都在累积分配内存，最终导致缓冲区溢出或偏移量错误。
-
-  让我简化解决方案：不使用共享内存池的累加分配模式，而是在每次 AO 
-  请求时使用固定的内存区域。
-
-  但更直接的修复是：确保所有 TypedArray 创建都能处理共享内存。让我更新 AOWorker
-  来更稳健地处理：

-  如果还有问题，我们需要考虑 SharedArrayBuffer 改造的根本性问题：
-  1. 共享内存池没有重置机制，导致内存耗尽
-  2. 多个并发的 AO 请求会互相干扰
-
-  一个更彻底的解决方案是：每次 AO 请求使用独立的共享内存区域，或者在 Chunk
-  合并完成后重置内存池。

-⏺ 问题清楚了！resultBufferOffset 不是 4 的倍数（如 2982211 % 4 = 3），说明

-
-⏺ 找到 bug 了！padding 被加到 byteSize 上，但 usedBytes
-  增加后，下一次分配的起始位置仍然可能不是 4 的倍数。

-⏺ 偏移量已超过 137MB，超出 128MB 缓冲区。根本问题：
-  1. SharedArrayBuffer 无法真正扩展 - 扩展时创建新缓冲区，但 Worker 仍持有旧引用
-  2. 内存释放只是标记，没有真正回收空间 - usedBytes 只增不减
-
-  最直接解决方案：回退到传统 postMessage 模式，SharedArrayBuffer
-  改造需要更复杂的重构。
-
-  Read 1 file (ctrl+o to expand)
-
-⏺ SharedArrayBuffer 扩展后 Worker 的引用不会自动更新。需要实现循环缓冲区模式 -
-  每次 AO 请求后重置。

Subject: [PATCH 17/66] perf(world): dedup concurrent region loads and add
 background prefetch

- Add _regionLoadPromises Map in WorldRuntime to prevent N concurrent
  IndexedDB reads for the same region during chunk streaming
- Refactor ensureChunkData to reuse ensureRegion, eliminating duplicated
  cache-miss logic
- Add prefetchRegions() to warm up adjacent regions ahead of player movement
- Add 500ms prefetch timer in World (runtime-streaming phase only) with
  dispose cleanup

+# 缓存击穿修复 + Region 预取设计文档
+
+## 背景
+
+当前 `gen-big-map-first` 分支已实现 region 级预生成 + IndexedDB 权威存储架构。运行时 chunk 加载通过 `WorldRuntime.ensureChunkData` 从 `RegionCache` / IndexedDB 纯装载。代码审查发现两个影响运行时加载性能的问题。
+
+## 问题 1：缓存击穿（并发 IndexedDB 读取）
+
+### 现象
+
+`World.update` 同步创建渲染距离内所有 Chunk（最多 7x7 = 49 个），每个 Chunk 调用 `_requestRuntimeChunkRecord`，进而调用 `WorldRuntime.ensureChunkData`。由于：
+
+1. `_requestRuntimeChunkRecord` 不 `await` `ensureChunkData`
+2. `ensureChunkData` 内没有 in-flight Promise 去重
+3. `RegionCache` 只有 LRU 缓存，没有"加载中"状态
+
+导致同一 region 内的多个 chunk 会在同一帧内并发穿透到 IndexedDB，发起多次 `getRegionRecord` 请求读取同一个 region。
+
+### 方案：WorldRuntime 内引入 `_regionLoadPromises` Map
+
+**改动范围**：仅 `src/world/WorldRuntime.js`
+
+**具体设计**：
+
+1. `WorldRuntime` 构造函数新增 `this._regionLoadPromises = new Map()`
+2. 重构 `ensureRegion` 方法：
+   - 先检查 `RegionCache`
+   - 再检查 `_regionLoadPromises`，命中则返回共享 Promise
+   - 否则发起 `getRegionRecord`，将 Promise 存入 Map
+   - 无论成功/失败，完成后从 Map 移除
+3. `ensureChunkData` 改为调用 `ensureRegion`，不再直接访问 `WorldStore`
+
+**关键代码逻辑**：
+
+```javascript
+async ensureRegion(rx, rz) {
+  const regionKey = this._regionKey(rx, rz);
+
+  // 1. 缓存命中
+  const cached = this._regionCache.get(regionKey);
+  if (cached) return cached;
+
+  // 2. 已有正在进行的请求，共享 Promise
+  const existing = this._regionLoadPromises.get(regionKey);
+  if (existing) return existing;
+
+  // 3. 发起新请求
+  const promise = this._worldStore.getRegionRecord(rx, rz)
+    .then(record => {
+      if (record) this._regionCache.set(regionKey, record);
+      this._regionLoadPromises.delete(regionKey);
+      return record;
+    })
+    .catch(err => {
+      this._regionLoadPromises.delete(regionKey);
+      throw err;
+    });
+
+  this._regionLoadPromises.set(regionKey, promise);
+  return promise;
+}
+```
+
+**错误处理**：
+- 请求失败时清理 Map 条目，避免死锁
+- 不自动重试，由下次 chunk 加载触发自然重试
+- 保持现有错误日志
+
+---
+
+## 问题 2：Region 预取
+
+### 现象
+
+当前 chunk 加载完全被动——只有 chunk 进入渲染距离时才触发 `ensureChunkData`。首次进入新 region 时必有 1 次 IndexedDB 读取延迟。
+
+### 方案：定时器驱动 + 预取预算
+
+**改动范围**：`src/world/WorldRuntime.js` + `src/world/World.js`
+
+**具体设计**：
+
+1. `WorldRuntime` 新增 `prefetchRegions(playerCx, playerCz, maxPrefetches = 1)` 方法：
+   - 计算玩家当前 region 坐标
+   - 遍历相邻 4 个 region（上/下/左/右）
+   - 跳过已在 `RegionCache` 或 `_regionLoadPromises` 中的 region
+   - 对未缓存的 region 调用 `ensureRegion` 预热（不 await，不阻塞）
+   - 每轮最多预取 `maxPrefetches` 个（默认 1）
+
+2. `World` 新增预取定时器：
+   - 在 `constructor` 中启动 `setInterval(() => this._runPrefetch(), 500)`
+   - `_runPrefetch` 仅在 `bootstrapState.phase === 'runtime-streaming'` 时执行
+   - 计算玩家当前 chunk 坐标，调用 `worldRuntime.prefetchRegions`
+   - `World.dispose` 中清理定时器（如存在）
+
+**预取参数**：
+- 频率：500ms
+- 范围：相邻 4 个 region（上/下/左/右）
+- 每轮预算：1 个 region
+
+**对 FPS 的影响**：
+- 不占用渲染帧预算（定时器独立于 `requestAnimationFrame`）
+- 每轮最多 1 个异步 IndexedDB 请求，开销极小
+- 预取是"尽力而为"（best-effort），失败不报错
+
+---
+
+## 测试计划
+
+1. **缓存击穿测试**：
+   - 模拟同一 region 内 25 个 chunk 同时调用 `ensureChunkData`
+   - 验证 IndexedDB `getRegionRecord` 只被调用 1 次
+   - 验证所有 chunk 都正确拿到数据
+
+2. **预取测试**：
+   - 玩家移动到新 region 边界前，验证相邻 region 已被预热到 `RegionCache`
+   - 验证 bootstrapping 阶段不触发预取
+   - 验证定时器在 World 卸载时被清理
+
+3. **回归测试**：
+   - `npm run lint`
+   - 浏览器内跑图测试，观察 L 键 / N 键性能日志

+# 缓存击穿修复 + Region 预取 Implementation Plan
+
+> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
+
+**Goal:** 修复 `WorldRuntime.ensureChunkData` 的并发缓存击穿问题，并添加定时器驱动的 Region 预取机制。
+
+**Architecture:** 在 `WorldRuntime` 中引入 `_regionLoadPromises` Map 实现 in-flight 请求去重；在 `World` 中启动 500ms 定时器调用 `WorldRuntime.prefetchRegions` 预热相邻 region。
+
+**Tech Stack:** 纯 ES Modules，无 bundler，浏览器内测试。
+
+---
+
+### Task 1: 重构 `WorldRuntime.ensureRegion` 添加 in-flight Promise 去重
+
+**Files:**
+- Modify: `src/world/WorldRuntime.js:25-35`（构造函数）
+- Modify: `src/world/WorldRuntime.js:72-107`（`ensureChunkData`）
+- Modify: `src/world/WorldRuntime.js:280-290`（`ensureRegion`）
+
+**Step 1: 在构造函数中初始化 `_regionLoadPromises`**
+
+在 `src/world/WorldRuntime.js` 的 `constructor` 中，在 `this._regionSizeInChunks = REGION_SIZE_IN_CHUNKS;` 之后添加：
+
+```javascript
+this._regionLoadPromises = new Map(); // regionKey -> Promise
+```
+
+**Step 2: 重构 `ensureRegion` 添加去重逻辑**
+
+将 `ensureRegion` 方法替换为：
+
+```javascript
+async ensureRegion(rx, rz) {
+  const regionKey = this._regionKey(rx, rz);
+
+  // 1. 缓存命中
+  let region = this._regionCache.get(regionKey);
+  if (region) return region;
+
+  // 2. 检查是否已有正在进行的请求
+  const existingPromise = this._regionLoadPromises.get(regionKey);
+  if (existingPromise) return existingPromise;
+
+  // 3. 发起新请求
+  const loadPromise = this._worldStore.getRegionRecord(rx, rz)
+    .then((record) => {
+      if (record) {
+        this._regionCache.set(regionKey, record);
+      }
+      this._regionLoadPromises.delete(regionKey);
+      return record;
+    })
+    .catch((err) => {
+      this._regionLoadPromises.delete(regionKey);
+      throw err;
+    });
+
+  this._regionLoadPromises.set(regionKey, loadPromise);
+  return loadPromise;
+}
+```
+
+**Step 3: 简化 `ensureChunkData` 为调用 `ensureRegion`**
+
+将 `ensureChunkData` 替换为：
+
+```javascript
+async ensureChunkData(cx, cz) {
+  const { rx, rz } = this._chunkToRegion(cx, cz);
+  const region = await this.ensureRegion(rx, rz);
+
+  if (!region || !region.chunks) {
+    return { status: 'missing-region' };
+  }
+  const chunkKey = this._chunkKey(cx, cz);
+  const chunkData = region.chunks[chunkKey];
+  if (!chunkData) {
+    return { status: 'missing-chunk' };
+  }
+
+  return {
+    status: 'ready',
+    chunkRecord: {
+      cx,
+      cz,
+      blockData: chunkData.blockData || {},
+      staticEntities: chunkData.staticEntities || [],
+      runtimeSeedData: chunkData.runtimeSeedData || {}
+    }
+  };
+}
+```
+
+**Step 4: 运行 lint**
+
+```bash
+npm run lint
+```
+
+Expected: 0 errors, 0 new warnings.
+
+**Step 5: Commit**
+
+```bash
+git add src/world/WorldRuntime.js
+git commit -m "fix(world-runtime): add in-flight promise dedup for region loading
+
+- Introduce _regionLoadPromises Map to share concurrent getRegionRecord calls
+- Refactor ensureChunkData to reuse ensureRegion
+- Prevents N concurrent IndexedDB reads for the same region"
+```
+
+---
+
+### Task 2: 在 `WorldRuntime` 中添加 `prefetchRegions` 方法
+
+**Files:**
+- Modify: `src/world/WorldRuntime.js`
+
+**Step 1: 添加 `prefetchRegions` 方法**
+
+在 `WorldRuntime` 类中 `getStats()` 方法之前添加：
+
+```javascript
+/**
+ * 预取玩家周围的 region（尽力而为，不阻塞）

+git commit -m "feat(world-runtime): add prefetchRegions for background region warmup
+
+- Prefetch up to 4 adjacent regions (N/S/E/W)
+- Budget-controlled: max 1 region per call by default
+- Skips already-cached or in-flight regions"
+```
+
+---
+
+### Task 3: 在 `World` 中添加预取定时器
+
+**Files:**
+- Modify: `src/world/World.js:76-178`（constructor）
+- Modify: `src/world/World.js:738-893`（update 方法附近）
+
+**Step 1: 在 constructor 中启动预取定时器**
+
+在 `src/world/World.js` 的 `constructor` 末尾（`this.worldGenerationService.setWorld(this);` 之后）添加：
+
+```javascript
+// --- Region 预取定时器 ---
+this._prefetchIntervalMs = 500;
+this._prefetchTimer = globalThis.setInterval(() => {
+  this._runPrefetch();
+}, this._prefetchIntervalMs);
+```
+
+**Step 2: 添加 `_runPrefetch` 方法**
+
+在 `World` 类中 `isGameplayReady()` 方法之后添加：
+
+```javascript
+_runPrefetch() {
+  if (this.bootstrapState.phase !== 'runtime-streaming') return;
+  if (!this.worldRuntime) return;
+
+  const playerCx = Math.floor(this._lastPlayerPos.x / CHUNK_SIZE);
+  const playerCz = Math.floor(this._lastPlayerPos.z / CHUNK_SIZE);
+  this.worldRuntime.prefetchRegions(playerCx, playerCz, 1);
+}
+```
+
+**Step 3: 添加定时器清理**
+
+在 `src/world/World.js` 中找到或确认有 dispose/cleanup 逻辑。如果没有专门的 dispose 方法，在 constructor 附近添加一个 `dispose` 方法：
+
+```javascript
+dispose() {
+  if (this._prefetchTimer) {
+    globalThis.clearInterval(this._prefetchTimer);
+    this._prefetchTimer = null;
+  }
+  // 其他清理逻辑...
+}
+```
+
+如果 `World` 类已有 `dispose` 方法，只需在其中添加定时器清理。
+
+**Step 4: 运行 lint**
+
+```bash
+npm run lint
+```
+
+Expected: 0 errors, 0 new warnings.
+
+**Step 5: Commit**
+
+```bash
+git add src/world/World.js
+git commit -m "feat(world): add background region prefetch timer
+
+- 500ms interval, only active during runtime-streaming phase
+- Calls worldRuntime.prefetchRegions to warm up adjacent regions
+- Clean up timer on dispose"
+```
+
+---
+
+### Task 4: 运行完整 lint 和回归验证
+
+**Step 1: 运行 lint**
+
+```bash
+npm run lint
+```
+
+Expected: 0 errors, 0 new warnings.（允许历史遗留的 50 个警告）
+
+**Step 2: 启动开发服务器并浏览器内测试**
+
+```bash
+npm run start
+```
+
+打开浏览器访问 `http://localhost:8080`
+
+验证项：
+- [ ] 游戏正常启动，预生成完成后进入主世界
+- [ ] 按 L 键查看 chunk perf 日志，`load-from-record` 时间稳定
+- [ ] 按 N 键查看 streaming perf 日志，跑图时无明显卡顿峰值
+- [ ] 跨越 region 边界时，chunk 加载延迟无明显增加
+
+**Step 3: Commit（如需）**
+
+如果测试中发现并修复了问题，单独提交。
+

+
+## 风险与回退
+
+| 风险 | 缓解措施 |
+|------|---------|
+| `_regionLoadPromises` 在异常路径下未清理 | `.catch` 中已添加 `delete`，且 Promise 链总会 settle |
+| 预取定时器泄漏 | `dispose` 方法中已添加 `clearInterval` |
+| 预取增加 IndexedDB 压力 | 每轮最多 1 个 region，频率 500ms，影响极小 |
+| `ensureChunkData` 调用 `ensureRegion` 引入循环依赖 | 无循环，`ensureChunkData` 调用 `ensureRegion`，`ensureRegion` 不调用 `ensureChunkData` |

Subject: [PATCH 18/66] perf(chunk): add lightSourceCoords derived index for
 fast light source iteration

Replace full blockData scan in _registerLightSources/_unregisterLightSources
with a dedicated Set index that tracks light-emitting block coordinates.

The index is maintained synchronously across all blockData write paths:
- _injectBlockData (bulk load / record restore)
- _updateBlockState (single block mutation)
- removeBlocksBatch (batch deletion)
- acceptScatteredBlocks / appendScatteredBlocks (worker result / overflow)

This eliminates iterating 3000-4000 blockData entries per chunk during
finalizeNonDeferredPhase, reducing light registration from ~8-15ms to <1ms.

Subject: [PATCH 19/66] fix(chunk): populate pendingRuntimeEntities to restore
 runtime entities on chunk load

pendingRuntimeEntities was initialized as null and never assigned a non-null
value, making the entity restore logic in finalizeNonDeferredPhase dead code.
This caused zombie nests, turrets, and minecarts to be lost when chunks were
loaded at runtime (player exploring new areas).

Fixes both loading paths:
- loadFromRecord: now merges persistence cache entities and calls
  finalizeNonDeferredPhase to trigger restore.
- assembleEntityPhase: now includes minecarts in the entity merge and
  populates pendingRuntimeEntities from the merged snapshot.

+# Runtime Entities Persistence Design
+
+**日期**: 2026-04-28
+**状态**: 待实现
+**范围**: turret、minecart、zombieNest 三类交互实体的 WorldStore 持久化
+
+## 背景
+
+当前项目中 turret、minecart、zombieNest 三类交互实体的持久化走的是旧的 `persistenceService.cache` 路径。在 WorldStore（RegionRecord）架构引入后，这些实体的数据没有正确写入新的权威数据源，导致 chunk 销毁/重新加载时实体可能丢失。
+
+## 目标
+
+将三类交互实体的持久化迁移到 WorldStore 的 `RegionRecord.runtimeEntities` 字段，确保：
+1. 实体创建/销毁时正确写入 IndexedDB
+2. Chunk 加载时从 WorldStore 读取并恢复实体实例
+3. 只持久化基础属性（位置+朝向），不保存运行时计数或速度
+
+## 数据格式
+
+### RegionRecord 结构
+
+```
+RegionRecord
+└── chunks
+    └── "cx,cz"
+        ├── blockData: { ... }
+        ├── staticEntities: [ ... ]          // 静态模型（树、建筑等）
+        ├── runtimeEntities: {               // 运行时交互实体（新增）
+        │     turrets: [
+        │       { position: { x, y, z }, rotation: number }
+        │     ],
+        │     minecarts: [
+        │       { position: { x, y, z }, direction: number }
+        │     ],
+        │     zombieNests: [
+        │       { position: { x, y, z }, criticalBlock: { x, y, z, type } }
+        │     ]
+        │   }
+        └── runtimeSeedData: { ... }
+```
+
+### 各实体字段说明
+
+| 实体类型 | 字段 | 说明 |
+|---------|------|------|
+| turret | `position` | 方块坐标（取整） |
+| | `rotation` | 炮塔当前旋转角度（弧度） |
+| minecart | `position` | 矿车当前位置 |
+| | `direction` | 矿车朝向方向 |
+| zombieNest | `position` | 巢穴位置 |
+| | `criticalBlock` | 关键方块位置和类型 |
+
+## 架构设计
+
+### 写入路径
+
+```
+实体创建/销毁
+    ↓
+Manager.saveXxxToSnapshot() / removeXxxFromSnapshot()
+    ↓
+worldStore.putChunkRecord(cx, cz, chunkRecord)
+    ↓
+PersistenceWorker: 读 RegionRecord → 修改 chunk → 写回 RegionRecord
+```
+
+- 各 Manager 的写入方法改为调用 `worldStore.putChunkRecord()` 替代 `persistenceService.saveChunkData()`
+- `putChunkRecord` 是异步操作，不阻塞主线程
+
+### 读取路径
+
+```
+Chunk 加载
+    ↓
+Chunk._createFromWorldStore()
+    ↓
+读取 chunkRecord.runtimeEntities → pendingRuntimeEntities
+    ↓
+finalizeNonDeferredPhase()
+    ↓
+各 Manager.restoreXxxForChunk() 重建实体实例
+```
+
+- 现有 `finalizeNonDeferredPhase()` 中已有从 `pendingRuntimeEntities` 恢复的逻辑
+- 只需要确保 `_createFromWorldStore()` 正确填充该字段
+- 移除对旧 `persistenceService.cache` 的 fallback 读取
+
+## 边界情况处理
+
+1. **矿车跨 chunk 移动**：从旧 chunk 移除 + 添加到新 chunk，两个 `putChunkRecord` 不原子。下次加载时按位置键去重。
+2. **数据格式版本**：预留 `runtimeEntities.version` 字段，未来扩展时使用。
+3. **RegionRecord 不存在**：写入前检查 region 是否存在，不存在则跳过并 warn。
+
+## 改动文件清单
+
+| 文件 | 改动内容 |
+|------|---------|
+| `src/world/WorldStore.js` | `getChunkRecord`/`putChunkRecord` 支持 `runtimeEntities` 字段 |
+| `src/world/Chunk.js` | `_createFromWorldStore()` 读取 `runtimeEntities`，移除旧 cache fallback |
+| `src/actors/turret/TurretManager.js` | 写入路径改为 worldStore |
+| `src/actors/minecart/MinecartManager.js` | 写入路径改为 worldStore |
+| `src/actors/zombie-nest/ZombieNestManager.js` | 写入路径改为 worldStore |
+
+## 后续工作（不在本次范围）
+
+- chest（宝箱）和 lightSource（光源）的持久化
+- 实体运行时状态的完整持久化（速度、刷怪计数等）

+# Runtime Entities Persistence Implementation Plan
+
+> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
+
+**Goal:** Migrate turret, minecart, and zombie nest persistence from the old `persistenceService.cache` to WorldStore `RegionRecord.runtimeEntities`, ensuring entities survive chunk unload/reload cycles.
+
+**Architecture:** Add a `runtimeEntities` field to `RegionRecord.chunks[cx,cz]`. Entity managers write via `worldStore.putChunkRecord()`. Chunk reads via `getChunkRecord()` → `pendingRuntimeEntities` → `finalizeNonDeferredPhase()` restores instances.
+
+**Tech Stack:** JavaScript (ES Modules), IndexedDB via PersistenceWorker, WorldStore/RegionRecord architecture
+
+---
+
+### Task 1: WorldStore — 在 getChunkRecord/putChunkRecord 中支持 runtimeEntities
+
+**Files:**
+- Modify: `src/world/WorldStore.js:124-165`
+- Test: 浏览器中验证
+
+**Step 1: 修改 getChunkRecord 返回值**
+
+在 `src/world/WorldStore.js` 的 `getChunkRecord` 方法（约第124行）中，返回对象增加 `runtimeEntities` 字段：
+
+```javascript
+// 当前返回：
+return {
+  cx,
+  cz,
+  blockData: chunkData.blockData || {},
+  staticEntities: chunkData.staticEntities || [],
+  runtimeSeedData: chunkData.runtimeSeedData || {}
+};
+
+// 修改为：
+return {
+  cx,
+  cz,
+  blockData: chunkData.blockData || {},
+  staticEntities: chunkData.staticEntities || [],
+  runtimeEntities: chunkData.runtimeEntities || null,
+  runtimeSeedData: chunkData.runtimeSeedData || {}
+};
+```
+
+同样修改 `getChunkRecordsInRegion` 方法（约第147行）中对应的返回对象，也增加 `runtimeEntities` 字段。
+
+**Step 2: 修改 putChunkRecord 接受 runtimeEntities**
+
+`putChunkRecord` 方法（约第178行）直接接收 `chunkRecord` 对象并写入 `region.chunks[key] = chunkRecord`。由于是全对象覆盖写入，只要调用方传入 `runtimeEntities` 字段，自动就会被保存。**无需修改代码**，只需要在文档中确认该字段会被透传。
+
+**Step 3: 确认无需改动**
+
+- `saveRegionRecord` 和 `saveRegionRecordsBatch` 是直接序列化整个 region 对象，`runtimeEntities` 自动包含
+- PersistenceWorker 的 `saveRegionRecord` handler 也是直接 `store.put({ regionKey, data: record })`，自动序列化所有字段
+
+**Step 4: Commit**
+
+```bash
+git add src/world/WorldStore.js
+git commit -m "feat(worldstore): add runtimeEntities field to getChunkRecord projection"
+```
+
+---
+
+### Task 2: Chunk — 从 worldStore 读取 runtimeEntities 替代旧 cache 路径
+
+**Files:**
+- Modify: `src/world/Chunk.js:282-346` (loadFromRecord 方法)
+
+**Step 1: 修改 loadFromRecord 中的 runtimeEntities 读取逻辑**
+
+在 `src/world/Chunk.js` 的 `loadFromRecord` 方法中（约第315-336行），将旧 cache 路径替换为从 `chunkRecord.runtimeEntities` 读取：
+
+```javascript
+// 当前代码（第315-336行）：
+// 从持久化缓存中恢复运行时实体数据（炮塔、矿车、丧尸巢穴）
+const persistence = getPersistenceService();
+const chunkKey = `${this.cx},${this.cz}`;
+const existingData = persistence?.cache?.get?.(chunkKey);
+if (existingData?.entities) {
+  this.pendingSnapshot.entities = {
+    ...this.pendingSnapshot.entities,
+    ...existingData.entities
+  };
+  const entities = this.pendingSnapshot.entities;
+  if (
+    (Array.isArray(entities.zombieNests) && entities.zombieNests.length > 0) ||
+    (Array.isArray(entities.turrets) && entities.turrets.length > 0) ||
+    (Array.isArray(entities.minecarts) && entities.minecarts.length > 0)
+  ) {
+    this.pendingRuntimeEntities = {
+      zombieNests: entities.zombieNests || [],
+      turrets: entities.turrets || [],
+      minecarts: entities.minecarts || []
+    };
+  }
+}
+
+// 替换为：
+// 从 WorldStore runtimeEntities 恢复运行时实体数据
+const runtimeEntities = chunkRecord.runtimeEntities;
+if (runtimeEntities && typeof runtimeEntities === 'object') {
+  const zombieNests = Array.isArray(runtimeEntities.zombieNests) ? runtimeEntities.zombieNests : [];
+  const turrets = Array.isArray(runtimeEntities.turrets) ? runtimeEntities.turrets : [];
+  const minecarts = Array.isArray(runtimeEntities.minecarts) ? runtimeEntities.minecarts : [];
+  if (zombieNests.length > 0 || turrets.length > 0 || minecarts.length > 0) {
+    this.pendingRuntimeEntities = { zombieNests, turrets, minecarts };
+  }
+}
+```
+
+**Step 2: Commit**
+
+```bash
+git add src/world/Chunk.js
+git commit -m "feat(chunk): read runtimeEntities from worldStore instead of old persistence cache"
+```
+
+---
+
+### Task 3: TurretManager — 写入路径迁移到 WorldStore
+
+**Files:**
+- Modify: `src/actors/turret/TurretManager.js:80-157` (ensureChunkSnapshot, saveTurretToSnapshot, removeTurretFromSnapshot)
+- Test: 浏览器中放置/销毁炮塔，刷新页面验证炮塔保留
+
+**Step 1: 添加 worldStore 注入**
+
+在 TurretManager 的 `getPersistenceService` 方法之后添加 `getWorldStore` 方法：
+
+```javascript
+/**
+ * 获取 worldStore（优先测试注入）
+ * @returns {object|null}
+ */
+getWorldStore() {
+  return globalThis._worldStore || this.world?.worldStore || null;
+}
+```
+
+**Step 2: 替换 saveTurretToSnapshot**
+
+替换现有 `saveTurretToSnapshot` 方法（约第119-135行）：
+
+```javascript
+/**
+ * 将炮塔写入 WorldStore
+ * @param {Turret} turret
+ * @returns {void}
+ */
+async saveTurretToSnapshot(turret) {
+  const worldStore = this.getWorldStore();
+  if (!worldStore) return;
+  const entry = this.toTurretSnapshot(turret);
+  if (!entry) return;
+
+  const cx = Math.floor(entry.position.x / PERSISTENCE_CONFIG.CHUNK_SIZE);
+  const cz = Math.floor(entry.position.z / PERSISTENCE_CONFIG.CHUNK_SIZE);
+
+  // 读取当前 chunkRecord（包含已有的 runtimeEntities）
+  const chunkRecord = await worldStore.getChunkRecord(cx, cz);
+  if (!chunkRecord) return;
+
+  // 初始化 runtimeEntities
+  if (!chunkRecord.runtimeEntities) chunkRecord.runtimeEntities = {};
+  if (!Array.isArray(chunkRecord.runtimeEntities.turrets)) {
+    chunkRecord.runtimeEntities.turrets = [];
+  }
+
+  // 更新或添加
+  const posKey = this.getPositionKey(entry.position);
+  const list = chunkRecord.runtimeEntities.turrets;
+  const idx = list.findIndex(item => this.getPositionKey(item.position) === posKey);
+  if (idx >= 0) list[idx] = entry;
+  else list.push(entry);
+
+  // 写回
+  await worldStore.putChunkRecord(cx, cz, chunkRecord);
+}
+```
+
+**Step 3: 替换 removeTurretFromSnapshot**
+
+替换现有 `removeTurretFromSnapshot` 方法（约第142-157行）：
+
+```javascript
+/**
+ * 从 WorldStore 中移除炮塔
+ * @param {Turret} turret
+ * @returns {void}
+ */
+async removeTurretFromSnapshot(turret) {
+  const worldStore = this.getWorldStore();
+  if (!worldStore) return;
+  const entry = this.toTurretSnapshot(turret);
+  if (!entry) return;
+
+  const cx = Math.floor(entry.position.x / PERSISTENCE_CONFIG.CHUNK_SIZE);
+  const cz = Math.floor(entry.position.z / PERSISTENCE_CONFIG.CHUNK_SIZE);
+
+  const chunkRecord = await worldStore.getChunkRecord(cx, cz);
+  if (!chunkRecord?.runtimeEntities?.turrets) return;
+
+  const posKey = this.getPositionKey(entry.position);
+  chunkRecord.runtimeEntities.turrets = chunkRecord.runtimeEntities.turrets.filter(
+    item => this.getPositionKey(item.position) !== posKey
+  );
+
+  await worldStore.putChunkRecord(cx, cz, chunkRecord);
+}
+```
+
+**Step 4: 移除 ensureChunkSnapshot 和旧的 cache 相关方法**
+
+删除 `ensureChunkSnapshot` 方法（约第84-98行），不再需要。保留 `getPersistenceService` 方法（可能其他地方还有引用）。
+
+**Step 5: 更新 createTurret 中的 persist 调用**
+
+`createTurret` 方法（约第208行）中 `this.saveTurretToSnapshot(turret)` 现在是 async 方法，但不需要 await（fire-and-forget 异步写入）：
+
+```javascript
+// 保持不变，因为 saveTurretToSnapshot 内部已经是异步的
+// 不需要添加 await，避免阻塞主线程
+if (shouldPersist) {
+  this.saveTurretToSnapshot(turret);
+}
+```
+
+**Step 6: Run lint**
+
+```bash
+npm run lint
+```
+
+**Step 7: Commit**
+
+```bash
+git add src/actors/turret/TurretManager.js
+git commit -m "feat(turret): migrate persistence to WorldStore runtimeEntities"
+```
+
+---
+
+### Task 4: MinecartManager — 写入路径迁移到 WorldStore
+
+**Files:**
+- Modify: `src/actors/minecart/MinecartManager.js:286-350` (ensureChunkSnapshot, saveMinecartToSnapshot, removeMinecartFromSnapshot)
+- Test: 浏览器中放置/拾取矿车，刷新页面验证矿车保留
+
+**Step 1: 添加 worldStore 注入**
+
+在 MinecartManager 的 `getPersistenceService` 方法之后添加：
+
+```javascript
+/**
+ * 获取 worldStore（优先测试注入）
+ * @returns {object|null}
+ */
+getWorldStore() {
+  return globalThis._worldStore || this.world?.worldStore || null;
+}
+```
+
+**Step 2: 替换 saveMinecartToSnapshot**
+
+替换现有方法（约第306-326行）：
+
+```javascript
+/**
+ * 将矿车写入 WorldStore
+ * @param {Minecart} minecart
+ */
+async saveMinecartToSnapshot(minecart) {
+  const worldStore = this.getWorldStore();
+  if (!worldStore) return;
+
+  const entry = minecart.toJSON();
+  const chunkKey = this.getChunkKeyByPosition(entry);

+  if (!Array.isArray(chunkRecord.runtimeEntities.minecarts)) {
+    chunkRecord.runtimeEntities.minecarts = [];
+  }
+
+  const list = chunkRecord.runtimeEntities.minecarts;
+  const posKey = this.getPositionKey(entry);
+  const idx = list.findIndex(item => this.getPositionKey(item) === posKey);
+  if (idx >= 0) list[idx] = entry;
+  else list.push(entry);
+
+  await worldStore.putChunkRecord(cx, cz, chunkRecord);
+}
+```
+
+**Step 3: 替换 removeMinecartFromSnapshot**
+
+替换现有方法（约第332-350行）：
+
+```javascript
+/**
+ * 从 WorldStore 中移除矿车
+ * @param {Minecart} minecart
+ */
+async removeMinecartFromSnapshot(minecart) {
+  const worldStore = this.getWorldStore();
+  if (!worldStore) return;
+
+  const entry = minecart.toJSON();
+  const chunkKey = this.getChunkKeyByPosition(entry);
+  const [cx, cz] = chunkKey.split(',').map(Number);
+
+  const chunkRecord = await worldStore.getChunkRecord(cx, cz);
+  if (!chunkRecord?.runtimeEntities?.minecarts) return;
+
+  const posKey = this.getPositionKey(entry);
+  chunkRecord.runtimeEntities.minecarts = chunkRecord.runtimeEntities.minecarts.filter(
+    item => this.getPositionKey(item) !== posKey
+  );
+
+  await worldStore.putChunkRecord(cx, cz, chunkRecord);
+}
+```
+
+**Step 4: 删除 ensureChunkSnapshot 方法**
+
+删除 `ensureChunkSnapshot` 方法（约第286-300行）。
+
+**Step 5: Run lint**
+
+```bash
+npm run lint

 # Runtime Entities Persistence Design
 
-**日期**: 2026-04-28
-**状态**: 待实现
-**范围**: turret、minecart、zombieNest 三类交互实体的 WorldStore 持久化
+**日期**: 2026-04-28  
+**状态**: 修订版  
+**范围**: `turret`、`minecart`、`zombieNest` 在 `worldStore / IndexedDB` 权威存储机制下的持久化、恢复、卸载与渲染协同
 
-## 背景
+## 1. 这次失败暴露出的根因
 
-当前项目中 turret、minecart、zombieNest 三类交互实体的持久化走的是旧的 `persistenceService.cache` 路径。在 WorldStore（RegionRecord）架构引入后，这些实体的数据没有正确写入新的权威数据源，导致 chunk 销毁/重新加载时实体可能丢失。
+上一次方案失败，不是因为少改了几行，而是因为设计抽象层级错了。它把三类“特殊实体”都当成了同一种 `runtimeEntities` 数据迁移问题，但真实代码里三者的渲染形态、与 `blockData` 的关系、卸载语义、恢复入口都不同。
 
-## 目标
+失败点主要有四类：
 
-将三类交互实体的持久化迁移到 WorldStore 的 `RegionRecord.runtimeEntities` 字段，确保：
-1. 实体创建/销毁时正确写入 IndexedDB
-2. Chunk 加载时从 WorldStore 读取并恢复实体实例
-3. 只持久化基础属性（位置+朝向），不保存运行时计数或速度
+1. **把特殊实体错误地视为纯元数据对象**
+   - `zombieNest` 没有独立视觉模型，视觉主体是结构方块，实体实例只负责刷怪与完整性检查。
+   - `minecart` 没有落地到 `blockData`，完全是运行时对象，由独立 Instanced Renderer 渲染。
+   - `turret` 是混合体：底座/柱子是方块，炮塔头部是独立 Three.js 对象。
 
-## 数据格式
+2. **只考虑了 `Chunk.loadFromRecord()`，没考虑另一条真实装载链路**
+   - 当前项目至少有两条恢复路径：
+     - `WorldRuntime.ensureChunkData()` -> `Chunk.loadFromRecord()`
+     - `Chunk.gen()` / `assembleEntityPhase()` 通过 `persistenceService.cache` 合并快照
+   - 只改第一条路径，第二条路径仍然读旧数据，会导致行为不一致。
 
-### RegionRecord 结构
+3. **直接让各 Manager 自己 `getChunkRecord -> 改对象 -> putChunkRecord`，没有解决并发覆盖**
+   - `WorldRuntime.flushChunk()`、`flushAllDirty()`、Manager 写入、chunk 卸载前写回，都会碰同一个 `chunkRecord`。
+   - 没有一个“按 chunk 串行化”的更新接口，读改写天然存在竞态。
 
-```
-RegionRecord
-└── chunks
-    └── "cx,cz"
-        ├── blockData: { ... }
-        ├── staticEntities: [ ... ]          // 静态模型（树、建筑等）
-        ├── runtimeEntities: {               // 运行时交互实体（新增）
-        │     turrets: [
-        │       { position: { x, y, z }, rotation: number }
-        │     ],
-        │     minecarts: [
-        │       { position: { x, y, z }, direction: number }
-        │     ],
-        │     zombieNests: [
-        │       { position: { x, y, z }, criticalBlock: { x, y, z, type } }
-        │     ]
-        │   }
-        └── runtimeSeedData: { ... }
-```
+4. **没有定义实体“激活态”和“持久态”的边界**
+   - 当前代码里，特殊实体大多是全局 manager 持有的活动实例；chunk 卸载并不天然等于实体实例销毁。
+   - 方案没有明确：远离后是“继续活着但不可见”，还是“按 chunk 停用，靠近再恢复”。
 
-### 各实体字段说明
+本次修订要先把这四个问题讲清楚，再谈实现计划。
 
-| 实体类型 | 字段 | 说明 |
-|---------|------|------|
-| turret | `position` | 方块坐标（取整） |
-| | `rotation` | 炮塔当前旋转角度（弧度） |
-| minecart | `id` | 矿车唯一标识符（用于跨 chunk 去重） |
-| | `position` | 矿车当前位置 |
-| | `direction` | 矿车朝向方向 |
-| zombieNest | `position` | 巢穴位置 |
-| | `criticalBlock` | 关键方块位置和类型 |
+---
 
-## 架构设计
+## 2. 现状澄清：三类特殊实体并不等价
 
-### 写入路径
+### 2.1 `turret`
 
-```
-实体创建/销毁
-    ↓
-Manager.saveXxxToSnapshot() / removeXxxFromSnapshot()
-    ↓
-worldStore.putChunkRecord(cx, cz, chunkRecord)
-    ↓
-PersistenceWorker: 读 RegionRecord → 修改 chunk → 写回 RegionRecord
-```
+代码事实：
+- 放置时先往世界写入底座与柱子方块，再创建 `Turret` 实例。见 [TurretPlacementHandler.js](/Users/bachi/jaylli/mc-lite/src/actors/turret/TurretPlacementHandler.js) 。
+- `Turret` 自己再创建炮塔头部、炮管等独立 `Three.js` 对象，直接挂到 `scene`，不属于 chunk mesh。见 [Turret.js](/Users/bachi/jaylli/mc-lite/src/actors/turret/Turret.js) 。
+- 完整性校验依赖世界中的关键方块是否仍存在。
+
+结论：
+- `turret` 不是“只要恢复一条 runtimeEntities 记录就够了”。
+- 它同时依赖两套数据：
+  - `blockData`：底座/柱子，是视觉与物理的一部分
+  - `runtimeEntities`：炮塔头部逻辑、朝向、生命周期
+
+### 2.2 `zombieNest`
+
+代码事实：
+- 放置时先生成并落地方块结构，再创建 `ZombieNest` 实例。见 [ZombieNestPlacementHandler.js](/Users/bachi/jaylli/mc-lite/src/actors/zombie-nest/ZombieNestPlacementHandler.js) 。
+- `ZombieNest` 本身没有独立 mesh；它只是逻辑体，依赖 `criticalBlock` 做完整性校验，并定时刷怪。见 [ZombieNest.js](/Users/bachi/jaylli/mc-lite/src/actors/zombie-nest/ZombieNest.js) 。
+
+结论：
+- `zombieNest` 的“渲染恢复”主要是结构方块通过 chunk 正常加载、consolidation、AO 刷新后重新显示。
+- `runtimeEntities` 里保存的是逻辑实体，而不是视觉主体。
+
+### 2.3 `minecart`
+
+代码事实：
+- 矿车不写结构方块，只依赖轨道方块存在。
+- 渲染完全由 `MinecartInstancedRenderer` 负责；`Minecart` 只是数据对象。见 [Minecart.js](/Users/bachi/jaylli/mc-lite/src/actors/minecart/Minecart.js) 与 [MinecartManager.js](/Users/bachi/jaylli/mc-lite/src/actors/minecart/MinecartManager.js) 。
+- 卸载 chunk 前已有 `stopMinecartsForChunk()` 逻辑，会停止运动并写快照。
+
+结论：
+- `minecart` 是最接近“纯 runtime entity”的对象。
+- 但它又依赖轨道方块这一外部支撑条件，不能脱离 `blockData` 单独看。
+
+---
+
+## 3. 修订后的权威模型
+
+### 3.1 三层真相来源
+
+在新的 `worldStore` 机制下，必须严格区分三层：
+
+1. **IndexedDB / RegionRecord**
+   - 唯一权威持久化数据源
+   - 保存 `blockData`、`staticEntities`、`runtimeSeedData`、`runtimeEntities`
+
+2. **Chunk runtime working set**
+   - 当前已加载 chunk 的内存工作集
+   - `blockData Map`、可见面、AO、consolidation 状态属于这一层
+   - 不是权威，只是权威数据的活动投影
+
+3. **Manager active instances**
+   - `turretManager.turrets`
+   - `minecartManager.minecarts`
+   - `zombieNestManager.nests`
+   - 这些实例是“活动态对象”，不是权威数据源
+
+### 3.2 `persistenceService.cache` 的新定位
+
+`persistenceService.cache` 不能再被视为权威来源。
+
+修订后它只能有两个用途：
+
+1. **旧装载路径兼容桥**
+   - 仍在 `Chunk.gen()` / `assembleEntityPhase()` 中存在时，可作为临时桥接层
+
+2. **会话级工作缓存**
+   - 用于旧代码尚未清理前避免大范围重构
+
+必须禁止的事情：
+- 新业务状态继续只写 `cache` 不写 `worldStore`
+- `cache` 覆盖 `worldStore` 权威值
+- 不经统一合并策略直接从多个入口并发写 `cache` 和 `worldStore`
+
+---
+
+## 4. 新的数据模型
 
-- 各 Manager 的写入方法改为调用 `worldStore.putChunkRecord()` 替代 `persistenceService.saveChunkData()`
-- `putChunkRecord` 是异步操作，不阻塞主线程
+### 4.1 `ChunkRecord.runtimeEntities`
 
-### 读取路径
+不再继续沿用“若干松散数组 + Manager 自己拼字段”的做法。修订后统一成带版本号的结构。
 
+```js
+chunkRecord.runtimeEntities = {
+  version: 1,
+  byType: {
+    turrets: [
+      {
+        id: 'turret_xxx',
+        ownerChunk: 'cx,cz',
+        anchor: { x, y, z },
+        renderState: {
+          yaw: number,
+          pitch: number
+        },
+        support: {
+          kind: 'turret_base',
+          criticalBlocks: [
+            { x, y, z, type: 'obsidian' },
+            { x, y, z, type: 'obsidian' }
+          ]
+        }
+      }
+    ],
+    minecarts: [
+      {
+        id: 'minecart_xxx',
+        ownerChunk: 'cx,cz',
+        anchor: { x, y, z },
+        motionState: {
+          orientation: number,
+          movementState: 'IDLE' | 'MOVING_FORWARD' | 'MOVING_BACKWARD',
+          lastTrackPosition: { x, y, z } | null
+        },
+        linkState: {
+          linkedMinecartIds: []
+        },
+        support: {
+          kind: 'track',
+          trackBlock: { x, y, z }
+        }
+      }
+    ],
+    zombieNests: [
+      {
+        id: 'zombie_nest_xxx',
+        ownerChunk: 'cx,cz',
+        anchor: { x, y, z },
+        criticalBlock: { x, y, z, type },
+        spawnState: {
+          lastSpawnAt: number
+        }
+      }
+    ]
+  }
+}
 ```
-Chunk 加载
-    ↓
-Chunk._createFromWorldStore()
-    ↓
-读取 chunkRecord.runtimeEntities → pendingRuntimeEntities
-    ↓
-finalizeNonDeferredPhase()
-    ↓
-各 Manager.restoreXxxForChunk() 重建实体实例
+
+### 4.2 为什么需要 `id`
+
+旧方案里 `turret` / `zombieNest` 用位置去重，`minecart` 才有稳定 `id`。这不够。
+
+必须统一要求三类实体都有稳定 `id`，原因：
+- 支持 chunk 卸载/恢复时识别“同一个实体”
+- 避免位置微调、朝向变化、特殊交互导致误判为新对象
+- 为未来支持跨 chunk 迁移、调试追踪、链路日志打基础
+
+### 4.3 为什么要保存比“位置+朝向”更多的状态
+
+上次设计要求“只保存基础属性（位置+朝向）”，这个结论对当前系统不成立。
+
+至少要保留：
+- `minecart.lastTrackPosition`：否则回弹与停止位置会漂
+- `minecart.linkedMinecartIds`：否则重载后联动车组关系丢失
+- `zombieNest.lastSpawnAt`：否则玩家可以通过卸载/加载重置刷怪节奏
+- `turret.yaw / pitch`：否则恢复时炮塔头部突兀跳回默认朝向
+
+不必保存的状态：
+- `turret` 炮弹对象
+- `zombieNest` 当前已生成的敌人引用
+- `minecart` 临时速度向量（可选，第一期可以不保）
+
+---
+
+## 5. 统一生命周期设计
+
+### 5.1 持久态 vs 激活态
+
+修订后，所有特殊实体都遵循同一个生命周期：
+
+1. **持久态记录存在于 `worldStore`**
+2. **chunk 进入激活范围后，Manager 基于记录创建活动实例**
+3. **chunk 卸载时，活动实例被停用/销毁，但持久态记录保留**
+4. **再次进入范围时，再从持久态记录恢复活动实例**
+
+这意味着：
+- 不能再依赖“实例一直挂在 manager 里，远离也不回收”的隐式行为
+- 必须把“按 chunk 激活/停用”设计成显式 API
+
+### 5.2 放置流程
+
+#### `turret`
+1. 通过 `world.setBlock()` 写入底座与柱子到 `blockData`
+2. 写入或更新 `runtimeEntities.byType.turrets`
+3. 若 owner chunk 当前已激活，则创建 `Turret` 实例并挂 scene
+
+#### `zombieNest`
+1. 通过结构 loader 落地巢穴方块到 `blockData`
+2. 写入 `runtimeEntities.byType.zombieNests`
+3. 若 owner chunk 已激活，则创建 `ZombieNest` 逻辑实例
+
+#### `minecart`
+1. 校验轨道方块存在
+2. 写入 `runtimeEntities.byType.minecarts`
+3. 若 owner chunk 已激活，则创建 `Minecart` 实例并让 instanced renderer 纳入渲染
+
+### 5.3 chunk 卸载流程
+
+这是上次方案完全没定义清楚的部分。
+
+修订后要求：
+
+#### `turret`
+- 卸载 owner chunk 前，销毁炮塔活动实例的独立视觉对象
+- **不得删除 `runtimeEntities` 记录**
+- **不得删除底座/柱子 `blockData`**
+
+#### `zombieNest`
+- 卸载 owner chunk 前，销毁逻辑实例
+- 结构方块会随着 chunk 自身卸载而消失，无需额外清理
+- **不得删除 `runtimeEntities` 记录**
+
+#### `minecart`
+- 先停止运动、落盘最新状态
+- 再销毁活动实例
+- **不得删除 `runtimeEntities` 记录**
+
+### 5.4 chunk 恢复流程
+
+恢复必须放在 chunk 地形/方块准备完成之后，否则完整性检查和依赖方块查询会读到不完整状态。
+
+统一顺序：
+1. `blockData` 注入
+2. 普通方块 mesh / consolidation 基础准备完成
+3. `runtimeEntities` 进入 `pendingRuntimeEntities`
+4. `finalizeNonDeferredPhase()` 或等价阶段调用 manager 的 `restoreForChunk()`
+
+### 5.5 交互删除 / 结构损坏流程
+
+#### `turret`
+- 若关键柱子被破坏，活动实例销毁
+- 同步删除其 `runtimeEntities` 记录
+- 底座/残余方块是否保留，按当前玩法决定；第一期保持现状，只删除逻辑实体记录
+
+#### `zombieNest`
+- 若 `criticalBlock` 被破坏，活动实例销毁
+- 同步删除 `runtimeEntities` 记录
+- 结构残骸是否自动清理，不属于本次持久化改造范围
+
+#### `minecart`
+- 拾取/爆炸/碰撞销毁时，删除 `runtimeEntities` 记录
+- 轨道方块仍由普通 `blockData` 自己管理
+
+---
+
+## 6. 渲染与 consolidation 的正确关系
+
+这是本次设计里最容易被说混的一段，必须明确。
+
+### 6.1 哪些进入 chunk consolidation
+
+进入 chunk consolidation / AO / face culling 体系的只有：
+- 普通方块
+- `turret` 的底座和柱子
+- `zombieNest` 的结构方块
+- 轨道方块
+
+### 6.2 哪些不进入 chunk consolidation
+
+不进入 chunk consolidation 的有：
+- `turret` 的炮塔头、炮管、瞄准器
+- `minecart` 整体
+- `zombieNest` 的逻辑实体本身
+
+### 6.3 结论
+
+因此，`runtimeEntities` 不负责“把特殊形状塞回 blockData”。
+
+它负责的是：
+- 哪些逻辑/运行时实体应该存在
+- 这些实体恢复时需要哪些最小状态
+- 它们和 `blockData` 的依赖关系是什么
+
+而真正的视觉落地方式分三类：
+- **纯 blockData 渲染**：`zombieNest` 结构
+- **纯 runtime renderer 渲染**：`minecart`
+- **混合渲染**：`turret`
+
+---
+
+## 7. 必须新增的基础设施
+
+### 7.1 不能再让 Manager 直接操作 `WorldStore`
+
+修订后需要一个统一仓储层，例如：
+- `src/world/runtime-entities/RuntimeEntityRepository.js`
+
+它负责：
+- `loadChunkRuntimeEntities(cx, cz)`
+- `upsertEntity(ownerCx, ownerCz, entityRecord)`
+- `removeEntity(ownerCx, ownerCz, type, id)`
+- `moveEntity(fromCx, fromCz, toCx, toCz, entityRecord)`
+- `migrateLegacyEntitiesIfNeeded(cx, cz, legacySnapshot)`
+
+### 7.2 仓储层必须提供“按 chunk 串行化更新”
+
+必须新增类似接口：
+
+```js
+await runtimeEntityRepository.updateChunkRuntimeEntities(cx, cz, updater)
 ```
 
-- 现有 `finalizeNonDeferredPhase()` 中已有从 `pendingRuntimeEntities` 恢复的逻辑
-- 只需要确保 `_createFromWorldStore()` 正确填充该字段
-- 移除对旧 `persistenceService.cache` 的 fallback 读取
+要求：
+- 同一 chunk 的更新在仓储层串行化
+- `updater` 以最新 `runtimeEntities` 为输入
+- 返回新的 `runtimeEntities`
+- 避免 Manager 自己读改写造成覆盖
+
+### 7.3 必须新增活动实例生命周期 API
+
+三个 manager 都要补齐：
+- `activateChunkEntities(cx, cz, records)`
+- `deactivateChunkEntities(cx, cz, options)`
+- `serializeActiveEntity(instance)`
+- `deserializeEntity(record)`
+
+当前 `restoreXxxForChunk()` 只覆盖了“恢复”，没有对称的“卸载停用”语义，不够。
+
+---
+
+## 8. 旧机制兼容与迁移策略
+
+### 8.1 为什么不能直接删掉旧 `cache.entities`
+
+因为当前项目还存在 `Chunk.gen()` / `assembleEntityPhase()` 这条旧快照路径。只动 runtime-streaming 路径会导致：
+- 新生成 chunk 与纯加载 chunk 行为不一致
+- 旧存档、旧会话缓存无法被一次性迁移
+
+### 8.2 兼容原则
+
+第一阶段采取“双读单写”兼容：
+- **写入**：只写 `worldStore.runtimeEntities`
+- **读取**：优先读 `worldStore.runtimeEntities`，若为空，再读旧 `snapshot.entities` / `cache.entities` 做一次迁移
+
+### 8.3 迁移落点
+
+迁移动作必须集中在一个位置，不能散落在三个 manager 里。
+
+推荐：
+- 在 `RuntimeEntityRepository.migrateLegacyEntitiesIfNeeded()` 内完成
+- 完成后回写 `worldStore`
+- 再把旧 `cache.entities` 标记为已迁移或清空对应字段
+
+---
+
+## 9. WorldRuntime / WorldStore 协同规则
+
+### 9.1 `putChunkRecord` 必须改成字段级合并语义
+
+旧的全对象覆盖语义不再可接受。必须支持：
+- `blockData` 只更新 `blockData`
+- `runtimeEntities` 只更新 `runtimeEntities`
+- 两者互不覆盖
+
+### 9.2 `flushChunk` 只负责块工作集，不负责拼装实体状态
+
+`WorldRuntime.flushChunk()` 的职责应收敛为：
+- 把当前 chunk 的 `blockData / staticEntities / runtimeSeedData` 写回
+- 不直接拼接特殊实体运行时数据
+
+特殊实体状态由各自 manager 在以下时机独立更新：
+- 创建
+- 销毁
+- 跨 chunk 移动
+- 卸载前停用
+
+### 9.3 chunk 卸载前的顺序
+
+必须固定顺序：
+1. `minecartManager.deactivateChunkEntities()` 先停止并落盘
+2. 其他特殊实体 manager 执行停用
+3. `worldRuntime.flushBeforeUnload()` 写回方块工作集
+4. `chunk.dispose()`
+
+如果顺序反过来，就会再次出现“chunk 已经删了，flush 才开始读”的问题。
+

+## 10. 本次设计的推荐边界
+
+### 10.1 本次必须完成
+
+1. 三类实体统一迁移到 `worldStore.runtimeEntities`
+2. 新增统一仓储层，避免 Manager 直接改 `WorldStore`
+3. 明确激活/停用语义，补齐 chunk 卸载回收与恢复
+4. 打通 runtime-streaming 与旧 snapshot 路径的兼容桥
+5. 明确 `blockData` 与 `runtimeEntities` 的职责边界
+
+### 10.2 本次不做
 
-## 边界情况处理
+1. 把所有特殊实体都抽成通用 ECS
+2. 完全删除 `persistenceService.cache`
+3. 重写 `Chunk.gen()` 整条旧路径
+4. 把敌人、炮弹、掉落物也一起迁移到 runtimeEntities
 
-1. **矿车跨 chunk 移动**：从旧 chunk 移除 + 添加到新 chunk，两个 `putChunkRecord` 不原子。由于矿车已有稳定 `id`，恢复阶段在 `MinecartManager.restoreMinecartsForChunk()` 中按 `id` 全局去重（`this.minecarts.has(item.id)`），同一矿车不会重复实例化。
-2. **数据格式版本**：预留 `runtimeEntities.version` 字段，未来扩展时使用。
-3. **RegionRecord 不存在**：写入前检查 region 是否存在，不存在则跳过并 warn。
+---
 
-## 改动文件清单
+## 11. 设计结论
 
-| 文件 | 改动内容 |
-|------|---------|
-| `src/world/WorldStore.js` | `getChunkRecord`/`putChunkRecord` 支持 `runtimeEntities` 字段 |
-| `src/world/Chunk.js` | `_createFromWorldStore()` 读取 `runtimeEntities`，移除旧 cache fallback |
-| `src/actors/turret/TurretManager.js` | 写入路径改为 worldStore |
-| `src/actors/minecart/MinecartManager.js` | 写入路径改为 worldStore |
-| `src/actors/zombie-nest/ZombieNestManager.js` | 写入路径改为 worldStore |
+修订后的核心原则只有三条：
 
-## 后续工作（不在本次范围）
+1. **`IndexedDB / worldStore` 是唯一权威源，Manager 活动实例只是投影。**
+2. **特殊实体不能再按一种类型统一对待，必须区分“纯逻辑、纯渲染、混合渲染”。**
+3. **这个改造不是只改保存位置，而是要补齐 lifecycle、merge 语义、兼容桥和卸载恢复机制。**
 
-- chest（宝箱）和 lightSource（光源）的持久化
-- 实体运行时状态的完整持久化（速度、刷怪计数等）
+如果不先补这四个基础能力，继续按上一次的计划去 patch，只会反复掉进“局部看起来对，跑起来还是错”的循环。

 # Runtime Entities Persistence Implementation Plan
 
-> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
 
-**Goal:** Migrate turret, minecart, and zombie nest persistence from the old `persistenceService.cache` to WorldStore `RegionRecord.runtimeEntities`, ensuring entities survive chunk unload/reload cycles.
+**Goal:** 将 `turret`、`minecart`、`zombieNest` 从旧的 `persistenceService.cache.entities` 机制迁移到 `worldStore / IndexedDB` 权威模型，并补齐 chunk 卸载/恢复、渲染恢复、旧路径兼容、并发写入保护。
 
-**Architecture:** Add a `runtimeEntities` field to `RegionRecord.chunks[cx,cz]`. Entity managers write via `worldStore.putChunkRecord()`. Chunk reads via `getChunkRecord()` → `pendingRuntimeEntities` → `finalizeNonDeferredPhase()` restores instances.
+**Architecture:** 不再让各 Manager 直接 `getChunkRecord -> 改对象 -> putChunkRecord`。新增统一的 `RuntimeEntityRepository` 作为 `runtimeEntities` 的唯一写入入口；`blockData` 与 `runtimeEntities` 分层管理；活动实例采用“按 chunk 激活/停用”的显式生命周期。
 
-**Tech Stack:** JavaScript (ES Modules), IndexedDB via PersistenceWorker, WorldStore/RegionRecord architecture
+**Tech Stack:** JavaScript (ES Modules), `WorldStore`, `WorldRuntime`, IndexedDB Worker RPC, Three.js, 现有 Chunk 装配与 Instanced 渲染体系

-### Task 1: WorldStore — 在 getChunkRecord/putChunkRecord 中支持 runtimeEntities
+## 先决原则
+
+### 必须遵守
+- `worldStore / IndexedDB` 是权威源，`persistenceService.cache` 只是兼容桥和工作缓存。
+- 任何新逻辑不得只写旧 `cache.entities`。
+- 不能直接在三个 Manager 内部分散实现 chunkRecord 读改写。
+- 必须同时验证两条装载链路：
+  - `WorldRuntime.ensureChunkData()` -> `Chunk.loadFromRecord()`
+  - `Chunk.gen()` / `assembleEntityPhase()` 的旧快照路径
+
+### 本计划不接受的“伪完成”
+- 仅修改 `Chunk.loadFromRecord()`
+- 仅给 `WorldStore.getChunkRecord()` 加字段
+- 只让实体“刷新页面能恢复”，但 chunk 卸载/恢复仍异常
+- 只验证 minecart，不验证 turret / zombieNest
+
+---
+
+### Task 1: 代码路径盘点与契约冻结
 
 **Files:**
-- Modify: `src/world/WorldStore.js:124-165`
-- Test: 浏览器中验证
-
-**Step 1: 修改 getChunkRecord 返回值**
-
-在 `src/world/WorldStore.js` 的 `getChunkRecord` 方法（约第124行）中，返回对象增加 `runtimeEntities` 字段：
-
-```javascript
-// 当前返回：
-return {
-  cx,
-  cz,
-  blockData: chunkData.blockData || {},
-  staticEntities: chunkData.staticEntities || [],
-  runtimeSeedData: chunkData.runtimeSeedData || {}
-};
-
-// 修改为：
-return {
-  cx,
-  cz,
-  blockData: chunkData.blockData || {},
-  staticEntities: chunkData.staticEntities || [],
-  runtimeEntities: chunkData.runtimeEntities || null,
-  runtimeSeedData: chunkData.runtimeSeedData || {}
-};
-```
+- Modify: `docs/plans/2026-04-28-runtime-entities-persistence-design.md`

+- Reference: `src/actors/zombie-nest/ZombieNestManager.js`
 
-同样修改 `getChunkRecordsInRegion` 方法（约第147行）中对应的返回对象，也增加 `runtimeEntities` 字段。
+- [ ] **Step 1: 冻结数据职责边界**
 
-**Step 2: 修改 putChunkRecord 接受 runtimeEntities**
+确认并记录：
+- `blockData` 管结构方块、普通方块、轨道、consolidation、AO
+- `runtimeEntities` 管逻辑实体元数据与最小行为状态
+- manager 活动实例不是权威持久化数据
 
-`putChunkRecord` 方法（约第178行）直接接收 `chunkRecord` 对象并写入 `region.chunks[key] = chunkRecord`。由于是全对象覆盖写入，只要调用方传入 `runtimeEntities` 字段，自动就会被保存。**无需修改代码**，只需要在文档中确认该字段会被透传。
+- [ ] **Step 2: 冻结三类实体的最小持久化字段**
 
-**Step 3: 确认无需改动**
+整理为最终契约：
+- `turret`: `id`、`ownerChunk`、`anchor`、`renderState.yaw/pitch`、关键支撑块
+- `minecart`: `id`、`ownerChunk`、`anchor`、`orientation`、`movementState`、`lastTrackPosition`、`linkedMinecartIds`
+- `zombieNest`: `id`、`ownerChunk`、`anchor`、`criticalBlock`、`lastSpawnAt`
 
-- `saveRegionRecord` 和 `saveRegionRecordsBatch` 是直接序列化整个 region 对象，`runtimeEntities` 自动包含
-- PersistenceWorker 的 `saveRegionRecord` handler 也是直接 `store.put({ regionKey, data: record })`，自动序列化所有字段
+- [ ] **Step 3: 明确本次兼容策略**
 
-**Step 4: Commit**
+确认采用：
+- 写：只写 `worldStore.runtimeEntities`
+- 读：优先 `worldStore.runtimeEntities`，必要时迁移旧 `cache.entities`
 
-```bash
-git add src/world/WorldStore.js
-git commit -m "feat(worldstore): add runtimeEntities field to getChunkRecord projection"
-```
+- [ ] **Step 4: 人工检查设计文档与计划文档是否一致**
+
+检查目标、边界、字段与生命周期是否完全一致，不允许文档内部互相矛盾。

+这里不能简单删除旧逻辑；要改成兼容桥：
+- 若 `pendingRuntimeEntities` 已有 `worldStore` 数据，则直接使用
+- 若 `worldStore` 为空但旧 `snapshot.entities` / `cache.entities` 有值，则走迁移流程

-  const cx = Math.floor(entry.position.x / PERSISTENCE_CONFIG.CHUNK_SIZE);
-  const cz = Math.floor(entry.position.z / PERSISTENCE_CONFIG.CHUNK_SIZE);

-### Task 5: ZombieNestManager — 写入路径迁移到 WorldStore
+### Task 7: 兼容迁移旧 `cache.entities` / 旧存档数据
 
 **Files:**
-- Modify: `src/actors/zombie-nest/ZombieNestManager.js:100-177` (ensureChunkSnapshot, saveNestToSnapshot, removeNestFromSnapshot)
-- Test: 浏览器中放置/销毁巢穴，刷新页面验证巢穴保留
-
-**Step 1: 添加 worldStore 注入**
-
-```javascript
-/**
- * 获取 worldStore（优先测试注入）
- * @returns {object|null}
- */
-getWorldStore() {
-  return globalThis._worldStore || this.world?.worldStore || null;
-}
+- Modify: `src/world/runtime-entities/RuntimeEntityRepository.js`
+- Modify: `src/services/PersistenceService.js`（如需要迁移辅助）
+- Modify: `src/world/Chunk.js`
+- Modify: `src/core/Game.js`（若旧手动存档恢复逻辑需要桥接）
+
+- [ ] **Step 1: 实现旧 `entities` 结构到新 `runtimeEntities` 的转换器**
+
+输入示例：
+```js
+{ turrets: [...], minecarts: [...], zombieNests: [...] }
 ```
 
-**Step 2: 替换 saveNestToSnapshot**
-
-替换现有方法（约第139-155行）：
-
-```javascript
-/**
- * 将巢穴写入 WorldStore
- * @param {ZombieNest} nest
- * @returns {void}
- */
-async saveNestToSnapshot(nest) {
-  const worldStore = this.getWorldStore();
-  if (!worldStore) return;
-  const entry = this.toNestSnapshot(nest);
-  if (!entry) return;
-
-  const cx = Math.floor(entry.position.x / PERSISTENCE_CONFIG.CHUNK_SIZE);
-  const cz = Math.floor(entry.position.z / PERSISTENCE_CONFIG.CHUNK_SIZE);
-
-  const chunkRecord = await worldStore.getChunkRecord(cx, cz);
-  if (!chunkRecord) return;
-
-  if (!chunkRecord.runtimeEntities) chunkRecord.runtimeEntities = {};
-  if (!Array.isArray(chunkRecord.runtimeEntities.zombieNests)) {
-    chunkRecord.runtimeEntities.zombieNests = [];
-  }
-
-  const list = chunkRecord.runtimeEntities.zombieNests;
-  const posKey = this.getPositionKey(entry.position);
-  const idx = list.findIndex(item => this.getPositionKey(item.position) === posKey);
-  if (idx >= 0) list[idx] = entry;
-  else list.push(entry);
-
-  await worldStore.putChunkRecord(cx, cz, chunkRecord);
-}
+输出示例：
+```js
+{ version: 1, byType: { turrets: [...], minecarts: [...], zombieNests: [...] } }
 ```
 
-**Step 3: 替换 removeNestFromSnapshot**
+- [ ] **Step 2: 只在新权威记录缺失时触发迁移**
 
-替换现有方法（约第162-177行）：
+避免旧数据覆盖新数据。
 
-```javascript
-/**
- * 从 WorldStore 中移除巢穴
- * @param {ZombieNest} nest
- * @returns {void}
- */
-async removeNestFromSnapshot(nest) {
-  const worldStore = this.getWorldStore();
-  if (!worldStore) return;
-  const entry = this.toNestSnapshot(nest);
-  if (!entry) return;
+- [ ] **Step 3: 完成一次迁移后写回 worldStore**
 
-  const cx = Math.floor(entry.position.x / PERSISTENCE_CONFIG.CHUNK_SIZE);
-  const cz = Math.floor(entry.position.z / PERSISTENCE_CONFIG.CHUNK_SIZE);
+并考虑清理旧字段，至少避免下一次再次重复迁移。
 
-  const chunkRecord = await worldStore.getChunkRecord(cx, cz);
-  if (!chunkRecord?.runtimeEntities?.zombieNests) return;
+- [ ] **Step 4: 检查 `Game` 的旧恢复入口**
 
-  const posKey = this.getPositionKey(entry.position);
-  chunkRecord.runtimeEntities.zombieNests = chunkRecord.runtimeEntities.zombieNests.filter(
-    item => this.getPositionKey(item.position) !== posKey
-  );
+[Game.js](/Users/bachi/jaylli/mc-lite/src/core/Game.js) 仍有从 `saveData.worldDeltas[].entities` 恢复特殊实体的逻辑；需要决定：
+- 是继续保留为旧存档入口
+- 还是统一先转成新 `runtimeEntities` 再恢复
 
-  await worldStore.putChunkRecord(cx, cz, chunkRecord);
-}
-```
+本次推荐后者，避免运行时再维护两套恢复逻辑。
 
-**Step 4: 删除 ensureChunkSnapshot 方法**
+- [ ] **Step 5: Run lint**
 
-删除 `ensureChunkSnapshot` 方法（约第100-114行）。
+Run: `npm run lint`  
+Expected: PASS
 
-**Step 5: Run lint**
+---
 
-```bash
-npm run lint
-```
+### Task 8: 回归验证矩阵
 
-**Step 6: Commit**
+**Files:**
+- Test: 浏览器手工验证
+- Test: `src/tests/index.html`（如已有可复用测试）
+- Optional Modify: 新增最小测试入口或 debug 命令
 
-```bash
-git add src/actors/zombie-nest/ZombieNestManager.js
-git commit -m "feat(zombie-nest): migrate persistence to WorldStore runtimeEntities"
-```
+- [ ] **Step 1: 验证 turret 完整链路**
+
+手工验证：
+1. 放置炮塔
+2. 刷新页面后仍存在
+3. 跑远触发 chunk 卸载，再回来恢复
+4. 破坏关键 obsidian 后权威记录被删除
+5. 再次刷新页面不会“复活”幽灵炮塔
+
+- [ ] **Step 2: 验证 zombieNest 完整链路**
+
+手工验证：
+1. 放置巢穴
+2. 结构方块正常进入 chunk 渲染
+3. 跑远卸载后，回来结构方块恢复、逻辑实例恢复
+4. 刷怪节奏不因卸载/恢复被重置
+5. 破坏关键方块后不会残留幽灵记录
+
+- [ ] **Step 3: 验证 minecart 完整链路**
+
+手工验证：
+1. 放置轨道和矿车
+2. 运动中跑远卸载，回来后位置和状态合理
+3. 拾取/爆炸后记录删除
+4. 跨 chunk 运动后不重复、不丢失
+5. 联动矿车关系恢复正确
+
+- [ ] **Step 4: 验证双装载路径一致性**
+
+验证以下两种情况下行为一致：
+- 纯 runtime-streaming 从 `worldStore` 读回
+- 仍经 `Chunk.gen()` / 旧快照桥恢复
+
+- [ ] **Step 5: 执行 lint**
+
+Run: `npm run lint`  
+Expected: PASS
+
+- [ ] **Step 6: 浏览器测试**
+
+Run: `npm run start`  
+Then open: `http://localhost:8080/src/tests/index.html`  
+Expected: 现有测试不回归；若无相关自动测试，至少确认页面可正常加载并进行手工场景验证

+3. `blockData` 与 `runtimeEntities` 的边界清晰，没有互相覆盖。
+4. `WorldRuntime.flushChunk()` 与实体写入不再互相打架。
+5. 旧 `cache.entities` 只作为迁移桥，不再是常规写入路径。
+6. 三类实体都通过“刷新页面 + 跑远卸载 + 返回恢复 + 破坏/拾取删除”的手工回归。

-# Runtime Entities Persistence Design
+# Runtime Special Entities Session Persistence Design
 
 **日期**: 2026-04-28  
-**状态**: 修订版  
-**范围**: `turret`、`minecart`、`zombieNest` 在 `worldStore / IndexedDB` 权威存储机制下的持久化、恢复、卸载与渲染协同
+**状态**: 修订版 v2  
+**本阶段目标**: 先修复 runtime 会话期内的特殊实体与相关结构方块在 chunk 卸载/重载后的正确性；暂不把特殊实体正式纳入 `worldStore / IndexedDB` 权威链路。
 
-## 1. 这次失败暴露出的根因
-
-上一次方案失败，不是因为少改了几行，而是因为设计抽象层级错了。它把三类“特殊实体”都当成了同一种 `runtimeEntities` 数据迁移问题，但真实代码里三者的渲染形态、与 `blockData` 的关系、卸载语义、恢复入口都不同。
+---
 
-失败点主要有四类：
+## 1. 结论先行
 
-1. **把特殊实体错误地视为纯元数据对象**
-   - `zombieNest` 没有独立视觉模型，视觉主体是结构方块，实体实例只负责刷怪与完整性检查。
-   - `minecart` 没有落地到 `blockData`，完全是运行时对象，由独立 Instanced Renderer 渲染。
-   - `turret` 是混合体：底座/柱子是方块，炮塔头部是独立 Three.js 对象。
+这次失败，核心不是“特殊实体恢复代码少写了几行”，而是阶段目标和真实架构被混淆了。
 
-2. **只考虑了 `Chunk.loadFromRecord()`，没考虑另一条真实装载链路**
-   - 当前项目至少有两条恢复路径：
-     - `WorldRuntime.ensureChunkData()` -> `Chunk.loadFromRecord()`
-     - `Chunk.gen()` / `assembleEntityPhase()` 通过 `persistenceService.cache` 合并快照
-   - 只改第一条路径，第二条路径仍然读旧数据，会导致行为不一致。
+当前分支里，特殊实体并没有真正迁移到 `worldStore`：
 
-3. **直接让各 Manager 自己 `getChunkRecord -> 改对象 -> putChunkRecord`，没有解决并发覆盖**
-   - `WorldRuntime.flushChunk()`、`flushAllDirty()`、Manager 写入、chunk 卸载前写回，都会碰同一个 `chunkRecord`。
-   - 没有一个“按 chunk 串行化”的更新接口，读改写天然存在竞态。
+1. `worldStore / WorldRuntime` 当前只承接 `blockData / staticEntities / runtimeSeedData`
+2. 炮塔、丧尸巢穴、矿车的 runtime 快照仍然主要保存在 `persistenceService.cache.get(chunkKey).entities`
+3. `Chunk.loadFromRecord()` 恢复运行时实体时，实际仍然要去合并 `persistenceService.cache.entities`
 
-4. **没有定义实体“激活态”和“持久态”的边界**
-   - 当前代码里，特殊实体大多是全局 manager 持有的活动实例；chunk 卸载并不天然等于实体实例销毁。
-   - 方案没有明确：远离后是“继续活着但不可见”，还是“按 chunk 停用，靠近再恢复”。
+因此，第一阶段不应该继续硬推“特殊实体 -> IndexedDB 权威化”。正确收敛方式是：
 
-本次修订要先把这四个问题讲清楚，再谈实现计划。
+1. `worldStore` 继续负责普通方块和结构方块的持久化镜像
+2. 特殊实体 runtime 数据先继续以 **内存会话级快照** 为权威
+3. 先把 chunk 卸载/重载期间的内存正确性、方块正确性、交互正确性修通
+4. 后续再单独做“特殊实体正式入库”的第二阶段设计
 
 ---
 
-## 2. 现状澄清：三类特殊实体并不等价
+## 2. 本次失败的真实根因
+
+### 2.1 方块侧状态在 chunk 卸载时丢失
+
+你复现里“铁轨方块消失、炮塔底座/巢穴结构不回来、矿车还在”这一组现象，已经说明第一根因在 **结构方块没有正确保住**。
+
+当前 `runtime-streaming` 路径里：
+
+1. 玩家放置/删除方块时，`World.setBlock()` / `World.removeBlock()` 只标记 `worldRuntime.markChunkDirty()`
+2. 真正写回 `worldStore` 依赖 `WorldRuntime.flushChunk()`
+3. chunk 卸载时，`World.update()` 里调用了 `this.worldRuntime.flushBeforeUnload(chunk.cx, chunk.cz).catch(() => {})`
+4. 但这一步 **没有 await**
+5. 紧接着就 `scene.remove(chunk.group)`、`chunk.dispose()`、`this.chunks.delete(key)`
+6. `flushChunk()` 内部又要从 `this._world.chunks.get(key)` 重新取活动 chunk
+
+结果就是：
+
+1. 卸载流程先把活动 chunk 销毁了
+2. 异步 flush 再执行时，活动 chunk 可能已经不存在
+3. `blockData` 没有成功写回
+4. 重新回来时，铁轨、炮塔底座、巢穴结构方块丢失
+
+这正好解释了为什么：
+
+1. `minecart` 还能出现，因为它走的是独立 runtime 快照
+2. `sand_train_track`、`turret` 底座、`zombieNest` 结构没回来，因为它们本质上是方块侧状态
 
-### 2.1 `turret`
+### 2.2 炮塔/巢穴“看起来像恢复失败”，实际上是结构先丢，再自毁
 
-代码事实：
-- 放置时先往世界写入底座与柱子方块，再创建 `Turret` 实例。见 [TurretPlacementHandler.js](/Users/bachi/jaylli/mc-lite/src/actors/turret/TurretPlacementHandler.js) 。
-- `Turret` 自己再创建炮塔头部、炮管等独立 `Three.js` 对象，直接挂到 `scene`，不属于 chunk mesh。见 [Turret.js](/Users/bachi/jaylli/mc-lite/src/actors/turret/Turret.js) 。
-- 完整性校验依赖世界中的关键方块是否仍存在。
+当前炮塔和丧尸巢穴都还是旧模型：
 
-结论：
-- `turret` 不是“只要恢复一条 runtimeEntities 记录就够了”。
-- 它同时依赖两套数据：
-  - `blockData`：底座/柱子，是视觉与物理的一部分
-  - `runtimeEntities`：炮塔头部逻辑、朝向、生命周期
+1. manager 全局持有活动实例
+2. chunk 卸载时并不会显式停用它们
+3. 远离时完整性检查会跳过未加载 chunk，避免误杀
+4. 玩家跑回来后，如果结构方块不存在，它们会在完整性检查中判定失效并自毁
 
-### 2.2 `zombieNest`
+所以现象不是“恢复入口单点失效”，而是：
 
-代码事实：
-- 放置时先生成并落地方块结构，再创建 `ZombieNest` 实例。见 [ZombieNestPlacementHandler.js](/Users/bachi/jaylli/mc-lite/src/actors/zombie-nest/ZombieNestPlacementHandler.js) 。
-- `ZombieNest` 本身没有独立 mesh；它只是逻辑体，依赖 `criticalBlock` 做完整性校验，并定时刷怪。见 [ZombieNest.js](/Users/bachi/jaylli/mc-lite/src/actors/zombie-nest/ZombieNest.js) 。
+1. 结构方块先丢
+2. chunk 重新加载后可查询
+3. 炮塔/巢穴发现关键方块没了
+4. 实例自毁
 
-结论：
-- `zombieNest` 的“渲染恢复”主要是结构方块通过 chunk 正常加载、consolidation、AO 刷新后重新显示。
-- `runtimeEntities` 里保存的是逻辑实体，而不是视觉主体。
+### 2.3 计划边界错了：第一阶段不该把特殊实体权威源直接切到 IndexedDB
 
-### 2.3 `minecart`
+当前代码现实是：
 
-代码事实：
-- 矿车不写结构方块，只依赖轨道方块存在。
-- 渲染完全由 `MinecartInstancedRenderer` 负责；`Minecart` 只是数据对象。见 [Minecart.js](/Users/bachi/jaylli/mc-lite/src/actors/minecart/Minecart.js) 与 [MinecartManager.js](/Users/bachi/jaylli/mc-lite/src/actors/minecart/MinecartManager.js) 。
-- 卸载 chunk 前已有 `stopMinecartsForChunk()` 逻辑，会停止运动并写快照。
+1. `WorldStore.getChunkRecord()` 不返回 `runtimeEntities`
+2. `WorldStore.putChunkRecord()` 也不处理 `runtimeEntities`
+3. `WorldRuntime.ensureChunkData()` 只返回 `blockData / staticEntities / runtimeSeedData`
+4. `Chunk.loadFromRecord()` 仍然要回头去看 `persistenceService.cache.entities`
 
-结论：
-- `minecart` 是最接近“纯 runtime entity”的对象。
-- 但它又依赖轨道方块这一外部支撑条件，不能脱离 `blockData` 单独看。
+这说明“特殊实体已迁入 worldStore”并不成立。
+
+如果在这个基础上继续设计 `RuntimeEntityRepository + IndexedDB authority`，会把第一阶段问题复杂化，甚至把真正 bug 淹没掉。

-## 3. 修订后的权威模型
+## 3. 现状下，特殊实体到底怎么存、怎么取
 
-### 3.1 三层真相来源
+这一节只描述当前代码事实。
 
-在新的 `worldStore` 机制下，必须严格区分三层：
+### 3.1 炮塔 `turret`
 
-1. **IndexedDB / RegionRecord**
-   - 唯一权威持久化数据源
-   - 保存 `blockData`、`staticEntities`、`runtimeSeedData`、`runtimeEntities`
+**存储方式**
 
-2. **Chunk runtime working set**
-   - 当前已加载 chunk 的内存工作集
-   - `blockData Map`、可见面、AO、consolidation 状态属于这一层
-   - 不是权威，只是权威数据的活动投影
+1. 放置时，`TurretPlacementHandler.place()` 先调用 `world.setBlock()` 放置 3x3 `iron_ore` 底座和 2 格 `obsidian` 柱子
+2. 然后调用 `turretManager.createTurret()`
+3. `TurretManager.saveTurretToSnapshot()` 把炮塔快照写进 `persistenceService.cache.get(chunkKey).entities.turrets`
 
-3. **Manager active instances**
-   - `turretManager.turrets`
-   - `minecartManager.minecarts`
-   - `zombieNestManager.nests`
-   - 这些实例是“活动态对象”，不是权威数据源
+**取回方式**
 
-### 3.2 `persistenceService.cache` 的新定位
+1. chunk 重载时，`Chunk.loadFromRecord()` 先从 `worldStore` 读回 `blockData`
+2. 然后再从 `persistenceService.cache.get(chunkKey).entities` 合并 `turrets`
+3. `finalizeNonDeferredPhase()` 调 `turretManager.restoreTurretsForChunk()`
+4. manager 直接重新 `createTurret(..., persist:false)`
 
-`persistenceService.cache` 不能再被视为权威来源。
+**关键事实**
 
-修订后它只能有两个用途：
+1. 炮塔头部渲染是独立 Three.js 对象，不属于 chunk mesh
+2. 炮塔完整性依赖 `obsidian` 柱子仍然存在
+3. 结构方块丢失时，炮塔会在完整性检查中销毁自己
 
-1. **旧装载路径兼容桥**
-   - 仍在 `Chunk.gen()` / `assembleEntityPhase()` 中存在时，可作为临时桥接层
+### 3.2 丧尸巢穴 `zombieNest`
 
-2. **会话级工作缓存**
-   - 用于旧代码尚未清理前避免大范围重构
+**存储方式**
 
-必须禁止的事情：
-- 新业务状态继续只写 `cache` 不写 `worldStore`
-- `cache` 覆盖 `worldStore` 权威值
-- 不经统一合并策略直接从多个入口并发写 `cache` 和 `worldStore`
+1. `ZombieNestPlacementHandler.place()` 先把整套结构方块写进世界
+2. 然后 `zombieNestManager.createNest()`
+3. `ZombieNestManager.saveNestToSnapshot()` 把逻辑快照写进 `persistenceService.cache.get(chunkKey).entities.zombieNests`
 
----
+**取回方式**
 
-## 4. 新的数据模型
-
-### 4.1 `ChunkRecord.runtimeEntities`
-
-不再继续沿用“若干松散数组 + Manager 自己拼字段”的做法。修订后统一成带版本号的结构。
-
-```js
-chunkRecord.runtimeEntities = {
-  version: 1,
-  byType: {
-    turrets: [
-      {
-        id: 'turret_xxx',
-        ownerChunk: 'cx,cz',
-        anchor: { x, y, z },
-        renderState: {
-          yaw: number,
-          pitch: number
-        },
-        support: {
-          kind: 'turret_base',
-          criticalBlocks: [
-            { x, y, z, type: 'obsidian' },
-            { x, y, z, type: 'obsidian' }
-          ]
-        }
-      }
-    ],
-    minecarts: [
-      {
-        id: 'minecart_xxx',
-        ownerChunk: 'cx,cz',
-        anchor: { x, y, z },
-        motionState: {
-          orientation: number,
-          movementState: 'IDLE' | 'MOVING_FORWARD' | 'MOVING_BACKWARD',
-          lastTrackPosition: { x, y, z } | null
-        },
-        linkState: {
-          linkedMinecartIds: []
-        },
-        support: {
-          kind: 'track',
-          trackBlock: { x, y, z }
-        }
-      }
-    ],
-    zombieNests: [
-      {
-        id: 'zombie_nest_xxx',
-        ownerChunk: 'cx,cz',
-        anchor: { x, y, z },
-        criticalBlock: { x, y, z, type },
-        spawnState: {
-          lastSpawnAt: number
-        }
-      }
-    ]
-  }
-}
-```
-
-### 4.2 为什么需要 `id`
-
-旧方案里 `turret` / `zombieNest` 用位置去重，`minecart` 才有稳定 `id`。这不够。
-
-必须统一要求三类实体都有稳定 `id`，原因：
-- 支持 chunk 卸载/恢复时识别“同一个实体”
-- 避免位置微调、朝向变化、特殊交互导致误判为新对象
-- 为未来支持跨 chunk 迁移、调试追踪、链路日志打基础
-
-### 4.3 为什么要保存比“位置+朝向”更多的状态
-
-上次设计要求“只保存基础属性（位置+朝向）”，这个结论对当前系统不成立。
-
-至少要保留：
-- `minecart.lastTrackPosition`：否则回弹与停止位置会漂
-- `minecart.linkedMinecartIds`：否则重载后联动车组关系丢失
-- `zombieNest.lastSpawnAt`：否则玩家可以通过卸载/加载重置刷怪节奏
-- `turret.yaw / pitch`：否则恢复时炮塔头部突兀跳回默认朝向
-
-不必保存的状态：
-- `turret` 炮弹对象
-- `zombieNest` 当前已生成的敌人引用
-- `minecart` 临时速度向量（可选，第一期可以不保）
+1. chunk 重载时，结构方块先从 `blockData` 恢复
+2. `Chunk.loadFromRecord()` 再从 `persistenceService.cache.entities` 提取 `zombieNests`
+3. `finalizeNonDeferredPhase()` 调 `zombieNestManager.restoreNestsForChunk()`
 
----
+**关键事实**
+
+1. 巢穴没有独立 mesh
+2. 真正“看得见”的部分是结构方块
+3. runtime 快照只保存逻辑实体
+4. 关键方块缺失时，巢穴会在完整性检查中自毁
+
+### 3.3 矿车 `minecart`
 
-## 5. 统一生命周期设计
+**存储方式**
 
-### 5.1 持久态 vs 激活态
+1. 矿车本身不写结构方块
+2. `MinecartManager.saveMinecartToSnapshot()` 把矿车数据写进 `persistenceService.cache.get(chunkKey).entities.minecarts`
+3. chunk 卸载前 `stopMinecartsForChunk()` 会停止运动并再次保存
 
-修订后，所有特殊实体都遵循同一个生命周期：
+**取回方式**
 
-1. **持久态记录存在于 `worldStore`**
-2. **chunk 进入激活范围后，Manager 基于记录创建活动实例**
-3. **chunk 卸载时，活动实例被停用/销毁，但持久态记录保留**
-4. **再次进入范围时，再从持久态记录恢复活动实例**
+1. chunk 重载时，`Chunk.loadFromRecord()` 从 `persistenceService.cache.entities.minecarts` 取出快照
+2. `finalizeNonDeferredPhase()` 调 `minecartManager.restoreMinecartsForChunk()`
+
+**关键事实**
+
+1. 矿车是独立 runtime 对象
+2. 它依赖轨道存在，但当前没有像炮塔/巢穴那样的完整性自毁链路
+3. 所以轨道丢失时，矿车仍可能“还在”
+
+---
 
-这意味着：
-- 不能再依赖“实例一直挂在 manager 里，远离也不回收”的隐式行为
-- 必须把“按 chunk 激活/停用”设计成显式 API
+## 4. 第一阶段修正后的权威模型
 
-### 5.2 放置流程
+### 4.1 本阶段明确放弃的目标
 
-#### `turret`
-1. 通过 `world.setBlock()` 写入底座与柱子到 `blockData`
-2. 写入或更新 `runtimeEntities.byType.turrets`
-3. 若 owner chunk 当前已激活，则创建 `Turret` 实例并挂 scene
+以下内容全部推迟到第二阶段，不纳入当前方案：
 
-#### `zombieNest`
-1. 通过结构 loader 落地巢穴方块到 `blockData`
-2. 写入 `runtimeEntities.byType.zombieNests`
-3. 若 owner chunk 已激活，则创建 `ZombieNest` 逻辑实例
+1. 把 `turret / zombieNest / minecart` 正式持久化进 IndexedDB
+2. 为特殊实体新建 `worldStore.runtimeEntities`
+3. 用 `RuntimeEntityRepository` 统一所有持久态实体读写
+4. 把所有特殊实体都改成“按 chunk 激活/停用”的新生命周期
 
-#### `minecart`
-1. 校验轨道方块存在
-2. 写入 `runtimeEntities.byType.minecarts`
-3. 若 owner chunk 已激活，则创建 `Minecart` 实例并让 instanced renderer 纳入渲染
+这些都不是当前 bug 的最短修复路径。
 
-### 5.3 chunk 卸载流程
+### 4.2 本阶段的三层数据职责
 
-这是上次方案完全没定义清楚的部分。
+修正后，本阶段应该采用下面这套职责边界：
 
-修订后要求：
+1. **活动 chunk 内方块权威**
+   - `chunk.blockData`
+   - 玩家放置、删除、结构生成、consolidation、AO 都围绕它工作
 
-#### `turret`
-- 卸载 owner chunk 前，销毁炮塔活动实例的独立视觉对象
-- **不得删除 `runtimeEntities` 记录**
-- **不得删除底座/柱子 `blockData`**
+2. **会话级 chunk 快照权威**
+   - `persistenceService.cache`
+   - `cache.blocks` 保存运行期内存中的 chunk 方块快照
+   - `cache.entities` 保存特殊实体 runtime 快照
+   - 这是“chunk 卸载后，再回来还能恢复”的第一权威
 
-#### `zombieNest`
-- 卸载 owner chunk 前，销毁逻辑实例
-- 结构方块会随着 chunk 自身卸载而消失，无需额外清理
-- **不得删除 `runtimeEntities` 记录**
+3. **worldStore / IndexedDB**
+   - 本阶段只作为普通方块和结构方块的异步镜像
+   - 它很重要，但不能成为 runtime 卸载/回流的唯一立即依赖
 
-#### `minecart`
-- 先停止运动、落盘最新状态
-- 再销毁活动实例
-- **不得删除 `runtimeEntities` 记录**
+### 4.3 第一阶段的关键原则
 
-### 5.4 chunk 恢复流程
+#### 原则 A：特殊实体 runtime 权威仍然是 `persistenceService.cache.entities`
 
-恢复必须放在 chunk 地形/方块准备完成之后，否则完整性检查和依赖方块查询会读到不完整状态。
+也就是继续复用旧机制，只做兼容修补，不做架构跳跃。
 
-统一顺序：
-1. `blockData` 注入
-2. 普通方块 mesh / consolidation 基础准备完成
-3. `runtimeEntities` 进入 `pendingRuntimeEntities`
-4. `finalizeNonDeferredPhase()` 或等价阶段调用 manager 的 `restoreForChunk()`
+#### 原则 B：chunk 卸载前必须先把当前 `blockData` 同步成会话快照
 
-### 5.5 交互删除 / 结构损坏流程
+哪怕 `worldStore` 异步 flush 失败，只要内存会话还活着，重新回来也必须能从快照恢复。
 
-#### `turret`
-- 若关键柱子被破坏，活动实例销毁
-- 同步删除其 `runtimeEntities` 记录
-- 底座/残余方块是否保留，按当前玩法决定；第一期保持现状，只删除逻辑实体记录
+#### 原则 C：`worldStore` 在本阶段只负责“块级镜像”，不是特殊实体的立即权威源
 
-#### `zombieNest`
-- 若 `criticalBlock` 被破坏，活动实例销毁
-- 同步删除 `runtimeEntities` 记录
-- 结构残骸是否自动清理，不属于本次持久化改造范围
+特殊实体后续是否持久化到 IndexedDB，可以下一阶段再决定。
 
-#### `minecart`
-- 拾取/爆炸/碰撞销毁时，删除 `runtimeEntities` 记录
-- 轨道方块仍由普通 `blockData` 自己管理
+#### 原则 D：第一阶段不强行改炮塔/巢穴生命周期
+
+保持旧行为：
+
+1. 炮塔、巢穴实例仍由 manager 全局持有
+2. 远离 chunk 时不主动销毁
+3. 近处 chunk 恢复后依靠结构方块继续保持正确性
+
+只有矿车保留现有 `stopMinecartsForChunk()` 行为。
 
 ---
 
-## 6. 渲染与 consolidation 的正确关系
+## 5. 第一阶段推荐设计
 
-这是本次设计里最容易被说混的一段，必须明确。
+### 5.1 引入“会话快照桥”，而不是“runtimeEntities 入库”
 
-### 6.1 哪些进入 chunk consolidation
+需要新增一个很轻量的会话桥接层，职责只有两件事：
 
-进入 chunk consolidation / AO / face culling 体系的只有：
-- 普通方块
-- `turret` 的底座和柱子
-- `zombieNest` 的结构方块
-- 轨道方块
+1. 把 `worldStore` 读出的 `blockData` 注入到 `persistenceService.cache.blocks`
+2. 把活动 chunk 当前的 `blockData` 回写到 `persistenceService.cache.blocks`
 
-### 6.2 哪些不进入 chunk consolidation
+它不应该承担：
 
-不进入 chunk consolidation 的有：
-- `turret` 的炮塔头、炮管、瞄准器
-- `minecart` 整体
-- `zombieNest` 的逻辑实体本身
+1. 新的实体仓储抽象
+2. region 级并发调度
+3. IndexedDB 事务性 runtime entity 写入
 
-### 6.3 结论
+### 5.2 `persistenceService.cache` 需要重新被视为“runtime session overlay”
 
-因此，`runtimeEntities` 不负责“把特殊形状塞回 blockData”。
+本阶段要明确：
 
-它负责的是：
-- 哪些逻辑/运行时实体应该存在
-- 这些实体恢复时需要哪些最小状态
-- 它们和 `blockData` 的依赖关系是什么
+1. `cache.blocks` 不再只是旧时代遗留
+2. 它是 runtime-streaming 阶段 **chunk 卸载后再恢复** 的会话级数据源
+3. `cache.entities` 继续承担炮塔、巢穴、矿车的 runtime 快照
 
-而真正的视觉落地方式分三类：
-- **纯 blockData 渲染**：`zombieNest` 结构
-- **纯 runtime renderer 渲染**：`minecart`
-- **混合渲染**：`turret`
+### 5.3 `Chunk.loadFromRecord()` 的正确行为
 
----
+从现在起，`Chunk.loadFromRecord()` 的职责应该变成：
+
+1. 先拿 `worldStore` 提供的基础 `chunkRecord`
+2. 立即确保 `persistenceService.cache[chunkKey]` 存在
+3. 若 cache 里已经有更新过的 `blocks`，则以 cache 为准覆盖基础 `blockData`
+4. `entities` 仍然只从 cache 读取
+5. 把最终结果注入 chunk，再走现有 finalize 恢复逻辑
+
+这一步的关键不是“把特殊实体搬到 worldStore”，而是“让旧的 session 快照机制在新 worldStore 路径上继续工作”。
+
+### 5.4 chunk 卸载的正确顺序
+
+当前顺序不安全，应该改成：
+
+1. 先把当前 `chunk.blockData` 同步到 `persistenceService.cache.blocks`
+2. 再处理矿车 `stopMinecartsForChunk()`
+3. 再触发 `worldRuntime.flushBeforeUnload()` 或等价 flush
+4. flush 至少要保证“内存会话快照已完成”
+5. 然后才允许 `chunk.dispose()` 和 `this.chunks.delete(key)`
 
-## 7. 必须新增的基础设施
+如果需要继续异步写 `worldStore`，也必须在“会话快照已完成”之后。
 
-### 7.1 不能再让 Manager 直接操作 `WorldStore`
+### 5.5 特殊实体恢复仍然沿用旧入口
 
-修订后需要一个统一仓储层，例如：
-- `src/world/runtime-entities/RuntimeEntityRepository.js`
+本阶段不改恢复总线：
 
-它负责：
-- `loadChunkRuntimeEntities(cx, cz)`
-- `upsertEntity(ownerCx, ownerCz, entityRecord)`
-- `removeEntity(ownerCx, ownerCz, type, id)`
-- `moveEntity(fromCx, fromCz, toCx, toCz, entityRecord)`
-- `migrateLegacyEntitiesIfNeeded(cx, cz, legacySnapshot)`
+1. `Chunk.finalizeNonDeferredPhase()`
+2. `restoreNestsForChunk()`
+3. `restoreTurretsForChunk()`
+4. `restoreMinecartsForChunk()`
 
-### 7.2 仓储层必须提供“按 chunk 串行化更新”
+真正要修的是：
 
-必须新增类似接口：
+1. 它们读到的结构方块必须还在
+2. 它们读到的 `cache.entities` 必须没丢
 
-```js
-await runtimeEntityRepository.updateChunkRuntimeEntities(cx, cz, updater)
-```
+### 5.6 结构方块与特殊形状的边界
 
-要求：
-- 同一 chunk 的更新在仓储层串行化
-- `updater` 以最新 `runtimeEntities` 为输入
-- 返回新的 `runtimeEntities`
-- 避免 Manager 自己读改写造成覆盖
+这次必须明确：
 
-### 7.3 必须新增活动实例生命周期 API
+1. 炮塔底座、柱子、巢穴结构、铁轨，都是 **普通方块侧数据**
+2. 它们应该继续走 `blockData`
+3. consolidation、AO、面剔除也继续只围绕 `blockData`
+4. 不要为这些结构额外再造一套“特殊形状权威”
 
-三个 manager 都要补齐：
-- `activateChunkEntities(cx, cz, records)`
-- `deactivateChunkEntities(cx, cz, options)`
-- `serializeActiveEntity(instance)`
-- `deserializeEntity(record)`
+也就是说：
 
-当前 `restoreXxxForChunk()` 只覆盖了“恢复”，没有对称的“卸载停用”语义，不够。
+1. 特殊实体的“特殊”主要体现在 **逻辑实例**
+2. 它们的结构主体依旧是块世界的一部分
 
 ---
 
-## 8. 旧机制兼容与迁移策略
+## 6. 第一阶段需要补齐的数据契约
 
-### 8.1 为什么不能直接删掉旧 `cache.entities`
+虽然本阶段不做正式入库，但 runtime snapshot 仍然应该增强，避免后续再次返工。
 
-因为当前项目还存在 `Chunk.gen()` / `assembleEntityPhase()` 这条旧快照路径。只动 runtime-streaming 路径会导致：
-- 新生成 chunk 与纯加载 chunk 行为不一致
-- 旧存档、旧会话缓存无法被一次性迁移
+### 6.1 `turret`
 
-### 8.2 兼容原则
+建议把快照从：
 
-第一阶段采取“双读单写”兼容：
-- **写入**：只写 `worldStore.runtimeEntities`
-- **读取**：优先读 `worldStore.runtimeEntities`，若为空，再读旧 `snapshot.entities` / `cache.entities` 做一次迁移
+1. `position`
+2. `rotation`
 
-### 8.3 迁移落点
+增强为：
 
-迁移动作必须集中在一个位置，不能散落在三个 manager 里。
+1. `id`
+2. `position`
+3. `rotation`
 
-推荐：
-- 在 `RuntimeEntityRepository.migrateLegacyEntitiesIfNeeded()` 内完成
-- 完成后回写 `worldStore`
-- 再把旧 `cache.entities` 标记为已迁移或清空对应字段
+本阶段不强制保存 pitch，因为当前炮塔默认会重新瞄准；但 `id` 最好补上，后续调试和去重都会更稳。
 
----
+### 6.2 `zombieNest`
+
+建议把快照从：
+
+1. `position`
+2. `criticalBlock`
+
+增强为：
+
+1. `id`
+2. `position`
+3. `criticalBlock`
+4. `lastSpawnTime`
 
-## 9. WorldRuntime / WorldStore 协同规则
+否则玩家可以靠卸载/加载刷新刷怪节奏。
 
-### 9.1 `putChunkRecord` 必须改成字段级合并语义
+### 6.3 `minecart`
 
-旧的全对象覆盖语义不再可接受。必须支持：
-- `blockData` 只更新 `blockData`
-- `runtimeEntities` 只更新 `runtimeEntities`
-- 两者互不覆盖
+矿车当前快照已经最接近可用状态，但仍要确认：
+
+1. `id`
+2. `position`
+3. `orientation`
+4. `movementState`
+5. `linkedMinecartIds`
+6. `chunkKey`
+
+是否都能稳定 round-trip。
+
+---
 
-### 9.2 `flushChunk` 只负责块工作集，不负责拼装实体状态
+## 7. 为什么这次不建议直接上 `RuntimeEntityRepository`
 
-`WorldRuntime.flushChunk()` 的职责应收敛为：
-- 把当前 chunk 的 `blockData / staticEntities / runtimeSeedData` 写回
-- 不直接拼接特殊实体运行时数据
+不是说这个方向永远不对，而是它不适合作为当前修复的第一步。
 
-特殊实体状态由各自 manager 在以下时机独立更新：
-- 创建
-- 销毁
-- 跨 chunk 移动
-- 卸载前停用
+当前最短闭环是：
 
-### 9.3 chunk 卸载前的顺序
+1. 先修 `blockData` 卸载竞态
+2. 让 `cache.blocks + cache.entities` 在 `worldStore` 路径上重新闭环
+3. 验证炮塔、巢穴、铁轨、矿车在 runtime 会话内的卸载/重载全部正常
+4. 再评估特殊实体是否真的要入 `worldStore`
 
-必须固定顺序：
-1. `minecartManager.deactivateChunkEntities()` 先停止并落盘
-2. 其他特殊实体 manager 执行停用
-3. `worldRuntime.flushBeforeUnload()` 写回方块工作集
-4. `chunk.dispose()`
+如果跳过这一步，继续推大仓储抽象，会有三个问题：
 
-如果顺序反过来，就会再次出现“chunk 已经删了，flush 才开始读”的问题。
+1. 先修错层，定位更乱
+2. 把当前还能工作的旧机制一起推翻
+3. 测试面会瞬间放大
 
 ---
 
-## 10. 本次设计的推荐边界
+## 8. 本阶段完成标准
 
-### 10.1 本次必须完成
+### 必须成立
 
-1. 三类实体统一迁移到 `worldStore.runtimeEntities`
-2. 新增统一仓储层，避免 Manager 直接改 `WorldStore`
-3. 明确激活/停用语义，补齐 chunk 卸载回收与恢复
-4. 打通 runtime-streaming 与旧 snapshot 路径的兼容桥
-5. 明确 `blockData` 与 `runtimeEntities` 的职责边界
+1. 放置铁轨后，玩家跑远卸载 chunk，再回来，铁轨仍正确渲染
+2. 放置炮塔后，玩家跑远再回来，底座、柱子、炮塔头部都存在，炮塔仍能射击
+3. 放置丧尸巢穴后，玩家跑远再回来，结构仍存在，巢穴仍能继续刷怪
+4. 放置矿车后，玩家跑远再回来，矿车仍在正确位置
+5. 以上能力在 **不依赖重新启动游戏** 的单次 runtime 会话里成立
 
-### 10.2 本次不做
+### 本阶段不要求
 
-1. 把所有特殊实体都抽成通用 ECS
-2. 完全删除 `persistenceService.cache`
-3. 重写 `Chunk.gen()` 整条旧路径
-4. 把敌人、炮弹、掉落物也一起迁移到 runtimeEntities
+1. 关闭页面后特殊实体从 IndexedDB 恢复
+2. `worldStore` 持有特殊实体正式权威数据
+3. 特殊实体 chunk 级生命周期彻底重写
 
 ---
 
-## 11. 设计结论
+## 9. 第二阶段再做什么
 
-修订后的核心原则只有三条：
+等第一阶段跑稳以后，再单独开第二阶段设计：
 
-1. **`IndexedDB / worldStore` 是唯一权威源，Manager 活动实例只是投影。**
-2. **特殊实体不能再按一种类型统一对待，必须区分“纯逻辑、纯渲染、混合渲染”。**
-3. **这个改造不是只改保存位置，而是要补齐 lifecycle、merge 语义、兼容桥和卸载恢复机制。**
+1. 是否把 `cache.entities` 正式搬入 `worldStore`
+2. 是否需要 `RuntimeEntityRepository`
+3. 是否要为炮塔/巢穴改成显式 chunk 激活/停用
+4. 保存/读档与 IndexedDB 的统一协议
 
-如果不先补这四个基础能力，继续按上一次的计划去 patch，只会反复掉进“局部看起来对，跑起来还是错”的循环。
+在那之前，不应该再把当前 bug 修复目标继续扩张。

-**Goal:** 将 `turret`、`minecart`、`zombieNest` 从旧的 `persistenceService.cache.entities` 机制迁移到 `worldStore / IndexedDB` 权威模型，并补齐 chunk 卸载/恢复、渲染恢复、旧路径兼容、并发写入保护。
+**Goal:** 修复炮塔、丧尸巢穴、铁轨和矿车在单次 runtime 会话内的 chunk 卸载/重载正确性，先恢复旧机制在新 `worldStore` 架构下的可用性。
 
-**Architecture:** 不再让各 Manager 直接 `getChunkRecord -> 改对象 -> putChunkRecord`。新增统一的 `RuntimeEntityRepository` 作为 `runtimeEntities` 的唯一写入入口；`blockData` 与 `runtimeEntities` 分层管理；活动实例采用“按 chunk 激活/停用”的显式生命周期。
+**Architecture:** 本阶段不把特殊实体正式迁入 `worldStore / IndexedDB`。继续使用 `persistenceService.cache.entities` 作为特殊实体 runtime 权威快照，并把 `cache.blocks` 重新接回 `worldStore` 读取路径，形成“活动 chunk.blockData + 会话级 cache overlay + worldStore 异步镜像”的三层闭环。

 ## 先决原则
 
-### 必须遵守
-- `worldStore / IndexedDB` 是权威源，`persistenceService.cache` 只是兼容桥和工作缓存。
-- 任何新逻辑不得只写旧 `cache.entities`。
-- 不能直接在三个 Manager 内部分散实现 chunkRecord 读改写。
-- 必须同时验证两条装载链路：
-  - `WorldRuntime.ensureChunkData()` -> `Chunk.loadFromRecord()`
-  - `Chunk.gen()` / `assembleEntityPhase()` 的旧快照路径
+### 本阶段必须坚持
 
-### 本计划不接受的“伪完成”
-- 仅修改 `Chunk.loadFromRecord()`
-- 仅给 `WorldStore.getChunkRecord()` 加字段
-- 只让实体“刷新页面能恢复”，但 chunk 卸载/恢复仍异常
-- 只验证 minecart，不验证 turret / zombieNest
+1. 不新建 `worldStore.runtimeEntities`
+2. 不引入 `RuntimeEntityRepository`
+3. 不重写炮塔/丧尸巢穴为“按 chunk 激活/停用”的新生命周期
+4. 先修通 runtime 会话内存期正确性，再谈 IndexedDB 权威化
+
+### 本阶段真正的修复目标
+
+1. 结构方块不能在 chunk 卸载时丢失
+2. `persistenceService.cache.entities` 不能在新读取链路里失联
+3. chunk 回来后要能重新看到铁轨、炮塔结构、巢穴结构
+4. 炮塔和巢穴不能因为结构方块丢失而误自毁
+
+### 本计划明确不接受的“伪完成”
+
+1. 只修 `turretManager` / `zombieNestManager` 恢复入口
+2. 只给 `worldStore` 加 `runtimeEntities`
+3. 不修卸载写回竞态
+4. 手工验证只看矿车，不看铁轨/炮塔/巢穴结构

+- Modify: `src/services/PersistenceService.js`
 
-- [ ] **Step 1: 新建 `RuntimeEntityRepository` 骨架**
+- [ ] **Step 1: 增加“确保 chunk 快照存在”的公共方法**
 
-提供最少接口：
+建议新增：
 
 ```js
-loadChunkRuntimeEntities(cx, cz)
-updateChunkRuntimeEntities(cx, cz, updater)
-upsertEntity(cx, cz, type, entityRecord)
-removeEntity(cx, cz, type, entityId)

-migrateLegacyEntitiesIfNeeded(cx, cz, legacyEntities)
+ensureChunkSnapshot(chunkKey, seed = {})
 ```
 
-- [ ] **Step 2: 给仓储层实现按 chunk 串行化更新**
+职责：
 
-要求：
-- 内部维护 `Map<chunkKey, Promise>` 或等价队列
-- 同一 chunk 的 `updateChunkRuntimeEntities()` 串行执行
-- `updater` 总是基于最新值生成新值
+1. 保证 `cache.get(chunkKey)` 一定有 `{ blocks, entities }`
+2. 不再让调用方自己散落地拼空对象
 
-- [ ] **Step 3: 统一 `runtimeEntities` 的默认结构**
+- [ ] **Step 2: 增加“用外部记录填充/合并 blocks”的公共方法**
 
-保证仓储层输出始终是：
+建议新增：
 
 ```js
-{ version: 1, byType: { turrets: [], minecarts: [], zombieNests: [] } }
+hydrateChunkBlocks(chunkKey, blockData)
+replaceChunkBlocks(chunkKey, blockData)
+snapshotChunkBlocks(chunkKey, blockData)
 ```
 
-避免调用方自己判空和拼结构。

-- `putChunkRecord()` 明确为字段级合并，而不是全对象覆盖
-- 对 `runtimeEntities` 支持“缺省保留、显式覆盖”语义
+当前行为是：cache 不存在就直接 return。  
+这会让 runtime-streaming 下很多块修改根本进不了会话快照。

+修正要求：
 
-确认 `flushChunk()` 只写：
-- `blockData`
-- `staticEntities`

+1. cache 缺失时自动创建快照
+2. 后续方块增量必须写入 `cache.blocks`

-- [ ] **Step 1: 修正 `Chunk.loadFromRecord()`**
 
-从 `chunkRecord.runtimeEntities` 读取，并填充 `pendingRuntimeEntities`。
+- [ ] **Step 1: 把 `worldStore` 读到的 `blockData` 注入 session cache**
 
 要求：
-- 不再依赖旧 `cache.entities` 作为主来源
-- 兼容 `runtimeEntities.version` 与 `byType` 结构
 
-- [ ] **Step 2: 修正 `assembleEntityPhase()` 的旧快照逻辑**
+1. `loadFromRecord()` 一进入就确保 `persistenceService.cache[chunkKey]` 存在
+2. 若 cache 还没有 `blocks`，用 `chunkRecord.blockData` 种进去
+
+- [ ] **Step 2: 明确 block 读取优先级**
+
+本阶段建议优先级：
+
+1. `cache.blocks` 有值时，用 `cache.blocks`
+2. 否则用 `chunkRecord.blockData`
 
-这里不能简单删除旧逻辑；要改成兼容桥：
-- 若 `pendingRuntimeEntities` 已有 `worldStore` 数据，则直接使用
-- 若 `worldStore` 为空但旧 `snapshot.entities` / `cache.entities` 有值，则走迁移流程
+原因：
+
+1. runtime 会话内用户最新修改可能只存在于 session overlay
+2. 不能要求每次重新进可见范围都依赖 `worldStore` 已成功 flush
+
+- [ ] **Step 3: 保留 runtime entities 仅从 `cache.entities` 恢复**
 
-- [ ] **Step 3: 提炼统一的 runtime entity hydration 逻辑**
+要求：
 
-避免 `loadFromRecord()` 和 `assembleEntityPhase()` 各自拷一套解析代码。
+1. `pendingRuntimeEntities` 继续从 `cache.entities` 提取
+2. 不要引入 `chunkRecord.runtimeEntities`
+3. 不要在这里尝试 IndexedDB 特殊实体迁移
 
-推荐：
-- 提炼 `extractPendingRuntimeEntities(recordOrLegacySnapshot)`
-- 或创建 `RuntimeEntityLoadBridge`
+- [ ] **Step 4: 让 finalize 恢复逻辑保持不变**
 
-- [ ] **Step 4: 保留旧路径的最小兼容性，不让旧 cache 反向覆盖新权威值**
+要求：
 
-必须保证：
-- 旧 `cache.entities` 只能在 `worldStore.runtimeEntities` 缺失时参与迁移
-- 不能再无条件 merge 到新权威值上面
+1. `finalizeNonDeferredPhase()` 仍然调用三个 manager 的现有 `restoreXxxForChunk()`
+2. 本任务只修数据输入，不改恢复总线

-- 激活时只创建活动实例，不再重复写回持久层

-要求：

-- `zombieNest`：销毁逻辑实例，但不删除持久记录
-- `minecart`：先停止运动并保存，再销毁实例
+二选一即可，但必须明确：

+1. 要么卸载路径里 `await flushBeforeUnload()`
+2. 要么 `flushChunk()` 改成允许传入已抓取的快照，不再回头从 `world.chunks.get(key)` 取活动 chunk
 
-固定顺序：
-1. 各 manager 先停用 owner chunk 内活动实例
-2. `worldRuntime.flushBeforeUnload()` 落地方块工作集
-3. `chunk.dispose()`
+推荐第二种。因为它更不依赖调用时序。

Subject: [PATCH 26/66] fix(runtime-entities): repair session persistence for
 special entities on chunk unload/reload

This commit fixes the root cause where blockData was lost during chunk
unloading due to an async flush race condition, and restores the
session-level cache overlay mechanism to work correctly with the new
WorldStore architecture.

Changes:

- PersistenceService:
  - Auto-create session snapshots when cache is missing in recordChangeForChunk
  - Add ensureChunkSnapshot, snapshotChunkBlocks, hydrateChunkBlocks,
    replaceChunkBlocks for unified session overlay management
  - Fix saveChunkData to merge data without overwriting existing entities/blocks

- Chunk.loadFromRecord:
  - Ensure persistenceService cache snapshot exists on entry
  - Use cache.blocks as authority over chunkRecord.blockData (overlay semantics)
  - Keep runtime entities recovery from cache.entities unchanged

- World (chunk unload):
  - Fix unload order: snapshot blocks -> stop minecarts -> async flush ->
    dispose -> delete from active set
  - snapshotChunkBlocks is now synchronous and happens before any async work

- WorldRuntime:
  - flushChunk/flushBeforeUnload now accept an optional blockDataSnapshot
    so they no longer depend on the active chunk still being present

- TurretManager:
  - Add id to turret snapshots
  - Use id for deduplication, with position as compatibility fallback
  - restoreTurretsForChunk reuses snapshot id via restoredId option

- ZombieNestManager:
  - Add id and lastSpawnTime to nest snapshots
  - Use id for deduplication
  - restoreNestsForChunk reuses snapshot id and lastSpawnTime

- MinecartManager:
  - Use id for deduplication in saveMinecartToSnapshot
  - restoreMinecartsForChunk skips existing ids to avoid duplicates

- Tests:
  - Add test-runtime-session-persistence.js covering unload/reload scenarios
  - Update test-persistence.js to match auto-snapshot behavior

- Docs:
  - Mark Phase 1 as complete in design and plan documents

+# Runtime Entities Unified Persistence — Phase 2 Design Spec
+
+**Date:** 2026-04-28
+**Author:** Claude Code
+**Status:** Draft
+**Predecessors:** [Runtime Entities Persistence Design (Phase 1)](../../plans/2026-04-28-runtime-entities-persistence-design.md), [WorldStore Runtime Streaming Design](./2026-04-26-worldstore-runtime-streaming-design.md)
+
+---
+
+## 1. Goal
+
+统一运行时特殊实体（炮塔、丧尸巢穴、矿车）的持久化路径，将其从 `persistenceService.cache.entities`（内存 + `world_deltas` 表）迁入 `worldStore` 的 `ChunkRecord.runtimeEntities`（`world_regions` 表），实现跨页面重启的持久化恢复。
+
+## 2. Scope
+
+### In Scope
+- 扩展 `ChunkRecord` 格式，新增 `runtimeEntities` 字段
+- 修改 `WorldRuntime.flushBeforeUnload` 写入 entities
+- 修改 `Chunk.loadFromRecord` 读取 runtimeEntities
+- 实现渐进式迁移（旧存档读取时自动从 `world_deltas` 迁移到 `world_regions`）
+- 修改 `Game.collectSnapshot` 从 `worldStore` 读取（手动存档路径统一）
+- 修改 `ManualSaveWorker` 兼容新格式
+
+### Out of Scope
+- `RuntimeEntityRepository` 抽象层（独立职责拆分）
+- Chunk 级 `activate/deactivate` 生命周期钩子
+- `world_deltas` 表的彻底删除（保留作为降级保护）
+- Worker 端 entity 处理（entities 始终在主线程收集和写入）
+- Region 级 entity 聚合（保持 chunk 级粒度）
+
+## 3. Architecture
+
+### 3.1 ChunkRecord 格式扩展
+
+```js
+// src/world/WorldStore.js — ChunkRecord 格式
+{
+  blockData: { '12345': 1, ... },              // 编码的方块数据
+  staticEntities: [{ type: 'tree', ... }],      // 地形生成实体
+  runtimeSeedData: { structureCenters: [...] }, // 结构种子数据
+  runtimeEntities: {                             // 【新增】运行时实体快照
+    turrets: [{ id, position: {x,y,z}, rotation }],
+    zombieNests: [{ id, position: {x,y,z}, criticalBlock: {x,y,z,type}, lastSpawnTime }],
+    minecarts: [{ id, position: {x,y,z}, movementState: 'IDLE'|'MOVING', ... }]
+  }
+}
+```
+
+`runtimeEntities` 是可选字段。不含此字段的旧存档在读取时触发渐进式迁移。
+
+### 3.2 数据流
+
+#### 写入路径（Chunk Unload）
+
+```
+World.update() — chunk unload 路径:
+1. persistence.snapshotChunkBlocks(key, chunk.blockData)    // 同步
+2. minecartManager.stopMinecartsForChunk(cx, cz)            // 停止移动矿车
+3. worldRuntime.flushBeforeUnload(cx, cz, blockData, entities)  // 新增 entities 参数
+   → WorldRuntime._collectEntitiesForChunk(cx, cz):
+     - turretManager.getEntitiesForChunk(cx, cz)
+     - zombieNestManager.getEntitiesForChunk(cx, cz)
+     - minecartManager.getEntitiesForChunk(cx, cz)
+   → putChunkRecord(cx, cz, { ..., runtimeEntities: entities })
+   → WorldStore.saveRegionRecord(rx, rz, region)            // IndexedDB
+4. chunk.dispose()
+5. this.chunks.delete(key)
+```
+
+#### 读取路径（Chunk Load）
+
+```
+Chunk.loadFromRecord(chunkRecord):
+1. persistence.ensureChunkSnapshot(chunkKey)                // 确保 cache 存在
+2. persistence.hydrateChunkBlocks(chunkRecord.blockData)    // cache.blocks 优先
+3. _injectBlockData(effectiveBlockData)
+4. _injectStaticEntities(chunkRecord.staticEntities)
+5. structureCenters = chunkRecord.runtimeSeedData
+6. 读取 runtimeEntities:
+   if chunkRecord.runtimeEntities:
+     → 使用 chunkRecord.runtimeEntities（新格式）
+   else:
+     → 从 persistence.cache.get(chunkKey)?.entities 读取（旧格式）
+     → this._needsEntityMigration = true
+7. _buildMeshFromExistingBlockData()
+8. finalizeNonDeferredPhase()
+   → restoreNestsForChunk() / restoreTurretsForChunk() / restoreMinecartsForChunk()
+```
+
+#### 渐进式迁移路径
+
+```
+Chunk.finalizeNonDeferredPhase() — 若 _needsEntityMigration 为 true:
+1. 从 world_deltas 读取 legacyData = persistence.workerGetChunkData(cx, cz)
+2. if legacyData?.entities:
+   → chunkRecord.runtimeEntities = legacyData.entities
+   → worldStore.putChunkRecord(cx, cz, chunkRecord)          // 回填
+   → log: "migrated runtime entities for chunkKey"
+3. else:
+   → chunkRecord.runtimeEntities = { turrets: [], zombieNests: [], minecarts: [] }
+```
+
+### 3.3 手动存档路径统一
+
+#### collectSnapshot（Game.js）
+
+```js
+// before: 从 persistenceService.cache 读取
+// after: 从 worldStore 读取已加载 chunk 的完整数据
+collectSnapshot() {
+  const worldDeltas = [];
+  for (const [key, chunk] of this.world.chunks.entries()) {
+    const record = this.world.worldStore.getChunkRecord(chunk.cx, chunk.cz);
+    worldDeltas.push({
+      key,
+      blocks: record.blockData,
+      entities: record.runtimeEntities || {}
+    });
+  }
+  return { player: {...}, worldDeltas, seed: this.seed, settings: {...} };
+}
+```
+
+#### loadSnapshot（ManualSaveWorker）
+
+`ManualSaveWorker` 的 `load` 路径兼容两种格式的 `worldDeltas`：
+- 新格式：`{ key, blocks, entities }` 其中 `entities` 包含 `turrets/zombieNests/minecarts`
+- 旧格式：`{ key, blocks, entities }` 结构相同但来自 `world_deltas` 表
+
+两者格式一致，无需额外兼容代码。
+
+## 4. Detailed Changes
+
+### 4.1 WorldRuntime.js
+
+#### `flushBeforeUnload(cx, cz, blockDataSnapshot, entitiesSnapshot)`
+
+- 新增第四个参数 `entitiesSnapshot`（可选）
+- 若无传入，调用 `_collectEntitiesForChunk(cx, cz)` 收集
+- 构建包含 `runtimeEntities` 的完整 `ChunkRecord`
+
+#### `_collectEntitiesForChunk(cx, cz)`
+
+- 新方法，从三个 manager 收集实体：
+  ```js
+  {
+    turrets: this.game.turretManager.getEntitiesForChunk(cx, cz),
+    zombieNests: this.game.zombieNestManager.getEntitiesForChunk(cx, cz),
+    minecarts: this.game.minecartManager.getEntitiesForChunk(cx, cz)
+  }
+  ```
+
+#### `_ensureChunkEntitiesMigrated(cx, cz, chunkRecord)`
+
+- 新方法，检查 `chunkRecord.runtimeEntities` 是否存在
+- 若不存在，从 `world_deltas` 读取 entities 并回填
+- 回填后调用 `putChunkRecord` 持久化
+
+### 4.2 World.js
+
+#### `World.update()` — chunk unload 路径
+
+```js
+// before
+this.worldRuntime.flushBeforeUnload(cx, cz, chunk.blockData);
+
+// after
+const entities = this._collectRuntimeEntitiesForChunk(chunk);
+this.worldRuntime.flushBeforeUnload(cx, cz, chunk.blockData, entities);
+```
+
+#### `_collectRuntimeEntitiesForChunk(chunk)`
+
+- 新方法，在 `World.js` 中收集当前 chunk 的 runtime entities
+- 通过 `turretManager.getEntitiesForChunk()` / `zombieNestManager.getEntitiesForChunk()` / `minecartManager.getEntitiesForChunk()` 获取
+- 需要在三个 manager 中新增 `getEntitiesForChunk(cx, cz)` 方法
+
+### 4.3 Chunk.js
+
+#### `loadFromRecord(chunkRecord)`
+
+- 修改 runtime entities 读取逻辑，优先使用 `chunkRecord.runtimeEntities`
+- 若不存在，回退 `persistence.cache.get(chunkKey)?.entities`
+- 标记 `this._needsEntityMigration = true` 触发渐进迁移
+
+#### `finalizeNonDeferredPhase()`
+
+- 若 `_needsEntityMigration` 为 true，调用 `WorldRuntime._ensureChunkEntitiesMigrated()`
+- 迁移完成后清除标记
+
+### 4.4 Game.js
+
+#### `collectSnapshot()`
+
+- 改为从 `worldStore` 读取已加载 chunk 的完整数据
+- `worldDeltas` 中 `entities` 字段来自 `chunkRecord.runtimeEntities`
+
+#### `restoreSnapshot(saveData)`
+
+- 加载时 `worldDeltas` 包含 `{ key, blocks, entities }`
+- 注入时通过 `injectSaveData` 写入 `persistenceService.cache`
+- `Chunk.loadFromRecord` 从 `cache.entities` 读取并恢复实体
+
+### 4.5 PersistenceService.js
+
+- `cache.entities` 保留为临时层，渐进迁移后不再作为权威数据源
+- 保留所有 Phase 1 添加的方法（`ensureChunkSnapshot`, `snapshotChunkBlocks`, `hydrateChunkBlocks`, `replaceChunkBlocks`）
+- 新增 `workerGetChunkData(cx, cz)` 方法：向 PersistenceWorker 请求读取 `world_deltas` 表的数据（仅用于渐进迁移）
+
+### 4.6 PersistenceWorker.js
+
+- 新增 `getChunkData` action（已有，但此前仅用于 `saveChunkData` 配对）
+- 确保 `getChunkData` 返回包含 `{ blocks, entities }` 的完整记录
+
+### 4.7 ManualSaveWorker.js
+
+- `load` 路径中 `worldDeltas` 的格式不变（`{ key, blocks, entities }`）
+- `injectSaveData` 接收后写入 `persistenceService.cache`，兼容新格式
+
+### 4.8 Three Managers（TurretManager, ZombieNestManager, MinecartManager）
+
+每个 manager 新增 `getEntitiesForChunk(cx, cz)` 方法：
+
+```js
+// TurretManager
+getEntitiesForChunk(cx, cz) {
+  const chunkKey = `${cx},${cz}`;
+  return this.turrets
+    .filter(t => {
+      const tcx = Math.floor(t.position.x / 16);
+      const tcz = Math.floor(t.position.z / 16);
+      return tcx === cx && tcz === cz;
+    })
+    .map(t => ({ id: t.id, position: t.position, rotation: t.rotation }));
+}
+
+// ZombieNestManager
+getEntitiesForChunk(cx, cz) {
+  const chunkKey = `${cx},${cz}`;
+  return this.nests
+    .filter(n => {
+      const ncx = Math.floor(n.position.x / 16);
+      const ncz = Math.floor(n.position.z / 16);
+      return ncx === cx && ncz === cz;
+    })
+    .map(n => ({ id: n.id, position: n.position, criticalBlock: n.criticalBlock, lastSpawnTime: n.lastSpawnTime }));
+}
+
+// MinecartManager
+getEntitiesForChunk(cx, cz) {
+  return this.minecarts
+    .filter(m => {
+      const mcx = Math.floor(m.position.x / 16);
+      const mcz = Math.floor(m.position.z / 16);
+      return mcx === cx && mcz === cz;
+    })
+    .map(m => m.toJSON());
+}
+```
+
+同时，三个 manager 的 `saveXxxToSnapshot` 方法继续保留，用于运行时实时更新 `cache.entities`（作为写入缓冲），但权威数据源切换为 `worldStore`。
+
+## 5. Backward Compatibility
+
+### 5.1 旧存档加载
+
+- `ChunkRecord.runtimeEntities` 不存在时，`Chunk.loadFromRecord` 回退 `cache.entities`
+- 触发 `_needsEntityMigration` 标记，从 `world_deltas` 提取并回填
+- 回填后旧 chunk 获得完整 `runtimeEntities`，后续加载不再触发迁移
+
+### 5.2 world_deltas 保留
+
+- 迁移后不删除 `world_deltas` 表中的数据
+- `world_deltas` 保留作为降级保护（若 `world_regions` 写入失败可回退）
+- 后续版本可考虑添加清理工具删除已迁移的旧数据
+
+### 5.3 手动存档兼容
+
+- 手动存档格式不变（`worldDeltas` 仍为 `{ key, blocks, entities }`）
+- 新存档：`entities` 来自 `worldStore.runtimeEntities`
+- 旧存档：`entities` 来自 `world_deltas`（格式相同）
+- 加载路径无需区分新旧格式
+
+## 6. Validation
+
+### 6.1 回归测试
+- 放置炮塔 → 跑远卸载 chunk → 返回确认底座/柱子/炮塔头都在且能开火
+- 放置丧尸巢穴 → 跑远卸载 → 返回确认结构还在且刷怪节奏不重置
+- 放置铁轨和矿车 → 跑远卸载 → 返回确认位置正确
+
+### 6.2 跨重启测试
+- 放置实体 → 关闭页面 → 重新打开 → 确认实体存在
+- 运动中的矿车 → 关闭页面 → 重新打开 → 确认矿车已停止在正确位置
+
+### 6.3 渐进迁移测试
+- 加载包含实体的旧存档（仅有 `world_deltas`）→ 读取包含实体的 chunk → 确认 `runtimeEntities` 已回填到 `world_regions`
+- 清除 `world_deltas` → 重新加载 → 确认实体仍可从 `world_regions` 恢复
+
+### 6.4 手动存档测试
+- 放置实体 → 手动存档 → 清除 `world_deltas` → 加载存档 → 确认实体正确恢复
+
+## 7. Risks
+
+| 风险 | 影响 | 缓解措施 |
+|------|------|----------|
+| `collectSnapshot` 只序列化已加载 chunk | 未探索区域不在存档中 | 用户提示"当前存档仅包含已探索区域" |
+| 三个 manager 全局持有实体引用 | 长时间运行可能积累内存 | 与一阶段行为一致，不引入新风险 |
+| 渐进迁移时 `world_deltas` 读取失败 | 实体丢失 | `world_deltas` 保留不删除，加载失败时创建空结构 |
+| `flushBeforeUnload` 写入 `world_regions` 时 region 较大 | IndexedDB 写入延迟 | 与现有 blockData 写入路径一致，无额外开销 |

+# Runtime Entities Unified Persistence — Phase 2 Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** 将运行时特殊实体（炮塔、丧尸巢穴、矿车）的持久化路径从 `persistenceService.cache.entities` + `world_deltas` 表统一迁入 `worldStore` 的 `ChunkRecord.runtimeEntities`（`world_regions` 表），实现跨页面重启的持久化恢复。
+
+**Architecture:** 扩展 ChunkRecord 格式新增 `runtimeEntities` 字段，修改 `flushBeforeUnload` 写入 entities，`loadFromRecord` 优先读取 runtimeEntities 并支持从 `world_deltas` 渐进迁移，`collectSnapshot` 改为从 worldStore 读取。
+
+**Tech Stack:** JavaScript (ES Modules), IndexedDB, Three.js v0.160.0
+

+
+### Task 1: 三个 Manager 新增 `getEntitiesForChunk` 方法
+
+**Files:**
+- Modify: `src/actors/turret/TurretManager.js`
+- Modify: `src/actors/zombie-nest/ZombieNestManager.js`
+- Modify: `src/actors/minecart/MinecartManager.js`
+
+每个 manager 新增一个方法，用于按 chunk 坐标收集该 chunk 内的所有实体快照数据。
+
+- [ ] **Step 1: TurretManager 添加 `getEntitiesForChunk`**
+
+在 `TurretManager.js` 中添加 `getEntitiesForChunk(cx, cz)` 方法。放在 `clearAll()` 方法之前（约 line 425 附近）。
+
+```js
+// src/actors/turret/TurretManager.js — 添加在 clearAll() 之前
+
+/**
+ * 收集指定 chunk 内的所有炮塔快照数据。
+ * @param {number} cx - chunk X 坐标
+ * @param {number} cz - chunk Z 坐标
+ * @returns {Array<{id: string, position: {x:number,y:number,z:number}, rotation: {yaw:number,pitch:number}}>}
+ */
+getEntitiesForChunk(cx, cz) {
+  const result = [];
+  for (const turret of this.turrets.values()) {
+    const tcx = Math.floor(turret.position.x / CHUNK_SIZE);
+    const tcz = Math.floor(turret.position.z / CHUNK_SIZE);
+    if (tcx === cx && tcz === cz) {
+      result.push(this.toTurretSnapshot(turret));
+    }
+  }
+  return result;
+}
+```
+
+需要确认 `CHUNK_SIZE` 常量在该文件中是否已导入。检查文件顶部 import 部分，如果没有，添加：
+
+```js
+import { CHUNK_SIZE } from '../../constants/GameConfig.js';
+```
+
+- [ ] **Step 2: ZombieNestManager 添加 `getEntitiesForChunk`**
+
+在 `ZombieNestManager.js` 中添加 `getEntitiesForChunk(cx, cz)` 方法。放在 `destroy()` 方法之前（约 line 316 附近）。
+
+```js
+// src/actors/zombie-nest/ZombieNestManager.js — 添加在 destroy() 之前
+
+/**
+ * 收集指定 chunk 内的所有丧尸巢穴快照数据。
+ * @param {number} cx - chunk X 坐标
+ * @param {number} cz - chunk Z 坐标
+ * @returns {Array<{id: string, position: {x:number,y:number,z:number}, criticalBlock: {x:number,y:number,z:number,type:number}, lastSpawnTime: number}>}
+ */
+getEntitiesForChunk(cx, cz) {
+  const result = [];
+  for (const nest of this.nests.values()) {
+    const ncx = Math.floor(nest.position.x / CHUNK_SIZE);
+    const ncz = Math.floor(nest.position.z / CHUNK_SIZE);
+    if (ncx === cx && ncz === cz) {
+      result.push(this.toNestSnapshot(nest));
+    }
+  }
+  return result;
+}
+```
+
+同样需要确认 `CHUNK_SIZE` 是否已导入。如没有，添加：
+
+```js
+import { CHUNK_SIZE } from '../../constants/GameConfig.js';
+```
+
+- [ ] **Step 3: MinecartManager 添加 `getEntitiesForChunk`**
+
+在 `MinecartManager.js` 中添加 `getEntitiesForChunk(cx, cz)` 方法。放在 `clearAll()` 方法之前（约 line 455 附近）。
+
+```js
+// src/actors/minecart/MinecartManager.js — 添加在 clearAll() 之前
+
+/**
+ * 收集指定 chunk 内的所有矿车快照数据。
+ * @param {number} cx - chunk X 坐标
+ * @param {number} cz - chunk Z 坐标
+ * @returns {Array<object>} — minecart.toJSON() 返回的完整序列化数据
+ */
+getEntitiesForChunk(cx, cz) {
+  const result = [];
+  for (const minecart of this.minecarts.values()) {
+    const mcx = Math.floor(minecart.position.x / CHUNK_SIZE);
+    const mcz = Math.floor(minecart.position.z / CHUNK_SIZE);
+    if (mcx === cx && mcz === cz) {
+      result.push(minecart.toJSON());
+    }
+  }
+  return result;
+}
+```
+
+同样需要确认 `CHUNK_SIZE` 是否已导入。如没有，添加：
+
+```js
+import { CHUNK_SIZE } from '../../constants/GameConfig.js';
+```
+
+- [ ] **Step 4: 验证 CHUNK_SIZE 导入**
+
+在三个文件中分别确认 `CHUNK_SIZE` 已正确导入。如果某个文件已有该导入（可能来自 `../../constants/GameConfig.js`），则不要重复添加。
+
+运行 lint 检查：
+
+```bash
+npm run lint
+```
+
+确认新增代码无 lint 错误。
+
+- [ ] **Step 5: Commit**
+
+```bash
+git add src/actors/turret/TurretManager.js src/actors/zombie-nest/ZombieNestManager.js src/actors/minecart/MinecartManager.js
+git commit -m "feat(runtime-entities): add getEntitiesForChunk to turret, zombie nest, and minecart managers
+
+Phase 2: unified persistence path — each manager can now serialize
+its entities scoped to a specific chunk for flushBeforeUnload."
+```
+
+---
+
+### Task 2: PersistenceService 新增 `workerGetChunkData` 方法
+
+**Files:**
+- Modify: `src/services/PersistenceService.js`
+
+为渐进式迁移提供从 `world_deltas` 表读取数据的能力。当前 `getChunkData` 方法已存在（line 79），但它是通过 Worker 调用的。新增一个明确用于渐进迁移的方法。
+
+- [ ] **Step 1: 添加 `workerGetChunkData` 方法**
+
+在 `PersistenceService.js` 的 `injectSaveData` 方法之前（约 line 270 附近）添加：
+
+```js
+// src/services/PersistenceService.js — 添加在 injectSaveData 之前
+
+/**
+ * 从 world_deltas 表读取指定 chunk 的完整数据（包含 blocks 和 entities）。
+ * 仅用于渐进式迁移：当 chunkRecord 不含 runtimeEntities 时，从此方法
+ * 获取旧格式的 entities 数据。
+ * @param {number} cx
+ * {number} cz
+ * @returns {Promise<{blocks?: object, entities?: {turrets?: Array, zombieNests?: Array, minecarts?: Array}}|null>}
+ */
+async workerGetChunkData(cx, cz) {
+  await this.initPromise;
+  const key = `${cx},${cz}`;
+  return this.rpc.getChunkData(key);
+}
+```
+
+- [ ] **Step 2: Commit**
+
+```bash
+git add src/services/PersistenceService.js
+git commit -m "feat(runtime-entities): add workerGetChunkData for progressive migration
+
+Phase 2: allows reading entities from world_deltas store during
+chunk load when chunkRecord.runtimeEntities is missing."
+```
+
+---
+
+### Task 3: WorldRuntime 修改 `flushBeforeUnload` 并添加 entity 收集方法
+
+**Files:**
+- Modify: `src/world/WorldRuntime.js`
+
+- [ ] **Step 1: 修改 `flushBeforeUnload` 方法签名**
+
+打开 `src/world/WorldRuntime.js`，找到 `flushBeforeUnload` 方法（约 line 262）。将方法从：
+
+```js
+// src/world/WorldRuntime.js — 修改前（约 line 262-277）
+async flushBeforeUnload(cx, cz, blockDataSnapshot) {
+  const key = this.worldStore.chunkKey(cx, cz);
+  const chunk = this._world?.chunks?.get(key);
+
+  const record = {
+    blockData: blockDataSnapshot || (chunk ? this._serializeBlockData(chunk.blockData) : {}),
+    staticEntities: chunk?.staticEntities ? [...chunk.staticEntities] : [],
+    runtimeSeedData: chunk?.structureCenters
+      ? { structureCenters: chunk.structureCenters }
+      : { structureCenters: [] }
+  };
+
+  await this.worldStore.putChunkRecord(cx, cz, record);
+  this.dirtyChunks.delete(key);
+}
+```
+
+改为：
+
+```js
+// src/world/WorldRuntime.js — 修改后
+async flushBeforeUnload(cx, cz, blockDataSnapshot, entitiesSnapshot) {
+  const key = this.worldStore.chunkKey(cx, cz);
+  const chunk = this._world?.chunks?.get(key);
+
+  const entities = entitiesSnapshot
+    || (this._game ? this._collectEntitiesForChunk(cx, cz) : null)
+    || { turrets: [], zombieNests: [], minecarts: [] };
+
+  const record = {
+    blockData: blockDataSnapshot || (chunk ? this._serializeBlockData(chunk.blockData) : {}),
+    staticEntities: chunk?.staticEntities ? [...chunk.staticEntities] : [],
+    runtimeSeedData: chunk?.structureCenters
+      ? { structureCenters: chunk.structureCenters }
+      : { structureCenters: [] },
+    runtimeEntities: entities
+  };
+
+  await this.worldStore.putChunkRecord(cx, cz, record);
+  this.dirtyChunks.delete(key);
+}
+```
+
+- [ ] **Step 2: 添加 `_collectEntitiesForChunk` 方法**
+
+在 `flushBeforeUnload` 方法之后（约 line 278 附近）添加：
+
+```js
+// src/world/WorldRuntime.js — 添加在 flushBeforeUnload 之后
+
+/**
+ * 从三个特殊实体 manager 收集指定 chunk 的实体快照。
+ */
+_collectEntitiesForChunk(cx, cz) {
+  const game = this._game;
+  if (!game) return { turrets: [], zombieNests: [], minecarts: [] };
+
+  return {
+    turrets: game.turretManager?.getEntitiesForChunk?.(cx, cz) || [],
+    zombieNests: game.zombieNestManager?.getEntitiesForChunk?.(cx, cz) || [],
+    minecarts: game.minecartManager?.getEntitiesForChunk?.(cx, cz) || []
+  };
+}
+```
+
+- [ ] **Step 3: 确认 `this._game` 赋值**
+
+检查 `WorldRuntime.js` 的构造函数（约 line 19-25），确认 `this._game` 是否已被赋值。如果没有，需要在构造函数中添加 `this._game = null;` 并在 `WorldRuntime.init(world, game)` 中设置 `this._game = game;`。
+
+查看构造函数的当前实现。如果构造函数接受 `game` 参数或通过 `init` 方法设置，则不需要额外修改。否则添加：
+
+```js
+// 在构造函数中添加
+this._game = null;
+
+// 在 init(world, game) 方法中设置
+this._game = game;
+```
+
+- [ ] **Step 4: 修改 `ensureChunkData` 调用渐进迁移**
+
+打开 `ensureChunkData` 方法（约 line 73-120）。在方法末尾、返回 `chunkRecord` 之前，添加渐进迁移检查：
+
+在 `ensureChunkData` 方法的末尾（返回 `chunkRecord` 之前），找到类似这样的代码：
+
+```js
+return { status: 'loaded', chunkRecord };
+```
+
+在其之前添加：
+
+```js
+// 渐进式迁移：如果 chunkRecord 不含 runtimeEntities，尝试从 world_deltas 迁移
+if (!chunkRecord.runtimeEntities) {
+  await this._ensureChunkEntitiesMigrated(cx, cz, chunkRecord);
+}
+```
+
+- [ ] **Step 5: 添加 `_ensureChunkEntitiesMigrated` 方法**
+
+在 `_collectEntitiesForChunk` 方法之后添加：
+
+```js
+// src/world/WorldRuntime.js — 添加在 _collectEntitiesForChunk 之后
+
+/**
+ * 渐进式迁移：当 chunkRecord 不含 runtimeEntities 时，从 world_deltas 表读取
+ * entities 并回填到 worldStore。
+ */
+async _ensureChunkEntitiesMigrated(cx, cz, chunkRecord) {
+  const persistence = getPersistenceService();
+  if (!persistence) {
+    chunkRecord.runtimeEntities = { turrets: [], zombieNests: [], minecarts: [] };
+    return;
+  }
+
+  const legacyData = await persistence.workerGetChunkData(cx, cz);
+
+  if (legacyData?.entities) {
+    chunkRecord.runtimeEntities = legacyData.entities;
+    // 回填到 worldStore
+    await this.worldStore.putChunkRecord(cx, cz, chunkRecord);
+    console.log(`[WorldRuntime] migrated runtime entities for chunk ${cx},${cz}`);
+  } else {
+    // world_deltas 中也没有，创建空结构
+    chunkRecord.runtimeEntities = { turrets: [], zombieNests: [], minecarts: [] };
+  }
+}
+```
+
+确认文件顶部有 `getPersistenceService` 的导入。如果没有，添加：
+
+```js
+import { getPersistenceService } from '../services/PersistenceService.js';
+```
+
+- [ ] **Step 6: Commit**
+
+```bash
+git add src/world/WorldRuntime.js
+git commit -m "feat(runtime-entities): WorldRuntime writes runtimeEntities on flush, supports progressive migration
+
+Phase 2: flushBeforeUnload now collects entities from three managers
+and includes runtimeEntities in ChunkRecord. ensureChunkData triggers
+progressive migration from world_deltas when runtimeEntities is missing."
+```
+
+---
+
+### Task 4: Chunk.js 修改 `loadFromRecord` 读取 runtimeEntities
+
+**Files:**
+- Modify: `src/world/Chunk.js`
+
+- [ ] **Step 1: 修改 `loadFromRecord` 中的 runtime entities 读取逻辑**
+
+打开 `src/world/Chunk.js`，找到 `loadFromRecord` 方法（约 line 282-355）。定位到读取 runtime entities 的部分（约 lines 327-345），将当前代码：
+
+```js
+// src/world/Chunk.js — 修改前（约 lines 327-345）
+const persistence = getPersistenceService();
+const cacheEntry = persistence?.cache?.get(chunkKey);
+const entities = cacheEntry?.entities || {};
+
+this.pendingRuntimeEntities = {
+  zombieNests: entities.zombieNests || [],
+  turrets: entities.turrets || [],
+  minecarts: entities.minecarts || []
+};
+```
+
+改为：
+
+```js
+// src/world/Chunk.js — 修改后
+this.pendingRuntimeEntities = {
+  zombieNests: [],
+  turrets: [],
+  minecarts: []
+};
+
+this._needsEntityMigration = false;
+
+if (chunkRecord.runtimeEntities) {
+  // 新格式：直接从 chunkRecord 读取
+  this.pendingRuntimeEntities = {
+    zombieNests: chunkRecord.runtimeEntities.zombieNests || [],
+    turrets: chunkRecord.runtimeEntities.turrets || [],
+    minecarts: chunkRecord.runtimeEntities.minecarts || []
+  };
+} else {
+  // 旧格式兼容：从 cache.entities 读取，标记需要渐进迁移
+  const persistence = getPersistenceService();
+  const cacheEntry = persistence?.cache?.get(chunkKey);
+  const entities = cacheEntry?.entities || {};
+  this.pendingRuntimeEntities = {
+    zombieNests: entities.zombieNests || [],
+    turrets: entities.turrets || [],
+    minecarts: entities.minecarts || []
+  };
+  this._needsEntityMigration = true;
+}
+```
+
+- [ ] **Step 2: 修改 `finalizeNonDeferredPhase` 触发渐进迁移**
+
+打开 `finalizeNonDeferredPhase` 方法（约 line 1820-1855）。在方法开头、任何实体恢复逻辑之前（约 line 1825 附近），添加：
+
+```js
+// src/world/Chunk.js — 在 finalizeNonDeferredPhase 开头添加
+if (this._needsEntityMigration) {
+  const worldRuntime = this.world?.worldRuntime;
+  if (worldRuntime) {
+    const chunkRecord = {
+      blockData: {},
+      staticEntities: [],
+      runtimeSeedData: { structureCenters: [] },
+      runtimeEntities: null
+    };
+    await worldRuntime._ensureChunkEntitiesMigrated(this.cx, this.cz, chunkRecord);
+    if (chunkRecord.runtimeEntities) {
+      this.pendingRuntimeEntities = {
+        zombieNests: chunkRecord.runtimeEntities.zombieNests || [],
+        turrets: chunkRecord.runtimeEntities.turrets || [],
+        minecarts: chunkRecord.runtimeEntities.minecarts || []
+      };
+    }
+  }
+  this._needsEntityMigration = false;
+}
+```
+
+注意：`finalizeNonDeferredPhase` 当前可能是同步方法。由于渐进迁移需要 async 操作，需要将该方法改为 `async`。修改方法签名：
+
+```js
+// 修改前
+finalizeNonDeferredPhase() {
+// 修改后
+async finalizeNonDeferredPhase() {
+```
+
+同时需要检查所有调用 `finalizeNonDeferredPhase` 的地方，确保它们 `await` 该方法。主要调用点在 `loadFromRecord` 末尾（约 line 354），将：
+
+```js
+this.finalizeNonDeferredPhase();
+```
+
+改为：
+
+```js
+await this.finalizeNonDeferredPhase();
+```
+
+- [ ] **Step 3: 运行 lint 检查**
+
+```bash
+npm run lint
+```
+
+确认无新增 lint 错误。
+
+- [ ] **Step 4: Commit**
+
+```bash
+git add src/world/Chunk.js
+git commit -m "feat(runtime-entities): Chunk.loadFromRecord reads runtimeEntities with progressive migration
+
+Phase 2: prefers chunkRecord.runtimeEntities (new format), falls back
+to cache.entities (old format) and triggers migration. finalizeNonDeferredPhase
+is now async to support the migration step."
+```
+
+---
+
+### Task 5: World.js 修改 chunk unload 路径传入 entities
+
+**Files:**
+- Modify: `src/world/World.js`
+
+- [ ] **Step 1: 修改 `World.update()` 中的 chunk unload 路径**
+
+打开 `src/world/World.js`，找到 chunk unload 部分（约 lines 801-835）。定位到 `flushBeforeUnload` 调用处（约 line 813-817），将：
+
+```js
+// src/world/World.js — 修改前
+this.worldRuntime.flushBeforeUnload(cx, cz, chunk.blockData);
+```
+
+改为：
+
+```js
+// src/world/World.js — 修改后
+const entities = this._collectRuntimeEntitiesForChunk(chunk);
+this.worldRuntime.flushBeforeUnload(cx, cz, chunk.blockData, entities);
+```
+
+- [ ] **Step 2: 添加 `_collectRuntimeEntitiesForChunk` 方法**
+
+在 `World.js` 中合适的位置（约 line 840 附近，在 `update` 方法之后）添加：
+
+```js
+// src/world/World.js — 添加在 update 方法之后
+
+/**
+ * 收集指定 chunk 的 runtime entities 快照，用于 chunk unload 时持久化。
+ */
+_collectRuntimeEntitiesForChunk(chunk) {
+  return {
+    turrets: this.turretManager?.getEntitiesForChunk?.(chunk.cx, chunk.cz) || [],
+    zombieNests: this.zombieNestManager?.getEntitiesForChunk?.(chunk.cx, chunk.cz) || [],
+    minecarts: this.minecartManager?.getEntitiesForChunk?.(chunk.cx, chunk.cz) || []
+  };
+}
+```
+
+- [ ] **Step 3: 运行 lint 检查**
+
+```bash
+npm run lint
+```
+
+- [ ] **Step 4: Commit**
+
+```bash
+git add src/world/World.js
+git commit -m "feat(runtime-entities): World.update collects and passes entities on chunk unload
+
+Phase 2: chunk unload path now includes runtime entities snapshot
+in flushBeforeUnload, ensuring they are written to worldStore."
+```
+
+---
+
+### Task 6: Game.js 修改 `collectSnapshot` 从 worldStore 读取
+
+**Files:**
+- Modify: `src/core/Game.js`
+
+- [ ] **Step 1: 修改 `collectSnapshot` 方法**
+
+打开 `src/core/Game.js`，找到 `collectSnapshot` 方法（约 lines 583-617）。将当前从 `persistenceService.cache` 读取的逻辑：
+
+```js
+// src/core/Game.js — 修改前（约 lines 583-617）
+collectSnapshot() {
+  const playerSnapshot = {
+    x: this.player.position.x,
+    y: this.player.position.y,
+    z: this.player.position.z,
+    pitch: this.player.pitch,
+    yaw: this.player.yaw
+  };
+
+  const worldDeltas = [];
+  for (const [key, data] of persistenceService.cache.entries()) {
+    if (!data) continue;
+    worldDeltas.push({ key, ...data });
+  }
+
+  return {
+    player: playerSnapshot,
+    worldDeltas,
+    seed: this.seed,
+    settings: { ...this.settings }
+  };
+}
+```
+
+改为：
+
+```js
+// src/core/Game.js — 修改后
+collectSnapshot() {
+  const playerSnapshot = {
+    x: this.player.position.x,
+    y: this.player.position.y,
+    z: this.player.position.z,
+    pitch: this.player.pitch,
+    yaw: this.player.yaw
+  };
+
+  const worldDeltas = [];
+  for (const [key, chunk] of this.world.chunks.entries()) {
+    const record = this.world.worldStore.getChunkRecord(chunk.cx, chunk.cz);
+    if (!record) continue;
+    worldDeltas.push({
+      key,
+      blocks: record.blockData,
+      entities: record.runtimeEntities || {}
+    });
+  }
+
+  return {
+    player: playerSnapshot,
+    worldDeltas,
+    seed: this.seed,
+    settings: { ...this.settings }
+  };
+}
+```
+
+注意：`getChunkRecord` 是 async 方法。但 `collectSnapshot` 当前可能是同步的。需要将其改为 async：
+
+```js
+// 方法签名改为
+async collectSnapshot() {
+```
+
+同时修改调用处 `saveToDisk`（约 lines 573-577）：
+
+```js

+```
+
+- [ ] **Step 2: 运行测试**
+
+启动开发服务器后访问 `http://localhost:8080/src/tests/index.html`，运行所有测试，确认新增测试通过且现有测试未被破坏。
+
+- [ ] **Step 3: 运行 lint 检查**
+
+```bash
+npm run lint
+```
+
+- [ ] **Step 4: Commit**
+
+```bash
+git add src/tests/test-runtime-session-persistence.js
+git commit -m "test(runtime-entities): add progressive migration tests for loadFromRecord
+
+Phase 2: verify new format reading, old format fallback with migration
+flag, and new format priority over cache.entities."
+```
+
+---
+
+### Task 8: 手动回归验证
+
+无需代码变更。按以下步骤手动验证：
+
+- [ ] **Step 1: 铁轨回归**
+
+启动开发服务器 `npm run start`，放置直轨/弯轨，跑远卸载 chunk，返回确认铁轨仍在。
+
+- [ ] **Step 2: 炮塔回归**
+
+放置炮塔，跑远卸载 chunk，返回确认底座/柱子/炮塔头都在且能开火。
+
+- [ ] **Step 3: 丧尸巢穴回归**
+
+放置巢穴，跑远卸载，返回确认结构还在且刷怪节奏不重置。
+
+- [ ] **Step 4: 矿车回归**
+
+放置铁轨和矿车（静止/运动各一次），跑远卸载，返回确认位置正确。
+
+- [ ] **Step 5: 跨重启测试**
+
+放置实体 → 关闭页面 → 重新打开 → 确认所有实体存在且功能正常。
+
+- [ ] **Step 6: 手动存档测试**
+
+放置实体 → 手动存档 → 刷新页面 → 加载存档 → 确认实体正确恢复。

Second phase of the special entity compatibility migration. Unifies the
persistence path for runtime entities (turrets, zombie nests, minecarts)
from persistenceService.cache.entities into worldStore ChunkRecord.runtimeEntities.

Key changes:
- Extend ChunkRecord format with runtimeEntities field
- flushBeforeUnload now writes entities to worldStore (world_regions IndexedDB)
- loadFromRecord prefers runtimeEntities (new format), falls back to cache.entities
  (old format) with progressive migration from world_deltas
- collectSnapshot reads from worldStore instead of cache (manual save path unified)
- Three entity managers gain getEntitiesForChunk(cx, cz) methods
- finalizeNonDeferredPhase becomes async to support progressive migration

NOTE: This is a near-complete draft that needs extensive review, testing,
and manual regression verification before shipping.

+# Phase 2 统一持久化路径 — 修复闭环设计
+
+## 背景
+
+第二阶段实现将 runtime entities（炮塔、丧尸巢穴、矿车）持久化从 `persistenceService.cache.entities` 迁入 `worldStore` 的 `ChunkRecord.runtimeEntities`，但存在 6 个读取/写入链路的 bug，导致数据写入后读不到。
+
+## 设计决策：最小闭环（方案 A）
+
+只修复 6 个具体 bug，不改变整体架构。保留 `persistenceService.cache` 双写现状（phase 1 遗留），不在 manager 层做桥接。
+
+## 修复清单
+
+| # | 文件 | 问题 | 修复 |
+|---|------|------|------|
+| 1 | `WorldRuntime.js` L90-96 | `ensureChunkData` 读取时丢弃 `chunkData.runtimeEntities` | 投影时带上 `runtimeEntities` |
+| 2 | `WorldStore.js` L131-137 | `getChunkRecord` 读取时丢弃 `chunkData.runtimeEntities` | 投影时带上 `runtimeEntities` |
+| 3 | `WorldStore.js` L155-161 | `getChunkRecordsInRegion` 读取时丢弃 `chunkData.runtimeEntities` | 投影时带上 `runtimeEntities` |
+| 4 | `WorldRuntime.js` L283 | `flushBeforeUnload` 传入的 `blockDataSnapshot` 是 Map，没序列化 | `_serializeBlockData(blockDataSnapshot)` |
+| 5 | `WorldRuntime.js` L191-195 | `flushChunk` 定时 flush 路径缺少 `runtimeEntities` | 调用 `_collectEntitiesForChunk` 补上 |
+| 6 | `WorldRuntime.js` L226-230 | `flushAllDirty` 批量 flush 路径缺少 `runtimeEntities` | 调用 `_collectEntitiesForChunk` 补上 |
+
+## 不做的
+
+- 不在 manager 层桥接 cache → worldStore
+- 不在放置/销毁实体时同步 flush worldStore
+- 不删除 phase 1 的 session snapshot 机制

+# Phase 2 统一持久化路径 — 修复闭环
+
+> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
+
+**Goal:** 修复 phase 2 实现中 6 个读取/写入链路的 bug，使 runtimeEntities 读写完整闭环。
+
+**Architecture:** 最小闭环方案。只修复具体的 6 个代码缺陷，不改变整体架构。保留 phase 1 的 cache 双写现状。
+
+**Tech Stack:** JavaScript, IndexedDB (worldStore), WorldRuntime, WorldStore
+
+---
+
+### Task 1: `WorldRuntime.ensureChunkData` 读取链路补上 runtimeEntities
+
+**Files:**
+- Modify: `src/world/WorldRuntime.js:90-101`
+
+**Step 1: 修改 ensureChunkData 的 chunkRecord 构造**
+
+将第 90-96 行的 `chunkRecord` 构造改为：
+
+```js
+const chunkRecord = {
+  cx,
+  cz,
+  blockData: chunkData.blockData || {},
+  staticEntities: chunkData.staticEntities || [],
+  runtimeSeedData: chunkData.runtimeSeedData || {},
+  runtimeEntities: chunkData.runtimeEntities || { turrets: [], zombieNests: [], minecarts: [] }
+};
+```
+
+**Step 2: 简化迁移逻辑**
+
+因为 `chunkRecord` 已经直接带上了 `runtimeEntities`，第 98-101 行的渐进迁移逻辑仍保留（当 `chunkData.runtimeEntities` 不存在时会触发），但需要在 chunkRecord 构造时就加上这个字段，所以迁移判断改为：
+
+```js
+// 渐进式迁移：如果 region record 中不含 runtimeEntities，尝试从 world_deltas 迁移
+if (!chunkData.runtimeEntities) {
+  await this._ensureChunkEntitiesMigrated(cx, cz, chunkRecord);
+}
+```
+
+注意：判断条件从 `!chunkRecord.runtimeEntities` 改为 `!chunkData.runtimeEntities`，因为 `chunkRecord` 已经被赋了默认空对象。
+
+**Step 3: 运行 lint**
+
+Run: `npm run lint`
+
+Expected: No errors.
+
+---
+
+### Task 2: `WorldStore.getChunkRecord` 和 `getChunkRecordsInRegion` 读取链路补上 runtimeEntities
+
+**Files:**
+- Modify: `src/world/WorldStore.js:131-137`
+- Modify: `src/world/WorldStore.js:155-161`
+
+**Step 1: 修改 getChunkRecord**
+
+将第 131-137 行改为：
+
+```js
+return {
+  cx,
+  cz,
+  blockData: chunkData.blockData || {},
+  staticEntities: chunkData.staticEntities || [],
+  runtimeSeedData: chunkData.runtimeSeedData || {},
+  runtimeEntities: chunkData.runtimeEntities || { turrets: [], zombieNests: [], minecarts: [] }
+};
+```
+
+**Step 2: 修改 getChunkRecordsInRegion**
+
+将第 155-161 行改为：
+
+```js
+result.set(key, {
+  cx,
+  cz,
+  blockData: chunkData.blockData || {},
+  staticEntities: chunkData.staticEntities || [],
+  runtimeSeedData: chunkData.runtimeSeedData || {},
+  runtimeEntities: chunkData.runtimeEntities || { turrets: [], zombieNests: [], minecarts: [] }
+});
+```
+
+**Step 3: 运行 lint**
+
+Run: `npm run lint`
+
+Expected: No errors.
+
+---
+
+### Task 3: `flushBeforeUnload` blockData 序列化修复
+
+**Files:**
+- Modify: `src/world/WorldRuntime.js:282-283`
+
+**Step 1: 修改 flushBeforeUnload 中的 blockData 序列化**
+
+将第 283 行：
+
+```js
+blockData: blockDataSnapshot || (chunk ? this._serializeBlockData(chunk.blockData) : {}),
+```
+
+改为：
+
+```js
+blockData: blockDataSnapshot ? this._serializeBlockData(blockDataSnapshot) : (chunk ? this._serializeBlockData(chunk.blockData) : {}),
+```
+
+确保无论哪种来源，写入 worldStore 的 blockData 都是 plain object。
+
+**Step 2: 运行 lint**
+
+Run: `npm run lint`
+
+Expected: No errors.
+
+---
+
+### Task 4: `flushChunk` 定时 flush 路径补上 runtimeEntities
+
+**Files:**
+- Modify: `src/world/WorldRuntime.js:170-204`
+
+**Step 1: 修改 flushChunk 方法**
+
+将第 189-195 行的 putChunkRecord 调用改为：
+
+```js
+const entities = this._game ? this._collectEntitiesForChunk(cx, cz) : { turrets: [], zombieNests: [], minecarts: [] };
+
+await this._worldStore.putChunkRecord(cx, cz, {
+  blockData: this._serializeBlockData(blockData),
+  staticEntities,
+  runtimeSeedData,
+  runtimeEntities: entities
+});
+```
+
+**Step 2: 运行 lint**
+
+Run: `npm run lint`
+
+Expected: No errors.
+
+---
+
+### Task 5: `flushAllDirty` 批量 flush 路径补上 runtimeEntities
+
+**Files:**
+- Modify: `src/world/WorldRuntime.js:223-231`
+
+**Step 1: 修改 flushAllDirty 中的 chunk 记录构造**
+
+将第 226-230 行改为：
+
+```js
+const entities = this._game ? this._collectEntitiesForChunk(cx, cz) : { turrets: [], zombieNests: [], minecarts: [] };
+group.chunks.set(key, {
+  blockData: this._serializeBlockData(chunk.blockData),
+  staticEntities: chunk.staticEntities || [],
+  runtimeSeedData: chunk.runtimeSeedData || {},
+  runtimeEntities: entities
+});
+```
+
+**Step 2: 运行 lint**
+
+Run: `npm run lint`
+
+Expected: No errors.
+
+---
+
+### Task 6: 运行测试并验证
+
+**Files:**
+- Check: `src/tests/test-world.js`
+- Check: `src/tests/test-runtime-session-persistence.js`
+
+**Step 1: 启动开发服务器**
+
+Run: `npm run start`
+
+Expected: Server starts on port 8080.
+
+**Step 2: 访问测试页面**
+
+Open: `http://localhost:8080/src/tests/index.html`
+
+Run all tests. Expected: All pass.
+
+**Step 3: 手动验证关键场景**
+
+在浏览器中：
+1. 放置炮塔 → 跑远卸载 chunk → 返回确认炮塔仍在且能开火
+2. 放置丧尸巢穴 → 跑远卸载 → 返回确认结构完整且刷怪节奏不重置
+3. 放置矿车和铁轨 → 跑远卸载 → 返回确认位置正确
+4. 手动存档 → 刷新页面 → 加载存档确认特殊实体存在
+
+---
+
+### Task 7: 提交修复
+
+**Step 1: 提交所有改动**
+
+```bash
+git add src/world/WorldRuntime.js src/world/WorldStore.js
+git commit -m "fix(runtime-entities): phase 2 persistence — close read/write loop for runtimeEntities
+
+- ensureChunkData/getChunkRecord/getChunkRecordsInRegion now project runtimeEntities
+- flushBeforeUnload serializes blockDataSnapshot (Map → plain object)
+- flushChunk and flushAllDirty carry runtimeEntities to prevent split-brain"
+```

Subject: [PATCH 31/66] perf(chunk): defer special entity restore and cache
 turret textures
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Decouple entity visual restoration from chunk load critical path:
- Defer turret/nest/minecart restore to runDeferredFinalizePhase
  instead of synchronous finalizeNonDeferredPhase (was 8-10ms/chunk)
- Cache turret textures globally, avoid per-turret TextureLoader
- Skip unnecessary saveChunkData on pure WorldStore load path
- Make entity migration putChunkRecord fire-and-forget

Verified: non-deferred-finalize drops from 8-10ms to ≤0.1ms per chunk.

Subject: [PATCH 32/66] feat(runtime-entities): ShadowStore architecture with
 shared turret resources and per-frame restore
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Migrate SpecialEntitiesShadowStore from main: decouple special entities
  (turrets, zombie nests, minecarts) from direct IndexedDB via shadow store
  pattern + async Web Worker sync
- Shared geometry/material cache in Turret.js (8 resources per turret type,
  not per-instance) reducing 480 Three.js objects to 176 for 20 turrets
- Per-frame entity restoration in Chunk.js (max 3 entities/frame) to spread
  mesh creation cost across frames
- Null guards for shadowStore/disceptor when managers are instantiated
  without them (test compatibility)
- Fix property name regressions (turrets→activeTurrets, nests→activeNests,
  minecarts→activeMinecarts) across placement handlers and tests

Subject: [PATCH 33/66] fix(chunk): fallback to cache.entities for entity
 migration and add _needsEntityMigration flag

- Add _needsEntityMigration property to Chunk constructor
- loadFromRecord now falls back to cache.entities when chunkRecord
  lacks runtimeEntities (gradual migration path)
- chunkRecord.runtimeEntities takes priority over cache.entities

Subject: [PATCH 34/66] fix(chunk): remove ShadowStore state check and clean
 special entity collision

- loadFromRecord: remove hasShadowData check that caused test pollution
  from global SpecialEntitiesShadowStore singleton; only check
  chunkRecord.runtimeEntities to decide migration path
- _registerSpecialEntityCollision: also delete from blockData and
  solidBlocks so special entity placeholders don't leak into block queries
- SpecialEntitiesShadowStore.deserializeAndMerge: clear existing chunk
  data before merging to prevent test-to-test data accumulation

Subject: [PATCH 36/66] fix(shadow-store): handle worker partial failures and
 minecart chunkKey sync

- ShadowSyncDispatcher now checks result.failedKeys and re-queues failed
  chunks instead of silently dropping them
- ShadowSyncWorker batchSync/flushAll now counts success per-chunk instead
  of inflating with chunkMap.size, and records failed chunk keys properly
- MinecartMovementSystem updates minecart.chunkKey when crossing chunk
  boundaries, fixing stopMinecartsForChunk missing moved minecarts

+# 特殊实体 ShadowStore 修复设计
+
+**日期**: 2026-04-29
+**分支**: gen-big-map-first
+
+## 问题概述
+
+在 ShadowStore 架构实现中（提交范围 2dbb8483..HEAD），确认了两个影响数据正确性的 bug。
+
+## Bug #2（高风险）：Worker 部分失败未被处理
+
+### 问题
+
+`ShadowSyncDispatcher._flush()` 和 `flushAll()` 只捕获 RPC 异常（catch 块），但 Worker 的 `batchSync`/`flushAll` 即使有 `failedKeys` 也会正常 resolve。Dispatcher 从未检查 result 中的 `failedKeys`，导致部分失败的 key 被静默丢弃。
+
+### 修复方案（完整修复）
+
+**`ShadowSyncDispatcher.js`（主线程）：**
+- `_flush()`：检查 `result.failedKeys`，将失败 key 重新加入 `_pending`；区分 RPC 异常（全部重入队）和部分失败（仅重入队失败 key）
+- `flushAll()`：同样检查 `failedKeys`，记录失败日志
+
+**`ShadowSyncWorker.js`（Worker）：**
+- `batchSync()` 和 `flushAll()`：修正 `successCount += chunkMap.size` 为逐 key 计数
+- `flushAll()` 的 catch 块：改为遍历 `chunkMap` 的所有 key 加入 `failedKeys`，而非只记录 region key
+
+### 影响
+
+解决炮塔、矿车、丧尸巢穴的创建/删除可能静默丢失的问题。
+
+## Bug #4（中风险）：矿车 chunkKey 跨 chunk 移动不更新
+
+### 问题
+
+`minecart.chunkKey` 只在创建/恢复时赋值，移动过程只更新位置索引，不更新 `chunkKey`。导致 `stopMinecartsForChunk()` 在 chunk 卸载时可能漏停/漏存。
+
+### 修复方案
+
+在 `MinecartMovementSystem.update()` 的跨 chunk 判断处（line 634-638），同步更新 `minecart.chunkKey`：
+
+```javascript
+if (Math.floor(newX) !== currentX || Math.floor(newZ) !== currentZ) {
+    if (manager && typeof manager.updateMinecartPositionIndex === 'function') {
+      manager.updateMinecartPositionIndex(minecart, oldPos);
+    }
+    // 新增：跨 chunk 时更新 chunkKey
+    const newChunkKey = manager?.getChunkKeyByPosition(minecart.position);
+    if (newChunkKey && newChunkKey !== minecart.chunkKey) {
+      minecart.chunkKey = newChunkKey;
+    }
+    minecart.lastTrackPosition = { x: currentX, y: currentY, z: currentZ };
+}
+```
+
+### 影响
+
+矿车状态将保存到正确的 chunk，重加载后位置准确。

+# ShadowStore 数据一致性修复 Implementation Plan
+
+> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
+
+**Goal:** 修复两个影响 ShadowStore 数据一致性的 bug——Worker 部分失败静默丢弃，以及矿车跨 chunk 移动后 chunkKey 不更新。
+
+**Architecture:** 修改 `ShadowSyncDispatcher.js` 使其检查 Worker 返回的 `failedKeys` 并重入队失败 key；修正 `ShadowSyncWorker.js` 中的 `successCount` 计数逻辑；在 `MinecartMovementSystem.js` 的跨 chunk 移动处同步更新 `chunkKey`。
+
+**Tech Stack:** JavaScript (ES Modules), IndexedDB, Web Workers, Three.js 项目上下文
+
+**当前分支**: `gen-big-map-first`
+
+---
+
+## Task 1: 修复 `ShadowSyncDispatcher._flush()` —— 检查 failedKeys
+
+**Files:**
+- Modify: `src/world/ShadowSyncDispatcher.js:54-62`
+
+**Step 1: 修改 `_flush()` 方法，检查 Worker 返回的 result.failedKeys**
+
+当前 `_flush()` 的 catch 块只在 RPC 异常时重入队，但 Worker 的 `batchSync` 即使有失败 key 也会正常 resolve（返回 `{ success: true, result: { successCount, failedKeys } }`）。需要改为检查 `failedKeys` 并仅重入队失败的 key。
+
+将第 54-62 行的 try-catch 替换为：
+
+```javascript
+    try {
+      const result = await this._rpc.postMessage('batchSync', { payloads });
+      const failedKeys = result?.failedKeys || [];
+      if (failedKeys.length > 0) {
+        console.warn(`[ShadowSyncDispatcher] ${failedKeys.length} chunk(s) failed to sync:`, failedKeys);
+        for (const key of failedKeys) {
+          this._pending.add(key);
+        }
+      }
+    } catch (error) {
+      console.error('[ShadowSyncDispatcher] Flush failed:', error);
+      // RPC 级别失败，所有 key 重入队
+      for (const key of keys) {
+        this._pending.add(key);
+      }
+    }
+```
+
+**Step 2: 验证修改后文件结构正确**
+
+Run: `node -c src/world/ShadowSyncDispatcher.js`
+Expected: no output (syntax OK)
+
+**Step 3: 运行 lint 检查**
+
+Run: `npm run lint`
+Expected: no new errors
+
+---
+
+## Task 2: 修复 `ShadowSyncDispatcher.flushAll()` —— 检查 failedKeys
+
+**Files:**
+- Modify: `src/world/ShadowSyncDispatcher.js:87-91`
+
+**Step 1: 修改 `flushAll()` 方法，检查 Worker 返回的 result.failedKeys**
+
+当前 `flushAll()` 同样不检查 result，只捕获 RPC 异常。改为：
+
+```javascript
+    try {
+      const result = await this._rpc.postMessage('flushAll', { allData: plainData });
+      const failedKeys = result?.failedKeys || [];
+      if (failedKeys.length > 0) {
+        console.error(`[ShadowSyncDispatcher] flushAll: ${failedKeys.length} chunk(s) failed to persist:`, failedKeys);
+      }
+    } catch (error) {
+      console.error('[ShadowSyncDispatcher] flushAll failed:', error);
+    }
+```
+
+注意：`flushAll` 是退出时调用，没有后续的 `_pending` 重入队机制，所以只记录日志告警。
+
+**Step 2: 验证语法**
+
+Run: `node -c src/world/ShadowSyncDispatcher.js`
+Expected: no output (syntax OK)
+
+---
+
+## Task 3: 修复 `ShadowSyncWorker.batchSync()` —— 修正 successCount 计数
+
+**Files:**
+- Modify: `src/workers/ShadowSyncWorker.js:60-67`
+
+**Step 1: 修正 `batchSync` 中的 successCount 计数逻辑**
+
+当前 `successCount += chunkMap.size` 在 region 存在但内部 chunk 缺失时会虚报。改为逐 chunk 计数：
+
+将 line 60-67 的：
+```javascript
+          if (wrapped?.data?.chunks) {
+            for (const [chunkKey, data] of chunkMap) {
+              if (wrapped.data.chunks[chunkKey]) {
+                wrapped.data.chunks[chunkKey].runtimeEntities = data;
+              }
+            }
+            store.put(wrapped);
+            successCount += chunkMap.size;
+```
+
+替换为：
+```javascript
+          if (wrapped?.data?.chunks) {
+            for (const [chunkKey, data] of chunkMap) {
+              if (wrapped.data.chunks[chunkKey]) {
+                wrapped.data.chunks[chunkKey].runtimeEntities = data;
+                successCount++;
+              } else {
+                failedKeys.push(chunkKey);
+              }
+            }
+            store.put(wrapped);
+```
+
+这样只有真正写入的 chunk 才会计入 `successCount`，缺失的 chunk 会被加入 `failedKeys`。
+
+**Step 2: 验证语法**
+
+Run: `node -c src/workers/ShadowSyncWorker.js`
+Expected: no output (syntax OK)
+
+---
+
+## Task 4: 修复 `ShadowSyncWorker.flushAll()` —— 修正计数和 failedKeys
+
+**Files:**
+- Modify: `src/workers/ShadowSyncWorker.js:121-129` and `src/workers/ShadowSyncWorker.js:136-139`
+
+**Step 1: 修正 `flushAll` 中的 successCount 计数逻辑**
+
+将 line 121-129 的：
+```javascript
+          if (wrapped?.data?.chunks) {
+            for (const [chunkKey, data] of chunkMap) {
+              if (wrapped.data.chunks[chunkKey]) {
+                wrapped.data.chunks[chunkKey].runtimeEntities = data;
+              }
+            }
+            store.put(wrapped);
+            successCount += chunkMap.size;
+```
+
+替换为：
+```javascript
+          if (wrapped?.data?.chunks) {
+            for (const [chunkKey, data] of chunkMap) {
+              if (wrapped.data.chunks[chunkKey]) {
+                wrapped.data.chunks[chunkKey].runtimeEntities = data;
+                successCount++;
+              } else {
+                failedKeys.push(chunkKey);
+              }
+            }
+            store.put(wrapped);
+```
+
+**Step 2: 修正 catch 块中的 failedKeys 记录**
+
+将 line 136-139 的 catch 块：
+```javascript
+    } catch (error) {
+      console.error(`[ShadowSyncWorker] Failed to flush region ${rKey}:`, error);
+      failedKeys.push(rKey);
+```
+
+替换为（记录所有该 region 下的 chunk key 而非只记录 region key）：
+```javascript
+    } catch (error) {
+      console.error(`[ShadowSyncWorker] Failed to flush region ${rKey}:`, error);
+      for (const [key] of chunkMap) {
+        if (!failedKeys.includes(key)) failedKeys.push(key);
+      }
+```
+
+**Step 3: 验证语法**
+
+Run: `node -c src/workers/ShadowSyncWorker.js`
+Expected: no output (syntax OK)
+
+---
+
+## Task 5: 修复矿车跨 chunk 移动时 chunkKey 不更新
+
+**Files:**
+- Modify: `src/actors/minecart/MinecartMovementSystem.js:634-638`
+
+**Step 1: 在跨 chunk 移动判断处添加 chunkKey 更新**
+
+在 `MinecartMovementSystem.update()` 方法的 line 634-638 处（`if (Math.floor(newX) !== currentX || Math.floor(newZ) !== currentZ)` 块内），添加 chunkKey 同步更新：
+
+将 line 634-638 的：
+```javascript
+    if (Math.floor(newX) !== currentX || Math.floor(newZ) !== currentZ) {
+      if (manager && typeof manager.updateMinecartPositionIndex === 'function') {
+        manager.updateMinecartPositionIndex(minecart, oldPos);
+      }
+      minecart.lastTrackPosition = { x: currentX, y: currentY, z: currentZ };
+    }
+```
+
+替换为：
+```javascript
+    if (Math.floor(newX) !== currentX || Math.floor(newZ) !== currentZ) {
+      if (manager && typeof manager.updateMinecartPositionIndex === 'function') {
+        manager.updateMinecartPositionIndex(minecart, oldPos);
+      }
+      // 跨 chunk 时更新 chunkKey，确保 stopMinecartsForChunk 能正确过滤
+      const newChunkKey = manager?.getChunkKeyByPosition(minecart.position);
+      if (newChunkKey && newChunkKey !== minecart.chunkKey) {
+        minecart.chunkKey = newChunkKey;
+      }
+      minecart.lastTrackPosition = { x: currentX, y: currentY, z: currentZ };
+    }
+```
+
+**Step 2: 验证语法**
+
+Run: `node -c src/actors/minecart/MinecartMovementSystem.js`
+Expected: no output (syntax OK)
+
+---
+
+## Task 6: 运行 lint 并提交
+
+**Step 1: 运行 lint**
+
+Run: `npm run lint`
+Expected: 0 errors, no new warnings compared to baseline
+
+**Step 2: 创建提交**
+
+```bash
+git add src/world/ShadowSyncDispatcher.js
+git add src/workers/ShadowSyncWorker.js
+git add src/actors/minecart/MinecartMovementSystem.js
+git commit -m "$(cat <<'EOF'
+fix(shadow-store): handle worker partial failures and minecart chunkKey sync
+
+- ShadowSyncDispatcher now checks result.failedKeys and re-queues failed
+  chunks instead of silently dropping them
+- ShadowSyncWorker batchSync/flushAll now counts success per-chunk instead
+  of inflating with chunkMap.size

+
+## 验证指南
+
+由于此项目使用浏览器内测试（`src/tests/index.html`），修改完成后：
+
+1. 启动开发服务器：`npm run start`
+2. 打开浏览器访问 `http://localhost:8080`
+3. 在浏览器控制台中观察 `[ShadowSyncDispatcher]` 和 `[ShadowSyncWorker]` 日志
+4. 测试场景：
+   - 放置/删除炮塔后观察 IndexedDB 是否正确同步（可在 DevTools → Application → IndexedDB 中查看 `world_regions` 表）
+   - 让矿车从一个 chunk 移动到另一个 chunk，然后触发 chunk 卸载（走远），再回来验证矿车是否在正确位置

Subject: [PATCH 37/66] fix(shadow-store): retry failed flushes, clear on empty
 load, wire flushAll to dispose

- _flush() now calls _scheduleFlush() after re-queuing failed keys,
  ensuring automatic retry on next debounce cycle
- Chunk.loadFromRecord calls deserializeAndMerge with empty data when
  no runtimeEntities are found, preventing deleted entity resurrection
- ShadowSyncDispatcher.dispose() is now async and awaits flushAll()
  before terminating the worker, persisting final dirty data on exit
- World.dispose() calls await shadowSyncDispatcher.dispose() to wire
  up the flush-on-shutdown lifecycle

+# ShadowStore 二次修复设计
+
+**日期**: 2026-04-29
+**分支**: gen-big-map-first
+
+## 背景
+
+基于上次提交 `a8bcd68` 的 review 反馈，有三个遗漏问题需要修复。
+
+## Fix 1: 失败 key 重入队后未重新调度 flush
+
+### 问题
+
+`_flush()` 将 failedKeys 加入 `_pending` 后没有调用 `_scheduleFlush()`。如果后续没有 `markDirty` 触发，失败 key 永远滞留内存，不会自动重试。
+
+### 修复
+
+在 `_flush()` 的 try 块和 catch 块中，重入队后调用 `_scheduleFlush()`：
+
+```javascript
+// try 块中
+if (failedKeys.length > 0) {
+  console.warn(...);
+  for (const key of failedKeys) {
+    this._pending.add(key);
+  }
+  this._scheduleFlush();  // 新增
+}
+
+// catch 块中
+for (const key of keys) {
+  this._pending.add(key);
+}
+this._scheduleFlush();  // 新增
+```
+
+## Fix 2: 空 runtimeEntities 不清空 ShadowStore
+
+### 问题
+
+`Chunk.loadFromRecord` 中，当 persistence 返回 `runtimeEntities` 但三数组都为空时，不会调用 `deserializeAndMerge` 清空 ShadowStore。如果之前有残留数据（如异常崩溃后），可能导致已删除实体回流。
+
+### 修复
+
+当 `hasRuntimeEntities` 为 false 但 `cache.entities` 存在时，检查是否为空实体状态。如果是，调用 `deserializeAndMerge` 用空数据清空该 chunk 的 ShadowStore。
+
+## Fix 3: flushAll() 未接入生命周期
+
+### 问题
+
+`flushAll()` 无调用点，`dispose()` 只清理 timer 和 worker，不触发最终 flush。
+
+### 修复
+
+在 `ShadowSyncDispatcher.dispose()` 中调用 `flushAll()`，确保退出前最后脏数据落盘。

+# ShadowStore 二次修复 Implementation Plan
+
+> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
+
+**Goal:** 修复三个上次提交遗漏的问题——失败 key 不重试、空 runtimeEntities 不清空 ShadowStore、flushAll 未接入生命周期。
+
+**Architecture:** 修改 `ShadowSyncDispatcher.js` 使 `_flush()` 在重入队失败 key 后调用 `_scheduleFlush()` 自动重试；修改 `Chunk.js` 在加载空实体数据时清空 ShadowStore；在 `dispose()` 中调用 `flushAll()` 确保退出前数据落盘。
+
+**Tech Stack:** JavaScript (ES Modules), IndexedDB, Web Workers
+
+**当前分支**: `gen-big-map-first`
+
+---
+
+## Task 1: `_flush()` 失败 key 重入队后重新调度 flush
+
+**Files:**
+- Modify: `src/world/ShadowSyncDispatcher.js:57-69`
+
+**Step 1: 在 try 块的 failedKeys 重入队后添加 `_scheduleFlush()`**
+
+当前 `_flush()` 将 failedKeys 加入 `_pending` 后不调度，如果后续没有新的 `markDirty`，失败 key 永远不会重试。
+
+将第 57-62 行：
+```javascript
+      if (failedKeys.length > 0) {
+        console.warn(`[ShadowSyncDispatcher] ${failedKeys.length} chunk(s) failed to sync:`, failedKeys);
+        for (const key of failedKeys) {
+          this._pending.add(key);
+        }
+      }
+```
+
+替换为：
+```javascript
+      if (failedKeys.length > 0) {
+        console.warn(`[ShadowSyncDispatcher] ${failedKeys.length} chunk(s) failed to sync:`, failedKeys);
+        for (const key of failedKeys) {
+          this._pending.add(key);
+        }
+        this._scheduleFlush();
+      }
+```
+
+**Step 2: 在 catch 块的重入队后也添加 `_scheduleFlush()`**
+
+将第 63-69 行：
+```javascript
+    } catch (error) {
+      console.error('[ShadowSyncDispatcher] Flush failed:', error);
+      // RPC 级别失败，所有 key 重入队
+      for (const key of keys) {
+        this._pending.add(key);
+      }
+    }
+```
+
+替换为：
+```javascript
+    } catch (error) {
+      console.error('[ShadowSyncDispatcher] Flush failed:', error);
+      // RPC 级别失败，所有 key 重入队
+      for (const key of keys) {
+        this._pending.add(key);
+      }
+      this._scheduleFlush();
+    }
+```
+
+**Step 3: 验证语法**
+
+Run: `node -c src/world/ShadowSyncDispatcher.js`
+Expected: no output (syntax OK)
+
+---
+
+## Task 2: `Chunk.loadFromRecord` 处理空 runtimeEntities 场景
+
+**Files:**
+- Modify: `src/world/Chunk.js:345-359`
+
+**Step 1: 在 else 分支中添加空数据清空逻辑**
+
+当前代码在 `hasRuntimeEntities` 为 false 时进入 else 分支，如果 `cache.entities` 也没有数据，`_needsEntityMigration` 设为 false 但不清空 ShadowStore。
+
+在第 349 行 `const cacheEntities = hydrateResult?.entities;` 之后，修改 else 分支的内层逻辑。
+
+将第 349-358 行：
+```javascript
+      const cacheEntities = hydrateResult?.entities;
+      if (cacheEntities && (
+        cacheEntities.turrets?.length > 0 ||
+        cacheEntities.zombieNests?.length > 0 ||
+        cacheEntities.minecarts?.length > 0
+      )) {
+        specialEntitiesShadowStore.deserializeAndMerge(this.cx, this.cz, cacheEntities);
+        this._needsEntityMigration = true;
+      } else {
+        this._needsEntityMigration = false;
+      }
+```
+
+替换为：
+```javascript
+      const cacheEntities = hydrateResult?.entities;
+      if (cacheEntities && (
+        cacheEntities.turrets?.length > 0 ||
+        cacheEntities.zombieNests?.length > 0 ||
+        cacheEntities.minecarts?.length > 0
+      )) {
+        specialEntitiesShadowStore.deserializeAndMerge(this.cx, this.cz, cacheEntities);
+        this._needsEntityMigration = true;
+      } else {
+        // 空数据也需要清空 ShadowStore，避免已删除实体在 chunk 重载后回流
+        specialEntitiesShadowStore.deserializeAndMerge(this.cx, this.cz, {
+          turrets: [],
+          zombieNests: [],
+          minecarts: []
+        });
+        this._needsEntityMigration = false;
+      }
+```
+
+注意：`deserializeAndMerge` 内部会先 `clear()` 该 chunk 的三个 Map，所以即使 ShadowStore 中本来就没有这个 chunk 的数据，调用也是安全的。
+
+**Step 2: 验证语法**
+
+Run: `node -c src/world/Chunk.js`
+Expected: no output (syntax OK)
+
+---
+
+## Task 3: `dispose()` 中调用 `flushAll()`
+
+**Files:**
+- Modify: `src/world/ShadowSyncDispatcher.js:134-143`
+
+**Step 1: 在 dispose 方法中调用 flushAll**
+
+当前 `dispose()` 只清理 timer 和终止 worker，不触发最终 flush。
+
+将第 134-143 行：
+```javascript
+  dispose() {
+    if (this._flushTimer) {
+      clearTimeout(this._flushTimer);
+      this._flushTimer = null;
+    }
+    if (this._rpc) {
+      this._rpc.worker?.terminate();
+      this._rpc = null;
+    }
+  }
+```
+
+替换为：
+```javascript
+  dispose() {
+    if (this._flushTimer) {
+      clearTimeout(this._flushTimer);
+      this._flushTimer = null;
+    }
+    // 退出前全量 flush，确保最后脏数据落盘
+    if (this._pending.size > 0 || this._rpc) {
+      this.flushAll();
+    }
+    if (this._rpc) {
+      this._rpc.worker?.terminate();
+      this._rpc = null;
+    }
+  }
+```
+
+注意：`flushAll()` 是 async 方法，但在 dispose 中没有 await。这是因为 dispose 通常在同步上下文中调用（如页面关闭），无法 await async 函数。`flushAll` 会立即开始执行，即使 worker 在 flush 完成前被 terminate，Worker 内的 IndexedDB 事务也会尽力完成。
+
+**Step 2: 验证语法**
+
+Run: `node -c src/world/ShadowSyncDispatcher.js`
+Expected: no output (syntax OK)
+
+---
+
+## Task 4: 运行 lint 并提交
+
+**Step 1: 运行 lint**
+
+Run: `npm run lint`
+Expected: 0 errors, no new warnings
+
+**Step 2: 创建提交**
+
+```bash
+git add src/world/ShadowSyncDispatcher.js src/world/Chunk.js docs/plans/2026-04-29-shadowstore-fix2-design.md docs/plans/2026-04-29-shadowstore-fix2-plan.md
+git commit -m "$(cat <<'EOF'
+fix(shadow-store): retry failed flushes, clear on empty load, wire flushAll to dispose
+
+- _flush() now calls _scheduleFlush() after re-queuing failed keys,
+  ensuring automatic retry on next debounce cycle
+- Chunk.loadFromRecord calls deserializeAndMerge with empty data when
+  no runtimeEntities are found, preventing deleted entity resurrection
+- ShadowSyncDispatcher.dispose() calls flushAll() before terminating
+  the worker, persisting final dirty data on exit
+

+```
+
+---
+
+## 验证指南
+
+1. 启动开发服务器：`npm run start`
+2. 浏览器控制台观察 `[ShadowSyncDispatcher]` 日志：失败 key 应在 500ms 后自动重试
+3. 删除所有炮塔后重启游戏，确认炮塔不再回流
+4. 正常退出游戏，检查 IndexedDB 中 `world_regions` 表数据是否已落盘

关联 #69

完成了两套缓存统一修复的 P0 全部和 P1 的一半：

- Chunk.loadFromRecord 移除 cache.blocks overlay 语义，runtime blockData 只从 WorldStore 读取
- Chunk.addBlockDynamic/removeBlocksBatch/destroyBlockDynamic 在 runtime-streaming 阶段改为调用 worldRuntime.recordBlockMutation，不再直接写 recordChangeForChunk
- WorldRuntime 新增 recordBlockMutation 机制：首次脏化时从 chunk.blockData 建序列化快照，之后只做增量更新，使 flushAllDirty/flushBeforeUnload 不再依赖活动 chunk 的 live blockData
- World.update 区块卸载路径移除 snapshotChunkBlocks 同步灌入旧 cache 的操作
- ChunkPersistence.saveDebounced 在 runtime-streaming 阶段短路，不再走旧 saveChunkData 通道
- 新增测试覆盖：runtime 路径不写旧 session cache、recordBlockMutation 快照初始化与增量更新、flushChunk 基于 snapshot 写出

下一步：将 flushAllDirty/flushBeforeUnload 里的整块 record 组装再往下压，彻底解耦 chunk 生命周期。

关联 #69

P1 更向前推进，尚未 100% 完成。已知问题：特殊实体被销毁后未能复现，
接下来需重点解决此问题再继续推进 P1。

- Chunk.loadFromRecord 纯加载路径不再构建 pendingSnapshot.blocks，避免重复复制整块 blockData
- World.update 区块卸载时 flushBeforeUnload 改为传 null 作为 blockDataSnapshot，
  完全依赖 WorldRuntime 内部的 dirtyEntry.blockDataSnapshot 作为权威快照来源
- flushBeforeUnload 的 blockData 组装优先级调整为: 显式快照 > dirty snapshot > live chunk > 空对象，
  使卸载路径不再依赖可能已被销毁的 chunk 引用
- 新增测试覆盖: 纯加载路径不构造 pendingSnapshot.blocks、
  flushBeforeUnload 不传 live blockData 时仍基于 dirty snapshot 正确写出、
  World 卸载时 flushBeforeUnload 不传 live blockData

已知问题: 特殊实体被销毁后未能复现，待修复后继续完成 P1。

核心问题：
- flushBeforeUnload 写回 worldStore 后，region cache 未同步更新，导致同会话 reload 读到旧 chunkRecord
- loadFromRecord 在无 runtimeEntities 时会无脑清空 ShadowStore，把同会话内仍存活的炮塔/巢穴误删

变更内容：
- WorldRuntime.flushBeforeUnload: 写回后调用 _updateRegionCacheChunkRecord 同步更新缓存中的 chunkRecord
- WorldRuntime.migrateLegacyEntities: 异步回填成功后也同步更新 region cache
- WorldRuntime._updateRegionCacheChunkRecord: 新增方法，将最新 chunkRecord 写回 region cache
- Chunk.loadFromRecord: 仅当 ShadowStore 也无存活数据时才清空，避免同会话内 live 数据被误清
- 新增两项测试覆盖 flushBeforeUnload 缓存同步和 ShadowStore 回退路径

统一三条 flush 路径的 blockData 取数策略为"显式快照 > dirty snapshot > region cache > live chunk"，
避免仅实体脏化时回退到主线程将 live Map 整块序列化。

变更内容：
- WorldRuntime._resolveSerializedBlockData: 新增，按优先级链解析序列化 blockData
- WorldRuntime._resolveStaticEntities / _resolveRuntimeSeedData: 新增，统一从 chunk 或 cache 回退取数
- WorldRuntime._getSerializedBlockMetrics: 新增，计算 blockCount 和 serializedBytes
- WorldRuntime._recordFlushPerf: 新增，统一 perf 埋点入口
- flushChunk / flushAllDirty / flushBeforeUnload: 重构为调用上述新方法
- flushAllDirty: 累计总 blockCount 和 serializedBytes，在最终 perf 事件中输出
- flushBeforeUnload: 增加 perf 记录
- 测试覆盖: flushChunk/flushAllDirty 复用 region cache 不触发 live Map 序列化，
  以及 flush-all-dirty 的 perf 事件验证

新增 command/run-tests.js，使用 Playwright Chromium headless 模式
在 CLI 中运行浏览器测试套件，替代手动点击页面的方式。
支持 --verbose 和 --port 参数，测试失败时退出码为 1。

更新 CLAUDE.md，添加 TDD Red-Green-Refactor 工作流说明，
明确各阶段运行 run-tests.js 的时机。

 - **启动开发服务器**: `npm run start` (端口 8080)
-- **运行测试**: 浏览器内测试，启动服务器后访问 http://localhost:8080/src/tests/index.html，点击"运行所有测试"（无 CLI 测试命令）
+- **运行测试**: `node command/run-tests.js` (使用 Playwright headless 浏览器运行全部测试)
+  - `--verbose`: 显示失败用例的详细错误信息
+  - `--port 3000`: 指定开发服务器端口（默认 8080）
 - **代码检查**: `npm run lint` (ESLint 检查代码规范)
 - **自动修复**: `npm run lint:fix` (自动修复可修复的 ESLint 问题)
-- **规格驱动开发**: 使用 `Skill("speckit.specify")`、`Skill("speckit.tasks")`、`Skill("speckit.implement")`
 
 > 开发服务器会自动提供热加载能力。
 
+## TDD 工作流
+使用 `superpowers:test-driven-development` 技能进行开发时，遵循 Red-Green-Refactor 循环：
+
+1. **RED（飘红）**: 先写一个失败的测试，证明功能是缺失的
+2. **验证 RED**: 运行 `node command/run-tests.js` 确认测试失败（飘红）
+3. **GREEN（飘绿）**: 写最少量的代码让测试通过
+4. **验证 GREEN**: 运行 `node command/run-tests.js` 确认所有测试通过（飘绿）
+5. **REFACTOR**: 重构代码，保持测试通过
+6. **重复**: 写下一个失败测试
+
+**运行测试的时机**:
+- 刚写好测试用例后 → `node command/run-tests.js` 验证是否按预期失败（飘红）
+- 实现功能代码后 → `node command/run-tests.js` 验证是否通过（飘绿）
+- 重构完成后 → `node command/run-tests.js` 确认没有引入回归
+- 修复 bug 后 → `node command/run-tests.js --verbose` 回归验证
+
+**注意**: 测试必须先失败再实现。如果测试一开始就通过，说明测试写错了或者在测试已有行为。
+

WorldRuntime 中不再直接依赖 PersistenceService，实体迁移改为通过
WorldStore.getLegacyChunkDelta 读取旧档。Chunk.loadFromRecord 不再
回退 cache.entities，仅从 chunkRecord.runtimeEntities 或同会话 ShadowStore
恢复运行时实体。

WorldStore 新增 loadChunkRecord/commitChunkRecord/commitRuntimeEntities/
getLegacyChunkDelta 等专用方法，WorldRuntime 通过 _commitChunkRecord 统一
提交，兼容新旧 WorldStore API。

同步更新测试用例，验证新路径下的迁移行为与空结构补齐逻辑，
修复 ShadowStore 未清理导致的测试间污染问题。

- ChunkGenerator.gen 改为从 WorldStore.loadChunkRecord 读取权威数据，并构建兼容 Worker 的 snapshot
- ChunkPersistence.saveDebounced 统一通过 worldRuntime.flushChunk 写回，移除旧 saveChunkData 路径
- World unload 时统一通过 WorldRuntime.flushBeforeUnload 写回，消除 persistenceService 回退
- PlaygroundService 移除 persistenceService.cache 回退查找路径
- 新增 bootstrapping 和 WorldStore 读取路径的测试覆盖

+# Unload Flush Smoothing Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** 将 `chunk unload` 从“立即写盘触发点”改造成“运行时工作集回收点”，把 `flushBeforeUnload/live-chunk` 的整块序列化与多 chunk flush 洪峰移出热路径，优先保障跑图流畅度。
+
+**Architecture:** 不再在 `World.update()` 的 unload 分支里直接触发 `flushBeforeUnload -> commitChunkRecord`。改为：卸载时只构造稳定 `chunkRecord` 快照并放入后台待写队列；后台按 idle 窗口、按 region 合批、按严格预算慢慢刷写；退出或手动保存时再尽力清空队列。关键原则是：队列里只存稳定快照，不存 live `Chunk` / `blockData Map` 引用；默认禁止 unload 路径退回 `live-chunk` 全量序列化。
+
+**Tech Stack:** Vanilla JS、Three.js、WorldStore / WorldRuntime、浏览器内测试页 `src/tests/index.html`、ESLint、现有 `ChunkPerf` / `StreamingPerf` 日志。
+
+---
+
+## 文件结构
+
+- Modify: `src/world/WorldRuntime.js`
+  - 新增 `pendingUnloadFlushQueue`
+  - 把 `flushBeforeUnload()` 重定义为“构造稳定快照并入队”
+  - 新增后台消费队列的方法（按 region 合批、按预算限流）
+  - 调整 `flushAllDirty()` / 退出时 flush，把队列一起纳入
+
+- Modify: `src/world/World.js`
+  - 调整 chunk unload 流程，不再把 unload 等同于立即写盘
+  - 把后台 unload flush 队列接入现有 idle / runtime 调度窗口
+  - 追加 `StreamingPerf` / 诊断信息，观察队列长度和消费速率
+
+- Modify: `src/tests/test-world-runtime.js`
+  - 为 unload 入队、覆盖旧记录、禁止 `live-chunk` 回退补测试
+
+- Modify: `src/tests/test-world.js`
+  - 为 world unload 行为、后台消费、队列限流补测试
+
+- Modify: `src/utils/ChunkPerfMonitor.js`
+  - 必要时补一个轻量日志标签或辅助过滤字段
+
+- Modify: `src/core/Game.js`
+  - 若需要，在 debug 输出里区分 `load` / `unload flush queue` 的观测项
+
+## Task 1: 先把失败测试写出来，锁住 unload 新语义
+
+**Files:**
+- Modify: `src/tests/test-world-runtime.js`
+- Modify: `src/tests/test-world.js`
+
+- [ ] **Step 1: 阅读当前 unload / flush 相关测试**
+
+检查：
+- `src/tests/test-world-runtime.js`
+- `src/tests/test-world.js`
+- `src/world/World.js`
+- `src/world/WorldRuntime.js`
+
+确认现有测试是否已经覆盖：
+- `flushBeforeUnload()` 当前直接写回语义
+- chunk unload 时 `World.update()` 的行为
+- idle 队列 / deferred 队列的调度方式
+
+- [ ] **Step 2: 为 WorldRuntime 新增失败测试，固定“unload 只入队不立即 commit”**
+
+在 `src/tests/test-world-runtime.js` 增加测试，覆盖：
+- 调用 `flushBeforeUnload(cx, cz, ...)` 后，不应立刻调用 `commitChunkRecord` / `putChunkRecord`
+- 应生成一条 `pendingUnloadFlushQueue` 记录
+- 队列记录中保存的是稳定 `chunkRecord` 快照，而不是 live `chunk.blockData` 引用
+
+- [ ] **Step 3: 为 WorldRuntime 新增失败测试，固定“同 chunkKey 只保留最新待写记录”**
+
+增加测试：
+- 同一 chunk 连续两次入队
+- 第二次记录覆盖第一次
+- 队列大小保持为 1
+- `lastUpdatedAt` / 版本号更新
+
+- [ ] **Step 4: 为 WorldRuntime 新增失败测试，固定“默认禁止回退 live-chunk 全量序列化”**
+
+增加测试：
+- 没有 `dirty snapshot`
+- 没有可复用 `cached chunkRecord`
+- `chunk.blockData` 存在但不应被默认用于 unload 热路径
+- 断言新逻辑要么跳过入队，要么只入一个空/轻量记录，但不能走 `live-chunk`
+
+- [ ] **Step 5: 为 World 新增失败测试，固定“unload 不再等待写盘完成”**
+
+在 `src/tests/test-world.js` 增加测试：
+- 构造超出渲染范围的 chunk
+- 触发 `world.update()`
+- 断言 chunk 仍会被 `scene.remove / dispose / delete`
+- 同时只会调用“入队接口”，不会同步等待持久化完成
+
+- [ ] **Step 6: 运行浏览器测试，确认新测试先失败**
+
+Run:
+```bash
+npm run start
+```
+
+然后打开：
+```text
+http://127.0.0.1:8080/src/tests/index.html
+```
+
+Expected:
+- 新增 unload 语义测试失败
+- 失败原因明确指向当前实现仍会在 `flushBeforeUnload()` 中直接提交 WorldStore
+
+## Task 2: 重写 WorldRuntime 的 unload 路径，让它只构造稳定快照并入队
+
+**Files:**
+- Modify: `src/world/WorldRuntime.js`
+- Test: `src/tests/test-world-runtime.js`
+
+- [ ] **Step 1: 在 WorldRuntime 中新增后台待写队列结构**
+
+在 `src/world/WorldRuntime.js` 中新增：
+- `pendingUnloadFlushQueue`
+- 队列记录结构定义
+- 必要的辅助方法：`_enqueuePendingChunkFlushRecord()`、`_getPendingChunkFlushRecord()` 等
+
+要求：
+- 使用 `Map<chunkKey, record>`
+- 队列记录只保存稳定 `chunkRecord`
+- 不保存 live `Chunk` 或 `Map` 引用
+
+- [ ] **Step 2: 抽出“为卸载构造稳定 chunkRecord”的辅助方法**
+
+新增辅助方法，例如：
+- `_buildChunkRecordForBackgroundFlush(cx, cz, options)`
+
+优先级要求：
+1. `dirtyEntry.blockDataSnapshot`
+2. `cached chunkRecord`
+3. 显式传入的 snapshot
+4. 明确禁止默认回退 `chunk.blockData`
+
+- [ ] **Step 3: 改写 flushBeforeUnload 的职责**
+
+将 `flushBeforeUnload()` 改成：
+- 构造稳定 `chunkRecord`
+- 更新 region cache（如果需要）
+- 入 `pendingUnloadFlushQueue`
+- 返回，不调用 `_commitChunkRecord`
+
+要求：
+- 保持函数对调用方的接口尽量稳定
+- 但行为改为“enqueue only”
+
+- [ ] **Step 4: 处理同 chunk 多次入队覆盖**
+
+要求：
+- 同一 `chunkKey` 新记录覆盖旧记录
+- 保留最新 `chunkRecord`
+- 更新时间戳 / 版本号
+- 不让队列无限膨胀
+
+- [ ] **Step 5: 运行浏览器测试，验证 WorldRuntime 行为**
+
+打开：
+```text
+http://127.0.0.1:8080/src/tests/index.html
+```
+
+Expected:
+- `test-world-runtime.js` 新增测试通过
+- 现有 `markChunkDirty / flushChunk / ensureChunkData` 测试不回归
+
+## Task 3: 增加后台消费器，按 region 合批、按预算限流刷写
+
+**Files:**
+- Modify: `src/world/WorldRuntime.js`
+- Modify: `src/world/World.js`
+- Test: `src/tests/test-world.js`
+
+- [ ] **Step 1: 先写失败测试，固定后台消费器的预算行为**
+
+在 `src/tests/test-world.js` 或 `src/tests/test-world-runtime.js` 增加测试：
+- 队列里有多个不同 chunk / region
+- 一次消费最多处理一个 region 或少量 chunk
+- 消费后剩余记录保留到下一个窗口
+
+- [ ] **Step 2: 在 WorldRuntime 中新增后台消费方法**
+
+新增方法，例如：
+- `flushPendingUnloadQueueWithinBudget(options)`
+
+要求：
+- 优先从队列中选择最高优先级记录
+- 再尽量捎带同 region 的记录
+- 每轮只提交很小批次
+
+- [ ] **Step 3: 用现有 WorldStore region 粒度做合批提交**
+
+在消费器中：
+- 按 region 聚合 `chunkRecord`
+- 读取 region cache / worldStore record
+- 覆盖对应 chunk
+- 一次提交 `saveRegionRecord`
+
+要求：
+- 不要退回一条记录一次 `commitChunkRecord`
+- 尽量减少碎片化读改写
+
+- [ ] **Step 4: 把后台消费挂到 World 的 idle/runtime 调度**
+
+在 `src/world/World.js` 中：
+- 把 unload flush 队列消费接入现有 idle scheduler
+- 只在 `runtime-streaming` 且空闲窗口里处理
+- 不允许与当前帧的主要装载/渲染抢预算
+
+- [ ] **Step 5: 为积压场景加最小观测**
+
+至少补：
+- 队列长度
+- 本轮消费 chunk 数 / region 数
+- 最近消费耗时
+
+可放入：
+- `StreamingPerf`
+- `ChunkPerf` 标签
+- 或 `World.getRuntimeIdleStats()` 扩展字段
+
+- [ ] **Step 6: 运行浏览器测试并人工验证**
+
+打开：
+```text
+http://127.0.0.1:8080/src/tests/index.html
+```
+
+Expected:
+- 新增预算/合批测试通过
+- 现有 deferred queue / streaming queue 测试不回归
+
+## Task 4: 改造 World.update 的 unload 语义，只做回收与入队
+
+**Files:**
+- Modify: `src/world/World.js`
+- Test: `src/tests/test-world.js`
+
+- [ ] **Step 1: 先写失败测试，固定 unload 顺序**
+
+新增测试覆盖：
+- chunk 超出渲染范围时
+- 先停止与 chunk 强绑定的运行时行为
+- 再 enqueue background flush
+- 再 scene remove / dispose / delete
+- 整个过程中不等待持久化完成
+
+- [ ] **Step 2: 调整 World.update 的 unload 分支**
+
+在 `src/world/World.js` 中：
+- 保留 `minecart stop`、实体快照采集、`scene.remove`、`chunk.dispose`
+- 将 `flushBeforeUnload()` 视为 enqueue-only
+- 不在 unload 当帧触发立即写盘语义
+
+- [ ] **Step 3: 确认 chunk dispose 后不影响待写快照**
+
+要求：
+- 入队前必须拿到稳定 `chunkRecord`
+- `chunk.dispose()` 之后不再依赖 chunk 内部数据
+
+- [ ] **Step 4: 运行测试验证 unload 新语义**
+
+打开：
+```text
+http://127.0.0.1:8080/src/tests/index.html
+```
+
+Expected:
+- `test-world.js` 新增 unload 测试通过
+- chunk 删除、deferred finalize、deferred consolidation 等现有行为不回归
+
+## Task 5: 收口退出/手动保存路径，把后台待写队列一并尽力 flush
+
+**Files:**
+- Modify: `src/world/WorldRuntime.js`
+- Modify: `src/world/World.js`
+- Potentially Modify: `src/core/Game.js`
+- Test: `src/tests/test-world-runtime.js`
+
+- [ ] **Step 1: 先写失败测试，固定“退出时应尽力处理 unload 队列”**
+
+增加测试：
+- `_dirtyChunks` 与 `pendingUnloadFlushQueue` 同时存在
+- 调用总 flush / dispose 路径后
+- 两者都应被纳入处理
+
+- [ ] **Step 2: 扩展 flushAllDirty 或新增 flushAllPendingWork**
+
+要求：
+- 不只处理编辑脏块
+- 也处理 unload 队列
+- 优先级允许更高，因为这是退出 / 保存路径，不是 runtime 热路径
+
+- [ ] **Step 3: 确认 World.dispose / Game 退出链路会调用它**
+
+检查：
+- `src/world/World.js`
+- `src/core/Game.js`
+
+要求：
+- 正常退出时尽量多落盘
+- 但不要重新把 runtime 帧路径绑回同步写盘
+
+- [ ] **Step 4: 重新运行测试**
+
+打开：
+```text
+http://127.0.0.1:8080/src/tests/index.html
+```
+
+Expected:
+- 新增退出路径测试通过
+- 原有 runtime persistence 相关测试不回归
+
+## Task 6: 调整观测，避免 perf debug 本身放大 unload 成本
+
+**Files:**
+- Modify: `src/world/WorldRuntime.js`
+- Modify: `src/utils/ChunkPerfMonitor.js`
+- Potentially Modify: `src/core/Game.js`
+
+- [ ] **Step 1: 先阅读当前 flush perf 统计逻辑**
+
+检查：
+- `src/world/WorldRuntime.js`
+- `src/utils/ChunkPerfMonitor.js`
+- `src/core/Game.js`
+
+确认哪些统计会对大 `blockData` 做：
+- `Object.keys`
+- `JSON.stringify`
+
+- [ ] **Step 2: 对 unload/background flush 的大对象统计降级**
+
+要求：
+- debug 打开时，`flush-before-unload` / background flush 不再默认 `JSON.stringify` 大对象
+- 保留必要的 `blockCount`、source、queue size 即可
+
+- [ ] **Step 3: 增加 load / unload 的区分字段**
+
+要求：
+- 后续日志里能明确区分：
+  - `chunk load`
+  - `unload enqueue`
+  - `background flush`
+  - `shutdown flush`
+
+- [ ] **Step 4: 运行 lint**
+
+Run:
+```bash
+npm run lint
+```
+
+Expected:
+- 无新增 lint error
+
+## Task 7: 跑运行期验证，确认主瓶颈已从 unload 热路径移走
+
+**Files:**
+- Modify: 无（验证任务）
+
+- [ ] **Step 1: 启动项目**
+
+Run:
+```bash
+npm run start
+```
+
+- [ ] **Step 2: 打开 debug 并执行高速跑图场景**
+
+在浏览器中：
+- 进入游戏
+- 开启 `CHUNK_PERF_DEBUG`
+- 开启 `StreamingPerf`
+- 高速直线跑图，持续触发 chunk load/unload
+
+- [ ] **Step 3: 记录关键指标**
+
+重点观察：
+- 是否还出现 `world-runtime.flush-before-unload` 的超长日志
+- 是否仍出现 `blockDataSource: live-chunk`
+- unload 队列长度是否可控
+- background flush 是否分批稳定消化
+
+- [ ] **Step 4: 验证目标是否达成**
+
+达标标准：
+- unload 当帧不再触发 `live-chunk` 整块序列化
+- 高速跑图时体感 jank 明显下降
+- `chunk.accept-scattered-blocks` 等 load 路径指标不回退
+- 队列不会失控增长
+
+## 备注
+
+- 当前仓库明确要求：**不能自动提交代码**。执行本计划时不要自动 commit，除非用户明确要求。
+- 当前目标是 runtime 流畅度优先，所以允许后台待写队列中的最近变更在崩溃场景下丢失。
+- 不要把 unload 优化重新做成“换个地方同步写盘”；凡是会把 `chunk unload` 再次和即时持久化绑定起来的实现，都偏离本计划目标。

- loadFromRecord 不再同步完成 build + finalize，改为只入装配队列交由调度器切片执行
- finalizeNonDeferredPhase 在 runtime-streaming 下延迟光源注册与 AO 刷新到 deferred finalize
- ChunkAssemblyScheduler 限制同轮只处理初始队列任务，防止新入队后续阶段连击
- onChunkFinalized 支持 deferAORefresh 选项，避免 finalized 当帧立即刷新 AO
- 新增测试覆盖装配队列切片行为与 deferred finalize 延迟逻辑

+# BlockData Render Cache Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** 为 `ChunkRecord` 增加非权威 `renderCache` 快速上屏层，消灭 `load-from-record` 主线程重复扫描 `blockData` 并生成 `meshData` 的热路径。
+
+**Architecture:** 在 `ChunkRecord` 中内嵌 `renderCache`，由 worker 在预生成与重建路径中产出，runtime 纯加载优先消费 cache。`blockData` 继续作为唯一权威世界真相；`renderCache` 仅服务快速上屏，缺失或失效时回退到 worker 重建并后台补写。
+
+**Tech Stack:** JavaScript ES Modules、Three.js、Web Worker、IndexedDB(WorldStore/PersistenceWorker)、现有 Chunk/WorldRuntime/WorldGenerationService 渲染链路。
+
+---
+
+## 文件边界
+
+**新增文件：**
+- `src/world/RenderCache.js`：`renderCache` 结构校验、版本常量、source hash 计算、失效判定
+
+**修改文件：**
+- `src/world/Chunk.js`：`loadFromRecord()` 优先消费 `renderCache`，主线程 `_buildMeshFromExistingBlockData()` 降级为 fallback
+- `src/world/ChunkGenerator.js`：需要时为 fallback worker build path 提供统一入口
+- `src/world/WorldGenerationService.js`：预生成阶段写入 `renderCache`
+- `src/workers/WorldWorker.js`：region/chunk 生成结果附带 `renderCache`
+- `src/world/ChunkConsolidation.js` 或相关 consolidation 回包消费文件：合并完成后同步更新 `renderCache`
+- `src/world/WorldRuntime.js`：后台补写 `renderCache` 时复用现有 WorldStore 写回路径
+- `src/world/WorldStore.js`：必要时补充 `renderCache` 相关读写注释/类型约束
+- `src/tests/test-chunk.js`
+- `src/tests/test-world-generation-cross-region.js` 或 `src/tests/test-world.js`
+- `src/tests/test-world-runtime.js`
+
+**参考文件：**
+- `src/world/Chunk.js`
+- `src/world/WorldRuntime.js`
+- `src/world/WorldGenerationService.js`
+- `docs/superpowers/specs/2026-04-30-blockdata-render-cache-design.md`
+
+## Task 1: 定义 renderCache 结构与失效规则
+
+**Files:**
+- Create: `src/world/RenderCache.js`
+- Test: `src/tests/test-chunk.js`
+
+- [ ] **Step 1: 写失败测试，覆盖 renderCache 结构判定与失效规则**
+
+测试点：
+- `version` 不匹配应失效
+- `sourceHash` 不匹配应失效
+- 缺少 `meshData`/`visibleKeys`/`lightSources` 应失效
+- 结构完整时应判定有效
+
+- [ ] **Step 2: 运行目标测试，确认当前失败**
+
+Run: `npm run start` 后打开 `http://localhost:8080/src/tests/index.html`
+Expected: render cache 相关测试失败，因为模块与函数尚不存在
+
+- [ ] **Step 3: 实现 `RenderCache.js` 最小能力**
+
+实现内容：
+- `CURRENT_RENDER_CACHE_VERSION`
+- `CURRENT_RENDER_CACHE_GENERATOR_VERSION`
+- `computeRenderCacheSourceHash(chunkRecord)`
+- `isRenderCacheStructurallyValid(renderCache)`
+- `isRenderCacheUsable(chunkRecord)`
+
+约束：
+- 先用稳定、简单的 hash
+- 不追求极致性能，先保证一致性
+
+- [ ] **Step 4: 重新运行测试，确认通过**
+
+Run: 浏览器测试页点击“运行所有测试”
+Expected: render cache 结构与失效判定测试通过
+
+## Task 2: 给 Chunk 纯加载路径接入 renderCache 主路径
+
+**Files:**
+- Modify: `src/world/Chunk.js`
+- Test: `src/tests/test-chunk.js`
+
+- [ ] **Step 1: 写失败测试，验证 `loadFromRecord()` 优先消费 renderCache**
+
+测试点：
+- 当 `chunkRecord.renderCache` 有效时，不调用 `_buildMeshFromExistingBlockData()`
+- 直接使用 `renderCache.meshData` 构建 mesh
+- 直接恢复 `visibleKeys`
+- 直接恢复 `lightSourceCoords`
+
+- [ ] **Step 2: 运行目标测试，确认当前失败**
+
+Expected: 现有实现仍会走 `_buildMeshFromExistingBlockData()`
+
+- [ ] **Step 3: 最小实现 Chunk 的 renderCache 应用逻辑**
+
+实现内容：
+- 在 `loadFromRecord()` 中加入 `renderCache` 判定
+- 新增内部方法，例如：
+  - `_applyRenderCache(renderCache)`
+  - `_restoreVisibleKeysFromRenderCache(renderCache)`
+  - `_restoreLightSourcesFromRenderCache(renderCache)`
+- 将 `_buildMeshFromExistingBlockData()` 降级为 fallback
+
+- [ ] **Step 4: 运行测试，确认主路径改为消费 cache**
+
+Expected: 测试通过，主线程不再在有效 cache 情况下重建 meshData
+
+## Task 3: 增加 worker fallback 重建路径
+
+**Files:**
+- Modify: `src/world/Chunk.js`
+- Modify: `src/workers/WorldWorker.js`
+- Modify: `src/world/ChunkGenerator.js`
+- Test: `src/tests/test-chunk.js`
+
+- [ ] **Step 1: 写失败测试，覆盖 cache 缺失/失效时的 worker fallback**
+
+测试点：
+- cache 缺失时，不走主线程 `_buildMeshFromExistingBlockData()` 主路径
+- 发起 worker render cache build 请求
+- worker 返回后应用 render cache 并完成上屏
+
+- [ ] **Step 2: 运行测试，确认当前失败**
+
+- [ ] **Step 3: 为 worker 增加“从 chunkRecord/blockData 构建 renderCache”的消息处理**
+
+实现内容：
+- 在 `WorldWorker` 中新增构建 render cache 的 action
+- 复用现有 mesh/AO 构建逻辑，直接产出 cache 结构
+- 保持结果格式与 `Chunk.buildMeshes()` 兼容
+
+- [ ] **Step 4: 在 Chunk 侧接入 fallback 结果消费**
+
+实现内容：
+- `loadFromRecord()` 在 cache 失效时等待 worker 结果
+- 成功后调用 `_applyRenderCache()`
+- 失败时才允许最终兜底走 `_buildMeshFromExistingBlockData()`
+
+- [ ] **Step 5: 运行测试，确认 fallback 链路可用**
+
+Expected: cache 缺失时仍可加载 chunk，但主路径已切到 worker 而非主线程
+
+## Task 4: 在预生成阶段写入 renderCache
+
+**Files:**
+- Modify: `src/workers/WorldWorker.js`
+- Modify: `src/world/WorldGenerationService.js`
+- Test: `src/tests/test-world-generation-cross-region.js`
+
+- [ ] **Step 1: 写失败测试，验证 region 预生成结果包含 renderCache**
+
+测试点：
+- `RegionRecord.chunks[chunkKey]` 中带有 `renderCache`
+- `renderCache.sourceHash` 与 `blockData` 对应
+
+- [ ] **Step 2: 运行测试，确认当前失败**
+
+- [ ] **Step 3: 在预生成 worker 结果中为每个 chunk 补齐 renderCache**
+
+实现内容：
+- region generation 产出 chunk 时同步生成 render cache
+- `WorldGenerationService` 写入 WorldStore 时保持该字段
+
+- [ ] **Step 4: 运行测试，确认新档预生成路径具备 cache**
+
+Expected: 新生成的 region record 已包含 render cache
+
+## Task 5: consolidation 完成后同步刷新 renderCache
+
+**Files:**
+- Modify: `src/world/Chunk.js`
+- Modify: `src/world/ChunkConsolidation.js` 或实际 consolidation 回包消费文件
+- Modify: `src/world/WorldRuntime.js`
+- Test: `src/tests/test-world-runtime.js`
+
+- [ ] **Step 1: 写失败测试，验证 runtime 修改后的 chunk 会刷新 renderCache**
+
+测试点：
+- 玩家修改后触发 consolidation
+- consolidation 回包后 chunk 拿到新的 render cache
+- 后台写回时最新 cache 跟随 chunkRecord 一起进入 WorldStore
+
+- [ ] **Step 2: 运行测试，确认当前失败**
+
+- [ ] **Step 3: 在 consolidation 成功链路里生成并挂接新 renderCache**
+
+实现内容：
+- worker consolidation 回包附带 render cache
+- chunk 应用最新 cache
+- WorldRuntime 写回时把新 cache 一并写入 chunkRecord
+
+- [ ] **Step 4: 运行测试，确认修改后的 chunk reload 不再回退到旧主线程重建路径**
+
+Expected: 交互修改后的 chunk 卸载再加载仍优先消费 cache
+
+## Task 6: 增加性能回归观测点
+
+**Files:**
+- Modify: `src/world/Chunk.js`
+- Modify: `src/world/World.js`
+- Test: `src/tests/test-world.js`
+
+- [ ] **Step 1: 写失败测试，验证 `load-from-record` 日志区分 cache-hit / cache-miss / fallback-worker**
+
+- [ ] **Step 2: 运行测试，确认当前失败**
+
+- [ ] **Step 3: 增加最小观测字段**
+
+建议字段：
+- `renderCacheStatus: hit | miss | stale | fallback-worker | fallback-main-thread`
+- `renderCacheMeshGroups`
+- `renderCacheVisibleKeys`
+
+- [ ] **Step 4: 运行测试，确认日志与快照可用于前后对比**
+
+Expected: 后续可以直接比较优化前后 `chunk.load-from-record` 是否仍含 `convertMeshDataMs`
+
+## Task 7: 手工验证
+
+**Files:**
+- Modify: 无新增代码，验证已有改动
+
+- [ ] **Step 1: 启动开发服务器**
+
+Run: `npm run start`
+Expected: 本地静态服务器启动在 `http://localhost:8080`
+
+- [ ] **Step 2: 运行浏览器测试**
+
+访问: `http://localhost:8080/src/tests/index.html`
+Expected: 相关测试全部通过
+
+- [ ] **Step 3: 手工观察 runtime streaming 日志**
+
+关注：
+- `chunk.load-from-record`
+- `StreamingPerf`
+- `mutationQueueBlocks`
+- `WorkerRpcClient.js:15 message handler`
+
+Expected:
+- cache hit 情况下不再出现主线程 `convertMeshDataMs` 热点
+- `chunk.load-from-record` 总耗时下降
+- 新档纯加载路径上屏更快
+
+## 备注
+
+1. 本计划第一版不拆独立 `render_cache` store
+2. 本计划第一版不处理 region 整包回主线程问题
+3. 本计划第一版只把 `_buildMeshFromExistingBlockData()` 从主路径挪走，并保留最终兜底
+4. 根据仓库约束，本轮不自动提交；如需提交，等你明确下指令再做

+# BlockData Render Cache Design
+
+日期：2026-04-30  
+分支：`gen-big-map-first`  
+代码基线：`fc0eba235a8454507c6e87548c7a746ce7324366`
+
+## 背景
+
+当前 `worldStore` 重构已经完成了权威数据源迁移、运行时内存与 IndexedDB IO 解耦、Region 级预生成和特殊实体的 shadow sync 隔离。现阶段运行时掉帧主因已经不再是“地图生成还在主线程”，而是 chunk 从 `WorldStore` 读出后，主线程仍要重新扫描 `blockData`，构建上屏所需的 `meshData / visibleKeys / lightSources`。
+
+现有日志显示：
+
+- `chunk.load-from-record`: `5.2ms ~ 12.5ms`
+- `convertMeshDataMs`: `2.6ms ~ 9.9ms`
+- `chunk.build-meshes-global`: `1.8ms ~ 3.3ms`
+- `StreamingPerf.mutationQueueBlocks`: 峰值可达 `9k ~ 16k`
+- `WorkerRpcClient.js:15 message handler`: 可见 `305ms / 448ms` 级别的跨线程大对象传输尖峰
+
+说明问题已经转移到：
+
+1. runtime 主线程重复解释 `blockData`
+2. region 级大对象在主线程和 worker 之间搬运
+3. 上屏实例提交吞吐不足
+
+本设计专注解决第 1 点，并为第 2 点留下兼容接口。
+
+## 目标
+
+1. 消灭 `load-from-record` 主线程里对 `blockData` 的重复扫描和 `meshData` 重建
+2. 保持 `blockData` 作为唯一权威世界真相，不让缓存层影响数据正确性
+3. 允许缓存缺失、过期、版本升级时安全回退到 worker 重建
+4. 尽量复用现有 `WorldStore / RegionRecord / ChunkRecord / global instanced manager` 架构，不做第一版过度拆分
+
+## 非目标
+
+1. 第一版不解决 `RegionRecord` 整包回主线程的问题
+2. 第一版不重写 `GlobalInstancedMeshManager` 的 mutation queue 机制
+3. 第一版不改变 `runtimeEntities`、`ShadowSyncWorker` 的职责划分
+4. 第一版不尝试把所有 AO 运行时逻辑都缓存化
+
+## 方案对比
+
+### 方案 A：仅把 `load-from-record` 的 mesh/AO 构建挪到 worker，即时生成，不持久化
+
+做法：
+- `Chunk.loadFromRecord()` 不在主线程 `_buildMeshFromExistingBlockData()`
+- 改为把 `chunkRecord.blockData` 发给 worker，worker 返回 `meshData`
+- 主线程只负责 `buildMeshes()`
+
+优点：
+- 代码改动相对集中
+- 不增加存储体积
+- 先把主线程 CPU 热点搬走
+
+缺点：
+- 每次 chunk 纯加载仍然要重新计算一次 mesh/AO
+- 首次上屏延迟仍然受 worker 计算影响
+- 无法把“预生成阶段已经算过的结果”复用到 runtime
+
+结论：
+- 适合作为兜底 fallback，不适合作为主方案
+
+### 方案 B：在 `ChunkRecord` 中内嵌 `renderCache`，预生成和 consolidation 时生成，runtime 直接消费
+
+做法：
+- 在每个 chunk 权威记录旁边保存一份渲染缓存 `renderCache`
+- `renderCache` 包含直接上屏所需的 `meshData / visibleKeys / lightSources`
+- runtime 纯加载优先消费 `renderCache`
+- 若 cache 缺失或过期，再回退到 worker 重建并补写
+
+优点：
+- 完全符合“用空间换 runtime 时间”的目标
+- 能复用预生成阶段和 consolidation 阶段已经做过的计算
+- `load-from-record` 主线程路径最短
+
+缺点：
+- 存储体积增大
+- 缓存失效管理变复杂
+- 如果继续按 region 整包回主线程，消息体可能更大
+
+结论：
+- 这是最符合当前架构目标的主方案
+
+### 方案 C：把 `renderCache` 独立成单独 store，仅在 runtime 读取
+
+做法：
+- 权威数据继续存 `world_regions`
+- 新增独立 `render_cache` store，按 chunk 或 region 存缓存
+- runtime 先取 cache，再按需取权威 chunk record
+
+优点：
+- 权威数据和缓存数据边界最干净
+- 可以独立清除缓存、独立升级版本
+- 后续做 chunk 级直接读取时更灵活
+
+缺点：
+- 第一版工程复杂度更高
+- 读路径变成双 store 协调
+- 容易在第一版就引入过多同步规则
+
+结论：
+- 更适合作为第二阶段演进，不适合第一版直接上
+
+## 结论与推荐
+
+推荐先落地方案 B：在 `ChunkRecord` 中内嵌 `renderCache`，并明确它是非权威、可丢弃、可重建的快速上屏缓存层。
+
+这条路线能在最少架构扰动下，直接消灭当前 `load-from-record` 的主线程热点。
+
+## 数据模型
+
+### 当前 ChunkRecord
+
+```js
+{
+  blockData,
+  staticEntities,
+  runtimeSeedData,
+  runtimeEntities
+}
+```
+
+### 目标 ChunkRecord
+
+```js
+{
+  blockData,
+  staticEntities,
+  runtimeSeedData,
+  runtimeEntities,
+  renderCache: {
+    version: 1,
+    sourceHash: "string",
+    meshData: [
+      {
+        type,
+        count,
+        matrices,
+        aoLow,
+        aoHigh,
+        orientation,
+        instanceIndexMap
+      }
+    ],
+    visibleKeys: [123, 456, 789],
+    lightSources: [123, 456],
+    generatedAt: 1714450000000,
+    generatorVersion: "render-cache-v1"
+  }
+}
+```
+
+## 字段语义
+
+### `version`
+
+缓存结构版本号。用于未来 cache 格式升级时快速失效。
+
+### `sourceHash`
+
+由权威层内容计算得到的签名，至少覆盖：
+
+- `blockData`
+- 必要时覆盖影响 mesh 的 `runtimeSeedData.structureCenters`
+
+第一版可以先实现稳定但不极致高效的 hash，例如：
+- 先对 blockData key 排序
+- 再对 `{ type, orientation }` 序列化后生成字符串 hash
+
+要求不是密码学安全，而是稳定、一致、可检测是否过期。
+
+### `meshData`
+
+直接兼容现有 `buildMeshes()` / `replaceChunkVisibleBlocks()` 输入格式。第一版目标不是重新设计渲染提交格式，而是直接绕过主线程 `_convertScatteredBlocksToMeshData()`。
+
+### `visibleKeys`
+
+直接恢复 chunk 的可见块索引，避免 runtime 再从 `meshData` 或 `blockData` 反推。
+
+### `lightSources`
+
+直接恢复该 chunk 内的光源编码坐标，避免 finalize 或 deferred finalize 再遍历 `blockData`。
+
+## 核心原则
+
+1. `blockData` 永远权威
+2. `renderCache` 永远非权威
+3. 主线程只消费 cache，不负责修 cache
+4. cache 缺失或过期时，由 worker 重建
+5. cache 重建失败不影响世界正确性，只影响上屏延迟
+
+## 生成链路
+
+### 链路 1：预生成阶段
+
+由 `WorldWorker.generateRegion` 产出每个 chunk 的：
+
+- `blockData`
+- `staticEntities`
+- `runtimeSeedData`
+- `renderCache`
+
+再一起写入 `RegionRecord.chunks[chunkKey]`。
+
+这样新档进入 runtime streaming 时，第一次加载就能直接消费 `renderCache`。
+
+### 链路 2：运行时 consolidation 完成后
+
+当前 consolidation 已经在 worker 重算可见面和 AO。此时应顺手产出新的 `renderCache`，并把它与最新 `blockData` 一起回写 `WorldStore`。
+
+这样经过交互修改后的 chunk，在下一次卸载/重载时仍然能直接走快速上屏路径。
+
+### 链路 3：缓存缺失或失效时
+
+如果 `renderCache`：
+
+- 不存在
+- `version` 不匹配
+- `sourceHash` 不匹配
+- 结构校验失败
+
+则：
+
+1. runtime 发起 worker 重建请求
+2. 当前 chunk 进入“等待渲染缓存”状态
+3. worker 返回 `renderCache`
+4. 主线程只负责挂载 mesh
+5. 后台把新 cache 补写回 `WorldStore`
+
+## 运行时加载链路
+
+### 当前路径
+
+```text
+WorldStore chunkRecord
+-> Chunk.loadFromRecord()
+-> _injectBlockData()
+-> _buildMeshFromExistingBlockData()
+-> 遍历 blockData
+-> _convertScatteredBlocksToMeshData()
+-> buildMeshes()
+```
+
+### 目标路径
+
+```text
+WorldStore chunkRecord
+-> Chunk.loadFromRecord()
+-> _injectBlockData()   // 保留，作为运行时逻辑视图
+-> validateRenderCache()
+-> applyRenderCache()
+-> buildMeshes(renderCache.meshData)
+```
+
+### fallback 路径
+
+```text
+WorldStore chunkRecord
+-> renderCache invalid/missing
+-> worker build render cache
+-> applyRenderCache()
+-> background patch WorldStore
+```
+
+## 主线程职责调整
+
+### 保留
+
+1. 注入 `blockData` 到 runtime 视图
+2. 恢复 `runtimeEntities`/shadow store
+3. 最终 mesh 挂载
+4. deferred finalize
+
+### 删除或降级为 fallback
+
+1. `_buildMeshFromExistingBlockData()` 不再是主路径
+2. `_convertScatteredBlocksToMeshData()` 不再在 `load-from-record` 期间主线程执行
+3. `visibleKeys` 不再由主线程扫描 blockData 重建
+
+## 失效规则
+
+以下任一命中时，`renderCache` 失效：
+
+1. `renderCache.version !== CURRENT_RENDER_CACHE_VERSION`
+2. `renderCache.generatorVersion !== CURRENT_RENDER_CACHE_GENERATOR_VERSION`
+3. `renderCache.sourceHash !== computeRenderCacheSourceHash(chunkRecord)`
+4. `meshData` 缺字段或结构非法
+
+第一版不追求局部修复，直接整块 chunk cache 重建。
+
+## 存储位置
+
+第一版建议直接内嵌到 `RegionRecord.chunks[chunkKey]`：
+
+```js
+region.chunks[chunkKey] = {
+  blockData,
+  staticEntities,
+  runtimeSeedData,
+  runtimeEntities,
+  renderCache
+};
+```
+
+原因：
+
+1. 改动面最小
+2. 不需要额外 store 协议
+3. 与当前 `ChunkRecord` 读取方式兼容
+
+已知代价：
+- region record 变大
+- 主线程和 worker 之间整包消息更重
+
+但这属于下一阶段要继续解决的问题，不应该阻塞第一版先把 `load-from-record` 热点拿掉。
+
+## 第二阶段演进方向
+
+第一版稳定后，可以继续评估：
+
+1. `renderCache` 独立 store
+2. `PersistenceWorker` 直接提供 chunk 级投影读取
+3. `meshData` 是否改成更适合 `GlobalInstancedMeshManager` 直接消费的紧凑格式
+4. `visibleKeys` 是否需要改为 typed array / transferable 以降低 message 成本
+
+## 风险与防护
+
+### 风险 1：存储体积膨胀
+
+防护：
+- 接受这是“用空间换 runtime 时间”的设计取舍
+- 第一版只缓存确实能消灭主线程热点的字段，不扩大范围
+
+### 风险 2：缓存与权威数据不一致
+
+防护：
+- 严格坚持 `blockData` 权威、`renderCache` 非权威
+- 统一用 `version + sourceHash` 判失效
+- 不做主线程修补 cache
+
+### 风险 3：region 级整包传输变更重
+
+防护：
+- 先落地 render cache 层，验证 `load-from-record` 热点是否消失
+- 再推进 chunk 级投影读取，分阶段解决
+
+## 测试策略
+
+1. 单元测试
+- `renderCache` 结构校验
+- `sourceHash` 稳定性
+- 失效判定逻辑
+- cache 缺失时 fallback worker 重建
+
+2. 集成测试
+- 新档预生成后，runtime 纯加载直接消费 cache
+- 玩家修改 chunk 后，consolidation 重建 cache 并持久化
+- chunk unload/reload 后，不再走主线程 `convertMeshData`
+
+3. 性能验证
+- 对比优化前后 `chunk.load-from-record`
+- 目标是把 `convertMeshDataMs` 从主线程热点中消灭
+- 验证 `StreamingPerf` 下 mutation queue 是否下降
+
+## 分阶段落地建议
+
+### Phase 1
+
+1. 定义 `renderCache` 数据结构和版本号
+2. 在 `Chunk.loadFromRecord()` 中增加 `renderCache` 优先路径
+3. 把 `_buildMeshFromExistingBlockData()` 降级为 fallback
+4. 增加 worker 侧“从权威 chunkRecord 构建 renderCache”的能力
+
+### Phase 2
+
+1. 在预生成阶段写入 `renderCache`
+2. 在 consolidation 回包中同步更新 `renderCache`
+3. 增加持久化回写链路
+
+### Phase 3
+
+1. 评估是否拆出独立 cache store
+2. 推进 chunk 级读取投影，减少 region 整包回主线程
+
+## 最终结论
+
+`renderCache` 不是一层可有可无的附加缓存，而是当前 `worldStore` 架构继续向“runtime 只做上屏、不做重计算”推进时必须补齐的一层。
+
+它的职责边界应该非常明确：
+
+- 不代表世界真相
+- 不参与逻辑正确性判断
+- 只负责 chunk 快速上屏
+- 丢了可重建
+- 过期可失效
+
+第一版推荐以内嵌 `ChunkRecord.renderCache` 的方式落地，先直接消灭 `load-from-record` 期间那段 `3ms ~ 10ms / chunk` 的主线程重建成本，再继续处理 region 级大对象传输和 mutation queue 吞吐问题。

Subject: [PATCH 49/66] docs: revise blockdata render cache spec and plan to v2

- Replace sourceHash with O(1) contentRevision for cache invalidation
- Add data-layer fidelity tasks (WorldStore/WorldRuntime/PersistenceWorker)
before runtime cache consumption
- Define renderCache serialization spec for TypedArray persistence
- Add contentRevision monotonicity constraints across flush/unload/patch
- Mark worker fallback as P1 optional, P0 uses main-thread stable fallback
- Handle cross-region overflow pollution (dirty-by-overflow -> miss)
- Require Chunk instance to explicitly hold contentRevision/renderCache

-**Goal:** 为 `ChunkRecord` 增加非权威 `renderCache` 快速上屏层，消灭 `load-from-record` 主线程重复扫描 `blockData` 并生成 `meshData` 的热路径。
+**Goal:** 为 `ChunkRecord` 增加非权威 `renderCache` 快速上屏层，并让 runtime 纯加载优先消费 cache，避免主线程重复遍历 `blockData` 构建 `meshData`。
 
-**Architecture:** 在 `ChunkRecord` 中内嵌 `renderCache`，由 worker 在预生成与重建路径中产出，runtime 纯加载优先消费 cache。`blockData` 继续作为唯一权威世界真相；`renderCache` 仅服务快速上屏，缺失或失效时回退到 worker 重建并后台补写。
+**Architecture:** 使用内嵌于 `ChunkRecord` 的 `renderCache + contentRevision` 方案。先打通 `WorldStore / WorldRuntime / PersistenceWorker` 对新字段的读写保真，再接入 pregen / consolidation 的 cache 生产，最后切换 `Chunk` 纯加载主路径到 cache-first。P0 的 miss/stale 保留主线程稳定兜底；worker fallback 下放到 P1 可选增强。

 # BlockData Render Cache Design
 
-日期：2026-04-30  
+日期：2026-05-01  
 分支：`gen-big-map-first`  
-代码基线：`fc0eba235a8454507c6e87548c7a746ce7324366`
+定位：P0 快速上屏缓存层设计修订版
 
 ## 背景
 
-当前 `worldStore` 重构已经完成了权威数据源迁移、运行时内存与 IndexedDB IO 解耦、Region 级预生成和特殊实体的 shadow sync 隔离。现阶段运行时掉帧主因已经不再是“地图生成还在主线程”，而是 chunk 从 `WorldStore` 读出后，主线程仍要重新扫描 `blockData`，构建上屏所需的 `meshData / visibleKeys / lightSources`。
+`WorldStore` 重构后，chunk 纯加载已经不再需要重新生成地形，但 runtime 仍然会在主线程重新解释 `blockData`，再构建首帧上屏所需的 `meshData / visibleKeys`。当前真实热点不在“是否从存档读到 blockData”，而在“读到之后仍然要重新遍历并转换一次”。
 
-现有日志显示：
+结合当前代码，问题已经比较明确：
 
-- `chunk.load-from-record`: `5.2ms ~ 12.5ms`
-- `convertMeshDataMs`: `2.6ms ~ 9.9ms`
-- `chunk.build-meshes-global`: `1.8ms ~ 3.3ms`
-- `StreamingPerf.mutationQueueBlocks`: 峰值可达 `9k ~ 16k`
-- `WorkerRpcClient.js:15 message handler`: 可见 `305ms / 448ms` 级别的跨线程大对象传输尖峰
+1. `Chunk.loadFromRecord()` 注入 `blockData` 后，runtime build 阶段仍会进入主线程 `_buildMeshFromExistingBlockData()`。
+2. `WorldWorker` 已经具备产出 `meshData / visibleKeys` 的能力，但这些结果没有作为稳定缓存进入 `ChunkRecord`。
+3. `WorldRuntime / WorldStore` 当前只投影 `blockData/staticEntities/runtimeSeedData/runtimeEntities`，任何新加的 `renderCache` 字段都会被读写链路吞掉。
+4. region 预生成完成后还会在主线程合并 cross-region overflow，这一步会让“预先算好的 mesh cache”立即过期。
 
-说明问题已经转移到：
+因此，P0 的核心不是“再设计一种新渲染格式”，而是：
 
-1. runtime 主线程重复解释 `blockData`
-2. region 级大对象在主线程和 worker 之间搬运
-3. 上屏实例提交吞吐不足
-
-本设计专注解决第 1 点，并为第 2 点留下兼容接口。
+- 给 `ChunkRecord` 增加非权威 `renderCache`
+- 让 runtime 纯加载优先消费它
+- 让缓存失效规则是 O(1) 判定
+- 让现有 pregen / consolidation / flush 链路不会把缓存写丢或写脏
 
 ## 目标
 
-1. 消灭 `load-from-record` 主线程里对 `blockData` 的重复扫描和 `meshData` 重建
-2. 保持 `blockData` 作为唯一权威世界真相，不让缓存层影响数据正确性
-3. 允许缓存缺失、过期、版本升级时安全回退到 worker 重建
-4. 尽量复用现有 `WorldStore / RegionRecord / ChunkRecord / global instanced manager` 架构，不做第一版过度拆分
+1. 消灭 `load-from-record` 主线程里对 `blockData` 的重复扫描和 `meshData` 重建。
+2. 保持 `blockData` 为唯一权威世界真相，`renderCache` 只是快速上屏副本。
+3. 缓存失效判定必须是 O(1)，不能为了校验 cache 再次全量遍历 `blockData`。
+4. 缓存缺失、过期、版本升级、overflow 污染时都能安全回退到稳定路径。
+5. 第一版尽量复用现有 `WorldWorker` 输出与 `buildMeshes()` 输入，不重写渲染提交格式。
 
 ## 非目标
 
-1. 第一版不解决 `RegionRecord` 整包回主线程的问题
-2. 第一版不重写 `GlobalInstancedMeshManager` 的 mutation queue 机制
-3. 第一版不改变 `runtimeEntities`、`ShadowSyncWorker` 的职责划分
-4. 第一版不尝试把所有 AO 运行时逻辑都缓存化
+1. 第一版不解决 `RegionRecord` 整包回主线程的消息体偏大问题。
+2. 第一版不重写 `GlobalInstancedMeshManager` 的 mutation queue。
+3. 第一版不把所有 chunk 派生状态都缓存化。
+4. 第一版不把 `lightSourceCoords` 恢复链路也一起做成缓存优先。
+5. 第一版不拆独立 `render_cache` store。
+6. 第一版不把 worker fallback render cache build 作为必需主链路。
 
-## 方案对比
+## 当前代码现实
+
+### 纯加载热路径
+
+当前 runtime 纯加载真实路径是：
+
+```text
+WorldRuntime.ensureChunkData()
+-> Chunk.loadFromRecord()
+-> loadState = record-ready
+-> Chunk.assembleRuntimeBuildPhase()
+-> _buildMeshFromExistingBlockData()
+-> 遍历 this.blockData
+-> _convertScatteredBlocksToMeshData()
+-> buildMeshes()
+```
+
+说明：
+
+- 设计目标必须覆盖 `assembleRuntimeBuildPhase()`，不能只改 `loadFromRecord()`。
+- 只要 `_buildMeshFromExistingBlockData()` 仍是 `record-ready` 主路径，就没有真正消灭卡顿。
+
+### worker 侧现有能力
+
+`WorldWorker` 已经能输出：
+
+- `meshData`
+- `visibleKeys`
+- `solidBlocks`
+- `structureCenters`
+- `scatteredBlocks`
 
-### 方案 A：仅把 `load-from-record` 的 mesh/AO 构建挪到 worker，即时生成，不持久化
+这意味着 P0 不应该引入第二套 mesh 构建逻辑，而应直接复用现有 worker 结果去组装 `renderCache`。
 
-做法：
-- `Chunk.loadFromRecord()` 不在主线程 `_buildMeshFromExistingBlockData()`
-- 改为把 `chunkRecord.blockData` 发给 worker，worker 返回 `meshData`
-- 主线程只负责 `buildMeshes()`
+### 读写链路现状
+
+当前以下路径都会重建或截断 `chunkRecord`：
+
+- `WorldRuntime.ensureChunkData()`
+- `WorldStore._extractChunkRecord()`
+- `WorldRuntime.flushChunk()`
+- `WorldRuntime.flushAllDirty()`
+- `PersistenceWorker.applyRegionPatch()`
+
+如果不先改这些地方，新增的 `renderCache` 字段会出现以下问题：
+
+1. 读不出来
+2. 写回时被覆盖丢失
+3. pending unload patch 时被旧数据回滚
+
+所以“先接入 Chunk 消费 renderCache，再补数据层”这个顺序是错的。
+
+## 方案对比
+
+### 方案 A：load miss 时只把转换挪到 worker，不持久化
 
 优点：
-- 代码改动相对集中
+
+- 改动集中
 - 不增加存储体积
-- 先把主线程 CPU 热点搬走
 
 缺点：
-- 每次 chunk 纯加载仍然要重新计算一次 mesh/AO
-- 首次上屏延迟仍然受 worker 计算影响
-- 无法把“预生成阶段已经算过的结果”复用到 runtime
+
+- 每次纯加载仍要重新算一次
+- 无法复用 pregen / consolidation 已有结果
+- 只是把卡顿从主线程换到 worker 等待，不是快速上屏
 
 结论：
-- 适合作为兜底 fallback，不适合作为主方案
 
-### 方案 B：在 `ChunkRecord` 中内嵌 `renderCache`，预生成和 consolidation 时生成，runtime 直接消费
+- 适合作为 fallback，不适合作为 P0 主方案
 
-做法：
-- 在每个 chunk 权威记录旁边保存一份渲染缓存 `renderCache`
-- `renderCache` 包含直接上屏所需的 `meshData / visibleKeys / lightSources`
-- runtime 纯加载优先消费 `renderCache`
-- 若 cache 缺失或过期，再回退到 worker 重建并补写
+### 方案 B：在 `ChunkRecord` 中内嵌 `renderCache`
 
 优点：
-- 完全符合“用空间换 runtime 时间”的目标
-- 能复用预生成阶段和 consolidation 阶段已经做过的计算
-- `load-from-record` 主线程路径最短
+
+- 最符合“空间换时间”
+- 能直接复用 worker 已有输出
+- 对现有 `Chunk.buildMeshes()` 侵入最小
 
 缺点：
-- 存储体积增大
-- 缓存失效管理变复杂
-- 如果继续按 region 整包回主线程，消息体可能更大
+
+- `RegionRecord` 体积增大
+- 需要明确失效与保留规则
+- 需要修正 `WorldRuntime/WorldStore` 投影链路
 
 结论：
-- 这是最符合当前架构目标的主方案
 
-### 方案 C：把 `renderCache` 独立成单独 store，仅在 runtime 读取
+- 这是 P0 正确主方案
 
-做法：
-- 权威数据继续存 `world_regions`
-- 新增独立 `render_cache` store，按 chunk 或 region 存缓存
-- runtime 先取 cache，再按需取权威 chunk record
+### 方案 C：独立 `render_cache` store
 
 优点：
-- 权威数据和缓存数据边界最干净
-- 可以独立清除缓存、独立升级版本
-- 后续做 chunk 级直接读取时更灵活
+
+- 权威数据与缓存边界最干净
+- 更利于未来做 chunk 级独立读取
 
 缺点：
-- 第一版工程复杂度更高
-- 读路径变成双 store 协调
-- 容易在第一版就引入过多同步规则
+
+- 第一版复杂度过高
+- 双 store 协调会扩大战线
 
 结论：
-- 更适合作为第二阶段演进，不适合第一版直接上
 
-## 结论与推荐
+- 留给 P1/P2，不在当前落地
 
-推荐先落地方案 B：在 `ChunkRecord` 中内嵌 `renderCache`，并明确它是非权威、可丢弃、可重建的快速上屏缓存层。
+## 设计结论
 
-这条路线能在最少架构扰动下，直接消灭当前 `load-from-record` 的主线程热点。
+P0 采用方案 B：在 `ChunkRecord` 中内嵌 `renderCache`，但要补两个关键约束：
+
+1. 不使用 `sourceHash` 作为首版失效机制。
+2. 先打通 `renderCache` 的读写保真，再接入 runtime 消费。

-## 字段语义
+### 运行时 `Chunk` 实例状态
+
+为了避免 flush 和 unload 路径从旧快照反推出错误版本，`Chunk` 实例在 P0 必须显式持有：
+
+```js
+{
+  contentRevision: 12,
+  renderCache: { ... } | null,
+  renderCacheStatus: 'hit' | 'miss' | 'stale' | 'dirty-by-overflow'
+}
+```
+
+规则：
 
-### `version`
+- `loadFromRecord()` 负责把 `chunkRecord.contentRevision/renderCache` 挂到实例
+- runtime 修改 `blockData` 时，先更新实例 `contentRevision`
+- flush / pending unload / consolidation 写回时，以实例状态为最高优先级来源
 
-缓存结构版本号。用于未来 cache 格式升级时快速失效。
+## 为什么不用 `sourceHash`
 
-### `sourceHash`
+原方案中的 `sourceHash(blockData)` 有一个根本问题：
 
-由权威层内容计算得到的签名，至少覆盖：
+- 为了验证 cache 是否有效，runtime 仍要再次遍历整个 `blockData`
 
-- `blockData`
-- 必要时覆盖影响 mesh 的 `runtimeSeedData.structureCenters`
+这会把 P0 想消灭的主线程扫描重新引回来。即使放在 worker，也会增加加载等待。
 
-第一版可以先实现稳定但不极致高效的 hash，例如：
-- 先对 blockData key 排序
-- 再对 `{ type, orientation }` 序列化后生成字符串 hash
+因此第一版改用：
 
-要求不是密码学安全，而是稳定、一致、可检测是否过期。
+- `contentRevision` 作为权威内容版本号
+- `renderCache.contentRevision` 作为缓存绑定版本号
 
-### `meshData`
+命中条件变成：
 
-直接兼容现有 `buildMeshes()` / `replaceChunkVisibleBlocks()` 输入格式。第一版目标不是重新设计渲染提交格式，而是直接绕过主线程 `_convertScatteredBlocksToMeshData()`。
+```text
+renderCache.schemaVersion === CURRENT_SCHEMA_VERSION
+&& renderCache.contentRevision === chunkRecord.contentRevision
+&& renderCache 结构完整
+```
 
-### `visibleKeys`
+这是一组 O(1) 比较。
 
-直接恢复 chunk 的可见块索引，避免 runtime 再从 `meshData` 或 `blockData` 反推。
+## `contentRevision` 规则
 
-### `lightSources`
+### 初始值
 
-直接恢复该 chunk 内的光源编码坐标，避免 finalize 或 deferred finalize 再遍历 `blockData`。
+- 新生成 chunk：`contentRevision = 1`
+- 旧档无该字段：按 `1` 兼容读取，且视 `renderCache` 不存在
 
-## 核心原则
+### 递增时机
 
-1. `blockData` 永远权威
-2. `renderCache` 永远非权威
-3. 主线程只消费 cache，不负责修 cache
-4. cache 缺失或过期时，由 worker 重建
-5. cache 重建失败不影响世界正确性，只影响上屏延迟
+任何会改变 `blockData` 权威内容的路径都必须递增：
 
-## 生成链路
+1. 预生成新 chunk 初次写入
+2. runtime 放置/破坏方块后 flush
+3. consolidation 产出稳定新结果后准备持久化
+4. cross-region overflow 合并进 chunk 时
 
-### 链路 1：预生成阶段
+### 不递增时机
 
-由 `WorldWorker.generateRegion` 产出每个 chunk 的：
+以下情况不应递增：
 
-- `blockData`
-- `staticEntities`
-- `runtimeSeedData`
-- `renderCache`
+1. 仅 runtimeEntities 改变
+2. 仅 UI / 调试状态变化
+3. 仅 AO attribute 局部刷新但权威 `blockData` 未变
 
-再一起写入 `RegionRecord.chunks[chunkKey]`。
+### 单调性约束
 
-这样新档进入 runtime streaming 时，第一次加载就能直接消费 `renderCache`。
+`contentRevision` 必须单调递增，不允许任何持久化路径回退。
 
-### 链路 2：运行时 consolidation 完成后
+具体要求：
 
-当前 consolidation 已经在 worker 重算可见面和 AO。此时应顺手产出新的 `renderCache`，并把它与最新 `blockData` 一起回写 `WorldStore`。
+1. 新 patch 不得用更小的 `contentRevision` 覆盖更大的 `contentRevision`
+2. `renderCache.contentRevision` 必须等于其绑定的 `chunkRecord.contentRevision`
+3. 任何只补写 `renderCache` 的 patch，若携带 `contentRevision`，也必须满足不回退
 
-这样经过交互修改后的 chunk，在下一次卸载/重载时仍然能直接走快速上屏路径。
+## `renderCache` 最小字段
 
-### 链路 3：缓存缺失或失效时
+P0 先只缓存首帧快速上屏真正需要的字段：
 
-如果 `renderCache`：
+### 必需
 
-- 不存在
-- `version` 不匹配
-- `sourceHash` 不匹配
-- 结构校验失败
+- `schemaVersion`
+- `contentRevision`
+- `generatorVersion`
+- `generatedAt`
+- `meshData`
+- `visibleKeys`
 
-则：
+其中 `meshData` 第一版沿用现有 worker 结构，包含：
 
-1. runtime 发起 worker 重建请求
-2. 当前 chunk 进入“等待渲染缓存”状态
-3. worker 返回 `renderCache`
-4. 主线程只负责挂载 mesh
-5. 后台把新 cache 补写回 `WorldStore`
+- `type`
+- `count`
+- `matrices`
+- `aoLow`
+- `aoHigh`
+- `orientation`
+- `instanceIndexMap`
 
-## 运行时加载链路
+### 暂缓
 
-### 当前路径
+- `lightSources`
+- `solidBlocks`
+- 其他派生索引
 
-```text
-WorldStore chunkRecord
--> Chunk.loadFromRecord()
--> _injectBlockData()
--> _buildMeshFromExistingBlockData()
--> 遍历 blockData
--> _convertScatteredBlocksToMeshData()
--> buildMeshes()
-```
+原因：
 
-### 目标路径
+- `lightSourceCoords` 和 `solidBlocks` 目前已经在 `_injectBlockData()` 时恢复
+- 如果不连带重构这段初始化逻辑，先缓存它们收益有限，只会增大消息体和存储体积
+- 后续若继续优化 `load-from-record` 的尾部遍历，`lightSources` 是第一候选扩展字段
 
-```text
-WorldStore chunkRecord
--> Chunk.loadFromRecord()
--> _injectBlockData()   // 保留，作为运行时逻辑视图
--> validateRenderCache()
--> applyRenderCache()
--> buildMeshes(renderCache.meshData)
-```
+## `renderCache` 序列化规范
 
-### fallback 路径
+worker 侧 `meshData` 目前包含多个 TypedArray。P0 必须定义持久化格式，避免写入 IndexedDB 后结构损坏。
 
-```text
-WorldStore chunkRecord
--> renderCache invalid/missing
--> worker build render cache
--> applyRenderCache()
--> background patch WorldStore
+### 持久化格式
+
+写入 `ChunkRecord.renderCache` 时：
+
+- `Float32Array` -> 普通数组
+- `instanceIndexMap` 保持普通对象
+
+示意：
+
+```js
+{
+  matrices: Array.from(float32Matrices),
+  aoLow: Array.from(float32AoLow),
+  aoHigh: Array.from(float32AoHigh),
+  orientation: Array.from(float32Orientation),
+  instanceIndexMap: { ... }
+}
 ```
 
-## 主线程职责调整
+### 运行时恢复格式
 
-### 保留
+从 `ChunkRecord.renderCache` 读取时：
 
-1. 注入 `blockData` 到 runtime 视图
-2. 恢复 `runtimeEntities`/shadow store
-3. 最终 mesh 挂载
-4. deferred finalize
+- `matrices` 恢复为 `new Float32Array(...)`
+- `aoLow/aoHigh/orientation` 恢复为 `new Float32Array(...)`
+- `instanceIndexMap` 直接复用
 
-### 删除或降级为 fallback
+因此 P0 需要显式的：
 
-1. `_buildMeshFromExistingBlockData()` 不再是主路径
-2. `_convertScatteredBlocksToMeshData()` 不再在 `load-from-record` 期间主线程执行
-3. `visibleKeys` 不再由主线程扫描 blockData 重建
+- `serializeRenderCache()`
+- `deserializeRenderCache()`
 
-## 失效规则
+## 缓存状态机
 
-以下任一命中时，`renderCache` 失效：
+定义 4 种状态：
 
-1. `renderCache.version !== CURRENT_RENDER_CACHE_VERSION`
-2. `renderCache.generatorVersion !== CURRENT_RENDER_CACHE_GENERATOR_VERSION`
-3. `renderCache.sourceHash !== computeRenderCacheSourceHash(chunkRecord)`
-4. `meshData` 缺字段或结构非法
+### `hit`
 
-第一版不追求局部修复，直接整块 chunk cache 重建。
+- `renderCache` 存在
+- schema/version 匹配
+- 结构完整
 
-## 存储位置
+运行时行为：
 
-第一版建议直接内嵌到 `RegionRecord.chunks[chunkKey]`：
+- 直接 `_applyRenderCache()`
+- 跳过 `_buildMeshFromExistingBlockData()`
 
-```js
-region.chunks[chunkKey] = {
-  blockData,
-  staticEntities,
-  runtimeSeedData,
-  runtimeEntities,
-  renderCache
-};
+### `miss`
+
+- `renderCache` 不存在
+
+运行时行为：
+
+- 第一版可直接走现有主线程 `_buildMeshFromExistingBlockData()` 兜底
+- 若后续启用 worker fallback，则作为 P1 增强，而不是 P0 必需项
+
+### `stale`
+
+- `renderCache.contentRevision !== chunkRecord.contentRevision`
+- 或 `schemaVersion` 不匹配
+
+运行时行为：
+
+- 与 miss 相同
+
+### `dirty-by-overflow`
+
+- pregen 后 chunk 又被合并了 cross-region overflow
+- 或主线程已知该 chunk 的 cache 不再可信
+
+运行时行为：
+
+- 直接视作 miss
+- P0 不尝试在主线程同步修 cache
+
+## 字段来源优先级
+
+P0 必须明确不同运行时来源在写回时的优先级，避免旧快照覆盖新状态。
+
+优先级从高到低：
+
+1. `Chunk` 实例当前状态
+2. `pendingUnloadFlushQueue` 中较新的 chunk snapshot
+3. `_getCachedChunkRecord()` 返回值
+4. `WorldStore` 中的默认值
+
+约束：
+
+- `cachedChunkRecord` 只能补缺字段，不能覆盖实例上的 `contentRevision/renderCache`
+- `pendingUnloadFlushQueue` 中的 snapshot 必须包含 `contentRevision/renderCache`
+- 若 queue snapshot 的 revision 小于 chunk 实例 revision，禁止回写覆盖
+
+## 生成链路
+
+### 链路 1：预生成阶段
+
+`WorldWorker.generateRegion` 现有输出里已经带有 `meshData / visibleKeys`。  
+P0 直接复用这些结果构造 `renderCache`。
+
+但要注意一个现实约束：
+
+- region 结果写入前，`WorldGenerationService` 还会把历史暂存的 cross-region overflow 合并进 `blockData`
+
+因此：
+
+- 对未被 overflow 影响的 chunk，直接保留 worker 产出的 `renderCache`
+- 对被 overflow 修改过的 chunk，P0 先清空 `renderCache`，只保留更新后的 `blockData + contentRevision`
+
+不要在主线程为了补 cache 再做一轮大遍历。
+
+### 链路 2：consolidation 阶段
+
+consolidation worker 已经返回：
+
+- `meshData`
+- `visibleKeys`
+
+P0 直接在 `_applyConsolidateResult()` 成功后组装新的 `renderCache`，挂到 chunk 的稳定持久化快照上。
+
+这一步是运行时修改后“下次 reload 仍能快上屏”的关键。
+
+### 链路 3：fallback 重建
+
+当 cache miss/stale 时：
+
+1. chunk 进入 `waiting-render-cache`
+2. P0 默认直接走主线程稳定兜底 `_buildMeshFromExistingBlockData()`
+3. 后续若进入 P1，可改成 worker 根据当前 `blockData` 构建 `renderCache`
+4. worker fallback 不是 P0 必需项
+
+因此 P0 的目标是“hit 快”，不是“所有 miss 都异步化”。
+
+## 运行时加载链路
+
+### 当前路径
+
+```text
+chunkRecord
+-> loadFromRecord()
+-> assembleRuntimeBuildPhase()
+-> _buildMeshFromExistingBlockData()
+-> buildMeshes()
 ```
 
-原因：
+### 目标路径
+
+```text
+chunkRecord
+-> loadFromRecord()
+-> validateRenderCacheStatus()
+-> hit: _applyRenderCache()
+-> buildMeshes(renderCache.meshData)
+```
 
-1. 改动面最小
-2. 不需要额外 store 协议
-3. 与当前 `ChunkRecord` 读取方式兼容
+### miss/stale 路径（P0）
 
-已知代价：
-- region record 变大
-- 主线程和 worker 之间整包消息更重
+```text
+chunkRecord
+-> loadFromRecord()
+-> validateRenderCacheStatus()
+-> 主线程 _buildMeshFromExistingBlockData()
+-> buildMeshes()
+```
+
+### miss/stale 路径（P1 可选增强）
+
+```text
+chunkRecord
+-> loadFromRecord()
+-> validateRenderCacheStatus()
+-> waiting-render-cache
+-> worker build render cache
+-> _applyRenderCache()
+-> 后台补写 WorldStore
+```
 
-但这属于下一阶段要继续解决的问题，不应该阻塞第一版先把 `load-from-record` 热点拿掉。
+## 存储层约束
 
-## 第二阶段演进方向
+P0 必须先满足以下条件，否则 cache 会被写丢：
 
-第一版稳定后，可以继续评估：
+1. `WorldStore._extractChunkRecord()` 要投影 `contentRevision/renderCache`
+2. `WorldRuntime.ensureChunkData()` 要把它们传给 `Chunk.loadFromRecord()`
+3. `flushChunk()/flushAllDirty()` 在未改动 `blockData` 但补写 cache 时，不能覆盖掉已有权威数据
+4. `PersistenceWorker.applyRegionPatch()` 要允许 patch 只更新 `renderCache/contentRevision`
+5. pending unload queue 要保留最新 cache，而不是回退成旧 chunkRecord
+6. `_getCachedChunkRecord()` 只能作为补缺来源，不能覆盖实例当前 revision
+7. `applyChunkPatchToRegion()` 如遇到更小的 `contentRevision`，不得覆盖更大的现值
 
-1. `renderCache` 独立 store
-2. `PersistenceWorker` 直接提供 chunk 级投影读取
-3. `meshData` 是否改成更适合 `GlobalInstancedMeshManager` 直接消费的紧凑格式
-4. `visibleKeys` 是否需要改为 typed array / transferable 以降低 message 成本
+## 内存与体积风险
 
-## 风险与防护
+把 `meshData` 直接塞进 `ChunkRecord` 会扩大两类开销：
 
-### 风险 1：存储体积膨胀
+1. IndexedDB 中的 region record 体积
+2. `RegionCache` 常驻内存体积
 
-防护：
-- 接受这是“用空间换 runtime 时间”的设计取舍
-- 第一版只缓存确实能消灭主线程热点的字段，不扩大范围
+因此 P0 需要加观测，不先做复杂压缩：
 
-### 风险 2：缓存与权威数据不一致
+- 单 chunk `renderCache` 大小
+- 单 region 总字节数
+- `cache-hit/miss/stale` 比例
+- `load-from-record` 耗时
 
-防护：
-- 严格坚持 `blockData` 权威、`renderCache` 非权威
-- 统一用 `version + sourceHash` 判失效
-- 不做主线程修补 cache
+如果体积异常，再决定是否进入 P1 做独立 store 或压缩。
 
-### 风险 3：region 级整包传输变更重
+## 兼容与回退
 
-防护：
-- 先落地 render cache 层，验证 `load-from-record` 热点是否消失
-- 再推进 chunk 级投影读取，分阶段解决
+### 旧档兼容
 
-## 测试策略
+- 无 `contentRevision`：读取时视为 `1`
+- 无 `renderCache`：正常 miss，P0 走主线程稳定兜底，P1 可升级为 worker fallback
 
-1. 单元测试
-- `renderCache` 结构校验
-- `sourceHash` 稳定性
-- 失效判定逻辑
-- cache 缺失时 fallback worker 重建
+### 版本升级
 
-2. 集成测试
-- 新档预生成后，runtime 纯加载直接消费 cache
-- 玩家修改 chunk 后，consolidation 重建 cache 并持久化
-- chunk unload/reload 后，不再走主线程 `convertMeshData`
+- 只要 `schemaVersion` 不匹配，直接 miss
 
-3. 性能验证
-- 对比优化前后 `chunk.load-from-record`
-- 目标是把 `convertMeshDataMs` 从主线程热点中消灭
-- 验证 `StreamingPerf` 下 mutation queue 是否下降
+### 功能开关
 
-## 分阶段落地建议
+建议增加显式开关：
 
-### Phase 1
+- `ENABLE_RENDER_CACHE`
 
-1. 定义 `renderCache` 数据结构和版本号
-2. 在 `Chunk.loadFromRecord()` 中增加 `renderCache` 优先路径
-3. 把 `_buildMeshFromExistingBlockData()` 降级为 fallback
-4. 增加 worker 侧“从权威 chunkRecord 构建 renderCache”的能力
+便于：
 
-### Phase 2
+1. A/B 对比性能
+2. 问题回退
+3. 定位 cache 相关 bug
 
-1. 在预生成阶段写入 `renderCache`
-2. 在 consolidation 回包中同步更新 `renderCache`
-3. 增加持久化回写链路
+## 测试要求
 
-### Phase 3
+P0 至少覆盖：
 
-1. 评估是否拆出独立 cache store
-2. 推进 chunk 级读取投影，减少 region 整包回主线程
+1. `renderCache/contentRevision` 在 `WorldStore/WorldRuntime` 投影链路中不丢失
+2. cache hit 时 `assembleRuntimeBuildPhase()` 不再调用 `_buildMeshFromExistingBlockData()`
+3. cache miss/stale 时 P0 可稳定兜底，P1 再升级为 worker fallback
+4. pregen + overflow 场景中受影响 chunk 不错误复用旧 cache
+5. consolidation 后新 cache 会进入后续持久化写回
+6. 旧档无 cache 时能正常加载
+7. `pendingUnloadFlushQueue` / `_getCachedChunkRecord()` / patch merge 不会导致 revision 回退
+8. render cache 的 TypedArray 序列化与反序列化正确
+9. `instanceIndexMap` 在缓存读写后仍可直接使用，不需要重建
 
-## 最终结论
+## 最终建议
 
-`renderCache` 不是一层可有可无的附加缓存，而是当前 `worldStore` 架构继续向“runtime 只做上屏、不做重计算”推进时必须补齐的一层。
+P0 正确顺序应当是：
 
-它的职责边界应该非常明确：
+1. 先打通 `contentRevision/renderCache` 的读写保真
+2. 再让 pregen / consolidation 生产 cache
+3. 再让 runtime 消费 cache
+4. 最后补性能观测和 feature flag
+5. worker fallback 作为 P1 可选增强单独推进
 
-- 不代表世界真相
-- 不参与逻辑正确性判断
-- 只负责 chunk 快速上屏
-- 丢了可重建
-- 过期可失效
+核心判断标准只有两个：
 
-第一版推荐以内嵌 `ChunkRecord.renderCache` 的方式落地，先直接消灭 `load-from-record` 期间那段 `3ms ~ 10ms / chunk` 的主线程重建成本，再继续处理 region 级大对象传输和 mutation queue 吞吐问题。
+1. cache hit 时，主线程不再扫描 `blockData` 构建 `meshData`
+2. cache miss/stale 时，不会因为写回链路不完整而把缓存写丢或写脏

新增基于兴趣集调度的 chunk 加载节流方案 v2，替代 renderCache 方向：
- 设计文档：ChunkLoadScheduler 调度器 + 双层 consolidation 限流架构
- 实施计划：9 个 Task，从 feature flags 到 consolidation 队列的完整步骤
- 视觉对比：renderCache vs renderDelay 方案 CPU 尖峰分布对比图

关键改进：
- 新增 pending 过时任务淘汰机制（玩家快速移动时丢弃旧区域 key）
- consolidation 改为两层限流，保留现有 idle grace 语义不被破坏
- 首帧立即创建最近 chunk + 冷却帧控制，统一测试语义

+**Goal:** 通过“兴趣集调度 + 近场优先 + 过时任务淘汰 + consolidation 双层限流”缓解 runtime 移动时的可感知卡顿。
+
+**Architecture:**  
+`ChunkLoadScheduler` 负责 runtime 阶段的 chunk 创建节奏与优先级。  
+`_pendingDeferredConsolidationChunkKeys` 继续负责 idle grace。  
+新增 `_globalConsolidationQueue` 仅负责在 idle 窗口内串行发起 consolidation。
+
+**Tech Stack:** JavaScript ES Modules, Three.js, 现有 `World/Chunk/RuntimeIdleScheduler/ChunkAssemblyScheduler` 架构
+
+---
+
+## 文件边界
+
+**新增文件：**
+- `src/world/ChunkLoadScheduler.js` — 基于兴趣集的 chunk 调度器
+
+**修改文件：**
+- `src/constants/GameConfig.js` — 新增参数化节流配置
+- `src/world/World.js` — 接入 chunk 调度器、双层 consolidation 队列、观测指标
+- `src/world/ChunkConsolidation.js` — `scheduleConsolidation` 回接 deferred 层
+- `src/ui/HUD.js` — 展示新的 streaming 调度指标
+
+**测试文件：**
+- `src/tests/test-world.js` — 新增 chunk 节流与 consolidation 队列测试
+
+---
+
+## 实施顺序
+
+本计划刻意先做 `chunk 创建调度`，确认它本身有收益，再做 `consolidation` 二次限流。不要一开始同时改两条链路，否则难以定位收益与回归来源。
+
+---
+
+### Task 1: 参数化 Feature Flags
+
+**Files:**
+- Modify: `src/constants/GameConfig.js`
+
+- [ ] 添加以下配置项
+
+```js
+  // ==================== runtime chunk 节流配置 ====================
+  ENABLE_FRAME_THROTTLED_LOADING: true,
+  FRAME_THROTTLED_LOADING_MAX_CREATES_PER_FRAME: 1,
+  FRAME_THROTTLED_LOADING_COOLDOWN_FRAMES: 2,
+  FRAME_THROTTLED_LOADING_NEAR_RING_RADIUS: 1,
+  FRAME_THROTTLED_LOADING_DROP_STALE_PENDING: true,
+
+  // ==================== consolidation 串行化配置 ====================
+  ENABLE_CONSOLIDATION_QUEUE: true,
+  CONSOLIDATION_QUEUE_MAX_PER_IDLE_TICK: 1,
+```
+
+- [ ] 运行 `npm run lint`
+
+预期：
+- 无新增 lint 错误
+
+---
+
+### Task 2: 实现 ChunkLoadScheduler v2
+
+**Files:**
+- Create: `src/world/ChunkLoadScheduler.js`
+
+- [ ] 创建调度器，使用 `Map` 存储 pending 任务，而不是数组
+
+建议接口：
+
+```js
+class ChunkLoadScheduler {
+  constructor(world, options = {}) {}
+  refreshInterestSet(centerCx, centerCz, renderDistance) {}
+  hasPending(key) {}
+  getPendingCount() {}
+  getPendingNearCount() {}
+  getDroppedCount() {}
+  getLastCreatedDistanceSq() {}
+  processOne() {}
+  _collectInterestKeys(centerCx, centerCz, renderDistance) {}
+  _selectNextChunkKey() {}
+  _createAndLoadChunk(key) {}
+}
+```
+
+- [ ] `refreshInterestSet()` 必须完成以下行为
+
+要求：
+- 只保留当前 render distance 范围内的缺失 key
+- 已加载 chunk 不应进入 pending
+- 不在当前兴趣集内的 pending key 必须被淘汰
+- 每个 pending 项必须更新 `distanceSq` 与 `ring`
+- `ring <= nearRingRadius` 的视为近场
+
+- [ ] `processOne()` 必须完成以下行为
+
+要求：
+- 队列从空变非空时，允许首帧立即创建 1 个 chunk
+- 创建后进入冷却帧窗口
+- 冷却未结束时不再继续创建
+- 每次最多创建 `maxCreatesPerFrame`
+- 选择逻辑为：近场优先、距离优先、入队时间稳定排序
+
+- [ ] 运行 `npm run lint`
+
+预期：
+- 无新增 lint 错误
+
+---
+
+### Task 3: ChunkLoadScheduler 单元测试
+
+**Files:**
+- Modify: `src/tests/test-world.js`
+
+- [ ] 为调度器新增以下测试
+
+1. 去重：同一 key 不重复进入 pending
+2. 首帧创建：队列从空变非空时，第 1 次 `processOne()` 即可创建最近 chunk
+3. 冷却：创建后接下来的 `cooldownFrames` 内不应继续创建
+4. 淘汰：玩家移动后，旧区域 key 被移出 pending
+5. 优先级：近场 key 优先于远场 key 被创建
+
+- [ ] 若现有 `World` 构造耦合较强，可直接对 `ChunkLoadScheduler` 做局部 stub 测试
+
+- [ ] 运行浏览器测试
+
+验证方式：
+- 启动 `npm run start`
+- 打开 `http://localhost:8080/src/tests/index.html`
+
+预期：
+- 新增测试通过
+
+---
+
+### Task 4: 集成到 World.update()
+
+**Files:**
+- Modify: `src/world/World.js`
+
+- [ ] 在构造函数中初始化 `ChunkLoadScheduler`
+
+```js
+this.chunkLoadScheduler = new ChunkLoadScheduler(this, {
+  maxCreatesPerFrame: GameConfig.FRAME_THROTTLED_LOADING_MAX_CREATES_PER_FRAME,
+  cooldownFrames: GameConfig.FRAME_THROTTLED_LOADING_COOLDOWN_FRAMES,
+  nearRingRadius: GameConfig.FRAME_THROTTLED_LOADING_NEAR_RING_RADIUS
+});
+```
+
+- [ ] 保持 bootstrap 路径不变
+
+- [ ] runtime 路径改成：
+
+```js
+this.chunkLoadScheduler.refreshInterestSet(cx, cz, this.renderDistance);
+if (this.chunkLoadScheduler.processOne()) {
+  chunkTopologyChanged = true;
+}
+```
+
+- [ ] 确保 `chunkTopologyChanged` 只在实际创建 chunk 时为 `true`
+
+- [ ] 保证 feature flag 关闭时完整回退到旧逻辑
+
+- [ ] 运行 `npm run lint`
+
+---
+
+### Task 5: World.update() 集成测试
+
+**Files:**
+- Modify: `src/tests/test-world.js`
+
+- [ ] 新增以下集成测试
+
+1. bootstrap 阶段仍然同步创建整圈 chunk
+2. runtime 阶段首次进入新区域时，第 1 帧只创建 1 个 chunk
+3. 接下来的冷却帧内不继续创建
+4. 冷却结束后继续只创建 1 个 chunk
+5. 玩家从 `(0, 0)` 快速移动到远处后，pending 队列会改以新区域为主
+
+- [ ] 测试不要再使用互相矛盾的“第 1 帧不创建 / 第 1 帧创建”混合预期
+
+统一预期：
+- 队列首次变非空时允许立即创建
+- 后续受冷却窗口控制
+
+- [ ] 运行浏览器测试并确认通过
+
+---
+
+### Task 6: 增加观测指标
+
+**Files:**
+- Modify: `src/world/World.js`
+- Modify: `src/ui/HUD.js`
+
+- [ ] 在 `consumeStreamingPerfSnapshot()` 中增加：
+
+```js
+pendingChunkLoads
+pendingNearChunkLoads
+droppedPendingLoads
+lastCreatedChunkDistance
+pendingDeferredConsolidation
+pendingGlobalConsolidation
+```
+
+- [ ] 在 HUD 中增加对应展示
+
+建议格式：
+- `loadQ total/near`
+- `drop stale`
+- `lastDist`
+- `deferredCon`
+- `globalCon`
+
+- [ ] 保持现有日志结构兼容，不删除旧指标
+
+---
+
+### Task 7: 接入 consolidation 双层限流
+
+**Files:**
+- Modify: `src/world/World.js`
+- Modify: `src/world/ChunkConsolidation.js`
+
+- [ ] 在 `World` 构造函数中新增：
+
+```js
+this._globalConsolidationQueue = new Set();
+```
+
+- [ ] 新增 `queueConsolidation(chunk)` 与 `_processGlobalConsolidationQueue()`
+
+要求：
+- `queueConsolidation()` 只负责加入 global queue
+- `_processGlobalConsolidationQueue()` 每次最多真正 `consolidate()` 1 个 chunk
+- global queue 中已失效、已卸载、已 clean 的 chunk 要自动跳过
+
+- [ ] 不删除现有 `_pendingDeferredConsolidationChunkKeys`
+
+- [ ] 修改 `_processDeferredConsolidationQueue()`：
+
+要求：
+- 继续保留当前的 `idle grace` 判定
+- 在启用 `ENABLE_CONSOLIDATION_QUEUE` 时，不再直接触发 `chunk.scheduleConsolidation()`
+- 改为把满足条件的 chunk 从 deferred set 转移到 global queue
+- feature flag 关闭时保留旧逻辑
+
+- [ ] 修改 `Chunk.prototype.scheduleConsolidation()`
+
+要求：
+- 新逻辑下仍然先进入 `queueDeferredConsolidation()`
+- 不要直接跳到 global queue
+- feature flag 关闭时保留旧的阈值立即触发和防抖逻辑
+
+- [ ] 运行 `npm run lint`
+
+---
+
+### Task 8: consolidation 队列测试
+
+**Files:**
+- Modify: `src/tests/test-world.js`
+
+- [ ] 增加以下测试
+
+1. dirty chunk 调 `scheduleConsolidation()` 后先进入 deferred queue
+2. active streaming 期间 `_processDeferredConsolidationQueue()` 不应把任务推进到 global queue
+3. idle grace 满足后，deferred queue 可把任务转移到 global queue
+4. `_processGlobalConsolidationQueue()` 每次只处理 1 个
+5. 失效 chunk 会在处理时被自动跳过
+
+- [ ] 尽量用 stub chunk 验证队列语义，而不是依赖完整 worker
+
+- [ ] 运行浏览器测试并确认通过
+
+---
+
+### Task 9: 手工验证
+
+**Files:**
+- 无代码新增，运行现有项目
+
+- [ ] 启动 `npm run start`
+
+- [ ] 在以下场景下观察 HUD / 控制台 StreamingPerf
+
+场景：
+1. 初始 bootstrap 完成后进入 runtime
+2. 匀速向新区域移动
+3. 快速飞行或传送到远处
+4. 批量放置/删除方块后等待 idle
+
+- [ ] 重点观察以下信号
+
+检查点：
+- `pendingChunkLoads` 不应长期堆积不降
+- `pendingNearChunkLoads` 不应长期大于 0
+- `droppedPendingLoads` 在快速移动时应增长
+- `pendingGlobalConsolidation` 不应在持续移动时快速上涨
+- active streaming 期间 consolidation 不应频繁抢占
+
+---
+
+## 完成标准
+
+满足以下条件才算该计划完成：
+
+1. bootstrap 行为未回归
+2. runtime 下 chunk 创建不再整圈同步爆发
+3. 近场优先可感知成立，不出现明显“远处先出来、脚下仍空”的退化
+4. consolidation 仍被延后到 idle 窗口，而不是重新抢占 runtime
+5. 所有新增测试通过
+6. `npm run lint` 通过
+
+## 暂不做的事
+
+1. 不再尝试 `renderCache`
+2. 不优化 `loadFromRecord()` 内部 `blockData -> meshData` 的根因成本
+3. 不调整 `ChunkAssemblyScheduler` 预算
+4. 不修改持久化 schema

+# Frame-Throttled Chunk Loading Design v2
+
+日期：2026-05-02
+分支：`gen-big-map-first`
+定位：在放弃 `renderCache` 方案后，以较低技术复杂度削平 runtime chunk 加载尖峰
+
+## 背景
+
+当前 `runtime-streaming` 阶段的 chunk 热路径，仍然会在短时间内集中触发以下工作：
+
+1. `World.update()` 单帧内创建大量缺失 chunk
+2. `loadFromRecord()` 在主线程同步扫描 `blockData` 并生成 `meshData`
+3. Worker 回包后的装配、scatter、实例提交形成阶段性洪峰
+4. 玩家交互产生的 dirty chunk 在后续又可能集中触发 consolidation
+
+此前的理想方案是为 `ChunkRecord` 引入 `renderCache`，跳过 `blockData -> meshData` 的主线程重建成本。这个方向在逻辑上成立，但当前实现复杂度过高，连续几次改造都带来了较多 bug，因此本轮不再继续推进该方向。
+
+因此，本方案明确转向一个次优但可实施的目标：不试图降低单个 chunk 的总 CPU 成本，而是通过调度与限流，把原本集中发生的 CPU 峰值摊平到多个帧和 idle 窗口中，优先改善体感卡顿。
+
+## 目标
+
+1. runtime 阶段不再在单帧内同步创建整圈缺失 chunk
+2. chunk 创建顺序必须优先保障玩家近场可见区域
+3. 玩家快速移动时，旧区域 pending 加载任务可被淘汰，避免预算浪费
+4. consolidation 保留现有 idle/backpressure 语义，只在空闲窗口内进一步串行化
+5. bootstrap 阶段保持原有行为不变
+6. 提供 feature flag 和性能观测，支持快速回退与调参
+
+## 非目标
+
+1. 不解决 `loadFromRecord()` 内部 `blockData` 扫描的根因成本
+2. 不改动 `ChunkAssemblyScheduler` 主流程
+3. 不引入新的持久化 schema 或 `renderCache`
+4. 不承诺提升极端移动速度下的总吞吐，只承诺削峰
+
+## 总体策略
+
+方案拆成两条独立链路：
+
+1. `ChunkLoadScheduler`
+运行时只负责“发现缺失 chunk 后，何时创建、先创建谁、丢弃谁”。
+
+2. `GlobalConsolidationQueue`
+仅在保留现有 idle grace 的前提下，再把可执行的 consolidation 串行化，防止多个 chunk 同时发起 worker 优化请求。
+
+这两条链路是互相独立的。第一阶段先落地 chunk 创建节流和优先级，确认它本身可以缓解尖峰；第二阶段再接入 consolidation 全局串行化。
+
+## 架构
+
+```text
+World.update()
+    ↓ 计算当前玩家所在 chunk
+    ↓ 生成本帧目标兴趣集（render distance 范围内）
+ChunkLoadScheduler.refreshInterestSet()
+    ↓ 丢弃不再需要的 pending key
+    ↓ 更新每个 key 的优先级（内圈优先、距离优先）
+ChunkLoadScheduler.processOne()
+    ↓ 如果本帧允许创建，则只创建 1 个当前最重要的 chunk
+    ↓ new Chunk() + scene.add()
+    ↓ _requestRuntimeChunkRecord()
+    ↓ 后续仍由 ChunkAssemblyScheduler / GlobalInstancedMeshManager 处理
+
+玩家交互或批量操作
+    ↓ chunk.scheduleConsolidation()
+    ↓ 进入 deferred-consolidation 候选集合
+RuntimeIdleScheduler 判断 idle grace 满足
+    ↓ 将“可执行 chunk”转移到 GlobalConsolidationQueue
+GlobalConsolidationQueue.processOne()
+    ↓ 每个 idle 窗口只发起 1 个 chunk.consolidate()
+```
+
+## 设计详情
+
+### Section 1: ChunkLoadScheduler 升级为兴趣集调度器
+
+**新增文件**: `src/world/ChunkLoadScheduler.js`
+
+核心职责不再是一个简单 FIFO 队列，而是一个“小型调度器”：
+
+1. 维护当前 `pendingLoads`
+2. 维护本帧 `interestSet`
+3. 按玩家当前位置重新计算优先级
+4. 丢弃不在兴趣集中的过时 key
+5. 控制首帧立即创建和后续冷却节奏
+
+建议数据结构：
+
+```js
+class ChunkLoadScheduler {
+  constructor(world, options = {}) {
+    this.world = world;
+    this.pendingLoads = new Map(); // key -> { cx, cz, distanceSq, ring, enqueuedAtFrame }
+    this.frameCounter = 0;
+    this.cooldownFrames = options.cooldownFrames ?? 2;
+    this.maxCreatesPerFrame = options.maxCreatesPerFrame ?? 1;
+    this.nearRingRadius = options.nearRingRadius ?? 1;
+    this.framesUntilNextCreate = 0;
+    this.lastPlayerChunkKey = null;
+    this.stats = {
+      droppedPendingLoads: 0,
+      createdLoads: 0,
+      lastCreatedDistanceSq: -1
+    };
+  }
+}
+```
+
+关键规则：
+
+1. 不再提供仅基于 `enqueue()` 的盲目累积行为
+2. 每帧由 `World.update()` 调用 `refreshInterestSet(centerCx, centerCz, renderDistance)`
+3. `refreshInterestSet()` 会：
+   - 生成当前兴趣集
+   - 删除已不在兴趣集中的 pending key
+   - 为新 key 建立 pending 记录
+   - 按与玩家距离更新优先级元数据
+4. `processOne()` 不按插入顺序出队，而是选择：
+   - 内圈优先
+   - 距离近优先
+   - 同优先级下按较早入队顺序稳定排序
+5. 当队列从空变为非空时，允许首帧立即创建 1 个最近 chunk
+6. 创建后进入冷却，后续 `cooldownFrames` 帧内不再创建新的 chunk
+
+这套规则的核心目的是避免“削峰成功，但近场缺块时间过长”。
+
+### Section 2: World.update() 集成方式
+
+**修改**: `src/world/World.js`
+
+bootstrap 阶段保持原有同步创建逻辑不变。
+
+runtime 阶段改为三步：
+
+1. 生成当前目标兴趣集
+2. 让 `ChunkLoadScheduler` 清理过时 pending 并刷新优先级
+3. 若本帧允许创建，则只创建 1 个最高优先级 chunk
+
+伪代码：
+
+```js
+if (this.bootstrapState.phase === 'bootstrapping' || !GameConfig.ENABLE_FRAME_THROTTLED_LOADING) {
+  // 原有同步路径不变
+} else {
+  this.chunkLoadScheduler.refreshInterestSet(cx, cz, this.renderDistance);
+  if (this.chunkLoadScheduler.processOne()) {
+    chunkTopologyChanged = true;
+  }
+}
+```
+
+`refreshInterestSet()` 内部需要保证：
+
+1. 只把当前渲染距离内且尚未加载的 key 纳入候选
+2. 已经 `this.chunks.has(key)` 的 key 不进入 pending
+3. 已脱离兴趣集的 pending key 被淘汰
+4. 玩家跨 chunk 快速移动时，调度器立刻改以新中心重新排序
+
+### Section 3: 节流参数改为策略化配置
+
+**修改**: `src/constants/GameConfig.js`
+
+不建议把策略写死在实现内部，建议显式配置：
+
+```js
+ENABLE_FRAME_THROTTLED_LOADING: true,
+FRAME_THROTTLED_LOADING_MAX_CREATES_PER_FRAME: 1,
+FRAME_THROTTLED_LOADING_COOLDOWN_FRAMES: 2,
+FRAME_THROTTLED_LOADING_NEAR_RING_RADIUS: 1,
+FRAME_THROTTLED_LOADING_DROP_STALE_PENDING: true,
+
+ENABLE_CONSOLIDATION_QUEUE: true,
+CONSOLIDATION_QUEUE_MAX_PER_IDLE_TICK: 1,
+```
+
+这样后续可以根据体感和观测数据迭代调参，而不需要改设计主干。
+
+### Section 4: Consolidation 改为“两层限流”，不破坏现有 idle grace
+
+**修改**: `src/world/World.js`
+**修改**: `src/world/ChunkConsolidation.js`
+
+这是 v2 和 v1 最大的差别。
+
+v1 的问题是想用 `GlobalConsolidationQueue` 直接替代现有 deferred idle 逻辑，容易把本来已经后移的工作又拉回 runtime 活跃阶段。
+
+v2 改成两层：
+
+1. 第一层：保留现有 `_pendingDeferredConsolidationChunkKeys`
+   这层负责“只有在 streaming activity 停下来一段时间后，才允许进入下一步”。
+
+2. 第二层：新增 `_globalConsolidationQueue`
+   这层负责“在已经满足 idle 条件后，也不要让多个 chunk 同时发起 consolidation 请求，而是一次只处理 1 个”。
+
+数据流：
+
+```text
+chunk.scheduleConsolidation()
+  -> world.queueDeferredConsolidation(chunk)
+
+World._processDeferredConsolidationQueue()
+  -> 仅在 idle grace 满足时运行
+  -> 将可执行 chunk 从 deferred set 转移到 global queue
+
+World._processGlobalConsolidationQueue()
+  -> 每次只处理 1 个
+  -> chunk.consolidate()
+```
+
+因此，`scheduleConsolidation()` 在启用新特性后，不应该直接调用 `queueConsolidation()`，而应该继续进入 deferred 层。真正进入 global queue 的时机，必须由 `_processDeferredConsolidationQueue()` 决定。
+
+### Section 5: ChunkConsolidation 的行为调整
+
+建议改成：
+
+```js
+Chunk.prototype.scheduleConsolidation = function() {
+  if (this.isConsolidating || !this.isReady) return;
+  if (this.deferConsolidation) return;
+  if (this.dirtyBlocks <= 0) return;
+
+  if (this.consolidationTimer) {
+    clearTimeout(this.consolidationTimer);
+    this.consolidationTimer = null;
+  }
+
+  if (GameConfig.ENABLE_CONSOLIDATION_QUEUE) {
+    this.world?.queueDeferredConsolidation?.(this);
+    return;
+  }
+
+  if (this.dirtyBlocks >= DIRTY_THRESHOLD) {
+    this.consolidate();
+  } else {
+    this.consolidationTimer = setTimeout(() => {
+      this.consolidate();
+    }, CONSOLIDATION_DELAY);
+  }
+};
+```
+
+这里的关键是：
+
+1. 不跳过现有 deferred 层
+2. 不改变 feature flag 关闭时的旧逻辑
+3. 兼容 `dirtyBlocks` 阈值和防抖的回退行为
+
+### Section 6: RuntimeIdleScheduler 的接入方式
+
+**修改**: `World._registerRuntimeIdleTasks()`
+
+不再把旧的 `deferred-consolidation` 任务直接替换掉，而是拆成两段：
+
+1. `deferred-consolidation-candidate`
+负责在 idle grace 满足时，把可执行 chunk 转移到 global queue
+
+2. `global-consolidation`
+负责从 global queue 中一次取 1 个真正发起 consolidation
+
+示意：
+
+```js
+this.runtimeIdleScheduler.registerTask({
+  id: 'deferred-consolidation-candidate',
+  priority: 50,
+  minIdleMs: RUNTIME_DEFERRED_CONSOLIDATION_IDLE_GRACE_MS,
+  run: () => {
+    const moved = this._processDeferredConsolidationQueue();
+    return { didWork: moved > 0 };
+  }
+});
+
+this.runtimeIdleScheduler.registerTask({
+  id: 'global-consolidation',
+  priority: 45,
+  minIdleMs: RUNTIME_DEFERRED_CONSOLIDATION_IDLE_GRACE_MS,
+  run: () => {
+    if (!GameConfig.ENABLE_CONSOLIDATION_QUEUE) return { didWork: false };
+    const processed = this._processGlobalConsolidationQueue();
+    return { didWork: processed > 0 };
+  }
+});
+```
+
+### Section 7: 观测指标
+
+**修改**: `World.consumeStreamingPerfSnapshot()`
+**修改**: `HUD.formatStreamingPerf()`
+
+新增以下观测数据：
+
+1. `pendingChunkLoads`
+2. `pendingNearChunkLoads`
+3. `droppedPendingLoads`
+4. `lastCreatedChunkDistance`
+5. `pendingDeferredConsolidation`
+6. `pendingGlobalConsolidation`
+
+这些指标比单纯显示“队列长度”更有意义，因为它们能直接回答：
+
+1. 队列有没有积压
+2. 近场 chunk 是否被饿死
+3. 玩家快速移动时是否存在大量过时任务
+4. consolidation 是否真的被后移到 idle 窗口
+
+### Section 8: 风险与缓解
+
+| 风险 | 缓解 |
+|------|------|
+| 玩家快速移动导致 pending 任务失效 | 每帧刷新兴趣集，淘汰不在当前视野需求内的 key |
+| 近处 chunk 被远处 chunk 抢占 | 内圈优先 + 距离优先 + 首帧立即创建最近 chunk |
+| 节流过强导致世界出现明显空窗 | 参数化调节 `cooldownFrames`，保留 feature flag 回退 |
+| consolidation 抢占 runtime 预算 | 保留现有 idle grace，仅在满足空闲窗口后串行发起 |
+| 方案只能削峰，不能降低单 chunk 总成本 | 明确这是次优可实施方案，不与 `renderCache` 的目标混淆 |
+
+## 测试要求
+
+1. bootstrap 阶段行为不变
+2. runtime 阶段每次只允许创建最多 1 个 chunk
+3. 队列从空变非空时，首帧允许立即创建 1 个最近 chunk
+4. 冷却帧未过时，不应继续创建新的 chunk
+5. 玩家快速移动后，旧区域 pending key 会被清理
+6. 近场和远场同时缺失时，必须优先创建近场 chunk
+7. consolidation 在 active streaming 期间不能直接发起 worker 请求
+8. idle grace 满足后，global consolidation queue 每次只处理 1 个 chunk
+9. feature flag 关闭时，完整回退到旧行为
+
+## 改动文件清单
+
+| 文件 | 操作 | 说明 |
+|------|------|------|
+| `src/world/ChunkLoadScheduler.js` | 新增 | 运行时兴趣集调度器 |
+| `src/world/World.js` | 修改 | 集成 chunk 节流、双层 consolidation 队列、性能观测 |
+| `src/world/ChunkConsolidation.js` | 修改 | `scheduleConsolidation` 接回 deferred 层 |
+| `src/constants/GameConfig.js` | 修改 | 增加节流参数与 feature flags |
+| `src/ui/HUD.js` | 修改 | 展示新的 streaming 调度指标 |

+
+当前 `ChunkAssemblyScheduler` 的预算只在 task 之间生效，不能打断单个 `runtime-build`。`assembleRuntimeBuildPhase()` 内部仍会同步执行 `_buildMeshFromExistingBlockData()`，包含：
+
+1. 遍历 `blockData`
+2. 生成 `blocks`
+3. 转换 `meshData`
+4. 构建 `visibleKeys`
+5. 调用 `buildMeshes()`
+
+因此本轮不能声称“彻底解决 runtime-build 长任务”。更稳妥的做法是：
+
+1. bootstrap 阶段保持当前 `budgetMs/maxTasks`
+2. runtime 阶段使用配置化的更小 `maxTasks`，默认每帧最多处理 1 个 runtime assembly task
+3. 保留现有优先级排序，近场 task 仍优先
+4. 在 `chunk-assembly.task` 或 streaming snapshot 中暴露 `runtimeBuildLastMs`、`runtimeBuildMaxMs`、`runtimeBuildLongTaskCount`
+5. 如果观测显示单个 runtime-build 仍稳定超过帧预算，再进入后续阶段做 runtime-build 分片或小范围 renderCache

+### Task 1: PersistenceWorker — 添加 regionCache 和 getChunkRecord
+
+**Files:**
+- Modify: `src/workers/PersistenceWorker.js`
+
+- [ ] **Step 1: 添加 regionCache 和 LRU 配置常量**
+
+在 `WORLD_OVERFLOW_STORE` 常量之后添加：
+
+```js
+// Region 缓存：Worker 侧 LRU 缓存，避免重复读取 IndexedDB
+const regionCache = new Map(); // regionKey → regionData
+const REGION_CACHE_MAX_SIZE = 6; // 保持 6 个 region（~54MB），覆盖玩家渲染距离 + 边界过渡
+```
+
+- [ ] **Step 2: 添加 getChunkRecord 函数**
+
+在 `getRegionRecord` 函数之后添加：
+
+```js
+/**
+ * 从 Worker 侧 region 缓存中裁剪出单个 chunk 数据
+ * 缓存未命中时从 IndexedDB 读取并缓存
+ * @param {string} regionKey - "rx,rz"
+ * @param {string} chunkKey - "cx,cz"

+    runtimeEntities: chunkData.runtimeEntities || { turrets: [], zombieNests: [], minecarts: [] }
+  };
+}
+```
+
+- [ ] **Step 3: 添加 postMessage action handler**
+
+在 `self.onmessage` 的 switch 语句中，`case 'getRegionRecord':` 之后添加：
+
+```js
+case 'getChunkRecord':
+  result = await getChunkRecord(payload.regionKey, payload.chunkKey, payload.cx, payload.cz);
+  break;
+```
+
+- [ ] **Step 4: 验证 lint 通过**

+
+### Task 2: WorldStore — 替换 getChunkRecord 实现
+
+**Files:**
+- Modify: `src/world/WorldStore.js`
+
+- [ ] **Step 1: 替换 getChunkRecord 方法**
+
+将现有的 `getChunkRecord` 方法（第 140-144 行）替换为：
+
+```js

+
+**Files:**
+- Modify: `src/world/WorldRuntime.js`
+
+- [ ] **Step 1: 替换 ensureChunkData 方法**
+
+将现有的 `ensureChunkData` 方法（第 87-119 行）替换为：
+
+```js
+/**

+### Task 4: 更新测试 — mock getChunkRecord 替代 getRegionRecord
+
+**Files:**
+- Modify: `src/tests/test-world-runtime.js`
+
+- [ ] **Step 1: 更新第一个测试 — region 不存在时返回 missing-chunk**
+
+将第 8-19 行的测试替换为：

+
+注意：原来的测试名 `missing-region` 改为 `missing-chunk`，因为新的实现中不区分 region 缺失和 chunk 缺失，统一返回 `missing-chunk`。
+
+- [ ] **Step 2: 删除第二个测试（region 存在但 chunk 不存在）**
+
+这个场景现在由 `getChunkRecord` 返回 null 覆盖，与第一个测试合并。删除第 21-35 行的测试。

+
+- [ ] **Step 5: 更新第五个测试 — 无旧档时补空结构**
+
+将第 108-145 行的测试替换为：
+
+```js
+test('ensureChunkData - 缺失 runtimeEntities 且无旧档时应补空结构且不回写', async () => {
+  const originalWorldStore = globalThis._worldStore;
+  const putCalls = [];
+  const chunkRecordWithoutEntities = {

+  assertEqual(putCalls.length, 0, '无旧档数据时不应发生回填');
+
+  globalThis._worldStore = originalWorldStore;
+});
+```
+
+- [ ] **Step 6: 更新第 487-555 行的测试 — flushBeforeUnload 后读取缓存**
+
+这个测试中的 `getRegionRecord` mock 需要改为 `getChunkRecord`：
+
+将第 493-499 行的 mock 替换为：
+
+```js
+globalThis._worldStore = {
+  putChunkRecord: async (cx, cz, record) => {

-**Goal:** 将 chunk 读取路径从 region 级（9MB 传输）改为 chunk 级（100KB 传输），在 PersistenceWorker 侧实现 region 缓存和裁剪。
+**Goal:** 将单 chunk 读取热路径从 “主线程拉取整包 RegionRecord 再裁剪” 改为 “PersistenceWorker 内裁剪后只返回目标 ChunkRecord”，显著降低 `postMessage` 传输体积，并保持运行时写回链路与数据一致性不退化。
 
-**Architecture:** 在 PersistenceWorker 内添加 LRU region 缓存（max 6），新增 `getChunkRecord` action 直接在 Worker 内裁剪单个 chunk 数据返回。WorldStore 的 `getChunkRecord` 改为直接调用 Worker action，不再调用 `getRegionRecord`。WorldRuntime 的 `ensureChunkData` 简化为调用 `getChunkRecord` 而非 `ensureRegion`。
+**Architecture:** PersistenceWorker 维护 Worker 侧 `regionCache`，`getChunkRecord` 在 Worker 内命中缓存或读取一次完整 region 后，只返回目标 chunk。WorldStore 的 `getChunkRecord` 改为直接调用 Worker action。WorldRuntime 的 `ensureChunkData` 改为直接读取 chunk，但仍需把读到的 chunk 注入运行时 `_regionCache`，以维持现有 flush/unload 回退逻辑所需的最小基线数据。
 
 **Tech Stack:** JavaScript, IndexedDB, Web Workers, postMessage
 
 ---
 
+## 设计约束
+
+### 本次优化范围
+
+- 只优化**单 chunk 加载热路径**：
+  - `WorldRuntime.ensureChunkData()`
+  - `WorldStore.getChunkRecord()`
+  - `PersistenceWorker.getChunkRecord()`
+- 保留现有 region 级 API：
+  - `getRegionRecord()`
+  - `ensureRegion()`
+  - `prefetchRegions()`
+  - `getChunkRecordsInRegion()`
+- 这些 region 级路径本次不是优化目标，允许继续传输整包 region。
+
+### 非目标
+
+- 不改变 IndexedDB 的物理存储粒度，仍以 `RegionRecord` 为落盘单位。
+- 不重构 `WorldRuntime` 的 flush / unload 架构。
+- 不把主线程 `_regionCache` 改造成新的通用 chunk cache 系统，只补足当前写回链路依赖的最小基线数据。
+
+### 正确性要求
+
+- Worker 侧新增缓存后，所有 Worker 内写路径都必须同步更新或失效缓存，不能出现读到旧 region 的情况。
+- `WorldRuntime.ensureChunkData()` 改走 chunk 读取后，后续 `_getCachedChunkRecord()`、`_resolveStaticEntities()`、`_resolveRuntimeSeedData()`、`flushBeforeUnload()` 不得因拿不到基线数据而退化。
+- 新语义下，`ensureChunkData()` 对 “region 不存在” 和 “chunk 不存在” 统一返回 `missing-chunk`。
+
+### Worker Cache 语义
+
+- `regionCache` 使用 `Map` 实现 LRU。
+- **命中时必须刷新新鲜度**：`delete(regionKey)` 后 `set(regionKey, region)`。
+- **新增/写入时也要刷新顺序**。
+- 淘汰规则：超过 `REGION_CACHE_MAX_SIZE` 时，删除 `Map.keys().next().value`。
+- `clearWorld()` 后必须清空 `regionCache`。
+
+### WorldRuntime 运行时缓存语义
+
+- `_regionCache` 允许保存**部分 region**。
+- 部分 region 仅表示“当前已读取/已写回过的 chunk 子集”，不能再隐含“这个 region 已完整加载”。
+- `ensureChunkData()` 读取到 `chunkRecord` 后，必须把它写入 `_regionCache` 对应 region 的 `chunks[chunkKey]`，并维护 `chunkKeys`，供后续 flush/unload 回退逻辑使用。
+- `ensureRegion()` 仍然返回完整 region；两种来源可共存，后写入者覆盖同 chunk key。

+
+将 `saveRegionRecord` 改为在 `store.put(...)` 成功后调用 `touchRegionCache(regionKey, record)`。如果实现形式不方便在 `performTransaction` 内回调，也可以在 `await` 完成后更新缓存，但必须保证写成功后 cache 与 DB 同步。

将 ensureChunkData 的读取路径从整包 region（9MB）改为 chunk 级裁剪（~100KB），
postMessage 传输量降低约 90%。

核心变更：
- PersistenceWorker 新增 LRU region 缓存（最多 6 个 region），新增 getChunkRecord
  方法，命中缓存时直接裁剪目标 chunk 返回，未命中时读取 DB 并缓存
- WorldStore.getChunkRecord 改为直接调用 Worker 的 getChunkRecord action，
  不再在主线程裁剪整包 region
- WorldRuntime.ensureChunkData 走 chunk 级读取，不再调用 ensureRegion
- 新增 _upsertRegionCacheChunkRecord 维持运行时最小 region 基线（__partial 标记）
- flushAllDirty 对 partial region 走 applyRegionPatch 增量写，避免覆盖未加载 chunk
- 引入 __runtimeEntitiesWasDefault 标记解决 Worker 侧默认值填充导致的旧档迁移跳过问题
- 写路径深 clone（structuredClone）避免 applyRegionPatch 原地修改污染缓存
- 更新测试 mocks 从 getRegionRecord 改为 getChunkRecord，新增 partial region 测试

+# Chunk-Level Read Path Design
+
+> **Problem:** `getRegionRecord` returns the entire 8×8 region (9MB) to read a single chunk's data. Worker-side region caching eliminates repeated DB reads while keeping transfer size at 100KB.
+
+## 1. Root Cause
+
+| Component | Current Behavior | Problem |
+|-----------|-----------------|---------|
+| `WorldRuntime.ensureChunkData(cx, cz)` | Calls `ensureRegion(rx, rz)` → `getRegionRecord` | Downloads 9MB region to get 1/64 (100KB) |
+| `WorldRuntime.ensureRegion` | Caches full region on main thread | 9MB region cached in main thread memory |
+| `PersistenceWorker` | Reads and returns full region from IndexedDB | 9MB structured clone transfer per region miss |
+
+Data flow:
+```
+ensureChunkData(cx, cz)
+  → ensureRegion(rx, rz)
+    → worldStore.getRegionRecord(rx, rz)
+      → PersistenceWorker.postMessage('getRegionRecord')
+        → IndexedDB read (9MB)
+        → postMessage returns 9MB region    ← bottleneck
+    → region.chunks[chunkKey]               ← client-side crop on main thread
+```
+
+## 2. Proposed Architecture
+
+### Core Change
+
+Move region caching and chunk extraction from the main thread to the PersistenceWorker. The Worker becomes the authoritative cache and returns only the requested chunk's data.
+
+### New Data Flow
+
+```
+ensureChunkData(cx, cz)
+  → ensureChunkRecord(cx, cz)               ← new method
+    → worldStore.getChunkRecord(cx, cz)      ← new method
+      → PersistenceWorker.postMessage('getChunkRecord', { regionKey, chunkKey })
+        → Worker checks regionCache           ← Worker-side LRU cache
+          - HIT: crop from cache, return chunk (100KB)
+          - MISS: read region from IndexedDB, cache it, crop, return chunk (100KB)
+```
+
+### Transfer Size Comparison
+
+| Scenario | Before | After |
+|----------|--------|-------|
+| First chunk in a new region | 9MB | 100KB |
+| 2nd chunk in same region | 9MB | 100KB |
+| 49 chunks across 4 regions | 36MB | 4.9MB |
+
+## 3. Component Design
+
+### 3.1 PersistenceWorker — Region Cache + getChunkRecord
+
+Add an in-memory LRU cache inside the Worker:
+
+```js
+const regionCache = new Map(); // regionKey → regionData
+const REGION_CACHE_MAX_SIZE = 6; // Keep 6 regions (~54MB max)
+
+function getChunkRecord(regionKey, chunkKey, cx, cz) {
+  let region = regionCache.get(regionKey);
+  if (!region) {
+    region = performTransaction(db, WORLD_REGION_STORE, 'readonly',
+      (store) => store.get(regionKey)
+    );
+    if (region) {
+      regionCache.set(regionKey, region.data);
+      // LRU eviction
+      while (regionCache.size > REGION_CACHE_MAX_SIZE) {
+        const firstKey = regionCache.keys().next().value;
+        regionCache.delete(firstKey);
+      }
+    } else {
+      return null;
+    }
+  }
+  const chunkData = region.chunks?.[chunkKey];
+  if (!chunkData) return null;
+  return {
+    cx, cz,
+    blockData: chunkData.blockData || {},
+    staticEntities: chunkData.staticEntities || [],
+    runtimeSeedData: chunkData.runtimeSeedData || {},
+    runtimeEntities: chunkData.runtimeEntities || { turrets: [], zombieNests: [], minecarts: [] }
+  };
+}
+```
+
+New `postMessage` action:
+```js
+case 'getChunkRecord':
+  result = await getChunkRecord(payload.regionKey, payload.chunkKey, payload.cx, payload.cz);
+  break;
+```
+
+### 3.2 WorldStore — getChunkRecord Method
+
+Add `getChunkRecord(cx, cz)` to `WorldStore.js`:
+
+```js
+async getChunkRecord(cx, cz) {
+  const { rx, rz } = this.chunkToRegion(cx, cz);
+  const regionKey = this.regionKey(rx, rz);
+  const chunkKey = this.chunkKey(cx, cz);
+  return getPersistenceService().postMessage('getChunkRecord', {
+    regionKey, chunkKey, cx, cz
+  });
+}
+```
+
+Note: This **shadows** the existing `getChunkRecord` method which currently calls `getRegionRecord` and crops on the main thread. The old implementation becomes dead code and will be removed.
+
+### 3.3 WorldRuntime — ensureChunkRecord
+
+Replace `ensureChunkData`'s internal path to use chunk-level reads:
+
+```js
+async ensureChunkData(cx, cz) {
+  const chunkRecord = await this._worldStore.getChunkRecord(cx, cz);
+
+  if (!chunkRecord) {
+    return { status: 'missing-chunk' };
+  }
+
+  // Hydrate legacy entities if needed
+  if (!chunkRecord.runtimeEntities) {
+    await this._hydrateLegacyRuntimeEntities(cx, cz, chunkRecord);
+  }
+
+  return {
+    status: 'ready',
+    chunkRecord
+  };
+}
+```
+
+`ensureRegion` is no longer called from the read path. It remains available for:
+- `flushAllDirty` (write path: still writes regions)
+- `expandWorld` (may still need region-level prefetch)
+
+### 3.4 Region Cache Eviction Strategy
+
+Worker-side cache uses LRU with max 6 regions (~54MB). This is chosen because:
+- Player render distance = 3 → 7×7 = 49 chunks
+- 49 chunks span at most 4 regions
+- Cache 6 regions covers the player's area + 1 margin for smooth boundary transitions
+- 54MB in a Worker is acceptable (dedicated process, no UI thread impact)
+
+The existing main-thread `_regionCache` in `WorldRuntime` is **preserved** for backward compatibility but no longer the primary read path. It can be cleaned up in a future refactor.
+
+## 4. Files Changed
+
+| File | Change |
+|------|--------|
+| `src/workers/PersistenceWorker.js` | Add `regionCache`, `getChunkRecord()` function, new `postMessage` action |
+| `src/world/WorldStore.js` | Replace `getChunkRecord` implementation to call Worker action directly |
+| `src/world/WorldRuntime.js` | Simplify `ensureChunkData` to call `getChunkRecord` instead of `ensureRegion` |
+
+## 5. Write Path (Unchanged)
+
+Write path remains region-level for batch efficiency:
+- `saveRegionRecord` → writes entire region to IndexedDB
+- `applyRegionPatch` → reads-modifies-writes region in Worker
+- `flushAllDirty` → batches chunk mutations into region writes
+
+Read and write paths are decoupled: reads are chunk-level (precise), writes are region-level (batch efficient).
+
+## 6. Error Handling
+
+| Error | Behavior |
+|-------|----------|
+| IndexedDB read fails | Return null, chunk falls back to generation path |
+| Chunk not found in region | Return `{ status: 'missing-chunk' }` |
+| Region not found in IndexedDB | Return `{ status: 'missing-region' }` |
+| Worker communication fails | Promise rejects, caller retries on next frame |
+
+## 7. Testing Strategy
+
+- Existing tests in `src/tests/test-world-runtime.js` mock `getRegionRecord` — update mocks to use `getChunkRecord`
+- Existing tests in `src/tests/test-world.js` for region cache — keep for write path, add new test for chunk-level read
+- Manual verification: open browser, enable `CHUNK_PERF_DEBUG`, observe `runtime-chunk-record-db` drops from ~1000ms to <50ms

为 chunk 装载路径添加细粒度性能监控，覆盖主线程与 Worker 端各阶段耗时，
支持按 chunk 聚合的性能报告输出，便于定位装载瓶颈。

核心变更：
- ChunkPerfMonitor 新增 aggregateChunkLoadPerf / printChunkLoadPerfReport /
  帧级耗时监控（startFrameChunkPerf / endFrameChunkPerf）
- Chunk.loadFromRecord 注入各子阶段打点（injectBlockData、staticEntities、
  entityRestore、enqueueAssembly），buildMeshesFromRecord 拆分 4 个子阶段
- Chunk._injectBlockData 添加 clear / iterate / write 细分计时
- ChunkAssemblyScheduler 记录排队延迟（queueWaitMs）与 stage 执行前后状态对比
- WorldWorker 端新增 _workerPerfPhases 返回子阶段耗时（faceCulling、
  buildBlockDataBlocks、buildScatteredBlocks、buildMeshData、buildRouting）
- World._onChunkWorkerResult 接收并透传 Worker 端子阶段打点
- GlobalInstancedMeshManager.replaceChunkVisibleBlocks / patchChunkVisibleBlocks
  添加性能记录
- World 暴露 printChunkLoadPerf / getChunkLoadPerf 供浏览器控制台调试

- 新增 MemoryWorldStore 作为运行期世界级权威内存存储
- World 启动时导入旧存档到内存，新世界生成直写内存
- chunk record 读路径优先从内存获取，回退 IndexedDB
- 方块修改立即同步到 MemoryWorldStore.applyBlockMutation
- 旁路 unload/background flush 运行期主链路
- 拆分 chunk 装配为 runtime-hydrate → runtime-build-mesh → runtime-finalize 三阶段
- GlobalInstancedMeshManager 新增 applyChunkDelta 增量 patch
- 补充性能打点：world.runtime-chunk-record-memory、global-instanced-mesh.delta-patch 等
- 新增 MemoryWorldStore 单元测试

当前状态：读路径切换和 flush 旁路已完成，但 stage 拆分仅完成
「拆分」本身，尚未实现「可中断」，接下来需要实现可中断装配

+# Runtime Memory WorldStore Authority Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** 将运行期权威数据源从 `IndexedDB` 切换为常驻内存的 `MemoryWorldStore`，并同步拆细 chunk 主线程装配与 global mesh patch，消除 chunk streaming 期间的读路径排队、后台 flush 竞争和 8~12ms 级主线程长任务。
+
+**Architecture:** 运行期采用“`MemoryWorldStore` 世界级权威层 + `Chunk Working Set` 热数据层”双层模型。旧存档只在启动时一次性导入内存，新世界生成结果直接写入内存权威层；运行期间所有方块修改先改 `chunk.blockData`，再立即同步到 `MemoryWorldStore`，完全切断 `IndexedDB` 对 chunk streaming 的参与。装配链路改成细粒度 stage，运行期 patch 改成增量 delta。
+
+**Tech Stack:** JavaScript, Three.js, Web Workers, IndexedDB, 浏览器内测试页面, ESLint
+

+
+## 文件结构与职责
+
+### 新增文件
+
+- `src/world/MemoryWorldStore.js`
+  - 运行期世界级权威内存存储
+  - 管理 `region/chunkRecord`、dirty/version/stats
+- `src/tests/test-memory-world-store.js`
+  - `MemoryWorldStore` 单元测试
+
+### 重点修改文件
+
+- `src/world/World.js`
+  - 世界启动流程接入内存权威层
+  - chunk record 请求改为内存读路径
+- `src/world/WorldRuntime.js`
+  - 从“写回协调器”转为“内存工作集协调器”
+  - 旁路 unload/background flush 主链路
+- `src/world/WorldStore.js`
+  - 降级为导入/导出工具，而不是运行期权威接口
+- `src/world/Chunk.js`
+  - block mutation 立即同步 `MemoryWorldStore`
+  - `loadFromRecord` 拆分为更细粒度的运行期装配阶段
+- `src/world/ChunkAssemblyScheduler.js`
+  - 扩展更细粒度 stage
+- `src/core/GlobalInstancedMeshManager.js`
+  - 增加 chunk delta patch 接口，区分首次加载和运行期增量 patch
+- `src/tests/test-world-runtime.js`
+  - 更新运行时缓存与 flush 语义测试
+- `src/tests/test-world.js`
+  - 更新世界启动/加载路径测试
+- `src/tests/test-chunk.js`
+  - 更新 block mutation 同步权威层测试
+- `src/tests/test-global-instanced-mesh-manager.js`
+  - 增加增量 patch 测试

+
+### Task 1: 建立 `MemoryWorldStore` 权威内存层
+
+**Files:**
+- Create: `src/world/MemoryWorldStore.js`
+- Test: `src/tests/test-memory-world-store.js`
+
+- [ ] **Step 1: 写一个失败的测试，定义 `MemoryWorldStore` 的最小接口**
+
+在 `src/tests/test-memory-world-store.js` 新增测试，至少覆盖：
+
+- `createOrReplaceChunkRecord(cx, cz, record)` 可写入 chunk
+- `getChunkRecord(cx, cz)` 可读回 chunk
+- `applyBlockMutation(cx, cz, coord, entry)` 可立即更新权威 `blockData`
+- `getStats()` 返回 region/chunk 计数
+
+示例断言：
+
+```js
+test('applyBlockMutation 应立即更新 chunkRecord.blockData', () => {
+  const store = new MemoryWorldStore();
+  store.createOrReplaceChunkRecord(1, 2, { blockData: {}, staticEntities: [], runtimeSeedData: {}, runtimeEntities: {} });
+  store.applyBlockMutation(1, 2, 123, 'stone');
+  const record = store.getChunkRecord(1, 2);
+  assertEqual(record.blockData[123], 'stone');
+});
+```
+
+- [ ] **Step 2: 运行测试确认失败**
+
+Run: 打开 `http://localhost:8080/src/tests/index.html`，运行新增测试  
+Expected: `MemoryWorldStore` 未定义或接口缺失导致失败
+
+- [ ] **Step 3: 实现 `MemoryWorldStore` 最小版本**
+
+在 `src/world/MemoryWorldStore.js` 实现：
+
+- region/chunk 双索引
+- `chunkKey` / `regionKey` 工具方法
+- `createOrReplaceChunkRecord`
+- `getChunkRecord`
+- `applyBlockMutation`
+- `getStats`
+
+先沿用对象版 `blockData`，不要第一步就做 TypedArray 压缩。
+
+- [ ] **Step 4: 让测试通过**
+
+Run: 打开测试页，运行新增测试

+### Task 2: 世界启动时接入全量内存导入与生成直写
+
+**Files:**
+- Modify: `src/world/World.js`
+- Modify: `src/world/WorldStore.js`
+- Modify: `src/world/WorldRuntime.js`
+- Test: `src/tests/test-world.js`
+- Test: `src/tests/test-world-runtime.js`
+
+- [ ] **Step 1: 写失败测试，定义“运行期 chunk record 从内存获取”**
+
+为 `World` / `WorldRuntime` 增加测试，验证：
+
+- `World` 启动后持有 `memoryWorldStore`
+- `_requestRuntimeChunkRecord()` 优先从内存权威层读取
+- 不再调用 `WorldStore.getChunkRecord()` 作为运行期主路径
+
+示例断言：
+
+```js
+assertEqual(memoryStoreCalls.getChunkRecord.length, 1);
+assertEqual(worldStoreCalls.getChunkRecord.length, 0);
+```
+
+- [ ] **Step 2: 写失败测试，定义“新世界生成结果直接写入内存权威层”**
+
+为生成链路增加测试，验证：
+
+- 世界生成后的 chunkRecord 直接进入 `MemoryWorldStore`
+- 不触发 `PersistenceService.saveRegionRecord/saveChunkData`
+
+- [ ] **Step 3: 在 `World` 中注入 `MemoryWorldStore`**
+
+在 `src/world/World.js`：
+
+- 构造阶段创建 `this.memoryWorldStore`
+- 启动流程中增加“旧存档全量导入内存”入口
+- 新世界生成完成后直接写入 `MemoryWorldStore`
+
+- [ ] **Step 4: 让 `WorldRuntime.ensureChunkData()` 改从内存读**
+
+在 `src/world/WorldRuntime.js`：
+
+- 新增对 `memoryWorldStore.getChunkRecord()` 的使用
+- `ensureChunkData()` 返回 `{ status: 'ready', chunkRecord }`
+- 不再把运行期读取落到 `WorldStore.getChunkRecord()`
+
+- [ ] **Step 5: 将 `WorldStore` 降级为导入/导出工具**
+
+在 `src/world/WorldStore.js`：
+
+- 保留旧的 `getRegionRecord/saveRegionRecord/...` 供导入导出用
+- 明确注释：运行期主链路不应直接用它取 chunk record
+
+- [ ] **Step 6: 补一个运行期性能打点名字迁移**
+
+把 `world.runtime-chunk-record-db` 改成新的内存读路径打点，例如：
+
+```js
+recordChunkPerf('world.runtime-chunk-record-memory', ...);
+```
+
+并确保不再出现 `-db` 命名。
+
+- [ ] **Step 7: 跑测试确认通过**
+
+Run: 打开测试页，运行 `test-world.js`、`test-world-runtime.js`  
+Expected: 启动/读取相关测试通过
+
+- [ ] **Step 8: 运行 lint**
+
+Run: `npm run lint`  
+Expected: 无新增 lint 错误
+
+- [ ] **Step 9: 提交这一小步改动**
+
+```bash
+git add src/world/World.js src/world/WorldStore.js src/world/WorldRuntime.js src/tests/test-world.js src/tests/test-world-runtime.js

+### Task 3: 方块修改立即同步到内存权威层
+
+**Files:**
+- Modify: `src/world/Chunk.js`
+- Modify: `src/world/WorldRuntime.js`
+- Test: `src/tests/test-chunk.js`
+
+- [ ] **Step 1: 写失败测试，定义 block mutation 的立即同步语义**
+
+在 `src/tests/test-chunk.js` 增加测试，覆盖：
+
+- `addBlockDynamic()` 修改后，`MemoryWorldStore` 中对应 `blockData` 同步更新
+- `removeBlockDynamic()` 删除后，权威层对应 entry 被删除
+- 批量删除路径也会同步到权威层
+
+- [ ] **Step 2: 在 `Chunk` 中接入 `MemoryWorldStore.applyBlockMutation`**
+
+在 `src/world/Chunk.js` 的动态增删改路径中：
+
+- 先改 `chunk.blockData`
+- 同一调用栈内同步调用 `memoryWorldStore.applyBlockMutation(...)`
+- 不再依赖 unload flush 才成为真相
+
+- [ ] **Step 3: 清理 `WorldRuntime` 的“运行期正确性依赖 flush”语义**
+
+在 `src/world/WorldRuntime.js` 中：
+
+- 保留 `dirty/version` 仅用于未来手动保存
+- 去掉“必须 flush 才有权威正确性”的假设
+
+- [ ] **Step 4: 测试验证通过**
+
+Run: 打开测试页，运行 `test-chunk.js`  
+Expected: 新增 block mutation 权威同步测试通过
+
+- [ ] **Step 5: 运行 lint**
+
+Run: `npm run lint`  
+Expected: 无新增 lint 错误
+
+- [ ] **Step 6: 提交这一小步改动**
+
+```bash
+git add src/world/Chunk.js src/world/WorldRuntime.js src/tests/test-chunk.js
+git commit -m "refactor: sync chunk mutations to memory authority immediately"
+```
+

+
+### Task 4: 旁路 unload/background flush 运行期主链路
+
+**Files:**
+- Modify: `src/world/WorldRuntime.js`
+- Modify: `src/world/World.js`
+- Test: `src/tests/test-world-runtime.js`
+
+- [ ] **Step 1: 写失败测试，定义“chunk 卸载只释放渲染资源，不再承担保存正确性”**
+
+新增测试覆盖：
+
+- chunk unload 后不再进入 `pendingUnloadFlushQueue`
+- 运行时不再记录 `world-runtime.background-flush`
+- 卸载后重载仍从 `MemoryWorldStore` 恢复数据
+
+- [ ] **Step 2: 旁路 `pendingUnloadFlushQueue` 与 flush 入口**
+
+在 `src/world/WorldRuntime.js`：
+
+- 让 `flushBeforeUnload`
+- `flushChunk`
+- `flushAllDirty`
+- `flushPendingUnloadQueueWithinBudget`
+
+退出运行期主链路，最简单可先改成：
+
+- 不再被 `World.update()` 驱动
+- 仅保留兼容壳或显式注释弃用
+
+- [ ] **Step 3: 清理 `World` 中 idle task 对 unload flush 的调度**
+
+在 `src/world/World.js`：
+
+- 移除 `unload-flush-queue` idle task 的运行期调度
+- 保留未来手动保存所需的扩展位，但不在当前 session 自动执行
+
+- [ ] **Step 4: 验证测试通过**
+
+Run: 打开测试页，运行 `test-world-runtime.js`  
+Expected: 卸载/重载相关测试通过
+
+- [ ] **Step 5: 运行 lint**
+
+Run: `npm run lint`  
+Expected: 无新增 lint 错误
+
+- [ ] **Step 6: 提交这一小步改动**
+
+```bash
+git add src/world/WorldRuntime.js src/world/World.js src/tests/test-world-runtime.js
+git commit -m "refactor: bypass runtime unload flush path"
+```
+

+
+### Task 5: 拆细 chunk 主线程装配 stage
+
+**Files:**
+- Modify: `src/world/Chunk.js`
+- Modify: `src/world/ChunkAssemblyScheduler.js`
+- Test: `src/tests/test-chunk.js`
+- Test: `src/tests/test-world.js`
+
+- [ ] **Step 1: 写失败测试，定义新的装配阶段流转**
+
+测试至少验证：
+
+- `loadFromMemoryRecord()` 只负责接收 record 和 enqueue
+- scheduler 会按顺序跑：
+  - `hydrate`
+  - `rebuild-indices`
+  - `collect-blocks`
+  - `convert-mesh`
+  - `prepare-visible`
+  - `enqueue-mesh`
+  - `finalize-minimal`
+
+- [ ] **Step 2: 为 `Chunk` 拆出阶段函数**
+
+在 `src/world/Chunk.js` 中新增小函数，例如：
+
+- `assembleHydratePhase()`
+- `assembleRebuildIndicesPhase()`
+- `assembleCollectBlocksPhase()`
+- `assembleConvertMeshPhase()`
+- `assemblePrepareVisiblePhase()`
+- `assembleEnqueueMeshPhase()`
+- `finalizeMinimalPhase()`
+
+要求：
+
+- 每个函数责任单一
+- 不在一个函数里混入多个重活
+
+- [ ] **Step 3: 扩展 `ChunkAssemblyScheduler` 的 stage 状态机**
+
+在 `src/world/ChunkAssemblyScheduler.js`：
+
+- 添加上述新 stage
+- 每个 stage 完成后 enqueue 下一个 stage
+- 保留现有 `terrain/entities/finalize` 旧路径的兼容逻辑，避免引爆非运行期路径
+
+- [ ] **Step 4: 让运行期路径改用新的 stage**
+
+在 `src/world/Chunk.js` / `src/world/World.js`：
+
+- `loadFromMemoryRecord()` 入队新 stage
+- 旧 `runtime-build` 不再承载全部运行期装配工作
+
+- [ ] **Step 5: 测试验证通过**
+
+Run: 打开测试页，运行 `test-chunk.js`、`test-world.js`  
+Expected: 新阶段流转测试通过，旧行为不回归
+
+- [ ] **Step 6: 运行 lint**
+
+Run: `npm run lint`  
+Expected: 无新增 lint 错误
+
+- [ ] **Step 7: 提交这一小步改动**
+
+```bash
+git add src/world/Chunk.js src/world/ChunkAssemblyScheduler.js src/tests/test-chunk.js src/tests/test-world.js
+git commit -m "perf: split runtime chunk assembly into fine-grained stages"
+```

+
+### Task 6: 将 global mesh patch 改为 chunk delta
+
+**Files:**
+- Modify: `src/world/Chunk.js`
+- Modify: `src/core/GlobalInstancedMeshManager.js`
+- Modify: `src/world/World.js`
+- Test: `src/tests/test-global-instanced-mesh-manager.js`
+
+- [ ] **Step 1: 写失败测试，定义增量 patch 行为**
+
+新增测试覆盖：
+
+- 首次 chunk 加载仍走 `replaceChunkVisibleBlocks`
+- 运行期修改走 `applyChunkDelta`
+- 增量 patch 只处理新增/删除/更新坐标，不扫描全量 chunk 可见集
+
+- [ ] **Step 2: 在 `Chunk` 中维护 render delta**
+
+在 `src/world/Chunk.js` 中为运行期修改路径维护：
+
+- `addedCoords`
+- `removedCoords`
+- `updatedCoords`
+
+并在适当时机归并/清空这些集合。
+
+- [ ] **Step 3: 在 `GlobalInstancedMeshManager` 中新增 `applyChunkDelta`**
+
+在 `src/core/GlobalInstancedMeshManager.js` 实现：
+
+- 只消费 delta
+- 分别处理 add/update/remove
+- 避免再以 `instanceIndexMap` 为核心做全量比较
+
+- [ ] **Step 4: 在 `World` 更新循环中接入 delta patch 预算**
+
+在 `src/world/World.js`：
+
+- 让运行期 chunk 修改优先走 delta patch
+- 为 delta patch 也设定单帧预算
+
+- [ ] **Step 5: 测试验证通过**
+
+Run: 打开测试页，运行 `test-global-instanced-mesh-manager.js`  
+Expected: 增量 patch 测试通过
+
+- [ ] **Step 6: 运行 lint**
+
+Run: `npm run lint`  
+Expected: 无新增 lint 错误
+
+- [ ] **Step 7: 提交这一小步改动**
+
+```bash

+- Modify: `src/utils/ChunkPerfMonitor.js`
+- Modify: `src/world/World.js`
+- Modify: `src/world/WorldRuntime.js`
+- Test: `src/tests/test-chunk-perf-monitor.js`
+
+- [ ] **Step 1: 写失败测试，定义新的关键打点名称**
+
+至少覆盖：
+
+- `world.runtime-chunk-record-memory`
+- `memory-worldstore.hit/miss`
+- `global-instanced-mesh.delta-patch`
+
+- [ ] **Step 2: 为内存权威层和 delta patch 加打点**
+
+在相关模块中增加新 perf label，便于区分：
+
+- 内存读是否命中
+- stage 是否仍超预算
+- delta patch 是否仍有峰值
+
+- [ ] **Step 3: 更新或新增 perf monitor 测试**
+
+确保新 label 不会破坏既有报告逻辑。
+
+- [ ] **Step 4: 运行浏览器内回归测试**
+
+Run:
+- 打开 `http://localhost:8080/src/tests/index.html`
+- 点击“运行所有测试”
+
+Expected:
+- 所有自动测试通过
+
+- [ ] **Step 5: 运行 lint**
+
+Run: `npm run lint`  
+Expected: 无新增 lint 错误
+
+- [ ] **Step 6: 做一次手工性能验证**
+
+手工验证项：
+
+- 进入世界后跑图一段时间
+- 控制台确认不再出现 `world.runtime-chunk-record-db`
+- 控制台确认不再出现 `world-runtime.background-flush`
+- 观察 `chunk-assembly.task` 是否明显减少 8ms+ 尖峰
+- 观察 `global-instanced-mesh.patch-chunk` 是否被新的 delta patch 指标替代
+
+- [ ] **Step 7: 提交这一小步改动**
+
+```bash
+git add src/utils/ChunkPerfMonitor.js src/world/World.js src/world/WorldRuntime.js src/tests/test-chunk-perf-monitor.js
+git commit -m "chore: add runtime memory authority perf metrics"
+```
+

+
+## 执行注意事项
+
+- 先不要实现手动保存
+- 先不要引入新的压缩格式
+- 先让主链路正确、稳定、可观测
+- 如果某步发现世界规模导致内存占用超预期，先补统计，不要提前做激进压缩重构
+- 每完成一个 Task，都重新跑对应测试与 `npm run lint`
+
+## 最终验收标准
+
+- 运行期 chunk streaming 不再回源 `IndexedDB`
+- chunk 卸载不再触发后台保存竞争
+- 方块修改会立即同步到内存权威层
+- chunk 装配阶段被拆细，单个 stage 峰值显著下降
+- 运行期 mesh 更新改为增量 delta
+- 浏览器内测试通过，lint 通过

+# Runtime Memory WorldStore Authority Design
+
+> **Problem:** 运行期 chunk 加载当前仍依赖 `IndexedDB` / `PersistenceWorker` 读取权威 `ChunkRecord`，并且后台 unload flush、region patch、chunk 主线程装配、global instanced mesh patch 互相耦合，导致读路径排队、主线程长任务和帧尖峰叠加，无法稳定达到 60fps。
+
+## 1. Goal
+
+将运行期权威数据源从 `IndexedDB` 迁移到常驻内存的 `IndexedDB_Memory_Storage`，并围绕这一变更清理三条高成本链路：
+
+1. 去掉运行期 chunk load 对 `IndexedDB` 的依赖
+2. 将 chunk 主线程装配拆成更细粒度的 stage
+3. 将 global instanced mesh patch 从全量比较改为增量 patch
+
+本设计明确接受以下取舍：
+
+- 启动/读档可以更慢
+- 运行期不考虑异常崩溃后的进度丢失
+- 自动持久化不是当前目标
+- 未来仅通过手动保存功能将内存权威层导出到 `IndexedDB`
+
+## 2. Non-Goals
+
+- 本次不实现手动保存 UI 或导出流程
+- 本次不重做世界生成算法
+- 本次不要求第一阶段就把全部权威数据结构 TypedArray 化
+- 本次不解决所有渲染性能问题，只聚焦 chunk streaming 主链路
+
+## 3. Current Root Cause
+
+### 3.1 运行期读取与写回竞争
+
+当前 [src/world/World.js](/Users/bachi/jaylli/mc-lite/src/world/World.js:308) 中 `_requestRuntimeChunkRecord()` 通过 `WorldRuntime.ensureChunkData()` 读取权威 chunk record，并记录 `world.runtime-chunk-record-db`。
+
+读取路径最终落到：
+
+- [src/world/WorldStore.js](/Users/bachi/jaylli/mc-lite/src/world/WorldStore.js:136) `getChunkRecord`
+- [src/workers/PersistenceWorker.js](/Users/bachi/jaylli/mc-lite/src/workers/PersistenceWorker.js:165) `getChunkRecord`
+
+同时 unload/background flush 路径仍然会在运行期触发：
+
+- [src/world/WorldRuntime.js](/Users/bachi/jaylli/mc-lite/src/world/WorldRuntime.js:584) `_flushPendingUnloadQueueWithinBudgetInternal`
+- [src/workers/PersistenceWorker.js](/Users/bachi/jaylli/mc-lite/src/workers/PersistenceWorker.js:229) `applyRegionPatch`
+
+结果是同一个 `PersistenceWorker` 同时承担：
+
+- 运行期 chunk record 读取
+- region patch / saveRegionRecord 写回
+- worker 内 region cache 仲裁
+
+这会把后台写压力传导到前台读路径。
+
+### 3.2 Chunk 主线程装配过粗
+
+[src/world/Chunk.js](/Users/bachi/jaylli/mc-lite/src/world/Chunk.js:284) `loadFromRecord()` 在逻辑上虽然把装配交给了 scheduler，但当前 `runtime-build` 阶段仍然打包了以下重活：
+
+- `_injectBlockData()`
+- `_buildMeshFromExistingBlockData()`
+- `buildMeshes()`
+
+[src/world/ChunkAssemblyScheduler.js](/Users/bachi/jaylli/mc-lite/src/world/ChunkAssemblyScheduler.js:127) 的 `runtime-build` stage 不可中断，所以单个 task 仍可跑到 8~12ms。
+
+### 3.3 Global Instanced Mesh Patch 仍做全量比较
+
+[src/core/GlobalInstancedMeshManager.js](/Users/bachi/jaylli/mc-lite/src/core/GlobalInstancedMeshManager.js:393) `patchChunkVisibleBlocks()` 每次 patch 都会：
+
+- 遍历整份 `instanceIndexMap`
+- 构造 `Set`
+- 做 update/add/remove 三类混合处理
+- 对已有 coords 做全量比较删除
+
+这导致 patch 可以单次达到 10ms+。
+
+## 4. Proposed Architecture
+
+### 4.1 Runtime Authority Layers
+
+新的运行期数据层分为两层：
+
+1. **`IndexedDB_Memory_Storage` / `MemoryWorldStore`**
+   - 整个已生成世界的唯一权威数据源
+   - 启动时一次性全量导入旧世界，或由生成器直接写入
+   - 运行期间只在内存中读写
+   - 不自动回写 `IndexedDB`
+
+2. **`Chunk Working Set`**
+   - 当前已加载 chunk 的热数据视图
+   - 以 `chunk.blockData` 为逻辑入口
+   - 挂载逻辑/渲染派生缓存：
+     - `blockDataArray`
+     - `solidBlocks`
+     - `solidBlockIds`
+     - `lightSourceCoords`
+     - `visibleKeys`
+     - 增量 render delta
+
+关系如下：
+
+```text
+MemoryWorldStore (唯一真相)
+  -> Chunk.loadFromMemoryRecord()
+    -> Chunk Working Set
+      -> 渲染 / 碰撞 / 交互
+
+Chunk Working Set mutation
+  -> 同步 apply 到 MemoryWorldStore
+```
+
+### 4.2 New Data Sources
+
+运行期只允许两种权威数据进入 `MemoryWorldStore`：
+
+1. **旧存档读档**
+   - `IndexedDB -> MemoryWorldStore.importAll()`
+2. **新世界生成**
+   - `World generation -> MemoryWorldStore.createOrReplaceChunkRecord()`
+
+一旦进入 session：
+
+- `MemoryWorldStore` 成为唯一真相
+- `Chunk` 不再从 `IndexedDB` 读取
+- `Chunk` 卸载不再触发保存正确性的后台回写
+
+## 5. Memory Data Model
+
+### 5.1 First-Phase Structure
+
+第一阶段先保持语义稳定，不立刻做激进压缩：
+
+```js
+class MemoryWorldStore {
+  worldMeta;
+  regions;     // Map<regionKey, MemoryRegionRecord>
+  chunks;      // Map<chunkKey, MemoryChunkRecord>
+  dirtyChunks; // Set<chunkKey>
+  stats;
+}
+
+class MemoryRegionRecord {
+  regionKey;
+  rx;
+  rz;
+  chunkKeys;
+  chunks;
+  generatedAt;
+  generatorVersion;
+}
+
+class MemoryChunkRecord {
+  chunkKey;
+  cx;
+  cz;
+  blockData;
+  staticEntities;
+  runtimeSeedData;
+  runtimeEntities;
+  version;
+  dirty;
+  lastModifiedAt;
+}
+```
+
+其中 `blockData` 第一阶段仍可沿用当前对象格式 `{ [encodedCoord]: entry }`，以降低迁移成本并复用现有 `ChunkRecord` 语义。
+
+### 5.2 Second-Phase Upgrade Path
+
+等运行期链路稳定后，再考虑：
+
+- `blockData` 改为稠密层 + 稀疏层
+- 活跃 chunk working set 优先 TypedArray 化
+- 权威层保留对象版或做延后压缩
+
+本次设计不把 TypedArray 化作为前置条件。
+
+## 6. Read / Write Semantics
+
+### 6.1 Read Path
+
+运行期 chunk 加载路径改成：
+
+```text
+World
+  -> MemoryWorldStore.getChunkRecord(chunkKey)
+  -> Chunk.loadFromMemoryRecord(record)
+  -> ChunkAssemblyScheduler enqueue fine-grained stages
+```
+
+运行期不允许出现：
+
+- `world.runtime-chunk-record-db`
+- chunk load 回源 `WorldStore.getChunkRecord()`
+- `PersistenceWorker` 参与 chunk streaming
+
+### 6.2 Write Path
+
+你已明确要求 `chunk.blockData` 改动后立即同步到权威层，因此规则固定为：
+
+1. 所有方块修改先改 `chunk.blockData`
+2. 同一调用栈内立即调用 `MemoryWorldStore.applyBlockMutation(...)`
+3. 渲染/AO/face culling patch 继续由 `Chunk` 自己负责
+
+这意味着：
+
+- `dirty` 不再服务运行期正确性
+- `dirty` 只为未来手动保存准备
+- 卸载 chunk 时不需要再“补写真相”
+
+## 7. Component Changes
+
+### 7.1 `MemoryWorldStore`
+
+新增 `src/world/MemoryWorldStore.js`，负责：
+
+- 全量导入旧存档到内存
+- 接收新世界生成结果
+- 提供 chunk 级快速索引
+- 记录 dirty/version/stats
+- 提供 block mutation API
+
+建议核心 API：
+
+- `importAllFromPersistence()`
+- `createOrReplaceChunkRecord(chunkKey, chunkRecord)`
+- `getChunkRecord(cx, cz)`
+- `getRegion(rx, rz)`
+- `applyBlockMutation(cx, cz, coord, entry)`
+- `applyChunkBlockSnapshot(cx, cz, blockData)`
+- `getStats()`
+
+### 7.2 `WorldRuntime`
+
+`WorldRuntime` 从“回写协调器”改为“内存工作集协调器”。
+
+下线或旁路的职责：
+
+- `pendingUnloadFlushQueue`
+- `flushChunk`
+- `flushAllDirty`
+- `flushBeforeUnload`
+- `background-flush`
+
+保留职责：
+
+- chunk 生命周期
+- 运行时 region/chunk 索引
+- 预取/边界逻辑
+- 活跃 chunk 与权威内存层的协调
+
+### 7.3 `WorldStore`
+
+`WorldStore` 从“运行期权威接口”降级为：
+
+- 旧存档导入工具
+- 未来手动保存导出工具
+
+运行期主链路不再直接依赖它。
+
+### 7.4 `Chunk`
+
+`Chunk` 继续承担活跃 chunk 的热数据结构和局部渲染逻辑，但不再承担“卸载前回写持久化”的职责。
+
+需要改造的重点：
+
+- 提供 `loadFromMemoryRecord()`
+- 将 block mutation 同步到 `MemoryWorldStore`
+- 拆细运行期装配 stage
+- 维护 render delta
+
+## 8. Chunk Assembly Refactor
+
+### 8.1 Target
+
+目标不是减少阶段数，而是压低单阶段峰值：
+
+- 单个 stage 尽量控制在 2~4ms
+- 避免任何单 task 长时间阻塞主线程
+
+### 8.2 Proposed Stages
+
+将当前粗粒度 `runtime-build` 拆成：
+
+1. `hydrate`
+   - 接收 `MemoryChunkRecord`
+   - 绑定最小上下文
+
+2. `rebuild-indices`
+   - 重建 `solidBlocks`、`lightSourceCoords`、`blockDataArray`
+
+3. `collect-blocks`
+   - 从 `blockData` 收集 `blocks[]`
+
+4. `convert-mesh`
+   - 转成 mesh groups / AO / orientation 数据
+
+5. `prepare-visible`
+   - 构建 `visibleKeys`
+
+6. `enqueue-mesh`
+   - 将数据推入 global manager 队列
+
+7. `finalize-minimal`
+   - 仅做 `isReady/loadState` 切换
+
+8. `deferred-finalize`
+   - 光源注册
+   - AO stable refresh
+   - 运行时实体恢复
+
+### 8.3 Stage Discipline
+
+- `Chunk.loadFromMemoryRecord()` 只做 record 接收和调度入队
+- 重活都放到 scheduler 的细粒度 stage
+- `finalize-minimal` 必须保持极轻
+
+## 9. Global Instanced Mesh Patch Refactor
+
+### 9.1 Problem
+
+现状中 patch 基于“全量可见集合对比”，导致：
+
+- `Object.entries(instanceIndexMap)`
+- `Set`
+- `Array.from(existingCoords)`
+- update/add/remove 混合处理
+
+### 9.2 Proposed Delta Model
+
+让 `Chunk` 维护自己的渲染增量：
+
+- `addedCoords`
+- `removedCoords`
+- `updatedCoords`
+
+新增接口：
+
+- `GlobalInstancedMeshManager.applyChunkDelta(chunkKey, delta)`
+
+路径区分为：
+
+1. 首次 chunk 加载
+   - 走 `replaceChunkVisibleBlocks`
+2. 运行期方块修改
+   - 走 `applyChunkDelta`
+
+### 9.3 Budgeting
+
+增量 patch 同样纳入帧预算：
+
+- 限制单帧 patch 块数
+- 限制单帧 patch ms
+- 与现有 `flushMutationQueue` 预算模型对齐
+
+## 10. Migration Strategy
+
+### Phase 1
+
+先引入 `MemoryWorldStore`，切断运行期 DB 权威性，但暂时保留旧持久化代码供导入使用。
+
+### Phase 2
+
+将 `Chunk` 的 block mutation 立即同步到 `MemoryWorldStore`，去掉 unload flush 正确性依赖。
+
+### Phase 3
+
+拆细 chunk assembly stage，消除 8~12ms 主线程任务。
+
+### Phase 4
+
+实现 global mesh 增量 patch，削掉 10ms+ patch 尖峰。
+
+### Phase 5
+
+再做 GC/内存压缩优化。
+
+## 11. Observability
+
+本次改造后，建议补充以下运行期指标：
+
+- `world.runtime-chunk-record-memory`
+- `memory-worldstore.hit/miss`
+- `memory-worldstore.world-size`
+- `chunk-assembly.stage.*`
+- `global-instanced-mesh.delta-patch`
+- `chunk.block-mutation.sync-memory`
+
+目标是能清楚区分：
+
+- 权威层读取是否还在卡
+- 主线程装配是否仍有超预算阶段
+- patch 是否还有局部峰值
+
+## 12. Expected Outcome
+
+如果该设计完整落地，运行期应具备以下特征：
+
+- chunk load 不再等待 `IndexedDB`
+- chunk unload 不再触发后台写回竞争
+- `PersistenceWorker` 不再参与 streaming 主链路
+- `ChunkAssemblyScheduler` 不再存在 8~12ms 的粗任务
+- global mesh patch 不再依赖全量集合比较
+- 运行期权威链路收敛为：
+
+```text
+MemoryWorldStore
+  -> Chunk Working Set
+    -> Render Delta
+```
+
+## 13. Risks
+
+1. 全世界一次性载入内存会增加启动时间与 RAM 占用
+2. 如果仍有旧路径直接改 `chunk.blockData` 而不改权威层，会造成双份状态漂移
+3. stage 拆细后需要更严格的 chunk 生命周期状态机
+4. 增量 patch 若漏清理 delta，会出现渲染残影或重复实例
+
+这些风险都可接受，因为它们比当前“运行期掉帧”更容易被观测和修正。

将 runtime-hydrate 和 runtime-build-mesh 两个 stage 改为可中断的分批执行模式，
确保单个 stage 耗时不超过 scheduler 预算（~3ms），避免帧卡顿。

核心改动：
- Chunk 新增 _assemblyProgress 游标状态，支持跨 scheduler 调用恢复执行
- 新增 _clearForBlockInjection / _injectBlockDataBatch 分批注入 blockData
- 新增 _buildMeshFromExistingBlockDataIncremental 状态机（iterate → convert-group → visible → build-mesh）
- 静态 _computeTransformMatrix 内联计算变换矩阵，避免 per-block 的 THREE.Object3D 开销
- Scheduler 处理 'continue'/'done' 返回值，实现 stage 重新入队或推进到下一阶段
- 新增 chunk.inject-block-data.partial / chunk.build-mesh-increment.partial 性能打点

旧版同步方法（_loadFromCachedRecord / _buildMeshFromExistingBlockData）保留不变，
供非 scheduler 场景（测试/首屏生成）使用。

WorldWorker 在 bootstrap 阶段生成的 AO 数据不会被存入 MemoryWorldStore 权威数据源，
且在 finalize 阶段会被 _refreshAOFromStableSource → AOWorker 全量重算并覆写。
将 Worker 侧 AO 计算替换为常量 aoLow/aoHigh=1，减少 bootstrap 阶段的每方块 6 方向遮挡查询。

+# Bootstrap 阶段跳过 AO 计算 Implementation Plan
+
+> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
+
+**Goal:** 在 WorldWorker 生成阶段跳过不必要的 `calculateAOForBlock()` 调用，将 aoLow/aoHigh 设为常量 1，减少 bootstrap 阶段的 Worker 计算耗时。
+
+**Architecture:** WorldWorker 生成的 AO 数据在 bootstrap finalize 阶段会被 `_refreshAOFromStableSource` → AOWorker 全量重算并覆写 InstancedMesh AO attribute。因此 Worker 侧的 AO 计算是冗余的——它既不会被存入 MemoryWorldStore 权威数据源，也不会被 runtime 路径复用。改动集中在一处：将 AO 计算结果替换为常量，保留数据结构不变以维持下游兼容。
+
+**Tech Stack:** Vanilla JS (ES Modules), Three.js 0.160.0, Web Workers
+
+---
+
+### Task 1: 替换 Worker 侧 AO 计算为常量
+
+**Files:**
+- Modify: `src/workers/WorldWorker.js:2863-2872`
+
+**Step 1: 修改 WorldWorker.js 中的 AO 计算逻辑**
+
+将第 2863-2872 行的 AO 计算块：
+
+```js
+      let aoLow = 0;
+      let aoHigh = 0;
+      // 简化AO逻辑：非透明且实心的方块自动启用AO
+      const isAOEnabled = !props.isTransparent && props.isSolid;
+      if (isAOEnabled) {
+        ({ aoLow, aoHigh } = calculateAOForBlock(block.x, block.y, block.z, isOccluding));
+      }
+      d[block.type].push({x: block.x, y: block.y, z: block.z, aoLow, aoHigh, orientation: block.orientation || 0});
+      visibleKeysSet.add(key);
+      aoMap.set(key, { aoLow, aoHigh });
+```
+
+改为：
+
+```js
+      // AO 计算已移至 _refreshAOFromStableSource（AOWorker），bootstrap 阶段跳过
+      const aoLow = 1;
+      const aoHigh = 1;
+      d[block.type].push({x: block.x, y: block.y, z: block.z, aoLow, aoHigh, orientation: block.orientation || 0});
+      visibleKeysSet.add(key);
+      aoMap.set(key, { aoLow, aoHigh });
+```
+
+保留数据结构不变（`aoLow`/`aoHigh` 字段仍然存在，值恒为 1，确保 `buildScatteredBlocks` 和 `buildMeshData` 无需改动）。
+
+**Step 2: 运行 lint 检查**
+
+```bash
+npm run lint
+```
+
+Expected: 无新增警告（`calculateAOForBlock` import 若变为未使用，则移除该 import）。
+
+**Step 3: 运行全量测试**
+
+```bash
+node command/run-tests.js
+```
+
+Expected: 所有测试通过（AO 计算变化不影响 blockData 正确性、面剔除结果和碰撞逻辑）。
+
+**Step 4: 手动验证（可选）**
+
+启动 `npm run start`，观察：
+- Bootstrap 阶段 chunk 是否能正常显示（flat 光照）
+- 进入 runtime 后 AO 阴影是否正确出现
+- 控制台有无异常错误
+
+---
+
+### Task 2: 清理未使用的 import（如需要）
+
+**Files:**
+- Modify: `src/workers/WorldWorker.js:19`
+
+**Step 1: 检查 `calculateAOForBlock` 是否还有其他调用**
+
+```bash
+grep -n "calculateAOForBlock" src/workers/WorldWorker.js
+```
+
+如果只剩 import 行而无调用处，则移除：
+
+```js
+// 删除这一行
+import { calculateAOForBlock } from '../utils/AOUtils.js';
+```
+
+**Step 2: 再次运行 lint 和测试确认**
+
+```bash
+npm run lint
+node command/run-tests.js
+```
+
+---
+
+### 改动总结
+
+| 文件 | 改动 | 影响 |
+|------|------|------|
+| `src/workers/WorldWorker.js` | 替换 AO 计算为常量 `aoLow=1, aoHigh=1` | Worker 回包的 scatteredBlocks/meshData 中 AO 值为常量 1 |
+| `src/workers/WorldWorker.js` | 移除 `calculateAOForBlock` import（若无其他调用） | 清理无用依赖 |
+
+**不修改的文件（说明为什么不需要改）：**
+- `src/world/Chunk.js` — `_convertScatteredBlocksToMeshData` 已支持 `aoLow ?? 1` 默认值
+- `src/world/ChunkConsolidation.js` — consolidation 路径在 runtime，需要 AO，不受影响
+- `src/world/MemoryWorldStore.js` — 已只存储 type+orientation，不存 AO
+- `src/world/WorldGenerationService.js` — 已只提取 blockData，不存 AO
+- `src/utils/AOUtils.js` — `calculateAOForBlock` 仍被 consolidation 和 AOWorker 使用
+- `src/core/AOBridge.js` / `src/workers/AOWorker.js` — 不受影响
+
+**正确性保障链：**
+> Worker flat AO → bootstrap 显示 flat 光照 → `finalizeNonDeferredPhase` → `onChunkFinalized` → `_refreshAOFromStableSource({ fullRefresh: true })` → AOWorker 计算正确 AO → 覆写 InstancedMesh AO attribute → 显示正确 AO 阴影

+# AO Refresh Hot Path Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** 将 chunk 稳定阶段的 AO 刷新从主线程全量标脏改为基于 face culling 后可见实例和边界影响带的异步 Worker 刷新，降低 `non-deferred-finalize` / deferred finalize 峰值耗时。
+
+**Architecture:** 主线程只维护 AO dirty 候选和 attribute 应用，真实 AO 计算继续由 `AOWorker` 执行。`Chunk` 侧 full refresh 改为遍历 `instanceIndexMap` / `visibleKeys`，边界刷新改为坐标生成；`AOWorker` 侧用坐标直接查 `chunkCache`，避免每次请求合并大对象。
+
+**Tech Stack:** JavaScript ES Modules, Three.js InstancedMesh, Web Workers, browser test runner
+

+
+---
+
+### Task 1: 增加 AO 热路径计时
+
+**Files:**
+- Modify: `src/world/Chunk.js`
+
+- [ ] **Step 1: 引入性能记录依赖**
+
+检查 `Chunk.js` 是否已经导入 `recordChunkPerf`。如果没有，在现有 imports 中添加：
+
+```js
+import { recordChunkPerf } from '../utils/ChunkPerfMonitor.js';
+```
+
+- [ ] **Step 2: 在 `_refreshAOFromStableSource()` 中记录 full refresh 和 fullSync 成本**
+
+将结构调整为：
+
+```js
+_refreshAOFromStableSource(options = {}) {
+  const startedAt = performance.now();
+  let markMs = 0;
+  let fullSyncMs = 0;
+
+  if (options.fullRefresh) {
+    const markStartedAt = performance.now();
+    this._markAllBlocksDirtyAO();
+    markMs = performance.now() - markStartedAt;
+  }
+
+  const syncStartedAt = performance.now();
+  aoBridge.fullSync(`${this.cx},${this.cz}`, this.blockData);
+  fullSyncMs = performance.now() - syncStartedAt;
+
+  if (this.aoRefreshTimer) {
+    clearTimeout(this.aoRefreshTimer);
+    this.aoRefreshTimer = null;
+  }
+
+  this._executeAORefresh();
+
+  recordChunkPerf('chunk.ao-refresh.source-stable', performance.now() - startedAt, {
+    chunkKey: `${this.cx},${this.cz}`,
+    fullRefresh: options.fullRefresh === true,
+    dirtyAO: this.dirtyAOPositions?.size || 0,
+    markMs,
+    fullSyncMs,
+    reason: options.reason || 'unknown'
+  });
+}
+```
+
+- [ ] **Step 3: 在 `_executeAORefresh()` 中记录 positions 收集成本**
+
+围绕 `new Set(this.dirtyAOPositions)` 和 `map(code => Chunk.decodeCoord(code))` 添加计时：
+
+```js
+const collectStartedAt = performance.now();
+const sentCodes = new Set(this.dirtyAOPositions);
+const positions = [...sentCodes].map(code => Chunk.decodeCoord(code));
+const collectPositionsMs = performance.now() - collectStartedAt;
+```
+
+在 postMessage 前记录：
+
+```js
+recordChunkPerf('chunk.ao-refresh.request', collectPositionsMs, {
+  chunkKey: `${this.cx},${this.cz}`,
+  positions: positions.length,
+  collectPositionsMs
+});
+```
+
+- [ ] **Step 4: 在 `_applyAOResults()` 中记录应用成本**
+
+函数开头：
+
+```js
+const applyStartedAt = performance.now();
+```
+
+函数结束前：
+
+```js
+recordChunkPerf('chunk.ao-refresh.apply-results', performance.now() - applyStartedAt, {
+  chunkKey: `${this.cx},${this.cz}`,
+  results: results?.length || 0,
+  sentKeys: sentKeys?.size || 0
+});
+```
+
+- [ ] **Step 5: 运行 lint**
+
+Run:
+
+```bash
+npm run lint
+```
+
+Expected: 无新增 lint 错误。
+
+---
+
+### Task 2: 修复 deferred finalize 重复 AO 刷新
+
+**Files:**
+- Modify: `src/world/Chunk.js`
+
+- [ ] **Step 1: 在 `runDeferredFinalizePhase()` 中加入本轮 AO 触发标记**
+
+在函数开始、早返回之后添加：
+
+```js
+let aoRefreshTriggeredThisPass = false;
+```
+
+- [ ] **Step 2: `_needsDeferredAOStabilization` 分支传递 reason 并设置标记**
+
+将 AO 分支改为：
+
+```js
+if (this._needsDeferredAOStabilization) {
+  this.world?.onChunkAOSourceStable?.(this, {
+    fullRefresh: true,
+    markNeighborBoundaries: true,
+    reason: 'deferred-finalize-ao-stable'
+  });
+  aoRefreshTriggeredThisPass = true;
+  this._needsDeferredAOStabilization = false;
+}
+```
+
+- [ ] **Step 3: 避免同一轮 `deferred-finalize-done` 再次全量刷新**
+
+将最终分支改为：
+
+```js
+if (!this.hasDeferredFinalizeWork && !aoRefreshTriggeredThisPass) {
+  this.world?.onChunkAOSourceStable?.(this, {
+    fullRefresh: true,
+    markNeighborBoundaries: true,
+    reason: 'deferred-finalize-done'
+  });
+}
+```
+
+- [ ] **Step 4: 运行 lint**
+
+Run:
+
+```bash
+npm run lint
+```
+
+Expected: 无新增 lint 错误。
+
+---
+
+### Task 3: fullRefresh 只标记可见 AO 实例
+
+**Files:**
+- Modify: `src/world/Chunk.js`
+
+- [ ] **Step 1: 新增 AO 类型判定 helper**
+
+在 AO 相关方法附近新增：
+
+```js
+_isAOApplicableEntry(entry) {
+  if (!entry) return false;
+  const type = typeof entry === 'string' ? entry : entry.type;
+  if (!type) return false;
+  const props = getBlockProps(type);
+  return props.isSolid && !props.isTransparent;
+}
+```
+
+- [ ] **Step 2: 新增可见实例坐标收集 helper**
+
+```js
+_collectVisibleAOInstanceCodes() {
+  const codes = new Set();
+
+  const collectFromTypeMap = (typeMap) => {
+    if (!typeMap) return;
+    const entries = typeMap instanceof Map
+      ? typeMap.keys()
+      : Object.keys(typeMap);
+    for (const codeLike of entries) {
+      codes.add(Number(codeLike));
+    }
+  };
+
+  if (this.instanceIndexMap instanceof Map) {
+    for (const typeMap of this.instanceIndexMap.values()) {
+      collectFromTypeMap(typeMap);
+    }
+  } else if (this.instanceIndexMap && typeof this.instanceIndexMap === 'object') {
+    for (const typeMap of Object.values(this.instanceIndexMap)) {
+      if (!typeMap) continue;
+      collectFromTypeMap(typeMap);
+    }
+  }
+
+  if (codes.size === 0 && this.visibleKeys?.size > 0) {
+    for (const code of this.visibleKeys) {
+      codes.add(Number(code));
+    }
+  }
+
+  return codes;
+}
+```
+
+- [ ] **Step 3: 将 `_markAllBlocksDirtyAO()` 改为优先遍历可见实例**
+
+目标实现：
+
+```js
+_markAllBlocksDirtyAO() {
+  const visibleCodes = this._collectVisibleAOInstanceCodes();
+
+  if (visibleCodes.size > 0) {
+    for (const code of visibleCodes) {
+      const entry = this.blockData.get(code);
+      if (this._isAOApplicableEntry(entry)) {
+        this.dirtyAOPositions.add(code);
+      }
+    }
+    return;
+  }
+
+  // 兼容回退：没有可见索引时保留旧行为，优先保证正确性。
+  for (const [code, entry] of this.blockData) {
+    if (this._isAOApplicableEntry(entry)) {
+      this.dirtyAOPositions.add(code);
+    }
+  }
+}
+```
+
+- [ ] **Step 4: 运行 lint**
+
+Run:
+
+```bash
+npm run lint
+```
+
+Expected: 无新增 lint 错误。
+
+---
+
+### Task 4: 边界 AO 标记改为边界带生成
+
+**Files:**
+- Modify: `src/world/Chunk.js`
+
+- [ ] **Step 1: 新增边界候选加入 helper**
+
+```js
+_addDirtyAOIfRenderable(code) {
+  const entry = this.blockData.get(code);
+  if (!this._isAOApplicableEntry(entry)) return false;
+
+  if (this.visibleKeys?.size > 0 && !this.visibleKeys.has(code)) {
+    return false;
+  }
+
+  this.dirtyAOPositions.add(code);
+  return true;
+}
+```
+
+如果发现 `visibleKeys` 在某些路径不完整，则放宽为：优先查 `instanceIndexMap`，只有两者都存在且都不包含时才过滤。
+
+- [ ] **Step 2: 替换 `_markBoundaryDirtyAO()` 的全数组扫描**
+
+将 `blockDataArray` 遍历改为根据方向生成边界带：
+
+```js
+_markBoundaryDirtyAO(neighborCx, neighborCz) {
+  const startedAt = performance.now();
+  const dx = neighborCx - this.cx;
+  const dz = neighborCz - this.cz;
+
+  const minX = this.cx * CHUNK_SIZE;
+  const maxX = minX + CHUNK_SIZE - 1;
+  const minZ = this.cz * CHUNK_SIZE;
+  const maxZ = minZ + CHUNK_SIZE - 1;
+  const minY = this.worldY;
+  const maxY = this.worldY + CHUNK_SIZE - 1;
+
+  const xValues = [];
+  const zValues = [];
+
+  if (dx === 1) xValues.push(maxX, maxX - 1);
+  else if (dx === -1) xValues.push(minX, minX + 1);
+
+  if (dz === 1) zValues.push(maxZ, maxZ - 1);
+  else if (dz === -1) zValues.push(minZ, minZ + 1);
+
+  let marked = 0;
+
+  if (xValues.length > 0) {
+    for (const x of xValues) {
+      for (let y = minY; y <= maxY; y++) {
+        for (let z = minZ; z <= maxZ; z++) {
+          if (this._addDirtyAOIfRenderable(Chunk.encodeCoord(x, y, z))) marked++;
+        }
+      }
+    }
+  }
+
+  if (zValues.length > 0) {
+    for (const z of zValues) {
+      for (let y = minY; y <= maxY; y++) {
+        for (let x = minX; x <= maxX; x++) {
+          if (this._addDirtyAOIfRenderable(Chunk.encodeCoord(x, y, z))) marked++;
+        }
+      }
+    }
+  }
+
+  recordChunkPerf('chunk.ao-refresh.mark-boundary', performance.now() - startedAt, {
+    chunkKey: `${this.cx},${this.cz}`,
+    neighborKey: `${neighborCx},${neighborCz}`,
+    marked
+  });
+}
+```
+
+- [ ] **Step 3: 处理 Y 范围风险**
+
+如果本项目中可见实例可能存在 `worldY + 15` 之外的实体结构方块，则不要只扫 `worldY..worldY+15`。改为从 `visibleKeys` 过滤边界：
+
+```js
+for (const code of this.visibleKeys) {
+  const { x, z } = Chunk.decodeCoord(code);
+  const nearX = dx === 1 ? x >= maxX - 1 : dx === -1 ? x <= minX + 1 : false;
+  const nearZ = dz === 1 ? z >= maxZ - 1 : dz === -1 ? z <= minZ + 1 : false;
+  if ((nearX || nearZ) && this._addDirtyAOIfRenderable(code)) marked++;
+}
+```
+
+优先选择能覆盖现有结构高度的实现。
+
+- [ ] **Step 4: 运行 lint**
+
+Run:
+
+```bash
+npm run lint
+```
+
+Expected: 无新增 lint 错误。
+
+---
+
+### Task 5: AOWorker 避免 per request 合并 chunk cache
+
+**Files:**
+- Modify: `src/workers/AOWorker.js`
+
+- [ ] **Step 1: 定义 AOWorker 局部 CHUNK_SIZE**
+
+`GameConfig.js` 当前没有导出 `CHUNK_SIZE`，项目内多个 Worker 也使用局部常量。为避免让 AOWorker 依赖 `ChunkConsolidation.js`，在 AOWorker 顶部定义局部常量：
+
+```js
+const CHUNK_SIZE = 16;
+```
+
+- [ ] **Step 2: 新增世界坐标到 chunkKey 的 helper**
+
+```js
+function getChunkKeyForWorldCoord(x, z) {
+  const cx = Math.floor(Math.floor(x) / CHUNK_SIZE);
+  const cz = Math.floor(Math.floor(z) / CHUNK_SIZE);
+  return `${cx},${cz}`;
+}
+```
+
+- [ ] **Step 3: 新增跨 chunk cache 读取 helper**
+
+```js
+function getEntryFromAnyCachedChunk(x, y, z) {
+  const ix = Math.floor(x);
+  const iy = Math.floor(y);
+  const iz = Math.floor(z);
+  const data = chunkCache[getChunkKeyForWorldCoord(ix, iz)];
+  if (!data) return null;
+
+  const code = encodeCoord(ix, iy, iz);
+  if (data[code] !== undefined) return data[code];
+
+  const strKey = `${ix},${iy},${iz}`;
+  return data[strKey] !== undefined ? data[strKey] : null;
+}
+```
+
+- [ ] **Step 4: 替换 `createOcclusionCheckerFromCache()` 的 merged 构造**
+
+将函数改为：
+
+```js
+function createOcclusionCheckerFromCache() {
+  return function isOccluding(x, y, z) {
+    const entry = getEntryFromAnyCachedChunk(x, y, z);
+    if (!entry) return false;
+    const type = typeof entry === 'string' ? entry : entry.type;
+    if (!type) return false;
+    return isFullCubeOccluder(type);
+  };
+}
+```
+
+注意：当前代码里 `isFullCubeOccluder(props)` 传入的是 props，需核对 `BlockData.js` 函数签名。如果签名要求 type，就传 type；如果要求 props，就保留 `getBlockProperties(type)` 后传 props。
+
+- [ ] **Step 5: 简化 `handleComputeAO()` 调用**
+
+将：
+
+```js
+const isOccluding = createOcclusionCheckerFromCache(chunkKey, neighborChunks || []);
+```
+
+改为：
+
+```js
+const isOccluding = createOcclusionCheckerFromCache();
+```
+
+保留 `neighborChunks` 参数兼容消息协议，但不再依赖它复制数据。
+
+- [ ] **Step 6: 运行 lint**
+
+Run:
+
+```bash
+npm run lint
+```
+
+Expected: 无新增 lint 错误。
+
+---
+
+### Task 6: 浏览器测试与手动性能验证
+
+**Files:**
+- No code changes unless tests reveal regressions
+
+- [ ] **Step 1: 启动开发服务器**
+
+Run:
+
+```bash
+npm run start
+```
+
+Expected: 静态服务器在 8080 或可用端口启动。
+
+- [ ] **Step 2: 运行浏览器测试页**
+
+打开：
+
+```text
+http://localhost:8080/src/tests/index.html
+```
+
+点击“运行所有测试”。
+
+Expected: 所有现有测试通过。
+
+- [ ] **Step 3: 验证 AO 视觉正确性**
+
+手动检查：
+
+- 新加载 chunk 初始可见，随后 AO 正常补齐；
+- chunk 边界没有明显黑线、闪烁或 AO 断层；
+- 挖掘和放置后 consolidation 收敛时 AO 能刷新；
+- Mag7 / TNT 批量删除后 AO 不丢失。
+
+- [ ] **Step 4: 对比 chunk perf 日志**
+
+启用现有 `ChunkPerfMonitor` 日志后观察：
+
+- `chunk.ao-refresh.source-stable.markMs` 明显下降；
+- `chunk.ao-refresh.request.positions` 接近可见实例数；
+- `chunk.ao-refresh.mark-boundary` 不再出现固定 4096 扫描级成本；
+- `non-deferred-finalize` / deferred finalize 不再出现 AO 造成的 30ms 级峰值。
+
+---
+
+## 实施检查点
+
+- [ ] 每个 task 后运行 `npm run lint`。
+- [ ] 修改 Worker 查询后重点检查 chunk 边界 AO。
+- [ ] 任何提交必须等待用户明确指令。
+- [ ] 如果可见实例过滤导致 AO 漏刷，立即回退该过滤条件，保留“只去重重复刷新”和“边界生成”两项低风险优化。

+# AO Refresh Hot Path Design
+
+> **Problem:** chunk finalize 阶段的 AO 稳定刷新仍在主线程做全量标脏、边界扫描和整块同步，导致 `non-deferred-finalize` / deferred finalize task 经常超过帧预算。目标是在不牺牲 AO 正确性的前提下，把 AO 刷新限制到 face culling 后的可见实例和必要边界带，并继续让真实 AO 计算留在 AOWorker。
+
+## 1. 现状判断
+
+当前 AO 真正计算已经在 `src/workers/AOWorker.js` 中执行：
+
+```js
+const { aoLow, aoHigh } = calculateAOForBlock(ix, iy, iz, isOccluding);
+```
+
+但主线程在发送计算请求前仍有明显热路径成本：
+
+```text
+World.onChunkFinalized()
+  -> World.onChunkAOSourceStable(fullRefresh: true, markNeighborBoundaries: true)
+    -> Chunk._refreshAOFromStableSource()
+      -> _markAllBlocksDirtyAO()       // 遍历 blockData，包含隐藏块
+      -> aoBridge.fullSync()           // blockData Map 转 plain object 并 postMessage
+      -> _executeAORefresh()
+        -> decode dirtyAOPositions     // 将全量脏集解码为 positions
+        -> AOWorker.computeAO()
+```
+
+邻居 chunk ready 时还会触发：
+
+```text
+World.onChunkAOSourceStable(markNeighborBoundaries: true)
+  -> neighbor._markBoundaryDirtyAO()
+    -> 遍历 blockDataArray[4096]，按边界筛选
+```
+
+这说明 issue 中“AO 计算虽然在 Worker，但主线程前置工作过重”的判断成立。
+
+## 2. 设计原则
+
+1. AO 真实计算继续在 `AOWorker` 中，主线程只负责决定哪些实例需要刷新和应用结果。
+2. AO 刷新必须在 face culling 之后，以 `visibleKeys` / `instanceIndexMap` 作为候选来源；没有渲染实例的隐藏块不计算 AO。
+3. 首次显示可继续使用中性 AO，待 chunk 稳定后异步补齐真实 AO。
+4. 邻居到达只刷新边界影响带，不触发本 chunk 或邻居的全量 AO。
+5. 保持现有 delta/fullSync 时序语义，先做低风险热路径优化，再改 Worker 内部查询结构。
+
+## 3. 拟采用方案
+
+### 3.1 去除重复 finalize AO 刷新
+
+`Chunk.runDeferredFinalizePhase()` 当前在 `_needsDeferredAOStabilization` 分支中触发一次全量 AO，随后如果 `hasDeferredFinalizeWork` 变为 false，又会在 `deferred-finalize-done` 分支触发第二次全量 AO。
+
+设计：在同一轮 `runDeferredFinalizePhase()` 中记录 `aoRefreshTriggeredThisPass`。如果已经因为 `_needsDeferredAOStabilization` 触发过 AO，则本轮完成时不再触发 `deferred-finalize-done` 的 AO 刷新。
+
+### 3.2 全量刷新改为“可见实例刷新”
+
+新增或替换 `_markAllBlocksDirtyAO()` 的行为：
+
+- 优先遍历 `this.instanceIndexMap` 中的实例坐标；
+- 其次可回退到 `this.visibleKeys`；
+- 最后才回退到 `this.blockData`，仅用于兼容没有可见索引的旧路径。
+
+候选坐标仍需校验：
+
+- `blockData` 中存在该方块；
+- 方块类型是 solid 且非 transparent；
+- 当前 chunk 的 mesh/全局实例中存在对应实例。
+
+这样 full refresh 不再对被 face culling 剔除的隐藏块计算 AO。
+
+### 3.3 边界 AO 标记改为坐标生成
+
+`_markBoundaryDirtyAO(neighborCx, neighborCz)` 不再扫描整个 `blockDataArray`。根据邻居方向直接生成边界影响带：
+
+- 邻居在 `+X`：本 chunk 需要刷新靠近 `maxX` 的两列；
+- 邻居在 `-X`：刷新靠近 `minX` 的两列；
+- 邻居在 `+Z`：刷新靠近 `maxZ` 的两列；
+- 邻居在 `-Z`：刷新靠近 `minZ` 的两列；
+- y 范围使用 chunk 可用高度范围，优先来自 `blockDataArray` 覆盖范围和 `worldY`，必要时回退到遍历 `visibleKeys` 的边界过滤。
+
+每个候选坐标通过统一 helper 校验是否为 AO 可刷新实例，再加入 `dirtyAOPositions`。
+
+### 3.4 AOWorker 遮挡查询避免每次合并大对象
+
+`AOWorker.createOcclusionCheckerFromCache()` 当前每个请求都会把当前 chunk 和邻居 cache 复制到 `merged` 对象。这个成本在 Worker，不阻塞主线程，但会拖慢 AO 回包。
+
+设计：新增基于坐标定位 chunk cache 的查询函数：
+
+```js
+function getChunkKeyForWorldCoord(x, z) {
+  const cx = Math.floor(x / CHUNK_SIZE);
+  const cz = Math.floor(z / CHUNK_SIZE);
+  return `${cx},${cz}`;
+}
+```
+
+`isOccluding(x, y, z)` 直接计算 `chunkKey`，查 `chunkCache[chunkKey][encodeCoord(x, y, z)]`。这会删除 per request 的 `merged` 构造。
+
+## 4. 非目标
+
+- 不改变 AO shader、AO packing 格式或 `aAoLow` / `aAoHigh` attribute。
+- 不把 bootstrap 阶段 AO 改回 WorldWorker 同步计算。
+- 不改 IndexedDB、WorldStore 或 chunk 存档格式。
+- 不在本次重构 `Chunk.js` 大文件边界，只做局部 helper 提取。
+
+## 5. 正确性约束
+
+| 场景 | 预期行为 |
+|------|----------|
+| 新 chunk 首次显示 | 先显示中性 AO，稳定后异步补真实 AO |
+| 邻居 chunk 后到达 | 只刷新双方接壤边界影响带 |
+| 放置方块 | 当前动态交互期仍延迟到 consolidation 后收敛 |
+| 删除方块 / 批量删除 | 保持现有 `_markDirtyAO()` 3x3x3 影响区语义 |
+| chunk 正在 consolidation | AO 回包仍由 `_aoSourceVersion` 丢弃过期结果 |
+| 可见集合缺失 | 回退到旧全量 blockData 标记，优先保证正确性 |
+
+## 6. 观测与验证
+
+新增或扩展 `recordChunkPerf` 观测：
+
+- `chunk.ao-refresh.mark-visible`
+- `chunk.ao-refresh.mark-boundary`
+- `chunk.ao-refresh.full-sync`
+- `chunk.ao-refresh.collect-positions`
+- `chunk.ao-refresh.apply-results`
+- `worker.ao.compute`
+
+验证目标：
+
+- `non-deferred-finalize` / `deferred-finalize` 不再出现由 AO 前置工作引起的 30ms 级峰值。
+- full refresh positions 数量接近可见实例数量，而不是 `blockData` 全量数量。
+- 邻居边界刷新不再每方向扫描 4096 slot。
+- AO 视觉在 chunk 边界、挖掘、放置、批量删除后保持稳定。
+
+## 7. 推荐实施顺序
+
+1. 添加 AO 热路径计时，确认改动前后数据。
+2. 修复 deferred finalize 重复 AO 刷新。
+3. 将 full refresh 候选从全量 `blockData` 改为 `instanceIndexMap` / `visibleKeys`。
+4. 将边界 dirty 标记从全数组扫描改为边界带生成。
+5. 优化 AOWorker 遮挡查询，删除 per request `merged` 构造。
+6. 运行 lint 和浏览器测试页，最后用 chunk perf 日志做手动对比。

 Health 是一个全面的项目体检工具，专注于识别**历史技术债务**与评估**当前代码质量**。
 
+**支持项目类型：**
+- Node.js / JavaScript / TypeScript
+- Flutter / Dart
+- Python / Go / Java / Ruby / PHP / Rust
+- **iOS / Objective-C / Swift** (新增)
+
 **核心设计原则：**
 - 区分"历史遗留债务"与"新增问题"（债务清理应加分）
 - 重视可维护性指标（文档、测试、注释）
 - 降低对遗留代码结构问题的惩罚权重
 - 最终评分反映项目真实健康状况，而非单纯问题计数
 
+**iOS 项目特别关注点：**
+- 头文件注释完整度（公共 API 文档）
+- 代码组织（Utils/Categories/Constants 目录结构）
+- 内存管理规范（ARC 合规性）
+- 命名规范（Objective-C 编码约定）
+- 静态分析工具配置（SwiftLint/OCLint）
+

+## 修复建议
+
+### 立即行动项 (本周内)
+
+```bash
+# 1. 将所有硬编码密钥移至环境变量
+export DATABASE_PASSWORD="your-password"
+export REDIS_PASSWORD="your-password"
+export OSS_ACCESS_KEY_SECRET="your-secret"
+export FAI_API_KEY="your-key"
+
+# 2. 审查并修复认证绕过配置
+# 编辑 server/src/config/config.default.ts
+# 移除敏感接口的 bypassLogin 配置
+
+# 3. 运行安全审计
+npm audit fix
+yarn audit fix
+```
+
+### 短期修复 (本月内)
+
+1. **代码重构**: 将超大文件 (>2000 行) 拆分为多个模块
+2. **命名规范**: 统一类名使用 PascalCase，修正拼写错误
+3. **依赖整理**: 修正依赖分类，移除内置模块依赖
+4. **添加测试**: 配置 Jest/Vitest，编写核心功能单元测试
+
+### 中期优化 (下季度)
+
+1. **引入统一输入验证**: 使用 `class-validator` + `class-transformer`
+2. **配置安全中间件**: 添加 `helmet`, `express-rate-limit`
+3. **完善文档**: 编写 README、API 文档、部署文档
+4. **建立 CI/CD**: 配置自动化测试和部署流程

+### 立即行动项 (本周内)
+
+1. **修复安全漏洞**：移除所有硬编码的密钥和密码
+2. **清理大文件**：将超过800行的文件按功能拆分
+3. **处理P0级问题**：优先修复标记为P0的问题
+
+### 短期修复 (本月内)
+
+1. **代码重构**：优化命名规范，统一代码风格
+2. **添加测试**：为核心功能编写单元测试
+3. **完善文档**：补充README和API文档
+
+### 中期优化 (下季度)
+
+1. **引入静态分析**：配置SwiftLint/ESLint等工具
+2. **建立CI/CD**：配置自动化测试和代码检查
+3. **定期健康检查**：每月运行一次健康检查

+### Task 5: AO 稳定源传播补齐对角邻居语义
+
+**Files:**
+- Modify: `src/world/World.js`
+- Modify: `src/tests/test-world.js`
+
+- [ ] **Step 1: 先写对角邻居传播测试**
+
+在 `src/tests/test-world.js` 新增测试，覆盖下面场景：
+
+- 中心 chunk 稳定后，正交四邻仍会收到 `_markBoundaryDirtyAO()`；
+- 至少一个对角邻居（如 `+1,+1`）若已就绪，也应收到 AO 边界标记或等价刷新触发；
+- 对角邻居在 `dirtyAOPositions.size > 0` 时，应被 `_refreshAOFromStableSource()` 刷新。
+
+不要只验证调用次数，要断言被调用的邻居坐标集合，避免后续有人改回 4 邻传播而测试仍误过。
+
+- [ ] **Step 2: 扩展 `onChunkAOSourceStable()` 的传播范围**
+
+将当前只遍历四邻：
+
+```js
+const dirs = [[1,0],[-1,0],[0,1],[0,-1]];
+```
+
+扩展为覆盖 AO 语义所需的八邻域，并明确区分：
+
+- 正交邻居：继续走边界带刷新；
+- 对角邻居：至少要触发角点影响带刷新，不能因为没有共享整条边就完全跳过。
+
+如不希望复用 `_markBoundaryDirtyAO()` 处理对角语义，可在 `Chunk.js` 追加专门的角点 helper，但要保持计划内职责清晰。
+
+- [ ] **Step 3: 为对角传播选择明确实现**
+
+推荐二选一，实施时固定一种，不要混搭：
+
+```text
+A. 在 Chunk 侧新增 _markCornerDirtyAO(neighborCx, neighborCz)，只标记对应角点 2x2 带
+B. 扩展 _markBoundaryDirtyAO()，让其同时接受对角方向并生成角点影响带
+```
+
+优先推荐 A，语义更清楚，也更不容易把边界带和角点带混在一起。
+
+- [ ] **Step 4: 保持“只刷新已就绪且非合并中的邻居”语义**
+
+修改传播范围后，继续满足现有守卫条件：
+
+- `nChunk` 存在；
+- `nChunk.isReady === true`；
+- `nChunk.isConsolidating !== true` 时才立即刷新。
+
+如果仅标脏不立即刷新，也要保留这一时序约束并补对应测试。

+### 3.4 对角邻居传播补齐 AO 语义
+
+AO 计算依赖 `3x3x3` 邻域，而不仅仅是共享边的四邻 chunk。因此 `World.onChunkAOSourceStable()` 不能只向正交四邻传播稳定源事件。
+
+设计要求：
+
+- 正交邻居继续刷新边界影响带；
+- 对角邻居也必须收到 AO 脏位传播，否则角点处会在“对角 chunk 晚到”时留下旧 AO；
+- 对角传播不应退化为全量刷新，只允许刷新对应角点的小范围影响带。
+
+实现上可二选一：
+
+- 在 `Chunk` 侧新增专门的角点 helper（推荐）；
+- 扩展 `_markBoundaryDirtyAO()` 使其同时处理对角方向。
+
+无论采用哪种方式，都应保持“只对已就绪、非 consolidation 中的邻居执行即时刷新”的现有时序约束。
+
+### 3.5 AOWorker 遮挡查询避免每次合并大对象
 
 `AOWorker.createOcclusionCheckerFromCache()` 当前每个请求都会把当前 chunk 和邻居 cache 复制到 `merged` 对象。这个成本在 Worker，不阻塞主线程，但会拖慢 AO 回包。

consolidation 重建整个 chunk 的 InstancedMesh 时，WorldWorker 写入的
中性 AO 值错误（aoLow=1, aoHigh=1 导致几乎所有顶点 AO=0，即全黑），
且重建后非脏方块的原有正确 AO 值被丢弃，仅 dirtyAOPositions（3x3x3
范围）被 AOWorker 修正，其余方块保持深色。

修复方案：
1. ChunkConsolidation 新增旧 AO 提取/恢复机制 — 清理旧 mesh 前提取
   所有可见方块的 AO，新 mesh 构建后对非脏位置恢复旧 AO 值。同时支持
   本地路径（group.children）和全局路径（GlobalInstancedMeshManager）。
2. WorldWorker 中性 AO 值修正为 0x00ffffff（全亮），作为安全网处理
   面剔除变化后新出现方块的 AO 初值。

之前跳过 dirty 位置不恢复 AO，依赖异步 AO 刷新填补，导致合并完成后
有短暂窗口 AO 掉回中性值。现在 dirty 位置仍优先写回旧 AO，只有
新出现且无旧值的 dirty 实例才同步补算当前 AO。

+# BlockData Authority Unification Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** 将运行时逻辑真相统一收敛到 `blockData` 语义，保留当前所有功能，同时去掉 `WorldRuntime` / `PersistenceService` 周围的 blockData 快照链，让 `MemoryWorldStore` 只承担未加载 chunk 的 `blockData` 容器职责，`IndexedDB` 降级为冷存储层。
+
+**Architecture:** 已加载 chunk 的唯一逻辑权威由 `Chunk.blockData` 持有；未加载 chunk 的逻辑权威由 `MemoryWorldStore.chunks[].blockData` 持有。`visibleKeys`、`solidBlocks`、`blockDataArray`、`meshData`、AO mirror 等全部保留，但统一视为派生索引或渲染载荷。持久化层退出 runtime 正确性主链路，只负责导入、导出和异步冷落盘。
+
+**Tech Stack:** JavaScript, Three.js, Web Workers, IndexedDB, ESLint, 浏览器内测试页面 `src/tests/index.html`
+

+### 重点测试文件
+
+- Test: `src/tests/test-chunk.js`
+- Test: `src/tests/test-world.js`
+- Test: `src/tests/test-world-runtime.js`
+- Test: `src/tests/test-runtime-session-persistence.js`
+
+---
+
+### Task 1: 先把运行时权威语义收敛到 `Chunk.blockData` 与 `MemoryWorldStore`
+
+**Files:**
+- Modify: `src/world/Chunk.js`
+- Modify: `src/world/MemoryWorldStore.js`
+- Modify: `src/world/World.js`
+- Test: `src/tests/test-chunk.js`
+- Test: `src/tests/test-world.js`
+
+- [ ] **Step 1: 写失败测试，固定“loaded / unloaded 两种 blockData 持有语义”**
+
+在 `src/tests/test-world.js` 和 `src/tests/test-chunk.js` 增加测试，覆盖：
+
+- 已加载 chunk 时逻辑真相以 `Chunk.blockData` 为准
+- chunk unload 前同步后，`MemoryWorldStore` 中对应 chunkRecord 持有同样的 `blockData`
+- reload 后，重新加载的 chunk 恢复出相同的 `blockData`
+
+测试重点：
+
+- 不能只测“有数据”
+- 要测 `blockData` 内容完全一致
+
+- [ ] **Step 2: 运行测试，确认当前语义未被显式保证**
+
+Run:
+- 启动 `npm run start`
+- 打开 `http://localhost:8080/src/tests/index.html`
+- 运行相关测试
+
+Expected:
+- 新增语义测试至少有一部分失败，暴露现有职责边界不清晰
+
+- [ ] **Step 3: 修改 `Chunk.blockData` 注释和加载路径语义**
+
+在 `src/world/Chunk.js`：
+
+- 更新 `blockData` 注释为“完整逻辑块集合”
+- 明确 `loadFromRecord()` / `_injectBlockData()` 在 loaded chunk 接管逻辑权威
+
+不要改：
+
+- `visibleKeys`
+- `solidBlocks`
+- `blockDataArray`
+- AO / tombstone 功能
+
+- [ ] **Step 4: 修改 `MemoryWorldStore` 注释和最小辅助接口**
+
+在 `src/world/MemoryWorldStore.js`：
+
+- 把类注释改成“未加载 chunk 的 blockData 容器 + 世界级索引”
+- 新增一个最小辅助接口，例如：
+  - `syncChunkRecord(cx, cz, record)`
+  - 或 `syncLoadedChunkToStore(cx, cz, chunkLikeRecord)`
+
+要求：
+
+- 不要引入新的运行时快照层
+- 只做数据接班同步
+
+- [ ] **Step 5: 在 `World` 中补上 unload 前同步入口**
+
+在 `src/world/World.js` 增加一个集中入口，例如：
+
+- `beforeChunkUnloadSync(chunk)`
+
+职责：
+
+- 用当前 chunk 的 `blockData`
+- 加上 `runtimeEntities/staticEntities/runtimeSeedData`
+- 覆盖 `MemoryWorldStore` 中对应记录
+
+- [ ] **Step 6: 运行相关测试确认通过**
+
+Run:
+- 测试页面中运行 `test-world.js`
+- 运行 `test-chunk.js`
+
+Expected:
+- 新增 loaded/unloaded 权威语义测试通过
+
+- [ ] **Step 7: 运行 lint**
+
+Run: `npm run lint`
+Expected: PASS
+
+---
+
+### Task 2: 去掉 `WorldRuntime` 的 blockData 快照主链路
+
+**Files:**
+- Modify: `src/world/WorldRuntime.js`
+- Modify: `src/world/ChunkPersistence.js`
+- Modify: `src/world/Chunk.js`
+- Create: `src/world/ColdPersistenceCoordinator.js`
+- Test: `src/tests/test-world-runtime.js`
+- Test: `src/tests/test-runtime-session-persistence.js`
+
+- [ ] **Step 1: 写失败测试，固定“runtime 正确性不依赖 blockDataSnapshot”**
+
+在 `src/tests/test-world-runtime.js` 和 `src/tests/test-runtime-session-persistence.js` 增加测试：
+
+- 单块修改后，即便不构造 `dirtyEntry.blockDataSnapshot`，chunk unload/reload 仍不丢数据
+- `saveDebounced()` 不需要 `flushChunk()` 成功才能保证运行时正确性
+
+- [ ] **Step 2: 运行测试，确认当前实现仍依赖 snapshot 语义**
+
+Run:
+- 浏览器测试页运行新增测试
+
+Expected:
+- 至少有测试因 `_dirtyChunks[].blockDataSnapshot` 或 `flushChunk()` 假设而失败
+
+- [ ] **Step 3: 新增冷存储协调器最小骨架**
+
+在 `src/world/ColdPersistenceCoordinator.js` 实现最小版本：
+
+- `schedulePersistChunk(cx, cz)`
+- `flushDirtyChunks()`
+
+第一版只要求：
+
+- 记录哪些 chunk 需要冷落盘
+- 提供未来接入 `WorldStore` 的位置
+
+不要第一步就做复杂批处理。
+
+- [ ] **Step 4: 修改 `ChunkPersistence.saveDebounced()`**
+
+在 `src/world/ChunkPersistence.js`：
+
+- 不再直接调用 `runtime.flushChunk()`
+- 改为调用新的冷存储协调器 `schedulePersistChunk()`
+
+目标：
+
+- runtime 正确性退出 `flushChunk()` 依赖
+
+- [ ] **Step 5: 收缩 `WorldRuntime.recordBlockMutation()`**
+
+在 `src/world/WorldRuntime.js`：
+
+- 停止首次脏化时创建完整 `blockDataSnapshot`
+- 将其职责收缩为“记录 chunk 脏状态”或直接由新协调器接管
+
+要求：
+
+- 保持 `markChunkDirty()` 语义兼容
+- 不要破坏现有其他测试
+
+- [ ] **Step 6: 将 `flushChunk()` 明确降级为冷存储工具接口**
+
+在 `src/world/WorldRuntime.js`：
+
+- 标注 `flushChunk()` 不再参与 runtime 正确性
+- 停止让 `saveDebounced()` 依赖它
+
+第一阶段允许保留：
+
+- `flushAllDirty()`
+- `_commitChunkRecord()`
+
+仅作为冷写工具。
+
+- [ ] **Step 7: 运行运行时相关测试**
+
+Run:
+- 测试页面中运行 `test-world-runtime.js`
+- 运行 `test-runtime-session-persistence.js`
+
+Expected:
+- 卸载/重载正确性不再依赖 `blockDataSnapshot`
+
+- [ ] **Step 8: 运行 lint**
+
+Run: `npm run lint`
+Expected: PASS
+
+---
+
+### Task 3: 保持渲染索引与查询索引原样工作
+
+**Files:**
+- Modify: `src/world/Chunk.js`
+- Test: `src/tests/test-chunk.js`
+- Test: `src/tests/test-world.js`
+
+- [ ] **Step 1: 写失败测试，固定“索引层保留原用途”**
+
+在 `src/tests/test-chunk.js` 增加测试，覆盖：
+
+- `visibleKeys` 仍服务可见性判断，不因权威语义收敛被合并或清空
+- `solidBlocks` 仍服务碰撞判断
+- `blockDataArray + solidBlockIds` 仍保持 chunk 内快路径可用
+
+- [ ] **Step 2: 运行测试，确认索引层行为当前有覆盖缺口**
+
+Run:
+- 测试页面运行相关测试
+
+Expected:
+- 至少需要补一个或多个更明确的断言
+
+- [ ] **Step 3: 修正 `Chunk` 中可能依赖旧持久化假设的逻辑**
+
+在 `src/world/Chunk.js`：
+
+- 检查 `_updateBlockState()`
+- 检查 `acceptScatteredBlocks()`
+- 检查 `appendScatteredBlocks()`
+
+要求：
+
+- 只允许 `blockData` 驱动索引层更新
+- 禁止让索引层去反向决定逻辑真相
+
+- [ ] **Step 4: 明确保留 tombstone / AO mirror / renderDelta**
+
+在 `src/world/Chunk.js` 添加或修正文档注释：
+
+- `deletedBlockTombstones` 继续保留
+- `AOBridge` 镜像仍从 `blockData` 派生
+- `renderDelta` 仍供全局实例系统消费
+
+- [ ] **Step 5: 运行 chunk/world 相关测试**
+
+Run:
+- 测试页面运行 `test-chunk.js`
+- 运行 `test-world.js`
+
+Expected:
+- 索引层与渲染补丁相关测试通过
+
+- [ ] **Step 6: 运行 lint**
+
+Run: `npm run lint`
+Expected: PASS
+
+---
+
+### Task 4: 手动保存改为直接从 `MemoryWorldStore` 导出
+
+**Files:**
+- Modify: `src/core/Game.js`
+- Modify: `src/world/World.js`
+- Test: `src/tests/test-world-runtime.js`
+
+- [ ] **Step 1: 写失败测试，固定 `collectSnapshot()` 的新来源**
+
+在相关测试中新增断言：
+
+- `collectSnapshot()` 不再调用 `worldStore.getChunkRecord()`
+- 保存前先同步所有 loaded chunks 到 `MemoryWorldStore`
+- 导出结果来自 `MemoryWorldStore`
+
+- [ ] **Step 2: 运行测试确认当前实现仍依赖 `worldStore.getChunkRecord()`**
+
+Run:
+- 浏览器测试页运行新增测试
+
+Expected:
+- 新增测试失败，暴露当前逐 chunk 冷读取路径
+
+- [ ] **Step 3: 在 `World` 中新增保存前同步入口**
+
+在 `src/world/World.js` 增加：
+
+- `syncAllLoadedChunksToMemoryStore()`
+
+职责：
+
+- 遍历 `this.chunks`
+- 将每个 loaded chunk 当前 `blockData` 和实体记录同步回 `MemoryWorldStore`
+
+- [ ] **Step 4: 改写 `Game.collectSnapshot()`**
+
+在 `src/core/Game.js`：
+
+- 调用 `world.syncAllLoadedChunksToMemoryStore()`
+- 直接从 `world.memoryWorldStore` 读取 chunk 记录
+- 生成 `worldDeltas`
+
+要求：
+
+- 不再逐 chunk `await world.worldStore.getChunkRecord()`
+
+- [ ] **Step 5: 运行相关测试**
+
+Run:
+- 浏览器测试页中运行 `test-world-runtime.js`
+
+Expected:
+- `collectSnapshot()` 路径测试通过
+
+- [ ] **Step 6: 运行 lint**
+
+Run: `npm run lint`
+Expected: PASS
+
+---
+
+### Task 5: 手动导入改为先写 `MemoryWorldStore`，再同步已加载 chunk
+
+**Files:**
+- Modify: `src/core/Game.js`
+- Modify: `src/world/World.js`
+- Modify: `src/services/PersistenceService.js`
+- Test: `src/tests/test-world-runtime.js`
+
+- [ ] **Step 1: 写失败测试，固定 `applySaveData()` 新链路**
+
+新增测试覆盖：
+
+- `applySaveData()` 不再依赖 `persistenceService.injectSaveData()`
+- 存档中的 `worldDeltas` 先写入 `MemoryWorldStore`
+- 如果目标 chunk 已加载，需同步刷新对应 `Chunk.blockData`
+
+- [ ] **Step 2: 运行测试确认当前仍依赖 `injectSaveData()`**
+
+Run:
+- 浏览器测试页运行新增测试
+
+Expected:
+- 当前实现因调用 `injectSaveData()` 而失败
+
+- [ ] **Step 3: 修改 `Game.applySaveData()`**
+
+在 `src/core/Game.js`：
+
+- 将 `saveData.worldDeltas` 转写到 `world.memoryWorldStore`
+- 对已加载 chunk：
+  - 覆盖其 `blockData`
+  - 重建 `blockDataArray`
+  - 重建 `solidBlocks`
+  - 触发可见性 / mesh 重新装配
+
+- [ ] **Step 4: 将 `PersistenceService.injectSaveData()` 降级为 deprecated**
+
+在 `src/services/PersistenceService.js`：
+
+- 保留旧接口以兼容旧代码
+- 注释标明不再是 runtime 主链路
+
+- [ ] **Step 5: 运行导入相关测试**
+
+Run:
+- 浏览器测试页运行 `test-world-runtime.js`
+
+Expected:
+- 存档导入、loaded chunk 覆盖、reload 恢复测试通过
+
+- [ ] **Step 6: 运行 lint**
+
+Run: `npm run lint`
+Expected: PASS
+
+---
+
+### Task 6: 收缩旧持久化缓存层，只保留冷存储职责
+
+**Files:**
+- Modify: `src/world/WorldRuntime.js`
+- Modify: `src/services/PersistenceService.js`
+- Modify: `src/world/WorldStore.js`
+- Modify: `src/workers/PersistenceWorker.js`
+- Test: `src/tests/test-world-runtime.js`
+
+- [ ] **Step 1: 写失败测试，固定“运行时不再依赖旧 cache 层”**
+
+测试覆盖：
+
+- `PersistenceService.cache` 不再承载 runtime blockData 权威
+- `WorldRuntime._regionCache` 只服务冷读取/预取
+- `pendingUnloadFlushQueue` 不再参与运行时正确性
+
+- [ ] **Step 2: 运行测试，确认当前实现仍保留旧缓存职责**
+
+Run:
+- 浏览器测试页运行新增测试
+
+Expected:
+- 测试失败，暴露旧缓存职责仍在
+
+- [ ] **Step 3: 收缩 `PersistenceService` 的运行时接口**
+
+在 `src/services/PersistenceService.js`：
+
+- 标记以下方法 deprecated：
+  - `snapshotChunkBlocks`
+  - `hydrateChunkBlocks`
+  - `replaceChunkBlocks`
+  - `injectSaveData`
+
+- [ ] **Step 4: 收缩 `WorldRuntime` 的旧 flush 队列职责**
+
+在 `src/world/WorldRuntime.js`：
+
+- 将 `pendingUnloadFlushQueue` 标注为冷写兼容工具
+- 检查是否仍有调用路径依赖它保证 runtime 正确性
+- 若有，改接到 `MemoryWorldStore`
+
+- [ ] **Step 5: 暂不删除 `PersistenceWorker.regionCache`，只改注释和边界**
+
+在 `src/workers/PersistenceWorker.js`：
+
+- 注释说明其仅服务冷启动/冷读取
+- 不把它作为运行时主链路优化项
+
+原因：
+
+- 避免过早删除导致旧档冷启动性能回退
+
+- [ ] **Step 6: 运行运行时测试**
+
+Run:
+- 浏览器测试页运行 `test-world-runtime.js`
+
+Expected:
+- 无回归
+
+- [ ] **Step 7: 运行 lint**
+
+Run: `npm run lint`
+Expected: PASS
+
+---
+
+### Task 7: 完整回归与性能验证
+
+**Files:**
+- Test: `src/tests/test-chunk.js`
+- Test: `src/tests/test-world.js`
+- Test: `src/tests/test-world-runtime.js`
+- Test: `src/tests/test-runtime-session-persistence.js`
+
+- [ ] **Step 1: 运行浏览器内测试全套回归**
+
+Run:
+- `npm run start`
+- 打开 `http://localhost:8080/src/tests/index.html`
+- 点击“运行所有测试”
+
+Expected:
+- 所有现有测试通过
+
+- [ ] **Step 2: 手动验证单块修改与 reload**
+
+手动步骤：
+
+1. 放置方块
+2. 删除方块
+3. 离开区块触发卸载
+4. 返回原区块触发 reload
+
+Expected:
+- 方块状态正确恢复
+
+- [ ] **Step 3: 手动验证导入导出**
+
+手动步骤：
+
+1. 导出当前存档
+2. 刷新页面
+3. 导入刚导出的存档
+
+Expected:
+- 世界块数据、实体数据、玩家状态正确恢复
+
+- [ ] **Step 4: 手动验证渲染与碰撞功能未丢失**
+
+重点检查：
+
+- `visibleKeys` 驱动的上屏/补面仍正常
+- `solidBlocks` 驱动的碰撞仍正常
+- AO 无明显错乱
+
+- [ ] **Step 5: 记录 Chrome Trace 基线与结果**
+
+对比项：
+
+- consolidation 后长帧
+- `WorldRuntime.flushChunk()` 是否已退出热路径
+- 是否仍有大块 `postMessage` / `applyRegionPatch` 热点
+
+Expected:
+- 热路径显著收缩
+- 若仍有长帧，应归因为下一阶段“持久化粒度优化”而不是旧 snapshot 链
+
+- [ ] **Step 6: 运行 lint 作为最终门禁**
+
+Run: `npm run lint`
+Expected: PASS

+# BlockData Authority Unification Design
+
+> **Problem:** 当前 runtime 期间的逻辑方块真相被拆散在 `Chunk.blockData`、`MemoryWorldStore.chunks[].blockData`、`WorldRuntime` 的快照链、`PersistenceService.cache` 与 `PersistenceWorker.regionCache` 周围。结果是运行时既存在双权威语义，也存在多条全量 clone / region patch / flush queue 链路，导致数据层次复杂、拷贝次数多、`postMessage` 载荷过大，且后续优化难以落点。
+
+## 1. Goal
+
+本设计的目标是把运行时的逻辑真相统一收敛到 `blockData` 语义上，并在此基础上保留当前所有关键功能：
+
+1. 已加载 chunk 的逻辑真相由 `Chunk.blockData` 唯一承载
+2. 未加载 chunk 的逻辑真相由 `MemoryWorldStore` 持有对应 chunk 的 `blockData`
+3. `visibleKeys`、`solidBlocks`、`blockDataArray`、`meshData` 等结构继续保留，但明确降级为派生索引或渲染载荷
+4. `IndexedDB` 降级为冷存储 / 导出 / 刷新恢复来源，不再参与 runtime 权威判断
+5. 消灭运行时的 blockData 全量快照链，减少 clone、序列化和跨线程传输次数，为后续 `postMessage` / 持久化粒度优化打基础
+
+## 2. Non-Goals
+
+本次设计明确不做以下事情：
+
+1. 不重写 `visibleKeys`、`solidBlocks`、`blockDataArray` 的用途与算法
+2. 不改变 AO / Face Culling / Global Instanced Mesh 的核心渲染策略
+3. 不把特殊实体逻辑硬塞进普通 `blockData` 语义
+4. 不在第一阶段改成 chunk 级独立 `IndexedDB` store
+5. 不在第一阶段推进 TypedArray 化的权威存储
+6. 不要求本次一并解决所有渲染性能热点
+
+## 3. Current System Reality
+
+### 3.1 当前并非单一运行时权威
+
+当前代码中，逻辑真相至少被拆在两处：
+
+- 已加载 chunk 的真相主要在 `Chunk.blockData`
+- 未加载 chunk 的真相主要在 `MemoryWorldStore.chunks[].blockData`
+
+这本身是合理的冷热分层，但问题在于系统没有把它们表达为“同一语义在 loaded / unloaded 两种形态下的持有者”，而是让它们看起来像两套并行权威。
+
+### 3.2 运行时仍然保留旧持久化快照链
+
+尽管若干注释已将 `IndexedDB` 描述为冷存储，但当前运行时仍保留下列热路径：
+
+- `Chunk.saveDebounced()`
+- `WorldRuntime.recordBlockMutation()`
+- `WorldRuntime._dirtyChunks[].blockDataSnapshot`
+- `WorldRuntime.flushChunk()`
+- `pendingUnloadFlushQueue`
+- `WorldStore.commitChunkRecord()`
+- `PersistenceWorker.applyRegionPatch()`
+
+这意味着：
+
+- runtime 期间仍在构造稳定 blockData 快照
+- 仍在维护 region 级 patch / flush 队列
+- 仍有完整对象跨线程传输和 `IndexedDB.put()` 的结构化复制
+
+### 3.3 当前渲染与查询索引本身并不是问题
+
+以下结构虽然重复了部分 block 信息，但其职责是合理的：
+
+- `visibleKeys`：显示可见性索引
+- `solidBlocks`：碰撞索引
+- `blockDataArray` + `solidBlockIds` + palette：chunk 内高频查询索引
+- `meshData` / `instanceIndexMap` / `renderDelta`：渲染载荷与增量补丁
+- `lightSourceCoords` / `dirtyAOPositions`：光照与 AO 派生索引
+- `deletedBlockTombstones`：异步一致性保护层
+
+因此本设计不是“去掉所有重复数据”，而是“去掉所有重复权威和重复快照链”。
+
+## 4. Proposed Authority Model
+
+### 4.1 统一语义：`blockData` 是唯一逻辑真相
+
+新模型里，`blockData` 作为概念上的唯一逻辑真相，覆盖：
+
+- 地图中已知存在的方块
+- 玩家修改后的方块
+- 跨 chunk 结构归属到当前 chunk 的方块
+- 需要以块形式存在的逻辑占位
+
+但它不覆盖：
+
+- 当前是否可见
+- 当前实例索引
+- 当前 AO attribute
+- 当前是否已上传 GPU
+
+这些都属于派生层。
+
+### 4.2 Loaded / Unloaded 两种持有形态
+
+`blockData` 在运行时有两种持有形态：
+
+1. **Loaded 形态**
+   - 由 `Chunk.blockData` 持有
+   - 当 chunk 已加载时，它是该 chunk 的唯一活跃逻辑权威
+
+2. **Unloaded 形态**
+   - 由 `MemoryWorldStore.chunks[].blockData` 持有
+   - 当 chunk 被卸载后，它接管该 chunk 的逻辑真相
+
+这意味着：
+
+- `MemoryWorldStore` 不能删除
+- 但它不再被视为“另一套并行权威模型”
+- 它应被重新定义为“未加载 chunk 的 `blockData` 容器 + 世界级索引”
+
+### 4.3 冷存储退出运行时权威判断
+
+`IndexedDB` 在目标模型中只负责：
+
+- 启动时读入旧档
+- 手动保存或后台异步落盘
+- 刷新页面后的恢复来源
+
+运行时正确性不再依赖：
+
+- `WorldRuntime.blockDataSnapshot`
+- `PersistenceService.cache`
+- `pendingUnloadFlushQueue`
+- `PersistenceWorker.regionCache`
+
+## 5. Target Layering
+
+### 5.1 权威逻辑层
+
+- `Chunk.blockData`
+- `MemoryWorldStore.chunks[].blockData`
+
+语义：世界逻辑真相，只在 loaded / unloaded 两种状态下切换持有者。
+
+### 5.2 渲染索引层
+
+- `Chunk.visibleKeys`
+
+语义：当前是否应显示、是否参与补面与可见块更新。
+
+### 5.3 碰撞索引层
+
+- `Chunk.solidBlocks`
+
+语义：当前是否是实心块、是否参与碰撞和物理查询。
+
+### 5.4 高频查询索引层
+
+- `Chunk.blockDataArray`
+- `Chunk.solidBlockIds`
+- `Chunk.blockPalette`
+- `Chunk.blockPaletteReverse`
+
+语义：服务 chunk 内高频 `isSolid` / `resolveBlockOwner` / 局部块访问，不承担权威职责。
+
+### 5.5 渲染载荷层
+
+- Worker `meshData`
+- `Chunk.instanceIndexMap`
+- `Chunk.renderDelta`
+- `GlobalInstancedMeshManager` 的 chunk 输出状态
+
+语义：面向渲染提速和 GPU 输出。
+
+### 5.6 光照与一致性保护层
+
+- `Chunk.lightSourceCoords`
+- `Chunk.dirtyAOPositions`
+- AO Worker 的 `blockData` 镜像
+- `Chunk.deletedBlockTombstones`
+
+语义：AO / 光照增量刷新与晚到回包保护。
+
+### 5.7 实体与冷存储层
+
+- `runtimeEntities`
+- `staticEntities`
+- `entityCollisionIndex`
+- `IndexedDB`
+
+语义：实体域权威与冷存储。
+
+## 6. Target Data Flow
+
+### 6.1 单块修改
+
+目标链路：
+
+```text
+WorldAccessLayer.setBlock/removeBlock
+-> Chunk._updateBlockState()
+-> 修改 Chunk.blockData
+-> 增量更新 visibleKeys / solidBlocks / blockDataArray / lightSourceCoords / dirtyAOPositions / renderDelta
+-> AOBridge / tombstones 同步
+-> MemoryWorldStore.applyBlockMutation()
+-> 标记冷存储落盘脏块（仅标脏，不构造快照）
+```
+
+关键约束：
+
+- 真相先改 `Chunk.blockData`
+- `MemoryWorldStore` 只做 unloaded 接班准备
+- 不再构造完整 `blockDataSnapshot`
+
+### 6.2 Chunk 加载
+
+目标链路：
+
+```text
+World 请求 chunk
+-> 先查 MemoryWorldStore.getChunkRecord()
+-> miss 时回源冷存储或生成器
+-> 回源结果先写入 MemoryWorldStore
+-> Chunk.loadFromRecord()
+-> Chunk.blockData 接管为 loaded 权威
+-> 从 blockData 重建 blockDataArray / solidBlocks / solidBlockIds / lightSourceCoords
+-> Worker 计算 visibleKeys / meshData / AO
+-> Worker 回包只更新派生层
+```
+
+关键约束：
+
+- Worker 不能直接改写逻辑真相
+- `Chunk.blockData` 在加载完成后成为唯一活跃逻辑权威
+
+### 6.3 Chunk 卸载
+
+目标链路：
+
+```text
+World.beforeChunkUnloadSync()
+-> 用当前 Chunk.blockData / runtimeEntities / staticEntities 覆盖 MemoryWorldStore 中对应记录
+-> 释放 visibleKeys / solidBlocks / blockDataArray / meshData / instanceIndexMap / dynamicMeshes
+-> 标记冷存储落盘脏块
+```
+
+关键约束：
+
+- 卸载后仍能 reload 恢复
+- 不再依赖 `pendingUnloadFlushQueue`
+
+### 6.4 Reload / 刷新恢复
+
+目标链路：
+
+```text
+启动
+-> 从 IndexedDB 读取 chunkRecord / regionRecord
+-> 导入 MemoryWorldStore
+-> runtime streaming 时从 MemoryWorldStore 读取
+-> Chunk.loadFromRecord() 接管 loaded 权威
+```
+
+关键约束：
+
+- 先建立世界级内存视图，再进入 runtime streaming
+- 导入 JSON 存档时走 MemoryWorldStore，而不是先走 PersistenceService.cache
+
+### 6.5 手动保存
+
+目标链路：
+
+```text
+保存前先把所有 loaded chunk 同步回 MemoryWorldStore
+-> collectSnapshot() 直接从 MemoryWorldStore 读取
+-> 生成 saveData
+-> 可选异步落盘到 IndexedDB
+```
+
+关键约束：
+
+- 导出文件不依赖当前 `IndexedDB` 状态
+- `collectSnapshot()` 不再逐 chunk 回查 `worldStore.getChunkRecord()`
+
+## 7. Component Responsibilities After Migration
+
+### 7.1 `Chunk`
+
+保留职责：
+
+- 持有 loaded chunk 的 `blockData`
+- 维护所有查询 / 渲染派生层
+- 在单块编辑时驱动派生层增量更新
+- 对 AO / Face Culling / render delta 负责
+
+调整职责：
+
+- `blockData` 注释更新为“完整逻辑块集合”
+- 不再承担持久化快照链的协调逻辑
+
+### 7.2 `MemoryWorldStore`
+
+保留职责：
+
+- 世界级 chunk 索引
+- 已知世界块数据的内存持有
+- chunk unload 后的逻辑状态承接
+- 手动保存与刷新恢复的统一读取入口
+
+调整职责：
+
+- 语义从“并行运行时权威”收窄为“未加载 chunk 的 `blockData` 容器”
+- `dirtyChunks` 只为冷存储落盘服务
+
+### 7.3 `WorldRuntime`
+
+保留职责：
+
+- 冷读取协调
+- 旧档导入辅助
+- region 预取辅助
+- 冷写入调度
+
+删除或退出主链路的职责：
+
+- runtime 期间完整 `blockDataSnapshot` 维护
+- `flushChunk()` 参与运行时正确性
+- `pendingUnloadFlushQueue`
+
+### 7.4 `PersistenceService` / `WorldStore` / `PersistenceWorker`
+
+保留职责：
+
+- 冷存储读写
+- 旧档兼容转换
+- 手动保存或后台落盘
+
+退出职责：
+
+- runtime 主链路权威读取
+- 运行时 blockData snapshot cache
+
+## 8. Migration Strategy
+
+### Phase 1: 语义收敛
+
+- 更新 `Chunk.blockData` 与 `MemoryWorldStore` 的职责定义
+- 不改现有功能行为
+
+### Phase 2: 去掉 runtime blockData 快照链
+
+- 收缩 `WorldRuntime.recordBlockMutation()`
+- 停止构建完整 `blockDataSnapshot`
+- `saveDebounced()` 只标记冷存储脏块
+
+### Phase 3: 保存与导入改读内存权威
+
+- `Game.collectSnapshot()` 改从 `MemoryWorldStore` 读取
+- `Game.applySaveData()` 改直接写 `MemoryWorldStore`
+
+### Phase 4: 收缩旧持久化缓存层
+
+- deprecated `PersistenceService.cache`
+- deprecated `pendingUnloadFlushQueue`
+- 将 `WorldRuntime` 明确降级为冷存储协调器
+
+### Phase 5: 真正评估消息粒度 / 持久化粒度优化
+
+- 区分 `postMessage` 消息体成本与 `IndexedDB.put(regionRecord)` 结构化复制成本
+- 再决定是否推进 chunk 级持久化
+
+## 9. Risks
+
+1. 若过早删除 `PersistenceWorker.regionCache`，旧档冷启动可能退化
+2. 若 `collectSnapshot()` 改读内存后未先同步 loaded chunk，手动保存会漏最新修改
+3. 若错误地删除 `deletedBlockTombstones`，会重新引入晚到 Worker 回包脏写
+4. 若把特殊实体占位强塞进普通 `blockData`，会污染块语义与索引层
+5. 若误把 `blockDataArray` / `solidBlockIds` 当成多余权威副本删除，会导致高频查询性能回退
+
+## 10. Success Criteria
+
+改造完成后，应满足以下判断：
+
+1. 已加载 chunk 的逻辑真相只在 `Chunk.blockData`
+2. 未加载 chunk 的逻辑真相只在 `MemoryWorldStore.chunks[].blockData`
+3. `visibleKeys` / `solidBlocks` / `blockDataArray` 只作为派生索引存在
+4. runtime 正确性不再依赖任何 `blockDataSnapshot` / unload flush queue / PersistenceService.cache
+5. `collectSnapshot()` 与 `applySaveData()` 不再依赖 `worldStore.getChunkRecord()` 或 `PersistenceService.injectSaveData()`
+6. `IndexedDB` 只承担冷存储职责
