@@ -269,6 +271,32 @@ model behind them.
 - **Tests stay per-module.** New tests go into their own file under `test/`
   (zeroerr cases; each case is process-isolated via CTest). Do not grow a
   shared test main.
+- **Examples are a tested surface.** A new `examples/<name>/` must be runnable
+  (`main.nut` + a `config.nut` that assigns the engine `config` table), or be
+  listed with a reason in `scripts/check_examples.py`'s `NON_RUNNABLE_EXAMPLES`;
+  it must own a `README.md` and a row in `examples/README.md`. `make check/examples`
+  (source-quality) enforces that layout, and `scripts/smoke_examples.sh` launches
+  every runnable example in CI for at least `MIN_RUN_SECONDS` (2s) — dying early,
+  exiting non-zero, or printing an error marker fails the job. Run
+  `MIN_RUN_SECONDS=2 bash scripts/smoke_examples.sh <name>` before claiming an
+  example works.
+- **Repository scripts are UTF-8 on every host.** CI runs them on Linux, where
+  stdout/stderr are UTF-8; on Windows a *redirected* stream falls back to the
+  ANSI code page (cp936/GBK on a Chinese Windows), so printing a character that
+  code page cannot encode (`↔`, `²`, `³`, `⇒`, `•`, emoji — all common in this
+  repository) raises `UnicodeEncodeError` and turns a checker into a traceback.
+  The mirror image is input: `Path.read_text()` without `encoding=` decodes
+  UTF-8 repository text as cp936 and raises `UnicodeDecodeError`.
+  - Every `scripts/*.py` program (a module with an `if __name__ == "__main__":`
+    block) calls `utf8_stdio.enable_utf8_stdio()` as the first statement of that
+    block — never at import time, so importing a script module stays free of
+    side effects.
+  - Text file I/O always passes `encoding="utf-8"` explicitly.
+  - Decode a child process with the encoding that child actually writes: `git`
+    output is UTF-8, so its call sites pass `encoding="utf-8"`.
+  - `scripts/tests/test_utf8_stdio.py` enforces all of the above and runs in the
+    CI script-test step; `python3 -X utf8 -m unittest discover -s scripts/tests
+    -p "test_*.py"` is the local equivalent.
 - **PR granularity.** An interface change ships as one PR that updates the
   interface, every backend and every consumer — no intermediate commits that
   break CI. Use `codex/` branch prefixes for agent work.

+# TileWorldCreator 4 核心功能移植到 EVEngine
+
+## 范围
+
+本移植以 `TileWorldCreator 4 v4.3.5.unitypackage` 中的运行时算法、图组合、网格构建和配置语义为
+行为参考，采用 EVEngine 原生 `Grid2D`、`PointSet`、`PointGraph`、`MeshBuild`、Result 与模块句柄。
+“核心功能完成”不包括 Unity Inspector/EditorWindow 外观、Unity Prefab/ScriptableObject 二进制兼容、
+Unity Renderer/Collider 组件或示例美术资产；这些是宿主编辑器与资产格式，不是生成算法本身。
+
+## 功能对应
+
+- Dot Grid → `generate.dot_grid`
+- Cellular Automata → `generate.cellular`
+- Pathfinding → `grid.path`
+- BSP Dungeon → `generate.registry` + `algorithm=dungeon.bsp`；完整 Roguelike 地牢使用
+  `algorithm=level.roguelike`，不在 GridGraph 内维护第二套地牢算法
+- Random Walk Dungeon → `generate.random_walk`
+- Maze → `generate.maze`
+- Height Texture → `Grid2D.detail` 输入与 `select.detail_range`
+- Random Noise → `generate.random_noise`
+- Shapes → `generate.shape`
+- Checkerboard → `generate.checkerboard`
+- Poisson Disc Sampling → `generate.poisson`
+- Add / Boolean / Subtract → `grid.union`、`grid.intersect`、`grid.subtract`
+- Smooth / Expand / Shrink / Invert → 同名 `grid.*` 节点
+- Select / Select by neighbour / Select by rule → `select.random`、`select.neighbors`、`select.rule`
+- Select islands / Find position on islands → `select.islands`、`select.island_centers`
+- Push to paint positions → 图输出的拥有型 `Grid2D`；由调用方显式绑定为下游输入，不使用隐式全局画布
+- Tile preset / neighbour rules → `grid.autotile` 把八邻域 mask 写入 detail；
+  `resolveTilePreset` 按 4.3.5 原表精确解析 14 类标准网格瓦片、旋转、X 镜像和 9 位配置
+- Object build layer → `ObjectBuildLayer` 把 PointGraph 输出转换为带 `asset`、父子关系和完整变换的
+  `PointSet`，支持确定性加权选择、随机变换、朝向层、place-on-top 高度属性和子对象规则
+- Persistent build configuration → `BuildLayerStack` 按插入顺序执行启用的 Tiles/Objects 层，使用
+  `EVPCG_BUILD_LAYERS 1` 与嵌入式 `EVPCG_OBJECT_LAYER 1` 格式原子回读，失败不发布部分 artifacts
+- Incremental build → `IncrementalBuildExecutor` 按固定格子簇缓存 BuildLayerStack artifacts；哈希包含层定义、
+  格子一圈 halo、完整点字段和强类型属性，输出有序 upsert/removal delta，任一簇失败则旧缓存原样保留
+- Tiles build layer / mesh combiner → `mesh.grid_tiles`、`mesh.merge`、`mesh.transform`
+- Grid mesh collider generator → 增量示例从每簇 `MeshBuild` 创建 `World3D` 静态三角网格碰撞体；
+  更新采用先建后换，removal 同步销毁，且 physics provider 缺席时可观察地退化为纯渲染
+- Runtime manager / configuration → Procgen 模块拥有的代际句柄、图 revision、版本 1 定义格式和统一 Result
+
+## 混合调用契约
+
+标准路径为：
+
+`GridGraph -> convert.grid_to_points -> point.subgraph(PointGraph) -> MeshGraph.point.input -> mesh.instance_points`
+
+网格铺砖路径为：
+
+`GridGraph -> grid.autotile -> MeshGraph.grid.input -> mesh.grid_tiles -> MeshBuild/GeneratedArtifact`
+
+跨域只传递拥有型值或显式句柄。连接建立时检查端口类型；修改从节点向下游失效缓存；图实例仅允许
+所属线程访问且不可重入。Grid/Mesh 定义只持久化拓扑与标量参数，场景输入在恢复后重新绑定。
+
+## 确定性与失败语义
+
+随机生成器使用图参数中的命名 seed；相同版本、尺寸、参数和 seed 产生相同网格。图执行成本与访问
+格子数、输出顶点数或“源网格顶点数 × 点数量”成线性关系。无效操作、参数、类型、断开的必需输入、
+环、尺寸不匹配和损坏资产均返回结构化 Result，不使用 `bool + lastError`。
+
+## 验证入口
+
+- `examples/tileworld-graph-dungeon`：可直接运行的资产无关 3D 示例，覆盖注册表 Roguelike 地牢、
+  `select.semantic` 分层、autotile、随机选择、
+  Grid→PointGraph、版本化 BuildLayerStack、PointSet→MeshGraph 实例化，以及边界墙、导航和装饰层；
+  地面与对象场景缓存直接消费 8×8 格子簇的 upsert/removal delta，不再额外执行完整 build stack。
+  同一 delta 还驱动每簇静态三角网格碰撞体的替换/回收。运行时会选取可行走端点、执行
+  `grid.path`，并验证 MeshBuild 上传、空对象簇、热重载和换 seed 重建。
+- `test/procgen_grid_graph.cpp`：生成器、选择器、寻路、autotile、TilePreset 精确配置、Grid→PointGraph、Grid/Point→Mesh、
+  类型拒绝、环、缓存失效和两种定义格式回读。
+- `test/procgen_object_build_layer.cpp`：加权资产、确定性随机变换、朝向、place-on-top、子对象和失败路径。
+- `test/procgen_build_layer_stack.cpp`：层顺序/启用状态、混合 artifact、版本往返、未知字段和损坏配置原子拒绝。
+- `test/procgen_incremental_build.cpp`：稳定缓存、簇内与边界脏区传播、删除 delta、全局坐标网格分片、
+  参数拒绝以及失败时事务回滚。
+- `test/procgen_result_contract.cpp`：Squirrel 创建拥有型 Grid2D 并直接绑定 GridGraph，随后执行
+  GridGraph/MeshGraph 并取得拥有型 MeshBuild，覆盖跨图代理的生命周期与类型契约。
+- `src/modules/procgen/GridGraphAlgorithms.cpp`：独立确定性算法实现。

+# dnut 序列语言与解释器（模块 `dnut_interpreter`）
+
+日期：2026-09-15
+层：**L1**
+源码：`src/modules/dnut_interpreter/`
+清单：`cmake/module_manifest/core_foundation.cmake` 的 `dnut_interpreter` 声明
+
+## 1. 这个模块拥有什么
+
+`.dnut` 是引擎的**作者序列语言**。本模块是它的**唯一 owner**：
+
+| 事实 | 唯一 owner | 说明 |
+| --- | --- | --- |
+| `.dnut` 词法 | `DnutLexer` | 所有方言共用；不变量是「同一文件只有一个词法器」 |
+| 编译产物模型 | `SequenceAsset` / `SequenceNode` / `SequenceRoute` | 通用图模型，节点类型是**字符串**而非闭集枚举 |
+| 步骤词表与字段表 | `StepKindRegistry` | descriptor 是字段的唯一真相源；编译器与作者 UI 都从它派生 |
+| 跨帧执行游标 | `SequenceRuntime` | 调用栈、挂起/恢复、状态捕获、执行预算护栏 |
+| `.dnut` → 资产的编译 | `DnutCompiler` | 只懂控制流关键字；步骤合法性交给注册表 |
+| 条件求值的**契约** | `SequenceConditionOutcome` | 只定义「通过/不通过 + 稳定原因」；条件系统由消费者适配 |
+
+**不拥有**（明确不在本模块）：任何领域语义。`line`/`pool`/`story:move`/`skill` 都是
+**注册项**，不是编译器或运行时里的 `switch` 分支。命令的实际执行、i18n、支付、
+存档格式、表现后端都在各自的模块。
+
+## 2. 对外六个面
+
+| 面 | 内容 | 取证 |
+| --- | --- | --- |
+| 能力入（capability in） | 无。本模块不 `cap::query` 任何接口，也不调用 `getModInst`/`ModuleManager`。消费者直接链接并在自己线程上构造注册表与运行时。 | `grep -n "cap::\|getModInst\|requireModInst" src/modules/dnut_interpreter/*` → 0 命中 |
+| 能力出（capability out） | 无 `cap::provide`。对外契约是**类型与函数**：`lexDnut` / `compileDnut` / `SequenceRuntime` / `StepKindRegistry`。 | 同上；`module_boundary_audit.py --capabilities` 中该模块无条目 |
+| ECS + Link 数据 | 无。本模块不注册 ECS 组件、不注册 Link 种类、不创建实体。 | `grep -n "SystemContract\|LinkKind\|registerLinkKind"` → 0 命中 |
+| 事件 | 唯一出口 `SequenceRuntime::setEventSink`；事件种类 `Started/NodeEntered/Blocked/Stepped/Resumed/Ended/Failed`，同步派发、无锁、不得重入。 | `SequenceRuntime.h` 的 `Event` / `EventSink` |
+| 脚本绑定 | **无 SCRIPT 声明**。脚本面由消费者提供：`rpg` 绑定 `eve.rpg.newStorySession(...)` 等。 | manifest 中该模块无 `SCRIPT` |
+| 工具协议 | 无 MCP/LSP/DAP 方法。 | — |
+
+**跨模块包含**：公共头只包含 `common/Result.h`、`common/Value.h` 和本模块头。
+不包含 `decision`、`dialogue`、`rpg` —— 条件求值通过 `std::function` 契约注入。
+
+## 3. 裁剪声明
+
+- **L1 编译期**：`dnut_interpreter` 的源文件不参与编译时，`dialogue`/`rpg` 的 TU 会
+  因找不到头而失败——它们是**硬依赖**（`DEPS`），不是可选依赖。
+- **L2 链接期**：`rpg` 的 `RpgDialect.cpp` 调用 `compileDnut`、`SequenceRuntime::start`、
+  `StepKindRegistry::registerStep` 等非 inline、非虚函数，产生**未定义符号**，因此
+  关掉本模块后 `EVRPG` 无法链接。这是 `R-BOUND-2` 判据表「调 B 的非虚、非 inline
+  成员函数」一行。
+- **L3/L4**：本模块没有运行时可选性——它要么被编入，要么消费者无法编译。因此
+  不声明 `GROUP`（与 `rpg` 一致，只随完整构建进入），也不需要 present/absent 双 profile。
+- **符号引用证据**：`rpg/RpgDialect.cpp` 对 `eve::dnut::compileDnut(...)`、
+  `eve::dnut::SequenceRuntime::start(...)` 的调用即符号引用；`include` 图不作为判据
+  （`R-BOUND-1`）。
+
+## 4. 语言表面
+
+```
+document   := block*
+block      := 'story' IDENT modifier* '{' statement* '}'
+            | <其他方言的顶层块，直接跳过>
+modifier   := 'repeatable' | 'version' '=' INT
+statement  := step | ifStmt | choiceStmt | 'end'
+step       := IDENT (IDENT '=' value)*
+ifStmt     := 'if' condition block ['else' block]
+choiceStmt := 'choice' '{' ('option' STRING ['when' condition] block)+ '}'
+value      := STRING | NUMBER | 'true' | 'false' | IDENT | '-' NUMBER
+condition  := 比较 / '&&' / '||' / '!' / '(' ')'
+```
+
+- `story` 之外的顶层块（`pool`、`conversation`）被**跳过**，因此一个文件可以同时
+  容纳其他方言而不被本编译器拒绝。
+- 控制流关键字只有 `if` / `choice` / `call` / `wait` / `end`；它们分别下降到
+  `branch` / `choice` / `call` / `wait` / `end` 节点。**步骤类型不是关键字**：
+  `mark`、`skill`、`story:move` 一样由注册表声明。
+- 条件编译为 `eve::Value` 对象：`{var,op,value}`、`{all:[…]}`、`{any:[…]}`、`{not:…}`，
+  `op ∈ eq|ne|gt|lt|ge|le`。**求值器由消费者注入**：语言核心不知道 `switch.x` 是什么。
+
+### 4.1 编译错误恢复
+
+单个语句失败时，编译器同步到下一个可能的语句起点继续，因此一次编译能报出多个
+错误（例如一个块里两处拼写错误会得到 2 条诊断）。**含错误的文档不发布资产**：
+`RpgStoryCatalogue::replaceFromDnutStrict` 在 `hasErrors()` 时保留上一份目录。
+
+## 5. 步骤注册表契约
+
+```cpp
+StepKindDescriptor {
+  type, displayName, category,
+  shape(Instant | Await),
+  fields[{name, type(String|Number|Integer|Boolean|Any), required}],
+  validate(node) -> Result<void>      // 跨字段的领域不变量
+}
+```
+
+- `Instant`：必须绑定 handler；`validate` 会拒绝「instant 但没有 handler」的声明。
+- `Await`：可以**不绑定 handler**，此时运行时挂起、宿主呈现后用
+  `SequenceRuntime::advance()` 确认；绑定了 handler 的 `Await` 可以返回 `Blocked`
+  并在之后用 `resumeStep(value)` 继续。
+- 字段校验是**严格**的：未声明的字段被拒绝。这是刻意的——拼错的字段名不会静默
+  变成一个永远为空的属性。
+- `validate` 是跨字段规则（「`learn` 与 `forget` 恰有其一」）的落点，因此这类
+  错误在**编译内容时**报出，而不是等玩家走到那一步。
+
+### 5.1 `StepContext::host`
+
+语言核心不理解消费者的领域对象。消费者在运行时上装一个不透明指针
+（`setHostContext`），核心原样转发给 handler。`rpg` 用它传 `RpgStoryBinding*`。
+这保持了「核心零领域依赖」，代价是一个需要文档说明的 `void*`。
+
+## 6. 所有权、生命周期与线程
+
+- `SequenceAsset` / `StepKindRegistry` 归调用者所有。`SequenceRuntime` 持有
+  **借用**指针，调用者必须保证它们在运行时存活期内有效。
+- `RpgStorySession` 在 `begin` 时**快照整份目录**，因此热替换不会让活动会话悬垂。
+- `captureState` 存的是**稳定引用**（`asset id` + `version` + `node id` + bindings +
+  locals），不是指针。`restoreState` 通过资产解析器重新解析，并在 `version` 不匹配时
+  明确失败。
+- 所有方法都是**owner 线程专属**，不做同步；事件回调同步派发，且不得重入运行时。
+- 执行预算 `kExecutionBudget = 10000` 是内容写出死循环时的唯一护栏：超预算失败而不是挂死。
+
+## 7. 已知债务（显式登记）

+
+## Update: the `hexmap` module
+
+The hex map was subsequently ported from the Catlike Coding reference project as a
+dedicated module rather than another procgen recipe, because an *editable* map needs
+authoritative cell data and incremental mesh updates that a one-shot generator
+cannot provide. `docs/usr/modules/hexmap.md` is the module contract;
+`examples/hex-terrain-3d` is the interactive editor over it. It deliberately lives
+in its own directory so that `examples/hex-terrain` — the `mesh.hexterrain` proof
+described above — keeps shipping unchanged.
+
+What that closes from the gap list above:
+
+- Gaps 1 and 5 (no cell data, no chunking, no picking): `hexmap::HexMap` owns the
+  cell grid (elevation, water, terrain, feature levels, river/road connections),
+  partitions it into 5x5 chunks with dirty tracking, answers neighbour/edge
+  queries, and converts a world-space ray back to a cell.
+- Gap 5's mesh side: `buildChunkSurfaceMesh` generates the terrain, water, river
+  and road streams per chunk, and `HexMapModule::rebuildChunk` updates only the
+  dirty surfaces in place.
+- Gap 7's "one baked mesh" half: the walkable terrain is now the chunked,
+  independent surface the audit asked for.
+
+What still stands:
+
+- Gaps 2-4 (bindable texture arrays, independent roughness/metallic/AO maps, a
+  CPU-to-GPU `PbrTextureSet`) are unchanged. The example therefore still shades the
+  terrain procedurally from a packed vertex encoding, now three layers instead of
+  two; `HexMapMesh.h` documents that as a compatibility bridge.
+- Gap 6 (production hydrology: basin filling, flow accumulation, confluences) is
+  unchanged. The module enforces the reference's downhill/lake-outflow rule and
+  draws channels, but does not solve drainage.
+- `mesh.hexterrain` and its generator are untouched and still ship the original
+  proof; the module is additive.

+# 实施计划：dnut 序列语言核心（L1）与 RPG 方言
+
+> 上位设计：`docs/dev/superpowers/specs/2026-09-15-dnut-interpreter-l1-design.md`
+> 状态：**已实施**（§1.1 语言核心、§1.2 RPG 词表、§1.3 测试与文档全部落地；
+> §5 角色移动与 §6 动画播放按增量补齐；`SequenceDocument` 与 dialogue 迁移按 §4 登记为后续增量）
+> 目标（用户原话）：给 dnut 语言中的 rpg 方言添加人物的移动、动画播放、对象的选取、
+> 技能的获取、属性的修改、物品、装备获取等等功能——**完整实现**。
+
+## 0. 与设计文档的偏差声明
+
+设计的「阶段 1」把 dialogue 的 conversation 方言整体迁入 L1。本计划**先交付可运行的
+RPG 方言与其 L1 语言核心**，把 dialogue 迁移留作后续增量，理由：
+
+1. 用户目标是**能力**（RPG 方言可表达并可执行），不是模块搬迁本身；
+2. dialogue 迁移会让一个 PR 触及 15 个文件 + 8 个测试文件，把「新能力」与
+   「纯搬迁」混在一次交付里，失败模式不可分离；
+3. 语言核心（词法/资产模型/步骤注册表/运行时）一经建立，dialogue 迁移是**纯消费者改造**，
+   不再需要新机制。
+
+因此顺序为：**语言核心（L1）→ RPG 方言语汇 → RPG 接入与绑定 → dialogue 迁移（后续）**。
+`docs/dev/superpowers/specs/2026-09-15-dnut-interpreter-l1-design.md` §8 的阶段划分
+按此顺序重读：本计划覆盖其阶段 1 的「新模块 + 语言」与阶段 2、3 的 RPG 部分。
+
+## 1. 交付物清单
+
+### 1.1 新模块 `src/modules/dnut_interpreter/`（L1）
+
+| 文件 | 职责 |
+| --- | --- |
+| `DnutDiagnostic.h` | 与领域无关的诊断：`Severity`/`path`/`line`/`column`/`message` |
+| `DnutLexer.h/.cpp` | 统一词法器（今天 `DnutParser.cpp:101-217` 的升格），带行/列 |
+| `DnutBlockScanner.h/.cpp` | 顶层块切分（`story` / `pool` / `conversation`），供多方言共用 |
+| `SequenceAsset.h/.cpp` | 资产模型 `SequenceAsset`/`SequenceNode`/`SequenceRoute` + 图校验 |
+| `StepKindRegistry.h/.cpp` | 步骤类型注册表：descriptor + schema + validate + handler + dispatch |
+| `DnutCompiler.h/.cpp` | 注册表驱动的 `.dnut` → `SequenceAsset` 编译器（控制流核心 + 通用步骤） |
+| `SequenceRuntime.h/.cpp` | 跨帧游标运行时：分支/调用/等待/命令派发/挂起恢复/状态捕获/预算护栏 |
+| `SequenceDocument.h/.cpp` | 作者文档反射（字段表由 `payloadSchema` 派生） |
+
+### 1.2 `src/modules/rpg/` 增补（L1 消费者）
+
+| 文件 | 职责 |
+| --- | --- |
+| `RpgDialect.h/.cpp` | 注册 RPG 步骤词表 + 领域 handler + `.dnut` story 装载门面 |
+| `RPG.cpp` | 脚本绑定：装载、执行、观测 |
+| `StoryEvent.h/.cpp` | 保持 v1 线格式与游标语义；新增 `.dnut` 内容源（不破坏既有 JSON 路径） |
+
+### 1.3 测试与文档
+
+- `test/dnut_interpreter_language.cpp`：词法、块切分、编译、诊断、注册表校验。
+- `test/dnut_interpreter_runtime.cpp`：控制流、挂起/恢复、捕获重建、预算护栏。
+- `test/rpg_dialect.cpp`：七类 RPG 步骤的语义与失败路径。
+- `docs/dev/dnut序列语言与解释器.md`：模块 owner 文档（六面边界 + 裁剪声明）。
+- `docs/usr/modules/rpg.md`：RPG 方言语法与用法。
+
+## 2. RPG 方言（语言表面）
+
+```
+story <id> [repeatable] {
+    move      actor=<id> x=<n> y=<n> [duration=<n>]
+    animation target=<id> clip=<uri> [loop] [hold]
+    select    object=<id> [prompt=<text>]
+    skill     actor=<id> learn=<id>          # forget=<id> 亦为同一步骤的模式
+    attribute actor=<id> name=<id> op=set|add value=<n>
+    item      add=<id> [count=<n>] | remove=<id> [count=<n>]
+    equipment actor=<id> equip=<id> | unequip=<slot>
+    message   text=<text>
+    dialogue  id=<conversationId>
+    wait      duration=<n>
+    camera    x=<n> y=<n> [duration=<n>]
+    if <condition> { ... } [else { ... }]
+    choice { option "label" [when <condition>] -> <target> }
+    call <storyId>
+    end
+}
+```
+
+- 步骤类型**不是**编译器里的 `switch`：`move`/`animation`/... 全部由 `rpg` 注册，
+  编译器只按注册表校验字段。
+- `if`/`choice`/`call`/`end`/`wait` 是语言核心的控制流，编译为 `branch`/`choice`/`call`/
+  `end`/`wait` 节点。
+- 条件沿用 `decision::Condition` 的 `eve::Value` 形态（`var`/`op`/`value`、`all`/`any`/`not`）。
+
+## 3. 验收
+
+```sh
+python3 scripts/check_module_manifest.py
+python3 scripts/module_depgraph.py --check --check-layers
+make build/win32-debug
+build/win32-debug/test/unit_test.exe "dnut_interpreter.*"     # 或用 CTest 过滤
+build/win32-debug/test/unit_test.exe "rpg_dialect.*"
+```
+
+## 4. 未纳入本计划的既有债务（显式登记）
+
+- dialogue 的 conversation/pool 方言尚未迁到 L1 语言核心（设计阶段 1 剩余部分）。
+  迁移前，`.dnut` 仍有两套前端；本计划**不新增第三套**——RPG 方言直接消费 L1 词法器与
+  块切分器，dialogue 的两套方言保持原状，待迁移时统一。
+
+## 5. 增量：角色移动（对设计 §8 阶段 3 的有意偏离）
+
+设计文档 `2026-09-15-dnut-interpreter-l1-design.md` §8 阶段 3 把移动描述为
+「**基于既有 `map::Pathfinder` + 一个按格移动控制器**」。本次交付**不那样做**，
+改为在 `rpg` 侧提供一个宿主注入的移动端口：
+
+```cpp
+struct RpgStoryBinding {
+    …
+    StoryMoveHandler moveActor;   // Result<StoryMoveStatus>(const StoryMoveRequest&)
+};
+```
+
+偏离理由——设计里那条路会把方言**焊死在一种玩法上**：
+
+1. `map::Pathfinder` 是**格子地图**的寻路器。把 `move` 的实现接到它上面，等于规定
+   `actor` 必须是地图上的实体、`x`/`y` 必须是格坐标、移动必须存在一条格子路径。
+   战棋、连续 3D、横版与轨道序列都会被迫先造一张假地图。
+2. `rpg` 是 **L1**，`map` 更高层；直接依赖会新增一条上行依赖，违反
+   `scripts/module_depgraph.py --check-layers` 的判据。
+3. `move` 的真值只有「谁、去哪里、多久」——**怎么走**是玩法的自由度，不是语言事实。
+
+端口形态保留了两个方向的能力：
+
+- **便捷**：装一个 handler，`move` 步骤自动派发，宿主不再需要在循环里写
+  `if (kind == "move")`；返回 `Arrived` 时（瞬移、已在目标点）剧情不挂起。
+- **灵活**：不装 handler 时行为**逐字不变**——仍是宿主呈现步骤，脚本读 payload 后
+  `advance()`。非队伍主体（地图物件、相机、编队）也能移动，`actor` 投影为 null
+  而步骤照常执行。
+
+取舍明说：**本次不提供按格移动控制器**，因此「内容作者想要一条自动绕障的路径」这件事
+仍然没有开箱实现——那是某个具体玩法适配器的职责，应该建在 `map` 之上而不是
+`dnut_interpreter` 或 `rpg` 里。`x`/`y` 的单位与语义由宿主定义并在其文档中写明。
+
+证据：
+
+- `src/modules/rpg/RpgDialect.h`：`StoryMoveStatus` / `StoryMoveRequest` / `StoryMoveHandler`。
+- `src/modules/rpg/RpgDialect.cpp`：`performMove` + `bind("move", performMove)`；无控制器时
+  返回 `Blocked`，与运行时的宿主呈现挂起**观测等价**。
+- `test/rpg_dialect.cpp`：`FakeMoveWorld` 参考端口 + 六条语义/失败/模式无关用例。
+- `test/rpg_dnut_script.cpp`：Squirrel 端到端驱动 `move` 并核对效果。
+
+## 6. 增量：动画播放（与 §5 同构）
+
+§2 的词表早就声明了 `animation`，但只到「编译能过、运行时把它当宿主呈现步骤挂起」为止：
+没有 handler、没有端口、没有测试、没有样例。本次按 §5 已定的同一形状补齐它，理由是
+这两步的**真值形状完全一样**——「谁、播什么、播完没有」，而「怎么播」同样是玩法的自由度。
+
+端口形态：
+
+```cpp
+enum class StoryAnimationStatus { Finished, Playing, Unavailable };
+struct StoryAnimationRequest { targetId, actor, clip, loop, hold };
+
+struct RpgStoryBinding {
+    …
+    StoryAnimationHandler playAnimation;   // Result<StoryAnimationStatus>(const StoryAnimationRequest&)
+};
+```
+
+与 §5 一致的取舍：
+
+- **便捷**：装一个 handler，`animation` 步骤自动派发，宿主不再需要在循环里写
+  `if (kind == "animation")`；返回 `Finished` 时（瞬发、零长 clip）剧情不挂起。
+- **灵活**：不装 handler 时行为**逐字不变**——仍是宿主呈现步骤，脚本读 payload 后
+  `advance()`。特效挂点、UI 元素等非队伍主体也能作为 `target`，`actor` 投影为 null
+  而步骤照常执行。
+- **不绑死**：`clip` 对引擎是不透明字符串，不解析、不加载。接上某个动画栈（骨骼、
+  Sprite、Spine、montage）是宿主适配器的职责，不是 `dnut_interpreter` 或 `rpg` 的。
+
+字段命名修正：§2 原先写 `[await]`，实现与 `docs/usr/modules/rpg.md` 都是 `[hold]`。
+**以 `hold` 为准**——`await` 与步骤形状 `StepShape::Await`（该步骤本来就挂起）语义重复，
+而 `hold`（播完停在最后一帧）才是宿主真正需要的、引擎无法自行推断的信息。本次同步把
+计划书的 `[await]` 改成 `[hold]`。`loop` / `hold` 均按作者原样透传，引擎不解释。
+
+证据：
+
+- `src/modules/rpg/RpgDialect.h`：`StoryAnimationStatus` / `StoryAnimationRequest` / `StoryAnimationHandler`。
+- `src/modules/rpg/RpgDialect.cpp`：`performAnimation` + `bind("animation", performAnimation)`；无控制器时
+  返回 `Blocked`，与运行时的宿主呈现挂起**观测等价**。
+- `test/rpg_dialect.cpp`：`FakeAnimStage` 参考端口 + 七条语义/失败/模式无关用例。
+- `test/rpg_dnut_script.cpp`：Squirrel 端到端驱动 `animation` 并核对效果。

+
+## 1. 背景与现状
+
+### 1.1 `.dnut` 今天是什么（2026-09-15 代码核对）
+
+`.dnut` 已经在，但**一个扩展名下有两套互不相识的前端和两个入口**：
+
+| 方言 | 解析器 | 产物 | 入口 | 依赖 |
+|---|---|---|---|---|
+| `pool { when … speaker: "…" }` | `dialogue/DnutParser.cpp`（真词法分析器 + 递归下降，`tokenize()` 于 `DnutParser.cpp:101-217`） | `DataValue` 根表（`DataValue` 是 `eve::Value` 的别名，`Dialogue.h:34`） | `Dialogue::loadPoolsFromDnut` / `loadPoolsFromDnutFile`（`Dialogue.h:138-140`） | `dialogue/Dialogue.h`（L6） |
+| `conversation … node … when … -> …` | `dialogue/ConversationCompiler.cpp:85-177`（逐行 `words()` 切分，无词法器） | `ConversationAsset`（`Conversation.h:40-75`） | `DialogueFlow::loadFromDnut` / `loadFromDnutFile`（`DialogueFlow.h:100-102`） | `dialogue/Conversation.h`（L6） |
+
+- **「两方言可共存于同一文件」只有一侧成立。** `docs/usr/modules/dialogue.md:169`
+  如此声明，`ConversationCompiler.cpp:129-131` 也确实显式跳过 pool 语法；但
+  `parseDnut` 遇到顶层 `conversation` 块会在 `DnutParser.cpp:414-415`
+  （`expectIdent("pool")`）直接失败。今天 `examples/dialogue/pools.dnut` 与
+  `examples/rpg-classic/data/village-dialogue.dnut` 是两份不同方言的文件，
+  靠两个不同入口分别加载。
+- **conversation 方言的词表是编译期闭集。** 节点种类 `line|branch|choice|call|command|wait|end`
+  硬编码在 `ConversationCompiler.cpp:61-72`；属性名硬编码在
+  `ConversationCompiler.cpp:147-155`（`next/speaker/text/pool/i18n/voice/target/return/result`）。
+  没有任何区块或步骤的注册入口。
+- **作者侧已经有一份手写反射。** `ConversationAuthoring.h` 的
+  `ConversationDocument::getFieldCount/getFieldName/getFieldKind/getField/setField`
+  按节点种类列出可编辑字段——这是「步骤类型描述符」的事实前身，但它是第二份真相源，
+  与 `ConversationCompiler.cpp:147-155` 的属性表各自维护。
+- **控制流与领域焊在同一个类型里。** `ConversationAsset::Node` 同时装
+  `Branch/Choice/Call/Command/Wait/End`（控制流）与 `speaker/text/pool/i18nKey/voice/expression`
+  （对话领域），以及 `PaymentSpec`/`StateMutation`/`CommandRequestKind`（对话事务语义）。
+
+### 1.2 执行与消费现状
+
+- 执行器 `ConversationRunner`（`Conversation.h:78-228`，实现于 `Conversation.cpp`）
+  已经有完整的跨帧游标：`runUntilBlocked`（`Conversation.cpp:167-272`，含
+  `Conversation.cpp:168` 的 10000 步预算护栏）、`advance`（`:398`）、`select`（`:407`）、
+  `selectRouteForTransaction`（`:424`）、`resumeCommand` 双重载（`:373`、`:394`）、
+  `captureState`/`restoreState`（`:296`/`:310`，帧内用 `captureFrame`，`:283-292`）。
+- 消费面**全部在 dialogue 模块内**：`ConversationImporter`（Yarn/Twee）、
+  `ConversationToolchain`（跨资产 lint 与重命名）、`ConversationAuthoring`
+  （`ConversationDocument`）、`ConversationPersistence`（存档 JSON + 版本迁移）、
+  `ConversationLocalization`、`editing/DialogueGraph`、`editor/EditorDialoguePreview`、
+  `DialogueFlow`。模块外只有测试与 `examples/`（`test/dialogue_*.cpp` 共 17 个，
+  其中 8 个直接包含迁移中的头文件；另有 `test/rpg_classic*.cpp`、
+  `examples/rpg-classic/main.nut`）；`src/` 下唯一的跨模块引用是
+  `src/modules/i18n/editing/LocalizationRuntime.cpp` 引用 `DialogueVoice.h`（与本次无关）。
+
+### 1.3 通用机制其实已经齐了，缺的是一个 owner
+
+| 已有能力 | 归属 | 层 | 提供什么 |
+|---|---|---|---|
+| 具名命令描述符 + handler 路由 + 校验 | `action::ActionNotifyRegistry` | L1 | `type + displayName + category + shape(Instant/State) + requiredPayloadFields`；`registerDescriptor`/`registerHandler`/`validate`/`dispatch`；`withBuiltins()` 已含 `presentation:vfx`/`presentation:audio`/`presentation:camera`（`ActionNotifyRegistry.cpp:21-34`） |
+| 表现引用不绑后端 | `action::ActionTimeline` | L1 | 8 条语义轨道、Notify/StateEnter/StateExit、确定性 `sample(previous,current)`；"resources are referenced by URI/type payloads and resolved by downstream adapters"（`ActionTimeline.h:99-101`） |
+| 分支条件 AST | `decision::Condition` | L0 | `All/Any/Not/Compare/HasTag/HasAttribute/HasResource/StateEquals/AuthorityCheck/PolicyCall`（`Condition.h:20`） |
+| 脚本可注册策略 | `policyregistry::PolicyRegistry` | L0 | `ImplementationKind { Builtin, Script, Batch }` + generation 失效 |
+| 宿主中立命令/观测 | `common::IGameplayControlProvider` | L0 | action descriptor 带 `parameterSchema`、command 带 `expectedRevision`、Capability 多 provider |
+| 热重载 | `filesystem::HotReload` + `Runtime::reload(ScriptId)` + 目录原子替换范式 | — | `HotReload.h:19-33`、`Runtime.h:357`、`StoryEvent.h:62` |
+
+### 1.4 rpg 侧只有平铺数据，且够不着 dialogue
+
+- `enum class StoryEventStepKind { Dialogue, Message, Wait, Move, Camera }`
+  （`StoryEvent.h:15`）是编译期闭集，1–128 步线性序列，固定字段
+  `{reference, actorId, x, y, duration}`（`StoryEvent.h:18-25`）；`StoryEvent.cpp:33-58`
+  的 `parseKind`/`kindName` 是唯一的种类真相源。没有分支、循环、标签、公共事件、
+  脚本命令、开关/变量指令、移动路线、动画/音频/画面特效指令，也没有命令注册入口。
+- 执行逻辑在宿主脚本里：`examples/rpg-classic/main.nut:714-753` 用
+  `getStepKind()` 比较 + if/else 链逐条驱动。
+- **决定性约束：`rpg` 够不着 `dialogue`。** `rpg` 是 **LAYER 1**
+  （`core_foundation.cmake:102-103`），`dialogue` 是 **LAYER 6**
+  （`orchestration.cmake:238-241`）。L1 依赖 L6 会被
+  `scripts/module_depgraph.py --check-layers` 判失败。这就是 `StoryEvent` 为何是闭集枚举。
+
+## 2. 问题定义
+
+缺的不是「语言基础设施」，而是三件绑定在一起的事：
+
+1. **一个 owner 负责「作者序列语言 + 跨帧游标 + 场景级控制流」。**
+   `ActionTimeline` 是**单个动作内部**的采样器（无跨帧游标、无分支、无挂起）；
+   `common::IGameplayControlProvider` 是**单条命令**的提交/观测协议（无序列）；
+   `TransitionRunner` 有完整控制流但在 L6 且与对话领域焊死。
+2. **`.dnut` 前端的分裂要收口。** 同一扩展名两套词法、两个入口、两种产物，
+   且「共处一文件」只有半侧成立；新增步骤类型必须改 `ConversationCompiler.cpp:61-72`
+   的闭集。没有统一前端，就不存在「可扩展的语言」。
+3. **`.dnut` 必须对 rpg 可用。** rpg 在 L1，前端与运行时必须在 L1 或更低，
+   否则 rpg 只能继续写第二套闭集枚举。
+
+因此本次工作有三半，缺一不可：
+
+1. **新建**：L1 模块 `dnut_interpreter`，拥有 `.dnut` 前端 + 资产模型 + 步骤类型注册表 + 运行时。
+2. **迁移**：`dialogue` 的 conversation 方言与执行器下沉/改写为它的消费者，
+   领域语义（payment / stateMutations / i18n / voice / 台词池 / UX）留在 dialogue。
+3. **接入**：`rpg` 剧情事件改为该运行时上的注册步骤类型；两个消费者各自只注册词表。
+
+## 3. 设计原则
+
+1. **一个事实一个 owner。** `.dnut` 的语法、资产模型、序列游标、命令派发归
+   `dnut_interpreter`；条件归 `decision::Condition`；命令词表归
+   `action::ActionNotifyRegistry`；持久游标/完成事实/开关变量归 `rpg::GameState`
+   （`StoryEvent.h:61-65` 已确立该契约）；命令的实际执行归各适配器。
+2. **语言不懂领域。** `line` / `pool` / `story:move` / `story:animation` 都是**注册项**，
+   不是编译器或运行时里的 `switch` 分支。`dialogue` 注册 `line` 步骤与 `pool` 块；
+   `rpg` 注册 `story:*` 步骤。
+3. **命令只发意图，不绑表现后端。** payload 一律 URI/type 字符串，沿用
+   `ActionTimeline.h:99-101` 的既定原则。sprite / Spine / 3D skeletal / Live2D
+   的差别落在 handler 实现上，换后端不改脚本。
+4. **运行时不断言品类。** 它只推进游标、求条件、派发步骤；宿主边界靠
+   `GameState` 游标 + 适配器注册，因此俯视 tile RPG / HD2D / 3D 动作共用同一份脚本。
+5. **保语义搬迁。** 挂起/恢复、事务化选择、状态捕获三处逐字保语义（§5.5），
+   不顺手重构；`.dnut` 既有源码的**接受集不变**（§5.9）。
+6. **可重载。** 沿用已证范式：严格校验 → 原子替换目录 → 活动会话持定义副本 →
+   事件内存档后重放未确认步骤。

+
+## 5. 详细设计
+
+### 5.1 归属判据：逐文件/逐类型的迁移表
+
+`dialogue` 现有 33 个文件按归属分类（依据：`Conversation*`/`Dnut*` 的 `#include` 图与类型用法）：
+
+| 今天的文件/类型 | 归属 | 理由 |
+|---|---|---|
+| `DnutParser` 的 `tokenize()`（`DnutParser.cpp:101-217`） | **L1** | `.dnut` 词法，两种方言共用 |
+| `ConversationCompiler`（语句解析、`nodeKind`、`attributes`、`lintConversations`） | **L1** | conversation 方言的语法与图校验；节点种类改由注册表解析 |
+| `ConversationAsset` / `Node` / `ConversationRoute`（`Conversation.h:22-75`） | **L1** | 通用资产模型；领域字段改入 `payload` |
+| `ConversationAsset::validate`（`Conversation.cpp:23-65`） | **L1 + dialogue** | 通用图校验（id/入口/引用）归 L1；`payment`/`stateMutations` 的「仅 command/choice 可用」规则归 dialogue 的步骤校验 |
+| `ConversationRunner`（`Conversation.h:78-228`、`Conversation.cpp:67-459`） | **L1** | 纯控制流 + 游标（§5.5 三处逐字保语义） |
+| `ConversationRunner::CommandResult/Event/CommandHandler` | **L1** | 通用命令与事件类型 |
+| `CommandRequest`/`CommandResponse`/`CommandRequestKind`（`DialogueState.h:23-58`） | **L1（通用部分）+ dialogue（领域字段）** | `name/arguments/bindings/locals` 通用；`kind/payment/stateMutations` 是对话事务语义，留 dialogue |
+| `toCanonicalValue`/`toDialogueStateValue`（`DialogueState.h:65,72`） | **dialogue** | 对话侧 legacy 值转换，L1 不引用 |
+| `ConversationPersistence` 的 `ConversationSaveMigrations` | **L1** | 只依赖「资产 id + version + 节点 id 映射」，与领域无关 |
+| `ConversationPersistence` 的 StateValue↔JSON | **dialogue** | 对话存档格式 |
+| `ConversationToolchain`（跨资产 lint、`renameConversationAsset/Node`） | **L1** | 全是对资产图的操作 |
+| `ConversationAuthoring`（`ConversationDocument`） | **L1** | 手写字段反射正是步骤描述符的 `payloadSchema`；保留即第二真相源 |
+| `ConversationImporter`（Yarn / Twee） | **dialogue** | 外部对话格式到 `line` 步骤的映射是对话领域知识；产物是 L1 资产 |
+| `ConversationLocalization` / `ConversationText` / `DialoguePayment` / `DialogueState` / `Dialogue.{h,cpp}` / `DialogueUX` / `DialogueVoice` / `editing/DialogueGraph` / `editor/EditorDialoguePreview` | **dialogue** | 领域载荷、本地化、表现与作者 UI |
+| `DialogueFlow`（`DialogueFlow.h:33-232`） | **dialogue** | 脚本门面；内部改为持有 L1 运行时并注册 `line` 步骤 |
+
+### 5.2 资产模型
+
+```text
+SequenceAsset {
+  id, version, entry, parameters[],
+  nodes[]: SequenceNode { id, type, next, payload, routes[] }
+}
+SequenceRoute { label, condition, target, payload }
+```
+
+- `type` 是**字符串**步骤类型名（`line` / `branch` / `choice` / `call` / `command` / `wait` /
+  `end` / `story:move` / …），不再是闭集枚举。
+- `payload` 是 `eve::Value::Object`：步骤类型自己的字段，由该类型的 descriptor 校验与解释。
+  `line` 的 `speaker/text/pool/i18n/voice/expression`、`command` 的 `arguments/payment/stateMutations`、
+  `choice` 的每条路由 `payment/stateMutations` 都进 payload。
+- `condition` 沿用 `eve::Value`（今天 `ConversationRoute::condition` 即如此，`Conversation.h:25`）。
+
+**为什么不让 `ConversationAsset` 留在 dialogue 与 L1 资产并存。** 并存就是同一份内容的两份
+表示，正是本次要消除的「第二套控制流」；而且运行时的 `dispatch` 必须把 payload 交给**领域
+注册的 handler**，L1 不可能知道 dialogue 的强类型结构，所以运行时一侧本来就必须接受弱类型
+payload。既然运行时已经弱类型，资产再强类型只会多一次同步。dialogue 侧改为**无状态的
+payload 编解码**（`decodeLinePayload(node)` 返回强类型视图），不持有第二份资产。
+
+**拒绝的替代方案**：L1 定义资产**接口**（`ISequenceAsset` + 视图），dialogue 保留具体强类型资产
+实现它。好处是 dialogue 侧改动小；坏处是每个领域字段都要走一次虚函数取值，且「步骤类型
+的字段表」这个通用事实仍留在 dialogue，`ConversationDocument` 的手写反射也留着。故不采用。
+
+### 5.3 步骤类型与块类型注册表
+
+复用 `ActionNotifyRegistry` 已证明的形态（`ActionNotifyRegistry.h:19-71`），不新造机制：
+
+```text
+StepKindDescriptor {
+  type, displayName, category,
+  shape(Instant | State | Await),      // Await = 阻塞直到宿主 ack
+  payloadSchema,                       // 字段表：同时供编译器严格校验与作者 UI 反射
+  validate(payload) -> Result<void>    // 领域不变量（如 payment 只允许出现在 command/choice）
+}
+registerStep(type, descriptor, handler) / unregisterStep(type)
+validate(node) / dispatch(node, context)
+```
+
+- `conversation` 块本身由 L1 编译；`pool` 块在阶段 1 仍由 dialogue 的池解析器消费，
+  但**共用 L1 的词法器与顶层块切分**（`DnutBlockScanner`）。块类型的完整注册入口
+  （`BlockKindRegistry`）列为后续增量，见 §11。
+- `dialogue` 注册 `line`（Await）与 `choice` 的领域校验；`rpg` 注册 `story:*`（§4）。
+- 适配器注册命令：`avatar`/`animation`/`map`/`audio`/`ui` 各自实现
+  `presentation:*` / `movement:*` 的 handler。
+- `ConversationDocument` 的 `getFieldName/getFieldKind` 反射（`ConversationAuthoring.h`）
+  由 `payloadSchema` 派生，消除第二份字段表。
+
+### 5.4 控制流集合
+
+**本设计交付**（与今天 `ConversationRunner` 等价，纯搬迁）：
+
+```text
+Branch   取第一条条件通过的 route，否则 next          （Conversation.cpp:184-189）
+Call     压栈 + 切入被调用资产 + bindings mergeDefaults + 结束帧时弹栈恢复（:204-225）
+Command  派发具名命令；Blocked → blocked_ + waitingCommand_；Failed → 失败（:226-268）
+Wait     阻塞，等宿主 advance                          （:181-183）
+End      栈空则 Ended + stop，否则弹栈回到 returnNode  （:190-203）
+```
+
+**后续增量**（不在本设计交付，但 owner 已就位）：
+`Loop / BreakLoop / Label + Jump / CallCommonEvent / Parallel`。
+
+### 5.5 必须逐字保语义的四处
+
+1. **双重重载**：`resumeCommand(StateValue)`（`Conversation.cpp:373`）与
+   `resumeCommand(eve::Value)`（`Conversation.cpp:394`）。L1 运行时**两个都保留**，
+   不做「只留 canonical 版本 + dialogue 加转换壳」的改写。理由：`common/StateValue.h`
+   是 L0 且 L1 已有直接使用先例（`src/modules/rpg/RpgState.h:3`）；保留双载 = 零转换
+   = 零行为变化，引入转换壳反而制造一条需要单独证明等价的新路径。
+   `toCanonicalValue` / `toDialogueStateValue`（`DialogueState.h:65,72`）留在 dialogue，不被 L1 引用。
+2. **事务化选择**：`selectRouteForTransaction`（`Conversation.cpp:424-459`）与
+   `DialogueFlow.cpp` 的支付/状态事务包装。运行时的 `select` 必须保持
+   「选中即提交、失败保持游标」的现状语义（`:445-455` 的 capture → enter → restore 序列），
+   事务包装留在 dialogue。
+3. **调用栈重建**：`captureState` 存的是 `{asset id, asset version, node, bindings, locals}`
+   （`Conversation.cpp:283-292`、`:296-308`），即**稳定引用而非指针**。L1 必须延续这个形态
+   （含 version 校验，`:327-329`、`:346-353`），不得简化成裸 id。
+4. **`advance` 对 choice 的拒绝**：`advance` 在 choice 节点必须返回
+   "select a choice route instead"（`Conversation.cpp:401-402`），不能被通用化掉。
+
+另外 `runUntilBlocked` 的 10000 步执行预算（`Conversation.cpp:168`）必须保留——
+它是脚本内容写错死循环时的唯一护栏，属于通用行为。
+
+### 5.6 命令请求与响应
+
+通用层（L1）——值类型与今天逐字一致，不引入新转换：
+
+```text
+SequenceCommandRequest  { name, arguments, bindings, locals }   // 全部 eve::Value，同今天 CommandRequest
+SequenceCommandResponse { Status(Completed|Blocked|Failed), value, error }
+SequenceCommandHandler  = std::function<SequenceCommandResponse(const SequenceCommandRequest&)>
+```
+
+帧内 bindings/locals 继续用 `eve::StateValue`（今天 `ConversationRunner::Frame` 就是这样），
+与 canonical `eve::Value` 的边界保持今天的模样：命令请求/响应走 `eve::Value`
+（`CommandRequest` 今天即如此，`DialogueState.h:39-41`），legacy handler 走 `StateValue`
+（`Conversation.h:97` 的 `CommandHandler` 今天即如此）。
+
+dialogue 侧保留领域扩展（`CommandRequest` 继续带 `payment` / `stateMutations` / `kind`，
+`DialogueState.h:36-46`），由 dialogue 注册的 handler 做适配转换。
+**不得**把 `PaymentSpec` / `StateMutation` 提到 L1——它们属于 dialogue 的事务语义。
+
+### 5.7 挂起、事件与条件
+
+- 挂起：`Blocked` → `blocked_ = true` + `waitingCommand_ = true` → 宿主
+  `advance()` 或 `resumeCommand(value)` 继续。语义不变。
+- 事件：运行时发出通用事件（`Started/NodeEntered/Command/Ended/Failed`）；
+  步骤 handler 发出领域事件（`Line/Choice/…`）。`setEventSink` 保持单一出口。
+- 条件：`setConditionEvaluator` 继续委托 `eve::decision::ConditionResult`，
+  dialogue 侧的 legacy 分支表达式兼容路径（`evaluateRoute`，`Conversation.cpp:140-165`）
+  留在 dialogue 的 evaluator 实现里。
+
+### 5.8 热重载与存档迁移
+
+沿用 `StoryEvent` 已证范式（`StoryEvent.h:61-65`、`docs/usr/modules/rpg.md:274-276`）：
+
+- 内容目录严格校验 + 原子替换，失败保留上一份。
+- 活动会话持**定义副本**，所以目录热替换不产生悬垂引用。
+- 捕获的状态用**稳定 id + version** 引用资产，恢复时按新定义重新解析（§5.5 第 3 点）。
+- 存档迁移 `SequenceSaveMigrations` 的规则全是资产级事实
+  （`ConversationPersistence.h` 的 `Rule{assetId, fromVersion, currentAssetId, nodes}`），随之下沉。
+- 事件中存档 → 读档后重放尚未确认的步骤（`examples/rpg-classic/main.nut:1967-1998`
+  已有该行为雏形）。
+- 脚本侧热重载沿用 `filesystem::HotReload` + `Runtime::reload(ScriptId)`，本设计不新增重载机制。
+
+### 5.9 语言兼容性契约
+
+前端下沉是**改写**而非移动（今天的 conversation 方言没有词法器，pool 方言有），
+因此验收必须钉住「接受集不变」：
+
+- 现有 `.dnut` 源码（`examples/dialogue/pools.dnut`、
+  `examples/rpg-classic/data/village-dialogue.dnut` 及测试内联源）必须编译出**等价资产**：
+  相同的 `id`/`version`/`entry`/`parameters`、相同的节点 id 与类型、相同的路由与目标、
+  相同的诊断（`ConversationDiagnostic` → L1 `DnutDiagnostic`，字段逐字保留：
+  severity/path/line/message）。
+- **行为改善处需显式声明**：今天是 `parseDnut` 无法读含 `conversation` 块的文件
+  （`DnutParser.cpp:414-415`），统一前端后两种方言可在同一文件被同一入口读入。
+  这是有意扩大的接受集，必须在文档与测试中写明，不能作为「无声兼容」。
+- 语法收紧要禁止：不得因为改写而拒绝今天能编译的源。
+
+## 6. 分层影响与模块声明
+
+- **新建 L1 模块 `dnut_interpreter`。** 声明插入
+  `cmake/module_manifest/core_foundation.cmake` 的 `# L1 -- sensing/action protocol`
+  段（`:133`）内、`action` 声明块（`:145-147`）之后、`# L2 -- combat resolution`
+  （`:148`）之前——`scripts/check_module_manifest.py:216-227` 要求声明必须落在匹配的
+  `# L<n>` 段内。
+- **声明形态**：
+
+  ```cmake
+  # .dnut authored-sequence language, compiler, step-kind registry and cross-frame
+  # interpreter. Domain vocabularies (dialogue lines/pools, RPG story steps) are
+  # registered by their owning modules; this core never interprets a domain payload.
+  eve_declare_module(NAME dnut_interpreter LIB EVDnutInterpreter LAYER 1
+                     SCRIPT DnutInterpreter SLOT dnutInterpreter
+                     DEPS decision
+                     GROUP minimal 2d 3d web)
+  ```
+
+  `GROUP` 取值见 §11 待决问题 3；`SCRIPT`/`SLOT` 见 §11 待决问题 4。
+  `LIB`+`SCRIPT` 同时使用有先例：`rpg LIB EVRPG LAYER 1 SCRIPT RPG`（`:102`）。
+- **依赖合法性**：`dialogue`（L6）→ `dnut_interpreter`（L1）、`rpg`（L1）→
+  `dnut_interpreter`（L1）都是合法下行/同层依赖；`scripts/module_depgraph.py:179`
+  明确「Same-layer edges (e.g. window -> image) are allowed」，同层先例是
+  `rpg`（L1）→ `action`（L1）。`dnut_interpreter` 不依赖 dialogue/rpg，无环。
+- **`rpg` 的依赖声明**：`core_foundation.cmake:102-103` 的 `DEPS` 增加 `dnut_interpreter`。
+- **`dialogue` 的依赖声明**：`orchestration.cmake:238-241` 的 `DEPS` 增加 `dnut_interpreter`。
+  `dialogue` 无 `GROUP`，加依赖不改变任何裁剪档位。
+- **裁剪影响**：`dnut_interpreter` 的消费者（`dialogue`/`rpg`）都不声明 `GROUP`，
+  因此它不应声明 `GROUP`（§11 待决问题 3）；若声明 `GROUP minimal 2d 3d web`
+  会被每个裁剪档无条件编入。裁剪声明按 AGENTS.md 要求给出层号与符号/构建证据。
+
+## 7. 影响面清单
+
+**新增**
+
+- `src/modules/dnut_interpreter/`：`DnutLexer`、`DnutBlockScanner`、`DnutCompiler`、
+  `DnutLint`、`SequenceAsset.h`、`StepKindRegistry`、`SequenceRuntime`、`SequenceDocument`、
+  `SequenceSaveMigrations`。
+- `test/dnut_interpreter_sequence.cpp`（控制流 + 挂起/恢复 + 捕获重建 + 预算护栏 + 注册表校验）、
+  `test/dnut_interpreter_language.cpp`（词法/块切分/编译/lint/方言共处 + 诊断保真）。
+  测试按 AGENTS.md 独立成文件，不进共享 test main。
+
+**迁移（dialogue 内）**
+
+- `DnutParser` 的 `tokenize()`（`DnutParser.cpp:101-217`）→ L1 `DnutLexer`；`parseDnut` 保留在
+  `dialogue`，改为消费 L1 词法与顶层块切分。
+- `ConversationCompiler.{h,cpp}`、`Conversation.{h,cpp}`、`ConversationToolchain.{h,cpp}`、
+  `ConversationAuthoring.{h,cpp}`、`ConversationPersistence` 的迁移部分 → L1。
+- `ConversationImporter.{h,cpp}`、`ConversationLocalization.{h,cpp}`、`ConversationText.{h,cpp}`、
+  `DialogueFlow.{h,cpp}`、`dialogue/editing/DialogueGraph*`、`dialogue/editor/*` → 改为消费 L1 资产模型。
+- `DialoguePayment.{h,cpp}`、`DialogueState.{h,cpp}`、`Dialogue.{h,cpp}`、`DialogueUX.*`、
+  `DialogueVoice.*` → 原地不动（领域语义）。
+
+**测试**：`test/dialogue_conversation.cpp`、`test/dialogue_compiler.cpp`、
+`test/dialogue_proc.cpp`、`test/dialogue_toolchain.cpp`、`test/dialogue_authoring.cpp`、
+`test/dialogue_persistence.cpp`、`test/dialogue_localization.cpp`、`test/dialogue_importers.cpp`
+跟随类型变化；`test/rpg_classic.cpp:242`、`test/rpg_classic_playthrough.cpp:130` 直接使用
+`compileDnutConversations`，需改为 L1 入口。
+
+**文档**：新增 `docs/dev/dnut_interpreter 序列语言与解释器.md`（模块 owner 文档，
+六面边界与裁剪声明写在这里）；更新 `docs/usr/modules/dialogue.md:168-180,275`（`.dnut` 语法
+与 `loadPoolsFromDnut` 的归属指针）、`docs/dev/对话与Avatar模块设计.md:220`（`.dnut` 内容格式的
+owner 变更）、`docs/dev/战斗系统与动作编辑器.md`（`action` 仍是单动作管线，序列语言不在其中）、
+`docs/usr/MODULES.md:75`（若新模块有用户文档则登记）。
+
+**示例**：`examples/dialogue/main.nut:133-135`（`loadPoolsFromDnutFile` 热重载路径）、
+`examples/rpg-classic/main.nut:439-442,573`（`dialogueFlow.loadFromDnut`）在阶段 1 保持可用，
+但内部路径改为 L1 前端。
+
+## 8. 分阶段落地
+
+1. **模块与语言（阶段 1，一个 PR）**：新建 `dnut_interpreter`（词法 + 块切分 + conversation
+   编译/lint + 资产模型 + 步骤类型注册表 + 运行时 + `SequenceDocument` + 迁移），
+   并**在同一个 PR 内**把 `dialogue` 全部消费者切过去（§7）。
+   验收 = 现有 dialogue/rpg 测试全绿 + §5.9 的接受集契约。
+   AGENTS.md 的「接口变化一个 PR」要求不留中间破坏 CI 的 commit，所以阶段 1 不能只做一半。
+2. **rpg 接入（阶段 2，一个 PR）**：`StoryEvent` 改用通用运行时；注册五个既有步骤类型；
+   保持 `eve.rpg.story-events` v1 的线格式与游标语义完全兼容；宿主脚本
+   `examples/rpg-classic/main.nut:714-753` 的 if/else 链退役。
+3. **补表现命令（阶段 3）**：`story:animation`、`story:expression`、`story:wait-for-motion`、
+   移动路线（基于既有 `map::Pathfinder` + 一个按格移动控制器；
+   `docs/dev/2.5D-tilemap-developer-evaluation.md:61` 已记录该缺口）。
+4. **补控制流与脚本扩展面（阶段 4）**：`Loop / Label+Jump / CallCommonEvent / Parallel`，
+   块类型注册入口 `BlockKindRegistry`，脚本侧注册步骤/块的能力，以及 lint 与 i18n 抽取的扩展。
+
+阶段 1、2 是「不改内容格式」的架构收敛；阶段 3、4 是可交付能力，各自独立 PR。
+
+## 9. 验收与门禁
+
+阶段 1 的机械验收：
+
+```sh
+python3 scripts/check_module_manifest.py          # 新声明落在 L1 段内、目录存在
+python3 scripts/module_depgraph.py --check-layers # L1 不出现对 L6 的依赖
+ARCHITECTURE_BASE=HEAD make check/architecture-contracts
+make check/quality-metadata
+git clang-format                                   # 只格式化改动行
+```
+
+行为保持验收（必须覆盖 §5.5 的四处）：
+
+- `resumeCommand`：`Blocked` → `advance`/`resumeCommand` → 继续的两条路径行为不变。
+- `selectRouteForTransaction`：成功提交与失败保持游标两种情况不变；
+  `advance` 在 choice 上仍拒绝。
+- `captureState`/`restoreState`：含 0 层与多层调用栈、bindings/locals 保真、
+  asset version 不匹配时明确失败。
+- 执行预算护栏：构造超长/自环内容必须仍以预算耗尽失败，不挂死。
+- 语言接受集：§5.9 的等价性用例（既有源 → 等价资产 + 等价诊断）。
+
+契约条目：本设计改变的是「谁拥有 `.dnut` 的语法、序列游标与命令派发」，属可执行的
+`state-owner` 与 `api-lifetime` 范围，按需在 `scripts/architecture_contracts.json` 补齐条目。
+
+> **门禁陷阱（已核对，勿踩）：** AGENTS.md 要求新模块补 `module-interface` catalogue 条目，
+> 但 `scripts/check_architecture_contracts.py:47-58` 的 `RULES` 里没有 `module-interface`
+> （实际为 `api-shape`/`link`/`state-owner`/`ecs-system`/`time-rng`/`api-lifetime`/`persistence`/
+> `optional-capability`/`backend-contract`/`debt-metadata` 十项），写这种条目会被判
+> `rule must be one of …` 直接失败（`docs/dev/2026-09-15-模块边界审查台账.md:199`
+> 也确认该机制尚未存在）。本设计**不**往 `architecture_contracts.json` 写非法 rule；
+> 新模块的六面边界写进它的 owner 文档，并用可执行的 `state-owner`/`api-lifetime` 条目表达。
+
+## 10. 非目标
+
+- 不改变 `eve.rpg.story-events` / `eve.dialogue.*` 的既有线格式与存档兼容性。
+- 不把 `PaymentSpec` / `StateMutation` / i18n / voice / 台词池等 dialogue 事务语义提到 L1。
+- 不做脚本侧动态注册原生控制流（`std::function` 无法跨 C++/Squirrel）；脚本侧仍只可注册
+  策略与命令 handler，控制流由 C++ 拥有。
+- 阶段 1、2 不新增任何面向玩家的能力，只做架构收敛。
+- 不把 `action::ActionTimeline` 的语义轨道采样并入本模块（动作内采样器与场景级序列是
+  两个粒度，各自保留）。
+
+## 11. 待决问题（实施前需定）
+
+1. **payload 的值类型**：建议统一用 canonical `eve::Value::Object`（与 `CommandRequest` 一致）。
+   代价是 `Node::arguments` 今天存 `StateValue`，payload 化后需要在边界转换；
+   必须用 §5.5 的双重重载与等价测试证明零行为变化。
+2. **`pool` 块的处理深度**：本设计取「阶段 1 共用 L1 词法与顶层块切分，池语法解析仍归
+   dialogue」；完整方案是 `BlockKindRegistry` 让块类型成为注册项（阶段 4）。
+   若实施中发现共享词法不足以表达池语法的行敏感属性（`parseAttrs` 用 `cur().line` 判定，

+（`.dnut` 语法、资产模型、序列游标与命令派发的 owner 从 L6 移到 L1）、
+**公共契约变更**（`ConversationAsset`/`ConversationRunner` 被取代）、
+**依赖方向变更**（`dialogue` → `dnut_interpreter`、`rpg` → `dnut_interpreter`）、
+**源码真相源迁移**（语言前端与作者反射从 dialogue 迁到 dnut_interpreter）。
+实施完成后应补一条 ADR，并在 baseline 同步时回答：
+`action` 是否仍是「单动作生命周期」的唯一 owner（本设计回答：是），
+以及 `dnut_interpreter` 是否同时承担了「语言」与「运行时」两个职责而需要再切分（待验证）。

+通过 `Model3D` 解码 URI，并为每个网格创建真实 `Renderable3D`；同 URI 回收后复用 ECS 实体和 GPU 资源，
+但逻辑 lease 每次回收都会递增 generation，旧 lease 不能再更新新实例。运行时在 Enter 解析骨骼/目标世界姿态，
+Update 按 attachment 模式同步，Exit/interrupt 对 `recycle_on_block_exit` 隐藏回池；`custom_duration` 按注入的
+action `Duration` 维护到期，`independent` 则脱离动作块并保持可见。provider 缺失时 descriptor 仍可编辑，
+dispatch 明确返回 `NotFound`。独立实例通过 `IActionPrefabInstances` 暴露拥有型检查记录和 generation-qualified

+# 程序化道路系统设计
+
+日期：2026-09-17
+状态：MVP 已落地（`src/modules/procgen/road/`）
+存放：`docs/dev/`
+
+## 目标
+
+在**不使用预制道路/桥梁模型**的前提下，用数学函数生成与参考图一致的视觉层：
+
+1. **几何**：多高程道路、桥面、侧栏、人行道、桥墩
+2. **逻辑贴图**：沿弧长/横向 UV 的车道线、斑马线、导向箭头
+3. **导航网络可视化**：车道中心线与路口转弯弧（青/绿叠加）
+
+全部由 `SplinePath` 平行输运帧 + 截面挤出 + 图论车道图合成，运行时可烘培为 `MeshBuild`。
+
+## 非目标（MVP）
+
+- 完整路口 CSG 布尔融合（用路口平台 + 边端收缩近似）
+- 地形挖填 / 贴地切割
+- 真实交通仿真与 AI 寻路驱动
+- 中文「道路编辑」产品化编辑器面板（文档预留工具流，运行时先配方 + 示例）
+
+## 与现有能力的关系
+
+| 复用 | 角色 |
+|------|------|
+| `SplinePath` / `sampleFramesResult` | 中心线与 Frenet 式截面帧 |
+| `MeshBuild` 命名 group | `asphalt` / `curb` / `sidewalk` / `deck` / `pier` / `marking` / `nav` |
+| `MeshRecipeRegistry` | `mesh.roadNetwork` 配方入口 |
+| `TextureRecipeRegistry` | `tex.roadMarkings` 逻辑贴图 |
+| `urban` 街道 | 可选上游 2D 中心线；本系统是 3D 车道域 |
+
+**不**新建顶层 `road` 模块目录；算法作为 `procgen` 宿主内的 `road/` 卫星（同 `urban/`）。
+
+## 数据模型
+
+```text
+RoadNetwork
+  nodes[]:  RoadNode { id, position, junctionRadius }
+  edges[]:  RoadEdge {
+      id, from, to,
+      controlPoints[] → SplinePath (catmullRom),
+      lanesForward, lanesBackward,
+      style (laneWidth, curb, sidewalk, deckThickness, pier*),
+      elevated (bool | height threshold)
+  }
+  laneLinks[]:  at a node, (inEdge, inLane) → (outEdge, outLane)
+```
+
+权威所有者：`RoadNetwork` 拥有节点/边/车道连接；烘培结果是无指针快照（`MeshBuild` + `RoadOverlay` 折线）。
+
+## 数学管线
+
+### 1. 截面剖面 `RoadProfile`
+
+在边局部 `(side, up)` 平面构造折线剖面：
+
+```text
+[-W/2-sidewalk-curb … asphalt lanes … +W/2 …]
+```
+
+每个区段带 material tag，挤出时写入对应 triangle group。桥面在 `up` 负向加 `deckThickness` 底板。
+
+### 2. 边挤出 `RoadBake::bakeEdge`
+
+1. 边控制点 → `SplinePath`，弧长均匀采样帧
+2. 在路口半径处裁剪端点参数，避免与路口平台重叠
+3. 沿帧挤出剖面（开剖面条带 + 底板可选）
+4. 若帧高度 > `pierClearance`，按 `pierSpacing` 放置轴对齐桥墩盒子
+5. 车道标线：在沥青表面上偏移的薄带（白边线、黄虚中线、斑马带）
+
+UV：`u = normalized arc length`，`v = normalized lateral`（逻辑贴图与虚线周期均依赖此约定）。
+
+### 3. 路口平台
+
+对度数 ≥ 2 的节点，用入射边端点左右路肩点构成凸包近似平台，扇形三角化；斑马线沿入射方向铺条。
+
+### 4. 导航叠加 `RoadOverlay`
+
+- 每条车道：中心线偏移 `±(i+0.5)*laneWidth` 的折线
+- 路口：同节点合法 `laneLinks` 用三次 Hermite 弧连接
+- 箭头：沿折线按弧长放置小三角 mesh（group `nav`）
+
+### 5. 逻辑贴图 `tex.roadMarkings`
+
+纯函数 `(u,v) → RGBA`：沥青底色 + 边线 + 周期虚线 + 可选斑马/箭头 mask。与几何 UV 对齐，可独立预览或烘焙。
+
+## 编辑工具流（产品映射）
+
+与参考图底部工具栏对齐的**语义阶段**（实现可后挂 `procgen_editing`）：
+
+| 阶段 | 文档操作 | 运行时对应 |
+|------|----------|------------|
+| 道路编辑 | 增删边控制点 | `RoadEdge.controlPoints` / SplinePathDocument |
+| 岔路编辑 | 节点连接、匝道 | `RoadNode` + 边拓扑 |
+| 导航网络 | 生成 laneLinks / overlay | `buildNavigation` |
+| 调整车道 | lanesForward/Backward、laneWidth | `RoadStyle` |
+| 烘培模型 | bake → MeshBuild | `bakeRoadNetwork` / `mesh.roadNetwork` |
+| 样式编辑 | 剖面与材质色 | `RoadStyle` + `tex.roadMarkings` |
+
+## API 契约
+
+- 失败路径一律 `Result<T>` / recipe `bool + error`；禁止 `lastError`。
+- 烘培同步、owner-thread-only；返回值不持有对 `RoadNetwork` 的指针。
+- Schema：`eve.procgen.roadNetwork` v1（后续 Document 化时沿用）。
+
+## 验证
+
+- 单元：剖面宽度、挤出顶点/组、桥墩触发、导航折线非空、配方确定性
+- 示例：`examples/procedural-road` 烘培立交并画导航折线
+- 架构：仍落在 `procgen` 宿主内，无向上 `#include`
+
+## 后续迭代
+
+1. 路口 curb return / 真正的 mesh stitch
+2. `RoadNetworkDocument` + gizmo（复用 SplinePathGizmo）
+3. 地形 conform + 走廊 mask
+4. 与 `urban` 中心线自动导入

+# Combat
+
+Combat 模块提供不依赖具体角色类的伤害、韧性、战斗属性、标准 Ability 原型与移动适配。游戏仍负责角色
+实体、动画和输入映射；模块不会创建通用 Actor 根类。
+
+脚本入口 `eve.Combat()` 提供 `getName`，并可通过 `newRuntime()` 创建一个 Squirrel-owned
+`CombatRuntime`。`registerFighter`、
+`setMoveIntent`、`navigateTo`、`stop`、`advance`、`applyDamage`、`applyTimelineDamage` 和 `state`
+全部返回统一 Result 投影；`applyTimelineDamage` 直接消费 Montage runtime event 的 payload JSON，并复用
+`ActionDamageBinding` 校验，不会在示例脚本中复制伤害字段解析规则。
+runtime 内部复用下述 C++ 权威实现，不在脚本层复制生命值或移动状态。runtime 随脚本对象 GC 销毁，
+`ownership()` 返回 `owned`。
+
+同一个 runtime 还内建并注册 `standardCombatAbilities()` 的 20 个定义。`grantAbility`、
+`activateAbility`、`advanceAbilities`、`cancelAbility`、`abilityGrant` 和 `matchingAbilities` 直接投影
+`AbilityRuntime`；冷却与 Action phase 只使用调用者注入的 tick/delta，不读取墙钟。`advanceAbilities`
+推进所有活跃 execution、递减冷却并同步终态链接，脚本不应另外保存 active/cooldown 状态。
+`registerTimelineAbility` 接收 `ActionTimelineEditor.snapshotJson()` 的规范 schema，将 timeline 的 actionId、
+总时长和 physical split 映射为同一个 `ActionDefinition` 的 phase timing；同时显式设置 cooldown、
+instancing、activation group 和可选 gameplay-event trigger。注册失败不会留下部分 definition。
+`replaceTimelineAbility` 使用相同参数事务式热替换已有定义：grant、per-owner instance 与剩余冷却保持不变；
+已激活 execution 继续持有提交时的旧快照，下一次激活才读取新的 timeline 与 actionId。
+已有 grant 时不能热切换 instancing policy，避免悄悄改变 instance 身份语义。
+
+## 角色移动与导航
+
+`CombatLocomotionRuntime` 以 `SubjectRef` 注册角色，并唯一拥有水平位置、速度、朝向、移动意图和导航目标：
+
+```cpp
+DirectCombatNavigationProvider navigation;
+CombatLocomotionRuntime locomotion(navigation);
+locomotion.registerSubject({fighter, "fighter:player", {0.0, 0.0}, 5.0, 18.0});
+locomotion.setMoveIntent(fighter, {1.0, 0.0}, 1.0);
+locomotion.advance({tick, fixedDelta});
+```
+
+方向不要求预先归一化，速度比例必须位于 `[0,1]`。玩家或 AI 的直接移动会清除该角色旧导航目标；
+`navigateTo` 则要求安装 `ICombatNavigationProvider`。内置 `DirectCombatNavigationProvider` 适合无障碍 arena。
+启用 2D/3D profile 时，可选 `combat_navigation` 卫星提供 `PathfinderCombatNavigationProvider`：
+
+```cpp
+map::Pathfinder pathfinder(width, height);
+auto navigation = combat::navigation::PathfinderCombatNavigationProvider::create(
+    pathfinder, {{worldOriginX, worldOriginZ}, cellSize});
+CombatLocomotionRuntime locomotion(*navigation.value());
+```
+
+它把世界 X/Z 投影到地图格，每步调用 canonical `Pathfinder` 取得下一 waypoint；不会缓存 Path，因此地图阻挡、
+TileLayer revision 或代价改变会在下一步重新规划。不可达目标返回 `NotFound`，并由 locomotion 的整帧事务语义保证
+所有角色都不发生部分移动。`Pathfinder` 必须比 provider 活得更久。
+
+整帧更新具有原子语义：运行时先复制全部状态，再依次取得导航 steering、限制加速度并积分，全部成功后才
+发布。Provider 失败、返回非有限值或非法比例时，没有任何角色移动。Provider 是借用对象，必须比运行时活得
+更久，或者在销毁前调用 `clearNavigationProvider`；若清除时仍有活动目标，后续 `advance` 会明确失败，目标不会
+被悄悄丢弃。到达目标会返回 owning `CombatLocomotionEventKind::Arrived` 事件。
+
+## 组合边界
+
+移动状态应由表现层投射到 Scene/Physics，由 Ability Active 阶段决定冲刺、闪避等动作何时写入移动意图。
+Ability 生命周期仍由 `AbilityRuntime`/`ActionRuntime` 唯一拥有，伤害仍通过 `DamageRuntime` 或
+`CombatActionDamageSink` 提交；不要在角色 Controller 中复制冷却、动作阶段或生命值。

+### Native vegetation wind reference (C++)
+
+`VegetationWindState` holds caller-owned direction, strength, published `phase` and private-source-equivalent
+`updatePhase`. Normally callers use the checked operations rather than editing either phase directly.
+`advanceVegetationWind(state, forward, strength, dt)` follows Pcg WindManager's
+smoothed globals, downward direction component and phase advance; dt is explicit.
+The phase subtracts 100 once when greater than 100, matching the source rather than
+silently applying a different modulo rule. Invalid or overflowing results preserve state.
+
+`evaluateVegetationWind(input, state)` implements PW_GeneralWind distance attenuation,
+main/branch/leaf flex, object scale/orientation compensation and source volume normalization.
+`VegetationWindInput` includes position, world offset, camera, object transform, width/height,
+flex/frequency, maximum distance, injected sin(time/4) and sin(time), and enabled/billboard/alphaTest
+switches. The root's source 0/0 normalization resolves to zero displacement. A singular transform,
+invalid dimensions/globals or unrepresentable result returns a diagnostic. Double intermediates
+and float output define tolerance-based behavior, not GPU bit equality.
+
+These functions provide the CPU reference. The same deformation is now implemented in grass
+vertex shaders, with typed state/profile and checked Squirrel operations. No wall clock, callbacks, scene references
+or global state are retained. Caller serializes access to the single mutable state owner.
+
+`VegetationWindProfile` separates material controls from vertex inputs and defaults to disabled.
+`packVegetationWind(state, profile, seconds)` returns a validated 14-float snapshot intended for
+slots 18–31 of the grass shader: direction, strength, phase, signed distance, flex, frequency,
+sin(seconds/4) and sin(seconds). Zero distance encodes disabled wind; negative distance selects
+the source billboard branch. Disabling alphaTest zeros leaf flex without changing alpha discard.
+The calculation is pure and validates disabled profiles too. Grass shaders reserve slots 18–31:
+`windGlobals` vec4 at 18, `windPhaseDistance` vec2 at 22, `windFlex` vec3 at 24,
+`windFrequency` vec3 at 27, and `windSineTime` vec2 at 30. Defaults disable motion.
+`applyGrassWind(shader, state, profile, seconds)` checks the complete wind schema and packet
+before publishing any uniform bytes. Invalid input/schema leaves the prior shader storage intact.
+It performs no GPU allocation and retains no references. Call on the Graphics owner thread outside
+draw/capture callbacks. Re-baking resets shader defaults; reapply the caller-owned snapshot afterward.
+The terrain-stamping example uses this API with `terrainGrass.getShader()` and an explicit clock.
+
+`GrassFoliageSettings` selects the static PW/Pcg foliage surface profile. Its script fields are
+`baseR`, `baseG`, `baseB`, `alphaCutoff`, `normalStrength`, `renderDistance`, `fadeRange`,
+`hardRenderDistance`, `density`, `snowMinimumHeight`, `snowFadeDistance`, `snowProgress`,
+`snowR`, `snowG`, and `snowB`.
+The profile consumes albedo, tangent normal and packed metallic/occlusion/thickness/smoothness maps;
+the renderer applies distance alpha fade, height snow, native directional/ambient lighting and shadows.
+
+`TerrainDetailOverwriteSettings` ports Pcg's terrain detail override without merging its three controls:
+`pcgDetailDistance` starts the shader fade, `pcgFadeoutDistance` is the fade span,
+`unityDetailDistance` is the outer hard cutoff, and `unityDetailDensity` deterministically thins instances.
+`detailResolutionPerPatch` is classified with Pcg's exact 2/4/8/16/32 quality mapping and all other values
+fall back to VeryLow64. Apply it with `GrassField.setTerrainDetailOverwrite(settings)`; the checked Result
+value is the quality ordinal (VeryLow64=0 through Ultra2=5). The call requires an uploaded foliage profile,
+copies its settings, publishes all shader values atomically, and retains no references. The getters
+`getTerrainDetailHardDistance()` and `getTerrainDetailDensity()` expose the applied runtime state.
+
+The vertex path deforms the camera-facing card in world-relative coordinates, uses the effective
+instance up scale for the source width/height compensation, and converts back to object space.
+World/view positions follow deformation while the root varying remains unchanged. Both GLSL and
+WGSL contain the formula. Vulkan runtime screenshots verified time-dependent movement and exact
+restoration after disabling wind. Native Dawn/WebGPU runtime also accepted and executed the WGSL;
+fixed two- and four-second captures differ, while repeated disabled captures are byte-identical.
+Lighting/material output still differs across the backends, so this establishes deformation behavior
+rather than cross-backend pixel identity. The terrain-detail adapter also transports deterministic
+healthy/dry RGB coloring; PBR foliage and the remaining original material effects remain outside this path.
+
+
+### Squirrel wind controls
+
+`eve.VegetationWindState()` owns `strength` and `phase` fields, `setDirection(x,y,z)`,
+`getDirectionX()`, `getDirectionY()` and `getDirectionZ()`. `eve.VegetationWindProfile()` exposes
+`maximumDistance`, `enabled`, `billboard`, `alphaTest`, `setFlex(x,y,z)` and
+`setFrequency(x,y,z)`. Configuration is mutable; checked operations validate complete snapshots.
+
+`eve.advanceVegetationWind(state,x,y,z,strength,dt)` updates the state from a forward direction
+and explicit nonnegative dt, returning the standard Result table. Invalid values preserve state.
+`eve.initializeVegetationWind(state,x,y,z,strength)` implements Pcg's distinct
+`InstantWindApply` path: direction and clamped strength change immediately, and phase becomes
+`pow(strength*0.5+0.5,3)*0.1`. It preserves `updatePhase`, matching Pcg's private `m_windTime`;
+the next advance resumes that accumulator and republishes it. It does not reuse smoothing or read a hidden clock.
+`eve.applyGrassWind(shader,state,profile,seconds)` applies the snapshot without advancing it,
+returning a Result table and preserving shader storage on invalid values/schema. Squirrel uses its
+native float clock argument. Null or wrong object types fail VM argument conversion with a type
+exception before entering the operation. Caller owns state/profile; Graphics owns the grass shader.
+
+```squirrel
+local windState = eve.VegetationWindState();
+local windProfile = eve.VegetationWindProfile();
+windProfile.enabled = true;
+assert(eve.initializeVegetationWind(windState,1.0,0.0,0.2,0.5).ok);
+// dt and seconds are injected by the caller's update loop.
+assert(eve.advanceVegetationWind(windState,1.0,0.0,0.2,0.5,dt).ok);
+assert(eve.applyGrassWind(field.getShader(),windState,windProfile,seconds).ok);
+```
+
+### Tree prototype vertex wind
+
+`gfx.newTreeWindShader()` creates a backend-native Mesh3D vertex shader and reuses the engine's
+default PBR fragment stage. Vulkan consumes embedded SPIR-V; WebGPU consumes matching WGSL.
+The generic `newMeshShaderFromSpv` and `newMeshShaderFromWgsl` contract treats either empty stage
+as the corresponding default Mesh3D stage.
+
+`eve.TreeWindProfile()` owns `bendFactor` and `setDimensions(width,height)`. Dimensions are the
+unscaled source prototype crown width and height. `eve.applyTreeWind(shader,state,vegetation,tree,seconds)`
+validates the complete 16-float schema before publishing wind values and dimensions. Pcg bend
+scales all three flex channels. Invalid input or shader layout preserves all prior parameter bytes.
+
+The vertex shader keeps the prototype origin fixed and applies PW main-stem, branch and leaf motion
+in world-relative coordinates. Graphics owns the shader; state/profile objects remain caller-owned.
+No wall clock or scene link is retained. Call on the Graphics owner thread outside draw callbacks.
+
+### Pcg 水面系统控制器
+
+`eve.WaterSystemSettings()` 配置 `refreshRate`、`infiniteMode`、`autoRefresh`、
+`ignoreSceneConditions`，并通过 `setAutoUpdateMode(0|1)` 选择 Interval 或 SceneConditions。
+`eve.WaterSceneConditions()` 提供 `sunIntensity`、`hour`、`minute`、`sunAvailable`、
+`timeAvailable`，以及 `setSunColor(r,g,b)`、`setSunDirection(x,y,z)`。调用者提交快照，
+因此控制器不会搜索全局场景，也不会持有相机、太阳或玩家指针。
+
+`eve.WaterSystemState()` 暴露权威 `seaLevel`、`positionX`、`positionY`、`positionZ`、
+`refreshRemaining`、`sceneCheckFrames`、`refreshRevision` 和 `initialized` 状态。
+先调用 `initializeWaterSystem(state,settings,scene,initialFrames)`；随后每帧调用
+`advanceWaterSystem(state,settings,scene,playerX,playerZ,dt,nextFrames)`。返回的 Result 值为
+本帧是否应重新生成反射。无限模式把 X/Z 跟随输入位置并始终把 Y 锁定为 seaLevel。
+Interval 模式保留 Pcg 的严格小于零触发和 refreshRate 重置；SceneConditions 比较太阳颜色、
+强度、方向与可选时间，并使用调用者注入的 nextFrames 取代隐藏随机数。
+`updateWaterSeaLevel(state,level,regenerate)` 原子更新高度，并在要求重建时递增 refreshRevision。
+所有失败都保留原状态；dt、刷新间隔、场景值和延迟会完整验证。
+### Pcg WindManager 音量控制
+
+`eve.VegetationWindAudioState()` 与
+`eve.advanceVegetationWindAudio(state,windStrength,transitionTime,dt,enabled,clipAvailable)` 移植
+WindManager 的风声控制器。状态拥有 currentWindSpeed、anchorVolume、volume、processing 和 playing；
+函数只计算确定性的音量状态，不跨模块持有 Audio Source。脚本应创建循环、listener-relative Source，
+每帧把 state.volume 写入 Source。实现保留源码行为：currentWindSpeed 不更新，非零风速每帧重启处理；
+上升在目标下方 0.05 内吸附，下降比较不对称而通常渐近目标。dt 与 transitionTime 均显式注入。
+
+### Pcg 程序化水面网格
+
+`eve.WaterMeshSettings()` 提供 `sizeX`、`sizeY`、`sizeZ`、`densityX`、`densityY`、`height`，
+并通过 `setType(0|1)` 选择 Plane 或 Circle。`eve.calculateWaterMeshTriangles(settings)` 在分配前返回
+Pcg 算法的三角形数量；`water.createProceduralMesh(settings)` 验证并上传网格，返回顶点数量。
+Plane 按 `round(density/40*size)+1` 建立规则格点。Circle 使用同心六边环，环数取
+`round(densityX/40*sizeX/2)`，并保留 Pcg 的环缝合索引、UV 缩放与非对称 X/Z 密度行为。
+无效、过小或超过单轴 4096 点的输入返回诊断且保留 Water 当前网格。Custom 对应调用者直接提供
+EVEngine Mesh，不复制 Unity MeshFilter 的资源引用模式。
+
+### PWS 水波方向
+
+`water.setWaveDirectionAngle(degrees)` 返回标准 Result，并设置 PWS_WaterSystem 的 `directionAngle`，并将任意有限角度归一化到
+[0,360)；`water.getWaveDirectionAngle()` 返回当前角度。Vulkan GLSL 与 WebGPU WGSL 都按该角度旋转
+顶点位移和片元细浪坐标。实现把角度编码在 128 字节水参数块的 ripple-count 小数部分；整数涟漪数量保持
+不变，避免超过 Vulkan 保证支持的最小 push-constant 容量。
+
+### Pcg 水深色带
+
+`eve.WaterDepthGradient()` 分别拥有颜色键和透明度键。`addColorStop(time,r,g,b)` 与
+`addAlphaStop(time,a)` 返回 Result；`clear()` 清空两组键。`water.setDepthGradient(gradient,resolution)`
+生成 `resolution × resolution` 的 RGBA8 Clamp 色带，并严格按 Pcg 使用 `x/resolution` 采样，
+返回像素数量。可通过 `getDepthGradientTexture()` 将同一纹理设置给使用 Water shader 的
+Renderable3D normal slot；直接调用 Water.draw 时会自动绑定。`clearDepthGradient()` 恢复深浅双色模式。
+无键、重复时间或 2..4096 外的分辨率失败并保留当前纹理。
+
+### Pcg 平面水反射规划
+
+`eve.WaterPlanarReflectionSettings()` 移植 `PcgPlanarReflections.PlanarReflectionSettings`：反射开关、
+天空跳过、Full/Half/Third/Quarter 分辨率倍率、clip-plane 偏移、反射层、阴影、统一或逐层渲染距离和
+基础纹理分辨率。`setResolutionMultiplier(0..3)` 选择倍率，`setLayerDistance(layer,distance)` 设置 32 层距离。
+`eve.WaterPlanarReflectionInput()` 通过 `setCameraPosition`、`setCameraForward` 及 `waterPlaneY`、`renderScale`、
+`orthographic`、`reflectionOrPreviewCamera` 提供不可变帧快照。
+
+调用 `buildWaterPlanarReflectionPlan(output,settings,input)` 后，output 包含镜像相机位置/方向、世界裁剪平面、
+反射矩阵、排除水层 4 的 culling mask、32 层距离、捕获分辨率和 `shouldRender`。Third 精确保留 Pcg 的
+0.33 倍率及整数截断。规划器纯计算且不持有相机、纹理或场景节点；调用者用结果配置现有离屏捕获，再将纹理
+传给 `Water.drawWithPlanarReflection`。非法枚举、非有限值、负距离或无效分辨率返回 Result，保持 output 不变。
+
+设置字段为 `disableSkyboxReflections`、`clipPlaneOffset`、`reflectLayers`、`shadows`、
+`enableRenderDistance`、`enablePerLayerDistances`、`customRenderDistance` 和 `textureResolution`。
+结果字段为 `textureWidth`、`textureHeight`、`cullingMask`、`renderShadows`；读取镜像数据使用
+`getCameraX()`、`getCameraY()`、`getCameraZ()`、`getForwardY()`、`getLayerDistance(layer)` 与
+`getReflectionMatrix(column,row)`。
+
+### Pcg 水下效果状态机
+
+`UnderwaterColorGradient.addStop(time,r,g,b)` 建立深度或时段颜色渐变，`clear()` 清空键。
+`WaterUnderwaterSettings` 提供 `enabled`、`supportFog`、`supportPostFx`、`enableTransitionFx`、
+`useCaustics`、`hdrp`、`overrideFogColor`、`fogDepth`、`fogDistance`、`hdrpFogDistance`、
+`nearFogDistance`、`fogDensity`、`playbackVolume`、`causticSize`、`framesPerSecond`、
+`causticTextureCount`、`overrideFogCurve`、`anisotropyShallow`、`anisotropyDeep`，并用
+`setFogColorMultiplier`、`setOverrideFogMultiplier` 写入颜色乘数。
+
+`WaterUnderwaterInput` 的 `cameraY`、`seaLevel`、`timeOfDay`、`causticTicks`、`hasMainLight` 和
+`setMainLightColor` 是不可变帧输入。调用
+`advanceWaterUnderwaterEffects(state,output,settings,input,depthGradient,timeGradient,postExposureCurve,postColorGradient)` 后，
+`WaterUnderwaterState` 保存 `initialized`、`isUnderwater`、`causticFrame`；output 发布
+`entered`、`exited`、`playSubmergeDown`、`playSubmergeUp`、`loopAudio`、`particles`、`horizon`、
+`surfaceVfx`、`postFx`、`transitionFx`、`caustics`、`causticSize`、`depth01`、`fogStart`、
+`fogEnd`、`hdrpBaseHeight`、`hdrpMeanFreePath`、`hdrpProbeDimmer`、`hdrpAnisotropy`、
+`hdrpDepthExtent`，颜色由 `getFogR()`、`getFogG()`、`getFogB()` 读取。
+
+相机位于海面或以下视为水下。普通路径按深度渐变、主光颜色和非负分量偏移生成雾；override 路径按
+timeOfDay 渐变和乘数生成雾。HDRP 输出精确保留 Pcg 的深度插值常量。音频、粒子、Volumetric、灯光
+cookie 与后处理仍由各 provider 消费该快照；状态机不持有跨模块对象。所有输入先完整验证，失败时 state
+与 output 均保持不变。
+
+`WaterSurfaceFogSnapshot` 保存离水后恢复的 `density`、`start`、`end`、`height`、`heightFalloff`，
+颜色通过 `setColor(r,g,b)` 设置。`applyWaterUnderwaterFog(volumetric,output,surface)` 在完整验证后，把水下
+`fogColor`、`fogDensity`、`fogStart`、`fogEnd`、`fogHeight` 写入借用的 `Volumetric`；离水时恢复 surface。
+EVEngine 的距离雾要求非负起点，因此 Pcg 默认 `nearFogDistance=-4` 在 provider 边界钳制到 0。
+`Volumetric.projectDirectionalCookie(graphics,depth,cookie,worldSize,intensity)` 从硬件深度重建世界位置，
+沿主光方向建立投影平面并重复采样 cookie；参数只在本次渲染调用中借用，不跨帧保存纹理指针。
+
+`UnderwaterScalarCurve.addKey(time,value)` 与 `clear()` 定义时段曝光曲线。设置中的
+`timeDrivenPostFx`、`constantPostExposure`、`setConstantPostColor(r,g,b)` 选择 Pcg 的天气时段模式或
+固定模式。输出的 `postExposure` 和 `getPostR()`、`getPostG()`、`getPostB()` 是本帧后处理值；
+`WaterSurfacePostFxSnapshot` 用 `exposureEv` 和 `setColor(r,g,b)` 保存表面状态。
+`applyWaterUnderwaterPostFx(graphics,camera,output,surface)` 将水下曝光写入借用的 Camera3D，并把 RGB
+颜色过滤写入 Graphics 的最终 HDR 曝光阶段；离水时原子恢复 snapshot。Vulkan SPIR-V 与 WebGPU WGSL
+使用相同的线性颜色乘法。
+Pcg 内置 transition prefab 的 Y 尺寸 0.05 和 `blendDistance=0.025` 分别对应设置中的
+`transitionHalfHeight=0.025` 与 `transitionBlendDistance=0.025`。水下距海面不超过半高时
+`transitionWeight=1`，随后在 0.025 米内衰减到 0；`transitionVignette=0.25` 和
+`transitionLensDistortion=0.252` 来自原始 Post Processing asset。输出发布同名 vignette/lens 值，
+`WaterSurfacePostFxSnapshot.vignette` 与 `lensDistortion` 保存表面状态；适配器将它们接入 Vulkan/WebGPU
+最终 HDR 合成的径向暗角和 UV 畸变。该 profile 启用的 Lift/Gamma/Gain trackball 先按 Unity Post Processing v2 的
+`ColorToLift`、`ColorToInverseGamma`、`ColorToGain` 转为 HDR 系数，再按 `transitionWeight` 从
+中性值混合；`setTransitionLift`、`setTransitionInverseGamma`、`setTransitionGain` 可覆盖资源值，
+`WaterSurfacePostFxSnapshot.setLiftGammaGain(...)` 保存离水后的恢复状态。profile 的黑色 Color Filter 同样按
+过渡权重从白色混合，并与既有水下时段颜色相乘；`setTransitionColorFilter(r,g,b)` 可覆盖该资源值。
+脚本可用 `getTransitionLiftR()`、`getTransitionInverseGammaR()`、`getTransitionGainR()` 和
+`getTransitionColorFilterR()` 读取代表性的红通道结果以诊断当前混合状态。
+`transitionVignetteSmoothness=0.8`、`transitionLensScale=1.02`（surface snapshot 中对应
+`vignetteSmoothness`、`lensScale`）保留 profile 的其余启用值；混合时分别从
+Unity 的中性值 0.2 和 1.0 过渡。最终 pass 使用 Post Processing v2 的 classic vignette 幂函数以及正镜头
+畸变的 theta/sigma/tangent 采样公式，而非简单二次 UV 偏移。
+`WaterSurfaceMaterialSnapshot` 用 `setColor(r,g,b)` 和 `alpha` 保存水面 tint。
+`applyWaterUnderwaterMaterial(renderable,output,surface)` 对应 Pcg `UpdateUnderwaterMaterial`：水下把
+`getUnderwaterMaterialR()`、`getUnderwaterMaterialG()`、`getUnderwaterMaterialB()` 发布的颜色写入专用水面
+Renderable3D，离水时恢复 snapshot。有主光时颜色来自 `mainLightColor`，没有主光时使用 Pcg 的
+`#CFCFCF` 回退值；适配器同步借用对象且在验证完成前不修改 tint。
+`applyWaterUnderwaterHorizon(horizon,output)` 同步借用 Renderable3D，并严格按状态机的 `horizon` 输出控制
+可见性；HDRP 路径和离水状态都会隐藏该网格。`getVisible()` 可读取最终可见状态。
+
+`WaterUnderwaterDisableTriggerState` 与 `WaterUnderwaterTriggerEvent` 对应 Pcg
+`DisableUnderwaterFXTrigger`。事件的 `sensorTag`、`visitorTag`、`entered`、`exited` 从 `World3D` 的
+begin/end trigger 缓冲复制 Sensor/Visitor Shape Tag，
+再调用 `advanceWaterUnderwaterDisableTrigger(state,event,expectedSensorTag,expectedVisitorTag)`；匹配的 enter
+把 `effectsEnabled` 设为 false，匹配的 exit 恢复为 true，其他标签不改变状态。每个事件必须恰有一个方向，
+非法标签或方向在发布前失败。将结果写入 `WaterUnderwaterSettings.enabled` 后再推进水下状态机。
+
+Pcg 自动景深跟焦计算使用 `DepthOfFieldFocusSettings/Input/State/Output` 和
+`evaluateDepthOfFieldFocus(state, output, settings, input)`。应用层负责用 World3D 或其他权威场景查询提供
+中心射线命中距离或目标距离；计算器复现 FollowScreen、FollowTarget、FixedOffset、玩家遮挡回退到最大距离
+以及 `deltaSeconds * response` 平滑，并输出 focusDistance、aperture 和 focalLength。状态由调用者持有。
+字段 `tracking`、`interactWithPlayer`、`focusOffset` 控制模式与偏移；输入字段 `hasRayHit`、
+`hitPlayer`、`rayHitDistance`、`hasTarget`、`targetDistance` 描述查询结果。状态字段
+`maximumExceeded` 记录玩家遮挡或最大距离回退，输出字段 `active` 表示效果是否启用。
+
+`gfx.newDepthOfField()` 创建跨后端景深 compositor。`DepthOfField.apply(source, linearDepth,
+focusDistance, focusRange, maximumBlurPixels, nearPlane, farPlane)` 返回借用的内部 HDR 结果纹理；
+`applyTo` 写入调用者提供的 Canvas。`linearDepth` 使用 GBuffer `getDepthTexture()` 的归一化线性深度。
+焦距附近保持清晰，离焦程度按世界距离差增长，并以 `maximumBlurPixels` 限制采样半径。
+活动 Camera3D 可调用 `setDepthOfField(focusDistance, focusRange, maximumBlurPixels)`，把镜头状态接入
+最终场景合成；`clearDepthOfField()` 关闭效果。启用时应同时在 RenderControl 开启 G-buffer。
+
+### Pcg 反射探针距离裁剪
+
+`ReflectionProbeRegistry.setDistanceCullingEnabled(true)` 启用 Pcg 风格的硬距离资格；
+`setMaxRenderDistance(distance)` 设置正且有限的相机到探针中心距离。每次 `updateCamera(camera)` 更新
+所有探针的资格，`getLastDistanceCulledCount()` 返回被拒绝数量。距离外探针不会消耗 `tick()` 的捕获和
+过滤预算；重新进入范围会排队一次完整 recapture。距离判断使用严格的 `distance >= maximum` 淘汰，
+对应 Pcg 的 `distance < maximum` 启用规则。注册表仍负责八槽稳定选择、优先级和滞回。
+
+`getDistanceCullingEnabled()` 与 `getMaxRenderDistance()` 返回当前配置，便于运行时面板和存档系统读取。
+
+Camera3D 的物理镜头与裁剪读取接口为 setPhysicalLens、getAperture、getFocalLength、getNearClip 和 getFarClip。物理参数保存在相机权威组件中，供照片模式和后处理共同读取。
+
+### Pcg PhotoMode Water 权威配置
+
+PcgWaterPhotoModeAuthority 通过 setAuthority 管理唯一 Water 字段租约。它接收反射开关、额外距离、分辨率、LOD bias、Underwater fog color、density 与 distance 七个字段。applyToPlanarSettings 将值写入 WaterPlanarReflectionSettings；其中 lodBias 同时缩放实际 capture layer culling distance。applyToUnderwaterSettings 将颜色和雾参数写入 WaterUnderwaterSettings，水下求值会直接使用照片模式颜色。
+
+### Pcg PhotoMode Grass 权威配置
+
+`GrassField.setPhotoModeAuthority(true)` 将当前 GPU 草地场注册为照片模式 Grass 域唯一所有者；关闭或销毁字段时撤销。`m_globalGrassDensity` 控制 shader 的确定性实例密度丢弃，`m_globalGrassDistance` 与 `m_cameraCellDistance` 缩放硬裁剪、淡出和渲染距离，`m_cameraCellSubdivision` 以二次幂调整 cell 覆盖范围。`getPhotoModeDensity`、`getPhotoModeDistance`、`getPhotoModeCellDistance` 和 `getPhotoModeCellSubdivision` 返回当前倍率。重新上传 foliage 或调用 `setTerrainDetailOverwrite` 后会再次应用这些倍率。
+
+### Pcg PhotoMode Graphics 权威配置
+
+`PcgGraphicsPhotoModeAuthority` 绑定 Graphics、RenderControl 与 Camera3D 后，以显式租约接收 LOD bias、anti-aliasing、shadow distance、shadow resolution 和 shadow cascades。LOD bias 直接缩放所有 Renderable3D 网格 LOD 的选择距离；AA 枚举切换真实 FXAA、SMAA、TAA 或关闭合成；阴影距离写入 Camera3D 每层 caster 裁剪。完整分辨率和级联设置保存在同一状态中，供阴影资源配置使用。
+
+状态读取方法为 getAuthority、getReflectionEnabled、getReflectionDistance、getReflectionResolution、getReflectionLodBias、getFogDensity、getFogDistance、getFogRed、getFogGreen 和 getFogBlue。WaterPlanarReflectionSettings 也公开 lodBias。
+
+### Pcg PhotoMode 全局阴影倍率
+
+`PcgGraphicsPhotoModeAuthority` 同时接受 Lighting 域的 `m_globalShadowDistanceMultiplier`。实际 32 层 shadow caster 裁剪距离为 `m_shadowDistance * multiplier`，基础距离与倍率分别保存，任一字段变化都会重新投影。
+### GPU skin influence limit
+
+The native `Graphics::setMesh3DSkinInfluenceLimit` draw state selects the strongest 1, 2, or 4
+vertex influences for subsequent skinned mesh draws. Retained weights are
+renormalized in the forward, G-buffer, and shadow vertex paths. `Renderable3D`
+applies Pcg LOD `SkinQuality` per selected level; `Auto` resolves to the engine
+default of four influences.
+
+### Pcg ReflectionMasker
+
+`eve.WaterReflectionMasker()` 根据玩家在当前地形中的归一化 X/Z 位置控制平面反射。
+`configure(channel,min,max,enabled)` 的 channel 为 0 R、1 G、2 B、3 A、4 RGBA，阈值为闭区间；
+RGBA 模式任一通道命中即启用。`setMask(imageData)` 会复制像素，不跨帧保留图片指针，`clearMask()`
+清除遮罩。`evaluate(playerX,playerZ,terrainX,terrainZ,width,depth,reflectionSettings)` 返回 0 Unchanged、
+1 Enabled 或 2 Disabled，并在状态变化时同步 `WaterPlanarReflectionSettings.enabled`。
+`getEnabled()`、`getHeightFeaturesEnabled()`、`getSampleX()` 和 `getSampleY()` 返回最近状态与采样坐标。

+# 六边形立体地图（Hex Map）
+
+**脚本入口：** `hexmap`（`eve.HexMap`，模块槽位 `hexmap`）
+
+`hexmap` 是引擎的**可编辑 3D 六边形地图**层：持有尖顶（pointy-top）六边形格网、
+按 5×5 分块、按面（terrain / water / river / road）生成 CPU 网格并上传 GPU，同时
+提供世界坐标拾取、邻居查询与笔刷编辑。参考实现是 Catlike Coding 的
+[Hex Map](https://catlikecoding.com/unity/hex-map/) 工程；坐标、高程台地、悬崖、
+水面与河道几何均与之一致。
+
+## 布局与常量
+
+| 项 | 值 | 说明 |
+|----|----|------|
+| 朝向 | 尖顶 | XZ 平面，+X 向东，+Z 向北，Y 为上 |
+| `outerRadius` | 10 | 六边形外接圆半径 |
+| `innerRadius` | 8.66025404 | `outerRadius * √3/2` |
+| `elevationStep` | 3 | 每级高程的世界高度 |
+| `solidFactor` / `waterFactor` | 0.8 / 0.6 | 实心区与水面内缩因子 |
+| `terracesPerSlope` | 2（`terraceSteps` = 5） | 斜坡台地级数 |
+| `kChunkSizeX/Z` | 5 / 5 | 分块尺寸；地图尺寸必须是它的整数倍 |
+| 地面扰动 | XZ ±4，Y ±1.5 | `HexNoise`（种子决定，无需贴图资源） |
+
+偏移坐标到轴坐标：`axial = offset - (z/2, 0)`（`z/2` 向下取整）。世界坐标：
+`x = (axialX + 0.5·axialZ) · innerDiameter`，`z = axialZ · outerRadius · 1.5`。
+`HexCoordinates::fromWorldPosition` 是其精确逆变换（含立方体取整修正）。
+
+## C++ API 快查
+
+### `HexMetrics`（[HexMetrics.h](../../../src/modules/hexmap/HexMetrics.h)）
+
+常量与角点/边采样助手：`firstCorner` / `firstSolidCorner` / `firstWaterCorner` /
+`bridge` / `waterBridge` / `solidEdgeMiddle` / `terraceLerp` / `wallLerp`，
+以及 `elevationY` / `streamBedY` / `waterSurfaceY`。`EdgeVertices` 是边上 5 个
+采样点（v1…v5）。
+
+### `HexCoordinates`（[HexCoordinates.h](../../../src/modules/hexmap/HexCoordinates.h)）
+
+轴坐标 `(x, z)`，`y = -x - z`。`step(direction, distance)`、`distanceTo`、
+`fromOffset` / `offsetX` / `offsetZ`、`chunkColumn` / `chunkRow`、
+`toWorldPosition` / `fromWorldPosition`。
+
+### `HexMap`（[HexMap.h](../../../src/modules/hexmap/HexMap.h)）
+
+值类型格网，`reset(cellCountX, cellCountZ, seed)` 建立地图（尺寸必须是 5 的倍数）。
+
+- 拓扑：`contains` / `indexOf` / `coordinatesAt` / `tryGetNeighbor` / `edgeTypeTo`
+- 分块：`chunkIndexOf` / `chunkColumnOf` / `chunkRowOf` / `chunkCenter` /
+  `takeDirtyChunk` / `markAllChunksDirty` / `dirtyChunkCount`
+- 拾取：`pickCell(rayOrigin, rayDirection)` —— 无碰撞体，改为在候选格高程平面上
+  迭代求交并二分收敛
+- 查询：`elevation` / `waterLevel` / `terrainType` / `urbanLevel` / `farmLevel` /
+  `plantLevel` / `specialIndex` / `isUnderwater` / `hasRiver` / `hasRoad` / `isWalled`
+- 编辑：`setElevation` / `setWaterLevel` / `setTerrainType` / `setUrbanLevel` /
+  `setFarmLevel` / `setPlantLevel` / `setSpecialIndex` / `setWalled` /
+  `setOutgoingRiver` / `removeRiver` / `addRoad` / `removeRoads`
+- 笔刷：`editElevation` / `editWaterLevel` / `editTerrainType` / `editFeatureLevel`
+  （六边形圆盘，`collectBrush` 可单独枚举）
+
+跨格约束与参考工程一致：河流只能顺坡或从湖面流出；道路不能跨两级以上高程、
+不能穿过河流中段、城市/特殊地物会移除道路；特殊地物在有河时被忽略。
+
+### 网格生成（[HexMapMesh.h](../../../src/modules/hexmap/HexMapMesh.h)）
+
+`buildChunkSurfaceMesh(map, chunkIndex, surface, out)`，`surface` 取
+`HexSurface::{Terrain, Water, River, Road}`。生成物是 `HexMeshData`
+（position / normal / uv / index，三角形不共享顶点，`finalize()` 写平面法线）。
+
+分块所有权与参考工程一致：地面扇形按本块 25 格生成，**只有 NE / E / SE**
+方向的混合带、台地与悬崖归属本块，其余由邻块生成，因此块与块之间不会重复或漏缝。
+
+顶点只有两个纹理坐标，地形三层信息按
+`u = layerA + layerB·8 + layerC·64`、`v = weightB + weightC·16` 打包；这是当前
+顶点布局的**兼容桥**，不是地形数据格式。
+
+`HexSurface::Fog`（值 4）是唯一不能由 `buildChunkSurfaceMesh` 生成的流，因为它
+除了格子还需要可见性计数器，由 `buildFogMesh(map, visibility, chunkIndex, out)`
+生成：每个"当前不可见"的格子输出一根六棱柱（顶面 + 侧裙），裙脚垂到最低可编辑
+高程之下，因此迷雾边界上的悬崖立面也会被覆盖；第一纹理坐标 `u` 承载明暗
+（`0` = 曾经探索过但此刻无人看见，`1` = 从未探索）。迷雾流在可见性跨越 0/1 时
+自动把所在块标脏。
+
+另外两条流由 [HexFeatures.h](../../../src/modules/hexmap/HexFeatures.h) 生成，也不走
+`buildChunkSurfaceMesh`：`HexSurface::Wall`（值 5，`buildWallMesh`）输出城墙、墙塔
+与桥梁，`HexSurface::Feature`（值 6，`buildFeatureMesh`）输出 urban / farm / plant /
+special 地物。两者共用一条片元着色器，因为第一纹理坐标已经标明了部件种类：
+
+| `u` | 0 | 1 | 2 | 3 | 4 | 5 | 6 |
+|---|---|---|---|---|---|---|---|
+| 部件 | 城墙 | 墙塔 | 桥梁 | urban | farm | plant | special |
+
+城墙的归属规则与地形一致：只有当 `d ∈ {NE, E, SE}` 或该方向已经在网格之外时，
+才由本块生成该边的城墙——这样每条内部边恰好被一侧生成，而地图边界仍然闭合。
+道路横穿城墙边界时会开出城门（只生成两侧外段 + 两个端帽）；高程差产生楔形挡墙。
+
+### 地物与城墙（[HexFeatures.h](../../../src/modules/hexmap/HexFeatures.h)）
+
+参考工程实例化 prefab 模型；本引擎不携带资源，因此 `HexFeatures.cpp` 用程序化几何
+替代（墙＝两侧面 + 顶盖，塔/桥/建筑＝盒体，plant＝压扁八面体，special＝锥形柱）。
+`HexHashGrid` 是参考工程 `hashGrid` 表的确定性替代：由 `(gridX, gridZ, seed,
+channel)` 的整数哈希直接导出五个分量，因此不需要分配表、也没有全局状态，同一地图
+种子永远得到同一套地物布局。`featureThreshold(level, index)` 返回参考工程的
+三级阈值表 `{0,0,0.4} / {0,0.4,0.6} / {0.4,0.6,0.8}`，越界参数被钳制。
+
+拾取规则与参考工程一致：urban / farm / plant 三个集合各自用格子哈希判定是否
+命中，命中的里面哈希最小者胜出；`specialIndex` 非零时该格不生成普通地物。
+
+### 地图生成（[HexMapGenerator.h](../../../src/modules/hexmap/HexMapGenerator.h)）
+
+`generateHexMap(map, settings)` 把参考工程 `MapGenerator` 的流水线移植为纯 CPU 步骤：
+
+1. 全部格子初始化到 `elevationMinimum`；
+2. `regionCount` 个陆地区域从种子格生长（抖动、随机抬升/下沉，遵守地图与区域边界）；
+3. 海岸线侵蚀直至陆地占比接近 `landPercentage`；
+4. 顺坡开凿河流（含湖泊概率与已有的汇流判定）；
+5. 40 轮下风向水汽传输（蒸发、降水、坡面径流、下渗），得到湿度与温度；
+6. 按参考工程的生物群系表写地形类型与植被等级。
+
+可复现性只依赖 `settings.seed` 与网格本身：不使用时间、`random_device` 或可变静态
+状态。`elevationMaximum` 会被钳制到 `HexMetrics::kMaxElevation`；不合法或放不下的
+区域参数在改动地图之前就以 `InvalidArgument` 拒绝。生成后的地图**全部格子未探索**，
+因此调用方必须重新放置单位并重建全部块。
+
+### 搜索与寻路（[HexSearch.h](../../../src/modules/hexmap/HexSearch.h)）
+
+- `HexSearchContext`：可复用的搜索草稿（每格一条 `HexSearchData` + 按优先级分桶
+  的前沿队列）。用**相位**（`beginPhase()`，每次 +2）代替"清空 visited"，因此一次
+  搜索不付全图重置的代价。
+- `isValidDestination(map, c, occupied)`：`explored && explorable && !underwater &&
+  !occupied`；地形部分由 `HexCell.h` 的 `canHoldUnit()` 单点定义。
+- `moveCost(map, from, to, direction, occupied)`：悬崖与墙界不可通行；起点有路 = 1，
+  否则平地 5 / 斜坡 10，再加目标格的 urban+farm+plant 等级。返回**负数**表示阻断。
+- `findPath(map, scratch, from, to, rules, occupied) -> Result<HexPath>`：A\*（启发式
+  为六边形距离），代价按 `speed` 折算成"回合"，`HexPath::turns` 给出每个格子到达
+  时的回合数。目标不可进入时返回 `NotFound`，端点越界或 scratch 尺寸不匹配返回
+  `InvalidArgument`。
+- `collectVisibleCells(map, scratch, from, range, out)`：视线可达格（距离 + 目标格
+  `viewElevation` 与 `range + 起点 viewElevation` 比较，且不超过直接六边形距离）。
+
+### 可见性与迷雾（[HexVisibility.h](../../../src/modules/hexmap/HexVisibility.h)）
+
+`HexVisibility` 是**引用计数**而非布尔：多个观察者重叠时，只有最后一个离开才让格子
+转回不可见；某格第一次被看见时同时把地图上的 `explored` **单向闩锁**置位，此后不再
+回落。`increase` / `decrease` / `clear` / `resetVisibility`（按当前单位重算全图）。
+
+### 单位（[HexUnits.h](../../../src/modules/hexmap/HexUnits.h)）
+
+`HexUnitRegistry` 持有单位、寻路占用与视野贡献：
+
+- `addUnit` 立即授予视野；`unitIdAt` / `isOccupied` 用于寻路占用谓词
+  （`occupancyQuery()` 返回借用 `*this` 的可调用对象）。
+- 单位 id 就是注册表下标，删除会让后面的 id 前移；调用方不要跨删除缓存 id。
+- 移动沿二次贝塞尔曲线（Unity 参考工程的转角做法），`advance(map, visibility,
+  scratch, id, dt)` 既推进动画又返回**当前位姿样本**（世界坐标已含高程与扰动），
+  `dt <= 0` 表示只读不推进。**目的地自 `beginTravel` 起即被占用**，视野则跟着
+  实际走过的格子移动（`visionIndex`）。
+- `restore` 先清空再校验，被拒绝的载荷不会留下"半恢复"的注册表。
+
+### 存档（[HexSerializer.h](../../../src/modules/hexmap/HexSerializer.h)）
+
+`saveHexMap(map, units, out)` / `loadHexMap(bytes, map, units)`：小端、显式逐字节
+写出的自描述载荷（magic `EVEHEX\0\0` + 版本 + 尺寸 + 种子 + 每格 `HexValues` /
+`HexFlags` + 单位表）。版本不匹配会**拒绝**而不是猜测；载荷在触碰输出前整体校验
+（长度、magic、版本、尺寸上限 512 且为 5 的倍数、单位格在界内、单位格可站立、

+### 球面后端（[HexSphereTopology.h](../../../src/modules/hexmap/HexSphereTopology.h)、[HexSphereMap.h](../../../src/modules/hexmap/HexSphereMap.h)、[HexSphereMesh.h](../../../src/modules/hexmap/HexSphereMesh.h)、[HexSphereGenerator.h](../../../src/modules/hexmap/HexSphereGenerator.h)）
+
+前面所有小节都是**平面**地图：单元身份是 `HexCoordinates`，邻居是固定的整数方向偏移。
+球面后端复用同一套单元记录（`HexCellData` / `HexValues` / `HexFlags`）、同一套几何常量
+（`HexMetrics`）、同一个 `HexMeshData` 与同一份顶点编码，只替换这两件事——因为在闭合
+球面上它们才真正不成立：
+
+- **单元身份**是稠密的 `HexSphereCell`（`int32`），来自**二十面体（Goldberg）拓扑**：
+  二十面体按 `f = 2^subdivision` 细分后的**顶点**就是单元，于是
+  `cellCount = 10f² + 2`，其中恰好 12 个是五边形（恒为 `[0, 12)`，因为中点细分从不
+  重编号原始顶点）；`edgeCount = 30f²`，`cornerCount = 20f²`，每个角点恰好被 3 格共享。
+- **邻居关系**来自半边表。**方向不是算术**：六条边的方位逐格变化，而五边形只有五条边，
+  因此不存在处处成立的 `opposite(direction)`——所有跨边查询走
+  `directionOf(cell, other)`。方向 `d` 的边位于 `corner(d)` 与 `corner(d+1)` 之间，
+  这两个角点由该边两侧的单元**以相反顺序**共享。
+
+`HexSphereMap` 是 `HexMap` 的球面对应物：持有单元存储、`HexNoise`、**逐格**脏标记
+（球面没有分块网格，拓扑已经给每格一个全局稳定 id）、拾取、距离、刷子与全套编辑接口。
+高程是**径向**的：`surfaceRadius = sphereRadius + elevation · elevationStep`。
+`elevationStep` 默认取半径的 `0.006`，而不是平面的 `HexMetrics::kElevationStep`
+（3 世界单位）——后者在半径 100 的星球上会让 13 级高程跨越 39% 半径。`HexFlags` 的
+道路/河流 6 个 bit 槽直接由方向索引寻址，五边形上槽 5 永不置位。
+
+`buildSphereTerrainMesh` / `buildSphereWaterMesh` 沿用平面构建器的角点矩阵方案，顶点
+编码（`HexTerrainVertexCode`）完全一致，因此地形着色器的读法不变。三处平面假设被替换：
+
+1. **边数**不是 6（五边形是 5 条），没有任何循环可以写死 `kHexDirectionCount`；
+2. **边归属**：平面版靠分块网格（`direction <= SE`）保证每条共享边只发一次，球面改用
+   **较小的单元 id** 拥有该边——同一组边上的全序，同样保证恰好一次；
+3. **"垂直"是径向**：坡度台地沿**弧**走水平步、沿**半径**走垂直步。
+
+平面版的梯田带用弦 `v1 → v5` 跨越整条边，这在平面上安全**只因为**它的 5 个采样点共线；
+球面上采样点在弧上，弦会在每条带坡度或崖壁的边留下 T 型接缝，因此球面版按扇形同样的
+4 段拆分。地形顶点扰动也改为**切向**并把结果投影回原半径：切向偏移会以 `O(d²/r)` 改变
+半径，而这里扰动量是单元尺寸的可观比例。
+
+`generateSphereMap` 采样**三维**值噪声：`HexNoise` 是 XZ 平面场，用单元方向去采样会在
+两极塌缩（方向的 XZ 投影趋零）、在经度回绕处接缝。海平面由噪声自身的分位数确定，因此
+`landPercentage` 真正决定陆地占比，而不是听任噪声分布。输出是
+`(seed, 拓扑, 半径)` 的纯函数。

+
+`surface` 取 `0=Terrain, 1=Water, 2=River, 3=Road, 4=Fog, 5=Wall, 6=Feature`。
+`x, z` 是偏移坐标（列、行）——`pickCell` 的返回值同样是偏移坐标，与 `elevation` /
+`editElevation` / `cellPositionX` 等所有格子接口同一坐标系，因此拾取结果可以直接回喂
+给它们（`findPath` 与 `unitSample` 返回的格子也已经是偏移坐标）。`unitSample` 复用
+`advance(dt=0)`，因此返回的是含高程与扰动的插值位姿，不是地格中心。`generateMap` 按
+**当前网格尺寸**重新生成，会丢弃全部单位与迷雾状态，调用方必须在成功后重新放置单位
+并重建全部块。
+
+球面接口用 `cell`（稠密 id，`0 .. sphereCellCount()-1`），与平面接口的偏移坐标 `(x, z)`
+是**两套互不相通的地址空间**：不要拿平面坐标去喂球面接口，反之亦然。`sphereDirection`
+与 `sphereCornerDirection` 返回 `[x, y, z]` 单位向量。`newSphere` 只重建拓扑，
+`generateSphere` 才写入单元并重建网格；两者都会释放上一颗星球的网格，因此调用方必须在
+成功后重新绑定 renderable。`rebuildSphere` 是批量编辑后的重建入口——球面是**整张一个
+网格**（没有分块），每次重建都是全量，应当攒够一批编辑再调一次，而不是每改一格就调。
+
+## 生命周期与所有权
+
+- 模块**只持有一张活动地图**（参考工程的编辑器同样只编辑一张格子）；`newGrid`
+  会释放上一张地图生成的全部 GPU 网格。
+- 模块拥有 `HexMap` 与它创建的每个 `graphics::Mesh`；`chunkMeshAt` 返回**借用**
+  指针，`Renderable3D` 只能在模块存活且未换图期间引用它。
+- 某面在一张地图内可能从"有几何"变为"无几何"（例如最后一条道路被擦掉）：此时
+  该面的 GPU 网格**延迟释放**（保留到下次 `newGrid`），`chunkMeshAt` 返回
+  `null`，调用方据此隐藏 renderable，不会出现悬垂指针。
+- `loadMap` 走 `adoptGrid`：先释放旧网格、接管已解码的地图、重建搜索草稿与迷雾
+  计数器，再恢复单位。**调用方必须在成功后重建全部块并重新绑定 renderable**，
+  因为所有块都是脏的且没有任何 renderable 指向新网格。
+- 主/渲染线程亲和；不调用未知回调，不跨外部调用持锁。
+
+## 示例
+
+`examples/hex-terrain-3d` 是本模块的完整示例（与之无关的 `examples/hex-terrain` 是
+`mesh.hexterrain` 配方，保持原样）：`WASD` 平移、`Q/E` 旋转、滚轮缩放，
+`1`–`5` 切换高程/水面/地形/河流/道路模式，`[`/`]` 调整笔刷半径，`,`/`.` 切换地形
+调色板，左右键升降或拖拽绘制河流与道路，`R` 换种子、`F` 换地图尺寸、`N` 重建。
+第二轮补上战争迷雾、单位与寻路、存档：`tab` 切换选中单位，`g` 规划到光标格的路径，
+`space` 出发，`escape` 取消预览，`t`/`y` 增删单位，`F5`/`F9` 存档与读档。第三轮补上
+城墙/桥梁/地物与地图生成器：`m` 按当前尺寸生成一张程序化地图（重新随机种子）。
+
+存档载荷经 `eve.Filesystem().writeText()` 落到保存目录，读回时先整体校验再接管
+网格，因此损坏的文件不会破坏当前地图。
+
+`examples/hex-planet` 是**球面后端**的示例：轨道相机绕星球旋转，`LMB` 拖拽改变
+方位角/仰角，滚轮缩放，`space` 自动旋转，`R` 换种子，`[`/`]` 切换细分级别，`-`/`=`
+调整陆地占比，`F5` 抓帧。默认姿态是静止的，所以两次运行抓到的画面几乎逐像素
+一致（仅 ImGui 覆盖层有像素级差异）。它自带两个片元着色器：平面地形着色器把
+`vWorldPos.y` 当海拔、`N.y` 当"上"、细节噪声投影到 XZ、远处用距离雾——这四件事在球面上
+都不成立，因此球面版保留调色板与 BRDF、只替换这四处。另外宿主会在片元输出之后再套一层
+Reinhard 风格的 tonemap（调试着色器输出常量 `1.0` 到达帧缓冲是 `224/255`，即
+`y = x/(x+0.139)`），两个球面着色器都用 `hostTonemapInverse` 反解这条曲线，否则颜色会被
+压缩两次且无法调参。
+
+相机方面示例做了一个必要的修正：`eve.Camera3D()` 的默认裁剪范围是 `0.1..100`，
+比一张地图的跨度还小，超过 100 世界单位的地形会被静默裁掉，远端的缩放档位因此只
+能看到空屏。示例现在每帧按地图跨度推导远裁剪面，并让最远缩放距离随之放大
+（`ZOOM_FAR_MARGIN`），所以任何地图尺寸都能完整入画。
+
+## 已知边界（尚未实现）
+
+瀑布与河口（estuary）几何尚未移植；河道是等宽中心线带，未做 7 分支交汇解算；迷雾按
+"已探索 / 当前可见"两态渲染（不区分"当前可见"之外的中间态透明度），且迷雾柱顶取
+自身与邻居的最高面，因此在高差极大的边界上会比参考工程略"鼓"；地物是程序化几何
+而非参考工程的 prefab 比例。
+
+水面与参考工程逐方向对齐：邻居是水就发一个中心三角形 + 桥接四边形（桥接只由
+NE/E/SE 侧发，避免水/水边界重复），邻居是陆地就发四个细分楔形三角形 + 四段岸带；
+岸带**平铺在水面高度**，只借用邻格的实体角点平面位置，不借用它的高程——倾斜到岸顶的
+写法会在每条六边形边上留下一条亮带。`HexSurface::Water` 因此完全水平，测试
+`hexmap.mesh.waterSurfaceIsFlatAtAShore` 会断言所有水面顶点同高、所有法线朝 +Y。
+
+地图生成器的两处刻意偏离参考工程（均已在源码中注释）：侵蚀取共享搜索前沿中最低的
+格子，而参考工程是均匀随机挑选可侵蚀格；温度抖动使用私有的值噪声，而参考工程采样
+噪声贴图。生成器的 `HemisphereMode` 只实现参考工程的 `North` 映射。
+
+球面后端的已知边界：球面**没有**河流、道路、城墙、地物、迷雾与单位的网格与查询接口
+（`HexFlags` 的位可以设置，但没有对应的球面几何与寻路）；海洋是每格一个六边形盖面，
+没有浅滩、折射与岸线浪花，且按模块自身的规则 `waterLevel == elevation` 不算淹没，
+所以海平面上的格子会露出；崖壁是径向直墙，没有悬垂或侵蚀细节；球面生成器没有河流、
+侵蚀与板块构造——平面的 `HexMapGenerator` 没有移植过来。球面地图也**没有存档格式**。

+选择 `source` 或 `1-source`，执行运算，再按 `[0,1]` 内的 `strength`
+从原值插值；中间值不钳制，所以连续调用的顺序有意义。
+
+`TerrainStampSettings()` 是脚本持有的参数对象：
+
+- `setGrid(originX, originZ, spacingX, spacingZ)` 设置接收高度图的世界原点与采样间距。
+- `setCenter(x, z)`、`setSize(width, depth)`、`setRotation(radians)` 设置印章位置和旋转。
+- `amplitude`、`baseHeight`、`blendStrength` 为可写浮点字段，默认值分别为 1、0、0.5。
+
+脚本浮点参数使用 `1.0` 这样的浮点字面量；当前 VM 为单精度。C++ 世界坐标
+配置保留 double，脚本不能提供超出 VM 数值精度的坐标。
+
+`ProcgenHeightmap.applyStamp(stamp, settings, operation, localMask, globalMask)`
+返回标准 Result，`value` 为变化的采样数。`operation` 为 0 Raise、1 Lower、
+2 Blend、3 Set、4 Add、5 Subtract。Raise/Lower 取高度包络；Blend 使用
+`blendStrength`；Add/Subtract 对已有高度加减印章高度。
+
+印章和两个蒙版使用同一旋转矩形内的 UV，分别双线性采样，分辨率可不同。
+局部蒙版作用于 `stamp * localMask`，再乘 `amplitude`、加 `baseHeight`；
+全局蒙版钳制到 `[0,1]` 后控制最终高度变化。值为 1 的单像素蒙版表示无过滤。
+旋转矩形外不变；地形 `(x,y)` 的世界位置为
+`(originX+x*spacingX, originZ+y*spacingZ)`，相邻瓦片可共享边界坐标。
+
+```squirrel

+调用同步执行，不保留传入对象。调用者必须独占目标高度图；同一对象作为输入
+与输出也按修改前数据计算。输入尺寸、有限值、枚举与参数先检查，结果溢出也
+拒绝整个操作，不留下部分写入。内存分配失败按 C++ 分配异常处理。
+该接口使用原生地形高度单位，不模拟 Unity packed height、自适应基底或

+
+### 蒙版生成与曲线纹理
+
+以下都是 `ProcgenHeightmap` 方法，修改接收者并返回标准 Result（`value` 为变化
+的采样数）。运算先构建候选结果，再统一发布；源、曲线和目标允许别名。
+所有输入必须有限，曲线必须是非空的一行高度图。
+
+- `transformMask(source, curve)`：以源标量为 UV，通过 Clamp/Bilinear 曲线纹理变换。
+- `rangeMask(source, minimum, maximum, filterCurve, strengthCurve)`：先计算
+  `smoothstep(minimum, maximum, source)`，再依次采样过滤曲线和强度曲线。
+  `minimum < maximum`；用世界高度范围即可生成高度适应度。
+- `deriveSlope(heights, spacingX, spacingZ, heightScale)`：从按世界间距缩放的高度
+  导数生成 `1-normal.y`，**不是坡度角度**。输出可继续传入 `rangeMask`。
+  内部用中心差分，边缘单边差分；单采样轴的导数为零。分块处理时应提供
+  邻接 halo 再裁切，不能把没有邻块的边缘差分当成跨瓦片连续性保证。
+- `distanceMask(settings, axis, filterCurve, strengthCurve)`：距离过滤后再应用
+  强度曲线。`axis` 为 0 圆、1 X、2 Z、3 圆角方形。
+
+`TerrainDistanceMaskSettings()` 提供浮点字段 `offsetX`、`offsetZ`、`scaleX`、
+`scaleZ`、`rotation`（弧度）、`roundness`，以及布尔字段 `tiling`。
+默认偏移和旋转为零，缩放为 1，圆角指数为 0.5，不重复。缩放非零、圆角指数
+严格为正。圆角方形范围外的过滤值为零，仍需经过强度曲线，因而不一定输出黑色。
+
+曲线按 GPU 纹理坐标采样：第 i 个 texel 中心在 `(i+0.5)/width`。因此两像素
+曲线 `[0,1]` 在 UV=0.25 处为 0、0.5 处为 0.5、0.75 处为 1，不能视作
+两个端点之间的普通线性函数。可以提供原包导出的 256×1 曲线数据；目前没有
+实现 Unity AnimationCurve 资产解析。距离蒙版的输出 UV 也取像素中心。

+
+### Terrain contrast
+
+`ProcgenHeightmap.applyContrast(mask, strength, featureSize)` returns a structured Result with the changed sample count. C++ exposes `applyTerrainContrast` in `TerrainEffect.h`. The mask must match the destination dimensions and contain values in [0,1]; strength is finite and nonnegative (values above 1 extrapolate; Pcg defaults to 2), and featureSize is a nonnegative texel offset. Fractional offsets use clamped bilinear sampling. The nine-tap average weights the center and axial samples by 1 and diagonal samples by 0.75 (total weight 8). The output is `height + 0.5 * (height - average) * strength * mask`.
+
+The operation reads an immutable snapshot, including when the mask aliases the destination, and publishes atomically. Invalid inputs and float overflow leave the destination unchanged. Heights remain in native caller units without Unity packing or saturation. Filtering across tiles requires a supplied neighbor halo and cropping. Execution is synchronous with exclusive destination access and no retained references, callbacks, RNG or time dependency.
+
+### 地形效果（CPU）
+
+`TerrainEffect.h` 中的原生操作均同步执行，借用输入，不保留指针、回调或外部状态。
+目标必须由调用者独占；先计算完整候选再发布，失败不留下部分高度修改。
+Squirrel 接口返回标准 Result，`value` 为最终变化的采样数。蒙版与目标尺寸相同，
+混合权重在 `[0,1]`；重复效果中的蒙版始终使用调用开始时的数据，允许输入别名。
+这批操作没有新 ECS、持久数据格式、可选服务、时钟或 RNG。
+
+- `applySmooth(mask, settings)`，参数对象 `eve.TerrainSmoothSettings()`：
+  `radius=10`（非负 texel 间距）、`verticality=0`（`[-1,1]`）、`strength=1`。
+  先水平后垂直，每遍为中心加七对加权采样。`verticality=-1` 只降低、`1` 只抬高。
+  保留原 Shader 两遍都使用 X 方向 texel 大小的行为：非方形栅格的垂直采样间距
+  为 `radius*height/width`。Clamp/Bilinear 边缘寻址；提供 halo 后裁切时须保持
+  该采样比例，不能假定不同宽高比的独立块自动无缝。
+- `applyRidges(mask, settings)`，参数对象 `eve.TerrainRidgeSettings()`：
+  `mixStrength=0.5`、`exponent=16`、`strength=1`、`minimum=0`、`maximum=0.5`、
+  `passes=18`。每遍先做水平区间幂变换，再将更新后的值用于垂直区间幂变换，
+  与四邻域均值混合，最后按蒙版插值并裁剪。`passes` 是实际应用次数，
+  Pcg 编辑器迭代参数 N 对应 `floor(N)+2` 次；0 次保持不变。
+  裁剪在蒙版插值之后，蒙版为零也会裁剪超出 bounds 的值。
+  世界高度调用者须设置 `minimum/maximum`；默认值对应原 Shader 的标量域。
+- `applyTerrace(mask, settings)`，参数对象 `eve.TerrainTerraceSettings()`：
+  `count=100`、`bevel=0`、`strength=1`。count 是高度单位的倒数，必须为正。
+  高度乘 count 后按最近偶数舍入；只有正方向余量严格大于 `1-bevel` 时保留
+  原高度，随后插值。没有加入原源码中已注释掉的 jitter 或未使用的外侧 bevel。
+  半整数舍入遵循 [HLSL round 文档](https://learn.microsoft.com/en-us/windows/win32/direct3dhlsl/dx-graphics-hlsl-round)。
+- `applyPower(mask, power)`：指数是 `4-power`，不是 power 本身。
+  不自动归一化输入；遮罩内负高度，以及指数非正时的零高度，返回失败以避免
+  未定义幂运算。零权重样本不求幂。超出有限 float 范围也拒绝整个操作。
+- `applyHeightCurve(mask, curve, minimum, maximum)`：曲线为非空一行 LUT，
+  使用 `smoothstep(minimum,maximum,height)` 和 Clamp/Bilinear texel-center 采样。
+  曲线值乘 `maximum-minimum` 后与原高度按蒙版插值；保留原公式不加回 minimum
+  的行为。minimum 必须小于 maximum。
+- `applyHeightMix(local, global, settings)`，参数对象 `eve.TerrainHeightMixSettings()`：
+  `minimum=0`、`maximum=1`、`midpoint=0.5`、`strength=0.5`、
+  `clipMinimum=0`、`clipMaximum=0.5`。增量为
+  `(local-midpoint)*(maximum-minimum)*strength*global`，加到原高度后裁剪。
+  local 为有限标量，可超出 `[0,1]`；global 和 midpoint 为单位范围，strength
+  可大于 1（原编辑器允许到 2）。允许 minimum 等于 maximum，表示零高度跨度。
+  global 为零仍执行最终裁剪。
+
+```squirrel
+local target = procgen.newHeightmap(33, 33).value;
+local mask = procgen.newHeightmap(33, 33).value;
+for (local y=0; y<33; ++y) for (local x=0; x<33; ++x) {
+    target.setHeight(x, y, x == 16 && y == 16 ? 0.5 : 0.0);
+    mask.setHeight(x, y, 1.0);
+}
+local smooth = eve.TerrainSmoothSettings();
+smooth.radius = 1.0;
+assert(target.applySmooth(mask, smooth).ok);
+local terrace = eve.TerrainTerraceSettings();
+terrace.count = 100.0;
+assert(target.applyTerrace(mask, terrace).ok);
+```
+
+所有算子保留调用者传入的标量域，不自动模拟 Unity 的高度纹理打包。非线性
+效果若要与原参数对应，调用方必须提供对应的高度标量域和裁剪范围。这里处理
+已光栅化的整个操作区域；旋转笔刷、范围外保留及多瓦片的上下文仍由上层提供。
+CPU 使用固定采样顺序和 double 中间值，float 存储；跨平台/CPU-GPU 比较需使用
+数值容限，不承诺位级一致。这些接口尚不能作为原版 GPU 或可视化验收的证据。
+
+### 八邻域热侵蚀
+
+`ProcgenHeightmap.applyThermal(sediment, settings)` 对接收高度图和指定泥沙累计图
+同时计算，再统一发布；返回标准 Result，`value` 是任一输出发生变化的网格数。
+C++ 入口为 `TerrainErosion.h` 中的 `applyTerrainThermal`。两个目标必须是尺寸
+相同的不同对象，由调用者独占；高度为非负有限值，泥沙允许有限的负值。
+输入或中间结果无效、浮点溢出、内存分配失败，都不发布任何一个输出。
+
+`eve.TerrainThermalSettings()` 字段：`spacingX=1`、`spacingZ=1`、`heightScale=1`、
+`reposeSlope=11.430052`、`dt=0.00025`、`iterations=3`。间距和高度比例严格为正；
+坡度阈值、dt、迭代数非负。reposeSlope 是休止角的正切，不是角度值。
+例如默认值约为 tan(85°)。dt 是调用者注入的热侵蚀子步时长；对齐 Pcg 的
+组合模拟时，它等于 thermalTimeDelta * hydroTimeDelta。没有隐式时钟或 RNG。
+
+每个子步读取旧高度快照，用 Clamp 邻域的四个正向样本和四个对角样本求坡度。
+仅绝对坡度严格大于 reposeSlope 的高度差参与求和；对角权重为 0.707，正向
+权重为 1。差值先乘 heightScale。移动量为 `clamp(dt*sum/16,-height/2,height/2)`，
+从高度扣除并加到泥沙图中。泥沙正值表示移除，负值表示加回，不能将它直接
+解释为非负悬浮泥沙浓度。零高度格子的移动上限也为零，这是原公式的行为。
+
+本接口保留原 Thermal.compute 的标量语义，不替换现有 TerrainPipeline 的
+保守 talus 重分配。高度与泥沙之和在每格保持平衡（受 float 舍入影响），不
+承诺仅高度图的总质量守恒。重复调用可传回这两张输出继续迭代。无保留引用、
+回调或跨帧可变状态；同步调用期间不能并发观察或修改任一目标。仍不代表完整
+水力/热侵蚀联合管线或 Unity GPU 对照已经通过。
+
+### 水流状态与分阶段计算
+
+`eve.TerrainWaterField()` 创建一个独占拥有水深、速度和四向通量的空状态。
+`reset(width, height, depth)` 返回 Result，成功后重置网格及均匀水深，并清空速度
+和通量；尺寸乘积必须不超过 int 上限。`getWidth()` / `getHeight()` 返回尺寸。
+`advance(terrain, settings)` 推进一步，成功返回任意字段发生变化的网格数。
+它只借用地形，既不修改也不保留地形引用，暂不进行泥沙溶解或沉积。
+
+`sample(x,z)` 返回 Result，成功 value 是独立的值记录，包含 `depth`、`velocityX`、
+`velocityZ`、`fluxRight`、`fluxLeft`、`fluxBottom`、`fluxTop`，不是内部缓冲区引用。
+越界或空状态查询明确失败。C++ 类型为 TerrainWaterField，内部使用 Pimpl；
+禁止复制，可移动，移出后的对象为空且可 reset。脚本持有状态直到释放对象，
+无需外部注册或跨域 Link。reset/advance 要求独占访问；空闲时才允许只读查询。
+
+`eve.TerrainWaterSettings()` 提供以下有限浮点参数：
+
+- `spacingX=1`、`spacingZ=1`、`heightScale=1`、`waterScale=1`，必须为正。
+- `dt=0.05`，非负，0 表示不改变状态；没有隐式时钟或 RNG。
+- `precipitation=0.000004`、`evaporation=0.000004`，非负。
+- `flowAcceleration=-0.00049`，有符号值，对应原调用方的 flowRate*gravity。
+
+参数是 Shader 接收到的值，不隐式重复 UI 转换。Pcg 调用方对 UI 雨量/蒸发
+乘 1e-5，对 flowRate 乘 1e-4 再乘 gravity，对 simulationScale 乘 0.001
+再与 terrain texel spacing 相乘。保留原公式的流量符号和 clamped 邻域。
+
+计算明确分为完整通量场、速度与水深更新两个阶段，避免源 GPU 核同次 dispatch
+内读取尚未完成的邻格通量。平均水深严格为零时速度定义为零。保留原源码最后
+以旧水深加降雨减蒸发覆盖输运水深的行为，因此它不是保守浅水模拟器。
+内部 double 中间计算、float 存储，固定阶段顺序；不承诺与原版存在竞争读写的
+GPU 核位级等价。任意输入错误或溢出均不提交已算出的局部通量/速度/水深。
+
+```squirrel
+local flow = eve.TerrainWaterField();
+assert(flow.reset(terrain.getWidth(), terrain.getHeight(), 0.0).ok);
+local water = eve.TerrainWaterSettings();
+water.precipitation = 0.000008;
+assert(flow.advance(terrain, water).ok);
+local sample = flow.sample(0, 0);
+assert(sample.ok);
+print(sample.value.depth + "\n");
+```
+
+水力侵蚀仍需接入泥沙、热侵蚀调度与诊断层；不能以此水流阶段宣称完整水力模拟
+已经移植，或替代渲染水面的波浪/反射/折射功能。
+
+`eve.generateTerrainWaterFlowMap(target,source,settings)` 对应 Pcg 独立的旧版
+`WaterFlowMap.CreateWaterFlowMap`，不复用上述水流状态。`TerrainWaterFlowMapSettings` 字段为
+`dropletVolume`、`absorptionRate`、`smoothIterations`。它从每个非边缘 texel 投放水滴，按 X-major、
+Z-minor 顺序查找八邻域中严格更低的第一个点；没有低点时只抬高私有地形副本。每一步总是沉积完整
+absorptionRate，因此最后一步可以超过初始体积。完成后按原 `HeightMap.Flip` 交换 X/Z 轴，再执行
+顺序相关的原地四邻域平滑并钳制到 [0,1]。矩形输入要求目标尺寸为 source height × source width。
+输入无效、数值不再前进或溢出时目标保持不变；API 无随机数、隐式时间或保留引用。
+
+`eve.generateTerrainVelocityFlowMap(target,source,iterations)` 对应同一 Pcg `HeightMap` 类型的另一项
+`FlowMap` 运算。它从每格 `0.0001` 水量开始，以源码固定 `TIME=0.2` 累积左、右、下、上四向通量，
+限制单步总流出不超过当前水量，更新邻格流入后从最终通量计算二维速度幅值，并按整图 min/max 归一化；
+范围小于 `1e-12` 时输出全零。目标必须同尺寸，可以与 source 为同一对象；负迭代或任何非有限中间值
+返回失败并保留目标。该 API 与 WaterFlowMap 水滴追踪及 `TerrainWaterField` 水力状态均为独立合同。
+
+### 去除高度图台阶
+
+`eve.analyzeTerrainTerraces(classes,source,settings)` 与
+`eve.removeTerrainTerraces(target,source,classes,settings)` 移植 Pcg 4.2.2
+`HeightmapTerraceRemover` 的两阶段工具。分类值为 0=Black、1=Red、2=Green、3=Blue，优先级与源码一致：
+terrace、flat、mountain、slope terrace、black。边缘保持 Black。
+
+`TerrainTerraceRemovalSettings` 暴露 `perlinScale`、`perlinStrength`、
+`slopeTerraceThreshold`、`flatThreshold`、`verticalGradientThreshold`、
+`minimumTerraceThreshold`、`maximumTerraceThreshold`、`excludeRed`、`excludeBlack`、
+`terrainWorkflow` 和 `noiseSeed`。处理顺序固定为：选中区域 3×3 平均、梯度衰减 Perlin 噪声、
+`1/2/1` 三向滤波、sigma=1 的 5×5 高斯模糊。`terrainWorkflow=true` 保留源码
+`0.00042/0.0035` 的噪声强度比例。EVEngine 使用具名 seed 的原生 Perlin 实现，保持确定性；Unity
+`Mathf.PerlinNoise` 的私有排列不作为跨引擎逐像素合同。
+
+两个调用都先完成验证与候选计算再发布。apply 允许 target 与 source 相同，但分类图必须是独立对象；
+失败不会留下部分平滑结果，也不保留任何输入引用。
+
+### HeightMap 曲率与坡向派生图
+
+`eve.generateTerrainHeightmapCurvature(target,source,mode)` 精确对应 Pcg `HeightMap.CurvatureMap`，mode
+沿原枚举为 0=Average、1=Horizontal、2=Vertical。它以归一化像素间距计算 dx/dy、dxx/dyy、dxy，按
+Pcg 水平/垂直曲率公式限制到 ±10000，再映射至 [0,1]。平坦或退化分母按源码得到中值 0.5。
+
+`eve.generateTerrainHeightmapAspect(target,source,mode)` 对应 `HeightMap.Aspect`，mode 为 0=Aspect、
+1=Northerness、2=Easterness。完整坡向除以 360；北向性和东向性分别用 cosine/sine 映射到 [0,1]。
+实现保留源码自定义 Sign 和边缘 clamp 规则，包括平坦样本的 0.5 full-aspect 结果。
+
+两项都要求至少 2×2 的有限同尺寸栅格，允许 target/source 别名，先读取完整旧快照并在成功后原子发布；
+非法枚举、尺寸或数值失败不会修改目标。它们是 `HeightMap.cs` CPU 派生图，不等同于 shader 风格的
+`generateCurvatureMask` 径向模糊操作。
+
+### HeightMap 邻域修复
+
+`eve.filterTerrainHeightmapNeighborhood(target,source,radius,mode)` 对应 Pcg `HeightMap.DeNoise`、
+`GrowEdges` 与 `ShrinkEdges`，mode 为 0、1、2。DeNoise 只处理拥有完整邻域的内部像素，把离群值限制到
+邻居最小值与最大值之间；GrowEdges/ShrinkEdges 在边界跳过越界邻居，并把像素向邻域极值移动一半。
+
+实现刻意保留 Pcg 的 X 优先、Y 次优先原地遍历语义：同一调用中靠后的像素会读取已经更新的靠前像素。
+target 可以与 source 相同；实现先复制输入快照，在全部验证成功后发布，因此非法半径、枚举、尺寸或非有限值
+不会留下部分结果。DeNoise 要求 radius 至少为 1。
+
+`eve.smoothTerrainHeightmap(target,source,iterations)` 对应四邻域 `HeightMap.Smooth`，保留边缘 clamp、
+[0,1] clamp 和每次写回立即影响后续 X→Y 样本的行为。`eve.smoothTerrainHeightmapRadius(target,source,radius)`
+对应缩放滑窗版本，像源码一样把 radius 至少提升到 5，并保留每列第一个完整窗口只计算而不写回的行为。
+`eve.convolveTerrainHeightmap(target,source,kernel)` 对应原地卷积；只有完整覆盖 kernel 的像素会改变，结果
+限制到 [0,1]，近零 divisor 使用 1。为避免 Unity 方法对畸形数组的越界行为，原生 API 明确要求有限、
+奇数边长的正方形 kernel。
+
+`eve.generateTerrainHeightmapSlope(target,source)` 精确对应 `HeightMap.SlopeMap`：使用归一化像素间距、
+边缘重复采样、源码固定 0.5 高度比例和 `g/sqrt(1+g²)` 映射。它与旧 `GetSlopeMap` 的前向差分不同；
+后者在最后一行/列直接访问越界，因此没有作为安全公共 API 暴露。
+
+`eve.quantizeTerrainHeightmap(target,source,divisor)` 对应标量 `HeightMap.Quantize(float)`，使用 Unity
+`Mathf.Round` 的 midpoint-to-even 规则。除数必须有限且非零；别名安全，失败不修改 target。
+
+### HeightMap 栅格代数
+
+`eve.applyTerrainHeightmapScalarArithmetic(target,source,operand,operation,clampResult,min,max)` 和
+`eve.applyTerrainHeightmapRasterArithmetic(target,source,operand,operation,clampResult,min,max)` 覆盖 Pcg
+的 Add、Subtract、Multiply、Divide 及全部 Clamped 重载；operation 依次为 0–3。栅格尺寸不同时，右操作数
+按 Pcg 的 `x/targetWidth`、`y/targetHeight` 坐标和源尺寸双线性采样。原生合同拒绝除零和非有限结果，
+避免把 C# Infinity 写入后续地形管线；错误时 target 保持不变。
+
+`eve.lerpTerrainHeightmap(target,source,values,mask)` 对应 `HeightMap.Lerp`，values 和 mask 可各自采用不同
+尺寸并按相同规则重采样；插值量按 `Mathf.Lerp` 限制到 [0,1]。三项均允许 target 与任一输入别名。
+
+`eve.transformTerrainHeightmap(target,source,transform,parameter)` 覆盖基础 `HeightMap.Invert`、
+`Normalise`、`Power`、`Contrast`，transform 为 0–3。Normalise 对常量图保持原值；Power 的 parameter 是
+源码直接指数，不是 terrain effect 中的 `4-power`；Contrast 使用 `(h-0.5)*parameter+0.5` 且不隐式 clamp。
+
+`eve.copyTerrainHeightmap(target,source,mode)` 对应 `HeightMap.Copy`，mode 为 0=AlwaysCopy、
+1=CopyIfLessThan、2=CopyIfGreaterThan；条件比较以 target 调用前的当前值为基准。异尺寸 source 使用 Pcg
+归一化坐标重采样。`eve.copyTerrainHeightmapClamped(target,source,min,max)` 对应 CopyClamped，先采样再限制。
+两项都以 target 尺寸为输出权威，允许 source/target 别名，非法枚举或区间失败时不修改 target。
+
+`eve.flipTerrainHeightmap(target,source)` 对应 Pcg `HeightMap.Flip` 的矩阵转置，会把 W×H 输出调整为
+H×W；它不是水平或垂直镜像。实现先复制 source 并构造完整候选，因而支持原地调用。
+
+`eve.measureTerrainHeightmap(source,measure)` 统一提供当前样本的 Minimum、Maximum、Sum、Average、
+BaseLevel（measure 0–4）。Sum/Average 保留 Pcg X→Z 顺序的 float 累加；BaseLevel 从 0 开始扫描四条边，
+因此全负边界仍返回 0。每次调用直接读取权威样本，不要求调用者维护 Unity 的 dirty 统计缓存。
+
+`eve.quantizeTerrainHeightmapTerraces(target,source,startHeights,curves)` 对应 Pcg
+`Quantize(float[],AnimationCurve[])`。startHeights 是 N×1 严格递增栅格；curves 是 W×N 栅格，每行以
+线性采样表示一条 Unity 曲线。区间仍从最高 terrace 向下搜索，因此公共边界归入较高层。输入高度必须由
+首个 start 到 1 完整覆盖；这把 Unity 的负索引异常转成原子 InvalidArgument。
+
+`eve.measureTerrainHeightmapSlope(source,x,y,mode)` 暴露 Pcg 三个同名但不同单位的点查询：mode 0 是
+整数格点向 +X/+Z 的梯度长度；mode 1 是归一化坐标、0.9 texel 中心差并乘 10000 后限制到 [0,90]；
+mode 2 是归一化坐标四向绝对高差平均再乘 400。整数模式要求右/下邻居存在，归一化模式要求坐标在 [0,1]。
+
+`eve.fillTerrainHeightmap(target,value)` 对应 `SetHeight` 并将统一高度限制到 [0,1]；
+`setTerrainHeightmapSafe` 把越界整数坐标限制到最近边界后写入。`setTerrainHeightmapRow` 的 row 固定 X、
+需要 target-height 长度的一维 strip；`setTerrainHeightmapColumn` 固定 Z、需要 target-width strip，与 Pcg
+命名和数组方向一致。`resetTerrainHeightmap` 把对象清为 0×0。所有非 reset 写入均先验证并原子发布。
+
+`eve.sampleTerrainHeightmapSafe(source,x,z)` 将整数坐标限制到最近边界，对应 `GetSafeHeight`。
+`sampleTerrainHeightmapNormalized(source,x,z)` 接受 [0,1] 坐标并严格采用 Pcg 的 `x*width,z*depth`
+双线性规则；这与 EVEngine `sampleBilinear` 的像素坐标合同不同。`heightmap.hasData()` 验证正尺寸及完整
+样本存储，`heightmap.isPowerOfTwo()` 要求两个维度均为正二次幂。
+
+Pcg 的 MinVal/MaxVal/SumVal、UpdateStats 和 dirty 标志是同一 Unity 编辑器缓存协议。EVEngine 的
+measure API 每次读取权威样本，因此不会暴露可能过期的统计缓存或手工 dirty 开关。元数据由带
+schema/version 的 TerrainAsset、TerrainFile 或上层资产定义拥有，不附着无结构字节到通用 Heightmap。
+
+
+### 泥沙与联合侵蚀
+
+`heightmap.applyLegacyDistributedErosion(settings)` 对应 `HeightMap.Erode`：只扫描内部格点，若最大
+四向下降量位于阈值区间，就从中心移走其一半，并按所有正下降量的比例同步分配到四邻域。
+`TerrainLegacyDistributedErosionSettings` 提供 minimumThreshold、maximumThreshold 和 iterations。
+
+`heightmap.applyLegacySteepestErosion(hardness, settings)` 对应活跃的 `HeightMap.ErodeThermal`：按 X 外层、
+Z 内层原地扫描，严格依次比较下、左、右、上邻居，将最大下降量的一半乘 `(1-hardness)` 后移给首个
+最陡邻居。hardness 可使用不同尺寸，并按 Pcg 的归一化宽深双线性规则采样。
+`TerrainLegacySteepestErosionSettings` 提供 iterations、talusMinimum 和 talusMaximum。
+两个调用都原子发布、使用显式迭代数，且不依赖隐式时钟或随机数。
+
+`eve.TerrainLegacyHydraulicSettings()` 与
+`heightmap.applyLegacyHydraulic(sediment, hardness, rain, settings)` 对应旧版
+`HeightMap.ErodeHydraulic`。设置包含 `iterations`、正整数 `rainFrequency` 与 [0,1]
+`sedimentDissolveRate`。每隔 rainFrequency 轮加入 rain；四向通量保留跨轮状态并使用固定 TIME=0.2；
+更新水深后，按八邻域严格下降量与 `(1-hardness)` 搬运泥沙，地形限制到 [0,1]，泥沙保留有符号值。
+该调用先快照输入并私下完成所有迭代，成功才同时发布地形与泥沙；无隐式时钟或随机数。
+它与下面的 GPU 来源 Water→Sediment→Thermal 管线及 `WaterFlowMap` 水滴累积图是三套独立合同。
+
+`eve.TerrainSedimentSettings()` 提供 `effect=-1`、`depositRate=0.00004`、
+`bankDeposit=1`、`bedDeposit=5`。这些是实际计算系数，不是 Pcg UI 的缩放前数值。
+
+- `heightmap.applySediment(sediment, velocityX, velocityZ, waterSettings, sedimentSettings)`
+  返回结构化 Result，成功值为两个输出中发生变化的格子数。
+- `waterField.advanceHydraulic(heights, sediment, waterSettings, sedimentSettings, thermalSettings, iterations)`
+  顺序执行水流、泥沙、热侵蚀，并返回三个所有者中发生变化的格子数。
+  任一轮失败均保留调用前的地形、泥沙和水流状态。
+
+所有栅格必须同尺寸且有限，地形非负；地形与泥沙必须是不同对象。
+调用同步执行、无回调，调用方负责线程串行访问；不保留传入对象的引用。
+独立泥沙操作允许速度栅格与输出别名，始终读取调用前快照。
+`waterSettings.dt` 控制沉积和回溯；热侵蚀使用独立的 `thermalSettings.dt`，
+若匹配 Pcg 调度，应由调用方先乘水流时间步。
+
+该泥沙算子保留参考源码的特殊权重、混合坐标索引与叠加行为，
+不是标准双线性输运：无速度且无沉积时非负泥沙每轮翻倍，即使 dt 为零。
+源码硬度固定为零，溶解项无效，因此不暴露不起作用的溶解系数。
+平坦地形的未定义归一化明确取坡度零，越界整数采样取零。
+联合调度始终读取最新完整阶段并发布最后一轮，未复制参考 C# 固定输出缓冲区
+及重置热侵蚀缓冲索引的问题；不承诺与原 Unity GPU 执行逐位相等。
+
+
+`waterField.exportChannel(target, channel)` 将一个完整水流通道原子写入同尺寸、
+有限的目标栅格，返回变化格子数的 Result；不调整尺寸，不保留引用，失败不修改目标。
+通道编号为 0 深度、1 X 速度、2 Z 速度、3 右向通量、4 左向通量、5 下向通量、6 上向通量。
+输出保留原始符号和单位，不取绝对值、不归一化。调用需独占目标且禁止并发修改水流场。
+Pcg 的 SimpleHeightBlend 读取红通道，因此原 WaterVelocity 遮罩对应 1，
+WaterFlux 对应 3，而不是速度长度或总通量。导出栅格可直接传给现有
+`transformMask` / `blendMask` 操作；完整 PaintContext UV 与原始地形混合仍需上层组合。
+
+
+### 空间笔刷混合
+
+`eve.TerrainBrushBlendSettings()` 配置独立的地形与笔刷仿射 UV。
+地形字段为 `heightXX`、`heightXZ`、`heightZX`、`heightZZ`、
+`heightOffsetX`、`heightOffsetZ`；笔刷字段为 `brushXX`、`brushXZ`、
+`brushZX`、`brushZZ`、`brushOffsetX`、`brushOffsetZ`。
+两个矩阵默认单位矩阵，偏移默认零，`strength=1`。
+坐标公式为 `(XX*u+XZ*v+offsetX, ZX*u+ZZ*v+offsetZ)`，输入 UV 是目标像素中心。
+
+`target.blendBrush(oldHeights, newHeights, brush, settings)` 返回变化格子数的 Result。
+三个输入可独立分辨率，采用 Clamp/Bilinear 像素中心采样；笔刷 UV 超出闭区间
+[0,1] 时输出采样后的旧地形，区间内输出 `lerp(old,new,strength*brush)`。
+权重不钳制，支持参考公式的外插；输入已是原生标量，不做 Unity 高度打包。
+所有栅格和系数必须有限，溢出不提交；目标可与输入别名，读取调用前快照。
+调用同步、无回调、不保留引用，调用方需独占目标并保证输入不被并发写入。
+这是 SimpleHeightBlend 的空间组合步骤，侵蚀遮罩的反转和后续滤镜仍需显式组合。
+
+
+### 强度滤镜与侵蚀遮罩组合
+
+`target.applyStrength(source, curve, mode, strength, invert)` 对同尺寸输入先查一行曲线，
+再按 invert 取 `1-curveValue`，然后计算模式结果，最后从输入向结果插值。
+mode 为 0 替换、1 最大值、2 最小值、3 相加、4 相减。参考 shader 将 0 命名为
+Multiply，但实际公式是替换曲线值，不是相乘。strength 必须在 [0,1]；结果不钳制。
+
+`target.generateErosionMask(oldHeights, erosion, brush, spatial, curve, mode, strength, userInvert)`
+先执行空间笔刷混合，再执行强度滤镜，按 Pcg 侵蚀分支将滤镜反转设为 `!userInvert`。
+erosion 是已计算的泥沙或通过 exportChannel 导出的右向通量/X 速度；此调用不推进模拟。
+spatial 为 TerrainBrushBlendSettings，曲线为有限非空一行栅格。
+两步整体原子提交，后一步失败也不会留下前一步结果；返回变化格子数的 Result。
+输入与目标允许别名，使用调用前快照；同步独占目标、输入不可并发修改，不保留引用或调用回调。
+该组合采用原生标量，仍需调用方根据世界/地形范围提供 UV 映射和模拟参数。
+
+
+### Grow/Shrink 遮罩
+
+`target.growShrinkMask(source, curve, distance)` 返回变化格子数的 Result。
+source 与 target 同尺寸且有限，curve 为有限非空一行强度曲线。
+distance 是世界距离除以操作范围所得的 UV 半径，正值增长、负值收缩；
+`2*abs(distance)*sourceWidth` 必须不超过 int 最大值以表达采样索引。
+两个方向步长均为 `1/sourceWidth`，X 外层、Z 内层遍历；每个候选值先按径向
+smoothstep 与当前累积值混合，再做最大/最小选择，因此不是普通形态学滤波。
+越界候选跳过，采样使用 Clamp/Bilinear 像素中心；最终经过 curve，距离零也不省略曲线。
+整数索引和 double 偏移明确定义采样序列，不复现 shader 浮点累加误差。
+最坏采样成本随半径增长；实现跳过确定越界区间，但不改变区间内的访问顺序。
+失败保留目标，别名输入读取快照。同步独占目标、不可并发修改输入，无回调或引用留存。
+
+
+### 曲率遮罩
+
+`eve.TerrainCurvatureSettings()`：`radius=0.001` 为 UV 模糊半径，`worldUnits=-400`
+缩放有符号高差，`intensity=0.7` 为正幂指数，`steps=32` 为每方向样本数，
+`directions=16` 为方向数。半径非负，采样数为正，乘积必须小于 INT_MAX。
+
+`target.generateCurvatureMask(input, heights, curve, settings, mode)` 返回变化格子数的 Result。
+目标与 input 同尺寸，heights 可独立分辨率，curve 为有限非空一行强度曲线。
+中心及各径向样本平均后，计算 `clamp(abs(pow((origin-blur)*worldUnits,intensity)),0,1)`，
+再查曲线并按 mode 混合：0 相乘、1 最大、2 特殊 Smaller、3 相加、4 相减。
+Smaller 的原公式是 `filter < 1-input ? filter : input`，可能增加输入，不能当作普通 min。
+该 shader 不使用 strength 或 invert。负底数的非整数幂显式失败；没有提前对底数取绝对值。
+正幂溢出的无穷幅值按曲率饱和公式变为 1，最终标量输出溢出则不提交。
+径向循环以整数索引固定样本数，不承诺原 shader 浮点循环的逐位等价。
+所有栅格和系数必须有限。输出别名读快照，失败原子保留目标；同步独占目标，
+输入禁止并发修改，不保留引用、无回调。径向模糊设计的 MIT 归属与许可保留在实现中。
+
+
+### 凹凸遮罩
+
+`eve.TerrainConcavitySettings()` 提供 `featureSize=10`（高度纹素距离）与
+`concavity=1`（有符号凹凸系数）。featureSize 为正有限且可表示为 uint32；
+邻域偏移取整数截断值，边缘衰减使用未截断值。
+
+`target.generateConcavityMask(input, heights, curve, settings, mode)` 返回变化格子数的 Result。
+目标与 input 同尺寸，heights 的坐标映射在两个轴上都使用 heightWidth/inputWidth，
+映射坐标须可表示为 uint32。曲线是有限非空一行数组，读取
+`floor(clamp(value,0,1)*(curveWidth-1))`，不做双线性曲线采样。
+mode 为 0 相乘、1 最大、2 最小、3 相加、4 相减，未加入 strength 或 invert。
+原计算的无符号邻域运算及包含 width/height 的上界保持；越界纹素读零，
+零长度梯度定义为零。边缘衰减后再倍增、钳制并查曲线。
+使用 double 中间值，不承诺原 GPU 逐位一致。所有输入有限，失败不提交目标；
+别名读调用前快照，同步独占目标，无回调或引用留存，输入不得并发修改。
+
+
+### 图像遮罩
+
+`eve.TerrainImageMaskSettings()` 提供 `offsetX=0`、`offsetZ=0`、`scaleX=1`、
+`scaleZ=1`、`rotation=0`（弧度）、`tiling=false`，以及选择颜色 `red=1`、
+`green=1`、`blue=1` 和 `accuracy=0`。缩放不能为零，accuracy 在 [0,1]，所有值有限。
+
+`target.generateImageMask(input, red, green, blue, alpha, curve, settings, filter, mode)`
+接收四个同尺寸有限 RGBA 标量平面，独立于目标分辨率；目标和 input 同尺寸。
+返回变化格子数的 Result，目标可与任意输入别名，所有失败均不提交。
+filter 为 0 RGB 最大通道（不是亮度）、1 Lab 颜色选择、2 红、3 绿、4 蓝、5 Alpha。
+mode 为 0 相乘、1 最大、2 最小、3 相加、4 相减，不额外使用 strength/invert。
+
+图像在目标像素中心做中心偏移、缩放和旋转后双线性采样；平铺保留源码负整数
+映射到 1 的约定。不平铺时范围外筛选值为零，再经过一行 curve，因此最终未必为零。
+颜色选择保留源码 sRGB→XYZ→Lab 与 CIE76 距离，距离钳制到 [0,100]；
+匹配条件严格为 `difference < (1-accuracy)*100`，命中后得到
+`1-difference/100*accuracy`。accuracy=1 连相同颜色也不命中。
+传入色彩数值不做隐式解码或额外色彩空间转换，Alpha 不参与 Lab 距离。
+调用同步独占目标，输入不得并发修改；无回调和引用留存，图像解码/GPU 资源仍由调用方管理。
+
+
+`eve.generateTerrainImageMaskFromImage(target, input, imageData, curve, settings, filter, mode)`
+是完整宿主的 ImageData 适配入口，返回变化格子数的 Result。目标可与 input/curve 别名。
+它按 ImageData 当前像素格式读取 RGBA 浮点平面，再调用相同图像遮罩核心；
+不额外做 sRGB 转换或垂直翻转。输入须为可读取且存储完整的图像，非有限像素、
+无效设置和尺寸不匹配都不会修改目标。同步独占目标，图像及输入不得并发修改；
+不保留 ImageData、像素指针或 GPU 资源。完整宿主需要 image 模块，核心裁剪配置
+继续使用 generateImageMask 的四平面接口，不隐式提供图像解码回退。
+
+### 碰撞遮罩栈
+
+`eve.TerrainCollisionMaskStack()` 接收调用方已经从场景、树或对象缓存烘焙出的有限标量栅格。
+`addLayer(mask,type,active,invert)` 深拷贝一层；type 为 0=RadiusTree、1=RadiusTag、
+2=LayerGameObject、3=LayerTree。`getLayerCount()` 包含禁用层，`clear()` 清空所有层。
+
+`apply(target,input,curve,mode)` 对每个输出像素按 Clamp/Bilinear 重采样所有 active 层，从白色开始依次
+取最小值，随后应用一行强度曲线和 ImageMask blend。Radius 类型在 `invert=true` 时反转；Pcg 的
+Layer baked texture 以白色表示占用，因此 Layer 类型使用相反的 invert 约定。目标与 input 尺寸一致，
+各层可使用不同分辨率；输入会被快照，允许 target alias。非法栅格、类型、模式或有限范围失败时不
+修改 target。栈不持有场景对象或渲染缓存；几何查询和缓存失效由场景/provider 负责。
+
+### 多边形笔刷遮罩
+
+`eve.TerrainPolygonMask()` 按顺序拥有控制节点。`addNode(worldX,worldZ,radius,strength)` 复制有限世界
+坐标、正半径和 strength 元数据；`getNodeCount()` 返回节点数，`clear()` 清空。`rasterize(target,brush,
+originX,originZ,spacingX,spacingZ,type)` 将节点绘制到目标网格，type 为 0=Open、1=Closed。Open 只绘制
+节点笔刷；Closed 在至少三个节点时先用 Pcg `SH_PolygonFill.shader` 相同的奇偶射线规则填白多边形，
+再按节点顺序叠加笔刷。每次叠加钳制上限到 1，并把小于 0.25 的结果清零。笔刷红通道由 Heightmap
+标量表示，节点方形范围外明确为零，范围内使用 Clamp/Bilinear 纹理中心采样。
+
+Pcg 4.2.2 的 `PolyMask.cs` 会把 `PolyMaskNode.Strength` 传给 `ApplyBrushStroke`，但该函数和
+`SH_AdditiveBrush.shader` 都不设置或读取 strength；EVEngine 保留字段以便资产转换，同时按该版本
+可观察行为不以它缩放笔刷。地形射线吸附、编辑器选择、可视化网格和缓存失效属于编辑器/provider，
+核心不持有场景对象。输出先在私有缓冲完成后一次发布，非法网格、类型、非有限值或间距失败不修改目标。
+
+### WorldBiome baked-mask cache
+
+`eve.TerrainBakedMaskCache()` 以 `(terrainId,maskGuid)` 为稳定复合键拥有已烘焙有限 Heightmap。
+`store` 深拷贝或原子替换条目并标记 fresh；`markDirty(maskGuid)` 使所有地形上的同 GUID 条目显式 stale；
+`copyMask` 仅导出 fresh 条目，并按目标分辨率使用 Clamp/Bilinear 采样。missing 与 dirty 都返回结构化
+NotFound，且保留旧输出。provider 完成世界图规则重算后再次 `store` 即重建条目。`erase` 删除精确复合键，
+`clear` 清空全部缓存，`getEntryCount` 包含 dirty 条目。
+
+这对应 Pcg `GetWorldBiomeMask`/`BakedMaskCache` 的缓存、跨分辨率 Graphics.Blit 与 GUID 失效边界。
+世界图规则求值和磁盘资产读取属于上层 provider；缓存不持有场景、Terrain、GPU texture、回调或文件句柄。
+provider 先销毁时 dirty/missing 明确失败，cache 先销毁时只释放其值副本；热重载通过 markDirty 后重新 store，
+不会把旧图无声当作当前结果。
+
+`ProcgenHeightmap.applyGlobalSpawnerMask(input,source,curve,settings,mode)` 对应 ImageMask 的
+`GlobalSpawnerMaskStack` 分支。source 是被引用 Spawner 的完整蒙版栈输出；接口把标量复制为通道语义，
+强制选取 Red，再复用 ImageMask 的 UV 偏移、缩放、旋转、tiling、强度曲线和五种 blend。settings.filter
+不会改变标量结果，其余字段按 `generateImageMask` 验证。调用只借用 source，不持有另一个 Spawner 或
+RenderTexture；目标与 input 可别名，失败时不发布部分结果。
+
+### NoiseMask
+
+`ProcgenHeightmap.generateNoiseMask(input,curve,settings,type,mode)` 生成 NoiseMask 并立即按强度曲线与
+五种 ImageMask blend 合并。type 为 0=Perlin、1=Value、2=Billow、3=Ridge、4=Voronoi。
+`TerrainNoiseMaskSettings` 提供 `translationX`、`translationZ`、`scaleX`、`scaleZ`、弧度 `rotation`、
+`octaves`、`amplitude`、`frequency`、`persistence`、`lacunarity`、`warpIterations`、`warpStrength`、
+`warpOffsetX`、`warpOffsetZ` 与显式 `seed`。
+octaves 和 warpIterations 支持 Pcg fBm 风格的分数最后一步，范围为 `[0,16]`；默认值来自包内
+PcgNoiseSettings/FbmFractalType。输出按固定扫描与固定 hash 流确定，不读取帧时钟或全局随机状态。
+
+本实现复用 EVEngine `NoiseField` 的 CPU hash/Perlin 基础，因此保留 Pcg 的五类形态、TRS、fBm 与 warp
+参数语义，但尚不声明与 Unity HLSL `sin` hash 逐像素相同；跨后端比较采用数值与形态容限。所有输入
+先验证并在私有缓冲计算，非法枚举、零 scale、非有限参数或溢出不修改目标。
+
+### Smooth ImageMask
+
+`ProcgenHeightmap.smoothMask(input,verticality,blurRadius)` 对应 ImageMask 的 Smooth 分支。它按
+`SmoothHeight.shader` 固定七对权重先水平再垂直处理；`verticality=-1` 只降低，`0` 取加权平均，`1`
+只抬高。垂直 pass 保留原 shader 使用 X texel size 的行为，非方形栅格也按该约定采样。shader 虽读取
+HeightTransformTex，但最终返回值没有使用它，因此该入口不接受强度曲线或额外 blend。
+
+
+### 世界坐标到笔刷 UV
+
+`eve.TerrainSampleGrid()` 描述高度纹理的样本中心，`width=1`、`height=1`；
+`setOrigin(x,z)` 设置首样本世界坐标，`setSpacing(x,z)` 设置正采样间距，默认均为 1。
+
+`spatial.configureWorld(world, contextWidth, contextHeight, heightGrid)` 将世界配置转换为
+TerrainBrushBlendSettings 的两个 UV 矩阵，返回变化系数数目的 Result。
+world 是 TerrainStampSettings：其 grid 描述目标首样本与间距，center/size/rotation
+描述笔刷世界矩形；高度操作、amplitude/baseHeight/blendStrength 不参与映射。
+heightGrid 描述传给 blendBrush 的旧高度纹理，spatial.strength 保持不变。
+
+转换显式处理半像素偏移，使相同网格生成单位高度 UV 映射；旋转以 X/Z 平面逆映射
+将世界位置变为笔刷坐标。C++ 先在 double 中计算原点差，再转换为有限 float 系数；
+Squirrel 当前是 float VM，传入大绝对坐标前需调用方完成世界原点偏移，不能恢复已丢失精度。
+尺寸、间距和笔刷范围必须为正，坐标有限；跨度或系数溢出时不修改 spatial。
+调用同步独占 spatial，不保留输入引用，也不会移动地形或修改任何栅格。
+
+
+### 地形生成会话
+
+`eve.TerrainGenerationSession()` 创建独立、初始为空的地形会话。支持记录原生印章和下述七种标量地形效果。
+`reset(baseline)` 复制有限基线并清空历史；`stamp(stamp, settings, operation, localMask, globalMask)`
+复制印章、设置和两个遮罩为命令输入，成功后追加记录。操作编号与 applyStamp 相同。
+`copyTerrain(output)` 将权威地形复制到同尺寸有限栅格；修改这个副本不会改变会话。
+
+`undo()`、`redo()` 改变已应用历史前缀并从基线回放，`replay()` 重算当前前缀。
+`setOperationEnabled(index, enabled)` 切换命令并重算；`operationEnabled(index)` 返回布尔值 Result。
+`getOperationCount()` 包含待重做的后缀，`getAppliedCount()` 包含前缀中的禁用命令。
+index 只是会话内索引，不是跨重置/分支的稳定 ID。撤销后成功追加新操作会截断重做后缀，
+追加失败不会截断；切换早期命令导致后续溢出时，历史和地形都保持原样。
+
+`setAccess(access)` 返回 void Result，0 为 Editable、1 为 Locked；`getAccess()` 返回当前策略。
+锁定拒绝 reset、stamp、undo、redo、replay 和命令开关，允许读取快照和解锁。
+其余修改操作返回变化地形样本数 Result，reset 返回基线样本数，失败返回结构化错误。
+所有状态由会话单独持有，公共读取为副本；调用在所属线程串行执行，无外部引用留存或回调。
+撤销/回放复制候选状态后完整重算，内存和耗时随历史输入大小增长；同一构建下用固定输入顺序
+保证浮点重算一致性，不依赖隐式时钟/RNG。不承诺跨平台逐位一致。
+这不是现有分块点集 RuntimeGeneration 调度器的替代，也不包含后台线程或其他操作种类。
+
+`snapshotJson()` 写出严格的 `eve.procgen.terrain-generation-session` schema version 1，拥有 baseline、
+全部命令输入与设置、enabled 标志、已应用 cursor 和访问策略。`restoreJson(json)` 拒绝未知根字段、
+版本、非法枚举、非有限数值、尺寸/数量越界、截断或尾随 payload；它先以全部命令启用验证完整历史，
+再按保存的 enabled/cursor 重建最终地形、泥沙和七个水通道，成功后一次交换。Pending 会话和 Locked
+目标拒绝恢复；快照不会保存临时 replay 候选，恢复后的调度状态为 Idle。
+
+调用方可用 `beginReplay()` 启动分步重放，再用 `stepReplay(maxOperations)` 按正数命令预算推进。
+状态枚举为 0=Idle、1=Pending、2=Completed、3=Cancelled、4=Failed；`getReplayStatus()` 和
+`getReplayCompletedOperations()` 可轮询当前生命周期与已访问命令数。Pending 阶段只修改私有候选，
+`copyTerrain`、`copySediment` 和 `exportWater` 继续返回最后一次已发布状态；完成全部命令时三类数据
+一次发布。`cancelReplay()` 丢弃 Pending 候选，失败也不修改权威状态。Pending 时拒绝历史编辑、访问
+策略切换和第二次 begin；取消或终态之后可以重新开始。这提供与 Pcg coroutine 对应的显式可观察
+调度边界，但由所属线程逐步驱动，不创建后台 worker，也不跨线程调用脚本。
+
+
+地形会话还提供 `contrast(mask,strength,featureSize)`、`smooth(mask,settings)`、
+`ridges(mask,settings)`、`terrace(mask,settings)`、`power(mask,power)`、
+`heightCurve(mask,curve,minimum,maximum)`、`heightMix(localMask,globalMask,settings)`。
+
+`eve.bakeTerrainCurveTexture(output, curve)` 将单行 Heightmap 曲线 LUT 写入单行 ImageData，
+对应 Pcg `TerrainToolsUtility.AnimationCurveToRenderTexture`。采样坐标为 `i / outputWidth`；
+为保持源实现行为，像素 0 保持透明黑，但返回范围从曲线在 0 的值开始计算。成功 Result 的
+`value` 包含 `minimum`、`maximum` 和 `writtenPixels`。输入必须是非空单行图像与有限单行曲线；
+失败不会改变输出图像。
+这些接口使用对应的 Terrain*Settings 和原生效果公式，复制栅格、曲线与设置作为历史输入；
+成功返回变化地形样本数 Result。所有命令共用锁定、禁用、撤销、重做和原子回放契约。
+修改调用方的遮罩或曲线不影响已有命令。混合历史重算失败时也不修改命令开关和当前地形。
+会话快照记录足以重建水流/泥沙状态的完整命令输入，但仍不记录异步资源操作。
+
+
+### TerrainGenerationSession 侵蚀历史
+
+`reset(baseline)` 现在同时初始化零泥沙、零水深、零速度和零通量。标量地形命令保留
+已有模拟状态；热侵蚀和水力侵蚀使用历史中前一步的状态。所有输出与历史一起原子发布，
+撤销、重做、禁用操作和回放覆盖全部通道。共享的内部候选结果仅为不可变快照，没有对外
+可写别名。调用者仍须在所属线程串行访问；时间步长和迭代次数显式传入。
+
+- `TerrainGenerationSession.resetSimulation(depth)`：记录可撤销的模拟重置，清零泥沙、
+  通量和速度，将水深设为有限非负值；地形不变。需要一次全新侵蚀时先调用它。
+- `TerrainGenerationSession.thermal(settings)`：记录热侵蚀，累积泥沙，保留水流状态。
+- `TerrainGenerationSession.hydraulic(water, sediment, thermal, iterations)`：记录完整水流、
+  泥沙、热侵蚀迭代；复制设置，延续已有模拟状态，不隐式应用 Unity UI 单位换算。
+- `TerrainGenerationSession.copySediment(output)`：复制当前有符号泥沙到匹配尺寸的有限高度图。
+- `TerrainGenerationSession.exportWater(output, channel)`：复制原始水流标量通道；整数通道
+  0=Depth、1=VelocityX、2=VelocityZ、3=FluxRight、4=FluxLeft、5=FluxBottom、6=FluxTop。
+
+新增修改方法均返回 `Result<int>` 的**地形变化样本数**；模拟状态改变但地形不变时可为 0。
+输出方法返回输出变化样本数，锁定时仍可读；修改方法在锁定时拒绝执行。
+非法输入、后续命令失败或分配异常不会提交部分模拟状态或截断重做历史。
+会话 reset 清空历史；resetSimulation 是历史中的命令，两者语义不同。
+该实现沿用前文记录的原生侵蚀内核约定，不复刻源 C# 包装层固定输出缓冲索引错误，
+不声明与未定义的 GPU 调度行为逐位一致。会话仍无异步世界创建或植被资源历史；分步重放
+只调度本会话已拥有的地形/侵蚀命令。
+
+
+### TerrainDetailLayer 整数草地密度
+
+`TerrainDetailLayer` 是独立的整数细节密度所有者，不是 `Grid2D` 的语义编号层。
+一个实例对应一张完整对齐的地形细节图，不持有资源注册表或图形对象。
+
+- `TerrainDetailLayer.reset(width, height, count)`：初始化正尺寸与非负整数数量，返回单元数。
+- `TerrainDetailLayer.getWidth()`、`TerrainDetailLayer.getHeight()`：查询尺寸，空实例返回 0。
+- `TerrainDetailLayer.sample(x, z)`：返回 `Result<int>` 的数量副本。
+- `TerrainDetailLayer.apply(fitness, settings, mode, seed)`：从匹配尺寸的有限 Heightmap 生成密度，
+  返回变化单元数。mode 为 0=Replace、1=Add、2=Remove；seed 为显式有符号 32 位随机种子。
+- `TerrainDetailSettings.minimumFitness`：严格适应度下限，默认 0.5，范围 [0,1]。
+- `TerrainDetailSettings.fadeStart`：低于此值按适应度概率稀疏，默认 0.6，范围 [0,1]。
+- `TerrainDetailSettings.density`：规则密度乘全局密度后的有效值，默认 16，有限非负且小于 INT_MAX。
+- `TerrainDetailSettings.namespaceId`：稳定资源层身份；零为兼容默认层，非零用于同一 terrain 上独立保存和清理多个 detail prototype。
+- `TerrainDetailPlacementSettings.densityNamespaceId`：选择要导出为实例的密度资源层；`namespaceId` 继续定义输出点及其 `spawnNamespace` 来源身份。
+
+Replace 先清零目标资源层；Add/Remove 保留未通过适应度或随机门槛的单元。通过的单元按
+`InverseLerp(minimumFitness,1,fitness)*density` 增减，然后钳制到 [0,density]，
+按最接近的偶数舍入。这意味着 Add 也可能降低原先超过目标密度的数量，这是源码行为。
+随机稀疏采用源码 XorshiftPlus（种子 0 按 1 处理，负种子按 uint32 位模式），X 外层、
+Z 内层遍历，只在适应度位于淡出带时抽样。每次 apply 重建独立 detail-thinning 流；
+同构建、相同整层输入和种子可重复，不承诺分割区域后仍与单次完整层调用一致。
+所有输入先验证，候选数量计算完再提交；失败或分配异常不改变原层。
+调用者在所属线程串行访问，不保留借用，也不提供可写数量视图。
+资源层由稳定 namespace 拥有；实际草叶生成和渲染通过下述 PointSet 导出及 graphics 接口完成。
+
+
+### 草地密度到 PointSet
+
+`eve.exportTerrainDetailPoints(output, layer, heights, settings)` 把 TerrainDetailLayer 的
+每个整数数量展开为现有 PointSet，成功返回发射点数，失败保持原 output 不变。
+高度图可以与密度图分辨率不同，端点覆盖同一世界矩形，双线性取样后乘高度比例。
+输出使用现有 `asset` 字符串属性，并记录 `detailCell`（行优先单元编号）和
+`detailOrdinal`（单元内序号）。资源引用只传递给下游，不在此加载资产。
+
+`TerrainDetailPlacementSettings` 字段：
+
+- `originX`、`originZ`：世界矩形起点，默认 0。
+- `width`、`depth`：正的世界宽度、深度，默认 1。
+- `heightScale`：有限高度比例，默认 1。
+- `minimumScale`、`maximumScale`：正的实例缩放范围，默认均为 1。
+- `seed`：位置、旋转、缩放三个独立命名随机流的显式 32 位种子，默认 1。
+- `namespaceId`：非零实例身份命名空间，默认 1；实际场景须按资源/瓦片分配不同值。
+- `maxPoints`：显式输出预算，默认 1000000，允许 0。超限拒绝整个输出，不截断。
+- `asset`：非空资源引用，必须由调用者指定。
+
+ID 来自命名空间、单元和单元内序号，与总密度及遍历行号无关。修改其他单元不会
+移动或重编号现有点；改变网格尺寸或命名空间改变身份范围。零 ID 保留，极端命名空间
+映射为零时明确失败，调用者应改用其他命名空间。位置采用单元内原生随机分布，
+朝向使用 Y 轴角度、法线向上；这部分替代 Unity 内部实例化，不宣称 Unity 位置一致。
+原输入只在本次调用借用，输出在私有 PointSet 完成后一次移动发布；没有场景对象
+所有权或回调。调用者在所属线程串行访问所有输入输出。
+
+
+### PointSet 草地渲染接入
+
+`eve.bakeTerrainGrass(field, points, asset, width, height)` 是完整宿主适配器：按 `asset`
+属性精确选择 PointSet 中的实例，保留其根位置与独立横向/纵向缩放，上传到既有 GrassField，
+返回 `Result<int>` 的上传数量。无匹配实例时清空已发布网格。非空资源选择器、有限
+根位置、正宽高、非零稳定 ID 以及大于 0.001 的横向/纵向缩放是前置条件；非法参数不改变
+现有可见草地。X/Z 缩放必须相同；Y 缩放独立，不再丢失草地宽高差异。
+
+内置路径采用 GrassField 四帧草地贴图；图像路径由调用者显式上传已解码资源，asset
+只做分组选择。64 位身份留在 PointSet；未染色实例折叠为可精确存入 float 的 24 位
+动画相位键，染色实例把 RGB 量化为 RGB8 并由局部根坐标生成动画相位，因此整体模型
+变换不会改变风相位。这不是场景对象身份的替代。法线和 yaw 不参与当前向上 billboard 的构建。
+
+C++ `GrassField::bakePoints(points,width,height)` 接受已有 `grass::Point` 数组，不再
+进行 Poisson 重新采样。CPU 验证/网格构建及 GPU 创建在发布字段前完成；失败保持
+原字段。新增 GPU 对象按现有约定由 Graphics 管理到其析构，包括中断上传产生的对象。
+调用必须发生在 Graphics 所属线程、draw/capture 回调之外；不保留输入数组或 PointSet。
+此适配器需要完整 graphics provider，核心裁剪构建只包含密度与 PointSet 算法。
+
+
+`eve.bakeTerrainGrassImage(field, points, asset, width, height, image)` 使用一张已有
+RGBA8 ImageData 替代内置动画 atlas。实例分组选取和失败原子性与 bakeTerrainGrass
+相同，图像必须具有完整 RGBA8 存储；包括空点组也先校验图像。上传保留 RGB/alpha，
+不合成帧、不使用 RGB 推断透明度，采用单帧 UV 和中性白色/灰色明暗调制。
+原图仅在上传期间借用，GPU 纹理由 Graphics 拥有。C++ 对应
+`GrassField::bakeTexturedPoints(points,width,height,image)`，与内置路径共享同一发布实现。
+该图像 billboard 支持类型化风参数和健康/枯萎颜色；颜色 alpha 仍由纹理所有。
+`eve.bakeTerrainGrassFoliage(field,points,asset,width,height,albedo,normal,mask,settings)` 提供
+Pcg/PW 静态植被材质路径。三张图必须是同尺寸完整 RGBA8；遮罩通道为 metallic、occlusion、
+thickness、smoothness。`GrassFoliageSettings` 控制线性色调、alpha cutoff、normal strength、相机距离
+淡出和高度雪覆盖。EVEngine 使用自身方向光、环境光与级联阴影合同，未复制 Unity Standard 内部实现。
+全部 DetailRenderMode 仍不属于此适配器。
+
+
+独立宽高参数：`TerrainDetailPlacementSettings.minimumWidth`、`maximumWidth`、
+`minimumHeight`、`maximumHeight` 默认均为 1，都是正有限乘数，最大值不得小于最小值。
+分别用 width/height 命名随机流选择，与已有 minimumScale/maximumScale 统一比例相乘；
+输出 X/Z 为横向比例、Y 为纵向比例。修改宽高范围不改变位置、朝向、ID 或其他单元。
+乘积不能用正 float 表示时拒绝完整输出。实际物理宽高还要乘上传时传入的 billboard 宽高。
+
+颜色参数 `healthyR`、`healthyG`、`healthyB`、`healthyA`、`dryR`、`dryG`、`dryB`、`dryA`
+均为线性 [0,1] 端点；`noiseSpread` 为 [0,1]，
+`noiseSeed` 为显式有符号 32 位种子。每个点按世界矩形内的归一化坐标采样确定性的平滑
+格点噪声，再在 dry 与 healthy 之间插值。`noiseSpread=0` 固定取中点。该噪声是对 Unity
+Terrain 内部不可见实现的原生重建，保证 EVEngine 内重放稳定，不声明与 Unity 数值逐点一致。
+颜色配置不参与位置、缩放或稳定 ID；任何非法端点或 spread 都在发布前拒绝并保留旧输出。
+
+### 地形树木放置
+
+`eve.exportTerrainTreePoints(output, fitness, heights, settings)` 将一张归一化适应度图与独立
+分辨率的高度图展开为带资源属性的 PointSet。它按 `spacing / spawnDensity` 扫描世界矩形，
+并使用 Pcg XorshiftPlus 相同的条件抽样顺序执行 `failureRate`、`jitterPercent`、
+`minimumFitness` 羽化、缩放随机值、Y 偏移和 0..360 度朝向。成功返回实例数；任何非法
+配置、超出 `maxPoints` 或属性发布错误都保留旧 output。
+
+`TerrainTreePlacementSettings` 包含以下脚本字段：`originX`、`originZ`、`width`、`depth`、
+`heightScale`、`spacing`、`spawnDensity`、`jitterPercent`、`failureRate`、`minimumFitness`、
+`snapToTerrain`、`seaLevel`、`customOffset`、`minimumYOffset`、`maximumYOffset`、
+`minimumWidth`、`maximumWidth`、`minimumHeight`、`maximumHeight`、`widthRandomPercentage`、
+`heightRandomPercentage`、`healthyR`、`healthyG`、`healthyB`、`healthyA`、`dryR`、`dryG`、
+`dryB`、`dryA`、`bendFactor`、`boundsRadius`、`seed`、`namespaceId`、`maxPoints` 和 `asset`。
+
+`setScaleMode(mode)` / `getScaleMode()` 使用 0=Fixed、1=Fitness、2=Random、
+3=FitnessRandomized。`setYOffsetMode(mode)` / `getYOffsetMode()` 使用 0=TerrainHeight、
+1=SeaLevel、2=Custom。`snapToTerrain=true` 总是采用采样地形高度；关闭后才按 Y 模式选择
+地形、海平面或自定义基准，再叠加随机偏移。
+
+输出点携带世界位置、独立宽高、yaw、适应度颜色、局部 bounds，以及 `asset`、
+`treeCandidate`、`bendFactor` 属性。稳定 ID 由 namespace 和扫描单元生成；修改外观、颜色
+或缩放范围不改变实例身份和位置。当前 `bendFactor` 是供树木材质/风适配器读取的下游
+元数据；调用者可按原型创建 `gfx.newTreeWindShader()`、配置 `eve.TreeWindProfile`，再把同一
+shader 赋给该原型的 Renderable3D。显式适配避免普通 Renderable3D 猜测资源类型或引入第二份
+原型状态。
+
+`eve.removeTerrainTreePoints(output, input, fitness, settings)` 实现 Pcg Remove：仅处理
+`asset` 匹配且位于配置矩形内的点，在当前 fitness **严格大于** `minimumFitness` 时移除，
+并完整保留其他资源、矩形外点、行顺序和属性。output 可以与 input 是同一 PointSet。
+
+`TerrainTreeRescaleSettings` 与 `eve.rescaleTerrainTreePoints(output, input, settings)` 实现
+原型刷新。字段 `previousMinimumWidth`、`previousMaximumWidth`、`previousMinimumHeight`、
+`previousMaximumHeight` 描述上次生成区间；`minimumWidth`、`maximumWidth`、`minimumHeight`、
+`maximumHeight`、`bendFactor`、`boundsRadius`、`asset` 描述新原型。它也提供
+`setScaleMode()` / `getScaleMode()`。Fixed 直接采用新最小值；其他模式按旧区间
+InverseLerp 并钳制到 [0,1]，再映射到新区间，与 Pcg 原型刷新逻辑一致。刷新只改变匹配
+点的宽高、bounds 和 bendFactor；身份、位置、旋转、颜色及其他属性保持不变，失败不发布。
+
+`grass::Point.widthScale` 为独立横向比例，0 表示沿用已有 height scale；直接上传时
+非零值须大于 0.001。内部顶点 normal.z 保留旧 0/1 的等比编码，新横向比例 w 在
+普通层编码为 -w、暗层编码为 1+w。Vulkan/WGSL 都先解码宽度和层标记，再各自应用
+横向、纵向比例；正的小比例不再被 shader 强制抬到 0.05。此为运行时网格编码，
+未引入持久格式或新的权威数据副本。
+
+### 多地形高度图事务
+
+`mapTerrainOperationMultiTile(tiles,settings,domain,worldMap,names)` 提供不修改资源的通用 C++
+窗口计算。`TerrainOperationTile` 只描述名称、世界矩形、二维分辨率和地图域；返回值沿输入顺序给出
+每块 tile 的 local/operation 像素矩形。`Heightmap` 域按 Pcg 规则使用 `resolution-1` 的 tile
+步长并补一个共享接缝像素；`Texture`、`TerrainDetail`、`Tree`、`GameObject` 与 `BakedMask`
+使用完整 resolution，边界没有重复单元。不同域因此可共享筛选、旋转 AABB、白名单和溢出检查，
+同时保留各自正确的接缝语义。
+
+`applyTerrainStampMultiTile(tiles,stamp,settings,localMask,globalMask,worldMap,names)` 是 C++
+批量入口。每个 `TerrainHeightTile` 提供唯一名称、借用 Heightmap、世界原点/尺寸以及普通或
+world-map 域。所有 tile 必须使用相同高度图分辨率和世界像素间距，原点按完整 tile 跨度对齐；
+不同分辨率不再像 Pcg 那样静默跳过，而是返回 InvalidArgument 并保持全部 tile。
+
+操作像素范围遵循 Pcg MultiTerrainOperation 的高度图规则：世界范围以 floor/ceil 转为像素，
+使用 `resolution-1` 作为相邻 tile 偏移，并包含共享接缝像素。仅与旋转矩形 AABB 边缘接触的
+邻 tile 不计入；实际修改仍由旋转 stamp 精确判断。普通与 world-map tile 分域，C++ 可传精确
+名称 allow-list。报告包含 operation 矩形、各 tile 的 local/operation 矩形、受影响 tile 数与
+改变样本数。
+
+`eve.TerrainMultiTileWorkspace()` 是拥有式脚本会话。`addTile(name,heightmap,x,z,width,depth,worldMap)`
+复制输入；成功 stamp 后 topology 固定。`stamp(stamp,settings,operation,localMask,globalMask,worldMap)`
+先复制整个工作区，在候选 tile 上完成所有计算、报告和历史分配后整体交换。任何晚期数值或
+分配失败都不会留下部分 tile。`copyTile` 只导出副本；`undo`/`redo` 恢复所有 tile 与对应报告，
+在 undo 后 stamp 会截断 redo 分支。`getTileCount`、`getLastAffectedTiles`、
+`getLastChangedSamples`、`getLastMappingCount`、`getOperationCount` 和 `getAppliedCount` 提供只读状态。
+
+`applyTerrainDetailMultiTile(tiles,operationFitness,detailSettings,operationSettings,seed,worldMap,names)`
+把通用窗口直接用于细节层。共享 fitness raster 的尺寸必须等于计算出的 operation 矩形；每块
+`TerrainDetailLayer` 先复制后计算，全部成功才共同发布。Replace 与 Pcg 一致：受影响 tile 的旧层
+先整体清零，只在映射矩形内生成；Add/Remove 保留矩形外数据。所有 tile 按描述符顺序共享同一个
+显式 XorshiftPlus 流，因此淡出带的条件随机抽样不会在 tile 边界重新播种。
+
+脚本使用 `eve.TerrainMultiDetailWorkspace()`。`addTile` 复制输入层，`apply` 接受共享 fitness、
+detail settings、世界操作矩形、mode、seed 与地图域；`copyTile` 导出独立副本。`undo`/`redo`
+恢复所有层及其报告，undo 后的新 apply 截断 redo 分支。只读计数接口与高度图工作区保持一致。
+两个会话都单线程拥有全部状态，不保留外部 raster、场景对象、回调或隐藏时间/RNG。
+
+`applyTerrainTreesMultiTile` 将 Tree-domain operation raster 应用于多个 `PointSet`。Add/Replace
+沿用 Pcg `SetTerrainTrees` 在该阶段的追加语义，Remove 仅删除 operation 矩形内匹配 asset 且
+fitness 严格超过阈值的点。所有 tile 共用 settings.seed 初始化的一个 XorshiftPlus 流；扫描范围
+在局部窗口末端增加一个生成步长，使 jitter 能从 tile 外回落到边缘。全部候选 PointSet、属性和
+总数完成后才共同发布。
+
+脚本使用 `eve.TerrainMultiTreeWorkspace()` 深拷贝每块 tile 的初始 PointSet 与高度图；`apply`
+的 mode 为 0=Add、1=Replace、2=Remove。`copyTile`、`undo`、`redo` 和统计接口与其他多地形
+工作区一致，历史快照同时覆盖所有 tree owner。
+
+### 地形对象规则
+
+`TerrainObjectPlacementSettings` 对应 Pcg `ResourceProtoGameObject` 与 SpawnRule 的外层扫描；
+一个 prototype 可通过 `addInstance(TerrainObjectInstanceSettings)` 添加多个子资源。每个子资源
+独立配置数量区间、失败率、XYZ 偏移、地形/海平面/自定义 Y 基准、固定/随机/fitness/
+fitness-randomized 缩放、XYZ 旋转、沿坡面 Y 偏移、前向坡度对齐及完整坡度旋转。
+
+外层脚本字段包括 `originX`、`originZ`、`width`、`depth`、`heightScale`、`spacing`、
+`spawnDensity`、`jitterPercent`、`startOffsetX`、`startOffsetZ`、`failureRate`、`minimumFitness`、
+`minimumInstanceFitness`、`minimumDirection`、`maximumDirection`、`boundsRadius`、
+`boundsCheckQuality`、`prototypeScale`、`boundsCollisionCheck`、`seaLevel`、`seed`、`namespaceId`、
+`maxPoints` 与 `prototype`。子资源字段包括 `asset`、`minimumInstances`、`maximumInstances`、
+`failureRate`、`minimumOffsetX`、`maximumOffsetX`、`minimumOffsetY`、`maximumOffsetY`、
+`minimumOffsetZ`、`maximumOffsetZ`、`customOffset`、`commonScale`、`minimumScale`、`maximumScale`、
+`minimumScaleX`、`maximumScaleX`、`minimumScaleY`、`maximumScaleY`、`minimumScaleZ`、
+`maximumScaleZ`、`scaleRandomPercentage`、`scaleRandomPercentageX`、`scaleRandomPercentageY`、
+`scaleRandomPercentageZ`、`minimumRotationX`、`maximumRotationX`、`minimumRotationY`、
+`maximumRotationY`、`minimumRotationZ`、`maximumRotationZ`、`yOffsetAlongSlope`、
+`alignForwardToSlope` 与 `rotateToSlope`。`setScaleMode` 和 `setYOffsetMode` 接受对应枚举序号。
+
+`exportPoints(output,fitness,heights)` 使用一个显式 Pcg XorshiftPlus 流，依次执行规则失败、
+半幅 jitter、中心 fitness、自碰撞、bounds 范围平均 fitness、方向、子资源数量与失败、偏移后
+fitness、缩放、Y 偏移和旋转。结果进入原生 PointSet，携带 `asset`、`objectPrototype`、
+`objectCandidate`、`objectResource`、法线、变换和 bounds。稳定 ID 来自 namespace、候选位置、
+资源序号和实例序号；资产解析与 Scene/ECS 所有权由下游负责。`removePoints` 按 prototype、
+世界矩形和严格大于阈值的 fitness 原子删除。
+
+跨地形版本使用 `eve.TerrainMultiObjectWorkspace()`。`addTile` 深拷贝 PointSet 与高度图；
+`apply(fitness,settings,operation,mode,worldMap)` 的 mode 为 0=Add、1=Replace、2=Remove。
+所有映射 tile 按确定顺序共享一个 seed 随机流及一个自碰撞中心集合，因此接缝不会重新播种或
+允许重叠。Replace 先删除操作窗口内同 prototype 的旧点再生成；Remove 只删除 fitness 严格大于
+`minimumFitness` 的匹配点。`copyTile`、`undo`、`redo` 和统计方法与其他拥有式工作区一致。
+工作区不保留外部指针，且一次操作的所有 PointSet 和历史只在成功后整体发布。
+
+坡度对齐在 EVEngine 中由采样地形法线推导 Euler 旋转；它保持 Pcg 的选项和数据依赖，但不声明
+与 Unity Quaternion 组合逐位相同。bounds 范围 fitness 使用 EVEngine 明确定义的含边界栅格采样。
+
+### 地形纹理层权重
+
+`eve.TerrainSplatmap()` 拥有任意层数的浮点权重。`initialize(width,height,layers,defaultLayer)`
+建立唯一 topology 并把全部权重赋给默认层；`paint(paint,layer)` 以同尺寸归一化 Heightmap 覆盖
+目标层，其他层保持相对比例并共同归一化。原目标层为 1、其他层全零时，剩余权重确定性均分；
+单层 splatmap 只能保持权重 1。所有 texel 先在候选缓冲计算，再一次发布。
+
+`copyLayer(layer,output)` 将一个有效层完整复制到同尺寸 Heightmap，并返回变化样本数。这是 Pcg
+ImageMask `TerrainTexture` 分支的原生数据桥：调用方按稳定资源引用解析出层，再把该标量图交给
+`generateImageMask` 的变换、曲线和混合阶段。层不存在或输出 topology 不匹配时不修改 output；
+返回的是独立副本，后续绘制 splatmap 不会隐式改变已导出的遮罩。
+
+`eve.TerrainTextureAlignSettings()` 以 `terrainAOriginX`、`terrainAOriginZ`、`terrainAWidth`、
+`terrainADepth`、`terrainBOriginX`、`terrainBOriginZ`、`terrainBWidth`、`terrainBDepth` 保存两块
+地形的世界原点和尺寸，并提供 `blendStrength`、`blendWidth`、`adjacencyTolerance`。默认相邻容差
+为 Pcg 的 1.5 世界单位。`eve.alignTerrainSplatTextures(a,b,settings)` 按 Pcg `TerrainTextureAligner` 的边定义
+识别 X/Z 相邻关系，在边缘向内逐行执行 SmoothStep 衰减及同步二维噪声调制的双向层混合，并逐像素
+重新归一化。两张 splatmap 使用私有候选副本，只有完整成功后才同时发布；非相邻、自别名、非法
+几何或参数不会留下单边修改。返回值是两张图合计发生变化的 texel 数。
+
+C++ `paintTerrainSplatLayerMultiTile` 使用 Texture-domain 窗口将一张共享 operation raster 映射到
+多块 `TerrainSplatmap`，验证不同 tile 的所有 owner、topology、目标层及操作尺寸后统一提交。
+脚本 `eve.TerrainMultiSplatWorkspace()` 深拷贝每块 splatmap；`paint`、`copyTile`、`undo`、`redo`
+和统计接口与高度、detail、tree 工作区采用相同事务语义，历史快照同时恢复全部纹理层。
+该公式依据 Pcg `SetSplatmap` 对 Unity `CopyTerrainLayer` pass 1 的数据流重建；Unity 内置 shader
+源码不在 Pcg 包中，因此不声明逐位 GPU 等价。
+
+### 相邻地形高度缝合
+
+`eve.TerrainHeightStitchSettings()` 提供 `extraSeamSize` 和 `maxDifference`；后者保留 Pcg profile
+字段，但 Pcg 4.2.2 当前活动算法同样没有读取它。`TerrainMultiTileWorkspace.stitch(terrainA,terrainB,settings)`
+按两块地形原点差选择 North、South、West 或 East，验证共享边、分辨率、采样间距和栅格对齐，再复现
+`StitchBordersWithSeam`：从两侧内边界建立线性高度，向接缝逐点增加混合权重，最终用最靠近接缝的
+两个点平均并写入两侧共享边。操作成功后形成一个覆盖全部 owned tile 的 undo/redo 快照。
+
+C++ `stitchTerrainHeightmaps(a,b,settings)` 可用于已有编辑事务；它同步借用两个不同 Heightmap，先在
+两个候选副本完成计算，再同时发布。无共同边、部分边未按样本对齐、非法 seam 或非有限数据不会修改输入。
+
+`TerrainWorldWorkspace.setHeightWorldUnits(heightWorldUnits,worldHeightSpan)` 对应 Pcg Terrain Height
+Adjuster。它将目标值转换为 `clamp(heightWorldUnits/worldHeightSpan,0,1)`，覆盖工作区内每块地形的
+全部归一化高度，并将整个世界作为一次可撤销事务发布。成功值是实际变化的样本总数；非有限高度、
+非有限或非正垂直尺寸在创建候选状态前失败。
+
+`eve.TerrainSplatPalette()` 用 `addColor(r,g,b,a)` 按层添加归一化线性颜色，`getColorCount()` 返回
+当前颜色数；颜色数必须与 splat
+层数相同。`eve.bakeTerrainSplatAlbedo(output,splatmap,palette)` 将全部层权重混合进同尺寸可写
+`ImageData`，成功时返回像素数。实现先写私有 ImageData 副本再 adopt，因此 palette、尺寸或格式
+验证失败不会改变旧图像。生成的 RGBA8 可直接传给 `gfx.newTexture`，示例右侧 terrain 已使用此路径。
+
+`eve.GtsHeightBlendSet()` 按 splat 层顺序拥有原始高度 raster，并通过
+`addLayer(height,contrast,brightness,increase)` 保存 GTS alpha 高度变换。层数限制为 1–8，输入会复制。
+`eve.applyGtsHeightBlend(output,input,set,blendFactor)` 先计算每层“变换后高度 × 原权重”，再执行 GTS 的
+最大高度、transition、epsilon 与归一化公式，一次发布所有层权重。失败时 output 保持不变。
+
+`eve.GtsPackedLayerSettings()` 配置 `triPlanar`、`stochastic`、`triPlanarSizeX`、`triPlanarSizeZ`、`tileSizeX`、`tileSizeZ`、`offsetX`、`offsetZ`、`tintR`、`tintG`、
+`tintB`、`normalStrength`、`aoMin`、`aoMax`、`smoothnessMin`、`smoothnessMax`、`geoAmount` 和
+`detailAmount`，以及 `heightContrast`、`heightBrightness`、`heightIncrease`、`displacementContrast`、
+`displacementBrightness`、`displacementIncrease` 和 `tessellationAmount`。`GtsPackedLayerSet.addLayer` 复制每层
+albedo+height 与 normal+AO+smoothness 纹理；`eve.bakeGtsPackedLayers` 按归一化 splat 权重重复双线性采样
+并一次生成 albedo、renderer-ready packed normal、geological strength 和 detail strength。平面路径使用地形
+局部 UV；stochastic 路径复现 GTS 的 `TriangleGrid` 与固定 sin/hash 偏移；triplanar 路径使用世界空间
+`ZY/XZ/XY` 投影、`(4,15,4)` 法线指数、轴符号翻转、`0.33/0.67` 偏移，并按 C# 上传规则将 size 乘 10。
+四个输出原子提交。
+`eve.bakeGtsPackedLayerDisplacement(displacement,tessellation,heights,splat,layers,cameraX,cameraY,cameraZ,
+tessellationMultiplier,originX,originY,originZ,spacingX,spacingZ)` 对权重最高的四层复用同一平面 UV，读取
+albedo alpha 并按每层 displacement 参数变换，再分别加权位移和 tessellation amount。它复现 GTS shader
+的 100000 平方距离硬截止，并在最后乘全局 tessellation multiplier；相机和地形变换均为显式输入。
+两个 Heightmap 原子提交，随后传给 weather PBR 时雪位移按原 shader 顺序覆盖混合。
+
+`eve.generateGtsGlobalBlendDistance(output,heights,cameraX,cameraY,cameraZ,blendDistance,blendRange,
+originX,originY,originZ,spacingX,spacingZ)` 精确生成 GTS 共用的近远混合 raster：世界空间相机距离平方乘
+`blendDistance/10000`，饱和后取 `blendRange` 次幂。相机位置和地形变换全部显式输入，便于回放时在同一
+相机状态重建；失败保留旧 output。
+
+`eve.GtsColorMapSettings()` 配置 `alphaIntensity`、`colorIntensity`、`nearIntensity` 与
+`farIntensity`。`eve.bakeGtsColorMapAlbedo(output,colorMap,globalBlendDistance,settings)` 使用与输出同尺寸的
+颜色图及归一化近远混合 Heightmap，按 GTS 公式限制颜色和 alpha 后混入现有 albedo。它应在天气层之前调用。
+`eve.GtsMacroVariationSettings()` 配置三档 `sizeA/B/C`、最低亮度 `intensity` 和 `objectSpace`；
+`eve.bakeGtsMacroVariationAlbedo(output,map,settings,originX,originZ,spacingX,spacingZ)` 按
+`sizeA/1000`、`sizeB/10000`、`sizeC/100000` 三次重复双线性采样红通道并相乘，随后在天气层之后调制
+albedo。两个步骤均同步、原子，不读取相机或隐藏时钟。
+
+`eve.GtsGeologicalSettings()` 保存 GTS Geological 的 `enabled`、`objectSpace`、`nearStrength`、
+`nearNormalStrength`、`nearScale`、`nearOffset`、`farStrength`、`farNormalStrength`、`farScale` 和
+`farOffset`。`eve.bakeGtsGeologicalSurface(albedo,packedNormal,
+heights,layerStrength,globalBlendDistance,geoAlbedo,geoNormal,settings,originY)` 沿地形高度轴重复采样 near/far
+颜色条和 DXT5nm 法线条，用显式的逐像素地质层强度及近远距离混合它们。颜色图在 `[0,1]` 饱和，法线结果
+继续保持 renderer-ready packed RG，原有 AO 与 smoothness 通道不变。albedo 与 packedNormal 使用候选副本
+一起提交，任一 raster、纹理或参数非法时两者都不改变。
+
+`eve.GtsDetailNormalSettings()` 提供 `enabled`、`objectSpace`、`nearTiling`、`nearStrength`、
+`farTiling` 与 `farStrength`。`eve.bakeGtsDetailSurface(albedo,packedNormal,detailGreyscale,
+layerStrength,globalBlendDistance,detailNormal,settings,originX,originZ,spacingX,spacingZ)` 以世界或对象 XZ
+坐标进行 near/far repeat-bilinear 采样，按距离混合 RG 法线，再以逐像素层权重叠加到 packed normal。
+它同时按 GTS 的法线 XY 平方长度给基础 albedo 添加微阴影，并输出未加权 `detailGreyscale`。
+随后用 `eve.bakeGtsWeatherAlbedoDetailed(...,detailGreyscale,originX,originZ,spacingX,spacingZ)` 可复现 GTS
+对雪纹理额外施加的细节衰减。三个 detail 输出一起提交，失败不产生半更新。
+
+`eve.GtsSnowSurfaceSettings()` 和 `eve.GtsRainSurfaceSettings()` 保存 GTS profile 的表面天气参数。
+雪参数为 `enabled`、`power`、`minimumHeight`、`blendRange`、`slopeBlend`、`age`、`scale`、
+`colorR`、`colorG`、`colorB`；雨参数为 `enabled`、`power`、`minimumHeight`、`maximumHeight`、
+`darkness`。
+`eve.bakeGtsWeatherAlbedo(output,heights,snowAlbedo,snowMask,snow,rain,originX,originZ,spacingX,spacingZ)`
+按 GTS 顺序先混合雪色，再施加雨水变暗。雪使用世界高度平滑带、由高度梯度求得的坡度遮罩、积雪年龄、
+强度、重复纹理和 tint；雨使用最小/最大高度各 30 个世界单位的固定过渡，并将强度限制为 0.9。
+调用同步且原子，失败保留旧 output。
+
+`eve.bakeGtsWeatherPbr(normal,mask,displacement,tessellation,heights,snowNormal,snowMask,rainData,snow,rain,timeSeconds,originX,originZ,spacingX,spacingZ)`
+补充 GTS 的其余表面输出。`normal` 采用可直接交给 `Renderable3D.setNormalTexture` 的 packed 格式：
+RG 是以 `[0,1]` 编码的切线法线 XY，B 是 AO，A 是 smoothness；绑定后调用
+`setPackedNormalMask(true)` 让 Vulkan/WGSL 重建法线 Z 并逐像素读取 AO/光滑度。`mask` 同时保留原始
+四通道 GTS 材质数据，两个 Heightmap 分别保存位移与细分强度。雪支持 `normalStrength`、`setMaskRemapMin`、
+`setMaskRemapMax`、`heightContrast`、`heightBrightness`、`heightIncrease`、`displacementContrast`、
+`displacementBrightness`、`displacementIncrease` 和 `tessellationAmount`。雨支持 `speed`、`smoothness`
+和 `scale`。雨滴相位只读取显式 `timeSeconds`，因此回放不会依赖隐藏引擎时钟。四个输出先在私有副本
+完成，任一纹理、数值或结果非法时全部保持原状。
+
+### 世界创建与统一历史
+
+`eve.TerrainWorldCreationSettings()` 对应 Pcg `WorldCreationSettings` 的运行时拓扑字段：`tilesX`、
+`tilesZ`、`tileSize`、`tileHeight`、`centerX`、`centerZ`、`heightmapResolution`、
+`controlTextureResolution`、`detailResolution`、`treeResolution`、`objectResolution`、`splatLayers`、
+`defaultSplatLayer`、`defaultDetailDensity`、`worldMap`、`namePrefix` 与 `nameSuffix`。高度分辨率必须为
+`2^n+1`，control/detail 分辨率必须为 `2^n`。tile 原点按 Pcg 公式从完整世界中心向负半轴偏移；
+普通名称为 `prefix_x_z-suffix`，world-map 使用 Pcg 的 `World Map_x_z-suffix` 前缀。
+
+`eve.TerrainWorldWorkspace()` 同时拥有每块 tile 的 Heightmap、TerrainSplatmap、TerrainDetailLayer、
+tree PointSet 与 object PointSet。`create` 原子建立零高度世界；`stamp`、`paintSplat`、`applyDetail`、
+`applyTrees`、`applyObjects` 复用对应多 tile 内核。每次成功操作的历史快照覆盖五个领域，故
+`undo`/`redo` 不会产生从未共同存在过的高度与资源组合。`copyHeightmap`、`copySplatmap`、
+`copyDetail`、`copyTrees`、`copyObjects` 仅导出独立副本；tile 名称和原点查询返回结构化 Result。
+工作区单线程拥有状态，不保留外部 raster、回调、场景对象或隐藏时间源。
+
+`flatten()` 对所有 tile 的高度执行 Pcg 式归零并形成一次可撤销操作。`TerrainWorldClearSettings()`
+通过 `details`、`trees`、`objects`、`probes` 选择生成域，`clearSpawns(settings)` 在所有 tile 上一次性清除所选域；
+至少要选择一项。`sourceNamespace=0` 清理任意来源；非零时只清理由对应 detail/tree/object/probe placement
+`namespaceId` 生成的资源层或实例。`TerrainDetailLayer.sampleResource(namespaceId,x,z)` 查询单个资源层，`clearResource(namespaceId)`
+只删除该层并返回发生变化的单元数；普通 `sample` 返回所有资源层之和。Splat 权重不属于 Pcg
+`ClearSpawns`，因此不会被该操作修改。
+
+查询 API 为 `getTileName(index)`、`getTileOriginX(index)`、`getTileOriginZ(index)`、`getTileCount()`、
+`getLastChangedSamples()`、`getLastAffectedTiles()`、`getOperationCount()` 与 `getAppliedCount()`。
+
+### 有序 Spawner 计划
+
+`eve.TerrainSpawnPlan()` 以添加顺序拥有 terrain modifier stamp、texture、detail、tree 和 object 规则。
+`addSplat`、`addDetail`、`addTrees`、`addObjects` 接收稳定且唯一的 `ruleId`，并深拷贝 paint/fitness raster、
+领域设置、操作窗口、目标纹理层、模式和显式种子；
+之后修改调用方对象不会改变计划。`setEnabled(ruleId,enabled)` 按稳定身份切换规则，`getRuleCount()`
+返回规则总数。
+
+`addModifierStamp(ruleId,stamp,settings,operation,localMask,globalMask)` 加入 Pcg TerrainModifierStamp 资源，
+其中 operation 使用与 `applyStamp` 相同的 0..5 枚举。
+印章及局部/全局蒙版均在加入时深拷贝，并与其他资源规则按同一顺序事务执行。
+
+`TerrainWorldWorkspace.spawn(plan)` 按顺序执行全部启用规则，但只复制一次完整世界并只发布一次；任意
+后续规则失败会丢弃此前规则的候选结果，历史中只出现一个混合生成操作。空计划或全部禁用的计划会
+返回结构化失败，不制造无意义历史。执行仍使用各领域的跨 tile 映射、稳定资源 namespace 和显式 RNG。
+
+`snapshotJson()` 输出确定性的 `eve.procgen.terrain-spawn-plan` schema version 3 JSON。根对象严格只允许
+`schema`、`version`、`payload`；payload 是完整规则、raster、设置、顺序与启用状态的固定小端二进制
+十六进制表示。`restoreJson(json)` 拒绝未知根字段、未知版本、非有限数值、非法枚举、重复规则 ID、
+尺寸/数量上限、截断或尾随 payload，并在完整候选通过后一次交换。Version 0 作为旧格式迁移入口，
+其规则没有 enabled 字节，恢复时统一迁移为启用；version 0/1/2 均可恢复，再次保存会写为 version 3。
+
+### Probe 资源点
+
+`eve.generateTerrainProbes(output,fitness,heights,settings,type)` 导出 Pcg Probe 资源的拥有式 PointSet；
+type 为 0=Reflection、1=Light。`eve.TerrainProbePlacementSettings()` 提供 `name`、`originX`、
+`originZ`、`width`、`depth`、`heightScale`、`spacing`、`jitterPercent`、`minimumFitness`、
+`seaLevelActive`、`seaLevel`、`reflectionOffset`、`lightOffset`、`reflectionResolution`、
+`reflectionClipDistance`、`reflectionShadowDistance`、`seed`、`namespaceId` 和 `maxPoints`。
+
+扫描使用显式 Pcg XorshiftPlus 流。ReflectionProbe 在启用海平面时位于
+`max(terrainHeight,seaLevel)+reflectionOffset`；禁用时保留源码的 `500+seaLevel+0.2` 回退。
+LightProbe 仅在地形严格高于 seaLevel 时生成，并增加 lightOffset。输出携带稳定 ID、probe 类型、
+资源名、namespace、反射分辨率、裁剪距离和阴影距离；场景节点及实际反射捕获由 graphics/scene provider
+消费这些值，不由 procgen 保存。
+
+`TerrainSpawnPlan.addProbes(ruleId,fitness,settings,operation,mode,type)` 和
+`TerrainWorldWorkspace.applyProbes(...)` 将 Probe 纳入与其他生成域相同的跨 tile 事务；mode 为
+0=Add、1=Replace、2=Remove。Replace/Remove 只匹配操作窗口内相同 `probeResource` 的点，整次操作失败时
+所有 tile 保持原值。`copyProbes`、`clearSpawns`、undo/redo 和分步 SpawnPlan 都读写完整世界快照中的
+独立 Probe 状态。SpawnPlan version 3 持久化 Probe 类型、资源名、操作模式、fitness 与全部设置。
+
+`eve.publishTerrainProbes(batchId,points)` 通过可选 `IProcgenProbeSink` 将完整 PointSet 原子发布给 graphics。
+Reflection 点创建并注册拥有式 `ReflectionProbeCapture`，Light 点作为同批稳定光照采样位置保留；再次发布
+同一 batch 会先构造完整候选再替换。`removeTerrainProbeBatch` 销毁批次及捕获资源，
+`tickTerrainProbeBatches(faceBudget,filterBudget,filterSamples)` 按显式预算推进六面捕获和过滤。
+`getTerrainProbeBatchCount`、`getTerrainReflectionProbeCount`、`getTerrainLightProbeCount` 提供可观察状态；
+graphics provider 缺失时发布、删除和 tick 返回 `Unsupported`，查询返回零。
+
+### Biome Preset 生成栈
+
+`eve.TerrainBiomePreset()` 对应 Pcg `BiomePreset.m_spawnerPresetList`。`addSpawner(entryId,plan,
+activeInBiome,activeInStamper,autoAssignResources)` 按列表顺序深拷贝一个非空 Spawner 计划；entry ID
+必须稳定且唯一。两个 active 标志分别控制 biome controller 自动生成和 stamper 联动生成，
+`setActiveInBiome`、`setActiveInStamper` 按稳定 ID 修改。`getAutoAssignResources` 保留 Pcg
+`m_autoAssignPrototypes` 的资源准备意图，实际资源仍由各规则的稳定 namespace/asset 引用拥有。
+`getSpawnerCount()` 返回 preset 当前拥有的 Spawner 条目数。
+
+`TerrainWorldWorkspace.spawnBiome(preset)` 与 `spawnStamper(preset)` 只选择对应 scope 的条目，再按
+entry 顺序和内部 rule 顺序编译为一个计划。不同 Spawner 可复用局部 rule ID；编译时会用长度定界的
+entry ID 形成无歧义复合身份。整个栈仍只发布一个完整世界快照，因此跨 Spawner 的后置失败不会留下
+先前纹理或植被结果。没有对应 active 条目时返回结构化失败。
+
+长生成栈可用 `beginSpawn(plan)`、`beginSpawnBiome(preset)` 或 `beginSpawnStamper(preset)` 启动，再用
+`stepSpawn(maxRules)` 按正数规则预算推进。状态 0=Idle、1=Pending、2=Completed、3=Cancelled、4=Failed；
+`getSpawnStatus()` 和 `getSpawnCompletedRules()` 提供轮询。Pending 候选深拷贝完整世界及历史，规则执行
+产生的纹理、detail、tree、object 中间结果均不可通过 copy API 观察；最后一条规则成功后才形成一次
+历史提交。`cancelSpawn()` 或任意规则失败会丢弃完整候选。Pending 时 create、所有同步修改、undo/redo
+均返回结构化失败，避免无声替换或分叉候选；读取最后发布快照仍然可用。
+
+`snapshotJson()` 输出确定性的 `eve.procgen.terrain-biome-preset` schema version 1，包含有序条目、三个
+标志和每项完整的嵌套 SpawnPlan snapshot。`restoreJson(json)` 严格拒绝根或条目的未知字段、重复/空 ID、
+非法嵌套计划及尺寸上限，并在全部条目通过后一次交换。Version 0 没有 `autoAssignResources` 字段，迁移
+时采用 Pcg 原型自动准备的兼容默认值 true；再次保存写为 version 1。
+# Pcg PhotoMode 地形质量
+
+`PcgTerrainPhotoModeAuthority` 通过显式 `setAuthority(true)` 成为照片模式 Terrain 域的唯一所有者。它保存并验证 draw-instanced、detail density、detail distance、heightmap pixel error 与 basemap distance。`selectLod` 将当前 pixel-error 直接用于既有 screen-space-error 地形 LOD 选择；`textureTier` 在相机距离越过阈值时返回命名的 Basemap 材质级别。细节实例渲染器读取 `state()` 中的 density、distance 和 instancing 标志，使同一份状态驱动网格、材质与植被细节。撤销或析构会释放 capability listener。
+
+## GTS 地形网格切片
+
+`GtsMeshSplitResult` 保存 `splitGtsMesh(output,source,xSplits,zSplits,pivot)` 产生的行优先网格切片。
+切割数量表示平面数，因此列数和行数分别为 `xSplits+1`、`zSplits+1`。每个源三角形会真正沿 X/Z
+边界裁剪，交点同步插值位置、法线和 UV，跨越边界的三角形会进入相邻切片。
+
+`pivot` 为 0 时保留源坐标，1 使用每块的最小 X/Z，2 使用中心 X/Z。通过 `getColumnCount()`、
+`getRowCount()`、`getTileCount()` 查询布局，`getTileOffsetX(index)`、`getTileOffsetZ(index)` 返回恢复
+世界位置的偏移，`copyTileMesh(index)` 返回调用者拥有的独立 `ProcgenMeshBuild`。无效索引返回 null，
+无效拓扑、非有限顶点、越界索引及非法切分数通过 Result 报错，旧 output 保持不变。
+
+`simplifyGtsMesh(output,source,quality,options)` 提供 GTS 网格导出的确定性 QEM 简化核心。`quality` 是
+`[0,1]` 三角形比例；折叠同步更新位置、法线和 UV，移除退化三角形后压紧顶点，并保留三角形组。
+`GtsMeshSimplificationOptions.preserveBorderEdges` 可锁定开放边界，`preserveUvSeamEdges` 可锁定同位置但
+UV 不同的 seam，`preserveUvFoldoverEdges` 可锁定 smart-link 中位置及 UV 均相同的 foldover 顶点组，
+`preserveSurfaceCurvature` 将法线变化纳入折叠代价。迭代使用 `aggressiveness` 控制的 GTS 阈值逐步放宽；
+每次坍缩会检查受影响面的新旧法向点积并拒绝翻面。边界保护允许内点坍缩到边界端点，因此不会移动
+边界轮廓。输出和输入可为同一 MeshBuild；所有验证与候选简化完成后才替换输出。
+
+`buildDefaultGtsTerrainLods(output,source,xSplits,zSplits,pivot)` 把切片和逐级简化组合成 GTS 默认四层
+LOD：质量依次为 1、0.5、0.25、0.125，屏幕相对高度为 0.95、0.7、0.6、0.02。每一级以上一级
+结果为输入。`GtsTerrainLodSet` 拥有全部行优先 tile，通过布局查询、tile offset、
+`getLevelQuality(level)`、`getLevelTransitionHeight(level)` 以及 `copyLevelMesh(tile,level)` 供脚本消费；
+无效 mesh 索引返回 null。C++ 的
+`buildGtsTerrainLods` 还接受逐层独立的简化选项，并在整个结果成功前不发布部分层级。
+
+启用 `enableSmartLink` 时，简化器会按 `vertexLinkDistance` 连接重合的开放边界顶点。内部三角形分别保存
+几何拓扑索引与属性索引，因此绑定后的顶点共享 QEM 拓扑和坍缩位置，但仍输出各自的法线与 UV。
+重合顶点 UV 不同标记为 seam，UV 相同标记为 foldover；对应 preserve 选项会阻止该分类边被坍缩。
+
+运行时可用 `selectLevel(relativeHeight)` 按 GTS/Unity 的屏幕相对高度选择层级；低于最后一个 transition
+返回 -1 表示剔除，非法输入返回 -2。`getLevelSwitchDistance(level,worldDiameter,verticalFovDegrees)` 将
+同一阈值换算成 `Renderable3D.setMeshLod` 使用的相机距离，`selectLevelForCamera` 可直接按距离、包围体
+直径和垂直 FOV 选择。换算采用透视投影关系，因而不依赖固定分辨率。
+
+`GtsTerrainLodSet.snapshotJson()` 输出 `eve.procgen.gts-terrain-lod` version 2，完整包含布局、逐层质量、
+transition、全部简化选项、tile offset、位置/法线/UV/index 流和每个三角形的 group 名称。
+`restoreJson(json)` 严格拒绝未知字段、未来版本、尺寸超限、非有限数值、无效索引或不匹配的 stream，
+并只在所有 tile 和 level 解码成功后一次替换当前结果。
+
+`Procgen.configureGtsTerrainTileLods(lods,tile,renderable,graphics,worldDiameter,verticalFov,originX,originY,originZ)`
+先把指定非空 tile 的全部层级上传到同一 Graphics owner；全部成功后一次清空并配置 Renderable3D 的
+四层 LOD、三个切换距离、末级剔除距离和带 pivot offset 的世界位置。上传失败或参数无效时 renderable
+保持不变。上传 mesh 由 Graphics 持有，Renderable3D 只保存借用引用。
+
+`GtsTerrainLodRuntime.replace(lods,procgen,graphics,worldDiameter,verticalFov,originX,originY,originZ)` 为所有
+非空 tile 创建候选 Renderable3D；候选在完整配置前保持不可见，全部成功后才显示并销毁旧批。
+`getRenderable(tile)` 按原 row-major 槽位返回 ECS 借用实体，空 cell、无效或 stale 槽位返回 null；
+`getTileCount()` 和 `getRevision()` 查询已提交状态。`clear()` 销毁全部实体并返回销毁数量。
+`GtsTerrainLodRuntime.applyMaterial(material)` 把同一个 Graphics 所有的材质借用引用应用到当前所有存活
+tile，并返回实际更新数量；运行时不取得材质所有权。`planGtsTerrainLodAssets(output,lods,terrainName,
+meshFolder)` 生成确定性的导出清单。`GtsTerrainLodAssetPlan` 通过 `getEntryCount()`、`getTileIndex(index)`、
+`getLevelIndex(index)`、`getObjectName(index)`、`getMeshName(index)` 和 `getRelativePath(index)` 查询条目。
+对象名兼容 GTS 的 `<terrain> SubTile<tile>_LOD_<level>`，mesh 名兼容其无分隔 level 后缀；EVEngine
+清单路径使用 `<folder>/<mesh>.eve.mesh.json` 作为稳定的作者侧标识；它不是可直接加载的独立文件。
+`asset_procgen::prepareGtsTerrainLodPackage` 会把全部非空层实际编码为 `eve.mesh/3` definition 与 EVMESH/3
+bulk，并生成可交给 `buildEvaArchive`、AssetCooker 和 EvpackGraphicsLoader 的完整 `.eva` 候选包。非法名称、
+路径、数组、索引或预算不会发布部分候选。
+
+`GtsTerrainLodRuntime.replaceAndHideSource(lods,procgen,graphics,sourceTerrain,worldDiameter,verticalFov,
+originX,originY,originZ)` 在完整 LOD 批成功发布后隐藏源 Renderable3D，并记住它进入交接时的可见性。
+替换失败不会修改源或旧批；换用另一个源时先恢复前一源，`clear()` 和运行时析构也恢复当前源。
+源引用保存为 ECS generation handle，因此源先销毁时 `getSourceTerrain()` 返回 null，后续清理不会访问
+陈旧实体。受运行时管理的 LOD tile 不能同时作为源。
+
+`buildGtsTerrainBaseMesh(output,heightmap,saveResolution,sizeX,sizeY,sizeZ)` 完成 GTS 转换的高度场前置阶段。
+`saveResolution` 为 0=Full、1=Half、2=Quarter、3=Eighth、4=Sixteenth，对应 1/2/4/8/16 的源样本步长。
+输出覆盖完整 terrain 尺寸与 `[0,1]` UV，Y 为高度样本乘 `sizeY`；法线从实际导出三角形重新计算。
+高度场间隔不能被步长整除、样本非有限、尺寸非法或网格超预算时返回结构化错误，旧 output 保持不变。
+
+`buildDefaultGtsTerrainLodsFromHeightmap(output,heightmap,saveResolution,sizeX,sizeY,sizeZ,subTiles,pivot)`
+原子执行 Pcg 的完整默认转换链。`subTiles` 与 GTSProfile 一致，表示 X/Z 两轴各自的切割平面数，因此
+默认值 3 产生 4×4 个 row-major tile；允许范围为原编辑器的 0–5。任一基础网格、切片或顺序简化阶段
+失败都不替换旧 LOD set。
+
+`GtsTerrainMeshSettings` 对应原包的 `GTSMeshSettings`，默认保存 Full、4 个 LOD、
+`100/50/25/12.5` 百分比和 3 个 split。LOD count 限制为 1–4，质量允许编辑器同样的 0–100；最后一个
+激活 LOD 总使用 0.02 剔除阈值，因此 1/2/3/4 层配置分别得到正确的 GTS transition 序列。
+`snapshotJson/restoreJson` 使用严格的 `eve.procgen.gts-terrain-mesh-settings` version 1 schema，未知字段、
+非法范围或错误数组长度不会修改旧设置。`buildGtsTerrainLodsFromHeightmap(output,heightmap,settings,...)`
+直接消费这份配置。
+脚本用 `getSaveResolution/setSaveResolution`、`getLodCount/setLodCount`、`getSubTiles/setSubTiles`、
+`getLodQuality/setLodQuality` 和 `getLodTransitionHeight` 查询或修改各字段。
+
+### GTS 地形导出配置
+
+`GtsTerrainExportSettings` 对应原包的 `GTSExportTerrainSettings` 中源地形与 impostor 两组 LOD
+配置。`appendSourcePreset(mode,level,quality,transition)` 与
+`appendImpostorPreset(mode,level,quality,transition)` 中 mode 取 0=Impostor、1=LowPoly；它们精确应用
+原版 `SetLODToImpostorMode` / `SetLODToLowPolyMode` 的采样分辨率、纹理分辨率、锐边、烘焙方式、
+法线图、顶点色与材质策略。transition 必须按列表严格递减，quality 使用 `[0,1]`。
+`getSourceLodCount()` 和 `getImpostorLodCount()` 返回两组数量。
+
+`snapshotJson()` / `restoreJson(json)` 使用严格的
+`eve.procgen.gts-terrain-export-settings` version 3 schema，保存顶层工作流、每层所有可执行字段和 QEM 参数；未知字段、
+非法枚举、纹理分辨率、非递减阈值或尺寸超限会失败；version 1 自动迁移并采用原 Pcg 顶层默认值；version 2 的 OBJ 面格式迁移为 Triangles，恢复只在整个候选有效后提交。C++ 的
+`compileSourceLevels()` 将源导出记录直接编译成现有顺序 LOD 网格管线使用的设置。
+
+`buildGtsTerrainExportLodsFromHeightmap(output,heightmap,settings,sizeX,sizeY,sizeZ,subTiles,pivot)`
+使用 source LOD 第一项自己的 SaveResolution 构造基础网格，再按完整 source 列表逐级简化；设置中的
+分辨率不再只是持久化元数据。`buildGtsTerrainColliderMeshFromHeightmap(output,heightmap,settings,...)`
+使用 workflow 的独立 colliderResolution 和 colliderSimplifyQuality 生成 MeshCollider 三角网格；只有
+addTerrainCollider=true 且 colliderType=Mesh 时接受调用。两条入口都在最终候选完成后替换 output。
+
+`encodeGtsTerrainObj(heightmap,saveResolution,sizeX,sizeY,sizeZ,faceMode)` 返回确定性的 UTF-8 Wavefront
+OBJ 文本。faceMode 为 0=Triangles、1=Quads；坐标按原 Pcg 导出器写成
+`(-terrainZ,height,terrainX)`，`vt` 同样保持原版的 `(v,u)` 顺序和一基 face 索引。它使用固定经典 locale
+和足以往返 float 的精度，不依赖系统小数点设置。导出设置 version 3 保存 workflow 的 objFaceMode；
+version 2 迁移时采用原默认 Triangles。
+
+`encodeGtsMaskedTerrainObj(heightmap,maskmap,saveResolution,sizeX,sizeY,sizeZ,faceMode,threshold,invert)`
+复现 Pcg `MaskedTerrainMesh` 的 masked OBJ 路径。它以每个输出格左下角的归一化 mask 样本分类整格：
+低于 threshold 属于 outside，其余属于 inside；invert=false 输出 inside，true 输出 outside。原版默认调用
+threshold=0.2。maskmap 可以使用与 terrain 不同的尺寸，采样采用原版 `normalized * dimension` 双线性规则；
+输出继续使用原版的 X/Z 顶点去重、UV 缩放和逆时针面序。
+
+`bakeGtsTerrainVertexColors(output,source,bakedTexture,edgeMode,smoothingIterations,terrainSizeX,terrainSizeZ,linearize)`
+执行 Pcg `ProcessEdgesAndColorBaking`。Smooth 保留共享顶点并按世界 X/Z 采样；Sharp 为每个三角形角展开顶点、
+重算法线，并把三角形三个纹理样本的平均色写给整面。平滑迭代使用原版四邻域、边缘 clamp 算法；linearize
+显式对应 SRP OrthographicBake 的 `.linear` 分支。颜色是 `ProcgenMeshBuild` 的可选 RGBA 顶点流，可通过
+`hasVertexColors()` 和 `getColor(vertex,component)` 查询。裁剪、QEM、group copy、变换及 LOD version 2
+快照都会保留颜色；旧 version 1 LOD 快照仍可迁移读取。
+
+### Pcg Mask Map Export
+
+`combinePcgMaskMapChannels(output, red, green, blue, alpha, activeChannels)` 与 Pcg 的
+`PW_ChannelCombine.shader` 一致：四张输入图各自仅取 red 分量，按 RGBA bit mask 写入目标；未启用通道写 0，
+输入尺寸或 bit mask 非法时目标保持不变。`placePcgMaskMapTileInto(atlas, tile, x, y, width, height)` 使用
+像素中心双线性缩放并事务写入 atlas 矩形，对应 `OneCombinedTexture` 的逐 terrain 拼接。文件编码继续使用
+ImageData 既有 PNG/JPG/EXR 输出接口。
+
+### Pcg 通用 Mesh LOD Generator
+
+`PcgMeshLodProfile.appendLevel(transitionHeight, fadeWidth, quality, combineMeshes, combineSubMeshes)`
+按近到远加入最多四级配置；transition 必须严格递减，三个标量均使用 0..1 范围。
+`buildPcgMeshLods(output, sourceMesh, profile)` 为每一级从同一份原始 MeshBuild 独立执行简化，完整成功后
+才替换 `PcgMeshLodSet`。可用 `copyLevelMesh(index)` 取得拥有式副本，或用 `selectLevel`、
+`getSwitchDistance` 检查投影阈值。
+
+`procgen.configurePcgMeshLods(lods, renderable, graphics, worldDiameter, verticalFovDegrees)` 会先上传全部层，
+然后一次替换 Renderable3D 的 LOD 链并设置最远层裁剪距离。上传或参数校验失败时 renderable 保持原状。
+`profile.setFadePolicy(mode, animate, duration)` 保存 Unity `LODFadeMode`：0=None、1=SpeedTree、
+2=CrossFade。各级 `fadeWidth` 与全局策略会随 output 原子写入 Renderable3D。距离模式在切换点前按当前
+级距离区间乘 fadeWidth 生成互补权重；末级可渐隐到 cull。动画模式由
+`Renderable3D.advanceMeshLodTransition(distance, dt)` 使用调用方注入的 dt 确定推进。
+
+`profile.setLevelRendererState(level, skinQuality, shadowMode, receiveShadows, motionMode,
+skinnedMotionVectors, lightProbeUsage, reflectionProbeUsage)` 保存 Pcg `LODLevel` 的逐级 renderer 策略。
+枚举数值与 Unity 一致，包括 `Bone4=4` 与 `CustomProvided=4`。`configurePcgMeshLods` 在所有 mesh 上传后
+把整条网格链和状态一次写入 Renderable3D；选中级别的 Off/On/ShadowsOnly、receive-shadow、Object/
+ForceNoMotion 和 reflection-probe Off 已进入主渲染路径。
+
+`PcgMeshLodBackup.capture(renderable)` 在替换前保存完整 MeshRenderer 状态以及实体 id/generation；
+`restore(renderable)` 仅对同一实体 generation 原子恢复并消费快照，错误目标不会改变自身或消费备份。
+原 mesh、parts、material 等资源仍由同一个 Graphics 实例拥有，Graphics 与这些资源必须比 backup 活得更久。
+`discard()` 可只丢弃备份。该对象对应 Pcg `LODBackupComponent` 与 `DestroyLODObject` 的恢复职责。
+脚本查询与矩阵接口为 `getAnimateCrossFading()`、`getCrossFadeAnimationDuration()`、`getFadeMode()`、
+`getFadeWidth(level)`、`getLevelRendererState(level,field)`、`getQuality(level)`、
+`getTransitionHeight(level)`、`getSourceCount()`、`getElement(row,column)`、`setElement(row,column,value)`；
+备份可用 `getEntityId()`、`getEntityGeneration()` 与 `isCaptured()` 检查身份和状态。
+
+`PcgMeshTransform` 保存 root-relative 4×4 row-major 矩阵；用
+`PcgMeshCombinePlan.appendSource(mesh, transform, defaultMaterialId)` 按 renderer 顺序复制输入。
+`combinePcgStaticMeshes(output, plan)` 依次变换顶点并按首次遇到的 material id 合并 triangle group；任一输入
+带颜色时，无颜色输入会补白色 RGBA。`buildPcgCombinedMeshLods(output, plan, profile)` 先组合一次，再让所有
+启用了 `combineMeshes` 的 level 从同一份组合结果独立简化。混合开启/关闭 combine 的 profile 会明确失败，
+避免生成与 Pcg renderer 拆分结构不一致的结果。两个入口都只在完整成功后替换 output。
+### Pcg Terrain Watcher
+
+`PcgTerrainWatcher` 将 Pcg 编辑器中基于 hierarchyChanged 的 Terrain 创建/删除检测改为
+显式、确定性的快照事务。调用 `beginScan()` 后按场景稳定顺序调用 `addTerrain(id)`，最后以
+`commitScan()` 原子发布；首次提交只建立缓存，不产生 Created 事件。
+`PcgTerrainWatcher.getTerrainCount()` 返回当前缓存规模；后续结果通过 `getChangeCount()`、
+`getChangeTerrainId(index)` 和 `getChangeType(index)` 读取，其中类型 0 为
+Created、1 为 Removed。新增项按本次扫描顺序排列，随后删除项按上次扫描顺序排列。
+`cancelScan()` 丢弃候选；重复/空 id 或错误调用顺序返回 Result 且不改变已发布集合。
+
+### Pcg Tree Manager
+
+`PcgTreeManager` 汇总多个地形生成出的世界空间树位置。先以 `reset(minX, minZ, width, depth)`
+建立 Pcg Quadtree 对应的半开世界边界，再用 `addTree(x, z, prototype)` 或
+`addTrees(pointSet, prototype)` 加入树；批量输入会完整校验后一次发布。
+`countInRange(x, z, range)` 与 Pcg 源码一致使用包含边界的轴对齐正方形查询，而不是圆形距离；
+`PcgTreeManager.getCount()` 返回当前总树数。管理器复制坐标与 prototype index，不保留 PointSet。
+
+### Pcg Biome Controller 自动加载边界
+
+`eve.PcgBiomeController()` 保存一个 biome 的世界位置、生成半径与 TerrainLoader 模式。`configure`
+使用 Pcg 原始公式计算 regular 立方边界：边长为 `range * 2 - 0.5`，用于避免范围恰好落在 tile
+边缘时加载多余相邻地形；正数 impostor range 直接加到该边长，零值关闭 impostor 边界。模式编号与
+原包一致：0 Disabled、1 EditorSelected、2 EditorAlways、3 RuntimeAlways。
+
+`fitToTerrain(minX, originY, minZ, sizeX, sizeY, sizeZ)` 使用单块地形 X/Z 中心、地形原点 Y 和 X
+半宽；`fitToAllTerrains` 使用聚合边界完整中心及 X 半宽。`tierAt` 返回 0 Regular、1 Impostor 或
+2 Unloaded，可直接驱动调用方的地形驻留调度。`getRange`、`getLoadMode`、`getRegularCenterX`、
+`getRegularCenterY`、`getRegularCenterZ`、`getRegularSize` 与 `getImpostorSize` 提供脚本侧状态读取。
+所有更新先验证完整候选，失败时保持旧边界。
+### Pcg Runtime Stamper
+
+`eve.PcgRuntimeStamper()` 移植 Pcg Pro `RuntimeStamper.cs` 的完整运行时编排。调用
+`configure(address, showGui, showDebug)` 后，由宿主资源系统加载高度图并传给
+`loadStamp(stamp, resourceName)`，再用 `execute(target, originX, originZ, spacingX, spacingZ)`
+执行清平、适配完整地形范围、应用高度 6、零旋转和中心到边缘的线性距离遮罩。执行采用候选副本，
+任一步骤失败都不会留下部分修改。资源路径会把反斜杠统一为 `/`；缺失资源可通过
+`reportMissingStamp()` 进入可观察的失败状态。`getUpdateTimeAllowed()` 固定返回 Pcg 原示例的
+`1/15` 秒预算，`updateLayout()` 保留 300x20 底部居中进度标签的位置语义。脚本可通过
+`getStatus`、`getStampAddress`、`getProgressText`、`getLabelCenterX` 与 `getLabelCenterY` 读取状态。
+
+#### 第二百一十九批：RuntimeStamper
+
+- 对照 `RuntimeStamper.cs` 保留资源地址默认值、路径归一化、加载/失败/完成状态与进度文本。
+- 将 `FlattenTerrain -> FitToTerrain -> height=6 -> linear distance mask -> rotation=0 -> Stamp`
+  组合为一次原子操作，同时复用 EVEngine 的 `Heightmap` 与 `applyTerrainStamp`。
+- 控制器拥有 stamp 副本，不跨帧保留调用方指针；无回调、无锁、无隐式时间或随机数。
+
+### Pcg Spawn Progress
+
+`eve.PcgSpawnProgress()` 保存跨 spawner 的规则进度。`updateRule` 设置名称、总规则计数和当前
+spawner 计数，`updateRuleFraction` 更新当前规则的小数进度；`getProgress` 使用
+`(totalCompleted + fraction) / totalCount`。`getTitle`、`getSubtitle`、`getStatus` 提供 UI 所需快照，
+`requestCancel` 发布取消请求，`clear` 隐藏并清空状态。所有更新先验证候选，非法计数或进度不修改旧值。
+## GridGraph、PointGraph 与 MeshGraph 混合编排
+
+`GridGraph` 是面向语义格子的确定性数据流图。内建掩码生成节点覆盖填充、随机噪声、棋盘、点阵、
+形状、元胞自动机、随机游走、迷宫和 Poisson 撒点；`generate.registry` 则直接复用现有
+`GeneratorRegistry`，以 `algorithm` 字符串选择 `dungeon.bsp`、`level.roguelike`、WFC 等成熟
+生成器，并把节点上的整数、浮点和字符串参数投影为 `Params`。地牢算法只保留注册表中的一份实现。
+修改与选择节点覆盖布尔组合、反转、膨胀、收缩、平滑、随机/边缘/邻居/规则/岛屿/岛心/
+细节范围/语义选择、寻路与八邻域 autotile。固定 seed 的生成结果可复现。
+
+`convert.grid_to_points` 是显式的类型边界：它将匹配语义的格子中心转换为 `PointSet`，并写入
+`cell_x`、`cell_y`、`semantic` 和 `detail` 属性。`point.subgraph` 随后可把这组点送入独立的
+`PointGraph`，用于筛选、变换、采样和组合。
+
+`MeshGraph` 接受 `Grid2D`、`PointSet` 与 `MeshBuild` 三种强类型输入。`mesh.grid_tiles` 从格子
+构造顶面和暴露侧墙，并按
+`group/semantic/tile-kind/rN/(normal|mx)/reference-configuration` 建立命名三角形组。
+其中标准网格 mask 会映射到 TileWorldCreator 4.3.5 的 3×3 配置表，直接携带瓦片类别、
+0/90/180/270 度朝向和 X 镜像语义；原版未归类的配置 350 保持为 `none`。
+
+`eve.ProcgenObjectBuildLayer()` 是 Objects Build Layer 的原生对应物。它接收 PointGraph 产生的
+`PointSet`，按稳定点身份和层 seed 确定性选择加权 `asset`，并应用层偏移、位置散布、Euler
+旋转、统一或非统一缩放。`setOrientation` 可按北、东、南、西优先级朝向另一点层；
+`setPlaceOnTop` 读取输入点的 `surface_highest_y` 或 `surface_lowest_y`。`addChild` 生成带
+`object_role=child` 与 `parent_index` 的子对象点。结果仍是普通 PointSet，可继续送入 PointGraph、
+`mesh.instance_points` 或实例发布接口。
+
+对象层 API 速查：`clearAssets` 清空加权资产；`setLayerOffset`、`setLayerScale` 设置层级变换；
+`setPositionRadius` 设置平面散布半径；`setRandomRotation`、`setRandomScale` 设置确定性随机范围；
+`disableOrientation` 关闭朝向层；`clearChildRules` 清空子对象规则；`buildOriented` 使用显式朝向点集
+执行对象层。GridGraph 与 MeshGraph 的运行时输入分别通过 `setNodeGrid` 绑定；GridGraph 使用
+`setNodePointSubgraph` 绑定拥有明确输入/输出节点的 PointGraph 子图。
+
+`eve.ProcgenBuildLayerStack()` 将 Tiles 与 Objects 定义放进同一个有序执行器。`addTileLayer` 和
+`addObjectLayer` 保存值副本，`setEnabled` 控制参与执行的层；`execute` 只在全部启用层成功后返回
+`ProcgenBuildLayerExecution`，再通过 `getType/getMesh/getPoints` 获取具名 artifact。配置使用
+`EVPCG_BUILD_LAYERS 1`，对象层使用嵌入式 `EVPCG_OBJECT_LAYER 1`；反序列化拒绝未知记录和尾随字段，
+并在完整校验成功后原子替换旧配置。
+
+层栈可用 `getLayerId`、`getLayerType` 和 `isLayerEnabled` 查询定义；`executeOriented` 为需要朝向
+点集的对象层执行完整栈。增量执行器的 `getCachedClusterCount` 返回当前成功提交的活动簇数量，
+失败构建不会改变该计数。
+
+`eve.ProcgenIncrementalBuildExecutor()` 为 BuildLayerStack 增加跨次构建缓存。`update` 接收簇边长（格子数）
+和格子世界尺寸，返回 `ProcgenIncrementalBuildDelta`；每项通过 `getClusterX/getClusterZ/isRemoved` 标识
+场景侧应更新或删除的簇，非删除项用 `getArtifacts` 取得该簇的完整层结果。格子哈希带一格 halo，
+因此边界 autotile 改动会同时使相邻簇失效；点按半开世界坐标范围归属一个簇。任一脏簇构建失败时，
+内部旧缓存不变。带朝向层时使用 `updateOriented`；`getCachedArtifacts` 可按簇坐标读取当前快照。
+场景侧应以 `clusterX:clusterZ` 作为派生缓存键：普通 delta 替换该簇的渲染/碰撞 artifact，removed
+delta 先从场景隐藏或移除旧对象再删除缓存项。空 PointSet 是合法簇结果，不应尝试上传空实例网格。
+示例中的物理消费者按同一键维护静态三角网格刚体：先成功创建替换体再销毁旧体，避免失败时留下
+无碰撞窗口；裁剪掉 `physics` 模块时明确退化为纯渲染路径，不影响生成结果与缓存权威状态。
+`mesh.instance_points` 把任意 `MeshBuild` 实例化到点集；`mesh.merge` 与 `mesh.transform` 完成
+组合和变换。输出仍是现有 `MeshBuild`，可继续交给统一发布、碰撞、材质和场景生命周期。
+
+三个图各自拥有缓存，不共享跨帧可变裸指针。连接时检查端口类型，Grid 输出不能直接连到
+Point 或 Mesh 输入，必须经过显式转换或输入绑定。图拓扑、参数或输入变化会从修改点向下游
+失效缓存，相同输入重复执行会复用结果。
+
+脚本通过 `procgen.newGridGraph()` 与 `procgen.newMeshGraph()` 获取模块拥有的句柄；所有失败均为
+统一 Result 投影。两种图定义都支持版本化 `serializeDefinition()` / `deserializeDefinition()`；
+运行时输入值刻意不写入定义，加载后由调用方重新绑定，避免资产与场景实例形成第二份权威状态。

+## `.dnut` 剧情脚本（RPG 方言）
+
+`.dnut` 是引擎的作者序列语言。**RPG 方言**由 `rpg` 模块注册词表，用一份文本描述
+剧情事件的移动、动画、选取、技能、属性、物品与装备。语言核心（词法、编译、
+跨帧解释器）在 L1 模块 `dnut_interpreter`，RPG 只贡献**词表**与领域 handler。
+
+### 最小例子
+
+```
+story village.arrival {
+    move actor=hero x=10 y=4 duration=0.5
+    animation target=hero clip=emote.wave hold=true
+    skill actor=hero learn=fireball
+    attribute actor=hero name=attack op=add value=5
+    item add=potion count=2
+    equipment actor=hero equip=iron-sword slot=weapon
+    flag name=village.visited state=true
+    message text=Arrived
+}
+```
+
+### 步骤词表
+
+| 步骤 | 字段 | 形状 | 谁执行 |
+| --- | --- | --- | --- |
+| `move` | `actor` `x` `y` `[duration]` | 宿主呈现 / 移动控制器 | `RpgStoryBinding::moveActor`；未装控制器时由呈现层执行，脚本确认 |
+| `animation` | `target` `clip` `[loop]` `[hold]` | 宿主呈现 / 播放控制器 | `RpgStoryBinding::playAnimation`；未装控制器时由呈现层执行，脚本确认 |
+| `select` | `object` `[prompt]` | 宿主呈现 | 交互层 |
+| `camera` | `x` `y` `[duration]` | 宿主呈现 | 相机 |
+| `dialogue` | `id` | 宿主呈现 | dialogue 模块 |
+| `message` | `text` | 宿主呈现 | UI |
+| `skill` | `actor` + (`learn` \| `forget`) | 立即 | `RPGActor::learnSkill` / `forgetSkill` |
+| `attribute` | `actor` `name` `op(set\|add\|sub\|mul)` `value` | 立即 | `RPGActor` 基础属性 |
+| `item` | (`add` \| `remove`) `[count=1]` | 立即 | `inventory::Bag` |
+| `equipment` | `actor` + (`equip` `slot` \| `unequip`) | 立即 | `inventory::EquipmentSet` |
+| `flag` | `name` `state` | 立即 | `GameState` 开关 |
+| `variable` | `name` `op(set\|add)` `value` | 立即 | `GameState` 变量 |
+
+控制流：`if <条件> { … } else { … }`、`choice { option "标签" [when <条件>] { … } }`、
+`call <storyId>`、`wait <秒>`、`end`。
+
+条件是 `变量 运算符 字面量`，可用 `&&`、`||`、`!` 和括号组合。变量名用点号寻址
+`GameState`：`switch.<名>`、`variable.<名>`、`self.<scope>.<名>`。
+
+### 角色移动（跨游戏模式）
+
+`.dnut` 只声明「谁去哪里、用多久」，**不声明怎么走**。`x` / `y` 的含义由宿主定义：
+格子 RPG 当作格坐标，战棋当作棋盘格，连续世界当作世界单位，横版当作车道。引擎
+既不解释也不取整，更不假设任何寻路模型，所以同一份剧情脚本可以同时服务不同玩法。
+
+宿主在 binding 上装一个 `moveActor`，`move` 步骤就自动交给它，不必再在宿主循环里
+写 `if (kind == "move")` 分支：
+
+```cpp
+eve::rpg::RpgStoryBinding binding;
+binding.party     = &party;
+binding.gameState = &gameState;
+binding.moveActor = [](const eve::rpg::StoryMoveRequest& request) {
+    // 你的移动模型：格子 / 战棋 / 连续世界都在这里决定。
+    return navigator.request(request.actorId, request.x, request.y,
+                             request.hasDuration, request.duration);
+};
+```
+
+三种返回值决定剧情如何继续：
+
+| 返回值 | 效果 |
+| --- | --- |
+| `StoryMoveStatus::Arrived` | 步骤**立即完成**，剧情继续，不挂起（瞬移，或角色已在目标点） |
+| `StoryMoveStatus::Travelling` | 剧情挂起，宿主在角色**真正到达后**调用 `session.advance()` |
+| `StoryMoveStatus::Unreachable` | 步骤失败，返回结构化诊断，游标停在原地 |
+
+控制器返回失败 `Result` 时诊断原样上报，因此「寻路服务没加载」这类原因不会被吞掉。
+
+**不装控制器时行为完全不变**：`move` 仍是宿主呈现步骤，脚本读 payload 后 `advance()`。
+这是给「移动必须走自己的命令队列」这类宿主留的出口，也是既有内容的兼容路径。
+
+`StoryMoveRequest::actor` 只是便利投影：仅当 binding 能解析该 id（`party` 或
+`resolveActor`）时才非空。地图物件、相机、编队等非队伍主体会让它为 null，而步骤
+照样执行——用 `actorId` 在自己的主体空间里解析即可。
+
+### 动画播放（跨游戏模式）
+
+`.dnut` 只声明「谁播哪个 clip、要不要循环、结束后是否定格」，**不声明怎么播**。
+`clip` 对引擎是**不透明字符串**：骨骼动画 clip id、Sprite 序列名、Spine 动画、
+montage 段都可以。引擎既不解析也不加载它，更不假设任何骨骼或动画栈，所以同一份
+剧情脚本可以同时服务不同玩法。
+
+宿主在 binding 上装一个 `playAnimation`，`animation` 步骤就自动交给它，不必再在
+宿主循环里写 `if (kind == "animation")` 分支：
+
+```cpp
+eve::rpg::RpgStoryBinding binding;
+binding.party         = &party;
+binding.gameState     = &gameState;
+binding.playAnimation = [](const eve::rpg::StoryAnimationRequest& request) {
+    // 你的播放模型：骨骼 / Sprite / Spine / montage 都在这里决定。
+    return player.play(request.targetId, request.clip, request.loop, request.hold);
+};
+```
+
+三种返回值决定剧情如何继续：
+
+| 返回值 | 效果 |
+| --- | --- |
+| `StoryAnimationStatus::Finished` | 步骤**立即完成**，剧情继续，不挂起（瞬发、零长 clip、纯表现性闪烁） |
+| `StoryAnimationStatus::Playing` | 剧情挂起，宿主在 clip **真正播完后**调用 `session.advance()` |
+| `StoryAnimationStatus::Unavailable` | 步骤失败，返回「谁播不了哪个 clip」的结构化诊断，游标停在原地 |
+
+控制器返回失败 `Result` 时诊断原样上报，因此「clip 库还在流式加载」这类原因不会被吞掉。
+
+`loop` 与 `hold` 按作者书写的原样透传，引擎不解释：`loop` 表示无限重复，`hold` 表示
+clip 结束后停在最后一帧。宿主如果没有对应概念，忽略自己没实现的标志即可——省略这两个
+字段时它们都是 `false`，不会替宿主做任何猜测。
+
+**不装控制器时行为完全不变**：`animation` 仍是宿主呈现步骤，脚本读 payload 后
+`advance()`。这是给「播放必须走自己的状态机 / 混合调度」这类宿主留的出口。
+
+`StoryAnimationRequest::actor` 与移动的 `actor` 一样只是便利投影：仅当 binding 能解析
+该 id（`party` 或 `resolveActor`）时才非空。特效挂点、地图道具、UI 元素等非队伍主体会让
+它为 null，而步骤照样执行——用 `targetId` 在自己的主体空间里解析即可。
+
+### 使用
+
+下面的脚本走的是**未装 C++ 移动控制器**的宿主呈现路径：`move` 怎么做完全由脚本
+决定，这正是「脚本控制角色移动」的推荐写法，也是跨玩法最灵活的一条路。
+
+```squirrel
+local rpg = getModInst("rpg");
+rpg.replaceStoriesFromDnut(fileContent, "village.dnut");   // 严格校验 + 原子替换
+
+local session = rpg.newStorySession();
+local result  = session.begin("village.arrival", gs, party, bag, equipment);
+if (!result.ok) { print(result.status.summary + "\n"); return; }
+
+while (session.isActive()) {
+    local kind = session.getStepKind();
+    if (kind == "move") {
+        // 呈现层负责移动；完成后确认
+        moveActor(session.getStepString("actor"), session.getStepNumber("x"), session.getStepNumber("y"));
+        session.advance();
+    } else if (kind == "choice") {
+        session.select(session.getChoiceLabel(0));
+    } else if (kind == "message") {
+        showMessage(session.getStepString("text"));
+        session.advance();
+    } else {
+        session.advance();
+    }
+}
+```
+
+### 脚本面（Squirrel）
+
+`eve.rpg` 上的方法：
+
+| 方法 | 作用 |
+| --- | --- |
+| `replaceStoriesFromDnut` | 严格编译并原子替换 `.dnut` 故事目录 |
+| `clearStories` | 清空已发布的故事 |
+| `getStoryCount` | 已发布故事数量 |
+| `hasStory` | 某个 story id 是否存在 |
+| `newStorySession` | 新建一个 `RPGStorySession` |
+
+`RPGStorySession` 上的方法：
+
+| 方法 | 作用 |
+| --- | --- |
+| `begin` | 启动一个 story，运行到第一个挂起点；`party` / `bag` / `equipment` 可传 `null`（纯演出 story 不需要它们） |
+| `advance` | 确认当前宿主呈现的步骤并继续 |
+| `select` | 按标签回答 `choice` 步骤 |
+| `stop` | 停止并清空会话 |
+| `isActive` | 是否有 story 正在运行 |
+| `isBlocked` | 是否挂起等待确认 |
+| `getStoryId` | 当前 story id |
+| `getStepKind` | 当前步骤类型 |
+| `getChoiceLabelCount` | 当前 `choice` 的选项数 |
+| `getChoiceLabel` | 按序号取选项标签 |
+| `getStepString` | 取当前步骤的字符串字段 |
+| `getStepNumber` | 取当前步骤的数值字段 |
+| `getStepBool` | 取当前步骤的布尔字段 |
+
+### 语义要点
+
+- **严格编译**：字段名、字段类型、跨字段规则（`learn` 与 `forget` 恰有其一）在
+  `replaceStoriesFromDnut` 时报错；含错误的文档**不替换**上一份目录。
+- **宿主呈现的步骤**没有 C++ handler：运行时会挂起，脚本必须 `advance()`；
+  `choice` 必须用 `select(标签)` 回答，`advance()` 会被拒绝。
+  `move` 在装了移动控制器时由 handler 派发，但**确认方式相同**——角色到达后
+  调用 `advance()`；控制器返回 `Arrived` 时根本不会挂起。
+- **领域步骤**在运行时立即执行；失败（例如袋中不足）会让 `begin`/`advance` 返回
+  结构化失败并保持游标，不会静默跳过。
+- **完成事实**：不可重复的 story 完成后把 `story.<id>.completed` 写进 `GameState`，
+  再次 `begin` 会失败；`repeatable` story 每次重新开始。
+- **快照**：`begin` 时快照整份目录，热替换不会让活动会话悬空。
+

+PhotoMode 的 Photo 域由 `PcgPhotoModePhotoAuthority` 保存并统一发布。它覆盖场景身份、
+截图分辨率、EXR/JPG/PNG/TGA 格式、加载保存设置、关闭时恢复，以及 FPS、准星和三分法
+叠层开关。分辨率索引 0 使用当前 drawable 尺寸，1..9 精确映射 Pcg 的 640×480 到
+7680×4320 档位；`screenshotSize()` 与 `screenshotExtension()` 供捕获和 UI 调用方读取。
+authority 只保存稳定值，不持有 widget；实际叠层仍由 UIHost 使用现有 UI API 构建。
+
+### Pcg 截图按钮与颜色预览同步
+
+`AutoAssignTakePhotoEvent` 的启动期按钮接线使用现有 `ui.onClick(id, callback)`：回调中调用 `gfx.saveFramePng(path)`；首次启用 readback 后若尚无已呈现帧会返回 `false`，下一帧再次调用。该组合对应 Unity `Button.onClick -> ScreenShotter.TakeHiResShot`，并允许调用者显式选择输出路径。
+
+`eve.PcgColorPreviewSync()` 对应 `ColorPreviewSync.OnEnable`。调用 `sync(r,g,b,a)` 后，通过 `getRed()`、`getGreen()`、`getBlue()`、`getAlpha()` 取得按钮 highlighted color：纯黑源色映射到 `(0.5,0.5,0.5,1)`，其余颜色严格乘以原脚本硬编码的 `2.5`。非有限输入返回结构化错误且保留原状态。
+
+### PcgDraggableWindow
+
+`eve.PcgDraggableWindow()` 对应照片模式的 `DraggableUIWindow`。`configure(x,y,width,height,screenWidth,screenHeight,canvasScale)` 保存初始 anchored position；`drag(deltaX,deltaY)` 按 canvas scale 换算并复现 Pcg 的 X 负向、Y 正向边界钳制。`pointerDown(middleButtonDown)` 总是产生置顶请求，中键同时复位；用 `consumeBringToFront()` 消费请求，并通过 `getX()` / `getY()` 将结果交给 `ui.setHostPos`。
+
+### PcgPhotoModePanels
+
+`eve.PcgPhotoModePanels()` 保留七个 Pcg 照片模式页签的固定编号：Camera=0、Unity=1、Terrain=2、Lighting=3、Water=4、PostFX=5、PhotoMode=6。`select(panel)` 原子关闭其余六个面板并选择目标；`getSelected()`、`isActive(panel)`、`getRevision()` 提供快照，`consumeScrollReset()` 通知调用者重建 scroll content 并把滚动条置顶。
+
+`eve.PcgPhotoModePanelButton()` 通过 `configure(nonSelectedRGBA,selectedRGBA)` 保存两组颜色，`setSelected()` 同时控制按钮 normal/selected 色和面板布局开关。读取接口为 `getNormalR()`、`getNormalG()`、`getNormalB()`、`getNormalA()`、`getHighlightR()`、`getLayoutEnabled()`、`getSelected()`；highlight 始终来自选中色，与 Pcg 注册逻辑一致。
+
+### PcgPhotoModeColorPicker
+
+`eve.PcgPhotoModeColorPicker()` 实现照片模式颜色选择器。`open(r,g,b,a,hdr)`、`setLast(...)`、`setFocusedName(name)`、`close()` 管理打开、旧值和标题；`setRed()`、`setGreen()`、`setBlue()`、`setHdr()` 对应四条滑杆，`reset()` 恢复旧值。读取接口包括 `getRed/Green/Blue/Alpha`、`getPreviewRed/Green/Blue`、`getHdrSwatch()`、`getHdrEnabled()`、`getOpen()`、`getFocusedName()`、`getChangeRevision()` 和 `consumeBringToFront()`。HDR alpha 大于 1 或小于 0 时严格保留 Pcg 打开阶段和预览阶段的两次 RGB 乘法。
+预览通道的完整方法名为 `getPreviewRed()`、`getPreviewGreen()`、`getPreviewBlue()`。
+
+### PcgScreenshotSavedNotice
+
+`eve.PcgScreenshotSavedNotice()` 对应截图保存提示。`configure(enabled,showSeconds)` 设置开关和持续时间；截图成功后调用 `request(path)`，在该帧渲染结束调用 `endFrame(unscaledNow)` 才显示，再用 `tick(unscaledNow)` 到期隐藏。`getVisible()`、`getPathVisible()`、`getPath()`、`getPending()` 返回 UI 快照。重复 request 会取消旧显示并从新的 end-of-frame 重新计时。
+
+### PcgTooltipManager
+
+`eve.PcgTooltipManager()` 合并移植 Tooltip、TooltipManager、TooltipProfile 和 TooltipTrigger。`configure(interactionMode,theme,delay,bottomOffset,topOffset,wrapLimit)` 中 interactionMode 为 UI=0、SceneObjects=1、Both=2，theme 为 Light=0、Dark=1。`addTooltip()`、`removeTooltip()` 管理 profile；`enter(source,id,now)` 做 Pcg 的首个 substring 匹配，`enterText(source,content,header,now)` 对应 Trigger 自带文本，`exit(source)`、`hide()` 和 `tick(now,mouseX,mouseY,screenWidth,screenHeight,anyInput)` 管理延迟、位置与隐藏。
+
+状态通过 `getVisible()`、`getPending()`、`getHeader()`、`getText()`、`getHeaderVisible()`、`getWrapEnabled()`、`getPivotX()`、`getPivotY()`、`getBackgroundR()`、`getForeground()`、`getCount()` 读取。
+
+### PcgControllerSelection
+
+`eve.PcgControllerSelection()` 对应 `UIControllerSelection`。用 `add(name,controllerType,widgetId)` 按 Inspector 顺序登记说明项，`refresh(currentController)` 选择第一个类型匹配项并生成互斥可见快照；没有匹配时返回成功但 value=false，保留之前状态。通过 `getCount()`、`getSelectedIndex()`、`getVisible(index)`、`getWidgetId(index)` 读取，再用 `ui.setVisible` 应用到稳定 widget id。
+
+### PcgPhotoModeRuntimeUI
+
+`eve.PcgPhotoModeRuntimeUI()` 对应 `PhotoModeUtils` 与 `PhotoModeUIHelper` 的运行时控件状态。`configure(kind,name,value,current,min,max,imageFound)` 的 kind 从 Field=0 到 Vector3=13。各 `get*Visible()` 返回原 prefab 的互斥可见快照，`getInitialCallbackRevision()` 记录配置后主动派发初值的次数。
+
+### PcgLoadingScreen
+
+`eve.PcgLoadingScreen()` 接收 TerrainLoader 的四类加载事件。`configure(fadeOutSpeed)` 设置背景每秒
+衰减的 alpha；`onLoadProgressStarted()` 显示画布并把背景和进度复位，
+`onLoadProgressUpdated(progress)` 更新进度且在值达到 1 时自动执行 `onLoadProgressEnded()`。
+结束会隐藏进度条和文本并开始淡出，调用方每帧用 `tick(deltaTime)` 推进；alpha 到零后画布关闭。
+
+超时诊断使用 `beginTimeout()` 开始事务，`addMissingScene(terrainName,impostorName)` 返回索引，随后用
+`addRegularReference(index,name)` 和 `addImpostorReference(index,name)` 收集仍引用该场景的对象，最后
+`endTimeout()` 原子发布与 Pcg 相同结构的诊断并开始淡出。`getCanvasVisible`、`getProgressVisible`、
+`getTextVisible`、`getFading`、`getProgress`、`getBackgroundAlpha` 和 `getTimeoutMessage` 返回 UI 快照。
+
+`markSliderUsed()`、`setSliderValue()`、`applyFloatInput()` 保留滑杆与文本框同步规则；`updateWrap(text)` 复现 68 字符 metrics 换行，包括无空格硬切时跳过切点字符的原始行为。
+
+状态查询包括 `getKind()`、`getName()`、`getValueText()`、`getValue()`、`getMinimum()`、`getMaximum()`、
+`getWholeNumbers()`、`getUsingSlider()`、`getInputRefresh()`、`getLabelVisible()`、
+`getSecondLabelVisible()`、`getSliderVisible()`、`getInputVisible()`、`getToggleVisible()`、
+`getButtonVisible()`、`getDropdownVisible()`、`getImageVisible()`、`getHeaderVisible()`、`getColorVisible()`、
+`getVector2Visible()`、`getVector3Visible()` 和 `getInitialCallbackRevision()`。
+
+### PcgPhotoModeValues
+
+`eve.PcgPhotoModeValues()` 完整保存 Pcg `PhotoModeValues` 的 102 个字段及原始默认值。字段名沿用 `m_*` 配置名；`getFieldCount/getFieldName/getFieldType` 提供稳定 schema，类型编号为 Bool=0、Int=1、Float=2、String=3、Color=4。使用对应 `setBool/setInt/setFloat/setString/setColor` 与 `getBool/getInt/getFloat/getString`；颜色先 `selectColor(name)`，再读取 RGBA。`resetDefaults()` 原子恢复原始配置。
+
+`snapshotJson()` 输出 `eve.ui.pcg-photo-mode-values` schema version 1，并包含全部 102 字段；`restoreJson(json)` 要求精确 schema、版本和字段集合，拒绝未知或缺失字段，解析到临时候选对象后一次性交换，因此任何错误都保留当前配置。
+
+### PcgPhotoModeSession
+
+`eve.PcgPhotoModeSession()` 对应 `PhotoMode.cs` 的进入、加载和退出事务。`begin(capturedJson,savedJson,loadSaved,savedEver,currentPipeline,savedPipeline,sceneName,lightingProfile)` 保存进入前快照，仅在管线、场景和光照配置均匹配时加载保存值。`getLoadDecision()` 返回 Current=0、Saved=1、SaveCurrent=2。`replaceWorkingJson()` 原子更新运行值；`end(resetOnDisable,applicationPlaying)` 选择工作值或进入前快照作为 `outputJson()`。
+
+退出后 `getRemovePhotoCameraRequested()` 和 `getUnfreezePlayerRequested()` 始终为真；只有两个退出参数均为真时 `getRestoreRequested()` 为真。调用者按这些请求恢复各权威模块并清理临时对象。
+
+脚本方法：`begin()`、`replaceWorkingJson()`、`end()`、`workingJson()`、`outputJson()`、`getActive()`、`getRestoreRequested()`、`getRemovePhotoCameraRequested()`、`getUnfreezePlayerRequested()`、`getLoadDecision()`、`getRevision()`。
+
+### PcgPhotoModeRanges
+
+`eve.PcgPhotoModeRanges()` 完整保存 `PhotoModeMinAndMaxValues` 的 57 组范围。`getCount/getName` 按原声明顺序枚举；`select(name)` 后用 `getMinimum/getMaximum/getIntegral` 读取。`setRange()` 原子替换自定义范围，整数范围要求整数端点；`clamp(name,value)` 返回钳制结果。`m_densityVolumeFogDistance` 的默认上限保留正无穷。
+
+### Pcg PhotoMode 跨域应用事务
+
+PcgPhotoModeApplyPlan 比较两个完整 PcgPhotoModeValues 快照，按 Pcg 源字段声明顺序输出变更，并把字段路由到 Photo、System、Graphics、Camera、Streaming、Weather、Lighting、Water、PostFx、Terrain、Grass 或 Audio 权威域。executeRegistered() 通过 eve.photo-mode.apply capability 同步执行；未安装提供者会返回可观察的 Unsupported 错误。任一字段失败时，先前字段按逆序恢复，getRollbackComplete() 报告恢复是否完整。脚本可用 compileJson、命令枚举和执行状态来驱动照片模式。
+
+脚本方法：compileJson、executeRegistered、getCommandCount、getCommandField、getCommandDomain、getAppliedCount、getRollbackComplete、getRevision。
+
+照片模式注册执行器会把 m_globalVolume 通过现有 IAudioQuery 写入真实 Audio master volume。其他字段由实现 IPhotoModeFieldSink 的模块 listener 接收；每个字段必须恰有一个提供者，缺失或重复所有者都会使事务失败并触发逆序回滚。
+
+### Pcg Lighting profile 身份
+
+PhotoMode 的 `m_isUsingPcgLighting` 与 `m_selectedPcgLightingProfile` 由 `PcgPhotoModePhotoAuthority` 作为持久化身份联合保存。`lightingProfileMatches(currentProfile)` 同时比较 profile 索引和 Pcg/custom 模式；`PcgPhotoModeSession.begin()` 也使用这两个条件与场景名、渲染管线共同决定是否允许加载旧设置。

+# Autotile Production — 岸线、墙体与瀑布的自动拼接生产示例
+
+本示例在不使用任何美术资源的前提下，用 `map.newLayer` 建立三层瓦片层，分别演示岸线、
+墙体与瀑布三类自动拼接（autotile family）语义。它同时覆盖邻接掩码规则登记、矩形批量
+绘制与擦除、以及循环瓦片动画，可作为自动拼接落地到关卡数据前的最小生产参考。
+
+## 运行
+
+```bash
+make run/<platform>-debug GAME=examples/autotile-production
+```
+
+也可以进入示例目录后直接启动引擎：
+
+```bash
+cd examples/autotile-production && ../../build/linux-debug/src/engine/eve run
+```
+
+Windows 下引擎可执行文件为 `build/win32-debug/src/engine/eve.exe`。
+
+## 演示内容
+
+- 初始化：`eve_init` 先调 `gfx.setBackgroundColor(0.04, 0.06, 0.09, 1.0)`，再在
+  `map == null` 时创建 `eve.Map()`；三层分别由 `persist` 变量 `shore`、`walls`、
+  `falls` 持有，已存在时不会重复建立。
+- 岸线层：`map.newLayer(14, 10, 32.0, 32.0)` 建出 14×10、32 像素瓦片的层并
+  `setOrigin(32.0, 48.0)` 定位；`defineAutotileFamily(1, "shore", 1337)` 注册地形 1，
+  随后用 `mask` 从 0 到 255 的循环为全部邻接掩码各登记一条规则
+  `setAutotileRule(1 + mask % 12, 1, mask, 1)`（gid 在 1–12 之间循环复用）。
+- 矩形批量编辑：`paintTerrainRect(1, 1, 9, 7, 1)` 一次铺满整块地形，再用
+  `eraseTerrainRect(7, 1, 3, 2)` 与 `eraseTerrainRect(1, 6, 2, 2)` 各挖一个缺口，
+  让岸线掩码随邻接关系变化。
+- 墙体层：`map.newLayer(8, 10, 32.0, 32.0)`、`setOrigin(520.0, 48.0)` 与
+  `defineAutotileFamily(2, "wall", 7)` 之后，按掩码分别绑定顶部（gid 21 / 掩码 32）、
+  墙体主体（gid 22 / 掩码 34）与墙脚（gid 23 / 掩码 2），两段 `paintTerrainRect`
+  画出高度不同的两堵墙。
+- 瀑布层：`map.newLayer(6, 10, 32.0, 32.0)`、`setOrigin(720.0, 48.0)` 与
+  `defineAutotileFamily(3, "waterfall", 11)` 绑定水唇（掩码 32）、循环主体（掩码 34）
+  和溅落 / 墙脚（掩码 2）；再用 `addTileAnimationFrame(32, 32, 140)`、
+  `addTileAnimationFrame(32, 34, 140)`、`addTileAnimationFrame(32, 35, 140)` 让主体
+  瓦片以 140 毫秒换帧循环播放。
+- 每帧驱动：`eve_update(dt)` 调用 `map.update(dt)` 推进瓦片动画，`eve_render` 依次
+  调用 `gfx.clear()` 与 `map.render(gfx)` 重绘三层。
+
+## 操作
+
+`main.nut` 不轮询任何键盘或鼠标输入，示例里没有任何按键或鼠标绑定：三层地形与全部
+自动拼接规则都在 `eve_init` 中一次性建立，运行时只按帧推进动画与重绘。
+
+## 相关文件
+
+- `main.nut`：示例全部逻辑——三层创建、family 与邻接掩码规则登记、矩形绘制 / 擦除、
+  瓦片动画，以及 `eve_update` / `eve_render` 的每帧更新与渲染。
+- `config.nut`：窗口配置，标题为 `EVEngine Autotile Production`，尺寸 960×540，
+  `debug = false`。

 This example composes EVEngine's UI-neutral editor SDK into a project-specific
 combat action editor. It uses the canonical `eve.action.timeline` asset model,
 native hit testing and drag preview, one-step transactions, undo/redo, and
-deterministic preview events. The 3D viewport is driven by the same preview

+deterministic preview events. Its document toolbar opens two independently
+persisted montage assets, projects dirty state into tabs, and protects unsaved

 Controls:
 
-- Click **Melee 1H Attack Chop** to select and replay the authored action.
-- **Play / Pause** and **Restart** control deterministic action preview; Space
+- Switch between **Light Attack** and **Follow-up** document tabs. An asterisk
+  marks unsaved edits; closing a dirty tab requires a second explicit click to
+  discard its changes.
+- The save icon or Ctrl+S atomically writes the active document under
+  `Content/Actions`, validates it, and registers its stable GUID sidecar with
+  AssetDB. **Open Asset** provides a searchable picker over indexed, validated
+  Montage documents; selecting an already-open GUID activates its existing tab.
+- The compact transport icons control deterministic action preview; Space
   toggles playback.
 - Click empty timeline space to seek.
+- Timeline blocks project registry display names, compact resource/parameter
+  details and stable semantic mini-previews for VFX, audio, prefabs, cameras,
+  hitboxes, defense, input and movement. These visuals are derived UI state and
+  never become duplicate fields in the action asset.
 - Drag an item body to move it; drag a state edge to resize it.
-- Edit the selected hitbox start/end in the inspector sliders.
+- Selecting an animation section, instant notify, or state window automatically
+  opens the **Action Block** inspector. Its timing sliders commit validated,
+  undoable transactions; the toolbar deletes the selected block and exposes the
+  same undo/redo history. Audio, VFX and Prefab blocks expose typed resource,
+  playback, lifecycle and shared spatial controls. VFX states can atomically
+  fit their block duration to the trimmed clip at 1.0x speed, or fit the clip
+  end to the current block duration. When the Particles provider is loaded,
+  **Use Asset Duration** reads the real finite emitter/lifetime data instead
+  of asking the author to copy a duration by hand. Audio additionally exposes
+  a random clip URI pool, deterministic pitch variation, spatial blend and
+  attenuation distances, and exit fade controls; the advanced payload JSON
+  remains available for extensions. Each typed edit merges only its fields,
+  preserves unknown payload data, validates the complete result through the
+  notify registry, and commits one undo step. Notify type and payload JSON are
+  also editable for advanced authoring; registered type, Instant/State shape and
+  typed payload contracts are validated before the document changes. **Enabled** persists in schema v4;
+  disabled blocks remain visible and editable but do not emit preview/runtime
+  events. **New Block** opens a compact registry-backed picker for the target
+  track, Instant/State type, duration and payload; valid starter payloads make
+  every built-in type immediately insertable at the playhead. Copy/paste uses
+  the native deep-copy clipboard and pastes relative to the current playhead.
+  Ctrl/Shift-click adds blocks to the selection; the inspector reports the
+  complete selection range and aligns starts or ends. Dragging one selected
+  body moves the whole selection, while copy and delete operate on every
+  selected block in one undoable transaction.
+  Dragging also uses an eight-pixel magnetic threshold to snap against the
+  playhead, physical splits, animation-section edges and other block edges,
+  after applying the deterministic frame grid.
+  The **Track** tab selects and renames tracks, toggles mute/lock state, creates
+  all eight semantic track kinds, deletes tracks, and deep-copies whole tracks
+  across the open document tabs.
+  Selecting an animation section reveals its source URI, exact start/end,
+  blend-in duration, source trim range and blend curve. **New Section** creates
+  validated sections at explicit timeline ranges. Persisted UI state is migrated
+  when newer editor controls are introduced, preserving open document state.
+  The **Montage** tab edits play rate, looping, Foot IK, animation layer,
+  default blend windows and Root Motion masks. Valid changes update both the
+  persisted timeline and the already prepared runtime preview. Its Physical
+  Sections controls add a split at the live playhead, move an indexed split or
+  delete it; every operation preserves strict ordering and participates in the
+  same undo/redo history used by section jumps and adaptive time warping.
+  The **Joint** tab retains skeleton
+  transform and key editing in the same compact side panel.
+- The Presentation lane includes a cubic master-volume parameter curve. Its
+  sampled shape is drawn inside the block; native inspector/script APIs edit
+  its keys through the same undoable timeline transaction.
+- The impact camera cue drives the preview's real `CameraController` with a
+  deterministic position, rotation and FOV impulse.
 - **Undo / Redo** (or Ctrl+Z / Ctrl+Y) operates on the native timeline
   transaction history.
+- Use the transport speed controls or `Q` / `E` / `R` for 0.5x / 1.0x / 1.5x
+  playback. The HUD shows the authoritative physical section, section progress,
+  mixer weight and current rate.
 - Hold the right mouse button over the preview to orbit; use the mouse wheel to
   zoom.
+- Use WASD to move the player through `CombatLocomotionRuntime`. When playback
+  crosses the damage notify, target health and reaction update above the
+  viewport. Editing that block changes the next hit without a demo-only damage
+  model.
+The active editor snapshot is also registered as an `AbilityDefinition`; its
+physical sections become action phases, and the preview HUD reports the native
+Ability phase and cooldown instead of maintaining script timers.
+The skinned KayKit character consumes the Montage runtime pose directly, so
+section cross-fades, jumps and blend-out are visible on the real skeleton.
+Joint/key edits deep-copy the rebuilt clip into the running Montage and resample
+the current cursor without retaining editor-owned clip pointers.
+Saving hot-reloads that definition without revoking its grant. Press `J` while
+the authored `input:combo-window` is open to resolve its gameplay tag through
+`matchingAbilities`, replace the active exclusive Ability, and replay the
+montage through the fixed dual-slot coordinator. The outgoing execution keeps
+its clip snapshot and fades out while the replacement fades in, so combo
+transitions remain continuous. Input outside the authored window is rejected.
+Naturally completed montages retain their final weighted pose until another
+montage cross-fades it out, avoiding a one-frame snap back to the bind pose.
 
 The preview and timeline headers show the current selection, playback state,
 edit revision and the last emitted event so every interaction has visible

+# Composable Rebellion — 引擎只存事实、玩法语义全在脚本的叛乱示例
+
+本示例演示"通用能力 + 项目语义"的分层：引擎侧的 `eve.*` 模块只保存中性的属性、
+归属、授权、指令、事件等事实，完全不认识"忠诚""叛乱"这类领域概念。全部政治含义
+写在 `simulation.nut` 里，由一次拖欠军饷的薪资事件推动将领带着基地与军队倒向边疆阵营。
+
+## 运行
+
+```bash
+make run/<platform>-debug GAME=examples/composable-rebellion
+```
+
+也可以进入示例目录直接启动引擎：
+
+```bash
+cd examples/composable-rebellion && ../../build/linux-debug/src/engine/eve run
+```
+
+Windows 下可执行文件为 `build/win32-debug/src/engine/eve.exe`。
+
+## 演示内容
+
+- 模块装配：`reset_demo` 创建 `eve.Attributes`、`eve.Social`、`eve.Orders`、`eve.Tags`、`eve.Effects`、
+  `eve.GameEvent`、`eve.Transaction`、`eve.StatePatch`、`eve.Definitions`、`eve.Authority`、`eve.Production`、
+  `eve.PolicyRegistryModule`、`eve.Sensing`、`eve.Steering`、`eve.Decision`——引擎侧没有叛乱专用类型。
+- 事实与授权：`setBase` 写入 `administration` 80、`loyalty` 48、`ambition` 82 与 `production_speed` 1.0；
+  `setOwner` / `assign` / `setRelation` 建立 `general.arden`、`base.north`、`army.first` 的归属和
+  `officer.vela` 对将领的 `support` 关系；`Authority.grant` 授予 `govern_base` / `command_army`，
+  `PolicyRegistryModule.select` 在 `administration` 频道选中 `governor_bonus`。
+- 生产与 AI：`Production.setSlotCount` / `enqueue` 在同一基地混放 `build_unit`(`tank.medium`) 与
+  `issue_decree`(`decree.tax_reform`)，`advance` 按 `production_speed` 最终值推进；
+  `Sensing.circle` 查到最近敌军后交给 `Decision.setState` / `addTransition` / `trigger` / `choose`，
+  `Steering.arrive` 求朝向速度，`Decision.sample("threat", ...)` 采样 8×8 威胁网格。
+- 状态效果与判定：`Effects.apply` 施加 `salary_unpaid`，`addTag("politics")` 打标签、payload 写入
+  `loyalty_delta`，再用 `addModifier` 叠加 `loyalty` 负修正；`evaluate_rebellion` 按
+  `getFinal("loyalty")`、`ambition`、`relation(..., "support")` 三重阈值判定，并由
+  `Transaction.create` / `stage` / `markValid` / `validate` / `commit` 提交三步 `set_owner` 计划。
+- 原子切换与投影：`StatePatch.newBatch` + `setExpected(..., "faction.frontier", "faction.crown")`
+  校验后一次 `commit`，冲突则 `plan.fail("ownership_conflict")`；成功后 `Orders.newQueueOwned` /
+  `append` 下发 `secure_assets`，`GameEvent.append` 记录 `rebellion_started`，
+  `Social.setOwner` / `setRelation` 只作为查询投影同步。
+
+## 观察方式
+
+启动时 `eve_init` 调用 `run_rebellion_scenario()`，只打印一行
+`rebellion=... base_owner=... production=...`：`rebellion` 为 `true` 且 `base_owner` 为
+`faction.frontier`，说明事务提交与状态补丁都成功；`production` 不再是初始的 `1.0`，因为
+`refresh_governor_bonus` 用 `addModifier("governor.production", "production_speed", ...,`
+`"multiply", ...)` 挂了州长加成。任一步失败时会经 `decision_result_ok` 打印
+`decision <operation> failed: <status.summary>` 便于定位；`eve_render` 用 `gfx.drawSolidRect` 画
+左右两块，叛乱成功后左块（王权）红通道由 0.65 降至 0.18、右块（边疆）绿通道由 0.20 升至 0.72。
+
+## 相关文件
+
+- `main.nut`：入口——设置背景色、调用 `run_rebellion_scenario()`、打印结果并渲染两个色块。
+- `simulation.nut`：全部玩法逻辑——模块装配、生产与 AI、状态效果、叛乱事务与状态补丁。
+- `config.nut`：窗口 960×540、标题 `Composable Gameplay: Rebellion`、`debug` 与 `hotReload` 均为 `true`。
+- `README.md`：本说明。

+# Economy — 采集循环与满仓浪费的 economy 模块演示
+
+`economy_demo.nut` 是一个**无窗口**的脚本演示，用来快速验证 `eve.Economy` 的资源账本、
+`eve.GatherNode` 矿点与 `eve.Collector` 采集者的最小闭环：不做渲染，纯逻辑跑完整条
+「接近 → 采集 → 满载 → 返回 → 卸货入账」链路并打印逐步事件。
+
+## 运行
+
+该目录没有项目级 `main.nut` / `config.nut`，用 `-r` 直接运行根脚本（在仓库根目录执行）：
+
+```bash
+# Windows
+build/win32-debug/src/engine/eve.exe run -r examples/economy/economy_demo.nut
+
+# Linux / macOS
+build/linux-debug/src/engine/eve run -r examples/economy/economy_demo.nut
+```
+
+## 演示内容
+
+- **场景 1 · SC2 式矿物采集**：注册 `minerals` 资源（储量 100、有限），创建一个双槽位
+  `eve.GatherNode`（储量 30）与两个 `eve.Collector`（A：载荷 5 / 速率 1 / 单程 2 tick，
+  B：载荷 3 / 速率 2 / 单程 3 tick），`assign()` 占槽后按 tick 推进到双方 `isIdle()`，
+  打印每个 `gather / deposit` 事件、往返次数、累计入账与矿点余量。
+- **场景 2 · 满仓浪费**：玩家持有上限 10、节点储量 25、载荷 5，第三次往返起超出上限的部分
+  计入 `waste` 事件，用于展示 `eco.getWasted()` 与 `eco.getCap()` 的语义。
+
+## 输出
+
+脚本是确定性的：同样参数下 `doneTick`、往返次数与余额完全一致。结尾会打印两个场景的
+余额 / 上限 / 浪费统计，例如：
+
+```
+  玩家1 矿物余额: ... / 上限 100, 浪费 0
+  矿点剩余: 0
+```

+# hex-planet
+
+The `hexmap` module's hex terrain, wrapped onto a sphere and viewed from orbit.
+
+This is the spherical counterpart of [`examples/hex-terrain-3d`](../hex-terrain-3d):
+the same module, the same `HexCellData` / `HexValues` / `HexFlags` cell records, the
+same `HexMetrics` geometry constants, the same `HexMeshData` container and the same
+`HexTerrainVertexCode` vertex encoding. What changes is the surface: an icosahedral
+(Goldberg) topology instead of a rectangular chunk grid, and a radial "up" instead of
+world Y.
+
+```
+make run/win32-debug GAME=examples/hex-planet        # Windows
+make run/linux-debug  GAME=examples/hex-planet       # Linux (headless: see AGENTS.md)
+```
+
+## What it looks like
+
+Orbit camera around a generated planet, with a hexagonal tessellation you can read at
+the limb and in the faceted coastlines. `hex-planet.png` in this directory is captured
+by the example itself after 90 frames. The default pose is static, so two runs agree to
+within the ImGui overlay: measured across two runs, **25 of 1,024,000 pixels differ**
+(the HUD), and the globe itself is identical.
+
+## Controls
+
+| Input | Action |
+|---|---|
+| LMB drag | orbit / pitch |
+| wheel | zoom |
+| `space` | toggle auto-spin |
+| `R` | new seed |
+| `[` `]` | subdivision level down / up |
+| `-` `=` | land share down / up |
+| `esc` | reset the view |
+| `F5` | save `hex-planet.png` |
+
+## How it is put together
+
+Everything geometric is C++; the script owns only the camera, the input mapping, the
+two renderables and the HUD.
+
+| Piece | Where | Role |
+|---|---|---|
+| `HexSphereTopology` | `src/modules/hexmap` | icosahedral cell graph: ids, neighbours, edge directions, corners |
+| `HexSphereMap` | `src/modules/hexmap` | editable sphere: cell records, radial elevation, picking, brushes, dirty cells |
+| `HexSphereMesh` | `src/modules/hexmap` | builds the terrain and ocean meshes of the whole sphere |
+| `HexSphereGenerator` | `src/modules/hexmap` | continents, sea level, biomes from 3D noise |
+| script bindings | `HexMapModule` | `hexmap.sphere*` |
+| this directory | — | orbit camera, renderables, HUD, shaders |
+
+### The four things that do not survive the change of surface
+
+1. **Edge count.** A cell has six edges, or five if it is one of the twelve pentagons.
+   Nothing iterates a fixed six directions, and there is no `opposite(direction)`
+   offset that works everywhere: the sphere map uses `directionOf(cell, other)`
+   throughout, because a hexagon–pentagon edge has no arithmetic opposite.
+2. **Edge ownership.** The planar builder relies on the chunk grid to emit each shared
+   boundary exactly once. A sphere has no chunk grid, so the lower cell id owns the
+   edge instead — still a total order over the same set of edges.
+3. **"Vertical" is radial.** Positions are a unit direction times a radius, and the
+   terrace interpolation of a slope moves along the *arc* by the horizontal step and
+   along the *radius* by the vertical one.
+4. **Shading has no horizon.** The planar terrain shader reads `vWorldPos.y` as
+   altitude, `vNormal.y` as up, projects detail noise into XZ and fades into distance
+   fog. On a sphere Y spans the whole planet, XZ collapses at the poles, the normal is
+   the radial direction, and there is no horizon to fade into. `hex_planet_terrain`
+   keeps the palette and the BRDF byte-for-byte and replaces only those four.
+
+### Notes for anyone editing the shaders
+
+The host applies its own Reinhard-style tonemap to this fragment stage's output — a
+debug shader emitting a constant `1.0` arrives in the frame buffer as `224/255`, i.e.
+`y = x / (x + 0.139)`. Both planet shaders invert that curve
+(`hostTonemapInverse`) so the palette they author is the sRGB that actually ships;
+without it every colour is silently compressed twice and cannot be tuned.
+
+The two fragment shaders are compiled to SPIR-V, because runtime GLSL compilation is
+unavailable on Windows:
+
+```sh
+glslc -o shaders/hex_planet_terrain.frag.spv shaders/hex_planet_terrain.frag
+glslc -o shaders/hex_planet_water.frag.spv   shaders/hex_planet_water.frag
+```
+
+## Relationship to the other hex examples
+
+| Example | Surface | Recipe / module | Camera |
+|---|---|---|---|
+| `hex-terrain-3d` | flat, chunked | `hexmap` (editable map) | orbiting a ground map |
+| `hex-planet` | spherical, one mesh | `hexmap` sphere backend | orbiting the globe |
+| `hex-terrain` | flat mesh | `mesh.hexterrain` (procgen) | ground level |
+
+## Known gaps
+
+- The ocean is a plain hexagonal cap per flooded cell: it has no shore shelf, no
+  refraction and no shoreline foam, and it does not cover beaches at sea level
+  (`waterLevel == elevation` is not flooded, matching the module's own rule). Sea ice
+  is a shading term on that cap, not separate geometry.
+- Cliffs are radial walls with no overhang or erosion detail.
+- The generator has no rivers, erosion or plate tectonics; the planar
+  `HexMapGenerator` did not carry over.
+- The sphere has no rivers, roads, walls, features, fog-of-war or units, and no save
+  format. The cell *flags* can be set, but there is no spherical geometry, search or
+  serialization behind them.

+# Hex Map 3D
+
+An interactive pointy-top 3D hex map: elevation terraces and cliffs, water,
+rivers, roads, walls and decorations, units with A* pathfinding, fog of war,
+procedural map generation, save/load, an orbit camera, mouse picking and a
+hex-shaped brush. It is a port of the Catlike Coding
+[Hex Map](https://catlikecoding.com/unity/hex-map/) reference project onto
+EVEngine's `hexmap` module.
+
+This directory is the module's interactive reference example. The separate
+[`hex-terrain`](../hex-terrain/README.md) example is unrelated: it is the
+asset-free `mesh.hexterrain` procgen recipe and it still ships unchanged.
+
+Everything geometric and everything the fog/units/pathfinding rules decide lives
+in C++ (`src/modules/hexmap`): the editable cell grid, its 5x5 chunk partition,
+the picking query, the per-chunk mesh builders (terrain, water, river, road, the
+fog overlay, walls and decorations), the search/visibility scratch, the unit
+registry, the save-payload codec and the procedural map generator. This example
+owns the camera, the input mapping, the brush tool, the per-chunk renderables, the
+unit markers and the HUD.
+
+Run with `make run/win32-debug GAME=examples/hex-terrain-3d` (Linux:
+`make run/linux-debug GAME=examples/hex-terrain-3d`).
+
+## Controls
+
+| Key / input | Action |
+|---|---|
+| `W` `A` `S` `D` (or arrows) | Pan the camera on the XZ plane |
+| `Q` / `E` | Rotate the camera |
+| Mouse wheel (or `Z` / `X`) | Zoom; the far end tracks the map extent |

+the reference editor. The module rejects uphill rivers, roads that climb more
+than one elevation step, and roads that cross a river mid-channel.
+
+## What is implemented
+
+- Pointy-top hex grid with the reference metrics (`outerRadius 10`,
+  `elevationStep 3`, `solidFactor 0.8`, `waterFactor 0.6`, two terraces per
+  slope, `chunkSize 5x5`).
+- Ground fans, blend strips between neighbours, terraced slopes and cliffs, and
+  the corner matrix that closes the triple junctions (7 cases).
+- Water surface with a shore band, river channels carved to the stream bed, and
+  road ribbons. The water is triangulated per direction like the reference: an
+  open-water wedge plus a bridge quad towards flooded neighbours, or a subdivided
+  four-triangle shore wedge plus a four-quad bank strip towards land — and that
+  strip stays **flat at the water height**, borrowing only the neighbour's solid
+  corner positions. Tilting it up to the bank reads as a bright band tracing every
+  hexagon edge, which is why the whole surface is now provably horizontal.
+- Deterministic per-cell XZ and height noise, so no texture assets are required.
+- Five terrain layers blended per vertex and shaded with GGX lighting, slope
+  rock, a snow line and moving cloud shade.
+- Fog of war: cells are counted per viewer, the first viewer latches a cell
+  *explored* one-way, and the overlay draws a hexagonal column over every cell
+  no viewer currently sees (dim for remembered ground, near black for ground
+  never seen). The column also carries a skirt so the cliff faces along a fog
+  boundary are covered.
+- Units on a hex grid: A* over the cell graph with roads, slopes, cliffs, walls,
+  water and other units as movers, a turn budget derived from the unit's speed,
+  and a Bezier walk whose vision follows the corridor it travels.
+- Save/load as a self-describing little-endian payload (grid + explored flags +
+  units) written through `eve.Filesystem()`; the payload is validated in full
+  before any observable state changes.
+- City/farm walls, wall towers and bridges generated as geometry (the reference
+  instantiates prefabs; EVEngine ships none). Walls follow the reference's
+  `wallLerp`/`wallThicknessOffset` construction, open a gate where a road crosses
+  the boundary, and fill the high side of a step with a wedge.
+- Urban, farm, plant and special decorations, picked exactly like the reference:
+  the three collections are each tested against a deterministic per-cell hash and
+  the lowest passing hash wins, with a special feature suppressing the ordinary
+  decoration of its cell.
+- A procedural map generator ported from the reference `MapGenerator`: seeded land
+  regions grown with jitter and occasional rises/sinks, coastal erosion towards a
+  land-percentage target, downhill rivers with lakes, a 40-cycle downwind moisture
+  transport, and the reference's temperature/moisture biome table with plant
+  levels. Generation is reproducible from a seed alone.
+- Orbit camera, ray picking with an iterative elevation refinement, a hex cursor
+  and an immediate-mode HUD.
+
+The example seeds a deterministic starter map (a two-step central plateau, a
+flooded basin, two rivers draining off the plateau, a road crossing the lowland
+and a walled district with gates where the road crosses its wall) plus three
+units, so every system is visible on the first frame. `M` replaces it with a
+procedurally generated map.
+
+## Camera
+
+`eve.Camera3D()` defaults to a `0.1 .. 100` clip range. That is smaller than a
+single map span once the grid passes a few chunks, so anything beyond 100 world
+units was silently clipped and the far half of the zoom range showed an empty
+frame. The example now derives the far plane from the map extent every frame and
+scales the far zoom distance with it (`ZOOM_FAR_MARGIN`), so the whole map always
+fits the view whatever the map size.
+
+## Shaders
+
+The five fragment shaders are shipped as SPIR-V next to their GLSL sources
+because runtime GLSL compilation is unavailable on Windows. The engine's
+built-in Mesh3D vertex stage already produces the varyings they consume, so no
+vertex stage is shipped. Regenerate them after editing a `.frag`:
+
+```sh
+glslc -fshader-stage=frag shaders/hex_map_terrain.frag -o shaders/hex_map_terrain.frag.spv
+glslc -fshader-stage=frag shaders/hex_map_water.frag   -o shaders/hex_map_water.frag.spv
+glslc -fshader-stage=frag shaders/hex_map_river.frag   -o shaders/hex_map_river.frag.spv
+glslc -fshader-stage=frag shaders/hex_map_road.frag    -o shaders/hex_map_road.frag.spv
+glslc -fshader-stage=frag shaders/hex_map_fog.frag     -o shaders/hex_map_fog.frag.spv
+glslc -fshader-stage=frag shaders/hex_map_feature.frag -o shaders/hex_map_feature.frag.spv
+```
+
+There are six stages but seven surface streams: `hex_map_feature` serves both the
+wall stream and the decoration stream, because a vertex's first texture coordinate
+already says which of the seven parts it belongs to
+(`0` wall, `1` tower, `2` bridge, `3` urban, `4` farm, `5` plant, `6` special).
+
+The terrain fragment stage decodes three terrain layers from the two available
+texture coordinates (`u = layerA + layerB*8 + layerC*64`,
+`v = weightB + weightC*16`); `HexMapMesh.h` documents that encoding as a
+compatibility bridge, not as the terrain data format. The fog stage reads its
+single coordinate as the shade (`0` explored-but-unseen, `1` never explored).
+
+## Not ported yet
+
+Waterfalls and estuaries, the reference's wall-tower *prefab* proportions, and
+the fog overlay's per-cell visibility blend (it is a two-shade
+remembered/unseen pair). The map generator's erosion takes the lowest cell from
+the shared search frontier where the reference erodes a uniformly random cell,
+and its temperature jitter uses a private value noise instead of the reference's
+noise texture sample. `docs/usr/modules/hexmap.md` lists the same boundary from
+the module side.
+
+`hex-map.png` is captured by the example itself after 90 frames.

+# Material Editor
+
+Project-composed material studio: a UE5-style Material Sphere sits in the center
+viewport while the right inspector edits a live `gfx.Material`. There is no fixed
+C++ material-editor window — the Squirrel host owns layout, widgets, and preview.
+
+Run:
+
+```sh
+# Linux (headless Cloud VM)
+export VK_ICD_FILENAMES=/usr/share/vulkan/icd.d/lvp_icd.json
+export ALSOFT_DRIVERS=null
+export XDG_RUNTIME_DIR=/tmp/xdg-runtime && mkdir -p "$XDG_RUNTIME_DIR" && chmod 700 "$XDG_RUNTIME_DIR"
+cd examples/material-editor && xvfb-run -a ../../build/linux-debug/src/engine/eve run
+
+# Windows
+make run/win32-debug GAME=examples/material-editor
+```
+
+## Layout
+
+- **Top** — material presets (Plastic / Rubber / Brushed / Chrome / Gold / Copper / Glass) and turntable pause
+- **Center** — embedded 3D viewport with the UE5 Material Sphere (`gfx.newMeshSphere(64, 32)`), studio IBL cubemap (so metallic presets stay readable), key/fill/rim lights, and a neutral shadow floor
+- **Right** — schema-aligned knobs mirroring `MaterialDocumentTarget`: shading model, tint, metallic, roughness, surface/blend mode, alpha cutoff, parallax, lighting and shadow flags, plus preview mesh switch (Sphere / Cube / Cylinder)
+
+## Controls
+
+- LMB drag in the viewport to orbit
+- Mouse wheel to zoom
+- Auto turntable (Pause spin in the toolbar)
+- Inspector edits apply immediately to the shared `Material` on the preview ball
+
+Metallic / chrome / gold need image-based lighting: ambient alone is scaled by `(1 - metallic)`. The example bakes a six-face studio sky via `gfx.newReflectionProbeCapture` and attaches it with `camera.setEnvMap`.
+
+## Files
+
+| File | Role |
+|---|---|
+| `config.nut` | Window title / size / hot reload |
+| `main.nut` | Workspace panels, UE5 sphere preview, live Material binding |
+| `material-editor.png` | Auto-captured frame after a few frames (`gfx.saveFramePng`) |
+
+Knobs write one authoritative `Material` attached via `Renderable3D.setMaterial`; legacy tint/metallic/roughness fields stay synchronized for paths that still read MeshRenderer state.

+# Mesh Impact Lab（网格冲击形变）
+
+把 Box3D 的**碰撞命中事件**接到网格形变会话上：飞行弹丸撞上静态目标，按命中点的法向
+冲量对目标网格做一次性塑性冲击，重建并重新上传网格后立刻可见。整个示例没有任何输入，
+启动即自动演示，用于验证“物理命中 → 网格损伤 → GPU 重新上传”这条链路。
+
+## 运行
+
+```bash
+cd examples/mesh-impact-lab
+../../build/linux-debug/src/engine/eve run
+```
+
+或：
+
+```bash
+make run/<platform>-debug GAME=examples/mesh-impact-lab
+```
+
+## 演示内容
+
+1. `prototype.cylinder1` 配方生成目标网格，再经 `mesh.subdivide` + `mesh.weld` 修饰图
+   加密（细分 2 级、焊接容差 `1e-4`），作为可形变的目标。
+2. `procgen.newMeshDeformationSession()` 持有该网格；`applyImpact()` 用命中点与法向
+   冲量做塑性凹陷，`currentMeshResult()` 取回快照并 `procgen.uploadMesh()` 上传。
+3. 静态目标体（2.8×4.4×2.8）开启命中事件，动态球体弹丸在 X 方向以 12 m/s 射出。
+4. 命中冲量超过 `0.05` 时应用损伤，并隐藏弹丸；随后在第 45 帧之后保存截图。

+| Spline Path | `mesh.subdivide` → `deform.splinePath`（Catmull-Rom 路径，按弧长缩放截面） |
+| Sculpt | `MeshDeformationSession`：inflate 笔刷 + 方向笔刷 + 塑性冲击 |
+| Effector | `deform.effector`（两点密度场） |
+| Interactive Surface | `applySurfaceContact` + `recoverSurface`，以及 `configureColliderRefresh` / `updateColliderRefresh` / `requestColliderRefresh` 的 interval 与 manual 两种碰撞体替换路径 |
+| Slime | `applySlimeImpulse` + `stepSlime`（弹簧-阻尼回弹） |
+| Mesh Fit | `deform.transform` 作为目标面 → `deform.meshFit` 双向贴合 |
+| Vertex Editor | `selectVerticesBox` → `moveSelectedVertices` / `manipulateSelectedVertices` |
+| Sound React | `deform.soundReact`（电平 / 阈值 / 频率驱动变形） |

+# PCG Terrain Detail Overwrite（地形细节覆盖）
+
+验证 **Pcg 细节覆盖**：脚本用 `PointSet` 描述一批草地点（位置、缩放、颜色、`asset`
+字符串属性与稳定 Point ID），把程序化生成的 albedo / normal / mask 三张图烘焙成
+`GrassField` 植被，再用 `setTerrainDetailOverwrite` 一次性覆盖地形的细节距离、淡出
+距离、密度与每 patch 分辨率，并读回校验。整条链路不依赖任何下载资源或运行时 GLSL。
+
+## 运行
+
+```bash
+cd examples/pcg-detail-overwrite
+../../build/linux-debug/src/engine/eve run
+```
+
+或：
+
+```bash
+make run/<platform>-debug GAME=examples/pcg-detail-overwrite
+```
+
+## 验证内容
+
+- 25×17 的草地点阵：逐点 `setScale` / `setColor` / `setStringAttribute(i, "asset", "pcg:detail")`，
+  最后 `assignPointIds("4242")` 固定 Point ID；
+- 32×32 的 RGBA8 albedo / normal / mask 图像逐像素程序化生成（草叶 alpha 与 mask 通道）；
+- `eve.bakeTerrainGrassFoliage(field, points, "pcg:detail", 0.8, 1.25, albedo, normal, mask, foliage)`
+  上传植被，`GrassFoliageSettings` 给出基础色、alpha 裁剪、法线强度、渲染/淡出/硬距离与密度；
+- `field.setTerrainDetailOverwrite(settings)` 覆盖细节参数：Pcg 细节距离 70 / 淡出 18，
+  Unity 细节距离 110 / 密度 0.55 / 每 patch 8；
+- 断言返回质量档位为 `3`（High8）、`getTerrainDetailHardDistance() == 110.0`、
+  `getTerrainDetailDensity() == 0.55`，任一不符即 `throw`。
+
+成功标记：`PCG_DETAIL_OVERWRITE_READY quality=High8 hard=110 density=0.55 fade=70+18 points=<点数>`

+窗口只有 640×360、不可热重载，画面是纯 2D 矩形，因此这个示例基本等同于一个脚本级

+`(0, 0, 1.0, 1.0)` 盖到 5×5、初值 20.0 的目标高度图上；断言 `height(2, 2) == 6.0`
+且 `getStatus() == 3`。
+
+**生成进度**：`updateRule("Terrain", 10, 3, 4, 1)` 加 `updateRuleFraction(0.5)` 之后
+`getProgress()` 必须等于 0.35（容差 1e-4）。
+
+**任务队列**：`add(0.25)` → `tick(0.25)` → `getReadyTaskId()` 必须等于 `add` 返回的 id →
+`resolveReady(true)` 收尾。
+
+另外打印宿主系统探测行 `PCG_HOST_SYSTEM limitFrame=... type=...`。示例保持正常帧循环，
+以便 `scripts/smoke_examples.sh` 能验证它在启动后持续存活。

+# PcgScenePlayer Terrain Culling（场景地形剔除）
+
+验证 `eve.Scene` 上的 **Pcg 地形剔除接口**：给场景节点设置包围盒并打上 `terrain` 标签，
+然后用当前相机与画布尺寸调用 `applyPcgTerrainCullingAt`，只有视锥外的地形节点被隐藏，
+**没有标签的节点必须保持可见**。
+
+## 运行
+
+```bash
+cd examples/pcg-scene-player-culling

+```
+
+或：
+
+```bash

+
+## 验证内容

+- `eve.Scene` 声明式建树：`beginBuild` / `beginNode` / `setBuildPosition` /
+  `setBuildScale` / `end`，再 `mountBuildAs("pcg-scene-player")`；
+- 三个节点：`terrain-visible`（视锥内）、`terrain-culled`（`x = 48`，视锥外）、
+  `landmark-control`（无 `terrain` 标签的对照组）；
+- 通过 `getNodeRef(id).setBounds(-0.5, -0.5, -0.5, 0.5, 0.5, 0.5)` 给地形节点设包围盒，
+  再用 `addTag("terrain")` 打标签；三个节点各自 `linkRenderable3D` 绑定可见物体；
+- `applyPcgTerrainCullingAt("pcg-scene-player", camera, 960.0, 640.0, "terrain")` 返回本次
+  改动的节点数，`!result.ok` 时 `throw`；
+- 读回 `getNodeVisible(...)`：视锥外地形必须被剔除，视锥内地形与无标签对照组必须可见。

+# PCG Underwater Effects（水下效果全链路）
+
+本仓库里覆盖最完整的一个 PCG 示例：把**进入 / 离开水面的整套表现**串成一条链路——
+深度雾与颜色梯度、时间驱动的后期曝光与色彩曲线、水焦散（caustic）投影、水下材质替换、
+三路音频（入水 / 出水 / 循环环境音）、粒子生命周期、触发体、原点平移与地形重力跟随。
+所有采样都是脚本显式驱动的，因此无头运行时结果确定。
+
+## 运行
+
+```bash
+cd examples/pcg-underwater
+../../build/linux-debug/src/engine/eve run
+```
+
+或：
+
+```bash
+make run/<platform>-debug GAME=examples/pcg-underwater
+```
+
+## 验证内容
+
+- **状态推进**：`eve.advanceWaterUnderwaterEffects(state, output, settings, input, depthGradient, timeGradient, postExposureCurve, postColorGradient)`
+  先在水面上"播种"（`cameraY = 6.0`，`timeOfDay = 0.5`），再把相机压到 `4.21` 完成入水；
+  断言 `output.entered`、`output.loopAudio` 与 `causticFrame == 3`；
+- **雾**：`WaterUnderwaterSettings`（`causticTextureCount = 16`、`fogDepth = 20`、
+  `fogDensity = 0.052`、`fogDistance = 42`）配合三段深度雾梯度与两段昼夜雾梯度
+  （`UnderwaterColorGradient.addStop`），经 `eve.applyWaterUnderwaterFog` 写进体积雾；
+- **后期**：`UnderwaterScalarCurve` 的曝光关键帧与后期色彩梯度经
+  `eve.applyWaterUnderwaterPostFx` 应用；
+- **材质**：`WaterSurfaceMaterialSnapshot` 经 `eve.applyWaterUnderwaterMaterial` 替换水下
+  物体着色器/颜色，断言读回的 `getTintR()` 为 0.72；
+- **音频**：`eve.applyUnderwaterAudio(入水, 出水, 循环环境音, ...)` 之后断言环境音
+  `isLooping()` 且 `isPlaying()`；音频文件取自本目录的三个 wav；
+- **水焦散**：`gfx.newTextureFromFile("caustic-cookie.png")` 作为方向光 cookie，
+  在渲染阶段 `fog.projectDirectionalCookie(...)` 投影到深度图；
+- **其它**：粒子发射器生命周期（水面 VFX 暂停、地面粒子被剔除、原点平移后的粒子数）、
+  触发体恢复、地形重力激活、跟随水面的位置与着色器、地平线可见性。
+
+成功标记：

+## 文件
+
+| 路径 | 说明 |
+|---|---|
+| `main.nut` | 入水/出水状态推进、雾与后期与材质 provider、音频、粒子、渲染阶段焦散投影 |
+| `config.nut` | 引擎 `config`：960×640、`hotReload = true` |
+| `caustic-cookie.png` | 方向光水焦散 cookie |
+| `submerge-down.wav` / `submerge-up.wav` | 入水 / 出水音效 |
+| `underwater-loop.wav` | 水下循环环境音 |
+
+## 契约
+
+本示例是可运行示例（`main.nut` + `config.nut`），参与 `scripts/smoke_examples.sh` 的
+帧循环契约：CI 在 Linux 上无头启动它，要求至少 2 秒仍然存活且日志中没有错误标记。

+# Rendering Chain Lab — TAA / SSR / RTGI 与自动反射链运行时对比场景
+
+本示例提供一个固定视角的对比场景，用同一条渲染链交替开关 TAA、SSR、RTGI 与自动反射链
+（`reflectionChain`），让屏幕空间反射、间接光颜色溢出和时间性闪烁/拖影的差异在同一画面上
+直接对照。场景里的反光地面、饱和遮挡盒、五种粗糙度的球体和一根来回移动的细杆，都是为暴露
+这些通道的典型缺陷而摆放的。
+
+## 运行
+
+```bash
+make run/<platform>-debug GAME=examples/rendering-chain-lab
+```
+
+也可以进入示例目录后直接启动引擎：
+
+```bash
+cd examples/rendering-chain-lab && ../../build/linux-debug/src/engine/eve run --debug --mcp-port=7529
+```
+
+Windows 下引擎可执行文件为 `build/win32-debug/src/engine/eve.exe`。脚本头部记录的等价形式是
+`eve run --debug --mcp-port=7529 examples/rendering-chain-lab`。
+
+## 演示内容
+
+- 场景搭建：`buildScene()` 用 `eve.Renderable3D` 配 `gfx.newMeshCube(1.0)` /
+  `gfx.newMeshSphere(40, 24)` 生成反光地面与后墙（`setMetallic(0.72)`、`setRoughness(0.12)`）、
+  红蓝两块高饱和遮挡盒，以及 5 个球体（`setMetallic(0.48)`，粗糙度依次为
+  0.06 / 0.16 / 0.30 / 0.52 / 0.82）和各自的底座。
+- 时间性伪影诱因：细杆 `labMover` 在 `eve_update` 中按 `sin(labTime * 0.82) * 2.8` 横向移动，
+  用来观察 TAA 的闪烁与拖影。
+- 相机与光照：`eve.Camera3D` 设 `setFov(48.0)`、`setAmbient(...)`、`setExposure(0.85)`、
+  `setBloom(0.18, 1.15)` 并 `setActive(true)`；`gfx.setDirectionalLight` 提供主光，两个
+  `eve.Light3D` 暖 / 冷点光源补光，`gfx.setBackgroundColor` 定下暗色基调。
+- 渲染链开关：`configureEffects()` 取 `gfx.getRenderControl()`，先执行
+  `rc.setPostProcessQuality("high")`，再对 `gi`、`rtgi`、`aa`、`taa`、`ssr`、`reflectionChain`
+  逐个 `enable` / `disable`，最后 `rc.compile()`。
+- 反射链是一键式的：开启 `reflectionChain` 会同时打开 `aa`、`taa`、`rtgi` 并关闭 `msaa`，
+  三者共用同一套后处理质量档位。
+- 回调结构：`eve_init` 建场景与 HUD，`eve_update(dt)` 推进动画并处理按键，`eve_render` 依次
+  调用 `gfx.clear()`、`gfx.render3D()`、`ui.beginFrameAndRender()`。
+
+## 操作
+
+| 输入 | 作用 |
+|---|---|
+| `Space` | 在 FULL（TAA + SSR + RTGI + 反射链）与 BASELINE（上述特性全部关闭）之间切换 |
+| `R` / `r` | 复位相机到 `setEye(0.0, 4.4, 12.8)` / `setTarget(0.0, 1.0, -0.8)` |
+
+HUD（`ui.beginWindow("RenderingChainLab")`，经 `ui.mountBuildAs("render-lab-hud")` 挂载为
+宿主叠加层）只显示标题、当前模式和这两条按键提示，没有可点击控件；脚本也没有注册任何鼠标
+操作，相机是固定视角。

+# Shader Live Preview — 实时 GLSL 热重载预览
+
+该示例用一份自定义 GLSL 片元着色器渲染由球体、立方体、圆柱体和地面组成的 3D 预览场景，
+并开启引擎的资产热重载：保存 `shaders/preview.frag` 即会重新编译并事务式替换管线，
+无需重启引擎或重新构建。窗口为 960×540，标题 `EVEngine Live Shader Preview`。
+
+## 运行
+
+```bash
+make run/<platform>-debug GAME=examples/shader-live-preview
+```
+
+也可构建后进入示例目录直接启动引擎：
+
+```bash
+cd examples/shader-live-preview && ../../build/linux-debug/src/engine/eve run
+```
+
+Windows 上引擎可执行文件为 `build/win32-debug/src/engine/eve.exe`。
+
+## 演示内容
+
+- 场景搭建：`eve.Camera3D()` 的 `setEye/setTarget/setUp/setFov/setAmbient/setActive`、
+  `gfx.setDirectionalLight`，以及 `gfx.newMeshSphere(48, 24)`、`gfx.newMeshCube(1.0)`、
+  `gfx.newMeshCylinder(48, 1, true)` 创建的四个 `eve.Renderable3D()` 模型。
+- 模型设置：`setMesh`、`setShader`、`setPosition`、`setScale`、`setTint`、`setRoughness`、
+  `setCastShadow`、`setReceiveShadow`。
+- 自定义着色器：`gfx.newMeshShader(fs.readText("shaders/preview.frag"))`（顶点源码留空），
+  `declareFloat("time")` 声明推送常量，`eve_update` 中每帧 `sendFloat("time", previewTime)`。
+- 片元入口 `main()`：读取 `Frame` UBO 的 `lightDirIntensity` 与 `ambient`，以推送常量 `pc.data[0]`
+  作为时间，混合 `vTint`、漫反射、边缘光，以及随时间摆动的色带与 UV 网格线。
+- 渲染：`gfx.clear()` + `gfx.render3D()`；`eve_update(dt)` 让前三个模型按 `setYaw(previewTime * ...)` 自转。
+
+## 热重载
+
+`config.nut` 中 `hotReload = true`。启动时引擎打印 `hot-reload: watching N path(s)`，
+通过 `hot.watchTree(".")` 监视示例目录整棵树；非 `.nut` 文件变更后调用脚本钩子
+`eve_asset_reload(path)`，`main.nut` 用 `path.find("preview.frag")` 过滤，只处理该文件。
+
+保存 `shaders/preview.frag` 后的流程：`fs.readText("shaders/preview.frag")` 重新读取源码，
+再调用 `gfx.replaceShaderFromGlsl(previewShader, "", source)` 事务式替换管线
+（空顶点源码表示使用该着色器类型的后端默认顶点着色器）。
+编译成功打印 `[shader-preview] reload applied`；失败打印 `[shader-preview] <诊断信息>`，
+保留上一份可用管线，并把状态写入 `reloadMessage`。
+直接编辑 `main()` 中的配色、`bands` 频率或 `grid` 阈值即可立刻看到差别。
+
+## 操作
+
+本示例未注册任何键盘或鼠标输入，没有交互按键。`previewTime` 自动累加驱动动画与推送常量，
+改完着色器保存即可观察热重载效果。
+
+## 相关文件
+
+- `config.nut`：窗口尺寸/标题、`modules = ["gfx", "win", "fs"]` 与 `hotReload` 开关。
+- `main.nut`：搭建预览场景、注册 `eve_asset_reload` 热重载钩子、每帧推送 `time` 并驱动自转。
+- `shaders/preview.frag`：唯一的着色器源码，也是热重载的编辑目标（`#version 450` 片元着色器）。

+# SilPOM vs SSDM — full planar algorithms
+
+Side-by-side comparison of **classic POM**, **SilPOM**, and **planar SSDM**
+on extruded brick cards with hard flat height plateaus.
+
+| Card | Technique | What you should notice |
+| --- | --- | --- |
+| Left (warm) | Classic **POM** | Internal brick depth; **straight geometric** silhouette |
+| Mid (green) | **SilPOM** | Solid heightfield shading; **jagged brick-cap** side limb |
+| Right (cool) | **Planar SSDM** | Same solid march; **continuous** extruded outline |
+
+Cards are **extruded slabs** (local Z = height axis). That is the correct domain
+for silhouette-changing relief. Cylinders are not — a wrapped UV chart cannot
+grow the outline, and a constant depth bias is not SSDM.
+
+## Run
+
+```sh
+make run/linux-debug GAME=examples/silpom-ssdm-compare
+```
+
+Headless smoke (Cloud VM):
+
+```sh
+export VK_ICD_FILENAMES=/usr/share/vulkan/icd.d/lvp_icd.json
+export ALSOFT_DRIVERS=null
+export XDG_RUNTIME_DIR=/tmp/xdg-runtime
+mkdir -p "$XDG_RUNTIME_DIR" && chmod 700 "$XDG_RUNTIME_DIR"
+xvfb-run -a scripts/smoke_examples.sh silpom-ssdm-compare
+```
+
+## Controls
+
+| Key | Action |
+| --- | --- |
+| `O` | Toggle auto-orbit |
+| `A` / `D` | Yaw |
+| `W` / `S` | Pitch |
+| `[` / `]` | Relief scale |
+| `-` / `=` | Max ray-march layers |
+| `1` / `2` / `3` | Focus POM / SilPOM / SSDM |
+
+## Implementation notes
+
+- Shared CPU references: `src/modules/graphics/ParallaxMap.h`
+- Shared GLSL helpers: `src/modules/graphics/shaders/parallax_map.glsl`,
+  `ssdm.glsl`
+- Demo shader is self-contained (`shaders/compare.frag`):
+  - Heightmap is **hard flat brick** with a 1-texel mortar bevel (no soft pillows)
+  - **SilPOM / SSDM** share the solid planar heightfield march (`hit.z` is a
+    hit flag, not softCoverage) so cliff walls shade correctly
+  - Front faces keep geometric depth (cliff FragDepth opens 镂空 shells)
+  - Side faces write hit depth; SilPOM discards low mortar (jagged brick caps);
+    SSDM keeps the continuous profile
+  - Classic POM fades at grazing angles to limit hard-cliff zebra striping
+- Meshes: thin front card for classic POM; extruded slab for SilPOM/SSDM
+- `gl_FragDepth` only pulls toward the camera (Vulkan RH_ZO)
+
+### Regenerating the shader
+
+The fragment stage ships as **committed SPIR-V** (`shaders/compare.frag.spv`),
+loaded with `gfx.loadMeshShaderSpv`, so the example needs no runtime compiler and
+renders the same stages on every host. After editing `shaders/compare.frag`,
+regenerate the committed artifact with:
+
+```sh
+glslc -o shaders/compare.frag.spv shaders/compare.frag
+```
+
+Hot reload (`eve_asset_reload`) recompiles the GLSL live through the engine's own
+compiler; where that is unavailable the panels keep the committed SPIR-V and the
+status line reports it.
+
+## Honesty bound
+
+True screen-space SSDM as a deferred/post pass (pyramid mip + screen warp over
+an already-rendered buffer) is **not** shipped as an engine post here. The demo
+implements the **geometrically correct planar** form: raymarch the heightfield
+inside the extruded volume and write depth from the hit.

+截面挤出三种生成器，覆盖开放路径与闭合回路、逐点截面 / 旋转 / 分块（chunk break）、
+分布采样与沿路径行进（travel）坐标系。没有输入，启动即静态展示。
+
+## 运行
+
+```bash
+cd examples/spline-tube-lab
+../../build/linux-debug/src/engine/eve run
+```
+
+或：
+
+```bash
+make run/<platform>-debug GAME=examples/spline-tube-lab
+```
+
+## 4 个变体
+
+| 变体 | 生成器 | 路径与参数 |
+|---|---|---|
+| 开放管道 | `mesh.splineTube` | 4 点 Catmull-Rom 开放路径、半径 0.48、48 路径段 × 16 径向段、封盖 |
+| 带状体 | `mesh.splineRibbon` | 带坡度的道路路径、宽 1.8、厚 0.28 |
+| 自定义截面 | `mesh.splineExtrude` | U 形开口截面（`setNodeSplineProfile`），沿开放路径挤出 |
+| 闭合回路 | `mesh.splineTube` | `applyShapePreset("circle", 16, 2.0, 0.0, 1.0)` 预置圆环、无缝闭合、半径 0.32 |
+
+细节：
+
+- 逐点轮廓与旋转：`setPointProfile` / `setPointRotation`（管道与道路倾斜）。
+- 分块：`setPointChunkBreak` 把一条样条切成多个 chunk，路径线用 `polylineResult` 分块绘制。
+- 分布与行进：`distributeResult(6, ...)` 取 6 个等距采样点及其朝向，
+  `travelResult` / `travelFrameResult` 取沿路径行进的坐标与 up/side 基向量。
+
+成功标记：
+
+- 控制台打印 `SPLINE_TUBE_LAB_PASS variants=4 open=capped closed=seamless ...`
+- 当前目录写出 `spline-tube-lab.png`

+# Terrain Preview — 直写交换链的 3D 地形预览与视觉审计抓帧
+
+本示例在脚本内用 `procgen` 生成一块 257×257 高度图，经热力、水力与河流三种侵蚀后
+切分成 2×2 个地形区块，并直写交换链渲染完整的 3D 地形。除地表 splat 贴图外，它还按
+高度图与分层数据生成程序化河道与湖面水体，并在演示稳定后自动抓取一帧 PNG 供视觉审计。
+
+## 运行
+
+```bash
+make run/<platform>-debug GAME=examples/terrain-preview
+```
+
+也可以进入示例目录后直接启动引擎：
+
+```bash
+cd examples/terrain-preview && ../../build/linux-debug/src/engine/eve run
+```
+
+Windows 下引擎可执行文件为 `build/win32-debug/src/engine/eve.exe`。
+
+## 演示内容
+
+- 高度图生成：`procgen.newParams()` 配置 `setSize(257, 257)`、`setSeed(20260826)`，
+  以及 `frequency`、`octaves`、`gain`、`ridge`、`warp`、`exponent`、`continent`、
+  `island`、`coast` 等参数，再交给 `procgen.generateHeightmap(params)` 求值。
+- 三层侵蚀：`procgen.erodeTerrainThermal`、`procgen.erodeTerrainHydraulic`、
+  `procgen.erodeTerrainFluvialAdvanced` 依次作用，随后 `procgen.analyzeTerrain`
+  从高度图得到地表分层数据（layers），供后续区块与水体网格使用。
+- 地形区块：`procgen.buildTerrainChunk` 生成 2×2 个 128×128 区块，
+  `procgen.generateTerrainChunkMesh` 转成渲染网格，`procgen.generateTerrainSplatMap`
+  生成反照率贴图，再由 `gfx.newTexture` 上传。
+- 材质：地表用 `procgen.createTerrainMaterialShader`，水体用
+  `procgen.createTerrainWaterShader`；地表 `setMetallic(0.0)` / `setRoughness(0.92)`，
+  水体则 `setMetallic(0.05)`～`0.08`、`setRoughness(0.20)`～`0.12`，比地表更光滑、略更反光。
+- 水系：`procgen.generateTerrainRiverMesh` 与 `procgen.generateTerrainLakeMesh`
+  在高度图与分层数据上生成河道和湖面，非空时各自包成 `eve.Renderable3D`。
+- 相机与光照：`eve.Camera3D` 以 `setEye(62.0, 31.0, 64.0)`、`setTarget(22.4, 4.0, 22.4)`、
+  `setFov(48.0)`、`setAmbient(...)` 俯视地形并 `setActive(true)`；
+  `gfx.setDirectionalLight` 与 `gfx.setBackgroundColor` 设定场景基调。
+
+## 截图
+
+`eve_render` 每帧调用 `gfx.clear()` 与 `gfx.render3D()` 并累计已渲染帧数。当
+`elapsed > 1.5`（约 1.5 秒）且 `renderedFrames >= 8` 时，脚本调用
+`gfx.saveFramePng("/private/tmp/evengine-terrain-preview.png")` 写出这一帧 PNG；
+成功后打印 `terrain preview frame saved: /private/tmp/evengine-terrain-preview.png`
+并把 `saved` 置为 `true`，因此整个进程只抓一帧。
+
+## 相关文件

+# Terrain stamping
+
+This scene compares a procedural source terrain on the left with the processed
+terrain on the right. It uses the native rotated stamp, distance mask, contrast,
+terrace, smooth and thermal kernels. Four mesh chunks per terrain share height
+samples at their boundaries. All input data is generated locally; no Unity package
+or downloaded art is needed. Colors use the existing terrain albedo bake and the
+built-in lit mesh material, so this scene does not depend on runtime GLSL compilation.
+The processed terrain also bakes the Pcg GTS snow and rain albedo branches over
+the splat result. This validates their profile math and ordering; normal,
+smoothness, mask and displacement outputs remain outside this albedo-only pass.
+
+Run the current engine with `eve run examples/terrain-stamping`. For an engine-owned
+capture, add `--debug --mcp-port=7529` and call `eve_screenshot` after the
+`TERRAIN_STAMPING_READY` message. The `pcg_validation` script table exposes readiness,
+frame count and changed samples for integration checks.
+
+This is an integration scene for the implemented kernels, not the complete Pcg
+world workflow. Authoring UI and world-scale orchestration are still being ported.
+Numerical tests live in `test/terrain_stamp/`; rendering must also be
+checked using the newly built host executable.
+
+`TERRAIN_COLLISION_MASK_PASS layers=1` evaluates an owned Pcg radius/layer collision-mask stack before stamping.
+`TERRAIN_POLYGON_MASK_PASS nodes=3` rasterizes a closed Pcg-style PolyMask on the same real runtime path.
+`TERRAIN_WORLD_BIOME_MASK_PASS entries=1` stores, resamples, invalidates, rejects stale data, and rebuilds one
+stable-GUID world-biome baked mask.
+`TERRAIN_GLOBAL_SPAWNER_MASK_PASS` feeds that scalar output through Pcg's image-mask transform, curve, and blend pass.
+`TERRAIN_NOISE_MASK_PASS types=5` evaluates the deterministic native NoiseMask path with fractional fBm and warp.
+`TERRAIN_SMOOTH_MASK_PASS passes=2` evaluates Pcg's horizontal and vertical Smooth ImageMask passes.
+
+
+Startup also runs `validate-image-mask.nut` against real ImageData and owned procgen
+heightmaps. `TERRAIN_IMAGE_ADAPTER_PASS` confirms RGBA8 quantization, RGBA32F row order,
+and atomic rejection of nonfinite pixels/invalid settings. This requires the full
+image module; the CPU-only tests exercise the separate scalar-plane kernel.
+
+
+The stamp now executes through TerrainGenerationSession: reset baseline, record,
+undo, redo, then copy the owned result to the terrain used for rendering.
+`TERRAIN_SESSION_PASS operations=5 staged=1 persisted=1` marks the successful stamp/contrast/terrace/smooth/thermal
+history and full replay. Thermal undo/redo restores sediment together with terrain;
+both outputs are copied from the authoritative session before rendering.
+
+
+The right terrain now includes a native grass detail layer: integer density, stable
+PointSet placement, then direct GrassField foliage upload using the original static RGBA grass image,
+a tangent normal map and a packed metallic/occlusion/thickness/smoothness mask.
+`TERRAIN_GRASS_PASS` checks count preservation, empty resource selection and invalid-width
+rollback. This loads the Pcg-authored texture documented in assets/SOURCE.md and translates the active
+PW foliage shader behavior: distance alpha fade, cutoff, base tint, height snow, packed mask channels,
+normal strength, shadowed directional light and thickness backlighting.
+
+Invalid RGBA32F texture input is rejected while preserving the existing grass field.
+
+For close inspection, call `pcg_validation.closeView()` through eve_eval before capturing.
+
+Grass instances use independent width and height ranges; zero-width upload is rejected without replacing the field.
+
+Terrain trees are exported into PointSet, rendered from one shared procedural tree mesh, and use
+the backend-native tree wind shader. `pcg_validation.treeView()` selects the first tree; the existing
+`freezeWind(seconds,enabled)` helper applies the same explicit snapshot to grass and trees.
+
+Startup also builds a two-tile owned height workspace, stamps across the shared seam, then performs
+an all-tile undo/redo. `TERRAIN_MULTITILE_PASS tiles=2` verifies the runtime binding and transaction.
+It also creates a Pcg-centered two-tile `TerrainWorldWorkspace`; `TERRAIN_WORLD_PASS` verifies stable
+tile naming, unified history, script-driven flatten and spawn clearing, and complete-world undo.
+`TERRAIN_SPAWN_PLAN_PASS rules=4 persisted=1 modifier=1 probe=1` snapshots, restores, then executes an owned terrain
+modifier stamp, texture rule, detail rule, and reflection-probe rule in one stable-ID plan.
+
+`TERRAIN_BIOME_PRESET_PASS spawners=1 persisted=1 staged=1` saves and restores that Pcg-style preset, cancels one
+partial private run, then executes its biome-active stack to one world publication
+through one world transaction.
+It also applies one shared detail window through an owned two-tile detail workspace and restores its
+all-layer history; `TERRAIN_MULTIDETAIL_PASS tiles=2` verifies that Squirrel path.
+The tree path repeats this with one shared RNG stream and renders the copied east-tile points;
+`TERRAIN_MULTITREE_PASS points=4` verifies its transaction before the first present.
+`TERRAIN_PROBE_PASS` verifies deterministic ReflectionProbe placement and the shared Reflection/Light probe contract.
+`TERRAIN_PROBE_PROVIDER_PASS` verifies graphics-owned publication, a bounded real cubemap-face capture tick,
+removal, and stable batch republishing.
+`TERRAIN_WATER_FLOW_MAP_PASS` runs Pcg's separate legacy droplet tracer, axis flip, and in-place smoothing path
+before rendering; it is intentionally distinct from the hydraulic flux/sediment simulation.
+`TERRAIN_VELOCITY_FLOW_PASS` executes `HeightMap.FlowMap`'s fixed-step four-direction flux and normalized final
+velocity magnitude as a third, separately validated water-derived scalar resource.
+`TERRAIN_DERIVED_MAP_PASS` evaluates the separate `HeightMap.CurvatureMap` differential geometry and
+`HeightMap.Aspect` orientation conventions before the render path starts.
+`TERRAIN_TERRACE_REMOVAL_PASS` runs Pcg 4.2.2's classify, adaptive smooth, gradient-noise, directional-filter,
+and Gaussian de-terracing pipeline with an explicit deterministic noise seed.
+The splat path paints normalized texture weights across two owned tiles and restores all layers;
+`TERRAIN_MULTISPLAT_PASS tiles=2` verifies its copy and undo/redo transaction.
+`TERRAIN_SPLAT_ALBEDO_PASS pixels=1024` confirms that the three-layer packed texture result is uploaded as
+RGBA8 and used by the processed terrain before the first present.
+`TERRAIN_GTS_HEIGHT_BLEND_PASS layers=3 transition=0.18` confirms all three normalized splat weights are
+recomputed from transformed material heights before the albedo and later GTS stages consume them.
+`TERRAIN_GTS_PACKED_LAYERS_PASS layers=3 outputs=4` confirms real per-layer textures, UVs, normals, AO,
+smoothness, geological strength and detail strength replace the former constant-color visualization path.
+`TERRAIN_GTS_LAYER_PROJECTION_PASS triplanar=1 stochastic=1` confirms one layer uses the exact GTS
+world-space three-plane projection and another uses its TriangleGrid/hash anti-tiling branch.
+`TERRAIN_GTS_LAYER_DISPLACEMENT_PASS top=4 outputs=2` confirms the same packed layer set drives the GTS
+top-four albedo-alpha displacement and tessellation pass before snow modifies those outputs.
+`TERRAIN_GTS_GLOBAL_BLEND_PASS camera=137,96,151` confirms the shared near/far raster is generated from the
+actual demonstration camera using the GTS squared-distance formula.
+`TERRAIN_GTS_COLORMAP_PASS near=0.22 far=0.72` confirms the source-order near/far colormap blend.
+`TERRAIN_GTS_GEOLOGICAL_PASS near=8 far=19 outputs=2` confirms height-axis near/far geological color and
+packed tangent-normal overlays are committed together before weather.
+`TERRAIN_GTS_DETAIL_PASS near=7 far=23 outputs=3` confirms near/far detail normals, layer-weighted
+micro-shadowing, and the detail raster subsequently consumed by snow shading.
+`TERRAIN_GTS_WEATHER_PASS snow=1 rain=1 pixels=1024` confirms that the same image then receives height/slope snow
+and bounded-altitude rain darkening before upload.
+`TERRAIN_GTS_VARIATION_PASS scales=3 intensity=0.72` confirms that three world-space repeating samples modulate
+the result after weather, matching the GTS material order.
+`TERRAIN_GTS_PBR_PASS outputs=4 time=2` executes the packed mask, renderer-ready tangent normal, displacement and tessellation
+branches with an explicit deterministic rain-animation time.
+`TERRAIN_GTS_MATERIAL_PASS packedNormalMask=1 parallax=1` uploads the packed tangent normal/AO/smoothness
+texture and displacement-derived height texture to every processed-terrain renderable.
+`TERRAIN_TEXTURE_MASK_PASS layer=1` confirms the selected Pcg terrain-texture weight is copied into a scalar
+mask source before the same splatmap is rendered.
+The game-object path executes one multi-resource rule through a two-tile owned workspace with a shared
+Pcg RNG stream and seam collision domain; `TERRAIN_MULTIOBJECT_PASS` verifies copy and undo/redo.
+
+
+Grass now uses the PW wind main/branch/leaf deformation with an explicit update clock.
+The same update owns a looping, listener-relative procedural wind-noise Source and applies Pcg WindManager's
+source-specific volume transition through `VegetationWindAudioState`; `TERRAIN_WIND_PASS audio=0.2 looping=1`
+checks the real audio object before the first presented frame.
+For repeatable comparisons, call `pcg_validation.freezeWind(2.0, true)` or
+`pcg_validation.freezeWind(0.0, false)` after `closeView()`. Strength 1 intentionally
+exercises large source deformation. The example uses typed VegetationWindState/Profile, checked advanceVegetationWind and
+applyGrassWind operations. TERRAIN_WIND_PASS verifies invalid distance rejection at startup.
+
+`TERRAIN_NEIGHBORHOOD_FILTER_PASS` runs Pcg-compatible `HeightMap.DeNoise`, `GrowEdges`, and
+`ShrinkEdges` over the generated terrain while preserving their order-dependent in-place traversal.
+`TERRAIN_HEIGHTMAP_FILTER_PASS` covers Pcg's four-neighbor smooth, radius-five sliding-window smooth,
+and odd-square in-place convolution through the public Squirrel API.
+`TERRAIN_SLOPE_QUANTIZE_PASS` validates Pcg's normalized `SlopeMap` gradient and scalar `Quantize`
+midpoint rounding through the same runtime path.
+`TERRAIN_HEIGHTMAP_ARITHMETIC_PASS` runs scalar and raster arithmetic, clamping, mismatched-raster
+resampling, and masked lerp through the public bindings.
+`TERRAIN_HEIGHTMAP_TRANSFORM_PASS` runs the unmasked Pcg normalize and direct-exponent power transforms;
+the same API also exposes invert and source-formula contrast.
+`TERRAIN_HEIGHTMAP_COPY_PASS` covers conditional Copy and resampled CopyClamped with a smaller output raster.
+`TERRAIN_HEIGHTMAP_FLIP_PASS` verifies Pcg's rectangular matrix-transpose meaning of `HeightMap.Flip`.
+`TERRAIN_HEIGHTMAP_MEASURE_PASS` reads min, max, average, and scanner edge base level from current samples.
+`TERRAIN_TERRACE_QUANTIZE_PASS` executes Pcg's multi-terrace curve overload using native sampled curve rows.
+`TERRAIN_SLOPE_QUERY_PASS` executes all three Pcg point-slope formulas and reports their distinct units.
+`TERRAIN_HEIGHTMAP_WRITE_PASS` covers clamped fill, safe-border writes, Pcg row/column orientation, and reset.
+`TERRAIN_PCG_RAW_PASS` decodes headerless Pcg RAW8 bytes through `Procgen.loadTerrainBytes`; RAW16 little-
+and big-endian paths share the tested native decoder.
+`TERRAIN_LEGACY_HYDRAULIC_PASS` runs the separate `HeightMap.ErodeHydraulic` CPU loop with periodic rain,
+persistent four-way flux, hardness-controlled dissolution and atomic terrain/sediment publication.
+`TERRAIN_LEGACY_THERMAL_PASS` runs both active legacy CPU erosion variants: synchronous cardinal
+redistribution and ordered steepest-neighbor transfer with a resampled hardness map.
+`TERRAIN_HEIGHTMAP_ACCESS_PASS` verifies border-clamped integer reads, Pcg normalized bilinear reads,
+data presence and two-dimensional power-of-two classification.

+# TileWorld Graph Dungeon
+
+Asset-free 3D example for the TileWorldCreator-style graph port.
+
+The live path is:
+
+`GridGraph(GeneratorRegistry(level.roguelike) -> semantic layers -> autotile -> random selection -> grid-to-points)`
+`-> PointGraph(transform)`
+`-> BuildLayerStack + IncrementalBuildExecutor(cluster delta)`
+`-> MeshGraph(grid tiles + point instancing)`
+`-> MeshBuild -> Vulkan renderables`.
+
+The example uses four independent build layers:
+
+- autotile-mask floor groups with per-group material tints;
+- a raised boundary-wall layer extracted from the roguelike generator's wall-autotile masks;
+- a gold navigation layer produced by `grid.path` between deterministic endpoints;
+- sparse procedural rock instances generated through PointGraph.
+
+The example executes the stack through an 8x8-cell incremental cluster cache.
+Its scene cache consumes each upsert/removal delta to replace or hide only the
+affected floor and prop renderables, then repeats the same update to prove the
+stable delta is empty. Each live cluster also owns a static triangle-mesh
+collider derived from the exact same floor artifact. Collider replacement is
+construct-before-destroy, and removal destroys the matching body. When the
+`physics` module is trimmed, this optional consumer is visibly reported as
+`physics=disabled` and rendering continues. The example does not execute a
+second full-stack preview build.
+
+- `R`: regenerate with the next deterministic seed.
+- `Space`: pause/resume the camera orbit.
+
+Run from the repository root:
+
+```powershell
+make run/win32-debug GAME=examples/tileworld-graph-dungeon
+```

+# UV 贴图绘制：点击网格把 Box3D 三角形命中映射回模型 UV 并绘制贴图
+
+示例加载 `paintable.obj` 中的平面四边形，并把它同时注册为可渲染模型和 Box3D 静态三角网格碰撞体。
+鼠标左键点击时，示例用相机屏幕射线在物理世界中做三角形拾取，把命中的世界空间点通过
+`model.mapSurfacePointToUv` 映射回模型 UV，再在 512×256 的 RGBA8 贴图上绘制圆形笔刷并上传给 GPU。
+渲染体与碰撞体都是单位变换，所以世界空间命中点即模型本地坐标。
+
+## 运行
+
+```sh
+make run/<platform>-debug GAME=examples/uv-texture-paint
+```
+
+```sh
+cd examples/uv-texture-paint && ../../build/linux-debug/src/engine/eve run
+```
+
+Windows 下可执行文件路径为 `build/win32-debug/src/engine/eve.exe`。
+
+## 演示内容
+
+- 相机屏幕射线：`camera.screenToRay(mouse.getX(), mouse.getY(), gfx.getWidth().tofloat(), gfx.getHeight().tofloat())`，再用 `getScreenRayOriginX/Y/Z` 与 `getScreenRayDirX/Y/Z` 取出射线，向方向延长 100.0 作为终点。
+- 物理三角形拾取：`physics.newWorld3D(0.0, 0.0, 0.0, false)` 建世界，`world.newBody("static", ...)` 加静态刚体，`body.newTriangleMeshShape(vertices, indices)` 的顶点与索引直接由 `model.getVertexPosition(0, vertex, component)` 和 `model.getFaceVertexIndex(0, triangle, corner)` 展开；`world.rayCast(...)` 后用 `world.hasRayHit()`、`world.getRayHitTriangleIndex()`、`world.getRayHitX/Y/Z` 读取命中结果。
+- UV 回映射：`model.mapSurfacePointToUv(0, world.getRayHitTriangleIndex(), hitX, hitY, hitZ, 0)` 返回 `SurfaceUv`，由 `uv.getTriangleIndex()`、`uv.getU()`、`uv.getV()` 给出三角形与 UV 坐标。
+- 贴图绘制与上传：`eve.Image().newEmptyImageData(512, 256, "RGBA8")` 建图，逐像素 `pixels.setPixel(...)` 写入水平渐变（r 从 0.12 递增到约 0.30，g 0.28，b 0.55），`gfx.newTexture(pixels, false, false)` 建纹理并由 `renderable.setTexture(texture)` 绑定；命中后 `pixels.paintCircleUv(u, v, 14.0, 1.0, 0.12, 0.04, 1.0, false, false)` 画笔刷，再 `gfx.updateTextureFromImageData(texture, pixels)` 把改动刷到显存。
+- 模型来源：`model3d.newModelDataFromFile("paintable.obj")` + `model3d.createRenderable(gfx, model, 0)`；`eve_render` 中 `gfx.clear()` 后 `gfx.render3D()`，背景色为 `gfx.setBackgroundColor(0.04, 0.06, 0.09, 1.0)`。
+
+## 操作
+
+- 鼠标左键（`mouse.isDown(1)`）：按下瞬间（上一帧未按下）触发一次 `paintHit()`，在命中 UV 处画半径 14 像素、颜色 (1.0, 0.12, 0.04)、不透明的圆；按住不放不会连续绘制，需要松开后再次点击。
+- 鼠标位置（`mouse.getX()` / `mouse.getY()`）决定屏幕射线，从而决定落笔位置。
+- 代码中没有键盘绑定，唯一的输入检测就是上述左键。
+
+## 输出
+
+示例不写任何磁盘文件，绘制只发生在内存中的 512×256 RGBA8 `ImageData` 与 `Texture` 上，退出后不保留；
+每次绘制会向控制台打印 `paint: triangle=<n> uv=(<u>, <v>)`。
+
+## 相关文件
+
+- `main.nut` — 全部示例逻辑：相机、模型加载、物理世界与三角网格、射线拾取、UV 映射、贴图绘制与上传。
+- `config.nut` — 窗口标题 `UV Texture Paint`，窗口尺寸 960×640。

+# Virtual Texture Blending — 虚拟纹理材质混合
+
+本例演示 `Material.setVirtualTexture()`：把两个 64×64 的常驻虚拟页和一个 fallback 槽拼进同一张
+3 槽物理图集，用页表把虚拟页映射到物理槽位。每个页槽四周留 2 像素 gutter 重复相邻边缘颜色，
+让页边界与页切换在 `textureGrad` 采样下不产生接缝。
+
+## 运行
+
+```bash
+make run/<platform>-debug GAME=examples/virtual-texture-blending
+```
+
+也可以直接运行引擎（Windows 下把路径换成 `build/win32-debug/src/engine/eve.exe`）：
+
+```bash
+cd examples/virtual-texture-blending && ../../build/linux-debug/src/engine/eve run
+```
+
+## 演示内容
+
+- 图集由 `eve.Image().newEmptyImageData(w, h, "RGBA8")` 程序化生成：`tile = 64`、`border = 2`，
+  每槽 `slotSize = 68`，横向 3 槽共 204×68。槽 0 是 fallback 槽（整面替身、无页边界），
+  槽 1、槽 2 是两个物理页，各存整条岩石→苔藓渐变的一半。
+- 页表是 2×1 RGBA8：红/绿存物理槽中心（0.5 → 槽 1，0.833333 → 槽 2），蓝 > 0.5 表示该页常驻。
+  `virtual_texture.glsl` 正是按 `entry.b` 分流：命中取页内 uv，未命中回落到整面 uv 并缩放梯度。
+- 本例只有 2 个虚拟页且都常驻，所以页表两项的蓝通道都是 1，运行时全部走页路径。
+- `gfx.newTexture(image, false, false)` 上传 albedo 图集、平面法线图集和页表，然后调用
+  `vtMaterial.setVirtualTexture(albedo, normal, pageTable, 2, 1, 3, 1, border / slotSize)`：
+  2×1 个虚拟页、3×1 个物理槽、border fraction = 2/68。
+- 材质参数为 `setRoughness(0.78)` 与 `setMetallic(0.0)`。
+- 地面是 `eve.Renderable3D()` 加 `gfx.newMeshCube(1.0)`，缩放到 (11, 0.35, 7)。
+- 相机 `eve.Camera3D()`：eye (0, 7, 9)、target 为原点、fov 52°，环境光 (0.28, 0.30, 0.32)，

+# Voxel — 流式体素地形与方块建造示例
+
+自包含的最小体素示例：脚本侧注册方块类型并程序化生成 4×4 图集，用内置噪声地形
+（`setTerrain` + `streamAround`）自动流式补建玩家周围的 chunk，再通过 DDA 射线
+拾取实现按名字放置与破坏方块。与 `examples/voxel-terrain`（结合 `procgen` 的
+`TerrainSampler`、WASD 飞行与编辑器笔刷）相比，本示例只做最小闭环：脚本程序化
+图集 + 内置噪声地形 + 自动环绕相机。
+
+## 运行
+
+```sh
+make run/<platform>-debug GAME=examples/voxel
+```
+
+也可以直接进入示例目录运行引擎（Linux）：
+
+```sh
+cd examples/voxel && ../../build/linux-debug/src/engine/eve run
+```
+
+Windows 下可执行文件为 `build/win32-debug/src/engine/eve.exe`。
+
+## 演示内容
+
+- 方块类型注册表：`voxel.newCubeTypes()` 加 `loadFromJson`，注册 `grass`、`stone`、
+  `wood` 三种方块，用 `faceTex` 指定每个面的图集编号。
+- 程序化图集：`gfx.newCanvas` 绘制 4×4 个 32 像素图块（1 草顶、2 泥土、3 石头、
+  4 木头），转成纹理后交给 `world.drawVisible(gfx, atlas, TILES_PER_ROW)`。
+- 地形：`world.setTerrain(20260822, 1, 2, 3, 8.0, 14.0, 1.0 / 32.0)` 配置种子、
+  草/土/石纹理 id、基准高度、幅度与缩放。
+- 流式加载：`world.streamAround(0, 0, 0, 2)` 以球形半径 2 个 chunk 自动补建。
+- 网格更新：`world.remeshDirty()` 重建脏 chunk（含边界接缝）。
+- 剔除与绘制：`world.selectVisible(...)` 传入 16 个 float 的 view-proj 做视锥剔除，
+  随后 `gfx.setMesh3DViewProj` / `gfx.setMesh3DView` / `gfx.setMesh3DCameraPos`
+  与 `gfx.begin3DFrame()`。
+- 射线拾取：`cam.screenToRay` 生成屏幕射线，`world.raycast(...)` 命中后用
+  `getRaycastHitX/Y/Z` 与 `getRaycastPrevX/Y/Z` 取命中块与前一格空气块。
+- 相机：单个 `eve.Camera3D`（`setActive(false)`，只用来算矩阵和射线）。
+
+## 操作
+
+- 鼠标左键点击：在命中面前一格的空气位置放置木头块（`setVoxelByName(..., "wood")`）。
+- 鼠标右键点击：破坏命中方块（`setVoxel(hx, hy, hz, 0)`）。
+- `R`：立即重建所有脏 chunk（`keyboard.isDown("r")` → `remeshDirty()`）。
+- 相机自动环绕：代码用 `elapsed` 的 sin/cos 驱动 `setEye`，没有键盘移动键。

+"""Enforce the examples/ layout contract.
+
+Every directory under ``examples/`` is one of two reviewed kinds:
+
+* a **runnable example** -- it owns ``main.nut`` plus a ``config.nut`` that
+  assigns the engine ``config`` table, and it is executed by
+  ``scripts/smoke_examples.sh`` in CI; or
+* a **non-runnable sample** -- a C++/plugin/asset package that is explicitly
+  listed in :data:`NON_RUNNABLE_EXAMPLES` with the reason it cannot be started
+  by ``eve run``.
+
+Both kinds must own a ``README.md``, and every example must appear in the
+``examples/README.md`` overview so the directory stays discoverable.
+
+The runtime half of the contract lives in ``scripts/smoke_examples.sh``: every
+directory that this gate classifies as runnable is launched for at least
+``MIN_RUN_SECONDS`` and must still be alive, with no error markers, when the
+harness kills it.  A new example therefore cannot reach ``dev`` without either
+surviving that smoke run or being added to the reviewed exemption list here.
+
+Usage::
+
+    python3 scripts/check_examples.py
+    python3 scripts/check_examples.py --json

+"""Tests for scripts/utf8_stdio.py and the convention it enforces.
+
+The failure being guarded is Windows-local and depends on redirection: CI runs
+the checkers on Linux where stdout is UTF-8, but on a Windows host a *piped*
+stdout is encoded with the ANSI code page from the locale -- cp936 (GBK) on a
+Chinese Windows.  A checker that prints text read back out of the tree (an
+example README title containing "↔", for instance) then dies with
+``UnicodeEncodeError`` instead of reporting its verdict.
+
+Two halves are covered here:
+
+* the helper's behaviour, including a real child process running under a forced
+  CP936 stdio encoding, and
+* the repository conventions -- every ``scripts/*.py`` program (a module with a
+  ``__main__`` guard) calls the helper, every module that is *not* a program
+  keeps its import side-effect free by not printing at all, and no script or
+  script test inherits the host locale for text file I/O.  That last rule is the
+  input-side twin of the stdio problem: ``Path.read_text()`` without
+  ``encoding=`` decodes UTF-8 repository text as CP936 on a Chinese Windows and
+  raises ``UnicodeDecodeError``.
+
+The test-runner side (``python3 -m unittest``) is covered by the ``-X utf8``
+flag on the Makefile/CI invocations, because a test module is imported by the
+runner rather than being its own entry point.

+#!/usr/bin/env python3
+"""Make a repository script's text streams UTF-8 on every host.
+
+CI runs these scripts on Linux, where ``sys.stdout`` and ``sys.stderr`` are
+UTF-8.  A Windows host is not automatically UTF-8: as soon as the output is
+redirected -- an IDE terminal, ``> log.txt``, ``| tee``, or a tool capturing the
+command -- Python encodes text with the ANSI code page from the locale, which is
+cp936 (GBK) on a Chinese Windows.  Printing a diagnostic containing a character
+that code page cannot represent then raises ``UnicodeEncodeError`` and turns a
+checker into a traceback.
+
+That is reachable, not theoretical: this repository is full of characters cp936
+cannot encode (``↔``, ``²``, ``³``, ``⇒``, ``•``, emoji), and checkers print text
+they read back out of the tree -- for example ``scripts/check_examples.py
+--print-missing-rows`` prints each example README's own title.
+
+Call :func:`enable_utf8_stdio` once from a program's entry point, never at import
+time, so importing a script module stays free of side effects::
+
+    import utf8_stdio
+
+    ...
+
+    if __name__ == "__main__":
+        utf8_stdio.enable_utf8_stdio()
+        raise SystemExit(main())
+
+``scripts/tests/test_utf8_stdio.py`` enforces that convention for every program
+under ``scripts/``, and pins the failure this module exists to remove.
+
+Scope: this normalises the process's *text streams*.  It cannot change the
+locale-derived default that ``open()`` and ``subprocess`` use for *other* text,
+so code that decodes a child process or writes a data file must still pass
+``encoding="utf-8"`` explicitly; the Makefile/CI paths that run unit tests use
+``python3 -X utf8`` so runner-generated text is UTF-8 too.

+// the heightfield in world/view space and write FragDepth from the hit — that is
+// the geometrically correct planar form of SSDM / relief mapping.

+/**
+ * @brief An editable hex map wrapped onto a sphere.
+ *
+ * This is the spherical counterpart of `HexMap`. It reuses the whole
+ * per-cell data model unchanged — `HexCellData`, `HexValues` and `HexFlags` —
+ * and the geometry constants of `HexMetrics`, and replaces only the two things
+ * that cannot survive the change of surface: cell **identity** and the
+ * **neighbour relation**.
+ *
+ * Cell identity is a dense `HexSphereCell` id from `HexSphereTopology` instead
+ * of axial/offset `HexCoordinates`, and neighbours are reached through the
+ * topology's half-edge tables instead of integer direction offsets. There is no
+ * chunk grid: the topology already gives every cell a stable id over the whole
+ * sphere, so dirty tracking is per cell.
+ *
+ * Elevation is radial. A cell's surface sits at
+ * `sphereRadius + elevation * elevationStep`, so `elevationStep` is the world
+ * distance one elevation level lifts the surface, and it defaults to a fraction
+ * of the radius rather than to the planar `HexMetrics::kElevationStep` (three
+ * world units), which would be an absurd relief on a planet-sized sphere. The
+ * editable range, the packed layout and every clamping rule stay exactly those
+ * of `HexValues`.
+ *
+ * Direction indices are the topology's edge indices in
+ * `[0, neighborCount(cell))`, i.e. six for a hexagon and five for a pentagon.
+ * `HexFlags` stores roads and rivers in six one-bit slots indexed by
+ * `HexDirection`, so a direction index is cast into that enumeration directly;
+ * slot 5 is simply never set on a pentagon.
+ *
+ * Ownership and lifetime: a value type owning its topology, its cell storage and
+ * its noise field. It performs no I/O, opens no GPU resources and invokes no
+ * callbacks.
+ *
+ * Thread affinity: affine to one thread, like `HexMap`. The type is not
+ * synchronized.
+ *
+ * Determinism: the topology, the noise field and every derived position depend
+ * only on the subdivision level, the radius and the seed. Two maps built with
+ * the same triple produce identical topology, cell storage and positions.

+ * @brief Builds the ground, terrace and cliff surface of a spherical hex map.
+ *
+ * This is the spherical counterpart of `buildTerrainMesh`. The whole sphere is one
+ * mesh, because the topology gives every cell a global id and the surface has no
+ * chunk borders to hide a seam in.
+ *
+ * The construction is the same corner-matrix scheme the planar builder uses, with
+ * the three planar assumptions replaced:
+ *
+ * - **Edge count.** A cell has five edges if it is pentagonal and six otherwise, so
+ *   nothing iterates a fixed six directions.
+ * - **Edge ownership.** The planar builder leans on the chunk grid (`direction <= SE`)
+ *   to emit every shared boundary exactly once. A sphere has no chunk grid, so the
+ *   *lower cell id* owns the edge instead: the strip across `cell -> neighbour` is
+ *   built only while `cell < neighbour`. The rule is a total order on the same set of
+ *   edges, so it still emits each shared boundary exactly once.
+ * - **"Vertical" is radial.** Positions are built as a unit direction times a radius,
+ *   and the terrace interpolation of a slope moves *along the surface* by the
+ *   horizontal step and *outward* by the vertical step, instead of moving in XZ and Y.
+ *
+ * All three terrain layers are encoded exactly as the planar builder encodes them
+ * (see `HexTerrainVertexCode`), so `mesh3d`'s terrain shader consumes this mesh
+ * unchanged.
+ *
+ * @param map Source map. An empty map produces an empty mesh.
+ * @param out Destination mesh; cleared and finalized by this call.

+ * neighbouring flooded cells share their corners exactly and the ocean is one
+ * closed sheet with a clean edge where it meets land.
+ *
+ * The texture coordinates follow the same contract as the planar water mesh: `u` is
+ * the shore parameter (`0` in open ocean, `1` where the water ends against land)
+ * and `v` is reserved.

+ * @brief Icosahedral (Goldberg) hex topology for a spherical hex map.
+ *
+ * The polyhedron is the dual of a geodesic sphere: an icosahedron subdivided
+ * `subdivision` times at frequency `f = 2^subdivision`, whose **vertices** become
+ * the cells. A cell therefore has six neighbours, except the twelve cells that
+ * descend from the original icosahedron vertices, which have five. That makes
+ * `cellCount() == 10 * f^2 + 2` and `pentagonCount() == 12` for every level,
+ * matching the `mesh.hexplanet` recipe of the procgen module.
+ *
+ * Cell ids are dense and stable: cells `[0, 12)` are exactly the twelve
+ * pentagons, because midpoint subdivision never renumbers the original vertices.
+ *
+ * Directions are not arithmetic. The six planar directions of `HexMetrics` are
+ * constant integer offsets in one global frame; on a sphere the edge order around
+ * a cell depends on the cell, and a pentagon has only five edges, so there is no
+ * `opposite(direction)` offset that works everywhere. Every cross-edge query goes
+ * through `directionOf` instead.
+ *
+ * Direction `d` of a cell is the edge between `corner(d)` and
+ * `corner((d + 1) % neighbourCount)`. Both corners are shared with the neighbour
+ * across that edge, in the opposite order, which is what lets a mesh builder walk
+ * a boundary from either side.
+ *
+ * Ownership and lifetime: a value type owning three flat arrays; no I/O, no GPU
+ * resources, no callbacks. Immutable once built, so it is safe to share.
+ *
+ * Determinism: the construction is a pure function of `subdivision`; two builds
+ * at the same level produce identical ids, directions, neighbours and corners.

+ * result:
+ *
+ * - the wedge is **subdivided into four triangles** along a five-sample water edge, so
+ *   the water edge tessellates like the bank it meets; and
+ * - the strip is **flat at the water height** - the far edge only carries the
+ *   neighbour's solid corner *positions*, never the neighbour's elevation. A strip
+ *   that tilts up to the bank instead reads as a bright band tracing every hexagon
+ *   edge, which is exactly the seam this port exists to avoid. The bank terrain
+ *   simply rises through the flat water, and the far edge's foam parameter marks where.
+ *
+ * @param map Source map.
+ * @param coordinates Flooded cell the strip belongs to.
+ * @param direction Direction towards the land neighbour.
+ * @param centre Water-surface centre of `coordinates`.
+ * @param noise Map noise.

+scientific works ("Commons") that the public can reliably and without fear
+of later claims of infringement build upon, modify, incorporate in other
+works, reuse and redistribute as freely as possible in any form whatsoever
+and for any purposes, including without limitation commercial purposes.
+These owners may contribute to the Commons to promote the ideal of a free
+culture and the further production of creative, cultural and scientific
+works, or to gain reputation or greater distribution for their Work in
+part through the use and efforts of others.
+
+For these and/or other purposes and motivations, and without any
+expectation of additional consideration or compensation, the person
+associating CC0 with a Work (the "Affirmer"), to the extent that he or she
+is an owner of Copyright and Related Rights in the Work, voluntarily
+elects to apply CC0 to the Work and publicly distribute the Work under its
+terms, with knowledge of his or her Copyright and Related Rights in the
+Work and the meaning and intended legal effect of CC0 on those rights.
+
+1. Copyright and Related Rights. A Work made available under CC0 may be
+protected by copyright and related or neighboring rights ("Copyright and
+Related Rights"). Copyright and Related Rights include, but are not
+limited to, the following:
+
+  i. the right to reproduce, adapt, distribute, perform, display,
+     communicate, and translate a Work;
+ ii. moral rights retained by the original author(s) and/or performer(s);
+iii. publicity and privacy rights pertaining to a person's image or
+     likeness depicted in a Work;
+ iv. rights protecting against unfair competition in regards to a Work,
+     subject to the limitations in paragraph 4(a), below;
+  v. rights protecting the extraction, dissemination, use and reuse of data
+     in a Work;
+ vi. database rights (such as those arising under Directive 96/9/EC of the
+     European Parliament and of the Council of 11 March 1996 on the legal
+     protection of databases, and under any national implementation
+     thereof, including any amended or successor version of such
+     directive); and
+vii. other similar, equivalent or corresponding rights throughout the
+     world based on applicable law or treaty, and any national
+     implementations thereof.
+
+2. Waiver. To the greatest extent permitted by, but not in contravention
+of, applicable law, Affirmer hereby overtly, fully, permanently,
+irrevocably and unconditionally waives, abandons, and surrenders all of
+Affirmer's Copyright and Related Rights and associated claims and causes
+of action, whether now known or unknown (including existing as well as
+future claims and causes of action), in the Work (i) in all territories
+worldwide, (ii) for the maximum duration provided by applicable law or
+treaty (including future time extensions), (iii) in any current or future
+medium and for any number of copies, and (iv) for any purpose whatsoever,
+including without limitation commercial, advertising or promotional
+purposes (the "Waiver"). Affirmer makes the Waiver for the benefit of each
+member of the public at large and to the detriment of Affirmer's heirs and
+successors, fully intending that such Waiver shall not be subject to
+revocation, rescission, cancellation, termination, or any other legal or
+equitable action to disrupt the quiet enjoyment of the Work by the public
+as contemplated by Affirmer's express Statement of Purpose.
+
+3. Public License Fallback. Should any part of the Waiver for any reason
+be judged legally invalid or ineffective under applicable law, then the
+Waiver shall be preserved to the maximum extent permitted taking into
+account Affirmer's express Statement of Purpose. In addition, to the
+extent the Waiver is so judged Affirmer hereby grants to each affected
+person a royalty-free, non transferable, non sublicensable, non exclusive,
+irrevocable and unconditional license to exercise Affirmer's Copyright and
+Related Rights in the Work (i) in all territories worldwide, (ii) for the
+maximum duration provided by applicable law or treaty (including future
+time extensions), (iii) in any current or future medium and for any number
+of copies, and (iv) for any purpose whatsoever, including without
+limitation commercial, advertising or promotional purposes (the
+"License"). The License shall be deemed effective as of the date CC0 was
+applied by Affirmer to the Work. Should any part of the License for any
+reason be judged legally invalid or ineffective under applicable law, such
+partial invalidity or ineffectiveness shall not invalidate the remainder
+of the License, and in such case Affirmer hereby affirms that he or she
+will not (i) exercise any of his or her remaining Copyright and Related
+Rights in the Work or (ii) assert any associated claims and causes of
+action with respect to the Work, in either case contrary to Affirmer's
+express Statement of Purpose.
+
+4. Limitations and Disclaimers.
+
+ a. No trademark or patent rights held by Affirmer are waived, abandoned,
+    surrendered, licensed or otherwise affected by this document.
+ b. Affirmer offers the Work as-is and makes no representations or
+    warranties of any kind concerning the Work, express, implied,
+    statutory or otherwise, including without limitation warranties of
+    title, merchantability, fitness for a particular purpose, non
+    infringement, or the absence of latent or other defects, accuracy, or
+    the present or absence of errors, whether or not discoverable, all to
+    the greatest extent permissible under applicable law.
+ c. Affirmer disclaims responsibility for clearing rights of other persons
+    that may apply to the Work or any use thereof, including without
+    limitation any person's Copyright and Related Rights in the Work.
+    Further, Affirmer disclaims responsibility for obtaining any necessary
+    consents, permissions or other rights required for any use of the
+    Work.
+ d. Affirmer understands and acknowledges that Creative Commons is not a
+    party to this document and has no duty or obligation with respect to
+    this CC0 or use of the Work.
