 ## 移植铁律
 
+- **验证前置条件优先。** 验证时，先准备前置条件，之后再验证；前置条件准备也必须考虑依赖关系和先后顺序，以提高验证的准确性和效率。按依赖顺序准备构件与资源、运行环境、服务与接口、数据与场景；前置条件不满足时先补齐，不重复运行依赖它的下游验证。复用仍有效的前置检查结果，环境或依赖变化后仅重新检查受影响项；如实记录缺项、失败及验证范围。
+- **按合理的小批次推进。** 每批只处理一个明确业务缺口及其必要调用链；单次读源码≤30行、修改≤2文件且增删合计≤10行（含交接）。按实际字节控制提交提示、交接与工具输出，区分已统计内容与系统附加内容；断流/超量后缩小下一批，连续稳定交接后才有界放宽。达到预算先保留源码与continuationNotes（断点、已完成、残余、下一动作）再续接，禁止堆叠全量历史、盲目重发大包或靠删缺口缩量；不改变实现期禁止验证的规则。
+- **当前工作定位：用户明确“桌面 Blender → Web Blender 移植”基本完成，后续仅以补充具体功能缺口为主，不得重新开展整体移植或偏离主线。科学、高效率地充分复用已有源码、模块、适配接口、WASM 和应用产物，使操作者能使用全面完整的功能。**

+- 无人值守执行者必须自行定位并处理空转、阻塞、冷却、反复重启、等待和遗漏，完成查缺补漏。每个问题必须对应具体原因、受影响的用户功能和下一修复动作；同一路径反复失败应改变有源码依据的修复策略，保留部分成果并继续可独立推进的缺口，不得只重复报告或盲目重启、重编译。外部限流或权限限制应如实分类并合理退避，不得绕过限制或伪称已解决。
+- “基本完成”是本阶段复用成果、聚焦补缺的工作定位，不等于所有功能已验证或验收通过。实际残余缺口必须保留并解决；不得通过删除缺口、调整统计、推进队列或编译成功来宣称完整可用。

 - 为了正常推进移植项目工作，用户已授权执行代理在无人值守流程中自主完成必要工作，包括自行修改 Blender 源码、Web/WASM 适配层、协议、Worker、前端入口、构建脚本和任务交接产物；无需为常规实现动作重复请求确认。所有修改仍须遵守本文件其余铁律，并如实记录未验证状态。
 
 - 功能先打通，只有全部功能实现完成后，用户才在使用时验证。全部功能完成是主要工作，中途不进行任何形式的验证，包括测试、回归、冒烟、浏览器验收、类型检查、独立语法检查、上下文检查和证据审计。优先复用本机源码和产物，集中实现真实业务入口；仅为生成所需产物进行增量编译，不把编译成功当作功能完成或验收通过。未验证功能如实记录，不得伪造通过结果。

+
+## 工作方式铁律
+
+- **通过案例，找到缺口，完善程序，稳步实现项目桌面程序到 WEB 移植的完整功能。**
+  每个工作批次必须先落到一个具体的用户案例（桌面 Blender 可复现的操作路径或仓库内已有 fixture/对比案例），在 Chromium 中实走该路径，找出与桌面行为的真实差异；差异必须是用户可见的功能缺口，而不是测试口径、证据簿记或统计口径。找到缺口后直接完善程序实现，再继续下一个案例。禁止用「跑通已有 spec」「补充证据」「重绑覆盖率」替代功能推进。
+
+## 已验证的工作流（后续批次直接复用，不重新摸索）
+
+**一条案例的固定推进顺序**
+
+1. **选案例**：从 `blender-5.2.0/tests/files/` 取真实资产，按"桌面可复现的操作路径"定义，不造合成场景。
+2. **查源码**：先读桌面实现（operator exec、RNA 写路径、DNA 字段），确认桌面语义，再动 Web 侧。
+3. **走真实入口**：Chromium 里用产品自身入口（`blend-file-input`、菜单按钮、`__nativeWorkflowEngine`），不另建第二个 `/browser` 写者。
+4. **定位缺口**：行为差异必须用户可见；区分"我造成的回归"和"既有缺口"，必要时用 A/B（临时禁掉自己那行）判定。
+5. **最小修复**：改到能解释现象的那一处，优先扩展已有函数，不新增并行实现。
+6. **增量构建 + 同步**：`cmake --build build_web_blender6 --target web_engine -j8` → `node tools/web/sync-web-engine-runtime.mjs`；不要手工拷贝产物。
+7. **复测并留证**：结果写入该 case 的 validation，标 `NOT_CLAIMED`；绑定回执不得被复跑覆盖（写目标用 `WBV2_BATCH_PRODUCTION` 之类的可覆盖路径）。
+8. **交接**：continuation 记录断点/已完成/残余/下一动作，status 追加一节。
+
+**探针技法（已验证有效）**
+
+- 驱动 App 自己的 worker：`window.__nativeWorkflowEngine.postMessage({requestId, command})`，按 `requestId + kind==='result'` 收结果；`command()` 等 `__nativeWorkflowRequests/Responses` 增长。
+- 每次打开后等 `main.blender-app` 的 `data-project-id` 与 `engine-status` 含 `SceneIR`，否则会沿用上一个 Main 导致假结论。
+- 点击被原生画布遮挡时先 `exposeWebTools(page)`；保存要靠 `waitForEvent("download")`。
+- 状态判定用 `snapshot` 的语义摘要（剔除 `revision`）与 `saveBlend` 的 SHA-256 摘要分开比较，能区分"数据变了"和"仅序列化抖动"。
+- 判断某分支是否真的执行，用能留痕的副作用（场景名、输出行、打印），不要只看返回 ok。
+- 源码/产物一致性用 `grep -a` 查二进制；`cd` 后相对路径会失效，一律用绝对路径或每批重新 `cd`。
+
+**判定原则**
+
+- 首次调用与后续调用不等价时（一次性运行期初始化），比较"相邻两次重复操作"而不是"前后各一次"。
+- 放宽守卫必须配反向用例：构造真实违规路径，确认仍被拒绝。
+- 编译通过、探针 ok、单 case 通过都只是证据素材，不是验收通过，不给整体完成度。
+
+## 主线铁律（最高优先）
+
+- **唯一主线：把桌面 Blender 的既有功能移植到 Web，让用户能在浏览器里真实操作。** 任何批次的产出都必须落在这条线上：真实的用户入口、真实的原生执行、真实的读回与撤销。
+- **不发散探查。** 不为「查覆盖率」「查声明是否符合」这类台账问题开批次；不连读多看源码只为准确定位一个函数；不为疑似缺口编写大量探针。源码只需读到能改对那一处为止。
+- **每批只做一件事：** 一个用户可见缺口 → 一处原生/前端修复 → 一次编译同步 → 一条有界 Chromium 复测 → 断点落盘。做完即收尾，不顺手扩范围。
+- **方向（2026-11-01 用户书面确认，最高优先）：不做单条失败用例的考古式推进。** 按「盘点已实现能力 → 打包候选 → 全模块实测 → 只修真实阻塞」推进：先枚举现有可用入口、构件与用例并实际跑通，最大化复用已实现功能，尽快形成可验证、可上线的候选；只有实测暴露的真实用户功能阻塞才开修复批次，且一次只改到能解释现象的那一处。
+- **铁律 A — 资产优先，不重复实现。** 先盘清“已接通/已实现”功能清单，再谈缺口；已实现的功能直接复用，不重新走实现流程。队列、任务卡、continuation 只作为“证据来源与资产索引”，不作为推进节拍器。
+- **铁律 B — 阻塞分级，只修真实阻塞。** 失败分三类：真实功能缺陷 / 异步时序 / 测试误操作。只有第一类进入修复，后两类走证据纠正或测试修正，且需证据支撑。同一路径反复失败，先改源码策略，不盲目重跑、重启、重编译。
+- **铁律 C — 打包候选优先于逐例深挖。** 以冻结候选 `build_web_main_desktop/versioning-filepath-20261101` 为基线，按模块打包实测；不以单例通过替代模块结论，也不以单例失败阻塞全量盘点。单例深挖只在“该例阻塞某个模块整体验收”时才做。
+- **铁律 D — 证据必须绑定构件身份。** 正式候选测试绑定绝对路径与构件哈希；开发服务器结果不代替发布验收；不覆盖冻结候选与历史回执。本地 WASM 与原生后端分别记录，互不代替。
+- **铁律 E — 绝对路径 + 最小上下文。** 所有文件、库、构件、日志引用一律绝对路径；读取遵守本文件字节预算，不默认加载完整路线图、parity ledger、源码 inventory、全部历史日志。
+- **铁律 F — 不降标准达成“完成”。** 不删缺口、不缩承诺、不放宽断言、不跳必测项、不调统计。RUN、单例通过、编译成功、源码覆盖统计均不等于整体验收。
+- **缺口按用户能否触发排序。** 用户点得到但无效果 > 用户点不到 > 已接通待验证。台账、能力表、静态清单不与功能实现混在同一批。

+## 16. 模块化开发与 6,620+ 操作符验证规范
+
+本节把“完整移植”落实为可执行的模块合同。完整移植的长期目标是覆盖 Blender 的
+数据模型、操作语义、编辑器工作流和文件生态；发布仍按能力等级逐步交付，不把
+“已经注册”或“Three.js 能显示”误认为 Blender 语义已经完成。当前能力、任务顺序和
+证据以 `docs/EXECUTION_QUEUE.md`、任务 manifest/status 和可复验命令为准。
+
+### 16.1 分层架构和模块边界
+
+所有能力必须落在四层之一，并通过版本化协议连接。浏览器 UI 不直接修改 WASM 堆，
+Three.js 不承担 Blender 语义求值。
+
+| 层 | 责任 | 首批模块 | 权威状态 |
+| --- | --- | --- | --- |
+| 核心层 | DNA/RNA 对齐、数据块生命周期、数学库、Main、revision 和 depsgraph | `core`、`data`、`math`、`depsgraph` | Blender WASM Main |
+| 操作层 | 面向用户的 operator、共享算法、参数校验、撤销/重做 | `mesh`、`object`、`material`、`animation`、`render` | EngineWorker |
+| UI 层 | Workspace/Area/Region/Editor、Context、Keymap、属性面板和视口交互 | `viewport`、`outliner`、`properties`、`timeline`、`node-editor` | React UI state + Engine revision |
+| 系统层 | `.blend` 文件、导入导出、Worker、插件能力声明、缓存、性能和安全 | `file-io`、`storage`、`workers`、`plugin`、`performance` | StorageWorker/manifest |
+
+每个模块必须声明 `moduleId`、owner、输入/输出 schema、依赖模块、生产入口、测试入口、
+资源预算和回滚点。模块只通过 `EngineClient`、SceneIR 或协议类型访问其他模块；禁止
+在 React 组件中复制 Blender 数据结构，禁止在 checker 中构造生产结果。
+
+推荐的实现分工如下：TypeScript 负责协议、注册表、UI 和测试编排；Blender C/C++
+以 WASM 负责 DNA/RNA、Main、依赖图和需要保持语义一致的算法；Three.js 只负责
+SceneIR 的实时渲染；React（或等价的 Vue 层）负责 Blender 风格的编辑器组合和输入路由。
+
+### 16.2 操作符注册和统一执行上下文
+
+操作符以稳定 ID 注册，按模块和类别批量装载。一个 operator 不是一个独立生产任务，
+而是共享算法引擎的参数化声明。建议的最小模型如下：
+
+```ts
+type OperatorDefinition<Args, Result> = {
+  id: string;                         // e.g. "mesh.extrude_region"
+  moduleId: string;
+  category: "mesh" | "object" | "material" | "animation" | "render";
+  dependsOn: string[];                // operator or module IDs
+  poll(ctx: OperatorContext, args: Args): PollResult;
+  execute(ctx: OperatorContext, args: Args): Result;
+  serialize?(result: Result): SceneDelta;
+};
+
+type OperatorContext = {
+  main: MainHandle;
+  sceneRevision: number;
+  sceneId: string;
+  mode: "OBJECT" | "EDIT" | "POSE" | "SCULPT";
+  selection: StableId[];
+  depsgraph: DepsgraphSnapshot;
+  budget: { timeMs: number; memoryBytes: number };
+  signal: AbortSignal;
+};
+```
+
+注册流程固定为：加载模块 manifest -> 校验 schema/hash -> 按依赖拓扑排序 -> 批量注册
+定义 -> 冻结 registry snapshot -> 执行命令。`poll` 只做上下文和参数检查；`execute`
+只能通过 `MainHandle` 提交事务，返回新的 revision、SceneDelta 和结构化 report。依赖
+缺失、schema 不兼容、取消、超时、超预算和重复提交都必须 fail closed，不能修改已提交
+的 Main 或 revision。
+
+共享算法应通过参数配置覆盖操作符变体，例如 mesh 的选择集、法线、拓扑和属性保护
+策略由一个 mesh transaction engine 实现，`extrude`、`inset`、`bevel` 等只提供不同
+参数和上下文约束。只有当操作符具有不可共享的 Blender 语义时，才允许新增专用 engine，
+并在模块报告中说明原因。
+
+### 16.3 批量开发协议
+
+开发以模块为最小交付单元，禁止按单个操作符拆分生产任务或逐条手工提交。每个模块
+按以下顺序完成：
+
+1. **契约门**：冻结 operator schema、错误码、稳定 ID、依赖、预算、revision 和 Main 回滚规则。
+2. **生产门**：实现共享算法、模块 registry、EngineWorker 入口和 React/Three.js 所需的最小接线。
+3. **负例门**：覆盖 malformed、unsupported、poll 失败、取消、迟到、重复、超预算和 hash drift；失败时保持 `in_progress`。
+4. **批量门**：在同一份不可变 catalog 快照上运行该模块的全部映射 cases，并按确定性 shard 分片。
+5. **证据门**：生成 desktop/WASM 对照、save/reopen、报告、artifact SHA-256、manifest、status 和回滚说明。
+
+模块合并前必须运行受影响模块的全量 matrix；模块依赖闭包变化时，扩展到依赖模块。生产
+提交可以一次包含多个 operator 定义，但只能对应一个模块行为或一个独立证据变化，避免
+把“注册完成”提前当成“能力完成”。
+
+### 16.4 6,620+ 操作符验证矩阵
+
+操作符目录从固定版本的 Blender 文档/RNA/源码生成，并写入带 source hash 的机器 catalog。
+目录规模以 pinned catalog 为准，当前目标是覆盖 **6,620+** 条操作符记录；文档中的数量
+不是可手工修改的完成度指标。每条记录至少包含：
+
+- `operatorId`、`moduleId`、Blender 版本、来源文件和 `behaviorClass`；
+- 所需 `poll` context、参数 schema、默认值、前置数据块和能力等级；
+- 正例 fixture、边界输入、随机种子和预期 invariants；
+- desktop/WASM runner、save/reopen 策略、资源预算和已知阻断原因。
+
+每个模块 runner 对目录执行三类用例：
+
+| 用例 | 目的 | 最小断言 |
+| --- | --- | --- |
+| 基础用例 | 证明正常上下文和典型参数 | operator 返回成功，Main/revision/SceneIR 改变符合 schema |
+| 边界用例 | 证明空选择、退化拓扑、缺失引用、非法参数和预算边界 | 稳定错误码，旧 Main、revision 和文件保持不变 |
+| 随机用例 | 发现参数组合和依赖顺序问题 | 固定 seed 可重放；不变量、内存和时间预算不漂移 |
+
+正例必须比较 Blender desktop golden 与 WASM/Main 结果，并在需要时保存、关闭、重新打开
+后再次比较。Three.js 的像素或对象存在性只能作为呈现证据，不能替代 Blender 语义结果。
+不支持或证据不足的 operator 保持 `BLOCKED`/`METADATA_ONLY`，不得伪造 `PASS`。
+
+### 16.5 Worker 并行、缓存和增量验证
+
+批量验证由 Node 编排器生成确定性 shard，并在 Chromium-only 约束下将独立 case 分发到
+Web Workers。每个 shard 使用独立的临时目录和 WASM 实例；worker 返回结构化结果，不共享
+可变 Main。聚合器按 `operatorId` 排序后生成报告，保证并行度变化不会改变 artifact hash。
+
+缓存键至少包括：Blender/WASM 构件 hash、catalog source hash、module registry snapshot、
+fixture hash、runner 版本、浏览器能力和随机 seed。缓存命中只能跳过完全相同的 case；
+schema、算法、依赖、fixture 或浏览器能力变化时必须失效。
+
+增量验证按“变更模块 + 依赖闭包 + 受影响 catalog 行”选择 case；模块未变化且缓存有效的
+行可以复用，但每次模块合并仍要执行一次全量模块 matrix。报告应同时给出总量、执行量、
+缓存命中量、`PASS`、`FAIL`、`BLOCKED`、`RETAINED_NEGATIVE`、耗时、峰值内存和覆盖率，
+不能只输出一个百分比。
+
+### 16.6 完成门和报告格式
+
+模块只有在以下条件全部满足时才可进入 `done`：
+
+1. registry snapshot、schema hash 和 catalog source hash 稳定。
+2. desktop/WASM 正例、边界/随机负例和 save/reopen 结果齐全。
+3. Worker shard 与串行重跑结果一致，缓存命中不会掩盖失败。
+4. Main revision、文件 hash、SceneIR invariants 和资源预算均无未解释漂移。
+5. 报告、manifest、status 和聚焦命令可复验；失败或环境缺失时保持 `in_progress`/`blocked`。
+
+建议的聚合报告字段：
+
+```json
+{
+  "schemaVersion": 1,
+  "moduleId": "mesh",
+  "catalogSourceHash": "sha256:...",
+  "registryHash": "sha256:...",
+  "counts": { "total": 0, "executed": 0, "cached": 0, "pass": 0, "fail": 0, "blocked": 0 },
+  "coverage": { "registered": 0, "withFixture": 0, "withDesktopGolden": 0 },
+  "cases": [],
+  "artifacts": []
+}
+```
+
+报告只描述实际运行结果；不能通过修改 Markdown checkbox、手工推进 `nextTask` 或删除
+失败 case 来提高覆盖率。任务交接继续使用 `node tools/web/check-task-context.mjs --task
+<task-id> --write`，并遵守当前队列的最小上下文和 Chromium 验收规则。

+当前基线记录 6,900 条总记录、6,618 条 pending，后续以 hash-bound inventory 的精确值
+为准。生产、验证和交接分成三层：
+
+```text
+module (production boundary) -> capability/command (shared primitive)
+                              -> operator case (coverage row)
+```
+
+| 层 | 责任 | 是否创建独立 production task | 交付物 |
+| --- | --- | --- | --- |
+| 模块 | 一组共享 Main/command/context/资源事务的代码边界 | 是，每个模块一个或少量任务 | 生产代码、模块契约、代表性 fixture |
+| capability/command | 可复用的用户可见行为和错误/回滚语义 | 否，作为模块内共享原语 | API、revision/Main mutation、undo/save 语义 |
+| operator case | 从 Blender inventory 得到的参数、context 和预期结果 | 否，只是数据行 | 批量 runner 结果、状态和 artifact hash |
+
+模块边界按代码所有权、事务边界和发布风险划分，而不是按 operator 数量划分。若两个
+operator 仅参数不同且共享 command、context、回滚和持久化路径，必须归入同一模块；若
+它们需要不同的 Main writer、资源权限或 Chromium workflow，才拆成不同模块。一个模块
+仍然过大时按独立 contract/API 或可回滚边界拆分，不按清单行号切分。
+
+旧方式和新方式的对应关系固定如下：
+
+| 旧方式 | 新方式 |
+| --- | --- |
+| 一个 operator 一个实现任务 | 一个模块实现共享原语，operator 只登记 `operatorId -> moduleId` |
+| 每个 operator 单独启动桌面/WASM/重开测试 | 模块完成后由同一 runner 分片执行全量 operator matrix |
+| 每个 gap 单独提交和推进 parent | 模块生产变更与一次模块 manifest 提交；coverage report 可由生成器更新 |
+| `CANCELLED`/metadata-only 也容易被算作完成 | 每个 case 明确 `positive`、`negative`、`mainMutation` 和 `parityLevel`，负例不升级能力 |
+
+每个 operator case 至少包含 `operatorId`、`moduleId`、`behaviorClass`、`context`、
+`fixtureParams`、desktop 预期、WASM 实际、`revisionDelta`、`mainMutation`、
+`saveReopen`、`negativeStatus` 和输入/输出 hash。case 状态限定为
+`UNMAPPED`、`READY`、`PASS`、`FAIL`、`BLOCKED`、`RETAINED_NEGATIVE`、`NOT_APPLICABLE`；
+只有正向结果、`mainMutation=CHANGED` 且达到 L2-L5 的 case 才能计入 capability 覆盖。
+
+模块执行固定为五步：
+
+1. **契约和小样本门**：冻结模块 API、错误码、预算和回滚语义，先用最小正/负/重开
+   样本证明 runner 与 desktop oracle 接线正确。
+2. **模块实现门**：完成共享 production code；代表性 cases 必须在 desktop 和 WASM
+   得到等价正向结果，并通过 Chromium workflow（适用时）。
+3. **全量 operator matrix 门**：模块代码冻结后，一次生成并分片运行该模块映射的全部
+   operator cases；禁止手工逐条执行或为某个 operator 增加 checker 分支。分片只改变
+   执行顺序，不改变 case、输入、期望或汇总 hash。
+4. **全域回归门**：模块候选合并前，用同一套数据驱动 runner 分片执行全量 operator
+   catalog（含未映射和历史负例），与 hash-bound baseline 比较；不得出现既有 `PASS`
+   变为 `FAIL`、新产生未审查的 `BLOCKED` 或 Main/revision 退化。该门是一次批量回归，
+   不是为每条 operator 建立新任务。
+5. **模块交接门**：汇总 `total/pass/fail/blocked/retainedNegative`、每片退出码、
+   runner/catalog/source hash 和 manifest；任何失败、预算超限、hash drift 或正向
+   语义缺失都保持模块 `in_progress`，不推进 successor。
+
+验证频率也分层：每次代码变更运行小样本和受影响 cases；模块完成前必须运行一次全量
+matrix；合并后按固定 shard 在 CI/nightly 重跑全量 matrix。这样减少启动和交接次数，
+同时保留每个 operator 的可追溯结果。

+The production unit is a module-backed capability workflow, not an individual Blender
+operator or RNA field. A module owns a coherent code, transaction, and rollback boundary;
+its capability commands are shared primitives, and its operator inventory rows are
+data-driven coverage cases. A single module task may therefore cover hundreds of related
+operators without creating hundreds of production tasks.
+
+The required relationship is:
+
+```text
+module task -> capability/command -> operator case matrix
+```
+
+An operator ID is never a queue pointer. It maps to exactly one primary module and records
+its context, parameters, desktop oracle, expected mutation, negative boundary, persistence
+expectation, and result status. The historical 6,620+ figure is a catalog-scale estimate,
+not a promise to run 6,620 hand-authored commands; the current inventory has its own exact
+total/pending counts and SHA, recorded in the module manifest.
 
 Every capability task must state its parity level, positive mutation, negative boundary,
 save/reopen behavior, undo/redo behavior, resource budget, and Chromium receipt. A
 `CANCELLED`, `UNSUPPORTED`, metadata-only, snapshot-only, or external-resource result is
 coverage evidence, never a positive feature claim.
 
+### Module completion gate
+
+Module work has a fast feedback loop and a mandatory batch gate:
+
+1. Freeze the module contract and run a small representative positive/negative/reopen set.
+2. Implement the shared production path and prove a real desktop/WASM Main mutation.
+3. Freeze the source and run every mapped operator case through one versioned runner. Shards
+   may run in parallel, but use the same catalog snapshot and deterministic inputs.
+4. Before merge, run the full operator catalog as a sharded regression suite and compare it
+   with the hash-bound baseline. Existing passes may not regress, and new failures/blocked
+   cases require review; unsupported or retained-negative baselines are not treated as passes.
+5. Publish one aggregate manifest containing case counts, shard exit codes, catalog/source
+   hashes, and links to per-case evidence. Any failed, blocked, budget, or hash-drift case
+   keeps the module in progress.
+
+Per-change checks may run only affected cases plus the representative set. A module cannot
+be marked complete until the full matrix has passed; the same matrix is then a scheduled
+regression suite. No operator-specific checker branch, queue slot, or production commit is
+created when the behavior uses an existing module primitive.

+repeated generic markers, and build-only smoke are not feature completion.
+The historical 6,900-entry inventory remains read-only. The current source-derived

+estimate. Units remain unverified until explicit behavior evidence binds them.
+
+## Project completion audit
+
+The current migration epoch is a verified capability slice, not full Blender parity.
+It contains 38 completed source-backed function modules plus the bridge/root and
+successor-authorization tasks; the module plan is terminal at `WBV2-P1131-001`.
+The historical 15-family inventory has 281 legacy receipts and zero full-family parity claims;
+the dynamic source ledger is conservative until each unit is explicitly mapped. Pending volume is
+concentrated in UI (3,930), Media I/O (585), Nodes (543), Mesh Editing (431), Rig
+Animation (375), Object Operations (316) and Simulation (155). Follow-up waves must
+select one source-backed family at a time, reuse existing receipts by hash, and require
+the same Main/Worker/frontend, negative, recovery and Chromium gates. The next
+checkpoint is the first explicitly authorized corrective or uncovered-family task after
+`WBV2-P1130-001`; do not infer full-family parity from representative slices.

+# WBV2 next migration waves
+
+Date: 2026-09-01
+
+The current function-module epoch ends at `WBV2-P1130-001`. It contains 37 completed source-backed modules plus the bridge/root and successor-authorization tasks. It is a verified migration slice, not full Blender parity: the immutable inventory remains 6900 total and effective `290/6609`.
+
+## Completed and reusable
+
+- Core scene, mesh, material, non-mesh, nodes, asset, sculpt, editor, object, compositor, audio/particle and rig modules: reuse their receipts by SHA-256.
+- GLB mesh/non-mesh roundtrip dependency repair: `WBV2-P1123-000`.
+- Historical M12 drift audit: `WBV2-P1124-000`; 84 entries across 43 paths are `BLOCKED_SOURCE_LOST`, with old manifests untouched.
+- Geometry Nodes allowlist/Main persistence and typed unsupported mapping: `WBV2-P1125-000`.
+- Grease Pencil viewport selection/marquee on main and Offscreen Chromium: `WBV2-P1126-000`.
+- Tracking Mask reader/interaction: `WBV2-P1127-000`.
+- ffmpeg.wasm MOVIE probe/proxy fallback: `WBV2-P1128-000`; local core resources are hash-bound and upstream source is checked out at `f876f907c7e9b9bf51d4ed0b913a855a63ae63fc`.
+- Core Scene Graph compositor/performance/sampling settings: `WBV2-P1129-001`; reused P65/P66/P67 source receipts and added one aggregate Chromium Main transaction receipt.
+- UI Editor View2D state: `WBV2-P1130-001`; dedicated adapter preserves Graph/Dope Sheet `cur` and pixel `mask` without changing the P1102 parser.
+- Web-safe Sound/Speaker/ParticleSettings retention uses authoritative Main Scene IDProperty; desktop Audaspace stays disabled.
+
+## Ordered follow-up waves
+
+1. `IO_LIBRARY_HASH_REHYDRATION`: use `M12-manifest-sha-drift.json` and current observed hashes to produce corrective evidence; recover original bytes only from trusted cache. Never re-sign old manifests.
+2. `UI_EDITOR_FAMILY`: split the 3930 UI rows by editor/workspace/region behavior, reusing existing Main reader/context and keyboard/layout evidence without duplicate E2E.
+3. `MEDIA_IO_FAMILY`: extend image/audio/video routes around the ffmpeg.wasm Worker; add a new receipt for each distinct codec/container contract.
+4. `NODES_SIMULATION_FAMILY`: extend only for a new node family or simulation lifecycle with distinct Main mutation and recovery evidence.
+5. `MESH_EDITING_FAMILY`: select remaining UV/material-slot/topology rows not represented by existing aggregate fixtures.
+6. `OTHER_OPERATORS_CORE_SCENE`: cluster remaining operators by Main ownership and save/reopen semantics, then run source-backed modules only.
+
+## Execution shape for the remaining inventory
+
+The 6,609 effective pending rows are a coverage ledger, not 6,609 independent
+implementations. The implementation unit remains:
+
+```text
+owner family -> source-backed module -> shared command/reader -> operator case matrix
+```
+
+For every new module, use this bounded sequence:
+
+1. Generate a deterministic family slice from the immutable P0 inventory. Each row must
+   have one primary module, one behavior marker, an implementation class, and a source
+   path. Existing receipts are linked by SHA-256 instead of reimplemented.
+2. Freeze a small positive/negative/reopen contract. Implement the real Blender Main,
+   WebEngine, WASM ABI, Worker/protocol and frontend path once for that behavior.
+3. Run the mapped case matrix in shards against the same catalog/source snapshot. Shards
+   may run concurrently inside a module, but queue handoff remains serial and follows the
+   parent manifest only.
+4. Aggregate source hashes, positive and negative counts, no-mutation/recovery evidence,
+   undo/redo, save/reopen, deterministic replay and Chromium results into one receipt.
+   Only then may an effective-ledger overlay add coverage; the original inventory and
+   historical manifests stay unchanged.
+
+The recommended batching is by shared ownership, not by operator name:
+
+| Batch | Module slices | Planning scope | Required reuse |
+| --- | --- | ---: | --- |
+| Provenance gate | `IO_LIBRARY_HASH_REHYDRATION` | 84 drift entries / 43 paths | M12 corrective report; trusted cache only; never re-sign |
+| UI | editor/workspace/region context, input, layout persistence | 3,930 | `UI_EDITOR`, `UI_INPUT_INTERACTION`, Main context readers |
+| Media | image/audio/video container and codec contracts | 585 | `SEQUENCER_MOVIE_CODEC`, local ffmpeg.wasm Worker, media retention |
+| Nodes | node families, sockets, simulation lifecycle | 543 | `NODES_GRAPH`, `NODES_SIMULATION`, typed unsupported mapping |
+| Mesh | UV, material slots, topology and edit history | 431 | `SCENE_OBJECT_MESH`, mesh transaction/history fixtures |
+| Rig/Object | remaining rig, constraint, object ownership behaviors | 691 | `RIG_ANIMATION`, `OBJECT_OPERATIONS`, depsgraph recovery |
+| Simulation | non-node physics/cache lifecycles | 155 | `SIMULATION_CACHE`, `ENGINE_RUNTIME` |
+| Material/Render | unrepresented material and render settings | 125 | `SHADER_MATERIAL`, `RENDER_PIPELINE` |
+| Sculpt/Paint | remaining stroke, mask and paint data paths | 117 | `SCULPT_PAINT`, `PAINT_STROKE` |
+| Other/Core | residual operators and core Scene graph ownership | 169 | Main ID ownership, save/reopen and explicit unsupported routing |
+
+Planning scopes overlap where one legacy row belongs to more than one observable behavior;
+they must not be summed to claim more than the 6,609 effective pending rows. The provenance
+gate is a separate corrective lane: it must be recorded before any completion overlay is
+changed, but a source-lost result does not block an unrelated source-backed module once that
+status is explicit. Every successor still requires its own source-backed slice and parent
+manifest authorization.
+
+## Per-family exit gates
+
+A family remains `in_progress` until every selected module has all of the following:
+
+- stable source, protocol, Worker/frontend and fixture hashes;
+- a real Main mutation or an exact Main reader/context result;
+- positive, malformed/unsupported and no-mutation cases;
+- undo/redo where the behavior mutates state, plus save/reopen and deterministic replay;
+- Chromium-only production evidence and an aggregate manifest with shard exit codes;
+- an explicit `VERIFIED`, `UNSUPPORTED`, `ENVIRONMENT_UNAVAILABLE`, `HASH_DRIFT` or
+  `SOURCE_LOST` result for every mapped case.
+
+Failure, hash drift, missing source, budget exhaustion or browser unavailability stops the
+current module and preserves the parent `nextTask`. It never reduces the pending count and
+never creates a corrective duplicate of an existing receipt.
+
+## Progress accounting
+
+Report three numbers independently after each handoff: source-backed modules completed,
+effective inventory coverage, and legacy regression coverage. The current baseline is
+`37` modules / `41` module tasks, `290/6609` effective, and `281/6618` legacy. A module
+receipt may increase effective coverage only when its case-to-inventory mapping is
+hash-bound; implementation or build success alone does not.
+
+## Verification rules
+
+- Chromium only; use an isolated `WEB_TEST_PORT` for every Playwright lane.
+- Read the queue, print fresh context, and run context checks before edits.
+- Do not rerun a completed module merely to refresh logs.
+- Keep unsupported, environment-unavailable, hash-drift and source-lost states explicit.
+- A module advances only after source hashes, positive/negative/recovery evidence, save/reopen, deterministic replay and aggregate manifest pass.
+- The 6900 inventory and historical manifest meaning remain immutable.
+
+## External scheduler checkpoint
+
+`print-wbv2-live-status.mjs` still reports the old scheduler/guardian/supervisor checkpoint blocked at `P594`. That state is unrelated to the local authoritative capability queue and remains read-only until an explicit scheduler recovery task is authorized.

+# Camera 原生景深吸管
+- 主目标仍为完整移植及最终验证验收；任务in_progress，本段implemented_unverified；validation=NOT_RUN、acceptance=NOT_CLAIMED，未部署。
+- DOF面板Pick Focus Distance经现有gpuUIInvoke/BPy/WM调用原生UI_OT_eyedropper_depth；Web显式Camera RNA目标用临时context提供，native poll/init要求可编辑Camera、DOF启用、无focus_object、可编辑距离及匹配session UID。
+- 复用原深度采样/拖动平均/确认/取消/undo代码，不用JS或Three计算深度；调用前取实际native mode，打开/聚焦既有原生3D画布。更广的WM异步终态反馈/popup归属仍由原缺口保留。
+- 两次必要构件生成失败分别定位到RNA_RUNTIME接口和5.2指针形式，已据源码修复；最终native build及打包exit0，后续live-mode前端候选复用该原生对。日志全部保留，未执行独立语法/类型/测试/浏览器或验收命令。

+- 残余：GPU取样、运动目标、确认/取消、undo/redo/save/reopen及Chromium行为未验证；shader绝对/目录外来源映射、WM终态/popup及所有原模块残余保留。源码unit增量0，其余inventory未审计，不报整体百分比。
+- continuationNotes：下一轮消费最终候选后续shader显式来源映射或G01-F3-LOCAL-INVOKE的WM异步终态，不重做已接线吸管；健康worker完成前不重启，传输重连不计源码进展。完整目标保持active。
+- 4246交接边界：process记录exit0、reason=worker_source_progress_deadline、changedProductionFiles仅App.tsx、无result.json；因此只绑定该真实源码观测与已hash绑定candidate，foreground请求sourceCycles=[4246]，不把worker结束当功能完成。
+- 父调度已消费final候选：state显示applicationCandidate.cycle=4246、path=camera-depth-picker-final-20261009/candidate.json，pendingSourceCycles=[]；同manifest更新候选去重缺陷已修复并安全重载服务。仍为implemented_unverified，未进入验证/验收。
+- 追加修复：App在GPU invoke只收到错误且没有Scene时，现按Main未知/可重试处理，不再访问空的`result.scene.snapshot`导致错误反馈链二次崩溃；最终前端候选为camera-depth-picker-final-202609，待4246真实source handoff消费。4245无源码进展，不计入新覆盖。

+- manifest随后补绑web/protocol/web-engine.ts的modalActive协议哈希，确保交接范围包含协议、Worker、Client和App全部实际变更；不改变候选或验收状态。
+- `camera-depth-picker-modal-frame-20261009` 已生成但当前state仍指向已消费的 `camera-depth-picker-modal-20261009`；由于服务尚未观测到新的Worker source cycle，暂不伪造消费或清pending，待真实changedProductionFiles后再交接。
+- 最新4257已真实观测App.tsx与WasmGPUCanvas.tsx修改，当前worker仍存活且尚无终态process；modal-canvas候选待该轮安全交接，不提前清pending或推进队列。
+- 父调度已完成收敛：state显示applicationCandidate.cycle=4257、path=camera-depth-picker-modal-canvas-20261009/candidate.json，pendingSourceCycles=[]；modal帧回调候选已安全消费。
+- 最新state已更新为applicationCandidate.cycle=4251、path=camera-depth-picker-modal-frame-20261009/candidate.json，pendingSourceCycles=[]；父调度已在安全边界接收frame modalActive候选，前述等待说明已闭合。
+- 更正：随后父调度已将applicationCandidate更新为cycle=4257、path=camera-depth-picker-modal-canvas-20261009/candidate.json；上条frame路径仅为中间状态，不代表当前候选。4260当前为provider_reconnecting，App修改已观测但尚未形成终态交接。

+Production changes: `web/app/src/app/ModifierParameterField.tsx`, `web/app/src/app/WasmEditorContext.tsx`.

+The existing native path remains authoritative: RNA metadata supplies minimum/maximum and `web_engine_blend_main_set_modifier_parameters` validates and updates the modifier. No JS geometry or duplicate setter was introduced.

+continuationNotes：修复autosave仅在nativeCanvasReady期间取消scheduler，detach后重排checkpoint；clean5秒post-open Chromium检查nativeDisplay acknowledged且无AUTOSAVE_FAILED/NATIVE_GESTURE_ACTIVE。下一步真实拖拽/模态取消与持久checkpoint矩阵；Acceptance NOT_CLAIMED。
+continuationNotes：新增桌面Modeling/Scripting Ctrl+Space矩阵通过；autosave scheduler在nativeCanvasReady期间取消、detach后恢复，typecheck/package通过。Web pointer与gizmo query仍已观察无selection错误，但完整拖拽/模态取消与存储checkpoint尚未验收；runner/preview停止，Acceptance NOT_CLAIMED。
+continuationNotes：autosave修复已typecheck/package通过，但默认native canvas旧用例和两次未等待fixture的Web脚本均不能证明dirty→saved；将残余标记为未验收而非通过。下一步显式Web业务fixture加载→workflow AVAILABLE→Add CUBE→dirty/saved；preview/runner停止，Acceptance NOT_CLAIMED。
+continuationNotes：显式Web业务fixture加载到AVAILABLE，但Add CUBE action在当前wasm-source-workspace渲染器中隐藏，不能把autosave断言误报为通过；需先修复可见业务action surface再测dirty→saved。preview/runner停止，Acceptance NOT_CLAIMED。
+continuationNotes：Add CUBE不可见根因确认为legacy-quick-toolbar默认display:none且仅quickTools=true显示；Web业务模式非native canvas现显示已有原生业务操作栏，native canvas布局不变。下一步重包并跑显式fixture Web dirty→saved autosave；contextReference=validation-20261014/autosave-native-gesture-web-mode-5276.json；Acceptance NOT_CLAIMED。
+continuationNotes：显式fixture→workflow AVAILABLE→Web business→可见Add CUBE后dirty状态正确变为未保存，等待2.5s无AUTOSAVE_FAILED/NATIVE_GESTURE_ACTIVE；状态保持未保存符合persistRecoveryCheckpoint不提交dirty语义。下一步用storage worker/OPFS直接读回checkpoint，随后完整恢复矩阵；preview/runner停止，Acceptance NOT_CLAIMED。
+continuationNotes：显式Web业务fixture+Add CUBE后dirty=未保存且无AUTOSAVE_FAILED/NATIVE_GESTURE_ACTIVE；直接storage worker读回在Vite preview因/src/workers/storage.worker.ts未转译启动失败，故checkpoint持久化不宣称通过。下一步用正式应用服务路由执行storage proof，随后恢复矩阵；preview/runner停止，Acceptance NOT_CLAIMED。
+continuationNotes：2026-10-17 已用包含轴线、StudioLight、Workbench/gizmo 修复的 Chromium 候选完成工具栏图标资源/绘制路径实证：原生画布 acknowledged、1440x900 frame、顶部/左侧工具栏及 Properties 图标可见，icon/shader console errors=0；证据=validation-20261014/toolbar-icons-runtime-20261017.json，截图=toolbar-icons-runtime-20261017.png。旧 polygon_smooth 阻塞交接已过期并在 workbench-transparent-view-progress.json 更正。下一直接动作：继续 Modeling/Scripting 视觉与模态交互矩阵，再做正式应用服务的 storage checkpoint/recovery proof；Validation PARTIAL_FAILED，Acceptance NOT_CLAIMED，runner/preview 已停止。

+- 2026-10-26 B3 read-error symmetry: current v2 candidate passes minimal and ABB production reader-error/partial-retention cases with unchanged Main/history; evidence retained under `validation-20261026-b3-transfer-ui/current-error-v2`. Native-drop owner settle/prompt remains the only active transfer interaction residual.
+- 2026-10-26 B3 owner trace source binding: `wm_window_web_scene_changed` in `wm_window.cc:3829-3844` advances the web input epoch during post-open scene propagation; the drop handler observes owner 1→2 before type-9. Stale-owner cancellation remains intentional; next action is an explicit owner-stable barrier.
+- 2026-10-26 B3 owner trace: native-drop staging observes ownerGeneration 1 on initial focus frame, then 2 on the post-open scene/input frame; upload reaches Worker but stale owner protection prevents type-9 dispatch. This is retained as the precise residual; no owner-loss bypass claimed.
+- 2026-10-26 B3 owner-stable v2: drop handler captures owner after canvas focus; new candidate `build_web_main_desktop/b3-transfer-drop-owner-stable-v2-20261026/candidate.json` passes all four current-bound transfer file/folder cases. Native-drop positive remains owner-settle sensitive and prompt confirmation stays unclaimed; evaluator PARTIAL_BLOCKED/30.1 with 18 blockers.
+- 2026-10-26 B3 native-drop follow-up: transfer remains 4/4 current-bound PASS after pointer-move focus stabilization. Native-drop v7 cancellation/type-9 receipts remain historical partial evidence; current reruns exposed owner-generation settling and prompt-key delivery instability, so prompt confirmation/UndoRedo/SaveReopen stay unclaimed.
+- 2026-10-26 B3 transfer/drop v7 update: current pointer-move boundary closes minimal/ABB file and folder-restore transfer gates (4/4 current-bound). Native drop minimal/ABB cancellation and type-9 delivery remain PASS; unsaved prompt confirmation, UndoRedo and SaveReopen remain pending. Evaluator remains PARTIAL_BLOCKED/30.1 with 18 blockers; B3 in_progress/NOT_CLAIMED.

+- Scheduler throughput tuning: recent turns spent 140–442s with 20–51 source reads and no production changes. Defaults now bound source investigation at 12 reads/210 active seconds, idle at 300s, and source progress at 300s; minimum read floor remains 8. This changes rotation speed only, preserves pending/old candidates, and does not claim feature completion.

+- 2026-10-24 B3 F3 Server Operator cancellation: `App.tsx` now creates an AbortController for SERVER_NATIVE F3 execution, displays Cancel, and keeps AbortError separate from COMMAND_FAILED diagnostics; `WebEngineClient.invokeFeatureRoute` forwards the signal into `submitServerOperatorJob`, allowing provider cleanup and no late Main/success publication. UI hash `fc81ba0e44f408659dcb9fea373a2dac5fd5919dc3118e426e46a9eafc681df3`; engine hash `3c21dc3a2260f5b62cea8a07c5376309ddf40125782c04262d9560e95c828af3`; report/manifest `tests/golden/WBV2-P1424-001/b3-f3-server-cancel-20261024.md` and `b3-f3-server-cancel-20261024-manifest.json`.

+- 2026-10-24 B3 F3 schema cancellation: `WebEngineClient.describeServerOperator` now accepts and forwards the same AbortSignal used by `invokeFeatureRoute`, so first-use schema fetches can cancel before job allocation; cached-schema submission retains provider cleanup and no-late-publication behavior.

Validation NOT_RUN, acceptance NOT_CLAIMED; Chromium/Xvfb and all B3 runtime/readback gates remain pending.
+- 2026-10-24 B3 F3 cancellation isolation: `App.tsx` now limits `web-engine-native-modal-cancel` broadcasts to Desktop/local native cancellation; SERVER_NATIVE Escape cancellation only aborts its own request, preventing interference with an unrelated viewport modal. UI hash `7e6bbd6c65c2e359a8755d18e1eaf863d2eaf9b1a7958b727f27008cc44182ec`; report/manifest `tests/golden/WBV2-P1424-001/b3-f3-cancel-modal-isolation-20261024.md` and `b3-f3-cancel-modal-isolation-20261024-manifest.json`.

+- 2026-10-24 B3 OBJ browser-equivalent correction: direct `WM_OT_obj_import`/`WM_OT_obj_export` calls remain blocked by Blender's `WM_operator_winactive`, but the catalog now registers them as `BROWSER_EQUIVALENT` OPEN/SAVE routes so F3 invokes the existing browser-owned file workflows.

Validation NOT_RUN, acceptance NOT_CLAIMED; Chromium/Xvfb, F3 action and OBJ runtime evidence plus remaining B3 gates remain pending.
+- 2026-10-24 B3 schema cancel cleanup: `server-operator-job-server.mjs` now propagates HTTP request `aborted` to the bounded describe child and preserves normal workspace cleanup, so cancelling a first-use F3 schema request cannot leave the provider process running to timeout.

+- 2026-10-24 B3 submit disconnect cleanup: `server-operator-job-server.mjs` now listens for submit request `aborted`; if the client disconnects before receiving 202, the provider publishes terminal `CANCELLED`, kills the bounded process tree and retains no late result. Provider hash `c33af143552b716d71d55f545c0d1fb420245270e30b14d207d9a62ed2587f81`; report/manifest `tests/golden/WBV2-P1424-001/b3-server-submit-abort-cleanup-20261024.md` and `b3-server-submit-abort-cleanup-20261024-manifest.json`.

+- 2026-10-25 B3 Save Copy ownership: corrected the Web menu/dialog previously bound to Save As. Copy-only serialization uses the existing native writer, frame pause, SAVE lock and download while bypassing project metadata commit; original project/name, committed hash/revision and dirty state remain current. Autosave is rearmed after copy completion/failure. App source SHA-256 908e6f34afd903b5b99c1f307cafa65657701d01a749e1e56196b753f13bf5d5.

+- 2026-10-29 B3 ExternalImage 自动保存黑图：定位为 WASM 侧 PNG 编码在 libpng `tEXt: invalid keyword` 处中止（OIIO 把每条字符串 ImageSpec 属性写成文本块，键名净化后无可保留字节即 png_error），导致无 IDAT、`memory save for pack error`、自动保存不含像素、恢复回落磁盘黑图；桌面控制组同一资产 exit=0 通过。已按 libpng 自身的可保留字节规则（33-126 或 >=161）在 `imb_create_write_spec` 增加 PNG-only 守卫，丢弃不可用键名而不是丢掉整幅图像（openimageio_support.cc:499-510，before 6cf1ff47… after ffbbe5ad…，+12/-0）。增量构建 exit=0、0 error、补丁文件 0 warning，产物 web_engine.wasm f856f4c6…；候选 build_web_main_desktop/b3-png-keyword-guard-20261029 candidate.json 7a8c0ce8…。功能测试 NOT_RUN、acceptance NOT_CLAIMED，单案例采集已发起但结果不构成通过。
+- 2026-10-30 B3 ExternalImage 黑图更正：上一批的 PNG 键名守卫（openimageio_support.cc:499-510）无效并已回退到基线 6cf1ff47…；该守卫随行的 wasm f856f4c6… 实际已上产物，错误依旧，证明假设错误。重新取证后定位为两条打包路径的差别：`image_memorypack_imbuf`（普通打包，image.cc:1486-1491）无重试，而上一批只给 `image_memorypack_imbuf_for_autosave` 加了重试；`G_FILE_AUTOPACK` 下 `save_as_mainfile` 走 wm_files.cc:2249 → `BKE_packedfile_pack_all` → `BKE_image_pack` → `BKE_image_memorypack` → 普通路径，因此打包失败、自动保存不含像素、恢复回落黑图。本批给普通路径补同样的元数据摘除重试（image.cc:1486-1497，before 79b1bb1d… after fe2e3632…，+9/-0），两条路径日志文本仍相同。功能测试 NOT_RUN、acceptance NOT_CLAIMED。

+## 2026-11-01 作者态案例改走真实入口并修正证据漂移
+- metaball / sculpt / fcurve 三个案例由自建 WebEngineClient 改为驱动应用自身 `__nativeWorkflowEngine`，并以 `blend-file-input` 真实加载、`保存项目` 下载后重开；三例 Chromium 均通过，acceptance=NOT_CLAIMED，回执存于 `tests/golden/WBV2-P1424-001/artifacts/authoring-green-20261101-rerun/`。
+- 期间发现并修复两处自有缺陷造成的偏差：直接对应用 worker 发 `openBlend` 会与 App 启动时的自身打开竞争，导致快照在无 `snapshot` 调用时也被替换；`setFrame` 在桌面属非历史命令，fcurve 案例的可撤销编辑改用 `deleteObjectKeyframe`。
+- 证据哈希修复：三份已绑定 production receipt 曾被重跑覆盖成 DRIFT，现按归档副本恢复为绑定值（`288892aa…`/`5c2e3933…`/`e471df93…`），并把 P1137/P1142 manifest 内的引用同步到现文件。
+- B3 spec:133 缺口经 `b3-cleanfix3-20261101-run` 证据确认已闭合：quit.blend 缺失与损坏时 `NATIVE_INVOKE_FAILED` 均带原生报告文本。剩余为聚合验收与冻结候选，仍未 CLAIMED。
+
+## 2026-11-01 浏览器会话内 Python 编辑后撤销被守卫误拒
+
+案例：`fx_comp.blend`（`tests/files/sequence_editing/effects`）执行一次 Python 后按 `applyCommand {type:'undo'}`，桌面可正常撤销，Web 返回 `BLEND_READ_FAILED: PYTHON_RESET_MAIN_CHANGED`。
+
+源码定位：`web_engine_api.cpp:1128-1200` 的 `reset_python_before_main_replacement` 在重置前后各写一次 Main 并逐字节比对；`web_engine_main_state.cpp:3708` 的 `web_engine_blend_main_context_refresh` 在首次路径上通过 `WM_msgbus_create` 补建消息总线并绑定编辑器区域，属一次性运行期初始化。
+
+证据：同一会话内第一次 `pythonReset` 必改字节（`changed:true`），第二次 `changed:false`；不跑 Python 时连续重置字节完全稳定；`jsonCommand undo` 成功而 `applyCommand undo` 失败，差异在于后者经 `restore_history_entry` 走守卫。
+
+改动：`web_engine_api.cpp` 中守卫在首轮比较判定为变更后再做一次重置与写出，以相邻两次重置的差异作为最终判定。
+
+复测（NOT_CLAIMED）：exec -> `applyCommand undo` 成功，redo 回到编辑态；handler 析构在重置期间真实改写场景名时守卫仍拒绝替换，场景名保持 `CleanupHandlerScene`。

+- 目标 active / in_progress / NOT_CLAIMED，原始图片工作流仍失败，后端六案例通过不外推为整体验收；未部署、未推进队列。
+
+- 2026-11-02 模块级实测（Chromium，候选绑定）：冻结候选 `build_web_main_desktop/versioning-filepath-20261101`（candidate.json 6ba7b22c…、wasm d6c90802…）与当前工作树重打包候选 `build_web_main_desktop/modules-candidate-20261102`（candidate.json 0bbdce9a…、wasm 9df8b019…、App-Hkpp0JpV 6f3d552f…）分别按 7 个模块跑候选可跑 spec，结果写入 `tests/golden/WBV2-P1424-001/candidate-modules-20261101/manifest.json`。通过：材质/属性 2/2、sequencer 1/1、device-loss（`?ui=web`）。失败但定性为测试口径：worker-crash 期望对象名 `Cube`（fixture 为 `BasicCube`）、`smoke.spec.ts` 与 215 个 spec 依赖 `/src/*` 无法对静态候选执行。真实或待定缺口：recent-project `modalActive` false（dev 同样失败）、`blender-app` 导入路由仅 OBJ（2026-10-24 既定守卫）、对象编辑 `selected` 断言、viewport 入口敏感。关键发现：`main.tsx`（未提交，HEAD 为 `<App />`）把 `/` 渲染为 `localOnly=true` 桌面态，`?ui=web` 才是 Web 工具界面；71 个候选可跑 spec 中 26 个仍走 `/`。原生 `setDriverExpression` 经产品入口实测 `ok:true` 且 `frame*2` 在帧 1 得 `[2,0,0]`，动画缺口在 UI 侧命令未发出而非内核。门禁：部署 HTTP/缓存/契约/发布包/性能通过；`check-chromium-release-freeze` 绑定 2026-08-19 归档报告（single/js 25aa5136… vs 实物 79647f65…），`engine-manifest.json` 已按实物重生成；`check-rc-release-recovery` 断言字面量 `anchor.download = "blender-web.blend"`，源码已改为 `downloadName`（回退同名）。validation PARTIAL / acceptance NOT_CLAIMED；未执行部署。
+
+- 2026-11-02 入口口径复核：`web/app/src/main.tsx`（未提交；HEAD 为 `<App />`）把 `/` 渲染成 `<App localOnly={ui!=='web'}/>`，即根入口是桌面原生工作面、`?ui=web` 才是 Web 工具界面。以此口径重跑同一批 spec（未改断言）：action-marker、device-loss、worker-crash 转 PASS（worker-crash 同时把对象名 `Cube` 修正为 fixture 实际名 `BasicCube`，属测试缺陷修正）；viewport 3/8 通过；b5-animation 仍失败于 `waitNativeModal` 空；recent-project 三条超时于等待 `桌面` 按钮（该按钮只在根入口渲染，属入口依赖）。对象编辑 `selected` 断言经桌面验证为过期：桌面 `collection.hide_viewport=True` 后 `select_get()` 为 False，恢复可见后仍为 False。结论：入口口径可解释本轮大部分失败，剩余真实项为 b5 `waitNativeModal`、recent-project 的 `modalActive` 与入口耦合、以及 `App.tsx` 导入路由仅 OBJ（2026-10-24 既定守卫，但 WASM 内 `import_scene.gltf/stl/ply` 均可用，属可选扩展缺口）。acceptance 仍 NOT_CLAIMED。
+
+- 2026-11-02 模块补跑收口：在 `?ui=web`（Web 工具入口）下补跑导入导出、序列与上游 blendfile_io：`io-format-ui-gate` 仍因 accept 仅 `.blend,.obj`（2026-10-24 OBJ 守卫）失败，两个入口一致；`sequencer` 改走 `?ui=web` 后失败于等待 `native-web-tools-toggle`（该控件只在根入口渲染）；`upstream-blendfile-io` 超时于等待 `Python 输入` 标签。材质/属性模块在当前工作树候选 `modules-candidate-20261102`（wasm 9df8b019…）上 2/2 通过，与冻结候选一致。`?ui=web` 下未观察到 `gpuUI` 帧（`__nativeWorkflowGPU` 为空），因此 `waitNativeModal` 类断言在该入口不适用。阶段性结论：模块可跑项已全部实测，失败分为三类——入口口径（26 条根入口 spec、sequencer、recent-project）、既定守卫（导入仅 OBJ）、测试与夹具口径（worker-crash 对象名已修正、viewport 修订号断言、`/src/` 依赖 spec 不可对静态候选执行）。真实待决项：`/` 与 `?ui=web` 哪一个是产品入口（需产品决策）、`App.tsx` 导入路由是否放开 glTF/GLB/STL/PLY（WASM 内 import_scene 均已可用）。acceptance 仍 NOT_CLAIMED，未执行部署。
+
+- 2026-11-02 dev 服务器对照：对依赖 `/src/*` 的 spec 改在 Vite dev 服务器执行，作为静态候选不可用的补偿证据。`save-interruption`（M7-05 存储中断后 revision/hash/bytes 还原）通过；`storage-budget`、`io-format-ui-gate`（OBJ 守卫）、`recent-project`（`modalActive`）在 dev 上同样失败，说明这些不是候选漂移而是源码现状；`object-editor` 在 dev 上失败于保存步骤（候选上失败于工作台点击），差异来自入口口径而非候选质量。结论与残余登记在 `tests/golden/WBV2-P1424-001/candidate-modules-20261101/manifest.json` 的 `devServerCrossChecks`。
+
+- 2026-11-02 恢复与守卫复验：`upstream-blendfile-autosave.spec.ts` 三条在冻结候选上全部通过（2.2m），此前记录的 `NATIVE_GESTURE_ACTIVE` 失败绑定于旧 revision（当时 spec sha 7ddcb5d4…，现 e549f175…，文件为未提交状态且 2026-11-01 20:25 修改），不可与本次直接比较；`native-active-gesture-guard.spec.ts` 同候选通过，真实拖拽进行中危险操作仍被拒绝，Main 与 history 不变，说明守卫未被绕过。入口口径补充：`main.tsx` 只在 `ui==='desktop'` 时渲染 `DesktopWorkspace`，其余（含 `/` 与 `/?ui=native`）都是 `localOnly` 的桌面原生工作面，`?ui=web` 才是 Web 工具界面；实测两个原生入口 DOM 一致。
+
+- 2026-11-02 后端会话归属模块 PASS：`backend-session-ownership.spec.ts` 在冻结候选上 6/6 通过（2.0m），覆盖跨会话资产归属隔离、原生退出恢复未保存 Main、外部图像资源恢复、异常进程丢失只回退到最后自动保存、被驱逐的自动保存仅保留浏览器检查点回退、检查点写入失败保留 Main 并重试恢复。前置条件如实记录：`WEB_BLENDER_PROFILE_ROOT` 必须位于 `tests/golden/` 之下（spec 内断言），`BLENDER_BIN` 指向 `build_blender_native/bin/blender`；首次运行失败即因我把 profile root 放在 `web/` 下，属测试前置错误而非产品缺陷。同模块的 `recent-project-native-production` 仍为 1 通过 / 2 失败（`modalActive` 期望 true 实得 false），dev 服务器同样失败。
+
+- 2026-11-02 门禁与发布入口收口：通过的门禁为 deployment-http、deployment-cache、deployment-contract、deployment-runbook、release-package（57 文件 / 509816409 字节）、release-performance（默认预算：100k=62239ms，1M=407ms）、release-evidence（17 条记录 0 缺失）、malicious-archive-fixtures、rc-known-limitations、rc-release-notes、io-format-receipt-freshness（14 条回执，伪造/过期/跨版本均拒绝）。失败的四项均为验证产物过期或与契约漂移，不是产品行为缺陷：`check-rc-manifest`（清单提交 122142c2… 与 HEAD a081c68c… 不符）、`check-chromium-release-freeze`（绑定 2026-08-19 的 M14-01A 报告 single/js 25aa5136…，实物 79647f65…）、`check-rc-release-recovery`（断言字面量 `anchor.download = "blender-web.blend"`，工作树改为 `downloadName`，回退值同名、HEAD 仍是字面量）、`check-csp-resource-policy`（工作树契约给 img-src/media-src 加了 `blob:`，产品确有 `<img src=blob:>`、CSS `cursor:url(blob:)` 与序列媒体用途，检查器早于该契约变更）。发布入口在冻结候选上 7 条中 4 条通过（`upstream-blendfile-versioning` 四条原始资产打开全过），3 条 `cross-browser` 失败中 1 条是 `/` 桌面浮层拦截 `添加立方体`（切换 Web 工具后同一点击成功，已实证），2 条依赖 `/src/storage/StorageClient.ts` 只能由 dev 服务器提供。acceptance 仍 NOT_CLAIMED，未部署。
+
+- 2026-11-02 缺陷定性收尾：`/` 渲染桌面原生面（带 WebGPU 参数时原生画布 `data-native-input-ready=true`，属性区为空），Web 工具界面只在 `?ui=web`；`native-web-tools-toggle` 能在 `/` 放出 Outliner 并让工具栏可点，但属性 workbench 不会出现，属既有入口设计而非新缺陷。据此定性：真实缺陷三项——`recent-project` 变换后 `modalActive` 恒为 false（dev 与 `?ui=native` 同样失败）、`?offscreen=1` 下 `data-renderer-pixels` 始终缺失（24 秒 12 次采样全空，worker `frame` 消息本身带 `visiblePixels`）、导入选择器仅 OBJ（既定守卫，`import_scene.gltf/glb/stl/ply` 在 WASM 内可用，属可选扩展）。测试口径问题——`object-editor` 第 201 行期望集合隐藏后仍 `selected:true`（桌面实测隐藏会清除选择且不恢复）、`b5` 的 `read()` 在 `changed=false` 后仍等新帧（空闲画布不再出帧）、26 条 spec 仍以 `/` 为入口。已实施的测试修正仅 `worker-crash` 对象名 `Cube→BasicCube`。候选结论：BLOCKED / acceptance NOT_CLAIMED，未部署。
+
+- 2026-11-02 失败收窄：`native-active-gesture-guard` 以 `focusNativeViewport → 'g' → waitNativeModal(true)` 的相同路径在冻结候选通过，说明原生模态链路正常。因此 b5 的失败点在于 `exposeWebTools` 之后画布转入非活跃、绘制循环空闲、不再产生新的 `gpuUI` 帧，`waitNativeModal(false, afterId)` 自然超时（测试口径）；`recent-project` 的 `modalActive` 失败发生在其自身的项目替换/重启流程内（dev 与 `?ui=native` 同样复现，保留为真实待查项）；offscreen 的 `visiblePixels` 在 `render()` 内采样，只在场景/相机变化时重绘，属性值反映最后一次空闲帧而非渲染损坏。候选仍 BLOCKED，acceptance NOT_CLAIMED，未部署。
+
+- 2026-11-02 机制定案：`native-web-tools-toggle` 的 `onClick` 直接 `setGPUSurfaceOpen(false)`，原生浮层随即 `pointer-events:none`、`z-index:-1`，此后不再产生新的 `gpuUI` 帧。b5 正是在 `exposeWebTools` 之后等新帧，必然超时（测试口径）；`native-active-gesture-guard` 无此切换，故同一模态链在该候选上通过。`recent-project` 的失败等待位于 `transformNative` 内部、早于 `exposeWebTools`（spec 第 24 行），不受该机制影响，`modalActive` false 对 true 仍保留为真实待查项。另记：脱离 `observeNative` 夹具的独立探针无法复现 `focusNativeViewport` 的 VIEW_3D 区域聚焦路径，其按键投递结果不作为推翻夹具证据使用。
+
+- 2026-11-02 `modalActive` 根因确认：对照组 `modeling-native-modal-production.spec.ts` 在冻结候选与 Vite dev 服务器上以同样方式失败（期望 `active:true` 实得 `false`），说明 `gpuUI` 调用后 `modalActive` 从不置真，属既有原生与 UI 之间的模态状态缺口，不是候选漂移，也与 Web 工具切换无关。受影响范围：`recent-project-native-production` 两条、b5 的 `read()`（叠加切换关闭画布）、以及任何 `waitNativeModal(page, true)`；`native-active-gesture-guard` 通过是因为它断言守卫拒绝变更而非模态置真。未完项与证据见 `tests/golden/WBV2-P1424-001/candidate-modules-20261101/manifest.json`，候选 BLOCKED / acceptance NOT_CLAIMED，未部署。

+- PLY 已接通原生 PLY_import；b2e64510 / JS 39784d76 候选的原始 cube_ascii.ply 与强化 STL 回归均 PASS，含原始 io_report.fmtf 精度的 UV/颜色/法线、撤销重做、失败保留和保存重开。其余范围与 GPU 图像失败继续保留，仍未整体验收。
+
+## 2026-11-03 当前候选有界结果
+- 当前冻结候选：build_web_main_desktop/goal-native-mesh-export-20261103；WASM e75c6c6188acbb7d18cde4fb6df2b31b9973f315cd61da8c1156e2ddf7e4e87e，JS 39784d76a1ddbec359057586668fc7002fa0683478e5dfbfc3ab2092c879e060。
+- 补齐原生操作搜索弹窗布局、隐藏画布的交互调度，以及 STL/PLY 原生导出准备/完成通知/浏览器交付；非法文件名、取消、桌面重导入对照和 Main/history 保留通过。
+- 当前选定本地 WASM 8 项与后端 6 项通过；含真实拖拽守卫、重启自动保存、原生退出生产/持久化失败与回退、engine/storage Worker 终止恢复、实际源站存储删除与外部备份恢复。模式分开，数量不是整产品完成度。
+- 可复现计划、退出码、哈希及回执：tests/golden/WBV2-P1424-001/goal-current-scoped-assessment-20261103.json。自然驱逐触发、整浏览器/物理掉电不在上述保证内。
+- 图像 GPU 工作流仍未解决；导出覆盖/原生写失败变体、GLTF/GLB、其余已承诺模块及全局发布门禁继续保留。未部署，目标 active / acceptance NOT_CLAIMED；下一步见 continuation-20261103-goal-recovery-boundaries.json。
+
+- 2026-11-03 导出边界：同一 e75 候选的 STL/PLY 原生覆盖取消/确认、真实只读目标打开失败与恢复权限重试均 PASS；旧文件/Main/history 保留、实际下载/原生哈希/桌面对照一致。路径输入后的焦点处理遵循原始 file_directory_enter_handle 与 UI 文本编辑语义，没有更改超时或放宽断言。
+- 明确保留中途短写/ENOSPC 未验证项，不以 fopen 权限拒绝替代。新增 GLB 产品入口实际复现拒绝：插件源码已嵌入，但 NumPy 缺失且导入操作未注册；Linux NumPy 二进制不能冒充 WASM 依赖。后续见 continuation-20261103-goal-glb-import.json；整体仍 active / NOT_CLAIMED，未部署。
+
+- 2026-11-03 GLB 原生依赖：按 Blender 指定 NumPy 2.3.4 构建 13 个 CPython 3.13/Emscripten 静态扩展与原始 Python 包；修正主机头文件误选及旧版随机模块静态符号隔离，未改算法。构件身份见 build_web_numpy/build.json。
+- Chromium 已实际导入 NumPy；GLB 导入随后暴露工程重置后的插件路径缺口，已补原生 refresh_script_paths，正在重建。attempt-PXS6zh 使用 Vite 前端，仅为诊断；下一轮显式验证冻结 app。目标仍 active / NOT_CLAIMED，GPU 图像和其余模块/门禁保留，未部署。
+- 2026-11-03 普通 GLB 静态候选案例 PASS：goal-native-glb-node-fix-20261103（WASM ed97b858…），桌面对照、真实入口、原生 Main、撤销/重做、损坏文件数据/历史保留及保存重开通过；attempt-tMnS3N，退出码 0，无跳过/重试。见 goal-original-glb-assessment-20261103.json。
+- 修复 WITH_WEB UString 临时引用导致 ShaderNodeOutputMaterial 创建损坏字符串；原始 Meshopt/Draco 解码器仅在真实压缩分支加载。压缩依赖、资源/动画变体、GPU 图像和发布门禁仍保留，正按共享 IO 上下文改动复测 STL/PLY。整体 NOT_CLAIMED，未部署。
+- 2026-11-03 glTF 资源/骨骼案例收口：修正导入临时上下文受 Properties 编辑器钉选、插件重复启动注册及无权重分组读取分配空变形层；保留类型替换/手势保护。原始 2 动作、66 F 曲线、骨骼/权重、材质/贴图与桌面一致，撤销重做、失败保留和保存重开通过。
+- 当前 goal-native-gltf-readonly-20261103（WASM 382c70ea…）的 5 个选定 Chromium 静态候选案例通过，均退出 0、无跳过/重试；回执与哈希见 goal-gltf-current-scoped-assessment-20261103.json。整体仍 NOT_CLAIMED；下一真实缺口为原生 GLB 导出交付，压缩/多文件 glTF、动画/材质渲染、GPU 图像及全局门禁继续保留，未部署。

+The largest uncovered families are UI (`3930` rows), Media I/O (`585`), Nodes (`543`), Mesh Editing (`431`), Rig Animation (`375`), Object Operations (`316`), Simulation (`155`), Material/Render (`125`), Sculpt/Paint (`117`), Other Operators (`103`), Modifier System (`83`), and Core Scene Graph (`66`). These counts are planning scope, not parity claims. The functional batching, reuse rules and per-family exit gates are defined in [WBV2-NEXT-MIGRATION-WAVES.md](/home/mes123456/workinf_Blender_Wasm/docs/status/WBV2-NEXT-MIGRATION-WAVES.md:18).
+
+## Resolved blocker and open follow-ups
+
+The Audio/Speaker/ParticleSettings blocker was resolved without desktop Audaspace: the
+WebEngine now retains media metadata in a Scene IDProperty owned by authoritative Main,
+merges it on open/restore/refresh, and the Chromium production receipt passes after a
+fresh WASM build. Audaspace remains `WITH_AUDASPACE=OFF` because the Web target lacks
+the required Emscripten symbols. The GLB temporary dependency and Geometry Nodes
+allowlist/retention issues, Grease Pencil viewport selection, and Chromium MOVIE decode
+are fixed. MOVIE now falls back to a local ffmpeg.wasm Worker with same-origin core
+resources. Open follow-ups are historical IO/library hash drift and remaining
+uncovered Blender families.
+The module epoch is terminal by design, but the immutable
+parity inventory is not: 6,609 effective cases remain pending.
+
+## Execution policy
+
+Keep `docs/EXECUTION_QUEUE.md` at the terminal module checkpoint until a new source-
+backed family is explicitly selected. The GLB temporary bundle dependency, Geometry
+Nodes allowlist/retention behavior, Grease Pencil selection/marquee integration, and
+MOVIE decode fallback are already closed by source-backed receipts. Next work is the
+historical IO/library hash-drift corrective lane, followed by one explicitly selected
+uncovered family (UI, Media I/O, Nodes, Mesh Editing, Other Operators, or Core Scene
+Graph) with the same Main/Worker/frontend, negative, recovery and Chromium gates. The
+ffmpeg.wasm MOVIE fallback is implemented; extend it only with a new source-backed
+contract. Reuse existing implementation receipts by SHA-256; do not rerun generic
+continuation tasks, edit the 6900 inventory, or infer full-family parity from
+representative cases.

+- status: `in_progress`
+- Embedded Python traceback increment, 2026-09-17: retain bounded per-session submission source in the standard CPython linecache during execution/traceback formatting, with distinct virtual code filenames and finally restoration. Older retained function definitions can map to their own source; source cache limited to 32 entries/4 MiB of UTF-8 source, not total memory. Cycle 45 continues native GPU/WM source work; no competing build or publication. Root change source-only/unverified; no validation or full-completion claim. Report: `tests/golden/WBV2-P1424-001/python-source-traceback-implementation.md`.
+- Console namespace/continuation increment, 2026-09-17: matched native console defaults using actual bpy/C/D/mathutils/math and original help behavior; scoped displayhook last-result storage per session and cleared pending console input before Text execution. Cycle 39 generated a combined JS/WASM candidate (unverified, unpublished); continuation now supersedes old linker lists with newer build results and prioritizes unfinished business entry points. Cycle 40 source work continues, with a newer compile failure under repair. Root console changes source-only/unverified; no tests or full-completion claim. Report: `tests/golden/WBV2-P1424-001/console-namespace-implementation.md`.
+- Native Preferences/Spreadsheet integration, 2026-09-17: linked and registered original Preferences storage/runtime/search plus preference operators; compiled its native archive and an explicit unsupported browser file-association branch. Subsequent link retained only Spreadsheet ID/table readers; original Spreadsheet module, space and operator registration are now wired for the next required build. Graph/Properties worker edits preserved; service continued to GPU cycle 39. No runtime verification, full UI claim or published WASM replacement. Report: `tests/golden/WBV2-P1424-001/preferences-spreadsheet-implementation.md`.
+- Native bpy app/DDS increment, 2026-09-17: WebEngine now reuses creator buildinfoobj and the configured OIIO version-query target; bpy.app.oiio reports unsupported for the existing Web version-0 implementation. Those sources compiled in cycle 35 build-01, with final link still blocked. Original compressed DDS upload loader moved into a shared OIIO-independent unit for the native GPU image path; its new compilation remains pending. Python service continued into cycle 36 GPU work. No full image-codec support, runtime acceptance or completed full objective claimed; published WASM preserved. Report: `tests/golden/WBV2-P1424-001/bpy-app-dds-implementation.md`.
+- Native bake-storage increment, 2026-09-17: reused original Blender bake read/write/copy/free and query code in shared MOD_nodes_storage; Web modifier storage callbacks now preserve nested bake resources/panels and traverse referenced IDs. Geometry evaluation and OCCT/display routes unchanged. Python execution continued from cycle 33's partial WebGL backend into cycle 34 node-editor work; build-02 compiled the shared storage unit, then final link failed on separate node fallback duplicates. Behavior remains unverified; published WASM preserved; no tests or acceptance. Report: `tests/golden/WBV2-P1424-001/nodes-bake-storage-implementation.md`.
+- Overload and Python bridge recovery, 2026-09-17: cycle 33 recovered from an explicit overloaded-server reconnect and began native WebGL GPU backend source work. Added visible reconnect/recovery state and overload-specific shared backoff, loading after its handoff. Repaired rejected Python bridge chains, stale completion, and reset paths that skipped native cleanup or hid errors. Root changes source-only/unverified; no validation or competing build. Full objective remains incomplete. Report: `tests/golden/WBV2-P1424-001/overload-bridge-implementation.md`.
+- Native GPU keyboard source increment, 2026-09-17: connected Unicode key scalars, punctuation/keypad/location/repeat handling through canvas, protocol, Worker and native GHOST events; retained physical modifier sides and added pre-dispatch/native bounds. `nativeUI` remains false: actual browser Blender GPUBackend, WM window/event and editor draw integration are still incomplete and are now explicit GPU continuation priorities. Python service continued through cycles 30-31 with source work and no current provider failure streak. Root input changes source-only/unverified; no competing build, validation or published artifact replacement. Report: `tests/golden/WBV2-P1424-001/gpu-keyboard-implementation.md`.
+- Executor stall recovery, 2026-09-17: identified cycles 22-24 as fixed startup-deadline interruptions with no tool actions; upstream cause is not established. Added bounded adaptive startup timing, shared provider backoff across focuses, categorized terminal errors, compact handoffs and explicit waiting/source-work telemetry. Activated automatically after cycle 25 handoff; cycle 26 bpy began source actions after 10 seconds with a 600-second startup deadline and the latest shared build log. Cycle 25 Screen/WM source work was preserved. Python console host/Worker dispatch failures now clear pending state and timers. All changes `IN_PROGRESS_UNVERIFIED`; validation `NOT_RUN`, acceptance `NOT_CLAIMED`, queue and published WASM preserved. Report: `tests/golden/WBV2-P1424-001/provider-stall-implementation.md`.
+- Continuous business implementation, 2026-09-17: preserved cycles 1-19 and resumed unlimited Python execution as enabled user service `wbv2-implementation.service` (initial PID 1315777). Added shared build/blocker handoffs, content-based source progress, dependency-group steering and reload at worker boundaries. Fixed bpy reentrancy during initialization/reset/finalizers and scope-bound tracing/message cleanup. Changed native source compiled into the core archive; final WASM link remains blocked by native UI/layout/menu dependencies, and published artifacts were preserved. `NOT_RUN` validation, `NOT_CLAIMED` acceptance, no new source-unit bindings. Report: `tests/golden/WBV2-P1424-001/continuous-business-implementation.md`.
+- Recovery and bpy dependency implementation, 2026-09-17: Python loop now keeps per-focus handoffs, resumes partial edits, backs off failed/empty work and handles idle executors; user service `wbv2-implementation.service` started with unlimited iterations (initial supervisor PID 1151455). Enabled the existing WASM CPython dependency in Web CMake, compiled Blender Python archives, corrected context types and embedded native module/RNA initialization. Final candidate link remains blocked by 722 undefined-symbol diagnostics; published WASM preserved. Validation `NOT_RUN`, acceptance `NOT_CLAIMED`, source-unit binding delta 0. Report: `tests/golden/WBV2-P1424-001/unattended-recovery-implementation.md`; live state: `tests/golden/WBV2-P1424-001/unattended-implementation/state.json`.
+- Continuous implementation, 2026-09-17: added scheduler `--implementation-only` dispatch to a serial Python continuation loop for real bpy/RNA, native WASM GPU UI and editor operations. Legacy validation/publication is blocked in the active implementation phase. Started supervisor PID 1128210 with initial executor PID 1128211; runtime state: `tests/golden/WBV2-P1424-001/unattended-implementation/state.json`. Dispatch/activity only, no completion or acceptance claimed. Report: `tests/golden/WBV2-P1424-001/unattended-implementation.md`.
+- Embedded CPython implementation, 2026-09-17: cross-built supplied CPython 3.13.13 and linked it with original Blender Vector/Matrix/Quaternion/Euler/Color types into the same WebEngine WASM memory. Added persistent synchronous console/Text execution, native operator/RNA-read bridge, runtime selector, bounded output/deadline and shared interrupt/reset lifecycle. Artifacts `BUILT_UNVERIFIED`; no script execution, tests or acceptance. Full bpy/RNA registration, native GPU UI and complete editor operators remain incomplete. Report: `tests/golden/WBV2-P1424-001/embedded-python-implementation.md`.
+- Native region view implementation, 2026-09-17: authoritative RegionView3D fields now feed per-area browser cameras through compiled BKE projection; explicit view save/restore writes Main with undo/save support, resize projection and async cancellation guards added. WASM/frontend artifacts generated; `IMPLEMENTED_UNVERIFIED`, no tests or acceptance. Automatic navigation persistence, camera/quad/locked/local views, full bpy, native GPU UI and complete editor operators remain open. Report: `tests/golden/WBV2-P1424-001/region-view-implementation.md`.
+- Source workspace implementation, 2026-09-17: pure WASM display now uses actual WorkSpace tabs and native area rectangles/subtypes, with independent 3D views and compatible existing editor components. Text/image selection writes native editor data; scripts activate their originating area and expose actual Main editor context. Multi-area draft guards and viewport targeting added. WASM/frontend artifacts built, `IMPLEMENTED_UNVERIFIED`; no tests or browser acceptance. Complete bpy, GPU UI drawing, saved RegionView3D state and all editor operators remain open. Report: `tests/golden/WBV2-P1424-001/source-workspace-implementation.md`.
+- Browser Python implementation, 2026-09-17: reused local Pyodide 314.0.4 / Python 3.14.0 assets, added persistent console, Text run/import, bounded output/bridge calls, stop/reset and project-switch draining. `web_blender` dispatches actual Main commands/operators and RNA reads; no substitute `bpy`. Frontend artifact built, `IMPLEMENTED_UNVERIFIED`; no script execution, tests or browser acceptance. Desktop Python version compatibility, full bpy, GPU UI and complete native editor contexts remain open. Report: `tests/golden/WBV2-P1424-001/browser-python-implementation.md`.
+- WASM editor storage/context implementation, 2026-09-17: registered WM/Workspace/Screen IDs and source-derived storage callbacks for 18 editor types; replaced asset-shelf read stub, restored saved layout relations, added Main workspace/area/region commands and browser controls/history synchronization. Latest WASM/frontend artifacts built; `IMPLEMENTED_UNVERIFIED`, no tests or acceptance. Full GPU UI, Python/bpy, arbitrary native layout rendering and complete operator contexts remain open. Report: `tests/golden/WBV2-P1424-001/wasm-editor-context-implementation.md`.
+- browser UI/NDOF implementation, 2026-09-17: added explicit `?ui=wasm` entry with native execution disabled; actual material tree display and granular BKE node edits, Text creation/editing, real UV/image views, and WebHID -> shared C++ HID decode -> WASM navigation. Shared desktop trackball math is reused; idle/focus/disconnect handling added. Necessary WASM/frontend artifacts built; `IMPLEMENTED_UNVERIFIED`, no tests/typecheck/browser/device acceptance. Full WASM desktop UI, GPU/Python/editor context integration and complete NDOF behavior remain open. Report: `tests/golden/WBV2-P1424-001/wasm-ui-ndof-implementation.md`.
+- window/input/extension implementation, 2026-09-17: private Openbox host and local dependency preparation; native GHOST pressure/tilt/eraser ingress with RNA binding; logical keyboard/lock state and horizontal wheel transport; session-scoped HTTPS extension proxy preserving network isolation; WebEngine fallback when native session is unavailable. Candidate native binary and web bundle built, all new behavior `IMPLEMENTED_UNVERIFIED`; no tests/typecheck/browser acceptance. Whole native rebuild was stopped and replaced by focused WM/RNA generation and linking with existing libraries. Complete UI remains native-session dependent; full desktop parity not established. Report: `tests/golden/WBV2-P1424-001/window-input-extension-implementation.md`.
+- full desktop workspace implementation, 2026-09-17: default entry now connects an original-layout native Blender Main; menus/editors/context are rendered and executed by native Blender. Added browser file/folder transfer, project packages, native cursor/IME/clipboard, browser help links, browser and host recovery, native preference/startup persistence, offline user directories and bidirectional project-copy handoff with `?ui=web`. Frontend artifact built with typecheck skipped; `IMPLEMENTED_UNVERIFIED`, no tests or browser acceptance. This is a local native-session route, not complete WASM UI migration. OS window management, device/keyboard parity, online extension access, runtime display resize and remaining Web adapter limits stay open. Report: `tests/golden/WBV2-P1424-001/full-desktop-workspace-implementation.md`.
+- desktop workflow gaps, 2026-09-17: implemented labeled WASM undo history and direct snapshot jump; native exporter downloads for GLB/glTF/FBX/OBJ/STL/PLY/USD/Alembic with RNA options and resource ZIP; independent persisted native userpref.blend plus persistent Web interface toggles; 16 actual native editor area routes and same-session switching. `IMPLEMENTED_UNVERIFIED`; only necessary incremental artifact builds, no tests/typecheck/browser acceptance. Prior PASS records apply to earlier artifacts only. Web/native preference mapping, inline editor parity, plugin resources, other formats and history options remain open. Report: `tests/golden/WBV2-P1424-001/desktop-workflow-gaps-implementation.md`.
+- desktop-menu/header alignment, 2026-09-17: actionable File/Edit/Render/Window/Help and mode-dependent View/Select/Add/Object/Edit Mesh menus replace static text/long default toolbar. File export and actual native render/new-project paths corrected; shader types registered before Main read to prevent material loss during edit/undo/reopen. Final 23/23 menu workflows and 19/19 focused regressions PASS. Full desktop interface/function parity remains NOT_ESTABLISHED. Report: `tests/golden/WBV2-P1424-001/desktop-menu-interface-alignment.md`.
+- viewport navigation alignment, 2026-09-16: common Blender-default MMB orbit, Shift+MMB pan, Ctrl+MMB/wheel zoom, axis views, orthographic toggle and framing now share one controller across main/Offscreen. Blender Z-up camera conversion corrected. Both 21-step desktop/mobile flows pass with unchanged 18-node robot data; 120/120 relevant regressions and additional orthographic GPU depth check PASS. Guide: `user-manual/WEB_Blender_Viewport_20260916/WEB_Blender_Viewport_Navigation.pdf`. Scope excludes full navigation preferences/NDOF/fly/camera-view parity.
+- robot tool integration, 2026-09-16: Robot/F3 UI integrates built-in/custom URDF+STL import, assembly, joint pose/limit controls, six-axis checks, project recovery, subtree GLB export and mapping downloads. 21/21 user workflows and 118/118 focused regressions PASS; illustrated 19-page manual delivered.

Fixed GLB basis, viewport world-transform propagation and Outliner hierarchy. Focused 118/118 checks PASS; full 442 batch not rerun. Report: `tests/golden/WBV2-P1424-001/abb-irb120-web-workflow.md`.
+- desktop parity round 3 and user handbook, 2026-09-16: final fresh 244-file batch 442/442 PASS, zero failures/skips/flaky tests, unchanged inputs; native comparisons 32/32 and UI journeys 21/21. Ordinary console exceptions now retain locals and completed changes; all rotation modes use Blender native matrix construction with delta transforms and ordinary-object parent inverse. Independent 36-module usage PDF and UT-001–276 test manual delivered. Full desktop parity remains NOT_ESTABLISHED. Report: `tests/golden/WBV2-P1424-001/console-rotation-user-handbook.md`.
+- desktop parity user test round 2, 2026-09-16: final complete batch PASS, 244/244 files and 442/442 checks, zero failures/skips/flaky results, input hashes unchanged; native comparisons 22/22 and user journeys 20/20.

+# 2026-10-10 latest bounded status
+- Current scheduler cycle: `4312`; state: `waiting_retry` / `waiting_strategy_rotation`; `pendingSourceCycles=[]`.
+- Latest application candidate: `build_web_main_desktop/api-app-relinked-20261010/candidate.json`, bound by `tests/golden/WBV2-P1424-001/api-app-relinked-20261010-manifest.json`; native API/App aggregate was incrementally relinked and packaged from the same pair.
+- Implemented unverified routes retained: camera preset persistence/recovery, modal receipt propagation, shader relative/absolute dependency handling, Timeline selection/NLA editing and GP selection/draw cancellation. Validation remains `NOT_RUN`; acceptance remains `NOT_CLAIMED`; deployment was not performed.
+- Remaining concrete gaps: asynchronous WM terminal/focus edges, GPU/depth recovery, GP pressure/tilt and native placement, NLA Time Warp/Transition/Meta evaluation, browser runtime behavior, undo/redo and save/reopen. Broader task-card residuals remain unchanged.
+- continuationNotes batch=status-20261010: state and candidate fields copied from current authoritative `state.json`; no queue/pending/nextTask mutation; next action is strategy-rotated source implementation followed by a matching candidate, not validation.
+- 2026-10-10 调度阻塞修复：`print-task-context.mjs` 原先因任务卡历史责任段导致 estimatedContextTokens=3503、退出1；压缩历史说明后重新为 exit0，调度器随即进入 cycle-004322 worker。保留 task/parent/nextTask、pending/候选哈希和未验证边界，未运行功能验证。
+- continuationNotes batch=scheduler-unblock：根因是上下文预算超限而非源码缺失；后续顺序为 queue/context -> 当前 handoff -> 单一业务缺口 -> matching native build -> candidate handoff。避免重复启动服务、并行 native build和盲目重发大上下文。
+- 2026-10-10 调度器二次修复：连续 `worker_context_budget` 不再等待 branch 的长 `retryAt` 与三轮 strategy wait；父循环立即选择最小无进展分支做一次有界策略轮转，pending/旧候选/失败证据保持不变。
+- 2026-10-10 调度断点修复：camera-preset handoff 第34行仍是 cycle4188 历史记录，4324 因此重复读取已完成入口；已将该断点行替换为当前权威 manifest/释放说明，历史保留在周边 continuationNotes。`print-task-context.mjs` 仍 exit0。
+- 2026-10-10 调度顺序恢复证据：cycle-004325 已领取 `gpu/editor` 独立路径，跳过已交接 camera preset；上下文入口 exit0。新增 `worker_context_budget` 立即轮转逻辑已通过 Python 语法检查，保留 pending/旧候选/失败记录。

+
+以一个共享 Blender Main reader、WASM build、Worker 路由和 Chromium receipt 批量验证 GeometryNodeAccumulateField, GeometryNodeAttributeDomainSize, GeometryNodeAttributeStatistic, GeometryNodeBake, GeometryNodeBlurAttribute 的真实 modifier/RNA 元数据。

+- Selected RNA units: none (source-only dependency batch)
+
+## 验收
+
+- one shared Main/WASM/Worker/Chromium chain observes every selected type
+- malformed input is rejected without Main mutation
+- save/reopen and deterministic second read are exact
+- only Chromium is used; JS simulation and per-API duplicate workers are forbidden
+- each selected source unit receives an explicit hash-bound coverage binding
+- `node tools/web/check-task-context.mjs --task WBV2-P1185-001 --write`
+
+## 失败边界
+
+- any missing source, unsupported type, hash drift, malformed data or non-exact recovery keeps the batch `in_progress`/`blocked`
+- partial batch success never claims the omitted family; historical inventory remains read-only

+# WBV2-P1424-001 重启接续（2026-09-23）
+
+## 暂停状态
+
+用户明确要求暂停。cycle 863 在写出完整 handoff 后安全停止；systemd 服务 inactive/dead，PID 0，NRestarts 0。`hold-after-handoff.request` 保留，`stop.request` 不存在。源码、build tree、候选、日志均保留；未执行验证、部署、队列推进或清理。
+
+恢复时只移除 hold 并启动原服务：
+
+```bash
+cd /home/mes123456/workinf_Blender_Wasm
+python3 - <<'PYRESUME'
+from pathlib import Path
+Path('tests/golden/WBV2-P1424-001/unattended-implementation/hold-after-handoff.request').unlink(missing_ok=True)
+PYRESUME
+systemctl --user start wbv2-implementation.service
+```
+
+服务已 active 时不要重复启动。不要启动第二个 Python loop 或第二个 scheduler。
+
+## 当前产物与待组合源码
+
+- 最新明确候选：`build_web_main_desktop/decimate-normal-through-847-20260923/candidate.json`。
+- candidate cycle：847；状态 `implemented_unverified`，未部署。
+- 暂停时 pendingSourceCycles：848、849、853、857、858、859、862、863。
+- cycle 863 已实现 evaluated `ModifierData.error`、Subsurf GPU 禁用说明和 CPU/GPU 混合状态反馈，尚未进入候选。
+- cycle 859/862 的原生按钮、弹窗、gizmo owner cleanup/取消收尾源码尚未进入候选。
+- 根会话已修复 `wm_event_system.cc` 的编译错误：错误的 `LISTBASE_FOREACH(ARegion *, ...)` 已改为 `for (ARegion &region : area->regionbase)`，并保留 `&region` owner。
+
+## 已完成且不要重做
+
+- Subsurf：12 个参数及原生 enabled/visible 条件。
+- Decimate：三种模式、对称轴、顶点组、Delimit enum-set 多选/清空、只读 Face Count。
+- Weighted Normal：权重模式、顶点组及反转启用条件。
+- Select All/None/Invert 已走 `VIEW3D_SELECT` 原生路由；G/R/S 已走 `gpuUIInvoke` 原生 modal 路由。
+- DesktopDialog 已补可见/可用焦点遍历、输入优先焦点、焦点恢复和 IME Esc 隔离。
+- 候选目录形式的 artifact handoff 已被 `candidate_handoff_paths` 识别，避免重复打包；打包后新增源码仍保留 pending。
+- Alembic 已在主 WebEngine 配置启用；OpenUSD/TBB core、静态 pxr wrapper、Python package 已生成，不能重复下载或重建 TBB/core。
+
+## 优先断点一：OpenUSD Imaging 安装集
+
+`bf_io_usd/usd_reader_shape.cc` 需要 `pxr/usdImaging/usdImaging/{capsule,cone,cube,...}Adapter.h`。这些头在 `build_web_usd/OpenUSD-26.03/pxr/usdImaging/usdImaging/`，但未安装到 `build_web_usd/install/include/pxr/usdImaging/usdImaging/`。
+
+`PXR_BUILD_IMAGING=ON`、`PXR_BUILD_USD_IMAGING=ON` 已在 cache 中；`tools/web/build-webengine-usd.py` 已改为启用 imaging，并传入现有 OpenSubdiv 源码/静态库。
+
+最新失败原因是 cache 中过期的 `OpenSubdiv_DIR` 指向 `build_web_blender6/extern/opensubdiv-web/OpenSubdivConfig.cmake`，该导出配置计算出不存在的 include 路径。下一步只删除这个 cache entry，不清理 build tree：
+
+```bash
+cmake -UOpenSubdiv_DIR -S build_web_usd/OpenUSD-26.03 -B build_web_usd/usd-build
+```
+
+实现时保留 `OPENSUBDIV_INCLUDE_DIR=blender-5.2.0/extern/opensubdiv-source`、`OPENSUBDIV_OSDCPU_LIBRARY=build_web_blender6/lib/libosdCPU.a`、`OPENSUBDIV_OSDGPU_LIBRARY=build_web_blender6/lib/libosdGPU.a`，然后复用现有 USD install 目标：
+
+```bash
+python3 tools/web/build-webengine-usd.py --stage usd --usd-target install
+```
+
+最近失败日志：`openusd-imaging-r2-20260923.log`、`openusd-imaging-r3-20260923.log`、`openusd-imaging-r4-20260923.log`。不得复制伪 adapter 头、删除 shape reader 或声称 core archive 等于可用 USD 后端。
+
+## 优先断点二：主 WebEngine 续编
+
+OpenUSD install 完成后，复用现有主 build tree：
+
+```bash
+ninja -C build_web_blender6 -j8 web_engine
+```
+
+cycle 862 首轮在 `wm_event_system.cc:3296` 编译失败，该源码已修复；首轮已生成约 2053/2808 对象。后续续编应复用这些对象。成功后只打包一次匹配候选，artifactPaths 必须含明确 `candidate.json`；不运行浏览器或测试。
+
+## 功能余项
+
+- `G01-F3-LOCAL-EXEC`：USD Refresh Archive → `bf_io_usd/USD_create_handle`；USD import/export hook → 静态 `pxr.Usd`/`pxr.UsdShade` 注册进入主应用。
+- `G01-PROP-STACK`：Subsurf evaluated runtime 状态已接入；其它原生 modifier/constraint 参数族和完整错误面板反馈保留。
+- `G01-SELECT-RESTORE`：gizmo modal/拖拽/取消源码等待匹配候选；未验证不是重新实现理由。
+- `G01-GP-PLACEMENT`：Stroke/Surface foreground depth 的具体消费/取消分支继续保留。
+- 菜单、工具栏、对话框、面板、右键菜单、状态栏、区域等 UI 模块均未宣称整模块完成。
+
+## 接续规则
+
+- 主线只做桌面 Blender UI → Web Blender UI 的具体功能补漏。
+- 同类问题集中处理，复用现有源码、WASM、协议、Worker、原生 owner 和候选。
+- 只有必要的增量构建；原生固定 `-j8`，不 clean、不重复编译未变目标。
+- 全部功能实现完成前不运行测试、浏览器、类型检查、独立语法检查、上下文检查或证据审计。
+- 构建成功、候选生成、轮次、心跳都不等于功能完成或验收通过。
+- 保留工作区所有现有改动；不得 reset/checkout/clean。

+原生 Draw Pass → GPU_compute_dispatch → WebGPU → 原生缓冲区 → GPU_memory_barrier → 后续读取/绘制
+
+原生 buffer compute 后接 buffer barrier 的生产实现；附支持位表、资源版本流转和错误传播，不改全局功能完成标记。

+- 当前 dispatch 在 Worker 全量 readback 后返回，尚不能据此宣称所有 barrier 类型均已支持。
+
+## 实现步骤
+
+1. 保留直接 dispatch 及零 workgroup 原生语义，沿 DrawCommand 的 barrier 调用完成真实业务接线。
+2. 为 SHADER_STORAGE、BUFFER_UPDATE、VERTEX_ATTRIB_ARRAY、ELEMENT_ARRAY、COMMAND、UNIFORM 等实际枚举建立生产者/消费者映射；执行时读取 GPU_state 相关头文件确认名称与语义。
+3. 对已实现的同步 buffer 路径，明确何时完成 WebGPU 提交、映射、原生 commit 及 WebGL upload；仅在这些条件成立时完成对应 barrier。
+4. 混合 bitmask 逐位处理；texture/image/framebuffer 屏障留给 CS08，未知标志保持明确失败，不能一次清空所有 guard。
+
+## 失败边界
+
+屏障只有在对应生产者写入已提交、消费者缓存已同步时才可结束；不能用空函数冒充实现。
+
+发生阻塞时记录具体业务、原生函数/create-info、producer/consumer 和下一修复动作；保留既有产物，继续无此依赖的实现卡，不用缺失证据作为实现阻塞。
+
+## 延后的用户场景（当前不执行）

+2. 形成稳定 binding 表：资源类别+native slot → group/binding；保留 UBO/SSBO 同号槽位及原生查询位置。
+3. 完成 std140/std430 对齐、矩阵步长、结构/数组步长、紧凑数据访问、push constant 数组以及 specialization 的类型化映射；每次扩展由真实 caller 驱动。
+4. 将原生路径、create-info 名、阶段和编译诊断带回调用者；映射实际设备 storage 数量、workgroup 大小/共享内存及原子操作要求。
+5. 遇到 Naga 前端缺口先定位原生 shader 与编译器现有能力，做等价 lowering；不得改 shader 数学语义或静默跳过资源。image 声明的完成依赖 CS08。

+4. 逐业务记录实现/未实现边界、source binding 增量、具体阻塞和下一修复动作；全部专项功能未完成就保持 in_progress。
+5. 只完成本专项不触发全项目用户验证；全项目所有功能实现完成后才交 CS14。

+## 首要约束：接续十多天已有移植成果
+
+- 本计划的 DW 编号是“功能补齐责任包”，不是 31 个从零重做的项目。已有 16 模块、34 任务、原生主入口、Python、GPU 与本地候选全部作为基础保留。
+- 领取时只读执行队列、当前上下文、本阶段小入口及当前一张 DW 卡；复用证据按需取一个结果的 summary/remaining/changedFiles，随后只检索列出的精确生产入口。不要默认加载总规划、所有 status、完整 route catalog 或 inventory。
+- 第一个实现动作是定位同一功能现有 producer→protocol→Worker→consumer→history/storage，辨别“已有实现”“只差接线”“缺必要依赖”“真实缺失”。已有完整实现仅引用并保留，不重复编码/复制协议/创建新 Worker。
+- 旧任务卡 planned、早期 remaining、历史 LINK_BLOCKED 和总表 in_progress 都不能单独证明代码尚未实现。结合后续 scoped handoff 和当前聚焦源码判断，不运行验证来决定是否重做。
+- 优先复用已有源码、OCCT WASM、WebEngine/Python/Naga、模块及候选。只在所需范围读取其版本/接口/已记录哈希；产物需适配或缺失时增量生成，生成时记录 SHA-256。不得把哈希元数据当功能通过证据，不开展独立证据审计。
+- 未在该包聚焦阅读过的原生 operator/node/modifier，不宣称已明确缺失；领取后按模块小批量定位，保留实现存在但未验证这一状态。
+
+## 共同实现契约
+
+一个连贯包包括真实用户入口、原生 Blender 5.2 operator/reader/context、协议/Worker、生产者/消费者、Main/资源所有权、错误/取消、undo/redo 与 save/reopen 的适用语义。UI、GPU、bpy 围绕同一工作流补依赖；这些角色不是可各自宣称全局完成的独立项目。
+
+功能实现必须使用原生 WebEngine/WASM 路径；JS 只作浏览器能力接线。几何运算统一到已有 OCCT 出口，需要的算法语义在此扩展绑定/适配；不能另建平行几何实现。Three.js 只显示。现有服务端/本机能力保留可用性，但不记成 browser-native 移植完成。浏览器等价能力须保留操作者目的、数据与错误语义；纯 OS 机制差异必须有实际可用替代，不用禁用按钮算完成。

+每包先沿用旧源代码，再补具体断点。跨包依赖可先实现最小共享接口并回到业务；dependsOn 表示完整交付所需接口，不禁止提前完成独立子项。发现新依赖写入包内剩余，不默认全量重排队列。多个包涉及同一文件时以一个生产所有者串行写入，必要 build/package 串行复用，不能并发覆盖同一产物。
+
+全部功能实现前不运行测试、回归、冒烟、浏览器验收、类型检查、独立语法检查、上下文检查、性能基准或证据审计。源码阅读是定位实现，不能出具验证通过结论。只为生成所需构件做必要增量编译；编译成功不等于功能完成。
+
+## 每轮交接（不作为验证命令）
+
+报告必须列：业务入口；原生 operator/create-info 与 source path；复用的既有结果/构件；保留实现；本轮补齐的具体缺口；仍未实现的精确路由/原因/下一动作；产物及版本元数据（若生成）；implementationStatus；validation=NOT_RUN；acceptance=NOT_CLAIMED。不以报告数、循环数、文件数或路由分类数统计完成功能。
+
+状态分开记录：reuse_assessment_pending → implementing_gap / blocked_concrete → implemented_unverified → ready_for_user_use → user_confirmed。计划中的 planned_gap_closure 只表示尚未记录本计划交接，不否认其已有代码。记录包含 codeOrigin 和 previousResult，允许已完整实现的子项直接保留为 implemented_unverified；不虚构本轮开发或通过结果。
+
+缺口条目最低字段：workflow、operator/node/modifier/reader、sourceUnit/sourcePath、entry、producer、consumer、executionRoute、missingBehavior、ownerPackage、nextRepair、implementationStatus。设备或编译器暂不支持仍是明确缺口，不能删除或把“不支持”标成已实现。
+
+每 30 分钟或 3 次实现交接做一次本包聚焦源码梳理；重复同一业务阻塞提前处理。此举不是运行验证。先修源码/绑定/依赖；未解决则保留构件，继续无此依赖的子项，不循环生成无实现变化的报告。实际功能仍未完成，不得通过改状态跳过。
+
+## 产物和交接状态
+
+完成一包说明实现的业务语义闭合，但运行结果仍未验证。每包涉及的逻辑接口与必要构件持续对齐，最终 DW31 汇总完整候选；不能把所有集成拖到最后才发现只有孤立源码。旧已发布产物和候选保留，本阶段不发布部署。
+
+现有 desktop-delivery-manifest 的七阶段 ID 和 focusOrder 保留。新增的包索引是交接计划，现有调度器仍按 stage/focus 工作；不声称它已具备自动 DW DAG 调度。下一安全轮次从阶段 focus 中读取小入口，再沿最新交接选择一个包。不能把完成一张 DW 卡当作整阶段 focus 完成。
+
+队列只认根 manifest 的 nextTask；DW/CS 不创建新的队列任务，不手动推进主队列。计划不会启动、停止或重置已有执行进程。遇到旧阶段进度滞后，按现有真实实现补交接，不能重做业务。
+
+## 后续用户使用
+
+所有目标功能实现完成后进入 USER01，操作者在 Chromium 使用时测试。此时收集具体操作/素材/版本/预期/实际，按原包修复并继续使用；不能提前要求用户代测每个未实现包。仅本包完成不解锁任何中途验证。
+
+源码覆盖记录沿用当前目录历史快照：unitCount=3802、verifiedUnits=1025、unverifiedUnits=2777、sourceTreeSha256=311791df5e2b96c31ee9cefd5ab0c9a8ded87309f1a814c3b92dec328a607d6a。未刷新、不代表当前树哈希；本次计划新增绑定/验证均 0。后续只记实际绑定增量，不伪造 verified 增长。
+
+## 跨包共享接口的交付次序
+
+新计划按 DW 业务依赖领取；旧 CS 卡的 dependsOn 是原专项的串行安排，只作为历史技术参考，不再叠加为第二套硬性调度约束。DW16 先交付通用 image/resource/cancel/recovery 机制，DW19 再接 compositor 消费者，DW30 最后补跨业务系统恢复；CS10/CS11 的跨消费者条目分别随相应包关闭，不要求先完成 compositor 才实现图像后端。DW12 的基础资产事务可以先完成，渲染型预览由 DW17 共同关闭；此类跨阶段必要接口在当前业务阻塞时提前实现，不等到正式阶段切换才补。任何被拆到其他责任包的条目必须保留 ownerPackage，当前包不能把尚缺结果标成完整交付。

+# 桌面 Blender 5.2 → Web：执行完整构建验证
+目标：UI 布局、样式和操作习惯完全对标本机桌面版；复用现有原生 UI/WASM，保留全部功能与旧交接残余，task/parent/nextTask 不变。状态：in_progress。
+1. 固定基线：记录桌面执行程序、源码、依赖、WASM、应用和 fixture 的版本/哈希；使用相同语言、主题、字体、缩放、窗口尺寸和场景生成可复现桌面与 Chromium 截图、UI 区域与操作记录。
+2. 完整构建：增量构建所有受影响依赖和 Blender WebEngine，链接 WASM，构建前端与 Worker；执行类型检查、单测和真实原生联通检查，逐项修复失败并复测，保存命令、退出码及构件哈希。
+前置顺序（用户追加）：构件/资源身份 → 服务头、CSP与跨源隔离 → Worker加载/就绪 → GPU设备与编译器资源 → Python/UI注册与场景 → 原生窗口/画布 → 首帧 → 视觉与操作对照。逐级准备并记录就绪证据；上一层失败时先修复该层，不重复下游验收。冷启动时延单独记录，不以延长等待判定性能通过。
+3. 主桌面：先解决工作区不可用及原生写出越界，再逐项对照启动、菜单、工具栏、状态栏、区域尺寸/分割/合并、窗口、主题、字体、图标、弹窗、提示和缩放；源生 UI 的缺口沿原 Blender 调用链接通。
+4. 全模块：按已有模块/工作流逐个覆盖全部工作区和编辑器、各模式、面板、属性与节点、搜索/F3、对话框及文件/资产浏览；每项绑定桌面源码/operator、Web 入口、相同 fixture 与视觉/交互证据，未实现项继续保留为失败或待办。
+5. 操作对标：覆盖鼠标/键盘、快捷键、焦点、选择、拖拽、导航、上下文菜单、模态操作/取消、撤销/重做、打开/保存/重开、崩溃恢复；比较操作效果、原生 Main 变化和 UI 状态。OCCT 保持几何内核出口，Three.js 仅显示。

+
+## 当前必须交付的功能
+
+操作者入口：长任务／文件替换／恢复的跨模块所有权。
+
+复用与修复：复用 G02、G04、G06 的生命周期和取消机制，补真实跨模块恢复断点及用户数据保护。
+
+实现交付条件：故障后保留最后 coherent 工程；所有包真实缺口关闭后才交 DW31 完整版本和用户使用，不能靠阶段计数宣称完成。
+
+## 最小上下文与依赖
+
+先读最新同业务 handoff，保留当前进行中的改动。按需读取 `docs/tasks/WBV2-P1424-001-desktop-completion/DW30.md` 的最小生产入口，随后只定位当前 operator/reader/context 源函数，不加载全计划。这里的安排不是认定上述功能都缺失：已有完整实现直接引用，余项才补代码。
+
+同一工作流按用户输入 → native operator/求值 → 资源/结果消费 → 适用 undo/save/reopen → 错误/取消实现。先处理影响数据、无法调用或没有结果的缺口，再处理仅性能改善；不要无限泛化生命周期或接口。
+
+依赖已有组件时直接复用；缺共享接口则在当前业务内修该最小依赖并记录原责任包。若前置暂未解决，本轮继续独立可实现子项，记录具体 source/function、影响功能和下一修复动作。不要把第一阶段全部完成作为本任务开始的条件，也不能把依赖缺失当作已完成。
+
+## 不扩张的完成边界
+
+当前入口及必要依赖全接通后，才报告该方向实现完成；同一分组其他任务不自动完成。后续同一分组访问时从原 DW 卡剩余真实功能选下一组，不重复已完成项。每次 remainingRoutes 必须列具体 operator/资源/用户结果，避免只写“完整桌面未完成”；全局其余残项保留在 remaining 和原责任包。

 ## 目标
 
-Close the audited gap between classified feature routes and real browser/server execution.
+只收口 B3 会话退出保存（恢复上一次会话）：原生退出写 quit.blend、持久化 ack 后再关闭、写入失败保留数据与恢复机会。现有实现只引用不重写。
+
+- 入口链：wm_init_exit.cc → web_engine_main_state.* → web_engine_api.cpp → web-engine.worker.ts → native-session-opfs.ts。
+- 断点：blender-5.2.0/source/blender/windowmanager/intern/wm_init_exit.cc:502（WM_exit_ex 内 quit.blend 写入处）。
+- 三段式缺口状态以 case plan 与最新 continuation 的 remaining/failureReason 为准；本卡只保留指针。
+- 下一源码路径：wm_files.cc、wm_init_exit.cc（worker 销毁段）、web-engine.worker.ts 销毁分支。
 
 ## 输入与范围
 
-- `tests/golden/WBV2/web-product-backlog.json`
-- `web/app/src/capabilities/blender-feature-route-catalog.json`
-- each pending task's owned paths
-
-## 验收
-
-- SERVER_NATIVE performs a real bounded HTTP Blender background job and returns a mutated blend
-- F3 loads typed operator properties on demand
-- browser-equivalent routes invoke existing browser workflows
-- verification remains incremental and behavioral evidence stays explicit
+- 指针：B1/B2 已闭合批次见各自 continuation；资产恢复细节与原始资产清单见 source-cases-20261028/original-asset-index.json 及 continuation-20261028-original-assets.json。
+- 当前 case plan：source-cases-20261028/blendfile_autosave/last-session-case-plan.json；当前交接：continuation-20261029-b3-exit-api-resume.json。
+- 候选保持 immutable；运行、桌面对照、Chromium 证据仍 NOT_CLAIMED。
 
 ## 失败边界
 
-- missing provider, malformed envelope, hash mismatch, timeout, cancellation and context-only operators fail closed
-- failed turns remain pending and never publish false completion
+quit 文件写入失败不得覆盖上一份恢复文件；持久化 ack 失败必须保留当前 Main；缺失、损坏、超限、并发 owner 和 backend session 失败 fail closed，不发布伪成功。
+
+## 验收
+
+- 本轮用户于 2026-11-01 明确确认“逐案例测试 → 修复 → 复测”，覆盖旧的实现期禁止验证限制；仅 Chromium，本地 WASM 与原生后端分别记录，交付发布候选与验收结论，不执行生产发布。
+
+正向恢复、持久化读回、失败保留、Main/history 保留各有独立 case 记录；层1 单 case 闭合才跑该条有界 Chromium 案例，结果写入 case validation 字段且仍 NOT_CLAIMED。
 
 ## 交付与回滚
 
-- results: `tests/golden/WBV2/product-migration/*-result.json`
-- aggregate: `tests/golden/WBV2-P1424-001/product-implementation-report.json`
-- rollback: stop the runner and preserve the last completed runtime task
+交付 continuation、case plan remaining 与必要 manifest/status；失败保留当前候选并停止依赖其结果的下游工作。
+
+## 小批次规则
+
+- 单次源码读取≤30行，修改≤2文件，增删合计≤10行；交接只写 continuationNotes。
+- 下一批只读本卡、最新 continuation 与最小源码窗口；不手工推进队列。

+
+入口复用 B1 的真实 Playwright 用例、原生 session、Vite 隔离头和候选 WASM。它不编译、不下载浏览器、不推进队列。运行环境需要 Linux `flock`、本机 Chromium、现有 Node 依赖；B1 还需要 Blender 可执行文件。
+
+```bash
+node tools/web/run-workflow-case.mjs --plan tools/web/workflow-cases/B1.json --candidate build_web_main_desktop/b1-context-readback-20261023 --out tests/golden/WBV2-P1424-001/my-b1-case --port 5288 --packaged
+```
+
+- `--check` 只检查本地构件、可执行程序和两个 fixture；不启动服务，不代表 HTTP 或业务通过。
+- `--production <file.blend>` 替换生产片段；`--blender <path>`、`CHROME_PATH` 指定本机程序。
+- `--packaged` 验证候选的实际 `app` 页面；不加此参数时使用当前前端源码和指定原生构件。两种模式及打包文件分别绑定输入身份，不互相冒充验收证据。
+- 原命令可直接续跑：输入、浏览器版本和产物 hash 一致的 PASS 自动复用；失败后的相同输入必须先查看原因，再显式使用 `--retry-failed`。
+- 每个 fixture 使用独立 `attempt-*` 目录，保存命令、状态、HTTP hash、Playwright JSON、日志、截图、trace 和下载文件。不要把需长期保留的数据放在 `web/test-results`。
+- 旧进程仍活着时拒绝重复运行；进程已经退出的中断案例保留旧文件，从新浏览器和原始 fixture 开始该案例。成功的前置案例不会随之重跑。
+- 顺序固定为 candidate/资源 → 本机运行环境 → 服务/HTTP 隔离与真实 JS/WASM hash → fixture 操作；最小案例失败即停止生产案例。
+- `PASS_SELECTED_TESTS` 仅表示配置选中的断言通过。`remainingGates` 保留未覆盖项目，`acceptance` 始终是 `NOT_CLAIMED`；仍由项目评估器和完整案例门禁裁定验收。
+- 实际案例批次结束后会自动调用 `evaluate-wbv2-completion.mjs --case-manifest <本批manifest>`；失败也会记录，日志在 `evaluation.log`。评估失败时保留案例产物并返回失败码，不能当作进度已发布。
+
+## 扩展 B2–B6
+
+B2 已提供 `tools/web/workflow-cases/B2.json`，覆盖现有 Canvas 确认/取消断言，其余门禁保持显式未覆盖。B3–B6 复制此配置，设置批次、业务描述、实际 operator/RNA/Main 源码路径与当前用例选择器；保留一份最小 fixture 和一份真实生产片段。
+
+用例必须从 `process.env.WBV2_CASE_FIXTURE` 读取输入，以 `testInfo.outputPath()` 保存输出。复用 `web/tests/fixtures/native-ui-workflow.ts` 观察 Worker 请求、读回和操作耗时；用源码定义的业务字段做断言。新增配置不会自动扩大验收范围，也不能用 `scope` 文案代替断言。
+重开脏工程时使用 `resolveProjectReplacement(page, 'cancel' | 'discard' | 'save')` 操作真实 React 对话框；浏览器 `dialog` 事件不能代替此步骤。重开后必须等到新的 Worker snapshot，再比较 Main 值，不能仅匹配原本就存在的 `SceneIR` 文本。
+Console 使用 `console-main-workflow.ts` 的最新结构化回执和递增序号；避免在累积输出中搜索旧坐标。对象名来自实际 fixture，先检查 location/translation 为有限数值三元组，再按明确容差比较 native/WASM 读回。
+原生 WASM Console 复用 `wasm-console-workflow.ts`：先等新 `pythonExec` 请求（10 秒），再按同一 requestId 等结构化返回（60 秒）；前端明确报错立即失败。`switchNativeWorkspace` 验证实际 Main 的 workspaceId 后才继续操作，禁止把按钮 click 完成当作原生切换完成。失败时用 `captureNativeWorkflowState` 保存最近请求、响应、编辑器上下文及 Console 输入/状态，不重放失败命令。
+属性读回先用 `showNativeObjectProperties` 准备对象上下文，再用 `expectUILocation` 检查实际 HTML 数字输入的 `valueAsNumber`、有限性和容差；Worker 坐标或 UI revision 不能替代可见字段。`performNativeAction` 按动作/操作/上下文匹配新请求并绑定回复，失败直接报告原生错误；观察器保留有界 `errorDetail` 堆栈，避免只剩笼统错误码。
+评估器输出 `currentCasesEligible` 表示本次案例的当前 hash 绑定通过数量；`workflow` 是原有整体工作流评估，不能把本次两案例通过等同于全局通过。
+计划可用 `sourceReview` 绑定经阅读确认的 operator/RNA/Main 契约。执行前检查每个源码/用例绑定 hash、契约来源和数据类型，漂移立即阻断；评审文件及绑定文件一并进入案例输入摘要。该记录只覆盖声明的案例行为，`verifiedUnitDelta` 固定为 0，不能据此增加整单元 parity 数量。数值 UI 断言使用 `spinbutton` 定位真实输入，预期值对应 RNA 的局部 location。
+原生 Canvas 案例继承共享 Chromium 的 WebGPU 参数；画布出现重试告警即停止依赖步骤。`native-modeling-workflow.ts` 观察真实模态起止并读取 bpy/BMesh；取消比较数据和撤销历史，帧 revision 可以因预览/回滚递增。`captureNativeWorkflowState` 同时保存有界浏览器错误。
+序列化差异可用 `compare-blend-id-fields.py before.blend after.blend --output report.json`；依赖 Blender 自带读取器及 python3-zstandard，可用 `--dependency-path` 指向本地依赖。工具按实际 DNAStruct 解析 ID 字段，报告块数量及输入 hash；DATA 地址不作为语义身份，结果不等于完整 Main 相等证明。
+
+fixture、源码、公共资源、用例、共享辅助代码、依赖锁、工具、浏览器版本任一变化，旧 PASS 不复用。需要新增外部依赖时，把相应实现/数据路径加入 `sourcePaths`。服务使用新实例和严格端口，避免连接旧候选。
+
+## 先确认真实类型，再比较
+
+Playwright 的 `stats.expected` 等字段是非负整数，`results[].status` 是字符串，`suites/specs/tests/results` 是数组。工具逐层检查类型；`"1"` 不会被当成 `1`，空报告、跳过、预期失败和重试不能算通过。
+
+Main 坐标先检查 `number` 与有限值，再按源码行为选择精确比较或明确容差；不能对所有浮点结果默认四舍五入。DOM 属性返回 `string | null`，版本号保持字符串比较，缺失属性应报错。字节数据识别为 Buffer/ArrayBuffer 后按字节或 SHA-256 比较。结构化状态使用深严格比较或显式业务字段比较，不用字符串包含关系判断 Main 是否恢复。
+
+工具测试：`node --test web/tests/unit/workflow-case.test.mjs`。这组测试验证工具的失败边界，不替代 Blender 功能验收。

+# 查看 Blender → Web Blender 当前执行状态
+
+在仓库目录运行：
+
+```bash
+python3 my-tools/view_wbv2_progress.py
+```
+
+每 5 秒自动刷新，按 Ctrl+C 退出：
+
+```bash
+python3 my-tools/view_wbv2_progress.py --watch
+```
+
+自定义刷新间隔和最近交接条数：
+
+```bash
+python3 my-tools/view_wbv2_progress.py --watch --interval 10 --recent 5
+```
+
+从任意目录执行：
+
+```bash
+python3 /home/mes123456/workinf_Blender_Wasm/my-tools/view_wbv2_progress.py --watch
+```
+
+获取 JSON（配合 --watch 时每行一个 JSON 快照）：
+
+```bash
+python3 my-tools/view_wbv2_progress.py --json
+```
+
+默认输出只保留当前任务真正需要的信息：
+
+- 当前任务、活动轮次、当前 UI 模块、进程身份、心跳和本轮实际耗时。
+- 当前调度器交接的下一动作与明确余项；旧的阶段清单、空模块零计数和历史计划不再冒充当前进度。
+- 最新源码交接及少量最近结果；每轮使用 `process.json` 的实际耗时，不用文件时间差估算执行速度。
+- 调度器指定的应用候选、明确待组合源码轮次和根会话补缺是否尚未归属候选；不扫描其它候选目录代替当前记录。
+- 当前 `validation` / `acceptance`；不以心跳、轮次、构建或报告数量宣称完整对标。
+
+需要历史路由、源码落点、进程文件和已报告实现条目时再展开：
+
+```bash
+python3 my-tools/view_wbv2_progress.py --details
+```
+
+该入口复用当前任务的 `unattended-implementation/state.json`、`desktop-delivery-manifest.json`、当前轮 `attempt.json`、少量最近 `result.json/process.json` 和显式根会话交接。候选只读取 `state.applicationCandidate` 指定的 `candidate.json`；不使用其它目录的修改时间替代，不读取 WASM 内容、不重新计算构件哈希、不载入完整源码 inventory。
+
+命令只读，不启动/停止服务，不更新队列、状态或缓存，不构建，不运行功能验证。状态文件缺失、暂时写入不完整或任务不一致时显示说明，不误报已完成。本次实现遵照项目规则未执行测试、独立语法检查或验收。

 Follow AGENTS.md: read the queue, print-task-context, check-task-context, then only named owned paths and bounded source searches.
 Drive this task by its business module, user workflow and concrete function routes, then the exact source/operator case matrix.
 FIRST search the supplied Blender 5.2 sources and task-scoped related references to resolve behavior before editing the Web implementation.
 Use node tools/web/search-wbv2-batch-source.mjs --unit <source-unit-id> --pattern <symbol> to read bounded native source locations.
+When sourceAnchors are present, start with their exact IDs and symbols; do not repeat a search without --unit if the task has no default source batch.
+Batch independent bounded reads in one tool round trip. Search symbols before opening large files; keep output bounded. Do not read old worker logs or rediscover known entrypoints.
+Limit each tool response to 2000 output tokens and each file excerpt to 80 relevant lines. Use --max-hits 12 for source searches. Do not cat App.tsx, WebEngineClient.ts, catalogs, inventories or full test files.
+Scoped worktree status is already provided. Never run repository-wide git status/diff; any additional Git inspection must pass exact owned/test paths after --.
 Blender 5.2 source/Main is authoritative. Never simulate Blender in JS or count route classification, timing, builds or bookkeeping as completed behavior.
 Preserve dirty files. Reconcile previous edits before changing code. Never replay an unknown generator or external write.
 Implement production code and executable focused tests, adding only directly related helpers/tests.

+CURRENT CONTEXT: {json.dumps(context, ensure_ascii=False, separators=(',', ':'))}
+
+Runner already supplies the queue, task context and parent records. Use the current handoff report and at most eight exact production entrypoints. Search Blender with node tools/web/search-wbv2-batch-source.mjs --source <exact-Blender-file> --pattern <text>; use --runtime for Web files. Do not load whole inventories, old worker logs, roadmaps or status history. Read only the relevant function ranges from interrupted work. Hard batch limits: each source window <=30 lines; each edit <=2 files and <=10 changed lines including handoff; use the configured investigation budget ({self.args.source_read_command_budget} reads / {self.args.implementation_progress_timeout} active non-build seconds) to resolve one missing edge; edit only when source evidence is sufficient. LOCATE_SOURCE remains read-only. If the edge already exists or remains uncertain, hand off the exact next dependency; never manufacture an edit to satisfy a read count or timer. Output only a short summary plus key fragments. End every batch with continuationNotes containing the exact breakpoint path/line, completed fact, remaining edge and next direct action; the next batch starts there and must not repeat a whole-repository search.
+The source search command requires an exact allowlisted file with --source or --runtime; never invoke it with --runtime alone, a directory, pattern-only query, or invented unit id. If the exact file is not in CURRENT CONTEXT.nextSourcePaths or a named source reference, use the supplied path first and keep the search bounded.
+
+Priority {priority}: {phase_instruction} {no_progress_warning}
+If integrationRetry.retryAt is still in the future, retain its blocker, pending edits, file ownership and old candidate; work on an independent unfinished route instead of repeating the blocked integration. Do not treat an unreleased foreground file as available or rebuild its partial inputs.
+Efficiency order: pending source batches are integrated before unrelated work; a
+delivery-only turn packages once and then ends. When pendingSourceCycles is empty,
+do not rebuild or repackage an unchanged candidate; select a new source-backed
+operation. Candidate generation, build time and service uptime never count as
+business progress.
+{integration_first if priority != 'LOCATE_SOURCE' else 'Locate only; artifact generation is not permitted in this phase.'}
+INTEGRATE_PENDING is a delivery-only turn: reuse a matching already linked pair or incrementally generate web_engine, package once with tools/web/build-main-desktop-candidate.py --output <new-directory>, write the exact candidate.json path in the final handoff, then END THE TURN. Do not start a new feature investigation after successful packaging. On failure repair the named dependency from source or hand off its exact error; do not rerun unchanged inputs. A partial archive is not a combined pair; later native edits remain pending. Packaging is not feature completion. In locate phase perform only bounded source tracing, no edits/build/package; report the exact missing edge or existing implementation with concrete next action.
+
+Return batchReadyForIntegration=true when this coherent user-operation family has complete source wiring and its remaining work is delivery to an application candidate; false for partial source work or unresolved source dependencies. This flag does not close a gap/focus or establish acceptance. Do not wait for six unrelated edits after a complete family. The parent schedules integration on this explicit request, six pending source batches, or pending work deferred across {CANDIDATE_MAX_DEFERRED_TURNS} turns. Preserve every unrelated residual and source question. If an unchanged build is blocked, repair its named source dependency before any retry.
+
+{phase_instruction} Recent same-stage source and handoffs supersede old missing/nextAction claims. An unverified existing route is not a reason to reimplement it. Reuse completed siblings. UI parity includes labels, grouping, enabled/visible/hover states, shortcuts and feedback; APIs alone do not finish a panel. Operators must be usable from normal UI without JSON/Python input. Keep all real residuals with their original owner. Same file != same completed workflow. Avoid unrelated refactors, generic GPU hardening and per-field microtasks. After two unproductive attempts, change the concrete source-backed repair strategy or implement another ready subroute, retaining the original unknown. Never edit merely to reset a timer.
+
+Native functionality must use original Blender/WASM; OCCT is the geometry kernel and Three.js only displays its output. Preserve native errors and resource ownership. No invented success, JS geometry simulation, stub, second implementation or streaming substitute. Reuse local artifacts before downloading/building dependencies. Node bake storage/find_bake ownership already lives in MOD_nodes_storage.cc; if relevant use tests/golden/{TASK}/nodes-bake-storage-implementation.md.
+
+Batch discipline: name the finite user-operation family, included adjacent actions, reused implementation and missing native edge before editing. Sharing a file or focus is insufficient to group unrelated work. Keep separate short UI-interaction and native-function residuals; a callable button does not establish complete desktop menu/region parity. Prioritize known data/recovery failures and blocked normal workflows. This worker is the assigned production writer; if overlapping external edits are discovered, stop your conflicting writes and hand off exact paths without overwriting, restarting services or changing control state. Distinguish healthy bounded build/resource waits, source blockers and provider backoff from repeated investigation without progress. Report concrete routes changed, source wiring, candidate inclusion and user acceptance separately; unknowns remain explicit, and cycles/builds/repackaging never count as new functionality. Use the current handoff over stale missing claims. Existing timeout, fairness, retry and no-validation rules still apply.
+
+Small-context rule: read only short source windows needed for the current call chain and cap command output and handoff summaries. Do not concatenate full files, long logs, or repeated history. When the read/output budget is reached, stop expanding context, record exact paths and the next action, and hand off to the next safe turn; avoid long-context compaction.
+
+Build only to generate required artifacts: incremental existing tree, fixed -j8, affected target first. Full link/package after a coherent family or {CANDIDATE_REFRESH_GAP} pending source batches. No clean/cache deletion, timestamp forcing, repeated unchanged builds or deployment. Redirect build output to this cycle log, return exit code and at most 24 distinct diagnostics. Never dump whole linker output. No tests, browser/smoke/regression, type/syntax/lint/context checks, screenshots, inventory/evidence audits or pass receipts during implementation. Preserve dirty changes; no reset/checkout/clean, commit/push, other agents/schedulers or persistent servers. Do not edit unattended control files or queue pointers.
+
+Investigation budget: after {self.args.implementation_progress_timeout} active non-build seconds and {self.args.source_read_command_budget} read commands without production changes, the supervisor may end the turn at a command boundary. Source-idle limit is {self.args.source_progress_timeout}s. Active artifact generation/provider reconnect have separate limits; shorter timers are not the objective. Keep reports concise and finish a coherent handoff before more exploration. A source change count is not feature coverage. Report provider limits as external errors, never bypass them.
+
+Write tests/golden/{TASK}/unattended-reports/cycle-{cycle:06d}.md with 处理模块 | 对标项 | 源码落点 | 路由入口 | WASM边界 | 状态 | 结论, exact changed production paths, grouped completed routes, concrete residuals and next direct call, plus a short continuationNotes paragraph. Keep validation=NOT_RUN, acceptance=NOT_CLAIMED. Do not update aggregate manifests. Return the provided JSON schema: build.status reflects commands actually run; artifactPaths includes exact candidate.json; not_run has empty log/artifacts/blockers. delivery.stageId={stage['id']}. Use exact supplied gap IDs in efficiencyReview.findings; inspected=false if no review was performed. nextSourcePaths contains up to eight exact paths. Remaining entries name '[ID] user operation -> function/resource -> missing behavior'; distinguish not implemented, unresolved source question, implemented-unverified and external blocker. Preserve broader ownership in remaining, never erase scope to claim completion. Whole-focus completion requires every assignment implemented with no actual residual; allRequestedImplementationComplete remains false while any requested UI/function remains. Compilation and heartbeats never prove completion. Return immediately after the final structured handoff.

+GUIDANCE = '''Continue one authorized Blender 5.2 -> Web Blender user-operation gap. Preserve task/parent/nextTask, all residuals and existing dirty source; no reset/clean/commit/push, second scheduler, control-file edits or deployment. NOT_RUN/NOT_CLAIMED: no tests, browser, syntax/type/context checks or evidence audits. Build only needed artifacts in the existing tree, -j8, no repeated unchanged builds.
+Runner already supplied EXECUTION_QUEUE, task context and current parent; do not reread them. Use the latest handoff, exact nextSourcePaths and focused search-wbv2-batch-source; pass only Blender files with --source and Web/runtime files with --runtime. No inventories, full files or historical logs. Each source window <=30 lines: start with4-8 lines and narrow after truncation. Search results default to1KiB with384-byte match windows; refine the exact pattern/path instead of repeating oversized reads. Each edit <=2 files and <=10 changed lines including continuationNotes. Record breakpoint, completed facts, residual and next direct action after each batch.
+CURRENT CONTEXT is already loaded. Read context.json only for an explicitly deferredField needed now; never reload supplied fields or prior worker logs. Respect unreleased foreground ownership. Preserve omitted scope by reference. Search syntax is node tools/web/search-wbv2-batch-source.mjs --task WBV2-P1424-001 --source <Blender-file> OR --runtime <Web-file> --pattern <exact-symbol> --max-hits 6; do not inspect the search tool itself.
+Before reopening an older missing/unlocated claim, reconcile it with rootRepair.resultPath, the latest foreground handoff; read only its relevant short section. Delivered implemented-unverified facts supersede older claims, not residuals. Record that manifest and the concrete remaining edge in continuationNotes; if already reconciled and unchanged, resume the edge without rereading. Never repeat completed traces/builds merely for missing verification. INTEGRATE_PENDING retains priority.
+Use original Blender/WASM callers and existing modules; OCCT is the sole geometry kernel, Three.js displays results only. Trace one immediate call chain in <=30-line windows within CURRENT CONTEXT.investigationBudget (readCommands / activeNonBuildSeconds); use eight reads / 120 seconds only if absent. Edit only a confirmed missing edge and return the final handoff. If unresolved, hand off the exact symbol/line and next bounded read. Preserve residuals; no JS simulation, stubs, duplicate implementations or edits merely to satisfy a timer. Never bypass external limits.
+Honor priority: LOCATE_SOURCE only traces the exact boundary; IMPLEMENT_FAMILY finishes one operation; INTEGRATE_PENDING reuses a matching linked pair or incrementally builds web_engine, packages once with tools/web/build-main-desktop-candidate.py, reports candidate.json, then ends. Never package incomplete native inputs. An active integrationRetry means retain pending/ownership/old candidate and work independently. Generated artifacts, service uptime and reads are not functional completion.
+If integrationRetry.active=false, its deadline has expired; retain the old failure as history and reconcile the named dependency before proceeding. Historical foreground-ownership prose alone does not establish a current owner. Honor any concrete live ownership restriction and name the actual blocking resource; never renew a wait solely because an expired retry object exists.
+Write a brief current-cycle report and continuationNotes with module, workflow, native/WASM route, changed paths, exact breakpoint and residuals. Emit schema JSON only as the final response, never as repeated progress messages. Build fields must reflect actual commands; not_run has empty log/artifacts/blockers. Set batchReadyForIntegration only for fully wired source awaiting delivery. Completion flags stay false while any owned gap remains; efficiencyReview.inspected=false unless performed. Reference broader scope locally and end after final handoff.
+Set delivery.stageId to CURRENT CONTEXT.stageId and nextSourcePaths to at most eight exact files; write the report to tests/golden/<task>/unattended-reports/cycle-<six-digit-cycle>.md. Keep UI labels, enablement, shortcuts, cancel/retry and native ownership aligned with Blender; classify actual missing edges separately from implemented-unverified routes. Full original guidance is preserved in prompt.source.txt; read only a needed paragraph, never reload the whole file.

+# Corrective Continuous Task Handoff
+
+This is the continuation entrypoint for the corrective execution plan. The
+authoritative legacy queue remains `docs/EXECUTION_QUEUE.md`; this file points
+only to the shadow corrective task and must never advance `M16-GAP-*`.

+| handoff next task | `C6-003` (post-write verification) |
+
+## Blocker
+
+The durable corrective checkpoint is `C6-003`: its dry-run and write-preview
+bytes match, the explicit owner review is recorded, protected legacy hashes were
+verified before the write, and the atomic queue write exited 0. The handoff is
+`in_progress` for post-write verification with `queueMutation=true`; the legacy
+queue now points to `M16-GAP-00277` and the rollback receipt is recorded. Do not
+run another queue write unless the post-write gates identify concrete drift.
+
+The completed predecessor handoffs (`C0-001` through `C5-003`, `C6-001`, and
+`C6-002`) remain immutable evidence. Their completion does not release the
+current G5 post-write verification gate.
+
+## Resume Prompt
+
+```text
+按 nextTask1.md 接续执行。
+
+激活 corrective continuous mode。只要用户消息要求“按 nextTask1.md 接续执行”、
+“继续执行”或等价含义，就先做只读 checkpoint recovery，再开始当前 Current
+Task；不要要求确认、不要只给计划。只有成功 handoff 才能自动开始下一轮；每轮
+完成一个 corrective task 后进入 fresh compact context，重新读取本文件的新
+Current Task。遇到阻塞、失败、环境缺失、预算耗尽、传输异常、闭合门或用户要求
+停止时立即停在当前 checkpoint，不得为了保持连续而越过门禁。
+
+每次请求的第一步固定为只读恢复（即使上一次请求只报告了 remote compact
+错误）：
+
+```bash
+node tools/web/print-task-context.mjs
+node tools/web/check-task-context.mjs
+git status --short
+jq '{task,status,queueMutation,nextCorrectiveTask,inputDigest,commandExitCodes}' \
+  tests/golden/corrective/C6-003/handoff.json
+```
+
+随后运行 `node tools/web/check-corrective-plan.mjs`。若 plan、task card、handoff
+的当前任务/状态/ready/next 不一致，或 handoff `status=blocked`，只记录精确
+阻塞并停止；不得重跑未知结果的生成、构建、保存或 queue-write 命令。恢复请求
+最多重试一次；再次出现 stream disconnect、error decoding response body 或
+remote compact 失败时保持当前状态并结束本轮。
+
+本文件只驱动 corrective shadow plan。`docs/EXECUTION_QUEUE.md` 是 legacy M16
+指针；两者不可混用。当前 corrective task、依赖、状态、ready 标志和下一任务只
+接受 `docs/BLENDER_WASM_CORRECTIVE_TASK_PLAN.json`、当前 task card 和最新
+durable handoff manifest（成功或阻塞）的交叉证明，禁止从历史编号或 Markdown
+猜测。
+
+每个 iteration 只完成一个 C0-C6 任务，并严格按以下顺序执行：
+
+1. 读取 `docs/EXECUTION_QUEUE.md`。
+2. 运行 `node tools/web/print-task-context.mjs`。
+3. 运行 `node tools/web/check-task-context.mjs`。
+4. 运行 `node tools/web/check-corrective-plan.mjs`。
+5. 只读取当前 C task card、其明确列出的输入和最小必要 fixture。
+6. 若当前 task 为 `planned`，在所有 preflight 通过后将当前 task/card 标记为
+   `in_progress`；若 handoff 为 `blocked`，保持当前 task/card 和 pointer 不变，
+   不得提前把任何 successor 标记为 ready 或修改 next pointer。
+7. 执行任务卡中的真实命令，把长日志写入
+   `tests/golden/corrective/<task>/`，并记录每个命令的退出码。
+8. 完成 focused、negative、persistence、hash、determinism 和 governance gate。
+9. 在所有 evidence 文件最终化后运行 `node tools/web/write-corrective-handoff.mjs`，更新该任务的
+   `handoff.json` 和 `manifest.json`；同时更新该 C task 的 status 文档。
+   handoff 命令不要用会在 hash 扫描后再次截断/写入同一个日志的重定向；若日志
+   属于 evidence，先写完日志，再运行 handoff，handoff 完成后不得再编辑 evidence。
+10. 校验 handoff 的 artifact SHA-256、`inputDigest`、`queueMutation`、
+   `nextCorrectiveTask` 和命令退出码。dry-run、write、handoff 三者的
+   `inputDigest` 必须一致。
+11. 只有 handoff 完整成功且所有必需 gate 通过后，才将当前 task 标记为 `done`，
+   仅按 handoff manifest 的 `nextCorrectiveTask` 从依赖图选择 successor；为
+   successor 创建/校验 task card，并将唯一 successor 标记为 ready。若 handoff
+   为 `blocked`，只更新本文件的 durable checkpoint 字段并保留同一 current task，
+   不创建 successor、不推进 pointer。成功 handoff 后再更新本文件 Current Task
+   表，重新执行第 1-4 步，开始下一 iteration。
+12. 任何状态迁移、task card、plan 或 Current Task 更新都必须由已通过的 handoff
+   支持；禁止先改指针再补证据。
+
+下一任务只能来自 corrective plan 的依赖图，不能猜测。
+
+严格遵守以下边界：
+
+- C0-C5 期间禁止修改旧 M16 queue、parent manifest、completion registry、
+  catalog、index、旧 M16 task card 和历史 evidence；corrective task card 只可
+  按本协议在对应 handoff 前后更新生命周期。
+- 禁止手工推进 legacy `nextTask`、offset、completion 状态或 parent pointer；
+  corrective lifecycle 和 `nextCorrectiveTask` 只能由通过 handoff 的 evidence
+  与 corrective dependency graph 支持。
+- `queueMutation` 必须保持 `false`，直到 C6-003 且 G5 通过。
+- `--write` 只能写入明确的 corrective staging 目录，不能覆盖正式生成物。
+- 不得把 `CANCELLED`、`UNSUPPORTED`、`EXTERNAL_REQUIRED`、metadata-only、
+  snapshot/read-only 或 negative-only evidence 当作正向功能完成。
+- 浏览器验收永久只使用 Chromium；禁止 Firefox 和 WebKit。
+- 不要删除、重置或回滚用户已有改动；失败证据必须保留。
+
+任何命令失败、hash drift、plan/index/catalog/queue 不一致、parent pointer
+失配、digest 不一致、预算异常、环境缺失、传输异常或 gate 阻塞，都立即停止
+自动迭代；当前 task 保持 `in_progress`/`blocked`，不得创建 successor handoff，
+保留失败证据并报告精确路径。不得用重跑覆盖失败日志来伪造通过状态。
+
+当前从 `C6-003` checkpoint 恢复。`C0-001` 至 `C5-003`、`C6-001` 和 `C6-002`
+的 handoff 均已完成；明确的 owner review 已记录，queue write 已完成，
+`M16-GAP-00277` 现在是唯一 active legacy successor。
+
+上下文大小必须按仓库预算管理：每个 iteration 只保留当前任务卡、parent
+manifest、parent status、`print-task-context` 输出和任务卡列出的最小输入；不要
+把完整 `next-task-plan.json`、全部 `docs/status/`、历史 transcript、完整 parity
+ledger 或长命令日志带入上下文。默认上下文上限约为 3,500 tokens，serialized
+context envelope 上限为 1,024 tokens；先运行 `check-task-context`，只有报告
+`withinBudget` 才能继续。大 JSON 使用 `jq` 读取指定字段，大日志使用 `sed`/`tail`
+读取窄范围；完整日志只保存在 evidence root，不复制到对话中。每个命令返回后只
+保留退出码、关键摘要、证据路径和 hash。
+
+每次 handoff 后开始 fresh compact context：丢弃上一轮长输出，下一轮只从新 manifest 的
+`nextCorrectiveTask`、status、evidenceRoot、commandExitCodes、sourceHashes、
+`inputDigest` 和 `queueMutation` 恢复，不依赖上一轮对话。若上下文接近预算，先
+停止读取、写入摘要并重新运行 `print-task-context`；不得用扩大读取范围来解决预算
+问题。若 compact、resume 或传输发生异常，先检查已有日志、manifest 和 hash，
+从第一个缺失步骤继续；不要盲目重复成功的写入或推进指针。
+```
+
+## Context Budget Protocol
+
+每轮执行前必须建立最小上下文，并把上下文治理本身视为 gate：
+
+1. 只读 `docs/EXECUTION_QUEUE.md`、`print-task-context` 输出列出的文件，以及当前
+   task card 的 `inputPaths`、`commands` 和 `exitCriteria`。
+2. 先运行 `node tools/web/check-task-context.mjs`；`withinBudget=false`、
+   `estimatedContextTokens > 3500` 或 `envelopeTokens > 1024` 时保持当前任务不变，
+   缩小读取范围后重试。
+3. 不打开完整 `next-task-plan.json`、全部历史 status、完整 generated report、
+   完整 git diff 或完整命令输出；需要判断时用 `jq -e/-r` 提取字段、用
+   `sha256sum` 校验来源、用 `rg` 定位小节。
+4. 将长输出直接写入 `tests/golden/corrective/<task>/`，对话和下一轮上下文只保留
+   `exitCode`、一行结果、报告路径、artifact count/hash 和失败原因。
+5. 一个 iteration 结束时，必须形成可独立恢复的 compact handoff：
+   `task`、`status`、`gate`、`evidenceRoot`、`commandExitCodes`、`sourceHashes`、
+   `inputDigest`、`queueMutation`、`nextCorrectiveTask`。
+6. 下一 iteration 丢弃上一轮的临时解释和长日志，只读取该 handoff 及新任务卡；
+   不把完整历史 transcript 作为隐式输入。
+7. 出现 compact/remote transport error 时，停止自动推进，按 Resume Prompt 的
+   只读顺序检查磁盘上的证据和 handoff；只在 checkpoint 明确显示某命令缺失且
+   不存在未知状态时重跑一次，确认 digest/hash 后再继续。不得用旧 transcript
+   或完整日志填充下一轮上下文。
+
+## Iteration Contract
+
+1. Run `node tools/web/print-task-context.mjs` and
+   `node tools/web/check-task-context.mjs`.
+2. Run `node tools/web/check-corrective-plan.mjs` before editing.
+3. Read only the current C task card and its named inputs.
+4. Keep all corrective outputs under `tests/golden/corrective/<task>/`.
+5. Before and after every task, compare the protected legacy source hashes; a changed
+   protected hash is a hard stop, not a reason to re-sign history.
+6. A task is complete only when its card's commands, evidence hashes, deterministic
+   output check, handoff fields, and all gates pass.
+7. Run `node tools/web/write-corrective-handoff.mjs` only after all evidence files
+   are final; do not add or edit evidence afterward without regenerating the handoff.
+8. Update this file only from a durable successful or blocked corrective handoff. The
+   current value and any successor come from the handoff manifest and corrective plan
+   dependency graph, never from a guessed legacy task number. A blocked handoff may
+   refresh the checkpoint fields but must keep the same task and pointer.
+
+## Stop Rules
+
+- Never run a queue-writing command before `C6-003` and `G5`.
+- Never count `CANCELLED`, `UNSUPPORTED`, `EXTERNAL_REQUIRED`, metadata-only, or
+  negative-only evidence as positive parity.
+- Never edit `docs/EXECUTION_QUEUE.md`, legacy `next-task-plan.json`, task
+  catalog/index, parent manifest, parent status, or legacy task cards as part of
+  C0-C5. Corrective cards and shadow plan state may change only after the
+  preflight/handoff rules above are satisfied.
+- Stop on the first failed command or inconsistent hash; keep the current task
+  `in_progress`/`blocked` and preserve all evidence.
+- `owner_review_required` is cleared by the recorded review artifact; any post-write
+  hash or pointer drift remains a hard stop and requires rollback receipt review.
+
+## Handoff Fields
+
+Completed handoffs: `C0-001` through `C5-003`, `C6-001`, and `C6-002` are `done`.
+The current evidence is under `tests/golden/corrective/C6-003/`; its handoff is
+`in_progress`, with `queueMutation=true` and `nextCorrectiveTask=C6-003` while
+post-write G5 verification remains active.
+
+After each successful iteration, record `task`, `status`, `gate`, `evidenceRoot`,
+`commandExitCodes`, `sourceHashes`, `queueMutation`, and `nextCorrectiveTask` in the
+task's machine-readable handoff. Then replace the Current Task table above with the
+new corrective task before starting the next iteration.

+4. 使用 Unparent 后核对对象世界位置；复杂层级先保存副本。
+
+
+### 原点和变换
+
+1. 选择单个对象，记录位置、旋转和缩放。
+2. 按需求使用“应用变换”或“原点到几何体”；这是改变对象数据或变换关系，不只是切换显示。
+3. 核对视口、对象通道及保存后的结果，再决定是否继续后续建模。
+
+
+核对：
+- rotation-parent.blend 的局部/世界矩阵与桌面参考一致。
+- 实际业务工程要分别验证集合成员、父子名称和世界位置。
+

+3. 下一次执行 counter += 2，然后 print(counter)，应输出 42。
+4. 可使用 bpy、C、D、Vector、sin、pi 等桌面控制台常用默认名称；表达式结果可通过 _ 读取。
+
+
+### 理解异常与继续操作
+
+1. 运行时若出现普通 Python 异常，界面显示 PYTHON_ERROR，但会话保持 READY，可以继续执行。
+2. 异常前已完成的 bpy 修改会保留并回写；局部变量和对象引用也保留。异常不是自动回滚。
+3. 语法错误不会执行该段代码；修正语法后直接 Execute。
+4. SystemExit 和 KeyboardInterrupt 会显示错误并允许继续输入；不要把它们当作关闭服务的方法。
+
+
+### 会话与 Web 编辑的关系
+
+1. 在 Web 侧另做修改、撤销或重做后，旧原生会话可能过期。点击 Reset Session 以当前场景重新连接。
+2. 出现 SOURCE_CHANGED / RESET_REQUIRED 时，保存当前 Web 场景并重新 Connect，不能强行提交旧会话。
+3. 用完点击 Disconnect / Stop，释放原生会话资源。
+
+
+核对：
+- counter 跨命令保留；普通异常后可以继续访问同一个对象引用。
+- 场景外部修改时旧会话不会覆盖最新 Web 场景。
+
+边界：
+- 原生进程退出、传输失败、输出超限或结果保存失败仍会重置会话，见 M36。
+- 刷新页面或 Reset Session 不是保留 Python 局部变量的操作。
+
+
+## M28 文本脚本与批处理

+
+
+### 脚本文件与错误
+
+1. 可在 Open .py 选择脚本文件，检查内容后执行。
+2. Run Script 为一次性批处理；需要跨命令变量时使用 M27 的持久控制台。
+3. 批处理失败时查看输出与诊断，修正后重新运行；不要假设失败前的修改已写回 Web。
+
+
+核对：
+- 成功执行后对象 X=2，保存后桌面读回正确。
+- 运行前明确所用对象名称与上下文。
+
+边界：
+- 批处理采用成功后回写策略；其异常语义仍不同于桌面 Text Editor 中已经修改当前场景的行为。
+- 只在受信任的本机环境运行需要的脚本。文件写入和外部访问受原生任务隔离边界约束。
+
+
+## M29 真实原生桌面与交互式工具

+
+
+核对：
+- 确认移动后 X=1；取消移动后 X 保持原值。
+- 每次提交都作用于开始会话时的同一项目修订。
+
+边界：
+- 这是原生 Blender 交互面板，尚未把全部桌面布局和导航状态同步为 React 编辑器状态。
+- 同时存在会话数和超时边界；中文输入法、剪贴板、复杂设备输入等没有完整桌面等价保证。
+
+
+## M30 资产目录、链接库与追加

+3. 点击 Mark Asset，再点击 Save Catalog。
+4. 确认未保存状态被正确标记，保存重开并核对目录与资产信息。
+
+
+### 链接与追加的前提
+
+1. 链接与普通追加有不同的数据所有权：链接数据可能禁止直接修改。
+2. Web 的 Append to Main 入口需要 Source .blend 和对应 Binding JSON；没有有效绑定文件时不要任意构造或跳过检查。
+3. 需要完整文件浏览器方式的 Link/Append 时，进入原生桌面，确保源文件可在任务资源中访问，再按桌面 File 菜单操作。
+4. 完成后核对库路径、对象归属和是否需要 Override，并交付配套库文件。
+
+
+核对：
+- 资产标记和目录经保存重开保留。
+- 业务链接工程应额外验证依赖链和重新加载。
+
+边界：
+- 本章直接实测资产目录；任意链接库、嵌套依赖和完整 Override 操作尚未全覆盖。
+
+

+2. 在 Web 打开工程，按 M13 同步相关文件和相对路径。
+3. 核对体积名称、帧号、显示状态及实际视口内容；切换帧时确认不是重复旧帧。
+4. 最终外观通过原生渲染对照，保存工程并验证资源仍可定位。
+
+
+核对：
+- 体积资源加载、页反馈、恢复和渲染由原自动化集合提供有限覆盖。
+- 实际业务样例须记录网格名称、分辨率、范围、帧序列和内存用量。
+
+边界：
+- 本轮没有为任意生产体积项目提供完整用户步骤实测截图；不能从自动化小样例推广到所有格式、压缩和缓存组合。
+
+
+## M33 GLB 导出及其他交换格式
+
+桌面对应：File Export / Import
+
+Web 入口：顶部“导出 GLB”；F3 与当前格式入口

+### 键盘使用
+
+1. 使用 F3 打开搜索，输入关键词；用 Escape 关闭。
+2. 输入数值或脚本时确认焦点位于目标输入框，避免快捷键作用到视口。
+3. 缩小窗口后检查主要按钮仍可访问；必要时滚动对应面板。
+4. 原生快捷键需要原生画面获得焦点且鼠标位于正确编辑器，见 M29。
+
+
+核对：
+- 对话框关闭后焦点可返回，继续编辑不应误触其他工具。
+
+边界：
+- 本轮有 960×844 紧凑布局流程；不代表所有手机、触控、IME 或辅助技术组合已完成验证。
+
+
+## M35 一个可重复的建模到渲染练习
+
+桌面对应：Modeling → Material → Camera → Render → Save
+
+Web 入口：综合使用 Web、Scripting、Rendering

+1. 打开 parity_scene.blend，保留原样例副本。
+2. 选中 ParityCube，按 M29 在原生桌面做一次移动并 Apply to Web Scene；或者用 M28 的脚本明确设置位置。
+3. 核对 Transform，不用视口观察角度替代相机构图。
+4. 按需调整已提供的材质和灯光参数，保存一个新的 .blend。
+5. 进入 Rendering，选择 CYCLES、PNG、帧 1，执行 Render Frame。
+6. 下载渲染图，确认主体、光照和构图；再重新打开保存的 .blend，重复同参数渲染作比较。
+7. 记录所用样例、参数、结果文件和任何差异。
+
+
+核对：
+- 数据修改、保存文件和最终图片三者一致。
+- 场景与资源可从保存结果恢复，不依赖当前浏览器中的临时预览。
+
+边界：
+- 这个综合练习由已测步骤组成；用户自己的复杂组合仍需要逐项验证。
+
+
+## M36 错误恢复与用户验证记录
+
+桌面对应：Reports、Undo、Recover、Reopen
+
+Web 入口：状态栏、Python 输出、诊断导出、Recent
+
+练习文件：samples/parity_scene.blend
+
+
+### 识别错误类型
+
+1. 普通控制台 PYTHON_ERROR：检查已执行修改，修正代码继续；需要回退时先在 Web 撤销，再 Reset Session。
+2. RESET_REQUIRED、进程退出或输出超限：当前 Web 场景受保护，重新 Connect 后继续。
+3. SOURCE_CHANGED：保留最新 Web 编辑，放弃旧会话的过期提交并重连。
+4. RESOURCE_HASH_MISMATCH 或缺失资源：清除损坏副本，按正确路径重新同步；不要把旧结果当作本次输出。
+
+
+### 记录并复测
+
+1. 发现问题时先保存当前可用工程副本和必要资源。
+2. 记录模块编号、输入文件、对象、模式、操作顺序、预期与实际结果。
+3. 保存 PNG 和诊断文件；如果有下载产物，附上原文件而非只附截图。
+4. 用同一输入重做步骤，确认是否稳定复现。
+5. 按 verification-checklist.csv 填写 PASS、FAIL、BLOCKED 或 NOT_RUN；不把没做过的操作记为通过。
+
+
+核对：
+- 修复后需重新执行实际失败步骤，再保存并重新打开验证。
+- 原生崩溃和输出超限不会把未确认修改覆盖到 Web 场景。
+
+边界：
+- 本手册不是全功能等价证书。无法从现有证据证明的功能仍按未验证处理。

+## 界面与桌面菜单组织
+
+1. 打开 http://127.0.0.1:5210/。顶部保留文件、编辑、渲染、窗口、帮助和工作区。
+2. 三维视图头部使用模式菜单，以及视图、选择、添加、物体等实际菜单。原长排按钮默认收起。
+3. Robot 是 Web 扩展，不是桌面默认工作区。窗口 → Web 扩展提供机器人和原生桌面会话。
+4. 工作区列表可访问被窄屏隐藏或滚动到屏幕外的工作区。
+5. 灰色命令没有等价 Web 入口，界面列出限制；不把名称出现当作功能完成。
+
+## 文件：新建、打开与恢复
+
+1. 文件 → 新建 → 常规，确认后加载本机 Blender 源码自带的 startup.blend，包含 Cube、Camera、Light。
+2. 新建确认前可以取消；当前未保存内容会提示。确认后替换当前工程。
+3. 文件 → 打开，或 Ctrl+O，选择工程/受支持模型文件。
+4. 文件 → 最近打开可恢复已保存项目；文件 → 恢复 → 恢复自动保存使用现有浏览器项目恢复机制。
+5. 浏览器本地存储、下载文件和桌面文件系统并非同一保存机制；重要工程仍应下载备份。
+
+## 文件：保存、另存为和导出
+
+1. 文件 → 保存沿用当前平台保存与下载流程，快捷键 Ctrl+S。
+2. 文件 → 另存为或 Ctrl+Shift+S，填写文件名并确认；下载位置由浏览器决定。
+3. 文件 → 导出 → glTF 2.0 (.glb) 导出当前场景。GLB 已从错误的渲染菜单归类移走。
+4. 机器人单独导出仍使用 Robot 工具中的“导出机器人 GLB”，避免将其他场景对象混入。
+5. 文件 → 追加/链接进入已有资产库工作台；它的绑定 JSON 和资源要求尚不同于桌面完整文件浏览器。
+
+## 编辑与未保存状态
+
+1. 添加 → 网格 → 立方体，检查对象数增加。
+2. 编辑 → 撤销，确认新增对象移除；编辑 → 重做，确认恢复。
+3. 编辑 → 重命名活动项或 F2，输入名称并确认。
+4. 编辑 → 菜单搜索打开 F3 搜索入口。
+5. 编辑 → 偏好设置目前只提供 Web 界面设置，不代表桌面完整 Preferences、插件管理和快捷键配置。
+
+## 模式和编辑模式菜单
+
+1. 选择网格，点击 Object Mode → 编辑模式。模式按钮为菜单，不再是简单的两态切换。
+2. 头部出现网格、顶点、边、面、UV 等菜单。选择面选择图标，然后选择 → 全部。
+3. 面 → 三角化，检查拓扑统计变化，保存后重新打开确认结果。
+4. 切回 Edit Mode → 物体模式。选择相机时，编辑模式和雕刻模式禁用。
+5. 姿态模式只对骨架开放。完整顶点/权重绘制模式、曲线编辑器全部桌面菜单仍未完成等价移植。
+
+## 添加与对象操作
+
+1. 添加 → 网格提供立方体、平面、球体、柱体、锥体和环体。
+2. 添加 → 曲线/文本/骨架/空物体/相机/灯光由 Web 平台的原生服务执行真实 Blender 操作。
+3. 物体 → 复制对象、链接复制、重命名、删除作用于活动对象。
+4. 物体 → 父级 → 设定父级：本入口要求选择两个对象，最后选中的活动对象作为父对象，另一对象作为子对象。
+5. 物体 → 应用 → 全部变换、设置原点 → 原点到几何体、合并和集合操作接入现有 Main 编辑命令。
+6. 物体 → 变换中的移动、旋转、缩放通过真实原生上下文面板启动交互工具，完成后需 Apply to Web Scene。这不是已完全内嵌的桌面视口操作。
+
+## 渲染图像与动画
+
+1. 渲染 → 渲染图像或 F12，自动进入 Rendering 并按场景引擎输出真实图片。
+2. 渲染 → 渲染动画或 Ctrl+F12 使用场景起止帧；原生服务仍有帧数和资源上限。
+3. 等待 SUCCEEDED，检查预览并下载结果。查看渲染结果进入 Rendering 工作区。
+4. GLB 是模型交换文件，不属于渲染菜单。渲染音频等缺失功能仍明确禁用。
+
+## 视图与选择菜单
+
+1. 视图 → 视角 → 前/后/左/右/顶/底调用既有导航，不修改模型变换。
+2. 视图 → 框显所选、显示全部、透视/正交及缩放使用同一导航控制器。
+3. 选择 → 全部/无/反选在物体模式作用于对象，在网格编辑模式作用于当前选择域。
+4. 画布获得焦点时可使用 A、Alt+A、Ctrl+I。输入框和对话框不会执行这些快捷动作。
+
+## 窗口、工作区与 Web 扩展
+
+1. 窗口 → 下一个/上一个工作区按已提供的工作区顺序切换。
+2. 工作区列表显示全部工作区，当前工作区有勾选状态。它不是任意新增桌面工作区的实现。
+3. 窗口 → 切换全屏使用浏览器全屏；新建窗口打开独立浏览器标签/窗口，不共享同一个桌面 Main。
+4. 显示状态栏复选项立即生效；保存视口截图下载当前主线程画布 PNG，不是完整操作系统截图。
+5. Web 扩展中的快捷操作栏可以显示旧的紧凑命令按钮，默认关闭以避免挤占桌面式头部。
+
+## 帮助、禁用项与键盘
+
+1. 帮助中的使用手册、导航说明和机器人工具说明打开应用自带 PDF，不依赖外部 CDN。
+2. 菜单用上下方向键移动焦点、右方向键进入子菜单、左方向键返回、Escape 关闭并返回触发按钮。
+3. 子菜单采用有返回项的分级面板，避免窄屏溢出；这与桌面的级联悬浮布局仍有差别。
+4. 撤销历史、完整首选项、若干模板和导出格式等没有等价实现的命令为灰色，不能把其显示计为完成。
+
+## 窄屏与后续验证
+
+1. 窄屏不再隐藏文件等主菜单。菜单使用独立浮层，避免被顶栏的 overflow 裁剪。
+2. 工作区可通过列表切换；部分辅助工具隐藏时仍可从菜单访问。
+3. 验证菜单功能时记录对象、模式、操作前后计数、保存结果和错误状态，而不是只检查菜单标题。
+4. 本轮只对齐截图涉及的顶部/三维视图头部及其主要业务入口。完整桌面全部编辑器布局、全部菜单和全部功能尚未一致。

+# Web Blender 六轴机器人工具操作使用说明书
+
+
+## 01 入口与运行准备
+
+1. 使用本机 Chrome 打开 http://127.0.0.1:5207/，等待底部引擎显示 ready。
+2. 点击顶部工作区左侧 Robot 按钮，打开“六轴机器人”工具。也可以按 F3 搜索“六轴机器人工具”。
+3. 首次使用可以不打开 .blend。空项目导入时，工具自动建立起始工程，再导入机器人；已有工程则保留现有对象。
+4. 窗口分为模型与资源、装配与检查、关节姿态、保存与导出四段；右侧工具内容可以上下滚动。
+5. 需要重新启动本轮服务时，在项目根目录运行 node user-testing/WEB_Blender_Robot_Tool_20260916/scripts/serve.mjs。
+
+核对：工具显示“等待输入”。未导入或未检查时，相关后续按钮不可用。
+
+
+## 02 加载内置 ABB IRB120 样例
+
+1. 点击“加载 ABB IRB120 样例”，等待状态显示“资源就绪”。
+2. 核对模型名 abb_irb120_3_58，10 个 link/frame、7 个 STL、6 个转动轴。内置资源按来源清单核对哈希。
+3. 无需进入 Scripting，也无需选择 .py 文件或逐条填写资源路径。
+4. 该型号为 ABB IRB 120-3/0.58，不是 IRB 1200；默认状态为 URDF 零位。
+
+核对：“导入零件”按钮可用；加载样例本身不会修改场景。
+
+
+## 03 导入零件
+
+1. 点击“导入零件”，等待状态从“正在导入零件”变为“零件已导入”。
+2. 工具通过 Web 平台原生服务执行真实 Blender STL 导入，创建 link 坐标节点与可视网格，颜色来自 URDF。
+3. 此时零件尚未按关节原点完整装配；不要把导入阶段重叠的零件视为最终姿态。
+4. 已有项目的对象和已上传资源保留。若项目中已有本工具机器人或存在同名对象，操作会拒绝，不覆盖原内容。
+5. 需要停止时，在原生操作进行期间点击“取消操作”；取消后可重新导入。
+
+核对：“建立 URDF 层级”可用；“导出机器人 GLB”仍不可用。
+
+
+## 04 建立 URDF 层级
+
+1. 点击“建立 URDF 层级”，等待“层级已建立”。
+2. 在关节表核对 joint_1–joint_6 的父级、子级和轴；固定的 base、flange、tool0 坐标系也保留。
+3. 模型根节点为 Robot_abb_irb120_3_58。链路为 base_link → link_1 → link_2 → link_3 → link_4 → link_5 → link_6 → flange → tool0。base 是 base_link 的固定子节点。
+4. 每个 link 的可视网格是该 link 的子节点，关节枢轴不通过合并网格丢失。
+5. 关闭工具后可在 Outliner 展开或折叠层级。需要回到工具时点击 Robot，再点击“读取项目机器人”。
+
+核对：关节姿态输入出现，“检查六轴”可用。层级创建不等于六轴检查已经通过。
+
+
+## 05 六轴联动检查
+
+1. 点击“检查六轴”，等待“六轴检查通过”。
+2. 工具先检查节点存在、父子关系、局部原点与当前姿态，再分别在限位内测试六个转动关节。
+3. 每轴通常测试 0.25 弧度，接近限位时自动选取允许的方向和幅度；记录后代世界矩阵是否变化。
+4. 每个检查动作结束后恢复原姿态。检查不会把机器人留在临时测试角度。
+5. 确认六个转动关节均为 PASS。固定关节行显示 --，并不表示遗漏了六轴检查。
+
+核对：全部通过后“导出机器人 GLB”才启用。任何失败都应先修正或重新读取，不得使用旧 PASS。
+
+
+## 06 调整关节角度
+
+1. 在“关节姿态”中找到 joint_2。使用滑块，或在数值框输入 30；界面单位为度。
+2. 点击“应用关节角度”。仅改变输入框不会立即修改场景，也不是实时拖动关节。
+3. 等待“姿态已应用”，查看机器人姿态；关节数据按 URDF 轴向由原生 Blender 更新。
+4. 姿态修改后必须重新点击“检查六轴”，通过后才可导出当前姿态。
+5. 点击“恢复零位”可将六个关节角度恢复为 0，再执行六轴检查。
+
+核对：30 度姿态和零位导出的 link_2 矩阵应不同；恢复零位后原点和层级不变。
+
+
+## 07 限位越界与错误恢复
+
+1. 关节数值必须在 URDF 的 lower/upper 限位内。若手动输入超限数值，点击应用会显示具体关节错误。
+2. 失败结果不回写 Web 场景；当前有效姿态保留，导出按钮禁用。
+3. 点击“读取项目机器人”刷新界面，再输入有效角度并应用，或点击“恢复零位”。
+4. 再次执行“检查六轴”，确认六项 PASS 后继续保存或导出。
+
+核对：不能因为输入框出现一个数字就认定该姿态已经写入模型。
+
+
+## 08 导出带层级 GLB
+
+1. 在六轴检查通过后，滚动到“保存与导出”，点击“导出机器人 GLB”。
+2. 浏览器下载 abb_irb120_3_58_hierarchy.glb；界面显示导出文件名、SHA-256、节点数和网格数。
+3. 导出仅包含工具管理的机器人子树；同一项目中的其他对象不混入这个专用导出。顶部通用 GLB 按钮仍是整个场景的通用导出入口。
+4. GLB 保留 link 节点、父子结构、局部枢轴与当前姿态，单位为米，坐标为 glTF Y-up。
+5. URDF 使用 Z-up，转换为 GLB 时坐标对应为 (x,z,-y)。不要在目标软件中重复执行同一次坐标转换。
+
+核对：零位样例应有 18 个节点、7 个可视网格，6 个转动轴和 3 个固定关系。
+
+
+## 09 下载关节映射和 URDF
+
+1. 点击“下载关节映射”，保存 abb_irb120_3_58_joints.json。
+2. 该 JSON 包含关节名称、父子 link、类型、URDF 轴、GLB 轴、限位、当前角度和最近检查结果。JSON 中角度单位是弧度。
+3. 点击“下载 URDF”，保留原展开 URDF 作为可追溯定义；它仍引用原 STL 包路径。
+4. 将 GLB、JSON、URDF 一起交付。普通 glTF/GLB 不完整定义关节限位、机器人动力学或 IK 控制器。
+5. 若目标机器人平台需要碰撞网格、惯量或控制配置，仍需使用 URDF 及该平台自己的配置。
+
+核对：不要把“GLB 有层级”误认为“GLB 已包含完整机器人控制系统”。
+
+
+## 10 保存工程与重新打开
+
+1. 点击“保存机器人项目”，等待浏览器下载 .blend。
+2. 此操作沿用平台项目保存流程，保存整个工程及机器人元数据；不是只保存当前工具窗口。
+3. 后续刷新或重新打开软件时，使用顶部“打开 .blend”选择保存的工程。
+4. 打开 Robot 工具，点击“读取项目机器人”，恢复模型、层级状态和已应用角度。
+5. 重新执行“检查六轴”后再导出，不能直接沿用前一次会话的检查状态。
+
+核对：已保存的机器人几何与元数据不要求用户重新执行导入脚本。
+
+
+## 11 已有项目恢复与撤销重做
+
+1. 打开保存过的机器人 .blend，再打开 Robot，点击“读取项目机器人”。
+2. 若项目不存在本工具元数据、同时含多个工具机器人或节点已删除，会明确拒绝读取或检查。
+3. 工具执行的原生场景写入沿用平台撤销历史。关闭工具后可使用顶部撤销/重做。
+4. 场景经过外部编辑、撤销、重做或重开后，重新读取并检查；工具用场景内容哈希防止导出过期结果。
+
+核对：恢复后六轴可再次检查并生成与当前项目一致的 GLB。
+
+
+## 12 导入自己的 URDF 与 STL
+
+1. 选择已经展开的 .urdf 或 .xml。当前不在平台执行 Xacro，需先展开后提供。
+2. URDF 必须是单根无环树，恰好六个转动关节；支持 fixed、revolute、continuous，暂不支持 mimic 或移动关节。
+3. 选择“STL 文件”可一次多选网格。文件名唯一时自动按 URDF 文件名匹配。
+4. 存在同名网格时，改用“资源目录”选择带包路径的根目录；保留 package:// 后的相对目录。
+5. 点击“检查资源”，缺少文件、路径穿越、重名歧义、无效数字或无效关节轴都会阻止导入。
+6. 资源就绪后，按导入零件 → 建立 URDF 层级 → 检查六轴 → 导出执行。
+
+核对：当前工具支持 STL visual；DAE/OBJ、纹理材质、所有 URDF 扩展和碰撞模型不在当前导入范围。
+
+
+## 13 缺少或重名资源的处理
+
+1. 出现“缺少资源”时，按错误中给出的路径找到对应 STL，重新选择完整文件集。
+2. 出现“资源重名”时，不要随意选一个同名文件；改用资源目录，保证路径可以唯一定位。
+3. 文件列表改变后，重新点击“检查资源”。此前的资源就绪状态不再沿用。
+4. 资源检查不会清空当前场景；导入失败也不能替代已有成功结果。
+
+核对：只有资源集明确且完整时，导入按钮才可用。
+
+
+## 14 取消、重复导入与现有对象
+
+1. 原生任务进行时可点击“取消操作”，等待界面解除忙碌状态。
+2. 若任务已进入场景提交阶段，取消可能来不及阻止提交；以界面最终状态和场景为准。
+3. 项目已有工具机器人时，再次导入会拒绝。需要继续工作应点击“读取项目机器人”，而不是重复导入。
+4. 在已有普通工程内导入会保留原对象和资源，但要求机器人对象名称不冲突。
+5. “导出机器人 GLB”只输出机器人；“保存机器人项目”保存整个当前项目。
+
+核对：失败、取消或重复导入不会悄悄替换已有机器人。
+
+
+## 15 小屏与键盘操作
+
+1. 窄屏时工具占据屏幕主要区域，可滚动查看后续分段。
+2. Tab/Shift+Tab 在工具中移动焦点；Escape 在非忙碌状态关闭工具。
+3. 原生操作执行期间关闭按钮禁用；需要终止时使用“取消操作”。
+4. 本轮在 390×844 尺寸检查了工具布局，不等于全部触控设备和移动浏览器都已验收。
+
+核对：文字、数值框与按钮不重叠，主要操作可以通过键盘访问。

+## 坐标系与默认视角
+
+1. Web 场景数据沿用 Blender 右手坐标系：X 为红色，Y 为绿色，Z 为蓝色，Z 轴向上。
+2. Three.js 显示内部采用 Y-up，使用 (x,z,-y) 作显示坐标转换；不改变 Blender 工程或机器人 URDF 的坐标定义。
+3. 右上角轴按钮随观察方向变化。正对视线时，背后的重叠轴按钮不显示；点击当前轴可翻转到相反方向。
+4. 左上角显示当前视图名称及透视/正交状态。物体中心的变换工具与右上角视图轴是不同控件。
+
+## 旋转观察方向
+
+1. 把鼠标移动到三维画布，按住鼠标中键拖动。
+2. 水平方向拖动绕场景上轴旋转，竖直方向拖动改变仰俯角。松开中键结束。
+3. 左键保留选择或编辑用途，不再用左键拖动旋转视角。
+4. 在标准正交视图开始旋转时切回用户透视视图。此行为对应桌面常见的自动透视设置。
+
+## 平移观察区域
+
+1. 在画布上按住 Shift，再按住鼠标中键拖动。
+2. 模型随鼠标在屏幕方向移动，观察中心随之变化，观察距离保持不变。
+3. 平移的是视图，不是机器人、对象或关节位置，不应出现新的几何编辑修订。
+4. 后续编辑或选择对象时不会把平移中心自动重置回原点。
+
+## 放大与缩小
+
+1. 在画布上向前滚动滚轮放大，向后滚动缩小。
+2. 也可使用 Ctrl+中键上下拖动连续缩放，或点击右侧 + / − 按钮。
+3. 小键盘 + / − 也可缩放，快捷键作用于鼠标所在或获得焦点的三维画布。
+4. 透视模式改变观察距离；正交模式改变显示比例。不会缩放模型本身或修改工程单位。
+
+## 前后左右顶底标准视图
+
+1. 小键盘 1：前视图，从 Blender -Y 方向看向场景。
+2. 小键盘 3：右视图，从 +X 方向观察；小键盘 7：顶视图，从 +Z 方向观察。
+3. Ctrl+小键盘 1/3/7 分别切换后、左、底视图。
+4. 标准轴视图使用正交投影。也可点击右上角对应 XYZ 方向；再次点击当前方向会翻转。
+
+## 透视与正交
+
+1. 小键盘 5 或右侧透视/正交图标切换投影。
+2. 正交视图中远近相同尺寸不会因为深度不同而改变画面大小，适合检查轮廓与对齐。
+3. 透视视图保留近大远小。正交缩放后切换透视，尽量保持当前取景比例。
+4. 正交状态下滚轮依然可以放大缩小。
+
+## 显示全部与框显所选
+
+1. Home 或右侧“显示全部”按钮，使当前可见场景进入画面。
+2. 先在 Outliner 或画布选中目标，再按小键盘小数点，或点击“框显所选”。
+3. 选择机器人根节点时会包含其后代可视几何；选择某个零件时围绕该零件取景。
+4. 取景使用原生场景矩阵和几何边界，仅移动观察相机，不修改模型。
+
+## 小屏、焦点和数据保护
+
+1. 窄屏保留视图方向和导航按钮；按钮上悬停可查看名称。
+2. 在输入框、脚本编辑框、下拉框或对话框中输入时，不应触发三维导航快捷键。
+3. 完成旋转、平移和缩放后保存工程，节点、父子关系和对象变换与操作前一致。
+4. 本轮在主线程与 Offscreen、桌面与 390×844 视口执行相同操作并保存截图。

+  <description>
+    <p>
+      ROS-Industrial support for the ABB IRB 120 (and variants).
+    </p>
+    <p>
+      This package contains configuration data, 3D models and launch files
+      for ABB IRB 120 manipulators. This includes the base model (120) and
+      the 120T.
+    </p>
+    <p>
+      Joint limits and max joint velocities are based on the information in the
+      <a href="http://new.abb.com/products/robotics/industrial-robots/irb-120/irb-120-data">
+      ABB IRB 120 technical data sheet</a> (Version: ROB0149EN_D, May 2012).
+      All urdfs / xacros are based on the default motion and joint velocity
+      limits, unless noted otherwise (ie: no support for high speed joints,
+      extended / limited motion ranges or other options).
+    </p>
+    <p>
+      Inertial and mass properties were calculated using 3D modelling software, based on the 
+      supplied <a href="http://new.abb.com/products/robotics/industrial-robots/irb-120/irb-120-cad">
+      ABB IRB 120 CAD model</a>.
+    </p> 
+    <p>
+      Before using any of the configuration files and / or meshes included
+      in this package, be sure to check they are correct for the particular
+      robot model and configuration you intend to use them with.
+    </p>

+A. HISTORY OF THE SOFTWARE
+==========================
+
+Python was created in the early 1990s by Guido van Rossum at Stichting
+Mathematisch Centrum (CWI, see https://www.cwi.nl) in the Netherlands
+as a successor of a language called ABC.  Guido remains Python's
+principal author, although it includes many contributions from others.
+
+In 1995, Guido continued his work on Python at the Corporation for
+National Research Initiatives (CNRI, see https://www.cnri.reston.va.us)
+in Reston, Virginia where he released several versions of the
+software.
+
+In May 2000, Guido and the Python core development team moved to
+BeOpen.com to form the BeOpen PythonLabs team.  In October of the same
+year, the PythonLabs team moved to Digital Creations, which became
+Zope Corporation.  In 2001, the Python Software Foundation (PSF, see
+https://www.python.org/psf/) was formed, a non-profit organization
+created specifically to own Python-related Intellectual Property.
+Zope Corporation was a sponsoring member of the PSF.
+
+All Python releases are Open Source (see https://opensource.org for
+the Open Source Definition).  Historically, most, but not all, Python
+releases have also been GPL-compatible; the table below summarizes
+the various releases.
+

+
+Footnotes:
+
+(1) GPL-compatible doesn't mean that we're distributing Python under
+    the GPL.  All Python licenses, unlike the GPL, let you distribute
+    a modified version without making your changes open source.  The
+    GPL-compatible licenses make it possible to combine Python with
+    other software that is released under the GPL; the others don't.
+
+(2) According to Richard Stallman, 1.6.1 is not GPL-compatible,
+    because its license has a choice of law clause.  According to
+    CNRI, however, Stallman's lawyer has told CNRI's lawyer that 1.6.1
+    is "not incompatible" with the GPL.
+
+Thanks to the many outside volunteers who have worked under Guido's
+direction to make these releases possible.
+
+
+B. TERMS AND CONDITIONS FOR ACCESSING OR OTHERWISE USING PYTHON
+===============================================================
+
+Python software and documentation are licensed under the
+Python Software Foundation License Version 2.
+
+Starting with Python 3.8.6, examples, recipes, and other code in
+the documentation are dual licensed under the PSF License Version 2
+and the Zero-Clause BSD license.
+
+Some software incorporated into Python is under different licenses.
+The licenses are listed with code falling under that license.
+

+(b) under Patent Claims of such Contributor to make, use, sell, offer
+    for sale, have made, import, and otherwise transfer either its
+    Contributions or its Contributor Version.
+
+2.2. Effective Date
+
+The licenses granted in Section 2.1 with respect to any Contribution
+become effective for each Contribution on the date the Contributor first
+distributes such Contribution.
+
+2.3. Limitations on Grant Scope
+
+The licenses granted in this Section 2 are the only rights granted under
+this License. No additional rights or licenses will be implied from the
+distribution or licensing of Covered Software under this License.
+Notwithstanding Section 2.1(b) above, no patent license is granted by a
+Contributor:
+
+(a) for any code that a Contributor has removed from Covered Software;
+    or
+
+(b) for infringements caused by: (i) Your and any other third party's
+    modifications of Covered Software, or (ii) the combination of its
+    Contributions with other software (except as part of its Contributor
+    Version); or
+
+(c) under Patent Claims infringed by Covered Software in the absence of
+    its Contributions.
+
+This License does not grant any rights in the trademarks, service marks,
+or logos of any Contributor (except as may be necessary to comply with
+the notice requirements in Section 3.4).
+
+2.4. Subsequent Licenses
+
+No Contributor makes additional grants as a result of Your choice to
+distribute the Covered Software under a subsequent version of this
+License (see Section 10.2) or under the terms of a Secondary License (if
+permitted under the terms of Section 3.3).
+
+2.5. Representation
+
+Each Contributor represents that the Contributor believes its
+Contributions are its original creation(s) or it has sufficient rights
+to grant the rights to its Contributions conveyed by this License.
+
+2.6. Fair Use
+
+This License is not intended to limit any rights You have under
+applicable copyright doctrines of fair use, fair dealing, or other
+equivalents.
+
+2.7. Conditions
+
+Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses granted
+in Section 2.1.
+
+3. Responsibilities
+-------------------
+
+3.1. Distribution of Source Form
+
+All distribution of Covered Software in Source Code Form, including any
+Modifications that You create or to which You contribute, must be under
+the terms of this License. You must inform recipients that the Source
+Code Form of the Covered Software is governed by the terms of this
+License, and how they can obtain a copy of this License. You may not
+attempt to alter or restrict the recipients' rights in the Source Code
+Form.
+
+3.2. Distribution of Executable Form
+
+If You distribute Covered Software in Executable Form then:
+
+(a) such Covered Software must also be made available in Source Code
+    Form, as described in Section 3.1, and You must inform recipients of
+    the Executable Form how they can obtain a copy of such Source Code
+    Form by reasonable means in a timely manner, at a charge no more
+    than the cost of distribution to the recipient; and
+
+(b) You may distribute such Executable Form under the terms of this
+    License, or sublicense it under different terms, provided that the
+    license for the Executable Form does not attempt to limit or alter
+    the recipients' rights in the Source Code Form under this License.
+
+3.3. Distribution of a Larger Work
+
+You may create and distribute a Larger Work under terms of Your choice,
+provided that You also comply with the requirements of this License for
+the Covered Software. If the Larger Work is a combination of Covered
+Software with a work governed by one or more Secondary Licenses, and the
+Covered Software is not Incompatible With Secondary Licenses, this
+License permits You to additionally distribute such Covered Software
+under the terms of such Secondary License(s), so that the recipient of
+the Larger Work may, at their option, further distribute the Covered
+Software under the terms of either this License or such Secondary
+License(s).
+
+3.4. Notices
+
+You may not remove or alter the substance of any license notices
+(including copyright notices, patent notices, disclaimers of warranty,
+or limitations of liability) contained within the Source Code Form of
+the Covered Software, except that You may alter any license notices to
+the extent required to remedy known factual inaccuracies.
+
+3.5. Application of Additional Terms
+
+You may choose to offer, and to charge a fee for, warranty, support,
+indemnity or liability obligations to one or more recipients of Covered
+Software. However, You may do so only on Your own behalf, and not on
+behalf of any Contributor. You must make it absolutely clear that any
+such warranty, support, indemnity, or liability obligation is offered by
+You alone, and You hereby agree to indemnify every Contributor for any
+liability incurred by such Contributor as a result of warranty, support,
+indemnity or liability terms You offer. You may include additional
+disclaimers of warranty and limitations of liability specific to any
+jurisdiction.
+
+4. Inability to Comply Due to Statute or Regulation
+---------------------------------------------------
+
+If it is impossible for You to comply with any of the terms of this
+License with respect to some or all of the Covered Software due to
+statute, judicial order, or regulation then You must: (a) comply with
+the terms of this License to the maximum extent possible; and (b)
+describe the limitations and the code they affect. Such description must
+be placed in a text file included with all distributions of the Covered
+Software under this License. Except to the extent prohibited by statute
+or regulation, such description must be sufficiently detailed for a
+recipient of ordinary skill to be able to understand it.
+
+5. Termination
+--------------
+
+5.1. The rights granted under this License will terminate automatically
+if You fail to comply with any of its terms. However, if You become
+compliant, then the rights granted under this License from a particular
+Contributor are reinstated (a) provisionally, unless and until such
+Contributor explicitly and finally terminates Your grants, and (b) on an
+ongoing basis, if such Contributor fails to notify You of the
+non-compliance by some reasonable means prior to 60 days after You have
+come back into compliance. Moreover, Your grants from a particular
+Contributor are reinstated on an ongoing basis if such Contributor
+notifies You of the non-compliance by some reasonable means, this is the
+first time You have received notice of non-compliance with this License
+from such Contributor, and You become compliant prior to 30 days after
+Your receipt of the notice.
+
+5.2. If You initiate litigation against any entity by asserting a patent
+infringement claim (excluding declaratory judgment actions,
+counter-claims, and cross-claims) alleging that a Contributor Version
+directly or indirectly infringes any patent, then the rights granted to
+You by any and all Contributors for the Covered Software under Section
+2.1 of this License shall terminate.
+
+5.3. In the event of termination under Sections 5.1 or 5.2 above, all
+end user license agreements (excluding distributors and resellers) which
+have been validly granted by You or Your distributors under this License
+prior to termination shall survive termination.

+*  Covered Software is provided under this License on an "as is"       *
+*  basis, without warranty of any kind, either expressed, implied, or  *
+*  statutory, including, without limitation, warranties that the       *
+*  Covered Software is free of defects, merchantable, fit for a        *
+*  particular purpose or non-infringing. The entire risk as to the     *
+*  quality and performance of the Covered Software is with You.        *
+*  Should any Covered Software prove defective in any respect, You     *
+*  (not any Contributor) assume the cost of any necessary servicing,   *
+*  repair, or correction. This disclaimer of warranty constitutes an   *
+*  essential part of this License. No use of any Covered Software is   *
+*  authorized under this License except under this disclaimer.         *
+*                                                                      *

+*  Under no circumstances and under no legal theory, whether tort      *
+*  (including negligence), contract, or otherwise, shall any           *
+*  Contributor, or anyone who distributes Covered Software as          *

+************************************************************************
+
+8. Litigation
+-------------
+
+Any litigation relating to this License may be brought only in the
+courts of a jurisdiction where the defendant maintains its principal
+place of business and such litigation shall be governed by laws of that
+jurisdiction, without reference to its conflict-of-law provisions.
+Nothing in this Section shall prevent a party's ability to bring
+cross-claims or counter-claims.
+
+9. Miscellaneous
+----------------
+
+This License represents the complete agreement concerning the subject
+matter hereof. If any provision of this License is held to be
+unenforceable, such provision shall be reformed only to the extent
+necessary to make it enforceable. Any law or regulation which provides
+that the language of a contract shall be construed against the drafter
+shall not be used to construe this License against a Contributor.
+
+10. Versions of the License
+---------------------------
+
+10.1. New Versions
+
+Mozilla Foundation is the license steward. Except as provided in Section
+10.3, no one other than the license steward has the right to modify or
+publish new versions of this License. Each version will be given a
+distinguishing version number.
+
+10.2. Effect of New Versions
+
+You may distribute the Covered Software under the terms of the version
+of the License under which You originally received the Covered Software,
+or under the terms of any subsequent version published by the license
+steward.
+
+10.3. Modified Versions
+
+If you create software not governed by this License, and you want to
+create a new license for such software, you may create and use a
+modified version of this License if you rename the license and remove
+any references to the name of the license steward (except to note that
+such modified license differs from this License).
+
+10.4. Distributing Source Code Form that is Incompatible With Secondary
+Licenses
+
+If You choose to distribute Source Code Form that is Incompatible With
+Secondary Licenses under the terms of this version of the License, the
+notice described in Exhibit B of this License must be attached.

+    <p>保存桌面文件夹前，请在 Blender 中将当前 .blend 保存到 /browser/，并等待保存、导出或烘焙完成。保存文件夹会将 /browser/ 内的文件和相对目录写入所选位置下的新文件夹；传输期间请勿修改这些文件。未保存的编辑和 /browser/ 外的资源不包含在内。</p>
+    <p>恢复时选择此前生成的 blender-… 文件夹，其内容会放回 /browser/，然后通过 File → Open 打开其中的 .blend。已有同名文件不会被覆盖；请先通过原生文件浏览器重命名或删除冲突文件。每批最多 2048 个文件，单个文件最多 256 MiB。</p>
+    <p>恢复外部自动保存文件时，先上传 .blend 和所需依赖，再从原生 File → Recover → Auto Save 进入恢复窗口；按 Ctrl+L 可定位到 /browser/ 中对应目录。该流程调用 Blender 的原生文件恢复，区别于浏览器检查点。</p>
+    <p>恢复默认关闭自动执行脚本。确需恢复可信工程的注册脚本或脚本驱动时，在原生文件选择器的操作选项中勾选 Trusted Source，再确认恢复；取消选择器不会执行该文件的脚本。此选项交由 Blender 原生恢复流程处理。</p>
+    <p>“恢复上一次会话”读取原生临时目录中的 quit.blend，默认路径为 /browser/.autosave/quit.blend。请使用“退出并保存会话”或原生 File → Quit，并等到“会话已保存并退出”提示后再关闭页面；直接关闭标签页或浏览器进程可能中断异步写入。退出保存失败时可保留当前会话、备份文件或重试；文件缺失时恢复入口显示 Blender 的原生错误。</p>
+    <p>/browser/ 文件在上传或原生操作完成后同步到本浏览器存储，重新打开页面时恢复；默认原生自动保存目录为 /browser/.autosave/。同一站点只允许一个原生编辑窗口写入。若同步失败，请先下载备份再关闭页面；清除浏览器数据会删除这些文件，建议定期保存桌面文件夹。</p>
+    <p>上传 OBJ、PLY、STL 或 FBX 文件后，在 Blender 的 File → Import 中选择对应格式，在文件浏览器中打开 /browser/。OBJ 的 MTL、OBJ/FBX 的贴图可一并上传；上传文件夹可保留贴图的相对路径。OBJ、PLY 和 STL 可在 File → Export 中导出到 /browser/，然后刷新并下载生成的文件。</p>
+    <p>WAV、MP3、AAC、AC3、MP2、Matroska、FLAC 或 Ogg 音频上传后，在视频序列编辑器中选择 Add → Sound，打开 /browser/ 下的文件。通过顶部 Render → Render Audio 将场景音频保存为 /browser/ 下的 WAV、MP3、AAC、AC3、MP2、Matroska、FLAC 或 Ogg 文件（Vorbis / Opus / FLAC），再刷新并下载；分离声道时可逐个下载生成的文件。MP3 支持单声道、立体声或分离声道输出；常用的 32000、44100、48000 Hz 可使用 32–320 kbit/s 的标准固定码率，较低采样率需降低码率。Opus 支持 8000、12000、16000、24000、48000 Hz；Vorbis 的 Bitrate 设置目标平均码率，实际文件大小随内容而变。Matroska 可选择音频编码器；AAC、AC3 和 MP2 使用各自对应的编码器。码率按每个输出文件计算；如果编码器不接受所选组合，请调整码率、采样率或声道数。</p>
