															+      <p><strong>摘要速读：</strong>Vision-Language-Action (VLA) models for autonomous driving increasingly adopt generative planners trained with imitation learning followed by reinforcement learning. Diffusion-based planners suffer from modality alignment difficulties, low training efficiency, and limited generalization. Token-based planners are plagued by cumulative causal errors and irreversible decoding. In summary, the two dominant paradigms exhibit complementary strengths and weaknesses. In this paper, we propose DriveFine, a masked diffusion VLA model that combines flexible decoding with self-correction capabilities. In particular, we design a novel plug-and-play block-MoE, which seamlessly injects a refinement expert on top of the generation expert. By enabling explicit expert selection during inference and gradient...</p>

															+      <p><strong>摘要速读：</strong>Normalization and scaling are fundamental preprocessing steps in time series modeling, yet their role in Transformer-based models remains underexplored from a theoretical perspective. In this work, we present the first formal analysis of how different normalization strategies, specifically instance-based and global scaling, impact the expressivity of Transformer-based architectures for time series representation learning. We propose a novel expressivity framework tailored to time series, which quantifies a model&#x27;s ability to distinguish between similar and dissimilar inputs in the representation space. Using this framework, we derive theoretical bounds for two widely used normalization methods: Standard and Min-Max scaling. Our analysis reveals that the choice of normalization strategy can...</p>

We present TempoNet, a reinforcement learning scheduler that pairs a permutation-invariant Transformer with a deep Q-approximation. An Urgency Tokenizer discretizes temporal slack into learnable embeddings, stabilizing value learning and capturing deadline proximity. A latency-aware sparse attention stack with blockwise top-k selection and locality-sensitive chunking enables global reasoning over unordered task sets with near-linear scaling and sub-millisecond inference.

Unlike approaches that treat physical grounding as a fine-tuning afterthought, DM0 unifies embodied manipulation and navigation by learning from heterogeneous data sources from the onset. Our methodology follows a comprehensive three-stage pipeline: Pretraining, Mid-Training, and Post-Training. First, we conduct large-scale unified pretraining on the Vision-Language Model (VLM) using diverse corpora--seamlessly integrating web text, autonomous driving scenarios, and embodied interaction logs-to jointly acquire semantic knowledge and physical priors.

However, current AI safety evaluation systems suffer from critical limitations such as restricted risk dimensions and failed frontier risk detection. The lagging safety benchmarks and alignment technologies can hardly address the complex challenges posed by cutting-edge AI models. To bridge this gap, we propose the &quot;ForesightSafety Bench&quot; AI Safety Evaluation Framework, beginning with 7 major Fundamental Safety pillars and progressively extends to advanced Embodied AI Safety, AI4Science Safety, Social and Environmental AI risks, Catastrophic and Existential Risks, as well as 8 crit...</p>

															+## Behavior
														
 
															+
														
 
															+- `message:received`
														
 
															+  - Creates (or reuses) one root node for the active conversation.
														
 
															+  - Adds each incoming message as a child node.
														
 
															+- `agent:bootstrap`
														
 
															+  - Fallback path for direct `openclaw agent ...` turns.
														
 
															+  - Scans recent user messages in the session transcript and appends all unseen turns.
														
 
															+- `message:sent`
														
 
															+  - Runs a post-response reconciliation pass for channels where direct incoming hooks are not emitted.
														
 
															+  - Resolves session id from `sessions.json` when needed, then backfills unseen user turns from transcript.
														
 
															+- `command:new` and `command:reset`
														
 
															+  - Closes the current root node as completed.
														
 
															+  - Next message starts a new root node.
														
 
															+- `command:stop`
														
 
															+  - End-of-turn reconciliation for CLI-style runs.
														
 
															+  - Backfills unseen user messages from transcript so the latest turn is not delayed.

															+# OpenClaw 任务看板：当前实现方法与技术要点（基线）
														
 
															+
														
 
															+更新时间：2026-02-24
														
 
															+
														
 
															+## 1. 当前实现目标与范围
														
 
															+
														
 
															+当前版本已经实现一个可运行的“对话任务看板”基线，核心目标是：
														
 
															+
														
 
															+1. 把 OpenClaw 对话自动同步为任务节点。
														
 
															+2. 以思维导图形式在画布展示父子层级关系。
														
 
															+3. 支持节点详情卡编辑（开始时间、计划、Bug 原因、备注等）。
														
 
															+4. 支持导出 JSON / SVG。
														
 
															+5. 用低饱和粉色主题展示状态，执行中节点带旋转虚线动画。
														
 
															+
														
 
															+## 2. 代码结构与职责
														
 
															+
														
 
															+| 路径 | 职责 |
														
 
															+| --- | --- |
														
 
															+| `task-board/server.js` | Node 原生 HTTP 服务，提供静态资源与任务 CRUD API，持久化到 `tasks.json` |
														
 
															+| `task-board/public/index.html` | 页面结构：顶部工具栏、侧边统计、SVG 画布、节点详情弹窗 |
														
 
															+| `task-board/public/app.js` | 前端状态管理、树布局计算、SVG 绘制、节点交互、导出逻辑 |
														
 
															+| `task-board/public/styles.css` | 低饱和粉色主题、状态色、连线样式、执行中虚线旋转动画、响应式布局 |
														
 
															+| `hooks/task-board-realtime/HOOK.md` | Hook 元数据，声明监听的 OpenClaw 事件 |
														
 
															+| `hooks/task-board-realtime/handler.js` | 对话到任务节点的实时同步逻辑（含去重、补偿扫描、会话收尾） |
														
 
															+| `task-board/.sync-state.json` | Hook 同步状态（会话映射、计数器、已处理消息索引） |
														
 
															+| `task-board/tasks.json` | 看板任务数据文件 |
														
 
															+
														
 
															+## 3. 后端实现（任务服务）
														
 
															+
														
 
															+服务：`task-board/server.js`
														
 
															+
														
 
															+### 3.1 技术选型
														
 
															+
														
 
															+1. Node.js 原生 `http` + `fs`，无额外框架。
														
 
															+2. 单文件 JSON 持久化，适合本地轻量部署与调试。
														
 
															+
														
 
															+### 3.2 任务数据模型
														
 
															+
														
 
															+字段（标准化后）：
														
 
															+
														
 
															+1. `id`：`timestamp-random` 形式字符串。
														
 
															+2. `name`：节点名称，最长 120。
														
 
															+3. `parentId`：父节点 id，根节点为 `null`。
														
 
															+4. `status`：`pending | in-progress | completed | bug`。
														
 
															+5. `createdAt` / `updatedAt`：ISO 时间。
														
 
															+6. `startTime` / `endTime`：可选 ISO 时间。
														
 
															+7. `plannedApproach`：计划说明（最多 2000）。
														
 
															+8. `bugDetails`：Bug 终止说明（最多 2000）。
														
 
															+9. `notes`：补充信息（最多 3000）。
														
 
															+
														
 
															+### 3.3 API
														
 
															+
														
 
															+1. `GET /api/tasks`：返回任务列表。
														
 
															+2. `POST /api/tasks`：创建任务（校验父节点存在）。
														
 
															+3. `PUT /api/tasks/:id`：更新任务（校验状态、时间、父子环）。
														
 
															+4. `DELETE /api/tasks/:id`：级联删除该节点及全子树。
														
 
															+
														
 
															+### 3.4 关键约束
														
 
															+
														
 
															+1. 父子关系禁止成环（`detectCycle`）。
														
 
															+2. 状态自动补齐时间：
														
 
															+3. `in-progress` 无 `startTime` 时自动填充。
														
 
															+4. `completed/bug` 无 `endTime` 时自动填充。
														
 
															+
														
 
															+## 4. 前端实现（画布 + 卡片）
														
 
															+
														
 
															+入口：`task-board/public/app.js`
														
 
															+
														
 
															+### 4.1 画布与布局
														
 
															+
														
 
															+1. 使用 SVG 分层渲染：`linksLayer`（连线）+ `nodesLayer`（节点）。
														
 
															+2. 通过 `buildTreeLayout` 把数据组织成树：
														
 
															+3. 根节点按 `createdAt` 排序。
														
 
															+4. 子节点按 `createdAt` 排序。
														
 
															+5. `x` 由深度决定，`y` 通过 DFS 叶子递增并把父节点放在子树中线。
														
 
															+6. 连线使用三次贝塞尔曲线。
														
 
															+
														
 
															+### 4.2 交互能力
														
 
															+
														
 
															+1. 拖拽平移画布（pointer）。
														
 
															+2. 滚轮缩放（scale clamp）。
														
 
															+3. `fitView` 自动适配到当前节点包围盒。
														
 
															+4. 点击节点打开详情弹窗。
														
 
															+5. 弹窗可编辑状态、时间、计划、Bug、备注；可增删子节点。
														
 
															+6. 导出 JSON 与 SVG。
														
 
															+
														
 
															+### 4.3 状态与视觉表达
														
 
															+
														
 
															+1. 低饱和粉色主色系在 `styles.css` 的 `:root` 变量定义。
														
 
															+2. 状态色：
														
 
															+3. `pending` 灰粉、`in-progress` 粉、`completed` 绿、`bug` 红粉。
														
 
															+4. 执行中动画：
														
 
															+5. 节点外环 `progress-ring` 使用 `stroke-dasharray` + `stroke-dashoffset` 动画旋转虚线。
														
 
															+
														
 
															+## 5. 实时同步实现（OpenClaw Hook）
														
 
															+
														
 
															+入口：`hooks/task-board-realtime/handler.js`
														
 
															+
														
 
															+### 5.1 监听事件
														
 
															+
														
 
															+`HOOK.md` 当前声明：
														
 
															+
														
 
															+1. `message:received`
														
 
															+2. `message:sent`
														
 
															+3. `agent:bootstrap`
														
 
															+4. `command:new`
														
 
															+5. `command:reset`
														
 
															+6. `command:stop`
														
 
															+
														
 
															+### 5.2 同步策略
														
 
															+
														
 
															+1. 对每个 `sessionKey` 维护一个根节点（Conversation）。
														
 
															+2. 每条用户消息写为子节点（Turn）。
														
 
															+3. `/new` 和 `/reset` 时把当前会话根节点置为 `completed`，下次消息再开新根。
														
 
															+4. 如果事件中无 `sessionId`，会从 `~/.openclaw/agents/<agent>/sessions/sessions.json` 反查。
														
 
															+5. transcript 读取策略：
														
 
															+6. 在 `sessionId.jsonl` 与 `sessionId-topic-*.jsonl` 中选择最近修改的文件。
														
 
															+7. 扫描尾部用户消息并批量补写未处理消息。
														
 
															+
														
 
															+### 5.3 去重与状态文件
														
 
															+
														
 
															+1. 去重键：`sessionKey::messageId`，无 messageId 时使用内容+时间 hash。
														
 
															+2. `task-board/.sync-state.json` 保存：
														
 
															+3. `sessions`：会话到根节点映射。
														
 
															+4. `counters`：会话根节点编号计数。
														
 
															+5. `messages`：已处理消息索引（防重复写入）。
														
 
															+6. 配置项：
														
 
															+7. `maxRememberedMessages` 控制消息去重索引上限。
														
 
															+
														
 
															+### 5.4 时序补偿（避免“慢一拍”）
														
 
															+
														
 
															+1. 事件触发时先进行一次即时 transcript 扫描。
														
 
															+2. 额外安排异步延迟补扫（当前为 1600ms、4800ms），不阻塞主流程。
														
 
															+3. 该机制用于处理 transcript 落盘晚于 hook 触发时刻的情况。
														
 
															+
														
 
															+## 6. 当前实现与需求对照
														
 
															+
														
 
															+### 6.1 已满足
														
 
															+
														
 
															+1. 对话自动入板（主节点 + 子节点）。
														
 
															+2. 层级关系可视化。
														
 
															+3. 状态色区分明确。
														
 
															+4. 执行中旋转虚线动画。
														
 
															+5. 节点详情卡字段完整。
														
 
															+6. 导出 JSON / SVG。
														
 
															+7. 低饱和粉色整体风格。
														
 
															+
														
 
															+### 6.2 当前缺口（你刚提出的两点）
														
 
															+
														
 
															+1. 缺少“按对话筛选”的下拉标签或会话选择器。
														
 
															+2. 当前布局是“树状层级布局”，不是“思考链/思维链”导图语义布局。
														
 
															+
														
 
															+## 7. 已知技术限制与结构问题
														
 
															+
														
 
															+1. 数据层是平铺数组 + `parentId`，缺少对“对话维度”的一级索引接口。
														
 
															+2. 前端默认一次渲染全部节点，缺少“按会话聚焦/隔离”。
														
 
															+3. 节点语义目前只有根/子区分，缺少“推理步骤类型”（观察、假设、行动、验证、结论等）建模。
														
 
															+4. 布局算法是静态树排布，不包含链路方向强化、时间轴、分支合并等“思考链视觉语法”。
														
 
															+5. 同步依赖本地 JSON 文件，暂不支持多实例并发写入。
														
 
															+
														
 
															+## 8. 后续重构建议（用于你准备的新结构）
														
 
															+
														
 
															+1. 数据层先引入“会话视图模型”：
														
 
															+2. `conversationId -> nodes[]` 与全量任务存储分离。
														
 
															+3. API 增加 `GET /api/conversations` 与 `GET /api/tasks?conversationId=...`。
														
 
															+4. 前端增加“会话下拉 + 标签筛选 + 仅看当前会话”模式。
														
 
															+5. 把当前树布局抽象成 `layout engines`：
														
 
															+6. `tree`（兼容模式）+ `thought-chain`（新模式）可切换。
														
 
															+7. 给节点补充“思考链语义字段”（例如 `stepType`, `confidence`, `evidenceRef`）。
														
 
															+8. Hook 写入时可按语义模板自动填充（至少先区分 user-turn / agent-turn / tool-turn）。
														
 
															+
														
 
															+---
														
 
															+
														
 
															+如果后续要拆目录，建议以 `backend/`, `frontend/`, `sync-hook/`, `docs/` 四层分离，先保证 API 与布局引擎可独立迭代。

															+# OpenClaw 任务看板 V2：系统架构与开发规范

														
 
															+

														
 
															+**版本**: 2.0 (包含 V2.1 诊断特性与 V2.2 上下文压缩算法)

														
 
															+**核心定位**: 面向公网的高安全只读看板 + 大模型思维链 (CoT) 可视化引擎 + 基于图遍历的动态上下文管理器。

														
 
															+

														
 
															+## 1. 架构设计哲学 (Design Philosophy)

														
 
															+

														
 
															+1. **零信任读写分离 (Zero-Trust Read/Write Split)**：暴露在公网的服务仅提供纯静态渲染与只读 API，所有写操作强制通过 Admin API 配合 Bearer Token 鉴权。

														
 
															+2. **拒绝向量化中转 (No RAG/Embedding for State)**：摒弃使用 Embedding 模型作为任务状态缓存的方案。任务的本质是拓扑结构 (Topological Structure)，采用算法层面的**图遍历修剪 (Graph Traversal Pruning)** 实现上下文压缩，保留精确的前置/后置逻辑引用。

														
 
															+3. **白盒化执行 (White-box Execution)**：将本地 Ollama 模型的截断原因、Token 消耗、推理步骤，通过结构化解析实时映射到可视化节点，终结黑盒调试。

														
 
															+

														
 
															+---

														
 
															+

														
 
															+## 2. 系统目录结构与模块划分

														
 
															+

														
 
															+系统严格按职责分为四层微服务架构：

															+### 3.1 增强型节点模型 (Node Schema V2)

														
 
															+

														
 
															+在系统间流转的最小数据单元，扩展了语义类型与大模型诊断信息。

															+` ` `json

															+  }

														
 
															+}

														
 
															+` ` `

														
 
															+

														
 
															+---

														
 
															+

														
 
															+## 4. 核心子系统规范

														
 
															+

														
 
															+### 4.1 通信与安全总线 (Backend)

														
 
															+* **Public API**: `GET /api/public/conversations` 与 `GET /api/public/tasks/:conversationId`。仅响应 JSON，无鉴权，但需配置 CORS 与限流。

														
 
															+* **Admin API**: `POST/PUT/DELETE /api/admin/tasks`。用于 `sync-hook` 推送节点变更，Header 必须校验 `Authorization: Bearer <TOKEN>`。

														
 
															+* **SSE 流**: `GET /api/public/stream/:conversationId`。建立单向长连接，当 Admin API 触发数据变更时，向对应会话的订阅者广播增量 JSON。

														
 
															+

														
 
															+### 4.2 思维导图渲染引擎 (Frontend)

														
 
															+* **布局算法 (Layout Engine)**: 废弃传统静态树。基于水平主轴 (时间线) 与垂直发散 (任务拆解) 计算 SVG 坐标。支持多节点收敛到单一 `conclusion` 节点 (DAG 渲染)。

														
 
															+* **视觉语言**:

														
 
															+  * `in-progress`: 保留旋转虚线，叠加脉冲发光 (`feGaussianBlur`)。

														
 
															+  * `bug` (如 `stopReason === 'length'`): 节点外发红光，并在 UI 提供 Debug 详情面板。

														
 
															+

														
 
															+### 4.3 上下文管理与注入引擎 (State Injection)

														
 
															+严格控制传递给大模型的上下文长度，限制条件为：

														
 
															+$N_{total}=N_{prompt}+N_{predict}\le N_{ctx}$

														
 
															+

														
 
															+利用 `tree-pruner.js` 实现基于当前焦点节点的 $O(N)$ 复杂度修剪算法：

														
 
															+1. **保留寻址坐标**: 完整输出从根节点到焦点节点的祖先路径。

														
 
															+2. **暴露局部视野**: 完整输出焦点节点的直接子节点。

														
 
															+3. **模糊兄弟分支**: 兄弟节点仅保留 `[状态] 标题`。

														
 
															+4. **折叠远端历史**: 已完成的无关树分支整合成一行统计摘要。

														
 
															+

														
 
															+**输出形式**: 精简版 Markdown 文本，由 `sync-hook` 在每次请求前动态拉取，并作为 `System Prompt` 注入。

														
 
															+

														
 
															+### 4.4 大模型能力扩展 (Agent Tools)

														
 
															+为应对修剪算法可能导致的深层历史细节丢失，必须向 Ollama 注册 Function Calling：

														
 
															+* **Tool Name**: `get_task_details`

														
 
															+* **Input**: `taskId`

														
 
															+* **Execution**: Hook 拦截该调用，请求 `backend` 获取该节点的完整 JSON（含 `notes`, `bugDetails`），作为 `observation` 节点返回给大模型。

														
 
															+

														
 
															+---

														
 
															+

														
 
															+## 5. 阶段性开发路线 (Implementation Roadmap)

														
 
															+

														
 
															+1. **Phase 1: 基础设施重构 (Backend & Data Layer)**

														
 
															+   * 初始化分离的目录结构。

														
 
															+   * 实现只读 Public API、鉴权 Admin API 与 JSON 持久化。

														
 
															+   * 实现跨端 SSE 推送服务。

														
 
															+2. **Phase 2: 核心算法与大模型对接 (Context & Hooks)**

														
 
															+   * 编写 `tree-pruner.js` 实现焦点树修剪算法。

														
 
															+   * 在 `sync-hook` 中实现 XML 标签解析 (`<plan>`, `<think>`, `<action>`)，并将数据映射到 Admin API。

														
 
															+   * 注入 `get_task_details` 工具。

														
 
															+3. **Phase 3: 可视化与交互 (Frontend SVG)**

														
 
															+   * 重写基于 DAG 的水平-垂直布局算法。

														
 
															+   * 接入 SSE 流实现页面无刷新的节点状态闪烁与连线绘制。

														
 
															+   * 开发包含 `llmDiagnostics` 数据的调试侧边栏。

														
 
															+
