 - [x] 在 activity layer 之后继续补 `route leak` 和 `path instability / flap` detector
 - [ ] 对 [frontend/public/earth/js/bgp.js](/home/ray/dev/linkong/planet/frontend/public/earth/js/bgp.js) 做按职责拆分的小重构，拆成 data / markers / overlays / animation，降低后续维护复杂度
 - [ ] 可选优化（非必做）：将 BGP incident/collector 标点改为 HTML marker（参考 worldmonitor 的 `htmlElementsData` 思路），实现近乎固定屏幕尺寸与更高密度可点击性
+- [ ] 保持 Earth 当前这批纯个人偏好设置继续走本地持久化：`旋转模式`、HUD 面板显示/隐藏、`地形透明度` 暂不升级到后端系统设置，避免把设备级偏好过早做成全局配置
+- [ ] 如果后续明确需要“账号级同步 Earth 偏好”，再单独设计 `Earth user preferences`：优先按用户维度而不是全局系统设置保存，并规划 `localStorage -> backend` 的平滑迁移策略
+- [ ] 把 Earth 态势新闻源从 [earth_news.py](/home/ray/dev/linkong/planet/backend/app/services/earth_news.py) 的硬编码列表抽成可配置目录，优先保持当前“实时聚合”链路不变，只先解决新闻源不可配置的问题
+- [ ] 为 Earth 态势新闻设计后续采集器化方案：明确新闻数据模型、去重策略、区域映射、过期清理和 Earth/AI 复用方式，再决定何时把新闻从实时抓取升级成正式 collector

+# Earth News Source Configuration And Collector Plan
+
+## Why
+
+当前 Earth 的“态势新闻”由 [earth_news.py](/home/ray/dev/linkong/planet/backend/app/services/earth_news.py) 直接在请求时抓取 RSS / Google News feed，再按当前地球视角中心区域聚合返回。
+
+这条链已经可用，但存在两个明显限制：
+
+- 新闻源写死在代码里，不能像 TV 直播源一样从后台维护
+- 新闻并未进入统一采集体系，没有采集状态、失败监控、历史数据和后续 AI 复用能力
+
+因此这块更合理的路线不是一步到位重写，而是分阶段推进：
+
+1. 先做“新闻源配置化”
+2. 再做“新闻采集器化”
+
+## Current State
+
+当前实现分布在：
+
+- 新闻接口
+  - [news.py](/home/ray/dev/linkong/planet/backend/app/api/v1/news.py)
+- 实时聚合逻辑
+  - [earth_news.py](/home/ray/dev/linkong/planet/backend/app/services/earth_news.py)
+- 前端消费
+  - [news.js](/home/ray/dev/linkong/planet/frontend/public/earth/js/news.js)
+
+当前新闻源包含：
+
+- `BBC World` RSS
+- `DW Top Stories` RSS
+- 按区域关键词拼出来的 `Google News RSS`
+  - `Global`
+  - `Americas`
+  - `Europe`
+  - `Middle East / Africa`
+  - `Asia Pacific`
+
+当前不是采集器，也不落库，只做内存缓存。
+
+## Phase 1: Source Configuration
+
+### Goal
+
+把 `NEWS_FEED_SOURCES` 从硬编码列表升级成可配置新闻源目录，但继续保留当前“实时聚合”的工作方式。
+
+### Scope
+
+- 为 Earth news 建立独立配置结构
+- 支持后台维护 feed 源
+- 支持启用/禁用、优先级、区域、源类型
+- 保持现有 `/api/v1/news/earth-feed` 输出协议不变
+
+### Proposed Shape
+
+建议配置字段至少包括：
+
+- `id`
+- `name`
+- `region`
+- `feed_url`
+- `homepage_url`
+- `source_type`
+- `priority`
+- `is_enabled`
+- 可选 `query_profile`
+- 可选 `language`
+- 可选 `notes`
+
+### Suggested Storage
+
+优先走系统设置或单独的 news source settings payload，而不是先建复杂新表。
+
+推荐原因：
+
+- 改动小
+- 易上线
+- 和当前 TV settings 维护体验更接近
+- 先解决“写死在代码里”的问题
+
+### Non-goals
+
+这一阶段不做：
+
+- 新闻入库
+- 新闻历史回看
+- 新闻采集任务监控
+- 新闻去重流水线
+
+## Phase 2: News Collectorization
+
+### Goal
+
+把“态势新闻”升级为真正的采集器链路，使其进入采集系统和数据层。
+
+### Scope
+
+- 新增专用 news collector
+- 按配置源定时采集 RSS / feed
+- 做标题/链接级去重
+- 建立统一新闻记录模型
+- 为 Earth、控制台、AI 研判复用同一份新闻数据
+
+### Benefits
+
+- 有采集状态
+- 有失败监控
+- 有历史缓存
+- 可以做时间轴 / 区域新闻基线
+- 可以作为 AI 引用证据
+
+### Required Design Work
+
+需要提前明确：
+
+- 新闻数据模型
+- 去重策略
+- 过期清理策略
+- 区域映射策略
+- 聚合排序策略
+- 新闻与 Earth 当前视角/区域的关联方式
+
+### Candidate Output Model
+
+至少应包含：
+
+- `source_id`
+- `headline`
+- `summary`
+- `url`
+- `publisher`
+- `region`
+- `published_at`
+- `language`
+- `tags`
+- `raw_feed_source`
+- `reference_date`
+
+## Recommended Order
+
+推荐执行顺序：
+
+1. 先完成 Phase 1 配置化
+2. 保持 Earth 继续实时聚合，但改为读取配置源
+3. 等新闻源稳定后，再设计 Phase 2 的 collector / storage / dedupe
+
+## Decision
+
+当前结论：
+
+- TV 直播源：优先采集器化
+- 态势新闻：优先配置化，再采集器化
+
+## Source Note
+
+This plan is newly created for the Planet repo to separate the short-term "configurable source directory" work from the longer-term "collectorized news pipeline" work.

+# Earth Predicted Orbit Plan
+
+> Source note: this plan absorbs useful ideas from a sisyphus-created draft formerly stored at `.sisyphus/plans/predicted-orbit.md`.
+
+## Goal
+
+在 Earth 中锁定卫星时，显示“预测轨道”而不是只有历史尾迹：
+
+- 从当前时刻开始
+- 绕地球一圈
+- 当前点最亮
+- 向后沿轨道逐步衰减
+
+## Current State
+
+当前已经有：
+
+- 卫星历史轨迹
+- 锁定卫星
+- 轨道高亮与相关联动
+
+但“预测轨道”仍然不是一套稳定、可验证的单独功能计划。
+
+## Why It Is Valuable
+
+预测轨道可以明显提升：
+
+- 锁定卫星后的空间可读性
+- 轨道类型辨识
+- 演示解释力
+
+相比短历史尾迹，预测轨道更符合用户对“这颗卫星接下来会怎么走”的预期。
+
+## Scope
+
+### Phase 1
+
+- 锁定卫星时显示一整圈预测轨道
+- 解锁时隐藏
+- 不替代现有普通轨迹系统
+
+### Phase 2
+
+- 根据轨道类型调整采样率
+- GEO / MEO / LEO 不同密度
+- 进一步减少 fallback 轨迹的比例
+
+## Implementation Direction
+
+### 1. Orbit period
+
+基于 `meanMotion` 估算轨道周期。
+
+### 2. Predicted samples
+
+以固定采样步长从 `now -> now + period` 推算轨迹点。
+
+### 3. Render object lifecycle
+
+预测轨道应是一个独立渲染对象：
+
+- show
+- update
+- hide
+- dispose
+
+### 4. Visual semantics
+
+预测轨道不应与普通尾迹混淆：
+
+- 更稳定
+- 更完整
+- 透明度沿轨道衰减
+- 当前点附近更亮
+
+## Known Risks
+
+### 1. TLE propagation gaps
+
+部分卫星可能出现 SGP4 计算不足，需要 fallback。
+
+### 2. Multiple orbit lines
+
+必须确保：
+
+- 锁定切换前先清旧轨道
+- 页面隐藏/销毁时清理
+
+### 3. Performance
+
+GEO 轨道点数高，采样率需要按轨道类型分层。
+
+## Acceptance
+
+1. 锁定单颗卫星时只显示一条预测轨道
+2. 解锁后轨道立即清除
+3. 不同轨道类型下点数可控
+4. 页面切换回来不会闪出旧轨道残留

+# Earth Renderer / Logic Separation Plan
+
+> Source note: this plan absorbs useful ideas from a sisyphus-created draft formerly stored at `.sisyphus/plans/earth-architecture-refactor.md`.
+
+## Goal
+
+将 Earth 前端继续往“逻辑层 / 状态层 / 渲染层”分离推进，降低后续这几类工作的耦合成本：
+
+- Three.js 渲染重构
+- 部分图层替换实现
+- 未来 UE / Cesium 客户端迁移
+- Earth 行为逻辑复用
+
+## Why This Matters
+
+当前 Earth 已经有一些良好分层，例如：
+
+- 图层显隐入口
+- Cable state 枚举与状态 map
+- 交互逻辑与实际视觉效果的部分分离
+
+但还没有形成一套更明确的统一规则。现在的风险是：
+
+- 同一类对象的 hover / locked / hidden / loading 语义不一致
+- 状态和渲染更新散落在多个模块
+- 后续再加新图层时容易复制旧逻辑
+
+## Target Architecture
+
+Earth 对每类对象都尽量拆成三层：
+
+1. `state layer`
+   - 保存对象状态
+   - 例如：`normal / hovered / locked / hidden / loading`
+
+2. `logic layer`
+   - 处理点击、悬停、锁定、过滤、显隐切换
+   - 不直接关心 Three.js 具体材质怎么改
+
+3. `renderer layer`
+   - 根据状态更新 Three.js / HUD 外观
+   - 是最容易针对不同渲染引擎替换的一层
+
+## Current Good Signals
+
+当前已经接近这条方向的地方：
+
+- cable 状态管理
+- 部分 landing point 状态同步
+- layer button 的统一状态入口
+- tooltip / legend / info-card 开始朝状态驱动靠拢
+
+## Next Steps
+
+### 1. Standardize object state enums
+
+优先为这些对象建立更稳定的状态语义：
+
+- cables
+- satellites
+- landing points
+- BGP markers
+- media / news 面板入口按钮
+
+### 2. Unify state-to-visual adapters
+
+为各模块建立更清晰的渲染适配函数，例如：
+
+- `applyCableVisualState()`
+- `applySatelliteVisualState()`
+- `applyBGPVisualState()`
+
+要求：
+
+- 逻辑层只改状态
+- 视觉层负责把状态映射到材质、透明度、发光、尺寸、文字
+
+### 3. Separate Earth UI state from render state
+
+HUD / 面板 / 图层按钮状态也需要和渲染状态分离：
+
+- `loading`
+- `active`
+- `locked`
+- `hidden`
+- `error`
+
+不要再让 UI 通过“猜渲染结果”推导业务状态。
+
+### 4. Prepare migration-safe boundaries
+
+后续如果做 UE / Cesium 客户端，尽量保留：
+
+- 状态枚举
+- 交互规则
+- 数据层接口
+
+只替换：
+
+- Three.js 具体渲染实现
+- HUD 展示实现
+
+## Practical Rule
+
+后续 Earth 新功能开发时，优先问三个问题：
+
+1. 这个状态由谁持有？
+2. 这个交互逻辑在哪一层处理？
+3. 这个视觉变化是否能在不改逻辑的情况下单独替换？
+
+如果答不上来，就说明还在把状态、逻辑、渲染揉在一起。

+# Earth WebGL Instancing Satellites Plan
+
+> Source note: this plan absorbs useful ideas from a sisyphus-created draft formerly stored at `.sisyphus/plans/webgl-instancing-satellites.md`.
+
+## Goal
+
+把 Earth 卫星渲染从当前方案继续推进到更适合高数量卫星的 instancing 方向，目标是：
+
+- 支持更多卫星
+- 降低渲染压力
+- 仍然保留当前数据层和交互层
+
+## Why It Matters
+
+当前卫星系统已经具备：
+
+- 数据加载
+- 轨迹
+- 选择/锁定
+- 图例
+- 相关区域联动
+
+但当卫星数量持续增加时，渲染层会越来越接近瓶颈。
+
+## Recommended Direction
+
+优先调研并原型验证：
+
+- `InstancedBufferGeometry + custom shader`
+
+而不是一开始就推倒重写成 raw WebGL。
+
+原因：
+
+- 仍能保留 Three.js 主架构
+- 更容易渐进迁移
+- 比继续堆普通点渲染更有上限
+
+## What Should Stay
+
+尽量保留这些层：
+
+- 卫星数据获取
+- 位置计算
+- 锁定/悬停逻辑
+- legend / info-card / 相关联动
+
+主要替换的是：
+
+- 卫星点渲染实现
+- 颜色/大小等实例属性更新方式
+
+## Phases
+
+### Phase 1: Prototype
+
+- 用 instancing 做最小原型
+- 先只渲染卫星点
+- 不碰轨迹系统
+
+### Phase 2: Integrate
+
+- 接入当前 `satellites.js` 数据层
+- 保留当前选择和高亮语义
+
+### Phase 3: Tune
+
+- 调整可视大小
+- 调整选中高亮方式
+- 评估是否需要分层 LOD
+
+## Risks
+
+1. 透明度排序更复杂
+2. Shader 调试成本更高
+3. 选中态和 hover 态不能简单复用旧材质逻辑
+
+## Acceptance
+
+1. 在更高卫星数量下保持可接受帧率
+2. 不破坏现有锁定/高亮语义
+3. 图例、信息卡、相关卫星联动仍然成立

+- 让 HUD、图层、媒体面板、BGP、卫星、海缆等保持统一交互
+- 把加载中、已启用、已隐藏、锁定中这类状态做清楚

+Earth 的 CSS 不是一份大样式表，而是分层管理：
+
+- [base.css](/home/ray/dev/linkong/planet/frontend/public/earth/css/base.css)
+- [hud.css](/home/ray/dev/linkong/planet/frontend/public/earth/css/hud.css)
+- [toolbar.css](/home/ray/dev/linkong/planet/frontend/public/earth/css/toolbar.css)
+- [layer-panel.css](/home/ray/dev/linkong/planet/frontend/public/earth/css/layer-panel.css)
+- [info-panel.css](/home/ray/dev/linkong/planet/frontend/public/earth/css/info-panel.css)
+- [legend.css](/home/ray/dev/linkong/planet/frontend/public/earth/css/legend.css)
+- [earth-stats.css](/home/ray/dev/linkong/planet/frontend/public/earth/css/earth-stats.css)
+- [coordinates-display.css](/home/ray/dev/linkong/planet/frontend/public/earth/css/coordinates-display.css)
+- [tv-panel.css](/home/ray/dev/linkong/planet/frontend/public/earth/css/tv-panel.css)
+
+当前建议：
+
+- 通用 HUD 壳层写进 `hud.css`
+- 单一面板特性写进各自子文件
+- 不要把业务状态样式再散回 `index.html`
+
+## 当前图层开关状态语义
+
+Earth 图层按钮现在不应再只有“开/关”两态，而应支持：
+
+- `inactive`
+- `active`
+- `loading`
+
+当前入口在：
+
+- [controls.js](/home/ray/dev/linkong/planet/frontend/public/earth/js/controls.js)
+- [layer-button-state.js](/home/ray/dev/linkong/planet/frontend/public/earth/js/layer-button-state.js)
+
+关键函数：
+
+- `updateLayerButtonState(button, isActive)`
+- `setLayerButtonState(button, options)`
+
+`setLayerButtonState` 负责：
+
+- `loading` 样式
+- `aria-busy`
+- 按钮禁用
+- tooltip 更新
+- 绑定状态文本更新
+- 可选同步 `active`
+
+因此后续如果别的图层也需要异步启用，应该直接走这套状态机，而不是再手写一套临时 loading class。
+
+另外，Earth 图层控制现在已经收成“注册表驱动”：
+
+- 图层元数据
+  - `id`
+  - `icon`
+  - `label`
+  - `meta`
+  - `buttonId`
+  - `persist`
+  - `startupPriority`
+  - `startupMode`
+  - `startupLabel`
+  - `startupMessage`
+- 图层行为
+  - `getVisible()`
+  - `setVisible(next, options)`
+
+当前入口仍在 [controls.js](/home/ray/dev/linkong/planet/frontend/public/earth/js/controls.js)。
+
+这意味着后续新增图层时，优先应补一条图层注册定义，而不是同时去改：
+
+- 图层面板 HTML
+- 持久化快照
+- 初始化恢复
+- click 绑定
+
+这四处现在都应该由注册表派生。
+
+其中：
+
+- `startupPriority`
+  - 描述图层参与启动加载时的顺序
+- `startupMode`
+  - `visible`
+    - 仅当前图层处于启用/可见状态时，才加入启动加载队列
+  - `preload`
+    - 即使当前图层未显示，也会参与启动预加载
+
+当前 `main.js` 会通过注册表读取排序后的启动图层列表，再动态拼装启动加载队列，而不是手写一串固定步骤。像 BGP 这类需要尽早准备数据、但不一定默认显示的图层，应该优先走 `startupMode: "preload"`，而不是在启动流程里写隐式特判。
+
+此外，启动阶段给用户看的提示文案也应尽量从注册表派生：
+
+- `startupLabel`
+  - 用于描述当前启动任务的业务名称
+- `startupMessage`
+  - 用于描述启动中的提示文案
+  - 可以是字符串
+  - 也可以是对象，用于像海缆这种“准备阶段 / 主加载阶段”两段式文案
+
+这样后续新增会参与启动加载的图层时，顺序、模式和提示文案都在同一处定义，不需要再去 `main.js` 里补第二套常量。
+
+### `data-status-target`
+
+图层按钮可以通过：
+
+- `data-status-target`
+
+指向一个状态文本节点。当前 terrain 已接入：
+
+- 按钮：`#toggle-terrain`
+- 状态节点：`#terrain-status`
+
+以后别的异步图层也可以沿用这套约定。
+
+## 当前设置持久化
+
+Earth 设置面板当前由 [controls.js](/home/ray/dev/linkong/planet/frontend/public/earth/js/controls.js) 统一负责：
+
+- 捕获默认值
+- 从 `localStorage` 读取上次设置
+- 初始化应用当前设置
+- 用户变更后即时持久化
+- 一键重置回默认值
+
+当前持久化的范围是：
+
+- 旋转模式
+- 地球默认大小（作为重置视角、缩放重置和巡航视图的默认 zoom 真源）
+- HUD 面板显示/隐藏
+- 图层控制开关：`地形 / 卫星 / 轨迹 / 海缆 / BGP`
+- 地形透明度
+
+也就是说，Earth 设置不是一次性 UI 状态了，而是本地设备级偏好。后续如果再加入新的设置项，应优先接入同一条持久化链，而不是各自散着写 `localStorage`。
+
+## 当前地形链路
+
+真实地形首次启用会慢，原因不只是一个：
+
+1. 需要拉取 Terrarium 瓦片
+2. 需要解码图片
+3. 需要按顶点采样高程
+4. 需要重新写入 geometry 和 color
+5. 需要重新计算法线与包围体
+
+当前入口在：
+
+- [terrain.js](/home/ray/dev/linkong/planet/frontend/public/earth/js/terrain.js)
+
+当前已经做了两层体验优化：
+
+1. 图层开关 loading 状态持续可见
+2. 页面空闲时会预热 `ensureTerrainReady()`
+
+也就是说，后续再继续优化 terrain 时，优先顺序应该是：
+
+1. 先保证用户感知正确
+2. 再压缩首次等待
+3. 最后才做更激进的几何/瓦片优化
+
+## 当前高频风险点
+
+### 1. 视觉状态和业务状态不同步
+
+Earth 里最常见的 bug 不是“没渲染”，而是：
+
+- 图层关了，tooltip 还在
+- 锁定对象隐藏了，info card 还在
+- legend 没跟图层切换
+- loading 已结束，但按钮还像没开
+
+后续改动必须优先检查状态同步。
+
+### 2. HUD 布局问题先查结构，不要先打 CSS 补丁
+
+Earth HUD 历史上反复出现：
+
+- 面板只剩一条缝
+- markdown 被裁掉
+- tabs/iframe 被 `overflow: hidden` 吃掉
+
+优先检查：
+
+1. 谁负责高度
+2. 谁负责滚动
+3. 哪一层在裁剪
+
+不要上来先加 `overflow: hidden` 或额外包装层。
+
+### 3. Transitional path 必须收口
+
+Earth 已经经历过多轮 HUD、toolbar、media panel 重构，所以最容易积累：
+
+- 旧 helper
+- 旧 class
+- 旧 fallback 逻辑
+- 已废弃变体
+
+每次大功能完成后，都要做一次 cleanup pass。
+
+### 4. 巡航与业务事件不要再深度耦合
+
+当前正确边界应该是：
+
+- 通用巡航层只知道：
+  - 当前目标
+  - 队列顺序
+  - 相机 focus
+  - 停留 / 隐藏 / 切换
+- 业务模块只负责：
+  - 提供目标队列
+  - 提供 focus 坐标
+  - 提供卡片内容
+  - 提供高亮/图层副作用
+
+如果以后再给海缆、卫星或新闻做巡航，不应复制一套新的 `main.js` 状态变量，而应复用：
+
+- [cruise-sequencer.js](/home/ray/dev/linkong/planet/frontend/public/earth/js/cruise-sequencer.js)
+- [callout-connector.js](/home/ray/dev/linkong/planet/frontend/public/earth/js/callout-connector.js)
+- [bgp-cruise-adapter.js](/home/ray/dev/linkong/planet/frontend/public/earth/js/bgp-cruise-adapter.js) 这种业务适配层模式
+
+## 当前推荐改动方式
+
+如果后续继续改 Earth，建议按这个顺序：
+
+1. 先确认改的是：
+   - Three.js 渲染层
+   - HUD 结构层
+   - 图层状态层
+   - 面板内容层
+2. 如果涉及图层按钮，优先接入统一状态机
+3. 如果涉及可见性切换，检查 tooltip / legend / info-card / lock 是否一起收口
+4. 如果涉及面板布局，先查结构再动 CSS
+
+## 当前与控制台前端的边界
+
+Earth 前端和控制台前端不是同一套 UI 系统：
+
+- 控制台前端：React + Ant Design 工作台
+- Earth 前端：`public/earth` 原生 HUD + Three.js 展示面
+
+因此：
+
+- Earth 不应该直接复用 Ant Table / AppLayout 语义
+- 控制台也不应该照搬 Earth HUD 动画和玻璃层语言
+
+控制台相关结构见：

+# Admin Frontend Context
+
+本文件描述当前控制台前端的真实结构，目标是帮助后续页面开发、表格改造、布局治理和状态收口时快速找到正确入口。
+
+相关规则建议一起参考：
+
+- [rules.md](/home/ray/dev/linkong/planet/rules.md)
+- [frontend-layout-guidelines.md](/home/ray/dev/linkong/planet/docs/technical/frontend-layout-guidelines.md)
+
+## 当前目标
+
+控制台前端承担的是后台工作台，而不是展示型大屏。当前约束是：
+
+- 页面默认遵循单屏工作区
+- 主交互在内部模块滚动，而不是依赖整页无限变长
+- 列表、表格、分析页优先保证主工作区可见
+- 通用布局、滚动条、表格滚动行为尽量复用，不要每页各写一套
+
+## 当前路由入口
+
+主入口在：
+
+- [App.tsx](/home/ray/dev/linkong/planet/frontend/src/App.tsx)
+
+当前后台相关路由包括：
+
+- `/admin`
+- `/users`
+- `/datasources`
+- `/data`
+- `/alerts/system`
+- `/alerts/bgp`
+- `/alerts/situational`
+- `/bgp`
+- `/playground`
+- `/settings`
+
+`/earth` 是独立展示页，不属于控制台骨架。
+
+## 当前页面骨架
+
+控制台公共壳层在：
+
+- [AppLayout.tsx](/home/ray/dev/linkong/planet/frontend/src/components/AppLayout/AppLayout.tsx)
+
+职责：
+
+- 左侧导航
+- 折叠与展开
+- 当前账号/版本信息
+- 内容区高度闭合
+- 全站统一侧边栏滚动条
+
+当前结构是：
+
+```tsx
+<Layout className="dashboard-layout">
+  <Sider className="dashboard-sider">...</Sider>
+  <Layout>
+    <Content className="dashboard-content">
+      <div className="dashboard-content-inner">{children}</div>
+    </Content>
+  </Layout>
+</Layout>
+```
+
+后续控制台页面应优先适配这套壳层，而不是重新定义全页高度语义。
+
+## 当前共享组件
+
+### 1. `Scrollbar`
+
+文件：
+
+- [Scrollbar.tsx](/home/ray/dev/linkong/planet/frontend/src/components/Scrollbar/Scrollbar.tsx)
+
+用途：
+
+- 控制台侧边栏这类普通内容容器
+- 组件内部管理可见性、thumb 尺寸、拖拽和双轴 overflow 判定
+
+当前约束：
+
+- 滚动条必须是浮层，不参与布局
+- 无 overflow 时不应留下可见痕迹
+- 真实滚动仍交给原生容器，只替换可见层和交互层
+
+### 2. `ScrollbarOverlay`
+
+文件：
+
+- [ScrollbarOverlay.tsx](/home/ray/dev/linkong/planet/frontend/src/components/Scrollbar/ScrollbarOverlay.tsx)
+
+用途：
+
+- Ant Table 这类内部已有滚动容器的区域
+- 不接管滚动语义，只叠加新的滚动条可见层
+
+当前使用场景：
+
+- 数据源
+- 采集数据
+- 用户管理
+- 设置页
+- 告警页
+- BGP 页面
+
+### 3. `TableScrollRegion`
+
+文件：
+
+- [TableScrollRegion.tsx](/home/ray/dev/linkong/planet/frontend/src/components/Scrollbar/TableScrollRegion.tsx)
+
+用途：
+
+- 为表格滚动区提供统一包裹层
+- 后续新表格页优先复用，不要重复写“表格区域 + overlay scrollbar”样板
+
+### 4. 其他共享组件
+
+- [MarkdownRenderer.tsx](/home/ray/dev/linkong/planet/frontend/src/components/MarkdownRenderer/MarkdownRenderer.tsx)
+- [TableActions.tsx](/home/ray/dev/linkong/planet/frontend/src/components/TableActions/TableActions.tsx)
+
+## 当前状态来源
+
+### 1. 认证状态
+
+文件：
+
+- [auth.ts](/home/ray/dev/linkong/planet/frontend/src/stores/auth.ts)
+
+职责：
+
+- token
+- 当前用户
+- 登录/退出
+
+`App.tsx` 用它判断是否进入登录页。
+
+### 2. 业务数据网关
+
+目前 AI / 态势感知相关服务集中在：
+
+- [http-gateway.ts](/home/ray/dev/linkong/planet/frontend/src/services/situational-awareness/http-gateway.ts)
+- [port.ts](/home/ray/dev/linkong/planet/frontend/src/services/situational-awareness/port.ts)
+- [types.ts](/home/ray/dev/linkong/planet/frontend/src/services/situational-awareness/types.ts)
+
+约束：
+
+- 页面不要直接散落拼 URL
+- 先通过 port/types 定义边界
+- 再由 http/mock gateway 实现
+
+## 当前页面分层建议
+
+### 1. 仪表盘和摘要型页面
+
+例如：
+
+- [Dashboard.tsx](/home/ray/dev/linkong/planet/frontend/src/pages/Dashboard/Dashboard.tsx)
+
+优先目标：
+
+- 页头稳定
+- 摘要卡片先紧凑化
+- 主工作区占据主要高度
+
+### 2. 表格型页面
+
+例如：
+
+- [DataSources.tsx](/home/ray/dev/linkong/planet/frontend/src/pages/DataSources/DataSources.tsx)
+- [DataList.tsx](/home/ray/dev/linkong/planet/frontend/src/pages/DataList/DataList.tsx)
+- [Users.tsx](/home/ray/dev/linkong/planet/frontend/src/pages/Users/Users.tsx)
+- [Settings.tsx](/home/ray/dev/linkong/planet/frontend/src/pages/Settings/Settings.tsx)
+
+约束：
+
+- 优先内部滚动
+- 不要让表格撑爆整页
+- 新表格区域优先复用 `TableScrollRegion` / `ScrollbarOverlay`
+
+### 3. 复杂工作区页面
+
+例如：
+
+- [BGP.tsx](/home/ray/dev/linkong/planet/frontend/src/pages/BGP/BGP.tsx)
+- [Playground.tsx](/home/ray/dev/linkong/planet/frontend/src/pages/Playground/Playground.tsx)
+
+约束：
+
+- Tabs 里的内容不能套同一套高度逻辑
+- 表格 tab、Markdown tab、配置 tab 要各自定义滚动责任
+- AI 结果区、长文本区优先保证最小可读高度
+
+## 当前布局约束
+
+这些原则已经在项目里反复验证过：
+
+1. 父容器高度链要闭合
+2. `min-height: 0` 不能漏
+3. overflow 责任必须明确
+4. 不要用 `overflow: hidden` 掩盖结构问题
+5. 不要为了摘要卡完整显示去压缩主工作区
+6. 自定义滚动条必须是浮层，不得挤压内容宽度
+
+详细经验见：
+
+- [frontend-layout-guidelines.md](/home/ray/dev/linkong/planet/docs/technical/frontend-layout-guidelines.md)
+
+## 当前推荐改动方式
+
+如果后续继续改后台页面，建议按这个顺序：
+
+1. 先确认页面属于摘要页、表格页还是复杂工作区
+2. 先接入现有壳层和滚动语义
+3. 优先复用共享滚动组件
+4. 最后再改视觉和细节交互
+
+不要先写局部 CSS 补丁，再回头补结构。
+
+## 当前明显边界
+
+控制台前端和 Earth 前端不是一套系统：
+
+- 控制台前端是 React + Ant Design 工作台
+- Earth 前端是 `public/earth` 下的独立原生 HUD 系统
+
+因此：
+
+- 不要把 Earth 的 HUD/动画/状态机直接挪进控制台
+- 不要把控制台表格/滚动策略硬套到 Earth HUD

+# UE nDisplay WebSocket 协议草案
+
+## 目的
+
+本协议定义后端到 UE `nDisplay` 集群运行时之间的场景同步契约。
+
+设计目标：
+
+- 由 UE 主节点单点接入后端
+- 使用全量快照重建完整场景
+- 使用增量更新降低同步成本
+- 支持控制帧和显示配置
+- 支持序列号、重放和重同步
+
+## 适用范围
+
+该协议建立在通用 WebSocket 协议之上，参考 [websocket_protocol.md](/D:/work/planet/planet/websocket_protocol.md:1)。
+
+新增的核心内容是 `ue_scene` 频道。
+
+## 连接模型
+
+### 客户端
+
+- UE 主节点连接 `ws://<backend-host>:8000/ws?token=<access_token>`
+- UE 渲染节点不直接连接后端场景通道
+
+### 订阅
+
+UE 主节点建议订阅：
+
+- `ue_scene`
+- `alerts`
+- `dashboard`
+
+## 协议规则
+
+- 每次场景更新都带单调递增的 `sequence`
+- 增量更新必须包含 `base_sequence`
+- UE 如果发现序列断裂，应先发 `sync_request`
+- 服务端优先返回可重放的增量历史；无法重放时返回全量快照
+- 后端始终发送地理坐标，UE 本地负责转成球体世界坐标
+- 控制消息与场景消息分离

+## 场景实体结构
+
+每个场景实体建议包含：
+
+- `id`
+- `entity_type`
+- `revision`
+- `geo`
+- `visual`
+- `metrics`
+- `labels`
+- `status`
+
+示例：
+
+```json
+{
+  "id": "gpu_clusters:123",
+  "entity_type": "gpu_cluster",
+  "revision": 987654321,
+  "geo": {
+    "lat": 35.9327,
+    "lng": -84.3107,
+    "alt": 0.0
+  },
+  "visual": {
+    "style": "pulse_marker",
+    "size": 1.0,
+    "color": "#FF8C42"
+  },
+  "metrics": {
+    "name": "Frontier"
+  },
+  "labels": {
+    "title": "Frontier",
+    "subtitle": "Oak Ridge, US"
+  },
+  "status": {
+    "health": "normal",
+    "alert_level": "none"
+  }
+}
+```
+
+## 同步策略
+
+UE 主节点建议这样处理：
+
+1. 保存本地最后一次成功应用的 `sequence`
+2. 收到增量帧时检查 `base_sequence`
+3. 若 `base_sequence` 不等于本地序列，则立即发 `sync_request`
+4. 如果服务端能重放缺失增量，则按顺序依次应用
+5. 如果服务端无法重放，则接收并应用新的全量快照
+6. 场景更新应在主节点原子提交，再交给集群同步显示
+
+## 服务端重同步规则
+
+服务端建议行为：
+
+- `initial_connect`：直接返回全量快照
+- `manual_resync`：直接返回全量快照
+- `profile_changed`：直接返回全量快照
+- `sequence_gap`：优先尝试从历史缓存中回放增量
+- 如果历史缓存不完整：回退到全量快照
+- 如果客户端已是最新序列：返回空变化增量或保持静默
+
+## 集群职责约束
+
+- 只有 UE 主节点接收后端场景同步消息
+- 渲染节点不直接重放后端消息
+- 服务端表达的是场景意图，而不是每个节点的底层渲染状态
+
+## 推荐的后端扩展
+
+- 为 `ue_scene` 增加更多真实可视化层
+- 将告警/BGP 事件并入统一场景层
+- 为控制命令增加真正的状态持久化与回执
+- 为主节点断线重连补状态恢复策略

+ *
+ * A startup task is registered via registerLayerStartupTask(id, taskFactory).
+ * The taskFactory receives a startup context from main.js and must return an async
+ * function with the signature async (layerDefinition) => void.
+ *
+ * Put a task here only when a layer needs dedicated startup loading work:
+ * - preloading data at boot
+ * - staged loading with progress/loading messages
+ * - post-load UI refresh or warmup
+ *
+ * Do not put plain visibility toggles or persistent UI state here; those still belong

+# BP_GlobeController 接 `ue_scene` 数据接口指南
+
+## 这份文档解决什么问题
+
+这份文档专门讲：
+
+1. 后端 `ue_scene` 已经准备好之后，如何先在本机验证接口
+2. UE 展示端接接口时，消息应该怎么走
+3. `BP_GlobeController` 后续该预留哪些函数和状态
+
+适合当前阶段：
+
+- 你已经有 `Earth_Globe`
+- 你已经有一个能展示地球的 Demo
+- 现在要开始把后端的 `ue_scene` 数据接进来
+
+## 当前后端入口
+
+后端 WebSocket 入口在：
+
+- [backend/app/api/v1/websocket.py](/D:/work/planet/planet/backend/app/api/v1/websocket.py:1)
+
+`ue_scene` 数据构建在：
+
+- [backend/app/core/websocket/ue_scene.py](/D:/work/planet/planet/backend/app/core/websocket/ue_scene.py:1)
+
+协议草案在：
+
+- [docs/ue-ndisplay-websocket-protocol.md](/D:/work/planet/planet/docs/ue-ndisplay-websocket-protocol.md:1)
+
+## 先不要直接进 UE
+
+建议先做一件事：
+
+先在本机验证这条链路是通的：
+
+1. 登录后端拿 `access_token`
+2. 用这个 token 连接 `/ws`
+3. 订阅 `ue_scene`
+4. 发送 `sync_request`
+5. 确认后端回了 `full` 快照
+
+这一步跑通后，再把同样的消息流程搬到 UE。
+
+## 本机验证脚本
+
+仓库里已经补了测试脚本：
+
+- [scripts/test_ue_scene_ws.ps1](/D:/work/planet/planet/scripts/test_ue_scene_ws.ps1)
+
+### 用法
+
+```powershell
+powershell -ExecutionPolicy Bypass -File scripts/test_ue_scene_ws.ps1 `
+  -BaseUrl http://localhost:8000 `
+  -Username 你的用户名 `
+  -Password 你的密码 `
+  -ReadMessageCount 3
+```
+
+### 预期输出
+
+你应该能看到这些消息：
+
+1. `connection_established`
+2. `subscription_confirmed`
+3. 至少一条 `data_frame`
+
+其中第一条 `data_frame` 里：
+
+- `channel = ue_scene`
+- `update_type = full`
+
+如果这一步失败，不要先去 UE 里找问题。
+
+## 连接顺序
+
+UE 主节点后续接接口时，顺序就是下面这样：
+
+1. 登录拿 token
+2. 连接 `ws://<host>:8000/ws?token=<access_token>`
+3. 收到 `connection_established`
+4. 发 `subscribe`
+5. 发 `sync_request`
+6. 收 `data_frame`
+7. 应用 `full`
+8. 后续继续应用 `incremental`
+
+## WebSocket 地址
+
+```text
+ws://localhost:8000/ws?token=<access_token>
+```
+
+## `subscribe` 消息
+
+```json
+{
+  "type": "subscribe",
+  "data": {
+    "channels": ["ue_scene"]
+  }
+}
+```
+
+## `sync_request` 消息
+
+```json
+{
+  "type": "sync_request",
+  "data": {
+    "channel": "ue_scene",
+    "reason": "initial_connect",
+    "last_sequence": null
+  }
+}
+```
+
+## 你在 UE 里要接收的重点字段
+
+### 1. `data.update_type`
+
+可能是：
+
+- `full`
+- `incremental`
+
+### 2. `data.sequence`
+
+每次场景更新都会递增。
+
+UE 主节点要保存自己最近一次成功应用的 `sequence`。
+
+### 3. `data.payload.layers`
+
+`full` 快照时，场景实体都在这里。
+
+重点层包括：
+
+- `satellites`
+- `supercomputers`
+- `gpu_clusters`
+- `submarine_cables`
+- `landing_points`
+- `alerts`
+
+### 4. `data.changes`
+
+`incremental` 更新时，变化都在这里。
+
+每一层会包含：
+
+- `added`
+- `updated`
+- `removed`
+
+## `BP_GlobeController` 建议先预留的变量
+
+### `LastSequence`
+
+- 类型：整数
+- 用途：记录最近一次成功应用的序列号
+
+### `SceneConnected`
+
+- 类型：布尔
+- 用途：当前是否已连上后端 WebSocket
+
+### `PendingFullSync`
+
+- 类型：布尔
+- 用途：是否正在等待全量快照
+
+### `CurrentSceneHash`
+
+- 类型：字符串
+- 用途：记录当前已应用场景的 `state_hash`
+
+## `BP_GlobeController` 建议先预留的函数
+
+### `ConnectWebSocket`
+
+负责：
+
+- 建立连接
+- 进入已连接状态
+
+### `SendSubscribe`
+
+负责：
+
+- 订阅 `ue_scene`
+
+### `SendSyncRequest`
+
+负责：
+
+- 请求 `full` 快照
+
+### `HandleMessage`
+
+负责：
+
+- 解析服务端返回的原始 JSON
+
+### `ApplyFullScene`
+
+负责：
+
+- 清理旧场景数据
+- 按 `layers` 重建当前场景
+
+### `ApplyIncrementalScene`
+
+负责：
+
+- 处理 `added`
+- 处理 `updated`
+- 处理 `removed`
+
+### `GeoToWorld`
+
+负责：
+
+- 把 `lat/lng/alt` 转成球面世界坐标
+
+## 第一个可落地目标
+
+不要一上来就把所有层都接进来。
+
+建议第一阶段只做：
+
+1. 连接成功
+2. 收到 `full`
+3. 先只解析 `gpu_clusters`
+4. 在地球上生成几个测试点位
+
+这样最容易判断问题在哪：
+
+- 是连接没通
+- 还是 JSON 没解析对
+- 还是地理坐标映射有问题
+
+## 当前阶段建议
+
+对于你现在这个 Demo，建议下一步按这个顺序：
+
+1. 先跑 [scripts/test_ue_scene_ws.ps1](/D:/work/planet/planet/scripts/test_ue_scene_ws.ps1:1)
+2. 确认后端确实回 `ue_scene`
+3. 再在 UE 里接登录和 WebSocket
+4. 先只落 `ApplyFullScene`
+5. 最后再接 `ApplyIncrementalScene`
+
+## 一个现实提醒
+
+UE 原生 `WebSockets` 插件更适合 C++ 层接入，不是最友好的纯蓝图体验。
+
+所以如果你下一步要我继续带着落地，我建议走这条路线：
+
+1. 先把协议和测试跑通
+2. 再补一个 UE 侧最小 C++ WebSocket 接收层
+3. 最后把消息转给 `BP_GlobeController`
+
+这样会比纯蓝图硬接稳定很多。

+# UE5.7 连接 `ue_scene` 数据接口实操
+
+## 目标
+
+把当前后端的 `ue_scene` WebSocket 数据接到 UE5.7 工程里。
+
+当前后端入口：
+
+- [backend/app/api/v1/websocket.py](/D:/work/planet/planet/backend/app/api/v1/websocket.py:1)
+- [backend/app/core/websocket/ue_scene.py](/D:/work/planet/planet/backend/app/core/websocket/ue_scene.py:1)
+
+本次补的 UE 侧最小 C++ 文件：
+
+- [Planet.Build.cs](/D:/work/planet/planet/unreal/Source/Planet/Planet.Build.cs:1)
+- [UeSceneWebSocketClient.h](/D:/work/planet/planet/unreal/Source/Planet/Public/UeSceneWebSocketClient.h:1)
+- [UeSceneWebSocketClient.cpp](/D:/work/planet/planet/unreal/Source/Planet/Private/UeSceneWebSocketClient.cpp:1)
+
+## 这一步先做什么
+
+先做最小闭环：
+
+1. UE 登录后端拿 token
+2. UE 连接 `/ws`
+3. UE 订阅 `ue_scene`
+4. UE 发送 `sync_request`
+5. UE 收到原始 JSON
+
+先不急着做完整场景生成。
+
+## 第 1 步：把代码放进你的 UE5.7 工程
+
+你的真实 UE 工程里应该有：
+
+```text
+YourProject/
+  Source/
+    YourProject/
+```
+
+把这里的示例代码内容按模块名改进去：
+
+- `Planet.Build.cs`
+- `UeSceneWebSocketClient.h`
+- `UeSceneWebSocketClient.cpp`
+
+如果你的工程模块名不是 `Planet`，要把：
+
+- `PLANET_API`
+
+改成你自己的模块导出宏。
+
+## 第 2 步：启用插件
+
+在 UE5.7 编辑器里启用：
+
+- `WebSockets`
+- `HTTP`
+- `Json Blueprint Utilities`（可选）
+
+启用后重启编辑器。
+
+## 第 3 步：重新生成并编译工程
+
+如果你是 Visual Studio 工作流：
+
+1. 右键 `.uproject`
+2. 选择“生成 Visual Studio 项目文件”
+3. 打开 `.sln`
+4. 编译 `Development Editor`
+
+## 第 4 步：把组件挂到 `BP_GlobeController`
+
+编译成功后：
+
+1. 打开 `BP_GlobeController`
+2. 点击 `添加`
+3. 搜索：
+   - `Ue Scene Web Socket Client`
+4. 把这个组件挂进去
+
+## 第 5 步：填写后端参数
+
+选中这个组件，在 `细节` 面板里填写：
+
+- `Backend Base Url`：`http://127.0.0.1:8000`
+- `Username`：你的后端用户名
+- `Password`：你的后端密码
+
+默认频道已经是：
+
+- `ue_scene`
+
+## 第 6 步：在蓝图里接事件
+
+在 `BP_GlobeController` 里接这几个事件：
+
+### `On Connected Changed`
+
+连接成功后：
+
+1. 调 `Send Subscribe`
+2. 再调 `Send Initial Sync Request`
+
+### `On Raw Message`
+
+先不要急着解析全部结构。
+
+第一步只做：
+
+1. 把原始 JSON 打印出来
+2. 或保存到字符串变量
+
+这样先确认 UE 确实收到后端消息。
+
+### `On Error`
+
+把错误字符串打印到屏幕和日志里。
+
+## 蓝图推荐连法
+
+### 开始游戏时
+
+1. `开始游戏时`
+2. 调组件的 `Connect To Backend`
+
+### 连接成功后
+
+1. `On Connected Changed`
+2. `分支`
+3. 如果 `bConnected = true`
+4. 调 `Send Subscribe`
+5. 调 `Send Initial Sync Request`
+
+### 收消息后
+
+1. `On Raw Message`
+2. `打印字符串`
+
+## 第 7 步：先验证消息类型
+
+你应该先在屏幕或输出日志里确认这些消息已经进来了：
+
+1. `connection_established`
+2. `subscription_confirmed`
+3. `data_frame`
+
+其中 `data_frame` 的第一条应是：
+
+- `channel = ue_scene`
+- `update_type = full`
+
+## 第 8 步：再接 JSON 解析
+
+当前这一步不建议纯蓝图手搓整个 JSON 结构。
+
+更稳的是：
+
+1. 先在 C++ 里加一个简单解析层
+2. 只抽出 `type`
+3. 只抽出 `data.update_type`
+4. 只抽出 `payload.layers.gpu_clusters.items`
+
+先把 `gpu_clusters` 画出来，再扩到别的层。
+
+## 当前阶段建议
+
+先完成这 3 件事就够了：
+
+1. UE 能成功连接后端
+2. UE 能收到 `full` 快照
+3. UE 能把原始 JSON 打印出来
+
+做到这一步，我们再继续补：
+
+- JSON 结构体
+- `ApplyFullScene`
+- `ApplyIncrementalScene`
+- `GeoToWorld`
+
+## 一句最重要的提醒
+
+现在先别在 UE 里同时做：
+
+- WebSocket 连接
+- 全量 JSON 解析
+- 点位生成
+- 海缆生成
+
+一步一步来，先确认“连通”，再做“可视化”。这样最不容易卡死。
