 - Default to acting directly when the user gives a clear task.
+- For authorized multi-agent work, follow the Coding Agent Model Strategy in
+  `rules.md` workflow: Sol for implementation, Luna for bounded supporting work,
+  and Astra for complex reasoning; the main agent owns final verification.
 - Ask before acting only when the missing decision is risky, cannot be
   discovered from repository context, and no conservative assumption is safe.
 - Read relevant files before editing.

-# Earth 天球背景与日月位置实施方案
-
-## 目标
-
-为 Earth 大屏增加一套真正可用的天文背景层，覆盖三件事：
-
-1. 用真实天球背景替换当前随机星点
-2. 在当前时间下显示太阳与月亮的相对位置
-3. 让太阳方向同时驱动地球受光，形成更可信的昼夜关系
-
-本方案优先追求：
-
-- 与当前 Three.js Earth 架构兼容
-- 风险可控
-- 先落地一版真实感明显提升的 V1
-- 为后续更严格的天文参考系升级预留余地
-
-## 当前现状
-
-当前 Earth 的基础条件已经具备：
-
-- 地球、云层、地形、网格都基于 Three.js，主渲染入口在 [frontend/public/earth/js/main.js](/home/ray/dev/linkong/planet/frontend/public/earth/js/main.js)
-- 地球实体创建在 [frontend/public/earth/js/earth.js](/home/ray/dev/linkong/planet/frontend/public/earth/js/earth.js)
-- 当前所谓“宇宙背景”只是 `createStars()` 生成的随机星点，不是真实星图
-- Earth 已有倾角常量 `EARTH_CONFIG.tiltRad`，位于 [frontend/public/earth/js/constants.js](/home/ray/dev/linkong/planet/frontend/public/earth/js/constants.js)
-- 主循环 `animate()` 已稳定运行，可在其中接入天体更新逻辑
-
-这意味着：
-
-- 不需要重写 Earth
-- 可以在现有 scene/world 层新增一个 celestial layer
-- 第一阶段不必拆 Earth / satellite / cable 的参考系
-
-## 总体策略
-
-采用“两层现实”设计：
-
-### 1. 世界层（world-space celestial layer）
-
-用于放置：
-
-- 天球背景
-- 太阳
-- 月亮
-- 太阳光方向
-
-这些对象不挂在 `earthObj` 上，而是直接放在 `scene` 中。
-
-### 2. 地球层（earth-fixed layer）
-
-继续保持当前结构：
-
-- 海缆
-- 登陆点
-- 卫星点与轨迹
-- BGP 覆盖
-- 地球纹理、云层、地形
-
-这些对象继续挂在 `earthObj` 下，不打断现有交互。
-
-## 为什么先这样做
-
-当前用户交互是“拖动地球本体”，而不是“移动相机绕惯性系观测”。  
-如果现在直接做严格惯性参考系改造，会同时影响：
-
-- `earthObj.rotation`
-- 卫星轨迹与锁定逻辑
-- 海缆与登陆点附着关系
-- resetView / autoRotate / hover / click 等交互链路
-
-所以第一阶段只做：
-
-- 真正的天空
-- 真正的日月方向
-- 不碰现有 Earth 附着对象的语义
-
-## 推荐技术选型
-
-### 天文计算库
-
-推荐：
-
-- [Astronomy Engine](https://github.com/cosinekitty/astronomy)
-
-原因：
-
-- 有 JavaScript 版本
-- 支持 Sun / Moon 的矢量与坐标变换
-- 精度、可扩展性都比轻量太阳高度角库更适合本项目
-- 后续若要加行星、月相、黄道、赤道网，也能继续沿用
-
-不作为主选的库：
-
-- [SunCalc](https://github.com/mourner/suncalc)
-
-原因：
-
-- 更偏本地观察者视角的太阳/月亮高度角
-- 用于“地面日出日落”很好
-- 但不如 Astronomy Engine 适合做真实天球与后续空间参考系扩展
-
-### Three.js 表现层
-
-推荐组合：
-
-- 天球：内翻球壳 + 星图纹理
-- 太阳：`THREE.Sprite`
-- 月亮：`THREE.Sprite` 或小型 `THREE.Mesh`
-- 太阳光：`THREE.DirectionalLight`
-
-参考：
-
-- [Three.js SpriteMaterial](https://threejs.org/docs/pages/SpriteMaterial.html)
-
-## 天球背景资源与星体数据来源
-
-为避免把“视觉背景”和“可计算天体位置”混为一谈，本方案明确分成两类资源：
-
-### 1. 背景资源：全天星图贴图
-
-用于 Phase 1 的“真实天空背景”。
-
-推荐优先来源：
-
-- NASA SVS 的 Tycho 全天星图
-  - [The Tycho Catalog Skymap - Version 2.0](https://svs.gsfc.nasa.gov/3572/)
-- NASA Deep Star Maps 2020
-  - SatelliteMap.space 在 credits 中明确提到其使用了 `NASA Deep Star Maps 2020 - High-resolution star field (1.7 billion stars from Gaia DR2)` 作为星空视觉资源
-  - 这说明行业内成熟实现并不一定直接渲染全部星表点，而很可能先使用一张高质量官方深空星图作为背景层
-- 如需后续替换，也可评估 ESA / Gaia 的全天 sky map 资源
-  - [Gaia DR3 stories](https://www.cosmos.esa.int/web/gaia/dr3-stories)
-
-建议要求：
-
-- 使用官方来源或官方衍生可复用资源
-- 等距矩形投影（equirectangular）
-- 坐标定义尽量明确为赤道坐标展开
-- 分辨率建议至少 `4k`
-- 颜色不要过亮，避免压过 Earth HUD 前景
-- 尽量优先选择官方天文机构已经生产好的深空图，而不是自行拼接低质量星空纹理
-
-建议本地资源目录：
-
-- `frontend/public/earth/assets/celestial/starmap_equatorial_4k.jpg`
-
-### 2. 位置数据：星表与天体计算
-
-用于 Phase 2+ 的“位置正确的星体”。
-
-推荐来源分两层：
-
-- 太阳、月亮位置
-  - 使用 [Astronomy Engine](https://github.com/cosinekitty/astronomy)
-- 恒星位置
-  - 第一优先：Hipparcos / Tycho
-    - [Hipparcos overview](https://www.cosmos.esa.int/web/Hipparcos)
-    - [Hipparcos catalogues](https://www.cosmos.esa.int/web/hipparcos/catalogues)
-  - 第二优先：Gaia
-    - [Gaia DR3 stories](https://www.cosmos.esa.int/web/gaia/dr3-stories)
-
-建议策略：
-
-- V1：背景球壳只用全天星图，不立即生成全量恒星点
-- V2：只挑选亮星（例如星等 `< 5.5`）生成恒星点层
-- V3：如果确实需要更丰富的星场，再逐步扩展到更深星等
-
-这样做的原因：
-
-- 背景球壳负责“天球真实感”
-- 亮星点负责“位置正确、可后续标注和高亮”
-- 不需要一开始就处理数十万甚至数百万颗星
-
-### 3. 对外部成熟实现的参考结论
-
-`SatelliteMap.space` 的公开 credits 提供了一个很有价值的参考样板：
-
-- 图形渲染使用 `TWGL.js`
-- 天文计算使用 `Skyfield` 与 `Astronomia`
-- 星空/天球视觉资源使用 `NASA Deep Star Maps 2020`
-
-这给本项目的启发是：
-
-- “真实感强的天球背景”完全可以先依赖官方高质量深空图
-- “位置正确的动态天体”则应依赖单独的天文计算链路
-- 没有必要在第一版就直接渲染完整星表
-
-因此本项目推荐继续坚持两层拆分：
-
-- 背景层：官方深空图 / 全天星图
-- 计算层：太阳、月亮与后续亮星点
-
-## 如何保证星体位置正确
-
-位置正确不是只看“图看起来像”，而是要统一参考系和转换链路。
-
-### 1. 统一坐标基准
-
-本方案推荐统一使用：
-
-- `J2000` 赤道坐标系作为恒星位置基准
-
-原因：
-
-- Hipparcos / Tycho 资料和大量天文可视化都容易映射到该基准
-- 太阳、月亮也可以通过 Astronomy Engine 转到同一坐标系
-- 这样背景、恒星点、太阳、月亮就能共用一套 sky orientation
-
-### 2. 背景贴图与点位必须使用同一展开逻辑
-
-如果背景球壳使用赤道坐标全天图，那么：
-
-- 亮星点也必须按赤道坐标贴到同一球面方向
-- 太阳/月亮 sprite 也必须按赤道坐标转换后落到同一 world-space
-
-否则会出现：
-
-- 背景银河带是对的
-- 但太阳/月亮或亮星点飘到不匹配的位置
-
-### 3. RA / Dec 到 Three.js 坐标的落点方式
-
-亮星点和日月方向最终都要转成单位球面向量。
-
-概念步骤：
-
-1. 读取赤经 `RA`
-2. 读取赤纬 `Dec`
-3. 转成弧度
-4. 映射到单位球面向量
-5. 再根据 Three.js 当前世界坐标定义做轴向映射
-
-参考公式：
-
-```text
-x = cos(dec) * cos(ra)
-y = sin(dec)
-z = cos(dec) * sin(ra)
-```
-
-实际接入 Three.js 时，需要做一次项目内坐标轴校准：
-
-- 验证 `RA = 0h`
-- 验证 `RA = 6h`
-- 验证北天极
-- 验证银河带主方向
-
-然后确定最终的：
-
-- `x/y/z` 对应 Three.js 哪个轴
-- 是否需要 `z` 取反
-- 是否需要整体再做一个固定 `rotation`
-
-建议把这层显式封装在：
-
-```js
-function equatorialToWorldVector(raRad, decRad)
-```
-
-不要把轴映射散落在不同模块里。
-
-### 4. 背景球壳与恒星点的关系
-
-推荐最终组合：
-
-- 背景层：全天星图球壳
-- 点位层：亮星点
-- 动态层：太阳 / 月亮
-
-这样有三个好处：
-
-- 背景层提供密集真实的天空纹理
-- 亮星点提供位置正确、可扩展的标注基础
-- 太阳/月亮提供与时间相关的真实动态对象
-
-## 数据与资源建议清单
-
-### 推荐首批引入资源
-
-1. 全天星图
-- 来源：NASA Tycho all-sky map
-- 用途：背景球壳纹理
-
-2. 月亮纹理
-- 用途：Phase 4 月相表现
-- 路径建议：
-  - `frontend/public/earth/assets/celestial/moon_albedo_2k.jpg`
-
-3. 太阳 glow 贴图
-- 用途：太阳 sprite halo
-- 路径建议：
-  - `frontend/public/earth/assets/celestial/sun_glow.png`
-
-### 推荐首批数据文件
-
-如果要上亮星层，建议新增一个预处理后的轻量数据文件：
-
-- `frontend/public/earth/assets/celestial/bright-stars.json`
-
-建议字段：
-
-```json
-[
-  {
-    "id": 32349,
-    "name": "Sirius",
-    "raDeg": 101.2875,
-    "decDeg": -16.7161,
-    "mag": -1.46,
-    "colorIndex": 0.00
-  }
-]
-```
-
-建议不要在浏览器里直接吞原始 Gaia 大表，而是先离线裁剪成：
-
-- 只保留亮星
-- 只保留渲染必需字段
-- JSON 或二进制轻量格式
-
-## 资源与数据实施路线
-
-### 路线 A：先做可用版本（推荐）
-
-1. 引入 NASA Tycho 全天图
-   - 或评估替换为更接近 SatelliteMap.space 路线的 `NASA Deep Star Maps 2020`
-2. 实现背景球壳
-3. 用 Astronomy Engine 计算太阳/月亮方向
-4. 暂不做亮星点
-
-优点：
-
-- 最快见效
-- 风险最低
-- 就能明显提升天球真实感
-
-### 路线 B：在 A 基础上增强
-
-1. 离线生成 `bright-stars.json`
-2. 浏览器端渲染亮星点
-3. 后续可加：
-   - 星座线
-   - 亮星名称
-   - 特定星体高亮
-
-优点：
-
-- 背景真实感和“位置正确的可交互星体”同时兼顾
-
-## 代码模块建议细化
-
-### 新增模块
-
-- `frontend/public/earth/js/celestial.js`
-  - 管理天球背景
-  - 管理太阳/月亮
-  - 管理亮星层（后续）
-
-- `frontend/public/earth/js/celestial-data.js`
-  - 资源路径
-  - 星图方向配置
-  - 亮星数据加载（后续）
-
-### 建议函数设计
-
-```js
-export function initCelestialLayer(scene)
-export function updateCelestialLayer(date)
-export function setCelestialVisibility(visible)
-export function disposeCelestialLayer()
-
-function loadStarMapTexture()
-function createSkySphere(texture)
-function createSunSprite()
-function createMoonSprite()
-function getSunEquatorialPosition(date)
-function getMoonEquatorialPosition(date)
-function equatorialToWorldVector(raRad, decRad)
-```
-
-### 推荐后续预处理脚本
-
-如要引入亮星层，建议单独做离线脚本：
-
-- `scripts/build_bright_stars.py`
-
-职责：
-
-- 从 Hipparcos / Tycho 源数据读取
-- 过滤亮星
-- 生成 `bright-stars.json`
-
-这样浏览器端只消费轻量结果，不承担大表解析成本。
-
-## 分阶段实施
-
-## Phase 1：真实天球背景
-
-### 目标
-
-用真实全天星图替换当前随机星点背景。
-
-### 做法
-
-1. 新增一张全天星图纹理
-
-建议路径：
-
-- `frontend/public/earth/assets/celestial/starmap_equatorial_4k.jpg`
-
-纹理要求：
-
-- 等距矩形投影
-- 赤经/赤纬坐标展开
-- 无地平线、无地景遮挡
-- 尽量深色、弱干扰，适合大屏 HUD 叠加
-
-2. 新增天球球壳
-
-新增模块：
-
-- [frontend/public/earth/js/celestial.js](/home/ray/dev/linkong/planet/frontend/public/earth/js/celestial.js)
-
-建议接口：
-
-```js
-export function initCelestialLayer(scene)
-export function updateCelestialLayer(date, camera, earth)
-export function disposeCelestialLayer()
-```
-
-3. 实现一个大半径内翻球体
-
-建议参数：
-
-- 半径：`600 ~ 900`
-- 材质：`MeshBasicMaterial`
-- `side: THREE.BackSide`
-- 不受场景光照影响
-- 始终围绕场景中心
-
-### 验收标准
-
-- 初始加载后背景不再是随机星点
-- 旋转地球时，背景保持为稳定天球而不是跟地球一起转
-- 不明显干扰海缆/卫星/BGP 的前景识别
-
-## Phase 2：太阳与月亮真实位置
-
-### 目标
-
-在当前 UTC 时间下，计算太阳与月亮在天球中的方向，并显示出来。
-
-### 做法
-
-1. 在 `celestial.js` 内封装天体位置计算
-
-建议函数：
-
-```js
-function getSunDirection(date)
-function getMoonDirection(date)
-```
-
-输出统一为 world-space `THREE.Vector3`
-
-2. 太阳显示
-
-- 一个暖色发光 sprite
-- 比月亮更大、更亮
-- 可选添加柔和 halo
-
-3. 月亮显示
-
-- 一个较小 sprite 或 sphere
-- 灰白偏冷色
-- 后续 Phase 3 再做月相
-
-4. 更新频率
-
-不要每帧重新做完整天文计算，建议：
-
-- 每 30 秒或 60 秒重算一次真实位置
-- 渲染帧内做平滑过渡
-
-### 验收标准
-
-- 页面可见太阳与月亮两个对象
-- 时间变化时位置会更新
-- 日月不会跟随地球局部旋转而错误附着
-
-## Phase 3：太阳驱动地球受光
-
-### 目标
-
-让地球光照方向与太阳方向一致，不再使用写死的固定主光。
-
-### 做法
-
-1. 替换或接管当前主定向光
-
-当前 [frontend/public/earth/js/main.js](/home/ray/dev/linkong/planet/frontend/public/earth/js/main.js) 中 `addLights()` 里用了固定方向的 `DirectionalLight`。
-
-建议改为：
-
-- 保留环境补光
-- 主太阳光方向由 `sunDirection` 决定
-
-2. 太阳光参数建议
-
-- `DirectionalLight` 颜色偏暖白
-- 强度略高于当前主光
-- 保留一个弱背光作为氛围补偿，避免背面过死黑
-
-3. 先不做物理级大气散射
-
-第一版只要求：
-
-- 亮面与暗面方向真实
-- 云层和大气仍保持当前风格
-
-### 验收标准
-
-- 地球明暗面会随太阳方向改变
-- 太阳 sprite 和地球亮面方向一致
-- 不破坏现有海缆、卫星、BGP 的可见性
-
-## Phase 4：月相与天文细节增强
-
-### 目标
-
-在日月真实位置基础上增加更强的“天文可信度”。
-
-### 可选项
-
-1. 月相
-
-- 根据日月夹角计算 illuminated fraction
-- 用月相纹理或 shader 表达盈亏
-
-2. 赤道/黄道辅助线
-
-- 可作为开发调试层，不默认显示
-
-3. 太阳 terminator 增强
-
-- 给地球夜面加入更自然的 night tint
-- 未来可叠加城市夜光纹理
-
-4. 天文时间入口
-
-- 设置中加入“当前时刻 / 指定时刻 / 加速时间”模式
-
-### 验收标准
-
-- 月亮不再只是一个静态圆点
-- 后续扩展行星或观测模式时无需推倒重来
-
-## Phase 5：严格参考系升级（可选，不作为 V1 必做）
-
-### 目标
-
-把 Earth 从“用户旋转球体”升级为“真实地球姿态 + 用户观察姿态”的双层模型。
-
-### 需要处理的问题
-
-- 地球自转角与 UTC 的一致性
-- 赤道坐标系、地固坐标系、相机交互层分离
-- 卫星轨道显示与 Earth 旋转同步关系
-- resetView 和 autoRotate 的语义重定
-
-### 风险
-
-这一步会影响：
-
-- [frontend/public/earth/js/main.js](/home/ray/dev/linkong/planet/frontend/public/earth/js/main.js)
-- [frontend/public/earth/js/satellites.js](/home/ray/dev/linkong/planet/frontend/public/earth/js/satellites.js)
-- [frontend/public/earth/js/cables.js](/home/ray/dev/linkong/planet/frontend/public/earth/js/cables.js)
-- [frontend/public/earth/js/controls.js](/home/ray/dev/linkong/planet/frontend/public/earth/js/controls.js)
-
-因此不建议与 V1 同时推进。
-
-## 代码改造清单
-
-## 1. 新增文件
-
-- [frontend/public/earth/js/celestial.js](/home/ray/dev/linkong/planet/frontend/public/earth/js/celestial.js)
-
-职责：
-
-- 管理天球背景、太阳、月亮
-- 对外暴露 init/update/dispose
-
-## 2. 修改 `constants.js`
-
-文件：
-
-- [frontend/public/earth/js/constants.js](/home/ray/dev/linkong/planet/frontend/public/earth/js/constants.js)
-
-新增：
-
-```js
-export const CELESTIAL_CONFIG = {
-  sphereRadius: 800,
-  updateIntervalMs: 60000,
-  sunSpriteScale: 28,
-  moonSpriteScale: 16,
-  sunLightIntensity: 1.25,
-  ambientIntensity: 0.28,
-  backLightIntensity: 0.18,
-};
-```
-
-## 3. 修改 `main.js`
-
-文件：
-
-- [frontend/public/earth/js/main.js](/home/ray/dev/linkong/planet/frontend/public/earth/js/main.js)
-
-主要改动：
-
-1. `init()` 中：
-   - 初始化 celestial layer
-2. `addLights()` 中：
-   - 把固定太阳光改成可更新的 celestial sun light
-3. `animate()` 中：
-   - 每帧调 `updateCelestialLayer()`
-4. `destroy()` 中：
-   - 清理 celestial 资源
-
-## 4. 修改 `earth.js`
-
-文件：
-
-- [frontend/public/earth/js/earth.js](/home/ray/dev/linkong/planet/frontend/public/earth/js/earth.js)
-
-主要改动：
-
-- `createStars()` 逐步退役
-- 第一阶段可先保留作为 fallback
-- 当真实星图加载成功后，不再显示随机星点
-
-## 5. 新增资源
-
-目录建议：
-
-- `frontend/public/earth/assets/celestial/`
-
-建议至少包含：
-
-- `starmap_equatorial_4k.jpg`
-- `sun_glow.png`
-- `moon_albedo_2k.jpg`
-
-## 数据流设计
-
-```mermaid
-flowchart TD
-    A["main.js:init()"] --> B["initCelestialLayer(scene)"]
-    B --> C["创建天球球壳"]
-    B --> D["创建太阳 sprite + 主定向光"]
-    B --> E["创建月亮 sprite"]
-
-    F["animate()"] --> G["updateCelestialLayer(now, camera, earth)"]
-    G --> H["Astronomy Engine 计算 Sun/Moon 方向"]
-    H --> I["更新 sun sprite / moon sprite 位置"]
-    H --> J["更新太阳 DirectionalLight 方向"]
-    J --> K["地球昼夜方向变化"]
-```
-
-## 风险与注意事项
-
-### 1. 星图投影方向容易反
-
-这会表现为：
-
-- 星图左右镜像
-- 赤经方向颠倒
-- 日月位置和背景对不上
-
-建议：
-
-- 先做一个开发调试模式
-- 显示赤经/赤纬参考点，快速校正纹理朝向
-
-### 2. 不要让天球跟随 Earth 旋转
-
-天球背景和日月必须属于 scene/world，而不是 `earthObj`。
-
-### 3. 不要每帧做重型天文计算
-
-真实位置更新应节流，否则会浪费 CPU。
-
-### 4. 月亮先求“方向正确”，再求“月相精致”
-
-月相属于第二步优化，不应阻塞 V1 上线。
-
-## 推荐实施顺序
-
-1. 新建 `celestial.js`
-2. 用星图球壳替换随机星点
-3. 接入 Astronomy Engine
-4. 加太阳/月亮 sprite
-5. 用太阳方向驱动主光
-6. 再决定要不要做月相和更严格参考系
-
-## 最终建议
-
-对于当前 Planet Earth，最稳妥的方案是：
-
-- 先做真实天球背景
-- 再做真实太阳/月亮方向
-- 再让太阳驱动地球受光
-- 暂时不做 Earth 参考系重构
-
-这样可以在不破坏现有 Earth 交互和图层系统的前提下，显著提升空间感、真实感和演示说服力。

-# 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
-
-## Satellite Footprint Follow-Up Items
-
-从技术文档迁出的 footprint 后续项，作为卫星覆盖能力的计划 backlog：
-
-1. 为 `iridium-next` 新建独立 footprint adapter。
-2. 在 UI 上补一个只读提示，让用户知道当前卫星是否支持 footprint。
-3. 如果未来拿到 GEO beam contour / operator metadata，再为 GEO 开 operator-specific footprint。

-`compute_history.py` stores controlled imports from the reviewed research plan, including annual observations, sources, and a version. Reference periods and publication dates are distinct; unknown publication days remain unspecified. `/api/v1/data-products/compute/series` offers global share, fixed US + China bilateral share, and available FP32 absolute observations. Innovation gaps are independent and never expanded into inferred national scores.
+`compute_history_defaults.json` ships the original report data. `compute_configuration.py` reads a complete override from the `compute_comparison` category in `system_settings`; absent records use bundled defaults without migrations or manual initialization. `compute_history.py` performs same-year aggregation.

+Under the same prefix, `GET/PUT /configuration` and `POST /configuration/reset` require admin/super_admin. Writes accept `{revision, config}` and reset accepts `revision`. Pydantic validates canonical countries, finite values, share totals, duplicate metric/year pairs and report references; each metric/year has one report basis. PostgreSQL category uniqueness and row locking serialize first writes and updates; stale revisions return 409. Configuration and before/after audit records commit in one transaction. Reset removes the override so subsequent reads use the current bundled defaults. `version` is a configuration revision, while `reviewed_at` is the supplied review date. Admin-curated data is not automatically labeled official. Source URLs are references, not scrape instructions.

Epoch excludes planned, decommissioned, superseded, and suspected duplicate records; TOP500 means list observations. Cross-source deduplication remains pending. Historical cutoffs use collection time, never pretending a recently fetched old source was available earlier. Geographic results are bounded and report truncation; total record counts are independent of this limit. Official site helpers are keyed by exact `source` + `source_id`; their access-map centers are site-level references only and retain their official URL in `source_note`.

+### CelesTrak download windows and caching
+
+Both active and fallback-group downloads skip HEAD preflight and send GET directly: a preflight may consume the upstream download allowance before the body request. Valid complete cache entries are reused for two hours, then refreshed with conditional GET when validators exist, or ordinary GET otherwise. A 304 reuses validated cache; only the explicit “GP data has not updated” 403 permits a valid-cache fallback. Other 403 errors remain failures. Fallback groups also respect cache age rather than reusing old files indefinitely.
+
+A nonempty GP record list is validated in `.part` before atomically replacing the cache; failed downloads preserve the previous valid payload. Length comes from the GET response, and compressed wire length is not compared with decoded bytes. Other collectors retain HEAD metadata and Range resume support. Restoring a raw cache does not populate the database: trigger a new collection task afterward.

+
+### Earth news encoding
+
+Before parsing RSS/Atom, `earth_news.py` selects encoding from the BOM, HTTP charset, XML encoding declaration, then UTF-8, and decodes strictly. GBK/GB2312/GB18030 feeds no longer silently replace Chinese bytes with corrupted text. Unknown encodings or invalid bytes produce `format_error` instead of damaged titles. `test_earth_news_encoding.py` covers titles, summaries, display serialization and failure status.

 # Earth Frontend Context
 
+## HD surface and atmosphere materials
+
+The visible HD surface uses a single-draw ShaderMaterial in `earth-surface-material.js`, retaining the R+0.48 mesh, depth policy and surface pick target. The existing controller still switches all four 8K maps, updates the sampler and disposes the previous texture only after success. Normals, view direction and astronomical sunlight share world coordinates. Land is matte; water has grazing-angle cool reflection without a white specular lobe. The existing geographic land/ocean texture owns the optical mask independently of border visibility, with a conservative chroma fallback until loaded and reflection suppression over ice. Original JPEGs are neither repainted nor downsampled.
+
+Color textures are tagged sRGB with mipmaps. The r128 surface shader decodes sRGB; r160 uses hardware texture decoding. Both combine light in linear space and encode once. A local filmic curve affects only the surface instead of enabling global ACES exposure on the sky and data layers. The terminator spans normal dot products [-0.075, 0.16]; night shading has its own geographic texture ghosting and cool ambient branch. A 0.55 power of the locally tone-mapped texture retains shadow variation, followed by separate muted land and deep-indigo ocean tints and low ambient floors. Day/night mixing remains linear with one final sRGB output. Day exposure and reflections are unchanged; no synthetic city lights are added. One R×1.025 BackSide/Additive shell replaces the three rim shells, with depthWrite=false and depthTest=true; inner scattering is part of the surface pass. Independently switchable clouds use matte day/night shading at renderOrder 1.1. The sky uses the existing `starmap_deep_8k.jpg` without a tint overlay.

+Compute cards read annual observations from `/api/v1/data-products/compute/series`; the admin Compute comparison section is the maintenance entry point. `compute-topic.js` fetches with no-store, listens for same-origin `planet-compute-configuration` notifications, and checks every 60 seconds while visible and enabled, plus when the page becomes visible. Observation refresh does not reload facility layers. `destroy()` releases the timer, channel and visibility listener. Country membership, full regional coverage and missing-value semantics remain backend-owned.

 ## Surface texture provenance
 
 On 2026-09-21, `assets/8k_earth_daymap.jpg` was replaced with an 8192×4096 Web derivative of the paired Natural Earth I raster. Its loading path and rendering code remain unchanged. The source is a 16200×8100 EPSG:4326 image; the previous JPEG is preserved byte-for-byte under `resources/earth/archive/2026-09-21/`. Source/license records, the catalogue versus embedded-version discrepancy, SHA256 hashes, JPEG parameters, and recalculated world-file metadata live in `resources/earth/natural-earth-1/`. Large originals remain in Git-ignored `downloads/earth/`, outside the frontend release bundle.
 
-The base-map selector defaults to Original basemap, listed first and saves the source chosen in the display menu. Natural Earth I remains available alongside “Original basemap”, a byte-identical copy of the September 21, 2026 archive; NASA 21K is source archive material only, while runtime delivery stays at one 8K texture. A new source replaces the old GPU texture only after successful loading and releases the old one then; failures retain the old texture and stale responses cannot overwrite the current source. This is a source switch, not an additional rendering layer. The physical texture is JPEG sRGB, does not bake political borders, and detailed boundary alignment is not yet validated. The starfield is restored byte-for-byte to commit `83a10a6c`: `celestial.js` matches that commit, `skyTint` and `skyBrightness` are removed, and `brightStarOpacity` is back to `0.88`; star density and color are no longer calibrated. The HD overlay uses a white `MeshBasicMaterial` with opacity `1` and `toneMapped:false`, with `texture-colors.js` centralizing sRGB read/write. The 0.128 path uses `encoding` plus `LinearTosRGB`; the 0.160.1 path uses `colorSpace` plus the normal colorspace fragment. There is no Phong white-light or colored twilight overlay, blue night tint, `cameraBoost`, or shoulder curve; daylight neutral scaling keeps brightness at or below the source maximum, and dark mode only applies neutral scaling. The original texture asset is unchanged. Natural Earth is intrinsically pale; this does not claim missing detail was restored. Earth still supports the Three 0.128 import-map runtime and frontend package Three 0.160.1 runtime, and WebGL1 derivatives remain enabled for `fwidth`.

-Day/night shading uses a narrow smooth transition centered on the solar horizon (normal dot product ±0.12). The day side is capped at the source brightness; night-side linear illumination is 0.24, rising smoothly to at most 0.60 in source shadows to retain dark ocean and forest detail. Shading uses a neutral scalar without added exposure, colored veils, rendering passes, or textures.
 
 Basemaps and TV channels share `hud-select-menu.js` for the HUD popover, list, selection mark, keyboard navigation, and positioning; `tv-source-menu.js` only adapts channel copy. Basemaps disable search, pagination, and counts. The trigger owner identifies popover clicks as internal to the mobile drawer.
 This document describes the current real structure of the Earth display frontend. The focus is on helping future changes to the HUD, layers, media panel, real terrain, and BGP visualization avoid repeating past structural and state-sync pitfalls.

Do not make these interaction proxies draw individually again or return a render batch as the detail-card business object.

Reload, clear, and altitude changes must terminate prior work so stale snapshots cannot resurrect cleared layers.

 The real satellite altitude preference is persisted by `controls.js`, while the rendering state lives in `satellites.js`. When enabled, the real radius from SGP4 is compressed logarithmically into the current Earth visual radius range. When disabled, satellite dots, trails, and predicted orbits all return to the legacy same-sphere display. Toggling this setting must refresh satellite positions and clear trail buffers so a trail never mixes both height models. `maxRealAltitudeOffset = 25` is a visual cap tuned for the current camera and `earthRadius = 100`: GEO / MEO remain clearly higher than LEO, but the highest orbits stay within about 25% beyond the globe radius so selection targets, red trails, and the globe do not feel disconnected.
 
-SGP4 propagation returns an inertial-frame position, so it must not be drawn directly as Earth-fixed longitude / latitude. `satellites.js` uses `gstime` to convert ECI/TEME positions to ECF, then maps that result into the same Three.js axes as `latLonToVector3()`. Satellite dots and short trails use Earth-fixed coordinates for each sample time, representing the object's current position relative to the globe surface. The locked predicted orbit uses the `gstime` from the lock moment for the whole future orbit, projecting the inertial orbit plane onto the current globe pose; that keeps the line closed and keeps the visual orbit inclination aligned with the details card. Fallback predicted orbits must also use a real RAAN + inclination orbital-plane formula, not treat inclination as a constant latitude.

The locked predicted orbit uses the `gstime` from the lock moment for an open full-period prediction curve, projecting the inertial orbit plane onto the current globe pose. No first vertex or closing chord is appended; arc-length highlights travel toward increasing prediction time, and visual inclination stays aligned with the details card. Fallback predicted orbits must also use a real RAAN + inclination orbital-plane formula, not treat inclination as a constant latitude.
 
 Boundary precision is stored separately by `country-boundaries.js` under `planet.earth.boundaries.highPrecisionEnabled`. When high precision is off, Earth keeps using the bundled low-precision `countries-admin0.min.geojson` fallback even if high-precision manifest/PMTiles files exist locally. When high precision is on but the artifact is missing, the Earth toolbar settings call `/api/v1/earth/boundaries/build` and poll progress. After success, `reloadCountryBoundaries()` hot-swaps the boundary layer without refreshing the page. Boundary hover is independent from interactable hover: a country polygon remains highlighted whenever the surface coordinate is inside it, while the tooltip can still prioritize a satellite, vessel, BGP marker, or other interactable.

-`globe-navigation.js` maps zoom to `sqrt(R² + (D₀² - R²) / zoom²)` with minimum surface clearance and the matching inverse. The 100% camera pose remains unchanged; 500% stays outside the globe. Mouse and single-touch dragging use ray/sphere intersections and quaternion rotation to keep the grabbed surface under the pointer, without an empirical sensitivity multiplier or frame-by-frame catch-up. Auto-rotation is suspended during dragging and pinching. Release inertia follows the measured axis; paused releases and cancellation do not fling. Returning from a pinch to one finger rebases the grab point. Click suppression uses displacement from pointer-down, including slow drags.
+`globe-navigation.js` retains the safe zoom-distance mapping. Mouse and single-touch drags uniformly use legacy screen deltas, 0.18 smoothing and release inertia, including movement outside the globe silhouette; ray/sphere intersection no longer gates dragging. Normal zoom retains legacy sensitivity. Once the globe exceeds the viewport, a smooth surface-distance/viewport cap limits excessive rotation at extreme zoom. Horizontal motion uses geographic yaw, vertical input changes tilt, and quaternion math prevents multi-revolution reversal. Pinch transitions and pointer capture remain intact.
 
-
-Interactable clustering is selected per layer through `cluster.strategy`. `stable-spherical` uses discrete zoom bands and local 3D bucket clustering, so BGP, compute centers, and Earth interactables do not regroup while the globe rotates inside the same band. `dynamic-screen` keeps projection-based clustering, and `none` disables it. Vessels explicitly disable clustering and avoidance so incremental updates do not rebuild cluster topology. Stable cluster dots stay rigidly aligned to their 3D centroid projection and do not participate in 2D avoidance. See [Earth Interactable Clustering](/home/ray/dev/linkong/planet/docs/technical/en/earth-interactable-clustering.md) for strategy configuration and tuning.
+Surface markers retain category icons and fixed geographic cluster membership. Numbered solid circles expand through a 320ms tween above 250% zoom; zoom never regroups members, and 500% has no aggregate badges. Vessels retain independent heading arrows without clustering. See [Earth Interactable Clustering](earth-interactable-clustering.md).
 
 Wheel input has two paths. Traditional mouse wheels keep the 10% step and short animation, using `wheelZoomTarget` as the logical base for continuous wheel input. Trackpads and high-precision wheels use the pixel delta for continuous zoom and call `setZoomLevel()` directly instead of passing through the 10% stepped animation. The trackpad path also filters a short-window, old-direction residual delta after a real direction change so inertia tails do not pull a just-reversed zoom back in the previous direction.

-`spatial-callouts.js` delegates layout to `spatial-callout-controller.js` and reuses `CalloutConnector` with stable region IDs. Layout is event-driven and retains valid old rectangles while work is pending; the projected source line follows the globe continuously. The layout reference is the direction of the actual source exit point, so a card stays near the object side instead of being pulled from a top-left geographic point to an opposite corner. Neighboring same-sector placements, shorter connectors, and fewer crossings are preferred; the solver may exchange free positions for at most three rounds rather than relayout everything each frame. In fullscreen Earth, nearby foreground positions are allowed so cards of normal size do not cross the whole globe merely to avoid it. In slow mode, sustained direction drift or connector crossings must persist for 1.8 seconds before proposing a joint reflow. Automatic proposals are at least 8 seconds apart and need an improvement of at least 18% plus a minimum absolute gain. Manual/inertial input retains the 72ms/12px response budget. Expansion and manual placement grant 12 seconds of reading time; hover, keyboard focus and dragging continue to lock a card, while residual pointer focus does not lock it forever. Manual placement is a preference: after its hold, automatic repair requires at least 45 degrees of source direction change. Restored positions are not permanent pins. Rear connectors retain the globe-outline cue without changing card identity. Local position/size persistence and reset-to-auto are part of the controller. A `ResizeObserver` handles resizing and collapse; configuration and source windows retain shared drag handles.
+`spatial-callouts.js` provides geographic projection and shared scopes; `spatial-callout-controller.js` owns stable peripheral reading slots. `callout-dock-layout.js` treats the central observation area as a hard obstacle, retains valid placements first, then places new or affected cards. Rotation, front/rear changes, connector crossings and length do not request reflow. Only card-list changes, deliberate expand/drag actions, viewport changes and HUD-space changes do. Limited space preserves full cards and permits peripheral overlap, without automatic folding, grouping or font reduction. settleCardDrop validates the released position: valid drops stay, while out-of-bounds or central drops settle to a nearby valid position. Peripheral overlap remains allowed. Persistence records the committed destination, and hovering cannot pause a correction inside the center. Restored positions use the same validation; manual reset controls and handling are removed. Starting a drag raises that card above all regional cards and retains its priority until another card is dragged. Compute and news cards share stacking levels; configuration and evidence panels remain above them.
 
 Object presentation is shared through `PresentationController` and the new object-callout anchor/layout path. A click on a BGP, compute, vessel, satellite, or cable object draws the connector before placing the adjacent card. The source anchor begins at the actual click or original region label, then follows a visible highlight geometry sample as rotation approaches occlusion. The stable `layoutReferencePoint` is derived from the actual connector exit direction, so `packDirectionalEdgeCallouts` keeps cards on the corresponding screen edge and leaves the globe's center open; a card may move inward only when that edge lane is unavailable, and it may never cover its own connector exit point. The bounded joint assignment considers up to 24 beam states and 32 candidates, avoids existing HUD rectangles, then allows at most three safe exchanges to reduce directional crossings; the previous solver remains a fallback and the work is not a full relayout every frame. A slow source-direction gate also checks whether the actual card target reverses more than 90 degrees from the source before committing a change. Manual drag and hover locks take priority. The source point itself remains a per-frame visual connection target; fixed objects track live positions while cards remain draggable. Rear-side objects retain a globe-outline direction cue, a subdued connector, and a hollow source point; these are orientation guides rather than geographic points. Country candidates are capped at 96 with a hard limit of 128 and cached, so GeoJSON is not scanned every frame. Compute cards keep their original point independent from dynamic source-point movement, and the shared card endpoint slides along the obstacle perimeter. Cable presentation prefers the true ray-hit local point, then samples highlighted geometry by `cableId`. Mobile keeps the existing mini popup and opens drawer details. A stale asynchronous presentation must never dismiss a newer selection.
 
 `configVisible` and `cardsEnabled` are separate. X/Escape closes only configuration; disabling the switch releases connectors and restores the previous map query/layer state. Configuration and source windows bind HUD typography directly so reparenting cannot enlarge their text. The main card presents the selected compute metric as a large share percentage or an absolute value with unit, observation year, historical context, and source entry. Missing comparable data is explicit; no empty trend chart is rendered without observations. Facility records and coverage remain complete in the expanded auxiliary area, where sample counts are evidence context rather than a compute value or global coverage rate. Long lists open only when needed. Mobile preserves the same single metric meaning in its accordion. Local position/size persistence and reset-to-auto remain available. Stable DOM, dimensions, and reading state survive updates, and stale responses cannot re-enable cards.
 
-Motion presentation uses the shared `main.js` input state. Sustained drift or crossings trigger a joint assignment, rather than each card competing independently for leftover slots. `callout-region-path.js` provides the short connection and terminal stub used both for rendering and intersection scoring. Candidate paths are precomputed and layout states are cloned only after pruning. Existing cards remain visible during planning; queued reflows survive frame throttling.
+Globe dragging and inertia only pause card motion progress; they never replace committed destinations. Connector anchors follow geographic projection independently of card placement.

+### Satellite particles and smooth rendering
+
+Satellites use one `THREE.Points` batch with `PointsMaterial`: a 32×32 white disc texture of radius 0.42, `alphaTest=0.5`, and `sizeAttenuation=false`. The dark backdrop batch and simulated sphere lighting are removed. `satellite-display.js` calibrates against satellitemap screenshot pixels: point squares are 2.4px at zooms up to 150% and 8px at 500%, with a smoothstep transition. The disc fills 84% of the square, yielding visible cores of about 2px and 6–7px respectively. Blue/orange/green/purple/rose use the reference palette directly without the prototype's extra exposure. Point sizes retain the DPR-cap-2 adjustment without reducing globe resolution. Ordinary breathing defaults off but remains an opt-in setting. Existing hover/selected rings, halos, open predicted orbits and forward-flow animation remain intact.
+
+Real GP/TLE propagation stays in the Worker at 250ms intervals. `satellite-motion.js` caches sample radii and interpolates radius-preserving positions each frame, shared by points, picking, trail tips, selection rings and coverage. `satellite-trail-geometry.js` merges redundant ribbon segments only when the projected error remains below 0.2 pixels across supported zooms. All satellites and 10 history samples are retained; curved or near-camera trails keep their original segments. Only active buffer ranges are uploaded. Trail width is capped at 60% of the point size and tapers toward the tail, avoiding a thick fragmented rim at distant views. `satellite-footprint-geometry.js` retains the full 260×170 coverage grid, created once. The vertex shader evaluates the same surface projection, while local basis and extent uniforms update each frame instead of rebuilding tens of thousands of vertices. Starlink/Iridium footprints share blue `#3399ff`; sunlight changes opacity only, with real coverage models preserved.
+
+`SATELLITE_CATEGORIES` owns real inclination categories and the blue/orange/green/purple/rose/gray palette. Selecting a satellite automatically switches to its legend. Legend categories directly control points, trails, labels and picking; hiding a selected category clears selection and coverage. Layers and settings have no separate filter entry. Explicit search selection re-enables its category. `satellite-labels.js` shows actual names and models (NORAD identifiers when unavailable) at the configured zoom threshold (**400%** by default, adjustable from **250% to 500%**). The slider below Close-up labels sets a persisted desktop/mobile count limit from 5 to 36 (default 36), immediately rescanning candidates on change. Actual visible counts still depend on available positions and occlusion. It checks occlusion and overlap in the central 65% of the view, scans candidates every 160ms and follows active labels each frame.
+
+Settings → Display → Show FPS persists through `shared.showFps`, defaulting off. `frame-stats.js` displays actual frame-interval statistics beside the brand, updating once per second; its native tooltip contains mean interval, P95, main-thread CPU time, draw calls and an approximately 30-second rolling mean FPS (total frames / total duration, not an average of per-second rates). Slow foreground frames remain in the sample; visibility changes reset the sampling window. A single high-FPS sample is not a sustained-performance guarantee. Performance acceptance uses an actual canvas of at least 1920×1080, samples at least 30 seconds and targets a mean of 60 FPS while allowing occasional low frames. Compare distant and 400% views with matching viewport, complete data, layers and playback state, and verify category hiding, search selection and FPS persistence after reload.
+
+The boundary loading tint, land fill, base and HD layers share the `earth-surface.js` geometry factory. Tint and fill share R+0.32, fixing pre-texture diamond rings without changing boundary/HD controls. Intersection and far-zoom depth margins are covered by `earth-surface.test.js`; see [render layer order](earth-render-layer-order.md).
+
+Cables and landing points share HD-surface coordinates through `cable-surface.js`. `cable-batches.js` controls related halos with per-instance emphasis cleared on deselection. `interactable.js` uses `surface-marker-occlusion.js` for whole-badge visibility and picking near the limb. BGP change events retain their original icons; collectors use activity-colored broadcast badges. Sky material uses the original brightness (multiplier 1.0).
+
+`toolbar-hover.js` owns the zoom submenu and radial toolbar as one state machine. Magnifier hover opens zoom; trigger, transparent gap bridge and vertical controls form a continuous keep-open region. Leaving first runs the submenu's 220ms exit, then checks the latest pointer location and pinned state before collapsing the parent. Remaining in the radial wake region or pinning the parent closes only zoom; reentry cancels stale timers. CSS hover/focus-within no longer owns visibility independently. Zoom clicks retain parent pinning, with keyboard and touch entry preserved.
+
+The radial menu inherits global `--hud-scale` (1920×1080 reference, clamped to 0.7–1) instead of fixing its scale at 1. Buttons, icons, fan radii, bottom spacing and the zoom submenu scale together. Base fan coordinates are scaled in CSS transforms; hover wake bounds use the same coordinate scale to prevent hit-region drift under DPI changes. Scaling changes geometry only, preserving animation timing and pinned/hover state transitions.
+
+### Sky color output
+
+The star map is decoded as sRGB. `celestial.js` uses shared `preserveTextureOutput()` to encode only the sky material back to display sRGB. The Three.js r128 renderer retains its existing global linear output so Earth, satellites and other layers remain unchanged. `skyBrightness=1.0` retains source brightness; missing output encoding displays decoded dark values directly and cannot be corrected by raising the multiplier alone. Validate with the same map, camera and orientation, comparing rendered pixels and the 1.0/1.5 response instead of checking asset loading only.
+
+
+### Direct legend filtering
+
+The current interactive object continues to determine the legend mode; enabling a layer with its existing switch also selects its legend, without adding a filter entry. Cables filter by route name, compute facilities by type, vessels by type and anchored state, and BGP by severity and collector activity. Coverage and impacted-region entries control their respective effects. The geographic legend separately controls lines, land fill and ocean fill without changing the shared land mask data. The obsolete BGP connections/hubs entry is removed.
+
+`legend-filters.js` owns independent per-mode session filters. `legend.js` renders shared desktop/mobile toggle buttons with `aria-pressed`, preserving keyboard focus when refreshed. `interactable.js` filters draw batches, cluster candidates and picking while retaining complete source data, counts and object identities. Live vessel type changes, data reload and layer toggles respect filters. Hiding a selected item clears its card and overlays; explicit search selection reveals its category. Vessel track requests are versioned so late responses cannot resurrect a hidden track.
+
+### Stable cards and display preferences
+
+`callout-rest.js` retains a 450ms interaction-settle gate and subtle floating capped at 1.5px. Hover, keyboard reading, dragging and reduced-motion pause the float. Decorative offsets never enter persistence or placement solving, and the central boundary remains protected.
+
+Display settings add `shared.satelliteLabelsEnabled` (true by default), `shared.satelliteLabelMinZoom` (2.5–5, default 4) and `shared.skyBrightness` (0–2, default 1). Desktop/mobile controls, reload and reset share runtime state. Sky brightness multiplies the sky material in linear space with its existing local sRGB output, leaving Earth exposure unchanged. Compute legend counts reflect located types. Chip and stacked SVG glyphs remain mapped to `site_type`; a GPU-only dataset does not invent other types or coordinates.
+
+All destinations and legal routes are decided before presentation changes. `callout-dock-motion.js` uses a 240–420ms tween; `callout-routing.js` only plans static obstacle avoidance. Pauses retain progress and destination. Layout and movement never change collapse state. If a full-card route is unavailable, use its final destination directly instead of temporarily folding the card. Continuous scoring, staged yielding, central fallback and committing intermediate coordinates have been removed.
+
+
+### Cluster badges and Spiderfy
+
+Ordinary surface markers retain GPU batches. Each aggregate uses the same projected children in `cluster-presentation.js` through collapse, expansion and the final resting state. A 26px solid numbered circle represents the group, with an amber ring for mixed categories. Membership changes only with data or filters, never through intermediate groups while zooming.
+
+`cluster-motion.js` drives a 320ms cubic tween after visible icons are prepared and decoded, with encoded textures cached. Children interpolate from the group center to their real projections; `marker-stack.js` owns final display offsets. Animation and resting endpoints retain the same DOM nodes, with continuous reversal.
+
+The UI's `globeZoomForDistance()` expands groups above 250%, with return hysteresis and no aggregate badges at 500%. Only co-located or extremely close geographic anchors (about 0.00015 degrees) share a compact cross-layer stack. Screen overlap and coarse city buckets never merge different locations. Each icon retains its own real projection as its baseline, with the entire stack bounded to 24px per axis and small groups exposing approximately 8–12px edges. Stable IDs define resting order; selecting a rear item brings it forward, with projected children at `z-index: 1000` and unclustered locked overlays at shared `renderOrder >= 100`, so focus stays above overlapping layers; clearing focus restores its slot. Ordinary expansion ends exactly at real projected positions; coordinates and marker positions remain unchanged. Data refresh removes retired member instances and synchronizes GPU ownership. Satellites and AIS vessels stay separate.
+
+### Regional news cards
+
+`news-region-cards.js` reuses `renderNewsCardContent` from `info-card.js` and the cruise adapter's news presentation mapping. Cruise and regional cards share the news template, 📰 icon and gold header. Regional metadata is reduced to source, category and time. Each card owns an independent cancellable `typewriter.js` instance, while an invisible sizing layer reserves the full summary height. Summaries are not truncated. A fixed content area with internal scrolling keeps new headlines and typing from changing placement. Automatic stowing pauses typing and rotation; expanding resumes, and the seven-second reading interval begins after typing completes.
+
+`news-region-model.js` owns four isolated queues and remaining reading time, using `CRUISE_CONFIG.dwellMs` (seven seconds). It supports per-card pause, navigation, hidden-page resume and current-ID preservation across refreshes. Existing `getCruiseNewsItems()` data updates through `earth:news-payload-updated`, retaining source/category/content-readiness filtering. No new collection requests or global/other-region backfill are introduced.
+
+News and compute submit scopes through `createCalloutGroups` to one `createSpatialCallouts` controller, sharing destination planning, drag locks, size changes and obstacle handling. Resize state is looked up by element identity; news layout keys use `news:<region>` to avoid compute-key collisions. Existing regional connector styling and routing remain unchanged, as do normal object-detail connectors.
+
+The opt-in switch persists under `planet.earth.news-region-cards.v1` and lives in the existing news panel. Mobile moves the same nodes into the news drawer and removes their map connectors. Destruction releases cards, animations, observers and subscriptions. Verification covers region isolation, pause/resume, current-story retention, scope removal, simultaneous 1080p layout, mobile and returning to desktop.
+
+The news cruise adapter completes `presentItem` only after typing finishes, so `CruiseSequencer` dwell never cuts off long text. The wait checks sequence ownership every frame and exits on manual interruption. Regional-news toggles reflect `aria-pressed` with a highlighted background and border. Compute headers retain country flags and use small representative emoji for regional groups.
+
+### Card DPI and frame-stage boundaries
+
+Compute, regional news and normal/cruise detail cards share `--hud-detail-card-width` and the same `info-panel.css` typography, metadata and summary rules. Compute cards, charts, icons, spacing and controls use root `--hud-scale`; manually resized inline pixel dimensions are normalized to a scale expression. SVG viewBox units scale with the chart viewport rather than receiving a second multiplier. Europe uses a small EU monogram with the title's font metrics, avoiding Windows flag-emoji fallback alignment.
+
+The configuration menu retains its independent 340px width and original height limit rather than inheriting detail-card geometry scaling. Compute headers keep the shared HUD specification; larger primary values, charts and content spacing support the common width. Regional motion is owned by the JS tween: CSS position transitions and forced transform compositing are removed. Final left/top values align to device pixels, including decorative float, and connectors use that same displayed position. Regional cards use peripheral stowing when full content does not fit.
+
+Global selections are heterogeneous: satellites are GeoJSON objects, cables are lines, and only surface interaction markers carry `userData.icon_layer_id`. `markerPresentationId` generates stack identity only for that marker contract, returning null for other selections instead of dereferencing missing fields during the frame loop.
+
+`frame-stages.js` isolates independent update stages so a failed card, label or layer cannot skip other stages and scene rendering. It reports the stage/error, retries at one-second intervals or immediately after selection changes, and resumes normally on success. Fixing the cause and observing no runtime errors in normal scenarios remain acceptance requirements; isolation does not replace the fix.
+
+All object-selection confirmations use `showSelectionStatus(name)` and “Selected: name”, including direct clicks, cluster children, search and motion confirmation. `confirmInteractionCandidate` and its feedback option are input-neutral. The cable layer updates selection/legend state while the interaction entry emits one notification. Obsolete lock/location/motion-confirmation message keys are removed; actual motion-mode changes and gesture guidance retain their mode label.
+
+### Detail-card information cleanup
+
+Normal details retain identity, business properties, timestamps and useful reliability context. Satellite cards omit the three rendering diagnostics (coverage capability, current presentation and coverage model) without changing coverage controls. News details omit feed identity, source type and fetch channel, retaining publisher, category, region, publication time and summary. Facility cards omit geocoding provenance, confidence scores, reasoning, matched names and verification timestamps while retaining location precision and verification status. Identical GPU model/platform values appear once. Internal source status is omitted; compute precision/measurement and original-source access remain.
+
+Collector cards omit the redundant activity summary while retaining observation counts, event times and coverage. BGP event confidence remains relevant to alert reliability. Cables omit a single-coordinate row and custom points omit internal record IDs. Empty vessel enrichment no longer displays a caching message or enrichment confidence scores; identity, navigation, available profile data and source attribution remain. Desktop and mobile share field definitions. Underlying data and location-correction operations remain intact.
+
+### Performance with multiple cards and the full satellite set
+
+Regional news and compute cards retain their shared dark surfaces, borders, shadows and text while avoiding per-card backdrop filtering of the changing WebGL/video scene and SVG edge distortion. `contain: layout style` limits layout propagation. Pixel-aligned positioning, card count, content, typing and float timing remain intact.
+
+Each `CalloutConnector` SVG covers its path plus node/shadow padding rather than the entire viewport; path coordinates remain in screen space. Geographic anchors cache unchanged local coordinates, invalidate on coordinate changes, and still update world projection and front/rear visibility each frame. Obstacle tests compare rectangle coordinates directly without allocating bounds for every candidate pair. HUD obstacle measurement precedes that frame's card-style writes.
+
+Satellite interpolation copies exact endpoint samples and retains radius-preserving interpolation between them. Trail compaction only adds an early rejection for high-altitude trails that already fail the existing error bound. Repeated identical hover/selection indices avoid full alpha-buffer rewrites. Static cable and landing-point local matrices are cached; landing-point scale changes explicitly rebuild their matrix while parent-world transforms propagate normally. No satellites, trail samples or rendering pixels are removed.
+
+For development diagnostics, append `?profileFrames=1` to the Earth URL. `data-earth-frame-profile` reports per-stage CPU mean, maximum and count every second; profiling is disabled normally. `data-earth-gpu-renderer` identifies the GPU. Performance evidence must include actual canvas pixel dimensions, fully visible card count, satellite visibility, zoom, video state and 30-second average FPS. Pending cards or smaller viewports do not establish a 1080p full-scene result. CPU stage durations are not GPU timings.
+
+## Detail-card images
+
+`card-images.js` integrates optional imagery into the existing `showInfoCard` path used by selection and cruise, with one presenter implementation for desktop and mobile. It requests `/api/v1/earth/card-images/resolve` on selection using NORAD IDs or source-qualified object IDs. The server derives models, groups and categories from current catalog data. A bounded 100-identity, 30-second cache avoids repeated lookups; a same-origin storage revision event refreshes open cards after an admin save. No image work runs in the animation loop.
+
+The shared `card-images.css` places imagery behind the rightmost 68% of the existing body. Horizontal and bottom gradients intersect using standard/WebKit mask composition. The image uses 0.85 opacity with `saturate(1.2) contrast(1.1)`; its containing layer fades to 1, without an additional dark scrim or group opacity reduction. Text, headers, DPI sizing, scrolling, dragging and connectors retain their own layout. Decode precedes the fade; reduced motion skips animation. Missing/broken images produce a data-only card. Selection tokens guard both resolution and decoding, so late results cannot replace newer selections or reopen a closed card. The header source link exposes attribution and license information.
+
+`card_image_configuration.py` stores assets and assignments in a separate system setting, using revision checks, row locks and audit transactions. Collected records are never edited. Resolution prefers object, model, group and category in that order; explicit per-object suppression stops fallback. Disabled assets cannot resolve; permission metadata remains truthful and separate from the enabled flag. Schemas reject duplicate targets and dangling references. Built-in assets come from the same manifest copied into the backend container, without seeding the database. Known built-in IDs preserve edits/removals while merging newly shipped entries; previous_defaults replaces old bundled URLs while preserving fields changed from the prior default and all custom image URLs.
+
+Pillow validates still JPEG/PNG/WebP uploads and generates 640/1280-bound WebP derivatives, preserving original files. Content-addressed files are written atomically and served through a read-only public endpoint; management, upload, catalog search and preview require administrators. See the operations runbook for storage/backup. The Frontier photo is facility-specific; Starlink remains a series illustration. Qianfan series imagery is enabled as requested, while its permission metadata remains unverified.
+
+Category `*` covers satellites, compute facilities, cables, landing stations, vessels, BGP incidents, BGP collectors and custom points, after specific category rules. Stable keys are MMSI, incident_key, collector_id and the custom-point ID. Missing identities in old snapshots allow only a type illustration. Rebind a collected object if its upstream source_id changes.
+
+
+### Five compute facility types and default imagery
+
+Supported types are `supercomputer`, `gpu_cluster`, `data_center`, `cloud_center` and `edge_node`. `compute-site-types.js` centralizes frontend titles, labels, counts and fallback; backend `compute_types.py` shares classification between GeoJSON and image lookup. An explicit supported metadata.site_type wins, followed by data_type and known source defaults. Unrecognized facilities use a generic data-center presentation instead of becoming GPU clusters. No facilities are fabricated or existing records reclassified by name.
+
+Each type supports legend filtering, marker icons, desktop/mobile details and image identity. New infrastructure cards use identity, operator, capacity, power and location fields without GPU counts or TOP500 ranks. The map accepts known sources or records declaring a supported compute type. Regional facilities retain snapshot/country constraints; infrastructure records do not require a GPU measurement contract and do not imply a global compute share. Built-in collectors remain TOP500 and Epoch AI; adding types does not create records.
+
+Seven user-supplied images provide defaults for the five facility types, BGP collectors and BGP events. All five categories are available in image management before data exists. Exact assignments retain priority. Manifest previous_defaults / previous_rules migrate old bundled sources and unchanged collector assignments while preserving custom crop, enabled state and specific bindings.
+
+
+### Frame-work reductions with unchanged presentation
+
+Cluster presentation reuses each parent's world matrix and local camera position within one update, refreshing on every frame. Fully collapsed members without child DOM still participate in hidden-state reconciliation, but skip invisible endpoint projections. Unchanged count and ARIA text no longer cause repeated DOM writes.
+
+Static point batches refresh on data, selection, filtering, distance scaling or explicit invalidation; selected overlays continue pulsing every frame. Parsed colors cache immutable strings/numbers only, never mutable caller-owned Color objects. Satellite dot/halo overlays update only the required ancestor transform rather than traversing all Earth descendants twice.
+
+Trail sampling combines the radius bound and initial error scan, preserving the existing threshold and subdivision indices. No satellites, trajectory samples, card content or resolution are removed. Deterministic comparison covered 10,000 histories with identical indices. Local Bun microbenchmarks (not whole-page FPS): 480 cluster members took about 1.19→0.90 ms collapsed and 4.47→2.86 ms expanded; scanning 16,621 trails took about 11.50→8.94 ms. End-to-end FPS requires a separate 30-second foreground comparison at identical resolution and scene/card/video settings.
+
+Regional news collapse buttons explicitly invoke the shared HUD controller. Their bodies use hud-panel__body--collapsible and aria-expanded follows the actual state. Only user clicks collapse cards; layout and performance code never hide their contents automatically.
+
+Floating object details and regional news share `--hud-detail-card-max-height`: 390px times HUD scale, capped at viewport height minus 24px. A min-height:0 flex chain keeps the header fixed and scrolls only the image-backed body. Short cards keep their natural height. BGP incidents prioritize type/severity/status/impact/time/summary; collectors prioritize identity/status/recent activity; facilities prioritize name/capacity/hardware, with location verification and provenance later. Desktop and mobile field order share CARD_CONFIG.
+
+
+### Detail identity and connector consistency
+
+BGP collector indexes use collector names. Shared marker indexes omit empty IDs and refuse cross-refresh replacement for ambiguous duplicates; a clicked marker still in the current layer retains its own reference. Stack presentation shares icon_item_id with the index. BGP incidents prefer incident_key, while raw anomalies use source plus ID to prevent numeric collisions across feeds.
+
+Satellite detail connectors identify the selected NORAD and relocate its index when the catalog array changes. Selection highlights rebind to that NORAD after refresh; a removed target clears selection. Uninitialized zero positions are not valid anchors. Cable anchors remain confined to the selected cable geometry, landing points use the clicked marker, and regional news/compute cards retain their regional anchors.
+
+
+When compute image configuration has no model/group rules, resolution uses a bounded fast path: the stable source prefix supplies the supercomputer/GPU category, then object and category rules are checked without scanning the collected catalog. Adding model or group rules automatically uses the full catalog resolver. Frontend identities, collected data and other object types are unchanged.

-# Intelligent Planet Interactable Clustering
+# Earth interactable clustering
 
-Earth interactable icons are managed by `createInteractableLayer`. Rendering still uses Three.js `Points`, and picking, hover, locked state, tooltips, and cruise focus still depend on marker `userData`; the clustering strategy only decides which markers are represented by a cluster dot.
+`interactable.js` owns fixed geographic membership, `cluster-motion.js` owns timed tweening, and `cluster-presentation.js` owns circular badges, projected children, picking and Spiderfy. Independent markers remain GPU Points. Each clustered child uses the same DOM icon throughout its animation and at the final position.
 
-## Strategies
+## Membership and zoom
 
-`cluster.strategy` supports three modes:
+Spherical buckets use real `icon_base_position` anchors. Defaults are distance 15 in Earth units, at least two members and at most 14 per group. Data, filter and visibility changes invalidate membership; rotation and zoom do not. Badges stay at the spherical centroid without screen avoidance.
 
-- `stable-spherical`: stable spherical clustering. It clusters by local 3D positions on the globe and caches topology by zoom band. Rotation and small zoom changes within the same band only update projection and size. Use it for semi-static layers such as BGP, compute centers, and Earth interactables.
-- `dynamic-screen`: dynamic screen-space clustering. This keeps the previous projection-based behavior and evaluates visible relationships per frame. Use it for high-frequency realtime layers such as vessels, or as a fallback.
-- `none`: no clustering. Every marker is shown independently. Use it for low-count layers or precision-first views.
+Use `cluster: { enabled: true }` or `cluster: false`. Options are `distance`, `minCount`, `maxMarkersPerDot`, `disableAboveZoom` (2.5) and `expansionHysteresis` (0.08). Zoom uses the UI's `globeZoomForDistance()` mapping: expand above 250%, collapse below 230%, and show no aggregate badges at 500%. Satellites and AIS vessels remain separate.
 
-`cluster: false` is equivalent to `strategy: "none"`. If a layer enables clustering without declaring a strategy, it keeps the compatible `dynamic-screen` behavior.
+## Motion and Spiderfy
 
-## Stable Spherical
+Both directions use a 320ms easeInOutCubic tween, complete after wheel input stops, and reverse continuously. Children interpolate directly from the centroid to their real local positions and retain the same DOM nodes at the endpoint. Because this chord can temporarily enter the sphere, occlusion uses a radial surface anchor while projection retains the interpolated position; intermediate frames remain visible.
 
-`stable-spherical` moves cluster identity from screen distance to globe distance:
+Only co-located or extremely close geographic anchors (about 0.00015 degrees) share a compact cross-layer stack. Screen overlap and coarse city buckets never merge different locations. Each icon retains its own real projection as its baseline, with the entire stack bounded to 24px per axis and small groups exposing approximately 8–12px edges. Stable IDs define resting order; selecting a rear item brings it forward, and clearing focus restores its slot. Ordinary expansion ends exactly at real projected positions; coordinates and marker positions remain unchanged.
 
-- Each marker uses `icon_base_position` as its geographic anchor.
-- By default, zoom levels above `2.5` force clustering off and show every marker as its original icon.
-- The current zoom maps to a discrete band; rotation and small zoom changes inside the same band do not recompute topology.
-- Clusters are recomputed only when the band, data revision, visibility, or filter state changes.
-- A cluster centroid is computed from member 3D positions and normalized back to the globe shell, so the cluster dot stays rigidly aligned to its geographic center.
-- Cluster dots do not participate in 2D avoidance, so screen-space repulsion cannot push them away from their real geographic projection.
-- Band changes use a small hysteresis margin so zooming at a boundary does not repeatedly bounce between two bands.
-- Newly created marker and cluster dots run a short scale + opacity ease. This is only a rendering transition; it does not change marker coordinates, picking objects, or locked state.
+## Interaction and BGP
 
-The stable strategy uses spherical bucket/hash neighbor lookup and must not use an all-pairs loop. Most frames only pay projection and material-size cost; topology cost is paid only on band or data changes.
+Clicking a badge expands it and pauses rotation. Legs have 14px transparent hit areas; hover highlights the matching leg and child, and either click selects the same business object. The canvas container accepts wheel input over the canvas and projected markers while excluding HUD scrolling.
 
-## Configuration
+Projected textures bake the original category tint. BGP events retain severity colors. Badges containing BGP and expanded BGP event children use an expanding/fading halo based on `BGP_CONFIG.ring`; replaced GPU effects are hidden to avoid duplicate rings at old anchors. Reduced-motion preference disables the pulse.
 
-```js
-const computeCenterIconLayer = createInteractableLayer({
-  id: "computeCenters",
-  // ...
-  avoidance: SURFACE_AVOIDANCE_PROFILES.city,
-  cluster: {
-    strategy: "stable-spherical",
-    minCount: 2,
-    maxMarkersPerDot: 14,
-    transitionMs: 220,
-    bandHysteresis: 0.08,
-    disableAboveZoom: 2.5,
-    bands: [
-      { key: "far", maxZoom: 1.7, distance: 15 },
-      { key: "mid", maxZoom: 2.6, distance: 8 },
-      { key: "near", maxZoom: 3.5, distance: 4 },
-      { key: "detail", maxZoom: Infinity, distance: 0 },
-    ],
-  },
-});
-```
+## Removed paths
 
-Realtime layers can stay dynamic:
+The low-zoom compact-dot desktop/mobile controls, persistence field, textures, rendering/picking branches and translations are removed. Dynamic screen clustering, discrete zoom bands, GPU aggregate dots and the old creation-time fade/scale transition are also removed. There is no legacy strategy fallback.
 
-```js
-const vesselIconLayer = createInteractableLayer({
-  id: "vessels",
-  // ...
-  cluster: {
-    strategy: "dynamic-screen",
-    enabled: true,
-    maxMarkersPerDot: 10,
-  },
-});
-```
+## Regression coverage
 
-## Tuning
+Tests cover 320ms completion, reversal continuity, visible intermediate frames, retained endpoint nodes, 500% expansion, immutable source coordinates, filtering cleanup, wheel target routing, linked leg hover/click and projected BGP category colors: `cluster-motion.test.js`, `cluster-presentation.test.js`, `globe-navigation.test.js`, `marker-badges.test.js`.
 
-- `distance` is the 3D globe-distance threshold and uses the same unit as `CONFIG.earthRadius`. Larger values cluster more aggressively.
-- The farthest band usually uses a larger `distance`; the nearest detail band usually uses `0` to split clusters into original icons.
-- `bandHysteresis` controls band-boundary stickiness. Too little can flicker near thresholds; too much can make band changes feel late.
-- `transitionMs` controls cluster split/merge easing. Keep it around 160-260ms; longer durations can make realtime layers feel sluggish.
-- `disableAboveZoom` controls the precision-view threshold. It defaults to `2.5`; above that zoom, no cluster dots are generated. Set it to `false` to disable the hard threshold.
-- High-frequency realtime layers should prefer `dynamic-screen` so frequent data changes do not trigger stable topology recomputation.
-- If a layer behaves poorly, switch it back to `dynamic-screen` or use `cluster: false`.
+## Refresh and first-frame preparation
 
-## Acceptance Checks
+A reused cluster ID does not imply reused Object3D instances: stale children are reconciled against current instances. Ownership changes immediately rebuild the GPU batch, and topology invalidation clears its old signature.
 
-- Rotating the globe inside one zoom band should not cause clusters to flicker or regroup.
-- Cluster dots should stay aligned with the globe-surface centroid and should not be pushed by avoidance.
-- Zooming into the detail band should restore the layer's original icon textures and click behavior.
-- Zoom levels above 250% should not show cluster dots.
-- Realtime layers such as vessels should reflect incoming updates immediately.
+Expansion prepares visible icons and waits for image decoding before starting its 320ms clock. Encoded URLs are reused per texture, and invisible rear members are not instantiated. Regression tests cover repeated refresh/zoom, preparation slower than the tween duration, selection/restoration and connector anchors.

Drawing no longer writes depth; original Line pick objects, cable IDs and state logic remain intact.
+- Landing points use the 128×128 monochrome `marker-landing-point.svg` micro-core instead of a glossy procedural ball; Sprite picking and billboard size logic remain intact.
+- Compute markers use canonical SVG inner glyphs over shared gradient plates, pale rims, top highlights and shadows. GPU/AI uses purple stacked layers, supercomputers purple chips, and infrastructure teal server racks. Estimated badges and picking remain intact.
+- Satellites share vivid real-inclination category colors with the legend and predicted orbits. Normal markers are prototype hard discs without outlines or sphere shading; breathing defaults off. Coverage stays blue and sunlight only affects opacity.

+| Supercomputer | Same purple family | Chip |
+| Cable landing point | Amber `#f59e0b`, pale-gold `#fef3c7` rim | Glowing circular core |
+| BGP collector | Blue and existing activity heat colors | Rounded badge containing the broadcast-tower glyph |
+| BGP event | Low/medium/high/critical: blue/amber/orange/red | Irregular flat event symbols, no badge plate |
+| Vessel | Cargo blue, tanker orange, passenger teal, fishing amber, military indigo, other silver | Heading arrow; anchored state retained |
+| Custom marker | Place green, note yellow, alert red, default blue | Pin, note sheet, warning triangle |
+
+BGP change events retain irregular flat symbols as the exception; collectors use rounded badges; other finite surface objects share cached badge textures without a new DOM node or draw object per marker. Vessels retain heading buckets and vertex colors rather than multiplying buckets by vessel type. Satellites use distinct category colors and hard discs without an outline; orbit and footprint calculations stay intact. The low-zoom dot control, persisted field and rendering/picking branches are removed.
+
+
+### Stable satellite palette
+
+Category colors follow [satellitemap.space](https://satellitemap.space/) while retaining this project's real inclination classes: 0–30° blue `#3399ff`, 30–60° orange `#ff801a`, 60–90° green `#00e680`, 90–120° purple `#cc33ff`, 120–180° rose `#ff3366`, unknown gray `#94a3b8`. A satellite keeps its hue across day/night; predicted orbits no longer use an unrelated yellow-purple gradient.
+
+All coverage uses `#3399ff`, opacity 0.34 and day-side opacity multiplier 1.65. Normal points have no dark outline; one `PointsMaterial` batch uses alphaTest=0.5. `satellitePixelSize()` smoothly varies visual size from 2.4 to 8.0.
+
+### Selected orbit and panel outlines
+
+Prediction covers the full period without truncating or fading the endpoints and without an appended closing vertex. Highlights travel forward along cumulative arc length in the same Line draw. TV and shared HUD shells use square corners, including the player clip, without changing panel size or dragging. Temporary frame-statistics instrumentation and its QA-only DOM attributes are removed from release code.
+
+### Landing points, limb badges and subtle sky brightness
+
+Cables and landing points share R+0.48 and renderOrder=1. `cable-surface.js` generates both on the actual surface triangles, removing ideal-sphere versus surface endpoint parallax. Normal points are yellow discs with a pale ring and no persistent halo. Only related points get a subtle pulsing halo in the existing batch shader; unrelated points dim, and deselection restores the normal yellow state.
+
+Rounded badges use anchor occlusion through `surface-marker-occlusion.js`: the GPU keeps a visible anchor's whole badge and hides it when Earth occludes the anchor. Screen-space picking shares the same check. Only badge layers replace per-pixel depth clipping; BGP change events keep their flat symbols and existing depth behavior. Collectors retain activity colors inside rounded plates. Normal, hover, locked and cluster badges share the path.
+
+Only the sky texture material receives `CELESTIAL_CONFIG.skyBrightness = 1.0`; Earth exposure, celestial lighting and business-layer brightness stay unchanged.
+
+Vessels are independent moving objects: their pre-badge heading arrows, anchored dots and hover/selected glow are restored. They do not use the fixed-facility rounded plates or whole-badge occlusion path.
+
+Normal and related landing points retain the same orange core and yellow rim. Related state adds a wider soft pulsing halo without changing core color, opacity or size. Deselecting clears the halo; unrelated points retain the dim state.
+
+
+### Sky color output
+
+The star map is decoded as sRGB. `celestial.js` uses shared `preserveTextureOutput()` to encode only the sky material back to display sRGB. The Three.js r128 renderer retains its existing global linear output so Earth, satellites and other layers remain unchanged. `skyBrightness=1.0` retains source brightness; missing output encoding displays decoded dark values directly and cannot be corrected by raising the multiplier alone. Validate with the same map, camera and orientation, comparing rendered pixels and the 1.0/1.5 response instead of checking asset loading only.
+
+Satellite hover rings use the hovered satellite inclination category color, matching the point and legend. Changing the hovered object resolves its color again; position updates preserve it.
+
+All map cards use the root HUD DPI scale. Regional and cruise news share header icon, colors, typography and padding; the regional variant only simplifies metadata and adds independent rotation controls. Compute metrics, trend charts and title icons no longer use unscaled fixed pixels. Europe uses a compact EU monogram; other region emoji follow the same scale.
+
+Compute markers use five canonical SVGs: compute-supercomputer.svg, compute-gpu-cluster.svg, compute-hdd-network.svg, compute-cloud.svg and compute-edge.svg. They retain the compute layer purple badge and existing selection behavior.

 # Earth Render Layer Order
 
-The compute topic reuses the compute-center Interactable icons, depth behavior, and layer order. Country/year changes replace that layer's data and clear prior selection. Its HUD is screen UI excluded from Earth picking in `main.js`. Regional cards are tethered in screen space; rear anchors do not draw connectors through the globe. Facility details reuse the existing card and mobile details drawer. The existing outer atmosphere shell remains, while the starfield is restored to commit `83a10a6c` (`brightStarOpacity:0.88`; no tint/brightness calibration). The HD overlay is a white `MeshBasicMaterial` with opacity 1 and `toneMapped:false`; `texture-colors.js` selects the r128 `encoding`/`LinearTosRGB` path or r160 `colorSpace`/colorspace fragment. No Phong white light, colored twilight, blue night tint, camera boost, or shoulder curve is added. No new post-processing, GPU draw pass, or high-resolution texture was added; the compute topic adds 45 local SVG flag assets.

Its HUD is screen UI excluded from Earth picking in `main.js`. Regional cards are tethered in screen space; rear anchors do not draw connectors through the globe. Facility details reuse the existing card and mobile details drawer. The visible HD surface uses a single-draw ShaderMaterial in `earth-surface-material.js`, retaining the R+0.48 mesh, depth policy and surface pick target. The existing controller still switches all four 8K maps, updates the sampler and disposes the previous texture only after success. Normals, view direction and astronomical sunlight share world coordinates. Land is matte; water has grazing-angle cool reflection without a white specular lobe. The existing geographic land/ocean texture owns the optical mask independently of border visibility, with a conservative chroma fallback until loaded and reflection suppression over ice. Original JPEGs are neither repainted nor downsampled. Color textures are tagged sRGB with mipmaps. The r128 surface shader decodes sRGB; r160 uses hardware texture decoding. Both combine light in linear space and encode once. A local filmic curve affects only the surface instead of enabling global ACES exposure on the sky and data layers. The terminator spans normal dot products [-0.12, 0.28]; night attenuation retains 0.12–0.32 linear illumination after tone mapping to avoid crushing source shadows twice. One R×1.025 BackSide/Additive shell replaces the three rim shells, with depthWrite=false and depthTest=true; inner scattering is part of the surface pass. Independently switchable clouds use matte day/night shading at renderOrder 1.1. The sky uses the existing `starmap_deep_8k.jpg` without a tint overlay.

 ## Full-set rendering and updates
 
 - Batching changes GPU submission, not the number of satellites, cable segments, or landing points. It does not filter data by the visible hemisphere. Every adjacent cable vertex pair remains present, and picking still returns the original business object.
-- Satellite foreground and backdrop remain two `Points` draws. Vertex shaders compute breathing from static per-point parameters and a shared frame-time uniform; existing hover/locked state still controls point masking.
+- Normal satellites use one hard-disc `Points` batch without a backdrop batch. Optional breathing remains in the vertex shader, defaulting off; category filters and hover/locked masking share the same visibility state.
 - `satellite-position-worker.js` uses the same Three.js / SGP4 versions as the main thread. `satellite-propagation.js` owns shared orbit, display-altitude, and fallback calculations. Full positions and initial trail samples use transferable arrays; only one calculation is in flight. Reload, clear, and altitude-mode changes terminate the previous Worker.
 - Worker startup failure or `SATELLITE_CONFIG.workerStartupTimeoutMs` expiry falls back to the shared synchronous calculation. Counts, APIs, the existing update interval, and trail length are unchanged.
 - Verify full draw ranges, per-item picking, locked overlays, trails, rear-side occlusion, visibility toggles, and resource release after clearing. Frame-time comparisons require identical data, view, and resolution.

 ### Startup loading versus drawing order
 
 The selected full-resolution surface loads before independent data requests; boundary construction no longer blocks its first frame. This does not change renderOrder, depth behavior, geometry precision or image resolution. Data refresh retains the surface, with texture disposal limited to successful replacement or scene teardown.
+
+### Loading-state boundary diamond regression
+
+`v0.58.0` moved land fill to R+0.32 and HD imagery to R+0.48, but left the tint placeholder at R+0.04 with a 64×32 mesh. Its chords intersected the 128×128 base, producing latitude-ring diamonds until loaded imagery covered them. The old geometry penetrated the base by approximately 0.153 at tested samples.
+
+Base, tint, land fill and HD surface now use `createEarthSurfaceGeometry()` and one UV triangulation. Tint and land share R+0.32; neither writes depth, so their existing renderOrder lets loaded fill replace the tint. HD remains R+0.48. Occluder, terrain, clouds, picking and geographic display policy are unchanged. Do not mask intersecting geometry by changing renderOrder alone, disabling depth tests or hiding the loading globe.
+
+`earth-surface.test.js` ray-tests the actual loading tint and verifies at least two 24-bit depth steps of separation at 50%, 100% and 500%. Browser checks cover delayed textures, boundary toggles, rotation/zoom, and land/HD completion.
+
+### Surface marker alignment and limb visibility
+
+Cables and landing points share R+0.48, the `earthSurfacePoint` triangle projection and renderOrder=1. Related landing halos use an emphasis attribute in the existing batch, adding no Sprite or draw call. Rounded badges use GPU anchor ray/sphere occlusion: draw the entire billboard when its anchor is visible, otherwise clip it entirely. CPU picking uses the same test to reject rear anchors. Only `icon.badge` layers (including compute and collectors; vessels independently use heading arrows) use this path. The selected BGP event's static overlay halo uses the event icon's R+0.48 anchor, foreground order and whole-anchor front/rear visibility; the existing animated BGP event ring remains a separate effect with its original behavior.
+
+
+The `.map-clusters` projection layer uses z-index 8 below HUD and whole-marker occlusion from real surface anchors. Ordinary points retain their Three.js layers; transitioning members render only once in the projection layer. Spider legs use widened transparent hit areas; hover highlights the matching line and child, and both clicks resolve the same business object. Wheel input over projected markers and legs continues to zoom the globe.
+
+Co-located markers share a compact projection stack across categories; screen collisions never merge different locations. A selected child uses projection `z-index: 1000`, while the locked overlay for an unclustered marker uses the shared foreground `renderOrder >= 100`, so focus stays on top across layers; clearing focus restores stable ID order. The aggregate badge stays below a selected child during its opening tween. `icon_presentation_screen` lets detail connectors follow display offsets while markers retain their real anchors. Ownership changes immediately rebuild the corresponding GPU batch.
+
+Regional news and compute cards share the `#earth-region-callouts` spatial root (z-index 48), with independent data and reading state. News connectors use representative regional anchors, unchanged by story rotation. One controller excludes all owned cards when measuring HUD obstacles and tracks size changes by element. Mobile news cards live in the drawer without map connectors.

+
+Each card rotates only displayable stories from its own region after its typewriter summary finishes and a seven-second reading interval elapses. Hovering, keyboard interaction, dragging or collapsing pauses that card while other regions continue. Controls provide previous/next, pause/resume and a source link. Refresh preserves the current story where possible. Empty regions stay empty instead of borrowing unrelated stories.
+
+Cards reuse the cruise-news gold header and 📰 icon, preserve full summaries and simplify source metadata, with the compute cards' dragging, collapsing and automatic placement. News and compute cards share one placement plan. Connectors identify representative regional anchors, not precise event locations. On mobile, enable “Region cards” from the news page and read them in the drawer.

 ## Compute intelligence
 
+Administrators maintain card data in **Earth content → Compute comparison**. Add a report title, URL, publisher, report year and page/figure locator under Sources, then add country values by observation year, metric and source under Observations. Save and publish applies the complete configuration. Global shares use the world denominator; absolute values use FP32 EFlop/s. Bilateral shares are derived from same-year US and China observations, and regions require every member. Do not mix FP16/FP64 capacity, regional estimates or facility counts. Omit missing countries; enter zero only when the source explicitly reports zero.
+
+Innovation gap observations remain independent US-minus-China values. Referenced reports cannot be removed until their observations are removed or reassigned. Duplicate metric/year rows, missing sources and global shares totaling over 100% are rejected. Concurrent edits return a conflict while preserving the local draft. Restore defaults requires confirmation and restores the bundled report data. Publishing and restoring are audited. Same-origin Earth pages receive a refresh notification; other visible pages check once per minute and hidden pages check when visible again. Reports must still be reviewed manually; configuring a URL does not scrape a report.
+
 Open the analysis icon beside Compute Centers, then enable Show region cards. Connectors draw to their target positions before the cards fade in; subsequent globe motion does not replay entrance. Closing the configuration window or pressing Escape leaves the cards enabled; the analysis icon reopens configuration, while the switch disables the cards. Anchors rotate with Earth while cards remain readable. Dragging or expanding grants reading time; after a substantial change in geographic direction, cards can move together when that materially reduces crossing or detours. Active interaction prevents movement, while manual positions remain preferences rather than permanent pins. Rear regions retain their state without a connector drawn through the globe. Existing layer, news, and media windows remain available.
 
 The picker groups the canonical comparison catalog as China, US, Europe, APAC excluding China, and Other; the groups are display buckets, not statistical denominators. It offers period and metric selection. Bilateral share still uses US + China as its fixed denominator; unavailable measures stay missing for other participants. Regional anchors are label positions, never facility locations. Source buttons open report evidence and facility buttons reuse the existing detail card. Mobile uses a compact regional overview in the drawer. Each row is an accordion: tapping the same header collapses it, tapping another collapses the old row, and at most one long card is open. The expanded card keeps trends, region members, facilities, media, and sources; there is no region subpage. Settings remain a separate on-demand page.
 
-The default national metric is global compute-device scale, covering basic, intelligent, and supercomputer capacity with observations from 2020–2023. The reviewed absolute observations are 302 for 2022 (`caict2023` evidence) and 435 for 2023 (`caict2024` evidence). Japan's global-share observations are 6%/5%/4%/4% for 2020/2021/2022/2023. Product groups APAC and OTHER do not mean the report's Japan or “other” categories, and EUROPE remains missing until its membership matches the report. Bilateral share always uses US + China as its denominator. A missing primary value may show the latest reported year (currently 2023); explicitly selecting 2026 still shows missing and does not backfill. Unconfirmed comparability does not produce year-over-year change. National report metrics remain separate from public facility samples; coverage counts remain auxiliary evidence, never computed capacity or a global coverage rate. TOP500 and Epoch may overlap, so source-record counts are not a global census. API review metadata is `reviewed_at=2026-09-22` with the matching version date. An independent Epoch share mode is not implemented.

-This prototype shows up to six content cards. The main card centers on the selected compute metric: a large share percentage or absolute value with its unit, observation year, historical context, and source entry. Missing comparable data is shown as “No comparable data yet”; a trend is omitted when there are no observations rather than rendered as an empty chart. Facility records and coverage metadata remain complete but move to the expanded auxiliary area; sample counts are evidence context, never a compute value or global coverage rate. Region previews may show member counts, and long lists open only when needed. Desktop compact cards are about 268px wide with content-driven height; expanded cards support user resizing up to 480px. Mobile keeps the same single metric meaning in the one-card accordion rather than promoting facility counts. Local card position and size are saved, with a reset-to-auto action. The content layout leaves room for later image and video integration, but those media data are not connected yet. When outside space is insufficient, cards can travel through the globe's foreground instead of teleporting or shrinking to labels.
+Select up to six compute participants sharing peripheral space with four regional news cards. Full cards use the same DPI-scaled 340px base width and retain business metrics, years, trends and sources; missing values remain explicit. Cards stay near screen edges while globe rotation moves only connectors. When space is limited, full cards remain visible with some peripheral overlap. On release, valid drops retain the new position. Out-of-bounds or central drops settle nearby, without returning to the pre-drag slot. Peripheral overlap is allowed. Cards have no manual reset action; positions and sizes remain persistent. News rotation and typing do not repeatedly push neighboring cards; long content scrolls internally.
 
 When the map cards switch is off, the overview summary still loads. Turning it on shares the map loading event; a newer request cancels the previous one. Drawer event handling follows `composedPath()` so replacing inner HTML cannot accidentally collapse the active row. The shared HUD collapsible panel animation is reused and respects reduced-motion preferences. Facility names remain in a scroll region capped at 240px; rows are left-aligned, wrap long names, and retain at least 42px of touch height.
+
+## Surface and object appearance
+
+The real surface retains all four map choices. Day/night shading follows the sun, with uniform illumination when disabled. Selected cables show traveling pulses and landing points use amber micro-markers. Facilities retain category symbols, with numbered solid circles for aggregates. Satellites retain self-glow/ground-coverage modes, trails and their existing orbital motion. BGP severity, vessel heading, related highlights, detail cards and mobile drawers retain their established interactions.
+
+### Satellite orbits and collection attempts
+
+Selecting a satellite shows an open predicted arc with highlights moving in the travel direction. Satellites, trails and footprints remain synchronized. Coverage stays blue across day/night; particle and orbit category colors match the legend. Dragging continues outside the globe silhouette, with reduced sensitivity at extreme zoom. The TV panel has square corners like other cards.
+
+Retriggering a datasource creates a new task while older failures remain in the failed group. Task Status uses a checklist icon, distinct from Refresh. CelesTrak can reuse valid recent download cache; each new collection attempt still gets its own task and updates collected data.
+
+
+Display → Satellites → Close-up labels defaults on; turning it off hides satellite map names while retaining detail cards. The zoom-threshold slider below the switch ranges from 250% to 500% (default 400%); labels appear at or above the selected zoom and hide below it. The count slider sets a saved limit of 5–36 labels (default 36); occlusion or limited space may result in fewer visible labels. Sky brightness ranges from 0–200%, defaulting to 100%. Both choices persist. Compute region cards wait for drag/globe motion and new-card placement to settle before necessary avoidance. Otherwise they float subtly around stable positions and pause during interaction. Compute legend category counts describe currently located markers.
+
+
+Surface aggregates appear as solid numbered circles. Click to expand members; only co-located or extremely close geographic markers form compact stacks at their location, with exposed clickable edges. Ordinary markers stay at their real projected positions. Selecting a rear icon brings it forward and opens its details; clearing focus restores its original position. Ordinary groups split above 250%; no aggregate badge remains at 500%, and co-located markers expand directly.
+
+Object detail cards show identity, business properties and update times without rendering diagnostics, collection channels or coordinate-matching internals. Facility location precision and verification status, BGP alert confidence, and news publisher, publication time and summary remain visible.
+
+Detail popups share the news-card height cap. Headers remain fixed while long bodies scroll; key event information and device specifications precede location verification, provenance and related objects.
+
+### Detail-card images
+
+Open Earth Content → Layer resources → Detail card images. Upload a still JPEG, PNG or WebP, or enter an image URL. Set its title, source, credit, license and crop focus; the preview uses the actual feathered card background.
+
+In Assignments, select satellites, compute facilities, cables, landing stations, vessels, BGP incidents, BGP collectors and custom points, then an object/model/group/category. Search selects current catalog objects and stable identifiers; missing model data does not produce invented choices. Apply an assignment to the draft, then Save to publish. Object rules take precedence over model, group and category rules. “No image for this object” suppresses all fallback images for that object.
+
+Verify an object to see its draft match before publishing. Disabled assignments allow more general rules to match. Remove assignments before deleting an image. Conflicting saves preserve your draft.
+
+Earth fades available imagery behind the existing detail data. Missing or failed images leave a complete data-only card. The header image icon links to the source and exposes attribution/license in its tooltip. Every map object type has a bundled default: exact and series images take precedence over explicitly labeled type illustrations. Starlink, BeiDou-3 and Qianfan are assigned; Qianfan retains its unverified permission metadata. Fresh installs need no setup. Upgrades merge missing defaults after services restart while preserving custom assignments and explicit suppression.
+
+Compute legends and details support supercomputers, GPU clusters, data centers, cloud computing centers and edge nodes. Manage their defaults under Compute facilities → Category in image management. Types without collected records show a zero count. BGP collectors and incidents have separate default imagery.

 # `planet.sh` Startup Performance Optimization
 
-## Background
+## Windows desktop launcher
+
+The launcher prefers a new Windows Terminal window and explicitly runs PowerShell 7 (`pwsh.exe`), independently of the default Terminal profile. Without PowerShell 7 it falls back to Windows PowerShell; without Terminal it starts the available PowerShell directly. The CMD bootstrap also prefers PowerShell 7. Ordinary entries request elevation; entries already running as administrator still dispatch to the preferred terminal without another elevation request. The child validates its privileges and enters WSL directly, preventing recursive windows. The existing post-restart WSL shell is retained.
+
+On first use, open the actual project folder in Windows Explorer and double-click the repository's `planet.cmd`. It derives the WSL distribution and Linux project directory from its own location, creates `Planet.cmd` on the current user's actual Windows desktop, then follows the normal restart flow. Both `\\wsl$\distribution\...` and `\\wsl.localhost\distribution\...` work. Local Windows-drive checkouts use the default WSL distribution and `wslpath`. Windows resolves the desktop location, including redirected desktops such as OneDrive; WSL, zsh and project dependencies must already be installed.
+
+Subsequent desktop launches use the bound target, request the existing administrator elevation and call `planet.sh restart --allow-lan`. No test ports are embedded: defaults remain frontend 3000, backend 8000 and AI Provider 8010, subject to explicit `DEFAULT_*_PORT` environment overrides. Successful restarts open Earth using the actual `ports.env` values and retain the WSL shell; failures display their error without opening a success page. `scripts/windows/planet-launcher.ps1` owns path resolution, desktop installation and elevation; `scripts/windows/restart.zsh` only bridges to the existing lifecycle script.
+
+Use `planet.cmd --install-only` on Windows to generate or validate a launcher without restarting services. Re-running the repository entry updates the same target's launcher. Other projects and unmanaged files are preserved by choosing a target-specific filename. After moving a checkout, regenerate from its new location; old launchers never guess another directory. Desktop launchers require the scripts in the checkout and are not standalone installation packages.
+
+Do not copy the raw repository `planet.cmd` to the desktop by itself: first installation needs the adjacent `scripts/windows/` directory. On another computer, generate a new launcher from that computer's checkout instead of reusing an old desktop copy. Server paths such as `/home/linkong/planet` and personal workstation paths both work without machine-specific Git edits. Run under the Windows account that owns the WSL distribution; elevating under a different account may expose a different set of registered distributions. Installation itself does not require administrator privileges; elevation is requested for the actual restart.
+
+Run Windows regression checks with `powershell.exe -NoProfile -ExecutionPolicy Bypass -File scripts\harness\test_windows_launcher.ps1`. They cover target resolution, special characters, generated launchers and name collisions. `scripts/harness/test_windows_restart.py` uses disposable command substitutes to check restart arguments, browser opening after success and shell retention after failure. The latter runs in quick-check without starting real services.
+
+## Startup background
 
 Use `zsh ./planet.sh start --non-motion-agent` for daily startup; use `init` when preparing a new environment. When investigating latency, distinguish initial dependency downloads, container readiness, and application initialization using the stage timestamps.

-昼夜明暗使用以太阳地平线为中心的窄平滑过渡（法线点积 ±0.12）。日面保持原图亮度上限；夜面线性光照系数为 0.24，原图暗部最高保留 0.60，按源亮度连续过渡，以保持暗色海洋和森林细节。只使用中性标量，不增加曝光、彩色罩层、额外渲染通道或纹理。
 
 地表底图与新闻频道复用 `hud-select-menu.js` 的 HUD 浮层、列表、选中标记、键盘导航和定位；`tv-source-menu.js` 仅保留频道文案适配。底图关闭搜索、分页和计数，菜单通过触发按钮归属参与移动抽屉的内部点击判断。
 本文件描述当前智能星球前端的真实结构，重点是帮助后续继续改 HUD、图层、媒体面板、真实地形、BGP 可视化时，不再重复踩结构和状态同步上的坑。

+星空贴图按 sRGB 解码；`celestial.js` 通过共享 `preserveTextureOutput()` 仅为星空材质补齐屏幕 sRGB 输出。Three.js r128 的全局 renderer 仍保持既有线性输出，避免改变地球、卫星及其他图层。`skyBrightness=1.0` 表示原图亮度；缺少输出编码时，解码后的暗部会再次以线性数值显示，不能靠提高倍率修正。验证应固定星图、相机与视角，对比渲染像素和 1.0/1.5 两档响应，不能只检查加载成功。
+
+
+### 图例直接筛选
+
+当前交互物件继续决定图例类型；通过现有开关启用图层也会切换到对应图例，不增加筛选入口。海缆按线路名称、算力按类型、船只按船型及停泊状态、BGP 按事件级别和观测站活跃度筛选；覆盖范围和影响区域各自控制对应效果。国界图例分别控制线条、陆地填色与海洋填色，海陆 mask 数据本身不变。已不存在的 BGP“事件连线 / 枢纽”行被移除。
+
+`legend-filters.js` 保存各类独立的页面内筛选状态；`legend.js` 统一绘制带 `aria-pressed` 的图例按钮，桌面和移动端共享同一状态，刷新图例保留键盘焦点。`interactable.js` 在绘制批次、聚类候选及拾取前应用筛选，保留完整原始数据、统计总量和对象身份。实时船只类型变化、数据重载及图层开关不会绕过筛选；隐藏选中项清除卡片和覆盖，显式搜索选中隐藏项则重新显示相应类别。船只轨迹请求使用版本检查，避免隐藏后迟到响应恢复旧轨迹。
+
+### 稳定卡片与显示偏好
+
+`callout-rest.js` 保留 450ms 的动作稳定门槛与最多 1.5px 的轻微漂浮。鼠标悬停、键盘阅读、拖拽与 reduced-motion 暂停漂浮；装饰偏移不参与持久化和布局求解，中央边界始终受保护。
+
+显示设置新增 `shared.satelliteLabelsEnabled`（默认 true）以及 `shared.satelliteLabelMinZoom`（2.5–5，默认 4）与 `shared.skyBrightness`（0–2，默认 1）。桌面与移动控件、刷新、重置共用同一运行时状态。星空倍率在线性空间作用于星空材质，沿用局部 sRGB 输出，不修改地球曝光。算力图例显示实际已定位分类数量，芯片与堆叠 SVG 继续按 `site_type` 区分；数据集中只有 GPU 时不伪造其他类型或坐标。
+
+所有目标位置与合法路径先确定再提交。`callout-dock-motion.js` 使用 240–420ms 时间补间，`callout-routing.js` 只提供静态避障路径。暂停保留进度与终点。布局与移动不改变卡片的展开状态；没有完整卡片通路时直接使用最终落点，不临时折叠。旧的循环评分、分阶段让位、中心区域兜底和途中坐标固化路径已移除。
+
+
+### 聚合圆标与 Spiderfy
+
+普通地表标记继续由 `interactable.js` 批量绘制；聚合组使用 `cluster-presentation.js` 的同一组投影节点贯穿合并、展开和展开后停留。圆标为 26px 实心渐变圆，显示真实成员数，混合类别带琥珀外圈。分组只随数据或筛选更新，缩放过程中不反复拆成中间子簇。
+
+`cluster-motion.js` 用固定 320ms 三次缓动控制进度。可见图标准备和解码完成后才开始计时，纹理编码按缓存复用；子点从组中心补间到真实标记投影，最终显示偏移由 `marker-stack.js` 统一计算。动画与终点保持同一个 DOM 节点，反向切换从当前进度续接。
+
+聚合判定使用界面的 `globeZoomForDistance()`；超过 250% 展开，缩回阈值有滞后，因此 500% 不显示聚合圆标。只有同坐标或极近地理锚点（约 0.00015°）跨图层紧凑堆叠；屏幕重叠和城市粗网格不会把不同地点合并。每个图标以自己的真实投影为基准，整叠在每个轴向最多错开 24px，小组露出约 8–12px 点击边缘。稳定 ID 决定初始顺序，选中后排对象时移到前端；聚合子点使用 `z-index: 1000`，未聚合图标使用共享的锁定覆盖层 `renderOrder >= 100`，跨图层重叠时仍由焦点对象在最上面，取消焦点后恢复原顺序。普通点展开终点严格等于真实投影，堆叠不改变经纬度或 marker 位置。数据刷新按实际成员实例清除旧节点，并同步重绘 GPU 隐藏批次；卫星与 AIS 船只不接入。
+
+### 区域新闻卡片
+
+`news-region-cards.js` 复用 `info-card.js` 的 `renderNewsCardContent` 与 `news-cruise-adapter.js` 的新闻展示映射。巡航与区域卡片共用新闻内容模板和 📰 图标、金色标题栏；区域卡片精简为来源/类型/时间三项元信息。`typewriter.js` 为每张卡片提供独立、可取消的打字机实例，先用隐藏排版层预留完整摘要高度，避免打字时卡片持续变高。摘要不截断；新闻卡片预留固定内容高度，长内容内部滚动，换标题和打字不改变落位。手动折叠时暂停打字及轮播；展开后继续，完整打完后再开始 7 秒阅读计时。
+
+`news-region-model.js` 维护四个互相隔离的队列与剩余阅读时间，使用 `CRUISE_CONFIG.dwellMs`（7 秒），支持单卡暂停、手动翻页、页面隐藏恢复和数据刷新保留当前 ID。数据来自已有 `getCruiseNewsItems()`，随 `earth:news-payload-updated` 更新，沿用来源、类别和可展示内容过滤；不新增采集请求，不将 global 或其他区域补入空队列。
+
+新闻与算力通过 `createCalloutGroups` 向同一个 `createSpatialCallouts` 提交卡片，统一求解目标位置、拖拽锁定、尺寸变化和遮挡。尺寸观察以元素身份查找状态，不依赖地区字符串；新闻布局键为 `news:<region>`，避免与算力地区冲突。仍使用既有区域卡片连线，不改变普通点击详情的连线方式。
+
+启用开关保存在 `planet.earth.news-region-cards.v1`，默认关闭，入口位于现有新闻面板。手机将相同节点放入新闻抽屉并退出地图连线布局。销毁时释放卡片、动画、尺寸/布局观察与事件订阅。验证覆盖队列隔离、暂停与继续、刷新保留条目、共享布局增删、1080p 同时显示、移动布局和切回桌面。
+
+新闻巡航适配器在正文打字完成后才结束 `presentItem`，因此 `CruiseSequencer` 的停留计时不会截断长文。等待每帧检查当前序列，手动切换或退出可立即中断。新闻区域开关使用 `aria-pressed` 同步高亮背景与边框；算力区域标题保留国旗，区域组合使用小尺寸代表 emoji。
+
+### 卡片 DPI 与渲染帧边界
+
+算力卡片、新闻区域卡片与普通/巡航详情卡共用 `--hud-detail-card-width`，标题、正文、元信息及摘要直接使用同一套 `info-panel.css` 规则。算力卡片、趋势图、图标、间距和控件尺寸均随根节点 `--hud-scale` 缩放；手动调整大小生成的内联像素尺寸会转换为相同比例的表达式。SVG 图表内部的 viewBox 单位随图表整体缩放，避免重复乘倍率。欧洲标题使用与正文同字体基线的小型 EU 字标，避免 Windows 将旗帜 emoji 展示为基线不同的字母。
+
+配置菜单保留独立的 340px 宽度和原有高度上限，不套用详情卡的宽高缩放。算力卡片标题保持共享 HUD 规格，内容区用更大的主数值、趋势图和说明间距支撑统一宽度。区域卡片的移动由 JS 时间补间独占，取消通用 HUD 的 CSS 位移过渡和强制 transform 合成层；最终 left/top 对齐设备像素，漂浮继续保留，连线使用同一显示位置。空间不足允许周边少量遮挡，卡片内容保持显示。
+
+全局选中对象是异构数据：卫星为 GeoJSON 对象，海缆是线对象，只有地表交互标记带 `userData.icon_layer_id`。`markerPresentationId` 仅为带该标识的对象生成堆叠身份，其余返回空，防止选中卫星时在帧内访问不存在的字段。
+
+`frame-stages.js` 为各独立更新阶段建立异常边界；某个卡片、标签或图层更新失败不会截断其他阶段和主场景绘制。失败会记录阶段和异常，按一秒间隔重试，切换选中对象时允许立即重试；成功后恢复正常更新。根因修复和正常场景无运行异常仍是验收要求，保护机制不替代修复。
+
+物件选中结果统一由 `showSelectionStatus(name)` 生成“已选择：名称”。普通点击、聚合子点、搜索定位和动捕确认共用该入口；`confirmInteractionCandidate` 的名称和反馈参数不再暗示仅适用于动捕。海缆图层只更新选中和图例状态，由交互入口通知一次，避免重复提示。已删除旧的锁定/定位/动捕确认消息键；真正的动捕模式切换和手势引导仍可标注动捕。
+
+### 详情卡信息精简
+
+常规详情保留对象身份、业务属性、时间与必要的数据可信度提示。卫星卡删除覆盖能力、当前显示和覆盖模型三项渲染说明，覆盖显示设置仍然有效；新闻详情删除 RSS 来源、源类型及抓取通道，保留媒体、分类、区域、发布时间和摘要。算力设施删除定位过程的来源、置信分、解析依据、匹配名称和核验时间，保留位置精度与核验状态；相同的 GPU 型号与芯片/平台只显示一次。来源状态等内部元信息不再展示，实际算力的精度/测量口径和原始来源仍保留。
+
+BGP 观测站移除重复的日常活跃度汇总，保留观测计数、事件时间、覆盖范围；BGP 事件置信度仍用于判断告警可靠性。海缆不再显示没有单一含义的经纬度行，自定义点不再显示内部记录 ID。船舶资料为空时不显示“资料缓存中”，也不展示补全置信分；船舶身份、动态、资料及来源保持可用。桌面和移动详情共用字段配置，底层数据与定位操作不受影响。
+
+### 多卡片与全量卫星的性能路径
+
+区域新闻与算力卡片保留共享深色表面、边框、阴影和文字，取消每张卡片对动态 WebGL/视频背景的实时 backdrop 滤镜及边缘 SVG 扭曲滤镜，并用 `contain: layout style` 限定布局影响。卡片仍按设备像素定位，未改动数量、内容、打字机或漂浮时序。
+
+`CalloutConnector` 的 SVG 视口只覆盖自身路径及节点/阴影留白，路径仍使用原始屏幕坐标；不再为每条短连线保留整屏 SVG 面积。地理锚点缓存不变的本地坐标，坐标变更会失效，世界变换和正背面判断逐帧更新。遮挡检查直接比较矩形，避免每个候选点与每个障碍物组合重复分配对象；HUD 障碍测量集中在该帧写入卡片样式前。
+
+卫星插值在端点直接复制采样数据，中间帧继续使用半径保持插值；尾迹仅提前拒绝原有误差界限下必不合格的高轨弦合并。重复选中/悬停索引不重写全量透明度缓冲。海缆与登陆点的固定本地矩阵不再逐帧重建，登陆点缩放变化显式更新矩阵，地球父级的世界矩阵仍正常传播。上述优化不减少卫星、轨迹样本或渲染分辨率。
+
+开发诊断可在 Earth URL 加 `?profileFrames=1`：`data-earth-frame-profile` 每秒输出各更新阶段的 CPU 均值、最大值和次数，默认关闭。GPU 名称见 `data-earth-gpu-renderer`。性能验收同时记录实际 canvas 像素尺寸、可见完整卡片数、卫星图层状态、缩放、直播状态和 30 秒平均 FPS；卡片未完成落位或仅调整到较小视口的读数不属于 1080p 全场景成绩。CPU 阶段计时不等于 GPU 耗时。
+
+## 详情卡配图
+
+`card-images.js` 在普通详情与巡航复用的 `showInfoCard` 路径中管理可选配图；桌面与移动详情共用 presenter。选择物件时按稳定标识请求 `/api/v1/earth/card-images/resolve`，卫星使用 NORAD，设施使用 `source:source_id`，海缆和登陆站使用各自来源 ID。数据适配只传身份，型号、分组及分类由后端当前记录解析，不在点击处理器中分散匹配。响应缓存最多 100 个身份、30 秒；同源后台保存通过 storage 版本事件使缓存失效并刷新当前卡片。请求不进入动画帧循环。
+
+`card-images.css` 同时用于后台预览和真实详情正文。独立绝对定位图片层覆盖右侧 68%，横向与自底向上的渐变通过 `mask-composite: intersect` 相交；WebKit 使用 `source-in`。图片自身不透明度为 0.85，使用 `saturate(1.2) contrast(1.1)`；图片层淡入终点为 1，不再叠加暗色遮罩或整体降透明度。内容在上层，标题保持原样，蒙版不作用于文字。原有 DPI、滚动、拖拽及连线不受图片尺寸影响；图片解码后淡入，reduced-motion 下直接显示。加载失败、无图、关闭或切到其他对象都会隐藏旧图片；异步请求与解码均检查选择代次，避免串图。标题中的图片来源链接提供署名和授权信息。
+
+后端 `card_image_configuration.py` 用独立的 `system_settings.earth_card_images` 保存资产与关联，沿用配置版本检查、行锁和审计事务，不改采集记录、不建并行采集状态。匹配顺序是物件、型号、分组、分类；专属“无图”阻断回退，停用资产不能被解析；授权状态作为真实来源记录保留，与启用开关分开。重复目标和悬空关联在 schema 层拒绝。默认值来自 `assets/cards/manifest.json`，无需数据库种子；保存时记录已知内置 ID，升级合并新内置项，按清单 previous_defaults 替换旧内置图片地址，同时保留用户修改的属性，保留已编辑或删除的旧项。容器构建同步复制同一清单，避免两份默认配置漂移。
+
+上传经 Pillow 校验 JPEG/PNG/WebP、尺寸及解码结果，原图保留，另生成 640/1280 边界的 WebP，正文按显示宽度与设备像素比选用。文件按内容哈希命名并原子写入，经公共只读 files 接口分发；管理、上传、目标搜索和预览需管理员权限。文件存储与备份见运维手册。内置 Frontier 实景只绑定该设施；Starlink 为系列示意图，不假定 V2/V3。千帆按用户要求启用系列配图，来源授权仍标记待确认。
+
+默认分类 `*` 覆盖卫星、算力设施、海缆、登陆站、船舶、BGP 事件、BGP 观测站和自定义点，在具体分类之后匹配。船舶使用 MMSI，BGP 使用 incident_key，观测站使用 collector_id，自定义点使用既有 ID；旧快照缺少身份时仅允许类型通用图，不冒充专属匹配。采集来源的 source_id 若因上游改名发生变化，需要重新关联。
+
+
+### 五类算力设施与默认配图
+
+算力类型为 `supercomputer`（超算中心）、`gpu_cluster`（GPU 集群）、`data_center`（数据中心）、`cloud_center`（云计算中心）和 `edge_node`（边缘计算节点）。前端 `compute-site-types.js` 统一标题、类型标签、计数与缺省类型；后端 `compute_types.py` 为 GeoJSON 与图片查询共用分类规则：有效的 metadata.site_type 优先，其次 data_type，最后使用已知采集源的类型。未识别设施按通用数据中心展示，不强制改成 GPU 集群。类型扩展不添加虚构设施或改变已采集记录的分类。
+
+五类均接入图例独立筛选、地图图标、详情卡、移动详情及图片身份。新类型详情复用设施身份、运营方、算力、功耗和位置字段；不沿用 GPU 数量或 TOP500 排名。主地图接受现有采集来源或明确声明算力类型的当前记录；地区设施查询保留快照时间和国家条件，三类基础设施不要求具有 GPU 算力计量合同，也不据此推算全球算力份额。当前内置采集器仍为 TOP500 / Epoch AI，新增类型不会自动产生记录。
+
+七张用户指定配图分别作为五类算力设施、BGP 观测站、BGP 事件的默认图。图库分类选项包含五类，无需等待某类已有数据。专属图片优先于类型图；旧内置图片及未自定义的 BGP 观测站关联按 manifest 的 previous_defaults / previous_rules 更新，手工修改的裁切、启用状态与专属绑定保留。
+
+
+### 保持显示行为的帧计算优化
+
+聚合展示在一次 update 内按父节点复用世界矩阵和相机局部坐标；跨帧强制刷新缓存，因此旋转、缩放、切换视角和筛选不会使用旧投影。完全收起且没有子 DOM 的聚合成员仍执行隐藏状态维护，但不计算看不见的展开坐标。计数和无变化的 ARIA 文案不重复写入 DOM。
+
+静态点批次仅在数据、选择、筛选、距离缩放或显式刷新时更新；选中物件的呼吸效果继续逐帧更新覆盖层。颜色缓存只接受不可变的字符串/数字，调用方可变 Color 对象不会被缓存。卫星圆点/光晕只更新其需要的地球父变换，避免各自遍历整棵地球节点。
+
+轨迹采样合并半径界限和第一轮误差扫描，使用原来的阈值与递归分割结果；未减少卫星数量、轨迹点、分辨率或任何卡片内容。确定性对比检查了 10,000 组历史样本，输出索引一致。局部 Bun 微基准（不是整页 FPS）：480 个聚合成员收起约 1.19→0.90 ms，展开约 4.47→2.86 ms；16,621 条轨迹扫描约 11.50→8.94 ms。端到端 FPS 仍需同分辨率、同卡片/卫星/视频状态、前台连续 30 秒单独比较。
+
+区域新闻卡的折叠按钮显式调用共享 HUD 控制器，正文复用 hud-panel__body--collapsible；aria-expanded 与真实折叠状态同步。仅用户点击触发折叠，布局和性能逻辑不自动隐藏卡片内容。
+
+物件详情浮窗与区域新闻卡共享 `--hud-detail-card-max-height`：390px 基准乘 HUD 缩放，并受视口减 24px 限制。标题固定，配图正文容器与内容组成 min-height:0 的 flex 链，仅正文滚动；内容少的卡片自然保持较短高度。BGP 事件优先显示事件/严重度/状态/影响区域/时间/摘要；观测站优先身份、状态及近期活跃；算力设施优先名称、算力和硬件，定位核验及来源后置。字段顺序来自共享 CARD_CONFIG，移动详情同步使用同一顺序。
+
+
+### 详情卡身份与连线一致性
+
+BGP 观测站以 collector 编号建立标记索引。共享索引不登记空 ID，重复 ID 不参与跨刷新替换；仍在当前图层中的点击对象直接保留自身引用。堆叠展示使用同一个 icon_item_id，避免详情、连线和选中置顶分别采用不同身份。BGP 聚合事件优先使用 incident_key，原始异常使用来源加 ID，防止不同来源的数字编号碰撞。
+
+卫星详情连线以 NORAD 识别卫星，并在数据数组替换时重新定位下标；选择高亮也在目录刷新后按同一 NORAD 重绑，目标消失则清除选择。轨道位置尚未就绪时不把零坐标当作连线锚点。海缆仍沿被选中海缆自己的几何取锚点，登陆点使用被点击标记，区域新闻/算力卡继续使用其区域锚点。
+
+
+算力详情配图解析在没有型号/分组规则时使用快速路径：由稳定 source 前缀确定超算或 GPU 分类，先匹配对象规则，再匹配分类默认图，跳过完整采集目录查询。只要管理员配置了型号或分组规则，就自动回退到完整目录解析；这不会改变前端身份、采集数据或其他物件类型。

-# 智能星球可交互图标聚类策略
+# 智能星球可交互图标聚合
 
-智能星球的可交互图标由 `createInteractableLayer` 统一管理。图标仍然使用 Three.js `Points` 渲染，拾取、hover、locked、tooltip 和巡航焦点继续依赖 marker 的 `userData`；聚类策略只决定“哪些 marker 被合成一个 cluster dot”。
+`interactable.js` 负责固定地理成员，`cluster-motion.js` 负责时间补间，`cluster-presentation.js` 负责圆形聚合、展开图标、拾取与 Spiderfy。普通独立标记继续使用 GPU Points；聚合成员从动画开始到终点由同一 DOM 图标显示，不再切回另一套位置。
 
-## 策略
+## 成员与缩放
 
-`cluster.strategy` 支持三种模式：
+聚合使用真实 `icon_base_position` 和球面分桶，默认距离 15（与地球半径同单位）、至少 2 个成员、每组至多 14 个。数据、筛选、显隐变化使缓存失效；旋转和缩放不改变成员。圆标锚在成员的球面质心，不参与屏幕避让。
 
-- `stable-spherical`：稳定球面聚类。按地球局部 3D 坐标聚合，并用 zoom band 缓存拓扑；旋转和同档缩放只更新投影和尺寸，不重算谁和谁聚在一起。适合 BGP、超算/GPU 中心和 Earth interactable 这类半静态图层。
-- `dynamic-screen`：动态屏幕聚类。保留原来的屏幕空间聚类逻辑，每帧按可见投影关系判断。适合船舶等高频实时图层，也可作为稳定策略的回退。
-- `none`：不聚类。所有 marker 独立显示，适合低数量或需要精确展示的图层。
+`cluster: { enabled: true }` 启用，`cluster: false` 关闭。可调项为 `distance`、`minCount`、`maxMarkersPerDot`、`disableAboveZoom`（默认 2.5）和 `expansionHysteresis`（默认 0.08）。界面缩放统一通过 `globeZoomForDistance()` 换算，超过 250% 自动展开，低于 230% 收拢；500% 不显示聚合圆标。卫星和 AIS 船只不接入本机制。
 
-`cluster: false` 等价于 `strategy: "none"`。未显式声明 `strategy` 时，保持兼容行为：开启聚类的旧图层继续走 `dynamic-screen`。
+## 动画与同坐标展开
 
-## Stable Spherical
+展开和收拢统一使用 320ms easeInOutCubic；停止滚轮后仍按时间完成，反向输入从当前进度续接。成员直接从质心插值到真实局部坐标，终点 DOM 保留，因此不存在动画终点与实际图标之间的切换。插值弦线可能暂入球体，显隐使用同方向球壳锚点判断，投影仍使用原插值位置，避免中途被误裁掉。
 
-`stable-spherical` 的核心是把聚类身份从屏幕距离迁到球面距离：
+只有同坐标或极近地理锚点（约 0.00015°）跨图层紧凑堆叠；屏幕重叠和城市粗网格不会把不同地点合并。每个图标以自己的真实投影为基准，整叠在每个轴向最多错开 24px，小组露出约 8–12px 点击边缘。稳定 ID 决定初始顺序，选中后排对象时移到前端，取消焦点后恢复原顺序。普通点展开终点严格等于真实投影，堆叠不改变经纬度或 marker 位置。
 
-- 每个 marker 使用 `icon_base_position` 作为真实地理锚点。
-- 默认 zoom 超过 `2.5` 时强制关闭聚类，所有 marker 展开为原图标。
-- 当前 zoom 只映射到离散 band；同一 band 内旋转地球或细微缩放不会重算拓扑。
-- 跨 band、数据变更、图层显隐变化时才重新计算 cluster。
-- cluster 质心由成员 3D 坐标平均后 normalize 回球壳半径，因此 cluster dot 刚性贴在地理质心投影上。
-- cluster dot 不参与 2D 避让，避免被屏幕排斥推离真实地理位置。
-- band 切换带有少量 hysteresis，避免缩放停在临界点时在两个 band 之间来回跳。
-- 新生成的 marker / cluster dot 会执行短 scale + opacity ease；这只是渲染过渡，不改变 marker 的真实经纬度、拾取对象或 locked 状态。
+## 交互与 BGP
 
-稳定策略使用球面 bucket/hash 邻域查询，禁止用全量双循环。这样大多数帧只承担投影与材质尺寸更新，聚类成本只在 band 或数据版本变化时支付。
+点击圆标展开并暂停自转。支线有 14px 透明命中区域，悬停同时强调对应支线与子点；点击任一处选择同一业务对象。画布容器统一处理画布和投影层的滚轮，HUD 的滚动不触发地球缩放。
 
-## 配置示例
+投影图标生成纹理时烘入原分类色。BGP 事件沿用告警颜色；包含 BGP 的聚合圆标及展开的事件图标使用扩散淡出光环，周期与大小来自 `BGP_CONFIG.ring`。GPU 中被投影替代的事件光环隐藏，避免在旧锚点重复绘制。减少动态效果偏好关闭脉冲动画。
 
-```js
-const computeCenterIconLayer = createInteractableLayer({
-  id: "computeCenters",
-  // ...
-  avoidance: SURFACE_AVOIDANCE_PROFILES.city,
-  cluster: {
-    strategy: "stable-spherical",
-    minCount: 2,
-    maxMarkersPerDot: 14,
-    transitionMs: 220,
-    bandHysteresis: 0.08,

-      { key: "far", maxZoom: 1.7, distance: 15 },

-      { key: "near", maxZoom: 3.5, distance: 4 },
-      { key: "detail", maxZoom: Infinity, distance: 0 },
-    ],
-  },
-});
-```
+## 已删除的旧实现
 
-实时层可以保留动态策略：
+低缩放圆点的桌面/移动端设置、存储字段、纹理、绘制/拾取分支和翻译均已删除。动态屏幕聚合、离散缩放分档、GPU 聚合圆点与旧的创建时缩放淡入路径也已删除，不提供旧策略回退。
 
-```js
-const vesselIconLayer = createInteractableLayer({
-  id: "vessels",
-  // ...
-  cluster: {
-    strategy: "dynamic-screen",
-    enabled: true,
-    maxMarkersPerDot: 10,
-  },
-});

+## 回归验证
 
-## 调参原则
+- 320ms 到达真实终点、反向连续、中间帧可见、终点保持同一节点。
+- 500% 无聚合圆标，同坐标成员可分别选中，源坐标保持不变。
+- 图层筛选/移除清理失效节点与 GPU 隐藏状态。
+- 图标和支线上滚轮可缩放，HUD 滚动除外。
+- 支线 hover 只联动对应子点；投影 BGP 纹理保留分类色。
 
-- `distance` 是球面 3D 距离阈值，单位与 `CONFIG.earthRadius` 一致。值越大，越容易聚合。
-- 最远 band 用较大的 `distance` 降低视觉密度；最近 band 通常设为 `0`，让图标完全解散。
-- `bandHysteresis` 控制 band 边界滞回。值太小容易临界闪烁，值太大会让切换略显迟钝。
-- `transitionMs` 控制聚散过渡时间。建议保持在 160-260ms，过长会让实时层显得拖泥带水。
-- `disableAboveZoom` 控制精细查看阈值。默认 `2.5`，超过后不再生成 cluster；设为 `false` 可关闭这个硬阈值。
-- 高实时性图层优先用 `dynamic-screen`，避免数据频繁变更时触发稳定策略的拓扑重算。
-- 若某图层出现异常，可临时切回 `dynamic-screen` 或 `cluster: false`。
+对应测试：`cluster-motion.test.js`、`cluster-presentation.test.js`、`globe-navigation.test.js`、`marker-badges.test.js`。
 
-## 验收重点
+## 刷新与首帧准备
 
-- 同一 zoom band 内旋转地球，cluster 不应闪烁或重新聚散。
-- cluster dot 应跟随地球表面质心，不被避让逻辑推开。
-- 放大到 detail band 后，应恢复该图层原本的图标纹理和点击行为。
-- zoom 超过 250% 后不应再显示 cluster dot。
-- vessel 等实时层更新后，图标和 cluster 应立即反映最新数据。
+数据刷新即使沿用聚合 ID，也必须按当前 Object3D 实例清理旧子节点。显示所有权变更立即重绘对应 GPU 批次；聚合拓扑失效同时废弃旧签名，避免旧圆标与独立图标并存。
+
+展开前先准备可见图标并等待图片解码，再开始 320ms 计时。同一纹理复用编码结果，不为背面的不可见成员创建图标，避免纹理准备耗时吞掉动画。回归覆盖重复刷新/缩放、首次纹理准备超过动画时长、选中前置/取消复位和卡片引线。

+| 海缆登陆点 | 琥珀 `#f59e0b`，浅金 `#fef3c7` 边圈 | 发光圆核 |
+| BGP 观测站 | 蓝色及原活动热度色 | 圆角矩形底板内置广播塔 |
+| BGP 事件 | 低/中/高/严重：蓝/琥珀/橙/红 | 不规则扁平符号（三角、感叹号、波动、爆发、泄漏），不使用方块 |
+| 船舶 | 货轮蓝、油轮橙、客船青绿、渔船琥珀、军舰靛紫、其他银灰 | 独立航向箭头，无徽标底板；停泊为圆点，悬停/选中发光 |
+| 自定义标记 | 地点绿、备注黄、告警红、默认蓝 | 地点针、备注页、告警三角 |
+
+BGP 变化事件保持不规则扁平符号作为唯一例外，观测站使用圆角徽标；其他有限地表物件使用缓存的徽标纹理，不为每个图标新增 DOM 或独立绘制对象。船舶继续按航向分桶，以顶点色区分船型，不将船型与航向相乘扩张批次数。卫星使用参考的鲜明类别色与无衬边硬圆盘；轨道和覆盖计算不变。低缩放圆点的设置、持久化字段和绘制/拾取分支已删除。
+
+
+### 卫星统一色板
+
+参考 [satellitemap.space](https://satellitemap.space/) 的类别色；本地 3d.html 中的模拟壳层与数量不作为项目分类依据。当前项目仍按真实轨道倾角分类：0–30° 蓝 `#3399ff`、30–60° 橙 `#ff801a`、60–90° 绿 `#00e680`、90–120° 紫 `#cc33ff`、120–180° 玫红 `#ff3366`，未知灰 `#94a3b8`。同一颗卫星跨昼夜保持同一颜色，预测轨道不再使用无关的黄紫渐变。
+
+覆盖统一 `#3399ff`，opacity=0.34，日侧透明度增益=1.65。普通点不带深色衬边，单批 `PointsMaterial` 使用 alphaTest=0.5；视觉尺寸由 `satellitePixelSize()` 在 2.4–8.0 之间平滑变化。
+
+### 选中轨道与面板轮廓
+
+预测轨道绘制完整周期的开放曲线，不追加首点，不截短采样范围或隐藏端部；按累计弧长沿未来采样方向推进亮色流光，复用同一 Line 绘制。电视与通用 HUD 外壳恢复方角，播放器裁剪区域同样为方角；不改变窗口尺寸与拖拽。发布代码移除临时逐帧性能统计，不保留只用于验收的 DOM 诊断接口。
+
+### 登陆点、侧面徽标与星空微调
+
+海缆与登陆点共用 R+0.48、renderOrder=1，均通过 `cable-surface.js` 的地表三角网格坐标生成，避免理想球与实际地表之间的端点视差。普通点为黄色实心圆与浅色圈，不带常驻光晕；只有 `related` 点在原有合批 Shader 中产生轻微脉动光晕，其他点变暗，取消高亮恢复普通黄色点。
+
+圆角徽标改为锚点遮挡：`surface-marker-occlusion.js` 在 GPU 判断锚点是否被球体挡住，正面徽标整块显示、背面整块隐藏；屏幕拾取复用相同判断。仅徽标层关闭逐像素深度裁切；BGP 变化事件保持原扁平符号与深度行为，观测站保留活动热度色并使用圆角底板。悬停、选中和聚合徽标使用同一遮挡路径。
+
+星空纹理材质独立使用 `CELESTIAL_CONFIG.skyBrightness = 1.0`；不改变地球曝光、天体灯光或业务图层亮度。
+
+船只为独立移动对象，恢复徽标改造前的航向箭头、停泊圆点和悬停/选中光晕，不接入固定地表物件的圆角底板及整块徽标遮挡路径。
+
+登陆点普通态和关联态均保持橙色内芯、黄色外圈；关联态只扩大外侧柔光区域并脉动，不改变核心颜色、透明度或尺寸。取消关联后光晕归零；非关联点继续使用暗态。
+
+
+### 星空颜色输出
+
+星空贴图按 sRGB 解码；`celestial.js` 通过共享 `preserveTextureOutput()` 仅为星空材质补齐屏幕 sRGB 输出。Three.js r128 的全局 renderer 仍保持既有线性输出，避免改变地球、卫星及其他图层。`skyBrightness=1.0` 表示原图亮度；缺少输出编码时，解码后的暗部会再次以线性数值显示，不能靠提高倍率修正。验证应固定星图、相机与视角，对比渲染像素和 1.0/1.5 两档响应，不能只检查加载成功。
+
+卫星 hover 小圈直接使用当前卫星的倾角类别色，与粒子和图例一致；切换悬停对象时重新取色，位置更新不覆盖颜色。
+
+所有地表卡片统一使用根 HUD DPI 比例。新闻区域卡片与巡航新闻复用标题图标、配色、字号及内边距；区域版只精简元信息字段并增加独立轮播控件。算力指标数字、趋势图及标题图标不再使用未缩放的固定像素。欧洲使用小型 EU 字标，其他区域使用受同一比例约束的代表 emoji。
+
+算力图标按五类选择：超算芯片、GPU 层叠、数据中心机柜、云计算云朵、边缘节点连接。几何分别来自 compute-supercomputer.svg、compute-gpu-cluster.svg、compute-hdd-network.svg、compute-cloud.svg、compute-edge.svg，保持算力图层紫色底板与原有选中行为。

+## Windows 桌面启动器
+
+启动窗口优先使用 Windows Terminal，并显式运行 PowerShell 7（`pwsh.exe`），不依赖 Terminal 默认配置文件。未安装 PowerShell 7 时回退到 Windows PowerShell；未安装 Terminal 时直接启动可用的 PowerShell。CMD 初始引导同样优先 PowerShell 7。普通入口请求提权，已经以管理员运行的入口也会进入新 Terminal 窗口，但不会再次请求提权；子窗口校验权限后直接执行 WSL，避免递归打开窗口。重启完成后仍保留原有 WSL shell。
+
+首次在 Windows 文件资源管理器中打开实际项目目录，双击仓库根目录的 `planet.cmd`。它从自身位置识别 WSL 发行版和 Linux 项目目录，在 Windows 当前用户的实际桌面生成 `Planet.cmd`，随后进入正常重启流程。支持 `\\wsl$\发行版\...` 与 `\\wsl.localhost\发行版\...`；仓库位于 Windows 本地磁盘时，使用默认 WSL 发行版及 `wslpath` 映射。系统桌面位置由 Windows 获取，兼容不同用户名和 OneDrive 等桌面重定向；WSL、zsh 及项目依赖仍须先准备好。
+
+后续双击桌面副本，使用已绑定的发行版与目录，申请原有管理员权限，并调用 `planet.sh restart --allow-lan`。不写入测试端口；默认前端 3000、后端 8000、AI Provider 8010，显式 `DEFAULT_*_PORT` 环境配置仍有效。成功后按实际 `ports.env` 端口打开 Earth，终端保留 WSL shell；失败只显示错误，不打开成功页面。源文件负责生成入口，`scripts/windows/planet-launcher.ps1` 负责 Windows 路径、桌面安装与提权，`scripts/windows/restart.zsh` 只衔接现有重启流程。
+
+只生成或检查副本而不重启服务，可在 Windows 中运行 `planet.cmd --install-only`。从仓库再次运行会刷新同一目标的副本；已有其他项目或非托管 `Planet.cmd` 时另存带目标标识的文件，不覆盖。目录移动后从新位置重新运行仓库入口，旧副本不会猜测新目录。桌面副本依赖项目中的脚本，不是可脱离仓库运行的安装包。
+
+不要把仓库原始 `planet.cmd` 单独复制到桌面，它需要相邻的 `scripts/windows/` 才能完成首次生成。换电脑时应从新电脑的项目目录重新生成，不能直接沿用旧电脑的桌面副本。服务器的 `/home/linkong/planet` 与个人电脑的其他路径均可使用，不必修改提交到 Git 的路径。应在拥有目标 WSL 发行版的 Windows 账号下运行；若提权时改用其他账号，其 WSL 发行版注册可能不同。首次生成不要求管理员权限，真正重启时才申请提权。
+
+Windows 回归命令为 `powershell.exe -NoProfile -ExecutionPolicy Bypass -File scripts\harness\test_windows_launcher.ps1`，覆盖路径识别、特殊字符、生成副本及名称冲突。`scripts/harness/test_windows_restart.py` 用临时替身验证重启参数、成功打开页面和失败保留 shell，已接入 quick-check，不启动实际服务。
+
+## 启动背景
 
 日常启动使用 `zsh ./planet.sh start --non-motion-agent`；新环境首次准备才需要 `init`。排查耗时时，应区分首次依赖下载、容器就绪和应用初始化，结合阶段日志时间判断。
