+
+# /cleanup — 垃圾代码审查与清理
+
+分析当前工作区（git diff）中的未提交代码，找出并修复常见垃圾代码，**不得改变任何运行逻辑**。
+
+## 检查范围
+
+若 `$ARGUMENTS` 非空，则只检查指定文件/目录；否则检查所有未提交修改（`git diff HEAD`）。
+
+## 审查清单
+
+按优先级检查以下问题（只报告在本次 diff 中**新增或修改**的代码里存在的问题）：
+
+### 1. 重复逻辑 (Duplicate Logic)
+- 完全相同或高度相似的代码块在多处出现
+- 同一函数/方法被多个地方各自实现，已有公共版本未被复用
+- 相同的 DOM 查询、正则、模板字符串在同一文件重复
+
+### 2. Magic Numbers / Magic Strings
+- 裸数字直接参与计算（如偏移量、时间、尺寸、阈值），没有命名常量
+- 硬编码字符串（如 id 名、状态值、URL 片段）散落在逻辑中
+- 例外：`0`, `1`, `-1`, `100`, `""` 等语义明确的惯用值不算
+
+### 3. 命名问题
+- 含义不明的缩写变量（如 `or_`, `tmp2`, `x2`）
+- 命名与实际用途不符
+- 同一概念在不同地方用不同名字表达
+
+### 4. 死代码 / 无效代码
+- 注释掉的旧代码块（3行以上）
+- 声明后从未使用的变量/参数/导入
+- 永远不会执行的条件分支
+
+### 5. 代码风格问题
+- 尾部空白字符（trailing whitespace）
+- 同一文件内风格不一致（如混用单双引号、缩进不统一）
+- 空行使用不一致（连续多个空行等）
+
+### 6. 其他常见问题
+- 私有辅助函数应被 export 但没有，导致调用方重复实现
+- 类型/接口重复定义
+- 过于冗长的条件表达式可以简化（不改逻辑）
+
+## 执行步骤
+
+### Step 1 — 获取待检查文件列表
+
+```bash
+# 无参数时：获取所有未提交修改
+git diff HEAD --name-only
+
+# 有参数时：用 $ARGUMENTS 过滤
+```
+
+### Step 2 — 逐文件阅读并分析
+
+- 用 Read 工具读取完整文件（不只读 diff）
+- 对照审查清单，记录每个问题：文件名、行号、问题类型、建议修复方式
+
+### Step 3 — 报告问题清单
+
+在修改前，先以列表形式输出所有发现的问题：
+
+```
+发现 N 个问题：
+
+[文件] js/foo.js
+  · L34, L78: 重复逻辑 — 两处都实现了相同的 DOM 查询，可提取到 getPanel()
+  · L91: Magic number — 硬编码 14 作为偏移量，应命名为 TOOLTIP_OFFSET
+
+[文件] js/bar.js
+  · L12: 命名问题 — 变量 `or_` 语义不明，应命名为 outerR/outerG/outerB
+  ...
+```
+
+如果没有发现问题，直接输出"未发现垃圾代码，当前代码质量良好。"并停止。
+
+### Step 4 — 执行修复
+
+对每个问题，使用 Edit 工具进行**最小化修改**：
+
+- **重复逻辑**：提取为共享常量/函数，更新所有调用点
+- **Magic number**：在文件顶部或逻辑附近声明 `const NAME = value`，替换所有引用
+- **命名问题**：重命名变量，更新所有使用处
+- **死代码**：直接删除
+- **尾部空白/风格**：修正
+- **未 export 的函数**：添加 `export`，在调用方改为导入（不重复实现）
+
+**修复原则：**
+- 只改在审查清单中发现的问题，不做额外优化
+- 每次 Edit 只修改确实有问题的行，保持 diff 最小
+- 改完后用 `grep` 验证旧的坏代码已消失
+
+### Step 5 — 输出总结
+
+```
+清理完成：
+
+修复了 N 个问题：
+  ✓ earth.js — 提取重复 vertexShader 为 ATMOS_VERTEX_SHADER 常量
+  ✓ main.js — 提取 TOOLTIP_CURSOR_OFFSET = 14（4处引用）
+  ✓ controls.js — export updateLayerButtonState，移除 main.js 中的重复实现
+  ...
+
+未修改的问题（需人工确认）：
+  ! foo.js L45 — 注释代码块较长，建议手动确认是否可删除
+```
+
+## 约束
+
+- **禁止**改变函数签名、接口定义、导出 API（除非问题正是私有函数应被 export）
+- **禁止**添加新功能、新抽象、新参数
+- **禁止**修改注释内容（只删除注释掉的死代码）
+- **禁止**修改测试文件逻辑
+- 如果一个 Magic number 的语义不完全确定，**跳过**，在总结中标记为"需人工确认"

+# /release — Planet 发版工作流
+
+## 版本号规则
+
+| 变更类型 | 版本跳动 | 适用场景 |
+|---------|---------|---------|
+| `feature` | `+0.1.0` | 纯新功能，无 bugfix |
+| `improvement` | `+0.0.1` | UI 调整、小功能增强、bugfix 混合，或以 UI/体验改进为主的迭代 |
+| `bugfix` | `+0.0.1` | 纯 bug 修复，无新功能 |
+| `docs` / `maintenance` / `refactor` | 默认不发版，除非用户明确要求 |
+
+意图混合时以用户明确描述为准；bugfix + 小 feature 混合默认判定为 `improvement`（`+0.0.1`）。
+
+## 必须同步更新的文件
+
+使用 `git rev-parse --show-toplevel` 获取仓库根目录，以下路径均相对于根目录：
+
+- `VERSION`
+- `frontend/package.json`（`"version"` 字段）
+- `pyproject.toml`（`version =` 字段）
+- `uv.lock`（**不要手动编辑**，通过 `uv lock` 重新生成）
+- `docs/CHANGELOG.md`
+- `docs/version-history.md`
+
+## 执行步骤
+
+### Step 1 — 环境检查
+
+```bash
+git branch --show-current          # 确认在 dev 分支
+git status --short                 # 检查是否有无关的未暂存修改
+cat VERSION                        # 读取当前版本
+```
+
+若当前**不在 `dev` 分支**，停下来告知用户，不要继续。
+
+若存在无关的未暂存修改，列出并询问用户是否一并提交，或先 stash。
+
+### Step 2 — 确定发版类型与新版本号
+
+- 若 `$ARGUMENTS` 提供了明确类型（`feature` / `bugfix`），直接使用
+- 否则根据当前 `git diff HEAD` 和 `git log` 推断
+- 计算新版本号（例：`0.26.2` → bugfix → `0.26.3`）
+- **先输出发版计划供用户确认**：
+
+```
+发版计划：
+  类型：bugfix
+  版本：0.26.2 → 0.26.3
+  分支：dev
+  将更新：VERSION, frontend/package.json, pyproject.toml, uv.lock, CHANGELOG.md, version-history.md
+```
+
+### Step 3 — 更新版本号文件
+
+按顺序更新（每步用 Edit 工具，精确替换，不要重写整个文件）：
+
+1. `VERSION` — 直接替换全部内容为新版本号
+2. `frontend/package.json` — 替换 `"version": "x.x.x"` 行
+3. `pyproject.toml` — 替换 `version = "x.x.x"` 行
+4. 运行 `uv lock` 重新生成 `uv.lock`（在仓库根目录下执行）
+
+### Step 4 — 更新 CHANGELOG.md
+
+在文件顶部插入新条目，格式：
+
+```markdown
+## [x.x.x] — YYYY-MM-DD
+
+### ✨ Features / 🐛 Fixes / 🔧 Improvements
+- ...（只列高信号条目，最多 5 条）
+- ...
+
+---
+```
+
+日期使用 `date +%Y-%m-%d` 获取今天的日期。
+
+### Step 5 — 更新 docs/version-history.md
+
+- 更新文件头部的"当前开发版本"字段
+- 在时间线表格顶部插入新行：`| vx.x.x | YYYY-MM-DD | 一句话摘要 |`
+
+### Step 6 — 验证
+
+针对本次变更范围做最小验证：
+
+- Python 文件有修改：`python3 -m py_compile <changed_files>`
+- Frontend 文件有修改：运行项目标准检查（若无则跳过并说明）
+- 版本号一致性检查：用 grep 确认 VERSION、package.json、pyproject.toml 中的版本号完全一致
+
+```bash
+grep -h "version" VERSION frontend/package.json pyproject.toml
+```
+
+### Step 7 — 提交前预览
+
+展示将要提交的文件列表：
+
+```bash
+git diff --stat HEAD
+```
+
+再次确认所有必须文件都在变更列表中，**不包含**非预期文件（如调试文件、.env 等）。
+
+### Step 8 — Commit & Push（用户确认后）
+
+```bash
+git add VERSION frontend/package.json pyproject.toml uv.lock docs/CHANGELOG.md docs/version-history.md
+# 若有代码变更也一并 stage
+git add <code_files>
+
+git commit -m "release: bump version to x.x.x"
+git tag vx.x.x
+git push origin dev
+git push origin vx.x.x
+```
+
+commit message 固定格式：`release: bump version to x.x.x`
+
+### Step 9 — 完成确认
+
+输出摘要：
+
+```
+✓ 版本号已更新：0.26.2 → 0.26.3
+✓ CHANGELOG 已更新
+✓ version-history 已更新
+✓ uv.lock 已重新生成
+✓ 验证通过
+✓ commit: release: bump version to 0.26.3
+✓ tag: v0.26.3
+✓ 已 push 到 origin/dev
+```
+
+## 注意事项
+
+- `uv.lock` 只能通过 `uv lock` 生成，绝不手动编辑
+- 发版 commit 只包含版本文件 + 本次功能代码，不混入无关改动
+- 若环境中 `uv` 不可用，说明原因并跳过 lockfile 更新，提醒用户手动运行

+
+# Cleanup
+
+Review and fix code quality issues in the current working tree without altering any logic or behavior.
+
+## When To Use
+
+- The user asks to clean up, tidy, or lint uncommitted changes
+- The user wants a code smell review before releasing or committing
+- The user mentions magic numbers, duplicate logic, dead code, or naming issues
+
+Do not refactor architecture, add features, or change behavior.
+
+## Scope
+
+If the user specifies a file or directory, check only that. Otherwise check all uncommitted changes (`git diff HEAD`).
+
+Only report issues present in **newly added or modified** lines of this diff — do not audit unchanged code.
+
+## Checklist
+
+### 1. Duplicate Logic
+- Identical or near-identical code blocks appearing in multiple places
+- A function/helper that already exists but is re-implemented elsewhere instead of being reused
+- Repeated DOM queries, regex literals, or template strings within the same file
+
+### 2. Magic Numbers / Magic Strings
+- Bare numeric literals used in calculations (offsets, timeouts, sizes, thresholds) without a named constant
+- Hardcoded strings (IDs, status values, URL fragments) scattered through logic
+- Exceptions: `0`, `1`, `-1`, `100`, `""` and other idiomatically clear values are fine
+
+### 3. Naming Issues
+- Cryptic abbreviations (`or_`, `tmp2`, `x2`)
+- Names that do not match actual behavior
+- The same concept referred to by different names in different places
+
+### 4. Dead Code
+- Commented-out code blocks (3+ lines)
+- Variables, parameters, or imports declared but never used
+- Branches that can never execute
+
+### 5. Style Inconsistencies
+- Trailing whitespace
+- Mixed quote styles or indentation within the same file
+- Inconsistent blank-line usage (multiple consecutive blank lines, etc.)
+
+### 6. Other
+- Private helper functions that should be exported but are not, causing callers to duplicate the implementation
+- Overly verbose conditions that can be simplified without changing logic
+
+## Steps
+
+### Step 1 — Get the file list
+
+```bash
+git diff HEAD --name-only
+```
+
+Filter to the user-specified path if one was provided.
+
+### Step 2 — Read and analyze each file
+
+Read the full file (not just the diff) with the Read tool. For each file, record every issue found: filename, line number, category, and suggested fix.
+
+### Step 3 — Report findings before touching anything
+
+Print a structured list:
+
+```
+Found N issues:
+
+[file] js/foo.js
+  · L34, L78: Duplicate logic — same DOM query implemented twice; extract to getPanel()
+  · L91: Magic number — bare 14 used as pixel offset; name it TOOLTIP_OFFSET
+
+[file] js/bar.js
+  · L12: Naming — variable `or_` is unclear; rename to outerR, outerG, outerB
+  ...
+```
+
+If no issues are found, output "No code smells detected. Code quality looks good." and stop.
+
+### Step 4 — Fix each issue
+
+Use the Edit tool for **minimal, targeted changes**:
+
+- **Duplicate logic**: extract to a shared constant or function; update all call sites
+- **Magic number/string**: declare `const NAME = value` near the top of the relevant scope; replace all usages
+- **Naming**: rename the variable/function; update all references
+- **Dead code**: delete it
+- **Trailing whitespace / style**: fix in place
+- **Unexported helper**: add `export`; update callers to import instead of re-implementing
+
+Principles:
+- Only fix issues identified in the checklist — no extra improvements
+- Keep each Edit as small as possible
+- After fixing, verify the old bad pattern is gone with grep
+
+### Step 5 — Summary
+
+```
+Cleanup complete:
+
+Fixed N issues:
+  ✓ earth.js — extracted duplicate vertexShader into ATMOS_VERTEX_SHADER constant
+  ✓ main.js — extracted TOOLTIP_CURSOR_OFFSET = 14 (4 references updated)
+  ✓ controls.js — exported updateLayerButtonState; removed duplicate implementation in main.js
+  ...
+
+Skipped (needs manual review):
+  ! foo.js L45 — large commented-out block; confirm it is safe to delete
+```
+
+## Constraints
+
+- **Do not** change function signatures, exported interfaces, or public APIs (unless the issue is a missing export)
+- **Do not** add new features, abstractions, or parameters
+- **Do not** rewrite comments (only delete commented-out dead code)
+- **Do not** touch test file logic
+- If a magic number's intent is uncertain, skip it and flag it in the summary

+name: release
+description: Use when the user asks to release, bump version, update changelog/version files, or commit/push a repository release for the Planet repo. Determines version bump type from changes, updates all required version-bearing files, updates changelog and version-history, runs minimal validation, then commits, tags, and pushes.

+
+# Release Workflow
+
+Use this skill for release-oriented work in this repository.
+
+## When To Use
+
+- The user asks to `发版`
+- The user asks to bump a version
+- The user asks to update `CHANGELOG`, `version-history`, or version files as part of a release
+- The user asks to commit/push a release or a publishable bugfix/feature bundle
+
+Do not use this skill for ordinary commits that are not being released.
+
+## Versioning Rules
+
+- `feature` -> bump `+0.1.0`
+- `bugfix` -> bump `+0.0.1`
+- `docs`, `maintenance`, and `refactor` do not bump by default unless the user explicitly wants a release
+
+When intent is mixed, prefer the user's stated release intent.
+
+## Required Files
+
+Use `git rev-parse --show-toplevel` to get the repo root. All paths are relative to it:
+
+- `VERSION`
+- `frontend/package.json` (`"version"` field)
+- `pyproject.toml` (`version =` field)
+- `uv.lock` (**never edit manually** — regenerate by running `uv lock`)
+- `docs/CHANGELOG.md`
+- `docs/version-history.md`
+
+## Workflow
+
+### Step 1 — Environment check
+
+```bash
+git branch --show-current   # must be on dev
+git status --short           # check for unrelated uncommitted changes
+cat VERSION                  # read current version
+```
+
+If not on `dev`, stop and tell the user. Do not proceed.
+
+If unrelated uncommitted changes exist, list them and ask the user whether to include them or stash first.
+
+### Step 2 — Determine release type and next version
+
+- If the user provided an explicit type (`feature` / `bugfix`), use it
+- Otherwise infer from `git diff HEAD` and recent `git log`
+- Compute the next version (e.g. `0.26.2` → bugfix → `0.26.3`)
+- **Show the release plan before making any changes:**
+
+```
+Release plan:
+  Type:    bugfix
+  Version: 0.26.2 → 0.26.3
+  Branch:  dev
+  Will update: VERSION, frontend/package.json, pyproject.toml, uv.lock, CHANGELOG.md, version-history.md
+```
+
+### Step 3 — Update version files
+
+Update in order (use Edit for precise replacement, never rewrite whole files):
+
+1. `VERSION` — replace entire content with new version string
+2. `frontend/package.json` — replace `"version": "x.x.x"` line
+3. `pyproject.toml` — replace `version = "x.x.x"` line
+4. Run `uv lock` at repo root to regenerate `uv.lock`
+
+### Step 4 — Update CHANGELOG.md
+
+Insert a new entry at the top of the file:
+
+```markdown
+## x.x.x
+
+Released: YYYY-MM-DD
+
+### Highlights
+
+- ...
+
+### Added / Fixed / Improved
+
+- ... (high-signal items only, max 5)
+
+---
+```
+
+Get today's date with `date +%Y-%m-%d`.
+
+### Step 5 — Update docs/version-history.md
+
+- Update the "current dev version" field in the file header
+- Insert a new row at the top of the timeline table: `| vx.x.x | YYYY-MM-DD | one-line summary |`
+
+### Step 6 — Validate
+
+Run the smallest relevant validation for the changes in scope:
+
+- Python files changed: `python3 -m py_compile <changed_files>`
+- Frontend files changed: run the project-standard check if available; otherwise skip and say so
+- Version consistency: confirm VERSION, package.json, pyproject.toml, and uv.lock all show the same version
+
+```bash
+grep -h "version" VERSION frontend/package.json pyproject.toml
+```
+
+### Step 7 — Pre-commit preview
+
+Show what will be committed:
+
+```bash
+git diff --stat HEAD
+```
+
+Confirm all required files are present and no unexpected files (debug files, `.env`, etc.) are included.
+
+### Step 8 — Commit, tag, and push
+
+```bash
+git add VERSION frontend/package.json pyproject.toml uv.lock docs/CHANGELOG.md docs/version-history.md
+# also stage any code changes included in this release
+git add <code_files>
+
+git commit -m "release: bump version to x.x.x"
+git tag vx.x.x
+git push origin dev
+git push origin vx.x.x
+```
+
+Commit message format is fixed: `release: bump version to x.x.x`
+
+### Step 9 — Completion summary
+
+```
+✓ Version bumped: 0.26.2 → 0.26.3
+✓ CHANGELOG updated
+✓ version-history updated
+✓ uv.lock regenerated
+✓ Validation passed
+✓ commit: release: bump version to 0.26.3
+✓ tag: v0.26.3
+✓ Pushed to origin/dev
+```
+
+## Notes
+
+- `uv.lock` must only be updated by running `uv lock`, never manually
+- The release commit should include only version files + the code for this release — no unrelated changes
+- If `uv` is unavailable in the environment, say so explicitly and remind the user to run it manually

+- [ ] 如果后续明确需要“账号级同步 Earth 偏好”，再单独设计 `Earth user preferences`：优先按用户维度而不是全局系统设置保存，并规划 `localStorage -> backend` 的平滑迁移策略
+- [ ] 把 Earth 态势新闻源从 [earth_news.py](/home/ray/dev/linkong/planet/backend/app/services/earth_news.py) 的硬编码列表抽成可配置目录，优先保持当前“实时聚合”链路不变，只先解决新闻源不可配置的问题
+- [ ] 为 Earth 态势新闻设计后续采集器化方案：明确新闻数据模型、去重策略、区域映射、过期清理和 Earth/AI 复用方式，再决定何时把新闻从实时抓取升级成正式 collector

+---
+
+## 0.26.1
+
+Released: 2026-04-12
+
+### Highlights
+
+- Cleaned up the first TV follow-up and replaced the dashboard sidebar's brittle one-off scroll behavior with a reusable `Scrollbar` component, so the new live module code is easier to maintain and the console navigation can scroll without layout jitter.
+
+### Improved
+
+- Improved [frontend/src/components/Scrollbar/Scrollbar.tsx](/home/ray/dev/linkong/planet/frontend/src/components/Scrollbar/Scrollbar.tsx), [frontend/src/components/AppLayout/AppLayout.tsx](/home/ray/dev/linkong/planet/frontend/src/components/AppLayout/AppLayout.tsx), and [frontend/src/index.css](/home/ray/dev/linkong/planet/frontend/src/index.css) by extracting the sidebar scrollbar into a dedicated component with explicit `x / y / both` axis support, hidden native scrollbars, compact account/version rows, and a sidebar-only vertical setup instead of the earlier patchwork CSS glued directly onto the layout.
+
+### Fixed
+
+- Fixed [frontend/public/earth/js/tv.js](/home/ray/dev/linkong/planet/frontend/public/earth/js/tv.js) by refactoring repeated iframe/video reset paths into shared helpers, so TV source switching, empty-state fallback, and playback retry handling no longer duplicate cleanup logic across multiple branches.
+
+## 0.26.2
+
+Released: 2026-04-12
+
+### Highlights
+
+- Stabilized the new reusable scrollbar work by restoring reliable sidebar visibility and extending the same floating scrollbar language to the Data Sources tables without letting scrollbars squeeze layout width or regress the console navigation.
+
+### Added
+
+- Added [frontend/src/components/Scrollbar/ScrollbarOverlay.tsx](/home/ray/dev/linkong/planet/frontend/src/components/Scrollbar/ScrollbarOverlay.tsx) as an overlay variant that binds to existing scroll containers such as Ant Table bodies, so heavy data grids can adopt the new scrollbar visuals without replacing their built-in scrolling mechanics.
+
+### Improved
+
+- Improved [frontend/src/components/Scrollbar/Scrollbar.tsx](/home/ray/dev/linkong/planet/frontend/src/components/Scrollbar/Scrollbar.tsx), [frontend/src/components/AppLayout/AppLayout.tsx](/home/ray/dev/linkong/planet/frontend/src/components/AppLayout/AppLayout.tsx), and [frontend/src/index.css](/home/ray/dev/linkong/planet/frontend/src/index.css) by reverting the sidebar to a reliable vertical-first scrollbar path, then reintroducing automatic dual-axis support with independent floating tracks that no longer hide the thumb when only the sidebar needs vertical scrolling.
+
+### Fixed
+
+- Fixed [frontend/src/pages/DataSources/DataSources.tsx](/home/ray/dev/linkong/planet/frontend/src/pages/DataSources/DataSources.tsx) and [frontend/src/index.css](/home/ray/dev/linkong/planet/frontend/src/index.css) so the built-in and custom datasource tables now use the new overlay scrollbar instead of native table scrollbars, keeping horizontal and vertical scrolling available without changing Ant Table’s internal layout behavior.
+
+## 0.26.0
+
+Released: 2026-04-12
+
+### Highlights
+
+- Added an operator-facing TV live module to Earth, including backend-configurable live sources, a draggable/resizable live-news HUD window, default global news channels, and a dedicated settings workflow so the Earth page can open real news playback instead of only static telemetry.
+
+### Added
+
+- Added [backend/app/api/v1/tv.py](/home/ray/dev/linkong/planet/backend/app/api/v1/tv.py), [backend/app/services/tv_streams.py](/home/ray/dev/linkong/planet/backend/app/services/tv_streams.py), and [backend/app/services/collectors/news_live_streams.py](/home/ray/dev/linkong/planet/backend/app/services/collectors/news_live_streams.py) to provide TV source configuration, public stream payloads, a guarded HLS proxy path, and a collector entry point for future world-news live-source ingestion.
+- Added the Earth TV HUD workspace through [frontend/public/earth/index.html](/home/ray/dev/linkong/planet/frontend/public/earth/index.html), [frontend/public/earth/js/tv.js](/home/ray/dev/linkong/planet/frontend/public/earth/js/tv.js), and [frontend/public/earth/css/tv-panel.css](/home/ray/dev/linkong/planet/frontend/public/earth/css/tv-panel.css), including toolbar access, draggable/closable behavior, resize support, direct video/HLS playback, iframe fallback, and per-channel external-open handling.
+- Added [docs/deprecated/earth-tv-live-module-plan.md](/home/ray/dev/linkong/planet/docs/deprecated/earth-tv-live-module-plan.md) and [docs/earth/technical/news-live-streams-collector-format.md](/home/ray/dev/linkong/planet/docs/technical/earth-news-live-streams-collector-format.md) to document the TV module rollout plan and the expected collector payload format for future curated live-channel ingestion.
+
+### Improved
+
+- Improved [frontend/src/pages/Settings/Settings.tsx](/home/ray/dev/linkong/planet/frontend/src/pages/Settings/Settings.tsx), [backend/app/api/v1/settings.py](/home/ray/dev/linkong/planet/backend/app/api/v1/settings.py), and [backend/app/core/datasource_defaults.py](/home/ray/dev/linkong/planet/backend/app/core/datasource_defaults.py) by adding TV source administration to system settings and registering the `news_live_streams` datasource as a first-class configurable collector.
+- Improved [backend/app/services/tv_streams.py](/home/ray/dev/linkong/planet/backend/app/services/tv_streams.py) by seeding a curated first-pass news channel catalog that now defaults to `CGTN English` YouTube playback while keeping `CCTV-4` as a built-in fallback and exposing additional Reuters, CGTN, DW, Al Jazeera, Arirang, ABP, and SABC entries for operator testing.
+
+### Fixed
+
+- Fixed [frontend/public/earth/js/tv.js](/home/ray/dev/linkong/planet/frontend/public/earth/js/tv.js) and [frontend/public/earth/index.html](/home/ray/dev/linkong/planet/frontend/public/earth/index.html) so HLS/video playback now actively attempts autoplay in the TV panel instead of only loading metadata and leaving the player visually idle.
+- Fixed [frontend/public/earth/css/tv-panel.css](/home/ray/dev/linkong/planet/frontend/public/earth/css/tv-panel.css) so the TV source selector and action controls better match the Earth HUD dark theme instead of falling back to a bright native dropdown presentation.
+
+## 0.25.3
+
+Released: 2026-04-11
+
+### Highlights
+
+- Refined the Earth HUD visual system into a calmer operator-facing style, turned the top-left Earth brand into a real reusable component with language-driven rendering, and cleaned up duplicated brand assets so the page now has a single source of truth for HUD branding.
+
+### Added
+
+- Added [frontend/public/earth/js/brand.js](/home/ray/dev/linkong/planet/frontend/public/earth/js/brand.js) as a reusable Earth `brand` component that renders the top-left logo/title/subtitle block from a shared config instead of hardcoding the structure in HTML.
+- Added [frontend/public/earth/assets/brand/earth-logo.svg](/home/ray/dev/linkong/planet/frontend/public/earth/assets/brand/earth-logo.svg), [frontend/public/earth/assets/brand/title-zh.svg](/home/ray/dev/linkong/planet/frontend/public/earth/assets/brand/title-zh.svg), and [frontend/public/earth/assets/brand/title-en.svg](/home/ray/dev/linkong/planet/frontend/public/earth/assets/brand/title-en.svg) as the canonical Earth brand asset set.
+
+### Improved
+
+- Improved [frontend/public/earth/css/base.css](/home/ray/dev/linkong/planet/frontend/public/earth/css/base.css), [frontend/public/earth/css/hud.css](/home/ray/dev/linkong/planet/frontend/public/earth/css/hud.css), [frontend/public/earth/css/coordinates-display.css](/home/ray/dev/linkong/planet/frontend/public/earth/css/coordinates-display.css), [frontend/public/earth/css/legend.css](/home/ray/dev/linkong/planet/frontend/public/earth/css/legend.css), [frontend/public/earth/css/earth-stats.css](/home/ray/dev/linkong/planet/frontend/public/earth/css/earth-stats.css), and [frontend/public/earth/css/toolbar.css](/home/ray/dev/linkong/planet/frontend/public/earth/css/toolbar.css) by rebalancing the Earth HUD into a more restrained deep-blue control-room look instead of the earlier over-layered glass-and-neon mix.
+- Improved [frontend/public/earth/index.html](/home/ray/dev/linkong/planet/frontend/public/earth/index.html), [frontend/public/earth/js/main.js](/home/ray/dev/linkong/planet/frontend/public/earth/js/main.js), and [frontend/public/earth/js/constants.js](/home/ray/dev/linkong/planet/frontend/public/earth/js/constants.js) by moving the Earth brand mount to a dedicated root and letting `HUD_CONFIG.brandLanguage` choose between `zh` and `en` without embedding the language decision in the DOM.
+
+### Fixed
+
+- Fixed [frontend/public/earth/css/info-panel.css](/home/ray/dev/linkong/planet/frontend/public/earth/css/info-panel.css) so the Earth brand area now uses consistent `earth-brand` component selectors and English-specific typography hooks, avoiding the earlier one-off `brand-banner` naming drift and duplicated title styles.
+
+## 0.25.2
+
+Released: 2026-04-10
+
+### Highlights
+
+- Refined the Earth HUD operator polish so settings now behave like a true bounded menu, HUD panels render at the correct scale from the first frame, and dragged panels animate cleanly into and out of maximized layout targets without drifting to screen edges.
+
+### Improved
+
+- Improved [frontend/public/earth/index.html](/home/ray/dev/linkong/planet/frontend/public/earth/index.html) by precomputing the initial `--hud-scale` before Earth CSS loads, so HUD panels no longer flash at full size before shrinking to the target scale.
+- Improved [frontend/public/earth/css/hud.css](/home/ray/dev/linkong/planet/frontend/public/earth/css/hud.css) by cleaning up duplicated settings-modal close-button styles, aligning the settings title with the shared HUD title system, and constraining the settings sheet to a stable centered width instead of viewport-relative modal sizing.
+
+### Fixed
+
+- Fixed [frontend/public/earth/js/controls.js](/home/ray/dev/linkong/planet/frontend/public/earth/js/controls.js) so dragged HUD panels now fly from their dragged positions into maximized layout targets, closed panels stay out of the transition, and restoring layout clears drag overrides back to the initial positions.
+- Fixed [frontend/public/earth/js/controls.js](/home/ray/dev/linkong/planet/frontend/public/earth/js/controls.js) and [frontend/public/earth/css/hud.css](/home/ray/dev/linkong/planet/frontend/public/earth/css/hud.css) so layout transitions no longer visibly stick to screen edges before landing; the FLIP motion now composes with the existing corner transforms instead of fighting them.
+
+## 0.25.1
+
+Released: 2026-04-10
+
+### Highlights
+
+- Cleaned up the first persistent Playground rollout, fixed sidebar submenu persistence to match the intended operator behavior, and added reusable code-hygiene rules to prevent this class of drift from accumulating again.
+
+### Improved
+
+- Improved [backend/app/services/playground_chat_service.py](/home/ray/dev/linkong/planet/backend/app/services/playground_chat_service.py) and [frontend/src/pages/Playground/Playground.tsx](/home/ray/dev/linkong/planet/frontend/src/pages/Playground/Playground.tsx) by extracting repeated lookup, response, and request-action paths into shared helpers, reducing duplicated Playground flow code without changing behavior.
+- Improved [rules.md](/home/ray/dev/linkong/planet/rules.md) by adding a new `Code Hygiene - MANDATORY` section covering single-source-of-truth state, transitional cleanup, repeated-logic extraction, layout debugging order, and post-feature cleanup expectations.
+
+### Fixed
+
+- Fixed [frontend/src/components/AppLayout/AppLayout.tsx](/home/ray/dev/linkong/planet/frontend/src/components/AppLayout/AppLayout.tsx) so first-level menu expansion now behaves correctly across in-app navigation: `采集与数据` remains the default expanded group after refresh, while manually expanded groups stay open when navigating to their own child routes and reset only on page reload.
+
+## 0.25.0
+
+Released: 2026-04-10
+
+### Highlights
+
+- Turned `AI Playground` into a persistent backend-backed chat workspace, added dedicated alert workspaces as a foundation for future situational analysis, and aligned the operator UI around a more structured AI + alerts workflow instead of one-off playground calls.
+
+### Added
+
+- Added [backend/app/models/playground_session.py](/home/ray/dev/linkong/planet/backend/app/models/playground_session.py), [backend/app/models/playground_message.py](/home/ray/dev/linkong/planet/backend/app/models/playground_message.py), and [backend/app/services/playground_chat_service.py](/home/ray/dev/linkong/planet/backend/app/services/playground_chat_service.py) so Playground conversations, execution state, edits, retries, and stop/resume semantics are persisted in the backend database rather than living only in browser state.
+- Added [backend/app/services/alert_ai_brief.py](/home/ray/dev/linkong/planet/backend/app/services/alert_ai_brief.py), [backend/app/services/situational_alert_ai_brief.py](/home/ray/dev/linkong/planet/backend/app/services/situational_alert_ai_brief.py), and the dedicated alert pages [frontend/src/pages/Alerts/SystemAlerts.tsx](/home/ray/dev/linkong/planet/frontend/src/pages/Alerts/SystemAlerts.tsx), [frontend/src/pages/Alerts/BGPAlerts.tsx](/home/ray/dev/linkong/planet/frontend/src/pages/Alerts/BGPAlerts.tsx), and [frontend/src/pages/Alerts/SituationalAlerts.tsx](/home/ray/dev/linkong/planet/frontend/src/pages/Alerts/SituationalAlerts.tsx) to establish the alert-analysis foundation for later situational awareness expansion.
+
+### Improved
+
+- Improved [frontend/src/pages/Playground/Playground.tsx](/home/ray/dev/linkong/planet/frontend/src/pages/Playground/Playground.tsx) and [frontend/src/index.css](/home/ray/dev/linkong/planet/frontend/src/index.css) by rebuilding Playground into a true chatbox workflow with persistent history, edit-and-resend behavior, grounded message actions, responsive composer behavior, bottom-stick scrolling, and tighter mobile layout handling.
+- Improved [frontend/src/components/AppLayout/AppLayout.tsx](/home/ray/dev/linkong/planet/frontend/src/components/AppLayout/AppLayout.tsx), [frontend/src/App.tsx](/home/ray/dev/linkong/planet/frontend/src/App.tsx), and [frontend/src/pages/Alerts/Alerts.tsx](/home/ray/dev/linkong/planet/frontend/src/pages/Alerts/Alerts.tsx) by reorganizing navigation around `采集与数据`, `专题观测`, and split alert entries so the app can scale to more observability and situational modules without turning the top-level UI into a single overloaded page.
+- Improved [README.md](/home/ray/dev/linkong/planet/README.md) and [docs/agents/situational-awareness-foundation-plan.md](/home/ray/dev/linkong/planet/docs/plans/agents-situational-awareness-foundation-plan.md) by documenting the current AI/alerts base, planned situational-awareness direction, and the new persistent Playground foundation.
+
+### Fixed
+
+- Fixed [backend/app/services/playground_chat_service.py](/home/ray/dev/linkong/planet/backend/app/services/playground_chat_service.py) so background Playground runs explicitly commit state transitions, allowing frontend polling to observe real pending/thinking/answering/done states instead of seeing stale empty threads.
+- Fixed [frontend/src/services/situational-awareness/index.ts](/home/ray/dev/linkong/planet/frontend/src/services/situational-awareness/index.ts) by removing the temporary mock gateway path, so Playground and alert-related AI flows now reflect the real backend/provider chain instead of local fake responses.
+
+## 0.24.8
+
+Released: 2026-04-10
+
+### Highlights
+
+- Refined the BGP AI brief operator workflow so the tab now stays compact and metadata-focused, while the full Markdown brief opens in a bounded modal that respects the repo’s single-screen layout rules.
+
+### Improved
+
+- Improved [frontend/src/pages/BGP/BGP.tsx](/home/ray/dev/linkong/planet/frontend/src/pages/BGP/BGP.tsx) by turning the brief action row into a clearer `历史简报下拉框 + 查看 + 生成` flow, keeping inline metadata visible in the tab while moving full Markdown reading into a dedicated modal workspace.
+
+### Fixed
+
+- Fixed [frontend/src/index.css](/home/ray/dev/linkong/planet/frontend/src/index.css) and [frontend/src/pages/BGP/BGP.tsx](/home/ray/dev/linkong/planet/frontend/src/pages/BGP/BGP.tsx) so the BGP brief modal no longer spills below the viewport; long brief content now scrolls inside the modal body instead of extending past the visible screen.
+
+## 0.24.7
+
+Released: 2026-04-10
+
+### Highlights
+
+- Formalized repository release hygiene and frontend layout guardrails so repeated versioning chores and recurring layout regressions now have explicit repo-level rules instead of living only in conversation context.
+
+### Added
+
+- Added [release-workflow/SKILL.md](/home/ray/dev/linkong/planet/.codex/skills/release-workflow/SKILL.md), defining the repository release workflow for version bumps, changelog/version-history updates, minimal validation, and commit/push sequencing.
+
+### Improved
+
+- Improved [rules.md](/home/ray/dev/linkong/planet/rules.md) by adding mandatory release-workflow requirements and a new frontend layout constraint section covering single-screen workspaces, overflow ownership, tab-pane behavior, compact-mode expectations, and readable-card fallbacks.
+- Improved [frontend-layout-guidelines.md](/home/ray/dev/linkong/planet/docs/technical/frontend-layout-guidelines.md) by summarizing the recurring Earth, Playground, BGP, and admin-layout regressions into concrete constraints for future frontend work, including “prefer scrollbars over unreadable compression” and “do not treat every tab as a table pane.”
+
+## 0.24.6
+
+Released: 2026-04-10
+
+### Highlights
+
+- Tightened several backend hot paths outside the original BGP page fixes, stabilized BGP collector coverage after the recent query refactors, and rebuilt the BGP AI brief tab so saved Markdown briefs render and scroll like a proper operator workspace instead of collapsing inside the shared table layout.
+
+### Improved
+
+- Improved [backend/app/api/v1/datasources.py](/home/ray/dev/linkong/planet/backend/app/api/v1/datasources.py) by replacing per-datasource task, count, and endpoint lookups with batched prefetch helpers, reducing the worst `1 + N` behavior on the datasource list and `trigger-all` flow.
+- Improved [backend/app/api/v1/visualization.py](/home/ray/dev/linkong/planet/backend/app/api/v1/visualization.py) by switching the main Earth-facing `CollectedData` endpoints to `is_current` records, batching multi-source loads for aggregate endpoints, and removing stale Python-side dedupe paths from the hot route.
+- Improved [backend/app/services/bgp_incidents.py](/home/ray/dev/linkong/planet/backend/app/services/bgp_incidents.py) and [backend/app/services/bgp_enrichment.py](/home/ray/dev/linkong/planet/backend/app/services/bgp_enrichment.py) by avoiding historical full-table infrastructure scans, narrowing observation baseline payloads to required columns, and pushing more ASN filtering into the database.
+- Improved [backend/app/api/v1/alerts.py](/home/ray/dev/linkong/planet/backend/app/api/v1/alerts.py), [backend/app/api/v1/dashboard.py](/home/ray/dev/linkong/planet/backend/app/api/v1/dashboard.py), and [backend/app/api/v1/settings.py](/home/ray/dev/linkong/planet/backend/app/api/v1/settings.py) by collapsing several repeated count and settings queries into fewer aggregate or batched reads.
+- Improved [frontend/src/pages/BGP/BGP.tsx](/home/ray/dev/linkong/planet/frontend/src/pages/BGP/BGP.tsx), [frontend/src/index.css](/home/ray/dev/linkong/planet/frontend/src/index.css), and [frontend/src/components/MarkdownRenderer/MarkdownRenderer.tsx](/home/ray/dev/linkong/planet/frontend/src/components/MarkdownRenderer/MarkdownRenderer.tsx) by rebuilding the `AI 简报` tab layout, fixing saved brief scrolling behavior, and extending the renderer to handle tables, separators, and stored metadata comments more gracefully.
+- Improved [docs/frontend/plans/ai-playground-development-plan.md](/home/ray/dev/linkong/planet/docs/plans/frontend-ai-playground-development-plan.md) by explicitly recording that the current BGP brief is only the first-stage summary flow and that regional prefix-geography analysis remains a planned Phase B follow-up.
+
+### Fixed
+
+- Fixed [backend/app/services/bgp_collectors.py](/home/ray/dev/linkong/planet/backend/app/services/bgp_collectors.py) and [backend/app/services/bgp_enrichment.py](/home/ray/dev/linkong/planet/backend/app/services/bgp_enrichment.py) so JSON field extraction no longer depends on the less portable `.astext` path that could break BGP collector endpoints in local environments.
+- Fixed the BGP AI brief tab in [frontend/src/index.css](/home/ray/dev/linkong/planet/frontend/src/index.css) and [frontend/src/pages/BGP/BGP.tsx](/home/ray/dev/linkong/planet/frontend/src/pages/BGP/BGP.tsx) so long saved briefs are no longer compressed into a tiny clipped viewport by the shared tab/table overflow rules.
+
+## 0.24.4
+
+Released: 2026-04-09
+
+### Highlights
+
+- Refined the `planet.sh` AI Provider rebuild UX so image rebuilds now feel like first-class scripted tasks, with clearer stage boundaries and cleaner fallback messaging instead of leaking raw Compose output into the terminal.
+
+### Improved
+
+- Improved [planet.sh](/home/ray/dev/linkong/planet/planet.sh) by keeping AI Provider image build logs in a temporary file, surfacing stage-specific detail copy for `docker compose v2` and `docker-compose v1`, and showing an explicit success line when the image rebuild finishes before container health checks begin.
+
+### Fixed
+
+- Fixed [planet.sh](/home/ray/dev/linkong/planet/planet.sh) so the AI Provider image rebuild stage no longer dumps raw Compose build output into the main spinner flow during normal successful runs.
+- Fixed [planet.sh](/home/ray/dev/linkong/planet/planet.sh) so the `构建 AI Provider 镜像` phase now ends with an explicit completion signal instead of visually blending into the subsequent container health-check phase.
+
+## 0.24.3
+
+Released: 2026-04-09
+
+### Highlights
+
+- Extended `AI Playground` from a minimal prompt form into a more repeatable diagnostics workspace, and hardened `planet.sh` so AI Provider restarts can rebuild changed images and expose clearer Compose fallback behavior.
+
+### Improved
+
+- Improved [frontend/src/pages/Playground/Playground.tsx](/home/ray/dev/linkong/planet/frontend/src/pages/Playground/Playground.tsx) by adding preset scenarios, response metadata, `thinking` block visibility, raw JSON inspection, and copy actions so the page works more like a proper AI diagnostics console.
+- Improved [frontend/src/index.css](/home/ray/dev/linkong/planet/frontend/src/index.css) by styling Playground presets, result metadata, raw response sections, and responsive action groups without breaking the single-screen workspace layout.
+- Improved [planet.sh](/home/ray/dev/linkong/planet/planet.sh) so AI Provider restarts detect code/config changes, rebuild the image when needed, and surface which Compose path is being used during image and container operations.
+
+### Fixed
+
+- Fixed the AI Provider restart path in [planet.sh](/home/ray/dev/linkong/planet/planet.sh) so code changes inside `aiprovider/` no longer stay hidden behind an old container image after `restart -a`.
+- Fixed Compose error reporting in [planet.sh](/home/ray/dev/linkong/planet/planet.sh) by making the script explicitly show `docker compose v2` first, then `docker-compose v1`, and only fail after both execution paths are exhausted.
+
+## 0.24.2
+
+Released: 2026-04-09
+
+### Highlights
+
+- Fixed the public-entry and AI diagnostics regressions introduced during the recent frontend routing and playground work, while also reducing the main frontend bundle by switching to route-level lazy loading and more targeted vendor chunking.
+
+### Improved
+
+- Improved [frontend/src/App.tsx](/home/ray/dev/linkong/planet/frontend/src/App.tsx) by lazy-loading admin pages and large workspaces through `React.lazy()` plus `Suspense`, so the initial frontend entry no longer pulls every route into the first bundle.
+- Improved [frontend/vite.config.ts](/home/ray/dev/linkong/planet/frontend/vite.config.ts) by adding targeted manual chunking for React, icon, network, and Earth-related vendor dependencies instead of leaving everything in one monolithic application bundle.
+- Improved [frontend/src/index.css](/home/ray/dev/linkong/planet/frontend/src/index.css) by adding a shared route-loading state and making the Playground help panel size to its content instead of stretching to fill the sidebar.
+
+### Fixed
+
+- Fixed [frontend/src/App.tsx](/home/ray/dev/linkong/planet/frontend/src/App.tsx) so anonymous visits to `/` once again reach the public Earth entry through the existing `/ -> /earth` redirect instead of being intercepted by the login screen.
+- Fixed [frontend/src/pages/Playground/Playground.tsx](/home/ray/dev/linkong/planet/frontend/src/pages/Playground/Playground.tsx) so cached provider status is shown immediately but still refreshed from the backend, avoiding stale diagnostics after `.env` or provider changes within the same browser tab.
+- Fixed [frontend/src/pages/Playground/Playground.tsx](/home/ray/dev/linkong/planet/frontend/src/pages/Playground/Playground.tsx) and [frontend/src/index.css](/home/ray/dev/linkong/planet/frontend/src/index.css) so the `测试说明` card no longer over-expands and now fits its content more naturally in the sidebar.
+
+## 0.24.1
+
+Released: 2026-04-09
+
+### Highlights
+
+- Refined the `/earth` HUD into a cleaner class-first structure with responsive scaling, clearer CSS layer boundaries, and lower coupling between HTML, CSS, and runtime UI updates.
+- Hardened local startup conventions around Bun so frontend tooling, docs, and `planet.sh` behave more predictably in fresh Ubuntu and mixed WSL environments.
+
+### Added
+
+- Added [frontend/public/earth/css/hud.css](/home/ray/dev/linkong/planet/frontend/public/earth/css/hud.css), extracting shared HUD panel surfaces, shared HUD typography rows, status messaging, tooltip overlays, and layout-expanded panel transitions out of the old monolithic base layer.
+- Added [frontend/public/earth/css/toolbar.css](/home/ray/dev/linkong/planet/frontend/public/earth/css/toolbar.css), isolating Earth toolbar, popover, zoom dock, liquid-glass button, and toolbar-tooltip behavior into a dedicated toolbar layer.
+- Added explicit Bun package-manager metadata to [frontend/package.json](/home/ray/dev/linkong/planet/frontend/package.json) so the frontend package manager choice is declared instead of inferred from the lockfile alone.
+
+### Improved
+
+- Improved [frontend/public/earth/css/base.css](/home/ray/dev/linkong/planet/frontend/public/earth/css/base.css) by reducing it to app-shell concerns only: global tokens, Earth app container, loading panel, and shared animation primitives.
+- Improved [frontend/public/earth/index.html](/home/ray/dev/linkong/planet/frontend/public/earth/index.html) by wiring the new CSS layer order, standardizing HUD utility classes on `hud-panel-*`, and replacing generic toolbar/tooltip hooks with more explicit Earth-specific classes.
+- Improved [frontend/public/earth/css/info-panel.css](/home/ray/dev/linkong/planet/frontend/public/earth/css/info-panel.css), [frontend/public/earth/css/coordinates-display.css](/home/ray/dev/linkong/planet/frontend/public/earth/css/coordinates-display.css), [frontend/public/earth/css/legend.css](/home/ray/dev/linkong/planet/frontend/public/earth/css/legend.css), and [frontend/public/earth/css/earth-stats.css](/home/ray/dev/linkong/planet/frontend/public/earth/css/earth-stats.css) by leaving only panel-specific responsibilities in each file after the shared HUD and toolbar primitives moved out.
+- Improved [frontend/public/earth/js/main.js](/home/ray/dev/linkong/planet/frontend/public/earth/js/main.js), [frontend/public/earth/js/controls.js](/home/ray/dev/linkong/planet/frontend/public/earth/js/controls.js), [frontend/public/earth/js/ui.js](/home/ray/dev/linkong/planet/frontend/public/earth/js/ui.js), and [frontend/public/earth/js/legend.js](/home/ray/dev/linkong/planet/frontend/public/earth/js/legend.js) by aligning runtime DOM queries and generated markup with the new class-first HUD and toolbar structure.
+- Improved [frontend/public/earth/js/constants.js](/home/ray/dev/linkong/planet/frontend/public/earth/js/constants.js) and [frontend/public/earth/js/main.js](/home/ray/dev/linkong/planet/frontend/public/earth/js/main.js) by keeping HUD scaling configurable through extracted constants instead of scattering scaling assumptions through the main Earth entrypoint.
+- Improved [planet.sh](/home/ray/dev/linkong/planet/planet.sh) by prepending `~/.local/bin` and `~/.bun/bin` automatically, preferring direct `~/.bun/bin/bun` detection, and auto-installing missing `uv`/`bun` instead of requiring the user's interactive shell config to expose them first.
+- Improved [README.md](/home/ray/dev/linkong/planet/README.md), [project_context.md](/home/ray/dev/linkong/planet/project_context.md), [rules.md](/home/ray/dev/linkong/planet/rules.md), and [scripts/bootstrap-dev.sh](/home/ray/dev/linkong/planet/scripts/bootstrap-dev.sh) by making the frontend Bun-only workflow explicit in both onboarding docs and command-line guidance.
+
+### Fixed
+
+- Fixed the Earth HUD cleanup path where splitting styles previously left the page with a missing `base.css` entry and mismatched utility class names during the refactor.
+- Fixed several Earth UI update paths so toolbar tooltip text, legend re-rendering, status message classes, and mouse coordinate styling continue to work after removing legacy fallback selectors.
+- Fixed the local developer bootstrap path where `planet.sh start` could fail in a clean Ubuntu or agent shell session simply because Bun or uv were installed outside the current shell's inherited `PATH`.
+
+## 0.24.0
+
+Released: 2026-04-09
+
+### Highlights
+
+- Added a dedicated `AI Playground` admin entry so operators can validate provider connectivity and run controlled situational-analysis prompts from the main frontend without introducing a separate UI service.
+- Established a first explicit frontend layout rulebook centered on single-screen workspaces, internal module scrolling, and BGP-style page composition for future admin pages.
+
+### Added
+
+- Added [frontend/src/pages/Playground/Playground.tsx](/home/ray/dev/linkong/planet/frontend/src/pages/Playground/Playground.tsx), introducing the first dedicated AI testing workspace with provider status visibility, prompt/result tabs, and collapsible operator guidance.
+- Added [docs/frontend/technical/frontend-layout-guidelines.md](/home/ray/dev/linkong/planet/docs/technical/frontend-layout-guidelines.md), documenting the repository standard for one-screen admin workspaces and module-local overflow handling.
+- Added [docs/frontend/plans/ai-playground-development-plan.md](/home/ray/dev/linkong/planet/docs/plans/frontend-ai-playground-development-plan.md), capturing the completed AI gateway/UI work and the next delivery phases for BGP briefs, evidence-first inputs, and future agent runtime expansion.
+
+### Improved
+
+- Improved [frontend/src/components/AppLayout/AppLayout.tsx](/home/ray/dev/linkong/planet/frontend/src/components/AppLayout/AppLayout.tsx) and [frontend/src/App.tsx](/home/ray/dev/linkong/planet/frontend/src/App.tsx) by wiring `AI Playground` into the main admin navigation and route tree instead of pointing operators to a nonexistent `aiprovider` chat page.
+- Improved [planet.sh](/home/ray/dev/linkong/planet/planet.sh) by replacing the incorrect `localhost:8010/chat` closeout link with the frontend `AI Playground` entry.
+- Improved [docker-compose.yml](/home/ray/dev/linkong/planet/docker-compose.yml) by attaching `./aiprovider/.env` to the `aiprovider` service so provider identity, model, and credentials actually reach the running container.
+- Improved [README.md](/home/ray/dev/linkong/planet/README.md) by linking the new frontend layout guidance and AI Playground development plan.
+- Improved [frontend/src/index.css](/home/ray/dev/linkong/planet/frontend/src/index.css) by refining the Playground workspace into a notebook-friendly left-sidebar plus right-tabbed layout, reusing thin scrollbars, and making provider/help/result regions degrade more gracefully under constrained height.
+
+### Fixed
+
+- Fixed the local AI status flow so provider configuration no longer appeared permanently `disabled / not configured` merely because `aiprovider/.env` was not mounted into the container.
+- Fixed repeated `Provider 状态` refetching when switching away from and back to `/playground` by caching the last known provider status within the browser session until the operator explicitly refreshes it.
+- Fixed several Playground layout regressions where auxiliary panels could push the result area out of view or clip provider details without exposing internal scrolling.
+
+## 0.23.4
+
+Released: 2026-04-08
+
+### Highlights
+
+- Fixed the BGP overview workspace so summary cards and tabular data now share viewport space more predictably, keeping the table header visible while preserving internal horizontal and vertical scrolling.
+
+### Improved
+
+- Improved [BGP.tsx](/home/ray/dev/linkong/planet/frontend/src/pages/BGP/BGP.tsx) by switching BGP tables from frontend pagination to in-table scrolling, setting explicit horizontal scroll baselines per tab, and reshaping the summary cards into a desktop two-row layout with a compact single-row horizontal strip on tighter screens.
+- Improved [index.css](/home/ray/dev/linkong/planet/frontend/src/index.css) by hardening the BGP table layout chain from card body to Ant Design table body, so width overflow stays inside the table region and compact summary cards no longer consume unnecessary vertical space above the workspace.
+- Improved release consistency by aligning [VERSION](/home/ray/dev/linkong/planet/VERSION), [pyproject.toml](/home/ray/dev/linkong/planet/pyproject.toml), [frontend/package.json](/home/ray/dev/linkong/planet/frontend/package.json), and [uv.lock](/home/ray/dev/linkong/planet/uv.lock) on the same `0.23.4` bugfix version.
+
+### Fixed
+
+- Fixed the BGP collector/events tables so shrinking the browser window no longer clips the table card frame without exposing a usable horizontal scrollbar.
+- Fixed the BGP table region so the Ant Design header row is no longer obscured by an overgrown table body after the page switched to full-height internal scrolling.
+- Fixed the BGP summary area so medium and large screens no longer collapse the six KPI cards into overly narrow single-row tiles.
+
+## 0.23.3
+
+Released: 2026-04-08
+
+### Highlights
+
+- Refined `planet.sh` startup and restart presentation so service bring-up, health checks, and frontend dev-server readiness are easier to follow in real time.
+
+### Improved
+
+- Improved [planet.sh](/home/ray/dev/linkong/planet/planet.sh) by standardizing the script on `zsh`, tightening frontend startup stage rendering, and making spinner-driven subtask feedback show up step by step instead of bunching at the end.
+- Improved [planet.sh](/home/ray/dev/linkong/planet/planet.sh) by clarifying health-check subtask copy, filtering noisy frontend startup lines, and aligning terminal output spacing across spinner and status rows.
+
+### Fixed
+
+- Fixed several `zsh` compatibility issues in [planet.sh](/home/ray/dev/linkong/planet/planet.sh), including reserved variable name collisions during `restart` and container health checks.
+- Fixed [planet.sh](/home/ray/dev/linkong/planet/planet.sh) so frontend readiness animation no longer appears frozen while waiting for Vite startup and health probes.
+
+## 0.23.2
+
+Released: 2026-04-08
+
+### Highlights
+
+- Hardened datasource retrigger handling so operators can safely force reruns without losing control of task state visibility or rollback behavior.
+
+### Improved
+
+- Improved [frontend/src/pages/DataSources/DataSources.tsx](/home/ray/dev/linkong/planet/frontend/src/pages/DataSources/DataSources.tsx) by mapping phase-local task percentages into a continuous overall progress bar, pre-checking running task status before retriggering, and consolidating the trigger/force-confirm flow.
+- Improved [planet.sh](/home/ray/dev/linkong/planet/planet.sh) by polishing startup CLI output, reducing duplicated spinner cleanup, and standardizing log/help output around the newer terminal presentation.
+
+### Fixed
+
+- Fixed forced datasource reruns in [backend/app/services/collectors/base.py](/home/ray/dev/linkong/planet/backend/app/services/collectors/base.py) by rolling back invalid SQLAlchemy session state before marking cancelled or failed task cleanup, preventing `PendingRollbackError` during operator-triggered cancellation.
+- Fixed datasource trigger UX in [frontend/src/pages/DataSources/DataSources.tsx](/home/ray/dev/linkong/planet/frontend/src/pages/DataSources/DataSources.tsx) so batch and single-source progress no longer jump straight to `100%` on frontend-side status coercion while the backend is still reporting real progress.
+
+## 0.23.1
+
+Released: 2026-04-07
+
+### Highlights
+
+- Fixed the BGP overview page so high-DPI and lower-height screens can keep the observation workspace visible within a single viewport.
+
+### Improved
+
+- Improved [BGP.tsx](/home/ray/dev/linkong/planet/frontend/src/pages/BGP/BGP.tsx) by switching the page to a height-aware shell, compact summary layout, and tabbed data workspace so observation tables retain the majority of the screen.
+- Improved [index.css](/home/ray/dev/linkong/planet/frontend/src/index.css) by adding responsive BGP-specific compact spacing, denser table paddings, and an internal scroll region for collector coverage and event tables.
+
+### Fixed
+
+- Fixed the BGP observation page on small or high-scale displays where stacked stats and full-height blocks consumed too much vertical space, leaving only a couple of visible table rows.
+

+# Earth 电视直播模块计划
+
+## 目标
+
+为 `Earth` 页面增加一个可配置、可扩展、可拖拽的电视直播模块：
+
+- 后台可配置新闻直播源
+- 默认兜底源为央视 `CCTV-4`
+- 未来可通过采集器接入世界各地新闻直播源
+- Earth 工具栏 `显示控制` 子菜单新增电视按钮

+
+## 设计原则
+
+- 第一阶段先交付“后台可配 + Earth 可用 + 默认可回退”的版本
+- 公开读取接口与后台管理接口分离
+- 手工配置源与采集器源共用统一的前端消费结构
+- Earth 里的电视窗口必须复用现有 HUD 拖拽、关闭、布局最大化逻辑
+- 小屏下优先保证窗口完整显示，超出部分在窗口内部滚动
+
+## 分阶段实现
+
+### Phase 1：后端配置与公开读取
+
+- 在系统设置中新增 `tv` 分类
+- 定义直播源配置结构：
+  - `default_source_id`
+  - `auto_fallback`
+  - `sources[]`
+- 每个直播源至少包含：
+  - `id`
+  - `name`
+  - `provider`

+
+### Phase 2：采集器扩展位
+
+- 新增 `news_live_streams` collector 占位
+- 规范采集器入库数据结构，使其能与后台手工配置源合并
+- TV 公开接口支持合并：
+  - 后台手工配置源
+  - 采集器入库源
+- 保持手工配置源优先级更高，避免采集器覆盖人工兜底配置
+
+### Phase 3：后台配置界面
+
+- 在系统配置页新增 `电视直播` tab
+- 支持：
+  - 查看当前默认源
+  - 开关自动回退
+  - 新增直播源
+  - 编辑直播源
+  - 删除直播源
+  - 启用/禁用直播源
+  - 将某个直播源设为默认源
+- 明确区分：
+  - 手工配置源
+  - 采集器来源
+
+### Phase 4：Earth HUD 集成
+
+- 在 `显示控制` 子菜单加入电视按钮
+- 新增 TV HUD 面板：
+  - 可拖拽
+  - 可关闭
+  - 支持显示/隐藏状态同步
+  - 参与布局最大化与恢复布局
+- 面板内容至少包含：
+  - 当前频道标题
+  - 源切换下拉菜单
+  - 刷新按钮
+  - 打开官网按钮
+  - 播放区域
+
+### Phase 5：播放策略
+
+- 第一版优先支持 `iframe`/嵌入页类直播源
+- 为未来扩展保留：
+  - `hls`
+  - `video`
+  - `external`
+- 如果默认源不可用：
+  - 优先回退到标记为 `is_fallback=true` 的源
+  - 若无明确回退源，则回退到第一个可用源
+- 面板内要有清晰的加载、错误、回退提示
+
+### Phase 6：打磨与清理
+
+- 统一 HUD 风格
+- 小屏下限制窗口尺寸并启用内部滚动
+- 避免窗口超出屏幕
+- 补最小验证
+- 清理临时代码、重复样式和无用资源
+
+## 首版交付定义
+
+当以下条件满足时，认为首版可用：
+
+- 后台可以配置新闻直播源
+- Earth 可以读取并显示默认直播源
+- 工具栏可打开电视窗口
+- 电视窗口可拖拽、可关闭
+- 央视 `CCTV-4` 作为默认兜底源可被使用
+- 代码结构已为后续采集器接入预留统一接口

+# HUD Panel Component Plan
+
+## Goal
+
+Unify Earth HUD panels into a reusable component layer so new panels can share:
+
+- a consistent shell
+- a consistent header
+- a consistent action-button system
+- a consistent body and collapse pattern
+
+## Scope
+
+Target panels:
+
+- `tv-panel`
+- `news-panel`
+- `legend`
+- `layer-panel`
+- `earth-stats`
+- `info-card`
+- settings modal header/actions
+
+## Component Model
+
+### Base shell
+
+- `.hud-panel`
+- `.hud-panel--compact`
+- `.hud-panel--media`
+- `.hud-panel--collapsed`
+- `.hud-panel-hidden`
+- `.hud-panel.is-dragging`
+- `.hud-panel.is-layout-animating`
+
+### Header
+
+- `.hud-panel__header`
+- `.hud-panel__title-group`
+- `.hud-panel__title`
+- `.hud-panel__subtitle`
+- `.hud-panel__chip`
+- `.hud-panel__actions`
+
+Header baseline rule:
+
+- Header title styling is fixed by the component layer and should not drift per panel
+- Title font size, font weight, letter spacing, line height, text color, and vertical alignment come from the shared header tokens and structure
+- Header divider, border treatment, inner spacing, and title-to-actions alignment are part of the same shared baseline
+- Panel-specific header differences should be limited to explicit variants such as `compact` or `media`, or token overrides with documented intent
+- “Looks close enough” local header overrides should be treated as temporary compatibility code and removed during migration
+
+### Actions
+
+- `.hud-panel__action`
+- `.hud-panel__action--icon`
+- `.hud-panel__action--collapse`
+- `.hud-panel__action--close`
+- `.hud-panel__action--refresh`
+- `.hud-panel__action--external`
+
+Action-button baseline rule:
+
+- Header action buttons must have one fixed default style baseline across all HUD panels
+- Default width behavior, padding, icon size, radius, alignment, hover, and active feedback all come from `.hud-panel__action`
+- Panel-specific differences must be expressed through explicit variants or token overrides, not ad-hoc local button rewrites
+- `close` buttons are part of the same default action system and must not silently fall back to a separate legacy box model
+
+### Body
+
+- `.hud-panel__body`
+- `.hud-panel__body--scroll`
+- `.hud-panel__body--collapsible`
+
+### Collapse behavior
+
+- `.hud-panel--collapsed`
+- `.hud-panel--expand-up`
+- `.hud-panel--expand-down`
+
+Adaptive collapse / expand rule:
+
+- HUD panels support two expansion directions:
+  - top-to-bottom expansion
+  - bottom-to-top expansion
+- Expansion direction should be decided at runtime from available viewport space rather than hardcoded per panel
+- Use:
+  - `d` = available distance from the header anchor to the viewport bottom edge
+  - `h` = expected expanded panel height
+  - buffer = `20px`
+- Collapsed-state direction rule:
+  - if `d > h + 20px`, the next action direction is `expand-up`
+  - if `d <= h + 20px`, the next action direction is `expand-down`
+- To avoid jitter around the threshold, the shared controller should keep a small hysteresis band:
+  - if the current direction is already `up`, keep it until `d <= h`
+  - if the current direction is already `down`, keep it until `d > h + 20px`
+- The opposite edge is still a safety guard:
+  - if the chosen side cannot fit at all, fall back to the other side if it can fit
+  - if neither side fully fits, choose the side with more space and let the body scroll
+- If neither direction fully fits, choose the direction with more available space and let the body scroll
+- Collapse icon direction must match the active expansion direction so the icon always describes the real open/close motion
+- The collapse icon describes the next action, not the current state
+- This mapping is fixed component behavior and must not drift per panel:
+  - collapsed + expand-down => `expand_more`
+  - expanded + expand-down => `expand_less`
+  - collapsed + expand-up => `expand_less`
+  - expanded + expand-up => `expand_more`
+- Panels must not combine icon-name swapping with extra CSS rotation for the same collapse control
+- Expansion direction and icon direction must come from one shared source of truth in the component controller
+- The direction decision should be recomputed when opening, resizing the viewport, or restoring a dragged panel near another edge
+
+## Tokens
+
+Promote panel differences into CSS variables instead of duplicating selectors:
+
+- `--hud-panel-padding`
+- `--hud-header-padding`
+- `--hud-header-gap`
+- `--hud-action-padding`
+- `--hud-action-gap`
+- `--hud-action-icon-size`
+- `--hud-body-gap`
+- `--hud-body-max-height`
+- `--hud-chip-radius`
+- `--hud-title-font-size`
+- `--hud-title-font-weight`
+- `--hud-title-letter-spacing`
+- `--hud-title-line-height`
+- `--hud-title-color`
+- `--hud-header-border-color`
+- `--hud-header-divider-opacity`
+- `--hud-expand-direction`
+
+## Migration Order
+
+1. Build the shared component layer in `frontend/public/earth/css/hud.css`
+2. Migrate `tv-panel` and `news-panel` first as the reference implementation
+3. Migrate `legend` and `layer-panel` into a compact variant
+4. Migrate `earth-stats` and `info-card`
+5. Align settings modal header/actions with the same action system
+6. Remove legacy one-off button selectors after verification
+
+## Guardrails
+
+- Do not change panel behavior and data flow during the first pass
+- Keep old class names temporarily as compatibility hooks
+- Prefer variable overrides over per-panel reimplementation
+- Treat header action-button default styling as fixed component API, not per-panel design space
+- Treat header title typography, border, and divider styling as fixed component API, not per-panel design space
+- Treat collapse direction as a component behavior contract, not a one-off panel trick
+- Treat collapse icon semantics as a component behavior contract, not a per-panel visual preference
+- Verify header alignment and drag/collapse behavior after each migration batch
+
+## First Implementation Batch
+
+Batch 1 should only do:
+
+- shared header structure
+- shared action-button system
+- shared title typography and header border/divider baseline
+- shared collapsible body pattern
+- adaptive collapse direction logic and direction-aware collapse icons
+- migration of `tv-panel` and `news-panel`
+
+That keeps risk low while giving the rest of the HUD a stable target to migrate toward.

+# Agent Architecture Plan
+
+## Overview
+
+This document defines the agent architecture for Planet.
+
+The architecture is intentionally broader than datasource health checking.
+
+It is designed to support both:
+
+- datasource health governance
+- future situational-awareness workflows
+
+The core idea is to avoid building a one-off "repair broken API links" agent.
+
+Instead, Planet should grow a reusable agent runtime that can:
+
+- collect evidence
+- evaluate signals
+- reason over incomplete information
+- generate proposals
+- produce assessments
+- execute limited actions under policy
+
+
+## Design Goal
+
+Build an agent foundation that can evolve in this order:
+
+1. datasource health checks
+2. datasource repair proposals
+3. signal correlation
+4. situational assessments
+5. controlled runtime actions
+
+This means the architecture should treat datasource health as one use case of the larger agent system, not as the whole system.
+
+
+## Core Principles
+
+1. Separate evidence from reasoning
+
+- raw signals should be gathered first
+- deterministic checks should run before LLM reasoning
+
+2. Agents do not own the defaults
+
+- repository defaults remain human-owned
+- agents operate on runtime state, proposals, and overrides
+
+3. Reasoning and action are different responsibilities
+
+- many agents should be read-only or propose-only
+- only tightly controlled flows may apply changes
+
+4. Shared runtime, specialized roles
+
+- multiple agent roles should share the same object model and orchestration patterns
+- health and situational-awareness agents should not invent incompatible payloads
+
+5. Auditability is mandatory
+
+- every proposal, assessment, and applied action should be attributable
+
+
+## System Layers
+
+Planet agent architecture should be split into four layers.
+
+### 1. Signal Layer
+
+Purpose:
+
+- gather raw evidence from internal and external systems
+
+Example sources:
+
+- collector outputs
+- datasource health checks
+- logs
+- snapshots
+- alerts
+- web search results
+- scraped pages
+- external APIs
+- operator inputs
+
+Responsibilities:
+
+- fetch
+- normalize
+- timestamp
+- tag with source and trust level
+
+This layer should not make high-level judgments.
+
+
+### 2. Evaluation Layer
+
+Purpose:
+
+- perform deterministic analysis
+
+Examples:
+
+- reachability checks
+- schema validation
+- threshold checks
+- time-window comparisons
+- anomaly counters
+- completeness checks
+
+Responsibilities:
+
+- classify signals into machine-readable findings
+- attach deterministic evidence
+
+This layer should avoid LLM dependency whenever possible.
+
+
+### 3. Reasoning Layer
+
+Purpose:
+
+- use LLMs when semantic interpretation or incomplete-information reasoning is needed
+
+Examples:
+
+- endpoint migration inference
+- multi-source event correlation
+- causality hypotheses
+- ambiguity reduction
+- assessment narrative generation
+- action recommendation generation
+
+Responsibilities:
+
+- synthesize evidence
+- produce hypotheses
+- rank confidence
+- explain reasoning boundaries
+
+This is the main place where `aiprovider` and web search are used.
+
+
+### 4. Action Layer
+
+Purpose:
+
+- convert proposals or assessments into controlled system actions
+
+Examples:
+
+- create runtime override
+- create proposal
+- publish alert
+- update operator task queue
+- generate summary artifact
+- trigger follow-up verification
+
+Responsibilities:
+
+- enforce policy
+- enforce approval requirements
+- verify post-action outcomes
+- record audit trails
+

+
+
+## Agent Roles
+
+The first version should define these logical roles.
+
+### 1. Health Agent
+
+Primary use case:
+
+- datasource health governance
+
+Inputs:
+
+- datasource metadata
+- current endpoint
+- latest health records
+- latest failures
+- deterministic findings
+
+Outputs:
+
+- health interpretation
+- repair proposal
+- confidence
+- evidence references
+
+Typical action level:
+
+- propose-only
+
+
+### 2. Correlation Agent
+
+Primary use case:
+
+- identify whether multiple signals describe the same event or related events
+
+Inputs:
+
+- findings from multiple collectors
+- time windows
+- region / ASN / prefix / cable relationships
+- prior incidents
+
+Outputs:
+
+- grouped event candidates
+- correlation rationale
+- confidence per relationship
+
+Typical action level:
+
+- read-only
+
+
+### 3. Assessment Agent
+
+Primary use case:
+
+- produce situational-awareness outputs
+
+Inputs:
+
+- grouped events
+- findings
+- current context
+- historical context
+- operator constraints
+
+Outputs:
+
+- structured assessment
+- risk summary
+- evidence-backed recommendations
+- missing-information list
+
+Typical action level:
+
+- read-only or propose-only
+
+
+### 4. Recovery Agent
+
+Primary use case:
+
+- carry low-risk proposals into controlled runtime actions
+
+Inputs:
+
+- approved proposal
+- policy constraints
+- trusted-domain rules
+- verification checks
+
+Outputs:
+
+- applied override
+- failed application
+- rollback request
+
+Typical action level:
+
+- apply-limited
+
+
+## Shared Object Model
+
+All agents should work on a shared object model.
+
+That prevents the health subsystem and situational-awareness subsystem from drifting into incompatible payloads.
+
+### Signal
+
+Represents a raw observed fact.
+
+Examples:
+
+- a datasource returned HTTP 404
+- a collector returned empty results
+- BGP updates spiked in one region
+- a known endpoint now redirects elsewhere
+
+Suggested shape:
+
+```json
+{
+  "id": "sig_123",
+  "type": "datasource.http_failure",
+  "source": "ris_live_bgp",
+  "occurred_at": "2026-04-08T10:00:00Z",
+  "severity": "medium",
+  "payload": {},
+  "trust": 0.95
+}
+```
+
+
+### Finding
+
+Represents a deterministic or semi-deterministic interpretation of one or more signals.
+
+Examples:
+
+- `schema_changed`
+- `endpoint_unreachable`
+- `data_volume_abnormally_low`
+- `event_cluster_detected`
+
+Suggested shape:
+
+```json
+{
+  "id": "find_123",
+  "type": "datasource.schema_changed",
+  "source_ids": ["sig_123"],
+  "confidence": 0.92,
+  "evidence": [],
+  "details": {}
+}
+```
+
+
+### Proposal
+
+Represents a recommended action, not an already-applied action.
+
+Examples:
+
+- switch endpoint to new URL
+- disable bad override
+- escalate issue for manual review
+
+Suggested shape:
+
+```json
+{
+  "id": "prop_123",
+  "kind": "endpoint_override",
+  "target": "telegeography_cables",
+  "confidence": 0.84,
+  "reason": "Official docs now point to a new API path",
+  "payload": {},
+  "evidence_urls": [],
+  "status": "proposed"
+}
+```
+
+
+### Assessment
+
+Represents a structured situational-awareness output for operators or downstream systems.
+
+Examples:
+
+- current network posture summary
+- incident impact assessment
+- risk and response recommendations
+
+Suggested shape:
+
+```json
+{
+  "id": "assess_123",
+  "scope": "regional-network",
+  "risk_level": "high",
+  "summary": "Regional routing instability is increasing.",
+  "key_risks": [],
+  "evidence": [],
+  "recommendations": [],
+  "missing_data": []
+}
+```
+
+
+## State Machine
+
+The shared orchestration flow should look like this:
+
+```mermaid
+stateDiagram-v2
+    [*] --> Collect
+    Collect --> Validate
+    Validate --> Classify
+    Classify --> Reason
+    Reason --> Propose
+    Reason --> Assess
+    Propose --> Review
+    Review --> Apply
+    Apply --> Verify
+    Verify --> Archive
+    Assess --> Archive
+    Archive --> [*]
+```
+
+Definitions:
+
+- `Collect`: gather signals
+- `Validate`: run deterministic checks
+- `Classify`: create findings
+- `Reason`: invoke LLM reasoning when needed
+- `Propose`: create change proposals
+- `Review`: policy or human approval
+- `Apply`: perform limited runtime action
+- `Verify`: confirm action effect
+- `Archive`: store artifacts and decisions
+
+
+## Permission Model
+
+Each agent role should be assigned one of these action levels.
+
+### `read-only`
+
+Allowed:
+
+- read signals
+- search web
+- fetch pages
+- read internal state
+- generate findings and assessments
+
+Not allowed:
+
+- mutate config
+- write overrides
+- change live runtime behavior
+
+
+### `propose-only`
+
+Allowed:
+
+- everything in `read-only`
+- create proposals
+- create review tasks
+
+Not allowed:
+
+- apply live changes
+
+
+### `apply-limited`
+
+Allowed:
+
+- everything in `propose-only`
+- write approved runtime overrides
+- trigger verification checks
+
+Not allowed:
+
+- mutate repository defaults
+- make destructive data changes
+- bypass policy engine
+
+
+## Runtime Components
+
+The first durable architecture should introduce these components.
+
+### 1. Signal Store
+
+Stores normalized evidence and health outputs.
+
+
+### 2. Finding Store
+
+Stores deterministic classifications that can be reused by multiple agents.
+
+
+### 3. Proposal Store
+
+Stores recommended actions with evidence and confidence.
+
+
+### 4. Assessment Store
+
+Stores structured situational-awareness outputs.
+
+
+### 5. Policy Engine
+
+Decides:
+
+- whether agent may run
+- whether proposal requires review
+- whether proposal may auto-apply
+- whether post-apply verification passed
+
+
+### 6. Override Store
+
+Stores runtime-only configuration changes.
+
+This is where endpoint repairs should live.
+
+
+## Relation To `aiprovider`
+
+`aiprovider` should remain the model gateway.
+
+It should not become the full agent runtime.
+
+Recommended split:
+
+- `aiprovider`
+  - provider adaptation
+  - prompt transport
+  - model execution
+  - protocol compatibility
+
+- agent runtime
+  - orchestration
+  - signal handling
+  - tool selection
+  - proposal generation
+  - policy and audit
+
+This keeps provider concerns and agent behavior concerns separate.
+
+
+## Relation To Datasource Health
+
+Datasource health becomes one vertical slice of this architecture.
+
+Mapping:
+
+- signal:
+  - endpoint unreachable
+  - schema mismatch
+  - bad content type
+- finding:
+  - `failed`
+  - `schema_changed`
+  - `moved_endpoint_suspected`
+- proposal:
+  - runtime override suggestion
+- assessment:
+  - datasource health summary for operators
+
+
+## Relation To Situational Awareness
+
+Future situational-awareness capabilities should reuse the same flow:
+
+- raw telemetry becomes signals
+- anomaly detection becomes findings
+- LLM correlation becomes reasoning
+- operator-facing output becomes assessments
+- policy-approved mitigations become actions
+
+This lets the platform evolve from operational health governance into broader cyber/network posture workflows without changing the architecture.
+
+
+## Suggested Delivery Sequence
+
+### Phase A
+
+- finalize shared object model
+- implement health-oriented signal and finding storage
+
+### Phase B
+
+- implement Health Agent
+- generate proposals only
+
+### Phase C
+
+- implement Assessment Agent
+- expose structured assessments via API
+
+### Phase D
+
+- implement Correlation Agent
+- support multi-source incident grouping
+
+### Phase E
+
+- implement Recovery Agent with policy-gated runtime actions
+
+
+## Recommended First Build
+
+The first build should not try to implement every agent role.
+
+Recommended initial slice:
+
+- shared object model
+- health signals
+- health findings
+- Health Agent
+- proposal generation only
+
+This gives immediate value while preserving the longer-term architecture.
+
+
+## Non-Goals For The First Iteration
+
+- repository YAML auto-rewrites
+- unrestricted autonomous action
+- full incident graph reasoning
+- automatic large-scale remediation
+- agent-owned configuration source of truth
+
+
+## Summary
+
+Planet should treat agents as a reusable runtime for evidence, reasoning, proposals, and assessments.
+
+The datasource health use case is the first practical entrypoint, but the architecture should already assume future situational-awareness expansion.
+
+The safest path is:
+
+- deterministic checks first
+- agent reasoning second
+- proposals before actions
+- runtime overrides instead of default mutation

+# Agent Runtime Roadmap
+
+## Overview
+
+This document connects three existing planning threads into one implementation roadmap:
+
+- `aiprovider` as the model gateway
+- datasource health governance as the first practical agent use case
+- situational awareness as the broader long-term target
+
+Related documents:

+- [agent-architecture-plan](/home/ray/dev/linkong/planet/docs/plans/agents-agent-architecture-plan.md)
+
+
+## Big Picture
+
+Planet should evolve in layers:
+
+1. stable model gateway
+2. deterministic health and evidence collection
+3. agent runtime for reasoning and proposal generation
+4. situational-awareness assessments and controlled actions
+
+This prevents the system from collapsing into a single giant "AI feature" with unclear boundaries.

+
+
+## Role Boundaries
+
+### `aiprovider`
+
+Responsibilities:
+
+- provider compatibility
+- protocol adaptation
+- auth and model transport
+- request/response normalization
+
+Not responsible for:
+
+- agent orchestration
+- business workflows
+- datasource repair policy
+- situational-awareness domain logic
+
+
+### Backend
+
+Responsibilities:
+
+- stable business APIs
+- auth and permissions
+- task orchestration
+- health records
+- proposal and override persistence
+- assessment exposure
+
+
+### Agent Runtime
+
+Responsibilities:
+
+- consume findings and context
+- invoke LLMs via `aiprovider`
+- invoke tools such as web search
+- create proposals
+- create assessments
+- route to policy-controlled action paths
+
+
+## Delivery Sequence
+
+## Stage 1: Gateway Foundation
+
+Status:
+
+- already in place
+
+Delivered by current work:
+
+- `aiprovider`
+- multi-provider compatibility
+- backend AI facade
+- MiniMax / Anthropic-compatible support
+- request-id propagation
+
+Primary outcome:
+
+- the system already has a stable way to call models
+
+
+## Stage 2: Datasource Health MVP
+
+Goal:
+
+- establish deterministic health observability
+
+Key work:
+
+- health check task runner
+- health result table
+- datasource health APIs
+- UI visibility
+- collector endpoint override precedence cleanup
+
+Primary outcome:
+
+- Planet knows which collectors are healthy before asking an LLM anything
+
+
+## Stage 3: Health Agent
+
+Goal:
+
+- let the first agent role operate on health failures
+
+Key work:
+
+- convert health failures into signals/findings
+- invoke agent only for failed or suspicious cases
+- produce repair proposals with evidence and confidence
+
+Primary outcome:
+
+- Planet can suggest endpoint repairs without mutating defaults
+
+
+## Stage 4: Runtime Repair Application
+
+Goal:
+
+- safely apply approved datasource repair proposals
+
+Key work:
+
+- override storage
+- policy-gated apply flow
+- verification after apply
+- rollback path
+
+Primary outcome:
+
+- datasource repair becomes operationally useful without polluting repository defaults
+
+
+## Stage 5: Situational Awareness Assessments
+
+Goal:
+
+- reuse the same runtime for broader operator-facing assessment
+
+Key work:
+
+- normalize telemetry and incident evidence into signals/findings
+- build Assessment Agent
+- expose structured assessments through backend APIs and UI
+
+Primary outcome:
+
+- LLM output becomes evidence-backed situational summary, not just ad hoc chat output
+
+
+## Stage 6: Correlation and Controlled Actions
+
+Goal:
+
+- connect multiple sources into higher-level posture and event groupings
+
+Key work:
+
+- event correlation
+- incident grouping
+- recommendation scoring
+- controlled action routing
+
+Primary outcome:
+
+- Planet becomes a true agent-assisted situational-awareness system
+
+
+## Implementation Tracks
+
+These tracks can progress in parallel, but they should stay loosely coupled.
+
+### Track A: Config and Runtime Resolution
+
+Scope:
+
+- datasource defaults
+- overrides
+- runtime precedence
+- audit trails
+
+First milestone:
+
+- health-safe override layer
+
+
+### Track B: Health and Evidence
+
+Scope:
+
+- deterministic checks
+- failure categorization
+- signal and finding persistence
+
+First milestone:
+
+- datasource health record system
+
+
+### Track C: Agent Runtime
+
+Scope:
+
+- shared object model
+- orchestration flow
+- prompt/tool pipeline
+- policy integration
+
+First milestone:
+
+- Health Agent proposal pipeline
+
+
+### Track D: Situational Awareness
+
+Scope:
+
+- assessment schema
+- multi-source context assembly
+- operator-facing outputs
+
+First milestone:
+
+- structured assessment API
+
+
+## Shared Artifacts
+
+To avoid fragmentation, these artifacts should be shared across all future agent work.
+
+### Shared object model
+
+- `Signal`
+- `Finding`
+- `Proposal`
+- `Assessment`
+
+### Shared orchestration flow
+
+- collect
+- validate
+- classify
+- reason
+- propose or assess
+- review or apply
+- verify
+- archive
+
+### Shared policy model
+
+- read-only
+- propose-only
+- apply-limited
+
+
+## Recommended Next Concrete Steps
+
+1. Build Stage 2 first
+
+- datasource health records
+- deterministic checks
+- no automatic repair
+
+2. Then build Stage 3
+
+- Health Agent
+- proposal generation only
+
+3. Then Stage 4
+
+- override apply flow
+- rollback and verification
+
+4. Only after that start Stage 5
+
+- broader situational-awareness assessment workflows
+
+
+## Why This Order
+
+Because situational-awareness quality depends on reliable upstream data.
+
+If datasource health is weak:
+
+- agent reasoning quality will degrade
+- false explanations will increase
+- assessment trust will drop
+
+So datasource health is not a side task.
+
+It is the first operational foundation for the later situational-awareness system.
+
+
+## Summary
+
+Planet should be built as:
+
+- `aiprovider` for model access
+- backend services for orchestration and persistence
+- datasource health as the first evidence-governance layer
+- agent runtime as the reusable reasoning core
+- situational awareness as the long-term application layer
+
+That path keeps the architecture coherent and lets each phase produce useful functionality without forcing a rewrite later.

+# Datasource Health Plan
+
+## Overview
+
+This document defines a phased plan for datasource health governance.
+
+The goal is to make collectors observable, diagnosable, and recoverable when upstream APIs change, while avoiding unsafe automatic mutation of repository defaults.
+
+The key principle is:
+
+- do not let runtime automation rewrite repository default config
+
+Instead, split responsibilities across:
+
+- default config
+- runtime overrides
+- health check records
+- agent-generated repair proposals
+
+
+## Problem Statement
+
+Collectors currently depend on third-party APIs, data downloads, mirrored JSON files, archive links, and web pages.
+
+These upstream dependencies can fail in several ways:
+
+- endpoint becomes unreachable
+- endpoint still responds but schema changes
+- content-type changes
+- website shuts down or moves
+- mirror link disappears
+- HTML structure changes and scraping fails
+- endpoint requires a new path or new host
+
+We want a system that can:
+
+- detect datasource health degradation early
+- identify likely cause
+- search for updated endpoints when reasonable
+- apply safe runtime fixes without polluting default repo config
+- preserve auditability and rollback
+
+
+## Design Principles
+
+1. Default config is stable
+
+- `backend/app/core/data_sources.yaml` remains the repository baseline.
+- It should be changed intentionally through normal development flow, not by autonomous runtime agents.
+
+2. Runtime fixes are isolated
+
+- Emergency or adaptive fixes should live in a runtime override layer.
+- Overrides should be reversible and auditable.
+
+3. Deterministic checks come first
+
+- Use normal programmatic health checks before using LLMs.
+- Only call an agent when deterministic checks indicate a meaningful failure.
+
+4. Agents suggest before they mutate
+
+- Agents should produce proposals with evidence and confidence.
+- Application of a proposal should be controlled by policy.
+
+5. Every repair is attributable
+
+- Store what changed, why, who or what suggested it, and when it was applied.
+
+
+## Configuration Layers
+
+Recommended runtime precedence:
+
+1. datasource endpoint override
+2. datasource DB endpoint override
+3. repository default YAML
+4. collector internal fallback logic
+
+Definitions:
+
+- repository default YAML:
+  - `backend/app/core/data_sources.yaml`
+  - versioned baseline
+- datasource DB endpoint override:
+  - existing `DataSourceConfig.endpoint`
+  - current runtime override entrypoint
+- datasource endpoint override:
+  - a dedicated new override table
+  - used for health-repair and proposal application
+- collector internal fallback logic:
+  - final defensive fallback
+  - should be minimized over time
+
+
+## Recommended Architecture
+
+### 1. Deterministic Health Checks
+
+Each collector gets a health profile with checks such as:
+
+- endpoint resolves
+- HTTP request succeeds
+- status code is acceptable
+- content-type is expected
+- body parses successfully
+- minimum structural fields exist
+- sample item count is plausible
+- latency is within threshold
+
+Output states:
+
+- `healthy`
+- `degraded`
+- `failed`
+- `schema_changed`
+- `rate_limited`
+- `auth_required`
+
+
+### 2. Agent-Assisted Repair Discovery
+
+Only triggered when deterministic health checks fail or return suspicious structure.
+
+Agent responsibilities:
+
+- search for current official endpoint or replacement path
+- inspect likely upstream documentation or landing pages
+- compare candidate endpoint output to collector expectations
+- produce a repair proposal with confidence and evidence
+
+Agent should not directly modify repository defaults.
+
+
+### 3. Safe Runtime Repair Application
+
+Repair proposals can be:
+
+- reviewed manually
+- auto-applied only under strict low-risk policy
+
+Auto-apply should be limited to cases like:
+
+- same trusted domain
+- highly similar response structure
+- repeated successful verification
+- confidence above threshold
+
+
+## Phased Delivery Plan
+
+## Phase 1: Deterministic Health MVP
+
+Goal:
+
+- build health observability without automated repair
+
+Scope:
+
+- datasource health check task runner
+- datasource health result persistence
+- endpoint reachability + parse checks
+- dashboard or API visibility into health status
+
+Deliverables:
+
+- health check service
+- health check record table
+- status endpoint
+- scheduled or manual check trigger
+
+No agent usage yet.
+
+
+## Phase 2: Agent Repair Proposals
+
+Goal:
+
+- let agent investigate failing sources and propose updated endpoints
+
+Scope:
+
+- invoke agent only when datasource health is `failed` or `schema_changed`
+- web search + page inspection
+- candidate endpoint extraction
+- proposal persistence
+
+Deliverables:
+
+- repair proposal schema
+- proposal generation pipeline
+- confidence and evidence model
+- operator review view or API
+
+Still no automatic config mutation.
+
+
+## Phase 3: Runtime Overrides
+
+Goal:
+
+- allow approved proposals to take effect safely at runtime
+
+Scope:
+
+- add dedicated override storage
+- runtime resolution prefers override over default config
+- proposal application writes override only
+
+Deliverables:
+
+- endpoint override table
+- override-aware resolution logic
+- apply/reject endpoints
+- rollback endpoint
+
+Repository default YAML remains untouched.
+
+
+## Phase 4: Limited Auto-Apply
+
+Goal:

+
+
+## Agent Contract Draft
+
+When deterministic health fails, the agent should receive:
+
+- datasource name
+- collector name
+- current endpoint
+- current failure mode
+- expected response shape summary
+- known trusted domains
+
+Expected output:
+
+```json
+{
+  "status": "proposal",
+  "candidate_endpoint": "https://example.com/api/v2/data",
+  "confidence": 0.86,
+  "reason": "Official docs now point to v2 endpoint",
+  "evidence_urls": [
+    "https://example.com/docs/api",
+    "https://example.com/changelog"
+  ],
+  "notes": "Response shape appears compatible after light field remapping"
+}
+```
+
+The agent should never output "rewrite the default yaml" as its primary action.
+
+
+## Risk Analysis
+
+### Risk: wrong endpoint chosen by agent
+
+Mitigation:
+
+- use trusted-domain allowlists
+- require evidence URLs
+- require confidence threshold
+- add manual review for medium-risk sources
+
+
+### Risk: endpoint responds but schema silently changed
+
+Mitigation:
+
+- deterministic schema checks
+- parse and sample validation
+- content-type checks
+- collector-specific required fields
+
+
+### Risk: automatic runtime override causes hidden drift
+
+Mitigation:
+
+- store all overrides explicitly
+- mark source of override
+- keep default YAML unchanged
+- expose active overrides in API/UI
+
+
+### Risk: persistent bad override breaks data collection
+
+Mitigation:
+
+- allow rollback
+- keep parent/default endpoint visible
+- re-run verification after apply
+- auto-disable override on repeated failure
+
+
+## Operational Policy Recommendations
+
+1. Do not auto-apply for high-value or high-fragility sources initially.
+
+2. Use manual approval for:
+
+- scraped HTML sources
+- unofficial mirrors
+- sources with auth or rate-limit complexity
+- sources with legal or trust ambiguity
+
+3. Allow auto-apply only for:
+
+- same-domain version bumps
+- obvious official migration paths
+- repeated passing verification
+
+4. Expose health + proposal + override state together in one operator view.
+
+
+## Suggested Implementation Order
+
+1. Phase 1
+- health result table
+- deterministic checks
+- API and UI visibility
+
+2. Phase 2
+- proposal table
+- agent prompt/output contract
+- proposal generation job
+
+3. Phase 3
+- runtime override table
+- resolver precedence update
+- apply/reject endpoints
+
+4. Phase 4
+- auto-apply rules
+- rollback policy
+- operator automation
+
+
+## Out Of Scope For The First Iteration
+
+- direct automatic mutation of repository default YAML
+- automatic git commits by repair agents
+- unrestricted autonomous endpoint replacement
+- fully generalized schema remapping engine
+
+
+## Recommended First Milestone
+
+The first milestone should be:
+
+- deterministic datasource health checks
+- persisted results
+- manual visibility
+- no automatic repair
+
+This gives immediate operational value with low risk, and prepares clean inputs for the later agent phase.

+# Datasource Health Stage 2 Tasks
+
+## Goal
+
+Stage 2 focuses on the first practical operational layer:
+
+- deterministic datasource health checks
+- persisted health results
+- health visibility through API and UI
+- no agent-assisted repair yet
+
+This stage should make Planet capable of answering:
+
+- which collectors are healthy
+- which collectors are degraded
+- which collectors are failing
+- why they are failing at a basic deterministic level
+
+
+## Scope
+
+Included:
+
+- datasource health data model
+- deterministic health check service
+- manual and scheduled health check triggers
+- health result APIs
+- frontend visibility
+
+Excluded:
+
+- LLM reasoning
+- web-search-based repair proposals
+- automatic endpoint rewriting
+- runtime override application
+
+
+## Delivery Target
+
+At the end of Stage 2, an operator should be able to:
+
+1. see health status for each collector
+2. trigger a health check manually
+3. inspect the latest failure reason
+4. inspect the last checked endpoint
+5. understand whether the problem is:
+   - unreachable
+   - auth-related
+   - rate-limit-related
+   - schema-related
+   - empty-data-related
+
+
+## Work Breakdown
+
+## A. Data Model
+
+### A1. Add datasource health record table
+
+Create a new model, for example:
+
+- `backend/app/models/datasource_health_check.py`
+
+Suggested fields:
+
+- `id`
+- `datasource_id`
+- `collector_name`
+- `endpoint_checked`
+- `status`
+- `http_status`
+- `content_type`
+- `latency_ms`
+- `sample_count`
+- `error_message`
+- `details`
+- `checked_at`
+
+Suggested status enum values:
+
+- `healthy`
+- `degraded`
+- `failed`
+- `schema_changed`
+- `rate_limited`
+- `auth_required`
+- `empty_result`
+
+
+### A2. Add datasource health summary fields
+
+Option A:
+
+- keep summary only in the health check table
+
+Option B:
+
+- also add summary fields on `data_sources`
+
+Recommended first step:
+
+- do not mutate `data_sources` schema yet
+- derive summary from the latest health record
+
+
+### A3. Migration task
+
+Add migration for the health table.
+
+Deliverables:
+
+- migration file
+- model registration
+
+
+## B. Health Check Engine
+
+### B1. Define health check service
+
+Add a new service module, for example:
+
+- `backend/app/services/datasource_health.py`
+
+Responsibilities:
+
+- resolve effective endpoint
+- execute deterministic check
+- classify result
+- persist health record
+
+
+### B2. Define shared result schema
+
+Create a typed result object, for example:
+
+- `HealthCheckResult`
+
+Suggested fields:
+
+- `status`
+- `endpoint_checked`
+- `http_status`
+- `content_type`
+- `latency_ms`
+- `sample_count`
+- `error_message`
+- `details`
+
+
+### B3. Implement base deterministic checks
+
+Every datasource should go through a minimal baseline check:
+
+1. resolve endpoint
+2. perform request
+3. measure latency
+4. inspect status code
+5. inspect content type
+6. inspect body shape
+
+Classification rules:
+
+- network error -> `failed`
+- HTTP 401/403 -> `auth_required`
+- HTTP 429 -> `rate_limited`
+- HTTP 404/410 -> `failed`
+- parse failure -> `schema_changed`
+- zero or suspiciously empty results -> `empty_result` or `degraded`
+- valid parse -> `healthy`
+
+
+### B4. Add collector-aware adapters
+
+Some collectors do not use the same fetch semantics.
+
+Add adapter profiles such as:
+
+- `http_json`
+- `http_csv`
+- `html_scrape`
+- `stream_probe`
+- `auth_session_http`
+
+Initial mapping suggestion:
+
+- `huggingface`, `peeringdb`, `cloudflare` -> `http_json`
+- `fao` -> `http_csv`
+- `top500`, `epoch_ai`, `telegeography live_map` -> `html_scrape`
+- `ris_live` -> `stream_probe`
+- `spacetrack` -> `auth_session_http`
+
+
+### B5. Add sample validation hooks
+
+For each adapter, add a lightweight validation rule.
+
+Examples:
+
+- JSON array length > 0
+- CSV rows > 1
+- HTML page contains expected table or script patterns
+- stream source yields at least one valid event within timeout
+
+
+## C. Persistence and Query Layer
+
+### C1. Save every check run
+
+Each health check should insert a record.
+
+Do not overwrite history in Stage 2.
+
+
+### C2. Add latest-health query helpers
+
+Add helper functions to fetch:
+
+- latest health record by datasource
+- latest failed health record
+- recent health history
+
+
+### C3. Optional retention policy
+
+For Stage 2, retention can be deferred.
+
+If desired, keep only:
+
+- last N records per datasource
+
+
+## D. API Layer
+
+### D1. Add health list endpoint
+
+Suggested endpoint:
+
+- `GET /api/v1/datasources/health`
+
+Returns:
+
+- datasource id
+- collector name
+- current endpoint
+- latest health status
+- last checked time
+- short reason
+
+
+### D2. Add per-datasource health detail endpoint
+
+Suggested endpoint:
+
+- `GET /api/v1/datasources/{id}/health`
+
+Returns:
+
+- latest record
+- recent history
+- detailed classification fields
+
+
+### D3. Add manual health trigger endpoint
+
+Suggested endpoint:
+
+- `POST /api/v1/datasources/{id}/health-check`
+
+Behavior:
+
+- run a health check now
+- persist the result
+- return the new record
+
+
+### D4. Add bulk health trigger endpoint
+
+Suggested endpoint:
+
+- `POST /api/v1/datasources/health-check-all`
+
+Behavior:
+
+- enqueue or run health checks for all active datasources
+
+
+## E. Scheduling
+
+### E1. Add health scheduler task
+
+Decide scheduling strategy.
+
+Recommended first version:
+
+- run collector jobs and health checks separately
+- health checks run on a lower frequency
+
+Suggested frequency:
+
+- every 6h or 12h for most datasources
+- optionally on-demand only in the very first cut
+
+
+### E2. Prevent health check collision with collection
+
+Rules:
+
+- health checks should not disrupt active collection
+- they should use light requests
+- if a collector is currently running, health check may:
+  - skip
+  - or use a lightweight endpoint probe only
+
+
+## F. Frontend
+
+### F1. Add health columns to datasource list
+
+Update:
+
+- `frontend/src/pages/DataSources/DataSources.tsx`
+
+Suggested new columns:
+
+- health status
+- last checked
+- reason summary
+
+
+### F2. Add manual health check action
+
+Per datasource:
+
+- button or dropdown action:
+  - `健康检查`
+
+
+### F3. Add health detail drawer or modal
+
+Show:
+
+- endpoint checked
+- status
+- HTTP status
+- content type
+- sample count
+- error message
+- last few results
+
+
+### F4. Add basic visual language
+
+Suggested colors:
+
+- green -> healthy
+- yellow -> degraded
+- orange -> rate-limited / auth-required
+- red -> failed / schema-changed
+
+
+## G. Observability
+
+### G1. Structured logging
+
+Every health check should log:
+
+- datasource id
+- collector name
+- endpoint
+- status
+- latency
+- failure class
+
+
+### G2. Optional metrics
+
+If metrics are added later, useful counters include:
+
+- health checks total
+- health checks failed
+- schema changes detected
+- rate limited checks
+
+
+## H. Tests
+
+### H1. Unit tests
+
+Add tests for:
+
+- status classification
+- content type classification
+- adapter behavior
+- latest-health query helpers
+
+
+### H2. API tests
+
+Add tests for:
+
+- health endpoints require auth
+- manual trigger endpoint works
+- list endpoint returns latest status
+
+
+### H3. Failure-path tests
+
+Add coverage for:
+
+- HTTP 404
+- HTTP 429
+- invalid JSON
+- empty response
+- parse mismatch
+
+
+## Suggested File Plan
+
+Possible implementation files:
+
+- `backend/app/models/datasource_health_check.py`
+- `backend/app/services/datasource_health.py`
+- `backend/app/schemas/datasource_health.py`
+- `backend/app/api/v1/datasource_health.py`
+- migration file under the project migration system
+
+Likely touched existing files:
+
+- `backend/app/api/main.py`
+- `frontend/src/pages/DataSources/DataSources.tsx`
+- `backend/tests/test_api.py`
+
+
+## Suggested Execution Order
+
+1. Add model and migration
+2. Add service and result schema
+3. Add deterministic adapters
+4. Add manual trigger API
+5. Add list/detail API
+6. Add frontend visibility
+7. Add scheduled checks
+8. Expand tests
+
+
+## Minimal First Milestone
+
+If we want the fastest useful slice, do this first:
+
+1. health table
+2. deterministic check service
+3. manual per-datasource health check API
+4. latest health list API
+5. frontend status badge column
+
+That is enough to start operating the system and will provide the input layer for Stage 3.
+
+
+## Dependency On Later Stages
+
+Stage 2 outputs become direct inputs for Stage 3.
+
+Specifically:
+
+- failed or schema-changed health records become agent triggers
+- health history becomes repair context
+- endpoint_checked becomes proposal baseline
+
+
+## Success Criteria
+
+Stage 2 is done when:
+
+- every active datasource can be health-checked deterministically
+- the latest health state is visible in API and UI
+- operators can manually trigger checks
+- failures are categorized into stable machine-readable statuses
+- no LLM is required for core health visibility

+# Situational Awareness Foundation Plan
+
+## 定位
+
+当前这套 AI 能力应被视为 `态势感知服务底座`，而不是完整的态势感知产品。
+
+也就是说，现阶段的目标不是：
+
+- 做一个“什么都能分析”的万能 AI 页面
+- 让模型在证据不足时替代人工研判
+- 过早把页面做成完整指挥大屏
+
+现阶段真正要做的是：
+
+- 先把 `model gateway / backend facade / evidence injection / page-specific brief` 这几层边界搭稳
+- 让系统能够在已有证据上稳定地产出“可读、可回看、可扩展”的摘要
+- 为后续更强的数据联动、agent 推理和 assessment 结构化输出预留好接口与数据模型
+
+## 当前现实约束
+
+### 1. 数据维度不足
+
+目前系统能提供的主要证据仍集中在：
+
+- BGP incidents / anomalies / events
+- collector coverage
+- datasource health / platform alerts
+- prefix geography 的部分归属信息
+
+当前明显还缺：
+
+- 流量异常与业务指标
+- 电商、支付、物流等业务侧指标
+- 更丰富的资产、链路、区域、行业画像
+- 外部舆情、公告、运营商状态、基础设施事件等背景信息
+
+这意味着：
+
+- 模型现在可以做“基于现有证据的摘要与归纳”
+- 但还不能可靠地做“跨维度因果研判”
+
+### 2. 维度之间联动还弱
+
+目前不同模块之间更多是“并列展示”，还不是“强关联分析”：
+
+- 系统告警和 BGP 事件还没有统一事件模型
+- collector bias 与真实区域热度还没有完全剥离
+- datasource health 与 BGP 风险、业务影响之间还没有稳定映射
+
+这意味着：
+
+- 当前更适合做 `brief / overview / operator notes`
+- 还不适合过度承诺“自动态势判断”
+
+### 3. 结构化 assessment 还未成为主输出
+
+虽然已经有 BGP brief、系统告警 brief、态势告警 brief，但目前主输出仍偏向：
+
+- 文本摘要
+- facts/context 附带证据
+
+后续真正要服务态势感知，需要更稳定的结构化输出，例如：
+
+- summary
+- key risks
+- evidence
+- confidence
+- recommendations
+- missing data
+
+## 当前基座已经具备的能力
+
+### 1. AI 调用边界已经明确
+
+- `aiprovider` 负责模型协议与 provider 兼容
+- `backend` 负责业务 API、证据整合和鉴权
+- `frontend` 负责页面入口与结果展示
+
+### 2. 页面级 AI 入口已经开始成型
+
+当前已经有或正在收口的入口：
+
+- `Playground`
+  - 用于链路验证与 provider 诊断
+- `BGP AI 简报`
+  - 用于 BGP 事实摘要和区域风险归纳
+- `Alerts`
+  - 用于系统告警、BGP 告警、态势告警三类入口
+
+### 3. 证据优先的方向已经建立
+
+已经不再只依赖人工在 Playground 中手填 prompt，系统开始具备：
+
+- 从真实业务数据生成事实输入
+- 保存 facts/context 快照
+- 回看 AI 输出时同时回看证据
+
+这一步非常关键，因为它决定后面能否从“玩具 demo”走向“有运维价值的系统”。
+
+## 近期收尾建议
+
+这些事情都属于“底座收口”，值得做，但不应该再继续重产品包装。
+
+### 1. 统一 Alerts 页面
+
+已采用：
+
+- 一个 `Alerts` 页面
+- 三个 tab：
+  - `系统告警`
+  - `BGP 告警`
+  - `态势告警`
+
+收尾重点：
+
+- 保持 tab 的文案、摘要卡和 AI 简报交互一致
+- 不额外扩展成多个独立二级页面
+
+### 2. 保持 Playground 为测试台
+
+原则：
+
+- Playground 只承担链路验证、provider 状态诊断、请求结果观察
+- 不继续堆“万能业务分析器”式交互
+
+### 3. 把 brief 能力当服务能力而不是页面特效
+
+页面现在能看到按钮和结果，这很好，但更重要的是：
+
+- 后端接口稳定
+- facts/context 可追踪
+- 输出结构后续可升级
+
+### 4. 导航结构先收口，不继续平铺一级菜单
+
+随着后续能力扩展，系统很可能继续新增：
+
+- 海缆
+- 算力中心
+- 战争信息
+- 电商分析
+- 其他专题观测页
+
+如果继续把这些入口全部平铺在左侧一级菜单中，会带来两个问题：
+
+- 一级菜单过长，用户难以判断先进入哪个上下文
+- `观测页 / 告警页 / 研判页 / 运维页` 的职责边界会被混在一起
+
+因此近期应明确采用分组导航，而不是继续扩展平铺菜单。
+
+推荐的导航分组如下：
+
+- `总览`
+  - 仪表盘
+  - Earth
+- `专题观测`
+  - BGP 观测
+  - 采集数据
+  - 后续可扩展：海缆、算力中心、战争信息、电商分析
+- `告警与研判`
+  - Alerts
+- `运维与配置`
+  - 数据源
+  - AI Playground
+  - 用户管理
+  - 系统配置
+
+这套结构的含义是：
+
+- `专题观测` 页面负责看某个维度本身
+- `Alerts` 负责跨模块风险与值班工作台
+- `Playground` 保持为测试台，不挤占业务导航语义
+
+短期收尾时，应优先重组现有入口，而不是继续增加新的一级菜单。
+
+## 后续路线
+
+## Phase 1：服务底座稳固
+
+目标：
+
+- 不追求“更炫的 AI 页面”
+- 先把当前接口、证据、存储和页面入口收稳
+
+工作项：
+
+- 统一页面级 AI 入口模式
+- 统一 brief response schema
+- 保证 facts/context 在前后端都可回看
+- 继续清理 mock 和临时分支逻辑
+
+完成标准：
+
+- 每个 AI 入口都是真实链路
+- 每个 AI 结果都能追溯到证据输入
+
+## Phase 2：Evidence-first Assessment
+
+目标：
+
+- 从“文本摘要”升级成“结构化 assessment”
+
+工作项：
+
+- 为 brief/assessment 定义统一 schema
+- 固化：
+  - summary
+  - key_risks
+  - evidence
+  - confidence
+  - recommendations
+  - missing_data
+- 页面以结构化区块展示，而不只是大段文本
+
+完成标准：
+
+- AI 输出可持久化、可比较、可审计
+
+## Phase 3：多维证据接入
+
+目标：
+
+- 让“态势感知”真正拥有更多维度，而不是只靠 BGP 与系统告警
+
+优先接入方向：
+
+- datasource health findings
+- 流量或业务指标
+- 区域/资产/链路映射
+- 外部事件与公告
+- 业务垂直数据，例如电商分析相关指标
+
+完成标准：
+
+- AI 能基于多个维度做交叉说明
+- 不再只围绕单一模块自说自话
+
+## Phase 4：Correlation Layer
+
+目标：
+
+- 不同来源的信号不再只是并列，而是形成统一的事件关联
+
+工作项：
+
+- 统一 signal/finding 模型
+- 跨模块事件聚合
+- 证据来源权重
+- collector bias 与真实热度分离
+
+完成标准：
+
+- 系统能回答“这些异常是不是同一件事”
+- 系统能回答“哪些结论只是观测偏差”
+
+## Phase 5：Agent-assisted Situational Awareness
+
+目标：
+
+- 在证据足够的前提下，再让 agent 负责更复杂的推理与建议
+
+工作项：
+
+- 复用现有 agent runtime 规划
+- 引入 web search / docs fetch / repair proposal 等能力
+- 但始终坚持：
+  - evidence first
+  - proposal before action
+  - no silent mutation of defaults
+
+完成标准：
+
+- agent 成为证据驱动的分析层
+- 而不是一个“万能猜测层”
+
+## 设计原则
+
+### 1. 先底座，后产品化
+
+先把服务链路和证据模型做好，再做更大的页面表达。
+
+### 2. 先证据，后判断
+
+事实输入应先稳定，再让模型做归纳。
+
+### 3. 先专用 brief，后统一态势层
+
+先让各业务页有各自可信的 AI 入口，再考虑统一态势页。
+
+### 4. 先 proposal，后自动动作
+
+涉及修复、覆盖、写配置、调任务的动作，都应经过 proposal 和审计。
+
+## 当前建议结论
+
+对现在这个项目，最合理的定位是：
+
+- `Playground` 是测试台
+- `BGP / Alerts` 是第一批业务 AI 入口
+- `aiprovider + backend AI facade + evidence snapshots` 是核心服务底座
+
+现阶段不需要追求“已经具备完整态势感知能力”。
+
+现阶段真正的成功标准是：
+
+- 这套底座可用
+- 可回看
+- 可扩展
+- 不自欺欺人

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

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

+# Earth Real Terrain Plan
+
+## Goal
+
+将 Earth 页当前的“程序噪声假地形”替换成基于真实 DEM 的可用地形层，使 `地形 terrain` 开关真正显示全球海拔起伏，而不是占位效果。
+
+当前占位实现位于：
+
+- [earth.js](/home/ray/dev/linkong/planet/frontend/public/earth/js/earth.js)
+
+具体问题：
+
+- `createTerrain()` 直接对球体顶点应用 `simplex noise`
+- 没有真实海拔数据来源
+- 没有分辨率分层
+- 没有和当前相机/视角配套的性能控制
+
+## Constraints
+
+本计划必须贴合当前 Earth 架构，而不是引入一套全新的地形引擎：
+
+- 地球主体仍然是一个 Three.js sphere
+- 海缆、登陆点、卫星、BGP 都已经建立在当前球体坐标系之上
+- 不能为了地形把整页改成 Cesium/MapLibre Globe 之类的全栈替换
+- 第一阶段优先做“真实可用”，不是一步到位做摄影测量级地形
+
+## Recommended Data Source
+
+### Primary recommendation
+
+使用公开的 Terrarium 编码高程瓦片作为浏览器端高度来源，第一阶段优先接入：
+
+- Mapzen/AWS `Terrarium` elevation tiles  
+  参考：[Mapzen terrain tile format / Terrarium](https://www.mapzen.com/blog/terrain-tile-service/)
+
+原因：
+
+- 已经是全球瓦片化高程
+- 浏览器端按 tile 请求，最适合当前 Earth 这种在线 globe
+- 编码简单稳定：
+  - `heightMeters = (R * 256 + G + B / 256) - 32768`
+- 不需要我们先离线拼整球 DEM
+
+### Data quality upgrade path
+
+如果后面第一阶段效果确认可用，再逐步升级到底层源：
+
+- Copernicus DEM GLO-30  
+  参考：[Copernicus DEM docs](https://documentation.dataspace.copernicus.eu/APIs/SentinelHub/Data/DEM.html)
+- 或用 Copernicus / SRTM / ASTER 等离线切成我们自己的 terrain tiles
+
+这条升级路径适合第二阶段，不建议一开始就直接自建全球瓦片服务。
+
+## Why Not Replace the Engine
+
+不建议为了地形直接切到 Cesium terrain / quantized mesh 引擎，原因：
+
+- 现有 Earth 业务对象都依附当前球面坐标
+- 切引擎会同时波及：
+  - 海缆绘制
+  - 卫星/轨迹
+  - BGP 标记
+  - HUD 与交互
+- 这是“重做一页”，不是“给地形层接真实数据”
+
+所以推荐路线是：
+
+- 保持当前 sphere globe
+- 为 sphere 增加真实高度位移层
+
+## Implementation Strategy
+
+分三期推进。
+
+### Phase 1 — Global Heightmap Terrain Overlay
+
+目标：
+
+- 地形层切换后显示真实海拔起伏
+- 全球范围可用
+- 性能可控
+
+做法：
+
+1. 新增 terrain 数据模块
+
+建议文件：
+
+- `frontend/public/earth/js/terrain.js`
+
+职责：
+
+- 选择 DEM zoom level
+- 请求 Terrarium tiles
+- 解码 tile 高程
+- 将高程重采样到当前地形球体网格
+
+2. 替换 `createTerrain()`
+
+当前：
+
+- 在 [earth.js](/home/ray/dev/linkong/planet/frontend/public/earth/js/earth.js) 中同步生成噪声地形
+
+调整后：
+
+- `createTerrain()` 只负责创建 terrain mesh 骨架
+- 真正的顶点位移由 terrain 模块异步注入
+
+3. 第一阶段采用“整球低分辨率位移”
+
+不要一上来做动态 patch stitching。第一阶段更稳的办法是：
+
+- 保留一张全球 terrain sphere
+- 使用较低分辨率几何
+  - 例如 `SphereGeometry(radius, 192, 192)` 或 `256/256`
+- 运行时按一个固定地形 zoom（如 `z=4` 或 `z=5`）抓取覆盖全球的 Terrarium tiles
+- 将 tile 解码后重投影到经纬度采样网格
+- 将每个球面顶点按真实高度抬升
+
+这样第一阶段就能做到：
+
+- 有真实地形
+- 不需要复杂的局部 LOD
+- 不会让现有球体对象体系爆炸
+
+### Phase 2 — View-Aware Refinement
+
+目标：
+
+- 正面可见区域更精细
+- 背面与远处维持低成本
+
+做法：
+
+- 引入“基础全球地形 + 当前视角高分局部补丁”
+- 正面区域额外抓更高 zoom 的高程 tile
+- 只替换局部顶点位移或局部 overlay mesh
+
+这一阶段适合在第一阶段稳定后做。
+
+### Phase 3 — Normals / Shading / Terrain UX
+
+目标：
+
+- 地形不仅有起伏，还更好看、更可读
+
+包括：
+
+- 根据高度生成更合理的 normals
+- 调整 terrain material，使山脉/高原更易读
+- 可选加入：
+  - hillshade
+  - contour lines
+- snowline / bathymetry tint
+
+## Calibration Overlay Before More Terrain Tuning
+
+在当前项目里，terrain 看起来“不像真地形”，不一定只是 DEM 或 exaggeration 不够，也可能是因为缺少稳定参照物。
+
+没有清晰的海岸线、国界线和地表分层时，人眼很难判断：
+
+- 山脉是不是在应该高的地方高
+- terrain 是否真的贴在正确的大陆位置上
+- 地球纹理、本初子午线、terrain 采样之间是否存在偏移
+
+这里要明确区分两件事：
+
+- 国界线不会修好错误的 terrain
+- 但海岸线 / 国界线会让我们更容易判断 terrain 有没有贴准
+
+所以在继续盲调 terrain 参数之前，建议先插入一个“校准参照层”阶段。
+
+### Recommended order for the calibration layer
+
+1. 海岸线
+2. 国界线
+3. 再继续调 terrain
+
+原因：
+
+- 海岸线比国界线更基础，也更接近真实地表边界
+- 判断 terrain 是否贴准，最重要的是大陆边缘和山脉/海岸关系
+- 国界线更多是政治边界，只能作为辅助参照
+
+如果只加国界线，不加海岸线，效果仍然可能会怪，因为：
+
+- 很多国界线本来就是人为直线
+- 它们并不总是跟真实地形走
+
+### Suggested layer order during debugging
+
+建议调试期临时把地球层次明确成：
+
+1. base earth texture
+2. coastline / borders overlay
+3. terrain relief
+4. cables / landing points / bgp / satellites
+
+这样会比现在更容易判断：
+
+- 山脉是否位于正确区域
+- terrain 是否和地表对齐
+- 国界/海岸是否漂移
+
+### Suggested data source for the calibration overlay
+
+优先用 `Natural Earth` 的轻量全球矢量数据：
+
+- 海岸线（coastline）
+- Admin 0 国界线（country borders）
+
+优点：
+
+- 全球一致
+- 轻量
+- 很适合当前 Three.js globe 做 overlay
+
+### Recommended execution path
+
+#### Phase A — Add reference overlays
+
+先加两层可开关的参考线：
+
+- 海岸线
+- 国界线
+
+这两层的目标不是最终美术表现，而是调试 / 校准。
+
+#### Phase B — Recalibrate terrain against coastline
+
+有了海岸线以后，再重新看 terrain：
+
+- terrain 是否和大陆边缘错位
+- 地球纹理、本初子午线、terrain 采样之间是否有固定偏移
+
+#### Phase C — Decide whether to keep the current terrain path
+
+这时再决定后面的路线：
+
+- 如果发现真实高程整体是对的，只是缺少 shading / readability  
+  继续保留当前 DEM + terrain overlay 路线
+- 如果发现整球采样投影、本初子午线或 overlay 关系本身就很别扭  
+  再考虑重做 terrain pipeline
+
+### Practical recommendation
+
+当前阶段不建议“从头开始重做 terrain”。
+
+更稳的策略是：
+
+- 暂停继续盲调 terrain 参数
+- 先补海岸线 / 国界线作为校准参照层
+- 再基于参照层判断 terrain 是“参数没调好”，还是“整条实现路径有偏移”
+
+## Recommended Geometry Model
+
+### First usable model
+
+保留一层独立 terrain sphere：
+
+- base earth sphere：贴纹理、昼夜、海洋
+- terrain sphere：略高于地球半径，真实高程位移
+
+建议：
+
+- `terrainBaseRadius = CONFIG.earthRadius + 0.2`
+- 高度缩放使用真实米制换算，再乘一个可调 exaggeration
+
+示例关系：
+
+- `heightWorld = (elevationMeters / 6371000) * CONFIG.earthRadius * exaggeration`
+
+建议第一阶段 `exaggeration = 1.3 ~ 1.8`
+
+因为完全真实比例在全球球体上会太平，看不出来。
+
+## Tile Decoding Plan
+
+### Terrarium decode
+
+对于每个高程 tile 像素：
+
+```text
+heightMeters = (R * 256 + G + B / 256) - 32768
+```
+
+### Sampling path
+
+对于 terrain mesh 上每个顶点：
+
+1. 将顶点方向转成经纬度
+2. 将经纬度映射到 Web Mercator tile 坐标
+3. 找到对应的 tile 和像素
+4. 解码高程
+5. 将顶点沿法线方向抬升
+
+### Needed helpers
+
+建议新增：
+
+- `latLonToTileXY(lat, lon, z)`
+- `tilePixelFromLatLon(lat, lon, z, tileSize)`
+- `decodeTerrariumHeight(r, g, b)`
+
+## Caching Strategy
+
+为了不让地形开关每次重开都重新抓全量 tile：
+
+- terrain tile 按 `z/x/y` 存到内存缓存
+- terrain mesh 结果也缓存一份
+- 当用户关闭/开启 terrain：
+  - 直接复用已有位移结果
+
+建议：
+
+- `Map<string, Float32Array | ImageBitmap>`
+
+## Material Strategy
+
+第一阶段不要复杂化。
+
+建议 terrain material：
+
+- 半透明低饱和地形色
+- 比 base earth 稍亮或稍偏冷
+- 保留当前 HUD 风格下的可读性
+
+第一阶段不需要：
+
+- 真实土地覆被纹理
+- 独立卫星影像贴 terrain
+
+因为那会和现有地球纹理、云层、昼夜 shader 打架。
+
+## Integration Points
+
+### Files to change
+
+- [earth.js](/home/ray/dev/linkong/planet/frontend/public/earth/js/earth.js)
+  - 重写 `createTerrain()`
+  - 删除 simplex noise 占位逻辑
+- [main.js](/home/ray/dev/linkong/planet/frontend/public/earth/js/main.js)
+  - 初始化 terrain 数据加载
+  - 控制 terrain readiness / loading message
+- [controls.js](/home/ray/dev/linkong/planet/frontend/public/earth/js/controls.js)
+  - `toggleTerrain` 逻辑保持，但应能区分：
+    - mesh 已就绪
+    - 正在加载
+- [constants.js](/home/ray/dev/linkong/planet/frontend/public/earth/js/constants.js)
+  - 新增 `TERRAIN_CONFIG`
+- 新文件：
+  - `frontend/public/earth/js/terrain.js`
+
+### Suggested new config
+
+建议新增：
+
+```js
+export const TERRAIN_CONFIG = {
+  enabled: true,
+  tileSize: 256,
+  baseZoom: 4,
+  baseRadiusOffset: 0.2,
+  exaggeration: 1.5,
+  opacity: 0.55,
+  color: 0x6c876f,
+  maxConcurrentRequests: 8,
+  cacheEnabled: true,
+};
+```
+
+## Loading UX
+
+地形第一次开启时，不能像现在一样瞬时切换。
+
+建议：
+
+- 如果地形数据尚未准备：
+  - 顶部状态条显示：`正在加载真实地形数据...`
+- 完成后：
+  - `真实地形已就绪`
+
+如果加载失败：
+
+- 保留 base earth
+- 显示轻量错误提示
+- 不要让 terrain 开关卡死在“开”状态
+
+## Risks
+
+### 1. Global tile count too high
+
+即使 `z=5` 全球 tile 数也不少。
+
+缓解：
+
+- 第一阶段限定低 zoom
+- 并发上限
+- 缓存
+
+### 2. Mesh resolution too low
+
+如果球面分段太低，山脉会被抹平。
+
+缓解：
+
+- 第一阶段先选一个中等分辨率
+- 用 exaggeration 保证可见性
+
+### 3. Existing overlays may z-fight with terrain
+
+海缆、登陆点、BGP、卫星相关对象都假设地球半径固定。
+
+缓解：
+
+- terrain sphere 单独作为 overlay
+- overlay 保持略低或略高的固定 offset
+- 必要时局部调整 landing point / cable altitude offset
+
+### 4. Mercator sampling distortion near poles
+
+Web Mercator 在高纬会有失真。
+
+缓解：
+
+- 第一阶段接受
+- 后续若需要更严格极区质量，再上 geodetic reprojection pipeline
+
+## Acceptance Criteria
+
+第一阶段完成后，应满足：
+
+1. `地形 terrain` 开关开启时，地表起伏明显不再是随机噪声
+2. 喜马拉雅、安第斯、落基山、东非高原等全球大尺度地形可辨认
+3. 关闭/重新开启 terrain 不重复全量请求
+4. 不破坏：
+   - 海缆
+   - 卫星
+   - BGP
+   - 地球昼夜
+   - 天球层
+
+## Suggested Execution Order
+
+1. 引入 `TERRAIN_CONFIG`
+2. 新建 `terrain.js`
+3. 实现 Terrarium tile 请求与 decode
+4. 用低 zoom 全球 tile 构建真实 terrain sphere
+5. 接管 `toggleTerrain()`
+6. 调整 terrain material 和高度 exaggeration
+7. 做缓存
+8. 再考虑第二阶段局部高分 refinement

+
+## Recommendation Summary
+
+如果现在就要开始做，我建议直接按这条路线开工：
+
+- 第一阶段接入 Terrarium 全球高程 tile
+- 替换掉当前 simplex 假地形
+- 先做一层真实可见的全球 terrain overlay
+- 等第一阶段稳定，再做视角高分 refinement
+
+这是对当前项目风险最低、最贴合现有 Earth 架构的一条路。

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

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

+
+## 目标
+
+这份计划用于统一 `aiprovider`、`backend AI facade`、`Playground` 页面，以及后续 `BGP / 告警 / 数据源健康` 等 AI 入口的演进方向。
+
+当前原则：
+
+- `aiprovider` 继续作为独立模型网关
+- `backend` 继续作为稳定业务入口
+- `frontend` 负责测试台和业务 UI
+- 先做“可控、可验证、可解释”的 AI 能力，再逐步引入 agent/tool calling
+
+## 当前已完成
+
+### 1. AI 网关基础层
+
+已完成：
+
+- 独立 `aiprovider` 服务
+- `backend -> aiprovider -> model provider` 调用链
+- `provider/status` 与 `situational-awareness/analyze` 稳定接口
+- `X-Request-ID` 透传
+- 轻量超时与重试
+- MiniMax / Anthropic-compatible / OpenAI-compatible / Ollama 适配

+
+### 2. 本地运行与配置打通
+
+已完成：
+
+- `planet.sh` 启动链路纳入 `aiprovider`
+- `planet.sh` 启动完成后输出 Playground 入口
+- `docker-compose.yml` 为 `aiprovider` 加入 `env_file`
+- `backend/.env` 与 `aiprovider/.env` 两侧 service token 对齐
+- `Playground` 状态缓存，避免页面切换时每次都重新请求 provider 状态

+
+已完成：
+
+- 新增前端路由 `/playground`
+- 左侧 `Provider 状态 + 测试说明`
+- 右侧 `请求 / 结果` Tabs
+- `Provider 状态` 支持手动刷新
+- `测试说明` 支持折叠
+- 内部区域采用细滚动条
+- 页面布局开始遵循“单屏工作区 + 模块内部滚动”规范

+
+## 当前限制
+
+### 1. Playground 还是 prompt playground，不是 agent playground
+
+当前 `Playground` 的 `观察项 / 目标 / 约束条件` 都是人工输入。
+
+模型现在拿到的是：
+
+- 你手工输入的结构化字段
+- 后端传递的少量静态上下文
+
+模型现在拿不到：
+
+- 实时 BGP 事件
+- 真实告警列表
+- 数据源健康状态
+- 自动检索结果
+- tool calling / skills / 自主取数
+
+### 2. `situational-awareness/analyze` 还是通用提示词接口
+
+当前更适合：
+
+- 测试链路
+- 测试模型输出风格
+- 验证不同 provider 是否正常返回
+
+当前还不适合：
+
+- 直接当真实态势系统主入口
+- 让用户手工维护长期分析模板
+- 代替专用业务研判接口
+
+### 3. 还没有可验证的真实业务输入注入
+
+目前最缺的是：
+
+- 从业务系统自动整理“事实输入”
+- 再把这些事实喂给 AI
+
+而不是继续让用户在 Playground 手工输入真实事件摘要。
+
+## 短期计划
+
+### Phase A: Playground 收敛为稳定测试台
+
+目标：
+
+- 保持 Playground 简洁可用
+- 不再继续堆“高级参数”
+
+工作项：
+
+- 继续微调左侧 `Provider 状态` 与 `测试说明` 的空间策略
+- 保持 `请求 / 结果` 为单一主工作区
+- 不引入盲填式高级字段
+- 统一滚动条、卡片、溢出行为
+
+完成标准：
+
+- 笔记本视口下依然可用
+- 各模块标题可见
+- 主要阅读区始终是右侧 Tabs
+
+### Phase B: BGP AI 简报
+
+目标：
+
+- 不再依赖手工填写“观察项”
+- 让系统自动把真实 BGP 数据注入 AI
+- 让 BGP 页面逐步从“摘要汇总”升级为“证据驱动的区域态势分析”
+
+建议实现：
+
+- 新增专用后端接口，例如：
+  - `POST /api/v1/ai/bgp/brief`
+- 后端自动读取：
+  - incidents summary
+  - anomalies
+  - recent events
+  - collector coverage summary
+- 后端将结构化事实注入 `context / observations`
+- 前端在 BGP 页面增加“生成 AI 简报”
+
+当前阶段说明：
+
+- 第一版 `BGP AI 简报` 允许先落地为“值班摘要生成器”
+- 也就是先把 incidents / anomalies / events / collector coverage 自动注入
+- 允许模型先做事实摘要、风险归纳、建议动作
+
+但这不应被视为 Phase B 的最终形态。
+
+Phase B 后续还需要补齐：
+
+- prefix geography 证据注入
+  - `iptoasn`
+  - `opengeofeed`
+  - `nro_delegated`
+- 基于 `affected_regions` 与 prefix geography 的区域聚合
+- 区分“真实区域热度”与“collector coverage 偏差”
+- 对高风险 prefix / ASN 给出更明确的国家、城市、运营商归属线索
+- 让 AI 输出明确回答：
+  - 哪些区域正在异常升温
+  - 哪些结论只是观测站偏差
+  - 当前还缺哪些区域证据
+
+完成标准：
+
+- 用户不需要手工录入 BGP 观察项
+- AI 输出能明确区分“事实”和“研判”
+- AI 不只是复述总量和最近几条事件，还能利用 prefix geography 与 affected regions 做区域态势判断
+- 输出中能明确指出：
+  - 高风险区域
+  - 区域证据来源
+  - collector coverage 偏差对判断的影响
+
+### Phase C: 告警 / 数据源健康 AI 简报
+
+目标：
+
+- 复用同样模式，扩展到其他模块
+
+建议入口：
+
+- `Alerts` 页面：异常与告警摘要
+- `DataSources` 页面：采集失败与健康状态总结
+
+原则：
+
+- 每个业务页优先做“专用 AI 简报”
+- 不优先做“万能大聊天框”
+
+## 中期计划
+
+### 1. Assessment Layer
+
+目标：
+
+- 不只返回自由文本
+- 返回结构化的 assessment
+
+建议输出字段：
+
+- summary
+- key_risks
+- evidence
+- recommendations
+- confidence
+- missing_data
+
+这样后续才能：
+
+- 持久化
+- 回看
+- 对比不同时间的 AI 结论
+- 在 Earth / Dashboard / BGP 页面稳定展示
+
+### 2. Evidence-first Runtime
+
+目标：
+
+- 所有 AI 分析先取真实数据，再调模型
+
+原则：
+
+- 先 evidence
+- 再 prompt
+- 最后才是自由生成
+
+优先要做的不是更强聊天，而是：
+
+- 更稳定的数据注入
+- 更一致的事实模板
+- 更清晰的结果结构
+
+### 3. 按页面提供专用入口
+
+目标：
+
+- 让 AI 成为业务视图的一部分，而不是孤立 playground
+
+优先顺序建议：
+
+1. `BGP` AI 简报
+2. `Alerts` AI 简报
+3. `DataSources` 健康研判
+4. `Dashboard` 总览总结
+
+## 长期计划
+
+### 1. Tool Calling / Agent Runtime
+
+只有在以下基础稳定后再推进：
+
+- 数据源健康信号稳定
+- BGP / Alerts / Datasource evidence 注入稳定
+- assessment 结构稳定
+
+长期可做能力：
+
+- AI 调用受控工具查询业务数据
+- AI 调用检索/web search 做外部验证
+- AI 生成建议而不是直接修改系统
+- 审核后触发受控动作
+
+### 2. 受控动作与闭环
+
+潜在方向：
+
+- 根据健康异常生成修复建议
+- 根据态势变化生成处理建议
+- 进入 review queue
+- 审批后执行
+- 验证结果并形成闭环
+
+### 3. 多模块统一 AI 体验
+
+长期目标不是一个孤立 Playground，而是：
+
+- 每个业务页都有自己的 AI 入口
+- 共享统一的 backend AI facade
+- 共享统一的 assessment 结构
+- 共享统一的 evidence 注入与审计链路
+
+## 设计决策总结
+
+### 为什么保留 `aiprovider`
+
+因为它已经很好地承担了：
+
+- provider 适配
+- 协议兼容
+- service token 边界
+- 独立重启与部署
+
+因此短期内不建议把它并回 `backend`。
+
+### 为什么 Playground 不做成万能聊天页
+
+因为当前更需要的是：
+
+- 稳定测试链路
+- 可验证业务输入
+- 专用分析入口
+
+而不是一个泛化但没有真实数据支撑的聊天框。
+
+### 为什么优先做专用 AI 简报
+
+因为：
+
+- 数据可以自动注入
+- 用户心智更清晰
+- 输出更容易结构化
+- 更容易校验事实与研判是否一致
+
+## 下一步建议
+
+按优先级建议接下来这样做：
+
+1. 稳住 `Playground` 当前布局，不再大幅重做
+2. 在 `BGP` 页面新增专用 “AI 简报” 入口
+3. 后端新增 `BGP brief` 专用接口，自动注入真实数据
+4. 补齐 `BGP brief` 的区域态势证据层
+5. 把 AI 输出逐步从自由文本升级为结构化 assessment
+
+### BGP Brief 后续子项
+
+为避免把“已有 AI 简报”误判成“区域分析已完成”，这里单独记录 `BGP brief` 的后续 backlog：
+
+1. 把高风险 prefix 命中的 `iptoasn / opengeofeed / nro_delegated` 结果注入 brief context
+2. 按国家/城市聚合 active incidents、anomalies、affected prefixes，生成区域热点事实层
+3. 把 collector coverage 与区域热点并排注入，避免模型把观测偏差误判成区域风险
+4. 对高风险 ASN / prefix 追加归属线索，如国家、城市、可能运营商或注册区域
+5. 在输出结构中单独增加：
+   - 区域态势
+   - 证据来源
+   - 观测偏差说明
+   - 缺失区域证据

+# Earth Frontend Context
+
+本文件描述当前 Earth 大屏前端的真实结构，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。
+
+相关规则建议一起参考：
+
+- [rules.md](/home/ray/dev/linkong/planet/rules.md)
+- [frontend-layout-guidelines.md](/home/ray/dev/linkong/planet/docs/technical/frontend-layout-guidelines.md)
+
+## 当前目标
+
+Earth 前端不是普通管理页，它是独立的大屏展示前端。当前产品目标是：
+
+- 维持地球视图的空间感和可读性
+- 让 HUD、图层、媒体面板、BGP、卫星、海缆等保持统一交互
+- 把加载中、已启用、已隐藏、锁定中这类状态做清楚
+
+## 当前入口
+
+React 路由入口：
+
+- [Earth.tsx](/home/ray/dev/linkong/planet/frontend/src/pages/Earth/Earth.tsx)
+
+当前做法很简单：
+
+- React 页面只负责提供一个全屏 `iframe`
+- 真正的 Earth 应用运行在：
+  - [index.html](/home/ray/dev/linkong/planet/frontend/public/earth/index.html)
+
+所以 Earth 前端本质上是 `public/earth` 下的一套独立静态应用。
+
+## 当前文件分层
+
+### 1. 页面入口与结构
+
+- [index.html](/home/ray/dev/linkong/planet/frontend/public/earth/index.html)
+
+职责：
+
+- HUD 基础 DOM
+- 图层面板
+- 媒体面板
+- 工具栏
+- 设置弹窗
+- 兼容旧元素 id
+
+### 2. 主运行时
+
+- [main.js](/home/ray/dev/linkong/planet/frontend/public/earth/js/main.js)
+
+职责：
+
+- 地球初始化
+- Three.js 场景组装
+- 数据加载与刷新
+- 各图层集成
+- Earth 级别状态同步
+
+### 3. 地球控制层
+
+- [controls.js](/home/ray/dev/linkong/planet/frontend/public/earth/js/controls.js)
+
+职责：
+
+- 工具栏交互
+- 图层面板交互
+- 旋转/缩放/布局
+- HUD 面板拖拽
+- 图层开关状态机
+- Earth 设置读取、持久化与重置
+
+这份文件是 Earth 前端当前最核心的 UI 控制入口。
+
+### 4. UI 与状态消息
+
+- [ui.js](/home/ray/dev/linkong/planet/frontend/public/earth/js/ui.js)
+
+职责：
+
+- loading 面板
+- status message
+- tooltip / error / 清理逻辑
+
+### 5. 地球与地形
+
+- [earth.js](/home/ray/dev/linkong/planet/frontend/public/earth/js/earth.js)
+- [terrain.js](/home/ray/dev/linkong/planet/frontend/public/earth/js/terrain.js)
+
+职责：
+
+- 地球球体、云层、大气
+- 真实地形 mesh
+- terrain tile 拉取、解码、位移、着色
+
+### 6. 图层模块
+
+- [satellites.js](/home/ray/dev/linkong/planet/frontend/public/earth/js/satellites.js)
+- [cables.js](/home/ray/dev/linkong/planet/frontend/public/earth/js/cables.js)
+- [bgp.js](/home/ray/dev/linkong/planet/frontend/public/earth/js/bgp.js)
+- [bgp-cruise-adapter.js](/home/ray/dev/linkong/planet/frontend/public/earth/js/bgp-cruise-adapter.js)
+- [news.js](/home/ray/dev/linkong/planet/frontend/public/earth/js/news.js)
+- [tv.js](/home/ray/dev/linkong/planet/frontend/public/earth/js/tv.js)
+- [layer-startup-tasks.js](/home/ray/dev/linkong/planet/frontend/public/earth/js/layer-startup-tasks.js)
+- [cruise-sequencer.js](/home/ray/dev/linkong/planet/frontend/public/earth/js/cruise-sequencer.js)
+- [callout-connector.js](/home/ray/dev/linkong/planet/frontend/public/earth/js/callout-connector.js)
+
+职责：
+
+- 各自的数据层
+- 开关行为
+- 面板内容
+- hover/lock/selection 语义
+
+其中 Earth 启动加载链现在也拆成了两层：
+
+- `controls.js`
+  - 提供图层注册表与启动元信息
+- `layer-startup-tasks.js`
+  - 提供图层启动任务注册表
+  - 通过 `registerLayerStartupTask(id, taskFactory)` 扩展启动任务
+- `main.js`
+  - 只负责读取排序后的启动图层，再按映射执行队列
+
+其中巡航模式现在已经拆成两层：
+
+- `cruise-sequencer.js`
+  - 负责目标队列顺序、停留时长、切换节奏、打断与恢复
+- `callout-connector.js`
+  - 负责卡片连线 SVG、路径计算与绘制动画
+- `bgp-cruise-adapter.js`
+  - 负责 BGP 巡航展示适配：目标排序、卡片落点、连线路径、focus/overlay/info-card 时序
+
+当前 BGP 巡航只是这套能力的一个调用方，不应再把“按队列巡航”和“BGP 事件展示”混写在同一个状态机里。
+
+## 当前样式分层
+
+Earth 的 CSS 不是一份大样式表，而是分层管理：
+
+- [base.css](/home/ray/dev/linkong/planet/frontend/public/earth/css/base.css)
+- [hud.css](/home/ray/dev/linkong/planet/frontend/public/earth/css/hud.css)
+- [toolbar.css](/home/ray/dev/linkong/planet/frontend/public/earth/css/toolbar.css)
+- [layer-panel.css](/home/ray/dev/linkong/planet/frontend/public/earth/css/layer-panel.css)
+- [info-panel.css](/home/ray/dev/linkong/planet/frontend/public/earth/css/info-panel.css)
+- [legend.css](/home/ray/dev/linkong/planet/frontend/public/earth/css/legend.css)
+- [earth-stats.css](/home/ray/dev/linkong/planet/frontend/public/earth/css/earth-stats.css)
+- [coordinates-display.css](/home/ray/dev/linkong/planet/frontend/public/earth/css/coordinates-display.css)
+- [tv-panel.css](/home/ray/dev/linkong/planet/frontend/public/earth/css/tv-panel.css)
+
+当前建议：
+
+- 通用 HUD 壳层写进 `hud.css`
+- 单一面板特性写进各自子文件
+- 不要把业务状态样式再散回 `index.html`
+
+## 当前图层开关状态语义
+
+Earth 图层按钮现在不应再只有“开/关”两态，而应支持：
+
+- `inactive`
+- `active`
+- `loading`
+
+当前入口在：
+
+- [controls.js](/home/ray/dev/linkong/planet/frontend/public/earth/js/controls.js)
+- [layer-button-state.js](/home/ray/dev/linkong/planet/frontend/public/earth/js/layer-button-state.js)
+
+关键函数：
+
+- `updateLayerButtonState(button, isActive)`
+- `setLayerButtonState(button, options)`
+
+`setLayerButtonState` 负责：
+
+- `loading` 样式
+- `aria-busy`
+- 按钮禁用
+- tooltip 更新
+- 绑定状态文本更新
+- 可选同步 `active`
+
+因此后续如果别的图层也需要异步启用，应该直接走这套状态机，而不是再手写一套临时 loading class。
+
+另外，Earth 图层控制现在已经收成“注册表驱动”：
+
+- 图层元数据
+  - `id`
+  - `icon`
+  - `label`
+  - `meta`
+  - `buttonId`
+  - `persist`
+  - `startupPriority`
+  - `startupMode`
+  - `startupLabel`
+  - `startupMessage`
+- 图层行为
+  - `getVisible()`
+  - `setVisible(next, options)`
+
+当前入口仍在 [controls.js](/home/ray/dev/linkong/planet/frontend/public/earth/js/controls.js)。
+
+这意味着后续新增图层时，优先应补一条图层注册定义，而不是同时去改：
+
+- 图层面板 HTML
+- 持久化快照
+- 初始化恢复
+- click 绑定
+
+这四处现在都应该由注册表派生。
+
+其中：
+
+- `startupPriority`
+  - 描述图层参与启动加载时的顺序
+- `startupMode`
+  - `visible`
+    - 仅当前图层处于启用/可见状态时，才加入启动加载队列
+  - `preload`
+    - 即使当前图层未显示，也会参与启动预加载
+
+当前 `main.js` 会通过注册表读取排序后的启动图层列表，再动态拼装启动加载队列，而不是手写一串固定步骤。像 BGP 这类需要尽早准备数据、但不一定默认显示的图层，应该优先走 `startupMode: "preload"`，而不是在启动流程里写隐式特判。
+
+此外，启动阶段给用户看的提示文案也应尽量从注册表派生：
+
+- `startupLabel`
+  - 用于描述当前启动任务的业务名称
+- `startupMessage`
+  - 用于描述启动中的提示文案
+  - 可以是字符串
+  - 也可以是对象，用于像海缆这种“准备阶段 / 主加载阶段”两段式文案
+
+这样后续新增会参与启动加载的图层时，顺序、模式和提示文案都在同一处定义，不需要再去 `main.js` 里补第二套常量。
+
+### `data-status-target`
+
+图层按钮可以通过：
+
+- `data-status-target`
+
+指向一个状态文本节点。当前 terrain 已接入：
+
+- 按钮：`#toggle-terrain`
+- 状态节点：`#terrain-status`
+
+以后别的异步图层也可以沿用这套约定。
+
+## 当前设置持久化
+
+Earth 设置面板当前由 [controls.js](/home/ray/dev/linkong/planet/frontend/public/earth/js/controls.js) 统一负责：
+
+- 捕获默认值
+- 从 `localStorage` 读取上次设置
+- 初始化应用当前设置
+- 用户变更后即时持久化
+- 一键重置回默认值
+
+当前持久化的范围是：
+
+- 旋转模式
+- 地球默认大小（作为重置视角、缩放重置和巡航视图的默认 zoom 真源）
+- HUD 面板显示/隐藏
+- 图层控制开关：`地形 / 卫星 / 轨迹 / 海缆 / BGP`
+- 地形透明度
+
+也就是说，Earth 设置不是一次性 UI 状态了，而是本地设备级偏好。后续如果再加入新的设置项，应优先接入同一条持久化链，而不是各自散着写 `localStorage`。
+
+## 当前地形链路
+
+真实地形首次启用会慢，原因不只是一个：
+
+1. 需要拉取 Terrarium 瓦片
+2. 需要解码图片
+3. 需要按顶点采样高程
+4. 需要重新写入 geometry 和 color
+5. 需要重新计算法线与包围体
+
+当前入口在：
+
+- [terrain.js](/home/ray/dev/linkong/planet/frontend/public/earth/js/terrain.js)
+
+当前已经做了两层体验优化：
+
+1. 图层开关 loading 状态持续可见
+2. 页面空闲时会预热 `ensureTerrainReady()`
+
+也就是说，后续再继续优化 terrain 时，优先顺序应该是：
+
+1. 先保证用户感知正确
+2. 再压缩首次等待
+3. 最后才做更激进的几何/瓦片优化
+
+## 当前高频风险点
+
+### 1. 视觉状态和业务状态不同步
+
+Earth 里最常见的 bug 不是“没渲染”，而是：
+
+- 图层关了，tooltip 还在
+- 锁定对象隐藏了，info card 还在
+- legend 没跟图层切换
+- loading 已结束，但按钮还像没开
+
+后续改动必须优先检查状态同步。
+
+### 2. HUD 布局问题先查结构，不要先打 CSS 补丁
+
+Earth HUD 历史上反复出现：
+
+- 面板只剩一条缝
+- markdown 被裁掉
+- tabs/iframe 被 `overflow: hidden` 吃掉
+
+优先检查：
+
+1. 谁负责高度
+2. 谁负责滚动
+3. 哪一层在裁剪
+
+不要上来先加 `overflow: hidden` 或额外包装层。
+
+### 3. Transitional path 必须收口
+
+Earth 已经经历过多轮 HUD、toolbar、media panel 重构，所以最容易积累：
+
+- 旧 helper
+- 旧 class
+- 旧 fallback 逻辑
+- 已废弃变体
+
+每次大功能完成后，都要做一次 cleanup pass。
+
+### 4. 巡航与业务事件不要再深度耦合
+
+当前正确边界应该是：
+
+- 通用巡航层只知道：
+  - 当前目标
+  - 队列顺序
+  - 相机 focus
+  - 停留 / 隐藏 / 切换
+- 业务模块只负责：
+  - 提供目标队列
+  - 提供 focus 坐标
+  - 提供卡片内容
+  - 提供高亮/图层副作用
+
+如果以后再给海缆、卫星或新闻做巡航，不应复制一套新的 `main.js` 状态变量，而应复用：
+
+- [cruise-sequencer.js](/home/ray/dev/linkong/planet/frontend/public/earth/js/cruise-sequencer.js)
+- [callout-connector.js](/home/ray/dev/linkong/planet/frontend/public/earth/js/callout-connector.js)
+- [bgp-cruise-adapter.js](/home/ray/dev/linkong/planet/frontend/public/earth/js/bgp-cruise-adapter.js) 这种业务适配层模式
+
+## 当前推荐改动方式
+
+如果后续继续改 Earth，建议按这个顺序：
+
+1. 先确认改的是：
+   - Three.js 渲染层
+   - HUD 结构层
+   - 图层状态层
+   - 面板内容层
+2. 如果涉及图层按钮，优先接入统一状态机
+3. 如果涉及可见性切换，检查 tooltip / legend / info-card / lock 是否一起收口
+4. 如果涉及面板布局，先查结构再动 CSS
+
+## 当前与控制台前端的边界
+
+Earth 前端和控制台前端不是同一套 UI 系统：
+
+- 控制台前端：React + Ant Design 工作台
+- Earth 前端：`public/earth` 原生 HUD + Three.js 展示面
+
+因此：
+
+- Earth 不应该直接复用 Ant Table / AppLayout 语义
+- 控制台也不应该照搬 Earth HUD 动画和玻璃层语言

+控制台相关结构见：
