+
+# /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"

+allowed-tools: ["Read", "Edit", "Bash", "Grep", "Glob"]
+---
+
+# /goal-driven — 目标驱动执行模式
+
+使用 `lidangzzz/goal-driven` 的核心思想来推进复杂任务：先固定目标与成功标准，再持续执行和反复验收，直到标准真正满足。
+
+适用场景：
+
+- 长周期实现任务
+- 高复杂度工程任务
+- 可被明确验收的研究、实现、迁移、验证类工作
+
+不适用场景：
+
+- 纯脑暴
+- 无法定义成功标准的模糊任务
+- 很小的一次性修改
+
+## 输入要求
+
+若 `$ARGUMENTS` 只包含目标，没有成功标准，先补全一版可执行的成功标准再开始。
+
+启动时先输出：
+
+```md
+Goal
+- ...
+
+Criteria for success
+- ...
+
+Plan
+1. ...
+2. ...
+3. ...
+
+Verification
+- ...
+```
+
+## 执行规则
+
+1. 先把任务固化为两个核心块：
+   - `Goal`
+   - `Criteria for success`
+
+2. 成功标准必须尽量客观，可验证，可落地。
+   优先写成：
+   - 需要交付什么
+   - 需要通过哪些测试或验证
+   - 如何判断结果真的完成
+
+3. 进入持续执行循环：
+   - 完成一个阶段
+   - 检查当前结果是否满足成功标准
+   - 若未满足，明确剩余差距并继续推进
+
+4. 任何“完成了”“差不多了”“已实现”之类的结论，都必须经过验证，不能直接接受。
+
+5. 如果验证失败：
+   - 明确指出哪条成功标准没满足
+   - 继续工作，不要把阶段性进展误判为完成
+
+6. 只有在以下情况之一才能停止：
+   - 成功标准已满足
+   - 用户明确要求停止
+
+## 执行风格
+
+- 重证据，轻口头判断
+- 重验收，轻自我感觉
+- 优先用测试、日志、产物、对比结果来证明完成
+- 对长期任务保持“未达标就继续”的节奏
+
+## 简版模板
+
+```md
+Goal: [[[[[在此填写最终目标]]]]]
+
+Criteria for success: [[[[[在此填写成功标准]]]]]
+
+循环执行：
+1. 推进任务
+2. 检查是否满足成功标准
+3. 若未满足，继续工作
+4. 直到满足标准或用户明确停止

+
+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

+description: Use when the user asks to clean up, lint, or review uncommitted code for common code smells — duplicate logic, magic numbers, unclear naming, dead code, style inconsistencies. Fixes issues without changing any runtime behavior.
+---
+
+# 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

+description: Run a goal-driven execution loop for very large, long-horizon, rigorously verifiable tasks. Use when the user explicitly wants the lidangzzz/goal-driven method, a master-agent plus worker-agent style workflow, or a persistent loop that keeps working until concrete success criteria are satisfied.
+---
+
+# Goal-Driven
+
+Use this skill when the user wants a strict goal-driven workflow for a hard task with:
+
+- one clear end goal
+- explicit success criteria
+- repeated verification against those criteria
+- continued execution until the criteria are actually met
+
+This skill is adapted from `lidangzzz/goal-driven`, but trimmed for local skill use to avoid bloating context.
+
+## When To Use
+
+Use it for tasks like:
+
+- compilers, interpreters, theorem-like proof work, deep refactors
+- long-running system design or implementation work
+- problems that are expensive and complex, but still objectively testable
+
+Do not use it for:
+
+- vague brainstorming without a success condition
+- short one-shot edits
+- tasks where "done" cannot be evaluated in a meaningful way
+
+## Core Model
+
+The workflow has two roles:
+
+1. Master role
+   Defines the goal, defines the success criteria, audits progress, and decides whether the work is actually complete.
+
+2. Worker role
+   Keeps advancing the task toward the goal. If a result is partial, stalled, or unverifiable, the worker continues.
+
+In Codex, only use actual subagents when the user explicitly asks for delegation or subagent work and the platform supports it. Otherwise emulate the same loop locally: keep working, checkpointing, and re-verifying until the criteria are satisfied.
+
+## Workflow
+
+1. Normalize the task into two blocks:
+   - `Goal`
+   - `Criteria for success`
+
+2. Make the criteria concrete and testable.
+   Good criteria usually include:
+   - required outputs
+   - required validations or tests
+   - edge cases or coverage thresholds
+   - what evidence proves completion
+
+3. Break the work into milestones that can each produce evidence.
+
+4. Execute the next milestone.
+   If subagents are explicitly allowed, the master may delegate bounded worker tasks.
+   If not, do the work locally but keep the master/worker mindset.
+
+5. Whenever work pauses, stalls, or appears complete, audit against the criteria directly.
+   Check artifacts, tests, logs, diffs, metrics, or other real evidence.
+
+6. If the criteria are not met, continue with a specific delta:
+   - what is still missing
+   - what evidence failed
+   - what the next worker pass must improve
+
+7. Stop only when the criteria are met, or when the user explicitly stops the process.
+
+## Operating Rules
+
+- Prefer objective checks over self-reported completion.
+- Do not confuse progress with completion.
+- If the worker says "done", verify it.
+- If verification fails, continue from the gap instead of restarting blindly.
+- Keep the goal stable unless the user changes it.
+- Tighten fuzzy criteria before sinking large amounts of effort.
+
+## Recommended Response Shape
+
+When starting a goal-driven task, structure the kickoff like this:
+
+```md
+Goal
+- ...
+
+Criteria for success
+- ...
+
+Current plan
+1. ...
+2. ...
+3. ...
+
+Verification
+- What evidence will prove completion

+5. Stop only when the criteria are satisfied or the user explicitly stops the process.
+
+Worker requirements:
+1. Break the task into subproblems.
+2. Keep producing concrete progress toward the goal.
+3. Report evidence, not just claims.
+4. Continue until the criteria are satisfied.

+2. If the worker stalls or claims completion, verify against the criteria.
+3. If verification fails, resume work from the remaining gap.
+4. Repeat until the criteria are met.

+
+## Notes
+
+- Stronger criteria produce better results than stronger rhetoric.
+- Prefer measurable checks such as tests, parity checks, generated artifacts, benchmarks, or reviewable outputs.
+- If the environment does not support subagents, emulate the same loop locally.

-description: Use when the user asks to release, bump version, update changelog/version files, or commit/push a repository release for the Planet repo. Applies the repo's versioning rules, updates all required version-bearing files, updates changelog/version-history, runs minimal relevant validation, and then commits/pushes when requested.

-
-# 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. If they ask to release a bugfix bundle, use a patch bump.
-
-## Required Files
-
-Every release bump must update these files together:
-
-- `/home/ray/dev/linkong/planet/VERSION`
-- `/home/ray/dev/linkong/planet/frontend/package.json`
-- `/home/ray/dev/linkong/planet/pyproject.toml`
-- `/home/ray/dev/linkong/planet/uv.lock`
-- `/home/ray/dev/linkong/planet/docs/CHANGELOG.md`
-- `/home/ray/dev/linkong/planet/docs/version-history.md`
-
-## Workflow
-
-1. Inspect the current worktree and current version.
-2. Decide the release type from the user request:
-   - feature
-   - bugfix
-   - release without code changes
-3. Compute the next version.
-4. Update all required version-bearing files.
-5. Add a concise but specific changelog entry:
-   - highlights
-   - important added/improved/fixed items
-   - mention the highest-signal files only
-6. Update `docs/version-history.md`:
-   - current dev version
-   - new timeline row with summary
-7. Run the smallest relevant validation available.
-8. Before commit, verify the target version is present in all required files.
-9. If the user asked for commit/push:
-   - stage the release files and code changes
-   - commit with a conventional message
-   - push to the requested branch, usually `dev`
-
-## Validation Guidance
-
-- Prefer scope-matched validation over broad expensive checks
-- Typical examples:
-  - Python backend edits: `python3 -m py_compile ...`
-  - Frontend edits: use the project-standard frontend build/check if available
-- If the environment prevents a check, say that explicitly in the final summary
-
-## Release Checklist
-
-Before closing the task, confirm:
-
-- version bump applied consistently
-- changelog updated
-- version history updated
-- generated/runtime artifacts are not accidentally staged
-- validation status recorded
-- commit and push completed if requested

+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

 启动服务后访问: `http://localhost:8000/docs`
 
+## WSL / Windows 局域网访问
+
+如果服务运行在 WSL 中，而你希望：
+
+- Windows 本机浏览器访问开发服务
+- 同一局域网内的手机或其他电脑访问开发服务
+
+推荐按下面顺序排查和配置。
+
+### 1. 在 WSL 中启动服务
+
+```bash
+./planet.sh start --allow-lan
+```
+
+这会让前端监听 `0.0.0.0:3000`，后端监听 `0.0.0.0:8000`。
+
+### 2. 先确认 WSL 内部服务正常
+
+在 WSL 中执行：
+
+```bash
+curl http://localhost:3000
+curl http://localhost:8000/health
+ss -ltnp | grep -E ':3000|:8000'
+```
+
+预期：
+
+- `3000` 返回前端 HTML
+- `8000/health` 返回健康检查 JSON
+- `ss` 中能看到 `0.0.0.0:3000` 和 `0.0.0.0:8000`
+
+如果这一步不通，先不要继续做 Windows 转发。
+
+### 3. 在 Windows 本机验证 localhost 直通
+
+在 Windows PowerShell 中执行：
+
+```powershell
+curl http://localhost:3000
+curl http://localhost:8000/health
+```
+
+在常见的 WSL2 开发环境下，Windows 通常可以直接通过 `localhost` 访问 WSL 中的服务。
+
+### 4. 如果需要让局域网设备访问，再做 Windows 端口转发
+
+注意：下面的命令必须在“以管理员身份运行”的 PowerShell 中执行。
+
+先把 Windows 对外网卡上的 `3000` / `8000` 转发到 Windows 本机 `127.0.0.1`：
+
+```powershell
+netsh interface portproxy delete v4tov4 listenaddress=0.0.0.0 listenport=3000
+netsh interface portproxy delete v4tov4 listenaddress=0.0.0.0 listenport=8000
+
+netsh interface portproxy add v4tov4 listenaddress=0.0.0.0 listenport=3000 connectaddress=127.0.0.1 connectport=3000
+netsh interface portproxy add v4tov4 listenaddress=0.0.0.0 listenport=8000 connectaddress=127.0.0.1 connectport=8000
+```
+
+再放行 Windows 防火墙：
+
+```powershell
+New-NetFirewallRule -DisplayName "WSL Planet 3000" -Direction Inbound -Action Allow -Protocol TCP -LocalPort 3000
+New-NetFirewallRule -DisplayName "WSL Planet 8000" -Direction Inbound -Action Allow -Protocol TCP -LocalPort 8000
+```
+
+检查转发规则是否生效：
+
+```powershell
+netsh interface portproxy show all
+```
+
+预期能看到：
+
+- `0.0.0.0:3000 -> 127.0.0.1:3000`
+- `0.0.0.0:8000 -> 127.0.0.1:8000`
+
+### 5. 查 Windows 局域网 IP，并让其他设备访问
+
+在 Windows PowerShell 中执行：
+
+```powershell
+ipconfig
+```
+
+找到当前联网网卡的 IPv4 地址，例如 `192.168.8.228`。
+
+局域网其他设备可访问：
+
+- `http://<Windows局域网IP>:3000/earth`
+- `http://<Windows局域网IP>:3000/admin`
+
+例如：
+
+- `http://192.168.8.228:3000/earth`
+
+### 6. 常见现象与判断
+
+- WSL 中 `curl localhost:3000` 能通，但 Windows 访问 `WSL 的局域网 IP:3000` 不通：这是正常现象之一，优先验证 Windows 的 `localhost:3000`
+- Windows `localhost:3000` 能通，但局域网设备访问 `Windows 局域网 IP:3000` 不通：通常缺少 `portproxy` 或防火墙放行
+- `whoami /groups` 中 `S-1-5-32-544` 显示 `deny only`：说明当前 PowerShell 不是提权管理员窗口
+
+### 7. 本项目一次性验证顺序
+
+建议固定按这个顺序验证：
+
+1. WSL 中执行 `curl http://localhost:3000`
+2. WSL 中执行 `curl http://localhost:8000/health`
+3. Windows 中执行 `curl http://localhost:3000`
+4. Windows 中执行 `curl http://localhost:8000/health`
+5. 管理员 PowerShell 配置 `portproxy` 和防火墙
+6. 用手机或其他电脑访问 `http://<Windows局域网IP>:3000/earth`
+

+- `.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.

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

+# Earth Compute Center BGP-Style Plan
+
+## Goal
+
+这份文档定义如何按照 BGP 模块的产品方式，把“算力中心”提升为 Earth 上的一级能力。
+
+这里的“按 BGP 方式”指的是：
+
+- 有独立的数据语义和接口入口
+- 有独立的 Earth 图层与图例
+- 有独立的 hover / click / 选中态 / 详情卡
+- 有独立的统计口径与后续专题页扩展空间
+
+这里的“按 BGP 方式”不指：
+
+- 机械复制 BGP 的 anomaly / incident / collector 三层事件模型
+- 为静态算力设施强行引入不必要的复杂告警语义
+
+算力中心本质上更接近“长期基础设施分布层”，不是“高频动态异常层”。
+因此应该复用 BGP 的模块化方法，而不是照搬 BGP 的事件结构。
+
+## Why
+
+当前仓库里已经有算力相关基础：
+
+- 后端已有 `top500` 和 `epoch_ai_gpu` 数据采集
+- 可视化接口已有 `/api/v1/visualization/geo/supercomputers` 和 `/api/v1/visualization/geo/gpu-clusters`
+- Earth 信息卡已对 `supercomputer` 和 `gpu_cluster` 做了基础类型兼容
+
+但当前能力还停留在“数据可取到”的阶段，没有形成像 BGP 那样完整的可视化模块：
+
+- Earth 缺少独立的算力图层加载模块
+- 缺少算力 marker 体系和视觉层级
+- 缺少算力图例、统计、开关和搜索接入
+- 缺少与海缆、BGP、卫星的关系表达
+- 缺少算力专题页和后续告警/研判扩展入口
+
+所以当前真正的缺口不是“有没有数据”，而是“有没有产品级模块”。
+
+## Core Principle
+
+算力中心应当采用和 BGP 一致的模块化分层：
+
+1. 数据层：稳定的数据契约和 GeoJSON 输出
+2. 渲染层：独立的 Earth 图层、marker 和视觉状态管理
+3. 交互层：hover、click、锁定态、详情卡、图例和统计
+4. 扩展层：后续专题页、关系分析、告警和 AI 研判
+
+但语义上必须保持算力中心自身的特点：
+
+- `site / center` 是主对象，不是事件
+- `capacity / rank / vendor / operator / status` 是主信息，不是异常严重度
+- `distribution / concentration / dependency` 是后续分析方向，不是第一阶段必须项
+
+## Recommended Scope
+
+第一版“算力中心”建议统一承载两类对象：
+
+- `supercomputer`
+- `gpu_cluster`
+
+并在 Earth 上收口为一个主题层：`compute_centers`
+
+这样做有几个好处：
+
+- 用户看到的是统一的“算力基础设施”语义，而不是零散数据源
+- 后端仍可保留 `top500` 和 `epoch_ai_gpu` 的来源差异
+- 前端可以在一个图层里再细分两种 marker 语言
+
+## Current Gap
+
+和 BGP 对比，当前差距主要在下面几层。
+
+### 1. Data Contract Gap
+
+现在的算力 GeoJSON 还是通用 `collected_data` 输出思路，字段较轻：
+
+- `gpu_cluster` 只有基础名称和地点
+- `supercomputer` 只暴露一部分性能字段
+- 缺少统一的 `site_type / operator / capacity_band / source / updated_at / confidence`
+- 缺少统一的算力层聚合出口
+
+### 2. Earth Rendering Gap
+
+当前 Earth 里没有类似 `bgp.js` 的算力模块：
+
+- `constants.js` 没有算力 API 路径和视觉配置
+- `main.js` 没有算力加载、拾取、状态同步和 HUD 更新
+- `controls.js` 没有算力图层开关和启动加载优先级
+- `layer-startup-tasks.js` 没有算力启动任务
+- `legend.js` / `ui.js` 没有算力统计与图例模式
+
+### 3. Interaction Gap
+
+虽然 `info-card.js` 支持基础字段，但还没有形成 BGP 那种完整交互链路：
+
+- 没有 hover / selected / dimmed 的视觉状态
+- 没有算力对象专属 tooltip 与摘要文案
+- 没有锁定后与其他基础设施的联动高亮
+- 没有搜索、统计卡和详情组织方式
+
+### 4. Product Expansion Gap
+
+当前还没有“算力中心”专题页与分析语义：
+
+- 没有全球分布/国家聚合/厂商聚合视图
+- 没有算力与海缆/BGP/区域的关系表达
+- 没有 AI brief / assessment 的后续落点
+
+## Architecture Direction
+
+推荐把算力中心做成“BGP 同级能力”，但采用更适合静态基础设施的结构。
+
+### Backend
+
+建议新增统一聚合接口，例如：
+
+- `/api/v1/visualization/geo/compute-centers`
+
+它的职责是把：
+
+- `top500`
+- `epoch_ai_gpu`
+
+统一转换成一个主题层输出，同时保留对象细分类型：
+
+- `site_type: supercomputer | gpu_cluster`
+
+建议统一字段至少包括：
+
+- `id`
+- `name`
+- `site_type`
+- `country`
+- `city`
+- `latitude`
+- `longitude`
+- `operator`
+- `vendor`
+- `capacity_value`
+- `capacity_unit`
+- `capacity_band`
+- `rank`
+- `source`
+- `updated_at`
+- `location_precision`
+- `geography_mode`
+- `is_estimated`
+- `estimated_reason`
+- `metadata`
+
+这里建议优先做“统一聚合出口”，而不是一开始就新增独立数据库表。
+
+原因：
+
+- 当前源数据更新频率低，先复用 `collected_data` 成本更低
+- 可以先把 Earth 产品体验做完整
+- 如果后续要做历史趋势、关系推断、告警，再评估是否拆成独立模型
+
+### Frontend Earth
+
+建议新增独立模块，例如：
+
+- `frontend/public/earth/js/compute-centers.js`
+
+职责参照 `bgp.js`：
+
+- 拉取算力中心 GeoJSON
+- 创建 marker
+- 管理 hover / selected / dimmed 状态
+- 输出图例项
+- 输出统计摘要
+- 提供 overlay 和详情格式化辅助函数
+
+推荐视觉分层：
+
+1. `supercomputer` 用更稳定、更规整的设施型符号
+2. `gpu_cluster` 用更活跃、更现代的密度型符号
+3. 选中态通过 halo / ring / related infrastructure highlight 表达
+
+视觉上应避免把算力中心做成“BGP 事件点”那种高频脉冲风格。
+它应该更像长期存在的高价值设施。
+
+## Phases
+
+## Phase 1: Unified Earth Layer
+
+目标：
+
+- 先把算力中心做成 Earth 上可用、可点、可解释的一级图层
+
+工作项：
+
+- 新增统一算力 GeoJSON 接口
+- 新增 `compute-centers.js`
+- 在 `constants.js` 增加 API 路径和视觉配置
+- 在 `controls.js` 增加算力图层开关与启动元数据
+- 在 `layer-startup-tasks.js` 增加算力启动加载任务
+- 在 `main.js` 接入算力拾取、hover、click、锁定态和 HUD 统计
+- 在 `ui.js` / `legend.js` / `index.html` 增加算力统计与图例入口
+- 在 `info-card.js` 提升算力详情字段组织
+- 对无法精确定位、但可按国家或弱线索推测的大概位置，仍然生成地图点位
+- 这类对象必须带显式“估算位置”状态，例如图标问号角标与详情说明
+
+完成标准：
+
+- Earth 上能独立显示/隐藏算力中心
+- 两类对象有可区分的视觉表达
+- hover / click / 详情卡 / 图例 / 统计全部打通
+- 精确位置与估算位置在图标或文案上可区分，不会误导为同一精度
+- 不干扰现有海缆、卫星、BGP 的交互链路
+
+## Phase 2: Relationship Layer
+
+目标：
+
+- 让算力中心不只是“点”，而是和其他基础设施产生上下文关系
+
+工作项：
+
+- 建立算力中心与国家/区域聚合摘要
+- 增加与附近海缆登陆点的关系提示
+- 增加与 BGP 事件/观测范围的空间邻近提示
+- 增加与卫星覆盖或区域连通性的实验性提示
+
+完成标准：
+
+- 点击算力中心时，用户能看到“它和哪些基础设施相关”
+- 信息表达以辅助判断为主，不做夸张推断
+
+## Phase 3: Compute Center Observatory
+
+目标：
+
+- 把算力中心从 Earth 图层扩展成独立专题观测能力
+
+工作项：
+
+- 新增算力中心专题页
+- 提供国家/厂商/类型/容量分布统计
+- 支持列表、筛选、详情和历史快照
+- 预留 AI brief / assessment 入口
+
+完成标准：
+
+- 算力中心不再只是 Earth 上的视觉点位
+- 能作为独立业务上下文进入日常观察与研判
+
+## Phase 4: Alerts And Assessment
+
+目标：
+
+- 在不滥造“假动态告警”的前提下，引入真正有价值的变化感知
+
+候选方向：
+
+- 新增大规模算力中心
+- 既有中心容量显著变化
+- 国家/区域集中度显著变化
+- 高价值中心与关键网络基础设施关系变化
+
+完成标准：
+
+- 告警来自可解释的结构变化
+- 不把静态数据硬做成噪声式实时事件流
+
+## Implementation Notes
+
+建议按下面顺序推进：
+
+1. 先统一 GeoJSON 契约
+2. 再做 Earth 独立模块和图层开关
+3. 再补详情卡、图例和统计
+4. 最后才做关系层和专题页
+
+这样可以避免一开始把范围摊得过大。
+
+## Unknown Location Strategy
+
+由于部分算力数据源不会直接提供经纬度，未知位置补全不能只依赖“继续找 API 字段”。
+更稳妥的方式是做成一条分层富化链路，而不是单一猜测规则。
+
+推荐按下面优先级推进：
+
+1. 直接源信息
+
+- 源记录显式给出 `latitude / longitude`
+- 源记录给出 `city / region / facility / campus / operator`
+- 源页面详情、内嵌 JSON、结构化元数据、新闻稿链接里能抽出地点线索
+
+2. 名称与机构归一化
+
+- 建立 `canonical_name / aliases / operator / facility` 归一化表
+- 把 `cluster name`、`operator`、`campus name` 归一到同一个实体
+- 优先解决同一对象多写法导致的命中失败，而不是先扩大猜测范围
+
+3. 本地位置注册表
+
+- 用仓库内可维护的 registry 保存高价值对象的位置知识
+- 每条记录至少包含：`canonical_name`、`aliases`、`operator`、`country`、`region`、`city`、`lat`、`lon`、`confidence`、`source_note`
+- 转换层优先读取 registry，避免地点知识长期散落在转换代码里
+
+4. 分层回退定位
+
+- `precise`
+- `estimated_site`
+- `estimated_city`
+- `estimated_region`
+- `estimated_national_hub`
+- `estimated_country`
+
+这里建议把“国家内主要算力城市”作为国家质心之前的一层。
+例如没有美国精确位置时，优先考虑已知的主要算力/数据中心城市候选，而不是直接落在几何质心。
+
+5. 候选证据富化
+
+- 如果源 API 无地点信息，可以允许采集链路读取公开辅助证据
+- 例如机构官网、数据中心介绍页、新闻稿、百科型页面、公开 PDF
+- 但只提取“地点线索”，不把外部页面上的经纬度当真值直接写回
+
+6. 人工校验闭环
+
+- 对高价值且仍然未知的对象输出待核验清单
+- 把人工确认结果回写到位置注册表
+- 后续采集继续优先复用这层人工确认结果
+
+### Additional Solution Paths
+
+除了静态映射表，还可以考虑下面这些办法：
+
+- 基于国家和运营方建立“主要园区候选集”，用稳定散列把同国未知节点分散到若干可信城市，而不是全部压到一个点
+- 基于数据中心/云厂商公开 region 列表建立 `operator -> city set` 候选映射，用于云 GPU 集群类对象
+- 把“估算依据”结构化，例如 `matched_alias`、`matched_operator`、`matched_city_text`、`fallback_country_hub`
+- 给位置补全增加 `last_verified_at`，便于后续按时间重新校验老旧映射
+- 单独维护“不可可靠定位”状态；这类对象仍可在国家级聚合统计中出现，但可以允许用户在地图上过滤掉
+- 后续如果你们愿意投入更多，可把这条链路做成小型 enrichment pipeline，而不是仅在 API 转换时临时判断
+
+## Non-Goals
+
+第一阶段不建议做这些内容：
+
+- 不复制 BGP 巡航模式到算力中心
+- 不先做复杂实时 websocket 推送
+- 不先引入独立 `compute_center_incident` 一类模型
+- 不先做全量 AI 分析面板
+
+原因是算力中心的第一需求是“被看清楚”，不是“被实时播报”。
+但“被看清楚”不等于“只显示精确坐标对象”。
+对于没有精确经纬度、但能推测到国家或区域级位置的算力中心，应优先以上图并标注估算状态的方式处理，而不是直接在地图上消失。
+
+## Acceptance Checklist
+
+- 后端存在统一的算力中心 GeoJSON 出口
+- Earth 有独立算力图层模块，而不是散落在 `main.js`
+- 页面上有清晰的算力开关、图例和统计
+- `supercomputer` 和 `gpu_cluster` 在视觉和详情上都可区分
+- 估算位置对象在地图和详情中都有明确状态提示
+- 现有 BGP / 海缆 / 卫星功能无回归
+- 代码结构上为后续专题页和关系分析留出了明确扩展点
+
+## Summary
+
+这项工作的本质不是“再多画几个点”。
+
+它应该把算力中心从已有数据源，升级成与 BGP 同级的 Earth 观测主题：
+
+- 有独立语义
+- 有独立图层
+- 有独立交互
+- 有后续分析扩展能力
+
+推荐先完成 Phase 1，把算力中心做成真正可用的 Earth 一级模块，再继续推进关系层和专题页。

+# Earth Mobile Drawer UI Plan
+
+## 背景
+
+当前 Earth 移动端已经补上了基础触控能力，例如：
+
+- 单指拖拽旋转地球
+- 双指缩放
+- 点击阈值和基础事件隔离
+
+但移动端 UI 仍然存在一个根本问题：
+
+它还在沿用桌面 HUD 的内容切分方式，只是把原来的 panel、modal、toolbar 改位置、改层级、改容器。这样虽然能快速复用旧代码，但手机端体验仍然是生硬的，因为：
+
+- 信息密度和结构是按桌面设计的
+- 面板标题、关闭、折叠、开关项是桌面心智，不是手机心智
+- 很多内容只是“被塞进抽屉”，而不是为抽屉重新设计
+- 设置里仍然带有“显示/隐藏某些 panel”的思路，但移动端本来就不应该存在那些独立 panel
+
+因此本计划进一步收紧：
+
+移动端不只是“底部抽屉化”，而是**重新设计一套 fit 抽屉体系的 mobile-first UI**。
+
+## 新目标
+
+1. 手机端不再使用现有 `toolbar` 作为主入口。
+2. 手机端不再使用现有独立 `panel / modal / sheet` 作为直接 UI 单元。
+3. 手机端统一采用“底部抽屉 + 顶部标题 + tab 切换 + 卡片内容”的单前景模式。
+4. 抽屉内部每个 tab 页面都按移动端重新设计内容结构，而不是直接复用旧 panel 结构。
+5. 设置页移除“显示/隐藏 panel”的桌面遗留配置。
+6. 媒体页拆成两个移动端页面：`新闻` 与 `TV`，都归入抽屉体系。
+7. 桌面端保持现有 HUD 体系，不回退。
+
+## 核心原则
+
+### 1. 只复用数据和状态，不复用桌面 UI 结构
+
+可复用：
+
+- 图层注册表
+- 搜索结果数据
+- BGP / 海缆 / 卫星详情数据
+- 媒体数据
+- 旋转、缩放、选择、高亮等运行时状态
+
+不直接复用：
+
+- 桌面 panel DOM 结构
+- 桌面 panel header / close / collapse 交互
+- 桌面 settings 项里的“显示某 panel”逻辑
+- 桌面媒体面板布局
+
+### 2. 抽屉是唯一主前景层
+
+移动端同一时刻只有一个主前景层：底部抽屉。
+
+抽屉内部切换内容页，而不是多个悬浮层互相覆盖。
+
+### 3. 每个 tab 都是移动端页面，而不是 panel 容器
+
+抽屉中的每一项都应视为一个移动端子页面：
+
+- 有自己的标题
+- 有自己的内容层次
+- 有自己的滚动区域
+- 有自己的主操作
+
+而不是简单挂一个旧面板进去。
+
+### 4. 移动端状态提示不占据屏幕正中
+
+桌面端当前很多通知、状态提示、胶囊消息更适合在屏幕上方居中出现，但移动端不应继续沿用这套布局。
+
+移动端统一改为：
+
+- 通知栏放在右上角安全区
+- 胶囊提示放在右上角堆叠
+- 不遮挡地球中心视野
+- 不与底部抽屉主交互区冲突
+
+## 交互模型
+
+### 默认态
+
+移动端默认只显示：
+
+- 地球主画布
+- 底部半露出的抽屉头部
+
+不再单独显示上箭头按钮。
+
+### 展开态
+
+用户从底边直接上拉抽屉，或点击抽屉头部展开。
+
+展开后显示：
+
+- 当前页面标题
+- tab 导航
+- 当前页面内容
+
+### 收起态
+
+用户下拉抽屉头部收起，或点击背景收起。
+
+## 信息架构
+
+移动端抽屉内的一级页面重定为：
+
+1. 图层
+2. 搜索
+3. 态势
+4. 新闻
+5. TV
+6. 设置
+7. 详情（按需出现，不固定常驻 tab）
+
+其中 `新闻` 和 `TV` 不再共享同一个移动端媒体面板。
+
+## 页面重设计要求
+
+### 图层页
+
+目标：
+
+- 成为移动端最核心的控制页
+- 强调快速开关，不强调桌面 panel 感
+
+内容建议：
+
+- 顶部摘要：当前已启用图层数量
+- 图层列表卡片
+- 每个图层项只保留：
+  - 图标
+  - 中文名
+  - 英文副标题
+  - 开关
+- 去掉桌面式 header / collapse / close 结构
+
+### 搜索页
+
+目标：
+
+- 成为抽屉中的完整搜索页
+- 避免看起来像桌面 modal 被塞进抽屉
+
+内容建议：
+
+- 顶部搜索输入框
+- 搜索提示文案
+- 结果列表
+- 结果项更适合手指点击
+- 结果点击后：
+  - 聚焦地球对象
+  - 自动切换到详情页
+
+### 态势页
+
+目标：
+
+- 合并原来的 `stats + legend` 思路
+- 成为移动端全局态势页
+
+内容建议：
+
+- 顶部核心统计卡
+  - 海缆数量
+  - 登陆点数量
+  - 卫星数量
+  - BGP 事件数量
+- 当前关注层图例
+- BGP 状态摘要
+- 不再出现独立 legend 面板和独立 stats 面板
+
+### 新闻页
+
+目标：
+
+- 从原媒体面板中拆出单独的移动端新闻页
+
+内容建议：
+
+- 当前区域焦点
+- 新闻源数量
+- 新闻卡片列表
+- 卡片内显示标题、来源、时间、区域
+- 外链操作更清晰
+
+### TV 页
+
+目标：
+
+- 从原媒体面板中拆出单独的移动端 TV 页
+
+内容建议：
+
+- 顶部频道选择
+- 直播状态
+- 当前频道说明
+- 视频播放器区域
+- 刷新和外链按钮
+
+不再保留桌面式“新闻/TV tab 共处一个 panel”的结构。
+
+### 设置页
+
+目标：
+
+- 只保留对移动端仍有意义的系统配置
+
+必须移除：
+
+- 图层控制 panel 显示/隐藏
+- 图例 panel 显示/隐藏
+- 全球态势 panel 显示/隐藏
+- 媒体 panel 显示/隐藏
+
+保留项建议：
+
+- 旋转模式
+- 日夜模式
+- 地球默认大小
+- 地形透明度
+- 系统入口
+
+原因：
+
+移动端已经没有这些独立 panel 了，所以继续保留这些开关会制造错误心智。
+
+### 详情页
+
+目标：
+
+- 成为海缆 / BGP / 卫星对象的统一移动端详情页
+
+内容建议：
+
+- 标题区
+- 类型标签
+- 关键属性列表
+- 相关对象摘要
+- 相关图层或态势提示
+
+行为建议：
+
+- 点击对象后自动切入详情页
+- 搜索结果点击后也切入详情页
+
+## 阶段重定义
+
+### 阶段 2：抽屉壳层
+
+目标：
+
+1. 实现底部抽屉基本壳层。
+2. 支持上拉展开、下拉收起、背景点击关闭。
+3. `mobile` 模式下隐藏旧 toolbar。
+4. `mobile` 模式下不再直接显示旧 panel。
+
+完成标准：
+
+1. 手机端只有地球主视图和抽屉。
+2. 抽屉开合稳定。
+
+### 阶段 3：基础页面重做
+

+# 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
+

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

+# Earth 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

+# 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：

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