-# /docs — 技术文档写入工作流
+# /docs — Documentation Workflow
 
-## 目标
+## Goal
 
-根据当前 git 变更（或用户指定主题）在 `docs/technical/zh/` 中写入或更新技术文档，记录**为什么**这样做，而不只是记录做了什么。
+Create or update documentation that explains why a change exists, how it behaves, and what maintainers need to know. Keep this command generic. Repository-specific coverage rules live in the repository and must be loaded separately.
 
-## 执行步骤
+## Repository Rules
 
-### Step 1 — 理解变更范围
+Before deciding scope, check whether the repository has a documentation rules file:
 
 ```bash
-git diff HEAD --stat          # 变更文件一览
-git diff HEAD --name-only     # 变更文件列表
-git log --oneline -10         # 近期 commit 上下文
+test -f docs/documentation-coverage-rules.md && sed -n '1,240p' docs/documentation-coverage-rules.md
 ```
 
-若 `$ARGUMENTS` 指定了主题，优先聚焦该主题；否则从文件列表和 diff stat 推断变更主题。不要默认读取完整仓库 diff；只对决定文档主题所需的文件读取 focused diff：
+If it exists, apply it as the project-specific coverage checklist. If it does not exist, continue with the generic workflow below.
+
+## Workflow
+
+### Step 1 — Understand The Change
+
+```bash
+git diff HEAD --stat
+git diff HEAD --name-only
+git log --oneline -10
+rg --files docs
+```
+
+If `$ARGUMENTS` specifies a topic, focus on that topic. Otherwise infer the documentation topic from the changed files. Do not read the full repository diff by default; inspect focused files only:
 
 ```bash
 git diff HEAD -- <path>
 rg -n "class |def |function |export |router|@router|interface |type " <path>
 ```
 
-### Step 2 — 确认文档范围
+### Step 2 — Decide Scope
 
-分析变更，判断：
+- Prefer updating an existing relevant document over creating a duplicate.
+- Use one document for one coherent topic.
+- Split documents only when the change crosses meaningful domains.
+- Keep filenames lowercase and hyphenated.
+- Apply the repository-specific rules file before writing.
 
-1. **应写几篇文档**：单一主题写一篇，跨领域变更可拆分（如后端性能优化 + 运维启动脚本分开写）
-2. **是新建还是更新**：检查 `docs/technical/zh/` 中是否已有相关文档
-3. **文档命名**：按 `领域-主题-副题.md` 格式，全小写，用连字符，如：
-   - `backend-datasources-api-performance.md`
-   - `ops-planet-sh-startup.md`
-   - `earth-bgp-context.md`
+For ambiguous or large documentation changes, briefly state the intended doc plan before editing. For clear small changes, proceed directly.
 
-```bash
-ls docs/technical/zh/          # 查看现有文档
+### Step 3 — Write
+
+Explain:
+
+- Background/problem: what was wrong or missing before.
+- Core design decisions and rationale.
+- Operational or user-facing impact.
+- Relevant code paths, only when useful for future maintainers.
+
+Style:
+
+- Follow the repository’s existing language and heading conventions.
+- Use fenced code blocks with language tags.
+- Prefer tables for comparisons or parameter lists.
+- Keep snippets concise and relevant.
+
+### Step 4 — Verify
+
+- Read the completed docs once for clarity and stale statements.
+- Verify referenced paths exist with `test -e` or `rg --files`.
+- Run applicable checks from `docs/documentation-coverage-rules.md`.
+- Check Markdown links use readable user-facing titles unless repository rules allow otherwise.
+
+### Step 5 — Report
+
+Summarize changed docs and verification:
+
+```md
+Updated:
+- path/to/doc.md — what changed
+
+Verified:
+- checks that passed
+- checks that could not be run, if any
 ```
 
-**先输出写作计划供用户确认**（若变更明确且范围小，可直接执行）：
+## Hard Constraints
 
-```
-文档计划：
-  新建：docs/technical/zh/ops-planet-sh-startup.md — planet.sh 启动性能优化
-  更新：docs/technical/zh/backend-datasources-api-performance.md — 补充并行化细节
-```
-
-### Step 2.5 — 覆盖范围检查
-
-写文档前必须按变更类型检查配套文档，不要只更新一篇专题文档：
-
-- 用户可见流程变化：更新 `docs/technical/zh/manual.md`，通常也更新 `docs/technical/zh/quickstart.md`。
-- `manual.md`、`quickstart.md` 这类用户手册存在英文版时，同步更新 `docs/technical/en/...`，至少避免英文版与中文版互相矛盾。
-- 控制台页面职责、路由入口、表格/抽屉/设置页行为变化：更新 `docs/technical/zh/frontend-admin-frontend-context.md`。
-- Earth 前端行为、HUD、巡航、图层、图例、交互变化：更新 `docs/technical/zh/earth-frontend-context.md`。
-- 新增 Earth 图层、调整 `renderOrder`、半径/高度偏移、深度策略、拾取策略、legend mode、图层面板顺序或启动加载顺序：更新 `docs/technical/zh/earth-render-layer-order.md`。
-- Earth 图层视觉样式、颜色、图例符号语义变化：若影响样式索引，同步更新 `docs/technical/zh/earth-layer-style-reference.md`。
-- 采集器、数据源、凭证、设置页、连接检查、scheduler、后端 API 变化：更新相关后端文档，优先检查 `docs/technical/zh/backend-collectors.md` 和 datasource/settings 专题文档。
-- 如果某个旧 plan 的假设已经被当前实现推翻，在对应 `docs/plans/*.md` 增加现状修正或更新该段，不要让计划文档继续给出相反方向。
-- 新增 technical 文档后，如果需要被发现，更新 `docs/technical/zh/README.md`。
-- 对本次变更提取旧词做 stale search，例如旧 tab 名、旧路由职责、旧认证假设、改名前 UI 文案：
-
-```bash
-rg -n "旧文案|旧路由职责|旧认证假设" docs/technical docs/plans
-```
-
-### Step 3 — 写文档
-
-遵循以下原则：
-
-**记录 WHY，不只记录 WHAT**
-- 好：`将戳文件从 /tmp 移到 ~/.cache/planet/，因为 WSL 重启后 /tmp 被清空`
-- 差：`修改了 AI_PROVIDER_BUILD_STAMP_FILE 的值`
-
-**必须包含的内容**：
-- 背景/问题：改动之前存在什么问题，为什么要改
-- 核心设计决策及其理由
-- 关键代码片段（用 diff 或 before/after 展示）
-- 相关文件列表
-
-**格式要求**：
-- 使用 `##` 和 `###` 分级，不要超过三级
-- 代码块注明语言（python / bash / typescript / sql）
-- 表格用于对比多个选项或列出参数
-- 中文写作，技术术语保留英文原文
-- `docs/technical/zh/` 中的文档不得用英文原文占位；如果存在 `docs/technical/en/` 对应文件，禁止逐字复制成中文文件
-- 中文文档内部链接应指向 `docs/technical/zh/...`，除非明确引用英文专属文档
-
-**文档结构模板**：
-
-```markdown
-# 标题（说明做了什么）
-
-## 背景
-
-为什么要做这个改动，改动前存在什么问题。
-
-## 核心变更
-
-### 子主题一

-
-### 子主题二
-
-...
-
-## 相关文件
-
-- `path/to/file.py` — 简短说明
-```
-
-### Step 4 — 验证
-
-- 读一遍写好的文档，确认逻辑清晰、代码片段无明显错误
-- 用 `rg --files` 或 `test -e` 确认文档中的文件路径在项目中真实存在，避免凭记忆判断：
-- 检查中文文档没有误复制英文版：
-
-```bash
-python - <<'PY'
-from pathlib import Path
-same = []
-for en in sorted(Path("docs/technical/en").glob("*.md")):
-    zh = Path("docs/technical/zh") / en.name
-    if zh.exists() and en.read_text() == zh.read_text():
-        same.append(en.name)
-if same:
-    raise SystemExit("identical en/zh docs: " + ", ".join(same))
-print("no identical en/zh docs")
-PY
-```
-
-- 检查中文文档内部链接没有继续指向无语言目录：
-
-```bash
-rg -n "/home/ray/dev/linkong/planet/docs/technical/(?!zh|en)" docs/technical/zh --pcre2
-```
-
-```bash
-# 对文档中提到的关键路径做快速验证
-ls <mentioned_paths>
-```
-
-如需检查大量链接，优先用确定性提取：
-
-```bash
-rg -n "\]\(([^)]+)\)" docs/technical/zh/<doc>.md
-```
-
-### Step 5 — 完成确认
-
-输出摘要：
-
-```
-✓ 新建：docs/technical/zh/ops-planet-sh-startup.md（约 xxx 字）
-✓ 更新：docs/technical/zh/backend-datasources-api-performance.md
-```
-
-## 注意事项
-
-- 不要写流水账式的"改了 A、改了 B、改了 C"，要写改动背后的约束和权衡
-- 不要在文档中引用 PR 号、issue 号、或当前对话——这些会随时间失效
-- 代码片段保持简洁，只保留说明问题的关键部分，省略无关样板代码
-- 如果某个变更已有文档记录，优先在原文档中追加，而不是新建
-- 文档是给未来的开发者看的，假设读者熟悉项目但不了解这次改动的背景

+2. Decide scope:
 
-- Use one document for one coherent topic.
-- Split documents when the changes cross meaningful domains, such as backend performance and ops startup behavior.
 - Prefer updating an existing relevant doc over creating a duplicate.
-- Name new files as lowercase hyphenated `domain-topic-detail.md`, for example:
-  - `backend-datasources-api-performance.md`
-  - `ops-planet-sh-startup.md`
-  - `earth-bgp-context.md`
+- Use one document for one coherent topic.
+- Split documents only when changes cross meaningful domains.
+- Keep filenames lowercase and hyphenated.
 
-3. Apply the documentation coverage checklist before writing:
+3. Write the doc:
 
-- User-visible workflow changes must update `docs/technical/zh/manual.md` and usually `docs/technical/zh/quickstart.md`.
-- If an English counterpart exists for user-facing docs such as `manual.md` or `quickstart.md`, update `docs/technical/en/...` enough that it does not contradict the Chinese source.
-- Control console page responsibility changes must update `docs/technical/zh/frontend-admin-frontend-context.md`.
-- Earth frontend behavior changes must update `docs/technical/zh/earth-frontend-context.md`.
-- Earth layer additions, `renderOrder`, altitude/radius offsets, depth strategy, pointer picking, legend modes, or layer panel/startup ordering must update `docs/technical/zh/earth-render-layer-order.md`.
-- Earth layer visual style or legend symbol/color semantics should also update `docs/technical/zh/earth-layer-style-reference.md` when that reference is affected.
-- Collector, datasource, credential, settings, connectivity, scheduler, or API changes must update the relevant backend docs, especially `docs/technical/zh/backend-collectors.md` and any datasource/settings-specific doc.
-- When a change turns an old plan assumption into current behavior, update the relevant `docs/plans/*.md` with a status note instead of leaving contradictory instructions.
-- If adding a new technical document, add it to `docs/technical/zh/README.md` when it should be discoverable from the technical docs index.
-- Search docs for stale terms introduced by the change, for example old tab names, old route responsibilities, obsolete auth assumptions, or renamed UI labels.
+- Explain background/problem, design decisions, constraints, and operational impact.
+- Keep code snippets short and directly relevant.
+- List related files only when they help future maintainers navigate.
+- Use the repository’s existing language, heading style, and naming conventions.
 
-4. Write the doc in Chinese:
+4. Verify:
 
-- Write Chinese prose for `docs/technical/zh/`.
-- Keep technical identifiers, API paths, config keys, code symbols, and standard product names in English where appropriate.
-- Use `##` and `###` headings; avoid going deeper than three levels.
-- Use fenced code blocks with language tags.
-- Use tables when comparing options or listing parameters.
-
-5. Required content:
-
-- Background/problem: what was wrong before and why the change was needed.
-- Core design decisions and rationale.
-- Key code snippets, preferably before/after or focused excerpts.
-- Related files and what each file contributes.
-
-6. Verification:
-
-- Read the completed doc and check that the reasoning is clear.
-- Verify important referenced paths exist.
-- Use `rg --files` or `test -e` for path existence instead of relying on memory.
-- Run a quick duplicate-language check when editing bilingual docs:
-
-```bash
-python - <<'PY'
-from pathlib import Path
-same = []
-for en in sorted(Path("docs/technical/en").glob("*.md")):
-    zh = Path("docs/technical/zh") / en.name
-    if zh.exists() and en.read_text() == zh.read_text():
-        same.append(en.name)
-if same:
-    raise SystemExit("identical en/zh docs: " + ", ".join(same))
-print("no identical en/zh docs")
-PY
-```
-
-Also check that Chinese docs do not link to the old language-less technical docs path:
-
-```bash
-rg -n "/home/ray/dev/linkong/planet/docs/technical/(?!zh|en)" docs/technical/zh --pcre2
-```
-
-This command should return no matches.
-
-If checking many links, prefer deterministic extraction:
-
-```bash
-rg -n "\]\(([^)]+)\)" docs/technical/zh/<doc>.md
-```
-
-Also run focused stale-term searches derived from the change, for example:
-
-```bash
-rg -n "old label|old route purpose|obsolete provider assumption" docs/technical docs/plans
-```
+- Read the completed doc once for clarity and stale statements.
+- Verify important referenced paths exist with `test -e` or `rg --files`.
+- Run repository-specific doc checks from `docs/documentation-coverage-rules.md` when present.
+- For Markdown links, check that user-facing titles are readable and not raw filenames unless the repository rules allow it.
 
 ## Hard Constraints
 
-- A file under `docs/technical/zh/` must not be an English source file copied as a placeholder.
-- Do not leave a Chinese doc with only an English title and English first-screen content.
-- When an English counterpart exists in `docs/technical/en/`, never duplicate it byte-for-byte into `docs/technical/zh/`.
-- Internal links inside `docs/technical/zh/` should point to `docs/technical/zh/...` for Chinese docs, unless intentionally linking to an English-only file.
-- Do not reference PR numbers, issue numbers, or the current conversation.
-- Do not write changelog-style lists like "changed A, changed B, changed C" without the constraints and tradeoffs behind those changes.
-- Keep code snippets concise and relevant.
+- Do not leave placeholder docs or copied source text pretending to be documentation.

+"""Compute-center location resolver, built on the shared location pipeline.
+
+This module is a thin domain wrapper that wires up
+:mod:`app.services.location` for compute centers:
+
+    SourceCoordinates
+
+The online Nominatim step is intentionally reserved for the user-triggered
+``collect-location`` flow. The regular GeoJSON endpoint runs during Earth
+startup, so it must stay local and deterministic.
+
+For the full design and the reason behind the abstraction (compute centers,
+BGP collectors, BGP events, and future entities all share one pipeline),
+see ``docs/plans/location-resolver-shared-pipeline-plan.md``.
+
+The ``ComputeCenterLocation`` dataclass and the public function signatures are
+preserved verbatim so existing callers and tests do not need to change.

+
+官方入口：https://aisstream.io/
+
+1. 打开 AISStream 官网，按当前页面指引注册或登录账号。
+2. 在账号/API 管理页面创建或复制你的 API Key。
+3. 先确认当前账号额度、使用条款和可订阅区域。实时 AIS 流量可能很大，不建议一开始订阅全球范围。
+4. 回到 Planet 的 `设置 -> 采集器设置 -> AISStream 实时船舶`。
+5. 在 `AISStream 凭证` 中填入 API Key。
+6. Endpoint 通常保持默认：`wss://stream.aisstream.io/v0/stream`。
+7. 按需配置 `Bounding Boxes JSON` 和 `消息类型`。
+8. 点击连接测试，确认系统能读取凭证且 WebSocket endpoint 格式有效。
+9. 保存采集器设置后再运行 `aisstream_vessels` collector。
+
+### 推荐配置
+
+默认消息类型：
+
+```json
+["PositionReport", "ShipStaticData"]
+```
+
+默认 Bounding Boxes 示例：
+
+```json
+[[[-90, -180], [90, 180]]]
+```
+
+这个示例表示全球范围。实际使用时建议先改成较小区域，降低消息量和处理压力。
+
+### 请求规则
+
+- Endpoint：`wss://stream.aisstream.io/v0/stream`
+- 传输方式：WebSocket
+- API Key 放在订阅 payload 中，不放在 HTTP header。
+- Planet 会把 AISStream 标记为 `delivery_mode = realtime_stream`、`transport = websocket`。
+- AISStream collector 只写入 AIS raw observations，不直接覆盖最终船只展示表。
+
+### 常见排查
+
+- `未找到凭证`：确认 API Key 已保存到采集器设置，或设置了 `AISSTREAM_API_KEY` 环境变量 / `~/.zshrc`。
+- `endpoint 必须是 ws:// 或 wss://`：AISStream 是 WebSocket 流接口，不要填普通 `https://` API 地址。
+- 采集量过大：缩小 `Bounding Boxes JSON`，减少 `message_types`，或降低单次最大消息数。
+- 没有船只数据：确认订阅区域内确实有 AIS 活动，并检查 API Key 当前额度和权限。
+- 连接中断：实时流可能受网络和上游限流影响，collector 会记录源健康状态供聚合服务回退。

+# Documentation Coverage Rules
+
+This file contains Planet-specific documentation coverage rules. Documentation skills and agents should read this file before deciding which docs to update. Keep tool-specific workflow in skills; keep product and repository rules here.
+
+## Scope Rules
+
+- User-visible workflow changes must update `docs/technical/zh/manual.md` and usually `docs/technical/zh/quickstart.md`.
+- If an English counterpart exists for user-facing docs such as `manual.md` or `quickstart.md`, update `docs/technical/en/...` enough that it does not contradict the Chinese source.
+- Control console page responsibility changes must update `docs/technical/zh/frontend-admin-frontend-context.md`.
+- Earth frontend behavior changes must update `docs/technical/zh/earth-frontend-context.md`.
+- Earth layer additions, `renderOrder`, altitude/radius offsets, depth strategy, pointer picking, legend modes, or layer panel/startup ordering must update `docs/technical/zh/earth-render-layer-order.md`.
+- Earth layer visual style or legend symbol/color semantics should also update `docs/technical/zh/earth-layer-style-reference.md` when that reference is affected.
+- Collector, datasource, credential, settings, connectivity, scheduler, or API changes must update the relevant backend docs, especially `docs/technical/zh/backend-collectors.md` and any datasource/settings-specific doc.
+- When a change turns an old plan assumption into current behavior, update the relevant `docs/plans/*.md` with a status note instead of leaving contradictory instructions.
+- Search docs for stale terms introduced by the change, for example old tab names, old route responsibilities, obsolete auth assumptions, or renamed UI labels.
+
+## Public Docs Rules
+
+- If adding a new technical document, add it to `docs/technical/zh/README.md` when it should be discoverable from the technical docs index.
+- If a technical document should be visible in the public Docs page or linked from a technical README, register it in `frontend/src/pages/Docs/docs-content.ts` under `DOCS_METADATA`. Files under `docs/technical/{zh,en}/` are not automatically routable.
+- For every public technical doc, keep the bilingual file pair in sync by filename: `docs/technical/zh/<name>.md` and `docs/technical/en/<name>.md`. If content is intentionally Chinese-only or English-only, state that intentionally in the final note.
+- Public docs should use readable link text, not raw filenames such as `manual.md`.
+
+## Credential Collector Rules
+
+- Any built-in collector marked `requires_credentials: true` and `credential_status: supported` must have:
+  - a `credential_provider` in `backend/app/core/datasource_defaults.py`;
+  - a default credential guide in `backend/app/services/credential_guides.py`;
+  - a supported connectivity provider in `backend/app/services/datasource_connectivity.py`;
+  - settings UI guidance or a credential form in `frontend/src/pages/Settings/Settings.tsx`;
+  - a regression test that fails if the guide/provider is missing.
+
+## Recommended Checks
+
+Run the checks that match the affected docs.
+
+### Duplicate Bilingual Docs
+
+```bash
+python - <<'PY'
+from pathlib import Path
+same = []
+for en in sorted(Path("docs/technical/en").glob("*.md")):
+    zh = Path("docs/technical/zh") / en.name
+    if zh.exists() and en.read_text() == zh.read_text():
+        same.append(en.name)
+if same:
+    raise SystemExit("identical en/zh docs: " + ", ".join(same))
+print("no identical en/zh docs")
+PY
+```
+
+### Language-Less Technical Links
+
+```bash
+rg -n "/home/ray/dev/linkong/planet/docs/technical/(?!zh|en)" docs/technical/zh --pcre2
+```
+
+This should return no matches.
+
+### Public Docs Registry
+
+```bash
+python - <<'PY'
+import re
+from pathlib import Path
+
+metadata = Path("frontend/src/pages/Docs/docs-content.ts").read_text()
+known = set(re.findall(r"'([^']+\.md)':\s*\{", metadata))
+known.add("README.md")
+
+missing = []
+for readme in [Path("docs/technical/zh/README.md"), Path("docs/technical/en/README.md")]:
+    if not readme.exists():
+        continue
+    for href in re.findall(r"\]\(([^)]+\.md)\)", readme.read_text()):
+        path = Path(href)
+        if "docs/technical/" not in href:
+            continue
+        filename = path.name
+        if filename not in known:
+            missing.append(f"{readme}: {filename}")
+
+if missing:
+    raise SystemExit("docs README links missing DOCS_METADATA: " + ", ".join(missing))
+print("docs README links are whitelisted")
+PY
+```
+
+### Public Bilingual Pairs
+
+```bash
+python - <<'PY'
+import re
+from pathlib import Path
+
+metadata = Path("frontend/src/pages/Docs/docs-content.ts").read_text()
+filenames = sorted(set(re.findall(r"'([^']+\.md)':\s*\{", metadata)) - {"README.md"})
+missing = []
+for filename in filenames:
+    for lang in ("zh", "en"):
+        path = Path("docs/technical") / lang / filename
+        if not path.exists():
+            missing.append(str(path))
+if missing:
+    raise SystemExit("missing bilingual docs: " + ", ".join(missing))
+print("public docs have zh/en file pairs")
+PY
+```
+
+### Raw Filename Link Titles
+
+```bash
+rg -n "\[[^]]+\.md\]\(" docs/technical/zh docs/technical/en
+```
+
+This should return no matches for polished public docs.

+# Lightweight Agent Orchestrator and WebSearch Evidence Plan
+
+## Overview
+
+Planet should not turn `aiprovider` into a general-purpose agent runtime.
+
+`aiprovider` should remain the model gateway:
+
+- provider compatibility
+- protocol adaptation
+- model authentication
+- request and response normalization
+
+Agent behavior belongs in the backend, where Planet already owns business state,
+permissions, persistence, evidence records, and operator workflows.
+
+The recommended direction is a lightweight backend Agent Orchestrator with a
+controlled tool layer. The first version should use fixed workflows instead of a
+free-form tool-calling loop.
+
+
+## Architecture Decision
+
+Use this boundary:
+
+```text
+aiprovider = model adapter only
+backend Agent = task orchestration + tools + evidence + policy + business rules
+```
+
+This keeps model transport separate from Planet-specific behavior. It also lets
+OpenAI, MiniMax, Anthropic-compatible providers, Ollama, and later providers all
+reuse the same backend tools.
+
+Recommended module shape:
+
+```text
+backend/app/services/
+  ai/
+    agent_orchestrator.py
+    tool_registry.py
+    prompts.py
+    schemas.py
+  ai_tools/
+    web_search.py
+    web_fetch.py
+    geo_resolve.py
+    internal_data_query.py
+    incident_query.py
+    evidence_store.py
+  situation/
+    bgp_analyzer.py
+    risk_scoring.py
+    event_correlator.py
+    alert_policy.py
+
+aiprovider/
+  provider_service.py
+  main.py
+```
+
+
+## Phase 1: Controlled Workflow Agent
+
+The first implementation should not be a full OpenClaw/Codex-style agent loop.
+Planet's immediate needs are better served by explicit workflows:
+
+1. `tutorial_refresh`
+2. `geo_correction`
+3. `situation_brief`
+
+Each workflow should:
+
+1. collect evidence with backend tools
+2. normalize and store evidence
+3. call `AIProviderClient` through the configured global provider/model/key
+4. validate the result with Pydantic schemas
+5. return a proposal, candidate, or brief instead of directly mutating critical state
+
+For location correction, the flow should be:
+
+```text
+object name / type / current coordinate / description
+  -> web_search
+  -> web_fetch for selected results
+  -> geo_resolve for city/site coordinates
+  -> LLM structured extraction
+  -> schema validation and confidence scoring
+  -> pending review candidate
+```
+
+The LLM output must be constrained to a schema such as:
+
+```json
+{
+  "object_id": "string",
+  "object_type": "datacenter|ixp|submarine_cable|asn|city|facility|satellite",
+  "current_location": {
+    "lat": 0,
+    "lon": 0
+  },
+  "suggested_location": {
+    "lat": 0,
+    "lon": 0
+  },
+  "confidence": 0.82,
+  "reason": "short evidence-backed explanation",
+  "evidence": [
+    {
+      "title": "source title",
+      "url": "https://example.com/source",
+      "quote": "short supporting excerpt",
+      "retrieved_at": "2026-05-10T00:00:00Z"
+    }
+  ],
+  "needs_human_review": true
+}
+```
+
+The LLM may generate a suggestion, but it must not directly write final
+coordinates into the dimension tables.
+
+
+## Phase 2: Backend Tool Registry
+
+Add a small Python tool interface in the backend:
+
+```python
+class ToolResult(BaseModel):
+    ok: bool
+    data: Any = None
+    error: str | None = None
+    evidence: list[dict] = []
+```
+
+Register tools through a backend registry:
+
+```text
+web_search
+web_fetch
+geo_resolve
+internal_data_query
+incident_query
+evidence_store
+```
+
+Do not put WebSearch inside `aiprovider`.
+
+Reasons:
+
+- search is a business tool, not a model-provider feature
+- search evidence must be stored and audited by the backend
+- different LLM providers should share the same search pipeline
+- Planet may switch between Tavily, Brave, Exa, SearXNG, or MiniMax MCP without
+  changing model transport
+
+The first WebSearch implementation should be an HTTP evidence provider. Tavily is
+the recommended first default because it is simple to call from the existing
+`httpx` backend stack and returns LLM/RAG-friendly search results. The interface
+should remain provider-neutral so Brave, Exa, SearXNG, or MiniMax MCP can be
+added later.
+
+WebSearch configuration should live under PostgreSQL `system_settings` with the
+rest of external integrations:
+
+```text
+external_integrations.web_search
+  enabled
+  provider
+  api_key
+  base_url
+  max_results
+  timeout_seconds
+```
+
+Secret resolution should follow the existing settings pattern:
+
+1. saved PostgreSQL secret
+2. provider-specific environment variable, for example `TAVILY_API_KEY`
+3. generic fallback `WEB_SEARCH_API_KEY`
+
+### Common WebSearch Providers
+
+The first implementation should model WebSearch as a provider-specific adapter
+behind one internal interface:
+
+```text
+SearchEvidenceProvider.search(query, max_results, domains, freshness_days)
+  -> list[SearchEvidence]
+```
+
+Recommended provider ids and environment variables:
+
+| Provider | Provider id | Env key | Default base URL | Primary use |
+| --- | --- | --- | --- | --- |
+| Tavily | `tavily` | `TAVILY_API_KEY` | `https://api.tavily.com` | Default hosted search for agent/RAG style results |
+| Brave Search API | `brave` | `BRAVE_SEARCH_API_KEY` | `https://api.search.brave.com` | Independent web index and low-level SERP results |
+| SerpAPI | `serpapi` | `SERPAPI_API_KEY` | `https://serpapi.com` | Search-engine-backed SERP data with engine options |
+| Exa | `exa` | `EXA_API_KEY` | `https://api.exa.ai` | Neural/semantic web search and result contents |
+| Firecrawl Search / Scrape | `firecrawl` | `FIRECRAWL_API_KEY` | `https://api.firecrawl.dev` | Search plus page scrape/markdown extraction |
+| SearXNG | `searxng` | optional `SEARXNG_API_KEY` | self-hosted instance URL | Self-hosted metasearch when external search APIs are undesirable |
+
+The normalized configuration should support per-provider defaults while keeping
+one active provider:
+
+```text
+external_integrations.web_search
+  enabled: true
+  default_provider: tavily
+  providers:
+    tavily:
+      base_url: https://api.tavily.com
+      api_key: <secret>
+      max_results: 5
+      search_depth: basic
+      include_answer: false
+      include_raw_content: false
+    brave:
+      base_url: https://api.search.brave.com
+      api_key: <secret>
+      endpoint_path: /res/v1/web/search
+      max_results: 5
+    serpapi:
+      base_url: https://serpapi.com
+      api_key: <secret>
+      endpoint_path: /search.json
+      engine: google
+      max_results: 5
+    exa:
+      base_url: https://api.exa.ai
+      api_key: <secret>
+      endpoint_path: /search
+      max_results: 5
+      include_text: false
+    firecrawl:
+      base_url: https://api.firecrawl.dev
+      api_key: <secret>
+      search_path: /v2/search
+      scrape_path: /v2/scrape
+      max_results: 5
+      scrape_formats: [markdown]
+    searxng:
+      base_url: http://localhost:8080
+      api_key: <optional secret>
+      endpoint_path: /
+      max_results: 5
+      categories: general
+      engines: []
+```
+
+Adapter notes:
+
+- Tavily should call `/search` and normalize title, URL, snippet/content, score,
+  and optional raw content.
+- Brave should call `/res/v1/web/search` and map web results into the same
+  `SearchEvidence` shape.
+- SerpAPI should call `/search.json`, pass `engine`, and normalize organic
+  results. Search-engine-specific fields should remain in provider metadata.
+- Exa should call `/search`; optional result text should be treated as fetched
+  content only when enabled.
+- Firecrawl can be used both as `web_search` and `web_fetch`: `/v2/search`
+  returns result URLs/descriptions and may include scrape options, while
+  `/v2/scrape` can produce markdown for a selected URL.
+- SearXNG should query the configured instance with `q` and `format=json`.
+  Public instances should not be assumed reliable for production; a controlled
+  self-hosted instance is preferred.
+
+The settings UI should expose only provider, base URL, key, max results, and a
+test button in the first version. Provider-specific advanced fields can stay
+collapsed or backend-only until a real workflow needs them.
+
+### Frontend Configuration Window
+
+Add a WebSearch configuration panel to the existing settings page, next to the
+LLM provider configuration. It should behave like the current AI provider secret
+controls: clear configured state, masked preview, explicit show/hide, test
+connection, and save feedback.
+
+First-version visible fields:
+
+```text
+WebSearch Provider
+API Base URL
+API Key
+Max Results
+Timeout Seconds
+Enable WebSearch
+Test Connection
+Save
+```
+
+Provider dropdown options:
+
+```text
+Tavily
+Brave Search API
+SerpAPI
+Exa
+Firecrawl Search / Scrape
+SearXNG
+```
+
+Field behavior:
+
+- Switching provider loads that provider's saved config and masked key preview.
+- Empty key input means keep the existing saved or environment key.
+- Typing a new key replaces only the selected provider's key.
+- Show key reveals the full current input value when the backend reveal endpoint
+  allows it; hide key returns to the prefix-preserving masked preview.
+- The configured badge should only show `已配置` or `未配置`, not repeat the
+  masked key text.
+- `Test Connection` sends the current unsaved draft to the backend and should
+  not require a separate save first.
+- A successful test may save the draft as the new WebSearch default only if the
+  API endpoint is explicitly designed to mirror the AI provider test behavior.
+  Otherwise, test should be read-only and the Save button should persist.
+- Save success and test success must show visible feedback. Failures should show
+  provider-specific but secret-safe error messages.
+
+Provider-specific UI hints:
+
+| Provider | UI hint |
+| --- | --- |
+| Tavily | Good default for agent/RAG style search. |
+| Brave Search API | Uses Brave's independent search index. |
+| SerpAPI | Supports search-engine-specific parameters such as `engine`. |
+| Exa | Good for semantic search and optional result text. |
+| Firecrawl | Can search and scrape pages into markdown. |
+| SearXNG | Requires a reachable self-hosted or trusted instance URL. |
+
+Advanced fields can live in a collapsed section:
+
+```text
+Endpoint Path
+Search Depth
+Engine
+Categories
+Engines
+Include Raw Content
+Scrape Formats
+Domain Allowlist
+```
+
+The first version should keep the UI conservative. It should not expose every
+provider knob until backend workflows use those knobs.
+
+### Web Fetch and Page Extraction
+
+`web_fetch` is separate from `web_search`. Search finds candidate URLs; fetch
+turns selected pages into clean, citable evidence.
+
+Recommended extraction chain:
+
+```text
+1. plain httpx fetch
+2. trafilatura extraction for static HTML
+3. readability extraction as secondary cleanup
+4. Playwright fetch only for allowlisted JS-heavy pages
+5. Firecrawl scrape as hosted fallback when configured
+```
+
+Implementation guidance:
+
+- Use `trafilatura` as the first local extractor because it is Python-native and
+  matches the backend stack.
+- Prefer a Python readability implementation for local cleanup. Do not introduce
+  a Node-only readability dependency for backend fetch.
+- Use Playwright sparingly for JavaScript-rendered pages. It should have domain
+  allowlists, low concurrency, strict timeouts, response size limits, and no
+  automatic form submission or login behavior.
+- Store `content_hash`, `retrieved_at`, final URL, title, extracted text
+  preview, and extractor name in `ai_evidence`.
+- Keep short quotes for UI review, but do not store huge page bodies directly in
+  every task record. Large extracted content should be truncated or stored once
+  by hash.
+
+The local/self-hosted stack should look like this:
+
+```text
+SearXNG
+  -> SearchEvidence URLs
+  -> httpx fetch
+  -> trafilatura / readability
+  -> Playwright only when static extraction fails and the domain is allowed
+  -> normalized evidence
+  -> LLM structured output through AIProviderClient
+```
+
+This route gives Planet a lower-cost and more controllable search path, while
+hosted providers remain available when search quality or maintenance effort
+matters more than self-hosting.
+
+
+## Phase 3: Limited Agent Loop
+
+After the fixed workflows are stable, the backend can add a limited agent loop:
+
+```text
+LLM sees an allowed tool list
+  -> LLM requests a tool call
+  -> backend validates and executes the tool
+  -> tool result is added to context
+  -> LLM continues
+  -> final structured output after at most N steps
+```
+
+Guardrails:
+
+- max tool steps: 3 to 5
+- only read-only tools may run automatically
+- writes go to pending review first
+- all web evidence must be persisted
+- all final outputs must pass schema validation
+- prompts must include explicit evidence boundaries
+
+Permission levels:
+
+```text
+L0: pure analysis, no tools
+L1: read-only tools, web_search / web_fetch / internal_query
+L2: proposal generation, write pending review records
+L3: low-risk notifications and briefs
+L4: database mutation or alert triggering, human confirmation required
+```
+
+
+## Situational Awareness Boundary
+
+Planet's situational-awareness layer should not rely on the LLM as the primary
+risk engine.
+
+Use deterministic analysis for:
+
+- anomaly type
+- affected prefixes
+- affected ASNs
+- geographic scope
+- duration
+- severity score
+- confidence
+- related events
+- raw evidence
+
+Use the LLM for:
+
+- readable summaries
+- risk explanation
+- likely impact narrative
+- next recommended actions
+- missing data requests
+
+In short:
+
+```text
+deterministic services compute the score
+LLM explains the evidence and options
+```
+
+Proactive alerts should be triggered by deterministic rules or scheduled jobs,
+then optionally summarized by the Agent Orchestrator.
+
+
+## Persistence Model
+
+Add lightweight persistence for auditability:
+
+```text
+ai_tasks
+  id
+  task_type
+  status
+  input_json
+  output_json
+  model
+  created_at
+  finished_at
+  error
+
+ai_evidence
+  id
+  task_id
+  source_type
+  title
+  url
+  snippet
+  content_hash
+  retrieved_at
+  credibility_score
+
+ai_briefs
+  id
+  brief_type
+  severity
+  title
+  summary
+  evidence_ids
+  related_entity_ids
+  created_at
+  acknowledged_at
+
+ai_location_suggestions
+  id
+  object_type
+  object_id
+  old_lat
+  old_lon
+  new_lat
+  new_lon
+  confidence
+  reason
+  evidence_ids
+  status
+```
+
+The tables can be introduced incrementally. The first implementation may start
+with `ai_tasks` and `ai_evidence`, then add specialized tables when the UI needs
+review queues and acknowledgement state.
+
+
+## MVP Scope
+
+The MVP should deliver three fixed capabilities:
+
+### 1. Tutorial Refresh
+
+Input:
+
+- provider or tutorial topic
+- current tutorial text
+- known stale point, when available
+
+Tools:
+
+- `web_search`
+- `web_fetch`
+
+Output:
+
+- updated Markdown
+- source list
+- verification status
+
+### 2. Geo Correction
+
+Input:
+
+- object id
+- object name
+- object type
+- current coordinates
+- source description
+
+Tools:
+
+- `web_search`
+- `web_fetch`
+- `geo_resolve`
+
+Output:
+
+- `LocationCorrection` JSON
+- evidence list
+- pending review candidate
+
+### 3. Situation Brief
+
+Input:
+
+- anomaly event
+- deterministic findings
+- internal data summary
+
+Tools:
+
+- `internal_data_query`
+- optional `web_search`
+
+Output:
+
+- `SituationBrief` JSON
+- risk explanation
+- recommended actions
+- missing evidence list
+
+
+## Test Plan
+
+Backend tests:
+
+- WebSearch settings persist to `system_settings` and mask secrets in API responses.
+- Env fallback resolves provider-specific keys before `WEB_SEARCH_API_KEY`.
+- WebSearch provider normalizes success, empty results, 401, 429, and timeout responses.
+- `tutorial_refresh` uses evidence when available and marks output unverified when no evidence exists.
+- `geo_correction` returns pending review candidates and never writes final coordinates directly.
+- `situation_brief` accepts deterministic findings and returns schema-valid summaries.
+- Agent outputs fail closed when schema validation fails.
+
+Frontend tests:
+
+- WebSearch settings card shows configured state, masked key, connection test result, and save feedback.
+- Candidate review UI can display evidence links and pending location suggestions.
+- Situation brief UI can show evidence-backed summaries without exposing raw secrets.
+
+Regression tests:
+
+- existing `aiprovider` status and analysis calls remain unchanged
+- current LLM provider configuration remains the global model source
+- location pipeline tests continue to pass
+- datasource credential guide tests continue to pass
+
+
+## Assumptions
+
+- `aiprovider` remains model-adapter-only.
+- Backend tools are implemented directly in Python first; MCP support is optional and later.
+- Search is evidence collection, not model transport.
+- Writes to important domain tables require human confirmation.
+- Deterministic analysis owns risk scores; LLM output is explanatory and evidence-backed.

+# Custom Source Live Mock 计划
+
+**状态**：实施中  
+**创建日期**：2026-05-01  
+**任务名**：`Custom Source Live Mock`  
+**核心目标**：把自定义源升级为同时支持 REST 与 WebSocket 的可映射采集入口，并提供本地 AIS mock WebSocket 服务，用于验证 Earth 船只实时新增与 upsert 链路。
+
+## 背景
+
+真实 AIS 接口变化频率不可控，无法稳定验证 Earth 页面“不刷新也能看到新船只”的实时链路。当前系统已经有自定义源基础设施：
+
+- `datasource_configs` 保存 endpoint、auth、headers、config。
+- `datasource_mapping_templates` 保存目标 schema 的确定性映射模板。
+- `run-mapped` 支持保存后的自定义 REST 源通过 active mapping 写入目标数据。
+
+但现有能力主要面向 REST sample 和批量 mapping，缺少以下能力：
+
+- 自定义源不能明确选择 `REST` 或 `WebSocket` 采集模式。
+- WebSocket 长连接、订阅消息、重连、消息路径提取还没有通用 runtime。
+- `vessel_ais` 自定义数据写入后需要进入 AIS raw observation 和 `vessels` WS channel，才能真实验证 Earth 实时 upsert。
+- 删除自定义源时没有清晰的数据清理选项。
+- 设置中心里“采集调度 / 凭证 / 自定义源”入口混杂，用户很难判断该在哪里配置。
+
+## 已确认决策
+
+| 项目 | 决策 |
+|-----|------|
+| 计划名称 | `Custom Source Live Mock` |
+| 自定义源传输类型 | 支持 `REST` 与 `WebSocket` |
+| 采集写入方式 | 先映射到目标 schema，再由 destination handler 写入 |
+| AIS mock 目标 | 优先打通 `vessel_ais`，验证 Earth 船只实时新增和同 MMSI upsert |
+| mock 服务 runtime | 使用 `bun` 启动本地 mock WS 服务 |
+| 凭证配置 | 支持 headers、bearer、api key、basic，并保留 query/header API key 位置配置 |
+| 删除策略 | 删除自定义源时允许选择是否删除该源写入的数据 |
+| 合并语义 | 自定义源必须选择“合并到哪个内置数据”，作为内置源的补充数据进入同一聚合链路 |
+| UI 方向 | 自定义源创建和维护放在“配置中心 > 采集器设置”的采集器下拉框内联入口；数据源页保留总览与运行控制 |
+
+## 范围
+
+### 本阶段要做
+
+- 自定义源可选择 `REST` 或 `WebSocket`。
+- 自定义源支持请求头、凭证、query params、body、WS subscribe message。
+- WebSocket 自定义源支持长连接、重连、消息解析、mapping、写入。
+- `vessel_ais` 自定义源写入 AIS raw observations，并广播 `vessels` channel。
+- 提供 mock AIS WS 服务，持续发送新增 MMSI 和位置变更。
+- 删除自定义源时提供“是否删除该源数据”的选项。
+- 梳理设置中心信息架构，明确后续 UI 重构方向。
+
+### 暂不做
+
+- 不新增任意动态数据库表。
+- 不允许用户提交可执行脚本作为 mapping。
+- 不让 LLM 进入正式采集链路。
+- 不把 mock 数据直接写 legacy `vessel_position`，优先写 AIS raw observations，保持可追踪和可删除。
+- 不在本阶段完成完整 `Earth Live Sync`，但要为后续 summary invalidation 留出 hook。

+    J --> K[Earth Vessel Upsert]
+```
+
+## 数据配置设计
+
+短期可以继续复用 `DataSourceConfig`，避免大迁移。语义约定如下：
+
+| 字段 | 用途 |
+|-----|------|
+| `name` | 自定义源唯一名称，例如 `mock_ais_ws` |
+| `source_type` | `rest` 或 `websocket` |
+| `endpoint` | `http(s)://...` 或 `ws(s)://...` |
+| `auth_type` | `none`、`bearer`、`api_key`、`basic` |
+| `auth_config` | token、api_key、key name、basic username/password 等 |
+| `headers` | 静态请求头 |
+| `config` | method、params、body、timeout、retry、WS 订阅消息、重连策略、消息路径等 |
+
+建议 `config` 结构：
+
+```json
+{
+  "transport": "websocket",
+  "delivery_mode": "realtime_stream",
+  "merge_target_source": "barentswatch_vessels",
+  "target_schema": "vessel_ais",
+  "method": "GET",
+  "params": {},
+  "body": null,
+  "timeout": 30,
+  "retry": 3,
+  "ws_subscribe_message": {"type": "subscribe", "channel": "vessels"},
+  "ws_message_path": "$.data",
+  "ws_items_path": "$.vessels[*]",
+  "ws_reconnect": true,
+  "reconnect_delay_seconds": 3,
+  "debug_max_messages": null,
+  "delete_policy": "config_only"
+}
+```
+
+## 后端实施计划
+
+### Phase 1 — 自定义源类型与连接测试
+
+- 允许 `source_type` 为 `rest` 或 `websocket`。
+- REST 连接测试保留现有 HTTP 请求逻辑。
+- WebSocket 连接测试新增：
+  - 校验 endpoint 必须是 `ws://` 或 `wss://`。
+  - 注入 headers 和 auth。
+  - 连接后可选发送 `ws_subscribe_message`。
+  - 读取一条消息或超时返回诊断。
+
+### Phase 2 — Mapped REST Runner 补齐
+
+现有 `run-mapped` 继续作为 REST 一次性采集入口，补齐：
+
+- `GET/POST` method。
+- query params。
+- JSON body。
+- headers 和 auth 注入。
+- sample limit 与响应大小限制。
+- `vessel_ais` destination handler。
+
+### Phase 3 — Mapped WebSocket Runner
+
+新增通用 WebSocket runner，读取 `DataSourceConfig + active mapping`：
+
+- 建立长连接。
+- 发送可选订阅消息。
+- 循环接收消息。
+- JSON parse。
+- 按 `ws_message_path/ws_items_path` 提取 item 或 list。
+- 使用 mapping engine 转换。
+- 使用 target schema validator 校验。
+- 调用 destination handler 写入。
+- 更新采集任务状态：
+  - `connecting`
+  - `streaming`
+  - `reconnecting`
+  - `stopped`
+- 维护运行指标：
+  - `messages_seen`
+  - `records_written`
+  - `unique_entities`
+  - `last_message_at`
+  - `last_error`
+- 后台长连接不读取 `config.debug_max_messages`；该字段只用于显式的一次性调试运行，避免正式 WS 流被测试上限截断。
+
+### Phase 4 — Destination Handler
+
+为 target schema 建立明确写入处理器。
+
+`vessel_ais` handler：
+
+- 写入 `AISRawObservation`。
+- `source = datasource.name`。
+- `delivery_mode` 来自 config，默认 WS 为 `realtime_stream`、REST 为 `polling`。
+- `transport` 来自 `source_type`。
+- 生成幂等 observation hash。
+- 更新 AIS source health。
+- 广播 `vessels` channel，payload 使用当前 Earth 已支持的 upsert 格式。
+
+`generic_records` handler：
+
+- 写入通用 collected data 或后续 generic store。
+- 不直接进入 Earth。
+
+### Phase 5 — 删除与数据清理
+
+删除自定义源时新增清理策略：
+
+| 选项 | 行为 |
+|-----|------|
+| 只删除配置 | 删除 `datasource_configs`，保留 mapping 和历史数据需要另行处理 |
+| 删除配置和 mapping | 删除配置及对应 `datasource_mapping_templates` |
+| 删除配置、mapping 和该源数据 | 同时删除该源写入的数据 |
+
+数据删除范围：
+
+- `collected_data.source == datasource.name`
+- `ais_raw_observations.source == datasource.name`
+- `ais_source_health.source == datasource.name`
+
+不建议直接删除 legacy `vessel_position`，因为当前 legacy 表不带 source，无法安全归因。自定义 AIS 源应优先只写 raw observations。
+
+删除数据后应触发：
+
+- `vessels` channel 的 reload/invalidation 事件，提示 Earth 重新拉船只聚合。
+- 后续接入 `Earth Live Sync` 后，触发 `earth_summary` invalidation。
+
+### Phase 6 — Mock AIS WebSocket 服务
+
+新增脚本：
+
+`scripts/mock-ais-ws-server.ts`
+
+运行方式建议：
+
+```bash
+bun run mock:ais-ws
+```
+
+服务行为：
+
+- 监听 `ws://localhost:8787/ais`。
+- 接受任意客户端连接。
+- 可记录收到的 subscribe message。
+- 每 1-2 秒发送一条 AIS-like JSON。
+- 每隔 N 条生成新 MMSI，验证船只数量增长。
+- 已存在 MMSI 随时间改变 `lat/lon/cog/heading`，验证同 MMSI upsert。
+- 支持固定 seed，保证测试可复现。
+
+示例 payload：
+
+```json
+{
+  "type": "vessel",
+  "data": {
+    "mmsi": "999000001",
+    "name": "MOCK VESSEL 001",
+    "lat": 31.23,
+    "lon": 121.47,
+    "sog": 12.4,
+    "cog": 86,
+    "heading": 90,
+    "received_at": "2026-05-01T00:00:00Z"
+  }
+}
+```
+
+## 前端实施计划
+
+### 信息架构调整
+
+自定义源不作为割裂的新入口，而是作为内置采集器的补充源，直接纳入“配置中心 > 采集器设置”的采集器选择器：
+
+- 采集器下拉框同时展示内置采集器和自定义补充源。
+- 下拉框右侧提供加号按钮，用于添加自定义源。
+- 新建自定义源时必须选择“合并到内置数据”，例如合并到 `barentswatch_vessels`。
+- 选择自定义源后，右侧基础配置区域沿用正常采集器配置形态，支持连接测试、保存、endpoint、headers、auth、高级 JSON。
+- 自定义源比内置源多一个“删除自定义源”按钮。
+- 删除时弹出确认框，可勾选“同时删除该自定义源生成的所有数据”。
+
+数据源页保留：
+
+- 内置源总览。
+- 内置源最近状态。
+- 内置源手动触发。
+- 不展示自定义源管理入口；自定义源创建、维护、删除统一在采集器设置中完成。
+
+### 自定义源表单
+
+新增或重构自定义源表单：
+
+- 源名称。
+- 类型：`REST` / `WebSocket`。
+- 合并到内置数据：必选，用于声明该源补充哪个内置数据域。
+- endpoint。
+- method/body/params，仅 REST 显示。
+- subscribe message/message path/items path，仅 WS 显示。
+- auth type。
+- headers。
+- target schema。
+- sample/test 按钮。
+- mapping assistant/preview。
+- 保存并运行。
+
+### 删除确认
+
+删除自定义源时弹出确认：
+
+- 默认只删除配置。
+- 可勾选删除 mapping。
+- 可勾选删除该源写入的数据。
+- 显示将删除的数据范围和不可恢复提示。
+
+## 验证方案
+
+### Mock WS 验证路径
+
+1. 启动 mock 服务：
+
+```bash
+bun run mock:ais-ws
+```
+
+2. 新建自定义源：
+
+| 字段 | 值 |
+|-----|----|
+| name | `mock_ais_ws` |
+| source_type | `websocket` |
+| endpoint | `ws://localhost:8787/ais` |
+| merge_target_source | `barentswatch_vessels` |
+| target_schema | `vessel_ais` |
+| ws_message_path | `$.data` |
+
+3. 保存 active mapping：
+
+```json
+{
+  "source": {
+    "items_path": "$"
+  },
+  "fields": {
+    "mmsi": {"path": "$.mmsi", "type": "integer"},
+    "name": {"path": "$.name", "type": "string"},
+    "lat": {"path": "$.lat", "type": "float"},
+    "lon": {"path": "$.lon", "type": "float"},
+    "sog": {"path": "$.sog", "type": "float", "default": null},
+    "cog": {"path": "$.cog", "type": "float", "default": null},
+    "heading": {"path": "$.heading", "type": "integer", "default": null},
+    "received_at": {"path": "$.received_at", "type": "datetime", "default": null}
+  }
+}
+```
+
+4. 启动自定义源。
+
+5. 打开 Earth 船只图层，不刷新页面观察：
+
+- `vessels` WS channel 收到 `source = mock_ais_ws`。
+- HUD 船只数在新 MMSI 到达时增加。
+- 地球出现 `MOCK VESSEL`。
+- 同 MMSI 后续消息更新位置和航向，不重复叠加。
+
+### 自动化测试
+
+后端测试：
+
+- WebSocket 自定义源连接测试。
+- WS message path 和 items path 提取。
+- mapping 到 `vessel_ais`。
+- 写入 AIS raw observation。
+- 广播 `vessels` channel。
+- 删除自定义源时按策略删除 mapping 和源数据。
+
+前端测试：
+
+- REST/WS 表单条件显示。
+- 删除确认选项。
+- mock 源配置保存 payload。
+- mapping preview 展示错误和成功记录。
+
+## 风险与约束
+
+- WebSocket 自定义源是长连接，不能沿用一次性 REST 进度条。
+- 如果 mock 源写 legacy vessel 表，删除会变得不安全，因此先只写 raw observations。
+- 自定义 WS 可能消息量很大，必须有 backpressure、日志限流和任务取消能力。
+- 任意外部 WS 不能信任 payload，必须经过 mapping 和 schema validation。
+- headers/auth 不能进入 LLM mapping prompt。
+
+## 交付顺序
+
+1. Mock AIS WS 服务。
+2. 后端自定义 WS runner。
+3. `vessel_ais` destination handler 和 `vessels` broadcast。
+4. 删除自定义源及数据清理。
+5. 设置中心采集器下拉框内联自定义源 UI。
+6. 配置中心信息架构重整。
+7. 与 `Earth Live Sync` 对接 summary invalidation。
