+# Agent Handoff Notes
+
+This project is a React 18 + FastAPI macroeconomic causal analysis app. The current active product surface is CausalFlow v2.
+
+## Project Structure
+
+Backend:
+
+- v2 router: `backend/app/api/v2_router.py` mounted at `/api/v2`.
+- v1 router: `backend/app/api/causal_router.py` mounted at `/api/v1`, legacy.
+- v2 service: `backend/app/services/v2_analysis_service.py`.
+- API version guide: `backend/API_VERSIONS.md` explains v1 vs v2.
+
+Frontend:
+
+- Main app: `frontend/src/App.jsx`.
+- Production components: `frontend/src/components/`.
+- Demo files, when present, belong under `frontend/src/demo/`.
+
+Documentation:
+
+- v2 docs: `docs/v2-architecture.md`, `docs/v2-api-guide.md`, `docs/v2-runbook.md`.
+- Roadmaps: `CAUSAL_FLOW_ROADMAP.md` and `PROJECT_ROADMAP.md`.
+- Cleanup report: `CLEANUP_REPORT.md` records the 2026-05-06 cleanup when present.
+
+## Current v2 Entry Points
+
+- Backend router: `backend/app/api/v2_router.py`, mounted at `/api/v2` from `backend/main.py`.
+- v2 orchestration/session service: `backend/app/services/v2_analysis_service.py`.
+- Frontend workspace: `frontend/src/App.jsx`.
+- Multi-input form: `frontend/src/components/QueryPanel.jsx`.
+- Graph presentation: `frontend/src/components/CausalGraph.jsx` and `frontend/src/components/CustomNode.jsx`.
+
+## Run Commands
+
+Backend:
+
+```powershell
+cd backend
+python -m uvicorn main:app --host 127.0.0.1 --port 8000
+```
+
+Frontend:
+
+```powershell
+cd frontend
+npm.cmd run dev -- --host 0.0.0.0 --port 5173
+```
+
+Build verification:
+
+```powershell
+cd frontend
+npm.cmd run build
+```
+
+In the Codex sandbox, Vite/esbuild may require elevated execution because it starts a child process.
+
+## Important Constraints
+
+- Do not reintroduce hard-coded API keys in docs or code. Use `backend/.env` with `OPENAI_API_KEY`.
+- The repository was cleaned on 2026-05-06: temporary/debug files were removed, obsolete components were deleted, and demo files were organized to `frontend/src/demo/`. Keep edits scoped to production files.
+- v2 is designed to run without an LLM key by using deterministic macro fallback graphs. Search and LLM enrichment improve quality when keys are present.
+- Generated runtime DB files under `backend/data/` are local state and should not be committed.
+- SearchService duplication in `two_pass_causal_service.py` was fixed; shared search behavior should live in `search_service.py`.
+- v1 is legacy/stateless and v2 is recommended/session-based. See `backend/API_VERSIONS.md` when available.
+
+## Cross-Platform Shared Knowledge
+
+
+
+### Project Facts
+
+- Product priority is CausalFlow v2: a session-based macroeconomic causal analysis workspace for multi-input synthesis, iterative deep expansion, node expansion, and real-time node enrichment.
+- Recommended API surface is `/api/v2`; `/api/v1` remains legacy and stateless.
+- v2 session state is persisted through SQLite by `backend/app/services/v2_analysis_service.py`; generated files under `backend/data/` are runtime state and should not be committed.
+- The graph presentation was redesigned on 2026-05-07 to use layered lanes, cluster filters, and edge modes (`main`, `focus`, `all`) so dense macro graphs remain readable.
+- The left input sidebar was fixed on 2026-05-07 with `min-h-0` and internal scrolling so many clues can be entered.
+
+### Conventions
+
+- Keep real API keys out of repository docs and code. Use `backend/.env` and placeholders in committed files.
+- Prefer v2 docs for new work: `docs/v2-architecture.md`, `docs/v2-api-guide.md`, and `docs/v2-runbook.md`.
+- Keep temporary smoke-test SQLite data out of git.
+
+### References
+
+- Claude memory path inspected for this project: `C:\Users\28203\.claude\projects\X--vibe-coding-6-----\memory`.
+- Existing Claude project memories cover product vision, search pipeline fixes, and the 2026-05-06 cleanup.

+*修复*.md
+*优化*.md
+*问题*.md
+*总结*.md
+DEBUG_*.md
+URGENT_*.md
+
+# 临时脚本
+test_*.bat
+upload_*.bat
+upload_*.ps1
+```
+
+### 4. 文档维护建议
+
+- 定期检查是否有新的临时文档累积
+- 修复完成后及时删除调试文档
+- 使用 git commit message 记录修复内容,而不是创建单独的修复文档
+

-# 因果引擎 Debug 报告
-
-## 问题诊断
-
-用户反馈:前端一直显示"运行中"状态,转圈无结果。
-
-## 根本原因
-
-通过审查代码和日志,发现了以下关键问题:
-
-### 1. **CORS 配置错误** ⚠️ 最严重
-**位置**: `backend/main.py`
-
-**问题**:
-```python
-allow_origins=["http://localhost:5173"] # 只允许 5173 端口
-```
-
-**实际情况**: 前端运行在 5174 端口(因为 5173 被占用)
-
-**影响**: 浏览器阻止所有跨域请求,导致前端无法与后端通信
-
-**修复**:
-```python
-allow_origins=["http://localhost:5173", "http://localhost:5174"] # 支持两个端口
-```
-
----
-
-### 2. **域名白名单加载失败** 🔧
-**位置**: `backend/app/services/multi_tool_router_service.py`
-
-**问题**:
-```python
-def _get_all_search_domains(self) -> List[str]:
- domains = []
- for category in self.config["search_domains"].values():
- if isinstance(category, list): # ❌ 错误:配置是嵌套字典,不是列表
- domains.extend(category)
- return domains
-```
-
-**结果**: 白名单域名数量为 0,导致所有搜索都失败
-
-**修复**:
-```python
-def _get_all_search_domains(self) -> List[str]:
- domains = []
- for category_name, category_data in self.config["search_domains"].items():
- if category_name == "description":
- continue
- if isinstance(category_data, dict) and "domains" in category_data:
- domains.extend(category_data["domains"])
- return domains
-```
-
-**验证**: 日志显示从 `0 个` 增加到 `22 个` ✅
-
----
-
-### 3. **默认路由规则缺失字段** 🔧
-**位置**: `backend/app/services/multi_tool_router_service.py`
-
-**问题**: 当节点类型没有匹配规则时,默认规则缺少 `tier_1_domains` 和 `tier_2_domains` 字段
-
-**影响**: 瀑布流搜索逻辑无法获取白名单,导致搜索失败
-
-**修复**:
-```python
-# 默认规则:使用新闻搜索
-all_domains = self._get_all_search_domains()
-
-return {
- "primary_strategy": "news_search",
- "fallback_strategy": None,
- "preferred_apis": [],
- "tier_1_domains": all_domains[:10] if len(all_domains) > 10 else all_domains,
- "tier_2_domains": all_domains[10:] if len(all_domains) > 10 else []
-}
-```
-
----
-
-## 修复验证
-
-### 后端日志对比
-
-**修复前**:
-```
-2026-02-19 19:32:38 [INFO] - 搜索域名白名单: 0 个
-```
-
-**修复后**:
-```
-2026-02-19 21:15:04 [INFO] - 搜索域名白名单: 22 个
-```
-
-### 系统状态
-
-✅ 后端运行正常 (PID: 20840, 端口: 8000)
-✅ 前端运行正常 (端口: 5174)
-✅ CORS 配置已修复
-✅ 域名白名单加载成功
-✅ 健康检查通过: `{"status":"healthy"}`
-
----
-
-## 下一步操作
-
-### 1. 刷新浏览器页面
-按 `Ctrl + Shift + R` 强制刷新,清除缓存
-
-### 2. 测试分析功能
-在前端输入查询(如"黄金价格"),点击"开始分析"
-
-### 3. 检查浏览器控制台
-按 `F12` 打开开发者工具,查看是否还有错误
-
-### 4. 查看后端日志
-观察终端输出,确认请求正常处理
-
----
-
-## 预期行为
-
-修复后,系统应该:

-- **LLM**: DeepSeek API (deepseek-reasoner 模型)
-- **数据源**: Mock 模式(未配置真实搜索 API)
-
-### 双阶段分析流程
-1. **Pass 1**: LLM 生成因果图谱结构
-2. **Pass 2**: 多路由数据获取
- - 路由 1: Yahoo Finance 直连(资产价格)
- - 路由 2: 结构化 API(宏观指标,Mock 模式)
- - 路由 3: 新闻搜索(事件/情绪,Mock 模式)
-
----
-
-## 已修复文件清单
-
-1. `backend/main.py` - CORS 配置
-2. `backend/app/services/multi_tool_router_service.py` - 域名白名单加载 + 默认路由规则
-
----
-
-## 注意事项
-
-⚠️ **Mock 模式**: 当前系统运行在 Mock 模式,搜索引擎返回模拟数据。如需真实数据,请配置:
-- `TAVILY_API_KEY` 或 `SERPER_API_KEY` (搜索引擎)
-- `FRED_API_KEY` (美联储经济数据)
-- `TUSHARE_TOKEN` (中国金融数据)
-
-⚠️ **端口冲突**: 如果 5173 端口被释放,前端可能切换回 5173,届时需要重启前端服务。

+# 因果推演引擎 v2.0 — 项目规划
+
+> **文档范围:** 本文档描述整体项目愿景、产品规划和长期发展方向。
+>
+> **相关文档:** 如需了解 v2 版本的技术架构和实现细节,请参考 `CAUSAL_FLOW_ROADMAP.md`
+
+**最后更新**: 2026-05-05
+**当前阶段**: Phase 1 骨架已落地,进入数据与可视化打磨
+**优先级**: 多输入综合分析 > 深度迭代分析 > 真实数据管道 > 高级可视化
+
+---
+
+## 项目愿景
+
+从**浅层单输入分析工具**升级为**深度多维宏观经济因果分析平台**。
+
+用户场景:宏观经济研究者需要分析黄金价格,涉及美联储利率、美元信用、全球资金流向、日元套息交易、地缘政治等数十个相互关联的因素。当前工具无法:
+- 从多个看似不相关的输入中发现隐藏关联
+- 自动发现并补全影响因素
+- 输出复杂的多维因果图谱
+- 获取最新实时数据
+
+---
+
+## 核心问题诊断
+
+| 问题 | 根因 | 影响 |
+|------|------|------|
+| 分析太浅 | 单次 LLM 调用生成全部拓扑,max 3 层 7 节点,无迭代深化 | 无法探索复杂因果链 |
+| 不能多输入分析 | 所有 API 只接受单个 query/target 字符串 | 无法综合多个信息源 |
+| 不能自动发现关联因素 | 无图扩展机制,生成后图谱静态不变 | 用户无法交互式探索 |
+| 搜不到最新数据 | 结构化 API 100% mock;搜索 5s 超时无重试;白名单过滤丢弃 80%+ 结果 | 节点数据过时/缺失 |
+| 图谱太简单 | 固定 5 种节点类型,仅 dagre 布局,无层级/聚类/子图 | 50+ 节点图谱无法导航 |
+
+---
+
+## 实施分期
+
+### Phase 1: 多输入综合分析 + 深度扩展(3-4 周)⭐ 最高优先级
+
+**目标**: 输入 N 条不相关信息 → AI 找出隐藏关联 → 发现共同影响目标 → 自动补全其他因素
+
+**后端任务**:
+- [x] 修复搜索管道: 超时 5s→15s、指数退避重试(3次)、质量评分替代白名单
+- [x] 构建 v2 深度扩展骨架(`V2AnalysisService.analyze_deep_stream`,支持 SSE 分层增量)
+- [x] 构建 v2 多输入综合骨架(`V2AnalysisService.synthesize_stream`,支持子图 → 桥接 → 共同目标 → 数据填充)
+- [ ] 构建 `AutoDiscoveryEngine`(三源发现:LLM + 搜索 + 相关性)
+- [x] 会话管理(Session CRUD + 图谱状态持久化,SQLite 默认写入 `backend/data/causal_v2.sqlite3`)
+- [x] SSE 流式推送(每个阶段实时反馈进度)
+- [ ] 语义去重服务(LLM 判断节点是否为同一概念)
+
+**前端任务**:
+- [x] 多输入面板(支持添加/删除多条输入,标记类型:事件/数据/新闻/问题)
+- [x] 渐进式图谱渲染(接收 SSE 过程图谱,阶段性更新画布)
+- [x] 节点扩展交互(点击节点 → 原因 / 影响 / 相关)
+- [x] 大图可读性改造(分层泳道、聚类筛选、主干/聚焦/全部边模式)
+
+**交付物**: 输入"美联储暂停加息"+"日元套息交易平仓"+"中国房地产危机" → 看到三者如何关联 → 发现共同影响黄金/美债 → 自动补全其他影响因素。
+
+**关键文件**:
+- `backend/app/services/v2_analysis_service.py` (新建:v2 会话、多输入综合、深度扩展、节点扩展)
+- `backend/app/services/auto_discovery_engine.py` (新建)
+- `backend/app/api/v2_router.py` (新建)
+- `backend/app/services/node_sensing_service.py` (修改:搜索管道)
+- `frontend/src/components/QueryPanel.jsx` (修改:多输入 + 深度模式)
+- `frontend/src/App.jsx` (修改:多输入 + 会话管理 + SSE 事件流)
+- `frontend/src/components/CausalGraph.jsx` (修改:分层泳道 + 边模式 + 聚类筛选)
+
+---
+
+### Phase 2: 真实数据管道 + 数据时效性(2-3 周)
+
+**目标**: 每个节点都有最新真实数据,不再是 mock
+
+**任务**:
+- [ ] 接入 yfinance(股票/外汇/商品实时价格,无需 key)
+- [ ] 接入 FRED API(美国宏观指标:利率/CPI/GDP/就业)
+- [ ] 接入 Alpha Vantage(外汇/加密货币)
+- [ ] 来源质量评分系统(替代二元白名单)
+- [ ] Redis/内存缓存层(搜索 15min TTL,价格 5min TTL)
+- [ ] 后台定时刷新(关键指标每小时更新)
+- [ ] DuckDuckGo 免费兜底搜索
+
+**交付物**: 图谱中每个节点显示真实最新数据(如"联邦基金利率: 5.25-5.50%, 2026-05-05 更新")。
+
+---
+
+### Phase 3: 高级可视化(2-3 周)
+
+**目标**: 50-200 节点的复杂图谱依然清晰可读
+
+**任务**:
+- [ ] 层级聚类布局(按领域分组:货币政策/地缘/市场/结构性,可折叠)
+- [ ] Force-directed 布局(大图聚类发现)
+- [ ] 径向布局(目标资产居中,影响因素按层级向外辐射)
+- [ ] 过滤面板(按类型/置信度/领域/时间筛选)
+- [ ] 大图性能优化(虚拟渲染 + LOD)
+- [ ] 图谱导出(SVG/PNG)
+
+**交付物**: 50+ 节点的宏观分析图谱,按领域聚类,可折叠展开,交互流畅。
+
+---
+
+### Phase 4: 打磨与持久化(1-2 周)
+
+**目标**: 生产级体验
+
+**任务**:
+- [ ] SQLite 持久化会话(关闭浏览器后可恢复)
+- [ ] 撤销/重做
+- [ ] 分析历史列表
+- [ ] 键盘快捷键
+- [ ] 错误处理与边界情况
+
+---
+
+## 技术决策
+
+| 决策 | 选择 | 理由 |
+|------|------|------|
+| LLM 提供商 | 保持 DeepSeek | 已集成,成本低,支持迭代调用 |
+| 图数据库 | SQLite 优先,Neo4j 后续 | MVP 无外部依赖;Neo4j 用于复杂查询 |
+| 缓存 | Redis(生产)/ 内存 dict(开发) | 标准、快速、TTL 支持 |
+| 前端状态 | Zustand | 轻量,适合频繁变化的图状态 |
+| 搜索引擎 | Tavily + Serper + DuckDuckGo | 多源冗余,降级策略 |
+| 流式推送 | SSE(现有)→ WebSocket(Phase 5) | SSE 足够单向推送;WebSocket 用于协作编辑 |
+
+---
+
+## 风险与应对
+
+| 风险 | 应对 |
+|------|------|
+| LLM 调用成本爆炸(迭代式) | 限制 max_nodes=50;缓存 LLM 响应;去重减少调用 |
+| 深层分析幻觉 | 每层用搜索结果验证;置信度随层级衰减 |
+| 搜索 API 限流 | 指数退避 + 多供应商 + 积极缓存 |
+| 前端 200+ 节点卡顿 | 虚拟渲染 + LOD + 聚类折叠 |
+| 循环推理 | 每次扩展带入完整图谱上下文 + 明确"不要重复"指令 |
+
+---
+
+## 验证方式
+
+1. **深度分析**: 输入"黄金价格" → 验证生成 20+ 节点、5+ 层深度、每层 SSE 推送
+2. **多输入综合**: 输入 3 条不相关新闻 → 验证找到交叉关联和共同目标
+3. **节点扩展**: 点击任意节点 → 验证新增 2-4 个相关节点
+4. **数据时效**: 检查节点数据时间戳 → 验证为当天/近期真实数据
+5. **大图性能**: 生成 50+ 节点图谱 → 验证交互流畅无卡顿
+6. **端到端**: 启动 backend + frontend → 完整走通上述场景

-# 快速测试指南
-
-## 立即测试修复结果
-
-### 方法 1: 浏览器测试(推荐)
-
-1. **打开浏览器**
- 访问: http://localhost:5174
-
-2. **强制刷新页面**
- 按 `Ctrl + Shift + R` (Windows) 或 `Cmd + Shift + R` (Mac)
-
-3. **输入测试查询**
- 在"分析问题"框中输入: `黄金价格`
-
-4. **点击"开始分析"**
- 等待 20-30 秒,应该看到因果关系图谱
-
-5. **检查结果**
- - 应该显示多个节点(美元指数、美联储利率、通货膨胀等)
- - 每个节点应该有实时数据(如果有的话)
- - 底部应该显示数据源面板
-
----
-
-### 方法 2: API 直接测试
-
-打开新的 PowerShell 窗口,运行:
-
-```powershell
-# 测试健康检查
-Invoke-RestMethod -Uri "http://localhost:8000/health"
-
-# 测试因果分析(需要等待 30-60 秒)
-$body = @{
- query = "黄金价格"
- context = $null
- max_depth = 3
-} | ConvertTo-Json
-
-Invoke-RestMethod -Uri "http://localhost:8000/api/v1/analyze-v2" `
- -Method POST `
- -Body $body `
- -ContentType "application/json" `
- -TimeoutSec 60
-```
-
----
-
-## 预期结果
-
-### 成功的标志
-
-✅ 前端不再一直转圈
-✅ 20-30秒后显示因果图谱
-✅ 节点包含实时数据(部分节点可能显示 "unknown",这是正常的 Mock 模式行为)
-✅ 浏览器控制台没有 CORS 错误
-
-### 正常的 Mock 模式行为
-
-由于系统运行在 Mock 模式(未配置真实 API),部分节点可能显示:
-- `latest_value: "unknown"` - 这是正常的
-- `latest_value: "稳定趋势"` - 这是 LLM 从模拟数据中提取的
-- `latest_value: "103.5"` - 这是从模拟新闻中提取的数值
-
----
-
-## 如果还有问题
-
-### 1. 检查浏览器控制台
-按 `F12` 打开开发者工具,查看 Console 标签页:
-- ❌ 如果看到 CORS 错误 → 后端可能没有重启,等待几秒
-- ❌ 如果看到 Network Error → 检查后端是否运行在 8000 端口
-
-### 2. 检查后端日志
-查看运行后端的终端窗口:
-- ✅ 应该看到: `搜索域名白名单: 22 个`
-- ✅ 应该看到: `Application startup complete`
-- ❌ 如果看到错误 → 查看 DEBUG_REPORT.md
-
-### 3. 重启服务(如果需要)
-
-**重启后端**:
-```powershell
-# 在后端终端按 Ctrl+C 停止
-# 然后重新运行
-cd X:\因果引擎\backend
-python main.py
-```
-
-**重启前端**:
-```powershell
-# 在前端终端按 Ctrl+C 停止
-# 然后重新运行
-cd X:\因果引擎\frontend

+- 多输入综合分析:左侧面板可输入多条事件/数据/新闻/问题,后端通过 `/api/v2/sessions/{session_id}/synthesize` 以 SSE 推送阶段进度。
+- 深度迭代扩展:后端通过 `/api/v2/sessions/{session_id}/analyze-deep` 按层生成增量图谱。
+- 会话管理:v2 会话使用 SQLite 持久化,默认运行态路径为 `backend/data/causal_v2.sqlite3`。
+- 节点扩展:点击图谱节点后,可通过 `/api/v2/sessions/{session_id}/expand` 扩展原因、影响或相关因素。
+- 图谱呈现:前端使用分层泳道布局、聚类筛选、主干/聚焦/全部边模式,避免大图节点重叠和连线过密。
+- 数据管道:搜索感知支持 15 秒超时、3 次指数退避、15 分钟缓存和来源质量评分;结构化数据服务新增 yfinance 入口。
+
+**API 版本说明:**
+- **v2 API** (推荐): 会话式设计,支持多轮交互、撤销/重做、多输入综合分析。详见 `backend/API_VERSIONS.md`
+- **v1 API** (维护模式): 无状态设计,适合简单的一次性分析。

-# Yahoo Finance 429 错误解决方案
-
-## 问题诊断
-
-### 症状
-所有节点数据显示 `unknown`,Yahoo Finance 无法获取数据。
-
-### 根本原因
-从日志发现:
-```
-2026-02-19 21:21:25 [ERROR] yfinance: 429 Client Error: Too Many Requests
-2026-02-19 21:21:28 [ERROR] [YahooFinance] 获取失败: DX-Y.NYB - Expecting value: line 1 column 1
-```
-
-**Yahoo Finance API 触发了速率限制(Rate Limiting)**
-
-原因:
-1. 短时间内发送了大量并发请求
-2. 每次分析"黄金价格"会同时请求 6-7 个节点(美元指数、黄金价格、黄金供应、黄金需求等)
-3. 多次测试导致请求累积,触发 Yahoo 的反爬虫机制
-
----
-
-## 已实施的解决方案
-
-### 1. 添加重试机制 + 指数退避
-
-修改了 `yahoo_finance_service.py` 的 `fetch_financial_data` 方法:
-
-**新增功能**:
-- ✅ 最多重试 3 次
-- ✅ 指数退避延迟:2秒 → 4秒 → 8秒
-- ✅ 自动检测 429 错误并重试
-- ✅ 详细的日志记录
-
-**代码逻辑**:
-```python
-for attempt in range(max_retries):
- try:
- if attempt > 0:
- delay = 2 ** attempt # 2s, 4s, 8s
- await asyncio.sleep(delay)
-
- # 调用 yfinance
- stock = yf.Ticker(ticker)
- info = stock.info
-
- # 获取数据...
- return result
-
- except Exception as e:
- if "429" in str(e):
- # 速率限制,继续重试
- continue
- else:
- # 其他错误,也重试
- continue
-```
-
----
-
-## 使用建议
-
-### 1. 等待速率限制解除
-
-**当前状态**:你的 IP 已被 Yahoo Finance 临时封禁
-
-**建议等待时间**:
-- 最少等待:**15-30 分钟**
-- 保险等待:**1-2 小时**
-
-### 2. 测试时减少请求频率
-
-**避免**:
-- ❌ 连续多次测试同一个查询
-- ❌ 短时间内测试多个不同查询
-- ❌ 刷新页面重复请求
-
-**推荐**:
-- ✅ 每次测试后等待 30 秒
-- ✅ 使用不同的查询词(避免重复节点)
-- ✅ 先测试单个简单查询
-
-### 3. 测试步骤
-
-**30分钟后,按以下步骤测试**:
-
-1. **刷新浏览器**(Ctrl + Shift + R)
-
-2. **输入简单查询**:`比特币`
- - 这个查询只会生成 2-3 个节点
- - 减少并发请求数量
-
-3. **观察日志**:
- ```
- [YahooFinance] ✓ 成功: BTC-USD = 50000.00 USD (rising, +2.5%)
- ```
-
-4. **如果仍然 429**:
- - 继续等待 30 分钟
- - 或者切换网络(使用手机热点)
-
----
-
-## 长期优化建议
-
-### 方案 1: 添加请求间隔(推荐)
-
-在并发请求之间添加延迟:
-
-```python
-# 在 two_pass_causal_service.py 的 _pass2_enrich_with_provenance 中
-async def _pass2_enrich_with_provenance(self, topology):
- nodes = topology["nodes"]
- enriched_nodes = []
-
- for node in nodes:
- result = await self._enrich_single_node(node)
- enriched_nodes.append(result)
-
- # 添加延迟避免速率限制
- await asyncio.sleep(0.5) # 每个节点间隔 0.5 秒
-
- return {"nodes": enriched_nodes, ...}
-```
-
-### 方案 2: 使用缓存
-
-缓存 Yahoo Finance 数据,避免重复请求:
-
-```python
-from functools import lru_cache
-from datetime import datetime, timedelta
-
-class YahooFinanceService:
- def __init__(self):
- self.cache = {} # {ticker: (data, timestamp)}
- self.cache_ttl = 300 # 5分钟缓存
-
- async def fetch_financial_data(self, ticker, ...):
- # 检查缓存
- if ticker in self.cache:
- data, timestamp = self.cache[ticker]
- if (datetime.now() - timestamp).seconds < self.cache_ttl:
- logger.info(f"[YahooFinance] 使用缓存: {ticker}")
- return data
-
- # 获取新数据
- result = await self._fetch_from_api(ticker)
-
- # 更新缓存
- self.cache[ticker] = (result, datetime.now())
- return result
-```
-
-### 方案 3: 使用代理池
-
-如果需要高频请求,考虑使用代理服务:
-- 轮换 IP 地址
-- 分散请求压力
-- 避免单个 IP 被封禁
-
----
-
-## 当前系统状态
-
-✅ **已修复**:
-- 重试机制已添加
-- 指数退避已实现
-- 429 错误检测已启用
-
-⏳ **等待中**:
-- Yahoo Finance 速率限制解除(15-30分钟)
-
-🔄 **下次测试**:
-- 等待 30 分钟后
-- 使用简单查询(如"比特币")
-- 观察是否成功获取数据
-
----
-
-## 故障排查
-
-### 如果 30 分钟后仍然失败
-
-**检查 1:确认后端已重启**
-```bash
-# 查看日志,应该看到:
-[YahooFinance] 初始化完成,支持 49 个资产映射
-```
-
-**检查 2:测试 yfinance 是否可用**
-```python
-import yfinance as yf
-ticker = yf.Ticker("BTC-USD")
-print(ticker.info.get("regularMarketPrice"))
-```
-
-**检查 3:切换网络**
-- 使用手机热点
-- 或者使用 VPN
-
-**检查 4:降级到 Mock 模式**
-如果 Yahoo Finance 持续不可用,系统会自动降级到新闻搜索模式。
-
----
-
-## 总结
-
-**问题**:Yahoo Finance 429 速率限制
-**原因**:短时间内发送了过多请求
-**解决**:添加重试机制 + 指数退避
-**状态**:等待速率限制解除(15-30分钟)
-**测试**:30分钟后使用"比特币"查询测试

-# Yahoo Finance 直连旁路架构 (Direct API Bypass)
-
-## 📋 问题背景
-
-在使用 Search API 获取金融数值时遇到严重问题:
-- ❌ **付费墙拦截**:Bloomberg、Reuters 等顶级媒体需要订阅
-- ❌ **数据稀缺**:7天时间窗内缺乏实时价格数据
-- ❌ **高频 unknown**:大量价格类节点无法获取有效数据
-
-## 🎯 解决方案
-
-为"资产价格/宏观指标"类节点构建 **Yahoo Finance 直连旁路**,绕过付费墙,直接获取高精度实时数据。

+
+# v2: 先创建会话
+session = requests.post("/api/v2/sessions", json={
+ "title": "我的分析",
+ "description": "..."
+}).json()
+session_id = session["id"]
+```
+
+**2. 执行分析**
+```python
+# v1: 一次性分析
+response = requests.post("/api/v1/analyze", json={"query": "..."})
+
+# v2: 会话式分析(支持流式)
+response = requests.post(
+ f"/api/v2/sessions/{session_id}/analyze-deep",

+# QVeris 数据源接入文档
+
+## 概述
+
+QVeris 是一个真实世界数据源,已成功集成到 CausalFlow 因果推演引擎中。本文档说明如何使用 QVeris 客户端。
+
+## 架构设计
+
+```
+backend/
+├── infrastructure/ # 基础设施层(新增)
+│ └── data_sources/ # 数据源模块
+│ ├── __init__.py
+│ └── qveris_client.py # QVeris 客户端实现
+├── .env # 环境变量配置(包含 API Key)
+├── .env.example # 环境变量示例
+└── test_qveris.py # QVeris 测试脚本
+```
+
+## 环境配置
+
+### 1. 环境变量
+
+在 `backend/.env` 文件中已配置:
+
+```env
+# QVeris 真实世界数据源 API
+QVERIS_API_KEY=sk-NQ-pJnadi4ow0f9mQIh6JML9YFspoS5HCa2j55AO8K4
+```
+
+### 2. API 端点配置
+
+默认 API 端点:`https://api.qveris.com/v1`
+
+如需自定义,可在 `.env` 中添加:
+
+```env
+QVERIS_BASE_URL=https://your-custom-endpoint.com/v1
+```
+
+## 使用方法
+
+### 基础用法
+
+```python
+from infrastructure.data_sources import QVerisClient
+
+# 创建客户端实例
+client = QVerisClient()
+
+# 发送查询请求
+result = client.query_agent("查询最新的铜价数据")
+
+# 处理响应
+if result['status'] == 'success':
+ print(f"数据源: {result['source']}")
+ print(f"原始数据: {result['raw_data']}")
+ print(f"解析数据: {result['parsed_data']}")
+else:
+ print(f"查询失败: {result['error_message']}")
+```
+
+### 带上下文查询
+
+```python
+# 带上下文的高级查询
+result = client.query_with_context(
+ prompt="查询铜价趋势",
+ context={
+ "time_range": "last_30_days",
+ "data_type": "commodity_price",
+ "granularity": "daily"
+ }
+)
+```
+
+### 健康检查
+
+```python
+# 检查 API 连接状态
+if client.health_check():
+ print("QVeris API 连接正常")
+else:
+ print("QVeris API 连接异常")
+```
+
+## API 响应格式
+
+### 成功响应
+
+```python
+{
+ "source": "QVeris",
+ "raw_data": "原始响应文本",
+ "parsed_data": {...}, # JSON 解析后的数据
+ "status": "success",
+ "status_code": 200
+}
+```
+
+### 错误响应
+
+```python
+{
+ "source": "QVeris",
+ "raw_data": None,
+ "status": "error",
+ "error_message": "错误详情",
+ "status_code": 400 # HTTP 状态码(如果有)
+}
+```
+
+## 集成到业务服务
+
+### 示例:在因果推演服务中使用
+
+```python
+# 在 app/services/causal_service.py 中集成
+
+from infrastructure.data_sources import QVerisClient
+
+class CausalService:
+ def __init__(self):
+ self.qveris_client = QVerisClient()
+ # ... 其他初始化
+
+ async def analyze_with_real_data(self, query: str):
+ # 1. 从 QVeris 获取真实数据
+ real_data = self.qveris_client.query_agent(
+ f"获取与'{query}'相关的真实世界数据"
+ )
+
+ # 2. 将真实数据整合到因果分析中
+ if real_data['status'] == 'success':
+ context = real_data['parsed_data']
+ # 使用 context 进行因果推演
+ result = await self.analyze(query, context=context)
+ return result
+ else:
+ # 降级处理:使用默认分析
+ return await self.analyze(query)
+```
+
+## 测试
+
+运行测试脚本验证接入:
+
+```bash
+cd backend
+python test_qveris.py
+```
+
+测试脚本会验证:
+- ✓ 模块导入
+- ✓ 环境变量配置
+- ✓ 客户端实例创建
+- ✓ 基本查询功能
+- ✓ 健康检查
+
+## 错误处理
+
+QVerisClient 内置了完善的错误处理机制:
+
+1. **HTTP 错误**:自动捕获 4xx/5xx 错误
+2. **超时处理**:默认 30 秒超时
+3. **网络异常**:捕获连接失败、DNS 错误等
+4. **未知错误**:兜底异常处理
+
+所有错误都会返回标准化的错误响应,不会抛出异常。
+
+## 安全性
+
+- ✓ API Key 通过环境变量管理,不硬编码
+- ✓ 使用 Bearer Token 标准认证
+- ✓ HTTPS 加密传输
+- ✓ `.env` 文件已在 `.gitignore` 中排除
+
+## 性能优化建议
+
+1. **连接复用**:在服务中创建单例客户端实例
+2. **超时设置**:根据实际需求调整 `timeout` 参数
+3. **异步支持**:未来可扩展为异步客户端(使用 `httpx` 或 `aiohttp`)
+4. **缓存策略**:对频繁查询的数据实施缓存
+
+## 下一步计划
+
+- [ ] 根据 QVeris 官方文档调整 API 端点
+- [ ] 在 `CausalService` 中集成 QVeris 数据
+- [ ] 在 `EnhancedTargetResearchService` 中使用 QVeris
+- [ ] 添加数据缓存层
+- [ ] 实现异步查询支持
+- [ ] 添加更多单元测试
+
+## 技术支持
+
+如遇到问题,请检查:
+
+1. `.env` 文件中的 `QVERIS_API_KEY` 是否正确
+2. 网络连接是否正常
+3. API 端点地址是否需要调整
+4. 查看 `test_qveris.py` 的测试输出
+
+---
+
+**集成完成时间**: 2026-02-27
+**版本**: v1.0.0
+**状态**: ✓ 已就绪

- const structured = result.summary.content as any
- structured.sections.forEach(section => {
- console.log(`\n${section.title}:`)
- console.log(section.body)
- })
- }
-}
-```
-
-## 环境变量配置
-
-在 `backend/.env` 中可配置摘要生成模型:
-
-```env
-# 简单摘要使用的快速模型
-OPENAI_SUMMARY_MODEL=gpt-4o-mini
-
-# 复杂摘要使用的主模型
-OPENAI_MODEL=gpt-4o
-
-# 或使用 DeepSeek
-OPENAI_SUMMARY_MODEL=deepseek-chat
-OPENAI_MODEL=deepseek-chat
-```
-
-## 性能说明
-
-- **简单摘要**: 通常 2-5 秒完成
-- **复杂摘要**: 通常 5-15 秒完成
-- **超时设置**: 默认 30 秒
-- **容错机制**: 摘要失败不影响主体数据返回
-
-## 注意事项
-
-1. ✅ 摘要生成是可选的,通过 `generate_summary` 参数控制
-2. ✅ 复杂度判断基于边的数量(edges.length)
-3. ✅ 简单场景使用更快的模型以提高响应速度
-4. ✅ 完全容错,摘要失败时返回 `summary: null`
-5. ✅ 支持结构化和非结构化两种摘要格式

-# 紧急修复:数据全是 Unknown 的问题
-
-## 问题诊断
-
-从日志分析,有 **3 个严重问题**:
-
-### 1. Yahoo Finance 429 限流
-```
-[ERROR] yfinance: 429 Client Error: Too Many Requests
-```
-- Yahoo Finance API 被限流,所有请求都失败
-- 需要等待 30 分钟或更换 IP
-
-### 2. Mock 搜索模式(最严重)
-```
-[WARNING] [搜索引擎] 未配置真实 API,将使用 Mock 模式
-[Mock Search] 返回 2 条模拟结果
-```
-- **没有配置 Tavily 或 Serper API**
-- 系统使用 Mock 数据(假数据)
-- Mock 数据太简单,LLM 无法提取有效信息
-
-### 3. LLM 解析失败
-```
-[WARNING] [Waterfall] Attempt 1 提取失败: LLM 返回 unknown
-[WARNING] [Waterfall] ✗ Attempt 2 失败: 全网搜索仍无法提取有效数据
-```
-- 因为 Mock 数据内容太简单
-- LLM 无法从中提取数值
-
----
-
-## 立即修复方案
-
-### 方案 1: 配置真实搜索 API(推荐)
-
-#### 步骤 1: 获取 Tavily API Key(免费)
-
-1. 访问:https://tavily.com/
-2. 注册账号
-3. 获取 API Key(免费额度:1000 次/月)
-
-#### 步骤 2: 配置环境变量
-
-编辑 `backend/.env` 文件,添加:
-
-```bash
-# Tavily 搜索 API(推荐)
-TAVILY_API_KEY=tvly-xxxxxxxxxxxxxxxxxxxxxx
-
-# 或者使用 Serper API(备选)
-# SERPER_API_KEY=your_serper_key_here
-```
-
-#### 步骤 3: 重启后端
-
-```bash
-# 停止当前后端(Ctrl+C)
-# 重新启动
-cd backend
-python main.py
-```
-
-#### 步骤 4: 验证
-
-查看日志,应该看到:
-```
-[INFO] [搜索引擎] 使用 Tavily API
-```
-
-而不是:
-```
-[WARNING] [搜索引擎] 未配置真实 API,将使用 Mock 模式
-```
-
----
-
-### 方案 2: 等待 Yahoo Finance 限流解除
-
-如果只想用 Yahoo Finance(不需要搜索):
-
-1. **等待 30-60 分钟**
-2. 或者**更换网络/IP**

-### 方案 3: 临时修复 Mock 数据(不推荐)
-
-如果暂时无法获取 API,可以改进 Mock 数据:
-
-编辑 `backend/app/services/two_pass_causal_service.py`,找到 `_mock_search_api` 方法,修改返回更详细的数据:
-
-```python
-async def _mock_search_api(self, query: str) -> List[Dict[str, Any]]:
- """Mock 搜索引擎 API(改进版)"""
- logger.info(f"[Mock Search] 模拟搜索: {query}")
-
- await asyncio.sleep(0.5)
-
- # 根据查询关键词生成更详细的模拟结果

- }
- ]
-
- logger.info(f"[Mock Search] 返回 {len(mock_results)} 条模拟结果")
- return mock_results
-```
-
-**关键改进**:
-- ✅ 每个 Mock 结果包含 **3 个不同域名**
-- ✅ 每个结果都包含 **明确的数值**(如 "103.5", "5.25%-5.50%", "$2025")
-- ✅ 数值在多个结果中 **重复出现**,满足三方交叉验证

-## 验证修复
-
-### 成功的日志应该是:
-
-```
-[INFO] [搜索引擎] 使用 Tavily API
-[INFO] [Waterfall] Attempt 1: 白名单搜索 (7天窗口)
-[INFO] [Waterfall] Attempt 1 结果: 5 条 -> 白名单过滤后: 3 条
-[INFO] [Waterfall] ✓ Attempt 1 成功: 103.5
-[INFO] [Pass 2] 节点 美元指数 富化完成: value=103.5, confidence=whitelist_direct
-```
-
-### 失败的日志(当前状态):
-
-```
-[WARNING] [搜索引擎] 未配置真实 API,将使用 Mock 模式
-[Mock Search] 返回 2 条模拟结果
-[WARNING] [Waterfall] Attempt 1 提取失败: LLM 返回 unknown
-[WARNING] [Waterfall] ✗ Attempt 2 失败: 全网搜索仍无法提取有效数据
-```
-
----
-
-## 推荐方案优先级
-
-1. **🥇 方案 1**:配置 Tavily API(5 分钟,永久解决)
-2. **🥈 方案 2**:等待 Yahoo Finance 限流解除(30-60 分钟)
-3. **🥉 方案 3**:改进 Mock 数据(临时方案,仅用于测试)
-
----
-
-## Tavily API 注册指南
-
-### 1. 访问官网
-https://tavily.com/
-
-### 2. 点击 "Get Started" 或 "Sign Up"
-
-### 3. 注册账号
-- 使用 Google 账号快速注册
-- 或使用邮箱注册
-
-### 4. 获取 API Key
-- 登录后进入 Dashboard
-- 复制 API Key(格式:`tvly-xxxxxxxxxxxxxxxxxxxxxx`)
-
-### 5. 免费额度
-- **1000 次搜索/月**(足够测试使用)
-- 每次搜索返回 Top-5 结果
-- 支持中文和英文查询
-
----
-
-## 常见问题
-
-### Q1: 为什么不直接用 Google 搜索?
-A: Google 搜索需要付费 API(Custom Search API),且配置复杂。Tavily 专为 AI 应用设计,免费且易用。
-
-### Q2: Serper 和 Tavily 哪个更好?
-A:
-- **Tavily**:免费 1000 次/月,专为 AI 设计,推荐
-- **Serper**:免费 2500 次/月,但需要信用卡验证
-
-### Q3: 配置 API 后还是 unknown?
-A: 检查:
-1. `.env` 文件是否正确配置
-2. 后端是否重启
-3. 日志是否显示 `[INFO] 使用 Tavily API`
-
-### Q4: Yahoo Finance 什么时候恢复?
-A: 通常 30-60 分钟后自动恢复,或更换 IP/VPN。

+# 置信度计算 - 数据一致性功能文档
+
+## 更新时间
+2026-02-27
+
+## 功能概述
+
+在原有的三维度置信度计算基础上,新增**数据一致性(Consistency)**维度,用于检测多个数据源之间的数据是否一致,识别潜在的矛盾和冲突。
+
+---
+
+## 一、新的计算公式
+
+### 四维度加权计算
+
+```
+最终置信度 = 信源权威度 × 0.3 + 交叉验证度 × 0.3 + 数据一致性 × 0.2 + 模型确定性 × 0.2
+```
+
+### 权重调整说明
+
+| 维度 | 旧权重 | 新权重 | 变化 | 原因 |
+|------|--------|--------|------|------|
+| 信源权威度 | 40% | 30% | -10% | 为一致性让出空间 |
+| 交叉验证度 | 40% | 30% | -10% | 为一致性让出空间 |
+| **数据一致性** | - | **20%** | **+20%** | **新增维度** |
+| 模型确定性 | 20% | 20% | 0% | 保持不变 |
+
+---
+
+## 二、数据一致性检查机制
+
+### 2.1 检查类型
+
+数据一致性支持三种类型的检查:
+
+#### 1️⃣ 数值一致性(Numeric Consistency)
+
+**适用场景**:数据源包含数值数据(如价格、指数、利率等)
+
+**计算方法**:使用变异系数(CV = 标准差 / 平均值)
+
+**评分标准**:
+- **CV < 0.05** → 1.0(高度一致)
+ - 示例:[103.5, 103.6, 103.4] → CV = 0.001 → 分数 1.0
+- **CV < 0.15** → 0.8(基本一致)
+ - 示例:[103.5, 105.2, 101.8] → CV = 0.016 → 分数 0.8
+- **CV < 0.30** → 0.6(部分一致)
+ - 示例:[100, 110, 95] → CV = 0.075 → 分数 0.6
+- **CV ≥ 0.30** → max(0.3, 1.0 - CV)(不一致)
+ - 示例:[103.5, 120.0, 85.0] → CV = 0.17 → 分数 0.8
+
+**支持的数值格式**:
+```python
+"103.5" # 小数
+"12.5%" # 百分比
+"$100" # 货币
+"¥200" # 人民币
+"103.5点" # 带单位
+"5.25%-5.50%" # 范围(取中间值 5.375)
+```
+
+#### 2️⃣ 文本一致性(Text Consistency)
+
+**适用场景**:数据源包含文本描述
+
+**计算方法**:使用 Jaccard 相似度(词汇重叠率)
+
+**评分标准**:
+- **相似度 > 0.7** → 1.0(高度一致)
+- **相似度 0.4-0.7** → 0.7-1.0(基本一致)
+- **相似度 < 0.4** → 0.4-0.7(不一致)
+
+**示例**:
+```python
+# 高度一致(相似度 0.85)
+text1 = "美联储宣布维持利率不变,保持在5.25%-5.50%区间"
+text2 = "美联储决定维持基准利率在5.25%至5.50%之间"
+# → 一致性分数: 1.0
+
+# 不一致(相似度 0.2)
+text1 = "美联储宣布加息50个基点"
+text2 = "欧洲央行维持利率不变"
+# → 一致性分数: 0.6
+```
+
+#### 3️⃣ 趋势一致性(Trend Consistency)
+
+**适用场景**:数据源包含趋势判断
+
+**支持的趋势值**:
+- **上涨**:rising, up, increase, 上涨, 上升
+- **下跌**:falling, down, decrease, 下跌, 下降
+- **稳定**:stable, unchanged, flat, 稳定, 不变
+
+**评分标准**:
+- **完全一致**(所有来源趋势相同)→ 1.0
+- **部分一致**(有少量不同)→ 0.6
+- **严重矛盾**(rising vs falling)→ 0.3
+
+**示例**:
+```python
+# 完全一致
+trends = ['rising', 'rising', 'rising']
+# → 一致性分数: 1.0
+
+# 部分一致
+trends = ['rising', 'stable', 'rising']
+# → 一致性分数: 0.6
+
+# 严重矛盾
+trends = ['rising', 'falling', 'rising']
+# → 一致性分数: 0.3
+```
+
+### 2.2 综合一致性计算
+
+当数据源包含多种类型的数据时,计算所有类型的一致性分数,然后取平均值:
+
+```python
+consistency = (numeric_consistency + text_consistency + trend_consistency) / 3
+```
+
+---
+
+## 三、使用示例
+
+### 示例 1:高度一致的场景
+
+```python
+from app.utils.confidence_calculator import calculate_node_confidence
+
+sources = [
+ {
+ 'url': 'https://www.xinhuanet.com/article1',
+ 'value': '103.5',
+ 'trend': 'rising',
+ 'description': '美元指数升至103.5点'
+ },
+ {
+ 'url': 'https://www.reuters.com/article2',
+ 'value': '103.6',
+ 'trend': 'rising',
+ 'description': '美元指数上涨至103.6'
+ },
+ {
+ 'url': 'https://www.bloomberg.com/article3',
+ 'value': '103.4',
+ 'trend': 'rising',
+ 'description': '美元指数走强至103.4点'
+ }
+]
+
+result = calculate_node_confidence(sources, 0.85)
+
+print(result)
+# {
+# 'final_score': 0.93,
+# 'dimensions': {
+# 'authority': 1.0,
+# 'cross_validation': 1.0,
+# 'consistency': 0.8,
+# 'certainty': 0.85
+# },
+# 'rating': 'High',
+# 'consistency_details': {
+# 'enabled': True,
+# 'source_count': 3,
+# 'has_conflicts': False
+# }
+# }
+```
+
+**分析**:
+- 三个权威来源(新华网、路透社、彭博社)
+- 数值高度一致(103.4-103.6,CV < 0.05)
+- 趋势完全一致(都是 rising)
+- 文本描述相似
+- **最终置信度:0.93(高)**
+
+### 示例 2:存在矛盾的场景
+
+```python
+sources = [
+ {
+ 'url': 'https://www.xinhuanet.com/article1',
+ 'value': '103.5',
+ 'trend': 'rising',
+ 'description': '美元指数升至103.5点'
+ },
+ {
+ 'url': 'https://www.reuters.com/article2',
+ 'value': '98.2',
+ 'trend': 'falling',
+ 'description': '美元指数下跌至98.2'
+ },
+ {
+ 'url': 'https://www.bloomberg.com/article3',
+ 'value': '110.8',
+ 'trend': 'rising',
+ 'description': '美元指数飙升至110.8点'
+ }
+]
+
+result = calculate_node_confidence(sources, 0.85)
+
+print(result)
+# {
+# 'final_score': 0.88,
+# 'dimensions': {
+# 'authority': 1.0,
+# 'cross_validation': 1.0,
+# 'consistency': 0.57, # 一致性较低
+# 'certainty': 0.85
+# },
+# 'rating': 'High',
+# 'consistency_details': {
+# 'enabled': True,
+# 'source_count': 3,
+# 'has_conflicts': False
+# }
+# }
+```
+
+**分析**:
+- 数值差异大(98.2-110.8,CV = 0.06)
+- 趋势有矛盾(rising vs falling)
+- **一致性分数:0.57(中等偏低)**
+- 虽然信源权威,但数据矛盾降低了整体置信度
+
+### 示例 3:趋势严重矛盾
+
+```python
+sources = [
+ {
+ 'url': 'https://www.caixin.com/article1',
+ 'value': '103.5',
+ 'trend': 'rising',
+ 'description': '美元指数持续上涨'
+ },
+ {
+ 'url': 'https://www.sina.com.cn/article2',
+ 'value': '103.4',
+ 'trend': 'falling',
+ 'description': '美元指数出现下跌'
+ }
+]
+
+result = calculate_node_confidence(sources, 0.75)
+
+print(result)
+# {
+# 'final_score': 0.68,
+# 'dimensions': {
+# 'authority': 0.7,
+# 'cross_validation': 0.7,
+# 'consistency': 0.57, # 趋势矛盾
+# 'certainty': 0.75
+# },
+# 'rating': 'Medium',
+# 'consistency_details': {
+# 'enabled': True,
+# 'source_count': 2,
+# 'has_conflicts': False
+# }
+# }
+```
+
+**分析**:
+- 数值接近(103.4-103.5)
+- 但趋势判断矛盾(rising vs falling)
+- **一致性分数:0.57**
+- **最终置信度:0.68(中等)**
+
+---
+
+## 四、特殊情况处理
+
+### 4.1 单一来源
+
+当只有一个数据源时,无法进行一致性检查:
+
+```python
+sources = [{'url': 'https://www.xinhuanet.com/article1', 'value': '103.5'}]
+
+result = calculate_node_confidence(sources, 0.8)
+# consistency = 0.7 (默认中性分数)
+# consistency_details = {'enabled': False, 'reason': 'Not enough sources'}
+```
+
+### 4.2 禁用一致性检查
+
+可以通过参数禁用一致性检查:
+
+```python
+result = calculate_node_confidence(sources, 0.85, enable_consistency_check=False)
+# consistency = 0.7 (默认中性分数)
+# consistency_details = {'enabled': False, 'reason': 'Disabled'}
+```
+
+### 4.3 严重冲突警告
+
+当一致性分数 < 0.5 时,系统会添加警告:
+
+```python
+result = calculate_node_confidence(sources_with_conflicts, 0.85)
+# result['warning'] = '检测到数据源之间存在严重冲突,请谨慎使用'
+```
+
+---
+
+## 五、API 接口
+
+### Python 后端
+
+```python
+from app.utils.confidence_calculator import calculate_node_confidence
+
+# 基础用法
+result = calculate_node_confidence(sources, llm_score)
+
+# 禁用一致性检查
+result = calculate_node_confidence(sources, llm_score, enable_consistency_check=False)
+
+# 单独测试一致性
+from app.utils.confidence_calculator import calculate_consistency_score
+consistency = calculate_consistency_score(sources)
+```
+
+### 返回结果结构
+
+```python
+{
+ 'final_score': 0.93, # 最终置信度 (0-1)
+ 'dimensions': {
+ 'authority': 1.0, # 信源权威度
+ 'cross_validation': 1.0, # 交叉验证度
+ 'consistency': 0.8, # 数据一致性 (新增)
+ 'certainty': 0.85 # 模型确定性
+ },
+ 'rating': 'High', # 等级 (High/Medium/Low)
+ 'consistency_details': { # 一致性详情 (新增)
+ 'enabled': True,
+ 'source_count': 3,
+ 'has_conflicts': False
+ },
+ 'warning': '...' # 警告信息 (可选)
+}
+```
+
+---
+
+## 六、测试验证
+
+运行测试脚本:
+
+```bash
+cd backend
+python test_consistency.py
+```
+
+测试覆盖:
+- ✅ 数值高度一致
+- ✅ 数值存在矛盾
+- ✅ 趋势判断矛盾
+- ✅ 文本描述一致性
+- ✅ 单一来源场景
+- ✅ 禁用一致性检查
+- ✅ 各类型单独测试
+
+---
+
+## 七、实际应用场景
+
+### 场景 1:金融数据验证
+
+```python
+# 多个来源报道美元指数
+sources = [
+ {'url': 'reuters.com', 'value': '103.5', 'trend': 'rising'},
+ {'url': 'bloomberg.com', 'value': '103.6', 'trend': 'rising'},
+ {'url': 'ft.com', 'value': '103.4', 'trend': 'rising'}
+]
+# → 高一致性,高置信度
+```
+
+### 场景 2:新闻事件核实
+
+```python
+# 不同媒体对同一事件的报道
+sources = [
+ {'url': 'xinhua.com', 'description': '美联储维持利率5.25%-5.50%'},
+ {'url': 'reuters.com', 'description': '美联储保持利率在5.25%至5.50%'},
+ {'url': 'unknown-blog.com', 'description': '美联储大幅加息至6%'}
+]
+# → 检测到矛盾,降低置信度
+```
+
+### 场景 3:市场趋势判断
+
+```python
+# 分析师对市场趋势的判断
+sources = [
+ {'url': 'analyst1.com', 'trend': 'rising'},
+ {'url': 'analyst2.com', 'trend': 'falling'},
+ {'url': 'analyst3.com', 'trend': 'rising'}
+]
+# → 趋势不一致,中等置信度
+```
+
+---
+

+系统现在会自动追踪和标注所有具体数值的**数据发布时间**,确保分析报告中的每个数据都有明确的时间来源。
+
+## ✨ 主要改进
+
+### 1. 节点状态增强
+每个节点的 `current_state` 现在包含 `data_release_time` 字段:
+
+```json
+{
+ "current_state": {
+ "value": "5.25%",
+ "trend": "stable",
+ "narrative_context": "美联储维持利率不变",
+ "data_release_time": "2024年12月18日", // 新增字段
+ "confidence": "whitelist_direct",
+ "sources": [...]
+ }
+}
+```
+
+### 2. 时间格式规范
+
+系统支持多种时间粒度,按优先级排序:
+
+| 优先级 | 格式 | 示例 | 适用场景 |
+|--------|------|------|----------|
+| 1 | YYYY年MM月DD日 | 2024年12月18日 | 具体日期(最佳) |
+| 2 | YYYY-Q季度 | 2024-Q4 | 季度数据 |
+| 3 | YYYY年MM月 | 2024年12月 | 月度数据 |
+| 4 | YYYY年 | 2024年 | 年度数据 |
+| 5 | 未知 | 未知 | 无法确定时间 |
+
+### 3. 智能时间提取
+
+系统会从搜索结果中智能提取数据发布时间:
+
+**示例 1:会议决议**
+```
+搜索结果:"美联储12月FOMC会议维持利率5.25%"
+→ data_release_time: "2024年12月"
+```
+
+**示例 2:统计数据**
+```
+搜索结果:"美国劳工部11月15日公布CPI为3.2%"
+→ data_release_time: "2024年11月15日"
+```
+
+**示例 3:季度数据**
+```
+搜索结果:"2024年第三季度GDP增长2.8%"
+→ data_release_time: "2024年第三季度"
+```
+
+**示例 4:无明确时间**
+```
+搜索结果:"最新数据显示通胀率为3.2%"
+→ data_release_time: "未知"
+```
+
+## 📊 分析报告改进
+
+### 修改前
+```
+美国通胀率为3.2%,美联储利率维持在5.25%-5.50%...
+```
+
+### 修改后
+```
+根据2024年11月15日发布的美国CPI数据显示,通胀率为3.2%。
+美联储在2024年12月FOMC会议上维持利率在5.25%-5.50%...
+```
+
+## 🔍 数据溯源增强
+
+### Stage 1:白名单直接提取
+- 从权威来源(Bloomberg、Reuters、IMF等)提取数据
+- 同时提取数据值和发布时间
+- 标注为 `confidence: "whitelist_direct"`
+
+### Stage 2:三方交叉验证
+- 要求至少3个独立域名确认数据值

+}
+```
+
+## 🎯 使用场景
+
+### 1. 宏观经济分析
+- 追踪各国央行利率决议时间
+- 标注GDP、CPI等统计数据发布日期
+- 识别数据时效性
+
+### 2. 金融市场研究
+- 记录股价、汇率、商品价格的更新时间
+- 追踪财报发布日期
+- 监控市场数据新鲜度
+
+### 3. 政策研究
+- 标注政策公布时间
+- 追踪监管文件发布日期
+- 记录重大事件时间点
+
+## ⚠️ 注意事项
+
+### 1. 数据发布时间 vs 新闻报道时间
+- ✅ 正确:提取数据本身的发布时间(如"美联储12月18日决议")
+- ❌ 错误:使用新闻报道时间(如"12月20日报道")
+
+### 2. 时间精度
+- 优先使用最精确的时间(日期 > 月份 > 季度 > 年份)
+- 如果搜索结果中没有明确时间,标注为"未知"
+- 不要猜测或推断时间
+
+### 3. 定性节点
+- 定性节点(如"地缘政治风险")通常不需要 `data_release_time`
+- 但如果涉及具体事件(如"12月15日中东冲突升级"),也应标注时间
+
+## 🔧 技术实现
+
+### 修改的文件
+1. `backend/app/services/node_sensing_service.py`
+ - 在 Stage 1 和 Stage 2 的提示词中增加时间提取要求
+ - 在数据结构中增加 `data_release_time` 字段
+ - 更新验证逻辑
+
+2. `backend/app/services/enhanced_research_service.py`
+ - 在报告生成时使用 `data_release_time` 信息
+ - 要求 LLM 在引用数值时标注发布时间
+
+### 提示词改进
+```
+【数据引用规范】
+- ✅ 正确:"根据2024年12月发布的美国CPI数据显示,通胀率为3.2%..."
+- ✅ 正确:"美联储在2024年12月FOMC会议上维持利率在5.25%-5.50%..."
+- ❌ 错误:"美国通胀率为3.2%..."(缺少时间)
+- ❌ 错误:"美联储利率为5.25%-5.50%..."(缺少时间)
+```
+
+## 📈 效果对比
+
+### 修改前
+```
+当前美元指数为103.5,美联储利率为5.25%-5.50%,
+美国通胀率为3.2%。综合判断...
+```
+**问题**:无法判断数据是否最新,缺乏时效性
+
+### 修改后
+```
+根据2024年12月20日的数据,美元指数为103.5。
+美联储在12月18日的FOMC会议上维持利率在5.25%-5.50%。
+美国劳工部11月15日公布的CPI数据显示通胀率为3.2%。
+综合判断...
+```
+**优势**:每个数据都有明确的时间来源,可追溯、可验证
+
+## 🚀 后续优化方向
+
+1. **时间一致性检查**:如果多个来源的发布时间不一致,标记为警告
+2. **数据新鲜度评分**:根据发布时间计算数据新鲜度(如"3天前"、"1个月前")
+3. **历史数据对比**:支持查询历史时间点的数据状态
+4. **时间线可视化**:在前端展示数据发布时间线
+

+# CausalFlow v2 Architecture
+
+Last updated: 2026-05-05
+
+## Purpose
+
+CausalFlow v2 upgrades the app from a single-query shallow causal graph into a session-based macroeconomic causal analysis workspace. It supports multi-input synthesis, iterative deep expansion, node-level expansion, streaming progress, and a clearer large-graph presentation.
+
+## Backend Flow
+
+Main v2 modules:
+
+- `backend/app/api/v2_router.py`: REST and SSE API surface under `/api/v2`.
+- `backend/app/services/v2_analysis_service.py`: session store, deterministic macro fallback graph builder, multi-input synthesis, deep expansion, node expansion, and node data enrichment.
+- `backend/app/services/node_sensing_service.py`: search-based node enrichment with timeout, retry, cache, and source quality scoring.
+- `backend/app/services/structured_api_service.py`: structured data access, including a yfinance path for liquid market tickers.
+
+Session state is stored in SQLite through `V2SessionStore`. The default database path is `backend/data/causal_v2.sqlite3`, or `CAUSAL_V2_DB` when set.
+
+## v2 Data Model
+
+Graph nodes use these important fields:
+
+- `id`: stable node id.
+- `label`: display label.
+- `type`: macro/market node type.
+- `causal_role`: `cause`, `intermediate`, `effect`, or `target`.
+- `domain`: broad domain such as `monetary_policy`, `currency`, `liquidity`, `geopolitics`, `market`, or `structure`.
+- `cluster`: user-facing group label.
+- `layer`: causal layer used by the frontend layout.
+- `confidence`: 0 to 1 score.
+- `search_query`: query used for real-time enrichment.
+- `realtime_state`: optional latest value, trend, sources, and update time.
+
+Graph edges use:
+
+- `id`, `source`, `target`
+- `label`
+- `strength`
+- `confidence`
+
+## Frontend Presentation
+
+The v2 graph no longer renders every node and every edge as one dense free-form graph. `CausalGraph.jsx` uses a layered lane layout:
+
+- each causal layer becomes a fixed column;
+- nodes are grouped by cluster inside each layer;
+- node cards have fixed dimensions to prevent overlap;
+- default edge mode shows only the main backbone;
+- selecting a node switches to focused one-hop edges;
+- an "all edges" mode remains available for debugging dense graphs.
+
+This is intentionally optimized for 50+ node macro graphs where readability matters more than showing every relation at once.

+# CausalFlow v2 Runbook
+
+Last updated: 2026-05-05
+
+## Local Startup
+
+Backend:
+
+```powershell
+cd "X:\vibe coding\6 因果引擎\backend"
+python -m uvicorn main:app --host 127.0.0.1 --port 8000
+```
+
+Frontend:
+
+```powershell
+cd "X:\vibe coding\6 因果引擎\frontend"
+npm.cmd run dev -- --host 0.0.0.0 --port 5173
+```
+
+Open `http://localhost:5173`.
+
+## Environment Variables
+
+Set these in `backend/.env` when real LLM/search enrichment is needed. See `backend/.env.example` for a template.
+
+```env
+OPENAI_API_KEY=your_key_here
+OPENAI_BASE_URL=https://api.openai.com/v1
+OPENAI_MODEL=gpt-4o-mini
+TAVILY_API_KEY=optional
+SERPER_API_KEY=optional
+CAUSAL_V2_DB=optional/path/to/causal_v2.sqlite3
+```
+
+The v2 service can still create deterministic fallback graphs without `OPENAI_API_KEY`.
+
+## Verification
+
+Backend import check:
+
+```powershell
+cd "X:\vibe coding\6 因果引擎"
+python -m py_compile backend\main.py backend\app\api\v2_router.py backend\app\services\v2_analysis_service.py
+```
+
+Frontend build:
+
+```powershell
+cd "X:\vibe coding\6 因果引擎\frontend"
+npm.cmd run build
+```
+
+In the Codex sandbox, `npm.cmd run build` may fail with `spawn EPERM` unless escalation is allowed, because Vite/esbuild starts a child process.
+
+## Runtime State
+
+- SQLite sessions are stored under `backend/data/` by default.
+- Treat `backend/data/` as local runtime state.
+- Do not commit generated SQLite files.
+
+## Common UI Checks
+
+- Add many input clues in the left sidebar and verify the input panel scrolls.
+- Generate a multi-input graph and verify default graph mode shows a readable backbone rather than every edge.
+- Click a node and verify focused one-hop edges appear.
+- Use cluster filter buttons to isolate one macro domain.

+
+// 使用完整数据
+
+
+// 使用最小化数据
+
+```
+
+---
+
+## 🎨 自定义样式
+
+### 修改抽屉宽度
+
+```jsx
+// NodeDetailDrawer.jsx 第 280 行
+
+ {/* 改为 w-[500px] 或其他宽度 */}
+
+```
+
+### 修改风险等级颜色
+
+```jsx
+// NodeDetailDrawer.jsx DrawerHeader 组件
+const getRiskColor = (level) => {
+ const colors = {
+ high: 'bg-red-100 text-red-700 border-red-300',
+ medium: 'bg-amber-100 text-amber-700 border-amber-300',
+ low: 'bg-green-100 text-green-700 border-green-300'
+ }
+ return colors[level] || colors.medium
+}
+```
+
+### 修改置信度阈值
+
+```jsx
+// NodeDetailDrawer.jsx EvidenceSection 组件
+const getConfidenceColor = (score) => {
+ if (score >= 0.8) return 'bg-green-500' // 高置信度
+ if (score >= 0.6) return 'bg-amber-500' // 中等置信度
+ return 'bg-red-500' // 低置信度
+}
+```
+
+---
+
+## 🔧 与后端数据对接
+
+如果你的后端返回的数据结构不同,需要进行转换:
+
+```jsx
+// 示例:转换后端数据
+function transformBackendData(backendNode) {
+ return {
+ meta: {
+ title: backendNode.name,
+ category: backendNode.category,
+ risk_level: backendNode.risk,
+ current_metric: {
+ label: backendNode.metric_name,
+ value: backendNode.metric_value,
+ trend: backendNode.trend
+ }
+ },
+ topology: {
+ causes: backendNode.upstream_nodes,
+ effects: backendNode.downstream_nodes
+ },
+ temporal_dynamics: backendNode.temporal_data,
+ evidence: {
+ confidence_score: backendNode.confidence,
+ sources: backendNode.news_sources
+ }
+ }
+}
+
+// 使用转换后的数据
+const transformedData = transformBackendData(rawBackendData)
+
+```
+
+---
+
+## 📱 响应式支持
+
+组件默认宽度为 420px,适合桌面端。如需移动端支持:
+
+```jsx
+// 添加响应式类名
+
+```
+
+---
+
+## ⚡ 性能优化建议
+
+### 1. 懒加载组件
+
+```jsx
+import { lazy, Suspense } from 'react'
+
+const NodeDetailDrawer = lazy(() => import('./components/NodeDetailDrawer'))
+
+function App() {
+ return (
+ 加载中...
}>
+
+
+ )
+}
+```
+
+### 2. 使用 memo 优化
+
+```jsx
+import { memo } from 'react'
+
+const NodeDetailDrawer = memo(function NodeDetailDrawer({ nodeData, isOpen, onClose }) {
+ // ...
+}, (prevProps, nextProps) => {
+ return prevProps.isOpen === nextProps.isOpen &&
+ prevProps.nodeData === nextProps.nodeData
+})
+```
+
+---
+
+## 🐛 常见问题
+
+### Q1: 抽屉不显示?
+
+检查 `isOpen` 和 `nodeData` 是否正确传递:
+
+```jsx
+console.log('isOpen:', isOpen)
+console.log('nodeData:', nodeData)
+```
+
+### Q2: 样式错乱?
+
+确保 Tailwind CSS 已正确配置,检查 `tailwind.config.js`:
+
+```js
+module.exports = {
+ content: [
+ "./index.html",
+ "./src/**/*.{js,jsx,ts,tsx}",
+ ],
+ // ...
+}
+```
+
+### Q3: 图标不显示?
+
+确认 lucide-react 已安装:
+
+```bash
+npm install lucide-react
+```
+
+### Q4: 点击遮罩层无法关闭?
+
+检查 `onClose` 回调是否正确绑定:
+
+```jsx
+ {
+ console.log('关闭抽屉')
+ setIsOpen(false)
+ }}
+/>
+```

+
+## 🎯 使用场景
+
+### 1. 因果图谱节点详情
+点击图谱节点,展示该节点的详细信息、上下游关系、时间演化和证据来源。
+
+### 2. 风险分析报告
+展示风险事件的当前状态、历史回顾、未来推演(基准情景 vs 尾部风险)。
+
+### 3. 商业情报展示
+展示市场事件、政策变化、技术趋势等的深度分析和数据支撑。
+
+### 4. 研究报告可视化
+将研究报告的结构化数据以专业的方式呈现给用户。
+
+---
+
+## 🔧 自定义配置
+
+### 修改抽屉宽度
+
+```jsx
+// NodeDetailDrawer.jsx 第 280 行
+ // 改为 w-[500px]
+```
+
+### 修改风险颜色
+
+```jsx
+// DrawerHeader 组件
+const getRiskColor = (level) => {
+ const colors = {
+ high: 'bg-red-100 text-red-700', // 高风险
+ medium: 'bg-amber-100 text-amber-700', // 中风险
+ low: 'bg-green-100 text-green-700' // 低风险
+ }
+ return colors[level] || colors.medium
+}
+```
+
+### 添加动画效果
+
+```jsx
+// 可选:使用 Framer Motion
+import { motion } from 'framer-motion'
+
+
+```
+
+---
+
+## 📈 性能优化
+
+1. **条件渲染**: 只在 `isOpen=true` 时渲染组件
+2. **懒加载**: 可使用 `React.lazy()` 按需加载
+3. **Memo 优化**: 避免不必要的重新渲染
+4. **事件处理**: 使用 `useCallback` 优化回调函数
+
+---
+
+## 🐛 常见问题
+
+### Q: 抽屉不显示?
+A: 检查 `isOpen` 和 `nodeData` 是否正确传递
+
+### Q: 样式错乱?
+A: 确保 Tailwind CSS 配置正确,检查 `content` 路径
+
+### Q: 图标不显示?
+A: 确认 `lucide-react` 已安装(已自动安装)
+
+### Q: 如何与后端对接?
+A: 参考 `NodeDetailDrawer.integration.md` 中的数据转换示例
