HaHafeng 11676f2840 fix(ssa): Fix 7 integration bugs and refactor frontend unified state management
Bug fixes:
- Fix garbled error messages in chat (TypeWriter rendering issue)
- Fix R engine NA crash in descriptive.R (defensive isTRUE/is.na checks)
- Fix intent misclassification for statistical significance queries
- Fix step 2 results not displayed (accept warning status alongside success)
- Fix incomplete R code download (only step 1 included)
- Fix multi-task state confusion (clicking old card shows new results)
- Add R engine and backend parameter logging for debugging

Refactor - Unified Record Architecture:
- Replace 12 global singleton fields with AnalysisRecord as single source of truth
- Remove isWorkflowMode branching across all components
- One Analysis = One Record = N Steps paradigm
- selectRecord only sets currentRecordId, all rendering derives from currentRecord
- Fix cross-hook-instance issue: executeWorkflow fallback to store currentRecordId

Updated files: ssaStore, useWorkflow, useAnalysis, SSAChatPane, SSAWorkspacePane,
SSACodeModal, WorkflowTimeline, QueryService, WorkflowExecutorService, descriptive.R

Tested: Manual integration test passed - multi-task switching, R code completeness

🏠 导航


快速开始

1. 环境要求

  • Node.js >= 18
  • PostgreSQL 15+
  • Redis 7+

2. 安装依赖

npm install

3. 配置环境变量

复制.env.example.env并配置:

cp .env.example .env

4. 初始化数据库

# 生成Prisma Client
npm run prisma:generate

# 执行数据库迁移
npm run prisma:migrate

# 可选打开Prisma Studio查看数据
npm run prisma:studio

5. 启动开发服务器

npm run dev

服务器将在 http://localhost:3001 启动

6. 验证服务

访问以下端点验证服务是否正常:
