HaHafeng f0736dbca1 feat(asl/extraction): Complete Tool 3 M1+M2 - skeleton pipeline and HITL workbench
M1 Skeleton Pipeline:
- Scatter-dispatch + Aggregator polling pattern (PgBoss)
- PKB ACL bridge (PkbBridgeService -> PkbExportService DTOs)
- ExtractionSingleWorker with DeepSeek-V3 LLM extraction
- PermanentExtractionError for non-retryable failures
- Phantom Retry Guard (idempotent worker)
- 3-step minimal frontend (Setup -> Progress -> Workbench)
- 4 new DB tables (extraction_templates, project_templates, tasks, results)
- 3 system templates seed (RCT, Cohort, QC)
- M1 integration test suite

M2 HITL Workbench:
- MinerU VLM integration for high-fidelity table extraction
- XML-isolated DynamicPromptBuilder with flat JSON output template
- fuzzyQuoteMatch validator (3-tier confidence scoring)
- SSE real-time logging via ExtractionEventBus
- Schema-driven ExtractionDrawer (dynamic field rendering from template)
- Excel wide-table export with flattenModuleData normalization
- M2 integration test suite

Critical Fixes (data normalization):
- DynamicPromptBuilder: explicit flat key-value output format with example
- ExtractionExcelExporter: handle both array and flat data formats
- ExtractionDrawer: schema-driven rendering instead of hardcoded fields
- ExtractionValidator: array-format quote verification support
- SSE route: Fastify register encapsulation to bypass auth for EventSource
- LLM JSON sanitizer: strip illegal control chars before JSON.parse

Also includes: RVW stats verification spec, SSA expert config guide

Tested: M1 pipeline test + M2 HITL test + manual frontend verification

AI临床研究平台 - 后端服务

🏠 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:
