HaHafeng beb7f7f559 feat(asl): Implement full-text screening core LLM service and validation system (Day 1-3)
Core Components:
- PDFStorageService with Dify/OSS adapters
- LLM12FieldsService with Nougat-first + dual-model + 3-layer JSON parsing
- PromptBuilder for dynamic prompt assembly
- MedicalLogicValidator with 5 rules + fault tolerance
- EvidenceChainValidator for citation integrity
- ConflictDetectionService for dual-model comparison

Prompt Engineering:
- System Prompt (6601 chars, Section-Aware strategy)
- User Prompt template (PICOS context injection)
- JSON Schema (12 fields constraints)
- Cochrane standards (not loaded in MVP)

Key Innovations:
- 3-layer JSON parsing (JSON.parse + json-repair + code block extraction)
- Promise.allSettled for dual-model fault tolerance
- safeGetFieldValue for robust field extraction
- Mixed CN/EN token calculation

Integration Tests:
- integration-test.ts (full test)
- quick-test.ts (quick test)
- cached-result-test.ts (fault tolerance test)

Documentation Updates:
- Development record (Day 2-3 summary)
- Quality assurance strategy (full-text screening)
- Development plan (progress update)
- Module status (v1.1 update)
- Technical debt (10 new items)

Test Results:
- JSON parsing success rate: 100%
- Medical logic validation: 5/5 passed
- Dual-model parallel processing: OK
- Cost per PDF: CNY 0.10

数据ETL引擎

能力定位: 通用能力层
复用率: 29% (2个模块依赖)
优先级: P2
状态: 待实现


📋 能力概述

数据ETL引擎负责

  • Excel多表JOIN
  • 数据清洗
  • 数据转换
  • 数据验证

📊 依赖模块

2个模块依赖29%复用率):

  1. DC - 数据清洗整理(核心依赖)
  2. SSA - 智能统计分析(数据预处理)

💡 核心功能

1. Excel多表处理

  • 读取多个Excel文件
  • 自动JOIN操作
  • GROUP BY聚合

2. 数据清洗

  • 缺失值处理
  • 重复值处理
  • 异常值检测

3. 数据转换

  • 类型转换
  • 格式标准化

🏗️ 技术方案

云端版(最优)

# 基于Polars性能极高
class ETLEngine:
    def read_excel(self, files: List[File]) -> List[DataFrame]
    def join(self, dfs: List[DataFrame], keys: List[str]) -> DataFrame
    def clean(self, df: DataFrame, rules: Dict) -> DataFrame
    def export(self, df: DataFrame, format: str) -> bytes

单机版(兼容)

# 基于SQLite内存友好
# 分块读取数据库引擎处理JOIN
