HaHafeng b47079b387 feat(iit): Phase 1.5 AI对话集成REDCap真实数据完成
- feat: ChatService集成DeepSeek-V3实现AI对话(390行)
- feat: SessionMemory实现上下文记忆(最近3轮对话,170行)
- feat: 意图识别支持REDCap数据查询(关键词匹配)
- feat: REDCap数据注入LLM(queryRedcapRecord, countRedcapRecords, getProjectInfo)
- feat: 解决LLM幻觉问题(基于真实数据回答,明确system prompt)
- feat: 即时反馈(正在查询...提示)
- test: REDCap查询测试通过(test0102项目,10条记录,ID 7患者详情)
- docs: 创建Phase1.5开发完成记录(313行)
- docs: 更新Phase1.5开发计划(标记完成)
- docs: 更新MVP开发任务清单(Phase 1.5完成)
- docs: 更新模块当前状态(60%完成度)
- docs: 更新系统总体设计文档(v2.6)
- chore: 删除测试脚本(test-redcap-query-for-ai.ts, check-env-config.ts)
- chore: 移除REDCap测试环境变量(REDCAP_TEST_*)

技术亮点:
- AI基于REDCap真实数据对话,不编造信息
- 从数据库读取项目配置,不使用环境变量
- 企业微信端测试通过,用户体验良好

测试通过:
-  查询项目记录总数(10条)
-  查询特定患者详情(ID 7)
-  项目信息查询
-  上下文记忆(3轮对话)
-  即时反馈提示

-- ==================== Postgres-Only 改造:手动迁移 ====================
-- 文件: 001_add_postgres_cache_and_checkpoint.sql
-- 目的: 添加缓存表和断点续传字段
-- 日期: 2025-12-13
-- 说明: 避免Prisma migrate的shadow database问题手动添加所需表和字段
-- ==================== 1. 创建缓存表 (AppCache) ====================
CREATE TABLE IF NOT EXISTS platform_schema.app_cache (
id SERIAL PRIMARY KEY,
key VARCHAR(500) UNIQUE NOT NULL,
value JSONB NOT NULL,
expires_at TIMESTAMP NOT NULL,
created_at TIMESTAMP DEFAULT NOW()
);
-- 创建索引优化过期查询和key查询
CREATE INDEX IF NOT EXISTS idx_app_cache_expires
ON platform_schema.app_cache(expires_at);
CREATE INDEX IF NOT EXISTS idx_app_cache_key_expires
ON platform_schema.app_cache(key, expires_at);
-- ==================== 2. 为AslScreeningTask添加新字段 ====================
-- 任务拆分支持字段
ALTER TABLE asl_schema.screening_tasks
ADD COLUMN IF NOT EXISTS total_batches INTEGER DEFAULT 1,
ADD COLUMN IF NOT EXISTS processed_batches INTEGER DEFAULT 0,
ADD COLUMN IF NOT EXISTS current_batch_index INTEGER DEFAULT 0;
-- 断点续传支持字段
ALTER TABLE asl_schema.screening_tasks
ADD COLUMN IF NOT EXISTS current_index INTEGER DEFAULT 0,
ADD COLUMN IF NOT EXISTS last_checkpoint TIMESTAMP,
ADD COLUMN IF NOT EXISTS checkpoint_data JSONB;
-- ==================== 3. 验证创建结果 ====================
-- 查看app_cache表结构
SELECT
column_name,
data_type,
is_nullable,
column_default
FROM information_schema.columns
WHERE table_schema = 'platform_schema'
AND table_name = 'app_cache'
ORDER BY ordinal_position;
-- 查看screening_tasks新增字段
SELECT
column_name,
data_type,
is_nullable,
column_default
FROM information_schema.columns
WHERE table_schema = 'asl_schema'
AND table_name = 'screening_tasks'
AND column_name IN (
'total_batches', 'processed_batches', 'current_batch_index',
'current_index', 'last_checkpoint', 'checkpoint_data'
)
ORDER BY ordinal_position;
-- ==================== 完成 ====================
-- ✅ 缓存表已创建
-- ✅ 任务拆分字段已添加
-- ✅ 断点续传字段已添加
