- 控制器与接口 DTO

这些能力继续留在业务工程，由业务层依赖 `easy-agents-rag` 提供的能力完成编排。
其中 OCR / PDF 解析能力改由独立的 `easy-agents-document` 能力域承接，不再归属 `easy-agents-rag`。
## 后续演进
后续演进顺序建议如下：
1. 完成 `rag-ingestion` 首批能力迁移并稳定对外接口
2. 补充 `rag-ocr`，接入 OCR 与版面恢复
3. 补充 `rag-enhance`，支持图增强、RAPTOR、索引增强
4. 补充 `rag-retrieval`，统一查询增强与召回后处理
2. 补充 `rag-enhance`，支持图增强、RAPTOR、索引增强
3. 补充 `rag-retrieval`，统一查询增强与召回后处理
整体原则：
- `easy-agents-core` 保持基础抽象
- `easy-agents-rag` 聚合 RAG 领域实现
- `easy-agents-document` 承接 OCR、版面理解与 PDF 解析等文档处理能力
- 业务工程只保留编排、持久化与产品层逻辑
