# Acceptance: rag-chunk-evidence-identity-dedup

## 实现结果

Delivery 1 completed:

- chunk identity fields on candidates/evidence blocks
- `KnowledgeSearchPort` + dense adapter
- evidenceKey dedup + maxChunksPerDocument + return-n
- retrieve-k on lookup tool
- projector keeps same-source distinct chunks; `document_id` is chunk-scoped

## 验证

### 脚本验证

```text
mvn -q "-Dtest=LookupKnowledgeToolTest,KnowledgeEvidencePostProcessorTest,RagResultProjectorTest" test
```

结果：通过（exit 0）

### 静态验证

- Search/port wiring reviewed against OpenSpec tasks
- No new legacy SDK dependency added

### 浏览器/人工验证

未运行（纯检索契约变更，无 UI）

### 未验证

- 全量 harness E2E / 真实 Milvus 联调（Delivery 2 前可补）
- 生产配置默认 retrieve-k/return-n 调优

## 归档状态

- OpenSpec change ready to archive
- User pre-authorized archive for sm-flow staged delivery

## 后续

- Delivery 2: milvus hybrid search (separate change)
