# 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)
