# Evidence: rag-chunk-evidence-identity-dedup
|
|
|
|
## 代码证据（变更前）
|
|
|
|
- `KnowledgeEvidencePostProcessor.sourceKey` 使用 source/title 去重
|
|
- `RagResultProjector` 用 source 回退 document_id 并 HashSet 去重
|
|
- 写入路径 metadata 已有 docId/chunkIndex，读路径未一等化
|
|
|
|
## 规格证据
|
|
|
|
- 旧 `openspec/specs/rag-knowledge-retrieval` 要求 source 级 dedup（本 change 以 delta 修正）
|
|
- `docs/milvus-hybrid-search-integration-checklist.md` §1.1 定义 Delivery 1 地基
|
|
|
|
## 验证证据
|
|
|
|
- 单测覆盖 multi-chunk keep / true-dup merge / maxChunksPerDocument / projector same-source multi-chunk
