A governance fix page for when **data origin, transformation, and lineage** are unclear or unverifiable.  
Use this page when retrieval results cannot be traced back to their dataset source, or when provenance breaks across documents, chunks, embeddings, and answers.

---

## When to use this page
- Retrieval output has no clear link back to its document or section.  
- Embedding and chunk pipelines overwrite or drop provenance fields.  
- Audit trail is incomplete across ingestion, index, and RAG responses.  
- Approvals or waivers exist but cannot be joined to data versions.  
- Multi-hop pipelines lose lineage across systems (ETL, embedding, vectorstore, orchestration).  

---

## Acceptance targets
- Every retrieved snippet includes `{doc_id, section_id, source_url, offsets, revision}`.  
- Lineage fields survive across **document → chunk → embedding → retriever → LLM**.  
- Audit joins can reconstruct provenance end-to-end with ≥ 0.95 coverage.  
- ΔS(question, retrieved) ≤ 0.45 for governed outputs.  
- Waivers and overrides include expiry and accountable owner.

## Typical breakpoints and WFGY fix

- **Lost provenance in chunking**  
  → [chunking-checklist.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/chunking-checklist.md)  
  Ensure chunk metadata carries `doc_id`, `section_id`, and token offsets.

- **Vector store overwrites or strips lineage fields**  
  → [vectorstore-fragmentation.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/vectorstore-fragmentation.md)  
  Enforce schema contracts on ingestion and retrieval layers.

- **Answers cannot be tied back to original snippet**  
  → [retrieval-traceability.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/retrieval-traceability.md)  
  Require cite-then-explain and enforce snippet ID propagation.

- **Ambiguous approval or version skew**  
  → [bootstrap-ordering.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/bootstrap-ordering.md),  
  → [predeploy-collapse.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/predeploy-collapse.md)  

- **Multi-system lineage gaps (ETL, embedding, RAG orchestration)**  
  → [data-contracts.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/data-contracts.md)  
  Contract schema ensures interoperability across steps.  

---

## Minimal governance checklist
1. **Ingest contracts** — Every ETL pipeline attaches `doc_id`, `revision`, and `source_url`.  
2. **Chunk schema** — Ensure token offsets and section boundaries are immutable.  
3. **Embedding schema** — Carry `embedding_id`, `doc_hash`, and `index_hash`.  
4. **Retriever response** — Must include `snippet_id` + lineage fields, not just text.  
5. **LLM prompt contracts** — Require cite-then-explain, forbid unlinked spans.  
6. **Audit trail** — Every approval and waiver linked to specific dataset version.
