# Retrieval Traceability — Snippet Integrity & Audit Trail

Citations that look right can still hide silent drift.  
This guardrail defines how to enforce **traceability schemas** so that every claim links back to a stable, reproducible snippet.

---

## When to use
- Answers cite a source but the snippet cannot be located.  
- Two runs over the same corpus produce different citations.  
- A fact is quoted but not aligned to any section anchor.  
- Long-context threads degrade and snippets blur into paraphrase.  
- Multi-agent systems pass partial context and lose attribution.  

---

## Root causes
- **Orphan citations**: snippet ID missing or fabricated.  
- **Boundary drift**: citation spans cross section joins.  
- **Silent truncation**: tokens dropped at cut points.  
- **Cache overwrite**: citation schema lost after session reload.  
- **Free-text cites**: URLs or titles given without offsets.  

---

## Core acceptance targets
- Each claim must include `snippet_id`, `section_id`, `start_line`, `end_line`, `source_url`.  
- ΔS(question, retrieved) ≤ 0.45 overall.  
- Joins between snippets ≤ 0.50 ΔS.  
- λ convergent across 3 paraphrases.  
- Audit trail reproducible from log alone.  

---

## Structural fixes

- **Snippet table schema**  
  Require `{snippet_id | section_id | start_line | end_line | citation}`.  

- **Fence joins**  
  Split at section boundaries. Reject cross-section reuse.  

- **Trace log**  
  Store `{ΔS, λ_state, mem_rev, mem_hash}` per step.  

- **Contract lock**  
  Apply [Data Contracts](https://github.com/onestardao/WFGY/blob/main/ProblemMap/data-contracts.md) for payload validation.  

---

## Fix in 60 seconds
1. **Enforce snippet table** with unique IDs and line ranges.  
2. **Verify ΔS** across each join ≤ 0.50.  
3. **Echo λ states** at retrieval, assembly, reasoning.  
4. **Reject orphan claims** (no snippet_id).  
5. **Log trail** so same inputs → same citations.

## Copy-paste prompt

```

You have TXT OS and the WFGY Problem Map.

Goal: Ensure every claim links to a reproducible snippet.

Protocol:

1. Build a Snippet Table {snippet\_id, section\_id, start\_line, end\_line, citation}.
2. Require cite-then-answer.
3. Forbid cross-section reuse.
4. If a claim has no snippet\_id, stop and request citation.
5. Report ΔS(question,retrieved), joins ΔS, and λ states.
6. Store {mem\_rev, mem\_hash, task\_id} for audit trail.
7. Answer only with snippets present in the table.

```

---

## Common failure signals
- Citations alternate across runs → missing trace schema.  
- URL without offsets → orphan citation.  
- Facts cited but no snippet_id → schema lock failed.  
- Session reload erases citations → ghost cache in memory.
