# Data Contracts — Enforcing Snippet Schema & Payload Integrity

RAG and long-context reasoning collapse quickly if payloads drift.  
**Data Contracts** define the minimal schema that every retrieval, citation, and reasoning step must satisfy to remain auditable and reproducible.

---

## When to use
- Citations appear but fields like `snippet_id` or `section_id` are missing.  
- JSON payloads change shape across runs.  
- Downstream agents receive free-text with no schema lock.  
- Long-context sessions silently lose attribution or overwrite fields.  
- Multi-agent handoffs mutate keys or flatten nested fields.  

---

## Root causes
- **Loose schemas**: free-form JSON without validation.  
- **Field drift**: different casing, missing offsets, or swapped names.  
- **Silent truncation**: long answers cut JSON blocks.  
- **Inconsistent contracts**: each component defines its own schema.  
- **Opaque citations**: only plain text without structured trace.  

---

## Core acceptance targets
- Every snippet payload must include:  
  `{snippet_id, section_id, start_line, end_line, source_url, offsets, tokens}`  
- Coverage ≥ 0.70 for the target section.  
- ΔS(question, retrieved) ≤ 0.45.  
- λ convergent across 3 paraphrases.  
- Contracts must validate under the same schema across sessions.  

---

## Structural fixes

- **Schema lock**  
  Define a JSON schema for citations and enforce validation at ingestion.  

- **Contract inheritance**  
  Pass the same schema downstream to every agent and reasoning step.  

- **Casing & normalization**  
  Enforce consistent field names and Unicode normalization.  

- **Fail fast**  
  If schema validation fails, block reasoning and return fix instructions.

## Fix in 60 seconds
1. Define contract:  
   ```json
   {
     "snippet_id": "string",
     "section_id": "string",
     "start_line": "int",
     "end_line": "int",
     "source_url": "string",
     "offsets": [int],
     "tokens": [string]
   }
````

2. Validate every retrieval step against the contract.
3. Store the validated payload in the trace log.
4. Require cite-then-answer. Reject orphan claims.
5. Report ΔS and λ for each reasoning step.

## Copy-paste prompt

```
You have TXT OS and the WFGY Problem Map.

Task: enforce Data Contracts for retrieval and citation.

Protocol:
1. Validate that each snippet includes {snippet_id, section_id, start_line, end_line, source_url}.  
2. Reject orphans: if missing fields, stop and return fix tip.  
3. Require cite-then-answer.  
4. Log {ΔS(question,retrieved), λ_state, mem_rev, mem_hash}.  
5. Answer only with citations that pass contract validation.
```

---

## Common failure signals

* Citations alternate across runs → contract not enforced.
* JSON mode fails in provider → schema too loose.
* Free-text answers with no snippet\_id → orphan claims.
* Multi-agent pipelines mutate payloads → inconsistent contracts.
