# 📑 Data Contracts — Stable Interfaces for RAG & Agents
Everything WFGY touches is JSON-first and versioned. These “contracts” make pipelines observable, reproducible, and easy to debug.

## 0) Envelope (required for all records)
```json
{
"schema_version": "1.0.0",
"event": "ingest.write | retrieve.run | rerank.run | answer.decide",
"ts": "2025-08-13T10:22:59Z",
"trace_id": "uuid",
"agent_id": "scout|medic|engineer|retriever|system",
"mem_rev": "r42",
"mem_hash": "sha256:..."
}
````
* `mem_rev`/`mem_hash` prevent **memory overwrite** and **desync**.
* Use the same envelope for logs and datasets.
---
## 1) Chunk record
**Purpose:** atomic, traceable text unit for retrieval.
```json
{
"$schema": "https://wfgy.dev/schemas/chunk-1.0.json",
"chunk_id": "c_00123",
"doc_id": "d_wfgy_paper",
"section_id": "s_intro",
"span": {"line_start": 120, "line_end": 154},
"lang": "en",
"text": "Delta-S measures semantic stress ...",
"hash": "sha256:...",
"embedding": {
"model": "sentence-transformers/all-MiniLM-L6-v2",
"dim": 384,
"vector": [0.012, -0.044, ...],
"normalized": true,
"metric": "cosine"
},
"anchors": ["ΔS", "semantic stress"]
}
```
**Rules**
* Keep **original text** + **normalized text** (case/punctuation) if you apply normalization downstream.
* Always store `metric` and `normalized`.
---
## 2) Query record
```json
{
"$schema": "https://wfgy.dev/schemas/query-1.0.json",
"q_id": "q_2025_08_13_0001",
"text": "How does ΔS detect retrieval failure?",
"lang": "en",
"hyde": "Generate a canonical query about ... (optional)",
"tokens": {"count": 12, "analyzer": "icu"},
"hints": {"doc_id": ["d_wfgy_paper"], "section_id": []}
}
```
---
## 3) Retrieval result (candidate)
```json
{
"$schema": "https://wfgy.dev/schemas/retrieved-1.0.json",
"q_id": "q_2025_08_13_0001",
"ranker": "dense|bm25|hybrid",
"k": 50,
"items": [
{
"chunk_id": "c_00123",
"doc_id": "d_wfgy_paper",
"score": 0.812, // retriever-native score
"cosine": 0.91, // optional explicit cosine
"ΔS_q_ctx": 0.36, // optional, if ground anchor available
"source": "dense",
"features": {"bm25": 8.3, "dense": 0.91}
}
]
}
```
---
## 4) Rerank result
```json
{
"$schema": "https://wfgy.dev/schemas/rerank-1.0.json",
"q_id": "q_2025_08_13_0001",
"model": "BAAI/bge-reranker-base",
"k_in": 60,
"k_out": 8,
"items": [
{
"chunk_id": "c_00123",
"pre_score": {"dense": 0.91, "bm25": 8.3},
"post_score": {"ce": 0.82},
"reason": "mentions ΔS definition and failure threshold",
"selected": true
}
]
}
```
---
## 5) Prompt frame (schema-locked)
```json
{
"$schema": "https://wfgy.dev/schemas/prompt-frame-1.0.json",
"system": "You are a grounded assistant. Cite before you explain.",
"task": "Answer the user's question using ONLY the cited snippets.",
"constraints": ["No cross-source merging", "Cite line spans"],
"citations": [
{"id": "c_00123", "doc_id": "d_wfgy_paper", "section_id": "s_intro", "span": [120,154]}
],
"question": "How does ΔS detect retrieval failure?"
}
```
---
## 6) Answer + trace
```json
{
"$schema": "https://wfgy.dev/schemas/answer-1.0.json",
"q_id": "q_2025_08_13_0001",
"answer_text": "ΔS measures the semantic gap ...",
"cited_chunks": ["c_00123", "c_00987"],
"λ_observe": "→",
"metrics": {"ΔS_q_ctx": 0.38, "latency_ms": 922}
}
```
---
## 7) Metrics pack (for CI)
```json
{
"$schema": "https://wfgy.dev/schemas/metrics-1.0.json",
"dataset": "goldset_v1",
"recall@50": 0.91,
"nDCG@10": 0.62,
"ΔS_mean": 0.41,
"ΔS_p95": 0.58,
"λ_convergent_rate": 0.82
}
```
---
## Acceptance checklist
* ✅ All records include **envelope** (schema\_version, event, ts, trace\_id, mem\_rev/hash).
* ✅ Chunks persist **metric** and **normalized** flags.
* ✅ Prompts are **schema-locked** (cite → explain).
* ✅ Answers store **cited chunk IDs** and **λ state**.
* ✅ Metrics committed per PR (goldset.jsonl).
