# Retrieval Readiness Checklist

Purpose: confirm the pipeline is safe to run before any evaluation or go-live.  
Applies to BM25, ANN, or hybrid stacks. Store agnostic.

---

## Inputs are consistent

- [ ] One embedding model per field, recorded in config.
- [ ] Normalization rule set and saved with the index (L2 or cosine compatible).
- [ ] Analyzer or tokenizer identical on write and read paths.
- [ ] Stopword set and stemming rules fixed and versioned.

---

## Index and data state

- [ ] `INDEX_HASH` matches the current code revision that produced vectors.
- [ ] Document count, chunk count, and vector count agree within 0.5 percent.
- [ ] Ingestion job reported zero empty payloads and zero parser errors.
- [ ] Cold caches warmed with ten representative queries.

---

## Gold set and probes

- [ ] Ten to fifty QA pairs with ground truth anchors prepared.
- [ ] Each QA pair has at least one resolvable `section_id` and `source_url`.
- [ ] ΔS probes ready for three paraphrases and two seeds.

---

## Acceptance targets

- ΔS(question, retrieved) ≤ 0.45  
- Coverage of the target section ≥ 0.70  
- λ_observe convergent across 3 paraphrases and 2 seeds  
- E_resonance stable on long windows

---

## Quick probe you can paste

```txt
I loaded TXT OS and WFGY pages.

Task:
- For question "Q", log ΔS(Q, retrieved) and λ across 3 paraphrases and 2 seeds.
- Enforce cite then explain with the traceability schema.
- If ΔS ≥ 0.60, return the smallest structural fix to reach ΔS ≤ 0.45 and coverage ≥ 0.70.

Return JSON:
{ "citations": [...], "ΔS": 0.xx, "λ_state": "<>", "coverage": 0.xx, "next_fix": "..." }

## Common fails and minimal fixes

* Mixed metrics or analyzers after deploy
  Fix: rebuild with a single metric and analyzer.
  See [Retrieval playbook](https://github.com/onestardao/WFGY/blob/main/ProblemMap/retrieval-playbook.md)

* Fragmented store, anchors missing
  Fix: re-chunk with anchor tests.
