+# Reranker Sanity Checklist
+
+Scope: validate a hybrid pipeline where BM25 and ANN feed a deterministic reranker.
+
+---
+
+## Pre checks
+
+- [ ] Persist BM25 and ANN candidate lists before reranking.
+- [ ] Fix a random seed and record model version for the reranker.
+- [ ] Store per-candidate features needed by the reranker.
+- [ ] Ensure identical tokenization between HyDE prompt and server.

+[Query parsing split](https://github.com/onestardao/WFGY/blob/main/ProblemMap/patterns/pattern_query_parsing_split.md)
+
+---
+
+## Baseline health
+
+- [ ] BM25 top k recall on the gold set ≥ 0.60 at k = 50.
+- [ ] ANN top k recall on the gold set ≥ 0.60 at k = 50.
+- [ ] Overlap Jaccard(BM25, ANN) logged for k = 50 to detect split.
+
+If overlap < 0.20 and both recalls are good, a query split is likely.  
+Route using the split detector or run two paths then merge.
+
+---
+
+## Reranker behavior
+
+- [ ] Uplift over the better baseline ≥ 5 percent recall at k = 10.
+- [ ] Ranking stable across 3 paraphrases. Kendall tau ≥ 0.60.
+- [ ] Tie breaking rule fixed and documented.
+- [ ] Deterministic output given the same candidates and seed.
+
+---
+
+## Acceptance targets
+
+- Coverage ≥ 0.70 on the gold set after reranking at k = 10 or 20.
+- ΔS(question, top1) ≤ 0.45 for at least 70 percent of queries.
+- λ_observe convergent across 3 paraphrases and 2 seeds.
+
+---
+
+## Debug sequence
+
+1. Log both candidate lists and measure overlap.  
+2. If split detected, enable the split route or increase k per branch.  
+3. Try a simpler deterministic reranker first.  
+4. Re-measure uplift and stability.
