When evaluation metrics **swing unpredictably** across runs (precision, recall, ΔS, coverage) even though the data and index appear unchanged.
|
||
This signals **eval drift**: your evaluation harness is not structurally stable.

## Core acceptance
|
||
- ΔS(question, retrieved) ≤ 0.45 across 3 paraphrases
|
||
- Coverage ≥ 0.70 per target section
|
||
- λ convergent on 2 seeds, stable across runs
|
||
- Variance of metrics ≤ 0.05 across replays

## Typical symptoms → exact fix
|
||
|
||
| Symptom | Likely cause | Open this |
|
||
|---------|--------------|-----------|
|
||
| Precision/recall varies ±0.20 each run | eval harness non-deterministic | [Eval Precision/Recall](https://github.com/onestardao/WFGY/blob/main/ProblemMap/eval/eval_rag_precision_recall.md) |
|
||
| Identical queries give different metrics | bootstrap not fenced | [Bootstrap Ordering](https://github.com/onestardao/WFGY/blob/main/ProblemMap/bootstrap-ordering.md) |
|
||
| Eval metrics collapse on fresh deploy | index not fully warmed | [Predeploy Collapse](https://github.com/onestardao/WFGY/blob/main/ProblemMap/predeploy-collapse.md) |
|
||
| Coverage < 0.50 despite gold answers | embedding or chunk drift | [Embedding ≠ Semantic](https://github.com/onestardao/WFGY/blob/main/ProblemMap/embedding-vs-semantic.md), [Chunking Checklist](https://github.com/onestardao/WFGY/blob/main/ProblemMap/chunking-checklist.md) |

## Fix in 60 seconds
|
||
|
||
1. **Lock seeds**
|
||
Fix random seeds at retrieval, reranker, and eval harness layers.
|
||
|
||
2. **Fence bootstrap**
|
||
Require `VECTOR_READY==true` and index hash match before eval begins.
|
||
|
||
3. **Replay 3 paraphrases**
|
||
Eval the same question with 3 paraphrases. Require ΔS variance < 0.05.
|
||
|
||
4. **Cross-seed check**
|
||
Run two seeds. λ must remain convergent across both.
|
||
|
||
5. **Regression gate**
|
||
Ship only if coverage ≥ 0.70 and precision/recall stable within 0.05.

## Copy-paste eval harness snippet
|
||
|
||
```python
|
||
def eval_guardrails(question, retrieved, gold):
|
||
ds_qr = deltaS(question, retrieved)
|
||
ds_rg = deltaS(retrieved, gold)
|
||
|
||
assert ds_qr <= 0.45, "ΔS drift detected"
|
||
assert coverage(retrieved, gold) >= 0.70, "Coverage too low"
|
||
assert lambda_state(retrieved) in {"→","←","<>"} , "λ divergent"
|
||
|
||
return {
|
||
"ΔS_qr": ds_qr,
|
||
"ΔS_rg": ds_rg,
|
||
"coverage": coverage(retrieved, gold),
|
||
"λ": lambda_state(retrieved)
|
||
}
|
||
````
|
||
|
||

|
||
|
||
## Diagnostic probes
|
||
|
||
* **Re-run variance test**: run eval 5 times, log precision/recall. Stddev >0.05 → unstable harness.
|
||
* **Anchor comparison**: compare ΔS to gold anchor vs decoy. If both similar, re-embed.
|
||
* **Deploy warm-up**: log `VECTOR_READY` and index hash before eval.
