|
||
|
||
A compact playbook to **stabilize evaluation** and ensure results are reproducible.
|
||
Use this when metrics look inconsistent, coverage drifts, or benchmarks feel untrustworthy.
|
||
|
||
---
|
||
|
||
## Core acceptance
|
||
|
||
- **ΔS(question, retrieved) ≤ 0.45**
|
||
- **Coverage ≥ 0.70** to target section
|
||
- **λ remains convergent** across 3 paraphrases and 2 seeds
|
||
- **Variance ratio ≤ 0.15** across seed runs
|
||
- **No monotonic downward drift** beyond 3 windows
|
||
|
||
---
|
||
|
||
## Step 1 — Regression Gate
|
||
|
||
Run a gate before promoting new models or retrievers.
|
||
- Require ΔS ≤ 0.45 and coverage ≥ 0.70 on 3 paraphrases.
|
||
- Block deploy if λ flips divergent.
|
||
Open: [regression_gate.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/GlobalFixMap/Eval_Observability/regression_gate.md)
|
||
|
||
---
|
||
|
||
## Step 2 — Alerting and Probes
|
||
|
||
Set live probes to catch collapse early.
|
||
- Alert when ΔS ≥ 0.60 or λ flips.
|
||
- Emit logs for coverage gaps, drift slopes, entropy rises.
|
||
Open: [alerting_and_probes.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/GlobalFixMap/Eval_Observability/alerting_and_probes.md)
|
||
|
||
---
|
||
|
||
## Step 3 — Coverage Tracking
|
||
|
||
Measure **retrieved vs target section** alignment.
|
||
- At least 70% coverage on gold targets.
|
||
- Track section-level recall, not just overall hit-rate.
|
||
Open: [coverage_tracking.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/GlobalFixMap/Eval_Observability/coverage_tracking.md)
|
||
|
||
---
|
||
|
||
## Step 4 — ΔS Thresholds
|
||
|
||
Normalize ΔS scoring and enforce thresholds.
|
||
- Stable < 0.40
|
||
- Transitional 0.40–0.60
|
||
- Collapse ≥ 0.60
|
||
Open: [deltaS_thresholds.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/GlobalFixMap/Eval_Observability/deltaS_thresholds.md)
|
||
|
||
---
|
||
|
||
## Step 5 — λ Observe
|
||
|
||
Use λ probes to detect schema drift.
|
||
- Run same query across seeds and paraphrases.
|
||
- If λ flips, lock schema and enforce reranker.
|
||
Open: [lambda_observe.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/GlobalFixMap/Eval_Observability/lambda_observe.md)
|
||
|
||
---
|
||
|
||
## Step 6 — Variance and Drift
|
||
|
||
Log variance ratios and detect slow regressions.
|
||
- Variance ratio ≤ 0.15
|
||
- Drift slope ≤ 0.02 per batch
|
||
- Alert if monotonic decline lasts 3+ windows
|
||
Open: [variance_and_drift.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/GlobalFixMap/Eval_Observability/variance_and_drift.md)
|
||
|
||
---
|
||
|
||
## Step 7 — Audit & Escalation
|
||
|
||
If instability remains:
|
||
- Rebuild embeddings with [embedding-vs-semantic.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/embedding-vs-semantic.md)
|
||
- Patch retriever fragmentation with [vectorstore-fragmentation.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/vectorstore-fragmentation.md)
|
||
- Apply reranking schema: [rerankers.md](https://github.com/onestardao/WFGY/blob/main/ProblemMap/rerankers.md)

## Copy-paste eval contract
|
||
|
||
```yaml
|
||
eval_contract:
|
||
seeds: 3
|
||
paraphrases: 3
|
||
targets:
|
||
deltaS: <=0.45
|
||
coverage: >=0.70
|
||
lambda: convergent
|
||
variance: <=0.15
|
||
drift: <=0.02
|
||
alerts:
|
||
- deltaS >=0.60
|
||
- lambda divergent
|
||
- drift slope >0.02
