# Eval Observability — Regression Gate
|
||
|
||
A structural safeguard that enforces measurable thresholds before any pipeline is promoted to production.
|
||
Use this page to define hard acceptance criteria (ΔS, coverage, λ, resonance) and stop silent regressions from shipping.
|
||
|
||
---
|
||
|
||
## Why regression gates matter
|
||
|
||
- **Catch semantic drift early**: A small rise in ΔS leads to compounding hallucinations downstream.
|
||
- **Stable releases**: Prevents model upgrades or retraining from silently reducing accuracy.
|
||
- **Auditable rules**: Clear thresholds mean every team member can verify before deploy.
|
||
- **Cross-stack consistency**: Same rules apply across providers, retrievers, and orchestration layers.
|
||

||
|
||
## Core gate thresholds
|
||
|
||
| Metric | Requirement | Failure signal |
|
||
|--------|-------------|----------------|
|
||
| ΔS(question, retrieved) | ≤ 0.45 | drift ≥ 0.60 means block release |
|
||
| Coverage of target section | ≥ 0.70 | low coverage = missing context |
|
||
| λ_observe | Convergent across 3 paraphrases, 2 seeds | divergence = unstable reasoning |
|
||
| E_resonance | Flat on 50–100 step windows | spikes = entropy collapse risk |
|
||
|
||
---
|
||
|
||
## Deployment checklist
|
||
|
||
1. **Pre-release batch eval**
|
||
Run gold set of ~100–500 Q&A pairs. Collect ΔS, coverage, λ, resonance.
|
||
|
||
2. **Gate decision**
|
||
- If ΔS ≤ 0.45 AND coverage ≥ 0.70 → **pass**.
|
||
- If ΔS between 0.46–0.59 → **manual review**.
|
||
- If ΔS ≥ 0.60 OR coverage < 0.70 → **fail, block release**.
|
||
|
||
3. **Variance probe**
|
||
Check λ stability across 3 paraphrases × 2 seeds. Divergence disqualifies release.
|
||
|
||
4. **Regression log**
|
||
Store results with index hash + commit hash + retriever config.
|
||
Enables reproducibility and rollback.
|
||

|
||
## Example gating script (pseudo)
|
||
|
||
```yaml
|
||
# regression_gate.yml
|
||
metrics:
|
||
deltaS: <=0.45
|
||
coverage: >=0.70
|
||
lambda: convergent
|
||
resonance: flat
|
||
goldset: eval_set_500.json
|
||
policy:
|
||
fail_on_drift: true
|
||
manual_review_range: [0.46, 0.59]
|
||
require_seeds: 2
|
||
require_paraphrases: 3
|
||
````

|
||
|
||
## Common pitfalls
|
||
|
||
* **Changing retriever k** without updating gates. Always re-test thresholds.
|
||
* **Skipping paraphrase probes**. One stable query is not enough.
|
||
* **Not logging coverage**. ΔS alone cannot prove retrieval completeness.
|
||
* **Silent config drift**. Gate must bind to exact retriever + index hash.
