# Eval Observability — Global Fix Map

This folder provides **guardrails for evaluation and observability** in RAG and agent pipelines.  
It shows how to catch silent drift, regressions, and unstable metrics before they break your system.

---

## What this folder is
- A starter kit to make evals predictable and repeatable.
- Guardrails for metrics, variance, and drift detection.
- Copy-paste probes and configs you can add to your pipeline.
- Acceptance targets you can actually measure and enforce.

---

## When to use
- Metrics look **unstable** between runs.  
- Coverage seems high but answers still drift.  
- ΔS changes across paraphrases or seeds.  
- λ flips divergent after harmless edits.  
- Benchmarks regress without any code change.  
- Long-run evals show a slow decline.

---

## Acceptance targets
- **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 seeds  
- **No downward drift** beyond 3 eval windows  
- **E_resonance stays flat** on long evals

## 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

## FAQ

**Q: What if my metrics vary a lot each run?**
A: Check [variance\_and\_drift.md](./variance_and_drift.md). Add more seeds and enforce variance ≤0.15.

**Q: My eval passes locally but fails in CI — why?**
A: See [metrics\_and\_logging.md](./metrics_and_logging.md). Local runs often miss logging detail. CI must enforce the same eval contract.

**Q: What if coverage is high but the answer is still wrong?**
A: Open [coverage\_tracking.md](./coverage_tracking.md). You might be measuring snippet recall, not semantic coverage. Switch to ΔS-based coverage.

**Q: ΔS is always drifting, even on simple questions.**
A: Look at [deltaS\_thresholds.md](./deltaS_thresholds.md). Adjust thresholds and clamp variance with λ probes.

**Q: How do I stop regressions before release?**
A: Use [regression\_gate.md](./regression_gate.md). It defines pass/fail rules so bad models never ship.
