Diagnostic toolkit
Select one evidence test. Each test consumes credits and time.
Root-cause hypothesis
Choose the most likely simulated cause before resolving.
Response actions
Every action changes quality, cost, downtime, risk, and long-term stability.

Prioritise, acknowledge, and suppress noisy warnings.
Incident timeline
Production drift playbook
Use a baseline that reflects expected production behaviour. Rolling baselines adapt quickly, while fixed baselines expose slow cumulative change. Seasonal baselines reduce false alerts when recurring demand patterns are expected.
Data drift changes feature distributions. Concept drift changes the relationship between features and outcomes. Delayed labels make concept drift harder to confirm, so combine proxy metrics, confidence trends, and segment analysis.
Prefer reversible actions during uncertainty. Shadow deployments, challenger tests, fallback models, and human review reduce operational risk. Retraining without fixing a broken pipeline often reproduces the incident.
Metric glossary
| PSI | Population Stability Index compares distribution buckets. |
|---|---|
| KS test | Measures distribution difference using the maximum cumulative gap. |
| JS divergence | A symmetric, bounded divergence between probability distributions. |
| Calibration | Checks whether predicted confidence matches observed frequency. |
| Training-serving skew | Production preprocessing differs from training preprocessing. |
| Residual drift | Prediction errors change over time or across segments. |
