Traffic split

Sending only a **fraction of requests** to a new version while the rest stay on stable — core of canary and A/B deploys.

#When to use

Model, prompt, or index rollouts where blast radius must stay small.

Zero-traffic staging only — you need real requests to compare metrics.

90% → v1, 10% → v2 for 24h; promote if error rate and latency match baseline.
