What it shows

  • Ingress mirrors live traffic asynchronously to candidate models.
  • Responses return exclusively from baseline; shadow errors are ignored.
  • Evaluator diffs accuracy and latency metrics offline without user impact.

The takeaway

Shadow deployments reveal latency spikes and production distribution drift with zero user blast radius.
