Progressive rollout

Canary steps, dwell time, signal gating and automatic rollback.

rollout:
  strategy: canary
  steps: [5, 25, 50, 100]
  dwell: 4m
  gate:
    p95_latency: < 200ms
    error_rate: < 0.5%

Dwell time

Dwell time should be long enough for the gate signals to be statistically meaningful at that traffic share. On low-traffic services, increase it.

The previous release is kept warm for the duration of the rollout. Rollback shifts traffic back to it rather than re-running the pipeline.
