replay aware canary analysis compares policy outcomes

Canary pipelines are replaying representative traffic and comparing policy decisions between baseline and candidate builds to detect non-obvious governance drift (Kubernetes deployment docs).

analysis flow

Systems now score canaries on policy-consistency deltas alongside latency and error budgets.

reliability signal

• Control regressions surface before broad exposure.
• Rollout gates gain stronger decision evidence.
• Teams reduce post-launch policy surprises.

my take

Replay-aware canaries are turning rollout risk into measurable policy behavior.
