inference route canaries now include policy drift checks

Teams are extending canary analysis with policy-drift checks so route changes are validated for control behavior as well as latency and quality (Kubernetes progressive delivery).

canary evolution

Route canaries now compare refusal rates, entitlement outcomes, and policy-version alignment across baseline and candidate paths.

engineering signal

• Governance regressions surface earlier in rollout.
• Rollback decisions become less subjective.
• Policy observability quality becomes release-critical.

my take

Canaries are finally testing what matters in AI production, not only speed.
