Release: Blue-green / canary deploy with automated rollback on SLO regression

[joelpeace48-cell]

Context

Deploys (helm/k8s referenced) need a safe rollout: canary a fraction of traffic, watch SLOs, and
auto-rollback on regression — for both backend and contract upgrades.

Scope

• Blue-green or canary rollout for the backend with automated health/SLO gating.
• For contracts: staged upgrade (timelock + canary verification) tied to the upgrade allowlist.
• One-command rollback runbook; rollback tested.

Acceptance criteria

• A bad deploy is auto-detected and rolled back without manual intervention.

Verification

• Canary with an injected error-rate regression triggers automatic rollback.
