## Applied — 2026-10-21
Applied with the workstation kubeconfig under the founder's wave-1 authorization (the-custodian docs/decisions/2026-10-21-cust-wp-0071-delivery-interview.md), using the output of the railiance-cluster renderer at 3b18b84.
- HPA max is now 3/2/3, min 1.
- All six deployments request 10m CPU and are Ready 1/1.
- Kourier is still ClusterIP, and the rapp-qonto Knative service is Ready.
- Node CPU requests fell from 3605m to 3445m (−160m), as planned.
The cluster policy `reject-secret-last-applied` refused the Knative webhook certificate object in the render. Knative generates its contents at runtime, so it stayed unchanged; the fix is RCLUSTER-WP-0020-T04. Evidence: the-custodian docs/evidence/2026-10-21-wave1-apply.md.
