October 2025 — Rancher Docs: Implemented a targeted Pod Security Admission (PSA) exemption to enable Supportability Review workflows. A focused change in rancher/rancher-docs exempts the sr-operator-system namespace from PSA restrictions, allowing Supportability Review pods to start and run reliably within Rancher environments. The change was implemented via a single commit and validated to prevent disruption to other PSA-scoped operations, demonstrating careful scope control and adherence to security posture.
