summary
SIG Storage maintains core APIs and is shipping concrete changes: auto-remove PVCs from StatefulSets is graduated, recovery-from-resize-failure has reached beta, and volume group snapshots are available as a beta API. Roadmap items target 1.33: Portworx CSI migration GA in 1.33, always-honor PV reclaim policy GA, COSI and mutable CSI node-allocatable as alphas, and storage-capacity scoring alpha. Git-repo in-tree driver is being removed (errors in 1.33, kubelet gate until 1.36, code dropped by 1.39). Community has ~25–30 meeting attendees, ~30 approvers, and a csi-hostpath example driver.
