Kura 0.7.3

Kura 0.7.3 improves remote cache reliability for Bazel-size workloads and makes Kubernetes storage expansion safer.

Remote cache

• ByteStream-uploaded CAS blobs are now stored under the same blob/{hash}/{size} key as digest-based operations. REAPI clients such as Bazel can finally find large uploaded blobs during FindMissingBlobs, so cache hits for large outputs are trusted instead of discarded and re-executed.
• Blobs written by earlier versions sit under the old key and will age out naturally as segments evict.

Kubernetes storage

• The Kura controller now expands persistent storage by patching live PVCs directly rather than mutating StatefulSet volumeClaimTemplates. You can grow storage to 200 Gi without deleting StatefulSets or orphaning volumes.
• The controller refuses to shrink PVCs when the requested size is smaller than the current allocation.
• The standalone Helm chart default persistence is now 200 Gi, matching the controller default.
