📝 WalkthroughWalkthroughThe PR adds global logger and rsync-image handling to the transfer-PVC command. It validates cloud-storage options and expands tests for validation, PVC construction, transfer options, resource resolution, cleanup, garbage collection, and resource naming. ChangesTransfer-PVC command validation and wiring
Estimated code review effort: 3 (Moderate) | ~25 minutes Merge Risk: 🟠 High · up to The PR still permits failed rsync operations to be reported as successful, which can cause downstream workflows to use incomplete PVC data, and indirect transfers retain cloud data by default despite the cleanup option. These current behaviors create high-impact merge-readiness risks that should be addressed before merging. Suggested reviewers: 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

195-199: 🔒 Security & Privacy | 🟠 Major | 🏗️ Heavy liftDo not claim cloud cleanup before it exists.
The indirect-transfer path skips cloud cleanup when
KeepCloudDatais false. The default path therefore retains transferred data even though--keep-cloud-datasays it controls that retention.Implement cloud-data deletion before exposing this flag, or reject indirect transfers until cleanup is available. Retained PVC data can create a privacy exposure and ongoing storage cost.

so assigning the default endpointNginx type persists for callers. Add a
regression case with an empty Type and valid Subdomain that expects validation
to succeed and Type to equal endpointNginx, while retaining the existing
