Greptile Summary

This PR migrates the premerge CI pipeline away from a Persistent Volume Claim (PVC) for inter-stage workspace sharing, relying instead on Jenkins' stash/unstash mechanism (already in use for the source_tree stash) and Artifactory uploads for persisting failure diagnostics.

• Removes the PVC credential and workspaceVolume persistentVolumeClaimWorkspaceVolume directives from both the Docker-build and GPU-test Kubernetes agents.
• Adds unstash "source_tree" at the start of the Premerge Test stage so the checked-out repository is available without the shared PVC workspace.
• Wraps the test execution in a try/catch that calls common.uploadDebugBundle on failure before rethrowing the exception, providing persistent failure artifacts via Artifactory.

Confidence Score: 4/5

The change is safe to merge; the stash/unstash swap for PVC is straightforward and test.sh does not rely on git history, so the default stash exclusions are harmless.

The migration from PVC to stash/unstash is mechanically correct, and the debug-bundle upload on failure is a useful addition. The one concern is that if uploadDebugBundle throws, it silences the original test failure exception rather than chaining errors, which could obscure root causes during debugging — but this is a non-blocking quality issue.

ci/Jenkinsfile.premerge — specifically the catch block around the debug bundle upload.

Important Files Changed

Filename	Overview
ci/Jenkinsfile.premerge	Removes PVC credential and workspaceVolume from both pipeline stages; replaces shared-filesystem approach with stash/unstash for the test stage and adds a try/catch to upload a debug bundle on failure.
