🩺 Stability & Availability | 🟠 Major | ⚡ Quick win
Make the fallback shell step fail when git diff fails.
The script has no set -e. The step exit code comes from base64, which succeeds even when git diff fails or writes nothing. In that case the step returns empty output, fields is empty, and changedFiles is empty.
The result is a silent empty changed-file list instead of an error. getMergeRequestChangedFileList then caches [] without marking the build unstable, because no exception is thrown. Downstream consumers such as getMultiGpuFileChanged and getCbtsResult see zero changed files and narrow test selection.
Add set -euo pipefail so a git diff failure propagates to the Groovy caller and reaches the fallback error handling.
🐛 Proposed fix
def encodedNameStatus = pipeline.sh(
script: """
+ set -euo pipefail
name_status_file=\$(mktemp)
trap 'rm -f "\${name_status_file}"' EXIT
git -C ${LLM_ROOT} diff --name-status --find-renames -z ${baseCommit} ${headCommit} > "\${name_status_file}"
base64 < "\${name_status_file}"
""",
returnStdout: true
).readLines().join()📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Background
GitHub PR changed-file API failures currently prevent waive-list merging and make changed-file based CI selection fall back at the caller level.
Summary
Impact
The normal GitHub API path is unchanged. The internal mirror is accessed only after a GitHub PR files API exception. CBTS fallback computes patches only for files selected for content-level analysis.
Testing
Dev Engineer Review
jenkins/L0_MergeRequest.groovyadds an internal Git mirror fallback after GitHub PR files API exceptions. The fallback validates the wrapper build number and 40-character head commit, parses NUL-delimited Git output, supports changed-file lists and patches, and reports malformed records. GitLab behavior, GitHub success behavior, and caller-specific final fallbacks remain unchanged.Verify mirror ref availability, rename and deletion handling, API-to-Git parity, error classification, and CBTS filtering. Confirm that missing patches correctly become empty strings.
QA Engineer Review
No test changes.
Per-File QA Perspective
jenkins/L0_MergeRequest.groovy: Verify GitHub API behavior, mirror fallback activation, ref and commit validation, malformed-record handling, changed-file lists, waiver patches, CBTS patches, rename and deletion handling, and empty missing patches. Verify that GitLab and existing caller-specific fallback behavior remain unchanged.
