Applied in this branch via commits 5146465 and 612ab13. The executor failure path now preserves and reports the original error, and the local dataStore typo is corrected.

@copilot Fix the test cases that are failing

I checked the failing run and re-ran tests on this branch: go test ./... passes locally, and current GO-Flow-Build runs on code_cleanup are successful. The only failing historical run was due to deprecated actions/upload-artifact@v1, already fixed in ea5720b. If you’re seeing a different failing test/job, share that run link and I’ll fix it.
