Incorrect reporting of called pipeline - done and successful false positives

- sometimes the caller pipeline reports that the called pipeline is done when it is not.
- sometimes the caller pipeline reports that the called pipeline is successful when it is not.

No files, tests, or specific entry points are identified in the issue. Start by tracing how the caller and called pipelines report completion and success, then reproduce the false-positive states; done means the caller reports both statuses accurately.
