I am using the forensics-api-plugin as part of the coverage-plugin for getting diffs. To determine the reference build, I call

discoverReferenceBuild()

in my pipeline.

Doing so revealed that sometimes I would not get diffs. The reason seems to be that coverage can be disabled on a per-build basis in my case, thus the reference build sometimes does not contain any coverage data.

For this reason, I would like to see support for some reference build filtering options, especially by action class and action ID.
