Big step forward - looks like group-based rules triggering is not implicated here.
My suspicions are back on DSL’s handling of a large number of string constants.
Well, if one is getting mired down doing whatever there would be a lot of pot luck involved about it holding up parts of the other’s processing, so we must do both experiments.
You’re not, you are choosing to name your new logger Rules.Experiments (and not unreasonably so, in the circumstances)
