Direction seems good.
I’d like to think it through and give some more detailed feedback on some of the specifics, but here are some immediate thoughts.
I don’t understand why we need the ":" or "+" separators. Why not just a list of space-separated words and URLs that can be a mix of modifiers and outcomes? I don’t think we need to support the same words for both modifiers and outcomes. If we want to enforce some kind of order, that would be OK, to reduce arbitrary differences.
Instead of bug_ojan I’d prefer a format more like bug(ojan). I’d like to see a list of the modifier and outcome words so I can easily review them.
Maybe the test specifier (name or directory name) should come first, before the modifiers and outcomes.
