Here's a little chunk about investigations that I wrote 3 years ago (according the date on the Google doc, at least). The clue hierarchy idea in particular might fit in with what you're developing. The basic idea is that the players get the core information they need, but good die rolls can make solving the mystery easier/faster by filling in gaps between player and character ability, perception, and world knowledge. The specific mechanics are from some previous version of the system I've been in tinkering with for several years, so I don't even know the exact context for them, but they fit the basic "a good roll is good" paradigm. https://docs.google.com/document/d/1chwyhetKuKz5sLDquxRQ5h7SkEqWjgmc-gsLPEaGZ3w/edit?usp=sharing
