The matrix is only as good as the operational experience behind it. If you've worked through a process upset and know the diagnostic path — what you checked, what the cause turned out to be, what actually fixed it — that's exactly what this tool needs.
Open a GitHub Issue to suggest diagnostic paths, common failure modes, or zones that should be prioritized. You don't need to know how to code — describe the symptom, the causes you've seen, and the corrective actions that worked.
