I want to be able to see all projects that answer similar questions (superprojects)

This could be a way for groups to loosely collaborate. All evidence could be viewable in a single superproject. It could show disagreements between different approaches but the methods for creating all evidence will be exactly traceable. Should probably have some way to rank likelihood of being true in cases where low quality research makes it into the superproject.

The issue names no files, tests, or entry points. Start by defining how projects and evidence should be combined, including disagreement visibility, traceability, and likelihood ranking; the work is done when those behaviors have concrete acceptance criteria and an agreed implementation scope.
