Hey! Thanks for adding error resilience tests for the RepoPerformanceTable. Ensuring the fallback UI renders correctly when the repo performance array is empty or encounters an error is vital for exception safety.

I'm assigning level:intermediate, type:testing, and quality:clean.

Everything looks great, approving!
