• The justification states xUnit “writes TRX result files”, but TRX output is produced by dotnet test when configured with the TRX logger (with the VS adapter installed), not by xUnit itself. Consider rewording to reflect that TRX generation comes from the test runner configuration (e.g., --logger trx) so the requirement text is technically accurate.

Fixed in cc5d7e2 — added <OutputType>Exe</OutputType> to the test project. All 45 tests pass (15 × net8.0/net9.0/net10.0).
