Mouse Evidence Lab
Test browser-visible mouse clicks, holds, movement and wheel events. Review event timing locally and export JSON or CSV evidence for comparison.
How we build a check
This workbench processes supported inputs locally. We test calculations, file structure and generated artifacts using independent readers or known fixtures where available. The example runs the same processing path as a supplied input; it does not stand in for checking your own result.
