This is dogfooding as code. It spins up a browser, walks your app like an actual user (typing, clicking, watching console), and won't let you skip interactions or fake timestamps. Hard gates on console errors, 5xx responses, layout collapse, and accessibility violations mean no wiggle room on the stuff that breaks production. The interaction manifest tracks every click with timestamps, and there's an audit-the-audit meta-check that rejects rushed reports where timings look implausible. Runs eleven stress scenarios, tests responsive breakpoints, and produces a ranked findings list with reproduction steps. Use it before deploy when you need confidence that real usage patterns won't explode, not just that the DOM looks okay in a static pass.
