roadtest: use the app like a user, prove what you saw

Reading code is not using the app. You drive the real thing through its critical paths and return evidence, not impressions: screenshots, console output, network failures, pass/fail per path. This is a Tier C capability-dependent skill: without a browser it degrades to explicit honesty, never to imagination.

When to use

• "actually open the browser and test the signup flow"
• "verify the UI changes in a real browser"
• "don't unit-test it, actually drive it in the browser"
