Ten Rules, One Broken Flow
Tag the flow's ten sins before the timer runs out.
the cross-learner heatmap is the twist — it shows which violation everyone misses, revealing that certain usability sins are systematically invisible to trained eyes, not just yours
What goes in, what comes out
Learner click-throughs a deliberately flawed multi-step flow — checkout, signup, or settings — and races a timer tagging violations by clicking the offending element and naming the heuristic it breaks.
click violating elements in the live flow; tag each with a heuristic and a severity rating
an expert-authored full violation map revealed after submission, a precision/recall score against the learner's tags, and a cross-learner heatmap of most-missed heuristics
flow picker (3 seeded flawed flows); heuristic set (core 5 / full 10); severity-rating requirement on/off
