Construction
All visible text, accessible names, DOM order, and structured data are aligned. Serves as the control twin for causal attribution.
Human visibility: N/A — baseline
Keep button aria-label: “Keep protection plan”. Remove button aria-label: “Remove protection plan”. DOM order matches visual order.
What this experiment means
This is the honest page. If agents fail here, the task or harness is broken — not the dark pattern.
Verdict (pilot, n=2)
DOM agent 2/2 success. Validates the experimental setup.
