Every eligible 10,000-hour residence enters the register; favorable cases cannot be selected.
Take it away.
Measure the absence.
Novelty can create enthusiasm. A neutral 168-hour absence tests whether the robot has become part of daily life. Profile 0.2-W1 binds every eligible lifetime completion, forbids substitutes and inducements, and reproduces both return requests and final reacquisition.
Absence without
contamination.
The robot stays unavailable for the entire window even if its return is requested early. Ordinary compensation, human support, and household conditions remain unchanged.
No replacement robot, compensation change, researcher contact, support, or early reinstall.
Start within 24 hours, remain absent for 168 hours, then record the final choice within 24 hours.
Rebuild request timing, day-seven return requests, final reacquisition, and censor-aware median.
Ask for it.
Then choose it.
A return request during absence and a final reinstall choice at day seven answer different questions. Both are reported; neither modifies the WANTED Score.
The median is null—not fabricated—until at least half of completed participants request return. Reacquisition is final reinstall choices divided by completed withdrawals.
Paste the register.
Rebuild the result.
The checker validates every clock, contamination control, choice, evidence binding, and claimed aggregate locally.
A person may request return because the robot is useful, emotionally meaningful, routine-forming, or difficult to replace. WANTED reports the behavior without claiming why it occurred.
