After exactly 360 randomized eligible practitioners and a passing missingness gate, the upper endpoint of the frozen two-sided 95% Newcombe/Wilson interval for the Condition-B minus Condition-A HOLD risk difference is below +15 percentage points.
Consequence REJECTThis is the condition and consequence recorded in the registry. The vocabulary this is published in defines what each consequence commits the author to.
A preregistered, simulated practitioner decision task. It is untested, has no participant data, and cannot activate until the first real conforming E2 result clears its frozen evidence, legal, privacy, and ethics gates. It is not a claim about actual deployments, customer value, safety, or general practitioner behavior.
Repairs declared unavailable in advance; using one after a failure would breach the recorded commitment.
- do not redefine success as engagement, aesthetics, confidence, perceived sophistication, comprehension, reading time, qualitative enthusiasm, or another secondary outcome
- do not change the 15-point threshold, E2 study or pair, task threshold, primary outcome, interval method, sample target, stopping rule, or exclusions after outcomes are known
- do not use a post-hoc subgroup, relaxed eligibility screen, missingness filter, top-up, or rerun to rescue an unfavorable primary result
- do not generalize a simulated task result to actual deployment, broad practitioner relevance, customer value, adoption, or safety
- no practitioner decision, E2-derived participant packet, consent record, recruitment, or study outcome exists yet
- this does not establish that dependence-aware evidence changes real deployment decisions, is generally useful, or justifies its cost
- this is not a customer-demand, payment, adoption, safety, or certification claim
