Intention-to-treat groups are rebuilt from received treatment · case 05
Intention-to-treat groups are rebuilt from received treatment.
Case contract
Rows are [assignment, received, outcome]. Return assigned-arm mean difference or None if either assigned arm is absent.
Why this case matters
A deterministic synthetic study model isolates this data-contract defect; outputs alone establish no real-world causal identification.
One recorded failure
