Cluster randomization accepts contradictory unit assignments · case 05
Cluster randomization accepts contradictory unit assignments.
Case contract
Rows [cluster,arm] use arms 0 and 1. Return sorted clusters violating the cluster-level assignment design.
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
Sample boundary fixtureThis sample comes from the broken implementation of a controlled reproducer.
