Evidence and limits
Finding: Complementarity is not always achievable, and lower average loss can conflict with fair distribution of benefit or increase group error disparities.
Impact: Strengthen impossibility checks and subgroup outcomes. Reject average complementarity as sufficient benefit.
Boundary: The model abstracts human behavior and task structure. Next: which empirical conditions reveal that a workflow cannot beat its better component?
Flags: modeled losses and groups; no open-ended workflow
Record State: Catalog review recorded; not a performance endorsement
What was reviewed: Structure and relevance screened; not a full evaluation
