Field notes
Each entry is a re-implementation of an evaluator's published analysis, with source-linked model pages and spreadsheet/model files. Readers can alter exchange rates between human health and animal welfare, choose whether to count staff salary sacrifice, and decide how to credit outcomes shared with other organizations; rankings recompute under those choices. The displayed ranges set all inputs to their low or high ends together, a broad stress test rather than a probability interval.
