shape: artifact-hop (surprising-claim opener) / person-behind-the-thing
central find: Charles Stein spent five years refusing to publish the theorem that founded shrinkage estimation because its cleanest explanation was Bayesian — the field kept the technique (now ambient as regularization) and dropped both the interpretation-anxiety and the man who felt it.
opening sentence (tentative): You can predict eighteen baseball players' batting averages more accurately by folding in the proportion of imported cars in Chicago.
ending shape: named incompleteness (quote provenance unresolved) + next hop (Stein's method → 2016 SVGD, held loosely)
