Use whenever an analysis makes or implies a CAUSAL claim — "the effect of", "X caused Y", "the policy raised", "the treatment increased", "because we did X, Y changed" — or whenever you're running difference-in-differences, event studies, instrumental variables, regression discontinuity, matching, synthetic control, or panel fixed-effects models. Forces the identification strategy and its assumptions to be stated and tested BEFORE estimating, and treats the design-specific robustness suite (parallel trends, first-stage strength, manipulation tests, balance, placebo, sensitivity) as mandatory, not optional. Use in R, Julia, or Python even when the user just says "regress Y on X", "did it work", or "estimate the impact" — a regression coefficient is not a causal effect until the design earns it.
