Get coefficients (progressive truth)
Return the inverse-variance weighted median coefficient per measurement series across computed experiments for the location. Weight = 1/se_coefficient² — precision, not effect size, so a huge noisy lift earns no extra say. Partial (mid-window) computes and poor-control-fit results are excluded. Each entry carries the series_key identifying the exact estimand (channel + revenue definition + spend scope/conversion).
