Measurement Uncertainty Budget

Evox governance framework managing data opacity as a permanent physical constraint rather than an operational failure to be eliminated. Establishes the exact ceiling of uncertainty an investment decision can tolerate and allocates measurement expenditures (server-side tracking, incrementality testing, geo-lift experiments, marketing mix modeling, customer surveys) against that boundary. Reformulates stage X0 of Marketing Engineering™: when signal loss is structural, the objective is not impossible perfection, but bounding opacity to what executive decisions require.
