It reports when cumulative expected contribution crosses the entered acquisition cost under a finite aggregate cohort model. It cannot prove attribution or incrementality, predict an individual customer, value an infinite lifetime, guarantee repeats, determine cash timing, authorize advertising, or establish accounting profit. Ready still requires current sources, ownership, monitoring, stop conditions, and restoration.

It reports when cumulative expected contribution crosses the entered acquisition cost under a finite aggregate cohort model. It cannot prove attribution or incrementality, predict an individual customer, value an infinite lifetime, guarantee repeats, determine cash timing, authorize advertising, or establish accounting profit. Ready still requires current sources, ownership, monitoring, stop conditions, and restoration. Separate deterministic expected contribution from attribution proof, individual behavior, infinite lifetime value, cash, and accounting. Checkpoint 1 in the acquisition interpretation memo records acquisition source, campaign dates, new-customer rule, attribution boundary, cohort maturity, currency, first and repeat contribution conventions, refund versions, probability model, owner, reviewer, authorization boundary, monitoring trigger, and restoration before interpretation.
