Block invalid rates
Block invalid currency, negative costs, rates outside 0–100%, nonpositive net contribution, invalid cycle or horizon, missing cohort evidence, ambiguous new-customer or attribution definitions, duplicate scenario labels, or open conflicts. Review valid packets that miss payback within the horizon, exceed the day limit, or fall below minimum headroom. Ready is not bidding authority.

Checkpoint 1 in the acquisition decision matrix 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.
For block invalid rates, keep spend, confirmed new customers, acquisition cost, first contribution, mature refund loss, repeat contribution, repeat probability, decay, cycle days, finite horizon, cumulative expected contribution, payback day, headroom, threshold, and conflict separate.
