Block invalid currency, negative costs, nonpositive capacity or contribution, fractional forecast orders, missing evidence, incomplete privacy or URL scope, duplicate scenarios, or open conflicts. Review valid packets that exceed retained-order or implementation limits or have negative forecast headroom. Ready is planning arithmetic, not migration authority.
