Run a reusable payer-first investigation that consumes matching cost-scanner preparedAnalysisEvidence attached to an exact AWS Compute, EC2 Instance, Database, or SageMaker Savings Plan recommendation, validates the pinned recommendation and deterministic candidate grid, selects accounts from prepared attribution when available, investigates ambiguous member workload persistence, and produces either the highest confidently supported evaluated commitment percentage, an explicit scanner-evaluated 0%, or a needs-refresh result when decision-grade scanner evidence is unusable. Organization commitment and savings are never allocated to member accounts.
