Use preparedAnalysisEvidence from the validated exact recommendation detail, including its optional account-attribution and future-risk-target sections, to prepare the member-account handoff. Deterministic totals, ordering, thresholds, reconciliation, and materiality are consumed and checked from prepared evidence; agents handle only ambiguous eligibility and exceptions. Bounded read-only Cost Explorer attribution remains a fallback for absent, stale, mismatched, or explicitly overridden evidence.
Reuse prepared attribution
Preserve exact account totals, service/Region scope, risk signals, selection policy, and optional targets when fingerprints and plan identifiers match.
Fallback safely
Query only the missing or invalid dimensions when prepared evidence cannot support the requested decision.
Publish material investigations
Emit the existing canonical handoff without allocating organization commitment or savings to members.
