Scope and limitations

Coverage describes only the explicitly supplied transaction set; producer-declared completeness is not independently established.
Builder-Code-filtered selection cannot measure omitted attribution outside the supplied set.
Token reads describe end-of-block state. Reverted calls without earlier creation evidence remain unresolved at transaction time.
Receipt events in routers or batches do not establish attribution for a nested application or UserOperation.
Acquisition and policy in an imported artifact are producer claims. Offline validation cannot grant current-run RPC authority.
Application readiness, deployment activation, consensus proofs, ownership, and reward eligibility are not tested.
