Transfer with missing attribution

A successful transfer omits the expected Builder Code.

Offline validation checks internal consistency. Imported acquisition and policy remain producer claims. Read the collection and recheck guide.

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.
