WhiteFin Execution Proof Objects and RFC-0509
Public Mapping Summary v1.0 — Published
Joint bilateral technical mapping between 3PMobile and WhiteFin. RFC-0509 Receiving-Boundary Reliance Grammar authored by Peter Cranstone, 3PMobile. WhiteFin is the proof-side system whose selected execution-proof objects were mapped.
The mapping
WhiteFin's execution-proof objects were mapped to the public RFC-0509 Receiving-Boundary Reliance Grammar — authored by 3PMobile — in a controlled bilateral exercise, as one concrete example of how a proof-side object can be described within that grammar. The mapping classifies which attributes of the objects a receiver can verify from the object itself and which remain producer-declared, while preserving the distinction between proof-side presentment and a receiving domain's own reliance decision. It is a technical classification only: it is not a certification, endorsement, or conformance approval, it determines no receiver-side outcome, and mechanical verification of the reviewed synthetic objects does not demonstrate production deployment or customer activity.
