Use case: Shopify / product not received
Receiver lane: a customer claims “it never arrived.” Shopify-style dispute review often starts with loose tracking screenshots instead of a decision-ready delivery chain.
Review Rail flow
- The Gate: reject naked tracking alone and require the original proof-of-delivery PDF.
- The Join Layer: match the shipping ZIP in the carrier proof against the billing address snapshot from the order.
- The Decision Surface: show shipping=billing alignment + signature captured + one bounded “Accept representation” action.
