Playbook: validate your supply chain object end to end

Playbook: validate your supply chain object end to end
Heard: buyers are now hard-rejecting requests where schain nodes don't reconcile with sellers.json.

— Confirm every node's sid exists in that intermediary's sellers.json
— Check complete: 1 only when the first hop is the publisher
— Verify hp: 1 on every node in the payment path
— Match the domain in each node to the seller's declared domain
— Drop any path where a node can't be resolved

Impact: a broken schain reads as obfuscation and gets your supply demoted. sourced
