This report presents a supplier evidence architecture model for EU-Brazil circular value chains. 

It also focuses on reverse logistics, e-waste, traceability, custody records, product data, due diligence files and board-level risk governance. 

The report introduces a diagnostic Supplier Evidence Failure Index (SEFI) as a non-certification framework for quantifying exposure created by fragmented documentation, weak traceability and governance latency. 

It concludes that regulatory clarity is the starting point but audit-grade evidence is required to support procurement review, buyer due diligence, regulatory defensibility, circular value chains and sustainable finance readiness.
