The verifiable record for recovered food. A twin is born with each batch at the field scale, grows with every reading, and seals into the claim. Proof, not paper.
Think of it as the batch's passport: issued at the field scale, stamped at every stage, append-only by design.
Stage 01 · field · illustrative, not from the record
Each stage writes another vector into the same object. At issuance it seals: one of one, append-only by design, never split from any credit issued under a certified methodology.
The credit and the batch are the same object. Carbon is the first claim it carries, not the last.
The record lives on public, content-addressed storage: change a byte and the reference changes. FFD writes it. By design, its sealed history belongs to whoever holds the twin.
