The 24-artefact, hash-sealed, signed record that ships with every Importable delivery.
An ordered set of 24 typed artefacts covering one trade from harvest to settlement — GPS at harvest, cooperative ID, cold-chain sensor stream, QC inspector signature, BTOM clearance, SWIFT confirmation, and so on. The artefact set is hashed (SHA-256), the hashes are assembled into a Merkle tree, and the root is signed with the Rotterdam hub's Ed25519 master key.
The crate is the commodity — figs from Izmir cost what figs from Izmir cost. The pack is what differentiates Importable: the buyer is paying for verifiability, not for any single artefact. Every claim on the crate label, the menu, the audit log, can be checked back to its source.
In Cloudflare R2 (private bucket for raw artefacts, public bucket for anonymised PDFs), referenced by trade ID at verify.importable.io/pack/<id>. The pack URL is itself artefact #24, so every pack is self-referential and externally addressable.
Three independent surfaces: paste a hash at verify.importable.io, GET the JSON via /api/v1/pack/<trade_id>, or use the open-source @importable/verify npm client. The full spec is at /standard/v1.
