Human-gated residual attestation. Nothing else.

Evidence-bound verification records for B2B. Residual is software for residual attestation — not carbon credits, not investments, not a market.

Evidence-bound

Every record carries a parcel AOI, site photos, and labeled NDVI evidence.

Human-gated

Drafts do not become issued records without an explicit approve or reject.

Cryptographically signed

Issue generates an Ed25519 proof over a SHA-256 payload and evidence Merkle tree.

How a record is issued

  1. 01

    Draft

    Bind a subject, parcel AOI, and site photos. Model 3 projects prefill known sites.

  2. 02

    Human gate

    A reviewer approves or rejects. Nothing issues without a person. That is the product.

  3. 03

    Issue

    An issued record gets an Ed25519 proof, a Merkle commitment of evidence, and a public verify URL.

  4. 04

    Verify

    Anyone with the link can inspect status, evidence, forbidden claims, and the gate audit.
