# Arc CPN Corridor Economics Model — attested computation

> §10.2 Attested Computation binding for [Arc CPN Corridor Economics Model](../tools/art-43-arc-cpn-model.md).

## Executor

Kernel source: `chaingraph/kernels/art-43-arc-cpn-model.kernel.mjs`. A §18 zkVM compute-integrity
proof, when attached to an artifact this kernel produced, carries these receipt fields:
`type`, `system`, `receiptFormat`, `imageId`, `seal`, `journal` (SPEC.md §18.0).

## Attester

Kernel identity: `sha256:b63c0541028ab8fc4734ed626c01d898b2248c38df45a7136d68bc76669a4f91` (SPEC.md §17.1 `compute_images`) — a
content-addressed digest of this node's deployed kernel source, already published in the
Graph Index. Static and dereferenceable; nothing in OpenChainGraph verification depends on
this OKF bundle, and this concept asserts no execution event or `verified:` status.
