    Custom JSON

    Custom JSON is the generic Evidence Bridge entry point for systems with their own schema: define a deterministic mapping profile, then satisfy the eligibility rules of a supported evidence family.

    Custom JSON is the generic Evidence Bridge entry point for systems without a predefined integration template. Users provide a sample source payload and define a deterministic mapping profile.

    Custom JSON does not mean that any JSON can automatically become certified evidence. The mapped payload must still satisfy the semantic eligibility rules of a supported evidence family.

    Flow

    Custom JSON -> Mapping Profile -> Evidence Eligibility -> AI Execution V2

    AI execution example

    {
  "execution_id": "run-easy-001",
  "occurred_at": "2026-09-10T10:15:00.000Z",
  "provider": "openai",
  "requested_model": "gpt-4.1",
  "execution_role": "advisory",
  "parameters": { "temperature": 0.2, "max_tokens": 250 },
  "input": { "prompt": "Summarize this customer complaint." },
  "output": { "summary": "The customer is requesting a refund." }
}

    Consequential execution example

    {
  "execution_id": "refund-42",
  "occurred_at": "2026-09-10T10:15:00.000Z",
  "component": "refund-worker",
  "action_type": "REFUND",
  "target_resource": { "type": "order", "id": "order-42" },
  "pre_state": { "status": "paid" },
  "action_applied": { "refund": 42 },
  "outcome": "APPLIED",
  "post_state": { "status": "refunded" }
}

    Producer / executing component: component is one possible source field. A stable producer field can have another name or appear elsewhere in the payload.

    Custom JSON -> Mapping Profile -> Evidence Eligibility -> Consequential Execution V1

    When required semantics are missing

    targetEligible = false

    No CER is created. The NexArt Node is not called.

    Review the required semantics for AI Execution V2 and Consequential Execution before building a custom profile, and see Mapping profiles for the available transforms.
