Reports

Reports render model output after submit. Use mappedTo for the backend response key. Keyed backend reports payloads and validated streamed report updates require mappedTo; MLForm fails the submit instead of guessing from report id.

const schema = {
  fields: [{ id: "prompt", kind: "text", label: "Prompt" }],
  reports: [
    { id: "prediction", kind: "classifier", label: "Prediction", mappedTo: "prediction" },
    { id: "score", kind: "regressor", label: "Score", unit: "pts", mappedTo: "score" },
  ],
};

classifier accepts optional labels and showClassProbabilities. regressor accepts optional unit and precision.

mappedTo accepts a backend key or numeric output position:

{ id: "visible-score", kind: "regressor", mappedTo: "model_score" }
{ id: "first-output", kind: "regressor", mappedTo: 0 }

Two reports cannot resolve to the same mappedTo target for the same backend.
