    • Readonlymessage: string

      Plain English, so a consumer that only prints strings still works.

    • Optional ReadonlyoptionPath?: string

      The setting this concerns, in the vocabulary of the output options.

    • Optional Readonlyorigin?: DiagnosticOrigin

    • Readonlyseverity: Severity

      Plain JSON — a report may cross a worker boundary or be stored.

      • distance: number

        How far the estimate sat from the palette, and how far it had to sit to be taken.

      • estimate: string

        0..1 — how strongly the readings constrained this key.
