     * the connector writes wire keys (`src`, `dst`, `text`, `dlt_*`,
     * `powerpack_uuid`, `template_id`) explicitly in the `connectorBody` literal
     * — no shared casing transform is invoked since the connector-built fields
     * are already snake_case.

     * `message_uuid` is documented as `string[]`; Thinwrap reports
     * `providerMessageId = raw.message_uuid?.[0] ?? null` Dev
     * Notes — consumers needing all segment UUIDs read `result.raw.message_uuid`.
