Constant REPORT_RESULT_NAME 

pub const REPORT_RESULT_NAME: &'static str;

The well-known result_name the scheduler and API use to identify a report envelope among a task’s outputs. Defined in malbox-plugin-transport so the SDK and scheduler share the same constant without a direct dep. Well-known result_name for a plugin’s structured report envelope.

Shared constant so the SDK (producer) and scheduler (consumer) agree without either needing to depend on the other. The scheduler uses this to tag matching task_results rows with role = 'report'.
