//! Service-result assembly for `/debug/schema` report loading.
//!
//! This module maps per-client report-loader results into service-layer report
//! results while staged payload assembly is delegated to
//! `debug_service_result_stage_input_assembly`,
//! `debug_service_result_stage_output_assembly` and final stage-output handoff
//! is delegated to the stable facade in
//! `debug_service_result_from_stage_output_assembly`, which delegates to
//! `debug_service_result_stage_output_handoff_assembly`.
