//! Health-assessment assembly for `/debug/schema`.
//!
//! This module composes overall health label and structured health reasons from
//! summary metrics, isolating health-policy orchestration from summary payload
//! construction, while staged payload assembly is delegated to
//! `debug_health_assessment_stage_input_assembly`,
//! `debug_health_assessment_stage_output_assembly` and final staged handoff is
//! delegated to the stable facade in
//! `debug_health_assessment_from_stage_output_assembly`, which delegates to
//! `debug_health_assessment_stage_output_handoff_assembly`.
