1/*2 * DE4SDV method process — iteration sequence of the DE4SDV increment workflow.3 *4 * This package models the 13-phase increment workflow from5 * methodologies/sysmod-sysmlv2/increment-workflow.md as a SysML v2 model.6 * The phase sequence and feedback loops are documented in7 * methodologies/sysmod-sysmlv2/process-mapping.md (PR #74) as a mermaid8 * diagram. This SysML model provides the structured data: phase enumeration,9 * SAF domain mapping, required trace chain, recurring logical-to-software10 * signal-mapping control, and increment size guidance.11 *12 * Source: methodologies/sysmod-sysmlv2/increment-workflow.md13 *         methodologies/sysmod-sysmlv2/process-mapping.md14 */1516package DE4SDV_MethodProcess {17  private import Views::*;18  private import SAF_Viewpoints::*;19  private import DE4SDV_Stakeholders::*;2021  /* ─── Method phases ─── */2223  enum def MethodPhase {24    doc /* The 13 phases of the DE4SDV increment workflow. */2526    phase0_incrementFraming {27      doc /* What are we changing or learning?
