Minimal Example Diagram

The diagram below names the composite approval path that the book reuses in later chapters.

flowchart LR
  CR[Change Request] -->|draft-review-plan| RP[Review Plan]
  RP -->|human-approval| AC[Approved Change]
  CR -->|policy-gated-approval| AC

The direct edge policy-gated-approval stands for the composition of draft-review-plan and human-approval. This gives the reader one stable claim to revisit in later chapters.
