        "The diagram fits on one screen; beyond roughly 15 nodes it is split into separate Context and Container diagrams rather than crammed",
        "Arrows show direction of data flow, not undirected connections",
        "Every arrow crossing a trust boundary is labelled",
        "The diagram is generated from the written description provided — no components are invented beyond it",
        "A named format is produced (Mermaid, PlantUML, or C4) and renders as valid syntax"
