      "value": "Proposed Confluence plugin architecture: the diagram's small source model (systems/interactions, no geometry) is versioned with the Confluence page; precomputed vertex positions and routed edges are cached separately, keyed by a hash of the source model and routing-engine version, so a Reader's page view never has to re-run libavoid/OVGRouter routing — only an Editor's change (or a cache miss) does.",
