UI9000 workspace MCP. One tool, show_workspace, draws a chart from your table. Set TYPESAFE_API_KEY to let Jev choose the chart.

// A map chart whose geospatial values resolve to (almost) no boundaries — the
// field is the wrong admin level, or the values aren't real regions. We refuse
// to sign the data-link and surface the actionable message so the model
// regenerates correctly, instead of MCP silently rewriting the user's data.

    }
}
// Block only when a layer renders essentially nothing (≤10% of values match),
// not on every partial mismatch — a correctly-typed map that joins most of its
// values must still sign, or the model would loop on the few unmatchable ones.
