Enum ResponseColumnKind 

pub enum ResponseColumnKind {
    Numeric,
    Binary,
    Categorical {
        levels: Vec<String>,
    },
}

Caller-supplied description of the response column’s source kind.

Categorical { levels } flags a column that arrived as non-numeric strings (the ingest layer encoded its levels to 0.0, 1.0, ... indices) — the levels list is preserved so the auto-inference refusal can echo them back to the user verbatim. Binary is the ingest-layer signal that a numeric column already contains only {0, 1} (used to short-circuit the scan inside ResponseFamily::infer_from_response). Numeric is the generic continuous case.
