Function computed_values 

pub fn computed_values(
    spec: &ModelSpec,
    table: HostTable,
    positions: usize,
) -> Option<Vec<f64>>

The values of a host table the spec alone gives (every one but a rotary table, whose frequency factors a checkpoint may hold): a decode step’s caches of positions rows, or a forward’s one row. None for a rotary table, or for a temperature table of a model that has none.
