Struct FetchedChart 

pub struct FetchedChart {
    pub spec: ChartSpec,
    pub sources: IndexMap<String, DataTable>,
    pub metadata: FetchMetadata,
}

Stage 1 output: the spec plus every named source resolved to a DataTable.

sources always has at least one entry. The key is the user-chosen name from the YAML data: map; for unnamed flat data the canonical key is "source". Insertion order matches the YAML — preserved via IndexMap so transform middleware can rely on stable ordering.

Fields

spec: ChartSpec

sources: IndexMap<String, DataTable>

metadata: FetchMetadata
