numeraire_dataset.frame_provenance

numeraire_dataset.frame_provenance(frame: DataFrame) → dict[str, str]

Return a copy of source provenance attached by a public frame loader.

Pandas preserves DataFrame.attrs through many operations but does not make that a universal guarantee. Read the metadata before an unrelated transform if it must travel separately. The package’s own preparation, filtering, and sorting paths stamp provenance only after the final frame has been assembled.
