stale_def_keys(
    residuals ,
    coord_dims_map: Mapping ,
    columns ,
)-> ‘list[str]’

The def-key columns which describe coordinates a residual will trim.

A residual selection is applied when a patch is loaded, so until then the identity claims (def keys) of coordinates on the trimmed dimensions describe the untrimmed values and must not be compared or published.
