Returns the unique native values together with city/corner membership and
explicit acquisition gaps. No interpolation or implicit remote access occurs.
Derived time fields are decoded from preserved native offsets and bounds;
immutable raw artifacts are never rewritten. Selection receipts created with
an earlier CF decoder require a metadata recheck before reporting completion.
Climatological values retain time_kind = "climatology", original
climatology_bound_* values, native endpoints and ordered cell_methods.
climatology_bounds_dimensions contains JSON dimension names in the original
RNetCDF array order; climatology_bounds_time_dimension identifies the time
position, allowing exact reconstruction of the selected boundary array.
Time selection uses representative labels; their boundary span must not be
interpreted as continuous weather coverage. Missing or contradictory cached
statistical metadata raises an error.
read_subset(dest, case_id = NULL, site_id = NULL, variable = NULL, time = NULL)A list with values, neighborhoods, links and gaps.
gaps$incomplete_requests identifies selected requests whose exact native
coverage or checked selection receipt is missing, including empty native
windows. A later successful window never clears an earlier request's gap.
gaps$directory lists selected requests from incomplete or unknown File
directories, separately from native data coverage.
