v0.4.3 — Integrity release

v0.4.3 (2026-05-28)

Integrity release. Two dw_use() fixes (issues
#30 +
#31) ported from
the DW-Production NT reviewer-mode reproducibility audit on 2026-05-27
(PR #33; DW-Production
PR #133). Both
landed first on the DW-Production vendored copy as local_edits; this
release lets the next cso_toolkit_pull(target_version = "v0.4.3") drop
those local edits.

Issue #32
(provenance sidecars) is the design-foundation companion in the same
milestone; implementation ships in a follow-up PR.

dw_use() — parquet / dta col_select = NULL conditional dispatch (issue #30)

The v0.4.2 parquet branch unconditionally passed col_select = cols
to arrow::read_parquet(). When a caller invoked dw_use(path) without
explicit columns, cols defaulted to NULL, and
arrow::read_parquet(path, col_select = NULL) returned a zero-column
schema rather than all columns. The same pattern affected
haven::read_dta(col_select = NULL). Both branches now use conditional
dispatch: pass col_select only when cols is non-NULL.

Surfaced empirically by DW-Production Run #6 (NT pipeline): 13+ stages
downstream of 1b_cmrs_series_import.R failed with "object 'COLUMN'
not found" because the upstream dw_use(out_dw_nut_*.parquet) returned
an empty tibble. After the fix (Run #7): 24/25 stages OK.

dw_use(cols_lenient = FALSE) — new flag for any_of()-style schema intersect (issue #31)

Sector scripts that wanted "select these columns if present, ignore
the absent" semantics passed dw_use(cols = dplyr::any_of(c(...))).
any_of() errors fatally outside a tidyselect selecting context
(tidyselect >= 1.2.0); R evaluates the helper before the call to
dw_use, so no lazy-eval trick inside the toolkit can save it.

New cols_lenient = FALSE parameter (default off for backwards compat).
When TRUE, dw_use introspects the file schema cheaply (parquet
metadata, csv / tsv / xlsx zero-row read, dta header) and intersects
the requested cols with the actual columns before the data read.
Empty intersection → warning + read all columns (forward-progress
guarantee). New internal helper .dw_schema_cols(path, fmt) performs
the schema-only read.

Migration:

• dw_use(cols = dplyr::any_of(c(...))) → dw_use(cols = c(...), cols_lenient = TRUE)
• dw_use(cols = dplyr::all_of(c(...))) → dw_use(cols = c(...)) (strict; all_of() at top level is deprecated in tidyselect 1.2.0 anyway)

Companion issue: provenance sidecars (issue #32)

Issue #32 sketches the producer → reviewer → ingestor integrity chain
that .write_remote_provenance (v0.4.0, URL-freeze sidecars) is the
seed of. Foundational design captured; implementation deferred to a
follow-up PR within the v0.4.3 milestone.
