jared aba7ffbac2 test: cover C1 direct-suppressed handling, C2 corpus guard, and I2 candidate filter
Adds regression coverage for the three preceding fixes:
- "total" on a legacy aggregate-only family (AL Corrections 2011) now
  fires recipe suggestions, flags provenance$expenditure_concept_direct_
  suppressed, and names a recovering recipe in the affected row's notes,
  plus a contrast test confirming the flag stays FALSE when the Direct
  leg is present.
- expenditure_concept = "total" aborts with class
  uscogdata_ig_categories_unsupported against a corpus whose
  summary_categories carries no M/L rows (new
  with_corpus_missing_ig_categories() fixture helper), is unaffected for
  "direct" on the same corpus, and still works on a corpus that does
  carry M/L rows.
- an M/L recipe (corrections_ig_local_combined) no longer appears as a
  raw suggestion for a Direct-flavored cog_spending() call.

uscogdata

Curated R reader for the Civilytics US Census of Governments finance corpus.

Provides unit-level financial profiles, geographic rollups, and peer comparisons with auditable provenance and built-in cross-vintage correctness. Reads the published corpus (Hive-partitioned parquet + manifest.json) directly from Nextcloud via DuckDB httpfs — no local bulk downloads required.

Status

Under active development (Phase 2 of the cog_pipeline project). See ../cog_pipeline/docs/reader-specification.md for the reader contract this package implements.

Installation

# pak::pkg_install("gitea.civilytics.org/Civilytics/uscogdata")

Configuration

  • USCOGDATA_URL — corpus root URL (public Nextcloud share, trailing slash)
  • USCOGDATA_CACHE_DIR — optional override for the manifest cache directory
  • USCOGDATA_MANIFEST_TTL_SECS — optional manifest re-fetch TTL (default 3600)

Direct vs Total spending

cog_spending(..., expenditure_concept = c("direct", "total")) controls whose spending a result counts. "direct" (the default) is a government's own current operations, capital outlay, and other direct spending. "total" additionally adds in the intergovernmental legs — money it hands to other governments to spend on its behalf — which is meaningful for describing one government's own budget over time, but double-counts when summed across governments (a state's payment to a county is the same dollar the county reports as its own direct spending).

Rule of thumb: any figure that spans more than one government uses direct. cog_geographic_rollup() and cog_peer_compare() enforce this by refusing expenditure_concept = "total". See vignette("total-spending", package = "uscogdata") for the full explanation with worked examples.

Developer notes

Testing

The package ships a bundled fixture corpus at inst/extdata/fixture_corpus/ — a 3.6 MB two-year slice (2019 + 2020) of the full corpus covering all 50 states. tests/testthat/setup.R automatically points USCOGDATA_URL at this fixture, so the full test suite runs offline with no network dependency:

devtools::test()   # uses bundled fixture, no credentials required

Releasing against the live corpus

Before cutting a release, run the test suite against the published corpus to catch any drift between the fixture and the real data:

Sys.setenv(USCOGDATA_URL = "<published-corpus-url-with-trailing-slash>")
devtools::test()

When the live-corpus run is clean, strip the fixture from the built package by adding this line to .Rbuildignore:

^inst/extdata/fixture_corpus$

The test suite is URL-agnostic — setup.R falls back to USCOGDATA_URL when the bundled fixture is absent, so no test code changes are needed for the release run or after stripping the fixture.
