jared a28fb2e19b chore(fixture): regenerate against cog_pipeline Layer 1 + Layer 2 fixes
Refreshes the bundled fixture corpus against the upstream resolver fix
(gate place-less fallback to states/counties only) and the Phase O
extended FIPS xwalk (post-2012 incorporations, Utah metro townships,
Connecticut planning regions). After regeneration:

- Salt Lake County now resolves to 20 distinct cities/townships instead
  of collapsing six into Midvale's canonical_govid.
- Zero govs with conflicting populations within (year, canonical_govid).
- 593 new fips_extended canonical_govids in the xwalk (377 cities, 214
  townships, 2 counties).
- Sentinel count drops from 20-39/year to 2-3/year (the residual
  reflects type-2/3 entities with GOVS legacy_id but no FIPS triplet —
  a separate gap, documented in cog_pipeline).

manifest.json updated with fresh SHAs, sizes, row counts, and pipeline
commit reference.

All 283 uscogdata tests pass against the new fixture.

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)

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.
